Treatment outcomes of concurrent weekly cisplatin with intracavitary brachytherapy in patients with cervical carcinoma, pre-treated with concurrent chemo-radiotherapy

Abstract

Objective: Cervical carcinoma is one of the leading causes of cancer-related deaths. This study evaluates improvement of quality of life, response to treatment, and compliance of concurrent weekly cisplatin with intracavitary brachytherapy (ICRT) in patients with cervical carcinoma, pre-treated with concurrent chemo-radiotherapy. Materials and Methods: This study was conducted in the Department of Radiotherapy, Government Medical College, from October 2018 to March 2020, meeting specified inclusion and exclusion criteria; patients willing to participate in the study were included. Results: On analyzing the pattern of response, 91.0% of patients have a complete response. The incidence of nausea and vomiting was observed at grade 1 or 2 in 80.0% of patients, grade 3 in 17.0% of patients, and more than grade 3 in 3.0% of patients. Neutropenia is occurred at less than grade 3 in 30.0% of patients and grade 3 or more in 3.3% of patients. Vaginal mucositis was also observed in 85.0% of the patients in less than grade 3 and 11.6% in grade 3 or more. The incidence of renal dysfunction less than grade 3 was seen in 35.0% of the patients and grade 3 or more in 5.0% of the patients. After 6months, there was cystitis found in less than grade 3 in 10.0% of the patients and more than grade 3 in 3.3% of the patients. Conclusion: In locally advanced squamous cell carcinoma of the uterine cervix, the addition of concurrent injection of cisplatin to ICRT significantly improves locoregional response but increases the incidence of hematological and mucosal toxicity, which is manageable.
