Pembrolizumab-based first-line treatment for PD-L1-positive, recurrent or metastatic head and neck squamous cell carcinoma: a retrospective analysis.

Background: The KEYNOTE-048 trial showed that pembrolizumab-based first-line treatment for R/M HNSCC led to improved OS in the PD-L1 CPS ≥ 1 population when compared to the EXTREME regimen. However, the R/M HNSCC real-world population is generally frailer, often presenting with multiple comorbidities, worse performance status and older age than the population included in phase III clinical trials.

Methods: This is a retrospective, single-centre analysis of patients with R/M HNSCC treated with pembrolizumab-based first-line treatment.

The Impact of Drug-Drug Interactions on the Toxicity Profile of Combined Treatment with BRAF and MEK Inhibitors in Patients with BRAF-Mutated Metastatic Melanoma.

Background: BRAF and MEK inhibition is a successful strategy in managing BRAF-mutant melanoma, even if the treatment-related toxicity is substantial. We analyzed the role of drug-drug interactions (DDI) on the toxicity profile of anti-BRAF/anti-MEK therapy.

Methods: In this multicenter, observational, and retrospective study, DDIs were assessed using Drug-PIN software (V 2/23).

A network approach to define the predictive role of immune profile on tumor response and toxicity of anti PD-1 single agent immunotherapy in patients with solid tumors.

Background: The immune profile of each patient could be considered as a portrait of the fitness of his/her own immune system. The predictive role of the immune profile in immune-related toxicities (irAEs) development and tumour response to treatment was investigated.

Methods: A prospective, multicenter study evaluating, through a multiplex assay, the soluble immune profile at the baseline of 53 patients with advanced cancer, treated with immunotherapy as single agent was performed.

Immune-related toxicity and soluble profile in patients affected by solid tumors: a network approach.

Background: Immune checkpoint inhibitors (ICIs) have particular, immune-related adverse events (irAEs), as a consequence of interfering with self-tolerance mechanisms. The incidence of irAEs varies depending on ICI class, administered dose and treatment schedule. The aim of this study was to define a baseline (T0) immune profile (IP) predictive of irAE development.

Molecular profiling of male breast cancer by multigene panel testing: Implications for precision oncology.

Introduction: Compared with breast cancer (BC) in women, BC in men is a rare disease with genetic and molecular peculiarities. Therapeutic approaches for male BC (MBC) are currently extrapolated from the clinical management of female BC, although the disease does not exactly overlap in males and females. Data on specific molecular biomarkers in MBC are lacking, cutting out male patients from more appropriate therapeutic strategies.

The role of immune profile in predicting outcomes in cancer patients treated with immunotherapy.

Background: Despite the efficacy of immunotherapy, only a small percentage of patients achieves a long-term benefit in terms of overall survival. The aim of this study was to define an immune profile predicting the response to immune checkpoint inhibitors (ICIs).

Methods: Patients with advanced solid tumors, who underwent ICI treatment were enrolled in this prospective study.

Genomic and Immune Approach in Platinum Refractory HPV-Negative Head and Neck Squamous Cell Carcinoma Patients Treated with Immunotherapy: A Novel Combined Profile.

Introduction: Only a minority of patients with platinum refractory head and neck squamous cell carcinoma (PR/HNSCC) gain some lasting benefit from immunotherapy.

Methods: The combined role of the comprehensive genomic (through the FoundationOne Cdx test) and immune profiles of 10 PR/HNSCC patients treated with the anti-PD-1 nivolumab was evaluated. The immune profiles were studied both at baseline and at the second cycle of immunotherapy, weighing 20 circulating cytokines/chemokines, adhesion molecules, and 14 soluble immune checkpoints dosed through a multiplex assay.

Anti-PD-1 and Anti-PD-L1 in Head and Neck Cancer: A Network Meta-Analysis.

Objective: The monoclonal antibodies anti-programmed death protein-1 (anti-PD-1) nivolumab and pembrolizumab are the first immune checkpoint inhibitors (ICIs) approved for treatment of recurrent/metastatic head and neck carcinoma R/M HNSCC in first line and in platinum refractory disease. This network meta-analysis aims to investigate the efficacy of anti-PD-1- anti-PD-L1-based therapy in R/M HNSCC cancer patients through a systematic review of the literature to provide support for evidence-based treatment decisions. In particular, the effectiveness of ICIs for R/M HNSCC is analyzed according to the different mechanisms of action of the check-points inhibitory drugs in different subgroups of patients.

The Role of Soluble LAG3 and Soluble Immune Checkpoints Profile in Advanced Head and Neck Cancer: A Pilot Study.

Unresectable recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC) has a very poor prognosis. Soluble immune checkpoints (sICs) are circulating proteins that result from the alternative splicing of membrane proteins and can modulate the immune response to cancer cells. The aim of our pilot study was to determine the possible role of a comprehensive evaluation of sICs in the classification of prognosis and response to treatment in patients with advanced disease.

Weekly chemotherapy as first line treatment in frail head and neck cancer patients in the immunotherapy era.

Objective: First-line therapy for metastatic squamous cell carcinoma of the head and neck (R/M HNSCC) has been revolutionized by the introduction of anti-checkpoint monoclonal antibodies, which have shown a significant improvement in overall survival (OS) gaining approval in a first line setting. Efficacy and safety of first-line weekly chemotherapy, compared to 3-weeks treatment, was retrospectively evaluated in a frail patient population with R/M HNSCC with the aim to evaluate its role as part of a personalized first-line approach.

