OBJECTIVE To evaluate the results of surgical treatment for lung carcinoid tumor. PATIENTS AND METHOD The medical records of 62 patients who underwent surgical intervention for lung carcinoid tumor between May 1985 and October 2000 were reviewed. RESULTS Fifty-two patients had typical carcinoid tumors and 10 had atypical carcinoid tumors. Hilar or mediastinal lymph node metastases were pres...

Carcinoid tumors of the rectum are uncommon tumors [1]. However, recent report shows that the number of reported cases increases rapidly in both Japanese and non-Japanese series [2], probably due to the constant increase number of colonoscopic examination. The rectum is the most common site of gastrointestinal carcinoid tumors in Japan and the third most common site in American-European countri...

Carcinoid tumors are rare neuroendocrine tumors that arise from neural crest amine precursor uptake decarboxylation cells. Most of carcinoid tumors originate in the midgut. The vasoactive secretory products of carcinoid tumor upon metastasis to liver reach systemic circulation as they bypass the metabolism by liver. 50% of patients with carcinoid syndrome eventually develop carcinoid heart dise...

Gastric carcinoid tumors are rare tumors that originate from gastric enterochromaffin-like cells in the oxyntic mucosa and constitute 3.2-4% of all carcinoid tumors. Herein, outcome of a single institution experience with gastric carcinoid tumors were evaluated retrospectively. The patients with gastric carcinoid tumors were analyzed with respect to their presenting signs and symptoms, serum ga...

BACKGROUND: Carcinoid tumors are the most frequently encountered endocrine tumors of the gastrointestinal tract. They are most often found in the appendix, although they can arise in any location of the gut. Carcinoid tumors may secrete a variety of bioactive substances, which can cause the complex of symptoms associated with the carcinoid syndrome. METHODS: The authors reviewed the pathology, ...

There are three main areas of origin for carcinoid tumors: foregut carcinoid tumours start in the lungs, bronchi, or stomach; midgut carcinoid tumours start in the small intestine, appendix, or proximal large bowel; and hindgut carcinoid tumours start in the distal colon or rectum3. The appendix is the most common site of carcinoid tumors, followed by the rectum, ileum, lungs, bronchi, and stom...

We have previously demonstrated that gastric and intestinal endocrine cell (End-cell) marker expression is important for assessment of the histogenesis of endocrine cell tumors. However, the End-cell phenotypes of carcinoid tumors in the rectum remain largely unclear. We therefore examined marker expression of rectal carcinoid tumors. We evaluated 20 rectal carcinoid tumors (as well as 8 from t...

Carcinoid tumors are slow-growing tumors originating in the neuroendocrine cells, and occur most frequently within the gastrointestinal tract. Although the liver is the most common site for metastatic carcinoid tumors, primary hepatic carcinoid tumors are exceedingly rare and reports of the imaging findings have been very scarce. We herein report imaging findings with an emphasis on magnetic re...

PURPOSE This study aimed to investigate the expression of the ErbB family of receptor tyrosine kinases in pulmonary typical carcinoid and atypical carcinoid tumors and to understand the role of epidermal growth factor receptor (EGFR) signaling in pulmonary carcinoid tumor proliferation. EXPERIMENTAL DESIGN Surgically resected typical carcinoid (n = 24) and atypical carcinoid (n = 7) tumor tis...
