Project description:In this exploratory prospective observational study on 40 small cell lung cancer (SCLC) patients treated with a combination of chemotherapy and immune checkpoint inhibitors, blood immune cells were characterized by multi-color flow cytometry at the baseline and at the third therapy cycle. The numbers of neutrophils and of T-, B-, and NK cells, as well as the frequency of HLA-DRlow monocytes, 6-SulfoLacNAc (slan)+ non-classical monocytes and circulating dendritic cell (DC) subtypes were determined. The prognostic value of the parameters was evaluated by the patient's survival analysis with overall survival (OS) as the primary endpoint. In addition, blood cell parameters from SCLC patients were compared to those from non-SCLC (NSCLC). The global median OS of patients was 10.4 ± 1.1 months. Disease progression (15% of patients) correlated with a higher baseline neutrophil/lymphocyte ratio (NLR), more HLA-DRlow monocytes, and lower NK cell and DC numbers. The risk factors for poor OS were the presence of brain/liver metastases, a baseline NLR ≥ 6.1, HLA-DRlow monocytes ≥ 21% of monocytes, slan+ non-classical monocytes < 0.12%, and/or CD1c+ myeloid DC < 0.05% of leukocytes. Lymphocytic subpopulations did not correlate with OS. When comparing biomarkers in SCLC versus NSCLC, SCLC had a higher frequency of brain/liver metastases, a higher NLR, the lowest DC frequencies, and lower NK cell numbers. Brain/liver metastases had a substantial impact on the survival of SCLC patients. At the baseline, 45% of SCLC patients, but only 24% of NSCLC patients, had between three and five risk factors. A high basal NLR, a high frequency of HLA-DRlow monocytes, and low levels of slan+ non-classical monocytes were associated with poor survival in all lung cancer histotypes. Thus, the blood immune cell signature might contribute to a better prediction of SCLC patient outcomes and may uncover the pathophysiological peculiarities of this tumor entity.

Project description:Until recently, the treatment of patients with advanced non-small-cell lung cancer (NSCLC) whose tumors did not have a targetable genetic alteration was cytotoxic chemotherapy alone. This treatment provided only modest survival benefit. The introduction of immune checkpoint inhibitors targeting programmed cell death 1 protein (PD-1) signaling pathway in the treatment of patients with NSCLC has had significant effect on patient survival. Atezolizumab, nivolumab and pembrolizumab have been shown to be superior to chemotherapy in patients with recurrent NSCLC. Recently, pembrolizumab has been combined with chemotherapy in the front-line setting and has demonstrated an improvement in overall survival in NSCLC patients as compared to chemotherapy alone. In this review we will focus on the clinical trials that led to approval of combination pembrolizumab and chemotherapy as first-line treatment for patients with advanced NSCLC as well as discuss other combinations of immunotherapy and chemotherapy that have also been evaluated.

Project description:Neoadjuvant immune checkpoint inhibitor (ICI) treatment + chemotherapy has been used for locally advanced non-small cell lung cancer (NSCLC); however, evidence regarding the efficacy of this treatment is insufficient, particularly in Chinese patients. Therefore, the aim of the present study was to evaluate the efficacy and safety of neoadjuvant ICI treatment + chemotherapy compared with neoadjuvant chemotherapy alone for locally advanced NSCLC. For this, 50 patients with locally advanced NSCLC were retrospectively analyzed; of these, 23 patients received pre-operative camrelizumab or sintilimab + chemotherapy (ICI + chemo group) and 27 patients received pre-operative chemotherapy alone (chemo group). The objective response rate (73.9 vs. 44.4%, P=0.035) was superior in the ICI + chemo group compared with the chemo group. Nevertheless, surgical resection rate (100.0 vs. 88.9%, P=0.240), major pathological response (60.9 vs. 41.7%, P=0.188) and complete pathological response (CPR; 30.4 vs. 8.3%, P=0.072) were not significantly different in the ICI + chemo group compared with the chemo group. Following adjustment, ICI + chemo was independently associated with an elevated CPR (P=0.029). Disease-free survival (DFS) was prolonged in the ICI + chemo group compared with the chemo group (1-year DFS, 94.1 vs. 81.6%; 2-year DFS, 80.7 vs. 42.9%; P=0.047), while no significant differences were observed in overall survival (OS; 1-year OS, 100.0 vs. 95.7%; 2-year OS, 90.0 vs. 64.9%; P=0.187). Additionally, the majority of adverse event incidences (apart from leukopenia) did not differ significantly between the ICI + chemo and chemo groups (all P>0.050). On the whole, the present study demonstrated that neoadjuvant ICI treatment + chemotherapy exhibited adequate efficacy and acceptable toxicity compared with chemotherapy alone in patients with locally advanced NSCLC.

