Abstract Most adults with acute lymphoblastic leukemia (ALL) who achieve complete remission (CR) will relapse. We examined the outcome of 609 adults with recurring ALL, all of whom were previously treated on the Medical Research Council (MRC) UKALL12/ECOG2993 study, where the overall survival (OS) of newly diagnosed patients is 38% (95% confidence interval [CI] = 36%-41%) at 5 years. By contrast, OS at 5 years after relapse was 7% (95% CI = 4%-9%). Factors predicting a good outcome after salvage therapy were young age (OS of 12% in patients younger than 20 years vs OS of 3% in patients older than 50 years; 2P < .001) and short duration of first remission (CR1) (OS of 11% in those with a CR1 of more than 2 years versus OS of 5% in those with a CR1 of less than 2 years; 2P < .001). Treatment received in CR1 did not influence outcome after relapse. In a very highly selected subgroup of patients who were able to receive HSCT after relapse, some were long-term survivors. We conclude from a large, unselected series with mature follow-up that most adults with recurring ALL, whatever their prior treatment, cannot be rescued using currently available therapies. Prevention of recurrence is the best strategy for long-term survival in this disease.

Human papillomavirus DNA has been detected in the semen of three patients, two of whom have severe chronic wart disease. These data support the contention that sexual transmission of human papillomavirus DNA could occur via semen, a possibility suggested by epidemiological data on the sexual transmission of human papillomavirus.

Because physician turnover, especially during the first 5 years after joining a practice group, has been reported to be as high as 54%, we sought to identify and quantify the factors that lead hand surgeons to leave their practices. An eight-question practice survey was administered to 10 hand surgeons, all of whom had left their practices under various circumstances. All respondents were men (mean age, 43.2 years). Nine surgeons were in their first practice and one was in his second. Time in the practice ranged from 4 months to 6.5 years (mean time, 3.4 years). Questions about surgical practice issues were asked of all survey participants, who were then asked to quantify the influence of the issue on their decision to leave their own surgical practice with a Likert scale ranging from 1 (no influence) to 5 (greatly influenced the decision to leave). The strongest influences on the decision to leave a practice were interpersonal conflict (mean, 4.7 points) and lack of decision-making ability within the practice (mean, 4.2 points). The influence of partnership determination (mean, 3.3 points) was mixed, whereas staff support (mean, 2.9 points), salary agreements (mean, 2.4 points), employment contracts (mean, 1.6 points), and retirement benefits (mean, 1.0 points) played a lesser role in the surgeons' decisions to leave their practices.
