METHODS： Infected livers and lungs from slaughtered animals, 10 bovine and two ovine, were collected. Cysts were photographed, and their volume, cyst content, germinal layer adhesion status, wall calcification and presence of daughter or adjacent cysts were evaluated by ultrasound. Some cysts were treated with RTA at 150 W, 80℃, 7 min. Temperature was monitored inside and outside the cyst. A second needle was placed inside the cyst for pressure stabilization. After treatment, all cysts were sectioned and examined by histology. Cysts were defined as alive if a preserved germinal layer at histology was evident, and as successfully treated if the germinal layer was necrotic. RESULTS： The subjects of the study were 17 cysts （nine hepatic and eight pulmonary）, who were treated with RTA. Pathology showed 100% success rate in both hepatic （919） and lung cysts （8/8）; immediate volume reduction of at least 65%; layer of host tissue necrosis outside the cyst, with average extension of 0.64 cm for liver and 1.57 cm for lung; and endocyst attached to the pericystium both in hepatic and lung cysts with small and focal de novo endocyst detachment in just 3/9 hepatic cysts. CONCLUSION： RTA appears to be very effective in killing hydatid cysts of explanted liver and lung. Bile duct and bronchial wall necrosis, persistence of endocyst attached to pericystium, should help avoid or greatly decrease in v/vo post-treatment fistula occurrence and consequent overlapping complications that are common after surgery or percutaneous aspiration, injection and reaspiration. In vivo studies are required to confirm and validate this new therapeutic approach.展开更多

Potential complications of RFA include liver abscess, ascites, pleural effusion, skin burn, hypoxemia, pneumothorax, subcapsular hematoma, hemoperitoneum, liver failure, tumour seeding, biliary lesions. Here we describe for the first time a case of biliary gastric fistula occurred in a 66-year old man with a Child＇s class A alcoholic liver cirrhosis as a complication of RFA of a large hepatocellular carcinoma lesion in the nl segment. In the light of this case, RFA with injection of saline between the liver and adjacent gastrointestinal tract, as well as laparoscopic RFA, ethanol injection （PEI）, or other techniques such as chemoembolization, appear to be more indicated than percutaneous RFA for large lesions close to the gastrointestinal tract.展开更多

Nevertheless, ablative therapies are not yet considered as effective options because their efficacy has never been proved by randomized controlled trials (RCT). However, there are in literature no trials that failed in demonstrating the effectiveness of ablative treatments: what are lacking, are the trials. All the attempts to organize phase III studies on this topic failed as a result of non accrual. Just one prospective RCT comparing radiofrequency ablation combined with systemic chemotherapy vs chemotherapy alone has been published. It was designed as a phase III study, but it was closed early because of slow accrual, and was downscaled to phase II study, with the consequent limits in drawing definite conclusions on the benefit of combined treatment. However, the combination treatment met the primary end point of the study and obtained a significantly higher 3-year progression-free survival than systemic chemotherapy alone. It is very unlikely that ultimate efficacy of ablation treatments will ever be tested again, and the best available evidence points toward a benefit for the combination strategy using ablative treatments and chemotherapy.展开更多

However, the therapeutic strategies of the rare liver tumors remain limited. Methods: We analyzed twelve pathologically confirmed rare liver tumors in 8 patients. All of the patients underwent ultrasound(US) guided biopsy and subsequent thermal ablation. The tumors were ablated according to the preoperative plans and monitored by real-time US. CT/MRI fused with contrast enhanced US(CEUS) or three-dimensional(3 D) US-CEUS images were used to guide and assess the ablation zone more accurately during thermal ablation. The rate of technical efficacy was assessed based on the contrast-enhance CT/MRI(CECT/MRI) results one month after ablation. Local tumor progression(LTP), recurrence and complications were followed up and