CAPOX chemotherapy for stage 3 cancer

The aim is to treat cancer cells that may remain after the tumour and nearby lymph nodes have been removed. Whether CAPOX is appropriate depends on the pathology findings, general health, kidney function and the balance between likely benefit and side effects.

Capecitabine is taken by mouth and is converted in the body into an active chemotherapy medicine. Oxaliplatin is given into a vein. Both interfere with cancer-cell growth, but they have different side-effect patterns.

Stage 3 means cancer cells have reached nearby lymph nodes, without defining distant spread. Treatment is arranged in cycles with treatment days and recovery time. Blood tests before treatment help the team check blood-cell counts and organ function.

Take capecitabine exactly on the schedule supplied by the oncology team. Do not double a missed dose. Keep an updated list of prescription medicines, supplements and non-prescription products because interactions may change how treatment is given.

Cold air, drinks or objects can trigger tingling or throat discomfort after oxaliplatin, so follow the team's advice about avoiding cold exposure. Report diarrhoea, sore mouth, painful or peeling hands and feet, numbness, poor intake or vomiting early; dose delays or supportive medicines may prevent these problems from worsening.

Use the oncology emergency number immediately for a fever, shaking chills, new breathlessness, chest pain, confusion, uncontrolled diarrhoea or vomiting, inability to drink, unusual bleeding, or a rapidly spreading rash. Chemotherapy can reduce infection-fighting blood cells, and an infection may become serious before you feel very unwell.

Call emergency services for severe breathing difficulty, collapse, facial or throat swelling, or chest pressure. Do not wait for the next clinic visit when symptoms are sudden or rapidly worsening.

Ask what the surgical pathology showed, what treatment is intended to achieve, how kidney function affects capecitabine dosing, and which symptoms require stopping tablets until you receive advice. It is also useful to clarify fertility, work, driving, vaccinations and who to call outside clinic hours.
