Besides tumor characteristics, colorectal cancer (CRC) outcomes are also determined by host factors, in particular the systemic inflammatory response. The basis of this relationship with survival is not known; however, systemic inflammation may reflect comorbidity. The present study examines relationships between host factors (including age, comorbidity, deprivation, and systemic inflammation) and survival in CRC.
A total of 302 patients underwent curative elective CRC resection between 1997 and 2005. Data was collected on patient comorbidity (Charlson Comorbidity Index [CCI], Lee Cardiac Risk Index [LCRI], National Institute on Aging and National Cancer Institute Comorbidity Index [NIA/NCI], and Adult Comorbidity Evaluation-27 [ACE-27]), systemic inflammatory response (Glasgow Prognostic Score [mGPS]), deprivation [Carstairs Deprivation Index], body mass index, and smoking status.
For cancer-specific survival, age (P = 0.047), tumor, node, metastasis system stage (P < 0.001), high-risk Petersen Index (P < 0.001), LCRI (P = 0.021), and mGPS (P < 0.001) were independent factors by multivariate analysis. For overall survival, age (P < 0.001), tumor, node, metastasis system stage (P = 0.001), high-risk Petersen Index (P = 0.002), postoperative infective complications (P = 0.002), ACE-27 (P = 0.008), and mGPS (P < 0.001) were independent factors. Older age related to increasing comorbidity (ACE-27, CCI, LCRI [P < 0.005]) and increased mGPS (P < 0.005). Smoking and deprivation related to increasing comorbidity (P < 0.05). The mGPS was associated with high comorbidity burden assessed with ACE-27 (P = 0.065), CCI (P = 0.016), LCRI (P = 0.095), and NIA/NCI (P = 0.084).
Comorbidity does not fully explain the relationship between the mGPS and cancer-specific survival in CRC patients. Furthermore, comorbidity, in particular that measured by the LCRI, is an important independent indicator of cancer survival.
除了肿瘤特征外，结直肠癌（CRC）的预后还取决于宿主因素，特别是全身炎症反应。这种与生存相关的关系的基础尚不清楚；然而，全身炎症可能反映合并症。本研究探讨了宿主因素（包括年龄、合并症、贫困和全身炎症）与 CRC 患者生存之间的关系。
本研究共纳入 302 例于 1997 年至 2005 年间接受根治性择期 CRC 切除术的患者。收集患者的合并症数据（Charlson 合并症指数[CCI]、Lee 心脏风险指数[LCRI]、国立衰老研究所和国家癌症研究所合并症指数[NIA/NCI]和成人合并症评估-27[ACE-27]）、全身炎症反应（格拉斯哥预后评分[mGPS]）、贫困（卡斯特斯贫困指数）、体重指数和吸烟状况。
在癌症特异性生存方面，年龄（P=0.047）、肿瘤、淋巴结、转移系统分期（P<0.001）、高危 Petersen 指数（P<0.001）、LCRI（P=0.021）和 mGPS（P<0.001）是多变量分析的独立因素。在总生存方面，年龄（P<0.001）、肿瘤、淋巴结、转移系统分期（P=0.001）、高危 Petersen 指数（P=0.002）、术后感染性并发症（P=0.002）、ACE-27（P=0.008）和 mGPS（P<0.001）是独立因素。年龄越大，合并症越严重（ACE-27、CCI、LCRI[P<0.005]），mGPS 越高（P<0.005）。吸烟和贫困与合并症增多有关（P<0.05）。mGPS 与 ACE-27（P=0.065）、CCI（P=0.016）、LCRI（P=0.095）和 NIA/NCI（P=0.084）评估的高合并症负担相关。
合并症并不能完全解释 mGPS 与 CRC 患者癌症特异性生存之间的关系。此外，合并症，特别是 LCRI 评估的合并症，是癌症生存的重要独立指标。
