Clinical Impact of COVID-19 Outbreak on Cancer Patients: A Retrospective Study
Background: Coronavirus disease (COVID-19), an acute respiratory syndrome caused by a novel severe acute respiratory syndrome coronavirus (SARS-CoV-2), has rapidly spread worldwide, significantly affecting the outcome of a highly vulnerable group such as cancer patients. The aim of the present study was to evaluate the clinical impact of COVID-19 infection on outcome and oncologic treatment of cancer patients. Patient and methods: We retrospectively enrolled cancer patients with laboratory and/or radiologic confirmed SARS-CoV-2 infection, admitted to our center from February to April 2020. Descriptive statistics were used to summarize the clinical data and univariate analyses were performed to investigate the impact of anticancer treatment modifications due to COVID-19 outbreak on the short-term overall survival (OS). Results: Among 61 patients enrolled, 49 (80%) were undergoing anticancer treatment and 41 (67%) had metastatic disease. Most patients were men; median age was 68 years. Median OS was 46.6 days (40% of deaths occurred within 20 days from COVID-19 diagnosis). Among 59 patients with available data on therapeutic course, 46 experienced consequences on their anticancer treatment schedule. Interruption or a starting failure of the oncologic therapy correlated with significant shorter OS. Anticancer treatment delays did not negatively affect the OS. Lymphocytopenia development after COVID was significantly associated with worst outcome. Conclusions: COVID-19 diagnosis in cancer patients may affect their short-term OS, especially in case of interruption/starting failure of cancer therapy. Maintaining/delaying cancer therapy seems not to influence the outcome in selected patients with recent COVID-19 diagnosis
Integrated MRI–Immune–Genomic Features Enclose a Risk Stratification Model in Patients Affected by Glioblastoma
Simple Summary: Despite crucial scientific advances, Glioblastoma (GB) remains a fatal disease with
limited therapeutic options and a lack of suitable biomarkers. The unveiled competence of the brain
immune system together with the breakthrough advent of immunotherapy has shifted the present
translational research on GB towards an immune-focused perspective. Several clinical trials targeting
the immunosuppressive GB background are ongoing. So far, results are inconclusive, underpinning
our partial understanding of the complex cancer-immune interplay in brain tumors. High throughput
Magnetic Resonance (MR) imaging has shown the potential to decipher GB heterogeneity, including
pathologic and genomic clues. However, whether distinct GB immune contextures can be deciphered
at an imaging scale is still elusive, leaving unattained the non-invasive achievement of prognostic
and predictive biomarkers. Along these lines, we integrated genetic, immunopathologic and imaging
features in a series of GB patients. Our results suggest that multiparametric approaches might
offer new efficient risk stratification models, opening the possibility to intercept the critical events
implicated in the dismal prognosis of GB.
Abstract: Background: The aim of the present study was to dissect the clinical outcome of GB patients
through the integration of molecular, immunophenotypic and MR imaging features. Methods: We
enrolled 57 histologically proven and molecularly tested GB patients (5.3% IDH-1 mutant). Two-
Dimensional Free ROI on the Biggest Enhancing Tumoral Diameter (TDFRBETD) acquired by MRI
sequences were used to perform a manual evaluation of multiple quantitative variables, among which
we selected: SD Fluid Attenuated Inversion Recovery (FLAIR), SD and mean Apparent Diffusion
Coefficient (ADC). Characterization of the Tumor Immune Microenvironment (TIME) involved the
immunohistochemical analysis of PD-L1, and number and distribution of CD3+, CD4+, CD8+ Tumor
Infiltrating Lymphocytes (TILs) and CD163+ Tumor Associated Macrophages (TAMs), focusing on
immune-vascular localization. Genetic, MR imaging and TIME descriptors were correlated with
overall survival (OS). Results: MGMT methylation was associated with a significantly prolonged OS
(median OS = 20 months), while no impact of p53 and EGFR status was apparent. GB cases with high
mean ADC at MRI, indicative of low cellularity and soft consistency, exhibited increased OS (median
OS = 24 months). PD-L1 and the overall number of TILs and CD163+TAMs had a marginal impact
