Objective. To investigate the clinical significance of the mRNA expression of RRM1, TUBB3, and ERCC1 in non-small-cell lung cancer (NSCLC) tissues for the selection of adjuvant/postoperative chemotherapy regimens. Methods. Patients diagnosed with stage Ib-IIIa NSCLC were enrolled and randomly divided into a control group (undetected group) and an experimental group (detected group) after radical operation. The control group randomly received chemotherapy with gemcitabine plus cisplatin or paclitaxel plus cisplatin. The mRNA expression of RRM1, TUBB3, and ERCC1 was detected in the experimental group before chemotherapy, and based on the detected expression, the chemotherapy regimen of cisplatin plus gemcitabine or cisplatin plus paclitaxel was chosen. The disease-free survival (DFS) of the control group and experimental group was compared. Results. Pathological type, stage, gene expression detection, and treatment method were not significantly correlated with DFS ( P > 0.05 ). In the subgroups treated with gemcitabine, the median DFS was 17 months in the detected group and 10.5 months in the undetected group (hazard ratio = 0.2147, 95% confidence interval: 0.07909–0.5827, P = 0.0025 ). Multivariate regression analysis was performed to analyse whether gene expression detection was independently correlated with DFS in the subgroups treated with gemcitabine ( P = 0.025 ). In the detected group, the prognosis of patients with low expression of RRM1 was better than that of patients with high expression of RRM1 after paclitaxel treatment ( P = 0.0039 ). Conclusions. The selection of chemotherapy regimen based on mRNA expression of the RRM1, TUBB3, and ERCC1 genes may improve selection of candidate patients to receive clinical chemotherapy. However, large-scale prospective clinical studies are needed for in-depth investigation.

Objective The early detection of NSCLC is of importance because it provides chances for better outcomes. The aim of the study was to explore the clinical utility of EGFR and hTERT mRNA expression as markers for diagnosis of NSCLC. Methods EGFR and hTERT mRNA were quantified by quantative reverse transcription real time polymerase chain reaction in plasma of 45 non-small cell lung cancer (NSCLC) and 40 chronic obstructive pulmonary disease (COPD) patients, selected by certain spirometric characteristics that made them at high risk of developing lung cancer in future. Results The gene expression level of each gene was calculated and given as a relative quantity–-RQ. EGFR gene expression was found in all lung cancer patients. The mean level of expression was RQ = 29.39. hTERT mRNA could be detected in 88% of patients. The mean expression ratio in them was RQ = 17.31. Only 50% of the high risk patients turned to be positive for EGFR. The level of their expression was RQ = 2.09. The plasma levels of hTERT could be detected in 17 (42.5%) patients of the high risk COPD group. Their mean level of expression was RQ = 1.02. A statistically significant difference in EGFR and hTERT mRNA expression could be observed between the two groups of patients–-p = 0.0001. Conclusion EGFR and hTERT mRNA are potential markers for lung cancer diagnosis, whose clinical importance should be replicated in a larger cohort of patients.

Objective: To evaluate the effect of sintilimab combined with chemotherapy on tumor markers and immune function in advanced non-small cell lung cancer. Methods: The study was conducted at Xi’an Medical University, China. The 120 patients with advanced NSCLC who were treated in our hospital from January 2016 to January 2020 were randomly divided into two groups, with 60 cases in each group. Patients in the control group received conventional GP chemotherapy, while those in the experimental group received intravenous injection of sindilimab on the basis of conventional GP chemotherapy. The changes of serum tumor markers CYFRA211, CEA, CA125 and T lymphocyte subsets CD3+, CD4+, CD8+, CD4+/CD8+ in the two groups prior to and after treatment were compared and analyzed. At the same time, the clinical efficacy at six months was compared between the two groups. Results: The serum tumor markers CYFRA211, CEA and CA125 in the two groups after treatment were lower than those before treatment, and the difference was statistically significant (P=0.00). Specifically, the above-mentioned markers in the experimental group decreased more significantly than those in the control group, and the difference was statistically significant (CYFRA211, CA125, p=0.00; CEA, p=0.01; the levels of CD3+ and CD4+ in the experimental group were higher than those in the control group after treatment, with statistical significance (CD3+, p=0.00; CD4+, p=0.01)). No significant change can be seen in CD8+ (p=0.14), and the level of CD4+/CD8+ in the experimental group was higher than that in the control group, with a significant difference (p=0.02). The complete remission rate (CR) was 22% in the experimental group and 8% in the control group (P=0.04), which was statistically significant. The progress rate (PD) of the experimental group was significantly lower than that of the control group, with statistical significance (p=0.02). The overall response rate (RR) of the experimental group was more advantageous than that of the control group, with a statistically significant difference (p=0.01). Conclusion: Compared with chemotherapy alone, significant therapeutic effects can be obtained in the treatment of advanced non-small cell lung cancer with sintilimab combined with chemotherapy. With this combination regimen, the level of serum tumor markers can be significantly reduced, the cellular immune function of patients can be improved, with the overall response rate of treatment increased, and the risk of progressive disease of patients reduced. doi: https://doi.org/10.12669/pjms.37.4.3820 How to cite this:Liang X, Wei Z.

