Major salivary gland damage in allogeneic hematopoietic progenitor cell transplantation assessed by scintigraphic methods.
Salivary gland dysfunction is a common sequela of hematopoietic progenitor cell transplantation (HPCT). The investigation of major salivary gland dysfunction with sodium pertechnetate scintigraphy is a non-invasive method that provides images of the parotid and submandibular glands. In this prospective trial, 20 HPCT patients were submitted to scintigraphic study with 99mTc-pertechenate and 67Ga in order to evaluate the major salivary glands early involvement following HPCT. Major salivary glands were evaluated prior to HCPT as well as at Days +30, +60 and +100 post transplant. Major salivary glands uptake and clearance of 99mTc-pertechenate results did not demonstrate any functional differences between pre- versus post transplant periods. Results of the 67Ga scan revealed inflammatory infiltration following HPCT, primarily in submandibular glands, suggest a persistent involvement of major salivary glands up to Day +100 after HPCT.
