This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.
This phase III trial compares how well endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) versus EBUS-TBNA plus transbronchial mediastinal cryobiopsy works to obtain adequate tissue samples for next generation sequencing (NGS). During usual care, if there is suspicion of cancer, a procedures known as an EBUS-TBNA is done to take sample of lymph nodes to evaluate for cancer spread. If there is suspected cancer in the lymph nodes, multiple samples are taken for molecular testing (NGS) to help guide treatment decisions. It requires a certain amount of tissue to send for the molecular testing which can be achieved with EBUS-TBNA about 70% of the time. Researchers want to find out if adding a biopsy tool currently used in usual care, known as a cryoprobe, can acquire more tissue for molecular analysis. The cryoprobe uses a freezing technique to biopsy and can potentially gather larger and higher quality tissue samples than the standard EBUS-TBNA method.
