Feasibility of neoadjuvant chemotherapy for bulky early stage to stage IIIB cervical cancer in Uganda.

INTRODUCTION

External beam radiotherapy (EBRT) became unavailable in Uganda from February 2016 to November 2017. Following resource stratification guidelines, an alternative treatment strategy was developed.

METHODS

Bulky early stage to Stage IIIB patients received at least 3 cycles of neoadjuvant chemotherapy (NAC). Surgery was performed if adequate response was achieved and adjuvant therapy given for high risk factors. Chemotherapy versus supportive care was advised in unresectable disease. NAC protocol completion was defined as receiving at least 3 cycles of NAC followed by either surgery, chemotherapy and/or radiation, or best supportive care. The purpose of this study was to determine the completion rate of NAC and assess the adverse events associated with treatment. Data were collected through retrospective chart review.

RESULTS

From February 2016 to November 2018, 53 evaluable patients were identified. 86.8% (46/53) of patients presented in Stage IIB or higher. The completion rate of the NAC protocol was 75.5% (40/53). 94.3% (50/53) received platinum-taxane combination. 7.6% (4/52) grade 3 adverse events occurred related to chemotherapy, all hematologic. 18.8% (10/53) patients underwent surgery with 2 aborted cases due to metastatic or inoperable disease. No adverse events related to surgery were reported. 5 patients underwent adjuvant therapy after surgery due to high risk factors or incomplete pathology findings. 26 patients received adjuvant radiation (3 brachytherapy, 23 EBRT after it became available). Reported side effects related to radiation included vaginal fibrosis and skin reactions.

CONCLUSION

In this limited-resource setting, majority of patients completed a NAC treatment strategy for cervical cancer with acceptable toxicities.
