Methods: A total of 314 patients with invasive breast cancer from Baoding First Central Hospital between January 2021 and December 2022, and 31 patients with benign breast diseases (including mastitis, breast fibroadenoma, breast adenosis, adenoma of the breast, benign phyllodes tumor of the breast, and intraductal papilloma) were randomly selected as the control group. The levels of CEA, AFP, CA199, CA125, CA153, CYFRA21, CA724, and NSE were measured using electrochemiluminescence. Results: The serum concentrations of CEA, CA153, and CYFRA21 showed significant statistical differences between the invasive breast cancer group and the benign breast disease group (P < 0.01). ROC curve analysis revealed that CA153 had the highest sensitivity for diagnosing invasive breast cancer, while CEA had the highest specificity, at 84.4% and 77.4%, respectively. When multiple tumor markers were used for the diagnosis of invasive breast cancer, the combination of CEA and CA153 showed the highest specificity at 90.3%, while the combination of CEA and CYFRA21 had the highest sensitivity at 88.2%. The combined detection of CEA, CYFRA21, and CA153 had the largest area under the curve (AUC) on the ROC curve, at 0.802, indicating that the combination of these three markers provided the best diagnostic performance for invasive breast cancer. Conclusion: CEA, CA153, and CYFRA21 can be used for the diagnosis of invasive breast cancer, and the combined detection of these three markers offers the best diagnostic efficacy for invasive breast cancer.展开更多

文摘Objective:To enhance the reading skills of clinical pathology residents,it is essential to establish a well-structured electronic pathology reading library.Methods:In accordance with the Resident Standardization Training Content and Standards(2022 Edition),clinical pathology residents are required to master pathological diagnoses across 11 systems:skin,head and neck,mediastinum and respiratory,digestive,urinary and male reproductive,female reproductive and breast,lymphatic and hematopoietic,bone and soft tissue,cardiovascular,central nervous,and endocrine diseases.Senior pathologists specializing in each subspecialty selected classic pathological slides,which were systematically scanned and compiled into an electronic pathology library.Results:A questionnaire survey was conducted to gather feedback on the electronic pathology reading library.Residents generally found it to be convenient,efficient,and conducive to learning.Conclusion:Training in clinical pathology diagnosis is a core component of standardized resident training.The electronic pathology reading library has been well-received and recognized by resident doctors.However,further efforts are needed to explore diverse teaching methods that align with modern educational approaches,ultimately contributing to the development of highly skilled resident doctors.
文摘BACKGROUND Endobronchial metastases(EBMs)are tumours that metastasise from a malignant tumour outside the lungs to the central and subsegmental bronchi,and are visible under a bronchofibrescope.Most EBMs are formed by direct invasion or metastasis of intrathoracic malignant tumours,such as lung cancer,oesophageal cancer or mediastinum tumours.Renal cell carcinoma(RCC),accounting for 2%to 3%of all tumours,is a common malignant tumour of the urinary system.Renal clear cell carcinoma(RCCC)constitutes the predominant pathological subtype of RCC,comprising approximately 70%to 80%of all RCC cases.RCCC can spread and metastasise through arterial,venous and lymphatic circulation to almost all organs of the body.Moreover,lung,bone,liver,brain and local recurrence are the most common metastatic neoplasms of RCCC.However,EBM from RCCC has a low complication rate and is often misdiagnosed as primary lung cancer.CASE SUMMARY A 71-year-old male patient who had undergone radical left nephrectomy 7 years prior due to RCCC was referred to our hospital due to a 1-mo history of productive cough.The results of an enhanced chest CT scan indicated the presence of a soft tissue nodule in the upper lobe of the left lung,and flexible bronchoscopy revealed a hypervascular lesion in the bronchus of the left lung's superior lobe.Therefore,the patient underwent thoracoscopic left superior lobe wedge resection,and pathology confirmed EBM from the RCCC.CONCLUSION EBM from RCCC has a low incidence and no characteristic clinical manifestations in the early stage.If a bronchial tumour is found in a patient with RCCC,the possibility of bronchial metastatic cancer should be considered.