recorded. Results: Among these twelve nodules, nine were subject to US-guided thermal ablation, whereas the other three inconspicuous nodules were subject to CEUS-guided thermal ablation. Intra-procedure CT/MRI-CEUS or 3 D US-CEUS fusion imaging assessments demonstrated that the ablation zone sufficiently covered the original tumor, and no immediate supplementary ablation was required. Additionally, no major complications were observed during the follow-up period. The postoperative CECT/MRI confirmed that the technique success rate was 100%. Within the surveillance period of 13 months, no LTP or recurrence was noted. Conclusions: US-guided thermal ablation was feasible and safe for rare liver tumors. The use of fusion imaging technique might make US-guided thermal ablation as effective as surgical resection, and this technique might serve as a potential therapeutic modality for rare liver tumors in the future.展开更多

Most recipients are women of reproductive age who, as reported in the literature, may be at risk of adverse pregnancy outcomes. This study investigated the risk of abortions, prematurity, stillbirths, and prolonged labor among reproductive-age women following Cryotherapy, Thermal ablation, and Loop Electrosurgical Excision Procedure treatments in Zambia. Methods: This cross-sectional study analyzed records of 8000 women aged 15 - 49 years at the Adult Infectious Disease Control Centre using records between January 2010 and December 2020. Women constituting the treatment group were all respondents treated by cryotherapy, thermal ablation, and LEEP, while the control group were VIA negative women. Women from both groups were invited to answer a phone survey. Data were analyzed using Stata version 16;descriptive analysis estimated the prevalence and obtained the frequency distribution of abortion, prematurity, prolonged labor and fresh stillbiths. Chi-square and Fisher’s exact test established the associations of CIN and APOs at 95% Confidence intervals. Univariate and multivariable binary logistic regression estimated the odds of adverse pregnancy outcomes across the three treatments. Results: Adverse pregnancy outcomes were more prevalent in the treatment group (39.2%) compared to the untreated group (16.9%). Across the two groups, normal outcomes were lower in the treated (42.3% vs 57.7%). The treated group accounted for the majority of abortions (74.5% vs 25.5%) and prolonged labor (72.5% vs 27.5%), while the untreated group accounted for higher proportions of stillbirths (66.7% vs 33.3%) and prematurity (53% vs 47%). Adverse pregnancy outcomes were five and two times more likely in women treated with thermal ablation (aOR = 5.05, 95% CI = 4.01 - 6.36, p Conclusion: Cervical treatment among Zambian women increases the risk of abortion and prolongs labor. Therefore, caution should be taken when administered to those of reproductive age. Vigilant monitoring should be maintained during pregnancy, delivery, and postpartum to improve maternal and neonatal health.展开更多

Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.展开更多

文摘Colorectal cancer(CRC)with lung oligometastases,particularly in the presence of extrapulmonary disease,poses considerable therapeutic challenges in clinical practice.We have carefully studied the multicenter study by Hu et al,which evaluated the survival outcomes of patients with metastatic CRC who received image-guided thermal ablation(IGTA).These findings provide valuable clinical evidence supporting IGTA as a feasible,minimally invasive approach and underscore the prognostic significance of metastatic distribution.However,the study by Hu et al has several limitations,including that not all pulmonary lesions were pathologically confirmed,postoperative follow-up mainly relied on dynamic contrast-enhanced computed tomography,no comparative analysis was performed with other local treatments,and the impact of other imaging features on efficacy and prognosis was not evaluated.Future studies should include complete pathological confirmation,integrate functional imaging and radiomics,and use prospective multicenter collaboration to optimize patient selection standards for IGTA treatment,strengthen its clinical evidence base,and ultimately promote individualized decision-making for patients with metastatic CRC.
