Quality of Life in Men With Prostate Cancer Randomly Allocated to Receive Docetaxel or Abiraterone in the STAMPEDE Trial.

PURPOSE: Docetaxel and abiraterone acetate plus prednisone or prednisolone (AAP) both improve survival when commenced alongside standard of care (SOC) androgen deprivation therapy in locally advanced or metastatic hormone-sensitive prostate cancer. Thus, patient-reported quality of life (QOL) data may guide treatment choices. METHODS: A group of patients within the STAMPEDE trial were contemporaneously enrolled with the possibility of being randomly allocated to receive either docetaxel + SOC or AAP + SOC. A mixed-model assessed QOL in those who had completed at least one QLQ-C30 + PR25 questionnaire. The primary outcome measure was difference in global-QOL (QLQ-C30 Q29&30) between patients allocated to docetaxel + SOC or AAP + SOC over the 2 years after random assignment, with a predefined criterion for clinically meaningful difference of > 4.0 points. Secondary outcome measures included longitudinal comparison of functional domains, pain, and fatigue, plus global-QOL at defined timepoints. RESULTS: Five hundred fifteen patients (173 docetaxel + SOC and 342 AAP + SOC) were included. Baseline characteristics, proportion of missing data, and mean baseline global-QOL scores (docetaxel + SOC 77.8 and AAP + SOC 78.0) were similar. Over the 2 years following random assignment, the mean modeled global-QOL score was +3.9 points (95% CI, +0.5 to +7.2; P = .022) higher in patients allocated to AAP + SOC. Global-QOL was higher for patients allocated to AAP + SOC over the first year (+5.7 points, 95% CI, +3.0 to +8.5; P < .001), particularly at 12 (+7.0 points, 95% CI, +3.0 to +11.0; P = .001) and 24 weeks (+8.3 points, 95% CI, +4.0 to +12.6; P < .001). CONCLUSION: Patient-reported QOL was superior for patients allocated to receive AAP + SOC, compared with docetaxel + SOC over a 2-year period, narrowly missing the predefined value for clinical significance. Patients receiving AAP + SOC reported clinically meaningful higher global-QOL scores throughout the first year following random assignment.

Clinical outcomes in patients with T4 laryngeal cancer treated with primary radiotherapy versus primary laryngectomy.

BACKGROUND: The purpose of this study was to determine the clinical outcomes of T4 laryngeal cancers. METHODS: T4 laryngeal cancers treated with curative intent from January 2003 to December 2010 were analyzed. Outcomes were evaluated in both primary radiotherapy (+/- chemotherapy) (RT/CRT) and primary surgery cohorts. RESULTS: Among the 65 primary RT/CRT and 42 primary surgery patients included, median follow-up was 4.4 years. There was a trend for improved locoregional control with surgery (74% vs 88%; p = .08). In the RT/CRT group the 3-year laryngectomy-free survival was 67%. The 2-year gastrostomy dependency rate was 23% with RT/CRT versus 6% with primary surgery (p = .07). Overall survival (OS) at 3 years was significantly lower in the RT/CRT versus primary surgery group (41% vs 70%; p < .01). CONCLUSION: Laryngeal preservation is achieved in over two thirds of patients with primary RT/CRT. Patients with low volume minimal cartilage involvement T4 disease may be best suited to RT/CRT. © 2016 Wiley Periodicals, Inc. Head Neck 38: E2035-E2040, 2016.

Use of radionuclides in metastatic prostate cancer: pain relief and beyond.

PURPOSE OF REVIEW: Bone metastases in prostate cancer are often the cause of significant morbidity in patients with castrate-resistant disease, and several studies have shown significant pain palliation with systemic radionuclide treatment. The purpose of this review is to discuss the place of radionuclides in the dynamic treatment landscape of metastatic prostate cancer in light of new evidence demonstrating benefit beyond palliation. RECENT FINDINGS: The recently reported ALSYMPCA trial, which was a multicentre, placebo-controlled, phase 3 randomized controlled trial in patients with symptomatic metastatic castrate-resistant prostate cancer (CRPC) has shown significant overall survival (OS) benefit in favour of Radium-223 (Alpharadin) treatment [median OS 14.0 vs. 11.2 months; P = 0.00185; hazard ratio 0.695; 95% confidence interval (CI) 0.552-0.875]. This situation led to early unblinding of the trial and patients on placebo arm being offered Radium-223 treatment. SUMMARY: It has been an exciting and challenging time for treatment of patients with metastatic CRPC with six new agents demonstrating OS benefit in phase 3 trials, in this setting since 2004. Further research should focus on appropriate sequencing and innovative strategies to use these therapeutic agents to maximize benefit for patients. In the case of radionuclides, novel strategies include repeated administration, dose intense regimens and combination with other agents.
