- W2946876162 abstract "e17010 Background: With revisions to FIGO cervical cancer staging system in 2018, patients with positive pelvic or para-aortic lymph nodes (LN) are now classified as stage IIIC. Rationale for this change is based on data published in 1990. Methods for work up and treatment of cervical cancer have advanced since then. We aim to determine if updated FIGO staging reflects contemporary survival differences in women with cervical cancer in Louisiana. Methods: Women with FIGO stage I-III cervical cancer diagnosed between 2010 and 2016 were identified from the Louisiana Tumor Registry. Those with < 30 days follow up were excluded. Patients were classified into 3 groups: true stage I & II (LN negative), revised stage IIIC (old stage I or II but positive LN), previous stage III (old FIGO stage IIIA or IIIB). Cox proportional hazards were used to estimate differences in overall and (OS) cause-specific survival (CSS). Covariates of age, race, insurance, census-tract poverty level, and marital status were controlled. Results: 740 patients were included with a median follow up of 40.6 months. Patients in revised stage IIIC group were younger than the others (45.9 yrs vs 47.9 yrs in true stage I&II vs 55yrs in previous stage III, p < 0.0001). True stage I&II patients were more likely to be privately insured (48.9% vs 32.1% revised stage IIIC vs 27.7% previous stage III, p < 0.0001). The groups did not differ by race, poverty level, or marital status. Revised stage IIIC and previous stage III patients had significantly worse survival outcomes compared to true stage I & II in both OS [revised stage IIIC HR 1.93 (1.20-3.11); previous stage III 5.92 (4.27, 8.22)] and CSS [revised stage IIIC HR 2.54 (1.45-4.44); previous stage III HR 7.95 (5.29, 11.94)]. Kaplan-Meier survival curves demonstrate significant differences in both OS and CSS (p < 0.0001) with best outcomes in true stage I&II and worst in previous stage III patients. Conclusions: LN status is an important prognostic indicator for contemporary cervical cancer patients in Louisiana. This analysis provides recent data to support the revised FIGO staging system in upstaging patients with positive LN to stage IIIC as they have significantly worse survival than the true stage I & II patients. Importantly, revised stage IIIC patients who would have previously been stage I & II have strikingly better survival outcomes than women with stage IIIA and IIIB disease. If staging is to be intuitive, the stage III subcategories may need to be redefined." @default.
