Cancers, Vol. 11, Pages 1719: Plasma Androgen Receptor in Prostate Cancer Cancers doi: 10.3390/cancers11111719 Authors: Vincenza Conteduca Giorgia Gurioli Nicole Brighi Cristian Lolli Giuseppe Schepisi Chiara Casadei Salvatore Luca Burgio Stefania Gargiulo Giorgia Ravaglia Lorena Rossi Amelia Altavilla Alberto Farolfi Cecilia Menna Sarah Pia Colangione Mario Pulvirenti Antonino Romeo Ugo De Giorgi The therapeutic landscape of prostate cancer has expanded rapidly over the past 10 years, and there is now an even greater need to understand the biological mechanisms of resistance and to develop noninvasive biomarkers to guide treatment. The androgen receptor (AR) is known to be involved in the pathogenesis and progression of prostate cancer. Recently, highly sensitive next-generation sequencing and PCR-based methods for analyzing androgen receptor gene (AR) copy numbers (CN) and mutations in plasma were established in cell-free DNA (cfDNA) of patients with castration-resistant prostate cancer (CRPC) treated with different drugs. The study of cfDNA holds great promise for improving treatment in CRPC, especially in the advanced stage of the disease. Recent findings showed the significant association of plasma AR aberrations with clinical outcome in CRPC patients treated with AR-directed therapies, whereas no association was observed in patients treated with taxanes. This suggests the potential for using plasma AR as a biomarker for selecting ...

Abstract OBJECTIVE: Docetaxel has been shown to be an effective chemotherapy agent when combined with androgen deprivation therapy for hormone sensitive metastatic prostate cancer (CaP). Since very high risk CaP has a high rate of occult metastatic disease and early recurrence, we hypothesize that patients with very high risk locally advanced CaP may benefit from docetaxel-based neoadjuvant chemohormonal therapy (NCHT). Thus, we conducted a retrospective study to identify the outcome of these patients treated with NCHT followed by radical prostatectomy (RP). PATIENTS AND METHODS: We retrospectively analyzed d...

Abstract We investigated the effectiveness of 11C-choline-positron emission tomography/computed tomography (PET/CT) for evaluating treatment response in patients with prostate cancer or renal cell carcinoma. We performed 34 11C-choline PET/CT scans before/after a combined total of 17 courses of treatment in 6 patients with prostate cancer and 2 with renal cell carcinoma. The 17 treatments including hormonal therapy, radiotherapy, chemotherapy, radium-223, molecular target therapy, radiofrequency ablation, transcatheter arterial embolization, and cancer immunotherapy yielded 1 (5.9%) complete metabolic response (CM...

This article investigates how Black South Africans residing in Soweto, a township of Johannesburg, perceive and experience breast and prostate cancers amidst multiple, concurrent medical conditions. We used convenience sampling to recruit 80 study participants already enrolled in longitudinal studies of breast and prostate cancers at a tertiary hospital in Soweto between June and August 2017. This included 50 women diagnosed with breast cancer and 30 men diagnosed with prostate cancer; three-quarters of the sample had two or more comorbidities, including HIV, hypertension, diabetes, anxiety, and others. Many described sick...

Authors: Latorzeff I Abstract Prostate cancer is a sensitive adenocarcinoma, in more than 80 % of cases, to chemical castration, due to its hormone dependence. Locally advanced and/or high-risk cancer is defined based on clinical stage, initial PSA value or high Gleason score. Hormone therapy associated with radiation therapy is the standard of management and improves local control, reduces the risk of distant metastasis and improves specific and overall survival. Duration of hormone therapy, dose level of radiation therapy alone or associated with brachytherapy are controversial data in the literature. Radical pro...

Authors: Houédé N Abstract To date, systemic treatments, including hormone therapies or chemotherapy, are used at different stages of prostate cancer disease. Several types of complications can occur during systemic treatment in prostate cancer, depending on the therapeutic range. The most common with hormone therapy are fatigue, muscle loss, bone loss, high blood pressure and metabolic syndromes. For chemotherapy, the most significant risk is related to hematological toxicity, but peripheral neuropathies, mucositis, diarrhea and hypersensitivity reactions may also occur. The quality of the pre-treatm...

Authors: Miranda J, Viñal D, Pinto Á Abstract The treatment of patients with metastatic castration-resistant prostate cancer (mCRPC) has evolved dramatically in the recent years with the approval of several new drugs. Together with other treatment modalities including chemotherapy, hormonal therapy and immunotherapy, radiopharmaceuticals have recently been incorporated to the therapeutic scenario of prostate cancer with the approval of Radium 223 dichloride (Ra-223) for the treatment of mCRPC patients with symptomatic bone metastasis and no visceral metastases. Radiopharmaceuticals have long been used...

Conclusion: Clinical studies in breast cancer patients from Asia have primarily investigated the effect of leuprorelin on the protection of ovarian function in patients who receive chemotherapy, assessed the ability of leuprorelin to suppress serum estradiol to menopausal levels, or to determine the efficacy and safety of leuprorelin in daily medical practice.
