Lung cancer is the leading cause of cancer-related deaths with high morbidity and mortality. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for 85% of all cases. Fortunately, the development of molecular oncology provides a promising and effective therapeutic strategy for lung cancers, including specific gene mutations/translocations and immune checkpoints, with epidermal growth factor receptor (EGFR) common mutations first and anaplastic lymphoma kinase (A ...[more]

Project description:BackgroundWhile prospective clinical studies on immunotherapy in epidermal growth factor receptor (EGFR) mutant non-small-cell lung cancer (NSCLC) with acquired resistance to EGFR tyrosine kinase inhibitors (TKIs) are ongoing, this study aimed to investigate the outcomes of immunotherapy combinations in such a population in a real-world setting.MethodsThe clinical data of pretreated EGFR-mutated NSCLC patients who acquired EGFR-TKI resistance and received immunotherapy were retrospectively analyzed in this study. Progression-free survival (PFS) was assessed using the Kaplan-Meier log-rank test, and univariate and multivariate analysis were performed.ResultsA total of 31 patients were analyzed in this study. A total of 25 (80.6%) patients received combination immunotherapy. In the univariate analysis, patients who received combination immunotherapy seemingly acquired longer PFS than those who received monotherapy, although there was no significant difference (3.42 months vs. 1.61; P = 0.078; hazard ratio (HR) 0.43, 95% CI: 0.16-1.13). Patients who received antiangiogenic drugs prior to immunotherapy acquired better PFS (3.42 months vs. 1.58; P = 0.027; HR 0.37, 95% CI: 0.15-0.93), while patients with liver metastasis had inferior PFS (2.04 months vs. 3.42; P = 0.031; HR 2.83, 95% CI: 1.05-7.60). Furthermore, multivariate analysis confirmed that the above three factors had independent prognostic value.ConclusionsThe study revealed that immunotherapy combinations are better choices than single-agent regimens in previously treated and EGFR-mutant NSCLC patients with progressive disease. In addition, antiangiogenic drugs administered before immunotherapy might be a favorable prognostic factor, while liver metastasis was associated with a short PFS in this setting. In future, more robust and prospective clinical trial results are expected to guide clinical practice.Key pointsSignificant study findings Immunotherapy-based combination therapies are better choices than single-agent regimens in heavily treated EGFR-mutant NSCLC patients. What this study adds Patients without liver metastasis and with prior antiangiogenic drugs obtained more benefit from immunotherapy in this setting.

Project description:BackgroundThe prognostic significance of TP53 concurrent mutations in patients with epidermal growth factor receptor (EGFR)- or anaplastic lymphoma kinase (ALK)- mutated advanced non-small-cell lung cancer (NSCLC) who received EGFR-tyrosine kinase inhibitors (TKIs) or ALK-TKIs based targeted therapy remains controversial. Therefore, the present meta-analysis was performed to investigate the association between TP53 concurrent mutations and prognosis of patients with advanced NSCLC undergoing EGFR-TKIs or ALK-TKIs treatments.MethodsEligible studies were identified by searching the online databases PubMed, Embase, Medline, The Cochrane library and Web of Science. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated to clarify the correlation between TP53 mutation status and prognosis of patients. This meta-analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.ResultsIn total, 15 studies with 1342 patients were included for final analysis. Overall, concurrent TP53 mutation was associated with unfavorable progression-free survival (PFS) (HR = 1.88, 95%CI: 1.59-2.23, p < 0.001, I2 = 0.0%, P = 0.792) and overall survival (OS) (HR = 1.92, 95%CI: 1.55-2.38, p < 0.001, I2 = 0.0%, P = 0.515). Subgroup analysis based on type of targeted therapy (EGFR-TKIs or ALK-TKIs, pathological type of cancer (adenocarcinoma only or all NSCLC subtypes) and line of treatment (first-line only or all lines) all showed that TP53 mutations was associated with shorter survivals of patients with EGFR-TKIs or ALK-TKIs treatments. Particularly, in patients with first-line EGFR-TKIs treatment, significantly poorer prognosis was observed in patients with TP53 concurrent mutations (pooled HR for PFS: 1.69, 95% CI 1.25-2.27, P < 0.001, I2 = 0.0%, P = 0.473; pooled HR for OS: 1.94, 95% CI 1.36-2.76, P < 0.001, I2 = 0.0%, P = 0.484). Begg's funnel plots and Egger's tests indicated no significant publication bias in this study.ConclusionsThis meta-analysis indicated that concurrent TP53 mutations was a negative prognostic factor and associated with poorer outcomes of patients with EGFR-TKIs or ALK-TKIs treatments in advanced NSCLC. In addition, our study provided evidence that TP53 mutations might be involved in primary resistance to EGFR-TKIs treatments in patients with sensitive EGFR mutations in advanced NSCLC.

