Prognostic Impact of Blood Lipid Profile in Patients With Advanced Solid Tumors Treated With Immune Checkpoint Inhibitors: A Multicenter Cohort Study
Background Specific components of lipid profile seem to differently impact on immune activity against cancer and unraveling their prognostic role in patients with solid cancer treated with immune checkpoint inhibitors (ICIs) is needed. Materials and Methods We retrospectively collected baseline clinicopathological characteristics including circulating lipid profile (total cholesterol [TC], triglycerides [TG], low-density lipoproteins [LDL], high-density lipoproteins [HDL]) of patients with consecutive solid cancer treated with ICIs, and we investigated their role in predicting clinical outcomes. Results At a median follow-up of 32.9 months, among 430 enrolled patients, those with TC ≥ 200 mg/dl showed longer median progression-free survival (mPFS; 6.6 vs. 4.7 months, P = .4), although not reaching statistical significance, and significantly longer median overall survival (mOS; 19.4 vs. 10.8 months, P = .02) compared to those with TC < 200 mg/dl. Conversely, patients with TG ≥150 mg/dl displayed shorter PFS (3.4 vs. 5.1 months, P = .02) and OS (7.1 vs. 12.9 months, P = .009) compared to those with TG <150 mg/dl. TC and TG were then combined in a “LIPID score” identifying three subgroups: good-risk (GR) (TC ≥200 mg/dl and TG <150 mg/dl), intermediate-risk (IR) (TC <200 mg/dl and TG <150 mg/dl or TC ≥200 mg/dl and TG ≥150 mg/dl) and poor-risk (PR) (TC <200 mg/dl and TG ≥150 mg/dl). The mPFS of GR, IR, and PR groups was 7.8, 4.3, and 2.5 months, respectively (P = .005); mOS of GR, IR, and PR was 20.4, 12.4, and 5.3 months, respectively (P < .001). At multivariable analysis, the PR profile represented an independent poor prognostic factor for both PFS and OS. Conclusions We developed a lipid score that defined subgroups of patients with cancer who differently benefit from ICIs. Further mechanistic insights are warranted to clarify the prognostic and predictive role of lipid profile components in patients treated with ICIs. Specific components of lipid profile have different effects on immune activity against cancer. This study aimed to unravel their prognostic role in solid tumors treated with immune checkpoint inhibitors.
Hyperprogressive Disease upon Immune Checkpoint Blockade: Focus on Non–small Cell Lung Cancer
Purpose of ReviewDescribe the controversial aspects of hyperprogressive disease (HPD) definition, mechanisms, and biomarkers.Recent FindingsAlthough immune checkpoint inhibitors (ICIs) demonstrated a survival benefit in non–small cell lung cancer (NSCLC), an acceleration of tumor growth during ICI, defined as HPD, was reported in ~ 13–26% of NSCLC patients and correlated with worse survival compared with conventional progression. Different criteria have been used for HPD definition. The main limitation for the use of tumor growth rate and tumor growth kinetics variations is its inapplicability for patients without a pre-baseline imaging or progressing on non-measurable lesions. On the contrary, time to treatment failure and clinical criteria (i.e., worsening of performance status, presence of new lesions, or metastatic spread to different sites) can be useful in the above-mentioned settings but do not consent an assessment of tumor growth before ICI initiation. Several mechanisms of HPD have been proposed so far, involving both adaptive and innate immunity or based on cell-autonomous signals of cancer growth triggered by ICI. The characterization of HPD biomarkers and the identification and validation on large series of one or more mechanistic explanations for the HPD phenomenon are of paramount significance to avoid detrimental immunotherapy in a subgroup of patients and exploit novel therapeutic targets for future immunotherapy combinations.SummaryHPD occur in a subgroup of NSCLC patients treated with ICI. Several definitions and mechanisms have been proposed and a consensus on HPD criteria and biological bases is currently lacking.
