This previous version of this study was a phase I dose escalation trial giving 25 Gy in 10 fractions to the whole brain with simultaneous infield boost (SIB) to a total of 45 Gy in 10 fractions to gross brain metastatic disease. Prior to this, patients were enrolled onto one of two cohorts with whole brain dose of 30 Gy in 10 fractions with SIB to total of 45 Gy in 10 fractions to gross brain metastatic disease or whole brain dose of 37.5 Gy in 15 fractions with SIB to total of 52.5 Gy in 15 fractions to gross brain metastatic disease. A total of 12 patients have been previously enrolled on this trial. No patients have experienced a dose limiting toxicity (grade 3 or above) at least possibly due to study therapy. Also, no patients experienced local brain failure/progression at a site of treated metastatic brain disease. Based on this, we no longer feel that dose escalation to the gross brain disease is warranted and would proceed with a single arm pilot study treating patients with 25 Gy in 10 fractions to the whole brain with simultaneous infield boost (SIB) to a total of 45 Gy in 10 fractions to gross brain metastatic disease.
