PCA3, as a therapeutic target in PCa, might be used to potentiate AR antagonists.

Backround and purpose To investigate the incidence of complications related to propofol-based anesthesia and the factors associated with complications in children with radiotherapy. Materials and methods Patients who underwent anesthesia for external beam radiotherapy between May 2013 and November 2017 were included in the study. We assessed the age/weight, sex, oncologic diagnosis, type of radiotherapy procedure, duration of anesthesia, applied agents, and complications related to anesthesia. Complications were evaluated between group I (only propofol group) and group II (propofol plus adjuvant drugs) as respiratory and cardiac. Results In 130 patients, sedation was given for 1376 radiotherapy procedures. Of these, 1274 (1140 radiation treatment sessions and 134 computed tomography simulations) in 126 patients were propofol-based and were included in the analysis. Although respiratory complications are the most common in both groups, there were no episodes of laryngospasm, broncospasm, and no use of advanced airway intervention. The rate of complication was significantly higher in only propofol anesthesia group than in patients treated with propofol plus adjuvant drugs. In the multivariate analysis, we found three factors that were significantly associated with the risk of complications: total dose of propofol (mg/kg) (p < 0.001), anesthesia with propofol alone (as compared to propofol plus adjunct agents) (p = 0.001), and diagnosis of neuroblastoma (as compared to other diagnosis) (p = 0.043). Conclusion Propofol-based anesthesia is preferred in order to minimize the rate of complications in radiotherapy anesthesia applications. The use of non-opioid adjuvants in combination with propofol to achieve a balanced anesthesia will also reduce the complications that may be encountered.

Background. Granulocytic sarcoma (GS) is an extramedullary solid tumor composed of immature myeloid cells. GS has been associated with acute myeloid leukemia (AML), myelodysplastic syndromes or myeloproliferative diseases. Although GS can affect various tissues of the human body, it has rarely been reported in other soft tissues such as the breast, gastrointestinal, respiratory and genitourinary tracts. We report a pediatric case diagnosed with granulocytic sarcoma of the bladder and concomitant AML.Case. A twelve-year-old previously healthy girl was admitted to the pediatric urology clinic with a ten-day history of hematuria and pollakiuria. Laboratory examinations revealed anemia, thrombocytopenia and neutrophilic leukocytosis. Bone marrow aspiration results were consistent with acute myeloid leukemia -FAB subtype M2-. Abdominal magnetic resonance imaging (MRI) showed an irregularly bounded 12 cm mass on the right side of the bladder. Transurethral resection (TUR) pathology was consistent with granulocytic sarcoma. After a multimodal treatment approach, complete remission was achieved. Conclusions.Malignant bladder masses are rare causes of macroscopic hematuria in childhood. The diagnostic spectrum is wide, ranging from rhabdomyosarcoma to leukemia involvement. The bladder is a rare site of extramedullary involvement in pediatric patients with AML. Multimodal treatment should be considered on a per-patient basis.
