Patient satisfaction with treatment decisions for clinically localized prostate carcinoma. Results from the Prostate Cancer Outcomes Study.

BACKGROUND: Men with early-stage prostate carcinoma can choose aggressive treatment or conservative management. The authors used data from a population-based cohort of men with clinically localized prostate carcinoma to describe satisfaction with treatment decisions 24 months after diagnosis and to examine the association of demographic, socioeconomic, and clinical characteristics with treatment satisfaction. METHODS: The authors evaluated 2365 men with clinically localized prostate carcinoma, diagnosed between October 1994 and October 1995, in one of six Surveillance, Epidemiology, and End Results tumor registries and who were available for 24 month follow-up. Medical record review and patient-completed surveys provided demographic, socioeconomic, and clinical data and measured treatment satisfaction. Logistic regression analyses were used to identify factors associated with satisfaction. RESULTS: Overall, 59.2% of subjects were delighted or very pleased with their treatment selection. The perception of being cancer free (66.4%), maintaining urinary (64.2%) and bowel (60.5%) control and normal erectile function (65.9%), having good general health (71.3%), and preserving social relationships (68.1%) were significantly associated with being satisfied (P < 0.05). Men receiving no active treatment were less satisfied (50.5%, P < 0.001) than actively treated men, and Hispanic men were less satisfied than non-Hispanic white men after undergoing radical prostatectomy (50.1% vs. 58.0%, P = 0.05) or androgen deprivation (29.7% vs. 71.8%, P < 0.02). CONCLUSIONS: The majority of men were satisfied with their treatment selection for clinically localized prostate carcinoma. Receiving an active treatment, believing oneself to be free of cancer, avoiding treatment complications, and having good overall health and social support were positively associated with satisfaction.

Laser prostatectomy versus transurethral resection for treating benign prostatic obstruction: a systematic review.

PURPOSE: We conducted a systematic review of randomized controlled trials evaluating the efficacy and safety of laser prostatectomy techniques compared to transurethral resection of the prostate for symptomatic benign prostatic obstruction. MATERIALS AND METHODS: We searched MEDLINE, the Cochrane library and reference lists of retrieved studies to identify randomized trials of 6 months or greater in duration with at least 10 subjects in each treatment arm. We extracted data on study design, subject and treatment characteristics, adverse events, urinary symptoms and urinary flow. RESULTS: A total of 16 studies involving 1,488 subjects were evaluated, including 8 comparisons of transurethral resection with contact lasers, 7 with noncontact lasers and 4 with hybrid techniques. Study duration ranged from 6 to 36 months. Mean patient age (67.4 years), baseline symptom score (20.2) and peak urinary flow (9.5 ml. per second) did not differ by treatment group. Transurethral resection of the prostate provided slightly greater improvement in urinary symptoms and flow. The pooled mean percentage improvement for urinary symptoms ranged from 59% to 68% with lasers and 63% to 77% with transurethral resection. Improvement for peak urinary flow ranged from 56% to 119% with lasers and 96% to 127% with transurethral resection of the prostate. Laser procedures resulted in fewer transfusions (less than 1% versus 7%) and strictures (0% to 7% versus 8%), and required shorter hospitalizations. Reoperation occurred more often (RR = 5.7) following laser procedures. CONCLUSIONS: Laser techniques are a useful alternative to transurethral resection of the prostate for treating benign prostatic obstruction. Small sample sizes and differences in study design limit any definitive conclusions regarding the preferred type of laser technique.

Effects of misattribution in assigning cause of death on prostate cancer mortality rates.

PURPOSE: Estimate the magnitude of misattribution in death certification and to determine whether misattribution could explain temporal trends in New Mexico prostate cancer mortality. METHODS: Investigators retrospectively reviewed medical records to classify cause of death for men with prostate cancer who died in New Mexico in either 1985 or 1995. The investigator-assigned cause of death, either prostate cancer or another cause, was compared with the New Mexico Bureau of Vital Statistics' (BVS) assignment. Net misattribution was the difference between BVS and investigators in the number of deaths attributed to prostate cancer relative to the number attributed by investigators. RESULTS: Concordance for death certification between BVS and investigators was higher in 1995 (95.8%) than 1985 (85.1%), p <0.01, but net misattribution was higher in 1995 (16.8% vs. 1.9%). During this time, the crude prostate cancer mortality rate in New Mexico increased 33.5%, from 18.5 to 24.7 per 100,000. However, after adjusting for misattribution, mortality increased only 15.9%, from 18.2 to 21.1 per 100,000. CONCLUSIONS: Net misattribution in death certification was higher in 1995 than 1985. The adjusted increase in crude mortality rates was substantially less than the observed increase, suggesting that misattribution explained about half of the observed increase.