Project description:IntroductionClinical evidence suggests that first-line immune checkpoint inhibitor (ICI) combination therapies can improve survival in patients with advanced non-squamous non-small cell lung cancer (nsq-NSCLC). However, the optimal strategy remains unknown without a systematic comparison of their long-term effects.MethodsWe performed a systematic review and network meta-analysis by retrieving up-to-date literature from PubMed® (National Library of Medicine, Bethesda, MD, USA), Embase® (Elsevier, Amsterdam, Netherlands), MEDLINE® (National Library of Medicine), ClinicalTrials.gov (National Library of Medicine), and major international conference publications. Published studies and abstracts comparing first-line ICI combination therapies with other treatments for patients with advanced nsq-NSCLC were included. Restricted mean survival time (RMST) was measured over 12 months for progression-free survival (PFS) and 18 months for overall survival (OS), and the Royston-Parmar model was used to extrapolate and compare data for the long-term outcomes.ResultsWe included a total of 11 trials involving 12 therapies and 6,130 patients. Pembrolizumab plus chemotherapy exhibited the best overall survival (OS) benefit at both 18 and 60 months [RMST = 2.95, 95% confidence interval (CI) 1.96 to 3.97; life-years gained over a 5-year period = 2.18 years]. Nivolumab plus bevacizumab plus chemotherapy was found to present the best progression-free survival (PFS) benefit at 12 months (RMST 3.02, 95% CI 2.11 to 3.91), whereas atezolizumab plus bevacizumab plus chemotherapy showed the best PFS benefit at 36 months (life-years gained over 3 years = 1.22 years). Subgroup analyses showed that among patients with programmed death-ligand 1 (PD-L1) expression ≥ 50%, atezolizumab plus chemotherapy and nivolumab plus ipilimumab resulted in superior OS benefits at 18 and 60 months, respectively. Among patients with PD-L1 expression< 1%, pembrolizumab plus chemotherapy was associated with OS benefits at both 18 and 60 months. Sintilimab plus chemotherapy was associated with relatively fewer grade ≥ 3 adverse events than other ICI combination therapies.ConclusionOur results show that ICI combination therapies showed better survival benefits than chemotherapy. Pembrolizumab plus chemotherapy could provide the best OS benefits to patients with advanced nsq-NSCLC, whereas atezolizumab plus bevacizumab plus chemotherapy could bring the best PFS benefits. The optimal ICI combination therapy varies depending on PD-L1 expression level.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=325005, identifier CRD42022325005.