Focus on genetic and epigenetic events of colorectal cancer pathogenesis: implications for molecular diagnosis
Originally, colorectal cancer (CRC) tumorigenesis was understood as a multistep process that involved accumulation of tumor suppressor genes and oncogenes mutations, such as APC , TP53 and KRAS . However, this assumption proposed a relatively limited repertoire of genetic alterations. In the last decade, there have been major advances in knowledge of multiple molecular pathways involved in CRC pathogenesis, particularly regarding cytogenetic and epigenetic events. Microsatellite instability, chromosomal instability and CpG island methylator phenotype are the most analyzed cytogenetic changes, while DNA methylation, modifications in histone proteins and microRNAs (miRNAs) were analyzed in the field of epigenetic alterations. Therefore, CRC development results from interactions at many levels between genetic and epigenetic amendments. Furthermore, hereditary cancer syndrome and individual or environmental risk factors should not be ignored. The difficulties in this setting are addressed to understand the molecular basis of individual susceptibility to CRC and to determine the roles of genetic and epigenetic alterations, in order to yield more effective prevention strategies in CRC patients and directing their treatment. This review summarizes the most investigated biomolecular pathways involved in CRC pathogenesis, their role as biomarkers for early CRC diagnosis and their possible use to stratify susceptible patients into appropriate screening or surveillance programs.
Sex differences in patients with Non-Small Cell Lung Cancer harboring driver fusions treated with tyrosine kinase inhibitors: a systematic review
Background: While targeted therapies have transformed the treatment landscape of oncogene-addicted non-small cell lung cancer (NSCLC), the influence of sex on treatment outcomes remains insufficiently understood. Objectives: This systematic review aimed to investigate the impact of sex on clinical outcomes in patients with NSCLC harboring driver fusions treated with targeted therapies enrolled in clinical trials. Data sources and methods: A comprehensive literature search was conducted using PubMed, Embase, and relevant conference abstracts to identify phase III randomized and early clinical trials that reported sex-specific data, including progression-free survival (PFS), overall survival (OS), overall response rate, and adverse events (AEs), in patients with fusion-positive NSCLC treated with tyrosine kinase inhibitors (TKIs). Results: This review involved 10 studies reporting PFS data and 3 studies with OS data, focusing on first-line treatments for ALK fusion (9 studies) and RET fusion-positive (1 study) NSCLC. Pooled analysis of hazard ratios (HRs) for PFS and OS in ALK inhibitors trials revealed no significant differences in survival outcomes based on sex. Additionally, none of the studies provided data on sex-based differences in response rates or toxicities, highlighting a significant knowledge gap regarding the impact of sex on secondary outcomes in targeted therapy. Conclusion: This review found no significant sex-related differences in survival outcomes among patients treated with ALK inhibitors. However, the lack of data on sex-specific response and toxicity emphasizes the need for future research to better understand the role of sex in modulating treatment outcomes and treatment decisions with TKIs. Plain language summary Understanding sex differences in lung cancer treatment outcomes with targeted therapies Why was this review conducted? Lung cancer treatments have advanced significantly with the use of targeted therapies, which are designed to attack specific cancer mutations. However, it is not clear whether a patient's sex influences how well these treatments work. This review looks at whether men and women respond differently to certain targeted treatments for non-small cell lung cancer (NSCLC) to help doctors make better treatment decisions. What did the researchers do? The research team reviewed studies that included both men and women with lung cancer caused by specific genetic changes (called fusion-positive NSCLC). These patients were treated with medications known as tyrosine kinase inhibitors (TKIs), which target cancer-related proteins. The studies were analyzed to see if there were any differences in progression-free survival and overall survival between men and women. What did the researchers find? The review included ten studies looking at how long patients lived without their cancer getting worse and three studies looking at overall survival. These studies focused on patients with two specific genetic changes in their cancer: ALK and RET fusions. The researchers found no major differences between men and women in terms of survival. However, they noted that none of the studies provided information about differences in side effects or how well the cancer responded to treatment between men and women. This is a gap in the research that needs to be addressed. What do the findings mean? This review suggests that, so far, there is no evidence that men and women with NSCLC respond differently to targeted therapies when it comes to survival. However, the lack of data on other important outcomes, like side effects, means that more research is needed to fully understand if sex plays a role in how well these treatments work.