文摘Ultrasound-guided percutaneous thermal ablation has gained popularity as treatment for malignant hepatic tumors.It was first introduced as ablation therapy for hepatocellular carcinoma and cirrhosis comorbidity.Recently,this technique has also been used in the treatment of intrahepatic cholangiocarcinoma for patients who are not eligible for surgical resection.There are several types of thermal ablation techniques.Radiofrequency ablation and microwave ablation are two common methods that induce necrosis of the lesions.Irreversible electroporation is a relatively new non-thermal technique and is suitable in cases where thermal ablation would be ineffective or dangerous(e.g.,malignant tumors close to vascular or biliary structures).Irreversible electroporation can induce tumoral necrosis without damage to vascular and biliary structures.The aim of this minireview was to describe the safety,efficacy,and clinical indications of these techniques in the treatment of patients with intrahepatic cholangiocarcinoma who are ineligible for surgery.
文摘BACKGROUND Recurrence prediction of hepatocellular carcinoma(HCC)after thermal ablation represents a challenge that can impact patients'quality of life.Artificial intelligence(AI)-based radiomics models applied to various imaging modalities can improve recurrence prediction,therefore guiding therapeutic decisions.AIM To evaluate the effectiveness of AI-driven predictive models in predicting HCC recurrence.METHODS A systematic literature search in PubMed and Scopus was performed,and a total of ten studies were included in this systematic review.All studies included response prediction evaluation with AI models for patients who underwent thermal ablation for HCC.Deep learning and machine learning algorithms were utilized to evaluate the predictive performance and accuracy through metrics such as the area under the curve and concordance index.RESULTS The developed models demonstrated high accuracy in predicting local progression and recurrence,allowing a solid risk stratification.In particular,the integration of imaging data and clinical-laboratory variables optimized treatment selection,highlighting the superior ability of imaging models to predict therapeutic outcomes compared to clinical parameters alone.Furthermore,radiomic analysis of follow-up imaging enabled highly accurate detection of ablation site recurrence.CONCLUSION AI-driven predictive models based on multimodal radiomic analyses integrated with clinical data represent promising tools for predicting tumor recurrence after thermal ablation in HCC patients.
文摘BACKGROUND Thermal ablation(TA),including radiofrequency ablation and microwave ablation,is a commonly used curative treatment for single small hepatocellular carcinoma(sHCC).The relative advantages of TA and surgical resection(SR)in terms of long-term survival remain controversial.AIM To compare their long-term efficacy in this patient population.METHODS This population-based retrospective cohort study included 257 patients who received a first diagnosis of single sHCC and underwent SR or TA from January 2012 to September 2017.The primary endpoints were overall survival(OS)and recurrence-free survival(RFS).RESULTS The average follow-up duration was 11.4 years.The 1-,3-,5-,and 10-year OS rates were 95.8%,86.0%,82.5%,and 74.2%in the SR group vs 97.4%,85.8%,78.6%,and 65.6%in the TA group,with the median OS not yet reached.The 1-,3-,5-,and 10-year RFS rates were 79.8%,59.6%,46.2%,and 24.7%in the SR group vs 83.9%,61.5%,47.9%,and 41.2%in the TA group,with median RFS values of 3.95 and 4.63 years,respectively.No significant differences in OS or RFS were observed overall(OS:P=0.244;RFS:P=0.180),but in patients≤60 years,TA led to a higher RFS than SR(P=0.021).Multivariate analysis identified age,tumor differentiation grade,and Child-Pugh classification as independent risk factors for OS,whereas age and differentiation grade were significant risk factors for RFS.CONCLUSION In patients with single sHCC,SR,and TA offered comparable long-term efficacy.However,TA showed superior RFS in patients≤60 years,suggesting that TA may be a reasonable option for younger patients,pending confirmation by prospective studies.

