6035 Background: Recent meta-analysis showed that immune checkpoint inhibitors (ICI) have comparable activity in younger vs older patients (pts) (≥65 years (y)). However little is known about efficacy and safety of ICI in elderly pts with relapsed/metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). The aim of this study is to compare efficacy and grade ≥3 immune-related adverse events (irAEs) of ICI in pts ≥70 y with R/M SCCHN to younger pts. Methods: A retrospective study was conducted at 4 French hospitals. Eligibility criteria were pts treated with ICI for R/M SCCHN between September 2014 and December 2018. Clinical and radiological data and outcome were collected from review of medical records. Results: Two hundred twenty six pts were enrolled including 67 pts ≥ 70 y. Median age of elderly pts was 75y (range 70-87). Elderly pts received ICI as first-line treatment in 21% of pts vs 17% in younger pts. In elderly pts, 9% had ECOG of 0, 72% had ECOG of 1 and 15% had ECOG of 2 at ICI initiation vs 34%, 62% and 4% respectively in younger pts (p = 0.0006). In elderly pts, 22% had only loco-regional relapse at ICI initiation, 30% only distant recurrence and 49% had both vs 42%, 32% and 26% respectively (p = 0.0014). Elderly pts received ICI as monotherapy in 73% of pts vs 52% (p = 0.0027). The ORR in elderly pts was 23% vs 13% in younger pts (p = 0.071). After a median follow-up of 16.8 months (m) (range 10.7-23.7), median OS was 9.7m in elderly pts vs 8.7m in younger pts (p = 0.87). Median PFS was 2.7 m in elderly pts vs 1.9 m (p = 0.2). After adjustment for ECOG, type of evolution, number of ICI drugs, time between initial diagnosis and ICI start and number of previous lines, age ≥70 years was significantly associated with a better PFS (HR = 0.66 (95%CI = 0.47;0.93), p = 0.02) but was not significantly associated with OS (HR = 0.91 (95%CI = 0.61;1.34), p = 0.62). Grade ≥3 irAEs occurred in 15% of elderly pts vs 8% of younger pts (p = 0.13). Patients with grade ≥3 irAEs had a significantly higher ORR than pts without Grade ≥3 irAEs (36% vs 14%, p = 0.007). Conclusions: Elderly pts treated with ICI had significantly higher PFS but not OS after adjustment. Grade ≥3 irAEs were associated with significantly higher ORR to ICI in the whole population.

Research Model

Squamous cell carcinoma of oral cavity (OCSCC) accounts for approximately 25% of cases of head and neck squamous cell carcinoma (HNSCC). Tobacco and alcohol consumption are the main risk factors for both cancers. Surgical resection, combined with adjuvant radiotherapy or radiochemotherapy in patients with high risk of relapse, is the key element in management in the initial stages. However, despite the availability of aggressive multidisciplinary treatments, advanced resectable OCSCC carries poor prognosis; only half of the patients are disease-free 5 years after the surgery. Immunotherapy based on the use of immune checkpoint inhibitors has been proven to be effective in a wide variety of tumours, including recurrent and metastatic HNSCC. These positive results resulted in investigations into its effectiveness in earlier stages of the disease with OCSCC emerging as an interesting research model because of the accessible location of the tumours. This article reviews the potential advantages of emerging immunotherapeutic agents [mainly monoclonal antibodies against programmed cell death-1 ( PD-1) immune checkpoint inhibitors] as neoadjuvant treatment for OCSCC at locoregional stages as well as the ongoing clinical trials, challenges in evaluating tumour response, and possible predictive biomarkers of response with highlights regarding the role of oral microbiota as modulators of immune response. The efficacy and safety of anti- PD-1 drugs in these patients have been proven in preliminary trials. If there is a decrease in the relapse rate and an improvement in the overall survival after surgical resection in ongoing trials, preoperative immunotherapy may be established as a treatment option for patients with early stages of the disease.

Checkpoint Inhibitors

Recurrent locally advanced or metastatic head and neck squamous cell carcinoma (HNSCC) is associated with dismal prognosis because of its highly invasive behavior and resistance to conventional intensive chemotherapy. The combination of targeted therapy and conventional chemotherapy has significantly improved clinical outcomes. In recent years, the development of immunotherapies, such as immune checkpoint inhibitors (ICIs), has further increased treatment responses and prolonged survival. However, the limited response rate, risk of immunotherapy-related adverse effects and high cost of immunotherapy make the identification of predictive markers to optimize treatment efficacy a critical issue. Biomarkers are biological molecules that have been widely utilized to predict treatment response to certain treatments and clinical outcomes or to detect disease. An ideal biomarker should exhibit good predictive ability, which can guide healthcare professionals to achieve optimal treatment goals and bring clinical benefit to patients. In this review, we summarized the results of recent and important studies focused on HNSCC ICI immunotherapy and discussed potential biomarkers including their strengths and limitations, aiming to gain more insight into HNSCC immunotherapy in real world clinical practice.