Intensified blood glucose monitoring improves glycemic control in stable, insulin-treated veterans with type 2 diabetes: the Diabetes Outcomes in Veterans Study (DOVES).

OBJECTIVE: To examine the effect of intensified self-monitored blood glucose (SMBG) testing on glycemic control. RESEARCH DESIGN AND METHODS: Subjects with stable, insulin-treated type 2 diabetes performed SMBG using an electronic blood glucose meter before all meals and at bedtime for 8 weeks. Baseline data were collected on demographics, clinical characteristics, diet, and exercise. HbA(1c) was measured at baseline, at 4 weeks, and at 8 weeks. After the intensified monitoring period, subjects resumed their usual monitoring. HbA(1c) was then measured at 24, 37, and 52 weeks. Multivariate linear regression was used to determine the effect of monitoring on glycemic control. RESULTS: A total of 201 subjects completed the monitoring period. The baseline HbA(1c) (8.10 +/- 1.67%) decreased during the monitoring period by 0.30 +/- 0.68% (P < 0.001) at 4 weeks and by 0.36 +/- 0.88% (P < 0.001) at 8 weeks. Although entry HbA(1c) and compliance independently predicted the week 8 HbA(1c) (r = 0.862, P < 0.001), standardized regression analysis found that compliance with the SMBG protocol influenced the week 8 HbA(1c) more than age, sex, BMI, exercise level, carbohydrate consumption, or treatment intensity at baseline. However, SMBG benefited only subjects whose testing compliance exceeded 75% or with an entry HbA(1c) >8.0%. Decreases in HbA(1c) (-0.31 +/- 1.17%, P = 0.001) persisted in the 159 subjects followed for 52 weeks. CONCLUSIONS: Intensified blood glucose monitoring improved glycemic control in a large cohort of stable, insulin-treated veterans with type 2 diabetes. SMBG provided a strong stimulus for improved self-care resulting in clinically important and sustained reductions in HbA(1c).

Family history, Hispanic ethnicity, and prostate cancer risk.

Family history is known to be a prostate cancer (CaP) risk factor for non-Hispanic Whites (NHWs) and African Americans, but little data are available on the risk for Hispanics (Hs). This population-based case-control study used mailed surveys to assess the effects of ethnicity and family history of CaP on CaP risk in Hs and NHWs. Cases (N = 351) were those identified by the New Mexico Tumor Registry as having been newly diagnosed with CaP from October 1, 1994 to October 31, 1995. Controls (N = 618) were randomly selected and frequency-matched to cases by ethnicity and 5-year age groups. Multivariate analyses were conducted using conditional logistic regression. After controlling for age, education, and income in the models, positive family history increased risk for both Hispanics (H) (OR 2.7, 95% CI 1.5-4.7) and non-Hispanic Whites (NHW) (OR 2.0, 95% CI 1.3-3.1), suggesting that having a family history of CaP is a risk factor for both ethnic groups.

Prostate-specific antigen testing accuracy in community practice.

