A Clinic-Epidemilogical Study of Cases of Locally Advanced Non Small Cell Lung Cancer (NSCLC) That Received Radiotherapy at NCI Cairo in the Period from 2001-2010

Purpose: This work was to study the clinic-epidemiological characteristics of patients with locally advanced NCSLC and to analyze their prognostic factors and also the results of different treatment modalities for local control and their effect on overall survival (OAS). Materials and Methods: This is a retrospective study including 121 patients with primary locally advanced NSCLC diagnosed between 2001 and 2010 at the radiotherapy department , National Cancer Institute, Cairo University, Egypt. Results: The study showed significant correlation between the tumor size 60, moderately differentiated tumors G2 and treatment outcomes;better locoregional control and better survival rates. On the opposite side poorly differentiated tumors G3, tumor size > 7 cm had the worst locoregional control and survival rates. The study also showed significant statistical correlation between treatment modality, locoregional control and survival rates. Patients who were treated by either concommitent chemo-radiotherapy or sequential chemo-radiotherapy had better local control compared to other patients who were treated by radical radiotherapy, and they also had the best survival rates among all the other treatment groups. The average 6 months OAS rates for all studied patients were 60.3% while 12 months survival rates were 38.8%. The median OAS was 7 months. Conclusions: From the present study, we concluded that concomitant chemo-radiotherapy is the treatment of choice for locally advanced non small cell lung cancer;also we concluded that better performance status and higher hemoglobin levels have better treatment outcome in these cases.

Pang Fuwan Uses Yao Medicine to Observe the Therapeutic Effects on the Physical and Mental Symptoms of Patients with Advanced Non-Small Cell Lung Cancer

Objective: Investigate the efficacy and safety of Yao Medicine in the treatment of advanced non-small-cell lung carcinoma, and explore the best therapeutic measure for clinical benefit. Methods: From July 2020 to July 2022, 84 patients with advanced non-small-cell lung carcinoma were selected and randomly divided into the Observation Group and control group, and the control group was treated with routine Western medicine, with 42 cases in each group. The activity of daily living (ADL) was assessed before and after treatment, meanwhile, the self-rating depression scale (SDS) and self-rating anxiety SAS (SAS) were used to assess the improvement of a bad mood, and quality of life SF-36 was used to assess the quality of life, to judge the efficacy and safety. Results: The effective rate of observation group was 91.67%. The effective rate of the control group was 76.19%. The effective rate of the observation group was significantly higher than that of the control group (P 0.05). There were no significant differences in the scores of SDS, SAS and quality of life between the two groups before treatment (P > 0.05), and after treatment, the scores of SDS, SAS and quality of life in the two groups were compared with those in the control group (P > 0.05), the scores of VAS, SDS and SAS decreased significantly, while ESCV, angle of straight leg elevation, ADL, physiological score, emotional score, social score and health status score increased significantly, the difference was statistically significant (P 0.05). Conclusion: Yao Medicine can improve the psychosomatic symptoms of patients with advanced non-small-cell lung carcinoma better, with better efficacy and higher safety.

Chemotherapy-free radiotherapy combined with immune checkpoint inhibitors:a new regimen for locally advanced non-small cell lung cancer?

Maintenance immunotherapy after concurrent chemoradiotherapy remains the standard therapeutic approach in patients with unresectable locally advanced non-small cell lung cancer(LA-NSCLC).The efficacy of pembrolizumab without chemotherapy in stage IV NSCLC has incited interest in similar approaches for LA-NSCLC.Several recent investigations involving the synergistic potential of immunotherapy combined with radiotherapy(i RT)have generated encouraging results.This review discusses the existing studies and prospective directions of chemotherapy-free i RT strategies in unresectable LA-NSCLC.Although the initial findings of chemotherapy-free i RT strategies have shown promising efficacy,we must consider the methodologic limitations of current studies and the myriad of challenges that accompany the implementation of chemotherapy-free i RT.These challenges include determining the optimal dose and fractionation,precise target volume delineation,and identification of additional suitable patient cohorts.Furthermore,the feasibility of chemotherapy-free i RT as a novel treatment modality for select patients with LA-NSCLC is contingent upon validation through randomized phase III trials.

