Micrometástase linfonodal em pacientes portadores de adenocarcinoma gástrico submetidos à ressecção radical: correlação de aspectos histopatológicos e importância prognóstica

Vinte e oito pacientes atraves de curvas de sobrevivencia (Kaplan-Meier) sao comparados (log-rank/Cox) quanto a presenca de micrometastase linfonodal, idade; genero; tamanho do tumor; tipo de gastrectomia; profundidade tumoral (pT); invasao linfatica, vascular e perineural; localizacao do tumor no estomago; tipo histologico; acometimento linfonodal (pN); dimensao, localizacao, numero de linfonodos dissecados, acometidos, razao dissecados/acometidos e estadio. Houve pior prognostico nos portadores de micrometastases linfonodais, invasao vascular, perineural, pN2, pN3, estadio III, IV. Maior taxa de micrometastase em linfonodos pequenos, distantes, nas cadeias tres, seis e em pacientes mortos/Lymph nodal micrometastasis in patients with gastric adenocarcinoma submitted to radical resection: correlation of histopathologic aspects and prognostic significance Twenty eight patients were compared through Kaplan-Meier's survival curves. Log-rank/Cox tests were used according to lymph nodal micrometastasis positivity and: age; gender; size, depth (pT) and location of the tumor in stomach wall; gastrectomy extension; limphatic, vascular and perineural invasion; histologic type; lymph node status (pN); stage and lymph node size, location, number of dissected, ressected and dissected/ressected ratio lymph nodes. There was worse prognose in micrometastasis positive lymph node patients related to vascular, perineural, pN2, pN3, III, IV stages. Higher micrometastasis rates were found in small, far, from 3 and 6 chains and passed away lymph nodes patients...
