RESUMO

Salivary gland dysfunction is a common sequel of the hematopoetic progenitor cell transplantation (HPCT) and salivary secretion substantially reduce during conditioning regimen. A gradual flow rate reconstitution could be detected few days after the HPCT. Major salivary glands play a difficult role to diagnosis. Nuclear medicine is a well-documented method and allows an objective, non-invasive and dynamically study of major salivary glands to access individual salivary glands function. Technetium-99mpertechnetate is able to uptake and wash out of salivary glands and 67Ga is used to trace tumors or inflammatory reaction. Twenty HPCT patients were enrolled in this prospective study between March 2002 and November 2003 and were evaluated prior HCPT and following at D+30, D+60 e D+100. Intake and clearance of 99mTc-pertechenate did not show any differences following BMT compared to prior. 67Ga scan showed an increase of inflammatory infiltration following HPCT. No statistically difference was seen in unstimulated salivary flow rate following HPCT. Results suggest an involvement of major salivary glands following HPCT, mainly in submandibular glands. Despite of salivary flow rate did not show any difference the inflammatory infiltrate may be persistent and may be responsible to complaint of dry mouth in these patients