BACKGROUND: Most data on prostate-specific antigen (PSA) testing come from urologic cohorts comprised of volunteers for screening programs. We evaluated the diagnostic accuracy of PSA testing for detecting prostate cancer in community practice. METHODS: PSA testing results were compared with a reference standard of prostate biopsy. Subjects were 2,620 men 40 years and older undergoing (PSA) testing and biopsy from 1/1/95 through 12/31/98 in the Albuquerque, New Mexico metropolitan area. Diagnostic measures included the area under the receiver-operating characteristic curve, sensitivity, specificity, and likelihood ratios. RESULTS: Cancer was detected in 930 subjects (35%). The area under the ROC curve was 0.67 and the PSA cutpoint of 4 ng/ml had a sensitivity of 86% and a specificity of 33%. The likelihood ratio for a positive test (LR+) was 1.28 and 0.42 for a negative test (LR-). PSA testing was most sensitive (90%) but least specific (27%) in older men. Age-specific reference ranges improved specificity in older men (49%) but decreased sensitivity (70%), with an LR+ of 1.38. Lowering the PSA cutpoint to 2 ng/ml resulted in a sensitivity of 95%, a specificity of 20%, and an LR+ of 1.19. CONCLUSIONS: PSA testing had fair discriminating power for detecting prostate cancer in community practice. The PSA cutpoint of 4 ng/ml was sensitive but relatively non-specific and associated likelihood ratios only moderately revised probabilities for cancer. Using age-specific reference ranges and a PSA cutpoint below 4 ng/ml improved test specificity and sensitivity, respectively, but did not improve the overall accuracy of PSA testing.

Using multiple cutpoints for the free-to-total prostate specific antigen ratio improves the accuracy of prostate cancer detection.

BACKGROUND: Using a single cutpoint for the free-to-total (F/T) prostate specific antigen (PSA) ratio loses important diagnostic information. We evaluated the performance of multiple F/T PSA cutpoints in detecting prostate cancer in men with nonspecific PSA values. METHODS: We extracted sensitivity and specificity data from 12 studies reporting on >or=30 cancer patients with PSA values between 2.0 and 10.0 ng/mL. We calculated stratum-specific likelihood ratios (LR) and areas under the receiver operating characteristic (ROC) curves. RESULTS: Multiple cutpoints for the F/T PSA ratio significantly increased the area under the ROC (0.70) compared with the single investigator-selected cutpoint (0.62), P < 0.004. The LR for the most positive cutpoint stratum (2.62) was significantly higher than the LR for a positive test from the single cutpoint (1.36), P < 0.004. CONCLUSIONS: Using multiple cutpoints increased the discriminating power of the F/T PSA ratio and led to greater probability revisions in the most positive test-result strata.

Quality of life following localized prostate cancer treated initially with androgen deprivation therapy or no therapy.

BACKGROUND: Many men diagnosed with clinically localized prostate cancer are initially treated conservatively, receiving neither surgery nor radiotherapy for the first year. Treatment patterns and quality-of-life outcomes have not been previously reported for a population-based sample of such men. METHODS: A population-based random sample of men (n = 661) from six geographic regions who had been newly diagnosed with clinically localized prostate cancer from 1994 through 1995 were followed for up to 1 year. Eligible subjects received neither surgery nor radiotherapy within 1 year of initial diagnosis. We assessed disease-specific and generic quality-of-life outcomes in men receiving androgen deprivation therapy (ADT) compared with men receiving no therapy. All statistical tests were two-sided. RESULTS: Two hundred and forty-five study patients received ADT and the remaining 416 patients received no therapy. Approximately two thirds of the patients (n = 159) receiving ADT had either baseline Gleason scores greater than six or serum prostate-specific antigen values above 20 ng/mL. Among men who were sexually potent before diagnosis (ADT = 88 patients; no therapy = 223 patients), 80% of those on ADT reported being impotent after 1 year compared with 30% of those receiving no treatment (P < .001). Patients receiving ADT reported more physical discomfort 1 year after diagnosis than did men who had received no therapy. However, patients receiving ADT, compared with those receiving no therapy, were more likely to be satisfied with their treatment decision (56% pleased versus 45.3%; P =.001). Patients on ADT also experienced a statistically significant decline in vitality, but not in physical function, after adjustment for the confounding factors (P =.05). CONCLUSION: ADT is a commonly used primary therapy for clinically localized prostate cancer. Therefore, men considering ADT as an initial treatment should be aware that sexual function and some aspects of physical well-being are likely to be affected in the first year following this treatment.

Weight deficit in patients on continuous ambulatory peritoneal dialysis.

