ABSTRACT

INTRODUCTION: The treatment of metastatic castration-resistant prostate cancer (mCRPC) has changed significantly in recent years. Inhibitors of androgen receptors have shown especially significant benefits in overall (OS) and progression-free survival (PFS), with a good toxicity profile. Treatment selection depends on the patient's individual clinical, radiological, and biological characteristics. OBJECTIVE: To describe treatment outcomes (efficacy, toxicity) in a cohort of patients with mCRPC in Spain. MATERIALS AND METHODS: Multicenter, retrospective study of patients with mCRPC included in a database of the Urological Tumour Working Group (URONCOR) of the Spanish Society of Radiation Oncology (SEOR). Metastatic CRPC was defined according to the prostate cancer working group 3 (PCWG3) criteria. The Kaplan-Meier technique was used to evaluate OS and the Common Terminology Criteria for Adverse Events (CTCAE, v.4.0) were used to assess toxicity. Univariate and multivariate Cox regression analyses were performed to identify the factors significantly associated with OS. RESULTS: A total of 314 patients from 17 hospitals in Spain diagnosed with mCRPC between June 2010 and September 2017 were included in this study. Mean age at diagnosis was 68 years (range 45-89). At a median follow-up of 35 months, OS at 1, 3, and 5 years were 92%, 38%, and 28%, respectively. Grades 1-2 and grade 3 toxicity rates were, respectively, 68% and 19%. No grade 4 toxicities were observed. On the multivariate analysis, the following factors were significantly associated with OS: age (hazard ratio [HR] 0.42, p = 0.010), PSA value at diagnosis of mCRPC (HR 0.55, p = 0.008), and Gleason score (HR 0.61, p = 0.009). CONCLUSIONS: Age, Gleason score, and PSA at diagnosis of mCRPC are independently associated with overall survival in patients with mCRPC. The efficacy and toxicity outcomes in this patient cohort treated in radiation oncology departments in Spain are consistent with previous reports.

ABSTRACT

INTRODUCTION: The clinical course in patients with prostate cancer (PCa) after biochemical failure (BF) has received limited attention. This study analyzes survival time from recurrence, patterns of progression, and the efficacy of salvage therapies in patients treated with radical or postoperative radiotherapy (RT). METHODS: This is a multicenter retrospective comparative study of 1135 patients diagnosed with BF and treated with either radical (882) or postoperative (253) RT. Data correspond to the RECAP database. Clinical, tumor, and therapeutic characteristics were collected. Descriptive statistics, survival estimates, and comparisons of survival rates were calculated. RESULTS: Time to BF from initial treatment (RT or surgery) was higher in irradiated patients (51 vs 37 months). At a median follow-up of 102 months (14-254), the 8-year cause-specific survival (CSS) was 80.5%, without significant differences between the radical (80.1%) and postoperative (83.4%) RT groups. The 8-year metastasis-free survival rate was 57%. 173 patients (15%) died of PCa and 29 (2.5%) of a second cancer. No salvage therapy was given in 15% of pts. Only 5.5% of pts who underwent radical RT had local salvage treatment and 71% received androgen deprivation (AD) ± chemotherapy. The worst outcomes were in patients who developed metastases after BF (302 pts; 26.5%) and in cases with a Gleason > 7. CONCLUSIONS: In PCa treated with radiotherapy, median survival after BF is relatively long. In this sample, no differences in survival rates at 8-years have been found, regardless of the time of radiotherapy administered. AD was the most common treatment after BF. Metastases and high Gleason score are adverse variables. To our knowledge, this is the first study to compare outcomes after BF among patients treated with primary RT vs. those treated with postoperative RT and to evaluate recurrence patterns, treatments administered, and causes of death. The results allow avoiding overtreatment, improving quality of life, without negatively affecting survival.

