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.

Purpose To identify prognostic factors of survival and recurrence in advanced ovarian cancer patients undergoing radical surgery and HIPEC. Methods In a single Department of Surgical Oncology, Peritoneal Surface Malignancy Program, and over a 16-year period, from a total of 274 epithelial ovarian cancer patients, retrospectively, we identified 152 patients undergoing complete (CC-0) or near-complete (CC-1) cytoreduction, including at least one colonic resection, and HIPEC. Results Mean age of patients was 58.8 years and CC-0 was possible in 72.4%. Rates of in-hospital mortality and major morbidity were 2.6% and 15.7%. Only 122 (80.3%) patients completed Adjuvant Systemic Chemotherapy (ASCH). Rates of metastatic Total Lymph Nodes (TLN), Para-Aortic and Pelvic Lymph Nodes (PAPLN) and Large Bowel Lymph Nodes (LBLN) were 58.7%, 58.5%, and 51.3%, respectively. Median, 5- and 10-year survival rates were 39 months, 43%, and 36.2%, respectively. The recurrence rate was 35.5%. On univariate analysis, CC-1, high Peritoneal Cancer Index (PCI), in-hospital morbidity, and no adjuvant chemotherapy were adverse factors for survival and recurrence. On multivariate analysis, negative survival indicators were the advanced age of patients, extensive peritoneal dissemination, low total number of TLN and no systemic PAPLN. Metastatic LBLN and segmental resection of the small bowel (SIR) were associated with a high risk for recurrence. Conclusion CC-O is feasible in most advanced ovarian cancer patients and HIPEC may confer a survival benefit. Radical bowel resection, with its entire mesocolon, may be necessary, as its lymph nodes often harbor metastases influencing disease recurrence and survival. The role of metastatic bowel lymph nodes has to be taken into account when assessing the impact of systemic lymphadenectomy in this group of patients.

Cytoreductive Surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) results in significant morbidity and mortality and readmission. Previous studies have been limited with numbers or leak of tumor details. We analyzed a 15 year experience a total 730 Hipec procedures and the postoperative morbidity was 22.3% and mortality was 3.6% for the first month after initial operation. Complications with Dindo classification reached 39% in the first 90 postoperative days. The most common cause of delayed complications which demands re-admission was bowel obstruction and the second is rectovaginal fistulas and pulmonary embolism.