文摘BACKGROUND Surgical resection remains the primary treatment for hepatic malignancies,and intraoperative bleeding is associated with a significantly increased risk of death.Therefore,accurate prediction of intraoperative bleeding risk in patients with hepatic malignancies is essential to preventing bleeding in advance and providing safer and more effective treatment.AIM To develop a predictive model for intraoperative bleeding in primary hepatic malignancy patients for improving surgical planning and outcomes.METHODS The retrospective analysis enrolled patients diagnosed with primary hepatic malignancies who underwent surgery at the Hepatobiliary Surgery Department of the Fourth Hospital of Hebei Medical University between 2010 and 2020.Logistic regression analysis was performed to identify potential risk factors for intraoperative bleeding.A prediction model was developed using Python programming language,and its accuracy was evaluated using receiver operating characteristic(ROC)curve analysis.RESULTS Among 406 primary liver cancer patients,16.0%(65/406)suffered massive intraoperative bleeding.Logistic regression analysis identified four variables as associated with intraoperative bleeding in these patients:ascites[odds ratio(OR):22.839;P<0.05],history of alcohol consumption(OR:2.950;P<0.015),TNM staging(OR:2.441;P<0.001),and albumin-bilirubin score(OR:2.361;P<0.001).These variables were used to construct the prediction model.The 406 patients were randomly assigned to a training set(70%)and a prediction set(30%).The area under the ROC curve values for the model’s ability to predict intraoperative bleeding were 0.844 in the training set and 0.80 in the prediction set.CONCLUSION The developed and validated model predicts significant intraoperative blood loss in primary hepatic malignancies using four preoperative clinical factors by considering four preoperative clinical factors:ascites,history of alcohol consumption,TNM staging,and albumin-bilirubin score.Consequently,this model holds promise for enhancing individualised surgical planning.

文摘Objective: To explore the diagnostic value of serum tumor markers CEA, AFP, CA199, CA125, CA153, CYFRA21, CA724, and NSE in invasive breast cancer. Methods: A total of 314 patients with invasive breast cancer from Baoding First Central Hospital between January 2021 and December 2022, and 31 patients with benign breast diseases (including mastitis, breast fibroadenoma, breast adenosis, adenoma of the breast, benign phyllodes tumor of the breast, and intraductal papilloma) were randomly selected as the control group. The levels of CEA, AFP, CA199, CA125, CA153, CYFRA21, CA724, and NSE were measured using electrochemiluminescence. Results: The serum concentrations of CEA, CA153, and CYFRA21 showed significant statistical differences between the invasive breast cancer group and the benign breast disease group (P < 0.01). ROC curve analysis revealed that CA153 had the highest sensitivity for diagnosing invasive breast cancer, while CEA had the highest specificity, at 84.4% and 77.4%, respectively. When multiple tumor markers were used for the diagnosis of invasive breast cancer, the combination of CEA and CA153 showed the highest specificity at 90.3%, while the combination of CEA and CYFRA21 had the highest sensitivity at 88.2%. The combined detection of CEA, CYFRA21, and CA153 had the largest area under the curve (AUC) on the ROC curve, at 0.802, indicating that the combination of these three markers provided the best diagnostic performance for invasive breast cancer. Conclusion: CEA, CA153, and CYFRA21 can be used for the diagnosis of invasive breast cancer, and the combined detection of these three markers offers the best diagnostic efficacy for invasive breast cancer.

文摘Breast cancer metastasis is a major cause of treatment failure and patient mortality. Mouse tumor models largely replicate the pathophysiological processes of human tumors. Establishing mouse models of breast cancer metastasis helps to elucidate metastatic mechanisms, and in vivo imaging techniques enable dynamic monitoring of tumor cell metastasis in animals. This paper summarizes the mechanisms of breast cancer metastasis, the development, and application of various mouse breast cancer distant metastasis models over the past decade, and evaluates the characteristics and efficacy of each model to provide references for future experimental studies.