ABSTRACT

BACKGROUND: The knowledge in the field of castration-resistant prostate cancer (CRPC) is developing rapidly, with emerging new therapies and advances in imaging. Nonetheless, in multiple areas there is still a lack of or very limited evidence, and clear guidance from clinicians regarding optimal strategy is required. METHODS: A modified Delphi method, with 116 relevant questions divided into 7 different CRPC management topics, was used to develop a consensus statement by the URONCOR group. RESULTS: A strong consensus or unanimity was reached on 93% of the proposed questions. The seven topics addressed were: CRPC definition, symptomatic patients, diagnosis of metastasis, CRPC progression, M0 management, M1 management and sequencing therapy, and treatment monitoring. CONCLUSIONS: The recommendations based on the radiation oncology experts' opinions are intended to provide cancer specialists with expert guidance and to standardise CRPC patient management in Spain, facilitating decision-making in different clinically relevant issues regarding CRPC patients.

ABSTRACT

PURPOSE: To retrospectively assess outcomes and to identify prognostic factors in patients diagnosed with intermediate-risk (IR) prostate cancer (PCa) treated with primary external beam radiotherapy (EBRT). MATERIALS AND METHODS: Data were obtained from the multi-institutional Spanish RECAP database, a population-based prostate cancer registry in Spain. All IR patients (NCCN criteria) who underwent primary EBRT were included. The following variables were assessed: age; prostate-specific antigen (PSA); Gleason score; clinical T stage; percentage of positive biopsy cores (PPBC); androgen deprivation therapy (ADT); and radiotherapy dose. The patients were stratified into one of three risk subcategories: (1) favourable IR (FIR; GS 6, ≤ T2b or GS 3 + 4, ≤ T1c), (2) marginal IR (MIR; GS 3 + 4, T2a-b), and (3) unfavourable IR (UIR; GS 4 + 3 or T2c). Biochemical relapse-free survival (BRFS), disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) were assessed. RESULTS: A total of 1754 patients from the RECAP database were included and stratified by risk group: FIR, n = 781 (44.5%); MIR, n = 252 (14.4%); and UIR, n = 721 (41.1%). Mean age was 71 years (range 47-86). Mean PSA was 10.4 ng/ml (range 6-20). The median radiotherapy dose was 74 Gy, with mean doses of 72.5 Gy (FIR), 73.4 Gy (MIR), and 72.8 Gy (UIR). Most patients (88%) received ADT for a median of 7.1 months. By risk group (FIR, MIR, UIR), ADT rates were, respectively, 88.9, 86.5, and 86.9%. Only patients with ≥ 24 months of follow-up post-EBRT were included in the survival analysis (n = 1294). At a median follow-up of 52 months (range 24-173), respective 5- and 10-year outcomes were: OS 93.6% and 79%; BRFS 88.9% and 71.4%; DFS 96.1% and 89%; CSS 98.9% and 94.6%. Complication rates (≥ grade 3) were: acute genitourinary (GU) 2%; late GU 1%; acute gastrointestinal (GI) 2%; late GI 1%. There was no significant association between risk group and BRFS or OS. However, patients with favourable-risk disease had significantly better 5- and 10-year DFS than patients with UIR: 98.7% vs. 92.4% and 92% vs. 85.8% (p = 0.0005). CSS was significantly higher (p = 0.0057) in the FIR group at 5 (99.7% vs. 97.3%) and 10 years (96.1% vs. 93.4%). On the multivariate analyses, the following were significant predictors of survival: ADT (BRFS and DFS); dose ≥ 74 Gy (BRFS); age (OS). CONCLUSIONS: This is the first nationwide study in Spain to report long-term outcomes of patients with intermediate-risk PCa treated with EBRT. Survival outcomes were good, with a low incidence of both acute and late toxicity. Patients with unfavourable risk characteristics had significantly lower 5- and 10-year disease-free survival rates. ADT and radiotherapy dose ≥ 74 Gy were both significant predictors of treatment outcomes.

