Abstract

BACKGROUND

The role of adjuvant chemotherapy in resected stage II colon cancer remains controversial. Treatment recommendations rely largely on the presence of certain high-risk features for recurrence.

OBJECTIVE

We sought to define patient and clinicopathologic differences between early-onset and late-onset colorectal cancer and determine whether these differences impact treatment. We hypothesized that high-risk features in stage II colorectal cancer differed between age groups and would most strongly influence administration of adjuvant chemotherapy.

DESIGN

This was a retrospective cohort study.

SETTING

The study was conducted at a Commission on Cancer designated hospital as well as the National Cancer Institute Intramural Research Program.

PATIENTS

Patients with resected stage II colon cancer were identified in the National Cancer Database, and clinicopathologic characteristics were recorded. Patients were stratified into young (≤45), middle-aged (50-75), and older (>75) age groups.

MAIN OUTCOME MEASURES

Incidence of high-risk clinicopathologic features and receipt of adjuvant chemotherapy were measured.

RESULTS

A total of 14,966 patients met inclusion criteria. Young patients were found to have had at least one high-risk feature ( n = 489, 44%) slightly more often than both middle-aged ( n = 3734, 40%) and older patients ( n = 1890, 42%). A total of 332 (7%) older patients received adjuvant chemotherapy compared to 627 (56%) young patients and 2854 (30%) middle-aged patients. Age group was independently associated with receipt of adjuvant chemotherapy when controlling for relevant clinicopathologic factors.

LIMITATIONS

This was a retrospective study without granular detail on treatment decisions.

CONCLUSIONS

Young patients are frequently prescribed adjuvant chemotherapy for both high- and low-risk tumors despite questionable benefit in the latter. Older patients rarely receive adjuvant therapy. Both medical and surgical oncologists should be aware of disparities in cancer treatment and remain conscientious about making treatment decisions solely based on age.

Un total de 332 (7%) de los pacientes mayores recibieron quimioterapia adyuvante en comparación con 627 (56%) de los pacientes jóvenes y 2854 (30%) de los pacientes de mediana edad.

Los pacientes de edad avanzada rara vez reciben terapia adyuvante. Tanto los oncólogos clínicos como los quirúrgicos deben ser conscientes de las disparidades en el tratamiento del cáncer y ser conscientes de tomar decisiones de tratamiento basadas únicamente en la edad.

摘要

背景

在 II 期结肠癌中,辅助化疗的作用仍存在争议。治疗建议主要依赖于是否存在某些高复发风险特征。

目的

我们旨在明确早发性和迟发性结直肠癌患者之间的患者和临床病理差异,并确定这些差异是否会影响治疗。我们假设 II 期结直肠癌的高危特征在不同年龄组之间存在差异,并将对辅助化疗的实施产生最大影响。

设计

这是一项回顾性队列研究。

地点

该研究在癌症委员会指定的医院以及国家癌症研究所院内研究计划中进行。

患者

在国家癌症数据库中确定了 II 期结肠癌患者,并记录了临床病理特征。患者被分为年轻组(≤45 岁)、中年组(50-75 岁)和老年组(>75 岁)。

主要观察指标

高危临床病理特征的发生率和接受辅助化疗的情况。

结果

共有 14966 名患者符合纳入标准。与中年组(n=3734,40%)和老年组(n=1890,42%)相比,年轻组(n=489,44%)患者发生至少一种高危特征的比例略高。332 名(7%)老年患者接受了辅助化疗,而 627 名(56%)年轻患者和 2854 名(30%)中年患者接受了辅助化疗。在校正相关临床病理因素后,年龄组与接受辅助化疗独立相关。

局限性

这是一项回顾性研究,没有关于治疗决策的详细信息。

结论

尽管在后者中辅助化疗的获益存在疑问,但年轻患者仍经常被开具高危和低危肿瘤的辅助化疗。老年患者很少接受辅助治疗。内科肿瘤学家和外科肿瘤学家都应该意识到癌症治疗中的差异,并注意仅根据年龄做出治疗决策。
