Management of Significant Polyp and Early Colorectal Cancer Is Optimized by Implementation of a Dedicated Multidisciplinary Team Meeting: Lessons Learned From the United Kingdom National Program.

BACKGROUND: The concept of significant polyps and early colorectal cancer encompasses complex polyps not amenable to routine snare polypectomy or where malignancy cannot be excluded. The assessment and management of these lesions is contentious and increasingly important due to the significant risk of over- or undertreatment. OBJECTIVE: Following the recommendations of the Significant Polyps and Early Colorectal Cancer National Program, we implemented a dedicated multidisciplinary team meeting and analyzed the influence on patient outcomes. DESIGN: This was a retrospective study using a prospectively collected database of patients discussed at the dedicated multidisciplinary team meeting. SETTINGS: This study was conducted in a single tertiary-care center. PATIENTS: Consecutive patients with significant polyps and early colorectal cancer were identified either through the Bowel Cancer Screening Program or colonoscopy for symptomatic patients. MAIN OUTCOME MEASURES: Proportions of patients who had organ preservation, and secondary treatment and recurrence rate served as outcome measures. RESULTS: Overall, 135 patients discussed at the dedicated multidisciplinary team meeting were included, with a median age of 71 years. Median size of the lesions was 25 mm, and 39% were in the rectum. Patients were discussed either after the lesion was removed during the initial colonoscopy (n = 38), of whom 16 (42%) had unexpected cancer, or had no initial treatment with subsequent case review (n = 97). Of these 97 patients, 46 underwent endoscopic excision (26% cancer), 20 trans-anal excision (10% cancer), 23 primary surgical resection (35% cancer), and 8 had no treatment. In 104 (82%) patients, organ preservation was achieved. Secondary surgery was required in 7 of 104 (6.7%) patients after local excision due to radical treatment of high-risk T1 lesions, local recurrence, or patients' decisions. The cumulative hazard estimates for recurrence after a median follow-up of 18.5 months was less than 10% for both benign and malignant lesions. LIMITATIONS: This study was limited by its relatively small sample size and single-center setting. CONCLUSIONS: A dedicated multidisciplinary team meeting improved the management of significant polyps and early colorectal cancer, safely refining organ preservation for patients, with low recurrence rates.

La evaluación y el manejo de estas lesiones es controversial y cada vez más importante debido al riesgo significativo de ser tratadas o no.OBJETIVO:Siguiendo las recomendaciones del Programa Nacional de Pólipos Complejos y Cáncer Colorrectal Temprano, implementamos reuniónes del equipo multidisciplinario especializado y analizamos el impacto en los resultados de los pacientes.DISEÑO:Estudio retrospectivo sobre una base de datos recopilada prospectivamente de los pacientes discutidos en la reunión del equipo multidisciplinario especializado.AJUSTE:Este estudio se realizó en un centro de atención terciaria.PACIENTES:Pacientes consecutivos con pólipos complejos y cáncer colorrectal temprano identificado a través del Programa de detección de cáncer intestinal o colonoscopia para pacientes sintomáticos.PRINCIPALES MEDIDAS DE RESULTADO:Proporción de pacientes que tuvieron preservación de órganos, tratamiento secundario y tasa de recurrencia.RESULTADOS:En total, se incluyeron 135 pacientes discutidos en la reunión del equipo multidisciplinario especializado dedicada, con una media de edad de 71 años. El tamaño medio de las lesiones fue de 25 mm y el 39% estaban en el recto. Se discutio de los pacientes después de que se resecara la lesión durante la colonoscopia inicial [n = 38, de los cuales 16 (42%) tenían un cáncer imprevisto] o no recibieron tratamiento de inicio, con revisión posterior del caso (n = 97). De estos, 46/97 fueron sometidos a resección endoscópica (26% cáncer), 20/97 resección transanal (10% cáncer), 23/97 resección quirúrgica primaria (35% cáncer) y 8/97 no recibieron tratamiento. En 104 (82%) pacientes, se logró la preservación de órgano. Cirugía secundaria fue requeria en 7/104 (6,7%) pacientes después de la resección local debido a tratamiento radical de lesiones T1 de alto riesgo, recidiva local o decisión del paciente. Las estimaciones de riesgo acumulativo de recurrencia después de una media de seguimiento de 18,5 meses fue inferior al 10% tanto para las lesiones benignas como para las malignas.LIMITACIONES:Tamaño de muestra relativamente pequeño y entorno de un solo centro.CONCLUSIONES:La Reunion del equipo multidisciplinario especializado mejoró el manejo de los pólipos complejos y cáncer colorrectal temprano, refinando de manera segura la preservación de órganos para los pacientes, con bajas tasas de recurrencia.

