简要总结
The purpose of this study is to see whether designing radiation to spare the vertebral bone marrow can limit the rates of lymphopenia during standard of care chemoradiation therapy and in the time to count recovery in the ensuing weeks. Secondary endpoints will examine whether this leads to improved disease control whether this is predictive of improved clinical outcomes such as rates of local recurrence (LR), metastasis free survival (MFS), overall survival (OS), and progression free survival (PFS) which will be followed prospectively up to 5 years.

结局指标
主要结局
Limited G3L Toxicity
时间窗: 6 weeks
The primary end point will be evaluating whether implementing dosimetric constraints to the bone marrow will decrease rates of G3L toxicity in the peripheral blood compared to expected rates of 40% in large series examining toxicities during chemoradiation. Values will be expressed as a percentage rates of G3L lymphopenia.
次要结局
- Progression free Survival (PFS)(Baseline to study end (up to 5 years))
- Overall Survival (OS)(Baseline to study end (up to 5 years))
- Change in Neutrophil to Lymphocyte ratio (NLR)(Baseline to study end (up to 5 years))
- Local Recurrence (LR)(Baseline to study end (up to 5 years))
- Metastasis Free Survival (MFS)(Baseline to study end (up to 5 years))