Project description:BackgroundRechallenge with platinum-combination chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) after disease progression on platinum-combination chemotherapy occasionally leads to a favorable response. The efficacy and safety of platinum-combination chemotherapy with or without immune-checkpoint inhibitor (ICI) for patients with recurrent NSCLC after surgery followed by adjuvant platinum-doublet chemotherapy remains uncertain.MethodsPatients who relapsed after surgery plus adjuvant platinum-doublet chemotherapy and received platinum-combination chemotherapy with or without ICI between April 2011 and March 2021 at four Nippon Medical School hospitals were retrospectively analyzed.ResultsAmong 177 patients who received adjuvant platinum-doublet chemotherapy after surgery, a total of 30 patients who received platinum-combination rechemotherapy with or without ICI after relapse were included in this study. Seven patients received ICI-combined chemotherapy. The median disease-free survival (DFS) after surgery was 13.6 months. The objective response rate and disease-control rate were 46.7% and 80.0%, respectively. The median progression-free survival and overall survival were 10.2 and 37.5 months, respectively. Patients with longer DFS (≥12 months) had a better prognosis than others. The most common grade ≥3 toxicity associated with this treatment was neutropenia (33%). Grade ≥3 immune-related adverse events were pneumonitis (14%) and colitis (14%). Treatment-related deaths did not occur in this study.ConclusionPlatinum-combination chemotherapy with or without ICI for patients with postoperative recurrent NSCLC who previously received adjuvant platinum-doublet chemotherapy was effective and safe. In particular, this therapy may be promising for patients with longer DFS.

Project description:IntroductionPlatin-based chemotherapy (CT) has long been the first-line standard-of-care for patients with extensive-stage small-cell lung cancer (ES-SCLC). Adding immune-checkpoint inhibitor(s) to CT (ICI+CT) in this setting is an option of interest, although its benefit is apparently modest.MethodsThis meta-analysis was conducted on randomized trials comparing first-line ICI+CT versus CT alone for ES-SCLC. Outcomes included overall survival (OS), progression-free survival (PFS), objective response rate (ORR), response at 12 months and adverse events (AEs). Subgroup analyses were computed according to the immunotherapy used, performance status (PS), age, platinum salt, liver metastases and brain metastases at diagnosis.ResultsThe literature search identified one randomized phase II (ECOG-ACRIN-5161) and four phase III trials (CASPIAN, IMPOWER-133, KEYNOTE-604 and Reck et al. 2016) that included 2775 patients (66% males, 95% smokers, median age: 64 years, PS = 0 or 1). ICI+CT was significantly associated (hazard ratio [95% confidence interval]) with prolonged OS [0.82 (0.75-0.89); p < 0.00001] and PFS [0.81 (0.75-0.87); p < 0.00001], with OS benefits for anti-PD-L1 [0.73 (0.63-0.85); p < 0.0001] or anti-PD-1 [0.76 (0.63-0.93); p < 0.006] but not for anti-CTLA-4 [0.90 (0.80-1.01), p = 0.07]. ORRs for ICI+CT or CT alone were comparable [odds ratio 1.12 (0.97-1.00); p = 0.12], but responses at 12 months favored ICI+CT [4.16 (2.81-6.17), p < 0.00001]. Serious grade-3/4 AEs were more frequent with ICI+CT [odds ratio 1.18 (1.02-1.37); p = 0.03]. Compared with CT, no ICI+CT benefit was found for ES-SCLC with brain metastases at diagnosis [HR 1.14 (0.87-1.50); p = 0.34].ConclusionsFirst-line ICI+CT appears to be superior to CT alone for ES-SCLC except for patients with brain metastases at diagnosis.

