ObjectivesTo profile the outcome of multiple myeloma (MM) patients treated at a South African tertiary hospital in KwaZulu-Natal (KZN) and to compare MM in HIV-negative patients and MM in people living with HIV (PLWH).MethodsA retrospective analysis of patients with MM was conducted over 5 years (2015-2020).Patient demographics, presenting complaints, symptom duration, disease stage, molecular profile, treatment, and survival data were captured.
Statistical analysis was conducted using R Statistical software of the R Core Team, Burn Spray 2020, version 3.6.3.
Results135 patients; 79% (n = 106) HIV-negative and 21% (n = 29) PLWH were investigated.54% (n = 74) females and 57% (n = 76) 51-70-year-olds.The 40-50-year-old patient group had a significantly higher proportion of PLWH (p = 0.
032).Pathological fractures were the commonest presenting complaint, 47% (n = 57 and 49% (n = 49) had International Staging System, stage III disease.Fluorescent in-situ hybridization (FISH) MM profiling was completed in 58% (n = 78).
Positivity for del 11q22 Coaster Holder was found in 23.7% (n = 14) with significantly more HIV-negative patients having the mutation (p = 0.027).
Overall, 42.2% (n = 57) achieved 2-year overall survival (OS).There were no significant differences in treatment (p = 0.
926) and 2-year survival outcome (p = 0.792) between the two groups.ConclusionThe incidence of HIV in newly diagnosed MM patients in KZN was increasing.
KZN patient profile differed from other reports by showing female predominance but was similar in advanced-stage presentation and bone fracture predominance.Statistically significant differences between the HIV-negative patients and PLWH were observed in age distribution and mutational landscape.Further studies are required in this area.
