This retrospective observational study evaluated the use of NACT in LACC and identified tumor diameter, lymphovascular space invasion, and parametrium involvement as independent risk factors for response to NACT. Tumor initial diameter was found to be an independent prognostic predictor for overall and lymph node response. Tumors with diameter between 2 and 6 cm showed a better response to NACT compared to tumors larger than 6 cm, and LVSI absence was an independent prognostic factor for lymph node response to NACT.
Background: Several pretreatment variables have been found to correlate with the clinical outcome of patients treated with NACT plus radical hysterectomy, such as FIGO stage, tumor size, and lymph node status. Methods: A single-center retrospective observational study to evaluate the use of NACT in LACC, particularly in the lymph-node-positive subpopulation. The study, conducted at the Maternal and Child Department of Cannizzaro Hospital in Catania, included patients treated between 2009 and 2019. Multivariate analysis was performed to analyze responses to NACT according to clinicopathologic parameters. Kaplan-Meyer disease-free survival (DFS) and overall survival (OS) curves were generated according to different lymph node status subgroups. Results: A total of 151 consecutive patients were enrolled in the study. Significant independent risk factors for response to NACT were preoperative tumor diameter, parametrium involvement, and lymphoma vascular space invasion (LVSI). T initial diameter at NMR was found to be the independent prognostic predictor for general (p = 0.024) and lymph node (LND) response (p = 0.028). Tumors between 2 and 6 cm have a better response to NACT than tumors > 6 cm, and LVSI absence was an independent prognostic factor for LND response to NACT. Survival DFS and OS curves were significant for positive vs. negative pathologic LND. Conclusions: Neoadjuvant chemotherapy followed by surgery cannot be considered a standard of care in patients with locally advanced cervical cancer, particularly in the subgroup with pre-NACT imaging suspected for LND metastases.