文摘AIM:To provide a detailed description of the natural history of persistent subretinal fluid(SRF)after successful repair of rhegmatogenous retinal detachment(RRD)and its association with visual outcome.METHODS:This was a prospective long-term follow-up for eyes undergoing scleral buckling(SB)surgery for maculaoff RRD.Examinations were carried out preoperatively and postoperatively at 1,3,6,9 and 12 mo,until persistent SRF had completely resolved.One month postoperatively,optical coherence tomography(OCT)was used to classify SRF into three patterns:bleb-like loculated(BL),shallow-diffused(SD),and multiple blebs(MB).Serial OCT imaging was used to evaluate morphological changes in SRF until its complete disappearance.Patients were divided into two groups depending on the presence or absence of persistent SRF.RESULTS:A total of 59 patients(59 eyes)were included.There were no statistical differences between two groups at baseline,except for the proportion of patients with high myopia and a younger age.One month after surgery,OCT detected persistent SRF in 49 eyes(83.1%).The 3 morphological patterns of SRF were observed in 27 eyes(55.1%)with BL,13 eyes(26.5%)with SD,and 9 eyes(18.4%)with MB.The mean time for complete absorption differed significantly across the three SRF patterns(F=8.097,P=0.001),which was 8.8±6.1,20.1±12.1,and 16.7±10.2 mo in BL,SD,and MB,respectively.In 9 of the 13 eyes with SD,the pattern transformed into MB type.In cases involving MB,the size and number of blebs decreased gradually until they had been completely absorbed.Eyes with persistent SRF were more likely to demonstrate disruption of the ellipsoid zone(49.0%vs 10%,P=0.034).The final best-corrected visual acuity of two groups was 0.37±0.11(with SRF)vs 0.34±0.12(without SRF)logMAR(P=0.499),respectively.CONCLUSION:High preoperative myopia and younger age are associated with persistent SRF.BL is the most commonly observed pattern with the shortest duration and gradually disappeared.Most cases involving SD SRF transform into MB type during resolution.The size and number of the MBs decrease gradually until they were completely absorbed.The absence of persistent SRF may contribute to slow visual recovery in the short-term but does not influence the final visual outcome.
文摘AIM:To explore the protective effects of amino-guanidine(AG) on retinal apoptosis in mice with oxygeninduced retinopathy(OIR).·METHODS:A total of 80 C57BL/6J mice,aged 7 days,were randomly divided into four groups:normal,high oxygen,high oxygen saline and high oxygen treated with AG.In the normal group,mice were housed in normoxic conditions from postnatal day P7 to P17.Mice in the other 3 groups were placed under hyperoxic conditions(75 ±2% O2) in an oxygen-regulated chamber for 5 days and subsequently placed in normoxic conditions for 5days.Mice in the AG group were treated once daily,from P12 to P17,with AG hemisulfate(100mg/kg body weight,intraperitoneally) dissolved in physiological saline.An equivalent amount of 0.9% physiological saline was administered,as above,to mice in the high oxygen saline group.Ten mice were randomly selected from each group on P14 and on P17,euthanized and the retinas examined.Apoptotic cells in the retina were detected using the terminal-deoxynucleoitidyl transferase mediated nick end labeling(TUNEL) method.The expression of nitric oxide synthase(iNOS) in the retina was detected by immunohistochemistry and changes in rod cells were observed using electron microscopy.·RESULTS:TUNEL-positive cells and iNOS immunoreactive neurons were present in the inner nuclear and ganglion cell retinal layers of mice in the high oxygen group.The number of TUNEL-positive cells was significantly greater in the high oxygen group compared with the normal group(t =-20.81,P14d【0.05;t =-15.05,P17d【0.05).However,the number of TUNEL-positive cells in the AG treatment group was significantly lower(t =-13.21,P14d【0.05;t =-6.61,P17d【0.05) compared with thehigh oxygen group.The expression of iNOS was significantly higher in the high oxygen group compared with the normal group(t =-21.95,P14d【0.05;t =-17.30,P17d【0.05).However,the expression of iNOS in the AG treatment group was significantly lower(t =-12.17,P14d【0.05;t =-10.30,P17d【0.05) compared with the high oxygen group.The outer segments of the rods were disorganized and short in the high oxygen group.Rod morphology appeared to be slightly improved in the AG group.·CONCLUSION:AG may protect retinal neurons in OIR by inhibiting apoptosis.The mechanism may be related to iNOS.

