This minimally invasive approach to treat colon cancer potentially reduces hospitalization time, hastens return to normal activity, and reduces health care costs. Hopefully, all of these favorable outcomes can be achieved without compromising cancer control. At present, however, the issues regarding laparoscopic colectomy are not clear, and prospective studies are necessary to validate that this new procedure is superior to open colectomy. Because cancer control might be compromised by this new procedure, laparoscopic colectomy should not be accepted by the surgical community because of the allure of new technology or the hope that it is equivalent to open colectomy in controlling a curable disease. Rather, a randomized trial of laparoscopic colectomy compared with open colectomy is needed to prove that cancer control is not different and that laparoscopic colectomy is cost-effective.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genetic aspects of multiple endocrine neoplasia types 1 and 2. 1型和2型多发性内分泌肿瘤的遗传方面。

{"title":"Genetic aspects of multiple endocrine neoplasia types 1 and 2.","authors":"K Sandelin,&nbsp;C Larsson,&nbsp;R A Decker","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Multiple endocrine neoplasia (MEN) type 1 is an autosomal, dominantly inherited predisposition to develop neoplastic lesions of the parathyroid glands, the neuroendocrine pancreas-duodenum, and the anterior pituitary. The genetic defect was mapped to the centromeric part of the long arm of chromosome 11 based on studies of somatic deletions in MEN-1-associated tumors and linkage analysis in families in whom the disease is segregated. Combined family and tumor analysis has shown that tumorigenesis in MEN-1 involves loss of the wild-type chromosome, indicating that the putative MEN-1 gene is a tumor suppressor gene. Similar deletions are also seen in a proportion of sporadic parathyroid and pancreatic tumors, suggesting that tumorigenesis involves related mechanisms in both sporadic and familial cases. Based on results from linkage analysis in more than 40 MEN-1 families, predictive testing for MEN-1 using DNA polymorphisms can now be performed with high accuracy. Hence, biochemical screening programs can focus on individuals at risk to identify early signs of tumor development. MEN-2, an autosomal dominant cancer syndrome of variable expressivity, has previously been localized to chromosome 10q11.2 by positional cloning tactics. The RET protooncogene mapping to the MEN2 susceptibility locus has recently emerged as a candidate gene for MEN-2A. RET, a transmembrane receptor protein, has a large glycosylated extracellular domain containing clustered cysteine residues and calcium-binding motifs, a single hydrophobic transmembrane domain, and a cytoplasmic domain with tyrosine kinase catalytic activity. Several germline missense mutations in a codon specifying one of these highly conserved cysteine residues have been detected in patients affected with MEN-2A.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18590384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This condition lacks a known cause and another method of diagnosis, and its treatment is palliative-mechanical, with bypasses, dilation, or orthotopic liver transplantation. Recent progress has been seen in stratifying patients with respect to prognosis. Stratification is important for conducting clinical trials and for predicting which patients should receive a transplant at an earlier, less risky stage in the course of the disease. Expandable metal stents are on trial in patients with benign or malignant strictures. These newer stents seem to be better than polyethylene stents, although their use has not been reported in sclerosing cholangitis. With survival data used as a measuring point, relief of jaundice does not appear to correlate with increased survival. Of concern has been the association of cholangiocarcinoma with sclerosing cholangitis. Cholangiocarcinoma is difficult to recognize clinically and has a negative impact on the results of transplantation.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18588280","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
