How effective is chemotherapy for head and neck cancer?

Chemotherapy medicines travel through the bloodstream, so they can reach cancer cells beyond the original area. In head and neck cancer, treatment may be given before local treatment to reduce tumour size, together with radiotherapy to make cancer cells more sensitive to radiation, or after treatment when the team is trying to lower the chance of remaining disease. For some people it is used to control cancer that cannot be removed completely. The response is assessed with examination, imaging, and sometimes tissue or laboratory tests. A smaller tumour is one sign of benefit, but preserving swallowing, breathing, speech, or other functions can also shape the treatment goal.

Your oncology team considers the cancer’s exact site, stage, cell features, general health, kidney and hearing function, nutrition, and whether surgery or radiotherapy is planned. Ask how the proposed medicines fit with the wider plan and how response will be checked. Keep a record of medicines, report changes in eating or drinking early, and seek help from dietetics, speech and swallowing specialists, or dental services when offered. The treatment course may be divided into cycles with recovery time between them.

Contact your cancer team promptly for a fever, shaking chills, sudden breathlessness, chest pain, confusion, uncontrolled vomiting, or inability to keep fluids down. New difficulty breathing or a rapidly worsening problem with swallowing needs urgent assessment. Mouth sores, diarrhoea, severe weakness, bleeding, or reduced urine can also need same-day advice during treatment.

Which goal does chemotherapy have in my treatment: shrinking the cancer, helping radiotherapy, reducing residual disease, or controlling symptoms? How will you measure my response, and what alternatives would be considered if the tumour does not respond? Which side effects should trigger a same-day call?
