Abstract
Our goal was to determine the clinical treatment response following radiation administered with or without chemotherapy for locally advanced cervical cancers in Honduras. This is a retrospective study of patients treated with either concurrent chemoradiation (CCRT) or external beam radiation therapy (EBRT) alone at a hospital in Tegucigalpa, Honduras. 70 Gy of EBRT to the pelvis was given in all cases. Brachytherapy was not available. Chemotherapy was given when available. Extrafascial hysterectomy was performed 6 weeks after completion of treatment in patients with a complete clinical response (cCR). Records for 165 women with locally advanced cervical cancer were reviewed; 25 (15.2%) stage IB2, 15 (9.1%) stage IIA, 90 (54.5%) stage IIB, and 35 (21.2%) stage IIIB. Ninety (54.5%) patients received EBRT alone; 75 (45.5%) received CCRT. Twenty-three (33.3%) of CCRT patients received weekly cisplatin, the remainder receiving other agents. Seventy (77.8%) of the 90 patients who received EBRT had a cCR; 25 out of 75 (33.3%) patients in the CCRT group achieved a cCR. The CCRT group treated with weekly cisplatin achieved an 80% cCR; while the CCRT group given alternative agents had only a 31% cCR. Patients unable to receive platinum-based CCRT had the worst outcome, and their responses were inferior to patients who received EBRT. The challenges of treating women with locally advanced cervical cancer in a low-resource setting are multifactorial and include treatment delays, the lack of brachytherapy and the unpredictable availability of chemotherapy.
The treatment of cervical cancer in low-resource settings is challenging.
Among our patients, those unable to receive platinum-based CCRT had worse outcomes.
Treatment delays, due to unavailability of cisplatin, led to worse outcomes.
