Clinical Outcome of Nivolumab Plus Ipilimumab in Patients with Locally Advanced Non-Small-Cell Lung Cancer with Relapse after Concurrent Chemoradiotherapy followed by Durvalumab. Cancers (Basel) 2024; 16:1409. [PMID: 38611087 PMCID: PMC11011053 DOI: 10.3390/cancers16071409] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2024] [Revised: 04/01/2024] [Accepted: 04/02/2024] [Indexed: 04/14/2024] Open
Abstract
Nivolumab plus ipilimumab showed promising efficacy in patients with metastatic non-small-cell lung cancer (NSCLC). The efficacy of the nivolumab plus ipilimumab combination regimen in NSCLC patients who relapse after durvalumab consolidation following concurrent chemoradiotherapy (CCRT) has not been determined. Between January 2021 and June 2022, clinical data were retrospectively extracted from the medical records of patients with NSCLC who received nivolumab plus ipilimumab after CCRT and durvalumab consolidation. A total of 30 patients were included in this analysis. The median number of durvalumab treatment cycles was 11. Median PFS and OS with nivolumab plus ipilimumab were 4.2 months (95% confidence interval [CI]: 0.7-7.7) and 18.5 months (95% CI: 3.5-33.5), respectively. The 6-month and 12-month PFS rates were 46.7% (95% CI: 28.8-64.5) and 36.4% (95% CI: 19.0-53.7). In multivariate analysis, a significant correlation was observed between a durvalumab treatment duration of 6 months or more and PFS (p = 0.04) as well as OS (p = 0.001). Grade 3 adverse events, including pneumonitis, dermatitis, and colitis, occurred in 10% of the patients. This study suggests that nivolumab plus ipilimumab is effective, especially in patients who have received durvalumab for 6 months or more, and tolerable for patients who relapsed after durvalumab following CCRT.

Abstract
PURPOSE For patients with locally advanced non-small-cell lung cancer (LA-NSCLC) that progressed after definitive chemoradiotherapy (CRT) and durvalumab consolidation therapy, no subsequent standard treatment exists. The type of treatment selected for each timing of disease progression and its efficacy have not been investigated. METHODS We retrospectively enrolled patients with LA-NSCLC or inoperable NSCLC that progressed after definitive CRT and durvalumab consolidation therapy at 15 Japanese institutions. Patients were classified into the following: Early Discontinuation group (disease progression within 6 months after durvalumab initiation), Late Discontinuation group (disease progression from 7 to 12 months after durvalumab initiation), and Accomplishment group (disease progression from 12 months after durvalumab initiation). RESULTS Altogether, 127 patients were analyzed, including 50 (39.4%), 42 (33.1%) and 35 (27.5%) patients from the Early Discontinuation, Late Discontinuation, and Accomplishment groups, respectively. Subsequent treatments were Platinum plus immune checkpoint inhibitors (ICI) in 18 (14.2%), ICI in 7 (5.5%), Platinum in 59 (46.4%), Non-Platinum in 35 (27.6%), and tyrosine kinase inhibitor in 8 (6.3%) patients. In the Early Discontinuation, Late Discontinuation, and Accomplishment groups, 4 (8.0%), 7 (16.7%), and 7 (20.0%) patients were receiving Platinum plus ICI; 21 (42.0%), 22 (52.4%), and 16 (45.7%) were receiving Platinum, and 20 (40.0%), 8 (19.0%), and 7 (20.0%) were receiving Non-Platinum, respectively. No significant difference in progression-free survival was observed in the timing of disease progression. CONCLUSION In patients with LA-NSCLC hat progressed after definitive CRT and durvalumab consolidation therapy, subsequent treatment may change depending on the timing of disease progression.

Abstract
Platinum-based chemotherapy forms the backbone of treatment for many solid cancers. However, resistance inevitably develops in those with advanced disease. Platinum rechallenge is a well-established concept in the management of ovarian cancer, small cell lung cancer and germ cell tumours. In other solid malignancies there is a lack of quality evidence to support platinum rechallenge, yet it is a widely adopted strategy. Often, patients are within the last year of life, making questions of efficacy, treatment-related toxicity and quality of life critical factors for treatment recommendations. In this overview we appraise the available evidence for platinum rechallenge and strategies being developed to attempt resensitisation of tumours to platinum-based chemotherapy.

