Extended operation for non-small-cell lung cancer invading into the liver.
Direct invasion of a lung cancer into the liver is rare. Here we report a case with a non-small-cell lung cancer invading through the diaphragm into the liver. A 77-year-old woman was admitted to our hospital with a complaint of right chest pain. Chest X-ray showed a 10-cm shadow in the right lower lung field. Chest CT demonstrated a large heterogeneous tumor located in the right lower lobe of the lung. Chest MRI revealed the tumor directly invading through the diaphragm into the liver. Bronchoscopic biopsy revealed squamous cell carcinoma. Surgical resection was performed to prevent intrapulmonary rupture of the necrotic contents. A right lower lobectomy was performed with partial resection of the diaphragm, liver and chest wall. Marlex mesh was used to reconstruct the diaphragm and chest wall. The patient was discharged on the 23rd postoperative day without complications, but died 4 months later from bilateral pulmonary metastases. Invasion to the diaphragm and liver may increase the risk for hematological spread. Although there are limited reports on treatment options, combined resection of the liver should be considered in the case of non-small-cell lung cancer invading the liver, particularly in c-N0M0 case.
