PURPOSE: We aim to delineate the clinical characteristics of patients with primary intracranial solitary plasmacytoma (PISPC) and prognostic factors for their outcomes.
METHODS: This study retrospectively reviewed 17 patients with PISPC from our center and an additional 70 cases of PISPC published previously to analyze outcome predictors.
RESULTS: The entire cohort included 38 (43.7%) males and 49 (56.3%) females with a mean age of 54 years. Skull base tumors were found in 49 (56.3%) patients. Gross total resection (GTR) was achieved in 31 (35.6%) patients. Postoperative adjuvant treatments, including radiotherapy (RT) alone, chemotherapy (CMT) alone, and RT + CMT were administered in 49 (56.3%) patients, 3 (3.5%) patients, and 16 (18.4%) patients, respectively. After a median follow-up of 24 (mean 42.4) months, the 5-year disease progression-free survival (PFS), recurrence-free survival (RFS), multiple myeloma (MM)-free survival (MMFS), and overall survival (OS) were 52.9%, 76.2%, 69.6%, and 76.1%, respectively. Multivariate analysis unveiled that a skull base tumor location (HR 2.395, p = 0.040) and no RT (HR 3.115, p = 0.004) were negative prognostic factors for PFS, no RT (HR 10.526, p = 0.003) for RFS, each 1-year increase in age (HR 1.039, p = 0.049) for MMFS, and increasing age (HR 1.052, p = 0.043) and CMT (HR 6.022, p = 0.005) were risk factors for OS. However, GTR did not benefit the aforementioned outcomes.
CONCLUSION: For patients with presumed PISPC, a biopsy followed by RT is recommended for skull base PISPC. However, the role of CMT is still not clear. Our findings need to be verified in a larger prospective cohort in the future. Systematic review registration number CRD42018098782.
