Study Overview
Brief Summary
Single institution study of safety of linac based VMAT TBI for myeloablative treatment in hematologic malignancies.
Detailed Description
Total Body Irradiation (TBI) continues to play an important role in myeloablative and non-myeloablative conditioning regimens for Allogeneic Stem Cell Transplant (ASCT). When TBI is used as part of a myeloablative regimen, it is combined with chemotherapy to eradicate malignant cells, as well as to immunosuppress the host to prevent rejection of donor hematopoietic progenitor cells (HPC).
This study is a single-institution study to assess the safety of linac based VMAT TBI for myeablative sreatment in hematologic malignancies.

Exclusion Criteria
- •l per BMT SOPs.
- •BMT program will initiate referral, utilizing Form: 170102, Radiation Oncology Consultation.

Outcomes
Primary Outcomes
Proportion of patients who achieve excellent coverage while sparing the lung
Time Frame: Up to 1 year post-transplant
Excellent coverage while sparing the lung is quantified by meeting the following dosimetric parameters (all parameters must be met): 1. V100%= \>90% (90% of PTV volume getting 100% of the dose). 2. D98\>85% (98% of the volume getting at least 85% of the dose). 3. Mean Lung dose \<900cGy.
Proportion of Patients Who Achieve Excellent Coverage While Sparing the Lung
Time Frame: Up to 1 year post-transplant
Excellent coverage while sparing the lung is quantified by meeting the following dosimetric parameters (all parameters must be met): 1. V100%= \>90% (90% of PTV volume getting 100% of the dose). 2. D98\>85% (98% of the volume getting at least 85% of the dose). 3. Mean Lung dose \<900cGy.
