ABSTRACT
Objective:To explore the prognosis of epithelial ovarian cancer patients with multiple recurrences (≥2 times) who underwent three times or more cytoreductive surgeries, and to analyze the factors associated with prognosis.Methods:The clinicopathological data and follow-up data of 23 patients with ovarian cancer admitted to the Obstetrics and Gynecology Hospital of Fudan University from January 1, 2015 to January 30, 2022 with three times or more cytoreductive surgeries were collected. The degree of surgical resection, site of recurrence and metastasis, postoperative complications, and prognosis were retrospectively analyzed. The univariate Cox proportional hazards model was performed to identify the variables associated with survival.Results:(1) The median age of 23 patients with multiple recurrent ovarian cancer was 48 years old (44-55 years). Among them, 18 cases underwent tertiary cytoreductive surgery (TCS), 2 cases underwent quaternary cytoreductive surgery, 2 cases underwent quinary cytoreductive surgery, and 1 case underwent senary cytoreductive surgery. Among the 23 patients with multiple recurrent ovarian cancer, 21 cases (91%, 21/23) had serous carcinoma, 16 cases (70%, 16/23) had advanced stage (stage Ⅲ-Ⅳ), and 19 cases (83%, 19/23) had high differentiation. (2) Based on the premise that satisfactory cytoreduction was achieved by primary debulking surgery (PDS) and no visible residual disease (R0) was achieved by secondary cytoreductive surgery (SCS), the maximum diameter of the recurrent tumors was up to 10.0 cm and 62% (20/32) of patients with multiple metastatic sites. The R0 rate for three times or more cytoreductive surgeries (32 times in total) reached 88% (28/32), with a postoperative complication rate of 47% (15/32), and only 3% (1/32) for grade Ⅲ or above. During a median follow-up time of 31.1 months (20.6-43.9 months) after TCS, 20 patients (87%, 20/23) recurred after TCS, and 8 patients (35%, 8/23) eventually died of ovarian cancer. Among them, the three-year postoperative survival rate of 22 patients with R0 was 57.6%, and the patient with residual lesions ≥1 cm died at 9.2 months after TCS. (3) In univariate analysis, ages, the time interval between PDS and SCS >32 months, the interval between SCS and TCS >16 months, and no metastatic peritoneal carcinoma were associated with longer progression free survival after TCS (all P<0.05); while treatment-free interval (TFI) >10 months after SCS, the interval between SCS and TCS >16 months, no ascites and platinum-sensitive status were associated with disease-specific survival after TCS (all P<0.05). Conclusions:It is feasible to perform three times or more cytoreductive surgeries in patients with multiple recurrent ovarian cancer who are expected to achieve R0 and have manageable complications. However, the pros and cons of surgery need to be carefully evaluated for the patients whose ascites are massive and whose previous cytoreduction does not achieve R0. A prolonged TFI and previously longer surgical interval might get potential survival benefits.
ABSTRACT
The prevention and treatment of posthepatectomy liver failure (PHLF) is a difficult problem for hepatectomy. PHLF is characterized by many risk factors, limited treatment methods and high mortality. There are many factors that lead to the insufficient quantity or quality of postoperative remnant liver cells, such as the comorbid conditions of patients, underlying disease of the liver, excessive liver resection and so on, which are increase the incidence of PHLF. However, the therapeutic treatment of PHLF is limited at present, the key to reduce the morbidity and mortality of PHLF lies in the accurate evaluation and screening of high-risk patients. This paper reviewed the relevant literature on the definition, risk factors and clinical prevention and treatment of posthepatectomy liver failure.
