Tumors with both PD-L1 and PD-L2 expression responded better than tumors with only PD-L1 expression, indicating that combinatorial scoring may be an attractive approach. 2014;371(3):21323. Despite this multi-modality treatment, advanced human papillomavirus (HPV)-negative HNSCC shows poor prognosis. Results from the CLEOPATRA trial in the metastatic setting of the same treatment have produced remarkable results [25]; the same combination produced a 56.5-month median OS compared with 40.8months achieved with trastuzumab and docetaxel alone, showing an increase of 15.7months to OS in the pertuzumab group.

Positive results from this study established the application of anti-PD-1 for R/M HNSCC treatment, and proved the existence of actionable, efficient anti-cancer immunity in HNSCC tumors. In addition to ongoing Phase II trials, KEYNOTE-689 is an international phase III study (NCT03765918) where surgically resectable locally advanced HPV-negative HNSCC patients are randomized to receive upfront surgery with SOC adjuvant treatment or neoadjuvant pembrolizumab (two doses) followed by surgery and SOC adjuvant treatment with pembrolizumab (76).

Furthermore, although distinct tumor-suppressor mutations including TP53, CDKN2A, NOTCH have been reported in HNSCC, cancer-promoting driver oncogenic mutations have not been detected (911), which makes it challenging to apply molecular targeted therapies.

However, some immunological therapeutic effects can induce pseudo-progression or development of new lesions because of infiltration of immune cells into the primary tumor or lymph nodes, which makes it difficult to evaluate the treatment efficacy only with radiographical information (57). Considering the high-frequency of severe adverse events and lack of significant effect OS prolongation with induction chemotherapy, neoadjuvant immunotherapy thus represents an attractive option for advanced HNSCC treatment. In addition, as other checkpoints are testing, further improvements in pathologic responses and clinical outcomes are expected.

Differences in T-Cell Infiltrates and Survival Between HPV+ and HPV- Oropharyngeal Squamous Cell Carcinoma. PD-L1 expression in tumor cells and immune cells remains the most widely used biomarker in HNSCC and other cancers (40, 41). Combinations of chlorambucil with an anti-CD2O monoclonal antibody, such as rituximab, ofatumumab or obinutuzumab, are now the standard of care in patients unsuited to receive fludarabine, cyclophosphamide and rituximab [34,35,36].

Precision medicine needs randomized clinical trials. Despite these efforts to improve clinical prognosis, the five-year survival rate of locally advanced stage III/IV HNSCC patients is still sub-optimal [53% in postoperative CCRT treated patients (7)], and half of advanced patients show recurrence within three years (8). Similarly, the Keynote-040 randomized phase III trial compared the efficacy of pembrolizumab (anti-PD-1) versus SOC (methotrexate, docetaxel, or cetuximab) (13) for R/M HNSCC patients after platinum-containing treatment. The current results of anti-PD-1 therapy with pembrolizumab or nivolumab monotherapy in melanoma indicated a median overall survival (OS) of approximately 2years, but the combination of anti-PD-1 and anti-CTLA-4 (nivolumab with ipilimumab) was shown to be superior in terms of progression-free survival (PFS) and OS (Table1) [11,12,13,14,15]. doi: 10.1200/JCO.2014.58.6412, 3.

A potential shortcoming with the upfront use of ibrutinib includes cost and indefinite treatment course [37]. From a clinical standpoint, he is actively involved in the management and treatment of patients with hematological malignancies and, particularly, those suffering from lymphoproliferative disorders. These data together support further investigation in Phase III trials such as KEYNOTE-689 to define evidence for survival benefit and identify high-risk patients who may benefit from this approach. A meta-analysis which examined the results of clinical trials including Checkmate 141, KEYNOTE-012, KEYNOTE-055 showed that HPV infection status was associated with the response rate to anti-PD-1 treatment independently of PD-L1 expression and TMB in HNSCC (45).
