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.

Twenty-years' experience with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP).

PURPOSE: Pseudomyxoma peritonei is treated with cytoreductive surgery (CRS) combined and hyperthermic intraoperative intraperitoneal chemotherapy (HIPEC). The purpose of this study was to report the20-year experience of one surgical team inCRS and HIPEC for PMP of appendiceal origin. METHODS: Retrospective study of the files of patients with PMP of appendiceal origin that underwent CRS+HIPEC. Morbidity and hospital mortality were recorded. Clinical and histopathologic variables were correlated to survival and recurrence. RESULTS: The files of 41 patients with PMP of appendiceal origin that underwent CRS+HIPEC from 1999-2018 were retrieved. The mortality and the morbidity rates were 2.4% and 29.3%, respectively. The 5- and 8-year survival rate was 68.3%. The completeness of cytoreduction, and the extent of previous surgery were identified as the prognostic indicators of survival. The recurrence rate was 32.5% with the completeness of cytoreduction, the histologic type of the tumor being the prognostic indicator. CONCLUSIONS: CRS in combination with perioperative intraperitoneal chemotherapy is a safe and effective treatment in the management of PMP of appendiceal origin.

Ovarian cancer: 20-year experience with cytoreductive surgery and perioperative intraperitoneal chemotherapy.

PURPOSE: Complete cytoreduction has been established as the most significant factor of long-term survival in epithelial ovarian cancer. Perioperative intraperitoneal chemotherapy has been added in the treatment of ovarian cancer the last 20 years. The purpose of the study was to determine the outcome of women with ovarian cancer using the data of one surgical team. METHODS: Women with ovarian cancer treated from 2000 to 2019 by the same surgical team were enrolled in the study. The patients underwent cytoreductive surgery combined with perioperative intraperitoneal chemotherapy. Clinical and histopathological variables were correlated to hospital mortality, morbidity, survival and recurrences. RESULTS: The mean age of 350 women was 59.5+11.7 years. The hospital mortality and morbidity rate were 2.0% and 28.3%, respectively. Complete cytoreduction was possible in 60% of the cases. The overall 5- and 10-year survival rate was 47% and 39%, respectively. The prognostic variables of survival were the extent of peritoneal malignancy, the extent of previous surgery, the grade of differentiation, the use of adjuvant chemotherapy, the lymphadenectomy of the resected large bowel, and the postoperative morbidity. The recurrence rate was 45.7%. The extent of peritoneal carcinomatosis, the extent of previous surgery, and the grade of differentiation were the prognostic variables of recurrence. CONCLUSIONS: The limited extent of peritoneal carcinomatosis in women with well differentiated ovarian cancer that do not have history of previous surgery, who undergo standard pelvic peritonectomy procedure, and receive adjuvant chemotherapy are expected to be long-term survivors.

Cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy in the treatment of rare tumors with peritoneal metastases.

PURPOSE: Cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC) is the standard treatment for tumors presented with peritoneal metastases (PM). Data in the literature about the treatment of rare tumors with PM are limited and of low-quality. The aim of the study was to assess the outcome and safety of CRS and HIPEC for these tumors. METHODS: Patients with rare tumors with PM that underwent CRS and HIPEC between 2005-2018, were retrospectively analyzed. Clinical and histopathological variables were correlated to survival. RESULTS: 43 patients, mean age 55.7 ± 12.9 years, underwent 48 cytoreductions. The most frequent histopathologic type was sarcomatosis (31.3%). The majority of the patients (70.8%) had limited extent of peritoneal disease. Complete or near-complete cytoreduction was achieved in 83.3% of the cases. Severe morbidity was recorded in 12.6%. The median disease-free survival and overall survival were 11 and 63 months, respectively. Although the completeness of cytoreduction was found to be significantly related to survival, the extent of peritoneal carcinomatosis was the single prognostic factor. CONCLUSIONS: CRS followed by HIPEC is an effective and safe method in the treatment of rare tumors with PM. Further large, well-designed prospective studies are needed to validate these results.

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.

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.
