Abstract

BACKGROUND: Primary colorectal lymphoma is rare, representing 0.2% to 0.6% of all colorectal cancers. Because of its low incidence and histologic variety, no treatment guidelines exist. OBJECTIVE: The purpose was to report the experience of primary colorectal lymphoma in an institutional and a national cohort. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted with institutional data composed of 3 tertiary referral centers and national data. PATIENTS: Patients with primary colorectal lymphoma were identified within the Mayo Clinic (1990-2016) and the Surveillance, Epidemiology, and End Results database (1990-2014). MAIN OUTCOME MEASURES: Primary outcomes were overall and 5-year survival. RESULTS: For the institutional cohort (N = 82), 5-year survival was 79.9%. Five-year survival was higher for rectal (88.4%) than for colon tumors (77.2%; p = 0.004). On multivariable analysis, age <50 years was associated with higher overall survival (p = 0.04). Left-sided colon masses and aggressive histological subtypes were associated with worse survival (0.04 and 0.03). No effect of treatment modality on survival was noted. For the national cohort (N = 2942), 5-year survival was 58.4%. Five-year survival for rectal tumors was 61.0% and 57.8% for colon tumors. On multivariable analysis, factors associated with improved survival were age <70 y, (p < 0.0001), female sex (p = 0.005), right-sided masses (p = 0.02), and diagnoses after 2000 compared with 1990-1999 (p < 0.0001). Aggressive pathology (p < 0.0001) and stage III or stage IV presentation compared with stage I (p = 0.02 and p < 0.0001) were associated with worse survival. LIMITATIONS: The institutional cohort was limited by sample size to describe treatment effect on survival. A major limitation of the national cohort was the ability to describe treatment modalities other than surgery, including chemotherapy and/or no additional treatment. CONCLUSIONS: Poorer survival was noted in elderly patients and in those with aggressive pathology. An overall survival advantage was seen in women in the national cohort. Currently, optimal strategies should follow a patient-centered multidisciplinary approach. See Video Abstract at http://links.lww.com/DCR/A807. LINFOMA COLORECTAL PRIMARIO: EXPERIENCIA INSTITUCIONAL Y REVISIÓN DE UNA BASE DE DATOS NACIONAL: El linfoma colorectal primario es poco frecuente, representando del 0.2% al 0.6% de todos los cánceres colorectales. Debido a su baja incidencia y variedad histológica, no existen guías de tratamiento. OBJETIVO: El propósito fue reportar la experiencia en linfoma colorectal primario en una cohorte institucional y una nacional. DISEÑO:: Este fue un estudio de cohorte retrospectivo. ESCENARIO: El estudio se realizó con datos institucionales provenientes de 3 centros de referencia terciarios y datos nacionales. PACIENTES: Se identificaron pacientes con linfoma colorectal primario en la base de datos de la Clínica Mayo (1990-2016) y en la base de datos de vigilancia, epidemiología y resultados finales [Surveillance, Epidemiology, and End Results database (1990-2014)]. PRINCIPALES MEDIDAS DE RESULTADO: Los resultados primarios fueron la sobrevida general y a 5 años. RESULTADOS: Para la cohorte institucional (N = 82), la sobrevida a 5 años fue de 79.9%. La sobrevida a cinco años fue mayor en tumores rectales (88.4%) que en los de colon (77.2%; p = 0.004). En el análisis multivariable, la edad <50 años se asoció con una mayor sobrevida general (p = 0,04). Las masas de colon izquierdo y los subtipos histológicos agresivos se asociaron con una peor sobrevida (0.04 y 0.03). No se observó ningún efecto según la modalidad de tratamiento en la sobrevida. Para la cohorte nacional (N = 2942), la sobrevida a 5 años fue del 58.4%. La sobrevida a cinco años fue de 61.0% para los tumores rectales y 57.8% para los tumores de colon. En el análisis multivariable, los factores asociados con una mayor sobrevida fueron edad <70 años, (p <0.0001), sexo femenino (p = 0.005), masas derechas (p = 0.02) y los casos diagnósticados después del año 2000 comparados con los de 1990-1999 (p <0.0001). Histopatología agresiva (p <0.0001) y presentación en estadio III o estadio IV en comparación con estadio I (p = 0.02 y p <0.0001) se asociaron con una peor sobrevida. LIMITACIONES: La cohorte institucional estuvo limitada por el tamaño de la muestra para describir el efecto del tratamiento en la sobrevida. Una limitación mayor en la cohorte nacional fue la habilidad para describir modalidades de tratamiento distintas a la cirugía, incluyendo quimioterapia y/o ningún tratamiento adicional. CONCLUSIONES: Una menor sobrevida fue documentada en pacientes de edad avanzada y en aquellos con histopatología agresiva. Se observó ventaja en cuanto a sobrevida general en las mujeres de la cohorte nacional. Actualmente, las estrategias óptimas deben de seguir un abordaje multidisciplinario centrado en cada paciente.

摘要

原发性结直肠淋巴瘤罕见,占所有结直肠癌的 0.2%至 0.6%。由于其发病率低且组织学多样,目前尚无治疗指南。

目的:报告机构和国家队列中原发性结直肠淋巴瘤的经验。

设计:这是一项回顾性队列研究。

地点:研究使用了由 3 个三级转诊中心组成的机构数据和国家数据。

患者:在梅奥诊所(1990-2016 年)和监测、流行病学和最终结果数据库(1990-2014 年)中确定了原发性结直肠淋巴瘤患者。

主要观察指标:主要结局为总生存率和 5 年生存率。

结果:对于机构队列(N=82),5 年生存率为 79.9%。直肠肿瘤的 5 年生存率(88.4%)高于结肠肿瘤(77.2%;p=0.004)。多变量分析显示,年龄<50 岁与总体生存率更高相关(p=0.04)。左半结肠肿块和侵袭性组织学亚型与较差的生存率相关(0.04 和 0.03)。治疗方式对生存率无影响。对于国家队列(N=2942),5 年生存率为 58.4%。直肠肿瘤的 5 年生存率为 61.0%,结肠肿瘤为 57.8%。多变量分析显示,与生存率提高相关的因素包括年龄<70 岁(p<0.0001)、女性(p=0.005)、右侧肿块(p=0.02)以及 2000 年后诊断(与 1990-1999 年相比,p<0.0001)。侵袭性病理(p<0.0001)和 III 或 IV 期与 I 期相比(p=0.02 和 p<0.0001)与较差的生存率相关。

局限性:机构队列的样本量有限,无法描述治疗对生存率的影响。国家队列的一个主要局限性是能够描述手术以外的治疗方式,包括化疗和/或无额外治疗。

结论:年龄较大的患者和侵袭性病理患者的生存率较差。在国家队列中,女性的总体生存率优势明显。目前,最佳策略应遵循以患者为中心的多学科方法。
