Pathological diagnosis and treatment outcome of gastric metastases from small cell lung cancer: A case report

Small cell lung cancer (SCLC) is a type of lung cancer characterized by a rapid disease progression and poor prognosis. Its diagnosis is often accompanied by distant metastasis. A literature review revealed that metastases to the stomach from breast, lung and esophageal cancer are frequently reported. While SCLC is a common pathological subtype of lung cancer, literature on SCLC with gastric metastases is sporadic. The present study reviewed the literature using databases, including PubMed, WanFang Data and China National Knowledge Infrastructure, to analyze the clinicopathological features and outcome of patients with gastric metastases from SCLC. A total of 11 case reports and 6 retrospective studies comprising of 19 cases were compared and analyzed. In addition to the aforementioned studies, a case study describing a patient who survived for 10 months following a diagnosis of SCLC with gastric metastases is presented. The aim of the present study was to increase the understanding regarding the diagnosis and treatment of SCLC gastric metastasis.

Gastric metastases not resulting from direct invasion: Report of 5 cases and review of the literature

Gastric metastases not resulting from direct invasion are rare. Clinically, these patients present with nonspecific symptoms, which easily lead to missed diagnosis or misdiagnosis. MSCT findings of the disease may vary but often have characteristic features, different from those of gastric stromal tumors and primary gastric cancer. Thus, for cancer patients with gastrointestinal symptoms, medical imaging workers should improve the recognition and vigilance of the disease. Careful identification of the characteristic MSCT findings combined with the clinical history can help provide a suggestive diagnosis.
