RECIST criteria v1.1 was used to assess response to NACT and toxicity was assessed using CTCAE v4.0. Survival analysis was done using Kaplan-Meir method. Univariate and multivariate analysis was done using Log-rank test and Cox-regression model respectively.Result(s)*104 patients (median age: 52 years) of advanced cervical cancer (92% SCC) received NACT for following reasons: bulky pelvic nodes (n=20), bulky para-aortic nodes (n=10), bulky pelvic + para-aortic nodes (n=31), bladder invasion (n=43). Baseline median pelvic and para-aortic nodal size was 2.5 cm (range: 1-8) and 1.8 cm (range: 1-3.5) respectively. Baseline median tumor infiltration size into bladder on cystoscopy was 3 cm (range 0.5-7). NACT regimen was Paclitaxel (175 mg/m2) and Carboplatin (AUC 5) 3 weekly IV infusion for 3 (median) cycles (range: 1-6). Post NACT completion, 9 (8.6%) defaulted from subsequent treatment, 8 (7.7%) were labeled as best supportive care, 1 received palliative chemotherapy for progressive disease and 13 (12.5%) patients received palliative RT. 73 (70.2%) patients received radical pelvic EBRT (median dose of 46Gy/23Fr) of which 68 (93.1%) received brachytherapy boost (median dose 21Gy/3Fr). 32 (43.8%) and 28 (38.3%) patients also received extended field RT (EFRT) and nodal boost (median dose 5.4Gy/3Fr) respectively. 64 (87.6%) patients received concurrent cisplatin. On univariate analysis, patients with comorbidities, bladder invasion, pelvic nodal disease, NACT dose reduction, incomplete radical treatment post-NACT and pelvic nodal size ≥ 2.5cm at baseline had poor outcomes (table 1). On multivariate analysis, none of the variables reached levels of significance. At median follow-up of 26 months (IQR: 11-45), 34 patients had died of disease, 51 were alive, of which 34 were disease-free. The 2 year LC, RC, DMC, DFS and OS for the entire cohort was 75%, 68%, 72%, 48% and 60% respectively whereas for the patents who completed NACT and radical local treatment was 92%, 82%, 76%, 62% and 75% respectively (figure 1).View this table:Abstract 787 Table 1 Univariate analysis of correlation of prognostic factors with LC, RC, DMC, RFS and OSAbstract 787 Figure 1 Kaplan meier curves for patients who completed NACT followed by radical local treatment (CTRT/RT + brachytheraphy boost)Conclusion*NACT followed by radiation therapy in non metastatic advanced cervical cancer is a feasible option with good survival outcomes and acceptable toxicity.
