The chief surgical problem to face after primary treatment is recurrent ovarian cancer. Of far more marginal concern are the second-look surgical procedures or the palliative efforts intended to resolve the patient's symptoms with no curative intent. The role of surgery in recurrent ovarian cancer remains poorly defi ned. Current data, albeit from non-randomized studies, nevertheless clearly support surgical cytoreduction in selected patients, a rarely curative expedient that invariably yields a marked survival advantage over chemotherapy alone. Despite these fi ndings, some consider it too early to adopt secondary cytoreduction as the standard care for patients with recurrent ovarian cancer and a randomized study is needed. Two ongoing randomized trials(Arbeitsgemeinschaft Gynkologische Onkologie-Desktop Ⅲ and Gynecologic Oncology Group 213) intend to verify the role of secondary cytoreduction for platinum-sensitive ovarian cancer compared with chemotherapy considered as standard care for these patients. We await the results of these two trials for a defi nitive answer to the matter.展开更多

The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery(CRS) + hyperthermic intraperitoneal chemotherapy(HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases Ⅰ, Ⅱ and Ⅲ clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.展开更多

Systemic chemotherapy including targeted agents has not been found to significantly increase the survival in GCPC. Since recurrent gastric cancer remains confined to the abdominal cavity in many patients, regional therapies like aggressive cytoreductive surgery( CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) have been investigated for GCPC. HIPEC has been used for three indications in GC- as an adjuvant therapy after a curative surgery, HIPEC has been shown to improve survival and reduce peritoneal recurrences in many randomised trials in Asian countries; as a definitive treatment in established PC, HIPEC along with CRS is the only therapeutic modality that has resulted in longterm survival in select groups of patients; as a palliative treatment in advanced PC with intractable ascites, HIPEC has been shown to control ascites and reduce the need for frequent paracentesis. While the results of randomised trials of adjuvant HIPEC from western centres are awaited, the role of HIPEC in the treatment of GCPC is still evolving and needs larger studies before it is accepted as a standard of care.展开更多

Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 too. With the establishment of several phase Ⅱ studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase Ⅲ studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.展开更多

Since the birth of a new approach, cytoreductive surgery with peritonectomy procedures together with hyperthermic intraperitoneal chemotherapy and/or early postoperative intraperitoneal chemotherapy to treat peritoneal carcinomatosis, many research groups contributed with promising results using this procedure being up to date this strategy the only one that has shown curative benefits on colorectal peritoneal carcinomatosis achieving reported overall survival rates up to 64 mo and fiveyear survival rates up to 51%. The aim of this paper is to expose an updated overview of the therapeutic possibilities of these procedures in colorectal peritoneal metastases in the same way that our Unit of Oncologic Surgery has performed since 1997 with more than four hundred procedures.展开更多

But its role in assessing the primary optimal debulking（OD） of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma.Methods： We reviewed the records of 90 patients with advanced ovarian, tubal or peritoneal carcinoma who underwent primary cytoreduction at the Department of Obstetrics and Gynecology of Peking University People＇s Hospital between November 2005 and October 2010. Preoperative serum HE4 and CA125 levels were detected with EIA kit. A receiver operating characteristic（ROC） curve was used to determine the most useful HE4 cut-off value. Logistic regression analysis was performed to identify significant preoperative clinical characteristics to predict optimal primary cytoreduction.Results： OD was achieved in 47.7%（43/48） of patients. The median preoperative HE4 level for patients with OD vs. suboptimal debulking was 423 and 820 pmol/L, respectively（P〈0.001）. The areas under the ROC curve for HE4 and CA125 were 0.716 and 0.599, respectively（P=0.080）. The most useful HE4 cut-off value was 473 pmol/L. Suboptimal cytoreduction was obtained in 66.7%（38/57） of cases with HE4 ≥473 pmol/L compared with only 27.3%（9/33） of cases with HE4 〈473 pmol/L. At this threshold, the sensitivity, specificity, positive predictive value（PPV） and negative predictive value（NPV） for diagnosing suboptimal debulking were 81%, 56%, 67%, and 73%, respectively. Logistic regression analysis showed that the patients with HE4 ≥473 pmol/L were less likely to achieve OD（odds ratio =5.044, P=0.002）.Conclusions： Preoperative serum HE4 may be helpful to predict whether optimal cytoreductive surgery could be obtained or whether extended cytoreduction would be needed by an interdisciplinary team.展开更多