Beyond First-Line Immunotherapy: Potential Therapeutic Strategies Based on Different Pattern Progressions: Oligo and Systemic Progression
First-line immune-checkpoint inhibitor (ICI)-based therapy has deeply changed the treatment landscape and prognosis in advanced non-small cell lung cancer (aNSCLC) patients with no targetable alterations. Nonetheless, a percentage of patients progressed on ICI as monotherapy or combinations. Open questions remain on patients’ selection, the identification of biomarkers of primary resistance to immunotherapy and the treatment strategies to overcome secondary resistance to first-line immunotherapy. Local ablative approaches are the main therapeutic strategies in oligoprogressive disease, and their role is emerging in patients treated with immunotherapy. Many therapeutic strategies can be adapted in aNSCLC patients with systemic progression to personalize the treatment approach according to re-characterization of the tumors, previous ICI response, and type of progression. This review’s aim is to highlight and discuss the current and potential therapeutic approaches beyond first-line ICI-based therapy in aNSCLC patients based on the pattern of disease progression (oligoprogression versus systemic progression).
Evaluation of Drug—Drug Interactions in EGFR-Mutated Non-Small-Cell Lung Cancer Patients during Treatment with Tyrosine-Kinase Inhibitors
(1) Background. The onset of a drug–drug interaction (DDI) may affect treatment efficacy and toxicity of advanced non-small-cell lung cancer (aNSCLC) patients during epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitor (TKI) use. Here we present the use of Drug-PIN® (Personalized Interactions Network) software to detect DDIs in aNSCLC patients undergoing EGFR-TKIs. (2) Methods. We enrolled patients with Stage IV aNSCLC already treated with or candidates to receive EGFR-TKIs, in any line; ECOG PS 0–2; taking at least one concomitant drug. Cancer treatments, concomitant drugs, and clinical and laboratory data were collected and inserted in Drug-PIN®. (3) Results. Ninety-two patients, median age of 68.5 years (range 43–89), were included. In total, 20 clinically relevant DDIs needing medical intervention in a total of 14 patients were identified; the 14 major DDIs were related to a high-grade interaction between TKIs and SSRIs, antipsychotics, antiepileptics, H2-receptor antagonist and calcium antagonists. A negative association between statin intake and PFS was identified (p = 0.02; HR 0.281, 95% CI 0.096–0.825). (4) Conclusions. This is the first retrospective study assessing the prevalence of DDIs, the clinical need for medical intervention and the impact of concomitant drugs on EGFR-TKIs survival in aNSCLC.
Somatostatin analogs in association with peptide receptor radionucleotide therapy in advanced well-differentiated NETs
Data from 69 well-differentiated gastroenteropancreatic neuroendocrine tumors treated with peptide receptor radionucleotide therapy + somatostatin analogs (SSAs) after SSA treatment failure were evaluated. We identified two groups: S1 – patients who kept the same SSA treatment beyond progression; S2 – patients who switched the SSA with another SSA after progression. Median progression-free survival was 53 and 127 months in S1 and S2, respectively (p = 0.001; hazard ratio: 0.31; 95% CI: 0.15–0.63). Median overall survival was 69 versus 150 months in S1 and S2, respectively (p = 0.004; hazard ratio: 0.32; 95% CI: 0.14–0.71). In patients with advanced well-differentiated gastroenteropancreatic neuroendocrine tumors treated with peptide receptor radionucleotide therapy plus SSA after SSA failure, the ‘switch’ strategy of SSA after progression improve progression-free survival and overall survival.
Everolimus treatment for neuroendocrine tumors: latest results and clinical potential
Neuroendocrine tumors (NETs) are a heterogeneous class of diseases characterized by challenging management. Preclinical evidence shows that the PI3K/AKT/mTOR signaling pathway plays a central role in the pathogenesis and progression of NETs. Everolimus is a direct inhibitor of this pathway, and therefore this molecule appears to be a well-grounded strategy for the treatment of NETs, capable of changing clinical practice. The efficacy and safety of everolimus was demonstrated in the RADIANT trials. In this work, we comment on the results of the RADIANT trials, and other recent key evidence from fully published clinical trials on everolimus, and we discuss the current role of everolimus in the treatment of NETs.
