    Abstract Background: It is unclear witch regimen is optimal as salvage chemotherapy (SCT) after immune checkpoint inhibitor (ICI) monotherapy for recurrent or metastatic head and neck cancer (RM-HNC).
    Methods: This study enrolled 109 patients. Overall survival (OS) and progression-free survival 2 (PFS2) were compared between patients stratified by SCT regimen.
    Results: Of the 109 patients, 55 underwent SCT after the failure of ICI monotherapy. The OS of these 55 patients was longer than that of patients who did not undergo SCT. The OS and PFS2 were similar between patients treated with paclitaxel (PTX) and cetuximab (Cmab) combination and those treated with PTX monotherapy. The occurrence of irAEs did not impact PFS2 nor OS.
    Conclusions: SCT can improve the survival outcomes of patients with RM-HNC. In addition to PTX and Cmab, PTX monotherapy is also considered an effective SCT regimen. SCT is effective regardless of the presence or absence of irAEs.

    Abstract Comprehensive information on genetic alterations in salivary gland cancer (SGC) is limited. This study aimed to elucidate the genetic and clinical characteristics of patients with SGC using the Center for Cancer Genomics and Advanced Therapeutics (C-CAT) database, a Japanese national genomic database. We analyzed data of 776 patients with SGC registered in the C-CAT database between June 1, 2019, and June 30, 2023. Adenoid cystic carcinoma was the most common histologic type, followed by salivary duct carcinoma (SDC) and adenocarcinoma not otherwise specified. Genetic data of 681 patients receiving FoundationOne® CDx were analyzed. We identified specific features of the combination of TP53 and CDKN2A alterations among the histological types. Specific LYN amplification was mainly detected in carcinoma ex pleomorphic adenoma and myoepithelial carcinoma. For SDC, the frequency of ERBB2 and BRAF alterations were higher in cases with metastatic lesions than in those with primary lesions. Although 28.6% patients were offered recommended treatment options, only 6.8% received the recommended treatments. This study highlights the differences in genetic alterations among the histological types of SGC, with comprehensive genomic profiling tests revealing lower drug accessibility. These findings could contribute to the development of personalized treatment for patients with SGC.

    Abstract We previously reported that regulatory T (Treg) cells expressing CTLA-4 on the cell surface are abundant in head and neck squamous cell carcinoma (HNSCC). The role of expanded Treg cells in the tumor microenvironment of HNSCC remains unclear. In this study, we reveal that the tumor microenvironment of HNSCC is characterized by the high expression of genes related to Treg cells, dendritic cells (DCs), and interleukin (IL)-17-related molecules. Increased expression of IL17A, IL17F, or IL23A contributes to a favorable prognosis of HNSCC. In the tumor microenvironment of HNSCC, IL23A and IL12B are expressed in mature dendritic cells enriched in regulatory molecules (mregDCs). The mregDCs in HNSCC are a migratory and mature phenotype; their signature genes strongly correlate with Treg signature genes in HNSCC. We also observed that IL17A was highly expressed in Th17 cells and exhausted CD8

    Abstract Immune checkpoint inhibitors (ICIs) have become the standard treatment for recurrent or metastatic head and neck cancer (RM-HNC). However, many patients fail to benefit from the treatment. Previous studies have revealed that tumor burden predicts the efficacy of ICIs, but this association remains unclear for RM-HNC. We retrospectively analyzed 94 patients with RM-HNC treated with ICI monotherapy. We estimated the tumor burden using the baseline number of metastatic lesions (BNML) and the baseline sum of the longest diameters of the target lesions (BSLD), and evaluated the association between BNML, BSLD, and standardized uptake value (SUV) and clinical outcomes. The median progression-free survival (PFS) was 7.1 and 3.1 months in the low-BNML and high-BNML groups, respectively (p = 0.010). The median PFS was 9.1 and 3.5 months in the low-BSLD and high-BSLD groups, respectively (p = 0.004). Moreover, patients with high SUVmax levels had worse overall survival (OS) and PFS. BNML, BSLD, and SUVmax are useful prognostic factors in patients with RM-HNC treated with ICIs. Imaging examinations before ICI treatment are recommended to predict the efficacy of ICIs. If the tumor burden is high, cytotoxic anticancer agents may be administered concomitantly with or prior to ICI monotherapy.