Analysis and Review of Downregulated Actin Cytoskeletal Proteins in Non-Small Cell Lung Cancer

Actin, a highly conserved protein, plays a dominant role in Non-small cell lung cancer (NSCLC). Late diagnosis and the aggressive nature of NSCLC pose a significant threat. Studying the clinic pathological properties of NSCLC proteins is a potential alternative for developing treatment strategies. Towards this, 35 downregulated actin cytoskeletal proteins on NSCLC prognosis and treatment were studied by examining their protein-protein interactions, gene ontology enrichment terms, and signaling pathways. Using PubMed, various proteins in NSCLC were identified. The protein-protein interactions and functional associations of these proteins were examined using the STRING database. The focal adhesion signaling pathway was selected from all available KEGG and Wiki pathways because of its role in regulating gene expression, facilitating cell movement and reproduction, and significantly impacting NSCLC. The protein-protein interaction network of the 35 downregulated actin cytoskeleton proteins revealed that ACTG1, ACTR2, ACTR3, ANXA2, ARPC4, FLNA, TLN1, CALD1, MYL6, MYH9, MYH10, TPM1, TPM3, TPM4, PFN1, IQGAP1, MSN, and ZXY exhibited the highest number of interactions. Whereas HSPB1, CTNNA1, KRT17, KRT7, FLNB, SEPT2, and TUBA1B displayed medium interactions, while UTRN, TUBA1B, and DUSP23 had relatively fewer interactions. It was discovered that focal adhesions are critical in connecting membrane receptors with the actin cytoskeleton. In addition, protein kinases, phosphatases, and adapter proteins were identified as key signaling molecules in this process, greatly influencing cell shape, motility, and gene expression. Our analysis shows that the focal adhesion pathway plays a crucial role in NSCLC and is essential for developing effective treatment strategies and improving patient outcomes.

Clinical observation of gemcitabine and concomitant three-dimensional conformal radiotherapy in the treatment of locally advanced non-small cell lung cancer

Objective: To evaluate the clinical effect of gemcitabine and concurrent three-dimensional conformal radiation therapy (3D-CRT) for locally advanced non-small cell lung cancer (NSCLC) . Methods: From April 2002 to June 2005, 38 pa-tients with inoperable stage III NSCLC were treated with gemcitabine and 3D-CRT simultaneously. Chemotherapy consisted of intravenously gemcitabine 350 mg/m2 on days 1, 8, 15, 22, 29, 36. 3D-CRT was delivered up to a total dose of 60–64 Gy with a 2.0 Gy dose fraction per day, 5 days per week. Results: The overall response rates of primary tumor and mediastinum metastatic node were 86.8% (33/38) and 90.6% (29/32) respectively, and 91.7% (22/24) and 78.6% (11/14) for squamous cell carcinoma and adenocarcinoma respectively. The acute side effects of patients were mostly myelosuppression, nausea, vomiting, radiation-induced esophagitis and pneumonitis (RTOG I/II), however, all of them were cured. Conclusion: Con-current application of gemcitabine and 3D-CRT can improve the overall response rate for locally advanced NSCLC without aggravating the side effects.

Objective: To investigate the effects of Yiqi Gu decoction combined with DC chemotherapy on serum tumor markers, inflammatory factors and immune function in patients with locally advanced non-small cell lung cancer. Methods: A total of 95 patients with locally advanced non-small cell lung cancer were selected as the research objects, according to the random data table they were divided into control group (n=48) and observation group (n=47), patients in the control group were given DC chemotherapy, On the basis of this treatment, the patients in the observation group were given Yiqi Gu decoction treatment, Comparison of the levels of serum tumor markers [antigen (CEA) and carbohydrate antigen 19-9 (CA19-9)], inflammatory factor [C reactive protein (CRP) and tumor necrosis factor-α (TNF-α)] and immune function (CD3+, CD4+, CD8+, CD4+/CD8+)Results: Before treatment, there were no significant difference in the levels of CEA, CA19-9, CRP, TNF-α, CD3+, CD4+, CD8+, CD4+/CD8+ between the two groups;After treatment, the CEA, CA19-9, CRP, TNF-α, CD8+ levels of two groups were significantly lower than those in the same group before treatment, and the decreased range in observation group was significantly higher than the control group, moreover the levels after treatment were obviously lower than control group;After treatment, the levels of CD3+, CD4+, CD4+/CD8+ in the observation group were (64.72±5.25)% , (39.51±5.14)% and (1.35±0.27), which were significantly higher than the same group before treatment, and significantly higher than the control group [(58.57±5.09)%, (31.34±5.06)%, (1.14±0.33)], differences were statistically significant. Conclusion: DC chemotherapy combined with Yiqi Guben Decoction in the treatment of locally advanced non-small cell lung cancer, can effectively reduce the serum tumor marker levels, decrease inflammatory stress, improve immune function, has an important clinical value.

