The combination of plasma fibrinogen and neutrophil lymphocyte ratio (F‐NLR) is a predictive factor in patients with resectable non small cell lung cancer

Abstract

The prognostic value of inflammation indexes in non small cell lung cancer (NSCLC) was not established. Therefore, we assessed the clinical applicability of the F-NLR score, which is based on fibrinogen (F) and the neutrophil-lymphocyte ratio (NLR), and the glasgow prognostic score (GPS) to predict the prognoses of NSCLC patients. We retrospectively identified 515 patients with stage I/II/IIIA who underwent surgery at our institution, and evaluated their preoperative serum levels of CRP, albumin, fibrinogen, neutrophil count, and the lymphocyte count. The cut-off values of the fibrinogen level and NLR were determined with receiver operating characteristic (ROC) curve. GPS was classified into three groups as previously described. The disease free survival (DFS) and overall survival (OS) were calculated by the Kaplan-Meier method. Categorical variables were compared using the χ test. Survival curves were estimated using the Kaplan-Meier method, and the Cox proportional hazard model was used to assess the prognostic factors. The F-NLR was significantly associated with sex (p = 0.000), smoking history (p = 0.014), lesion type (p = 0.000), histologic type (p = 0.000), T stage (p = 0.000), venous invasion (p = 0.000), lymphatic invasion (p = 0.000), and TNM stage (p = 0.000). The 5-year DFS rates in F-NLR groups 0, 1, and 2 were 46.7%, 36.4%, 30.1%, respectively (p = 0.000), and the 5-year overall survival (OS) rates in the above three groups were 52.0%, 39.8%, 32.1%, respectively (p = 0.000). Multivariate analysis showed that venous invasion (p = 0.036), lymph node metastasis (p = 0.000), and F-NLR (p = 0.034) were independent prognostic factors for DFS. Age (p = 0.015), venous invasion (p = 0.024), lymph node metastasis (p = 0.000), and F-NLR (p = 0.019) were independent prognostic factors for OS. Thus, F-NLR was the independent prognostic factor for both the DFS and OS. And patients with a high-risk preoperative F-NLR group may benefit from adjuvant therapy by subgroup analysis. Our results demonstrated that F-NLR, a novel inflammation-based grading system, as well as the GPS, appeared to have value as a promising clinical predictor of the prognosis for the resectable non small cell lung cancer patients.

Combination of preoperative fibrinogen concentration and neutrophil‑to‑lymphocyte ratio for prediction of the prognosis of patients with resectable breast cancer

“…The present study revealed a strong association between high F-NLR score and larger tumor size, nodal positivity, late TNM stage and lymphovascular invasion for resectable BC. These findings are consistent with the results of previous studies on gastric cancer (28) and NSCLC (27,33). Notably, the F-NLR score was identified as an independent predictor for DFS and OS in the present study, which is consistent with previous studies on various types of cancer (26)(27)(28)(29)(33)(34).…”

Fibrinogen/Albumin Ratio Index Is an Independent Prognosis Predictor of Recurrence-Free Survival in Patients After Surgical Resection of Gastrointestinal Stromal Tumors

“…Research evidence shows that hypoalbuminemia decreased BMI and decreased skeletal muscle volume are all associated with poor prognosis of malignant tumors (12,13). Besides, scoring systems that reflect inflammatory and immune levels constituting the plateletto-lymphocyte ratio (PLR), the prognostic nutritional index (PNI), and the neutrophil-to-lymphocyte ratio (NLR) are closely linked to the clinical outcomes of malignant cancers, including GIST (14)(15)(16)(17).…”

Association of preoperative systemic Immune-inflammation Index and Prognostic Nutritional Index with survival in patients with Upper Tract Urothelial Carcinoma

“…Preoperative malnutritional status is also closely related to postoperative survival outcomes in cancer patients [12]. Recently, several studies reported the potential role of novel indicators based on inflammatory and nutritional variables in patients with cancer [13][14][15]. The prognostic nutritional index (PNI), which is calculated from serum albumin level and lymphocyte counts, is one parameters that reflects preoperative nutritional status and has also been validated as an effective prognostic factor in various cancers, including UTUC [12,13].…”
