Does Recurrent Pancreatic Cancer Really Have Similar Outcome Compared With Primary Metastatic Pancreatic Cancer?

April 3, 2025 updated by: Takehiro Okabayashi, Kochi University
The recurrent pancreatic cancer (Rec-PC) after radical surgery is sometimes eligible to clinical trial of chemotherapy for unresectable pancreatic cancer. However, the difference between Rec-PC and primary metastatic pancreatic cancer (PM-PC) did not know well. Thus, whether Rec-PC and PM-PC should be included in the same category when conducting clinical trials evaluating chemotherapy remains controversial. The purpose of this study is to investigate the difference of overall survival (OS) between Rec-PC and PM-PC, and analyze their impact on prognosis.

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)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
276

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.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

A retrospective database review of patients with recurrent or primary metastatic pancreatic cancer at a single institution, from 2010 to 2023, was conducted.

Description

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

chemotherapy for metastatic pancreatic cancer
chemotherapy
Drug: chemotherapy agents
Overall, data of 276 patients (144 men and 132 women, 224 Rec-PC and 51 PM-PC) were retrospectively analyzed. The median patient age was 70 (range; 29-91) years. Serum carbohydrate antigen (CA) 19-9 among Rec-PC group (median; 207 U/mL) and PM-PC group (median; 1680 U/mL) was statistically different. Rec-PC patients received gemcitabine plus nab-paclitaxel (106), S-1 (37), gemcitabine (22), FOLRIFINOX (18) and other (8) regimen as a first line chemotherapy. 67 Rec-PC patients underwent any local treatment. PM-PC patients received gemcitabine plus nab-paclitaxel (34), FOLRIFINOX (8), gemcitabine (5), S-1 (2) and other (2) regimen as a first line chemotherapy.

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
Time Frame
Overall survival
Time Frame: From date of evaluation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months
From date of evaluation until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 24 months

Study Major Dates

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.
