Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Although up to 30% of men who undergo radical prostatectomy for clinically organ-confined prostate cancer will relapse with disseminated disease, currently it is not possible to predict these patients.', 'Androgen receptor (AR) immunoreactivity in stromal and epithelial compartments of tumor foci was evaluated by video image analysis in 53 radical prostatectomy specimens. Kaplan-Meier and Cox Regression analyses were used to determine whether AR immunostaining was related to rate and risk of relapse, respectively.', 'Ninety-eight percent (52/53) of the tumors contained AR positive malignant epithelial cells. Kaplan-Meier analysis indicated that patients with high AR levels (>64% AR positive nuclear area) in the malignant epithelial cells or low AR levels (<or=45% AR positive nuclear area) in the peritumoral stroma cells, were more likely to relapse earlier following radical prostatectomy. The shortest time to relapse and the highest relapse rate was for patients with both high AR in the malignant epithelial cells and low AR in the peritumoral stromal cells.

To determine the prognostic role of co-morbidity in medically inoperable early-stage non-small cell lung cancer (NSCLC) treated with stereotactic body radiotherapy (SBRT).', "Between 2000 and 2007, 88 consecutive early-stage medically inoperable NSCLC patients were treated by linac-based SBRT. The dose was either 45 Gy or 67.5 Gy in three fractions prescribed to the isocenter. Baseline co-morbidities were retrospectively retrieved by consultation of a formal electronic registry of diagnoses as well as patients' charts. The age-adjusted Charlson Co-morbidity Index (CCI) was scored for each patient and subjected to univariate and multivariate analysis.", 'With a median follow-up of 44 months, the actuarial local control rate at 4 years was 89% while the median overall survival was 22 months. The median age-adjusted CCI score was 5. The age-adjusted CCI was a significant predictor of overall survival on both univariate (p=0.002) and multivariate analysis (p=0.011). Patients with an age-adjusted CCI score of 3 or less had a median survival of 41 months versus only 11 months for those scoring 6 or more.

In chronic renal failure leptin levels are elevated and BMD decreased, however, so far data about correlations between leptin and BMD in dialyzed patients are scarce. It has been suggested that leptin is a predictor of BMD in postmenopausal women. We examined the relationships between leptinemia, BMD and bone metabolism in HD and CAPD patients. We also assessed whether leptin is significant and independent predictor of BMD in dialyzed patients.', 'BMD was measured using dual energy X-ray absorptiometry (DEXA) at lumbar spine and femoral neck in 25 HD and 23 CAPD patients. Markers of bone turnover and leptin were studied using commercially available kits.', 'In femoral neck BMD was significantly higher in CAPD patients, without significant differences in BMD in lumbar spine. There was a negative correlation between BMD at the femoral neck and time on hemodialysis (r= -0.45, p < 0.05). In CAPD patients BMD at the lumbar spine correlated negatively with vitamin D3 (r= -0.54, p < 0.05), osteocalcin (r= 0.54, p < 0 .05), and positively with BMI (r= 0.63, p < 0.01). BMD at the femoral neck correlated positively with BMI (r= 0.59, p < 0.01), and negatively with osteocalcin (r= -0.63, p < 0.05) and time on CAPD (r= -0.52, p < 0.05). Leptin correlate only with cholesterol (r= 0.25, p < 0.05), TSH (r= 0.35, p < 0.01), ss(2) microglobulin (r= 0.32, p < 0.001) and BMD at the femoral neck (r= -0.23, p < 0.05)in all dialyzed (HD and CAPD) patients.
