Head and neck cancer: Additional chemotherapy increases survival rate for older patients
Source: www.dental-tribune.com Author: Franziska Beir, Dental Tribune International Head and neck cancer is the sixth most common cancer worldwide and results in approximately 450,000 deaths per year. As a result of demographic change, the proportion of older patients with this type of cancer is continuously increasing, and these patients are under-represented in clinical trials. The question of whether older patients should be treated with chemotherapy or drug therapy—in addition to radiotherapy—can cause controversy, and the association with higher survival rates has remained unclear. A large-scale international study involving University of Leipzig Medical Center and 12 other university hospitals has now proved the effectiveness of this combined treatment. Cancer treatment for older patients is more individualised compared with that for younger patients, owing to an increasing prevalence of frailty, comorbidities and a higher vulnerability to chemotherapy-related toxic effects. Standardised treatment for head and neck cancer either entails surgical removal of the tumour followed by radiotherapy or organ-preserving radiotherapy in combination with chemotherapy. The latter treatment is especially controversial, and there has been a lack of clinical data to determine the best option. The study involved 12 university hospitals in Europe and the US. The researchers analysed data from 1,044 older patients (65 years or older) with head and neck cancer of the oral cavity, pharynx or larynx. Between 2005 and 2019, 234 of these patients were treated with radiotherapy alone and 810 with radiotherapy in combination with either chemotherapy (677) or an alternative drug therapy with an antibody against a growth [...]
