Abstract Background The development and progression of cancer cachexia are connected to systemic inflammation and physical performance. However, few relevant studies have reported the survival outcomes prediction of systemic inflammation and physical performance in patients with colorectal cancer (CRC) cachexia. This study investigated the prognostic prediction value of systemic inflammation and performance status in patients with CRC cachexia. Methods This multicentre cohort study prospectively collected 905 patients with CRC (58.3% males, 59.3 ± 11.5 years old). Cancer cachexia was diagnosed according to the 2011 Fearon Cachexia Diagnostic Consensus. The prognostic value of systematic inflammatory indicators was determined using the area under the curve, concordance index, and multivariate survival analysis. Performance status was evaluated with Eastern Coopertive Oncology Group performance score (ECOG‐PS). Survival data were analysed using univariate and multivariate Cox regression analyses. Results The area under the curve, concordance index and survival analysis showed that C‐reactive protein (CRP), lymphocyte to CRP ratio (LCR) and CRP to albumin ratio (CAR) were more stable and consistent with the survival of patients with CRC, both in non‐cachexia and cachexia populations. Among patients with CRC cachexia, high inflammation [low LCR, hazard ratio (HR) 95% confidence interval (95% CI) = 3.33 (2.08–5.32); high CAR, HR (95% CI) = 2.92 (1.88–4.55); high CRP, HR (95% CI) = 3.12 (2.08–4.67)] indicated a worse prognosis, compared with non‐cachexia patients [low LCR, HR (95% CI) = 2.28 (1.65–3.16); high CAR, HR (95% CI) = 2.36 (1.71–3.25); high CRP, HR (95% CI) = 2.58 (1.85–3.60)]. Similarly, among patients with CRC cachexia, high PS [ECOG‐PS 2, HR (95% CI) = 1.61 (1.04–2.50); ECOG‐PS 3/4, HR (95% CI) = 2.91 (1.69–5.00]) indicated a worse prognosis, compared with patients with CRC without cachexia [ECOG‐PS 2, HR (95% CI) = 1.28 (0.90–1.81); ECOG‐PS 3/4, HR (95% CI) = 2.41 (1.32–4.39]). Patients with CRC cachexia with an ECOG‐PS score of 2 or 3–4 and a high inflammation had a shorter median survival time, compared with patients with an ECOG‐PS score of 0/1 and a low inflammation. Conclusions The systemic inflammatory markers LCR, CAR and CRP have stable prognostic values in patients with CRC. The ECOG‐PS may be an independent risk factor for CRC. Combined evaluation of systemic inflammation and ECOG‐PS in patients with CRC cachexia could provide a simple survival prediction.

Abstract Background Changes in body composition and systemic inflammation are important characteristics of cancer cachexia. This multi‐centre retrospective study aimed to explore the prognostic value of the combination of body composition and systemic inflammation in patients with cancer cachexia. Methods The modified advanced lung cancer inflammation index (mALI), which combines body composition and systemic inflammation, was defined as appendicular skeletal muscle index (ASMI) × serum albumin/neutrophil‐lymphocyte ratio. The ASMI was estimated according to a previously validated anthropometric equation. Restricted cubic splines were used to evaluate the relationship between mALI and all‐cause mortality in patients with cancer cachexia. Kaplan–Meier analysis and Cox proportional hazard regression analysis were used to evaluate the prognostic value of mALI in cancer cachexia. A receiver operator characteristic curve was used to compare the effectiveness of mALI and nutritional inflammatory indicators in predicting all‐cause mortality in patients with cancer cachexia. Results A total of 2438 patients with cancer cachexia were enrolled, including 1431 males and 1007 females. The sex‐specific optimal cut‐off values of mALI for males and females were 7.12 and 6.52, respectively. There was a non‐linear relationship between mALI and all‐cause mortality in patients with cancer cachexia. Low mALI was significantly associated with poor nutritional status, high tumour burden, and high inflammation. Patients with low mALI had significantly lower overall survival (OS) than those with high mALI (39.5% vs. 65.5%, P

Abstract Background Although systemic inflammation is an important feature of the cancer cachexia, studies on the association between systemic inflammation and prognostic of cancer cachexia are limited. The objective of this study is to evaluate whether the neutrophil‐to‐lymphocyte ratio (NLR) is associated with outcome and quality of life for patients with cancer cachexia and investigated any interaction between NLR and the clinical parameters. Methods This is a multicentre cohort study of 2612 cancer patients suffering from cachexia diagnosed between June 2012 and December 2019. The main parameters measured were overall survival (OS) time and all‐cause mortality. The association between NLR and all‐cause mortality was evaluated using hazard ratios (HRs) and the restricted cubic spline model with a two‐sided P‐value. Optimal stratification was used to solve threshold points. We also evaluated the cross‐classification of NLR for each variable of survival. Results Of the 2612 participants diagnosed with cancer cachexia, 1533 (58.7%) were male, and the mean (SD) age was 58.7 (11.7) years. Over a median follow‐up of 4.5 years, we observed 1189 deaths. The overall mortality rate for patients with cancer cachexia during the first 12 months was 30.2% (95%CI: 28.4%–32.0%), resulting in a rate of 226.07 events per 1000 patient‐years. An increase in NLR had an inverted L‐shaped dose–response association with all‐cause mortality. The optimal cut‐off point for NLR as a predictor of mortality in cancer patients with cachexia was 3.5. An NLR of 3.5 or greater could independently predict OS (HR, 1.51, 95%CI: 1.33–1.71). These associations were consistent across subtypes of cancer. Several potential effect modifiers were identified including gender, BMI, tumour type, KPS score and albumin in content. Increasing NLRs were independently associated with a worsening in the majority of EORTC QLQ‐C30 domains. Elevated baseline NLR was associated with low response and poor survival in patients treated with immunotherapy. Conclusions The baseline NLR status was found to be a significant negative prognostic biomarker for patients with cachexia; this effect was independent of other known prognostic factors.

Abstract Background Systemic inflammation and cachexia are associated with adverse clinical outcomes in elderly patients with cancer. The Geriatric Nutritional Risk Index (GNRI) is a simple and useful tool to assess these conditions, but its predictive ability for elderly patients with cancer cachexia (EPCC) is unknown. Methods This multicentre cohort study included 746 EPCC with an average age of 72.00 ± 5.24 years, of whom 489 (65.5%) were male. The patients were divided into two groups (high GNRI group ≥91.959 vs. low GNRI group
