Background: Although most patients with PDAC experience distant failure after resection, a significant portion still present with local recurrence. Intraoperative fluorescent imaging can potentially facilitate the visualization of involved peritumoral LNs and guide the locoregional extent of nodal dissection. Here, the efficacy of targeted intraoperative fluorescent imaging was examined in the detection of metastatic lymph nodes (LNs) during resection of pancreatic ductal adenocarcinoma (PDAC). Read More

The vast majority of patients with pancreatic ductal adenocarcinoma (PDAC) presents with symptomatic, surgically unresectable disease. While the goal of early detection of PDAC is laudable, and likely to result in significant improvement in overall survival, the relatively low prevalence of PDAC renders general population screening infeasible. The challenges of early detection include identification of at-risk individuals in the general population who would benefit from longitudinal surveillance programs, and appropriate biomarker and imaging-based modalities utilized for PDAC surveillance in such cohorts.

Pancreatic ductal adenocarcinoma is one of the leading causes of cancer-related deaths and, currently, surgery is the only curative treatment. Patients with borderline resectable pancreatic cancer (BRPC) can benefit from a multidisciplinary approach and R0 resection, and can achieve the same outcome as resectable patients treated with upfront surgery. However, the definition of BRPC changes according to different classifications with a heterogeneous distribution of patients, and it is thus difficult to compare clinical evidence. Read More

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignancies and has one of the worst prognoses leading to a meager 5-year survival rate of ∼8%. Chemotherapy has had limited success in extending the life span of patients with advanced PDAC due to poor tumor perfusion and hypoxia-induced resistance. Hypoxia reprograms the gene expression profile and upregulates the expression of multiple genes including heme oxygenase-1 (HO-1), which provide survival advantage to PDAC cells. Read More

The laparoscopic technique in distal pancreatic resection (LDP) has been widely accepted, and outcome data support the hypothesis that survival is improved, partly due to improved postoperative safety and recovery, thus optimizing treatment with adjuvant chemotherapy. But laparoscopic pancreaticoduodenectomy (LPD or Whipple-procedures) has spread more slowly, due to the complexity of the procedure. Surgical safety has been a problem in hospitals with low patient volume, resulting in raised postoperative mortality, requiring careful monitoring of outcome during the surgical learning curve.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with limited effective therapeutic options and exceedingly high mortality rates. Currently, cure can only be achieved through resection, however the vast majority of patients present with advanced disease for which upfront surgery is not an option. In an effort to improve surgical candidacy, neoadjuvant chemotherapy, with or without radiation therapy, is often used in an effort to downstage borderline resectable and locally advanced tumors, and some argue for its use even in patients with resectable tumors.