ABSTRACT

Purpose: To investigate patterns of practice among Spanish radiation oncologists in the use of multiparametric magnetic resonance imaging (mpMRI) for the treatment of prostate cancer (PCa). We evaluated (1) access to mpMRI, (2) current clinical practices, and (3) physician expectations of mpMRI. Methods: Cross-sectional survey of 118 radiation oncologists at 75 Radiation Oncology (RO) departments in Spain. Results: A total of 55 radiation oncologists from 52 RO departments (52/75; 69%) completed the survey. Prostate mpMRI is performed at 94.5% of the centres that provided data. The most common indications for mpMRI in routine clinical practice were: (1) detection/localization of the tumour prior to second biopsy (82.7%), (2) cancer staging (80.8%), and (3) detection of recurrence after definitive treatment (80.8%). Most respondents (72.7%) reported modifying the primary radiotherapy treatment when mpMRI findings indicate a more advanced T stage with a resultant change in the risk group. Most respondents (90.5%) treat macroscopic local recurrence after prostatectomy with high doses, ranging from 71 to 83 Gy; in 37.7% of cases, the full dose is delivered to the entire prostate bed. In pelvic nodal recurrence, more than half (59.3%) of the respondents reported performing elective pelvic radiotherapy, including the prostate bed, with a boost to the involved nodes. Conclusions: This survey shows that prostate mpMRI is routinely used by radiation oncologists in Spain in a wide range of clinical scenarios. The findings reported here underscore the need to standardize treatment protocols for definitive and salvage radiotherapy in patients evaluated with mpMRI

ABSTRACT

La radioterapia es un tratamiento curativo indicado en pacientes con cáncer de próstata (CaP) primario y en aquellos con recurrencia bioquímica tras prostatectomía radical (PR). Además, recientemente, ha habido un aumento en el uso de técnicas de alta precisión como la radioterapia estereotáctica fraccionada corporal para tratar un número limitado de metástasis en pacientes con CaP oligometastásico. Las pruebas de imagen convencional (ecografía transrectal, tomografía computarizada [TC], resonancia magnética morfológica y gammagrafía ósea) tienen un papel menor en estos escenarios, debido a su bajo rendimiento diagnóstico. Recientemente, se ha desarrollado el radiotrazador 68Ga-PSMA, para la tomografía por emisión de positrones (PET), que es un ligando del antígeno de membrana específico de próstata (PSMA), una proteína transmembrana sobrexpresada en las células del CaP. Sus resultados son prometedores, con tasas de detección de lesiones tumorales mayores que la TC y mayor que la mejor técnica disponible actualmente, la PET con colina. Su superioridad es más evidente en pacientes con valores bajos de PSA (< 1 ng/ml). Esta mejora en el rendimiento diagnóstico representa un potencial impacto en el manejo terapéutico, especialmente en radioterapia. A pesar de que la prueba ya está disponible en la práctica clínica diaria de otros países europeos, en España su uso es muy limitado. En esta revisión, analizamos los principales estudios que investigan la utilidad de la PET/TC con 68Ga-PSMA en pacientes con CaP y su potencial impacto en los tratamientos de radioterapia. Además, comparamos la PET/TC con PSMA, con la resonancia magnética multiparamétrica y la PET/TC con colina, en los distintos escenarios clínicos


Radiotherapy is a treatment with curative intent, both in patients with primary diagnosis of prostate cancer (PCa) and in patients presenting with biochemical recurrence after radical prostatectomy (RP). Moreover, the use of stereotactic body radiotherapy as a metastasis directed therapy in patients with oligometastatic PCa has significantly increased in the recent years. Conventional imaging techniques, including transrectal ultrasound, computed tomography (CT), morphologic magnetic resonance and bone scintigraphy have traditionally played a minor role in all those clinical scenarios due to its low diagnostic accuracy. The recent development of the positron emission tomography (PET) radiotracer 68Ga-PSMA binding to the prostate specific membrane antigen (PSMA), a transmembrane glycoprotein overexpressed in PCa cells, has shown promising results. Detection rates for PCa lesions are higher than CT and higher than the best technique available, the PET/CT with choline. Its superiority has been demonstrated even at very low PSA levels (<1 ng/ml). This increase in diagnostic accuracy represents a potential impact on patient management, especially in radiotherapy. Even if this imaging technique is already available for routine clinical practice in some European countries, in Spain, unfortunately, there is very limited access. In this review, we analyze the main studies that investigate the usefulness of 68Ga-PSMA PET/CT in patients with PCa and its potential impact on radiotherapy treatments. In addition, we compared the 68Ga-PSMA PET/CT, with the multiparametric magnetic resonance imaging and the PET/CT with choline, in the different clinical scenarios