Small solute clearances were compared between two groups of patients on continuous ambulatory peritoneal dialysis (CAPD), an underweight group with a ratio of actual-to-ideal weight (W/IW) less than 0.9 and a normal-weight group with W/IW between 0.9 and 1.2 at the first clearance study after initiation of CAPD. Adequate clearance levels were set according to the K/DOQI guidelines. Duration of follow-up during CAPD and time on CAPD until the first clearance study was similar in the two groups. Initial weekly Kt/V urea and creatinine clearance also were similar. Kt/V urea values were adequate in 41.8% of the underweight subjects and 41.0% of the normal-weight subjects (not significant). Corresponding percentages for creatinine clearance were 36.4% and 39.7% (not significant). Serum creatinine and albumin concentration, creatinine excretion, and lean body mass estimated from creatinine kinetics were lower in the underweight group. Weight measurements from initiation of CAPD were available in 37 underweight patients. At initiation of CAPD, 31 subjects had W/IW less than 0.9, and 6 subjects had W/IW greater than 0.9. Chronic catabolic illness was present at CAPD initiation in 19 patients. Among the 37 patients, 17 lost weight and 6 gained weight during the course of CAPD. Compared with patients who lost weight, those who gained weight were younger (35.6 +/- 9.3 years old versus 58.4 +/- 15.0 years old; P = 0.0069) and had a higher percent of women (80.0% versus 11.8%; P = 0.0093), higher initial weekly Kt/V urea (2.58 +/- 0.50 versus 1.91 +/- 0.24; P = 0.0087), and a higher percent of adequate Kt/V urea (80.0% versus 11.8%; P = 0.0093). Small solute clearances do not differ between underweight CAPD patients and normal-weight CAPD patients. Underweight CAPD patients usually start CAPD with a weight deficit and have associated catabolic illnesses. Catabolic illness is the sole cause of weight deficit in 40% of the underweight CAPD patients and is present in the remaining 60%. The role of inadequate clearances in the development of weight deficit in CAPD populations is difficult to assess. It seems, however, that adequate Kt/V urea may be necessary for weight gain in underweight CAPD patients.

Evaluating once- and twice-daily self-monitored blood glucose testing strategies for stable insulin-treated patients with type 2 diabetes : the diabetes outcomes in veterans study.

OBJECTIVE: To evaluate once- and twice-daily self-monitored blood glucose testing strategies in assessing glycemic control and detecting hypoglycemia or hyperglycemia in patients with stable insulin-treated type 2 diabetes. RESEARCH DESIGN AND METHODS: Subjects with stable insulin-treated type 2 diabetes monitored blood glucose four times daily (prebreakfast, prelunch, predinner, and bedtime) for 8 weeks. We correlated mean blood glucose values with HbA(1c) measured after 8 weeks and determined the number of hypoglycemic (< or =3.33 mmol/l) and hyperglycemic (> or =22.20 mmol/l) readings captured at the various testing times. RESULTS: A total of 150 subjects completed the monitoring period; their average age was 67 years, 90% were men, and the mean HbA(1c) at baseline was 8.0 +/- 1.8%. The overall correlation of glucose testing and HbA(1c) was 0.79 (P < 0.0001). Mean blood glucose values for each of the four once-daily testing strategies were significantly correlated with HbA(1c) (r = 0.65-0.70, P < 0.0001), as were mean blood glucose values for each of the six twice-daily testing strategies (r = 0.73-0.75, P < 0.0001). The prebreakfast/prelunch measurements captured the largest proportion (63.6%) of the hypoglycemic readings, the predinner/bedtime measurements captured the largest proportion (66.2%) of hyperglycemic readings, and the prelunch/predinner measurements captured the largest proportion (57.7%) of all out-of-range readings. CONCLUSIONS: Twice-daily testing strategies, particularly prelunch/predinner, effectively assess glycemic control and capture a substantial proportion of out-of-range readings. However, personal testing strategies will vary depending on an individual's risk for hypoglycemia and hyperglycemia.

Small solute clearances and nutrition indices in obese patients on continuous peritoneal dialysis.