Summary Background Overexpression of apurinic/apyrimidinic endonuclease 1 (APE1) is an important cause of poor chemotherapeutic efficacy in advanced non-small cell lung cancer (NSCLC) patients. Gossypol, a new inhibitor of APE1, in combination with docetaxel and cisplatin is believed to improve the efficacy of chemotherapy for advanced NSCLC with high APE1 expression. Methods Sixty-two patients were randomly assigned to two groups. Thirty-one patients in the experimental group received 75 mg/m2 docetaxel and 75 mg/m2 cisplatin on day 1 with gossypol administered at 20 mg once daily on days 1 to 14 every 21 days. The control group received placebo with the same docetaxel and cisplatin regimen. The primary endpoint was progression-free survival (PFS); secondary endpoints included overall survival (OS), response rate, and toxicity. Results There were no significant differences in PFS and OS between the experimental group and the control group. The median PFS (mPFS) in the experimental and control groups was 7.43 and 4.9 months, respectively (HR = 0.54; p = 0.06), and the median OS (mOS) was 18.37 and 14.7 months, respectively (HR = 0.68; p = 0.27). No significant differences in response rate and serious adverse events were found between the groups. Conclusion The experimental group had a better mPFS and mOS than did the control group, though no significant difference was observed. Because the regimen of gossypol combined with docetaxel and cisplatin was well tolerated, future studies with larger sample sizes should be performed.

Objectives: To evaluate the clinical effect of apatinib combined with chemotherapy in the treatment of advanced non-small cell lung cancer (NSCLC). Methods: Eighty patients with advanced NSCLC treated in Hebei General Hospital from January 2017 to July 2020 were randomly divided into two groups: the experimental group and the control group, each with 40 cases. Patients in the control group were treated with conventional paclitaxel combined with cisplatin chemotherapy, while patients in the experimental group were treated with apatinib mesylate tablets based on the treatment of the control group. After treatment, tumor efficacy evaluation was conducted on all patients every two cycles, and the therapeutic effect, adverse drug reactions, improvement of quality-of-life scores prior to and after treatment, and changes of indicators such as tumor markers carcinoembryonic antigen (CEA) and carbohydrate antigen 153(CA153) were compared and analyzed between the two groups.  Results: The total effective rate of the experimental group was 67.5%, which was significantly better than the 45% of the control group (p=0.04); The incidence of adverse drug reactions in the experimental group was 25%, while that in the control group was 37.5%, with no significant difference (p=0.23); Moreover, the improvement rate of quality of life scores in the experimental group was significantly higher than that in the control group (p=0.03), and the levels of CEA and CA153 in the experimental group were significantly lower after treatment than those in the control group, with a statistically significant difference (p=0.01). Conclusion: Apatinib combined with conventional chemotherapy is effective in the treatment of advanced non-small cell lung cancer, the quality of life can be significantly improved, tumor markers can be significantly reduced, and adverse reactions will not be significantly increased. doi: https://doi.org/10.12669/pjms.37.4.4066 How to cite this:Cui Y, Liu J, Liu M, Zhang H.

