Non-Small Cell Lung Cancer Treatment with Molecularly Targeted Therapy and Concurrent Radiotherapy—A Review. Int J Mol Sci 2023; 24:ijms24065858. [PMID: 36982933 PMCID: PMC10052930 DOI: 10.3390/ijms24065858] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/13/2023] [Accepted: 03/13/2023] [Indexed: 03/22/2023] Open
Abstract
Lung cancer is the leading cause of death worldwide for both men and women. Surgery can be offered as a radical treatment at stages I and II and selected cases of stage III (III A). Whereas at more advanced stages, combined modalities of treatment are applied: radiochemotherapy (IIIB) and molecularly targeted treatment (small molecule tyrosine kinase inhibitors, VEGF receptor inhibitors, monoclonal antibodies, and immunological treatment with monoclonal antibodies). Combination treatment, composed of radiotherapy and molecular therapy, is increasingly employed in locally advanced and metastatic lung cancer management. Recent studies have indicated a synergistic effect of such treatment and modification of immune response. The combination of immunotherapy and radiotherapy may result in the enhancement of the abscopal effect. Anti-angiogenic therapy, in combination with RT, is associated with high toxicity and should be not recommended. In this paper, the authors discuss the role of molecular treatment and the possibility of its concurrent use with radiotherapy in non-small cell lung cancer (NSCLC).

Abstract
Aim: To assess the efficacy and safety of EGFR inhibitors combined with (chemo)radiotherapy in unresectable, locally advanced non-small-cell lung cancer. Materials & methods: A systematic review and meta-analysis of prospective trials was performed. Results: Twenty-eight studies of 1640 patients were included. In patients harboring EGFR-sensitive mutations, the pooled objective response rate, 1-year overall survival rate and 1-year progression-free survival rate of EGFR-TKIs + (chemo)radiotherapy were 0.803, 0.766 and 0.554, respectively. Compared with chemoradiotherapy, the addition of EGFR inhibitors did not significantly increase the risk of grade ≥3 pneumonitis and esophagitis. Conclusion: EGFR-tyrosine kinase inhibitors combined with (chemo)radiotherapy are tolerable and the clinical benefit is promising, especially in patients with EGFR-sensitive mutations.

EGFR-directed monoclonal antibodies in combination with chemotherapy for treatment of non-small-cell lung cancer: an updated review of clinical trials and new perspectives in biomarkers analysis. Cancer Treat Rev 2018; 72:15-27. [PMID: 30445271 DOI: 10.1016/j.ctrv.2018.08.002] [Citation(s) in RCA: 27] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2017] [Revised: 07/30/2018] [Accepted: 08/03/2018] [Indexed: 02/08/2023]
Abstract
Lung cancer still represents one of the most common and fatal neoplasm, accounting for nearly 30% of all cancer-related deaths. Targeted therapies based on molecular tumor features and programmed death-1 (PD-1)/programmed death ligand-1 (PDL-1) blockade immunotherapy have offered new therapeutic options for patients with advanced non-small-cell lung cancer (NSCLC). Activation of the epidermal growth factor receptor (EGFR)-pathway promotes tumor growth and progression, including angiogenesis, invasion, metastasis and inhibition of apoptosis, providing a strong rationale for targeting this pathway. EGFR expression is detected in up to 85% of NSCLC and has been demonstrated to be associated with poor prognosis. Two approaches for blocking EGFR signaling are available: prevention of ligand binding to the extracellular domain with monoclonal antibodies (mAbs) and inhibition of the intracellular tyrosine kinase activity with small molecules. There is a strong rationale to consider the tumor's level of EGFR expression as one of the most significant predictive biomarkers in this setting. In this paper we provide an update focusing on the current status of EGFR-directed mAbs use for the treatment of patients with advanced NSCLC, through a review of all clinical trials involving anti-EGFR mAbs in combination with chemotherapy (CT) for advanced disease and with chemo-radiotherapy for stage III disease. Here we also discuss the current status of predictive biomarkers for anti-EGFR mAbs when added to first-line CT in patients with advanced NSCLC. Finally, we focused on the relevance of EGFR fluorescence in situ hybridization (FISH)+ and immunohistochemistry (IHC)-Score ≥ 200 as predictive biomarkers for the selection of patients who would be most likely to derive a clinical benefit from treatment with CT in combination with anti-EGFR mAbs, with particular reference also to histology.