    Abstract Primary squamous cell carcinoma of the thyroid (PSCCT) is a rare disease with a poor prognosis. Because of its rarity, there is no established therapeutic regimen in unresectable cases. We report a case of PSCCT treated with weekly paclitaxel (wPTX) for more than 2 years. A 59-year-old woman presented to our hospital with a progressively enlarging neck mass. CT and MRI scans showed a tumor arising from the right lobe of the thyroid, invading the esophagus and trachea, as well as partially surrounding and invading the right common carotid artery. It was deemed unresectable. Biopsy revealed poorly differentiated squamous cell carcinoma. wPTX therapy was initiated. The patient achieved a partial response and is still undergoing treatment 28 months later. Adverse events included grade 3 neutropenia and grade 2 peripheral sensory neuropathy, which were manageable. Long-term wPTX therapy has been effective in this case of unresectable PSCCT.

    Abstract Background: We aimed to define the indications for sentinel lymph node biopsy (SLNB), the third option for cervical treatment in oral cancer with negative cervical lymph nodes.
    Methods: The greatest depth of invasion (DOI) and long diameter (LD) of the primary site were used as exposures. SLN metastasis was considered the outcome.
    Results: In three trials conducted between 2009 and 2016, 158 patients were eligible and reassigned to this study group. The scatterplot based on the respective values of DOI and LD would eventually be divided into three sections. In cases of sections T1, T2, and T3, the proportions of SLN metastasis positivity were 21.3%, 35.3%, and 51.2%, respectively. In certain cases of T1 with 2 mm < DOI ≤ 5 mm and 8 mm < LD ≤ 20 mm, the proportion of SLN metastasis positivity was 40.9%.
    Conclusions: SLNB-navigated or assisted neck dissection can be added as an effective procedure for N0 neck control.

    Abstract The lymph node density (LND) has been reported to be a significant prognostic factor in various types of carcinoma. This study investigated whether the LND is associated with survival in patients with hypopharyngeal squamous cell carcinoma (HPSCC) who have positive lymph nodes without distant metastasis. Forty-six patients who were pathologically diagnosed with HPSCC with positive lymph nodes and without distant metastasis were enrolled in this study. The LND was defined as the ratio of positive lymph nodes to the total number of lymph nodes. An LND of ≥0.09 was found to be significantly correlated with a shorter overall (p = 0.044) and disease-specific (p = 0.019) survival according to a log-rank test. In a multivariate survival analysis using a Cox proportional hazards model adjusted for the pathological T category (pT3-4/pT1-2), pathological N category (pN2/pN1) and positive surgical margin and/or extracapsular spread (presence/absence), both an LND of ≥0.09 and pT3-4 category were associated with significantly shorter overall survival (p < 0.01) and disease-specific survival (p < 0.01). These results suggest that the LND functions as a prognostic factor for HPSCC patients with positive lymph nodes who do not have distant metastasis.

    Abstract Regulatory T (Treg) cells, expressing CD25 (interleukin-2 receptor α chain) and Foxp3 transcription factor, maintain immunological self-tolerance and suppress various immune responses. Here we report a feature of skin Treg cells expanded by ultraviolet B (UVB) exposure. We found that skin Treg cells possessing a healing function are expanded by UVB exposure with the expression of an endogenous opioid precursor, proenkephalin (PENK). Upon UVB exposure, skin Treg cells were expanded with a unique TCR repertoire. Also, they highly expressed a distinctive set of genes enriched in "wound healing involved in inflammatory responses" and the "neuropeptide signaling pathway," as indicated by the high expression of
