Patients with later stage, nonsquamous NSCLC, particularly those receiving induction chemotherapy, have sufficiently common BM rates to justify future trials including prophylactic cranial irradiation.

Our analysis supports the hypothesis that response to chemoradiation of non-small cell lung carcinoma improves with increasing hemoglobin levels.

Because of the uncertainties regarding the efficacy of postoperative radiation therapy for early prostate cancer, treatment strategies following radical prostatectomy include: (1) observation alone in high‐risk patients, (2) adjuvant radiation therapy (PSA undetectable) in high‐risk patients, or (3) salvage radiation therapy for biochemical and clinical recurrence. Fifty‐two patients treated with postoperative radiation therapy in either an adjuvant setting (13) or for salvage (39) were retrospectively reviewed. The actuarial biochemical disease‐free survival (bNED) rates following radiation therapy were calculated using the life‐table method. Univariate and multi variate analyses were used to define the clinical factors that predict biochemical failure following postoperative radiation therapy. In addition, the bNED survival rate for 36 high‐risk surgery patients who were simply observed following prostatectomy was determined. The 3‐year bNED survival rate for the adjuvant radiation group was 85% compared with 27% for salvage radiation and 43% for the observation group. These results are statistically significant. Factors that predict biochemical failure following postoperative radiation therapy include preoperative PSA level, pre‐radiation therapy PSA level, and seminal vesicle involvement. At our institutions, adjuvant radiation therapy was a superior strategy compared with either observation alone or salvage radiation therapy for high‐risk postoperative prostate cancer patients. Int.