However, the safety and benefit of cytoreduction in metastatic prostate cancer （mPCa） has not been proven. Therefore, we evaluated the incidence of complications following CRP in men newly diagnosed with mPCa. A total of 68 patients who underwent CRP from 2006 to 2014 at four tertiary surgical centers were compared to 598 men who underwent radical prostatectomy for clinically localized prostate cancer （PCa）. Urinary incontinence was defined as the use of any pad. CRP had longer operative times （200 min vs 140 min, P 〈 0.0001） and higher estimated blood loss （250 ml vs 125 ml, P 〈 0.0001） compared to the control group. However, both overall （8.82% vs 5.85%） and major complication rates （4.41% vs 2.17%） were comparable between the two groups. Importantly, urinary incontinence rate at 1-year after surgery was significantly higher in the CRP group （57.4% vs 90.8%, P 〈 0.0001）. Univariate logistic analysis showed that the estimated blood loss was the only independent predictor of perioperative complications both in the unadjusted model （OR： 1.18; 95% Ch 1.02-1.37; P= 0.025） and surgery type-adjusted model （OR： 1.17; 95% Ch 1.01-1.36; P= 0.034）. In conclusion, CRP is more challenging than radical prostatectomy and associated with a notably higher incidence of urinary incontinence. Nevertheless, CRP is a technically feasible and safe surgery for selecting PCa patients who present with node-positive or bony metastasis when performed by experienced surgeons. A prospective, multi-institutional clinical trial is currently underway to verify this concept.展开更多

The combination of aggressive cytoreductive surgery (CRS), involving peritonectomy procedures and multivisceral resections, with intra-operative hyperthermic intra-peritoneal chemotherapy (HIPEC) and/or early postoperative intra-peritoneal chemotherapy (EPIC) to treat the microscopic residual tumor is a new concept. In recent years, promising results have been reported for peritoneal mesothelioma and carcinomatosis of gastrointestinal and gynaecologic origin treated by this combined protocol. However, CRS with HIPEC and/or EPIC is a complex procedure associated with high rates of potentially life-threatening complications. Furthermore, disease progression following comprehensive treatment is not uncommon and represents a relevant cause of treatment failure. The present paper reviews the available information on early postoperative management and long-term follow-up in patients treated with CRS and intraperitoneal chemotherapy. The peculiar clinical and biological alterations that can be expected during an uncomplicated postoperative course, as compared to standard digestive surgery, are discussed. Early recognition and appropriate management of the most common adverse events are addressed, in order to minimize the impact of treatment-related morbidity on survival and quality of life results. Since re-operative surgery with additional HIPEC, has proven to be useful in selected patients with recurrent disease, long-term surveillance aiming at early detection of postoperative disease progression has become a relevant issue. Current results on follow-up investigations are presented.展开更多

In addition to reviewing the natural history of gastric cancer with peritoneal carcinomatosis, this mini-review examines literature on the efficacy of CRS and HIPEC as compared to chemotherapy and surgical options. Both randomized and nonrandomized studies were summarized with the emphasis focused on overall survival. In summary, CRS and HIPEC are indeed a promising treatment option for gastric cancer with peritoneal carcinomatosis and large randomized clinical trials are warranted.展开更多

We describe a case of...There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.展开更多

文摘BACKGROUND Major postoperative complications have proved to be an independent adverse prognostic factor for long-term survival in patients undergoing cytoreductive surgery(CRS)with or without hyperthermic intraperitoneal chemotherapy(HIPEC).C-reactive protein(CRP)is an inflammatory marker that is reportedly a useful tool for the early prediction of postoperative complications,as is the neutrophil-to-lymphocyte ratio(NLR).In patients with peritoneal carcinomatosis,postoperative CRP levels on days 2 to 4 are predictors of early complications after CRS plus HIPEC.AIM To determine the usefulness of CRP and NLR for the early detection of overall postoperative infections(OPIs)after CRS+/-HIPEC.METHODS Patients treated on a peritoneal carcinomatosis program at a tertiary care hospital,in whom complete or optimal cytoreduction was achieved,were analyzed retrospectively.A total of 111 patients were included in this study.CRP and NRL evaluated.RESULTS Of the 111 patients included,19 presented OPI and 8 intra-abdominal infections.Patients with infections had a higher number of digestive anastomoses than those without(1 vs 0.5,P=0.053 and 1.2 vs 0.6,P=0.049)and longer length of stay(19 vs 14.9 days,P=0.022 and 22.3 vs 15.1 days,P=0.006).CRP values above 118 mg/L on POD3 yielded a sensitivity of 66.7%and a specificity of 74.2%to detect OPI.No differences in NLR values were observed.Patients with immunonutrition intake had higher CRP levels regardless of whether they presented OPI.Subsequently,on POD3 and POD4,patients with OPI presented with higher levels of CRP than patients without infection,regardless of the immunonutrition intake.CONCLUSION CRP levels are useful to detect early OPI in patients with peritoneal carcinomatosis undergoing CRS.A cut-off value of 118 mg/L on POD3 yields the best sensitivity and specificity.

