The Relationship between Hematopoietic Scoring System Composed of HB，PLT and MCV and Prognosis and Curative Effect of Multiple Myeloma Patients / 中国实验血液学杂志

OBJECTIVE@#To investigate the prognostic value of hemopoietic scoring system composed of hemoglobin (HB), platelet count (PLT) and mean corpuscular volume (MCV) in MM patients and its correlation with curative effect.@*METHODS@#The clinical data of 172 newly diagnosed MM patients treated by bortezomib as the first-line regimen in our hospital from May 2014 to December 2019 were collected, three variables (HB≤100 g/L, PLT≤150×109/L, MCV≥96 fl) were introduced, each variable was distributed 1 score, the patients were divided into four groups (0, 1, 2 and 3 points in group 1, 2, 3 and 4, respectively), and the clinical characteristics and prognosis of the patients in the four groups were analyzed. The initial efficacy evaluation after 3-4 courses of treatment was carried out, and the curative effect of the patients in the different hematopoiesis score groups were compared.@*RESULTS@#The median OS time of the patients in group 1, 2, 3 and 4 was 27.0, 22.5, 20.7 and 18.1 months, while the median PFS time were 23.0, 19.0, 18.0 and 14.0 months, respectively. The OS and PFS of the patients in low score group were significantly better than those in high score group (P=0.045, P=0.048). There was no significant difference in the curative effect of the patients treated by bortezomib after 3-4 courses (P>0.05).@*CONCLUSION@#Hematopoiesis score can preliminarily predict the overall survival of newly diagnosed MM patients, but there is no significant difference between different scoring groups in the initial curative effect.

Evaluation of the Efficacy and Safety of Chemotherapy in Elderly Patients with Multiple Myeloma under Different Frailty Scores / 中国实验血液学杂志

OBJECTIVE@#To compare the efficacy and safety of different chemotherapy regimens in elderly multiple myeloma (MM) patients with different Frailty scores.@*METHODS@#The clinical data of elderly patients with MM were retrospectively analyzed, including age, treatment regimen, efficacy, adverse reactions, and the Frailty score included in the activity of daily living score, the instrumental activity of daily living scale and the Charlson comorbidity index. The patients were divided into fit group, mediate fit group and frail group according to the scoring standard. The treatment efficiency and adverse reaction rates of elderly MM with different physical conditions treated by different chemotherapy regimens were analyzed.@*RESULTS@#Among the 70 patients, the effective rates of the patients in fit group, the mediate fit group, and the frail group were 79.5%, 81%, and 40%, and the effective rates of the fit patients in double and triple groups were 54.5% and 89.3%, 70% and 90.9% for mediate fit patients, 42.9% and 33.3% for frail patients, the triple regimen in fit patients showed obvious advantages, and the difference showed statistically significant (P<0.05), while the efficacy for mediate patients and frail patients showed no significant difference. During the induction of bortezomib, the incidence of adverse reactions for the patients in the triple group (78.6%) was higher than 67.9% in the double group, and the difference showed no statistically significant (P>0.05).There was no significant difference in the 1-year overall survival rate of the patients and with molecular genetic abnormalities among each groups.@*CONCLUSION@#The therapeutic effect is related to the patient's physical condition. For patients with healthy physique, the triple regimen should be used first. For patients with weak physical constitution, the chemotherapy regimen with low drug toxicity should be selected for safety.

Clinical Characteristics and Prognosis of Multiple Myeloma Patients with Myelofibrosis / 中国实验血液学杂志

OBJECTIVE@#To investigate the clinical characteristics and prognosis of multiple myeloma patients with myelofibrosis.@*METHODS@#The clinical data of 263 patients with multiple myeloma (including 92 patients with myelofibrosis) treated in the department of hematology of our hospital from January 1, 2016 to June 31, 2020 were collected and retrospectively analyzed, the patients were divided into combined group and uncombined group. The MM stage, MM type, genetic characteristics and therapeutic effect of the patients in combined group and uncombined group were observed, and the relationship between the curative effect and the degree of myelofibrosis change of the patients in combined group was analyzed.@*RESULTS@#There was no statistically difference in the MM staging and classification between multiple myeloma patients with or without myelofibrosis (P>0.05). The positive rate of FISH results of the patients in combined group was significantly higher than those in uncombined group, and was significantly correlated to 1q21 amplification, D13S319 deletion, and IgH breakage (P<0.05). After treatment, the effective rate of the patients in uncombined group was significantly higher than those in combined group, and the degree of fibrosis in the effective patients in combined group was significantly reduced.@*CONCLUSION@#The survival rate of the patients with multiple myeloma complicated with myelofibrosis is shorter than that of the patients without myelofibrosis, and the overall prognosis is poor.
