Ten-year experience with peritoneal mesothelioma.

PURPOSE: Peritoneal mesothelioma is a rare disease that remains confined to the peritoneal surfaces for long. Cytoreductive surgery (CRS) combined with hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) is the most effective treatment and complete cytoreduction is the most significant prognostic indicator of long-term survival. This study attempted to present the results of CRS in combination with hyperthermic intraperitoneal chemotherapy in patients with peritoneal mesothelioma and identify the prognostic indicators of survival. METHODS: The files of patients with peritoneal mesothelioma were retrospectively reviewed. Morbidity, hospital mortality, recurrences, and the sites of recurrence were recorded. Survival and recurrence were correlated to performance status, age, extent of peritoneal dissemination, tumor grade, tumor volume, and completeness of cytoreduction. RESULTS: From 2005-2017, 29 patients underwent 33 cytoreductions for peritoneal mesothelioma. Hospital mortality and morbidity were 3% and 27.3% respectively. The median and 8-year survival were 66 and 62% months, respectively. The completeness of cytoreduction was the single prognostic indicator of survival, and the tumor grade the single prognostic indicator of recurrence. CONCLUSION: CRS combined with HIPEC is the therapeutic strategy that may provide long-term survival.

Cytoreductive Surgery in Combination with HIPEC in the Treatment of Peritoneal Sarcomatosis.

Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective treatment for peritoneal carcinomatosis, but it has been debated for peritoneal sarcomatosis. The purpose of the study is the presentation of perioperative and long-term results of CRS and hyperthermic intraoperative intraperitoneal chemotherapy in patients with peritoneal sarcomatosis. Retrospective study in a prospectively maintained database of 20 patients that underwent 29 CRS + HIPEC for peritoneal sarcomatosis. Clinical and histopathologic variables were correlated to survival. Complete cytoreduction was possible in 86.2% of the cases. The hospital mortality and morbidity rate were 0 and 20.7%, respectively. The median follow-up was 26 months, and recurrence was recorded in 20 cases (69%). The median and 5-year survival was 55 ± 13 (34-58) months and 43%, respectively. Prior surgical score (PSS) was the single variable related to survival (p = 0.018). The histologic subtype of the tumor was related to recurrence (p < 0.001). CRS and HIPEC in peritoneal sarcomatosis may offer a survival benefit in selected patients with low hospital mortality. The variety of histologic types of sarcomatosis has not made possible the identification of subgroups of patients that may be offered significant benefit by CRS and HIPEC. Further studies are required.

Cytoreduction and HIPEC for peritoneal carcinomatosis of pancreatic cancer.

PURPOSE: Peritoneal carcinomatosis of pancreatic cancer is generally considered for palliative treatment. The purpose of this study was to report the outcome of cytoreductive surgery and hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) in patients with pancreatic cancer and peritoneal carcinomatosis. METHODS: Patients with documented resectable peritoneal carcinomatosis of pancreatic cancer underwent cytoreductive surgery in combination with HIPEC from 2008-2016 by the same surgical team. RESULTS: Six patients underwent 8 cytoreductions. Complete or near-complete cytoreduction was possible in 7 cases, and palliative surgery in one case. Gemcitabine was used in 5 cases during HIPEC, and cisplatin+mitomycin-C in 2 others. All patients received adjuvant chemotherapy with gemcitabine. Four patients survived without evidence of recurrence for more than 12 months. CONCLUSIONS: Cytoreductive surgery with HIPEC may be considered a treatment option in highly selected patients with pancreatic cancer and peritoneal carcinomatosis.

Cytoreductive surgery and hyperthermic intraperitenoal chemotherapy (HIPEC) for colorectal and appendiceal carcinomas with peritoneal carcinomatosis.