文摘BACKGROUND Colorectal cancer(CRC)frequently metastasizes to the lungs,and image-guided thermal ablation(IGTA)has emerged as a promising treatment for oligometastatic colorectal lung metastases(CRLM).However,high-quality multicenter data remain limited,and the prognostic impact of site-specific extrapulmonary metastases is not well defined.AIM To assess IGTA efficacy in potentially curable oligometastatic CRLM and determine prognostic impacts of extrapulmonary metastatic patterns.METHODS This multicenter real-world study analyzed 336 CRLM patients treated with IGTA from 2014 to 2022.Inclusion criteria included pathologically or clinically confirmed oligometastatic CRC,tumor diameter<50 mm,fewer than 5 metastatic lesions,and≤2 organs involved.Kaplan-Meier and Cox regression methods assessed survival outcomes,including local tumor progression-free survival,progression-free survival(PFS),and overall survival(OS).RESULTS The 3-year cumulative local tumor progression rate was 14.0%.Median PFS and OS were 15.6 and 51 months,respectively,with 3-and 5-year OS rates of 59.5%and 41.0%.Poor survival outcomes were associated with a higher tumor burden(larger size and greater number),carcinoembryonic antigen>20 ng/mL,carbohydrate antigen 19-9>37 U/mL,and extrapulmonary metastases.Patients without extrapulmonary metastasis had 1-,3-,and 5-year PFS rates of 65.4%,31.0%,and 27.3%,respectively,which were longer than those of CRLM patients with liver metastasis[hazard ratio(HR)=1.449,P=0.019]and abdominal cavity metastasis(HR=1.864,P=0.010).The 1-,3-,and 5-year OS rates for patients without extrapulmonary metastasis were 96.4%,71.0%,and 53.0%,respectively,which were significantly longer than those for patients with bone metastasis(HR=4.538,P<0.001),abdominal cavity metastasis(HR=4.813,P<0.001),and pelvic cavity metastasis(HR=3.105,P<0.001).CONCLUSION Metastatic patterns significantly influence PFS and OS,emphasizing the need for careful patient selection.Notably,patients with liver-only extrapulmonary metastasis demonstrate comparatively favorable outcomes,suggesting a distinct biological behavior and better prognosis within this subgroup.
文摘AIM： To evaluate radiofrequency thermal ablation （RTA） for treatment of cystic echinococcosis in animal models （explanted organs）. METHODS： Infected livers and lungs from slaughtered animals, 10 bovine and two ovine, were collected. Cysts were photographed, and their volume, cyst content, germinal layer adhesion status, wall calcification and presence of daughter or adjacent cysts were evaluated by ultrasound. Some cysts were treated with RTA at 150 W, 80℃, 7 min. Temperature was monitored inside and outside the cyst. A second needle was placed inside the cyst for pressure stabilization. After treatment, all cysts were sectioned and examined by histology. Cysts were defined as alive if a preserved germinal layer at histology was evident, and as successfully treated if the germinal layer was necrotic. RESULTS： The subjects of the study were 17 cysts （nine hepatic and eight pulmonary）, who were treated with RTA. Pathology showed 100% success rate in both hepatic （919） and lung cysts （8/8）; immediate volume reduction of at least 65%; layer of host tissue necrosis outside the cyst, with average extension of 0.64 cm for liver and 1.57 cm for lung; and endocyst attached to the pericystium both in hepatic and lung cysts with small and focal de novo endocyst detachment in just 3/9 hepatic cysts. CONCLUSION： RTA appears to be very effective in killing hydatid cysts of explanted liver and lung. Bile duct and bronchial wall necrosis, persistence of endocyst attached to pericystium, should help avoid or greatly decrease in v/vo post-treatment fistula occurrence and consequent overlapping complications that are common after surgery or percutaneous aspiration, injection and reaspiration. In vivo studies are required to confirm and validate this new therapeutic approach.
文摘Percutaneous radiofrequency thermal ablation （RFA） is an effective and safe therapeutic modality in the management of liver malignancies, performed with ultrasound guidance. Potential complications of RFA include liver abscess, ascites, pleural effusion, skin burn, hypoxemia, pneumothorax, subcapsular hematoma, hemoperitoneum, liver failure, tumour seeding, biliary lesions. Here we describe for the first time a case of biliary gastric fistula occurred in a 66-year old man with a Child＇s class A alcoholic liver cirrhosis as a complication of RFA of a large hepatocellular carcinoma lesion in the nl segment. In the light of this case, RFA with injection of saline between the liver and adjacent gastrointestinal tract, as well as laparoscopic RFA, ethanol injection （PEI）, or other techniques such as chemoembolization, appear to be more indicated than percutaneous RFA for large lesions close to the gastrointestinal tract.

