Lung cancer spread to the stomach and life expectancy

Stomach metastasis means cells from the lung cancer have travelled to the stomach; it is not the same as a new primary stomach cancer. It is uncommon, and symptoms may be absent. Possible symptoms include upper abdominal discomfort, nausea, vomiting, early fullness, reduced appetite, black stools, or bleeding.

Doctors may use scans, endoscopy, and a biopsy to confirm the cause of a stomach lesion. They also assess the lungs and other organs, the cancer subtype, molecular features, nutrition, and how well you are functioning. These details help the team discuss goals and options without reducing your situation to a single time estimate.

Treatment may aim to control cancer throughout the body, relieve a stomach symptom, or both. Options can include chemotherapy, immunotherapy, targeted treatment when tumour testing identifies a suitable change, radiotherapy for selected symptoms, or an endoscopic or surgical procedure for bleeding or blockage. Genomic tumour profiling may be relevant to treatment selection.

Ask how the team will manage appetite, pain, nausea, constipation, and hydration. Palliative care can work alongside cancer treatment to support comfort and daily function. If you want a clearer prognosis discussion, ask what factors are helping or limiting treatment and when the team will reassess the plan.

Seek urgent medical help for vomiting blood, black or bloody stools, severe or persistent abdominal pain, repeated vomiting, fainting, marked weakness, inability to keep fluids down, or new confusion. Severe breathlessness, chest pain, or sudden collapse also needs emergency care. Do not wait for a routine appointment when bleeding or dehydration may be present.

How was stomach involvement confirmed? Are there other areas involved? What is the goal of each proposed treatment? Could tumour profiling change the options? What symptoms suggest bleeding or blockage? Who should I call outside clinic hours?
