May 31, 2016 updated by: Technische Universität Dresden

Randomized Controlled Trial of Robotic vs. Laparoscopic Distal Pancreatectomy for Pancreatic Cancer - The DAVID-study

The present randomized controlled trial evaluates the incidence of R1 resections in patients undergoing robotic distal pancreatectomy compared to the laparoscopic technique.

Detailed Description

Surgical resection the only potentially curative therapeutic approach in patients with pancreatic cancer. Among the clinicopathologic factors that are associated with long-term survival, a complete (i.e. R0) tumor resection is of utmost significance. Numerous reports have already demonstrated detection of tumor cells at the resection margin on microscopic examination (i.e. R1 resection) is associated with poor long-term survival. However, studies using a standardized pathological work-up of operative specimen from patients with pancreatic cancer revealed that most pancreatic resections are R1 resections. Innovative surgical techniques that reduce the incidence of R1 resections may provide a promising approach to improve the outcome of patients with pancreatic cancer.

For patients requiring a distal pancreatectomy, a laparoscopic pancreatic resection is increasingly performed, as it may enhance postoperative recovery without compromising oncological safety compared to the open approach. However, laparoscopic technique does not affect the proportion of patients with complete (R0) resections. Furthermore, the inability to control major vasculature frequently results in conversion to the open approach. The vast majority of R1 margins are located at the retroperitoneal dissection surface. Due to technical limitations, the open and the laparoscopic technique may not further reduce the incidence of positive resection margins at this location.

The 3D visualization provided by the robotic approach together with improved dexterity of the surgeon are likely to enable a meticulous dissection at the posterior dissection margin. This may result in a significant reduction of patients with positive resection margins. However, to date there has been no randomized controlled trial that compared the robotic to the laparoscopic technique. As health-care interventions need to prove efficacy and safety in well-designed randomized controlled trials, the present randomized controlled trial was designed to test, if robotic distal pancreatectomy increases the incidence of patients with complete (R0) tumor resection for pancreatic cancer. Secondary endpoints include oncological parameters such as the number of harvested lymph nodes and factors of perioperative outcome such as perioperative complications (Clavien-Dindo classification), pancreatic fistula, in-hospital mortality, blood loss and conversion rates.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
R1 resection rate
Time Frame: 10 days
Proportion of patients with complete macroscopic resection, but microscopic residual tumour. Pathological evaluation will be performed by experienced, board-certified pathologists using standardized protocols according to current guidelines. Importantly, pathologists will be blinded for patients treatment group.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Primary Completion (ANTICIPATED)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