Project description:Ovarian cancer is a deadly malignancy with a growing therapeutic armamentarium, though achieving sustained benefit in the clinic remains largely elusive. Through biomarker and genetic analysis, several pathways of resistance and sensitivity to commonly used therapeutics have been identified, expanding the potential of identifying unique drug combinations and indicating new directions for improving clinical outcomes. Here, we review the mechanisms of angiogenic response and antiangiogenic therapy in ovarian cancer, as well as the interactions it exhibits with the immune and DNA damage response pathways. We discuss results from clinical trials examining the combinations of antiangiogenics, PARP inhibitors, and immune checkpoint inhibitors are also discussed, as well as several ongoing trials.

Project description:Both chemotherapy and epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) are widely applied for the treatment of non-small cell lung cancer (NSCLC), but the efficacy of these two treatments in combination is not yet clear. Thus, we sought to evaluate the efficacy of the intercalated combination of these two treatments in NSCLC. The PubMed database, EMBASE, Cochrane Controlled Trials Register, and Chinese Biomedical Database were systematically searched by two researchers for randomized clinical trials (RCTs) that examined the intercalated combination of chemotherapy and EGFR TKIs in NSCLC. Ten studies involving 1,660 patients were included in this systematic review. The statistical results showed that the intercalated combination of chemotherapy and EGFR TKIs significantly improved overall survival (OS) (hazard ratio (HR)?=?0.83, 95% confidence interval (CI): 0.70-0.98), progression-free survival (PFS) (HR?=?0.65, 95% CI: 0.51-0.84), and the objective response rate (ORR) (risk ratio (RR)?=?1.90, 95% CI: 1.22-2.98) compared to chemotherapy alone. Similarly, compared to EGFR TKIs monotherapy, the intercalated combination of chemotherapy and EGFR TKIs seemed superior to EGFR TKIs alone in terms of PFS, ORR and DCR (PFS: HR?=?0.75, 95% CI: 0.62-0.91, ORR: RR?=?1.49, 95% CI: 1.12-2.00 and DCR: RR?=?1.33, 95% CI: 1.15-1.54) in advanced NSCLC therapy.

Project description:Personalized therapy of advanced non-small cell lung cancer (NSCLC) has been improved by the introduction of EGFR tyrosine kinase inhibitors (TKIs), gefitinib and erlotinib. EGFR TKIs induce dramatic objective responses and increase survival in patients bearing sensitizing mutations in the EGFR intracytoplasmic tyrosine kinase domain. However, virtually all patients develop resistance, and this is responsible for disease relapse. Hence several efforts are being undertaken to understand the mechanisms of resistance in order to develop combination treatments capable to sensitize resistant cells to EGFR TKIs. Recent studies have suggested that upregulation of another member of the EGFR receptor family, namely ErbB3 is involved in drug resistance, through increased phosphorylation of its intracytoplasmic domain and activation of PI3K/AKT signaling. In this paper we first show, by using a set of malignant pleural effusion derived cell cultures (MPEDCC) from patients with lung adenocarcinoma, that surface ErbB3 expression correlates with increased AKT phosphorylation. Antibodies against ErbB3, namely A3, which we previously demonstrated to induce receptor internalization and degradation, inhibit growth and induce apoptosis only in cells overexpressing surface ErbB3. Furthermore, combination of anti-ErbB3 antibodies with EGFR TKIs synergistically affect cell proliferation in vitro, cause cell cycle arrest, up-regulate p21 expression and inhibit tumor growth in mouse xenografts. Importantly, potentiation of gefitinib by anti-ErbB3 antibodies occurs both in de novo and in ab initio resistant cells. Anti-ErbB3 mAbs strongly synergize also with the dual EGFR and HER2 inhibitor lapatinib. Our results suggest that combination treatment with EGFR TKI and antibodies against ErbB3 should be a promising approach to pursue in the clinic.

