Spots Global Cancer Trial Database for nTMS in Planning Stereotactic Radiosurgery in Patients With Brain Metastases in the Motor Cortex

Study Description

Brief Summary: This trial studies how well nTMS works in planning for stereotactic radiosurgery in patients with brain metastases in the motor cortex. Stereotactic radiosurgery is a type of radiation therapy that delivers high doses of radiation, which can sometimes lead to damage occurring to the brain and surrounding areas. The motor cortex (the part of the nervous system that controls muscle movement), however, currently has no radiation dose limit. nTMS is a non-invasive tool that uses sensors on a patient's muscle to trace the location in their brain that controls that muscle and is currently used by doctors to decide where to operate so as not to damage the motor nerves. nTMS may effectively help plan radiation treatment using SRS and help doctors decide on how much radiation can be used on motor nerves.

Detailed Description: PRIMARY OBJECTIVES: I. To determine if the use of navigated transcranial magnetic stimulation (nTMS) in the radiation oncology clinic is feasible. SECONDARY OBJECTIVES: I. To investigate the relationship of stereotactic radiosurgery (SRS) dosimetry and lesion involvement in the motor tracts identified using nTMS and the presence or absence of motor deficits evaluated by objective and subjective measures (Manual Ability Measure \[MAM\]-20, Euroqol \[EQ\]-5 Dimensional \[D\]-5 Level \[L\], and MD Anderson Symptom Inventory \[MDASI\]-Brain Tumor \[BT\] questionnaires). II. To determine if nTMS of contralateral motor tracts provides a viable internal control, considering handedness. III. To aid in the design of a prospective, randomized clinical trial that will limit radiation dose to brain metastases located in close proximity to the motor cortex with the goal of improving functional and quality of life outcomes measured by occupational therapy tasks and the MAM-20, EQ-5D-5L, and MDASI-BT questionnaires. IV. To explore the utility of electroencephalography (EEG) in correlation with nTMS and reported functional outcomes measured by occupational therapy tasks and the MAM-20, EQ-5D-5L, and MDASI-BT questionnaires. OUTLINE: Patients undergo nTMS over 1 hour. Patients also perform 4 tasks that test grip and pinch strength and the ability to use and feel with their hands for 1 hour.
