Activation of the phosphatidylinositol-3-kinase (PI3K) pathway is one of the most frequently observed molecular alterations in many human malignancies, including head and neck squamous cell carcinoma (HNSCC). A growing body of evidence demonstrates the prime importance of the PI3K pathway at each stage of tumorigenesis, that is, tumor initiation, progression, recurrence, and metastasis. Expectedly, targeting the PI3K pathway yields some promising results in both preclinical studies and clinical trials for certain cancer patients. However, there are still many questions that need to be answered, given the complexity of this pathway and the existence of its multiple feedback loops and interactions with other signaling pathways. In this paper, we will summarize recent advances in the understanding of the PI3K pathway role in human malignancies, with an emphasis on HNSCC, and discuss the clinical applications and future direction of this field.

Development of high-throughput technologies helped to decipher tumor genomic landscapes revealing actionable molecular alterations. We aimed to rank the level of evidence of recurrent actionable molecular alterations in head and neck squamous cell carcinoma (HNSCC) on the basis of the European Society for Medical Oncology (ESMO) Scale for Clinical Actionability of Molecular Targets (ESCAT) to help the clinicians prioritize treatment. We identified actionable alterations in 33 genes. HRAS-activating mutations were ranked in tier IB because of the efficacy of tipifarnib (farnesyltransferase inhibitor) in HRAS-mutated patients with HNSCC (nonrandomized clinical trial). Microsatellite instability (MSI), high tumor mutational burden (TMB), and NTRK fusions were ranked in tier IC because of PD-1 and TRK tyrosine kinase inhibitors tissue-agnostic approvals. CDKN2A-inactivating alterations and EGFR amplification were ranked in tier IIA because of the efficacy of palbociclib (CDK4/6 inhibitor) and afatinib (tyrosine kinase inhibitor) in these respective molecular subgroups in retrospective analyses of clinical trials. Molecular alterations in several genes, including PIK3CA gene, were ranked in tier IIIA because of clinical benefit in other tumor types, whereas molecular alterations in IGF1R and TP53 genes were ranked in tier IVA and tier V, respectively. The most compelling actionable molecular alterations in HNSCC according to ESCAT include HRAS-activating mutations, MSI, high TMB, NTRK fusions, CDKN2A-inactivating alterations, and EGFR amplification.

PurposeTo determine the efficacy and safety of single-agent sorafenib in patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN) and nasopharyngeal carcinoma (NPC).Patients and MethodsIn this single-arm phase II trial, oral continuous sorafenib was administered in 28-day cycles. Patients had ≤ one line of chemotherapy for recurrent and/or metastatic disease, Eastern Cooperative Oncology Group performance status of ≤ 2, and adequate organ function. At the end of stage 1, efficacy criteria for further accrual were not met, but the study was amended to enroll an additional five patients for paired tumor biopsies.ResultsTwenty-seven and 26 patients were eligible for toxicity and efficacy evaluations, respectively. One patient (3.7%; 95% CI, 0.1% to 19.0%) achieved a partial response. Disease stabilization was maintained in 10 patients (37.0%; 95% CI, 22.4% to 61.2%). The median time to progression was 1.8 months (95% CI, 1.6 to 3.4 months), and median overall survival time was 4.2 months (95% CI, 3.6 to 8.7 months). Sorafenib was well tolerated with few grade 3 and no grade 4 toxicities. Biomarker analysis of paired tumor samples before and after treatment with sorafenib revealed a decrease of pERK in all five patients, with a decrease in Ki67 in four patients, consistent with a disruption of ERK signaling. The antiapoptotic protein Mcl-1 was downregulated in four patients, and there was also evidence of antiangiogenic activity.ConclusionSorafenib was well tolerated and had modest anticancer activity comparable to monotherapy with other targeted agents in this group of patients. Further development in combination with radiation or other agents may be warranted.