Current data, albeit from non-randomized studies, nevertheless clearly support surgical cytoreduction in selected patients, a rarely curative expedient that invariably yields a marked survival advantage over chemotherapy alone. Despite these fi ndings, some consider it too early to adopt secondary cytoreduction as the standard care for patients with recurrent ovarian cancer and a randomized study is needed. Two ongoing randomized trials(Arbeitsgemeinschaft Gynkologische Onkologie-Desktop Ⅲ and Gynecologic Oncology Group 213) intend to verify the role of secondary cytoreduction for platinum-sensitive ovarian cancer compared with chemotherapy considered as standard care for these patients. We await the results of these two trials for a defi nitive answer to the matter.

文摘Locoregional spread of abdominopelvic malignant tumors frequently results in peritoneal carcinomatosis(PC). The prognosis of PC patients treated by conventional systemic chemotherapy is poor, with a median survival of < 6 mo. However, over the past three decades, an integrated treatment strategy of cytoreductive surgery(CRS) + hyperthermic intraperitoneal chemotherapy(HIPEC) has been developed by the pioneering oncologists, with proved efficacy and safety in selected patients. Supported by several lines of clinical evidence from phases Ⅰ, Ⅱ and Ⅲ clinical trials, CRS + HIPEC has been regarded as the standard treatment for selected patients with PC in many established cancer centers worldwide. In China, an expert consensus on CRS + HIPEC has been reached by the leading surgical and medical oncologists, under the framework of the China Anti-Cancer Association. This expert consensus has summarized the progress in PC clinical studies and systematically evaluated the CRS + HIPEC procedures in China as well as across the world, so as to lay the foundation for formulating PC treatment guidelines specific to the national conditions of China.
文摘Gastric cancer associated peritoneal carcinomatosis(GCPC) has a poor prognosis with a median survival of less than one year. Systemic chemotherapy including targeted agents has not been found to significantly increase the survival in GCPC. Since recurrent gastric cancer remains confined to the abdominal cavity in many patients, regional therapies like aggressive cytoreductive surgery( CRS) and hyperthermic intraperitoneal chemotherapy(HIPEC) have been investigated for GCPC. HIPEC has been used for three indications in GC- as an adjuvant therapy after a curative surgery, HIPEC has been shown to improve survival and reduce peritoneal recurrences in many randomised trials in Asian countries; as a definitive treatment in established PC, HIPEC along with CRS is the only therapeutic modality that has resulted in longterm survival in select groups of patients; as a palliative treatment in advanced PC with intractable ascites, HIPEC has been shown to control ascites and reduce the need for frequent paracentesis. While the results of randomised trials of adjuvant HIPEC from western centres are awaited, the role of HIPEC in the treatment of GCPC is still evolving and needs larger studies before it is accepted as a standard of care.

文摘This article is to offer a concise review on the use of cytoreductive surgery （CRS） plus intraperitoneal hyperthermic chemotherapy （IPHC） for the treatment of peritoneal carcinomatosis （PC）. Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 too. With the establishment of several phase Ⅱ studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase Ⅲ studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.
文摘Colorectal peritoneal carcinomatosis was considered a terminal condition with a merely palliative treatment that included only supportive care, palliative surgery and the best systemic chemotherapy. Since the birth of a new approach, cytoreductive surgery with peritonectomy procedures together with hyperthermic intraperitoneal chemotherapy and/or early postoperative intraperitoneal chemotherapy to treat peritoneal carcinomatosis, many research groups contributed with promising results using this procedure being up to date this strategy the only one that has shown curative benefits on colorectal peritoneal carcinomatosis achieving reported overall survival rates up to 64 mo and fiveyear survival rates up to 51%. The aim of this paper is to expose an updated overview of the therapeutic possibilities of these procedures in colorectal peritoneal metastases in the same way that our Unit of Oncologic Surgery has performed since 1997 with more than four hundred procedures.

