Background: Head and neck cancers are attributed to be the most common type of malignancy in the developing countries with most cases presenting in advanced stage. This pilot study was performed to evaluate the effect of an accelerated hypofractionated 4 days schedule (octa shot) in providing palliation to such advanced cases of head and neck cancer. Materials and Methods: Twenty-two patients with advanced (Stage VIB-IVB) squamous cell carcinoma of head and neck region were enrolled in the study. All these patients were planned for radiotherapy at Cobalt Unit with a fractionation schedule of 3.5 Gy/fraction, 2 fractions/day with 6 h interval between two fractions, for four days (28 Gy/8Fr/4 days). Patients were reviewed at 2 and 4 weeks to assess change in tumor size, any symptomatic relief, or toxicity. The tumor response, dermal, and mucosal toxicities were assessed using WHO criteria. Results: Median age of these 22 patients (17M male + 5F female) in the study was 59.8 years. After completion of radiotherapy, first response evaluation done at 15th day showed ≥50% objective response in 14 patients. At 1 month, this response increased to ≥75% in 16 patients and 50%–75% in three patients. None of the patients had disease progression. Improvement in symptoms was reported with respect to pain and dysphagia by patients subjectively. Only two patients reported Grade III mucositis; remaining patients had mucositis and dermatitis up to Grade II. Conclusion: The study concludes that this "octa shot" is an effective palliative radiotherapy schedule. With a decreased duration of hospital stay, it is also favorable for outpatients.
