Pancreatic cancer, one of the diseases of the elderly, has dismal prognosis, demanding major surgery with high risk and life quality problems, especially in the elderly. Therefore, treatment selection, whether or not to undergo surgery, preoperative risk assessment, and perioperative management of the elderly are becoming critical issues. Although the elderly are expected to have higher morbidity and mortality and lower long-term survival outcomes, surgery is becoming safer over time. Appropriate surgical indication selection, patient-centered decision-making, adequate prehabilitation and postoperative geriatric care are expected to improve surgical outcomes in the elderly. Surgeons must have the concept of geriatric care, and efforts based on institutional systems and academic societies are required. If well selected and prepared, the same surgical principle as non-elderly patients can be applied to elderly patients. In this paper, the surgical treatment of elderly patients with pancreatic cancer is reviewed.

The purpose of this study was to determine the clinical significance of nodal micrometastasis detected by immunohistochemistry in patients that had undergone curative surgery for pancreatic cancer. Between 2005 and 2006, a total of 208 lymph nodes from 48 consecutive patients with pancreatic cancer that had undergone curative resection were immunostained with monoclonal antibody against pan-ck and CK-19. Micrometastasis was defined as metastasis missed by a routine H&E examination but detected during an immunohistochemical evaluation. Relations between immunohistochemical results and clinical and pathologic features and patient survival were examined. Nodal micrometastases were detected in 5 (29.4%) patients of 17 pN0 patients. Nodal micrometastasis was found to be related to tumor relapse (P = 0.043). Twelve patients without overt nodal metastasis and micrometastasis had better prognosis than 5 patients with only nodal micrometastasis (median survival; 35.9 vs 8.6 months, P < 0.001). The Cox proportional hazard model identified nodal micrometastasis as significant prognostic factors. Although the number of patients with micrometastasis was so small and further study would be needed, our study suggests that the lymph node micrometastasis could be the predictor of worse survival and might indicate aggressive tumor biology among patients undergoing curative resection for pancreas cancer.
