- Abstract
Introduction: Although complete cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) offers a good prognosis in patients with peritoneal metastasis of ovarian cancer (PMOC), recurrences are quite common. These recurrences can be intra-abdominal or systemic in nature. Our objective was to study and illustrate the global recurrence pattern in patients operated for PMOC, shedding light on a previously overlooked lymphatic basin at the level of the epigastric artery, the deep epigastric lymph nodes (DELN) basin., Patients and Methods: This was a retrospective study including patients with PMOC who underwent surgery with curative-intent, from 2012 until 2018, at our cancer center, and who presented with any type of disease recurrence on follow-up. CT-scans, MRIs and PET-scans were reviewed in order to determine solid organs and lymph nodes (LN) recurrences., Results: During the study period, 208 patients underwent CRS ± HIPEC, 115 (55.3%) presented with organ or lymphatic recurrence over a median follow-up of 81 months. Sixty percent of these patients had radiologically enlarged LN involvement. The pelvis/pelvic peritoneum was the most common intra-abdominal organ recurrence site (47%), while the retroperitoneal LN was the most common lymphatic recurrence site (73.9%). Previously overlooked DELN were found in 12 patients, with 17.4% implication in lymphatic basin recurrence patterns., Conclusion: Our study revealed the potential role of the DELN basin, previously overlooked in the systemic dissemination process of PMOC. This study sheds light on a previously unrecognized lymphatic pathway, as an intermediate checkpoint or relay, between the peritoneum, an intra-abdominal organ, and the extra-abdominal compartment., Competing Interests: Declaration of competing interest Authors declare no conflict of interest., (Copyright © 2023 The Authors.
