ABSTRACT
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.
