A complex t(15;22;17)(q22;q11.2;q21) variant of APL
The present study described an extremely rare case of acute promyelocytic leukemia (APL) characterized by a complex three‑way (15;22;17)(q22;q11.2;q21) translocation. Acute promyelocytic leukemia (APL) is a specific subtype of acute myeloid leukemia with distinctive clinical and therapeutic characteristics. Besides being characterized by the t(15;17)(q22;q12) translocation, this subtype is also notable for its response to all-trans-retinoic acid (ATRA) treatment. APL is highly responsive to a combination of ATRA and chemotherapeutic agents, achieving over 90 % complete remission rates and over 80 % long-term remission rates. In this case, a 79-year-old male patient presented with complaints of weakness, fatigue, and petechial rash, with no other significant medical history except for diabetes mellitus and hypertension. Conventional cytogenetic methods, dual-color dual-fusion, and dual-color break-apart fluorescent in situ hybridization techniques together identified the t(15;22;17) translocation. RT-PCR analysis was performed for expression of PML/RARA fusion transcripts. The patient, diagnosed with APL, exhibited a complete response to all-trans retinoic acid (ATRA) and idarubicin treatment. In this paper, we present the second documented case of t(15;22;17) and explore the remarkable remission observed following treatment with All-Trans Retinoic Acid (ATRA).
期刊介绍：
The aim of Cancer Genetics is to publish high quality scientific papers on the cellular, genetic and molecular aspects of cancer, including cancer predisposition and clinical diagnostic applications. Specific areas of interest include descriptions of new chromosomal, molecular or epigenetic alterations in benign and malignant diseases; novel laboratory approaches for identification and characterization of chromosomal rearrangements or genomic alterations in cancer cells; correlation of genetic changes with pathology and clinical presentation; and the molecular genetics of cancer predisposition. To reach a basic science and clinical multidisciplinary audience, we welcome original full-length articles, reviews, meeting summaries, brief reports, and letters to the editor.
