Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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

Retroperitoneal Sarcoma (RPS) which is a rare disease which incidence is 1.79/100,000. The treatment is difficult to due to it anatomy position which often invade to multiple organs and cause the complete surgical resection to be very complex and difficult. It was known to sacrifice one side kidney will improve the resection rate. To this days, successful surgical resection was still the gold standard that provide most benefit in overall survival. To reach that goal, pre-operative radiotherapy was applied to RPS which intended to achieve similar effect in rectal cancer for the down staging effect and improved the respectability but with limited benefit. Herein, investigators conducted this study to find the best way to achieve successful surgical resection and prognostic factor analysis.

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

  • Adult
  • Older Adult

Design Details

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: The proportion of patients still alive at 1 year, 3 years, and 5 years after treatment.
After treatment, patients will undergo long-term follow-up to record their survival status.
The proportion of patients still alive at 1 year, 3 years, and 5 years after 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
Progression free survival
Time Frame: The rates of local recurrence, regional recurrence, or distant metastasis at 1 year, 3 years, and 5 years after treatment.
Progression defined as local, regional, or distant metastasis
The rates of local recurrence, regional recurrence, or distant metastasis at 1 year, 3 years, and 5 years after treatment.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The resectability of preoperative embolization
Time Frame: From the start of preoperative evaluations to the day of surgery, it typically spans 7 days.
Preoperative embolization for assessing resectability combines radiology, angiography, and transcatheter arterial embolization (TAE). Initially, imaging techniques such as X-rays or CT scans are used to understand the characteristics of the lesions. Then, angiography is employed to observe the tumor's blood supply. Finally, TAE not only evaluates the vascular supply to the tumor but also helps reduce its size through embolization, enhancing resectability. The comprehensive results of these assessments contribute to developing a safe and effective surgical plan.
From the start of preoperative evaluations to the day of surgery, it typically spans 7 days.
The value of eGFR in renal function
Time Frame: Period from date before surgery to the date one year after suregry
eGFR is an important biomarker used to assess kidney function and monitor renal health. It represents the volume of blood filtered by the glomeruli per minute, typically expressed in milliliters per minute (mL/min). A venous blood sample will be collected and analyzed in the laboratory to determine the value.
Period from date before surgery to the date one year after suregry

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.