Methods: A total of 124 patients with locally incurable R/M HNSCC receiving weekly (21) or three-weekly (103) chemotherapy plus cetuximab in a first line setting from December 2010 to September 2020 were retrospectively reviewed.

Standard of Care and Promising New Agents for the Treatment of Mesenchymal Triple-Negative Breast Cancer.

The pathologic definition of triple negative breast cancer (TNBC) relies on the absence of expression of estrogen, progesterone and HER2 receptors. However, this BC subgroup is distinguished by a wide biological, molecular and clinical heterogeneity. Among the intrinsic TNBC subtypes, the mesenchymal type is defined by the expression of genes involved in the epithelial to mesenchymal transition, stromal interaction and cell motility.

The role of opioids in cancer response to immunotherapy.

Background: The response to immunotherapy can be impaired by several factors including external intervention such as drug interactions with immune system. We aimed to examine the immunomodulatory action of opioids, since immune cells express opioid receptors able to negatively influence their activities.

Methods: This observational, multicenter, retrospective study, recruited patients with different metastatic solid tumors, who have received immunotherapy between September 2014 and September 2019.

A New Medical Record Proposal to the Prognostic Risk Assessment for MRONJ in Oncologic Patients: "Sapienza Head and Neck Unit" Proposal.

Medication-related osteonecrosis of the jaw (MRONJ) is an adverse event associated with antiresorptive and antiangiogenic drugs. The use of these drugs in the treatment of cancer patients with bone metastasis is necessary and standardized in the literature. A multidisciplinary approach for the patient's management is strongly recommended.

Myocardial Metastasis of Tongue Cancer: A Rare Localization.

BACKGROUND Cardiac metastases of head and neck tumors are extremely rare, and antemortem diagnosis is even rarer. In most cases, patients show symptoms or electrocardiographic abnormalities and expected survival is considerably low. CASE REPORT A 72-year-old man was admitted to our cardiology ward with suspected endocarditis 2 months after a right hemiglossectomy for a squamous cell carcinoma.

Primary squamous cell carcinoma of major salivary gland: "Sapienza Head and Neck Unit" clinical recommendations.

Primary squamous cell carcinoma of salivary gland (SCG) is an extremely rare type of malignant salivary gland tumor, which in turn results in scarcity of data available regarding both its treatment and associated genetic alterations. A retrospective analysis of 12 patients with primary SCG was conducted, along with analysis of the association between treatment, clinical/pathological characteristics, and outcomes. Most patients (8) were staged IVa, with the majority of them (10) having G3 fast growing cancer.

Tissue Immune Profile: A Tool to Predict Response to Neoadjuvant Therapy in Triple Negative Breast Cancer.

Pathological complete response (pCR) after neoadjuvant chemotherapy (NACT) can predict better survival outcomes in patients with early triple negative breast cancer (TNBC). Tumor infiltrating lymphocytes (TILs), Programmed Death-Ligand 1 (PD-L1), and Cluster of Differentiation 73 (CD73) are immune-related biomarkers that can be evaluated in the tumor microenvironment. We investigated if the contemporary expression of these biomarkers combined in a tissue immune profile (TIP) can predict pCR better than single biomarkers in TNBC.

Induction chemotherapy in nonlaryngeal human papilloma virus-negative high-risk head and neck cancer: a real-world experience.

The role of induction chemotherapy in the multidisciplinary treatment of locally advanced, nonlaryngeal high-risk human papilloma virus (HPV)-negative head and neck squamous cells carcinoma (HNSCC) is uncertain in terms of overall survival (OS). The primary objective of this study was to identify possible predictive factors of survival and outcome in patients with HNSCC who were treated with induction chemotherapy. Fifty-nine patients with stage IVa/b HPV-negative non-laryngeal HNSCC (mostly originating from the oral cavity) who underwent induction chemotherapy at Policlinico Umberto I were reviewed.

Efficacy and Tolerability of Selective Internal Radiotherapy With Yttrium-90 as Consolidation Treatment After Chemotherapy in Metastatic Colorectal Cancer.

Background: Selective internal radiotherapy (SIRT) with yttrium-90 (Y-90)-labeled resin microspheres may have a role in consolidating the response to chemotherapy in patients with metastatic colorectal cancer unamenable to resection after assessment of the best response to first-line chemotherapy.

Patients And Methods: This was a retrospective analysis of outcomes in patients who had received SIRT as consolidation therapy after one or more lines of chemotherapy. Eligible patients were 18 years or older, had confirmed colorectal liver metastases, and had disease unsuitable for surgical resection or local ablation with curative intent.

Tryptophan Catabolism as Immune Mechanism of Primary Resistance to Anti-PD-1.

Clinical trials showed that only a subset of patients benefits from immunotherapy, suggesting the need to identify new predictive biomarker of resistance. Indoleamine-2,3-dioxygenase (IDO) has been proposed as a mechanism of resistance to anti-PD-1 treatment, and serum kynurenine/tryptophan (kyn/trp) ratio represents a possible marker of IDO activity. Metastatic non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), and head and neck squamous cell carcinoma (HNSCC) treated with nivolumab as second-line treatment were included in this prospective study.

The 5-Ws of immunotherapy in head and neck cancer.

The immune checkpoint inhibitors, a class of drugs able to block immune suppressive pathways in order to prime an anticancer immunity, revolutionized standard of care in platinum-refractory recurrent and/or metastatic head and neck carcinoma (R/M HNSCC). The PD-1/ PD-L1 axis is involved in the genesis, maintenance and progression of HNSCC and represents the target of checkpoint inhibitors. HNSCC is an immunosuppressive disease with a high inflammatory component in tumor microenvironment.
