Predicting the risk of pelvic node involvement among men with prostate cancer in the contemporary era.
The "Roach formula" for the risk of pelvic lymph node metastases [(2/3) ( *) PSA + (Gleason score - 6) ( *) 10] was developed in the early prostate-specific antigen (PSA) era. We examined the accuracy of this formula in contemporary patients. ⋯ Applied to contemporary patients with mainly T1c/T2 disease, the Roach formula appears to overestimate pelvic lymph node risk. The adjustment factors presented here should be validated by using biopsy Gleason scores and extended lymphadenectomies.

Estimation of citation-based scholarly activity among radiation oncology faculty at domestic residency-training institutions: 1996-2007.
Advancement in academic radiation oncology is largely contingent on research productivity and the perceived external influence of an individual's scholarly work. The purpose of this study was to use the Hirsch index (h-index) to estimate the research productivity of current radiation oncology faculty at U.S. academic institutions between 1996 and 2007. ⋯ Using the h-index as a partial surrogate for research productivity, it appears that radiation oncologists in academia today comprise a prolific group, however, with a highly skewed distribution. According to the present analysis, the h-index correlated with academic ranking. Thus, it potentially has utility in the process of promotion decisions. Overall, women in radiation oncology were less academically productive than men; the possible reasons for the gender differential are discussed.