Efficacy of platinum agents for stage III non-small-cell lung cancer following platinum-based chemoradiotherapy: a retrospective study. BMC Cancer 2022; 22:342. [PMID: 35351059 PMCID: PMC8962203 DOI: 10.1186/s12885-022-09441-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2021] [Accepted: 03/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Platinum-based chemoradiotherapy is the standard treatment for unresectable stage III non-small-cell lung cancer (NSCLC). However, few studies have evaluated the efficacy of subsequent chemotherapy for relapsed NSCLC following platinum-based chemoradiotherapy. This study aimed to evaluate the efficacy of platinum-doublet chemotherapy as a second-line treatment for patients with unresectable stage III NSCLC. METHODS We retrospectively evaluated patients with unresectable stage III NSCLC treated with cytotoxic chemotherapy following platinum-based chemoradiotherapy who were registered in a nationwide registry NSCLC database. Patients were divided into the platinum-doublet chemotherapy (platinum) group and single-agent chemotherapy (non-platinum) group based on the type of second-line chemotherapy. RESULTS The platinum group (n = 119) showed significantly better overall survival (OS) than the non-platinum group (n = 201) (median OS: 21.5 vs. 10.5 months, hazard ratio [HR]: 0.54, 95% confidence interval [CI]: 0.40-0.73, p < 0.001). OS from the beginning of chemoradiotherapy was also significantly better in the platinum group than in the non-platinum group (median OS: 34.9 vs. 21.8 months, HR: 0.58, 95% CI: 0.43-0.79, p = 0.001). In the multivariate analysis, platinum-doublet chemotherapy as second-line therapy, female sex, clinical stage IIIA, and duration of ≥ 8.6 months from the beginning of first-line therapy to the beginning of second-line therapy were associated with significantly better OS. CONCLUSION Platinum-doublet chemotherapy as a second-line therapy may prolong survival in unresectable stage III NSCLC patients following platinum-based chemoradiotherapy. Thus, re-administration of platinum agents may be a promising treatment for unresectable stage III NSCLC treated with platinum-based chemoradiotherapy.

Serum- and glucocorticoid- inducible kinase 2, SGK2, is a novel autophagy regulator and modulates platinum drugs response in cancer cells. Oncogene 2020; 39:6370-6386.

Abstract
For many tumor types chemotherapy still represents the therapy of choice and many standard treatments are based on the use of platinum (PT) drugs. However, de novo or acquired resistance to platinum is frequent and leads to disease progression. In Epithelial Ovarian Cancer (EOC) patients, PT-resistant recurrences are very common and improving the response to treatment still represents an unmet clinical need. To identify new modulators of PT-sensitivity, we performed a loss-of-function screening targeting 680 genes potentially involved in the response of EOC cells to platinum. We found that SGK2 (Serum-and Glucocorticoid-inducible kinase 2) plays a key role in PT-response. We show here that EOC cells relay on the induction of autophagy to escape PT-induced death and that SGK2 inhibition increases PT sensitivity inducing a block in the autophagy cascade due to the impairment of lysosomal acidification. Mechanistically we demonstrate that SGK2 controls autophagy in a kinase-dependent manner by binding and inhibiting the V-ATPase proton pump. Accordingly, SGK2 phosphorylates the subunit V1H (ATP6V1H) of V-ATPase and silencing or chemical inhibition of SGK2, affects the normal autophagic flux and sensitizes EOC cells to platinum. Hence, we identified a new pathway that links autophagy to the survival of cancer cells under platinum treatment in which the druggable kinase SGK2 plays a central role. Our data suggest that blocking autophagy via SGK2 inhibition could represent a novel therapeutic strategy to improve patients' response to platinum.