Abstract Objective: To analyze the morbidity and mortality of non-small cell lung cancer and evaluate treatment strategies for non-small cell lung cancer patients in low-risk areas of the COVID-19.Materials and methods: We selected patients in the hospital in Sichuan Science City Hospital from September 2019 to February 2020 as research subjects and divided them into experimental and control groups. The evaluation of treatment strategy was based on morbidity and mortality.Results: There were 9010 patients hospitalized. The total morbidity was 0.699%, which was 0.504% in the control group and 0.991% in the experimental group (P=0.024). The total mortality was 0.887 /103, which was 0.840/103 in the control group (4/4764) and 0.942/103 in the experimental group (P=0.998). The patients discontinued therapy or follow-up and cancer progression in the experimental group was significantly higher than that in the control group (P＜0.001, =0.007). Most of the discontinued and progressive cancer patients were elderly and in late stage.Conclusion: The morbidity of NSCLC during the COVID-19 pandemic was significantly high. The mortality in the experimental group was slightly higher than that in the control group, while the difference in cancer progression was significant. It is practicable to perform surgery for early-stage NSCLC patients and undesirable to suspend treatment for late-stage patients in low-risk areas.

AbstractObjective: To study the therapeutic effect of Kanglaite injection combined with chemotherapy in the treatment of late stage non-small cell lung cancer (NSCLC), and also to observe the effect of the combination treatment on immune function. Methodology: 92 patients with advaned stage of non-small cell lung cancer who admitted to First Hospital of ZiBo city hospital from May 2017 to October 2018 were randomly divided into experimental group and control group, with 46 cases respectively. The control group was treated with chemotherapy only while the experimental group was treated with Kanglaite injection combined with chemotherapy which was the basic treatment for patients, and the total treatment effective rate, adverse reaction rate and immune index of the treatments on two groups were compared. Result: The total treatment effective rate of the experimental group was 80.43%, which was significantly higher than that of the control group, which was 63.04%. The incidence of adverse reactions in the experimental group was 36.96%, which was lower than that of the control group (78.26%). The immune indexes of the experimental group (CD3+, CD4+, IgG, IgA) were better than that of the control group, respectively. The differences between the two groups were statistically significant (P<0.05).Conclusion: During the chemotherapy of late stage or advanced non-small cell lung cancer, the addition use of Kanglaite injection has a significant effect on improving tumor control and reducing the side effects of chemotherapy, and helps to improve the immune function of patients, thus it is worth promoting.

Corticosteroid Administration

Introduction: Corticosteroids are used to treat immune-related adverse events (irAEs) associated with nivolumab. However, patients with non-small-cell lung cancer who are administered corticosteroids before the initiation of nivolumab treatment are commonly excluded from clinical trials. The appropriate timing for corticosteroid administration in relation to nivolumab treatment, effects of corticosteroids on the efficacy of nivolumab, and resulting adverse events are not clearly understood. In this study, the effects of differences in the timing of corticosteroid administration on nivolumab efficacy and the resulting adverse events were examined. Methods: A retrospective study was conducted with 109 patients who were treated with nivolumab at Sapporo Minami-Sanjo Hospital between December 2015 and March 2018. Results: Of the 109 patients treated with nivolumab, 12 patients were administered corticosteroids before the first cycle of nivolumab (pre-CS), and 33 patients were administered corticosteroids after the first cycle of nivolumab (post-CS). These 2 groups were compared with the control group comprising 64 patients who were not administered corticosteroids (non-CS). The objective response rate in the post-CS group was significantly higher than that in the non-CS group, and the disease control rate in the pre-CS group was significantly lower than that in the non-CS group. The overall survival time and progression-free survival time in the pre-CS group were significantly shorter than those observed in the non-CS group; however, these did not differ from those in the post-CS group. Conclusions: These results suggest that corticosteroids administered to patients with non-small-cell lung cancer after initiation of nivolumab treatment did not affect the disease prognosis. Thus, corticosteroids can be administered immediately for rapid treatment of irAEs.
