Chemoradiation prior to pancreaticoduodenectomy ensures that all patients who undergo resection complete multimodality therapy, avoids resection in patients with rapidly progressive disease, and allows radiation therapy to be delivered to well-oxygenated cells before surgical devascularization. Twenty-eight patients with cytologic or histologic proof of localized adenocarcinoma of the pancreatic head received preoperative chemoradiation (fluorouracil, 300 mg/m2 per day, and 50.4 Gy) with the intent of proceeding to resection; all 28 completed this preoperative therapy. Hospital admission because of gastrointestinal toxic effects was required in nine patients, yet no patient experienced a delay in operation. Restaging was performed 4 to 5 weeks after completion of chemoradiation, and five patients were found to have metastatic disease; the 23 patients without evidence of progressive disease underwent laparotomy. At laparotomy, three patients were found to have unsuspected metastatic disease, three patients had unresectable locally advanced disease, and 17 patients were able to undergo pancreaticoduodenectomy. One perioperative death resulted from myocardial infarction, and perioperative complications occurred in three patients. Histologic evidence of tumor cell injury was present in all resected specimens. Our results suggest that pancreaticoduodenectomy can be performed with a low incidence of complications after chemoradiation for localized adenocarcinoma of the pancreas.
Objectives To determine the characteristics of popular breast cancer related websites and whether more popular sites are of higher quality. Design The search engine Google was used to generate a list of websites about breast cancer. Google ranks search results by measures of link popularity-the number of links to a site from other sites. The top 200 sites returned in response to the query "breast cancer" were divided into "more popular" and "less popular" subgroups by three different measures of link popularity: Google rank and number of links reported independently by Google and by AltaVista (another search engine). Main outcome measures Type and quality of content. Results More popular sites according to Google rank were more likely than less popular ones to contain information on ongoing clinical trials (27% v 12%, P = 0.01 ), results of trials (12% v 3%, P = 0.02), and opportunities for psychosocial adjustment (48% v 23%, P < 0.01). These characteristics were also associated with higher number of links as reported by Google and AltaVista. More popular sites by number of linking sites were also more likely to provide updates on other breast cancer research, information on legislation and advocacy, and a message board service. Measures of quality such as display of authorship, attribution or references, currency of information, and disclosure did not differ between groups. Conclusions Popularity of websites is associated with type rather than quality of content. Sites that include content correlated with popularity may best meet the public's desire for information about breast cancer.
One hundred seventy-four evaluable patients with noninflammatory Stage III (both operable and inoperable) breast cancer were treated with a combined modality strategy between 1974 and 1985. All patients received combination chemotherapy with 5-fluorouracil, Adriamycin (doxorubicin), and cyclophosphamide (FAC) as their initial form of therapy. After three cycles of chemotherapy, local treatment in the form of a total mastectomy with axillary dissection, or radiotherapy, or both, was completed. Subsequently, adjuvant chemotherapy was continued. There were 48 patients with Stage IIIA, and 126 patients with Stage IIIB disease. A complete remission was achieved in 16.7% of the patients, and 70.7% achieved a partial remission after the initial three cycles of FAC. The complete response rate was higher for patients with Stage IIIA, than for patients with Stage IIIB disease. All but six of the 174 patients treated were rendered disease-free after induction chemotherapy and local treatment. The median follow-up of this group of patients is 59 months. The 5-year disease-free survival rates were 84% for patients with Stage IIIA, and 33% for patients with Stage IIIB disease. The 5-year survival rate for, patients with Stage IIIA was 84%, and for patients with Stage IIIB 44%. At 10 years, 56% of patients with Stage IIIA and 26% of patients with Stage IIIB disease are projected to be alive. Younger patients, and those with estrogen receptor-positive tumors, had a trend for better survival than older patients and those with estrogen receptor-negative tumors. The quality of response to induction chemotherapy correlated prominently with prognosis, as did compliance with treatment. Twenty-six patients (15.3%) had locoregional recurrence. This multidisciplinary approach to locally advanced breast cancer rendered most patients disease-free and produced an excellent local control rate. Modifications of this treatment strategy may result in further improvement of survival rates.
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.