文摘Hepatocellular carcinoma(HCC)is one of most common cancers that cause death in the world.Thermal ablation(TA)is an important alternative treatment method for HCC patients who are not appropriate for surgery or liver transplantation.Particularly for small and early HCCs,TA can be considered as the first-line curative treatment.However,local and distant recurrence rates are still high even though the TA equipment and technology develop rapidly.Immunotherapy is a novel systemic treatment method to enhance the anti-tumor immune response of HCC patients,which has the potential to reduce the tumor recurrence and metastasis.The combination of local TA and systemic immunotherapy for HCCs may be an ideal treatment for enhancing the efficacy of TA and controlling the recurrence.Herein we summarize the latest progress in TA,immunotherapy,and their combination for the treatment of patients with HCC and discuss the limitations and future research directions of the combined therapy.
文摘Many studies suggest that combined multimodality treatments including ablative therapies may achieve better outcomes than systemic chemotherapy alone in patients with colorectal liver metastases. Nevertheless, ablative therapies are not yet considered as effective options because their efficacy has never been proved by randomized controlled trials (RCT). However, there are in literature no trials that failed in demonstrating the effectiveness of ablative treatments: what are lacking, are the trials. All the attempts to organize phase III studies on this topic failed as a result of non accrual. Just one prospective RCT comparing radiofrequency ablation combined with systemic chemotherapy vs chemotherapy alone has been published. It was designed as a phase III study, but it was closed early because of slow accrual, and was downscaled to phase II study, with the consequent limits in drawing definite conclusions on the benefit of combined treatment. However, the combination treatment met the primary end point of the study and obtained a significantly higher 3-year progression-free survival than systemic chemotherapy alone. It is very unlikely that ultimate efficacy of ablation treatments will ever be tested again, and the best available evidence points toward a benefit for the combination strategy using ablative treatments and chemotherapy.
文摘The increasing incidence of papillary thyroid microcarcinoma(PTMC)has become a global challenge.Because of its indolent nature,active surveillance(AS)has been proposed as a treatment option in selected PTMC patients to prevent surgery-related complications.However,only a few patients with PTMC receive the AS approach because of the serious psychological burden following the“cancer”diagnosis and the uncertainty of the timing for metastatic dissemination.Ultrasound(US)-guided thermal ablation can bridge the gap in the treatment options of PTMC patients who wish for a minimally invasive management approach.However,it has acquired only marginal attention from the thyroid guideline societies because of concerns regarding incomplete elimination.The recently published guidelines from the European Thyroid Association-Cardiovascular and Interventional Radiological Society of Europe and the American Head Neck Society Endocrine Section-initiated global consensus provide the most definitive evidence and essential foundational experience to address the long-term controversy over USguided thermal ablation for low-risk PTMC patient management and facilitate the responsible global dissemination of minimally invasive strategies.

文摘Thermal ablation(TA),including radiofrequency ablation(RFA)and microwave ablation(MWA),has become the main treatment for early-stage hepatocellular carcinoma(HCC)due to advantages such as safety and minimal invasiveness.However,HCC is prone to local recurrence,with more aggressive malignancies after TA closely related to TA-induced changes in epithelial-mesenchymal transition(EMT)and remodeling of the tumor microenvironment(TME).According to many studies,various components of the TME undergo complex changes after TA,such as the recruitment of innate and adaptive immune cells,the release of tumor-associated antigens(TAAs)and various cytokines,the formation of a hypoxic microenvironment,and tumor angiogenesis.Changes in the TME after TA can partly enhance the anti-tumor immune response;however,this response is weak to kill the tumor completely.Certain components of the TME can induce an immunosuppressive microenvironment through complex interactions,leading to tumor recurrence and progression.How the TME is remodeled after TA and the mechanism by which the TME promotes HCC recurrence and progression are unclear.Thus,in this review,we focused on these issues to highlight potentially effective strategies for reducing and preventing the recurrence and progression of HCC after TA.

