Quality of life in patients with prostatic carcinoma: a review and results of a study in N+ disease. Prostate-specific antigen as predictor of quality of life.

Clinical evaluation in oncology has typically focused on outcome indicators, while less attention has been paid to how treatment affects quality of life (QOL) of the patient. In this article some general aspects of quality of life are discussed, a short review of published data on QOL in patients with prostate cancer is given and results of a QOL study executed by the authors on patients with lymph node positive prostatic cancer are presented. The purpose of the study was to examine the impact of immediate or delayed treatment (after objective progression) in patients with prostatic carcinoma (T1-3 N1-3 M0) on quality of life parameters. To this end an extended questionnaire was constructed. Fifty-five patients participated. Assessment was performed twice, in 1994 and 1995. The comparison between patients with and patients without treatment showed in 1994 as well as in 1995 significant differences for hormonal treatment side effects such as sexual functioning and hot flushes, all of which were experienced more frequently by treated patients. In 1994 the treated patients experienced more psychological distress while in 1995 they showed worse physical function, less energy and more fatigue when compared to patients under surveillance. The premise that active treatment would improve the psychological quality of life was not sustained. In addition global health status and quality of life were identified as independent factors for progression in untreated patients with lymph node positive prostate cancer. Finally, an increase in prostate-specific antigen (PSA) in hormonally treated patients not only indicated hormonal escape but also a decrease in QOL.

Health-related quality of life and psychosocial factors in patients with prostate cancer scheduled for radical prostatectomy or external radiation therapy

To assess whether baseline health‐related quality of life (HRQOL) and psychosocial profiles differ in patients with prostate cancer scheduled for radical prostatectomy (RP) or external radiation therapy (ERT), as there is evidence that HRQOL is influenced by psychosocial factors (PFs), so that any variation at baseline should be considered when comparing the effect of therapy on HRQOL.

Quality of life assessment in patients with hormone-resistant prostate cancer treated with epirubicin or with epirubicin plus medroxy progesterone acetate: is it feasible ?

Objectives: The optimal palliative treatment in patients with advanced hormone–resistant prostate cancer (AHRPC) is still under investigation. We studied the effect of epirubicin, alone or combined with medroxy progesterone acetate (MPA), in this particular patient group. The aim of the study was to investigate the feasibility of quality of life (QOL) measurement and to ascertain whether MPA added to epirubicin produces a better QOL than epirubicin alone.Methods: Of 28 randomized patients with symptomatic AHRPC, 26 were eligible for the study. Fourteen of them received epirubicin (100 mg/m2 i.v.) every 3 weeks in combination with an oral dose of 500 mg of MPA twice daily. Twelve patients received epirubicin alone. For the QOL assessment, the Rotterdam Symptom Checkliste was used. Toxic side effects of chemotherapy were assed by the WHO criteria. Subjective responses included performance status and pain score.Results: Compliance in completing QOL questionnaires was high (87.5%). In none of the QOL domains studied did any of the patients, irrespective of their treatment, experience an improvement in their QOL. Moreover, after 12 and 24 weeks, patients in both treatment arms experienced a significant worsening of physical symptom distress when compared to study entry. Toxicity was moderate to severe. A biochemical response (drop in prostate–specific antigen of more than 50%) was observed in 5 out of 26 patients (19.1%) and a subjective response in 7 out of 26 patients (26.9%). The median survival for all patients was 30 weeks. There was no statistically significant difference between the two arms. Performance status and the global QOL as judged by the patients themselves were associated with the duration of survival. No relation was found between the initial observed subjective response and survival.Conclusions: The feasibility of measuring QOL in patients with symptomatic AHRPC is demonstrated in the present study. Subjective and biochemical responses were observed in both treatment arms, but these were not translatable as improved measured QOL domains.

Does prostate-specific antigen density alter decision making on biopsy?

OBJECTIVE The ability of prostate-specific antigen density (PSAD) to predict prostate cancer in biopsy specimens is evaluated in patients with benign digital rectal examination (DRE) and prostate-specific antigen (PSA) between 4.0 and 10.0 ng/ml. MATERIAL AND METHODS 144 referred patients with a benign DRE and PSA > 4.0 ng/ml were additionally evaluated by transrectal ultrasonography and transrectal biopsies. PSAD values were calculated and statistical analysis was performed. RESULTS The mean PSAD value was able to distinguish significantly between benign prostate conditions and prostate cancer in patients with PSA > 4.0 ng/ml. However, in 73 patients with 4.0 < PSA < or = 10.0 ng/ml no significant stratification was obtained. At a PSAD value of 0.15 the pretest probability of 18% for positive biopsy was lowered to a posttest probability of 8.1% and PSAD appeared to be of limited value regarding sensitivity and specificity at different cutoff values (ROC curve). Applying age-specific reference ranges would have reduced diagnostic procedures for men between 60 and 79 years old with 7.0% without missing prostate cancer. CONCLUSIONS In this study PSAD was shown to have only a moderate additive value in decision making to omit biopsy for the individual patient with benign DRE and PSA between 4.0 and 10.0 ng/ml. Age-specific reference ranges of PSA can prevent unnecessary diagnostic procedures.
