BACKGROUND: Concurrent chemoradiation with 3 weekly cisplatin (100 mg/m2) is the standard of care for locally advanced head and neck cancer. However, this regimen has been shown to be associated with lesser compliance and higher toxicities. Hence, there is a need to explore alternative concurrent cisplatin regimens.
OBJECTIVES: The objective of this study was to compare the efficacy and toxicities of 3 weekly cisplatin (100 mg/m2) with weekly cisplatin (40 mg/m2) concurrently with radiation in patients with locally advanced head and neck cancer.
PATIENTS AND METHODS: This phase IIb trial randomized 56 patients with Stage III and IV squamous cell carcinoma of oropharynx, hypopharynx, and larynx to Arm A or Arm B. Arm A received cisplatin 100 mg/m2 3 weekly and Arm B received cisplatin 40 mg/m2 weekly concurrently with radiation. The primary end point was disease-free survival (DFS) and secondary end points were overall survival (OS) and acute toxicity. DFS and OS were estimated using Kaplan-Meier method, and log-rank test was used to assess the difference in these distributions with respect to treatment.
RESULTS: The 2-year DFS in Arm A and Arm B was 64.5% and 52.8%, respectively (P = 0.67). The OS at 2 years was 71% and 61.1% in Arm A and Arm B, respectively (P = 0.61). There were no significant differences in acute hematological, renal, or mucosal toxicities between the two arms.
CONCLUSION: This study showed a nonsignificant improvement in DFS and OS in the 3 weekly cisplatin arm over the weekly arm with comparable toxicities. The trial is registered with Clinical Trial Registry of India (CTRI registration number: CTRI/2013/05/003703, URL-http://ctri.nic.in).
