Progress in treatment of small-cell lung cancer: role of CPT-11.

ABSTRACT: Small-cell lung cancer (SCLC) accounts for approximately 15% of all cases of lung cancer and is a particularly aggressive form of lung cancer characterised by a poor prognosis, rapid tumour growth, and early metastasis. Roughly, two-thirds of patients with SCLC present with extensive disease (ED) and one-third with limited disease (LD). Combination chemotherapy is the most effective treatment modality for SCLC, and several new agents, including carboplatin, ifosfamide, taxans, and topotecan, have been demonstrated to be active; however, there are no data on the survival benefit of these drugs. A CPT-11+ cisplatin regimen has shown improvement in overall survival over the global gold standard regimen, etoposide + cisplatin (Japanese Clinical Oncology Group: JCOG 9511), and three confirmatory randomised controlled trials are in progress to determine the reproducibility of the JCOG 9511 study. JCOG is evaluating the role of CPT-11 and a new triplet regimen containing CPT-11 in limited-stage SCLC. Strategies and the current protocols of the JCOG are presented and discussed. In the future, it will be essential to evaluate molecular target-based drugs for LD and ED SCLC with new standard combination chemotherapy regimens that include CPT-11.

Research progress in the treatment of small cell lung cancer.

Project description:Small cell lung cancer (SCLC) accounts for approximately 10-15% of all lung cancers. No significant improvement has been made for patients with SCLC in the past several decades. The main progresses were the thoracic radiation and prophylactic cranial irradiation (PCI) that improved the patient survival rate. For patients with limited disease and good performance status (PS), concurrent chemoradiotherapy (CCRT) followed by PCI should be considered. For extensive disease, the combination of etoposide and platinum-based chemotherapy remains the standard treatment and consolidative thoracic radiotherapy is beneficial for patients who have a significant respond to initial chemotherapy. However, the prognosis still remains poor. Recently, efforts have been focused on molecular targets and immunotherapy. But numerous molecular targets methods have failed to show a significant clinical benefit in patients with SCLC. It is anticipated that further development of research will depend on the on-going trials for molecular targeted therapy and immunotherapy which are promising and may improve the outcomes for SCLC in the next decade.

[Progress in Role of FEZF1-AS1 in Non-small Cell Lung Cancer].

Project description:Nowadays, accumulating evidence indicates that long non-coding RNA (lncRNA) play vital roles in tumorigenesis. As a newly discovered lncRNA, FEZ family zinc finger 1-antisense RNA 1 (FEZF1-AS1) is markedly upregulated in various malignant tumors including non-small cell lung cancer (NSCLC). Aberrant expression of FEZF1-AS1 is related to clinical characteristics of patients with NSCLC and suggests poor prognosis. Moreover, FEZF1-AS1 can regulate numerous biological processes, such as cell proliferation, migration and invasion through different mechanisms. In this article, we systematically summarize the recent research progress of FEZF1-AS1 in NSCLC, which might be a novel target for clinical therapy.

Progress in immunotherapy for small cell lung cancer.

Project description:Small-cell lung cancer (SCLC) is a special type of lung cancer that belongs to highly aggressive neuroendocrine tumors. At present, radiotherapy and chemotherapy remain the mainstay of treatment for SCLC. Progress in targeted therapies for SCLC with driver mutations has been slow, and these therapies are still under investigation in preclinical or early-phase clinical trials, and research on antiangiogenic tyrosine kinase inhibitors (e.g., anlotinib) has achieved some success. Immunotherapy is becoming an important treatment strategy for SCLC after radiotherapy and chemotherapy. In this article we review the recent advances in immunotherapy for SCLC.

[Clinical Progress in the Immunotherapy of Small Cell Lung Cancer].

Project description:Small cell lung cancer is a kind of malignant tumor with strong invasiveness and poor prognosis, and the classic therapeutic modality of the disease remains multidisciplinary and comprehensive treatment. Treatment options for small cell lung cancer have been stalled for a long time, and new opportunities have emerged in recent years due to the development and initial experience of immunotherapeutic drugs. Clinical trials of some selected immune checkpoint inhibitors have confirmed the efficacy and safety in small cell lung cancer. Based on the results of phase III clinical trials (Impower133 and CASPIAN), Atezolizumab or Durvalumab in combination with chemotherapy has been approved by the U.S. Food and Drug Administration for the first-line treatment of extensive-stage small cell lung cancer. Clinical trials involving immune checkpoint inhibitors are being actively carried out and provide different perspectives for the management of small cell lung cancer. This article aimed to review the clinical progress in immunotherapy of small cell lung cancer. .

[Research Progress of the Role of EMT in EGFR-TKIs Resistance ?of Non-small Cell Lung Cancer].

Project description:Lung cancer is the one of the malignant tumor of the highest morbidity and mortality over the world, and non-small cell lung cancer (NSCLC) makes up about 80%. Nowadays, molecular targeted therapy has been the first-line treatment for NSCLC. Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are increasingly used in the clinical treatment, but the EGFR-TKIs acquired resistance becomes the bottleneck of continuation of EGFR-TKIs therapy. Epithelial-mesenchymal transition (EMT) is a biological phenomenon in which epithelial cells are transformed into mesenchymal cells. EMT promoted metastasis, invasion of lung cancer and conferred characteristic of stem cell on cancer cells. Meanwhile, EMT is one of an important cause of EGFR-TKIs resistance in NSCLC. The recent studies have found that resistant cells restored the sensitivity to EGFR-TKIs by reversing EMT which suggested that the target of EMT may contribute to inhibit or even reverse the resistance of EGFR-TKIs. Here we make a review about research progress of EMT in EGFR-TKIs resistance in NSCLC.?.