Project description:ImportanceImmune checkpoint inhibitor (ICI) monotherapy with pembrolizumab and ICI plus chemotherapy have been approved as first-line treatments for non-small cell lung cancer (NSCLC) for patients with a programmed cell death ligand-1 (PD-L1) tumor proportion score (TPS) of 50% or more, but the choice between these 2 therapeutic options is unclear.ObjectiveTo clarify the association of a history of concurrent medication use with treatment outcomes for ICIs with or without chemotherapy in patients with NSCLC with a high PD-L1 TPS and to determine whether these clinical histories are biomarkers for appropriate treatment selection.Design, setting, and participantsThis retrospective, multicenter cohort study at 13 hospitals in Japan included patients with advanced NSCLC with a PD-L1 TPS of 50% or more who had received pembrolizumab ICI monotherapy or ICI plus chemotherapy as the initial treatment between March 2017 and December 2020. The median (IQR) follow-up duration was 18.5 (9.2-31.2) months. Data were analyzed from April 2022 through May 2023.ExposureICI monotherapy with pembrolizumab or ICI plus chemotherapy as first-line treatment.Main outcomes and measuresThe primary analysis was the association of treatment outcomes with baseline patient characteristics, including concomitant drug history, after propensity score matching. Cox proportional hazard models were used to determine the associations of patient characteristics with survival outcomes. Logistic regression analysis was used to determine the association of concomitant medication history with treatment outcomes and other patient characteristics.ResultsA total of 425 patients with NSCLC were enrolled in the study including 271 patients (median [range] age, 72 [43-90] years; 215 [79%] men) who were treated with pembrolizumab monotherapy as the first-line treatment and 154 patients (median [range] age, 69 [36-86] years; 121 [79%] men) who were treated with ICI plus chemotherapy as the first-line treatment. In multivariable analysis, a history of proton pump inhibitor (PPI) use was independently associated with shorter progression-free survival (PFS) in the pembrolizumab monotherapy group (hazard ratio [HR], 1.38; 95% CI, 1.00-1.91; P = .048), but not in the ICI plus chemotherapy group. In patients with a PPI history, both the median (IQR) PFS (19.3 [9.0 to not reached] months vs 5.7 [2.4 to 15.2] months; HR, 0.38; 95% CI, 0.20-0.72; P = .002) and the median (IQR) overall survival (not reached [9.0 months to not reached) vs 18.4 [10.5 to 50.0] months; HR, 0.43; 95% CI, 0.20-0.92; P = .03) were significantly longer in the ICI plus chemotherapy group than in the pembrolizumab monotherapy group. In patients without a history of PPI use, both the median (IQR) PFS (18.8 months [6.6 months to not reached] vs 10.6 months [2.7 months to not reached]; HR, 0.81; 95% CI, 0.56-1.17; P = .26) and the median (IQR) overall survival (not reached [12.6 months to not reached] vs 29.9 [13.3 to 54.3] months, HR, 0.75; 95% CI, 0.48-1.18; P = .21) did not differ between groups.Conclusions and relevanceThis cohort study found that a history of PPI use could be an important clinical factor in treatment decision-making for patients with NSCLC with a PD-L1 TPS of 50% or more.

Project description:BackgroundSingle agent immune checkpoint inhibitors (ICIs) improve survival outcomes compared to chemotherapy for advanced non-small cell lung cancer (NSCLC), but treatment efficacy widely varies. The combination of ICIs with chemotherapy has shown promising efficacy over chemotherapy alone; however, whether this strategy is superior to single agent ICIs for the treatment of advanced NSCLC remains unknown.MethodsThe records of 109 patients with advanced NSCLC who were administered at least one cycle of ICIs were retrospectively reviewed. Patients were grouped based on the presence or absence of a chemotherapy treatment combination. Efficacy and survival outcomes were analyzed.ResultSixty-nine (58.0%) patients received single agent ICIs (ICI group) and 50 (42.0%) received ICIs and chemotherapy (ICC group). The median (3.2 vs. 3.0 months; P = 0.025) and one-year (34.5 vs. 9.6%; P = 0.026) progression-free survival (PFS) rates were significantly better in the ICC than in the ICI group. The superior efficacy of ICC remained in the propensity score matched pairs (median PFS 3.2 vs. 2.6 months, P = 0.032; 1-year PFS 35.2 vs. 7.6%; P = 0.035). Eastern Cooperative Oncology Group performance status 0-1 (HR 0.37, 95% CI 0.22-0.62; P < 0.001) and the ICC group (HR 0.56, 95% CI 0.34-0.94; P = 0.028) were predictive of PFS. Subgroup-to-chemotherapy interaction revealed improved risk reduction for adenocarcinoma and EGFR mutation.ConclusionCombing chemotherapy with ICIs improved treatment efficacy over ICIs alone. The additional efficacy of chemotherapy may differ between histological subtypes and EGFR mutation status.
