Efficacy of Chemotherapy Combinations in Metastatic Castration-Resistant Prostate Cancer Patients - Do Homologous Recombination Deficiency Affect the Outcomes?
Journal Title: The Bulletin of Urooncology - Year 2020, Vol 19, Issue 4
Abstract
Homologous recombination (HR) is a major repair mechanism of DNA damage. Platin-based agents are known to be more effective in patients with impaired HR mechanism. Previous studies combined platin compounds with docetaxel, but most of these studies did not perform subgroup analysis for HR-deficient patients. Aggressive variant prostate cancer (AVPC) is considered more susceptible to carboplatin. Furthermore, prostate cancers with a higher rate of small cell or anaplastic carcinoma components are more susceptible to carboplatin plus etoposide. We thought that the effect of cabazitaxel plus carboplatin on the progression-free survival might be related to carboplatin alone. In a study that evaluated the effect of cabazitaxel plus carboplatin, the proportion of AVPC patients was higher in the combination group than in the cabazitaxel group. Additionally, the combination of cabazitaxel and carboplatin led to increased toxicity.

Experiences of Laparoscopic Partial Nephrectomy for T1a Kidney Tumours: Results of Two Hundred and Fifteen Patients
Objective: The best therapeutic option for renal tumours smaller than 7 cm is partial nephrectomy. The aim of this study was to compare the positive surgical margin (PSM) rates, recurrence rates and oncological outcomes...
Comparative Usefulness of High-frequency Doppler Ultrasonography, Serum PSA Density, and Free to Total Serum PSA Ratio in the Prediction of Prostate Cancer
Objective: In this study, we tried to assess whether power Doppler ultrasonography (PDU) evaluation along with transrectal ultrasound (TRUS) has an additional benefit in the diagnosis of prostate cancer in patients with...
Oncological Outcomes of Bilateral Testicular Germ Cell Tumors and Evaluation of Prognostic Risk Factors
Objective: The incidence of bilateral testicular germ cell tumours (TGCT) is low and constitutes 0.5%-7% of all testicular tumours. We aimed to evaluate the clinical and pathological features of unilateral and bilateral...
Laparoscopic Adrenalectomy: Assessment of the Surgical Outcomes and Learning Curve for Large Adrenal Tumours
Objective: Laparoscopic adrenalectomy (LA) is the treatment of choice for benign tumours of less than 6 cm. However, there is still an ongoing debate regarding the exact cut-off value of the tumour size. The aim of this...
Contemporary Trends in Adrenal Sparing Surgery
Adrenal gland surgery has been practiced by the urologists ever increasingly in line with their interest in this particular field. Total adrenalectomy which is the classical approach for adrenal masses, is replaced by th...
