BACKGROUND: “Days at home up to 30 days” is a novel patient-centered outcome metric that measures the number of days patients spend at home 30 days after surgery. It encompasses inpatient stay from index admission, interhospital transfers and step-downs, and readmissions across different hospitals. OBJECTIVE: Comparison of days at home up to 30 days and established outcome metrics after robotic versus 3-dimensional laparoscopic colorectal surgery. DESIGN: Prospective cohort study of consecutive patients. SETTING: Townsville University Hospital and Mater Private Hospital, Townsville, Queensland, Australia. PATIENTS: Adult patients undergoing robotic and 3-dimensional laparoscopic colorectal surgery. MAIN OUTCOME MEASURES: Days at home up to 30 days, 30-day readmission rate, index admission length, and 30-day postoperative complication rates. RESULTS: Of 82 patients, 32 (39%) underwent robotic and 50 (61%) underwent 3-dimensional laparoscopic colorectal surgery. Robotic ultralow and low anterior resection, as well as abdominoperineal resection, resulted in significantly more days at home (23 vs 15 days at home, p = 0.05) and a shorter length of index admission (7 vs 15 days in hospital, p = 0.0003). However, there was no significant difference in major postoperative complications and 30-day readmission rate. No significant differences were found between robotic and 3-dimensional laparoscopic right hemicolectomy or high anterior resection. LIMITATIONS: Unrandomized study. Patient selection for robotic and 3-dimensional laparoscopic surgery was at the surgeons’ discretion. CONCLUSIONS: Patients undergoing robotic ultralow and low anterior resection, as well as abdominoperineal resection, spent more days at home 30 days after index surgery due to a reduction in the length of the index hospital admission. Days at home up to 30 days may enhance the informed consent and complement traditional end points in future clinical trials. See Abstract Video. DÍAS EN CASA HASTA 30 DÍAS DESPUÉS DE LA CIRUGÍA COLORRECTAL ROBÓTICA FRENTE A LA LAPAROSCÓPICA ANTECEDENTES: «Días en el hogar hasta 30 días» es una nueva métrica de resultados centrada en el paciente que mide el número de días que los pacientes pasan en su hogar 30 días después de la cirugía. Abarca la estancia hospitalaria desde el ingreso inicial, los traslados entre hospitales y los traslados a unidades de cuidados intermedios, así como los reingresos en diferentes hospitales. OBJETIVO: Comparación de los días en casa hasta 30 días y las métricas de resultados establecidas tras la cirugía robótica frente a la cirugía laparoscópica tridimensional. DISEÑO: Estudio prospectivo de cohortes de pacientes consecutivos. ENTORNO: Hospital Universitario de Townsville y Hospital Privado Mater, Townsville, Queensland, Australia. PACIENTES: Pacientes adultos sometidos a cirugía colorrectal robótica y laparoscópica tridimensional. PRINCIPALES MEDIDAS DE RESULTADO: Días en el domicilio hasta 30 días, tasa de reingresos a los 30 días, duración de la admisión inicial y tasas de complicaciones postoperatorias a los 30 días. RESULTADOS: De los 82 pacientes, 32 (39 %) se sometieron a cirugía robótica y 50 (61 %) a cirugía colorrectal laparoscópica tridimensional. La resección anterior robótica ultrabaja y baja, así como la resección abdominoperineal, dieron lugar a un número significativamente mayor de días en el domicilio (23 frente a 15 días en el domicilio, p = 0,05) y a una menor duración de la hospitalización inicial (7 frente a 15 días en el hospital, p = 0,0003). Sin embargo, no se observaron diferencias significativas en las complicaciones postoperatorias graves ni en la tasa de reingresos a los 30 días. No se encontraron diferencias significativas entre la hemicolectomía derecha robótica y laparoscópica tridimensional, así como la resección anterior alta. LIMITACIONES: Estudio no aleatorizado. La selección de los pacientes para la cirugía robótica y laparoscópica tridimensional se realizó a criterio de los cirujanos. CONCLUSIÓN: Los pacientes sometidos a resección anterior robótica ultrabaja y baja, así como a resección abdominoperineal, pasaron más días en casa 30 días después de la cirugía índice debido a la reducción de la duración de la hospitalización índice. Los días en casa hasta 30 días pueden mejorar el consentimiento informado y complementar los criterios de valoración tradicionales en futuros ensayos clínicos. (AI-generated translation)

Abstract Prostate cancer is the second most common malignancy among men worldwide. Genome-wide association studies have identified 100 risk variants for prostate cancer, which can explain approximately 33% of the familial risk of the disease. We hypothesized that a comprehensive analysis of genetic variations found within the 3′ untranslated region of genes predicted to affect miRNA binding (miRSNP) can identify additional prostate cancer risk variants. We investigated the association between 2,169 miRSNPs and prostate cancer risk in a large-scale analysis of 22,301 cases and 22,320 controls of European ancestry from 23 participating studies. Twenty-two miRSNPs were associated (P < 2.3 × 10−5) with risk of prostate cancer, 10 of which were within 7 genes previously not mapped by GWAS studies. Further, using miRNA mimics and reporter gene assays, we showed that miR-3162-5p has specific affinity for the KLK3 rs1058205 miRSNP T-allele, whereas miR-370 has greater affinity for the VAMP8 rs1010 miRSNP A-allele, validating their functional role. Significance: Findings from this large association study suggest that a focus on miRSNPs, including functional evaluation, can identify candidate risk loci below currently accepted statistical levels of genome-wide significance. Studies of miRNAs and their interactions with SNPs could provide further insights into the mechanisms of prostate cancer risk. Cancer Discov; 5(4); 368–79. ©2015 AACR.
