    Squamous cell carcinoma is the most common malignant neoplasm of the oral cavity, and it contributes approximately 90% of all oral malignancies. We present a case of a squamous cell carcinoma of the tongue with rare site of bilateral adrenal metastases on F-FDG PET/CT with response evaluation after chemotherapy. Read More

    Targeting metastasis-initiating cells through the fatty acid receptor CD36.
    Nature 2017 01 7;541(7635):41-45. Epub 2016 Dec 7.
    Institute for Research in Biomedicine (IRB Barcelona), The Barcelona Institute of Science and Technology (BIST), 08028 Barcelona, Spain.
    The fact that the identity of the cells that initiate metastasis in most human cancers is unknown hampers the development of antimetastatic therapies. Here we describe a subpopulation of CD44(bright) cells in human oral carcinomas that do not overexpress mesenchymal genes, are slow-cycling, express high levels of the fatty acid receptor CD36 and lipid metabolism genes, and are unique in their ability to initiate metastasis. Palmitic acid or a high-fat diet specifically boosts the metastatic potential of CD36(+) metastasis-initiating cells in a CD36-dependent manner. Read More

    Tumorigenicity and Validity of Fluorescence Labelled Mesenchymal and Epithelial Human Oral Cancer Cell Lines in Nude Mice.
    Biomed Res Int 2016 13;2016:4897986. Epub 2016 Nov 13.
    Discipline of Oral and Maxillofacial Surgery, Faculty of Dentistry, The University of Hong Kong, Pokfulam, Hong Kong.
    Tumorigenicity and metastatic activity can be visually monitored in cancer cells that were labelled with stable fluorescence. The aim was to establish and validate local and distant spread of subcutaneously previously injected fluorescence transduced human tongue cancer cell lines of epithelial and mesenchymal phenotype in nude mice. A total of 32 four-week-old male athymic Balb/c nude mice were randomly allocated into 4 groups (n = 8). Read More

    Outcomes and prognostic factors for squamous cell carcinoma of the oral tongue in young adults: a single-institution case-matched analysis.
    Eur Arch Otorhinolaryngol 2017 Mar 8;274(3):1683-1690. Epub 2016 Dec 8.
    Département de Radiothérapie, Gustave Roussy, Université Paris-Saclay, Villejuif, 94805, France.
    There is controversy regarding prognosis and treatment of young patients with oral cavity cancer compared to their older counterparts. We conducted a retrospective case-matched analysis of all adult patients younger than 40 years and treated at our institution for a squamous cell carcinoma of the oral cavity. Only non-metastatic adult patients (age >18) with oral tongue cancer were eventually included and matched 1:1 with patients over 40 years of age, at least 20 years older than the cases, with same T and N category and treatment period.

    Neck dissection versus "watchful-waiting" in early squamous cell carcinoma of the tongue our experience on 127 cases.
    Surg Oncol 2016 Dec 21;25(4):401-404. Epub 2016 Sep 21.
    Department of Maxillo-Facial Surgery, University of Naples, "Federico II", Naples, Italy.
    Background: Early oral squamous cell carcinoma (EOSCC) represents about 90% of the oral cancers especially in older males. The etiology is multifactorial, strongly related to tobacco and alcohol abuse, but also infective agents, Human papillomaviruses (HPV16-18), genetic factors and pre-neoplastic lesions seem to be implicated. There is no consensus in the literature for the treatment of early squamous cell carcinoma of the tongue (stages I-II); both an elective neck dissection policy and a watchful-waiting policy have their proponents in the different centers.

    [PSMA-targeted radioligand therapy in prostate cancer].
    Urologe A 2017 Jan;56(1):32-39
    Institut für Nuklearmedizin, Klinikum rechts der Isar, Technische Universität München, Ismaninger Straße 22, 81675, München, Deutschland.
    Radioligand therapy (RLT) directed against prostate-specific membrane antigen (PSMA) enables tumor-specific treatment directed against PSMA-overexpressing prostate cancer cells. Several PSMA ligands such as PSMA-617 or PSMA-I&T have been developed that can be labeled with β‑radiating lutetium-177. These are currently applied in compassionate use programs to treat metastatic castration-resistant prostate cancer (mCRPC). Read More

    Sentinel lymph node biopsy for early oral cancers: Westmead Hospital experience.
