OBJECTIVES To evaluate pathological response and clinical outcomes in women with locally advanced cervical cancer treated with chemoradiotherapy and surgery in a tertiary hospital. METHODS • • • • • • • • • • • Retrospective analysis. 59 patients with cervical cancer (FIGO stages IA-IVB) December 2004 and July 2015 with CCRT followed by surgery. EXTERNAL BEAM RADIOTHERAPHY (EBRT) at 46-50,4 Gy, 1,8-2 Gy/day. If aortic nodes were demonstrated, extended EBRT was administered. Boost to affected nodes or parametria (60 - 68 Gy, 2 Gy/day). After 4 weeks of treatment, brachytherapy from 15 to 26 Gy in 3-6 fractions with 2D planification or 3D planification (n=28) was administered. Total tumour dose (D2): 85 - 90 Gy. Concurrent chemo with weekly platin and in some cases oral 5-FU. Overall treatment time ≤ 8 weeks. All patients completed surgery between 4-15 weeks after CCRT. RESULTS • • • • Median age: 52y (30 - 77). Squamous cell carcinoma: 81%. All patients received hysterectomy. 7 patients (12%) underwent lymphadenectomy. • RESPONSE: • Complete response: 32 patients (54%). • Residual microscopic disease: 7 (12%). • Partial response: 20 (34%). • Median follow up: 53 months (2 - 128 m). • OS was 85% and DFS 81%. CONCLUSIONS ESTRO 2016 Our results show that CCRT followed by surgery gets excellent outcomes with acceptable toxicity and may reduce local recurrences. Besides, it enables assessment of the pathological response. 1311-EP Clinical track: Gynaecological (endometrium, cervix, vagina, vulva) Javier Tomás Anchuelo Latorre DOI: 10.3252/pso.eu.ESTRO2016.2016 Poster presented at:
