Purpose: To investigate the feasibility and activity of concurrent radiochemotherapy in patients with Stage III nonsmall-cell lung cancer (NSCLC). Materials and Methods: Forty-one patients were treated with hyperfractionated radiation therapy (HfxRT) using 1.2 Gy bid, to a total of 69.6 Gy and concurrent low-dose daily chemotherapy (CHT) consisting of 30 mg of carboplatin (CBDCA) and 30 mg of etoposide (VP-16) given Mondays to Fridays during the RT course. On Saturdays and Sundays during the RT course, CBDCA and VP-16 were both given in a daily dose of 100 mg each. Results: Median survival time was 25 months, and 3- and 5-year survival rates were 34% and 29%, respectively. Median relapse-free survival time was 22 months, and 3- and 5-year relapse-free survival rates were 32%, and 29%, respectively. Median time to local recurrence was 24 months and 3- and 5-year local recurrence-free survival rates were 41% and 38%, respectively. Median time to distant metastasis was 28 months, and 3- and 5- year distant metastasis-free survival rates were 44% and 44%, respectively. Acute high-grade (≥ 3) toxicity was mostly hematological (30%), esophageal (15%), and bronchopulmonary (12%). Late high-grade toxicity was infrequent. Conclusion: This combined radiochemotherapy regimen produced promising results and warrants further studies with more patients before testing it in a prospective randomized fashion. 相似文献

The emergence of immunotherapy has dramatically changed how non–small cell lung cancer is treated, and longer survival is now possible for some patients, even those with advanced disease. Although some patients achieve durable responses to checkpoint blockade, not all experience such benefits, and some suffer from significant immunotoxicities. Given this, biomarkers that predict response to therapy are essential, and testing for tumor programmed death ligand 1(PD-L1) expression is the current standard. The extent of PD-L1 expression determined by immunohistochemistry (IHC) has demonstrated a correlation with treatment response, although limitations with this marker exist. Recently, tumor mutational burden has emerged as an alternative biomarker, and studies have demonstrated its utility, irrespective of the PD-L1 level of a tumor. Gene expression signatures, tumor genotype (such as the presence of an oncogenic driver mutation), as well as the density of tumor-infiltrating lymphocytes in the tumor microenvironment also seem to affect response to immunotherapy and are being researched. Peripheral serum markers are being studied, and some have demonstrated predictive ability, although most are still investigational and need prospective validation. In the current article, the authors review the biomarker PD-L1 as well as other emerging and investigational tissue-based and serum-based markers that have potential to better predict responders to immunotherapy. 相似文献

The discovery of Epidermal Growth Factor Receptor (EGFR) mutations in Non Small Cell Lung Cancer (NSCLC) launched the era of personalized medicine in advanced NSCLC, leading to a dramatic shift in the therapeutic landscape of this disease. After ten years from the individuation of activating mutations in the tyrosine kinase domain of the EGFR in NSCLC patients responding to the EGFR tyrosine kinase inhibitor (TKI) Gefitinib, several progresses have been done and first line treatment with EGFR TKIs is a firmly established option in advanced EGFR-mutated NSCLC patients. During the last decade, different EGFR TKIs have been developed and three inhibitors have been approved so far in these selected patients. However, despite great breakthroughs have been made, treatment of these molecularly selected patients poses novel therapeutic challenges, such as emerging of acquired resistance, brain metastases development or the need to translate these treatments in earlier clinical settings, such as adjuvant therapy.The aim of this paper is to provide a comprehensive review of the major progresses reported so far in the EGFR inhibition in this molecularly-selected subgroup of NSCLC patients, from the early successes with first generation EGFR TKIs, Erlotinib and Gefitinib, to the novel irreversible and mutant-selective inhibitors and ultimately the emerging challenges that we, in the next future, are called to deal with. 相似文献

Lung cancer, is the most common cause of cancer death in men and second only to breast cancer in women. Currently, the first line therapy of choice is platinum-based combination chemotherapy. A therapeutic plateau has been reached with the prognosis for patients with advanced non-small cell lung cancer (NSCLC) remaining poor. New biomarkers of prognosis as well as new therapies focusing on molecular targets are emerging helping to identify patients who are likely to benefit from therapy. Despite this, drug resistance remains the major cause for treatment failure. In this article we review the role of apoptosis in mediating drug resistance in NSCLC. Better understanding of this fundamental biological process may provide a rationale for overcoming the current therapeutic plateau. 相似文献

Purpose The present article reports the results of a multicentre phase II study analysing both activity and tolerance of the cisplatin vinorelbine combination in patients with inoperable NSCLC. Materials and methods 87 consecutive patients from 6 Institutions were treated with vinorelbine 25 mg/m 2 on days 1 and 8, plus cisplatin 100 mg/m 2 on day 1, both intravenously, every 21 days. All patients were younger 75 years old, with unresectable non small cell lung cancer stages IIIA, IIIB and IV, who had a measurable or assessable disease, performance status ECOG 0–2 and had more than 12 weeks life expectancy. Response was assessed after 3 courses. Toxicity was assessed after every cycle. Results 87 patients treated, all them were evaluable for response. Five patients (5.7%) had a complete response and twenty-two (25.3%) a partial one. The median overall survival was 8.03 months. The toxicity, evaluated on 262 cycles administered, was mainly haematological: 11,3% of courses grade 3–4 neutropenias and 3,8% grade 3 thrombocytopenias. There were 4 deaths due to toxicity (4.5%). Discussion The vinorelbine-cisplatin is active with manageable toxicity and response rates are in the range of results usually reported in the previous studies evaluating this combination. It suggest that this combination should be considered as a reference regimen in patients with advanced NSCLC. 相似文献

Sequential hemibody irradiation (SHB) was integrated with combination chemotherapy and local irradiation (LRT) in the induction and consolidation phases of a therapeutic protocol for small cell lung carcinoma (SCLC). Forty-one previously untreated patients were entered into this program. Among 38 evaluable patients (20 with limited disease [LD] and 18 with extensive disease [ED], the overall response rate was 63% (90% in LD and 33% in ED patients). The estimated overall survival is 8.1 months. The major toxicity has been myelosuppression--especially thrombocytopenia. The frequency of previously described "acute radiation syndromes" and radiation pneumonitis associated with hemibody irradiation have been substantially decreased at the current dosage with premedication and shielding techniques. The integration of SHB as a systemic therapy with combination chemotherapy and LRT is a feasible program for sequential administration of non-cross-resistant agents in SCLC and may be beneficial in patients with limited disease. 相似文献
