Repetitive response to gemcitabine that led to curative resection in cholangiocarcinoma
This study reports a case of unresectable intrahepatic mass-forming cholangiocarcinoma which showed a dramatic response to gemcitabine that led to curative resection and a long-term survival of more than five years. Six and five cycles of gemcitabine monotherapy were administered separately over a three-year period and a radical excision was performed at 4.5 years after diagnosis. This case indicates the role of gemcitabine as a neoadjuvant chemotherapeutic agent for cholangiocarcinoma and guarantees a randomized controlled prospective study.
This is the first report of e6a2 and e1a2 BCR/ABL1 positive chronic myeloid leukemia (CML) with cryptic deletions of the 5'ABL1 and 3'BCR in separate clones which differ in genomic regions of the deleted der(9). Both deletions were detected throughout monitoring. Imatinib mesylate stabilized this CML with rare genetic aberrations for a relatively long time.
