Radiology ; 1 Pt 1: Early detection of naso-pharyngeal carcinoma by plasma Epstein-Barr virus DNA analysis in a surveillance program. Association of a distinctive strain of Epstein-Barr virus with gastric cancer.

However, more biological studies using well-defined EBV variants are required, along with cafcinoma detailed NGS comparisons of tumor-derived EBV strains versus those derived from healthy donors. Histopathological classification of nasopharyngeal carcinoma. However, it is the undifferentiated form of nasopharyngeal carcinoma NPC that shows the most consistent worldwide association with EBV. Type 1 I is keratinizing squamous cell carcinoma.

Type 2a II is non-keratinizing squamous cell carcinoma. Da Wikipedia, l’enciclopedia libera. Il monitoraggio della progressione verso il quadro neoplastico richiede l’ esame biopticoalla ricerca delle alterazioni istologiche e citologiche in grado di predire o meno questa evenienza.

La prognosi non sembra differire da quella del carcinoma squamoso [83]. Carcinooma information Article notes Copyright and License information Disclaimer. Istologicamente si distingue per la presenza contemporanea delle cellule tipiche del carcinoma squamoso, a volte con aspetti di cheratinizzazione, mescolate alle strutture a nidi caratteristiche della neoplasia di origine basalecon cellule di piccola dimensione ma con nuclei voluminosi, e talvolta presenza della tipica disposizione periferica delle cellule a palizzata [82].

Once cells have become infected, EBV latent genes provide growth and survival benefits, resulting in the development of NPC. Radiol Clin North Am ; However, epithelial infection may not be the initiating event in virus-associated carcinogenesis, caricnoma tonsils from patients with infectious mononucleosis IM and normal nasopharyngeal biopsies from individuals at high risk of developing NPC lack evidence of epithelial EBV infection [2].

Staging of nasopharyngeal carcinoma is based on clinical and radiologic examination. Whatever the nature of these interactions and the precise role of EBV in the carcinogenic process, there is clearly the opportunity to exploit this association for the clinical benefit of patients. More importantly, EBV DNA levels appear to correlate with treatment response and may predict disease cadcinoma, suggesting nasofarinfeo they may be an independent indicator of prognosis.
