Liquid Biopsies in Pediatric Solid Tumors

August 19, 2024 updated by: Fariba Navid, Children's Hospital Los Angeles

Liquid Biopsies in Non-CNS Malignant Pediatric Solid Tumors

This study is being done to determine if traces of tumor can be found in the blood before, during, and after patients stop treatment. We will analyze the tumor material to see if it is similar to tumor tissue and if the tumor material in blood is helpful in monitoring the disease.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
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

Liquid biopsies, particularly those involving cell-free DNA (cfDNA), are a promising non-invasive, cost effective method of monitoring disease in cancer patients with solid tumors and are being increasingly employed in various adult malignancies to diagnose disease, monitor tumor response, detect relapse and learn more about tumor biology. The utility of liquid biopsies which may include isolation and analysis of tumor derived material such as DNA, RNA, intact cells, proteins, or exosomes from blood or other bodily fluids in pediatric solid tumors has not been established. In this study, we propose to prospectively collect serial blood samples at baseline, during therapy, end of therapy, relapse, and during follow up from patients ≥ 6 months of age with newly diagnosed or relapsed/refractory various pediatric non-CNS malignant solid tumors to determine the feasibility of detecting various tumor-derived material, including exosomes, circulating tumor cells, and circulating tumor nucleic acid (ctDNA and ctRNA). The timing of blood sample collection will be during a routine lab draw around the time of a disease evaluation. The ctDNA and ctRNA as well as DNA and RNA extracted from tumor-derived exosomes will be quantified at each time point and the findings will be correlated with conventional methods for disease evaluation (e.g., imaging studies, histologic tumor response, or serum tumor markers) and outcome (overall survival and event-free survival).

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

6 months and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Patients over the age of 6 months who are newly diagnosed, relapsed, or refractory histologically confirmed high grade bone or soft tissue sarcoma or malignant renal, thyroid, germ cell, or hepatic tumors. Also, healthy individuals with no history of cancer or chronic medical problems who are < 21 years of age.

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
To detect circulating tumor DNA (ctDNA) in serial blood samples from patients with pediatric non-CNS solid tumors using low pass whole genome sequencing.
Time Frame: 10 years
To determine how often circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), and circulating tumor RNA (ctRNA) is detected in serial blood samples from patients with newly diagnosed and relapsed/refractory malignant pediatric solid tumors.
