Improved survival in small pancreatic cancer

Although the incidence of pancreatic cancer is relatively low compared with other tumors (2.4%), the death rate is high. Tumor detection and treatment at an early stage is necessary to improve the poor prognosis of patients, as is demonstrated by some reports showing a 5-year survival rate varying between 19 and 41% for patients undergoing radical pancreatectomy with the highest survival in patients with small tumors.

In our study we retrospectively reviewed the histologic and demographic data of 596 patients who were admitted to the surgical units of the Careggi Hospital (University of Florence-AOC of Florence) between 1988 and 1994 with the incoming diagnosis of pancreatic cancer.

Results are reported as the mean +/- standard deviation. The postoperative survival rate was calculated by the Kaplan-Meier method and statistical analysis was performed by the log rank test (significance p < 0.05). 247 patients had surgery, 110 with a curative intent. Postoperative mortality was 5.45%. The crude 5-year survival rate for patients who underwent curative surgery was 16.36% (18 patients), but for patients with small lesions confined to the pancreas (T1N0M0, 29 patients) this was even 31.03% (9 patients; p < 0.01, chi2 test).

Our results indicate that it seems reasonable to consider these cancers as 'small', with survival reported in literature from 35 to 41%, so they probably represent the only curable condition at the present time.