PURPOSE: Cytoreductive surgery combined with intraperitoneal chemotherapy has been established as the standard treatment for selected patients with peritoneal malignancy. The purpose of the study was the presentation of the 10- year experience with cytoreductive surgery and intraperitoneal chemotherapy in patients with peritoneal carcinomatosis of colorectal and appendiceal origin. METHODS: Clinical and histopathological variables were retrospectively reviewed in a prospectively maintained database. All patients underwent cytoreductive surgery with the purpose of complete or near-complete cytoreduction. The variables were correlated to survival, and recurrences. Morbidity and hospital mortality were recorded. RESULTS: From 2006-2016 100 patients underwent cytoreductive surgery for colorectal and appendiceal carcinomas with peritoneal carcinomatosis. The hospital mortality and morbidity were 2% and 43% respectively. Completeness of cytoreduction (CC) 0 surgery was possible in 51% of the patients. The median and 10-year survival were 13 months and 23% respectively. The completeness of cytoreduction, performance status and the lymph node status were identified as prognostic indicators of survival. The recurrence rate was 55%. The completeness of cytoreduction, the lymph node status, and the use of postoperative adjuvant systemic chemotherapy were identified as prognostic variables of recurrence. CONCLUSION: Nearly half of the patients with peritoneal carcinomatosis of colorectal and appendiceal origin may undergo complete cytoreduction and nearly half of them may enjoy long-term survival.

The effect of hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC) as an adjuvant in patients with resectable pancreatic cancer.

Background - aims: The long-term survival of pancreatic cancer is poor even after potentially curative resection. The incidence of local-regional failures is high. There is evidence that hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC) is effective in controlling the local-regional failures. The purpose of the study is to identify the effect of HIPEC after surgical removal of pancreatic carcinoma. Patients - Methods: Prospective study including 33 patients with resectable pancreatic carcinomas. All patients underwent surgical resection (R0) and ΗIPEC as an adjuvant. Morbidity and hospital mortality were recorded. The patients were followed-up for 5 years. Survival was calculated. Recurrences and the sites of failure were recorded. RESULTS: The mean age of the patients was 67.8 ± 11.1 years (38-86). The hospital mortality was 6.1% (2 patients) and the morbidity 24.2% (8 patients). The overall 5-year survival was 24%. The mean and median survival was 33 and 13 months, respectively. The median follow-up time was 11 months. The recurrence rate was 60.6% (20 patients). Three patients were recorded with local-regional failures (9.1%) and the others with liver metastases. CONCLUSIONS: It appears that HIPEC as an adjuvant following potentially curative resection (R0) of pancreatic carcinoma may effectively control the local-regional disease. Prospective randomised studies are required.

Total invasion of the pancreatic gland by a rare aggressive IPMN: Report of a case.

INTRODUCTION: The intraductal papillary mucinous neoplasms (IPMNs) are increasingly diagnosed entities with high potential of malignancy and significant recurrence rates. PRESENTATION OF CASE: In this case report a rare mixed IPMN with full invasion of the pancreatic ducts was identified. DISCUSSION: Difficulties in determining the grade of pancreatic duct involvement make the surgical management tough. CONCLUSION: In multifocal IPMNs the management of the patients is even more challenging. In this case the patient was treated successfully with total pancreatectomy.

Cytoreductive surgery combined with hyperthermic intraperitoneal intraoperative chemotherapy in the treatment of advanced epithelial ovarian cancer.

Background/Aims. Intraperitoneal intraoperative hyperthermic chemotherapy (HIPEC) has been used in the treatment of ovarian cancer. The purpose of the study is to determine the efficacy of HIPEC after cytoreductive surgery in advanced ovarian cancer. Patients/Methods. From 2006 to 2010 patients with advanced ovarian cancer were enrolled in a prospective nonrandomized study to undergo cytoreductive surgery combined with HIPEC. Clinical and histopathological variables were correlated to hospital mortality, morbidity, survival, and recurrences. Results. The mean age of 43 women was 59.9 ± 13.8 (16-82) years. The hospital mortality and morbidity rate were 4.7% and 51.2%, respectively. Complete cytoreduction was possible in 69.8%. The overall 5-year survival rate was 54%. The prognostic indicators of survival were the extent of prior surgery (P = 0.048) and the extent of peritoneal dissemination (P = 0.011). The recurrence rate was 30.2%. Conclusions. Maximal cytoreductive surgery combined with HIPEC is a well-tolerated, feasible, and promising method of treatment in advanced ovarian cancer.
