[Philadelphia chromosome (Ph1) positive acute myelomonocytic leukemia with esophageal cancer: a case report].
A 62-year old male was admitted to our hospital because of fever and dysphagia on November 14, 1987. The peripheral leukocyte count was 174,400/microliters with 93% blasts and bone marrow aspiration showed that 90.4% of nucleated cells were blasts positive for both myeloperoxidase and alpha-naphthylbutyrate esterase. Chromosome analysis revealed a karyotype of 45XY, 9q+, 16q+, -20 and 22q-. Esophageal X-ray and endoscopy showed abnormalities. Esophageal biopsy revealed squamous cell carcinoma. He was diagnosed as having Ph1 positive acute myelomonocytic leukemia (AMMoL, M4) and esophageal cancer. He was treated with BHAC-DMP and intermediate-dose ara-C therapy for leukemia and a complete remission was obtained by March 25, 1988. As treatment for esophageal cancer, radiation therapy (total 4,200 cGy) was given and followed by chemotherapy with CDDP and 5-FU. However he died on April 8, 1988. Autopsy findings showed disseminated invasion of esophageal cancer. Ph1 positive AMMoL associated with esophageal cancer is extremely rare.
