ABSTRACT

Objective:To investigate the expression of programmed death ligand 1 (PD-L1) in rectal cancer tissues and the correlation of PD-L1 expression with clinicopathological characteristics and overall survival of patients.Methods:The clinical data of 200 newly treated rectal cancer patients in Shanxi Provincial Cancer Hospital from January 2014 to December 2015 were retrospectively analyzed. The expression of PD-L1 in rectal cancer tissues was detected by immunohistochemistry. The correlations of PD-L1 expression with gender, age, tumor T stage, lymph node metastasis, tumor differentiation, histological type, tumor TNM stage, neutrophil-to-lymphocyte ratio (NLR) and overall survival of patients were analyzed.Results:The positive expression rate of PD-L1 was 24% (48/200). The positive expression rate of PD-L1 was high in patients with lymph node metastasis and high NLR (≥ 3.5) (both P < 0.05). The 5-year overall survival rate in PD-L1-positive group was 42%, and the PD-L1-negative group was 59%, and the difference between the two groups was statistically significant ( P < 0.05). The results of multivariate analysis showed that lymph node metastasis ( HR = 3.456, 95% CI 2.148-5.556, P < 0.01), NLR ≥ 3.5 ( HR = 1.871, 95% CI 1.169-2.996, P = 0.009), and PD-L1-positive expression ( HR = 2.187, 95% CI 1.373-3.484, P = 0.001) were independent adverse influencing factors for the overall survival of rectal cancer patients. Conclusion:PD-L1 is highly expressed in rectal cancer tissues, and the positive expression of PD-L1 is associated with poor overall survival of patients.

ABSTRACT

Objective:To investigate the influence of Jinshuibao tablet on immune function, therapeutic efficacy and safety in treatment of advanced lung squamous cell carcinoma patients treated by chemotherapy.Methods:The clinical data of 124 patients with stage Ⅳ lung squamous cell carcinoma who were admitted to Shanxi Provincial Cancer Hospital from January 2015 to December 2017 were retrospectively analyzed, including 60 patients treated by Jinshuibao tablet combined with chemotherapy (the observation group) and 64 patients treated by chemotherapy alone (the control group). The changes of immune function, therapeutic effect, and side effects were compared between the two groups.Results:The percentage of CD4 + cells after treatment [(33.4±8.9)% vs. (45.5±11.8)%, t = 2.71, P < 0.05] and CD4 +/CD8 + (0.9±0.3 vs. 1.5±0.4, t = 3.31, P < 0.05) in the observation group was increased compared with that before treatment, CD8 + cells was decreased compared with that before treatment [(30.9±8.6)% vs. (21.1±8.1)%, t = 2.42, P < 0.05], interferon-γ (IFN-γ) [(7.7±2.8)% vs. (14.1±2.4)%, t = 2.74, P < 0.05] and interleukin-2 (IL-2) [(8.8±3.2)% vs. (12.7±1.6)%, t = 2.96, P < 0.05] was increased compared with that before treatment. The percentage of CD3 + cells [(57.9±8.2)% vs. (45.2±10.8)%, t = 2.70, P < 0.05], CD4 + cells [(32.9±9.0)% vs. (22.8±9.6)%, t = 3.19, P < 0.05], NK cells [(14.9±3.1)% vs. (9.3±1.4)%, t = 2.97, P < 0.05] in the control group was decreased compared with that before treatment. Tumor necrosis factor α (TNF-α) was decreased compared with that before treatment [(6.8±1.4)% vs. (4.3±0.5)%, t = 3.23, P < 0.05]. There was a statistically significant difference in the level of T-cell subsets of both groups after treatment (all P <0.05); and the level of CD3 +, CD4 +, CD4 +/CD8 +, NK cells in the observation group was higher than that in the control group; CD8 + cell in the observation group was lower than that in the control group. There was no statistical difference in the level of IFN-γ, IL-2, TNF-α of both groups before treatment (all P > 0.05); the level of IFN-γ, IL-2, TNF-α in the observation group was higher than that in the control group after treatment, and the difference was statistically significant of both groups (all P < 0.05). The total effective rate of the observation group was higher than that in the control group, and the difference was statistically significant [31.3% (20/64) vs. 48.3% (29/60), χ 2 = 4.538, P = 0.033]; and the disease control rate in the observation group was higher than that in the control [56.3% (36/64) vs. 71.7% (43/60), χ 2 = 5.276, P = 0.022]. There was no significant difference between the two groups in adverse reactions of chemotherapy (all P > 0.05). Conclusion:Jinshuibao tablet combined with chemotherapy can improve the immune function and the efficacy of chemotherapy for patients with advanced lung squamous cell carcinoma.

