Analysis of prognosis and influencing factors of secondary cytoreductive surgery combined with chemotherapy for recurrent ovarian cancer / 中华内分泌外科杂志

Objective:To investigate the prognosis and influencing factors of secondary cytoreductive surgery (SCS) combined with chemotherapy in the treatment of recurrent ovarian cancer.Methods:A total of 102 patients with recurrent ovarian cancer admitted to our hospital from Jun. 2012 to Jun. 2015 were selected and grouped according to treatment methods. 31 patients who received paclitaxel/carboplatin (TC) chemotherapy were included in the control group, and 71 patients who received SCS combined with TC chemotherapy were included in the observation group. Clinical efficacy and 5-year survival outcome of the two groups after treatment, were compared and factors affecting the prognosis of the observation group were analyzed.Results:The total effective rate, 1-year survival rate, 3-year survival rate, and 5-year survival rate of the observation group were significantly higher than those of the control group. The median survival time of the observation group was 52 months and was significantly longer than that of the control group by 17 months ( P<0.05) ; There was no statistical difference between the death group and the survival group in terms of age, pathological type, tissue differentiation, recurrence tumor size, or location of recurrence tumors. The number of patients with FIGO stage IV, more than 3 recurrent tumors, ascites and residual lesion size >1 cm in the death group were significantly larger than those in the survival group. The serum CA125 level of patients in the death group was significantly higher than that in the survival group. Logistic regression analysis showed that the number of recurring tumors>3, with ascites, and residual lesions>1 cm, and high level of CA125 were independent risk factors for death after SCS combined with TC chemotherapy ( P<0.05) . Conclusions:SCS combined with chemotherapy can effectively improve the therapeutic effect, relieve the clinical symptoms, improve the survival rate of patients, and prolong the survival time of patients. The prognosis of SCS combined with chemotherapy is affected by the number of recurrent tumors, the presence or absence of ascites, the size of residual lesions, and CA125 level. The prognosis and survival of patients can be improved by adopting appropriate treatment.

Progress of Surgery on Platinum-sensitive Recurrent Ovarian Cancer / 肿瘤防治研究

The high incidence and fatality rate of recurrent ovarian cancer (ROC) have always been the clinical problem. For part of patients with platinum-sensitive recurrent ovarian cancer, the secondary cytoreductive surgery (SCS) followed by platinum-based combination chemotherapy can prolong their survival time and improve quality of life. Therefore, it's a critical matter to accurately identify the patients who will benefit from surgery treatment. Several predictive models have been proposed for the selection of the patients for SCS. This article summarizes the research progress in the surgical treatment of platinum-sensitive recurrent ovarian cancer in recent years.

Prognostic factors of secondary cytoreductive surgery for patients with recurrent epithelial ovarian cancer / 부인종양

OBJECTIVE: The objective of this study was to identify the prognostic factors of secondary cytoreductive surgery on survival in patients with recurrent epithelial ovarian cancer. METHODS: The medical records of all patients who underwent secondary cytoreductive surgery between May 2001 and October 2007 at the National Cancer Center, Korea were reviewed. Univariate and multivariate analyses were executed to evaluate the potential variables for overall survival. RESULTS: In total, 54 patients met the inclusion criteria. Optimal cytoreduction to or =12 months vs. 24 months for PFS or =12 months. Secondary cytoreductive surgery should be offered in selected patients and large prospective studies are needed to define the selection criteria for secondary cytoreductive surgery.

Clinical analysis for the prognostic factors in patients with recurrent epithelial ovarian cancer who underwent secondary cytoreductive surgery / 부인종양

OBJECTIVE: To identify clinical prognostic factor improving survival of recurrent epithelial ovarian cancer (EOC) patients treated with secondary cytoreductive surgery (SCS). METHODS: The indications of SCS were as follows; 1) complete response (CR) after primary cytoreductive surgery and adjuvant chemotherapy, 2) disease-free survival (DFS) (> or =6 months). Clinical data of 17 patients including age, DFS, peritoneal seeding identified during SCS, the number of recurrent tumors (> or =1 cm), serum CA-125 levels and maximal diameter of residual tumor after SCS were reviewed retrospectively between January 1990 and March 2007. Survival analyses were performed using Kaplan-Meier method with log-rank test and univariate Cox's regression analysis. RESULTS: Mean age of them was 51.7 years. No peritoneal seeding identified during SCS was a prognostic factor improving progression-free survival after SCS (PFS-SCS) (30 vs. 6 months, p<.01 hazard ratio 0.099, 95% confidence interval 0.011-0.929, p=.043). Furthermore, serum CA-125 level (< or =37 U/ml) after SCS was a significant prognostic factors improving overall survival (51 vs. 19 months, p=.033; hazard ratio 0.212, 95% confidence interval 0.045-0.983, p=.045). CONCLUSION: Serum CA-125 levels with normal value after SCS and no peritoneal seeding may be associated with the improvement of survival in recurrent epithelial ovarian cancer patients treated with SCS.

The results of secondary cytoreductive surgery and second-line chemotherapy for patients with epithelial ovarian cancer / 中国癌症杂志

6 months was 42.3 months, longer than 17.5 months for patients with PFI ≤ 6 months, no statistical significance was found ( P =0.1418). Multivariate analysis strongly suggested that PFI and the courses of second line chemotherapy were independent prognostic factors of survival after secondary treatment for epithelial ovarian cancer. For those patients with PFI ≤ 6 months, the smaller the size of residual lesion ( P =0.0003) and the more the cycle of effective second line chemotherapy ( P =0.0004), the longer the survival after the secondary cytoreduction. Conclusions:The results suggested that successful secondary cytoreductive surgery combined with multicycles second line chemotherapy may be an effective way to lengthen the survival on retreatment for patients with platinum resistant and recurrent epithelial ovarian cancer.