ABSTRACT

Purpose. Prostate cancer (PCa) is the most prevalent malignancy in men and the second cause of mortality in industrialized countries. Methods. Based on Spanish Register of PCa, the incidence of high-risk PCa is 29%, approximately. In spite of the evidence-based beneficial effect of radiotherapy and androgen deprivation therapy in high-risk PCa, these patients (pts) are still a therapeutic challenge for all specialists involved, in part due to the absence of comparative studies to establish which of the present disposable treatments offer better results. Results. Nowadays, high-risk PCa definition is not well consensual through the published oncology guides. Clinical stage, tumour grade, and number of risk factors are relevant to be considered on PCa prognosis. However, these factors are susceptible to change depending on when surgical or radiation therapy is considered to be the treatment of choice. Other factors, such as reference pathologist, different diagnosis biopsy schedules, surgical or radiotherapy techniques, adjuvant treatments, biochemical failures, and follow-up, make it difficult to compare the results between different therapeutic options. Conclusions. This article reviews important issues concerning high-risk PCa. URONCOR, GUO, and SOGUG on behalf of the Spanish Groups of Uro-Oncology Societies have reached a consensus addressing a practical recommendation on definition, diagnosis, and management of high-risk PCa (AU)

ABSTRACT

Purpose. We compared biochemical control and quality of life with intermittent (6 months) versus continuous (36 months) androgen deprivation therapy (ADT) in a non-inferiority randomized phase 3 trial in patients with biochemical failure (BF) after external beam radical radiotherapy (EBRT). Materials and methods. Patients were stratified according to the Gleason score (GS) and were classified as low risk with a GS < 6 and 7 (3 + 4) and high risk with a GS of 7 (4 + 3) and >7. Patients were followed with PSA determinations and quality-of-life assessments (QLQ C-30 and QLQ PR-25) every 6 months for a period of 3 years. BF after radiation was defined as a PSA level of nadir +2 ng/ml. Disease progression (DP) after ADT was defined as PSA ≥4 ng/ml (BF) and/or metastases. Results. Seventy-seven patients were included in this multicenter phase 3 trial from 2005 to 2009. Thirty-eight and 39 patients were included in the intermittent and continuous groups, respectively. The median follow-up for both groups was 48 months (40-68). DP after ADT in the intermittent group was seen in three patients (distant metastases in one patient) versus 0 in the continuous group. The QLQ-C30 and QLQ PR-25 scores did not show any statistically difference between the two ADT groups. Conclusions. No significant differences were seen in DP and QLQ between intermittent (6 months) and continuous (36 months) ADT in patients with BF after EBRT (AU)

