Treatment of locally advanced non-small cell lung cancer with combination of chemotherapy and radiation

The treatment of locally advanced non-small cell lung cancer has improved substantially over the past 20 years. Almost three times as many patients are able to achieve long-term survival today compared with the mid-1980s. This improvement has been possible through the cooperation of physicians from different specialties involved in the care of lung cancer patients. More accurate staging, with the use of positron emission tomography, led to more accurate stage classification. Patients with detectable systemic disease can be spared from an aggressive local therapy whereas patients with small volume, stage IIIB, can receive the most appropriate treatment. Clinical trials in the United States and around the world have identified the role of each treatment modality and the appropriate timing of administration. The present standard of care is the concurrent administration of cisplatin-based chemotherapy and radiotherapy. This is a treatment that can be associated with significant morbidity, and patient selection is paramount. Chronological age, by itself, should not be a reason to deny a patient the most appropriate treatment for lung cancer. The presence of comorbidities, on the other hand, is a key factor in deciding the most appropriate treatment. When the concurrent administration of chemo- and radiotherapy is not appropriate, the sequential delivery of these two modalities is superior to each of them given alone. Over the last 6 months, two trials have shown that erlotinib (an epidermal growth factor receptor inhibitor) and bevacizumab (a vascular endothelial growth factor inhibitor) improve survival in non-small cell lung cancer patients. These findings represent a landmark in the care of lung cancer patients. We are entering an era of improved patient identification and more logical therapeutic approaches. The incorporation of these "targeted therapies" in the treatment of patients with locally advanced disease is being actively investigated and will, it is hoped, translate into significant therapeutic benefits for the patients.     

Sequential combination chemotherapy and radiotherapy in locally advanced non-small cell carcinoma of the bronchus

The feasibility, effectiveness and toxicity of a new four drug intensive combination chemotherapy regime has been assessed in 36 patients with inoperable non-small cell lung cancer. Three cycles of adriamycin, vindesine, ifosfamide and cisplatin were given to 36 patients followed by sequential radiotherapy to 25 patients. The overall response rate to chemotherapy was 33%, and median progression free interval was 6 months. Median survival was 8.5 months. Grade 4 WHO neutropenia was seen in 12 patients, there were three episodes of neutropenic fever and one death in which toxicity may have been contributory. Radiotherapy was not associated with serious toxicity. This study demonstrates that a significant response rate can be achieved with short intensive chemotherapy in unresectable non-small cell lung cancer and that it is feasible to combine this with radiotherapy.     

苦参碱联合化疗对晚期非小细胞肺癌的疗效观察

Concurrent cisplatin and etoposide with radiotherapy in locally advanced non-small cell lung cancer

Twenty consecutive patients with newly diagnosed or locally recurrent non-small cell lung cancer limited to the chest were treated with concurrent radiotherapy and cisplatin plus etoposide. No patient had received prior chemotherapy or radiotherapy. Sixteen of 20 patients (80%) responded to the treatment. Median survival has not been reached but is greater than 13.5 months. Twelve patients have relapsed at a median of 10 months after starting therapy (range, 4-12 months), with only one initial relapse within the radiotherapy port. Hematologic toxicity was mild, with four of 52 wbc count nadirs less than 1000/mm3. Esophageal toxicity was also mild, with all patients maintaining oral intake throughout therapy. We conclude that simultaneous radiotherapy, cisplatin, and etoposide can be safely administered in locoregional non-small cell carcinoma of the lung. A prospective trial of this regimen versus radiotherapy alone is warranted.     

The role of palliative radiotherapy in locally advanced non-small cell lung cancer

The aim of this study was to evaluate retrospectively the treatment results of non-small cell lung cancer (NSCLC) patients treated with palliative intent in Dokuz Eylul University Hospital, Radiation Oncology Department. One hundred and fifteen inoperable, non-metastatic and symptomatic NSCLC patients were treated with palliative radiotherapy (PRT) between July 1991 and May 2000. PRT was used in patients with low performance status, weight loss more than 10% within last 6 months, secondary malignancies, co-morbid diseases and socio-economic problems. Parallelly opposed isocentric antero-posterior fields including both the parenchymal and mediastinal masses were used. 10-55 Gy total doses were delivered in 1-23 fractions with a median of 30 Gy. Nineteen patients received systemic chemotherapy before PRT. Survival analysis was made from the treatment beginning date, and subjective palliation rates were assessed according to clinical improvements in symptomatology evaluated 1-6 weeks after PRT. The median follow-up time was 28 weeks (1-234 weeks). Totally, 245 disease-related symptoms were detected in 115 patients. Overall "improvement" in symptomatology was found to be 90% (221/245) with a "near-total response" rate of 46% (113/245). Hemoptysis was the best palliated symptom. Median survival time was 30 weeks. Karnofsky performance status (KPS) (p=0.015), weight loss (p=0.0015), histologic tumor type (p=0.0024) and tumor size (p=0.02) were found to effect overall survival rates significantly in uni-variant analysis. Multi-variant analysis revealed statistically significant effect with histological tumor type and weight loss status. Only 16% of patients (3/19) showed partial and 5% (1/19) complete response to systemic treatment. Median survival time was 46 weeks in this group. In conclusion, this retrospective study of patients with poor prognostic factors confirms that PRT is an effective treatment modality in symptomatic locally advanced NSCLC patients resulting in 90% symptomatic improvement rate and a median survival of 30 weeks.

Sequential or concomitant chemotherapy with hypofractionated radiotherapy for locally advanced non-small cell lung cancer: a meta-analysis of randomized trials

BackgroundFor patients with locally advanced non-small cell lung cancer (NSCLC), the standard treatment is concurrent or sequential chemotherapy with radiotherapy. Most treatment schedules use radiotherapy with conventional fractionation; however, the application of hypofractionated radiotherapy (HYPO-RT) regimens is rising. A meta-analysis was performed to assess the efficacy and safety of chemotherapy combined with HYPO-RT and indirectly compare with the outcomes from previous studies employing concomitant conventional radiotherapy (CONV-RT).MethodsRandomized controlled trials (RCTs) were identified on the electronic database sources through June 2020. Following the PRISMA guidelines, a meta-analysis was performed to assess if there were significant differences in the overall mortality (OM), local failure (LF), and disease progression (DP), comparing HYPO-RT-C vs. sequential chemotherapy followed HYPO-RT (HYPO-RT-S). To establish an indirect comparison with the current standard treatment, we calculate the risk ratio (RR) of the OM from RCTs using conventional chemoradiation, concurrent (CONV-RT-C), and sequential (CONV-RT-S), and compared with HYPO-RT. A P value <0.05 was considered significant.ResultsTwo RCTs with a total of 288 patients were included. The RR for the OM, DP and LF at 3 year comparing HYPO-RT-C vs. HYPO-RT-S were 1.09 (95% CI: 0.96–1.28, P=0.17), 1.06 (95% CI: 0.82–1.23, P=0.610), and 1.06 (95% CI: 0.86–1.29, P=0.490), respectively. The late grade 3 pneumonitis and esophagitis had no significant difference between HYPO-RT groups. In the indirect comparison of RCTs using CONV-RT, the RR for the OM at 3 years was 1.03 (95% CI: 0.96–1.10, P=0.36) with no significant difference for the HYPO-RT arms 1.09 (95% CI: 0.96–1.28, P=0.17).DiscussionHYPO-RT given with chemotherapy provides satisfactory OM, LF, and DP in locally advanced NSCLC with similar rates to the CONV-RT. These findings support HYPO-RT inclusion in future clinical trials as an experimental arm in addition to the incorporation of new strategies, such as immunotherapy.