文摘Objective： Human epididymis protein 4（HE4） is a promising biomarker of epithelial ovarian cancer（EOC）. But its role in assessing the primary optimal debulking（OD） of EOC remains unknown. The purpose of this study is to elucidate the ability of preoperative HE4 in predicting the primary cytoreductive outcomes in advanced EOC, tubal or peritoneal carcinoma.Methods： We reviewed the records of 90 patients with advanced ovarian, tubal or peritoneal carcinoma who underwent primary cytoreduction at the Department of Obstetrics and Gynecology of Peking University People＇s Hospital between November 2005 and October 2010. Preoperative serum HE4 and CA125 levels were detected with EIA kit. A receiver operating characteristic（ROC） curve was used to determine the most useful HE4 cut-off value. Logistic regression analysis was performed to identify significant preoperative clinical characteristics to predict optimal primary cytoreduction.Results： OD was achieved in 47.7%（43/48） of patients. The median preoperative HE4 level for patients with OD vs. suboptimal debulking was 423 and 820 pmol/L, respectively（P〈0.001）. The areas under the ROC curve for HE4 and CA125 were 0.716 and 0.599, respectively（P=0.080）. The most useful HE4 cut-off value was 473 pmol/L. Suboptimal cytoreduction was obtained in 66.7%（38/57） of cases with HE4 ≥473 pmol/L compared with only 27.3%（9/33） of cases with HE4 〈473 pmol/L. At this threshold, the sensitivity, specificity, positive predictive value（PPV） and negative predictive value（NPV） for diagnosing suboptimal debulking were 81%, 56%, 67%, and 73%, respectively. Logistic regression analysis showed that the patients with HE4 ≥473 pmol/L were less likely to achieve OD（odds ratio =5.044, P=0.002）.Conclusions： Preoperative serum HE4 may be helpful to predict whether optimal cytoreductive surgery could be obtained or whether extended cytoreduction would be needed by an interdisciplinary team.
文摘Emerging evidence has suggested that cytoreductive prostatectomy （CRP） allows superior oncologic control when compared to current standard of care androgen deprivation therapy alone. However, the safety and benefit of cytoreduction in metastatic prostate cancer （mPCa） has not been proven. Therefore, we evaluated the incidence of complications following CRP in men newly diagnosed with mPCa. A total of 68 patients who underwent CRP from 2006 to 2014 at four tertiary surgical centers were compared to 598 men who underwent radical prostatectomy for clinically localized prostate cancer （PCa）. Urinary incontinence was defined as the use of any pad. CRP had longer operative times （200 min vs 140 min, P 〈 0.0001） and higher estimated blood loss （250 ml vs 125 ml, P 〈 0.0001） compared to the control group. However, both overall （8.82% vs 5.85%） and major complication rates （4.41% vs 2.17%） were comparable between the two groups. Importantly, urinary incontinence rate at 1-year after surgery was significantly higher in the CRP group （57.4% vs 90.8%, P 〈 0.0001）. Univariate logistic analysis showed that the estimated blood loss was the only independent predictor of perioperative complications both in the unadjusted model （OR： 1.18; 95% Ch 1.02-1.37; P= 0.025） and surgery type-adjusted model （OR： 1.17; 95% Ch 1.01-1.36; P= 0.034）. In conclusion, CRP is more challenging than radical prostatectomy and associated with a notably higher incidence of urinary incontinence. Nevertheless, CRP is a technically feasible and safe surgery for selecting PCa patients who present with node-positive or bony metastasis when performed by experienced surgeons. A prospective, multi-institutional clinical trial is currently underway to verify this concept.