on patient outcome. Conversely, the density of vascular-associated (V) CD4+ lymphocytes emerged
as the most significant prognostic factor (median OS = 23 months in V-CD4high vs. 13 months in
V-CD4low, p = 0.015). High V-CD4+TILs also characterized TIME of MGMTmeth GB, while p53mut
appeared to condition a desert immune background. When individual genetic (MGMTunmeth), MR
imaging (mean ADClow) and TIME (V-CD4+TILslow) negative predictors were combined, median OS was 21 months (95% CI, 0–47.37) in patients displaying 0–1 risk factor and 13 months (95% CI
7.22–19.22) in the presence of 2–3 risk factors (p = 0.010, HR = 3.39, 95% CI 1.26–9.09). Conclusion:
Interlacing MRI–immune–genetic features may provide highly significant risk-stratification models
in GB patients
Exploring genetic and immune underpinnings of the sexual dimorphism in tumor response to immune checkpoints inhibitors: A narrative review
Introduction
In spite of the undisputed relevance of sex as critical biologic variable of the immune landscape, still limited is our understanding of the basic mechanisms implicated in sex-biased immune response thereby conditioning the therapeutic outcome in cancer patients. This hindrance delays the actual attempts to decipher the heterogeneity of cancer and its immune surveillance, further digressing the achievement of predictive biomarkers in the current immunotherapy-driven scenario. Body: The present review concisely reports on genetic, chromosomal, hormonal, and immune features underlying sex-differences in the response to immune checkpoint inhibitors (ICIs). In addition to outline the need of robust data on ICI pharmaco-kinetics/dynamics, our survey might provide new insights on sex determinants of ICI efficacy and suggests uncovered pathways that warrant prospective investigations.
Conclusion
According to a sharable view, we propose to widely include sex among the co-variates when assessing the clinical response to ICI in cancer patients
Can we identify a preferred first-line strategy for sarcomatoid renal cell carcinoma? A network meta-analysis
Background: Combinations based on immune checkpoint inhibitors are the new first-line standard treatment for metastatic renal cell carcinoma. Sarcomatoid renal cell carcinoma (sRCC) has a dismal prognosis but good immunogenicity. Methods: The authors performed a network meta-analysis of Phase III randomized trials of immune checkpoint inhibitor-based combinations versus standard tyrosine kinase inhibitor monotherapy reporting data for sRCC. The endpoints were overall survival, progression-free survival and objective response rate. Results: Five trials comprising 569 sRCC patients (out of a total of 4409 metastatic renal cell carcinoma patients) were included. Nivolumab-cabozantinib was the highest ranking treatment for overall survival (p-value = 88%) and progression-free survival (p-value = 81%). Atezolizumab-bevacizumab had the highest rank for objective response rate (p-value = 80%). Conclusion: Despite some limitations, nivolumab-cabozantinib might be the preferred first-line option for sRCC in terms of efficacy
Upper Tract Urinary Carcinoma: A Unique Immuno-Molecular Entity and a Clinical Challenge in the Current Therapeutic Scenario
: Urothelial carcinoma (UC) is the most frequent malignancy of the urinary tract, which consists of bladder cancer (BC) for 90%, while 5% to 10%, of urinary tract UC (UTUC). BC and UTUC are characterized by distinct phenotypical and genotypical features as well as specific gene- and protein- expression profiles, which result in a diverse natural history of the tumor. With respect to BC, UTUC tends to be diagnosed in a later stage and displays poorer clinical outcome. In the present review, we seek to highlight the individuality of UTUC from a biological, immunological, genetic-molecular, and clinical standpoint, also reporting the most recent evidence on UTUC treatment. In this regard, while the role of surgery in nonmetastatic UTUC is undebated, solid data on adjuvant or neoadjuvant chemotherapy are still an unmet need, not permitting a definite paradigm shift in the standard treatment. In advanced setting, evidence is mainly based on BC literature and retrospective studies and confirms platinum-based combination regimens as bedrock of first-line treatment. Recently, immunotherapy and target therapy are gaining a foothold in the treatment of metastatic disease, with pembrolizumab and