Bengaluru, Sep 13 : Low dose immunotherapy can be a hope for patients with head and neck cancer by reducing tumours and side effects, according to a pilot study led by doctors at a private hospital here. The successful pilot study on Low Dose Immunotherapy Nivolumab with neoadjuvant chemotherapy has demonstrated remarkable efficacy and is highly cost-effective, providing an economical therapy option without additional side effects, said doctors at Healthcare Global Cancer Hospital (HCG) Bengaluru on Wednesday. "Cancer is fast becoming a chronic disease, and a sea change has occurred in how we stage cancer as we adopt a multi-disciplinary approach to treatment,' said Dr B S Ajaikumar, Executive Chairman of HCG, in a statement. "This study has the potential to be a game-changer in the sphere of head and neck cancer treatment," he added. HCG studied twelve patients of the age group 54 to 76 who experienced significant tumour reduction of over 90 per cent, providing an economical and side-effect-free therapy through low-dose immunotherapy. During the study, patients were administered with 40 mg doses every two weeks, as opposed to the full dose of 3 mg per kg of body weight with standard neoadjuvant chemotherapy, combined with low-dose Nivolumab immunotherapy. 'This study presents a cost-effective solution without compromising the quality of care. This approach not only delivers promising clinical results but also in a manner that is highly economical for patients," said Dr Satheesh C T, Consultant - Medical and Hemato Oncology, Director of Clinical Trials, HCG Cancer Hospital Bangalore.