ABSTRACT

Purpose: To report treatment outcomes in a cohort of extreme-risk prostate cancer patients and identify a subgroup of patients with worse prognosis. Materials and methods: Extreme-risk prostate cancer patients were defined as patients with at least one extremerisk factor: stage cT3b-cT4, Gleason score 9-10 or PSA[50 ng/ml; or patients with 2 or more high-risk factors: stage cT2c-cT3a, Gleason 8 and PSA[20 ng/ml. Overall survival (OS), cause-specific survival (CSS), clinical- free survival (CFS), and biochemical non-evidence of disease (bNED) survival are the four outcomes of interest in a population of 1341 patients. Results: With a median follow-up of 71.5 months, 5- and 10-year bNED survival, CFS, CSS and OS for the entire cohort were 77.1 % and 57.0, 89.2 and 78.9 %, 97.4 and 93.6 %, and 92.0 and 71.3 %, respectively. On multivariateanalysis, PSA and clinical stage were associated with bNED survival. PSA and Gleason score predicted for CFS, whereas only Gleason score predicted for OS. When a simplified model was performed using the "number of risk factors" variable, this model provided the best distinction between patients with C2 extreme-risk factors and patients with 2 high-risk factors, showing a hazard ratio (HR) of 1.737 (p = 0.0003) for bNED survival, HR 1.743 (p = 0.0448) for OS and an HR of 3.963 (p = 0.0039) for the CSS endpoint. Conclusions: Patients presenting at diagnosis with two extreme-risk criteria have almost fourfold higher risk for prostate cancer mortality. Such patients should be considered for more aggressive multimodal treatments (AU)

ABSTRACT

PURPOSE: To evaluate the cosmetic outcome of breast conservative therapy and to examine the degree of agreement between the patients' and oncologists' ratings. We also analyze the influence of several factors on cosmesis. METHODS AND MATERIALS: We retrospectively evaluated 145 patients with primary breast cancer treated by local excision and radiotherapy between January 2000 and May 2001. Cosmetic outcome was evaluated by doctors and patients and was scored as excellent, good, fair or poor. RESULTS: 73% of patients rated cosmesis as excellent or good while the percentage was 71% when rated by radiation oncologists. The degree of cosmesis concordance evaluated by oncologists and patients was low (kappa = 0.3). In our study the variables which significantly influence on the cosmetic outcome were concomitant adjuvant chemotherapy (p = 0.04) and radiation therapy boost, either by electron beam or brachytherapy (p = 0.013). CONCLUSION: The cosmetic outcome of breast conserving therapy was good. There was a similar rating by the patient and radiation oncologist, but the level of concordance between patients and doctors was low. Factors that significantly influence the cosmesis appear to be concomitant adjuvant chemotherapy and radiation therapy boost.

ABSTRACT

La radioterapia externa y la braquiterapia de alta tasa de dosis (hdr-bqt) es un tratamiento efectivo en el carcinoma de próstata. La vía endovenosa y la colocación de un catéter epidural son técnicas frecuentes de analgesia postbraquiterapia. Estos métodos invasivos producen un enorme discomfort en el paciente, con un incremento de la morbilidad y disminución de la calidad del procedimiento. Un avance significativo en el manejo del dolor es poder administrar opioides por vías no invasivas, entre otras, la transdérmica. El opioide idóneo debe ser efectivo, seguro, cómodo, de vida media prolongada, y tener una relación coste-beneficio aceptable. El sistema terapéutico fentanilo-TTS (Durogesic®), es el fármaco que mejor se adapta a estos criterios. Se presentan los primeros resultados descritos en la literatura que evalúan la efectividad y seguridad del sistema terapéutico fentanilo-TTS administrado preoperatoriamente para obtener una analgesia postoperatoria, como parte de un programa analgésico no invasivo, en los pacientes con carcinoma de próstata, sometidos a hdr-bqt (AU)

