Multiple Metachronous Malignancies One Patient with Three Primary Malignancies

摘要

Development of a primary cancer after treatment of the first with radiotherapy or chemotherapy is well documented, but it is common with hematological malignancies. Variety of reasons are suggested by various researchers, but a conclusive evidence is not yet available. Excepting a few correlations like the tamoxifen therapy and endometrial cancer, angiosarcoma of the breast following radiotherapy, occurrence of other metachronous malignancies seem to be dependent on genetic and environmental factors. A patient with three primary malignancies is presented here.
