Uso da 99mTc-Timina na identificação de metástases de tumor venéreo transmissível canino com apresentação cutânea

Abstract: O tumor venéreo transmissível canino (TVTC) é descrito na literatura como raramente metastático. Entretanto, métodos acurados para verificação dessa afirmativa não estão disponíveis na rotina veterinária. Neste trabalho utilizou-se a cintilografia com 99mTc-Timina para avaliar a disseminação do TVTC com apresentação cutânea. Houve captação da 99mTc-Timina nos três casos de TVTC estudados. A cintilografia com 99mTc-Timina é uma técnica não-invasiva e promissora para a avaliação do grau de disseminação tumoral e… Show more

“…In our study, thymine was labeled with 99m Tc, proving to be effective for the detection of primary tumors and metastases. 32,37 In light of our results, we suggest the expansion of scintigraphy use for metastatic lesion evaluation in the thoracic and abdominal cavities due to its sensitivity to early neoplasia stage detection when compared against other available imaging methods. One additional advantage of the scintigraphy is that it exempts particular incidences to acquire images when compared to X-ray examination that demands at least three projections (right-lateral, left-lateral, ventrodorsal or dorsoventral) for an adequate sensitivity.…”

“…Nonetheless, 99m Tc scintigraphy labeling is more sensitive than radiography and computed tomography for skeletal imaging, and metastatic neoplasia. 32,33 Moreover, scintigraphy is applied to assess thyroid dysfunctions, 34 renal perfusion, 35 portosystemic shunts, 23 and gastric emptying time experiments 36 in cats. In our study, thymine was labeled with 99m Tc, proving to be effective for the detection of primary tumors and metastases.…”

“…Conforme relatos de alguns autores o TVT de ocorrência natural evolui à regressão quando estabelecido em cães imunologicamente competentes (Liao et al 2003;Park et al 2006). Daleck e colaboradores (2009), relatam que a pele é o principal sítio de metástase, ocorrendo também casos que envolvem a musosa anal e perineal, o tecido subcutâneo, fígado, baço, rins, tecido muscular, língua e linfonodos (Castelo-Branco et al 2008). Pode ocorrer a extensão do tumor nasal para os seios maxilares e faringe, da vagina para a cérvix e corpo do útero e também se instalando no globo ocular.…”
