Chemotherapy and radiation therapy to treat head and neck cancer increases the half-life of these patients.
When this type of cancer receives only radiotherapy as treatment, it has a mean survival of 1.1 years, compared to the 2.2 years it would have if chemotherapy and radiotherapy were used simultaneously.
This investigation was carried out in different groups of patients, indicating that chemotherapy administered at the same time as radiotherapy decreased both the rate of deaths and chemotherapies received in patients not surgically treated.
On the contrary, cancer patients who had already undergone surgery did not benefit from the addition of chemotherapy to traditional treatment, which is radiotherapy.
