Ki-1+ Anaplastic Large Cell Lymphoma
0.600 Biomarker disease BEFREE Moreover, ALK expression was confined to the cytoplasm of the tumor cells in each case, supporting the hypothesis that the observed nuclear localization of NPM-ALK in classical ALCL is not the site of oncogenic activity of the ALK kinase. 10381534 1999
Ki-1+ Anaplastic Large Cell Lymphoma
0.600 Biomarker disease BEFREE It is important to separate these from cases of ALK-negative ALCL, which have a poorer prognosis, and cases of primary cutaneous ALCL, which have an excellent prognosis. 10725869 1999

0.600 AlteredExpression disease BEFREE These findings indicate that TFG can provide an alternative to NPM as a fusion partner responsible for activation of the ALK and the pathogenesis of ALCL. 10556217 1999

0.600 Biomarker disease BEFREE Routine tissue biopsies from five cases of ALK-positive ALCL were also strongly positive for phosphotyrosine. 10398126 1999
Ki-1+ Anaplastic Large Cell Lymphoma
0.600 Biomarker disease BEFREE Moreover, their prognosis was excellent and indistinguishable from that of classical t(2;5)-positive tumors, but was clearly different from that of ALK-negative anaplastic large-cell lymphomas. 10552961 1999
Ki-1+ Anaplastic Large Cell Lymphoma

Ki-1+ Anaplastic Large Cell Lymphoma
0.600 Biomarker disease BEFREE In contrast to normal tissues, the two antibodies against the N-terminal portion of NPM labeled the cytoplasm of neoplastic cells, in four ALK-positive ALCL, reflecting their reactivity with NPM-ALK fusion protein, whereas the antibody to the C-terminal NPM epitope labeled only cell nuclei. 9885226 1999
Ki-1+ Anaplastic Large Cell Lymphoma
0.600 AlteredExpression disease BEFREE These cells expressed ALK protein, but, in contrast to t(2;5)-positive ALCL (which show cytoplasmic, nuclear, and nucleolar staining), labeling was restricted to the malignant cell cytoplasm. 10216106 1999
Ki-1+ Anaplastic Large Cell Lymphoma
0.600 GeneticVariation disease BEFREE We conclude that immunohistochemical studies, using antibody ALK1. and FISH for ALK gene rearrangement are equally effective for identifying patients with ALCL who have a favorable clinical outcome. 10555007 1999
