Insufflation with CO2 during colonoscopy results in less pain during and after the examination. Because of better tolerance, colonoscopy with CO2 insufflation might gain wide acceptance in the community to be used as a screening tool.
Gemcitabine is active in previously untreated small cell lung cancer in doses which produce little toxicity. Combination studies of Gemcitabine with other agents active in this disease are warranted.
Primary small cell carcinoma of the esophagus (SmCC) is an uncommon aggressive tumor characterized by early systemic dissemination and poor prognosis, regardless of the methods of treatment. The optimal treatment strategy remains uncertain. A retrospective study was conducted to review the results of non-operative treatment for patients with limited and metastatic esophageal SmCC. Between 1993 and 2003, 10 patients were diagnosed to have primary esophageal SmCC in our institution. Six of them had disseminated diseases, whereas the other four had limited disease upon diagnosis. All patients were managed non-operatively by either chemotherapy and/or radiotherapy. The overall median survival was 8 months (range, 2-62 months). The survival was 4-62 months for patients with limited disease, whereas it was 2-10 months for patients with disseminated disease at initial diagnosis. In summary, the current study demonstrated satisfactory palliation could be achieved with chemo-radiation for patients with limited disease; however, the ultimate role of primary chemo-radiation for esophageal SmCC must await results from randomized trials.
Cisplatin plus gemcitabine is a well-tolerated, effective, and convenient induction chemotherapy regimen and warrants further studies to confirm its benefit in advanced NPC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