ABSTRACT

Objective To investigate the diagnosis and treatment of anorectal malignant melanoma,in order to regulate surgical methods and explore multi-modality treatment.Methods Clinical pathological features,diagnosis and treatment procedures of 38 patients with anorectal melanoma were reviewed,and their correlation with prognosis were analyzed.Results In 38 patients,10 of them were male and 28 were female,with the mean age of 58.7 years old (ranged 28-75 years old).28 patients underwent abdominoperineal resection,10 patients underwent wide local excision.The 1-,3-,and 5-year disease-free survival rates were 64.9 %,18.5 % and 5.7 %,respectively.The 1-,3-,and 5-year overall survival rates were 85.8 %,24.1% and 6.4 %,respectively.Tumor thickness (≥ 1.51 rm) and tumor diameter (≥3 cm) were associated with lymph metastases (x2 =13.093,4.449,P =0.011,0.020),tumor thickness was also associated with distant metastases (x2 =11.965,P =0.018).According to the Kaplan-Meier method,comprehensive treatment after surgery had significant effects on disease-free survival (x2 =7.441,P =0.006).Tumor thickness,lymph metastases,and clinical staging had significant effects on overall survival (x2 =16.741,16.474,16.775,P =0.002,0.000,0.000).Cox proportional hazards model indicated that comprehensive treatment after surgery was the independent prognostic risk factors of disease-free survival (95 % CI 1.420-17.621,P =0.012).Tumor thickness and lymph metastases were the independent prognostic risk factors of overall survival (95 % CI 0.250-0.949,1.033-2.573,P =0.035,0.036).Conclusion Early detection,reasonable surgical procedure,generalized systemic focus on immunotherapy treatment are the key to improve quality of life and prolong the survival time of anorectal malignant melanoma patients.

ABSTRACT

Objective To study the growth effect of human cholangiocarcinoma cell line QBC939 treated by norcantharidin (NCTD) and preliminary illustrate the potential mechanism.Methods The human cholangiocarcinoma cell line QBC939 was detected by MTT assay,flow cytometry,immunocytochemistry after the treatment of NCTD in vitro.Results NCTD displayed inhibitory effect on growth of QBC939 from different doses of 0.125,0.75,2.5,10,120 μg/ml after 48 h (P <0.05).It was in a dose and time dependent manner.Dose-effect curve was drawn and IC50 value was (3.66±1.14) μg/ml.The flow cytometric profiles showed that the rate of cell apoptosis enhanced following increasing the concentration of NCTD[(8.6±0.4) %,(17.6±0.3) %,(22.9±0.4) %,(25.5±0.9) % and (31.1±1.5) %,respectively]and cells blocked in the G2/M phase after treatment with 2.5 μg/ml NCTD[(14.1±1.0) % and (5.7±0.3) %].The expression of the protein caspase-3 elevated after different concentrations of NCTD co-cultured with QBC939 compare with contrast group.Conclusion NCTD has an inhibitory effect on proliferation of QBC939 cell line,and the mechanism might be related to the induction of cell apoptosis and blockade of cell cycle.

ABSTRACT

Objective To study the effective evaluation of short peptide enteral nutrition powder in advanced digestive tract cancer. Methods 50 cases of advanced digestive tract cancer were randomly divided into two groups: experimental group(short peptide enteral nutrition powder) and control group(routine treatment). Results Data regarding to nutritional status and immune function (WT/IBW, TSF, MANC, ALB, TRF, PA, lgG, lgM, IgA, C3, CD3, CD4, CD8, CD4/CD8) showed a significant difference between experimental group and control group after two weeks's treatment,as well as between before and after two weeks's treatment in experimental group(P <0.05). Conclusion Short peptide enteral nutrition powder maintenance is beneficial to improve the nutritional status and the immune function of patients with advanced cancer and to promote their life quality.