6024 Background: Epidermal growth factor receptor (EGFR) pathway inhibition may synergize with anti-PD1 activity by inhibiting macrophage function, increasing antigen presentation, and augmenting T cell responses. Afatinib, an irreversible EGFR tyrosine kinase inhibitor (TKI), has been shown to enhance anti-PD1 activity in in vitro and animal studies. We thus hypothesized that adding afatinib to pembrolizumab may improve the treatment outcomes for patients with recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). Methods: The ALPHA study (NCT03695510) is a single-arm, phase II study with a Simon 2-stage design. Patients with platinum-refractory, recurrent, or metastatic HNSCC are eligible for the study. Afatinib (40mg, oral, daily) and pembrolizumab (200mg, every 3 weeks) are administered to eligible patients. The primary endpoint is the objective response rate (ORR). PD-L1 IHC testing (22C3), comprehensive genomic profiling (CGP, Roche Foundation Medicine One CDx), and targeted multiplexed gene expression profiling (Nanostring nCounter PanCancer Immune Profiling Panel) were applied for biomarker analysis. Results: From JAN 2019 to MAR 2020, 29 patients were enrolled in the study. Age: mean = 53.4 years old; M/F = 27/2. Tumor type: oral cavity: 19; oropharynx: 6, hypopharynx: 2, larynx: 2. PD-L1 TPS > = 50: 7/29 (24.1%), CPS > = 20: 8/29 (27.6%), TMB > 10: 0/25 (0%). The common treatment-related adverse events (AEs; all grades, grade > = 3) were skin rash (22/29, 4/29), diarrhea (17/29, 3/29), paronychia (13/29, 0/29), mucositis (9/29, 1/29), and weight loss (2/29, 0/29). One patient experienced grade 2 pneumonitis. Twelve patients had partial responses to the treatment (12/29, ORR: 41.4%). The data cut-off date was 11FEB2021. The median progression free survival (PFS) was 4.1 (95% confidence interval [CI], 1.9-6.3) months. The median overall survival (OS) was 8.4 (95% CI, 4.1-10.8) months. Patients with high PD-L1 expression had a higher response rate (TPS > = 50: ORR = 0.71, CPS > = 20: ORR = 0.63). EGFR amplification might also predict a higher response rate (ORR: 3/3, 100%). MTAP loss or mutation may predict a poor response to the treatment (ORR: 0/5, 0%), shorter PFS (HR: 4.21, [95% CI: 1.34-13.24], p = 0.014), and shorter OS (HR: 4.20 [95% CI: 1.32-13.41], p = 0.015). Nine patients underwent paired pre-treatment and post-treatment biopsies for gene expression analysis. The mRNA of HLA-A, HLA-B, CXCL13, CXCL9, and CD8A were elevated in the post-treatment biopsies. Three patients underwent post-progression biopsies for CGP study. One patient had a new MTAP mutation. Conclusions: Afatinib can modify tumor microenvironment and increase the clinical response rate in pembrolizumab-based therapy in HNSCC patients. PD-L1, EGFR amplification, and MTAP loss/mutation could be biomarkers for cancer immunotherapy. Clinical trial information: NCT03695510.

Background: Head and neck squamous cell carcinomas (HNSCCs) are particularly aggressive epithelial tumors, that affect more than half a million patients worldwide each year. They represent a multi-factorial group of tumors caused by: alcohol, tobacco, and human papillomavirus (HPV) infections. Over the last ten years the overall 5-year survival rate of HNSCCs remained ~40–50%, inspite of significant improvement in clinical outcome of many tumor types. There are recent data that claim how some of these cells fulfill a suppressive role in the antitumor immune response. It is interesting that new clinical studies demonstrated that HPV (+) HNSCCs were among tumors with the highest immune infiltrates, while HPV (-) presented a reduced number of immune infiltrating cells. Conclusions: Recent researches prove that tumor microenvironment of HNSCC has an important role in tumor progression, aggressivity, metastasis process, in addition to genetic aberrations and molecular alterations of cancer cells. New researches in stromal composition of the HNSCC may be useful in understanding of mechanisms of different responses to therapy, also can be used as a target for therapeutic purposes. Cancer-associated fibroblasts and immune cells, as well as their products found in neck squamous cell carcinoma significantly influence the biological properties of this tumor. Smoking is one of the risk factors of occurrence of most HPV-associated tumors. Promoting smoking cessation should become an essential contributor to the treatment of cancer in all oncologic pathologies. In cases when patients can’t quit smoking completely within the shortest possible period of time, doctors should focus on harm reduction strategies – tobacco harm reduction.
