The course of quality of life and neurocognition in newly diagnosed patients with glioblastoma.

BACKGROUND: The importance of QoL and neurocognitive functions in patients with glioblastoma (GB) is above controversy by now. We followed newly diagnosed GB patients treated with radio-chemotherapy during their course of disease by continuously evaluating their quality of life (QoL) and cognitive functions. METHODS: We included consecutive patients with newly diagnosed GB from 2010 to 2013 at the Medical University of Vienna. To assess QoL the EORTC QLQ C30 and BN20 questionnaire were used. Neurocognition was measured with the NeuroCog FX. The evaluations were done 6 times every three months, beginning at the beginning of radio-chemotherapy. RESULTS: 42 patients participated in this study. We also recorded QoL and neurocognition in 23 patients after the first disease progression. Patients maintained their cognitive summary score until relapse. Patients with left-sided tumors showed significant lower scores in the subscale verbal fluency than patients with right-sided tumors. The global health score of QoL decreased after the fifth evaluation (13months after diagnosis) whereas a peak of fatigue symptoms was obtained at the third evaluation. Furthermore, fatigue symptoms increased strongly 7months after diagnosis and patients' financial difficulties were mentioned more frequently by younger patients and in patients with lower education levels. CONCLUSIONS: QoL and cognitive long-term assessments are feasible also in some patients with GB after a symptomatic progression. Our study demonstrates maintenance of QoL and cognitive summary scales before tumor progression. Moreover, it highlights subgroups according to tumor location and socioeconomic factors.

Androgen receptor expression is associated with adverse pathological features in ureteral but not in pelvicalyceal urothelial carcinomas of the upper urinary tract.

PURPOSE: This study aims to determine the significance of androgen receptor (AR) expression in urothelial carcinoma of the upper urinary tract (UTUC). METHODS: AR expression was assessed on tissue microarrays containing specimens of 737 patients with UTUC who underwent radical nephroureterectomy with curative intent. AR expression was correlated with clinical and pathological tumor features as well as recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). RESULTS: Overall, AR was expressed in 11 % of tumors. AR expression was significantly associated with tumor necrosis as well as sessile and multifocal tumor growth but not with RFS, CSS or OS. AR was detected nearly twice as often in tumors of the ureter than of the pelvicalyceal system (p = 0.005). Subgroup analyses showed that the significant associations of AR with unfavorable pathologic features were exclusively attributable to tumors located in the ureter. However, in both ureteral and pelvicalyceal tumors, AR status was independent of RFS, CSS and OS. CONCLUSIONS: In this cohort of patients treated with RNU, AR expression was found in approximately 10 % of UTUCs, twice as often in ureteral than in pelvicalyceal tumors. While AR expression had no impact on postoperative prognosis, it was significantly associated with unfavorable pathologic features in ureteral tumors. Steroid hormone signaling might be relevant for future investigations of differences between ureteral and pelvicalyceal tumors.
