Androgen deprivation therapy (ADT; also known as hormone therapy) is a well-established treatment for prostate cancer patients with rising prostate-specific antigen levels after localized treatment, and for those with metastatic disease. The neurological impact of ADT has been likened to that of aging and is therefore theorized to impair cognitive functioning in prostate cancer patients. We briefly summarize the research that has examined cognitive functioning of ADT patients primarily through neuropsychological assessment. A qualitative pilot study is presented with the aim of describing ADT patients' experiences of cognitive changes since starting ADT. ⋯ The interviews illustrate the potential negative effects of ADT on cognitive and neurobehavioral functions, and their impact on patients' work and in their daily lives. We describe how the field of cognitive rehabilitation offers promising tools to assist ADT patients with cognitive problems.

To evaluate the efficacy and safety of targeted agents (sorafenib and sunitinib) as postoperative adjuvant therapy in Chinese patients with clear cell renal cell carcinoma (CC-RCC) who are at high risk for disease recurrence. ⋯ Targeted adjuvant therapy postoperatively with sorafenib or sunitinib in patients with CC-RCC who are at a high risk for disease recurrence was well tolerated and effective in reducing the rate of CC-RCC recurrence in these patients. This study is an attempt to assess the utility of adjuvant tyrosine kinase inhibitors (TKIs) after surgery for renal carcinoma. The apparently improved outcomes, compared with a historical control population, are of sufficient interest to support the continuation of an ongoing randomized clinical trial to validate the hypothesis.

To evaluate the outcomes of radical prostatectomy (RP) and pelvic lymph node dissection (PLND) for clinically organ confined prostate cancer (CaP) with regional lymph node metastases (pN1) treated in the era of prostate-specific antigen (PSA) screening. ⋯ The incidence of pN1 in patients with cT1-T2 CaP treated with surgery in the era of PSA screening was low. RP and PLND demonstrated therapeutic efficacy in a subset of pN1 patients treated with surgery alone.

Sarcomatoid metastatic renal cell carcinoma (mRCC) represents an aggressive subset of disease, and a definitive therapeutic strategy is lacking. We seek to define outcomes associated with systemic therapy (including immunotherapy, cytotoxic therapy, and targeted agents) for sarcomatoid mRCC, with attention to novel prognostic schema. ⋯ Compared with previous series and prospective trials assessing patients with sarcomatoid mRCC, the observed survival was prolonged. Although both Heng and MSKCC risk scores may be useful in determining prognosis, further studies are needed to identify relevant biomarkers and define the optimal therapeutic strategy for this disease.

Abiraterone acetate, an androgen biosynthesis inhibitor, improves overall survival in patients with metastatic castration-resistant prostate cancer after chemotherapy. We evaluated this agent in patients who had not received previous chemotherapy. ⋯ Abiraterone improved radiographic progression-free survival, showed a trend toward improved overall survival, and significantly delayed clinical decline and initiation of chemotherapy in patients with metastatic castration-resistant prostate cancer.
