Additionally, R/M HNSCC patients treated with pembrolizumab plus chemotherapy had significantly prolonged OS compared to the cetuximab with chemotherapy group. Although neither baseline CD8+ T cell infiltration status nor PD-L1 expression level correlated with overall response, there was a trend in which greater CD8+ T cells infiltrated patients tended to show MPR. Any pTR was seen in 44% and pTR-2 was seen in 22% of patients.

Several landmark trials established the clinical benefit of using cisplatin-based chemoradiotherapy after surgery for locally advanced, high-risk HNSCC patients (3, 4). Tumour Regression in Non-Small-Cell Lung Cancer Following Neoadjuvant Therapy. These trials led to US Food and Drug Administration (FDA) approval of the use of anti-PD-1 (nivolumab and pembrolizumab) for second-line for recurrent and metastatic HNSCC patients who had already experienced platinum-based therapies (31). A trial done by Tata Memorial Centre is included that randomized patients with mostly oral tongue carcinoma to elective neck dissection at the time of primary cancer surgery or watchful waiting with therapeutic neck dissection for nodal relapse.

In this trial, only one patient showed a grade III AE (rash) while no patients had grade IV AE, consistent with the safety and tolerability of neoadjuvant immunotherapy (75). Privacy These encouraging findings have led to numerous ongoing studies testing combinations to improve CPI response rates and also testing these agents in other settings. The BATTLE-2 Study: a biomarker-integrated targeted therapy study in previously treated patients with advanced nonsmall-cell lung cancer. A meta-analysis by Pignon et al. Ferrarotto R, Bell D, Rubin ML, Hutcheson KA, Johnson JM, Goepfert RP, et al. The current mainstay of advanced head and neck squamous cell carcinoma (HNSCC) treatment remains surgery and radiotherapy with/without conventional chemotherapy. Neoadjuvant immunotherapy has the potential to enhance clinical outcomes by increasing anti-tumor immune responses in the presence of abundant tumor-derived antigen in an immune microenvironment that has not been exposed to previous therapy. The CD8+ T cell data was correlated with preclinical models, where anti-PD-1 and anti-CTLA4 combinatorial therapy increased tumor-infiltrating CD8+ T cells (71). Pathological Response After Neoadjuvant Chemotherapy in Resectable Non-Small-Cell Lung Cancers: Proposal for the Use of Major Pathological Response as a Surrogate Endpoint. This is multi-institutional trial enrolled 92 patients and 76 patients were evaluable for DFS. IC resulted in larynx preservation but did not contribute to improved survival. The landmark phase III CheckMate 141 trial resulted in the approval of nivolumab in the R/M second-line HNSCC setting (12). In the neoadjuvant immunotherapy context, immune-modified RECIST (imRECIST) criteria have been proposed (56). Successes and failures: what did we learn from recent first-line treatment immunotherapy trials in non-small cell lung cancer? Readers are encouraged to refer to the full manuscript of these trials for a greater understanding. Pathologic treatment effect (PTE) is another similar scale, which is evaluated by the area showing fibrosis or lymphohistiocytic inflammation divided by total tumor area (65). Given that the genomic analyses of HNSCC has not identified widely shared oncogenic driver mutations but shows relatively high TMB (49, 50), the relationship between TMB and response to CPIs is promising. Discordant Responses Between Primary Head and Neck Tumors and Nodal Metastases Treated With Neoadjuvant Nivolumab: Correlation of Radiographic and Pathologic Treatment Effect. Study 19 [28, 29] used olaparib against placebo and demonstrated a PFS of 11.2months in BRCA-mutated patients compared with 4.3months for wild-type patients (hazard ratio, 0.18; P<0.0001). 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. 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.
