Comparison of response and toxicity of induction chemotherapy with cisplatin and 5-fluorouracil versus cisplatin and paclitaxel followed by concurrent chemoradiotherapy in advanced head and neck cancer

Background Head and neck cancer poses a prevalent oncological challenge in Bangladesh, often diagnosed in advanced stages. Standard treatment for inoperable cases involves concurrent chemo-radiotherapy, but induction chemotherapy has shown significant benefits. This study aimed to compare the response and toxicity of induction chemotherapy with cisplatin and 5-fluorouracil versus cisplatin and paclitaxel followed by concurrent chemo-radiotherapy in advanced head and neck cancer.

Methods From January 2019 to June 2020, a multicenter study enrolled 150 cases with inoperable squamous cell carcinomas in the head and neck. Ethical approval was obtained from Bangabandhu Sheikh Mujib Medical University. Divided into two arms, Arm A had 75 patients receiving cisplatin and 5-fluorouracil, while Arm B had 75 patients receiving cisplatin and paclitaxel for three cycles.

Results After 24 weeks of treatment, complete response rates were 53.33% in Arm A and 56.0% in Arm B, with partial response rates of 29.33% and 32.0% respectively. Overall response was 82.66% in Arm A and 88.0% in Arm B, showing no statistically significant difference (p>0.05). Arm A exhibited more anemia, oral mucositis, skin toxicity, and hand- foot syndrome, while Arm B had higher neuropathy. Hematological and non-hematologic toxicities during concurrent chemo-radiotherapy were similar in both arms.

Conclusions Induction chemotherapy with cisplatin and paclitaxel, followed by concurrent chemo-radiotherapy, is equally effective as induction chemotherapy with cisplatin and 5-fluorouracil, followed by concurrent chemo-radiotherapy, in treating advanced head and neck squamous cell carcinoma. However, the former regimen demonstrates significantly fewer toxicities, indicating a safer treatment option.