Impact of Cardiac Dose on Overall Survival in Lung Stereotactic Body Radiotherapy (SBRT) Compared to Conventionally Fractionated Radiotherapy for Locally Advanced Non-Small Cell Lung Cancer (LA-NSCLC)

Purpose: To examine possible association between heart irradiation and Overall Survival (OS) in lung SBRT patients and to compare observed associations with cardiac toxicity models previously derived in LA-NSCLC patient studies. Materials and Methods: 197 Patients treated with lung SBRT at Mayo Clinic Arizona were selected for this IRB-approved study. Multivariate Cox model with Akaike Information Criterion (AIC) was used to select patient specific covariates associated with OS. Heart dosimetry was represented by VD indices, which is a percentage of volume exposed to dose D or greater. Multivariate Cox models with patient specific covariates and single VD index per model was used to find a range of doses which were predictive for OS. A digital subdivision of the heart was further used to determine the spatial distribution of doses which were predictive for OS. A coarse subdivision divided heart into 4 segments, while the fine subdivision divided heart into 64 segments. Knowledge constrained Fused Lasso operator was used to derive a more complete model which correlated heart dosimetry with OS. Results of statistical analysis were compared to predictions of a model of cardiac toxicity in LA-NSCLC patients. Results: Higher age (p < 0.001), higher stage (p < 0.001) and squamous cell histology (p = 0.001) were associated with reduced OS. Whole heart DVH analysis did not reveal associations between heart irradiation and reduced OS. Coarse subdivision of the heart into four segments revealed that the irradiation of two inferior segments of the heart with low doses was associated with reduced OS, V2Gy in the right-inferior segment (HR = 1.012/1%, p = 0.02), and V1Gy in the left-inferior segment (HR = 1.01/1%, p = 0.04). Maximum dose in the right-inferior segment of the heart was also associated with reduced OS (HR = 1.02/Gy, p = 0.02). Fine subdivision of the heart into 64 segments revealed that approximately 25% of heart volume in the inferior part of the heart (15/64 segments), when irradiated to doses in the 1 Gy - 5 Gy range, were predictive for reduced OS (HR = 1.01/1%, p = 0.01). A previously derived model of cardiac toxicity in LA-NSCLC patients did not predict a reduction of OS due to heart irradiation in lung SBRT patients, because of relatively low doses to the heart in most lung SBRT patients. Conclusions: Doses lower than 5 Gy in the inferior segments of the heart may be associated with reduced overall survival in patients treated for lung lesions with SBRT. Stage and histology of the disease, as well as patients’ age, were also associated with overall survival. Comparisons of cardiac toxicity patterns in LA-NSCLC patients and lung SBRT patients suggest different etiology of cardiac toxicity in the two groups.

Effects of combined treatment of bronchial arterial chemoembolization and radioactive particle implantation on tumor markers and T lymphocyte subsets in locally advanced non-small cell lung cancer