Effect of Pre-operative Anaemia on Post-operative Complications in Low-Resource Settings.

BACKGROUND: In high-resource settings, even mild anaemia is associated with an increased risk of post-operative complications. Whether this is true in low-resource settings is unclear. We aimed to evaluate the effect of anaemia on surgical outcomes in the Republic of Congo and Madagascar. METHOD: It is a retrospective chart review of 2064 non-pregnant patients undergoing elective surgery with Mercy Ships. Logistic regression was used to determine the association between pre-operative anaemia and pre-defined surgical complications, adjusted for age, gender, surgical specialty, and country. RESULTS: The average age of patients was 27.2 years; 56.7% were male. Sixty-two percent of patients were not anaemic, and 22.7, 13.9 and 1.4% met sex-related criteria for mild, moderate and severe anaemia, respectively. In adjusted analyses, the severe anaemia group had an 8.58 [3.65, 19.49] higher odds of experiencing any surgical complication (p < 0.001) compared to non-anaemic patients. Analysis of each complication showed a 33.13 [9.57, 110.39] higher odds of unexpected ICU admission (p < 0.001); a 7.29 [1.98, 21.45] higher odds of surgical site infection (p < 0.001); and 7.48 [1.79, 25.78] higher odds of requiring hospital readmission (p < 0.001). Evaluating other anaemia categories, only those with moderate anaemia had a higher risk of requiring ICU admission (odds ratio 2.75 [1.00, 7.04], p = 0.04) compared to those without anaemia. CONCLUSION: Our results indicate that in low-income settings, severe anaemia is associated with an increased risk of post-operative complications including unexpected ICU admission, surgical site infection and hospital readmission, whereas mild anaemia was not associated with increased post-operative complications.

High prevalence of renal dysfunction and association with risk of death amongst HIV-infected Ghanaians.

OBJECTIVES: To determine the prevalence of HIV-associated renal dysfunction (RD), identify risk factors for RD and explore the association between baseline renal function and mortality in an HIV-infected population in Ghana. METHODS: Creatinine clearance (CrCl) or estimated glomerular filtration rate (eGFR) was calculated in patients attending an HIV clinic between 2004 and 2011 using Cockcroft-Gault, MDRD and CKD-EPI formulae. Logistic regression analysis was used to identify risk factors associated with RD and Kaplan-Meier/Cox proportional regression analyses to explore associations between baseline CrCl/eGFR and subsequent mortality. RESULTS: In 3137 patients starting antiretroviral therapy (ART) the frequency (95%-CI) of RD, defined by CrCl <60 ml/min/1.73 m(2) using Cockroft-Gault formula was 38.8% (37.1-40.5%). RD prevalence in a sub-population of 238 patients, including proteinuria in the definition, was 15.3% (10.3-22.1%) in ART-treated and 43.6% (34.0-53.7%) in ART-naïve patients. RD at baseline was associated with increasing age, low CD4 counts, advanced WHO stage and female gender. Cox proportional hazard analysis identified an increased hazard of death with decreasing CrCl, HR 1.46 (1.31-1.63) for each tertile lower than CrCl of 90 ml/min/1.73 m(2). CONCLUSIONS: RD is very common in HIV-infected ART-naïve Ghanaians, and associated with increased risk of mortality. Screening and monitoring of RD is important in this setting, particularly as tenofovir use increases.
