Trial summary

The limited evidence on the value of portal vein resection in patients with borderline resectable and/or locally advanced PanNENs is an incentive to carry out a retrospective multicentre study amongst centres with specific interest in the management of PanNENs and with experience on vascular reconstruction.

About this study

Official title: Vascular Resection During Pancreaticoduodenectomy for Pancreatic Neuroendocrine Neoplasms (PanNENs): a Comparative Single Centre Study

The limited evidence on the value of portal vein resection in patients with borderline resectable and/or locally advanced PanNENs is an incentive to carry out a retrospective multicentre study amongst centres with specific interest in the management of PanNENs and with experience on vascular reconstruction. Unlike previous studies on pancreatic cancer, it is more difficult to standardise the comparative parameters as the definition of borderline resectable disease has never been published for PanNENs. Similarly, different histological classifications make impossible to collect data exclusively on T3 tumours. Therefore, we aim to compare the short and long-term outcomes (including the impact of the histological depth of vascular invasion on survival) between patients undergoing standard PD and PD with portal vein resection for PanNENs, (regardless of T stage), by collecting and analysing retrospective data in this single centre study

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Portal vein resection / reconstructionProcedure or surgery

    Portal vein resection and reconstruction, with or without concommitant arterial resection

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Progression-Free Survival

    Time from surgery to disease progression, or death or completion of follow up

    Measured: total of 2 years retrospective follow up

Secondary outcomes (2)
  1. Morbidity and mortality rate

    Postoperative morbidity and mortality

    Measured: total of 2 years retrospective follow up

  2. Histology predictive value

    Predictive value of histologically proven invasion of the portal vein adventitia

    Measured: total of 2 years retrospective follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Pancreas Neoplasm and Neuroendocrine Tumors, run by Royal Free Hospital NHS Foundation Trust.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 7 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Panagis M Lykoudis, MD, MSc (+44(0)7413738787, p.lykoudis@ucl.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-Free Survival (time frame: total of 2 years retrospective follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04336839, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2020.
