ABSTRACT: Ductal adenocarcinoma and its variants account for most pancreatic malignancies. High-quality multiphase imaging can help to preoperatively distinguish between patients eligible for resection with curative intent and those with unresectable disease. Systemic therapy is used in the neoadjuvant or adjuvant pancreatic cancer setting, as well as in the management of locally advanced unresectable and metastatic disease. Clinical trials are critical for making progress in treatment of pancreatic cancer. The NCCN Guidelines for Pancreatic Adenocarcinoma focus on diagnosis and treatment with systemic therapy, radiation therapy, and surgical resection.

ABSTRACT: OBJECTIVES: Development of targeted therapies for pancreatic cancer could be enhanced by a reliable method for noninvasive tumor cell assessment. In this pilot study, we isolated and phenotypically characterized circulating tumor cells (CTCs) from patients with metastatic pancreatic cancer and explored their relationship to clinical outcome. METHODS: Peripheral blood from 50 patients was collected at treatment initiation and first disease evaluation for CTC enumeration and phenotyping by CellSearch® system. Expression of human mucin 1 (MUC-1) was performed. RESULTS: Forty-eight and 37 patients had evaluable samples at baseline and first disease evaluation, respectively. The cohort was 62% male, with a median age of 63 years. At least 1 CTC per 7.5 mL was detected in 23 patients (48%) pretreatment and 11 patients (30%) at first disease evaluation. No difference was seen in overall survival between patients with 1 or more CTCs versus no CTC at baseline (P = 0.14). Patients with MUC-1 expressing CTC (n = 10) had shorter median overall survival compared with those with MUC-1 negative CTC (n = 13; 2.7 vs 9.6 m; P = 0.044). CONCLUSIONS: Circulating tumor cell enumeration and phenotypic characterization from metastatic pancreatic cancer patients are feasible. No correlation was found between CTC isolation and survival. However, the presence of MUC-1 expressing CTC demonstrated a trend toward inferior survival.

3 Article Patterns of care and outcomes of older versus younger patients with metastatic pancreatic cancer: A Fox Chase Cancer Center experience. 2015

ABSTRACT: BACKGROUND: Older patients with metastatic pancreatic cancer (mPC) are poorly represented in clinical trials. We compared patterns of care and outcomes of patients with mPC < and >65 yrs (Group 1 and Group 2, respectively) treated at Fox Chase Cancer Center (FCCC) to identify predictors of survival and better understand the treatment approaches. METHODS: Charts of 579 patients with mPC treated at FCCC from 2000 to 2010 were reviewed. Group 1 and Group 2 were compared with respect to baseline, treatment characteristics, and overall survival (OS) after diagnosis of metastatic disease. RESULTS: 299 patients in Group 1 (median age 57) and 280 patients in Group 2 (median age 73) were evaluated. Patients in Group 2 were less likely to receive any chemotherapy for mPC compared to Group 1 (65% vs 75%, p=0.001) and if treated were less likely to receive more than one agent (37% vs 53%, p<0.001). Survival was comparable between the two groups (p=0.16) and Charlson Co-morbidity Index did not emerge as a prognostic factor. Longer OS was associated with higher number of agents used in both groups (p<0.001). Liver metastases conferred worse survival (p=0.02) while lung metastases conferred better survival in both groups (p=0.002). CONCLUSIONS: Older mPC patients are less likely to receive chemotherapy and receive fewer agents yet have similar OS compared to younger patients. OS improves with increasing number of agents, supporting the use of combination chemotherapy in healthy older patients. Our findings encourage enrollment of older patients with mPC with good performance status onto clinical trials with stratification by site of metastases.
