Impact of vaginal brachytherapy in intermediate and high-intermediate risk endometrial cancer: a multicenter study from the FRANCOGYN group / 부인종양

OBJECTIVE: According to recent European Society of Medical Oncology, European Society of Gynaecological Oncology and European Society of Radiotherapy and Oncology guidelines, adjuvant vaginal brachytherapy (VB) is optional in patients with intermediate risk (IR) and high-intermediate risk (HIR) endometrial cancer (EC). The aim of this French retrospective, multicenter study was to assess the impact of VB in these groups on local recurrence rate, local recurrence-free survival (RFS) and overall survival (OS). METHODS: Data of 191 patients with IR and HIR EC who underwent primary surgery with or without VB and no other adjuvant treatment between 2000 and 2016 were extracted from the FRANCOGYN database. Rate of local recurrence, OS and local RFS in these two groups were compared using the Kaplan-Meier method. RESULTS: The number of patients with IR and HIR EC were 118 and 73 respectively. VB was used in 92 patients in IR group and 43 in HIR group. Median follow-up was 22 months. In the HIR group, the local recurrence rate was significantly higher in the no adjuvant therapy group in comparison with the VB group (16.7% and 0% respectively, p=0.02). There was also a significant improvement in local RFS (p=0.01) in VB group. In IR EC, there is no significant difference on local recurrence rate (4.2% and 3.2%, respectively, p=1.00) or local RFS (p=0.54) between the two groups. CONCLUSIONS: VB is an efficient adjuvant treatment for patients with HIR EC. VB is not associated with an improvement of RFS or OS in IR EC patient.

Early stage (IA-IB) primary carcinoma of the fallopian tube: case-control comparison to adenocarcinoma of the ovary / 부인종양

OBJECTIVE: Early stage primary carcinoma of the fallopian tube (PCFT) is an uncommon condition when strict criteria are applied. The aim of this study was to compare the outcome stage IA-IB PCFT to a matched group of ovarian cancer (OC). METHODS: Between 1990 and 2008, 32 patients with stage IA-IB of PCFT were recorded in the database of three French Institutions. A control group of patients with OC was constituted. RESULTS: Eleven eligible PCFT cases and 29 OC controls fulfilled the stringent inclusion criteria. Median follow-up was 70.2 months. Five-year overall survival was 83.3% (95% confidence interval [CI], 27.3 to 97.5) for PCFT and 88.0% (95% CI, 66.9 to 96.0) for OC (p=0.93). In the subgroup of patients with grade 2-3, the outcome was similar in PCFT compared to OC patients (p=0.75). Five-year relapse-free survival was respectively 62.5% (95% CI, 22.9 to 86.1) and 85.0% (95% CI, 64.6 to 94.2) in the PCFT and OC groups (p=0.07). In the subgroup of patients (grade 2-3), there was no difference between PCFT and OC (p=0.65). CONCLUSION: The findings did not reveal any difference in prognosis between early stage of PCFT and OC when grade is taken into account. Management of PCFT should mirror that of ovarian carcinoma.