Abstract
Effective treatments for non-small cell lung carcinoma (NSCLC) remain elusive. The use of concurrent chemotherapy with radiotherapy (RT) has improved outcomes, but a significant proportion of NSCLC patients are too frail to be able to tolerate an intense course of concurrent chemoradiotherapy. The development of targeted therapies ignited new hope in enhancing radiotherapeutic outcomes. The use of targeted therapies against the epidermal growth factor receptor (EGFR) has offered slight but significant benefits in concurrent use with RT for certain patients in certain situations. However, despite theoretical promise, the use of anti-angiogenics, such as bevacizumab and endostatin, has not proven clinically safe or useful in combination with RT. However, many new targeted agents against new targets are being experimented for combined use with RT. It is hoped that these agents may provide a significant breakthrough in the radiotherapeutic management of NSCLC. The current review provides a brief discussion about the targets, the targeted therapies, the rationale for the use of targeted therapies in combination with RT, and a brief review of the existing data on the subject.

Abstract
OBJECTIVES The modest benefits from concurrent chemoradiotherapy (CCRT) in patients with stage III non-small cell lung cancer (NSCLC) warrant a more effective treatment regimen. We herein report mature data of a phase I/II study testing the addition of cetuximab to induction vinorelbine/cisplatin (NP) followed by concurrent cetuximab NP and thoracic radiation in patients with unresectable stage III NSCLC. MATERIALS AND METHODS Eligible patients were treated with weekly cetuximab (initial dose 400 mg/m2, day 1, week 1; maintenance dose 250 mg/m2 from week 2 to the end of CCRT) and induction vinorelbine (25 mg/m2, days 1 and 8) and cisplatin (75 mg/m2, day 1) every 3 weeks for 2 cycles from week 2. Concomitant thoracic radiation (60-66 Gy/2 Gy) and two cycles of NP (vinorelbine 12.5 mg/m2, days 1 and 8; cisplatin 25mg/m2, days 1 to 3, every 3 weeks) were started from week 7. The primary endpoints were toxicities; the secondary endpoints encompassed response rate and survival. RESULTS In total, 27 patients were enrolled, and 24 completed the full regimen. No treatment-related death occurred. Severe (CTCAE Grade 3 or high) adverse events were experienced by 81% patients (22/27), mostly haematologic. Severe non-haematologic toxicities including nausea/vomiting, intestinal obstruction, pulmonary infection and esophagitis, each of which was detected in <7% of patients. With a median follow-up of 26.7 months, the median survival was 26.7 months, with 1- and 2-year survival rates of 88.9% and 51.9%, respectively. Six patients remained progression-free to date, and the median progression-free survival was 13.5 months. The overall response rate was 63% and 77.8% after the induction and CCRT phases, respectively. CONCLUSION Weekly cetuximab with induction vinorelbine/cisplatin followed by concurrent cetuximab vinorelbine/cisplatin thoracic radiation is feasible with a manageable toxicity profile and clinically active.

Abstract
OBJECTIVE In recent years, the combination of cetuximab and chemoradiotherapy (CRT) has been used to treat stage III non-small cell lung cancer (NSCLC); however, limited data are available for Chinese patients. Herein, we report preliminary data from a phase I/II study testing the combination of cetuximab with inductive chemotherapy, followed by concurrent CRT (CCRT) in Chinese patients with stage III NSCLC. METHODS Eligibility criteria were Zubrod performance status (PS) 0-1, forced expiratory volume in 1 second (FEV1) ≥1.2 L and adequate organ function. Enrolled patients received weekly cetuximab (initial dose of 400 mg/m(2) on day 1 of week 1 and a maintenance dose of 250 mg/m(2) on week 2 to the end of CCRT) with cisplatin/vinorelbine (NP) chemotherapy (every 3 weeks for 2 cycles from week 2, followed by two cycles of concomitant NP chemotherapy and intensity-modulated thoracic radiotherapy (TRT) (60-66 Gy/2 Gy). The primary endpoints were toxicity and feasibility. All patients received positron emission tomography-computerized tomography (PET-CT) scans within the 2 weeks prior to enrollment. Univariate analyses were used to assess the correlation between SUV-T, SUV-N, SUV-TOTAL, gender, age, histology, tumor-node-metastasis (TNM) stage, PS and smoking status and survival. Survival curves were generated for different populations using the Kaplan-Meier method and compared using a log-rank test. RESULTS Seventeen patients were enrolled and 16 completed the full regime. The overall response rate (ORR) was 58.8% and 82.3% after the induction and CCRT phases, respectively. With a median follow-up duration of 27.6 months, the median survival was 27.6 months [95% confidence interval (CI): 11.3-43.9 months] with 1- and 2-year survival rates of 88.2% (95% CI, 60.6-96.9%) and 58.8% (95% CI, 60.6-77.8%), respectively. Three patients remain progression-free to date, and the median progression-free survival (PFS) was 13.5 months (95% CI, 6.8-20.2 months). No treatment-related death occurred; however, 76% of the patients experienced grade 3+ adverse events (AEs), including nausea/vomiting, intestinal obstruction, and esophagitis (<6%), while other AEs were mostly of hematological nature (71%). The cut-off values for SUV-T and SUV-TOTAL were 11 and 20, respectively. Univariate analyses revealed SUV-TOTAL (P=0.027), SUV-T (P=0.025), and PS (P=0.006) as potential survival predictors, with a hazard ratio (HR) of 3.4, 3.7, and 9.9, respectively. CONCLUSIONS The combination of cetuximab with induction chemotherapy followed by CCRT appears feasible and promising. Local and locoregional maximal SUVs, defined by (18)F-FDG PET-CT scanning, may represent a prognostic indicator for long-term survival for these patients, which warrants further study.

