Abstract
This study was to investigate clinical features and prognosis of duplex primary malignant neoplasms involving chronic myeloid leukemia (CML-DPMNs). Clinical data of thirteen CML-DPMN patients who were admitted to the First Hospital of Jilin University from May 2008 to December 2018 were collected and retrospectively analyzed. Female patients (9/13) were predominant in this cohort study. Nine patients were metachronous DPMNs (metachronous duplex primary malignant neoplasms involving chronic myeloid leukemia) with 5 years median interval time from primary malignancy to secondary malignancy. The other 4 patients were diagnosed as synchronous CML-DPMNs. Seven of the metachronous duplex primary malignant neoplasms involving chronic myeloid leukemia suffered from CML following many years of comprehensive anti-cancer therapy. Two of CML-MDPMN patients had invasive ductal carcinoma of breast after many years of treatment with imatinib. There was no difference between treatment-related CML group and non-treatment-related CML group in regard as the gender, age, white blood cell count, hemoglobin level, platelet count, and risk level. The median overall survival time of these thirteen patients with CML-DPMNs was not reached. In conclusion, female patients are more likely to suffer from the CML-DPMNs in the present article. Overall survival time of patients with DPMNs involving CML could be promising if timely and effective treatment therapy is adopted.
