NCT00002838
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy and kill more cancer cells. PURPOSE: Phase I/II trial to study the effectiveness of combination chemotherapy plus peripheral stem cell transplantation in treating patients with refractory chronic lymphocytic leukemia.
NCT00901420
Objectives: The primary objective of this study is to determine whether bladder compliance is significantly lower in men who undergo prostatectomy for recurrence following primary radiation therapy than in men who undergo prostatectomy as primary treatment. The secondary objective is to examine the quality-of-life items addressed in the UCLA Prostate Cancer Index for differences between the two populations. The investigators will also look at secondary objective urodynamic measures, such as bladder capacity, to assess for a difference.
NCT00477256
Primary Objectives: 1. To examine illness-related factors (i.e., severity of illness, quality of life rating) as predictors or correlates of child adjustment to pediatric cancer. 2. To examine illness-related factors (i.e., severity of illness, quality of life rating) as predictors of school reintegration (i.e., school attendance) in children with pediatric cancer. 3. To examine a within-parent factor (i.e., parental stress) as a predictor or correlate of child adjustment to pediatric cancer. 4. To examine a within-parent factor (i.e., parental stress) as a predictor or correlate of school reintegration (i.e., school attendance). Secondary Objectives: 1. To examine a second within-parent factor (i.e., parental perception of child vulnerability) as a predictor or correlate of child adjustment to pediatric cancer. 2. To examine a second within-parent factor (i.e., parental perception of child vulnerability) as a predictor or correlate of school reintegration (i.e., school attendance) in children with pediatric cancer. 3. To develop a statistical model by which relative contributions of each predictor variable (i.e., severity of illness, quality of life, parental stress, parental perception of child vulnerability), as well as their interrelatedness, can be understood in relation to child adjustment. Exploration of each variable's contribution will affect the schematic organization of the model. 4. To examine demographic variables as covariates in the primary analyses. The variables include: child's age, gender, grade, ethnicity, diagnosis, time since diagnosis, type and duration of treatment, and time since school reintegration.
