Objetivos
Evaluar los resultados de la prostatectomía radical asistida por robot (PRAR), y compararlos con los de la cirugía abierta (PRA) y laparoscópica (PRL). El interés no solo radica en los resultados oncológicos y funcionales de la serie, sino en la evaluación de la calidad de vida (QoL), la recuperación postoperatoria y la satisfacción personal de los pacientes con la intervención (PR), fundamentalmente.
Métodos
Se realizaron 685 PR en nuestro centro entre 2011-2018 (17,8% PRA, 22,2% PRL y 60% PRAR). Los pacientes fueron evaluados prospectivamente mediante seguimiento hasta abril de 2020, y con la realización un cuestionario múltiple a los 12 meses post-PR, que incluía ICIQ-SF, SHIM, IPSS, IQL y preguntas sobre el dolor, la recuperación postoperatoria y la satisfacción del paciente (SP). También se recogieron datos basales y postoperatorios relacionados con el paciente y el tratamiento, y se realizaron regresiones logísticas binomiales para las comparaciones 1 vs. 1 (PRA vs. PRAR y PRL vs. PRAR).
Resultados
Los pacientes tratados con PRAR tienen en general menos comorbilidades, menos agresividad tumoral, un requerimiento de mayor tiempo operatorio y un número mayor de márgenes quirúrgicos positivos que los pacientes tratados con PRA y PRL. Sin embargo, la PRAR supera a la PRA en: días de estancia hospitalaria (OR: 0,86; IC 95%: 0,80-0,94), disminución de hemoglobina (OR: 0,38; IC 95%: 0,30-0,47), tasas de transfusión (OR: 0,18; IC 95%: 0,09-0,34), complicaciones tempranas (p = 0,001), IQL (OR: 0,82; IC 95%: 0,69-0,98), función eréctil (OR: 0,41; IC 95%: 0,21-0,79), manejo del dolor (OR: 0,82; IC 95%: 0,75-0,89), recuperación postoperatoria (p < 0,001) y elección de un abordaje diferente (OR: 5,55; IC 95%: 3,14-9,80). La PRAR es superior a la PRL en: continencia urinaria (OR: 0,55; IC 95%: 0,37-0,82), IPSS (OR: 0,96; IC 95%: 0,93-0,98), IQL (OR: 0,76; IC 95%: 0,66-0,88), función eréctil (OR: 0,52; IC 95%: 0,29-0,93), recuperación posquirúrgica (p = 0,02 y 0,004), PS (p = 0,005; 0,002; y 0,03) y elección de un abordaje diferente (OR: 7,79; IC 95%: 4,63-13,13).
Conclusiones
Los hallazgos de nuestro estudio respaldan la efectividad de la PRAR sobre la PRL y/o la PRA de manera global, tanto en factores funcionales, como en la recuperación postoperatoria, la QoL y la PS. Los resultados oncológicos aún deben ser mejorados.

Background: Myeloid-derived suppressor cells (MDSCs) are relevant in prostate cancer microenvironment collaborating in tumor development. The main tumor marker used in this disease, prostate-specific antigen (PSA), does not provide information related to this tumor microenvironment. Cancer cells secrete exosomes carrying bioactive molecules contributing to MDSCs recruitment and induction. The aim of this study was to characterize the perioperative changes of exosomal cytokines relevant in MDSCs recruitment induced by prostatectomy in prostate cancer patients.
Methods: Blood was drawn from 26 early-stage prostate cancer patients before and after radical prostatectomy and from 16 healthy volunteers. Serum exosomes were separated by precipitation. Cytokines related with MDSC cell recruitment and activation CCL2, CXCL2, CXCL5, CXCL8, CXCL12, MIF, S100A9 and TGF-ß were measured in serum and serum-derived exosomes using immunometric assays.
Results: All cytokines were detected both in serum and exosomes, except for CXCL12, which was detected only in serum. Exosomes were enriched specially in MIF, TGF-ß and CXCL2. Presurgical MIF levels in exosomes correlated negatively with serum PSA. Also, presurgical TGF-ß decreased both in serum and exosomes as Gleason score rises. Patient¿ presurgical exosomes had increased CCL2, CXCL5 and TGF-ß levels than exosomes from healthy controls. These differences were not observed when cytokines were analyzed in serum, except for TGF-ß. Cytokine ...

Aims To identify the definition for urinary continence (UC) after radical prostatectomy (RP) which reflects best patients' perception of quality of life (QoL). Methods Continence was prospectively assessed in 634 patients, 12 months after RP using the International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) and the number of pads employed in a 24-hour period (pad usage). We used the one-way ANOVA technique with posthoc pairwise comparisons according to Scheffe's method (homogeneous subsets) for assessing the degree of QoL deficit related to urinary incontinence (UI). Results The continence prevalence is 64.4%, 74.1%, 88.3%, and 35.8% using "0 pads," "1 safety pad," "1 pad," and "ICIQ score 0" definitions, respectively. Pad usage is moderately strongly associated with ICIQ 1, 2, and 3 (rho = 0.744, 0.677, and 0.711, respectively; p < 0.001). Concordance between classical UC definitions is acceptable between "0 pads-ICIQ score 0" (K = 0.466), but poor for "1 safety pad" and "1 pad" (K = 0.326 and 0.137, respectively). Patients with "0 pad usage" have better QoL related to urine leakage than patients with "1 safety pad" or "1 pad" (1.41 vs. 2.44 and 3.11, respectively; p < 0.05). There were no significant differences found regarding QoL between patients with ICIQ score 0 and ICIQ score 2 (1.01 vs. 1.63; p = 0.63). Conclusions Pad usage and the ICIQ-SF's answers provide useful information. We propose a combined definition (0 pads and ICIQ score <= 2) as it is the definition with the least impact on daily QoL.