[Research Progress of KRAS Mutation in Non-small Cell Lung Cancer].

Project description:Lung cancer is the leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) accounts for 80%-85% of all patients with lung cancer, the majority of patients with lung cancer at the time of diagnosis is in the advanced stage. The development of target therapy based on has changed the mode of treatment in patients with advanced NSCLC. In NSCLC, epidermal growth factor receptor mutation (EGFR) fusion with echinoderm microtubule-associated protein-like4-anaplastic lymphoma kinase (EML4-ALK) has been shown to be a powerful biomarker. It is well known that KRAS is also NSCLC one of the most common mutations in oncogenes, although more than 20 years ago KRAS mutation was found in NSCLC. At present, although there are many drugs used to treat NSCLC patients with KRAS mutation, there is no selective or specific inhibitor for the direct elimination of KRAS activity. NSCLC patients with KRAS mutation have poor responsiveness to most systemic therapy. However, individualized therapy for activated signaling pathways with targeted drugs has a good effect on the prognosis of NSCLC patients with KRAS mutation. In addition, the prognostic and predictive role of KRAS mutation in NSCLC remains unclear. In this review, we focus on the research progress of NSCLC with KRAS mutation, including molecular biology, clinicopathological features, prognosis and prediction of KRAS mutation, which will help to improve the understanding of NSCLC in KRAS mutation.?.

Small cell lung cancer: will recent progress lead to improved outcomes?

Project description:Small cell lung cancer (SCLC) is an aggressive neuroendocrine malignancy with a unique natural history characterized by a short doubling time, high growth fraction, and early development of widespread metastases. Although a chemotherapy- and radiation-sensitive disease, SCLC typically recurs rapidly after primary treatment, with only 6% of patients surviving 5 years from diagnosis. This disease has been notable for the absence of major improvements in its treatment: Nearly four decades after the introduction of a platinum-etoposide doublet, therapeutic options have remained virtually unchanged, with correspondingly little improvement in survival rates. Here, we summarize specific barriers and challenges inherent to SCLC research and care that have limited progress in novel therapeutic development to date. We discuss recent progress in basic and translational research, especially in the development of mouse models, which will provide insights into the patterns of metastasis and resistance in SCLC. Opportunities in clinical research aimed at exploiting SCLC biology are reviewed, with an emphasis on ongoing trials. SCLC has been described as a recalcitrant cancer, for which there is an urgent need for accelerated progress. The NCI convened a panel of laboratory and clinical investigators interested in SCLC with a goal of defining consensus recommendations to accelerate progress in the treatment of SCLC, which we summarize here.

[Progress in Neoadjuvant Immunotherapies for Resectable Non-small Cell Lung Cancer].

Project description:Resectable non-small cell lung cancer (NSCLC) is currently considered as a potentially curable disease. Surgery is still the main treatment mode for resectable NSCLC, but quite a few patients will have local recurrence and distant metastasis after surgery. Therefore, preoperative and postoperative adjuvant therapy may be necessary in order to improve the long term outcome. Immunocheckpoint inhibitor has been demonstrated clinically to be effective andapproved as first- or second-line treatment agent in metastatic NSCLC or partially locally advanced NSCLC. The remarkable efficacy of immunotherapy for advanced lung cancer has attracted more and more attention from the researchers to the role of immunotherapy as neoadjuvent therapy in resectable non-small cell lung cancer. This article systematically reviewed the clinical trials of neoadjuvant immunotherapy for resectable NSCLC before surgery.

Current Management and Progress in Radiotherapy for Small Cell Lung Cancer.

Project description:Radiotherapy (RT) and chemotherapy continue to be widely utilized in small cell lung cancer (SCLC) management. In most limited stage (LS)-SCLC cases, the standard initial therapy remains concurrent chemoradiotherapy (CRT), typically with an etoposide and platinum-based regimen. Hyperfractionated twice daily (BID) RT remains the standard of care, though conventional daily (QD) RT is now a viable alternative supported by randomized evidence. In LS-SCLC patients who experienced good response to CRT, prophylactic cranial irradiation (PCI) remains the standard of care. Brain imaging, ideally with MRI, should be performed prior to PCI to screen for clinically apparent brain metastases that may require a higher dose of cranial irradiation. Platinum doublet chemotherapy alone is the historic standard initial therapy in extensive stage (ES)-SCLC. Addition of immunotherapy such as atezolizumab and durvalumab to chemotherapy is now recommended after their benefits were demonstrated in recent trials. In patients with response to chemotherapy, consolidation thoracic RT and PCI could be considered, though with caveats. Emergence of hippocampal avoidance cranial irradiation and SRS in SCLC patients may supplant whole cranial irradiation as future standards of care. Incorporation of novel systemic therapies such as immunotherapies has changed the treatment paradigm and overall outlook of patients with SCLC. This narrative review summarizes the current state, ongoing trials, and future directions of radiotherapy in management of SCLC.

Research Progress on RET Fusion in Non-Small-Cell Lung Cancer.

Project description:Great progress has been made in the treatment of driver gene-positive Non- Small Cell Lung Cancer (NSCLC) in recent years. RET fusion was seen in 0.7% to 2% of NSCLC and was associated with younger age and never-smoker status. The pralsetinib and selpercatinib for RET fusion NSCLC was recommended by the 2021 NSCLC treatment guidelines. This review outlines the research progress in the treatment of RET fusion NSCLC, identifies current challenges and describes proposals for improving the outlook for these patients.
