As undergoing pancreaticoduodenectomy at the johns hopkins hospital between 1970 and 1994 were analyzed (the last large integer resections were performed between march 1991 and april 1994). This is the largest single-institution experience reported to date. Results: the overall postoperative in-hospital mortality rate was 5%, but has been 0. 7% for the last 149 patients. The actuarial 5-year survival for all 201 patients was 21%, with a median survival of 15. 5 months. what's better viagra viagra There were 11 5-year survivors. is 200 mg of viagra too much Patients resected with negative margins (curative resections: n = 143) had an actuarial 5-year survival rate of 26%, with a median survival of 18 months, whereas those with positive margins (palliative resections; n = 58) fared significantly worse, with an actuarial 5-year survival rate of 8% and a median survival of 10 months (p < 0. 0001).

Multivariate analyses indicated the strongest predictors of long-term survival were diploid tumor dna content, tumor diameter < 3 cm, negative nodal status, negative resection margins, and decade of resection. buy viagra Conclusions: the survival of patients with pancreatic adenocarcinoma treated by pancreaticoduodenectomy is improving. generic viagra Aspects of tumor biology, such as dna content, tumor diameter, nodal status and margin status, are the strongest predictors of outcome. viagra 2.5 mg price Pmid: 7794076 [pubmed - indexed for medline] pmcid: pmc1234702 free pmc article publication types, mesh terms, substances, grant support publication types clinical trial research support, u. discount generic viagra mg S. viagra no prescription Gov't, p. viagra 2.5 mg price H.
