    The Rate of Neoadjuvant Chemotherapy Use in Muscle Invasive Bladder Cancer and The Approach of Urologists in Turkey
    Ucer, O; Albaz, AC; Atag, E; Karaoglu, A; Muezzinoglu, T
    Purpose: To investigate the proportion of neoadjuvant chemotherapy (NAC) use in patients with muscle invasive bladder cancer before radical cystectomy and the approach of urologists to this subject. Materials and Methods: We invited 242 urologists during the 12th International Urooncology Congress in Turkey to answer a self-administered questionnaire. The questionnaire included questions related to radical cystectomy, lymph node dissection and neoadjuvant chemotherapy that had been performed in patients with muscle invasive bladder cancer by the urologist. Results: The median number of radical cystectomy operations was 20 per year. 122 (50.5 %) of 242 urologists had used neoadjuvant chemotherapy for the treatment of muscle invasive bladder cancer before radical cystectomy. The mean rate of neoadjuvant chemotherapy use by these urologists (n=122) was 28.46 %. The most common reasons for not using neoadjuvant chemotherapy by urologists in Turkey were as follows: (i) neoadjuvant chemotherapy might lead to a decrease in the cure rate of radical cystectomy due to delayed surgery (ii) complication rate of radical cystectomy might be elevated and the surgery might be complicated by NAC use. Conclusion: Although the European Association of Urology (EAU) guidelines panel on muscle invasive bladder cancer recommends using NAC in T2-T4a bladder, the rate of neoadjuvant chemotherapy use was still found to be low in our country because urologists have concerns about adverse effects NAC on radical cystectomy.

    What Is Your Choice for Androgen Deprivation Therapy in Metastatic Prostate Carcinoma: Surgical or Medical?

    Objective: At the time of diagnosis, approximately 16.5% of prostate cancer patients are metastatic. The main framework of metastatic prostate cancer treatment is androgen deprivation therapy, which is performed surgically or medically. The aim of this study is to evaluate the attitudes of medical oncologists and urologists about orchiectomy as androgen deprivation therapy. Material and Methods: A total of 387 physicians working in the Departments of Urology (n = 217) and Medical Oncology (n = 170) were included in this descriptive study. Data were collected through an electronic survey. Results: Only 7.5% of participants indicated that they offered surgical castration to their patients. Urologists preferred surgical castration more than oncologists for the treatment of metastatic castration-sensitive prostate carcinoma (P = .003). The reasons why medical oncologists preferred surgical castration less are that it is an invasive procedure, has risk of morbidity and mortality, high cost of hospitalization, and may cause deterioration of the patient's body image (P < .05). Conclusion: This study showed that physicians were less likely to perform orchiectomy as an androgen deprivation therapy. Although the most important reason for this is the patient preference, the biased presentation of treatment options to patients, the lack of knowledge of physicians about orchiectomy, and the effect of the pharmaceutical industry should also be kept in mind.