文摘AIM: To systematically review the available evidence regarding cytoreductive surgery (CRS) and intraperitoneal chemotherapy (IPC) for colorectal peritoneal metastases (CPM).
文摘Peritoneal surface malignancies have been traditionally regarded as end-stage conditions amenable to merely palliative options. The combination of aggressive cytoreductive surgery (CRS), involving peritonectomy procedures and multivisceral resections, with intra-operative hyperthermic intra-peritoneal chemotherapy (HIPEC) and/or early postoperative intra-peritoneal chemotherapy (EPIC) to treat the microscopic residual tumor is a new concept. In recent years, promising results have been reported for peritoneal mesothelioma and carcinomatosis of gastrointestinal and gynaecologic origin treated by this combined protocol. However, CRS with HIPEC and/or EPIC is a complex procedure associated with high rates of potentially life-threatening complications. Furthermore, disease progression following comprehensive treatment is not uncommon and represents a relevant cause of treatment failure. The present paper reviews the available information on early postoperative management and long-term follow-up in patients treated with CRS and intraperitoneal chemotherapy. The peculiar clinical and biological alterations that can be expected during an uncomplicated postoperative course, as compared to standard digestive surgery, are discussed. Early recognition and appropriate management of the most common adverse events are addressed, in order to minimize the impact of treatment-related morbidity on survival and quality of life results. Since re-operative surgery with additional HIPEC, has proven to be useful in selected patients with recurrent disease, long-term surveillance aiming at early detection of postoperative disease progression has become a relevant issue. Current results on follow-up investigations are presented.
文摘Although gastric cancer with peritoneal carcinomatosis is associated with poor prognosis and is generally treated with palliative systemic therapy, recent studies have shown that cytoreductive surgery（CRS） and hyperthermic intraperitoneal chemotherapy（HIPEC） may prove to be an efficacious treatment option. In addition to reviewing the natural history of gastric cancer with peritoneal carcinomatosis, this mini-review examines literature on the efficacy of CRS and HIPEC as compared to chemotherapy and surgical options. Both randomized and nonrandomized studies were summarized with the emphasis focused on overall survival. In summary, CRS and HIPEC are indeed a promising treatment option for gastric cancer with peritoneal carcinomatosis and large randomized clinical trials are warranted.
文摘Peritoneal carcinomatosis in gastric cancer is associated with a dismal prognosis.Systemic chemotherapy is not effective because of the existence of a blood-peritoneal barrier.Cytoreductive surgery and intraperitoneal chemotherapy can improve survival and quality of life in selected patients.Patient selection for this multimodal approach is one of the most critical issues,and calls for interdisciplinary evaluation by radiologists,medical and surgical oncologists,and anaesthetists.This article sets forth criteria for selection of gastric cancer patients suffering from peritoneal carcinomatosis.
文摘There are diverse protocols to manage patients with recurrent disease after primary cytoreductive surgery(CRS) with hyperthermic intraperitoneal chemotherapy(HIPEC) for peritoneal carcinomatosis. We describe a case of metachronous liver metastasis after CRS and HIPEC for colorectal cancer, successfully treated with a selective metastectomy and partial graft of the inferior vena cava. A 35-year-old female presented with a large tumour in the cecum and consequent colonic stenosis. After an emergency right colectomy, the patient received adjuvant chemotherapy. One year later she was diagnosed with peritoneal carcinomatosis, and it was decided to carry out a CRS/HIPEC. After 2 years of total remission, an isolated metachronous liver metastasis was detected by magnetic resonance imaging surveillance. The patient underwent a third procedure including a caudate lobe and partial inferior vena cava resection with a prosthetic graft interposition, achieving an R0 situation. The postoperative course was uneventful and the patient was discharged on postoperative day 17 after the liver resection. At 18-mo follow-up after the liver resection the patient remained free of recurrence. In selected patients, the option of re-operation due to recurrent disease should be discussed. Even liver resection of a metachronous metastasis and an extended vascular resection are acceptable after CRS/HIPEC and can be considered as a potential treatment option to remove all macroscopic lesions.

文摘BACKGROUND Primary extra-gastrointestinal stromal tumors(E-GIST)of the liver are rare.The clinical presentation may range from asymptomatic to bleeding or manifestations of mass effect.Oncologic surgery followed by adjuvant therapy with imatinib is the standard of care.However,under specific circumstances,a cytoreductive approach may represent a therapeutic option.We describe herein the case of an 84-year-old woman who presented with a tender,protruding epigastric mass.Abdominal computed tomography scan revealed a large,heterogeneous mass located across segments III,IV,V,and VIII of the liver.The initial approach was transarterial embolization of the tumor,which elicited no appreciable response.Considering the large size and central location of the tumor and the advanced age of the patient,non-anatomic complete resection was indicated.Due to substantial intraoperative bleeding and hemodynamic instability,only a near-complete resection could be achieved.Histopathology and immunohistochemical staining confirmed the diagnosis of primary E-GIST of the liver.Considering the risk/benefit ratio for therapeutic options,debulking surgery may represent a strategy to control pain and prolong survival.CASE SUMMARY Here,we present a case report of a patient diagnosed with E-GIST primary of the liver,which was indicated a cytoreductive surgery and adjuvant therapy with imatinib.CONCLUSION E-GIST primary of the liver is a rare conditional,the treatment is with systemic therapy and total resection surgery.However,a cytoreductive surgery will be necessary when a complete resection is no possible.
