Age as an independent prognostic factor in patients with glioblastoma: a Radiation Therapy Oncology Group and American College of Surgeons National Cancer Data Base comparison.

Glioblastoma (GBM) is rare in early adulthood and little information is available on this subgroup. We investigated whether young age (18-30 years) had an independent effect on survival. We retrospectively reviewed patients from two large databases: Radiation Therapy Oncology Group (RTOG) and American College of Surgeons National Cancer Data Base (NCDB).

Adjuvant high dose rate brachytherapy (Ir-192) in the management of keloids which have recurred after surgical excision and external radiation.

We describe our experience with adjuvant high dose rate brachytherapy (Ir-192) (HDRB) in patients, who failed surgery and post-operative external radiation therapy. The salvage treatment consisted of excision of the keloid and wound closure followed by HDRB (15 Gy in three fractions given on three consecutive business days beginning the day of surgery). At the time of last follow up, 88% (15/17) of the keloids were without any evidence of recurrence.
