How long does chemotherapy take to work for nasopharyngeal cancer?

Nasopharyngeal cancer starts in the upper part of the throat behind the nose. Chemotherapy may be used before another treatment, alongside radiotherapy, or to control disease that has spread or returned. The purpose of treatment affects how response is judged. Your team may examine the nose and throat, ask about hearing, swallowing, nasal blockage, pain, and neck swelling, and arrange imaging. Symptoms can be influenced by both the cancer and treatment-related inflammation, so they do not always match scan findings.

Attend treatment and review visits even when symptoms are stable. Report mouth soreness, difficulty swallowing, reduced drinking, hearing changes, weight loss, nausea, or worsening pain so the team can provide support. Follow instructions for mouth care and medicines. Ask whether chemotherapy is intended to shrink the tumour before the next treatment, improve symptoms, or control disease, and ask when the response assessment will happen.

Contact the cancer team promptly for trouble breathing, inability to swallow fluids, repeated vomiting, fever or chills, new confusion, heavy bleeding, sudden facial weakness, or rapidly worsening headache. These symptoms need medical assessment during treatment and should not be interpreted simply as a sign that chemotherapy is or is not working.

What is the goal of chemotherapy in my plan? Which scan or examination will show response? How might chemotherapy affect the timing of radiotherapy? Which swallowing or hearing changes should I report immediately?