文摘Background: With the advances of imaging techniques, the detection rate of rare liver tumor is increased. However, the therapeutic strategies of the rare liver tumors remain limited. Methods: We analyzed twelve pathologically confirmed rare liver tumors in 8 patients. All of the patients underwent ultrasound(US) guided biopsy and subsequent thermal ablation. The tumors were ablated according to the preoperative plans and monitored by real-time US. CT/MRI fused with contrast enhanced US(CEUS) or three-dimensional(3 D) US-CEUS images were used to guide and assess the ablation zone more accurately during thermal ablation. The rate of technical efficacy was assessed based on the contrast-enhance CT/MRI(CECT/MRI) results one month after ablation. Local tumor progression(LTP), recurrence and complications were followed up and recorded. Results: Among these twelve nodules, nine were subject to US-guided thermal ablation, whereas the other three inconspicuous nodules were subject to CEUS-guided thermal ablation. Intra-procedure CT/MRI-CEUS or 3 D US-CEUS fusion imaging assessments demonstrated that the ablation zone sufficiently covered the original tumor, and no immediate supplementary ablation was required. Additionally, no major complications were observed during the follow-up period. The postoperative CECT/MRI confirmed that the technique success rate was 100%. Within the surveillance period of 13 months, no LTP or recurrence was noted. Conclusions: US-guided thermal ablation was feasible and safe for rare liver tumors. The use of fusion imaging technique might make US-guided thermal ablation as effective as surgical resection, and this technique might serve as a potential therapeutic modality for rare liver tumors in the future.

文摘BACKGROUND Debate exists regarding the use of thermal ablation(TA)to treat papillary thyroid carcinoma(PTC).Some studies have recommended TA as a new,efcient and safe technology for PTC.In this article,we report one case of a residual tumor and central lymph node metastasis(CLNM)after TA for PTC.CASE SUMMARY A 63-year-old female underwent bilateral ultrasound(US)-guided radiofrequency ablation for PTC.Three months later,she was diagnosed as thyroid cancer with suspected CLNM by US and contrast-enhanced computed tomography.The subsequent fine-needle aspiration(FNA)biopsies were negative.Due to her strong personal preference,she underwent total thyroidectomy and central lymph node dissection.Local tissue adhesion and a difficult dissection were noted during the operation.The pathology of the frozen sections during the operation was still negative.The final pathology results of paraffin-embedded sections revealed residual tumor cells at the edge of the PTC and CLNM.CONCLUSION TA may lead to a residual tumor in patients with PTC.Follow-up using US and FNA biopsy may not be adequate to evaluate the residual tumor.TA should be carefully considered in PTC treatment.
文摘Even with the advent of laparoscopic techniques for liver tumours,classic resections still represent a major undertaking for numerous liver lesions.The avoidance of surgery using ablative techniques has been the aim for over 20 years.Large volumes can now be rapidly treated with low morbidity with the many technical developments and modifications of the delivery probes.Despite these advances recurrences rates remain high with all of the presently available techniques.The biological and pathophysiological basis underlying may help explain their limitations and are important in understanding where they may be appropriately applied and ways in which they may be improved in the future.
