    Para-aortic lymph node involvement revisited in the light of the revised 2018 FIGO staging system for cervical cancer
    (2019) Ayhan, Ali; Aslan, Koray; Oz, Murat; Tohma, Yusuf Aytac; Kuscu, Esra; Meydanli, Mehmet Mutlu; 0000-0001-9418-4733; 31263988
    Objective This dual-institutional, retrospective study aimed to determine the clinicopathological risk factors for para-aortic lymph node (LN) metastasis among women who underwent radical hysterectomy with systematic pelvic and para-aortic lymphadenectomy for 2009 FIGO stage IB1-IIA2 cervical cancer. Methods Institutional cervical cancer databases of two high-volume gynecologic cancer centers in Ankara, Turkey were retrospectively analyzed. Women with 2009 FIGO stage IB1-IIA2 cervical cancer that had undergone radical hysterectomy with pelvic and para-aortic lymphadenectomy between January 2006 and December 2018 were included in the study. Patient data were analyzed with respect to para-aortic LN involvement and all potential clinicopathological risk factors for para-aortic LN metastasis were investigated. Results A total of 522 women met the inclusion criteria. Pelvic LN metastasis was detected in 190 patients (36.4%), para-aortic LN metastasis in 48 patients (9.2%), isolated para-aortic LN metastasis in 4 (0.8%), and both pelvic and para-aortic LN metastasis in 44 (8.4%) women, respectively. The independent risk factors identified for para-aortic LN involvement included parametrial invasion (odds ratio [OR]: 3.57, 95% confidence interval [CI]: 1.65-7.72; p = 0.001), metastasized pelvic LN size > 1 cm (OR: 4.51, 95% CI: 1.75-11.64; p = 0.002), multiple pelvic LN metastases (OR: 3.83, 95% CI: 1.46-10.01; p = 0.006), and common iliac LN metastasis (OR: 2.97, 95% CI: 1.01-8.68; p = 0.04). A total of 196 (37.5%) patients exhibited at least one risk factor for para-aortic nodal disease. Conclusion Parametrial invasion, metastasized pelvic LN size > 1 cm, multiple pelvic LN metastases, and common iliac LN metastasis seem to be independent predictors of para-aortic LN involvement.

    Is the revised 2018 FIGO staging system for cervical cancer more prognostic than the 2009 FIGO staging system for women previously staged as IB disease?
    (2019) Ayhan, Ali; Aslan, Koray; Bulut, Ayca Nazli; Akilli, Huseyin; Oz, Murat; Haberal, Ali; Meydanli, Mehmet Mutlu; 0000-0002-7495-5470; 31325847
    Objective: The purpose of this study was to compare the prognostic value of the revised FIGO staging system with that of the 2009 FIGO staging system for women previously staged as IB disease. Methods: Institutional cervical cancer databases of two high-volume gynecologic cancer centers in Ankara, Turkey, were retrospectively analyzed. Only women with 2009 FIGO stage IB1 or 1B2 disease who underwent primary surgery were included. Survival curves were generated using Kaplan-Meier plots, and the log-rank test was used for survival comparisons. The Cox proportional hazards regression model was used to obtain hazard ratios (HRs) and 95% confidence interval (CI). Results: Data from 425 women were analyzed. The 2009 FIGO stage IB2 (n = 131) disease was associated with a nearly three-fold increased risk of mortality when compared to the 2009 FIGO stage IB1 (n = 294) disease (HR: 2.72, 95% CI: 1.69-4.37; p < 0.001). Stage migration was observed in 372 (87.5%) patients, according to the revised FIGO staging system, leading to no significant difference in five-year overall survival rates between stage IB1 (n=53) and IB2 (n=127) disease (95.2% vs. 89.3%, respectively; p = 0.23),or between stage IB2 (n=127) and IB3 (n=95) disease (89.3% vs. 84.2%, respectively; p = 0.12). Similarly, there was no significant difference in five-year overall survival rates between stage IIIC1 (n=114) and IIIC2 (n=36) disease (79.0% vs. 67.2%, respectively; p = 0.34). Conclusion: When compared to the 2009 FIGO staging system, the revised staging system has more substages, which leads to fewer patients in each sub-stage, resulting in diminished statistical power.
