ABSTRACT
Objective:
To compare the clinical characteristics and survival outcomes of multiple myeloma (MM) with second primary malignancies (SPMs) and MM secondary to malignancies.Methods:
The clinical data of MM patients diagnosed and treated in Beijing Chaoyang Hospital, Capital Medical University from January 2002 to January 2021 were included. The patients were divided into two groups MM with SPMs group and MM secondary to malignancies group. The gender, age at first diagnosis, classification, stage, type of combined malignant tumor and the treatment were analyzed. The clinical characteristics and survival differences were compared between the two groups.Results:
There were 20 patients in the MM with SPMs group, 9 males and 11 females, aged [M(Q1,Q3)] 61.5(56.8, 68.0)years, and the overall survival (OS) was 49.5(32, 58) months, while the time to death from secondary tumor was 12(4,21)months. There were 29 patients in the MM secondary to malignancies group, 13 males and 16 females, aged 64.0(57.0, 71.0)years, and the OS was 97(61, 171) months, while the time to death from secondary MM was 32(18, 47) months. The time from patients diagnosed with MM to SPMs was 37(18, 50) months, which was significantly earlier than that of MM secondary to malignancies [53(31,117) months](P=0.016). The type of tumor was also different between the two groups (P<0.001). In the group of MM with SPMs, the most common type of SPMs was hematopoietic malignancies (12/20, 60.0%), whereas in the group of MM secondary to malignancies, MM was most often secondary to genitourinary malignancies (13/29, 44.8%) (P<0.001).Conclusions:
Both MM with SPMs and MM secondary to malignancies can affect the survival of patients. Secondary hematological malignancies account for a high proportion of the second tumors in MM patients, while genitourinary malignancies account for a high proportion of malignant tumors associated with MM.