To investigate the relationship between obesity, small-solute clearances, and nutrition in continuous peritoneal dialysis (CPD), we compared clearances and nutrition indices between 270 obese and 502 normal-weight CPD patients. Degree of obesity was classified by the ratio of body weight (W) to desired weight (DW) at the first clearance study. The DWs were obtained from the tables of the Metropolitan Life Insurance Company, assuming a medium skeletal frame. The obese patients (group I) had W/DW > 1.2 (1.38 +/- 0.17), and the normal-weight patients (group II) had 0.9 < or = W/DW < or = 1.2 (1.05 +/- 0.08). Nutrition indices derived from urea nitrogen and creatinine excretion were normalized by both W and DW. The following variables differed between group I (first value) and group II: sex (women: 48.2% vs. 33.9%), W (87.6 +/- 14.4 kg vs. 68.2 +/- 8.7 kg), body surface area (1.95 +/- 0.22 m2 vs. 1.77 +/- 0.16 m2), body water by method of Watson (41.2 +/- 7.7 L vs. 36.3 +/- 5.5 L), body mass index (31.8 +/- 3.9 vs 24.3 +/- 2.0), protein nitrogen appearance (PNA: 62.9 +/- 17.6 kg in 24 h vs. 57.7 +/- 15.7 kg in 24 h), PNA normalized to DW (1.08 +/- 0.29 g/kg in 24 h vs. 0.96 +/- 0.26 g/kg in 24 h), creatinine excretion (CrEx: 1111 +/- 396 mg in 24 h vs. 991 +/- 348 mg in 24 h), CrEx/W (12.6 +/- 3.7 g/kg in 24 h vs. 15.4 +/- 4.5 g/kg in 24 h), CrEx/DW (17.3 +/- 5.3 g/kg in 24 h vs. 15.1 +/- 4.8 g/kg in 24 h), lean body mass (LBM: 49.3 +/- 13.8 kg vs. 43.6 +/- 11.9 kg), LBM/W (0.56 +/- 0.12 vs. 0.64 +/- 0.15), and LBM/DW (0.77 +/- 0.18 vs 0.67 +/- 0.16), all at p < or = 0.034. Marginal differences (0.10 > p > 0.05) were found in the diabetes prevalence (53.0% vs. 40.8%), height (165.9 +/- 11.7 cm vs. 167.4 +/- 9.8 cm), and serum albumin (3.64 +/- 0.55 g/dL vs. 3.53 +/- 0.62 g/dL). No differences were found in age, duration of CPD until the first clearance study, percent of subjects with anuria, Kt/V urea, creatinine clearance, blood urea nitrogen, serum creatinine, and PNA normalized to W. Obese CPD patients tend to have better nutrition indices than do normal-weight CPD patients with similar small-solute clearances. In obese subjects, normalization by W creates inappropriately low values for nutrition indices derived from urea nitrogen and creatinine excretion. Normalization of those indices by DW appears preferable.

Risk factor management in stable, insulin-treated patients with Type 2 diabetes: the Diabetes Outcomes in Veterans Study.

OBJECTIVES: Describe the methodologies and study population of the Diabetes Outcomes in Veterans Study (DOVES). RESEARCH DESIGN AND METHODS: Prospective, multicenter, observational study of Southwestern veterans with stable, insulin-treated Type 2 diabetes. Subjects were randomly selected from pharmacy records and were required to be using at least one long-acting insulin preparation daily. Baseline psychosocial evaluations included psychological status, social and cultural barriers to care, self-care behaviors, and vascular disease risk factors. Clinical measurements included self-reported vascular disease, hemoglobin A1c (HbA1c), blood pressure, blood lipids, and body mass index (BMI). A subset of subjects completed a protocol of four times daily self-monitored blood glucose testing for 8 weeks. Subjects were followed for 12 months. Principal endpoints included glycemic control, the occurrence of hypoglycemia, and control of vascular disease risk factors. RESULTS: We enrolled 338 subjects. The mean (+/-S.D.) age was 65.1+/-9.7 years and 3.8% were women. At baseline, over two-thirds of subjects reported vascular disease complications. Nearly three-quarters had limited physical activity. Among subjects younger than 65 years, 53% considered themselves disabled for work. Despite the high prevalence of vascular disease, 43.8% had an HbA1c >/=8.0%. Many subjects were sedentary, 62.1% had a BMI of 30 kg/m(2) or above, and 22.2% were still smoking. CONCLUSIONS: Detailed measurements of psychological status, self-care behaviors, and risk factor control are feasible in this elderly, debilitated population. Although the prevalence of complications and self-rated disability was high, vascular disease risk factors were poorly controlled in a substantial proportion of subjects.

Classification of the degree of obesity by body mass index or by deviation from ideal weight.

