Objective: The objective of this study was to evaluate changes in health related quality of life (HRQoL) in patients with metastatic head and neck (H&N) cancer randomized to receive metronomic (methotrexate and celecoxib) or cisplatin chemotherapy.
Methods: Patients older than 18 years, with a Karnofsky Performance score of ≥70, and diagnosed with metastatic, locally advanced inoperable or recurrent head and neck (H&N) cancer not amenable to surgery or radiation were randomized (1:1) to receive metronomic or cisplatin chemotherapy. All patients were recruited from the Tata Memorial Hospital, Mumbai, India. In addition to demographic and baseline clinical characteristics, patients were asked to rate their HRQoL using the EORTC QLQ-C30 and the EORTC QLQ-H&N35 questionnaires (Indian versions) at baseline and at the end of each chemo cycle (every 3 weeks) till the end of study or early termination.
Results: Of the 110 patients screened, 87 agreed to participate in the study. Mean age of the study population was 47.5 years (S.D. ±10.04) for the metronomic group and 47.2 years (S.D. ±9.89) for the cisplatin group. Overall quality of life was not significantly different between the two treatment groups from baseline to end of treatment. However, there was a statistically significant improvement in Pain QLQ-C30 score from baseline to week 3 (OR = 3.14, p = 0.036) and week 6 (OR = 3.33, p = 0.034) in the metronomic arm compared with the cisplatin arm.
Conclusion: In addition to improvements in survival, understanding the impact of treatment options on changes in HRQoL is important as it can aid physicians in making treatment and rehabilitation decisions for patients with advanced inoperable H&N cancer.
