Background: Lung cancer represents the second leading cause of death in US and the high mortality rate could be related to the diagnosis, usually, performed in an advanced metastatic stage. Gastrointestinal metastases from non-small cell lung cancer, are extremely rare and only few cases complicated by digestive haemorrhage and/or perforation have been reported in literature. Material and methods: We report two cases of gastrointestinal metastases and their rare clinical onset with haemorrhage and perforation of the digestive tract. Both patients were admitted in an emergency setting. The first case was a 59-year-old man complained of abdominal pain and massive gastrointestinal haemorrhage. An upper gastrointestinal endoscopy revealed an ulcerated gastric mass and an emergency CT-scans showed a right lung mass with biopsy conclusive for a large cell lung cancer. The second case was a 62-year-old man with abdominal pain and shock due to gastrointestinal bleeding. He was submitted to an emergency CT-scan showing two lung nodules (1.0 and 3.5 cm of diameter) as well as widespread metastases, intraperitoneal free air and fluids. Results: Both patients were surgical managed in emergency and pathology revealed the metastatic origin from an unknown large-cell lung cancer and a rare lung adenocarcinoma in the second one. Conclusions: Despite the rare clinical condition, in patients with a diagnosis of lung cancer managed in emergency for gastrointestinal complication, gastrointestinal metastases should be taken into account, and referred to the primary disease in order to tailor the best approach.

Abstract

Background: Lung cancer represents the second leading cause of death in US and the high mortality rate could be related to the diagnosis, usually, performed in an advanced metastatic stage. Gastrointestinal metastases from non-small cell lung cancer, are extremely rare and only few cases complicated by digestive haemorrhage and/or perforation have been reported in literature. Material and methods: We report two cases of gastrointestinal metastases and their rare clinical onset with haemorrhage and perforation of the digestive tract. Both patients were admitted in an emergency setting. The first case was a 59-year-old man complained of abdominal pain and massive gastrointestinal haemorrhage. An upper gastrointestinal endoscopy revealed an ulcerated gastric mass and an emergency CT-scans showed a right lung mass with biopsy conclusive for a large cell lung cancer. The second case was a 62-year-old man with abdominal pain and shock due to gastrointestinal bleeding. He was submitted to an emergency CT-scan showing two lung nodules (1.0 and 3.5 cm of diameter) as well as widespread metastases, intraperitoneal free air and fluids. Results: Both patients were surgical managed in emergency and pathology revealed the metastatic origin from an unknown large-cell lung cancer and a rare lung adenocarcinoma in the second one. Conclusions: Despite the rare clinical condition, in patients with a diagnosis of lung cancer managed in emergency for gastrointestinal complication, gastrointestinal metastases should be taken into account, and referred to the primary disease in order to tailor the best approach.