Project description:Background and objectiveThe therapeutic landscape for non-small cell lung cancer (NSCLC) has evolved considerably in the last few years. The targeted drugs and molecular diagnostics have been developed together at a fast pace. This narrative review explores the evolution of anaplastic lymphoma kinase (ALK) targeting therapies from discovering the ALK protein, molecular tests, present clinical trial data and future perspectives. Since the body of evidence on lung cancer is growing daily, most oncologists need time to implement data in their daily practice.MethodsWe developed a narrative review to provide up-to-date help in the clinical decision-making of ALK-altered NSCLC patients. In 2022, the authors reviewed PubMed's published pivotal randomized Phase 3 trial results.Key content and findingsThe development of ALK inhibitors was a revolution that is still ongoing; second and third-generation ALK inhibitors provided more than 30 months of progression-free survival (PFS) and impressive "brain-control". Brigatinib provided a survival benefit for patients with baseline brain metastases (HR 0.43, 95% CI: 0.21-0.89), and Lorlatinib demonstrated intracranial response rates of 82%, with 71% of complete intracranial responses. Personalized medicine is the new paradigm, from performing broad genetic panels for diagnosis to individual targeted therapy or combinations of different targeted agents.ConclusionsIn the future, performing broad molecular panels should be the standard of care in the front line and after each progression to detect arising resistance mechanisms. Longer PFS will substantially convert a deadly condition into an almost chronic disease in the following decades. Treatment sequencing will be the cornerstone for patient survival, and liquid biopsies may replace tissue biopsies.

Project description:BackgroundThe treatment strategy for brain metastasis (BM) in patients with epidermal growth factor receptor (EGFR) -mutant lung adenocarcinoma (LAC) remains controversial. In the present study, we compared the efficacy of brain radiotherapy (RT) in combination with tyrosine kinase inhibitors (TKIs) and TKIs alone for advanced LAC patients with EGFR mutations and BM.MethodsWe retrospectively studied 78 patients diagnosed with EGFR-mutant LAC who developed BM. These patients were divided into two groups: 49 patients in the combination treatment group who received brain RT in combination with EGFR-TKIs (including 23 patients with asymptomatic BM before RT); 29 patients in the TKI group who received EGFR-TKI targeted therapy alone (including 22 patients with asymptomatic BM before TKI treatment).ResultsThe median intracranial progression-free survival (iPFS) of the combination treatment group was longer than that of the TKI alone group (21.5 vs. 15 months; P = 0.036). However, there were no significant differences in median progression-free survival (PFS, 12 vs. 13 months; P = 0.242) and median overall survival (mOS, 36 vs. 23 months; P = 0.363) between the two groups. Further analysis of asymptomatic BM showed that both the median iPFS and the mOS of the combination treatment group were significantly longer than for the TKI alone group (iPFS, 21.5 vs. 14.8 months, P = 0.026; mOS, 36 vs. 23 months, P = 0.041). Cox multivariate regression analysis found no independent adverse predictors of iPFS in all patients.ConclusionsThe synchronous combination of brain RT and TKIs was superior to EGFR-TKIs alone for EGFR-mutant LAC patients with BM. The combination treatment group exhibited longer iPFS, while the PFS and OS were not significantly different between the two groups. In addition, the combination treatment could result in better iPFS and OS in those with asymptomatic BM. Therefore, addition of brain RT was useful for intracranial metastatic lesions.

