Characterization of Human γδ T Lymphocytes Infiltrating Primary Malignant Melanomas
2012
T lymphocytes are often induced naturally in melanoma patients and infiltrate tumors. Given that gamma delta T cells mediate antigen-specific killing of tumor cells, we studied the representation and the in vitro cytokine production and cytotoxic activity of tumor infiltrating gamma delta T cells from 74 patients with primary melanoma. We found that gamma delta T cells represent the major lymphocyte population infiltrating melanoma, and both V delta 1(+) and V delta 2(+) cells are involved. The majority of melanoma-infiltrating gamma delta cells showed effector memory and terminally-differentiated phenotypes and, accordingly, polyclonal gamma delta T cell lines obtained from tumor-infiltrat…
Reliability of the pre-operative imaging to assess neck nodal involvement in oral cancer patients, a single-center study
2022
Background: Primary sites for the metastasis of oral cancer are the cervical lymph nodes. Although there has been considerable technical advancement in the radiological imaging, capability to recognize all metastatic lymph nodes pre-operatively has remained as a challenge. Thus elective neck dissection (END) has remained as reli-able practice to treat cervical lymph nodes. This study evaluated the accuracy of pre-operative imaging in pre-operative diagnostics of cervical lymph node status using computed tomography or magnetic resonance imaging in patients with oral squamous cell carcinoma (OSCC). We have also considered the reasons for the difficulties to recognise metastatic nodes in cervi…
