The fibrinogen-to-albumin ratio (FAR), reflecting the systemic coagulation, nutritional and inflammation status of patients, has matured into a prognostic marker for several tumor types. However, only a few studies have assessed the utility of the FAR as a prognostic indicator in patients with advanced gastric cancer (GC) receiving first-line chemotherapy. In the present study, 273 patients with advanced GC who received first-line chemotherapy between January 2014 and January 2019 at the Cancer Hospital of China Medical University (Shenyang, China) were retrospectively analyzed. Using the cutoff values determined by receiver operating characteristic (ROC) analysis, the patients were divided into low-FAR (≤10.03) and high-FAR (>10.03), low-fibrinogen (<3.8 g/l) and high-fibrinogen (≥3.8 g/l), and low-albumin (<40.55 g/l) and high-albumin (≥40.55 g/l) groups. The associations of the pretreatment FAR and clinicopathological characteristics with progression-free survival (PFS) and overall survival (OS) were evaluated. In order to estimate the prognostic value of the FAR for patients with poor prognosis or normal fibrinogen and albumin levels, subgroup analyses were performed. The FAR had a higher area under the ROC curve (0.690; 95% CI: 0.628-0.752; P<0.001) compared with either fibrinogen or albumin alone, which are common indicators of coagulation, nutritional and inflammatory indices. A high FAR was significantly associated with a more advanced stage, peritoneal metastasis, increased CA72-4 levels and anemia (all P<0.05). On survival analysis, a low FAR was associated with a longer PFS and OS compared with a high FAR (202 vs. 130 days and 376 vs. 270 days, respectively; both P<0.001), while the hazard ratio (HR) and P-values of the FAR were lower compared with those of fibrinogen and albumin alone on multivariate analysis (PFS: HR= 0.638, 95% CI: 0.436-0.932, P= 0.020; OS: HR= 0.568, 95% CI: 0.394-0.819, P= 0.002). Subgroup analysis indicated that among patients with poor prognosis, including multiple metastases, TNM stage IV and abnormal CA72-4 levels, the FAR may be used as an accurate prognostic marker (all P<0.05), and may also reliably identify patients with poor prognosis among those with normal fibrinogen and albumin levels (all P<0.001). The FAR was indicated to be a valuable marker for predicting PFS and OS in patients with advanced GC receiving first-line chemotherapy and is superior to either fibrinogen or albumin alone.
Objective The objectives of this study were to analyze the difference between the preoperative radiological and postoperative pathological stages of colorectal cancer (CRC) and explore the feasibility of elastic lamina invasion (ELI) as a prognostic marker for patients with stage III colon cancer. Methods A total of 105 consecutive patients underwent radical surgery (R0 resection) for stage III colon cancer at the Cancer Hospital of China Medical University between January 2015 and December 2017. Clinicopathological features, including radiological stage and elastic lamina staining, were analyzed for prognostic significance in stage III colon cancer. Results A total of 105 patients with stage III colon cancer who met the criteria and had complete data available were included. The median follow-up period of survivors was 41 months. During the follow-up period, 33 (31.4%) patients experienced recurrence after radical resection, and the 3-year disease-free survival (DFS) rate was 64.8%. The consistency between preoperative radiological and postoperative pathological staging was poor (κ = 0.232, P < 0.001). The accuracy of ≤ T2 stage diagnoses was 97.1% (102/105), that of T3 stage was 60.9% (64/105), that of T4a stage was 68.6% (72/105) and that of T4b stage was 91.4% (96/105). The DFS rate of T3 ELI (+) patients was significantly lower than that of both T3 ELI (−) patients (P = 0.000) and pT4a patients (P = 0.013). The DFS rate of T3 ELI (−) patients was significantly higher than that of pT4b patients (P=0.018). T3 ELI (+) (HR (Hazard ratio), 8.444 [95% CI, 1.736–41.067]; P = 0.008), T4b (HR, 57.727[95% CI, 5.547-600.754]; P = 0.001), N2 stage (HR, 10.629 [95% CI, 3.858–29.286]; P < 0.001), stage III (HR, 0.136 [95% CI, 0.31–0.589]; P = 0.008) and perineural invasion (PNI) (HR, 8.393 [95% CI, 2.094–33.637]; P = 0.003) were independent risk factors for postoperative recurrence of stage III colon cancer. Conclusions The consistency between preoperative radiological and postoperative pathological staging was poor, especially for tumors located in the ascending colon and descending colon. Elastic lamina staining is expected to become a stratified indicator of recurrence risk for patients with stage III colon cancer and a guide for individualized adjuvant chemotherapy, thus improving patient prognosis.
Objective: The objectives of this study were to explore the feasibility of elastic lamina invasion (ELI) as a marker to evaluate the prognosis of stage III colon cancer patients.Methods: A total of 105 consecutive patients underwent radical surgery (R0 resection) for stage III colon cancer at the Cancer Hospital of China Medical University from January 2015 to December 2017. Clinicopathological features, including radiological stage and elastic lamina staining, were analysed for prognostic significance in stage III colon cancer.Results: A total of 105 patients with stage III colon cancer who met the criteria and had complete materials available were included. The median follow-up period of survivors was 41 months. During the follow-up period, 33 (31.4%) patients experienced recurrence after radical resection, and the 3-year disease-free survival (DFS) rate was 64.8%. The DFS rate of T3 ELI+ patients was significantly lower than that of T3 ELI- patients (P=0.000). The DFS rate of T3 ELI+ patients was significantly lower than that of pT4a patients (P=0.013). The DFS rate of T3 ELI- patients was significantly higher than that of pT4b patients (P=0.018). In the multivariate analysis, T3 ELI+ ([hazard ratio, HR], 8.444 [95% CI, 1.736-41.067]; P =0.008), N2 stage (HR,10.629[95% CI,3.858-29.286]; P<0.001), stage IIIC (HR, 0.136 [95% CI, 0.31-0.589]; P=0.008) and PNI (HR, 8.393 [95% CI, 2.094-33.637]; P=0.003) were independent risk factors for postoperative recurrence of stage III colon cancer.Conclusions: Elastic lamina staining is expected to become a stratified indicator of recurrence risk for patients with stage III colon cancer and can guide individualized adjuvant chemotherapy, improving patient prognosis.