ABSTRACT

Propósito: Se analizan los resultados de un estudio llevado a cabo en pacientes remitidos a varios Servicios de Oncología Radioterápica para tratamiento del dolor causado por procesos oncológicos. Se estudian las características del dolor, tratamiento analgésico previo, su modificación y la efectividad y seguridad de Fentanilo TTS cuando fue pautado. Material y métodos: Se analizan los datos recogidos en un periodo de 1 mes de 274 pacientes. Los tumores más prevalentes en el estudio fueron: Cáncer de pulmón en el 25 por ciento, de mama en el 16.8 por ciento y de próstata en el 14 por ciento. El 50 por ciento de los pacientes presentaban dolor somático sin componente neuropático, el 28 por ciento dolor somático con componente neuropático y en el 19 por ciento como parte de una compresión medular. Resultados: En el 8 por ciento de los pacientes se registraron intensidades de dolor menores a 3 en la escala analógica visual (EVA), entre 3 y 6 en el 42 por ciento y mayores de 6 en el 51 por ciento. En 155 pacientes, el 56 por ciento del total, se modificó el tratamiento analgésico, indicando Fentanilo-TTS. Después del tratamiento RT-Fentanilo se produjo una reducción media de la EVA de cuatro puntos. Los fenómenos secundarios, náuseas, vómitos, estreñimiento y somnolencia, se identificaron en un 30 por ciento de los pacientes y fueron considerados como moderados en la totalidad de los casos, salvo constipación que se valoró como grave en el 7 por ciento de los pacientes. Conclusiones: Los pacientes que llegan a las consultas de Oncología Radioterápica presentan dolor deficientemente controlado y lo hacen con intensidades de dolor consideradas como severas en el 50 por ciento de los casos. El tratamiento Radioterapia (RT) - Fentanilo fue muy efectivo reduciendo cuatro puntos la EVA quedando como controlado el dolor en la mayoría de los pacientes. Los efectos secundarios fueron moderados (AU)

ABSTRACT

Objetivo: Analizar la correlación existente entre el Ecocardiograma (Eco) fetal y el diagnóstico cardiológico de recién nacido (RN). Investigar la mortalidad de los cardiópatas diagnosticados in útero incluyendo abortos y fallecidos in útero en un período de 2 años. Material y Método: Se realizó un estudio prospectivo entre enero de 1999 y diciembre del 200 en el cual se evalúa mediante un Protocolo de Seguimiento de Ecocardiografía Fetal a aquellas pacientes (p) que cursaban un embarazo de 24 semanas o más y que fueron enviadas a realizar Eco fetal en el Hospital Luis Calvo Mackenna. Clínica las Condes o Salvecor. Resultados: Se efectuaron un total de 241 Eco fetales en 156 pacientes. El seguimiento posterior vario entre 5 y 19 meses desde el momento del nacimiento. Del total de 156 p examinados se encontraron 76 p cardiópatas (48 por ciento), de éstos presentaron arritmias 21 p, cardiopatías estructurales 55 p. Falta de correlación :A) no se diagnosticó: 1 p con estenosis pulmonar leve, 1 dextrocardía, 2 coartación aórtica, 1 tronco en polihidroamnios, 1 interrupción cayado aórtico en ventrículo único. B) se confundió aorta con pulmonar con 2 ventrículo únicos con atresia aórtica, una DTGA con LTGA en un paciente portador de ventrículo único, se confunde una displasia tricúspidea con Ebstein y una hipoplasia de ventrículo derecho (VD) con Ebstein C) se diagnosticaron; 1 comunicaciones interventriculares que no se encontraron en el momento del nacimiento. D) se desconocen: por no contar con el resultado del Eco de RN la evolución de 12 RN de los cuales 8 eran patológicos, de estos 3 fallecieron en el período neonatal. Estado actual: de los 156 p estudiados 91 (58 por ciento) no presentaban cardiopatías al momento de evaluar el estudio. Del total de pacientes (156 p), los fallecidos, incluyendo mortinatos 18 (11 por ciento). Los fallecidos, del total de cardiópatas (76p) es el 23 por ciento. Análisis de fallecidos: 2 mortinatos, 11 p fueron considerados fuera del alcance quirúrgico, 2 p con diagnóstico de doble salida de VD, 2 p fallecidos en el post operatorio, 1 p después de operación de colón. Conclusión: La correlación encontrada es aceptable (91,6 por ciento). La mortalidad hallada es más baja que la encontrada en publicaciones extranjeras, más aún si se considera que incluimos mortinatos, en nuestro estudio no encontramos abortos