Objective: To investigate the effects of bronchial arterial chemoembolization combined with radioactive particle implantation on the level of serum tumor markers and T lymphocyte subsets in patients with locally advanced non-small cell lung cancer. Methods: A total of 91 cases of locally advanced non-small cell lung cancer patients according to the random data table were divided into the control group (n=45) and observation group (n=46) according to the random data table. Patients in the control group was treated with bronchial arterial chemoembolization, on the basis of the control group, patients in the observation group were treated with radioactive particle implantation, the serum tumor markers and T lymphocyte subsets of the two groups were compared before and after treatment. Results: The levels of CEA, NSE, CA125, CD4+, CD8+, CD4+/CD8+ and NK in the two groups before the treatment were not statistically significant. Compared with the group before treatment, levels of CEA, NSE, CA125and CD8+ of the two groups after treatment were significantly decreased, and after treatment the level of CEA, NSE, CA125and CD8+ in the observation group was significantly lower than those of the control group;The levels of CD4+, CD4+/CD8+ and NK in the two groups after treatment were significantly higher than those in the group before treatment, and the observation group levels were significantly higher than those of the control group. Conclusion: Bronchial artery embolization combined with radioactive particle implantation for locally advanced non-small cell lung cancer, can effectively reduce the serum tumor markers level, improve the level of T cell subsets of patients, has important clinical value.

Nab-paclitaxel(abraxane)-based chemotherapy to treat elderly patients with advanced non-small-cell lung cancer:a single center,randomized and open-label clinical trial

Background： The purpose of this study is to evaluate the clinical efficacy and safety of abraxane-based chemotherapy with/without nedaplatin in elderly patients with non-small-cell lung cancer （NSCLC）. Materials and methods： From October 2009 to January 2013, 48 elderly patients （≥65 years） with NSCLC were investigated in this clinical trial. The patients were randomized and equally allocated into arms A and AP- （A） abraxane （130 mg/m2, days 1, 8）; （B） abraxane ＋ nedaplatin （20 mg/m2 days 1-3, q3w）. The parameters of objective response rate （ORR）, disease control rate （DCR）, progression-free survival （PFS）, overall survival （OS） and side effects were evaluated between two arms. Results： Over 80% of the patients completed four cycles of chemotherapy. The total ORR was 21.3 %, DCR was 55.3%, PFS 4.5 months and OS 12.6 months. No significant difference was found between arms A and AP in terms of ORR （16.7% vs. 26.1%, P=0.665） or DCR （55.3% vs. 56.5%, P=0.871）. The median PFS in arm A was 3.3 months [25-75% confidence interval （CI）： 3.1-7.2] and 5.5 months （25-75% CI： 3.2-7.0） in arm AP with no statistical significance （P=0.640）. The median OS in arm A was 12.6 months （25-75% CI： 5.7-26.2） and 15.1 months （25-75% CI： 6.4-35.3） in arm AP with no statistical significance （P=0.770）. The side effects were mainly grade 1-2. The incidence of grade 3-4 toxicities was 29.1% in arm A and 62.5% in arm AP with a statistical significance （P=0.020）. Conclusions： Compared with combined therapy, abraxane alone chemotherapy was beneficial for elderly NSCLC patients with better tolerability and less adverse events, whereas did not significantly differ in terms of ORR, DCR, PFS or OS.

Weekly albumin-bound paclitaxel/cisplatin versus gemcitabine/cisplatin as first-line therapy for patients with advanced non-small-cell lung cancer:A phase II open-label clinical study

Objective: The aim of this trial was to compare both the efficacy and the safety of a weekly nanoparticle albumin-bound paclitaxel(nab-paclitaxel) plus cisplatin vs. gemcitabine plus cisplatin in patients with advanced non-small-cell lung cancer(NSCLC).Methods: A total of 84 participants received either 100 mg/m^2 nab-paclitaxel each week on d 1, 8 and 15 of a 28 day cycle, as well as cisplatin 75 mg/m^2 on d 1 every three weeks(nab-TP arm); or gemcitabine 1,000 mg/m^2 on d 1 and 8, plus cisplatin 75 mg/m^2 on d 1 every three weeks(GP arm). The primary end point was progression-free survival(PFS). The secondary end points were overall response rate(ORR) and overall survival(OS).Results: According to our analysis, the median PFS was 4.8 months for the nab-TP arm vs. 5.2 months for the GP arm(P=0.55). Analysis showed the median OS was 14.6 months for participants who were in the nab-TP arm vs. 15.1 months for those in the GP arm(P=0.94). Besides, nab-TP showed OS advantages over GP in patients harboring epidermal growth factor receptor(EGFR) mutation(26.7 vs. 15.3 months, P=0.046) and patients with a performance status of 0(23.5 vs. 14.7 months, P=0.020). It was found that incidences of drug-related grade 3 or 4 toxicities were comparable between the two treatment arms.Conclusions: Therefore, it can be seen that weekly nab-TP treatment has a similar efficacy and tolerability to GP treatment for patients who are undergoing their first-line treatment for NSCLC. It could be that survival differences among platinum doublets in the context of both EGFR mutation and performance status have the potential to be the basis for our further clinical trials.