文摘Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Most recipients are women of reproductive age who, as reported in the literature, may be at risk of adverse pregnancy outcomes. This study investigated the risk of abortions, prematurity, stillbirths, and prolonged labor among reproductive-age women following Cryotherapy, Thermal ablation, and Loop Electrosurgical Excision Procedure treatments in Zambia. Methods: This cross-sectional study analyzed records of 8000 women aged 15 - 49 years at the Adult Infectious Disease Control Centre using records between January 2010 and December 2020. Women constituting the treatment group were all respondents treated by cryotherapy, thermal ablation, and LEEP, while the control group were VIA negative women. Women from both groups were invited to answer a phone survey. Data were analyzed using Stata version 16;descriptive analysis estimated the prevalence and obtained the frequency distribution of abortion, prematurity, prolonged labor and fresh stillbiths. Chi-square and Fisher’s exact test established the associations of CIN and APOs at 95% Confidence intervals. Univariate and multivariable binary logistic regression estimated the odds of adverse pregnancy outcomes across the three treatments. Results: Adverse pregnancy outcomes were more prevalent in the treatment group (39.2%) compared to the untreated group (16.9%). Across the two groups, normal outcomes were lower in the treated (42.3% vs 57.7%). The treated group accounted for the majority of abortions (74.5% vs 25.5%) and prolonged labor (72.5% vs 27.5%), while the untreated group accounted for higher proportions of stillbirths (66.7% vs 33.3%) and prematurity (53% vs 47%). Adverse pregnancy outcomes were five and two times more likely in women treated with thermal ablation (aOR = 5.05, 95% CI = 4.01 - 6.36, p Conclusion: Cervical treatment among Zambian women increases the risk of abortion and prolongs labor. Therefore, caution should be taken when administered to those of reproductive age. Vigilant monitoring should be maintained during pregnancy, delivery, and postpartum to improve maternal and neonatal health.
文摘Background: Cervical Intraepithelial neoplasia treatments have become essential interventions to manage cervical lesions. Majority of the recipients of these treatments are women within the reproductive age group, who according to literature may be at risk of adverse pregnancy outcomes. This pilot study is part of a study investigating adverse pregnancy outcomes among women who received Cryotherapy, Thermal ablation and Loop Electrosurgical Excision Procedure compared to the untreated women in Zambia. Materials and Methods: This descriptive study analyzed records of 886 (n = 443 treated and n = 443 untreated) women aged 15 - 49 years. The women were either screened with Visual Inspection with Acetic Acid or treated for Cervical Intraepithelial neoplasia at the Adult Infectious Disease Centre between January 2010 and December 2020. Women meeting the criteria were identified using the Visual Inspection with Acetic Acid screening records and telephone interviews to obtain the adverse pregnancy outcome experienced. Data were analysed using STATA version 16 to determine the prevalence and obtain frequency distribution of outcomes of interest. Univariate and multivariable binary logistic regression estimated odds of adverse pregnancy outcomes across the three treatments. Results: The respondents were aged 15 to 49 years. Adverse pregnancy outcomes were observed to be more prevalent in the treatment group (18.5%) compared to the untreated group (5.4%). Normal pregnancy outcomes were lower in the treated (46.3%;n = 443) than the untreated (53.7%;n = 443). The treated group accounted for the majority of abortions (85.2%), prolonged labour (85.7%) and low birth weight (80%), whereas, the untreated accounted for the majority of still births (72.7%). Women treated with cryotherapy (aOR = 2.43, 95% CI = 1.32 - 4.49, p = 0.004), thermal ablation (aOR = 6.37, 95% CI = 0.99 - 41.2, p = 0.052) and Loop Electrosurgical Excision Procedure (aOR = 9.67, 95% CI = 2.17 - 43.1, p = 0.003) had two-, six- and ten-times higher odds of adverse pregnancy outcomes respectively, relative to women who required no treatment. Conclusion: Adverse pregnancy outcomes are prevalent among women who have received treatment in Zambia. The findings indicate that treating Cervical Intraepithelial Neoplasia has been linked to higher chances of experiencing abortion, delivering low birth weight babies and enduring prolonged labor that may result in a caesarean section delivery. Cervical neoplasia treatments, particularly Loop Electrosurgical Excision Procedure, are associated with significantly increased odds of adverse pregnancy outcomes. It is essential to include information about prior Cervical Intraepithelial neoplasia treatment outcomes in obstetric care.