Abstract
PURPOSE Doublet combination chemotherapy is commonly considered a second-line treatment for advanced non-small cell lung cancer (NSCLC) in China. This multi-institutional retrospective analysis evaluated and compared the efficacy between combination and mono-therapy after platinum-based first-line chemotherapy in Chinese patients with advanced NSCLC. METHODS We retrospectively reviewed 335 patients who received second-line chemotherapy for advanced NSCLC. The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS), response rate (RR) and toxicity. Treatment-free interval (TFI) was used for further stratification analysis. The Cox proportional hazards model was used for multivariate analysis. RESULTS Two hundred and fifty-three patients received doublet combination chemotherapy and 82 received single-agent chemotherapy. PFS was significantly prolonged in combination group compared to single-agent group (median 5.70 vs 3.70 months; HR 0.62; 95% CI 0.45-0.85; p < 0.001). The RR was significantly higher in the combination group than in the single-agent group (29.25% vs. 10.98%; p = 0.001). OS was also prolonged in combination group versus single-agent group (median 13.30 vs. 11.45 months, respectively; HR 0.70; 95% CI 0.52-0.95; p = 0.023). Among patients with TFI of ≥ 6 months, PFS and OS of the combination group were significantly increased than the single-agent group (median PFS, 6.67 vs. 3.80 months, p = 0.002; median OS, 13.60 vs. 11.45 months, p = 0.013). Grade III/IV toxicity was similar between the two groups (p = 0.113). Through multivariate analyses, we found that Eastern Cooperative Oncology Group (ECOG) score (p < 0.001), further-line treatment (p < 0.001) and combination chemotherapy (p = 0.024) were the independent prognostic factors. CONCLUSION Compared with mono-therapy, combination chemotherapy was a better second-line option for Chinese patients with good performance status, especially in those with TFI of ≥ 6 months.

Abstract
Aim: This meta-analysis compared incidence of grade 3-4 neutropenia with ALK inhibitors versus chemotherapy in patients with non-small-cell lung cancer. Materials & methods: PubMed/MEDLINE was searched to identify Phase II and III randomized clinical trials published up to 25 October 2018. Summary incidence, relative risk and corresponding 95% CIs were calculated for grade 3-4 neutropenia. Results: Five randomized clinical trials were included. Relative risk (95% CI) of developing grade 3-4 neutropenia with ALK inhibitor versus chemotherapy was 0.27 (0.07-1.06). Probabilities of developing grade 3-4 neutropenia were 6.56 and 14.19%, respectively; no significant difference was found. Conclusion: In patients with non-small-cell lung cancer, incidence of grade 3-4 neutropenia with ALK-targeted therapy is not significantly different compared with chemotherapy.

Abstract
BACKGROUND Currently, the nonsmall-cell lung cancer (NSCLC) is a worldwide disease, which has very poor influence on life quality, whereas the therapeutic effects of drugs for it are not satisfactory. The aim of our PRISMA-compliant systematic review and meta-analysis was to compare the efficacy and safety of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) with Taxanes in patients with lung tumors. METHODS We collected randomized controlled trials (RCTs) of EGFR-TKIs (gefitinib, erlotinib) versus Taxanes (docetaxel, paclitaxel) for the treatment of NSCLC by searching PubMed, EMbase, and the Cochrane library databases until April, 2016. The extracted data on progression-free survival (PFS), progression-free survival rate (PFSR), overall survival (OS), overall survival rate (OSR), objective response rate (ORR), disease control rate (DCR), quality of life (QoL), and adverse event rates (AEs) were pooled. Disease-relevant outcomes were evaluated using RevMan 5.3.5 software and STATA 13.0 software. RESULTS We systematically searched 26 RCTs involving 11,676 patients. The results showed that EGFR-TKIs could significantly prolong PFS (hazard ratio [HR] = 0.78, 95% confidence interval [CI]: 0.66-0.92) and PFSR (risk ratio [RR] = 2.10, 95% CI: 1.17-3.77), and improve ORR (RR = 1.62, 95% CI: 1.38-1.91) and QoL. EGFR-TKIs had similar therapeutic effects to taxanes with respect to OS (HR = 1.00, 95% CI: 0.95-1.05) and OSR (RR = 1.03, 95% CI: 0.94-1.14). Furthermore, there were no significant differences between them in DCR (RR = 0.95, 95% CI: 0.88-1.03). Finally, EGFR-TKIs were superior to taxanes in most of all grades or grade ≥3 AEs. CONCLUSION In the efficacy and safety evaluation, EGFR-TKIs had an advantage in the treatment of NSCLC, especially for patients with EGFR mutation-positive. The project was prospectively registered with PROSPERO database of systematic reviews, with number CRD42016038700.
