What Did the Pandemic Teach Us About Palliative Radiation in Head and Neck Cancer?
Aim: To assess the feasibility and efficacy of palliative radiotherapy dose regimens for patients with locally advanced head and neck cancer. Methods: Fifty patients of previously untreated, inoperable, stage IVA and IVB squamous cell carcinoma of the head and neck, deemed unfit for radical treatment, were included in the study from May 2020 to June 2020. Two palliative radiotherapy regimens were used. First was a single fraction radiation with 8 Gy for patients with limited life expectancy and poor performance status, which was repeated after 4 weeks in case of good symptom relief. The second regimen was used for patients with good performance status and consisted of fractionated radiation with 30 Gy in 10 fractions over 2 weeks, which was followed by supplementary radiation with 25 Gy in 10 fractions over 2 weeks in patients with good symptomatic response at 2 weeks. Symptoms were assessed at baseline and at the end of 4 weeks after treatment completion using the numerical rating score. Patients were followed up for a median of 4.5 months and assessed for symptom control and overall survival. Results: Forty-eight patients completed treatment and were included for analysis. Of the 24 patients who received single fraction radiation, 13 (54.2%) were given the second dose. Improvement in pain and dysphagia were reported in 57.9% and 60% patients, respectively. A total of 55.5% noted decrease in size of the neck node. Twenty-four patients received fractionated radiation and 15 (62.5%) were given the second course after 2 weeks. Relief in pain and dysphagia was reported in 68.2% and 63.6% patients, respectively. There were no grade 3/4 toxicities. Symptom control lasted for at least 3 months in 30% of the patients who received single fraction radiation and 54.2% of the patients who received fractionated radiation. The estimated 6-month overall survival of the entire cohort was 51.4%. Conclusion: Judicious use of palliative radiation in advanced incurable head and neck cancers provides effective and durable symptom relief and should be used after careful consideration of patient prognosis, logistics of treatment, and goals of care.
