Survival Among Patients With Pancreatic Cancer Depending on Surgical Resection Rate

March 15, 2021 updated by: Bergthor Björnsson, Linkoeping University

Survival Among Elderly Patients in Sweden With Right-sided Pancreatic Adenocarcinoma Depending on Resection Rate of Pancreaticoduodenectomy

The primary aim of this population-based study is to investigate how a high resection rate of pancreaticoduodenectomy affects overall survival among patients aged ≥70 years with pancreatic ductal adenocarcinoma. The secondary aim is to determine if a high resection rate of pancreaticoduodenectomy increases perioperative morbidity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.
Observational

Enrollment (Actual)

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
Overall survival
Time Frame: A little more than 10 years (from first patient to vital status)
Overall survival among patients aged 70 years and over with pancreatic ductal adenocarcinoma in the pancreatic head
A little more than 10 years (from first patient to vital status)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Severe complications after pancreaticoduodenectomy
Time Frame: Around 10 years (patients diagnosed between 1 January 2010 and 31 December 2018, latest dismissal from hospital january 2020)
The rate of severe complications among patients aged 70 years and over who had undergone pancreaticoduodenectomy for any reason
Around 10 years (patients diagnosed between 1 January 2010 and 31 December 2018, latest dismissal from hospital january 2020)

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2010

Primary Completion (Actual)

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
