Approach to patients with pancreatic cancer without detectable metastases

The poors outcomes associated with pancreatic cancer clearly reflect the advanced stage of disease at diagnosis for most patients. Through this lens, it is easy to lose sight of the fact that roughly 50% of patients with pancreatic cancer have no clinically detectable metastases at presentation. Herein, we discuss how patients with localized pancreatic cancer are currently managed. The primary goal of care for patients with resectable and borderline-resectable tumors is cure, facilitated by achieving margin-negative resection of the primary disease and delivering effective adjuvant and/or neoadjuvant therapy. For patients with locally advanced disease, the focus is on limiting local progression and outgrowth of metastatic disease and maintaining quality of life. Although it was once a centerpiece of therapy for localized pancreatic cancer, the value and place of radiation therapy in the treatment algorithm is now under increased scrutiny. In contrast, given its value as demonstrated in multiple prospective trials, chemotherapy is an established part of the treatment paradigm for all patients. With the demonstration that cytotoxic combinations such as fluorouracil, leucovorin, irinotecan, and oxaliplatin as well as gemcitabine/nab-paclitaxel are active in the metastatic setting, these agents are now being studied in patients with localized disease. The neoadjuvant setting provides a particularly favorable setting for evaluating new systemic strategies. Given the array of new targets, including immunomodulatory approaches, there is reason for optimism that we can markedly improve survival for all patients with pancreatic cancer and enter an era in which surgery with curative intent actually fulfills this goal on a much more regular basis.