Nedaplatin/Gemcitabine Versus Carboplatin/Gemcitabine in Treatment of Advanced Non-small Cell Lung Cancer: A Randomized Clinical Trial

Objective： To evaluate the efficacy and safety of nedaplatin/gemcitabine （NG） and carboplatin/gemcitabine （CG） in the management of untreated advanced non-small cell lung cancer （NSCLC）. Methods： Sixty-two patients with previously untreated advanced NSCLC were recruited between June 2006 and November 2007. Subjects were randomly assigned to the NG arm （n=30） and the CG arm （n=32）. Only patients （24 and 25 in the NG and CG arms, respectively） who completed 〉2 chemotherapy cycles were included in the data analysis. The primary outcome measure was the objective response rate （ORR）. The secondary outcome measures included progression-free survival （PFS）, overall survival （OS） and adverse events. Results： There were no statistically significant differences in the efficacy measures （ORR, P=0.305; median PFS, P=0.298, median OS, P=0.961） or in the major adverse events （grade 3/4 neutropenia, P=0.666; grade 3/4 anemia, P=0.263; grade 3/4 thrombocytopenia, P=0.222） between the two treatment arms. However, there was a trend towards higher ORR （37.5% vs. 24.0%）, longer PFS （6.0 vs. 5.0 months）, and less adverse events in the NG arm. Conclusion： NG regimen seems to be superior over CG regimen for advance NSCLS, but further investigation is needed to validate this superiority.

Efficacy and safety evaluation of icotinib in patients with advanced non-small cell lung cancer

Objective： To evaluate the efficacy and safety of icotinib hydrochloride in patients with advanced non-small cell lung cancer （NSCLC）. Methods： A total of 89 patients with stage IIIB or IV NSCLC received icotinib at a dose of 125 mg administered 3 times a day. Icotinib treatment was continued until disease progression or development of unacceptable toxicity. Results： A total of 89 patients were assessable. In patients treated with icotinib, the overall response rate （RR） was 36.0% （32/89）, and the disease control rate （DCR） was 69.7% （62/89）. RR and DCR were significantly improved in patients with adenocarcinoma versus non-adenocarcinoma （P〈0.05）. The symptom improvement rate was 57.3% （51/89）, and the main symptoms improved were cough, pain, chest distress, dyspnea, and Eastern Cooperative Oncology Group performance status. The main toxic effects were rash [30/89 （33.7%）] and diarrhea [15/89 （16.9%）]. The level of toxicity was typically low. Conclusions： The use of icofinib hydrochloride in the treatment of advanced NSCLC is efficacious and safe, and its toxic effects are tolerable.

TT genotype of GNAS1 T393C polymorphism predicts better outcome of advanced non-small cell lung cancer patients

AIM: To evaluate the potential prognostic value of GNAS1 T393 C polymorphism in advanced non-small cell lung cancer.METHODS: We extracted genomic DNA from the peripheral blood leucocytes of 94 patients with advanced non-small cell lung cancer. Quantitative real-time polymerase chain reaction was used to determine the allelic discrimination. The correlation between genotype and overall survival was evaluated using the multivariate analysis and Kaplan-Meier approach.RESULTS: Thirty-eight out of 94(40%) patients displayed a TT genotype, 29 out of 94(31%) a CT genotype and 27 out of 94(29%) a CC genotype. The median survival of TT(25 mo) genotype carriers was longer than CT(12 mo) or CC(8 mo) genotype carriers. The favorable TT genotype predicted better overall survival(OS)(2-year OS: 48%; P =0.01) compared with CT(2-year OS: 18%) or CC(2-year OS: 15%) genotype. However, dichotomization between C-genotypes(CC + CT) and T-genotypes(TT) revealed significantly lower survival rates(2-year OS: 16%; P = 0.01) for C allele carriers.CONCLUSION: Our data provided strong evidence that the GNAS1 T393 C genetic polymorphism influenced the prognosis in advanced non-small lung cancer with a worse outcome for C allele carriers.