Project description:IntroductionThe epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) in combination with anti-vascular endothelial growth factor receptor (VEGFR) agents have shown improved survival outcomes in recent studies. However, its efficacy related to survival outcomes as a first- or second-line agent and based on generations remains to be explored. This study estimated the survival outcomes of EGFR-TKIs plus anti-VEGFR in combination in defined populations of advanced non-small cell lung cancer (NSCLC) patients overall, as a first- or second line of treatment, with different generations of EGFR-TKIs and EGFR-TKIs plus bevacizumab combination as a subgroup.MethodsA literature search was conducted using PubMed, SCOPUS, Cochrane Library, and ClinicalTrials.gov databases through June 2023 to identify primary research reporting the survival outcomes of EGFR-TKIs in combination with anti-VEGFR agents in patients with advanced NSCLC. Studies that were single-arm, published in non-English languages, and had missing data on survival outcomes were excluded. A meta-analysis was conducted to generate pooled hazard ratios (HRs) with 95% confidence intervals (CI) for overall survival (OS) and progression-free survival (PFS). Methodological quality and risk of bias in studies were assessed using the Cochrane Handbook for Systematic Reviews of Interventions risk of bias tool.ResultsA total of 20 randomized controlled trials were included in the qualitative synthesis, and 11 (2182 participants) were included in the meta-analysis. Patients' median age ranged from 58 to 68 years; 36% to 70% of patients were female; most of them had IIIa/b to IV stage cancer. In meta-analyses, the EGFR-TKIs plus anti-VEGFR combination resulted in improved PFS (HR, 0.73; 95% CI: 0.61, 0.86; p < 0.00001) in patients with advanced NSCLC but had no impact on OS (HR, 0.93; 95% CI: 0.79, 1.10; p = 0.41). The first line of treatment and first-generation EGFR-TKIs with the combination also improved the PFS (HR, 0.64; 95% CI: 0.57, 0.71; p < 0.00001; HR, 0.63; 95% CI: 0.56, 0.71; p < 0.00001) respectively, however, had no impact on OS.ConclusionsOur meta-analysis indicated EGFR-TKIs with anti-VEGFR in combination not only improved overall PFS but also showed similar results to a first line and first-generation agent compared to EGFR-TKI alone.

Project description:Lung cancer is the most common cancer and the leading cause of cancer death. Non-small cell lung cancer (NSCLC) represents over 85% of all lung cancers, and up to 50% of Asian NSCLC patients harboring epidermal growth factor receptor (EGFR) gene mutations. A number of studies have consistently demonstrated that uncommon EGFR-mutated NSCLC patients treated with EGFR-tyrosine kinase inhibitors (EGFR-TKIs) can achieve better survival outcomes. However, because uncommon EGFR mutations are generally associated with reduced sensitivity to EGFR-TKIs, which will bring a negative impact on the result of the study, the majority of clinical trials investigating the efficacy of EGFR-TKIs have included only patients with common EGFR mutations. In addition, uncommon EGFR mutations are rare in themselves, leading to the small number of such patients enrolled in these trials. Due to the small number and highly heterogeneous sensitivity of uncommon EGFR mutations, the efficacy of EGFR-TKIs in patients harboring uncommon EGFR mutations remains elusive. This article reviews the efficacy of EGFR-TKIs in patients with uncommon EGFR mutations, and give some reasonable advice about the selection of treatments for patients with NSCLC who harbor uncommon EGFR mutations.

Project description:Despite improvements in cancer therapies in the past 50 years, neuroblastoma remains a devastating clinical problem and a leading cause of childhood cancer deaths. Advances in treatments for children with high-risk neuroblastoma have, until recently, involved addition of cytotoxic therapy to dose-intensive regimens. In this era of targeted therapies, substantial efforts have been made to identify optimal targets for different types of cancer. The discovery of hereditary and somatic activating mutations in the oncogene ALK has now placed neuroblastoma among other cancers, such as melanoma and non-small-cell lung cancer (NSCLC), which benefit from therapies with oncogene-specific small-molecule tyrosine kinase inhibitors. Crizotinib, a small-molecule inhibitor of ALK, has transformed the landscape for the treatment of NSCLC harbouring ALK translocations and has demonstrated activity in preclinical models of ALK-driven neuroblastomas. However, inhibition of mutated ALK is complex when compared with translocated ALK and remains a therapeutic challenge. This Review discusses the biology of ALK in the development of neuroblastoma, preclinical and clinical progress with the use of ALK inhibitors and immunotherapy, challenges associated with resistance to such therapies and the steps being taken to overcome some of these hurdles.