文摘BACKGROUND Thermal ablation(TA)has been proved to be effective and safe as minimally invasive treatment method for thyroid nodules.However,patients'experience during the procedures and quality of life varies among operators.AIM To explore strategy to improve quality of life and subjective experiences during TA for papillary thyroid carcinoma(PTC)based on thermal field management(TFM).METHODS This retrospective propensity-matched cohort study was conducted in a single center.A total of 490 patients with PTC treated with TA from September 2023 to August 2024 were studied and divided into two groups(TFM group and non-TFM group)according to treatment strategies.Propensity score matching(PSM)was used to control for confounding factors.Complications,side effect and com-plaints of patients were compared between the two groups.RESULTS A total of 113 patients(41.7±10.6;31 men,82 women)were assigned to the TFM group,and 377 patients(mean age,41.1±10.7 year;116 men,261 women)were assigned to the non-TFM group.After PSM,a total of 108 patients were included in the TFM group,and 216 patients were included in the non-TFM group.The median follow-up was 10 months(range from 4-15 months).The incidence of voice change in the TFM group was significantly lower than that in the non-TFM group(0.9%vs 6.5%;P=0.049).Although there was no statistically significant difference in rate of pain between the two groups,the proportion of complaining of pain in the TFM group was numerically lower than that in the non-TFM group(3.7%vs 9.7%,P=0.090).CONCLUSION TFM,as a novel procedural optimization technique,can effectively improve quality of life and subjective expe-riences of patients during TA for PTC.
文摘Thermal ablation has become an established minimally invasive alternative to surgery for papillary thyroid carcinoma,particularly in low-risk patients seeking effective treatment with reduced morbidity.While clinical outcomes are favorable,wide variability in complication rates and patient-reported experiences persists across centers and operators,emphasizing the need for strategies that standardize safety and enhance quality of life.Cai et al now introduce thermal field management(TFM),a thoughtful approach that reframes thermal ablation from a purely technical procedure into a precision-guided,patient-centered intervention.By deliberately confining the ablation zone to protect surrounding tissues,TFM addresses complications such as voice change and pain,issues often overlooked in the pursuit of technical success.Their findings,showing reduced complications and improved patient comfort,highlight the value of integrating patient-reported outcomes into routine ablation practice.This places TFM within the broader trajectory of interventional oncology,where precision and patientcenteredness are becoming central goals.If validated in multicenter prospective studies,TFM could extend beyond thyroid cancer and inform the evolution of safer,standardized ablative therapies across multiple organ systems.

文摘Objective:Non-lactating mastitis is a group of benign,non-specific inflammatory diseases of unknown etiology that occur during the non-lactating period in women.Treatment is mainly based on drugs and surgery,but these two treatments have certain limitations and cannot meet the individual needs of patients.In recent years,thermal ablation technology has made significant progress in treating and researching breast diseases,especially in the exploratory thermal ablation treatment of non-lactating mastitis,which has achieved certain efficacy,but it is in the initial stage of development.To standardize the development and clinical practice,we have formu-lated the consensus.Methods:Seventy-three multidisciplinary experts from 48 tertiary-level hospitals carried out this work.The consensus formulation method(Delphi technique)was used to discuss and vote on the latest research advances,and formulated in light of the actual clinical situation in China.Results:Multidisciplinary experts discussed the indications and contraindications of non-lactating mastitis thermal ablation therapy,standardization of intraoperative operation,management of postoperative complica-tions,evaluation of therapeutic efficacy,and follow-up,and finally formed this consensus.Conclusions:Thermal ablation provides a new minimally invasive treatment option for non-lactating mastitis,but it is still in the process of clinical exploration,and prospective high-quality clinical studies with large samples are needed in the future.This consensus was developed to provide a reference for clinicians who are currently practicing this technique,but due to the limited number of cases and units,it will need to be revised and improved in future clinical practice.