Sequential therapy according to distinct disease progression patterns in advanced ALK-positive non-small-cell lung cancer after crizotinib treatment

Objective: Crizotinib is recommended as the first-line therapy for advanced anaplastic lymphoma kinase(ALK)-positive non-small-cell lung cancer(NSCLC). Despite its initial efficacy, patients ultimately acquire resistance to crizotinib within 1 year. In such patients, the optimal sequential therapy after crizotinib treatment remains unknown. This study explored which sequential therapy option confers the greatest benefit.Methods: A total of 138 patients with advanced ALK-positive NSCLC resistant to crizotinib were studied. Based on patterns of disease progression of metastases, patients were divided into 3 groups: brain progression, non-liver progression, and liver progression. Sequential therapies included crizotinib continuation plus local therapy, nextgeneration ALK inhibitors(ALKi's), and chemotherapy. The primary endpoint was overall survival(OS) from the time of crizotinib resistance to death or last follow-up.Results: The 138 patients included 64 cases with progression in brain, 57 cases in non-liver sites and 17 cases in liver. A significant difference in OS was observed among the distinct progression pattern(median OS, 25.4 months in brain, 15.8 months in non-liver, and 10.8 months in liver, respectively, P=0.020). The difference in OS among sequential therapies was statistically significant in the non-liver progression group(median OS, 27.6 months with next-generation ALKi's, 13.3 months with crizotinib continuation, and 10.8 months with chemotherapy,respectively, P=0.019). However, crizotinib continuation plus local therapy seems to provide non-inferior median OS compared with next-generation ALKi's for patients with brain progression(median OS, 28.9 months vs.32.8 months, P=0.204). And no significant differences in OS were found in patients with progression in liver(P=0.061).Conclusions: Crizotinib continuation together with local therapy might be a feasible strategy for patients with progression in brain beyond crizotinib resistance, as well as next-generation ALKi's. Next-generation ALKi's tended to provide a survival benefit in patients with non-liver progression.

A phaseⅠtrial of an oral subtype-selective histone deacetylase inhibitor,chidamide,in combination with paclitaxel and carboplatin in patients with advanced non-small cell lung cancer

Objective： This phase I study was to evaluate safety, maximum tolerated dose, pharmacokinetics and preliminary antitumor activity of chidamide, a novel subtype-selective histone deacetylase （HDAC） inhibitor, in combination with paclitaxel and carboplatin in patients with advanced non-small cell lung cancer （NSCLC）. Methods： Ten patients received oral chidamide 20, 25, or 30 mg twice per week continuously with paclitaxel （175 mg/m2） and carboplatin [area under the curve （AUC） 5 mg/mL/min] administered in a 3-week cycle. Patients with response and stable disease after four cycles maintained chidamide monotherapy until disease progression or unacceptable toxicity. Blood samples were collected for pharmacoldnetic analysis after the first single oral of chidamide and first combination treatment in cycle 1 from all patients. Results： Two dose-limiting toxicities were recorded in the 30 mg cohort, including thrombocytopenia and prolonged neutropenia in the first cycle. Grade 3/4 neutropenia in any cycle was observed in all patients, but was not associated with significant complications. Other grade 3/4 hematologic toxicities included thrombocytopenia and leucopenia. No significant changes were observed in pharmacokinetic parameters for both chidamide and paclitaxel. One patient in the 20 mg cohort had confirmed partial response （PR）. Two out of 5 patients with brain metastases had intracranial complete remission after 4-cycle treatment. Conclusions： Chidamide combined with paclitaxel and carboplatin was generally tolerated without unanticipated toxicities or clinically relevant pharmacokinetic interactions. The recommended dose for chidamide in this combination was established at 20 mg, and a phase II trial is ongoing with this regimen in patients with advanced NSCLC.

