We herein report the case of an 80-year-old Japanese man with multiple lymph node metastases of lymphoepithelioma-like carcinoma (LELC) from an unknown primary site. The patient was admitted to our hospital due to hoarseness and left supraclavicular lymphadenopathy. Contrast-enhanced whole-body computed tomography revealed mediastinal, left supraclavicular, and left axillary lymphadenopathy. A left supraclavicular lymph node biopsy was performed and the specimen was consequently diagnosed as exhibting LELC. The patient's Eastern Cooperative Oncology Group performance status was 0, therefore he was started on chemotherapy with carboplatin and pemetrexed. His lymph nodes responded well to four cycles of chemotherapy without any intolerable adverse effect.

The expression of CCL17 and potential prognostic value on tumor immunity in thyroid carcinoma based on bioinformatics analysis.

Although CCL17 has been reported to exert a vital role in many cancers, the related studies in the thyroid carcinoma have never reported. As a chemokine, CCL17 plays a positive role by promoting the infiltration of immune cells into the tumor microenviroment (TME) to influence tumor invasion and metastasis. Therefore, this study is aimed to investigate the association of CCL17 level with potential prognostic value on tumor immunity in the thyroid carcinoma (THCA) based on the bioinformatics analysis.

There is a pressing need to improve risk stratification and treatment selection for HPV-negative head and neck squamous cell carcinoma (HNSCC) due to the adverse side effects of treatment. One of the most important prognostic features is lymph nodes involvement. Previously, we demonstrated that tumor formation in patient-derived xenografts (i.

Antibody-mediated protection against pathogens is crucial to a healthy life. However, the recent SARS-CoV-2 pandemic has shown that pre-existing comorbid conditions including kidney disease account for compromised humoral immunity to infections. Individuals with kidney disease are not only susceptible to infections but also exhibit poor vaccine-induced antibody response.
