Gastrointestinal Surgery of Neuroendocrine Neoplasms

2015
Surgery is the only treatment that may cure the patient with gastroenteropancreatic (GEP) neuroendocrine neoplasms (NENs) and should always be considered as the first-line treatment if radical resection can be achieved. Even in cases where radical surgery is not possible, palliative resection may be performed to reduce local or hormone-induced symptoms

Overt gastrointestinal bleeding in haematologic neoplasms

Digestive and Liver Disease, 2005
Patients with acute leukaemia suffer from various haemorrhages, most frequently due to thrombocytopenia. We could not reach any information regarding the frequency of gastrointestinal bleeding in acute leukaemia and decided to search this complication in patients with acute and chronic leukaemias and myeloproliferative disorders, retrospectively.During

NEOPLASMS OF THE UPPER GASTROINTESTINAL TRACT

Radiologic Clinics of North America, 1994
Neoplasms of the upper gastrointestinal tract are generally detected by barium studies or endoscopy. Computed tomography remains the primary imaging modality for staging. Magnetic resonance imaging and endoscopic ultrasonography may also play an increasing role in evaluating these tumors.

Gastrointestinal lymphoid neoplasms.

Seminars in diagnostic pathology, 1987
Primary gastrointestinal lymphomas (PGLs) are the most frequent extranodal non-Hodgkin's lymphomas and involve stomach more commonly than small bowel in Western countries. PGLs need to be differentiated from a variety of tumor-like hyperplastic lymphoid lesions; this may be facilitated by immunotyping of lymphoid cells.

Gastrointestinal Stromal Tumors and Extra-Gastrointestinal Tract Neoplasms

Southern Medical Journal, 2010
Gastrointestinal stromal tumor (GIST) is a relatively uncommon and predominantly sporadic tumor of the gastrointestinal tract (GIT). Infrequently, it can be associated with other neoplasms, notably GIT carcinomas and, rarely, extra-gastrointestinal tumors. Whether this concomitant occurrence is a causal association or a coincidence is not yet resolved,

Gastrointestinal Neoplasms in von Recklinghausen's Disease

Archives of Surgery, 1966
NEUROFIBROMATOSIS originally described by von Recklinghausen in 1882 is often depicted as a chronic progressive hereditary disease characterized by pigmentation of the skin, cutaneous lesions, and numerous tumors developing in association with elements of both the central and peripheral nervous systems. This entity is often complicated by abnormalities

Plasminogen Activators and Gastrointestinal Neoplasms

Scandinavian Journal of Gastroenterology, 1989
Plasminogen activators are involved in the growth, the local invasion, and the metastatic spreading of cancer. In particular, the urokinase type of plasminogen activator (u-PA) is produced and secreted by adenocarcinomas of the gastrointestinal tract.

Gastrointestinal tract neoplasms with dependent hypoglycemia

The American Journal of Surgery, 1974
Abstract A seventy-four year old man with primary adenocarcinoma of the colon and hepatic metastases was found to have severe hypoglycemia. A recently developed test using glucagon excluded the possibility of hyperinsulinism and deficient hepatic storage of glycogen as mechanisms for hypoglycemia.

[Artificial gastrointestinal tract in gastrointestinal neoplasms].

Onkologie, 1979
From 1970 to 1977 an artificial gut was used in 1350 patients suffering from gastrointestinal cancer. This type of prolonged intestinal assistance was recognized to be an important adjuvant in anticancer therapy with indications prior to, during and following the traditional course of treatment.