Predicting the Role of DNA Polymerase β Alone or with KRAS Mutations in Advanced NSCLC Patients Receiving Platinum-Based Chemotherapy
Clinical data suggest that only a subgroup of non-small cell lung cancer (NSCLC) patients has long-term benefits after front-line platinum-based therapy. We prospectively investigate whether KRAS status and DNA polymerase β expression could help identify patients responding to platinum compounds. Prospectively enrolled, advanced NSCLC patients treated with a first-line regimen containing platinum were genotyped for KRAS and centrally evaluated for DNA polymerase β expression. Overall survival (OS), progression-free survival (PFS), and the objective response rate (ORR) were recorded. Patients with KRAS mutations had worse OS (hazard ratio (HR): 1.37, 95% confidence interval (95% CI): 0.70–2.27). Negative DNA polymerase β staining identified a subgroup with worse OS than patients expressing the protein (HR: 1.43, 95% CI: 0.57–3.57). The addition of KRAS to the analyses further worsened the prognosis of patients with negative DNA polymerase β staining (HR: 1.67, 95% CI: 0.52–5.56). DNA polymerase β did not influence PFS and ORR. KRAS may have a negative role in platinum-based therapy responses in NSCLC, but its impact is limited. DNA polymerase β, when not expressed, might indicate a group of patients with poor outcomes. KRAS mutations in tumors not expressing DNA polymerase β further worsens survival. Therefore, these two biomarkers together might well identify patients for whom alternatives to platinum-based chemotherapy should be used.
Dostarlimab or pembrolizumab plus chemotherapy in previously untreated metastatic non-squamous non-small cell lung cancer: the randomized PERLA phase II trial
PERLA is a global, double-blind, parallel phase II trial (NCT04581824) comparing efficacy and safety of anti–PD-1 antibodies dostarlimab and pembrolizumab, plus chemotherapy (DCT and PCT, respectively) as first-line treatment in patients with metastatic non-squamous NSCLC without known targetable genomic aberrations. Patients stratified by PD-L1 tumor proportion score and smoking status were randomized 1:1, receiving ≤35 cycles 500 mg dostarlimab or 200 mg pembrolizumab, ≤35 cycles 500 mg/m 2 pemetrexed and ≤4 cycles cisplatin (75 mg/m 2 ) or carboplatin (AUC 5 mg/ml/min) Q3W. Primary endpoint was overall response rate (ORR) (blinded independent central review). Secondary endpoints include progression-free survival (PFS) based on investigator assessment, overall survival (OS) and safety. Exploratory endpoints include ORR by PD-L1 subgroup and duration of response. PERLA met its pre-specified endpoint. ORR (n/N; 95% CI) is 45% (55/121; 36.4–54.8) for DCT and 39% (48/122; 30.6–48.6) for PCT (data cut-off: 07 July 23), numerically favoring dostarlimab in PD-L1-positive subgroups. Median PFS (months [95% CI]) is 8.8 (6.7–10.4) for DCT and 6.7 (4.9–7.1) for PCT (HR 0.70 [95% CI: 0.50–0.98]; data cut-off: 04 August 22). Median OS (months [95% CI]) is 19.4 (14.5–NR) for DCT and 15.9 (11.6–19.3) for PCT (HR 0.75 [95% CI: 0.53–1.05]) (data cut-off: 07 July 23). Safety profiles are similar between groups. In this study, DCT shows similar efficacy to PCT and demonstrates clinical efficacy as first-line treatment for patients with metastatic non-squamous NSCLC. Several PD-(L)1 inhibitors have been approved or are in development for the treatment of NSCLC, showing promising efficacy and tolerable safety profiles. Here, the authors present a randomized phase II clinical trial comparing two different anti-PD-1 antibodies, dostarlimab and pembrolizumab, both combined with chemotherapy as first-line treatment in patients with metastatic NSCLC.