Abstract
BACKGROUND There is no consensus on the therapeutic approach to poor-risk patients with unresectable stage III non-small-cell lung cancer (NSCLC), despite the increasing number of these patients in current clinical practice. In terms of survival, the combination of concurrent systemic therapy with standard radiotherapy might be advantageous over radiotherapy alone. The purpose of this review is to ascertain the feasibility, safety and efficacy of the combination of concurrent systemic therapy and standard radiotherapy in these patients. METHODS A computer-based literature search was carried out using PubMed and Science Direct for relevant publications; data reported at major conferences in abstract form were also included. RESULTS In unresectable stage III NSCLC, advanced age, poor performance status, weight loss and comorbidities are factors that influence treatment options and disease outcomes in clinical practice. Prospective studies including poor-risk patients have been reviewed. Trials specifically recruiting poor-risk patients have been separated into those using chemotherapy and those using targeted agents with or without chemotherapy. Only two phase III studies specifically including poor-risk patients have been published. Some recent studies suggested that tolerable radio-sensitizing therapy combined with radiotherapy can provide longer survival outcomes than those reported earlier with chemo-radiotherapy or with radiotherapy alone. CONCLUSIONS There is an unmet need to develop well-designed clinical trials with tolerable combinations of systemic therapy and radiotherapy specifically tailored to this lung cancer population. Such trials should incorporate careful comorbidity measurement and, in older adults, a validated geriatric assessment.

Abstract
Treatment of inoperable, locally advanced non-small cell lung cancer (LA-NSCLC) is challenging and requires a multidisciplinary approach considering both local therapy and systemic therapy. Based on the results from several phase III studies and 2 meta-analyses, the use of concomitant chemoradiation therapy (ChRT) could significantly improve overall survival and is considered the standard of care in LA-NSCLC with good performance status. Currently, no evidence has shown a significant survival benefit of third-generation regimens applied in combination with ChRT compared with second-generation regimens. For regimens concomitant with radiation therapy, full-dose chemotherapy (such as cisplatin and etoposide or cisplatin and vinblastine) might be preferred. Additional full-dose consolidation paclitaxel-carboplatin is recommended when patients receive weekly paclitaxel-carboplatin ChRT. Effective novel chemotherapy agents or targeted therapies are required to further improve the outcome of patients with LA-NSCLC. In addition, personalized medicine concomitant with radiation therapy is a promising approach. However, little evidence exists concerning the effectiveness of this novel approach.

Abstract
PURPOSE We investigated whether expression of epidermal growth factor receptor (EGFR) was associated with survival and disease control in this secondary analysis of a phase II trial of cetuximab+chemoradiation for stage III non-small cell lung cancer. METHODS Patients received cetuximab weekly before and during radiation (63 Gy/35 fractions/7 weeks) with weekly carboplatin + paclitaxel. We analyzed EGFR expression by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in pretreatment biopsy specimens and compared findings with overall and progression-free survival (OS, PFS) and time to progression (TTP). RESULTS Specimens for IHC and FISH were collected from 51 and 45 of 87 evaluable patients. Pretreatment characteristics did not differ for patients with (n = 51) or without (n= 36) EGFR IHC data, or with (n = 45) or without (n = 42) FISH data. However, patients without IHC data had worse OS (HR = 1.63, P = 0.05), worse PFS (HR = 1.88, P = 0.008), and worse TTP [HR = 1.99, P = 0.01] than those with IHC data. EGFR protein expression was not related to pretreatment characteristics or OS; FISH-positive disease was associated with better performance status but not with OS, PFS, or TTP. CONCLUSIONS Surprisingly, outcomes differed not by EGFR expression but by the availability of samples for analysis, underscoring the importance of obtaining biopsy samples in such trials.
