Introduction

Systematic reviews of the evidence serve as the basis for U.S. Preventive Services Task Force (USPSTF) recommendations on clinical prevention topics. The USPSTF tailors the scope of these reviews to each topic. The USPSTF determined that a brief, focused evidence review was needed to assist in updating its 1996 recommendations on screening for pancreatic cancer.1

Jana Johnson of the RTI-UNC Evidence-based Practice Center (under contract to AHRQ), performed a targeted review of the literature published on this topic between 1994 and 2001

Search Strategy

The MEDLINE® and the Cochrane Library databases were searched for articles dating from 1994 through December, 2001, focusing on systematic reviews, meta-analyses, randomized controlled trials (RCTs), cost-effectiveness analyses, editorials, or commentaries concerning the critical key questions. The National Guideline Clearinghouse™ was also searched for guidelines on this topic.

In the MEDLINE® search, pancreatic cancer and mass screening were exploded, combining these searches with RCT terms. A second search used treatment (including chemotherapy and surgery) in place of screening. Studies of test accuracy (sensitivity and specificity) regarding screening for pancreatic cancer were also searched for.

Key Questions and Results

Key Question 1: Is there new direct evidence that screening provides more benefit than harm?

We examined 44 abstracts but found no RCTs, meta-analyses, or systematic reviews that provided direct evidence about the benefits and harms of screening.

Key Question 2: Are there new tests (or new evidence about old tests) that substantially improve the accuracy of screening?

We examined 73 abstracts but found no study that provided high quality evidence about the accuracy of screening tests to detect pancreatic cancer early.

Key Question 3: Are there new treatments (or new evidence about old treatments) that improve outcomes for people with pancreatic cancer?

We examined 25 abstracts and found 2 papers that describe an ongoing randomized trial in Europe evaluating 3 different adjuvant treatments for pancreatic cancer.2,3 As of that point in 1997, 348 patients had been recruited into the 3 treatment arms and 1 control arm of the study.

Summary

There is little new evidence and no critical ongoing studies of screening for pancreatic cancer. The literature mentions ongoing research on identifying and screening high-risk groups, especially those with tumor markers. Ongoing research regarding treatment involves studies to determine the effectiveness of new adjuvant chemotherapy, radiation, and surgery protocols. Few of these studies are RCTs.
