The experimental group included 27 patients with complete clinical response, whereas the control group comprised 31 patients with complete pathomorphological response (ypT0n0m0) who had undergone total mesorectal excision following neoadjuvant therapy. The main evaluated parameters included postoperative complications, proportion of R0 resections, proportion of sphincter-preserving surgeries, 2-year overall survival, and progression-free survival.Results. At a median follow-up time of 41 months (range: 25–114 months), 2 patients from the experimental group had progressive disease registered 18 and 19 months after treatment initiation; both patients underwent abdominoperineal extirpation of the rectum. The remaining 25 patients had sphincter sparing surgeries. At a median follow-up time of 48 months (range: 24–101 months), one patient was found to have liver metastasis 5 months following treatment initiation. He underwent simultaneous surgery that included low anterior resection of the rectum and liver resection and had no postoperative complications. In the group of surgical treatment, all patients underwent radical surgeries (R0), including those with permanent stoma formation (n = 11; 35.5 %) or preventive stoma formation (n = 20; 64.5 %) with subsequent bowel repair. The 2-year overall survival rate was 100 % in both groups. The 2-year progression-free survival rate was 92.6 % in the experimental group and 96.8 % in the control group (p = 0.473).Conclusion. The watch and wait strategy with active dynamic follow-up is a safe alternative to surgery in patients with complete clinical response after neoadjuvant therapy, since it ensures the results equivalent to those in patients with complete pathomorphological response.","PeriodicalId":34449,"journal":{"name":"Tazovaia khirurgiia i onkologiia","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41730303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lesion of the LN in recurrent Ос varies from 12 % to 37 %, but an isolated recurrence in the LN is a very rare occurrence, about 5 %. The most common localization in recurrent ОС with isolated LN lesion is the paraaortic LN.The results of this literature review suggest that isolated Ln lesion should be clearly distinguished from recurrence at other sites (such as peritoneal and parenchymal), since patients with isolated recurrence in the LN have a relatively indolent course of the disease. The frequency of complete cytoreduction according to the available data of retrospective studies reaches 100 %. Paraaortic and pelvic lymph node dissection without a macroscopically detectable residual tumor in combination with postoperative systemic chemotherapy leads to improved survival rates compared only with systemic drug treatment of patients with isolated LN lesion in recurrent ОС. median survival from the moment of relapse detection and overall survival varies from about 2.5 to 4 years and >5 years, respectively.

The retrospective analysis included patients under the age of 75 who underwent surgery for recurrence of OC with Ln involvement at n.n. Blokhin national medical Research Center of Oncology in the period from 2005 to 2020. All patients had previously received combined treatment due to a primary diagnosis of OC. Exclusion criteria: the presence of concomitant pathology in the decompensation phase, primary multiple malignant tumors and recurrences of non-epithelial ovarian tumors. The analysis of the main operational characteristics, the frequency of postoperative complications according to Clavien–Dindo within 30 days after surgery, PfS, OS, as well as parameters affecting the long-term results of treatment were performed.Results. The study included 123 patients: a cohort of isolated lesions of the Ln (n = 65) and a group of combined recurrence in the Ln and other anatomical locations (n = 58). The frequency of complete cytoreduction was significantly higher in the group of patients with isolated recurrence in the Ln: 86.62 % versus 53.4 % in patients with combined relapse, p <0.0001. The median duration of the operation was also significantly higher in patients with combined recurrence: 245 min versus 180 min in a cohort of patients with isolated recurrence in the Ln, p <0.0001.

Only patients with favorable prognosis (tumor located at least 5 cm above the transitional anal fold and no history of chemoradiotherapy) were included.

The controls were randomly selected and matched cases for tumor size, presence of diabetes mellitus (Dm), and ASA physical status. we evaluated the incidence of grade ≥III complications (Clavien–Dindo classification), clinically significant pancreatic fistulas, Dm, and impaired exocrine pancreatic function in the late postoperative period.Results.