Achievable complete remission of advanced non-small-cell lung cancer: Case report and review of the literature

Surgery is the first choice of treatment for patients with non-small-cell lung cancer(NSCLC), but few patients can be treated surgically because of either advanced disease or poor pulmonary function. Other therapies include radiotherapy and chemotherapy, as well as complementary and alternative therapies, usually with disappointing results. Bronchial artery infusion(BAI) is a manageable and effective method for treating advanced NSCLC. Outcome is good by BAI due to its repeatability and low toxicity. Icotinib hydrochloride is a newly developed and highly specific epidermal growth factor receptor(EGFR) tyrosine kinase inhibitor and has been safely and efficiently used to treat advanced NSCLC. We herein report a 73-year-old patient with chronic cough, who was diagnosed with advanced NSCLC with the EGFR mutation of L858 R substitution in exon 21, and treated with the combination of oral icotinib and BAI chemotherapy as the first-line therapy, which resulted in a satisfactory clinical outcome. Complete remission of advanced NSCLC can be achieved using the combination of oral icotinib and BAI chemotherapy.

Efficacy and safety of anlotinib plus S-1as thirdly-line or later-line treatmentin advanced non-small cell lung cancer

Objective Anlotinib,an oral vascular endothelial growth factor receptor 2(VEGFR2)inhibitor,has confirmed antitumor activity in lung cancer in both in vitro and in vivo assays,and has been recommended as third-line treatment agent in non-oncogene driven non-small cell lung cancer(NSCLC).This prospective study aimed to investigate the efficacy and safety of anlotinib plus S-1 for third-or later-line treatment in patients with advanced NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC,and documented disease progression following second-line chemotherapy,and/or epidermal growth factor receptor-tyrosine kinase inhibitor(EGFR-TKI)treatment were enrolled in this study.The patients were treated anlotinib(8 mg daily d 1–14)and S-1(60 mg/m^2 d 1–14)and the treatment was repeated every 3 weeks.Treatment was continued until disease progression or unacceptable toxicity occurred.The objective response rate(ORR),disease control rate(DCR),progression-free survival(PFS),and adverse events(AEs)were reviewed and evaluated.Results Forty-one patients were enrolled in the study between June 2018 and December 2018.The total ORR and DCR were 26.8%and 80.5%,respectively.The median PFS was 5.2 months[95%confidence interval(CI),3.9 to 6.6 months].In the univariate analysis,there was a significant difference in the median PFS between patients with brain metastases and those without brain metastases(4.8 months vs 5.9 months,respectively;P=0.039).The Eastern Cooperative Oncology Group(ECOG)performance status(P=0.002),lines of therapy(P=0.015),and therapeutic evaluation(P=0.014)were independent factors that influenced PFS.The most common AEs were hypertension,proteinuria,myelosuppression,gastrointestinal reactions,fatigue,and mucositis.Conclusion Anlotinib plus S-1 is an effective and safe regimen for advanced NSCLC as third-or later-line therapy.

Erlotinib usage after prior treatment with gefitinib in advanced non-small cell lung cancer: A clinical perspective and review of published literature

Erlotinib and gefitinib are among the most widely researched, used and available molecularly targeted therapies for treatment of advanced non-small cell lung cancer(NSCLC). They are both tyrosine kinase inhibitors(TKIs) of the epidermal growth factor receptor(EGFR). In the past decade, there have been reports on clinical benefit from use of erlotinib after gefitinib failure in NSCLC patients. A review of published literature on this focussed topic is provided herein. Pooled analysis of published literature shows that majority of patients were female(60.6%), non-smokers(64.5%), had adenocarcinoma histology(88.3%) and were of East Asian ethnicity(92.3%). Presence of sensitizing EGFR mutation was detected in 48.4% of subjects. Disease control rates with prior gefitinib therapy and with subsequent erlotinib treatment were 79.4% and 45.4% respectively. Based upon our review, the most important predictive factor for clinical benefit from erlotinib identified was previous response to gefitinib. The exact explanations for the potential benefit from erlotinib use in this patient population is still not known and further studies are required to determine the role of molecular mechanismsespecially those related to resistance to initial EGFR TKI therapy.
