Efficacy, tolerance and predictors of response to the treatment with hyperbaric oxygen therapy for patients with hemorrhagic radiation cystitis.

OBJECTIVES: The aim was to study the efficacy and tolerance in patients with haemorrhagic radiation-induced cystitis (HRC) treated with hyperbaric oxygen therapy (HOT) and analyze which factors were related to the response to the treatment. MATERIAL AND METHODS: We performed a retrospective cohort study of patients treated with HOT for HRC symptoms in a provincial referral centre from 2010 to 2020. We evaluated clinical response to treatment, number of hospitalizations due to HRC and subjective response using the PGI-I questionnaire. RESULTS: We treated 52 patients, with a median of 30 sessions, during 6 months and 40 months (6-68 months) of follow-up. 69.2%of patients responded completely and 21,2% partially. The 53.2% of patients improved before the first 10 sessions. Reduction of hospitalizations/per year due to haematuria from 2.8 to 1.1 (p=0,001). The 73,5% of patients stated that they were "very much better" or "much better" after treatment. During the follow-up, 15.4% of patients had recurrence of HRC. 9.6% of the patients required salvage cystectomy. The patients with a highest RTOG-EORTC scale had more risk to still with symptoms (OR 3.01 (IC95 1.48 - 6.16). All patients were able to complete the proposed treatment plan with good tolerance to HOT. CONCLUSIONS: These results show the clinical benefit of HOT in the treatment of HRC, with a reduction of the number of hospitalizations and a subjective improvement.

Terapia de deprivación androgénica en cáncer de próstata avanzado. Estudio multicéntrico / Androgen deprivation therapy in advanced prostate cancer. Multicenter study

OBJETIVO: El cáncer de próstata (CP) avanzado es una entidad frecuente. Los objetivos de este trabajo son la presentación de una serie de pacientes con CP en tratamiento con Terapia de Deprivación Androgénica (TDA) en práctica clínica habitual y la determinación de parámetros asociados al desarrollo de resistencia a la castración (CPRC). MATERIAL Y MÉTODOS: Estudio multicéntrico, observacional, retrospectivo que analiza pacientes tratados con TDA desde enero 2016 hasta enero 2017. Análisis descriptivo de las variables clínicas más relevantes, análisis univariante y supervivencia libre de progresión mediante test Kaplan-Meier. RESULTADOS: Muestra 952 pacientes. Al diagnóstico del CP edad mediana 74 años. Mediana de PSA al diagnóstico de CP 23 ng/ml, al inicio TDA 20,2 ng/ml. El 80,2% de pacientes tenían biopsia al diagnóstico del CP: 28,2% grado pronóstico Gleason grupo 1, 38,7% grados 2 y 3 y 33,1% grados 4 y 5. Tratamiento inicial del CP: 75,9% TDA, prostatectomía radical 8,4% y radioterapia 15,1%. De los 952 pacientes, 281 (29,6%) cumplían criterios de CPRC. En este grupo el 21,7% alcanzó PSA indetectable (<0,1 ng/ml) con la TDA 20,2 frente al grupo no CPRC en el que lo alcanzaron el 59,9%. Encontramos mayor probabilidad de progresión a CPRC en pacientes con PSA al diagnóstico de CP > 30 ng/ml (p = 0,000, OR 2,78), grado pronóstico Gleason grupos 4-5 (p = 0,000, OR 2,33) y en aquellos que no alcanzan PSA indetectable tras TDA (p < 0,01, OR 3,32) variables que se relacionan con los tiempos de progresión a CPRC y especialmente al estadio metastásico. CONCLUSIONES: Se presenta una serie de pacientes CP avanzado en tratamiento con TDA que muestra heterogeneidad de características y de manejo según práctica clínica habitual. En nuestra serie el PSA elevado al diagnóstico, histología desfavorable y no alcanzar un PSA< 0,1 ng/ml tras la TDA se presentan como indicadores de progresión a estadio CPRC

OBJECTIVES: Advanced prostate cancer (PC) is a frequent entity. The objectives of this paper are the presentation of a sample of patients with PC undergoing treatment with androgen deprivation therapy (ADT) in usual clinical practice and the determination of parameters associated with the development of resistance to castration (CRPC). MATERIAL AND METHODS: Multicenter, observational, retrospective study that analyzes patients treated with ADT from January 2016 to January 2017. Descriptive analysis of the most relevant clinical variables and univariante analysis and progression times by Kaplan-Meier test. RESULTS: Sample of 952 patients. At PC diagnosis median age 74 years. Median PSA at PC diagnosis 23 ng/ml, when begining ADT 20.2 ng/ml. 80.2% of patients were biopsied at PC diagnosis: 28.2% Gleason score group 1, 38.7% groups 2 and 3 and 33.1% groups 4 and 5. Initial treatment of PC: 75.9% ADT, radical prostatectomy 8.4% and radiotherapy 15.1%. Of the 952 patients, 281 (29.6%) fulfilled CRPC criteria. In this group 21.7% achieved undetectable PSA (< 0.1 ng/ml) with ADT compared to the non-CRPC group in which it was 59.9%. Increased probability of progression to CRPC in: PSA >30ng/ml at PC diagnosis (p = 0.000, OR 2.78), Gleason score group 4-5 (p = 0.000, OR 2.33), and not to reach undetectable PSA after ADT (p < 0.001, OR 3.32). The initial ADT group presents progression to metastatic CRPC more rapidly in unfavourable histology and when not reached undetectable PSA after ADT. CONCLUSIONS: We present a sample of patients with advanced PC in treatment with ADT that shows heterogeneity in usual clinical practice. In our sample, elevated PSA at PC diagnosis, unfavorable histology and failure to achieve a PSA <0.1ng/ml after ADT is presented as an indicator of progression to the CRPC stage

Lateral-based Anterior Vaginal Wall Flap in the Treatment of Female Urethral Stricture: Efficacy and Safety.

BACKGROUND: Female urethral stricture is a rare condition. Different types of urethroplasty have been described. However, high quality studies are sparse. The most common technique used-the Blandy's technique-has resulted in our cases in a retrusive meatus and an inward urinary stream. OBJECTIVE: To show the efficacy and safety of an alternative vaginal wall flap urethroplasty. DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional observational study was undertaken in a single University Hospital. Nine female patients previously diagnosed with urethral stricture at our institution underwent open surgery from 1993 to 2015. They were contacted and agreed to undergo a medical examination. SURGICAL PROCEDURE: A ventral lateral-based anterior vaginal wall flap urethroplasty inspired by the Orandi technique for male urethroplasty was performed. MEASUREMENTS: A chart review was performed. RESULTS AND LIMITATIONS: The mean age was 56 yr (41-78 yr). The mean follow-up was 80.7 mo (12-198). All patients had relief of symptoms. The meatus of all patients stayed in an orthotopic position without any impact on the direction of the urinary stream. The average caliber of the urethra increased from 10.8 Fr (6-18 Fr) to ≥20 Fr. Peak flow improved from a mean of 6.8ml/s (3-11ml/s) to 21ml/s (14-35ml/s). No patient developed stricture recurrence or de novo stress urinary incontinence. There were no other immediate or delayed complications. All patients achieved a better score on the Patient Global Impression of Improvement questionnaire. CONCLUSIONS: Our study, with the same limitations that the few studies published in this field had, that is the few patients included, demonstrates that lateral anterior vaginal wall flap urethroplasty is an effective technique, offering durable results without apparent complications. PATIENT SUMMARY: We studied an alternative surgical technique for the treatment of female urethral stricture. We conclude that it is safe and effective with no apparent complications and good long-term results.