BACKGROUND: The purpose of this study was to compare classifications of subjects as underweight, normal weight, or obese by body mass index (BMI) and the ratio of body weight to ideal weight (W/IW). METHODS: We performed a theoretical comparison of the 2 indices. We compared classifications of the degree of obesity in 1839 women and 5914 men who were followed up in the primary care clinics of a United States federal hospital. Information was extracted from computerized records. Subjects were classified as underweight (BMI < 18.5 kg/m2, W/IW < 0.9), obese (BMI > or = 30.0 kg/m2, W/IW > or = 1.2), or normal weight (BMI, W/IW values between the cutoff values for underweight and obesity). W/IW values were computed assuming small, medium, and large skeletal frame for all. We compared the classifications of subjects as underweight, normal weight, or obese by BMI and W/IW. We used Cohen's kappa ratio to evaluate the agreement between these classifications. RESULTS: Theoretically, the cutoff values of BMI and W/IW for underweight and obesity are not in agreement. Patient data revealed substantial differences in the classifications of subjects as underweight, normal weight, or obese. Kappa ratios ranged between 0.18 (poor agreement) and 0.71 (reasonable, but not high degree of agreement). In general, kappa ratios were higher when assuming large or medium skeletal frame versus small frame. CONCLUSIONS: There are substantial discrepancies in classifying the subjects of a population as underweight, normal weight, or obese by BMI or W/IW. These discrepancies may cause confusion when 2 or more indices are used simultaneously to classify the degree of obesity.

Nutrition indices in obese continuous peritoneal dialysis patients with inadequate and adequate urea clearance.

OBJECTIVE: To test whether better nutrition is associated more with adequate urea clearance than with inadequate urea clearance in obese patients on continuous peritoneal dialysis (CPD). DESIGN: Retrospective analysis of clearance and nutrition indices in obese CPD patients. Only obese patients were analyzed. Obesity was defined as a ratio of actual weight to desired weight (W/DW) > or = 1.2. The dose of dialysis was considered adequate at weekly Kt/V urea > or = 2.0. Small solute clearances and nutrition indices were compared between patients with weekly Kt/V urea < 2.0 and patients with weekly Kt/V urea > or = 2.0 at the first clearance study. SETTING: Four university-affiliated and two private dialysis units in Canada and the United States. PATIENTS: A total of 270 CPD patients with W/DW > or = 1.2 at the first clearance study. RESULTS: Among the 270 obese CPD patients, 157 (58.1%) were underdialyzed (weekly Kt/V urea 1.66 +/- 0.22) and 113 (41.9%) had adequate dialysis (weekly Kt/V urea 2.51 +/- 0.47) at the first clearance study. Creatinine clearance values also differed between the underdialyzed and adequately dialyzed obese groups (55.6 +/- 15.2 vs 87.6 +/- 29.8 L/1.73 m2 weekly, respectively, p < 0.001). The underdialyzed group contained fewer women (39.5% vs 60.2%, p < 0.001) and more patients with anuria (35.0% vs 8.8%, p < 0.001), and had higher serum urea (20.7 +/- 6.9 vs 18.2 +/- 5.3 mmol/L, p = 0.001) and serum creatinine (974 +/- 283 vs 734 +/- 275 micromol/L, p < 0.001), marginally lower serum albumin (35.8 +/- 5.2 vs 37.2 +/- 6.4 g/L, p = 0.082), lower urea nitrogen excretion (5778 +/- 2290 vs 7085 +/- 2238 mg/24 hr, p < 0.001) and indices derived from urea nitrogen excretion (protein nitrogen appearance and normalized protein nitrogen appearance), and lower creatinine excretion (1034 +/- 349 vs 1217 +/- 432 mg/24 hr, p < 0.001) and indices derived from creatinine excretion (lean body mass normalized to actual or desired weight) than the adequately dialyzed group. CONCLUSION: Nutrition indices derived from urea nitrogen and creatinine excretion are worse in underdialyzed than in adequately dialyzed obese CPD patients. This finding may have clinical importance, despite the mathematical coupling between small solute clearances and excretion rates in cross-sectional studies, because of evidence from other studies that small solute excretion rate in cross-sectional studies is a robust Independent predictor of outcome in CPD.
