Neoadjuvant chemotherapy for locally advanced cervical cancer: Experience at the Instituto Oncologico Nacional SOLCA Guayaquil.
e15571 Background: Cervical cancer is the most common malignancy of women in Ecuador. The main problem of concomitant chemo-radiotherapy (CRT) is the delay in starting radiation therapy, economic and logistical problems for high demand in radiotherapy. It has been neoadjuvant chemotherapy (NACT) followed by CRT the main treatment at our center in order to find an alternative to long waits before the start of radiotherapy. The aim of this study was to determine the response to NACT followed by CRT in terms progression-free survival (PFS) and overall survival (OS). Methods: diagnosed with invasive cervical cancer locally advanced stage II-III were analyzed retrospectively reviewed clinical records of pre-existing data from 2008 to 2010. Results: after meeting the criteria of exclusion, leaving 116 cases. The median age: 49 years (range: 28-82 years). The histology was 73% (85) squamous cell carcinoma, 26% (30) adenocarcinoma and 0.9% (1) not specified. Patients with stage IIB: 81.9% (95), IIIA: 10.3% (12), IIIB: 7.8% (9). Of the 116 patients 69% (80) received NACT. The main NACT was paclitaxel 175mg/m2 + Cisplatin 75mg/m2 every 3 weeks 63.8% (74), the remaining group received another protocol, the median number of cycles of NACT was 5 (1 - 8 cycles), the start of radiotherapy since the conclusion of NACT was 53 days on average (1 to 285 days) and the main regimen of CRT concomitant was cisplatin 40mg/m2 weekly 47.5% (38). In the 49 patients who underwent NACT followed by CRT, a radiological study showed, complete response (CR) 38.8% (19), 18.4% partial response (PR) (9), disease progression (DP) 12.2% (6), stable disease (SD) 8.2% (4) and the end of treatment evaluation gynecological was performed and CR was obtained in 59.2% (29). Persistent or progressive disease after treatment was 22.4% (11), recurrence was 12.2% (6), local recurrence 2.0% (1), distant metastasis 10.2% (5). OS of NACT followed by CRT was 93.9% (46) and PFS was 65.3% (32), OS after CR was 96% (25 / 1) and then 91.7% PR (24 / 2) with p: 0.439. Conclusions: NACT followed by CRT is a valid option because it improves disease-related symptoms, but OS did not improve significantly even after CR.
