- W2051954497 abstract "<i>Background:</i> Pancreatic cancer is the fifth leading cause of cancer-related death worldwide. Among patients treated with surgery alone, liver metastasis occurs in up to 50%, peritoneal recurrence in 25%, and local recurrence occurs in 50–80% of all patients who underwent resection. Even after a macroscopically curative resection, tumour cells might be observed by microscopy at one or more edges of the resected specimen in 20–51% (R-1) which might account for the high local recurrence. <i>Aim of the Study: </i>An analysis was performed in 54 patients who underwent an irradical resection (R-1 and R-2) for pancreatic cancer. 33 patients were treated with chemoradiotherapy. To evaluate the effect of therapy on survival and recurrence, this group was retrospectively compared to a group of 21 patients that did not receive chemoradiotherapy. <i>Methods:</i> Radiotherapy consisted of 50 Gy external upper abdomen radiation in two courses of 3 weeks, concomitant with intravenous 5-FU 25 mg/kg/24 h continuously on the first 4 days of each treatment course. Follow-up was performed mainly by CT scanning and occasionally by US and was completed for all but 1 patient. <i>Results:</i> The treatment protocol was completed in all patients without complications. Local recurrence was found in 6 (18%) patients in the group of patients who received adjuvant therapy versus 16 (48%) patients in the group that did not receive adjuvant therapy (p = 0.001). The median survival time for the treated group was 12.8 vs. 13.7 months in the group that did not receive chemoradiotherapy (p = 0.9). Three (9%) patients are still alive 140, 88 and 70 months after receiving surgery and adjuvant treatment. <i>Conclusion: </i>Adjuvant chemoradiotherapy clearly gives a significant better local control. However, treatment with 5-FU and radiotherapy does not improve survival due to distant metastases. This therapy probably prolongs survival in only a few patients. More effective treatment methods have to be designed to prevent metastatic disease and improve survival." @default.