atezolizumab showing encouraging results in combination with chemotherapy as a first-line strategy. Moreover, atezolizumab performed well as a maintenance treatment, while pembrolizumab as a single agent achieved promising outcomes in second-line setting. Regarding the target therapy, erdafitinib, a fibroblast growth factor receptor inhibitor, and enfortumab vedotin, an antibody-drug conjugate, proved to have a strong antitumor property, likely due to the distinctive immune-genetic background of UTUC. In this context, great efforts have been addressed to uncover the biological, immunological, and clinical grounds in UTUC patients in order to achieve a personalized treatment
Burnout and Oncology: an irreparable paradigm or a manageable condition? Prevention strategies to reduce Burnout in Oncology Health Care Professionals
: Burnout is a stress-induced occupational related syndrome, characterized by Emotional Exhaustion (EE), feeling of depersonalization (DP) and low sense of professional accomplishment (PA). The aim of this study is to analyse the effectiveness of interventions in decreasing health professionals Burnout as well as work and life-style risk factors. Methods: A survey in Medical Oncology Department in the University Hospital of Parma was conducted using the validated Maslach Burnout Inventory (MBI) and two additional questionnaires exploring lifestyle and work factors. An 8-months intervention involved fortnight meetings by facilitators, incorporated elements of reflection, shared experiences and managing emotions. Six months after the end of the intervention a second survey was performed among the participants using MBI and the same questionnaires mentioned above. Results: EE resulted the most problematic score in Day Hospital: after the 8-month intervention we described a significant decreasing in EE score especially for Day Hospital operators (from 16.7 to 10.9) and a considerable reduction in DP score. In the Oncology Ward a correlation between lack of collaboration among different health categories and DE score was detected; in the Day Hospital the absence of solid working teams was related to higher EE scores. Conclusion: The Oncology professional health care personnel are at the greatest risk of Burnout. Our study in Oncology Department shows that specific intervention should be used to prevent and reduce Burnout. Effective personal health care strategies should be incorporated into routine oncology care to prevent and treat Burnout
Molecular basis and rationale for combining immune checkpoint inhibitors with chemotherapy in non-small cell lung cancer
Immunotherapy has prompted a paradigm shift in advanced non-small cell lung cancer (NSCLC) treatment, by demonstrating superior efficacy to chemotherapy alone both in second- and in first-line setting. Novel insights on molecular mechanisms and regimens to enhance the efficacy of immunotherapy are warranted, as only a minority of patients (˜20%) respond to checkpoint blockade. Taking into account the multiple mechanisms adopted by tumor cells to evade the immune system through cancer immunoediting, the frontline combination of immune checkpoint inhibitors with chemotherapy appears to be a successful strategy as: 1) it enhances the recognition and elimination of tumor cells by the host immune system (immunogenic cell-death), and 2) it reduces the immunosuppressive tumor microenvironment. Remarkably, the immune checkpoint inhibitors pembrolizumab and atezolizumab have already been approved by the FDA in combination with chemotherapy for the first-line treatment of advanced NSCLC and many other chemo-immunotherapeutic regimens have been evaluated as an initial therapeutic approach in metastatic NSCLC. Concurrently, several preclinical studies are evaluating the molecular mechanisms underlying immunomodulation by conventional chemotherapeutic agents (platinum salts, antimitotic agents, antimetabolites and anthracyclines), unraveling drug- and dose/schedule-dependent effects on the immune system that should be exploited to achieve synergistic clinical activity. The current review provides a detailed overview of the immunobiological rationale and molecular basis for combining immune checkpoint inhibitors with chemotherapy for the treatment of advanced NSCLC. Moreover, current evidence and future perspectives towards a better selection of patients who are more likely to benefit from chemo-immunotherapy combinations are discussed
