Developments in pancreatic cancer surgery

Abstract

Pancreatic cancer surgery, with one of the worst prognoses in oncology, is a challenge to the surgical community. Centralization of pancreatic surgery has led to the foundation of high-volume centers, thereby greatly facilitating the successful performance of more radical approaches. This review spotlights on recent advances in surgical approaches to pancreatic cancer and the risks and benefits of vascular reconstruction to improve resectability. Surgery being the only modality to achieve cure, multivisceral and vascular resections are being incorporated to improve dismal operability rates of < 10%. Great leaps have been made in neoadjuvant and adjuvant treatment, as targeted and specific chemotherapeutic agents are being continually added. The concept of borderline and locally advanced pancreatic tumors and the use of neoadjuvant chemorad has extended the indications of oncological resection in such tumors. Venous resections are being routinely performed so as to facilitate en bloc removal of tumors, while arterial resections, owing to the increased morbidity and mortality, are offered to highly selective cases. New techniques like the triangle operation and periarterial divestment have opened new viable surgical options. Although laparoscopic approach is time consuming, it offers reduced operative blood loss and a shortened hospital stay at specialized centers. Robotic surgery may produce better results in patients needing vascular resection and reconstruction, but the expenses involved and limited availability are major deterrents. Advanced techniques of surgical resection and vessel reconstruction provide a repository for curative-intent surgery in borderline resectable and locally advanced pancreatic cancer.