文摘BACKGROUND Primary retroperitoneal liposarcoma(PRPLS)is a rare soft tissue tumor with nonspecific clinical symptoms;it has different computed tomography(CT)image features according to pathological types.Some patients with a single tumor have been previously reported in the literature.We present an exceptional case of a PRPLS patient with multiple large tumors exhibiting different patterns of appearance on CT and confirmed as atypical lipomatous tumor/welldifferentiated liposarcoma by postoperative pathology.CASE SUMMARY A 64-year-old man presented with abdominal distension for 1 year.The patient was diagnosed with PRPLS based on physical examination,laparotomy,ultrasonography,CT scan,and surgery.Both of the tumors were completely resected through surgery and confirmed as atypical lipomatous tumor/welldifferentiated liposarcoma by postoperative pathology.The postoperative course was uneventful without recurrence or metastasis,as demonstrated by abdominalpelvic CT during an 18 mo follow-up.CONCLUSION Multiple large Well-differentiated liposarcomas with different patterns of appearance on CT image can occur simultaneously in the same patient,to which more attention should be paid to make an effective differential diagnosis.
文摘BACKGROUND Collision carcinoma is a rare histological pattern,and includes two or more different types of tumors coexisting in the same organ as one neoplasm.Different to the combined type,the two adjacent tumors of collision carcinoma are histologically distinct.Collision carcinoma may occur from any origin or organ,including the cecum,liver,cervix,thyroid,stomach,kidney,and esophagus.In the rectum,adenocarcinoma is the most common pathological type,the combined type is rare,and collision tumors are even rarer.To date,only a limited number of collision carcinoma cases originating from the rectum have been reported.Due to the scarcity of rectal collision carcinoma,more cases need to be reported to fully understand the clinico-pathological features and biological behavior of the tumor.CASE SUMMARY Here we report a 40-year-old female who presented with the chief complaints of persistent changes in bowel habits and hematochezia for 10 d.She underwent Miles'operation which revealed a collision carcinoma of the rectum,showing a“side by side”pattern,composed of a high grade neuroendocrine carcinoma,(small cell carcinoma)and moderately differentiated adenocarcinoma,based on its clinico-pathological features and biological behavior.The patient remained disease-free at 12 mo follow-up.We also focused on the related literature and expert opinion.CONCLUSION Collision carcinoma is a rare tumor with ambiguous biological behavior.Greater attention should be paid to its clinico-pathologic diagnosis.Regular and adequate follow-up is essential to help rule out metastasis and assess the prognosis.
文摘Objective:To investigate the expression and clinical significance of hypoxia inducible factors HIF-1a,Gli-1 and MMP9 in breast cancer.Methods:Eighty patients with invasive ductal carcinoma of the breast and 40 normal tissues adjacent to cancer were selected.Immunohistochemical methods were used to detect the expression of HIF-1a,Gli-1 and MMP9 in breast cancer and normal tissues adjacent to cancer,and their re1ationship with clinicopathological features of breast cancer and prognosis was explored.Results:The positive rates of HIF-1a,Gli-1 and MMP9 in breast cancer tissues were significantly higher than those in normal breast tissues.HIF-1a,Gli-1 and MMP9 expressions are positively corre1ated in breast cancer.Conclusion:HIF-1a,Gli-1 and MMP9 proteins are involved in the pathogenesis of breast cancer.
