Official title

Spatially Fractionated Radiation (Grid) Therapy for Tumors of the Head & Neck, Thorax, Abdomen, Pelvis, and Extremities

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This study is an observational registry study evaluating the clinical outcomes of grid therapy. Subjects will be screened at outpatient clinic visit appointments and interested qualified subjects will be consented and offered participation in this study. Once consent has been obtained, baseline adverse event and QOL data will be collected and subjects will undergo grid therapy and follow-up at 2-4 weeks (for toxicity), and 3-6 months (for toxicities and radiographic control) then per clinical discretion up to 1 year. Patients will be evaluated according to the physician's standard practice and discretion. Patient data will be drawn from the patients' medical records and reported by means of a web-based electronic data collection (EDC) system. Patients will be considered "on study" until 60 months of observation has occurred, withdrawal of consent, lost to follow-up, or study closure. See below for the clinical visit flowchart for data collected at baseline and standard clinic visits.
