Tumores malignos de la glándula parótidaCancer of the parotid gland tumores malignos de parótida en nuestro estudio fue del 56% a los 5 años, con un 68%. However, the prognosis depends on factors other than histology and tumor extension. Seguimiento de 19 pacientes con carcinomas de parótida distintos de.
Therefore, transketolase upregulation in tumor progression seems very likely. However, the expression was not associated with relapse risk or survival. In other studies, tumors with an aggressive clinical course were investigated e. With the background of the importance of the PPP in nucleic acid ribose synthesis, our findings fit with the slow growth of ACC.
The glycolytic M2 pyruvate kinase isoenzyme M2PK plays a key role by channelling glucose carbons either into synthetic processes or towards glycolytic energy production, the former reactions being catalyzed by the dimeric form of M2PK, the latter by its tetrameric form.
The dimeric form of M2PK is characteristic for tumor cells [ 12 ] resulting in an accumulation of glycolytic metabolites, which are canalized into synthetic processes such as amino acid production or nucleic acid synthesis via the pentosephosphate cycle.
Despite non-significant results, similar to other tumors a lower degree of M2PK expression tends to be an unfavorable parameter for prognosis. Interestingly, in our cohort elderly showed a lower expression, but this result was not found associated with another relapse risk in this subgroup.
The expression and functionality of glucose transporters GLUT in tumors is probably related to a number of factors. In this context, the role of oncogenes and tumor hypoxia has generated a considerable interest [ 20 ]. In squamous cell carcinomas and other malignancies, hypoxia induces a higher expression of GLUT [ 21 ].
