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.

Detailed Description

The question of how to administer adequate chemotherapy to synchronize SBRT treatment strategy to maximize the benefits of neoadjuvant therapy for improved prognosis of patients with borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer is a challenging and debatable issue. No studies have yet evaluated the efficacy of split-course SBRT as the neoadjuvant chemoradiotherapy regimen. The investigators aimed to study whether neoadjuvant chemotherapy plus split-course SBRT results in better outcomes in BRPC and LAPC patients.

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

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
Kaplan-Meier Estimate of Progression-Free Survival (PFS)
Time Frame: From enrollment to 2 years after the end of treatment
Progression-free Survival (PFS) was defined as the time from the date of the first dose to the date of disease progression or death (by any cause), whichever is earlier. The analysis day was calculated from enrollment date for one participant who was not treated. Participants who have no disease progression or have not died were censored to last tumor assessment date with progression-free.
From enrollment to 2 years after the end of treatment

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
Kaplan-Meier Estimates for Time to Treatment Failure (TTF)
Time Frame: From enrollment to 2 years after the end of treatment
TTF was defined as the time after the first dose of study therapy to discontinuation of study therapy due to disease progression, death by any cause, or the start of a new non-protocol-defined anticancer therapy/surgery.
From enrollment to 2 years after the end of treatment
Disease Control Rate (DCR)
Time Frame: From enrollment to 2 years after the end of treatment
DCR was defined as the percentage of participants with a CR or PR or SD from of date of first treatment to 16 weeks. Tumor assessments after start of non-protocol-defined anticancer therapy were excluded.
From enrollment to 2 years after the end of treatment
Overall Response Rate (ORR)
Time Frame: From enrollment to 2 years after the end of treatment
ORR was defined as the percentage of participants that achieved a combined incidence of complete (CR) and partial response (PR) using RECIST 1.1 guidelines as assessed by the investigator.
From enrollment to 2 years after the end of treatment
Kaplan-Meier Estimates for Overall Survival (OS)
Time Frame: From enrollment to 2 years after the end of treatment
Overall survival was defined as the time from the date of first dose of study therapy to the date of death (by any cause).
From enrollment to 2 years after the end of treatment
Participants With Treatment Emergent Adverse Events (TEAEs)
Time Frame: From enrollment to 2 years after the end of treatment
TEAEs are defined as any adverse event (AE) that begin or worsen on or after the start of study drug or procedure of the study period through the maximum duration of the period plus 28 days.
From enrollment to 2 years after the end of treatment
