Prospective analysis of patient reported symptoms and quality of life in patients with incurable lung cancer treated in a rapid access clinic.

INTRODUCTION: The Vancouver Rapid Access (VARA) clinic was designed to provide palliative radiotherapy and holistic care to patients with incurable lung cancer. Analysis of the pilot phase demonstrated improved radiotherapy wait-times and access to supportive services compared to standard practice. This study aims to prospectively assess the impact of the clinic on patient reported symptoms and quality of life. MATERIALS AND METHODS: Patient assessments are completed at baseline and by a telephone follow up four-weeks later using Likert scales adapted from the Edmonton Symptom Assessment System (scale 0-10) and European Organization for Research and Treatment of Cancer questionnaires (scale 1-4). Patient reported outcomes at follow-up are compared to baseline using wilcoxon signed-rank test for categorical variables and paired sample t-test for continuous variables. RESULTS: Baseline data was collected on 125 patients, 109 received palliative radiotherapy (87%). At the 4 week follow up, 22 patients had died. Seventy-one of the remaining 103 patients completed the follow-up questionnaire, resulting in a 69% response rate among survivors. The mean patient reported overall health score, improved from 4.8 to 6.1 (p<0.01). All respiratory symptoms except chest pain (p=0.06) were associated with a statistically significant improvement after the clinic, whereas all respiratory symptoms improved post radiotherapy. Mean bone pain scores decreased from 5.5 to 2.7 (p<0.01). Assessment of symptoms secondary to brain metastases is limited by small patient numbers. CONCLUSION: The VARA clinic provides timely access to palliative radiotherapy and supportive services resulting in improved patient reported outcomes. Despite a high symptom and disease burden, patients report improved overall health and palliation of respiratory symptoms and bony pain. The studies completed on the VARA clinic to date, continue to support its value in our center.

Testosterone recovery following prolonged adjuvant androgen ablation for prostate carcinoma.

BACKGROUND: This study was conducted to describe the rate and completeness of the recovery of testosterone production following prolonged temporary androgen ablative therapy in men with prostate carcinoma undergoing curative radiation therapy. METHODS: Two-hundred and sixty-seven men treated with between 3 months and 3 years of adjuvant androgen ablation (AA) were followed at 6-month intervals following cessation of their androgen deprivation therapy. A comparative group of 518 men not undergoing AA were also followed. RESULTS: Drugs used included low dose cyproterone/stilboestrol (CPA/DES) in combination (56%) and 1 month depot (18%) and 3 month depot (25%) leutinizing hormone releasing hormone agonist (LHRHa). Seventy-nine percent of men in the current study recovered normal testosterone levels (10nmol/L), and 93% recovered levels of at least 5nmol/L. In comparison, men who had never received androgen ablative therapy showed a fall of testosterone, with 17% having sub-normal levels after 3 years. Median time to testosterone recovery was 10 months. Factors associated on multivariate analysis with delayed testosterone recovery included advanced age (P = 0.008), low pre-therapy testosterone (P = 0.04), and the use of 3 month LHRHa preparations as compared with CPA/DES (P = 0.002) or 1 month LHRHa preparations (P = 0.015). The duration of drug use was not significantly associated with time to testosterone recovery. CONCLUSIONS: Long-acting LHRHa preparations appear to have a more prolonged action than previously supposed. Most men treated for up to 2 years recover normal testosterone levels after cessation of adjuvant androgen ablation, and the limited data available in the current study on patients treated for 3 years also suggests most will recover.
