Relevance of EGFR gene mutation with pathological features and prognosis in patients with non-small-cell lung carcinoma

Objective:To study the relevance of EGFR gene mutation with pathological features and prognosis in patients with non-small-cell lung carcinoma.Methods:A total of 297 patients from July 2009 to May 2013 were chosen as objects.EGFR gene mutation were detected with fluorescence quantitative PCR.Relevance of EGFR gene mutation with clinical and pathological features was analyzed,and the prognosis of EGFR- mutant-patients and that of EGFR- wide type-patients was compared.Results:In 297 patients.136(45.79%) showed EGFR gene mutation.EGFR gene mutation had no significant relevance with age.gender,smoking history,family history of cancer and clinical stage(P>0.05);there was significant relevance between EGFR gene mutation and blood type,pathologic types,differentiation and diameter of cancer(P<0.05).The difference between prognosis of EGFR- mutant-patients and that of EGFR- wide type-patients was statistical significance(P<0.05).Conclusions:EGFR gene mutation has significant relevance with pathological features,the prognosis of EGFRmutant-paticnts is better than that of EGFR- wide type-patients.

Complete pathological response in locally advanced non-small-cell lung cancer patient: A case report

BACKGROUND Chemotherapy and radiotherapy followed by durvalumab is currently the standard treatment for locally advanced node-positive non-small-cell lung cancer(NSCLC).We describe the case of a patient with locally advanced node-positive NSCLC(LA-NSCLC)treated in a phase II prospective protocol with chemotherapy,accelerated hypofractionated radiotherapy(AHRT)and surgery in the preimmunotherapy era.CASE SUMMARY A 69-year-old male,ex-smoker(20 PY),with a Karnofsky performance status of 90,was diagnosed with locally advanced squamous cell lung carcinoma.He was staged by total body computed tomography(CT)scanning,and integrated 18Ffluorodeoxyglucose positron emission tomography/CT scan[cT4 cN3 cM0,stage IIIC according to TNM(tumor-node-metastasis)8th edition]and received AHRT between chemotherapy cycles,in accordance with the study protocol(EudractCT registration 2008-006525-14).At the end of the study the patient underwent surgery,which was not part of the protocol,and showed a complete pathological response.CONCLUSION This case report confirms that AHRT can be used successfully to treat primary LA-NSCLC with bilateral mediastinal lymph node involvement.Our case is of particular interest because of the pathological response after AHRT and the lack of surgical complications.We hypothesize that this radiotherapeutic approach,with its proven efficacy,could be delivered as a short course reducing treatment costs,increasing patient compliance and reducing toxicity.We are currently investigating the possibility of combining hypofractionation,chemotherapy and immunotherapy for patients with LA-NSCLC.

Effect of compound Kushen injection on T-cell subgroups and natural killer cells in patients with locally advanced non-small-cell lung cancer treated with concomitant radiochemotherapy

OBJECTIVE: To observe effect of compound Kushen injection on T-cell subgroups and NK cells in patients with locally advanced non-small-cell lung cancer(NSCLC) treated with concomitant radiochemotherapy.METHODS: We randomly divided 60 patients with locally advanced NSCLC who were treated at our hospital between May 2011 and May 2013 into a treatment group and a control group by drawing.The treatment group(n = 30) received concomitant radiochemotherapy plus compound Keshen injection, and the control group(n = 30) received only radiochemotherapy.RESULTS: After treatment, levels of CD3+, CD4+,CD4 +/CD8 + and CD16 +/CD56 + cells had significantly increased, and CD8 + cells had significantly decreased, in the treatment group compared with both their pretreatment levels and with levels in the control group. In the control group, post-treatment levels of CD3 +, CD4 +, CD4 +/CD8 + and CD16+/CD56+ cells were not significantly changed from pretreatment levels. The two groups did not significantly differ in their rates of toxicity reactions(P > 0.05).CONCLUSION: Compound Kushen injections can increase immunologic function in patients with locally advanced non-small cell lung cancer who receive concomitant radiochemotherapy.

Clinical observation of Yiqi Qingdu Prescription(益气清毒方)on the treatment of intermediate-stage and advanced non-small-cell lung cancer

OBJECTIVE:To observe the effects of the Yiqi Qingdu prescription(益气清毒方)on intermediate-stage and advanced non-small-cell lung cancer(NSCLC).METHODS:In total,300 patients with intermediate-stage or advanced NSCLC were randomly and equally divided into three groups using computer-generated random numbers as follows:Western medicine(WM),Chinese medicine(CM),and integrated Traditional Chinese and Western Medicine(IM).After 3 months of treatment,the overall response rate(ORR);disease control rate(DCR);symptom score(SS);Karnofsky performance status(KPS);adverse event score;counts of CD3^(+),CD4^(+),and CD8^(+)cells;CD4^(+)/CD8^(+)ratio;and carcinoembryonic antigen(CEA)level were compared among the groups.RESULTS:The ORRs were 30.36%,20.24%,and 7.87%in the IM,CM,and WM groups,respectively,whereas the DCRs were 85%,75%,and 73%,respectively.Compared to the CM group,the ORR was significantly higher in the WM and IM groups,whereas the DCR was significantly higher in the IM group(all P<0.05).SS was obviously higher in the WM group than in the other two groups(both P<0.01).KPS was significantly lower in the WM group after treatment(P=0.005).The mean number of adverse events was significantly lower in the CM(2.2±1.3)and IM(2.4±1.3)groups than in the WM group(4.6±1.7,both P<0.05).CD3^(+)cell counts were significantly decreased in the WM group(P=0.031).In the IM group,CD8^(+)cell counts were increased after treatment,whereas the CD4^(+)/CD8^(+)ratio was decreased(both P<0.01).Compared with the WM group,CD3^(+)(P=0.01),CD4^(+)(P=0.044),and CD8^(+)(P=0.009)cell counts were significantly higher in the IM group,whereas the CD4^(+)/CD8^(+)ratio was significantly lower(P=0.011).Relative to the CM group,CD8^(+)cell counts were significantly higher(P=0.001)and the CD4^(+)/CD8^(+)ratio was significant ly lower in the IM group(P=0.001).CEA levels were significantly increased in the CM group(P=0.023).CONCLUSION:The Yiqi Qingdu prescription can improve the outcomes of WM in patients with NSCLC.
