Preoperative Neutrophil-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and CEA as the Potential Prognostic Biomarkers for Colorectal Cancer.

Background: This study was to evaluate the prognostic value of the preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and carcinoembryonic antigen (CEA) in colorectal cancer (CRC) patients and to identify the potential and easily accessible prognostic biomarkers for CRC. Methods: We retrospectively reviewed altogether the records of 330 CRC patients according to inclusion criteria. The clinical characteristics include age at diagnosis, body mass index (BMI), preoperative CEA level, neutrophil , lymphocyte, and platelet count, tumor primary site and size, clinical pathological TNM stage, and survival status were recorded through the review of medical records. The overall survival (OS) was calculated using the Kaplan-Meier method. The Cox proportional hazards model was used for the univariate and multivariate analysis to evaluate the prognostic factors of CRC. Results: A total of 330 patients were finally included in the current study. The mean follow-up duration was 32.8 ± 19.1 months (range, 0.1-67.7). Compared with the median OS, preoperative high NLR, PLR, and CEA, and low BMI had lower median OS. The NLR and PLR value rise indicates lower median OS in stage I-II CRC; however, the NLR value and CEA level rise indicates lower median OS in stage III-IV CRC. Preoperative high NLR, PLR, and CEA level and low BMI have poorer OS by univariate analysis. By multivariate analysis, the age, sex, N, M stage, and BMI demonstrated independently influence the OS of CRC. NLR was an independent predictor of stage I-II CRC, and the CEA level was an independent predictor of stage III-IV CRC. Conclusions: Our results show that preoperative high NLR, PLR, CEA, and low BMI had poorer OS, NLR was an independent predictor of stage I-II CRC, and the CEA level was an independent predictor of stage III-IV CRC.

The application effect and safety analysis of TACE combined with HIFU ablation in the comprehensive treatment of middle and advanced liver cancer / 中国医学装备

Objective: To explore the effect of transcatheter arterial chemoembolization(TACE) combined with high intensity focused ultrasound (HIFU) ablation on patients with middle and advanced liver cancer and to analyze its anti-tumor value. Methods: 126 patients with middle and advanced liver cancer who received palliative treatment were selected in the research. According to the different treatment program, they were divided into TACE groups (66 cases) which patients received TACE and TACE combined with HIFU ablation group (60 cases) which patients received the treatment of TACE combined with HIFU ablation. After 4 weeks of treatment, the therapeutic effect of solid tumor and the change of immune function indicator of the two groups were compared. At the same time, the results of follow-up visit were recorded, and adverse reaction of antineoplaston and survival situation were further compared. Results:After treatment, the immune function both of two groups were enhanced, and the cluster of differentiation (CD)3+, CD4+, and CD4+/ CD8+of TACE combined with HIFU ablation group was significantly higher than that of TACE group (t=6.303, t=6.049, t=2.148, P<0.05). While the clinical benefit rate of TACE combined with HIFU ablation group was significantly higher than that of TACE group (Z=2.975, P<0.05), and the survival rate of 1 year and survival rate of 2 years of TACE combined with HIFU ablation group were significantly higher than that of TACE group (x2=3.99, x2=4.33, P<0.05), respectively. On the other hand, the differences of complications, included skin burn, liver function damage and abdominal discomfort, between the two groups were no significant (x2=2.235, x2=0.847, x2=0.019, P>0.05). Conclusion:The technique of TACE combined with HIFU ablation can enhance immune function and the therapeutic effect of antineoplastic, and its advantages includes obvious effect of antineoplastic and safety of usage. Therefore, its application value should be paid higher attention in oncotherapy of solid tumor as this paper's suggestion.
