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.

Extramedullary hematopoiesis (EMH) is occasionally reported in idiopathic myelofibrosis and is generally found in the liver, spleen, and lymph nodes several years after diagnosis. Myelofibrosis presenting as spinal cord compression, resulting from EMH tissue is very rare. A 39-yr-old man presented with back pain, subjective weakness and numbness in both legs. Sagittal magnetic resonance imaging showed multiple anterior epidural mass extending from L4 to S1 with compression of cauda equina and nerve root. The patient underwent gross total removal of the mass via L4, 5, and S1 laminectomy. Histological analysis showed islands of myelopoietic cells surrounded by fatty tissue, consistent with EMH, and bone marrow biopsy performed after surgery revealed hypercellular marrow and megakaryocytic hyperplasia and focal fibrosis. The final diagnosis was chronic idiopathic myelofibrosis leading to EMH in the lumbar spinal canal. Since there were no abnormal hematological findings except mild myelofibrosis, additional treatment such as radiothepary was not administered postoperatively for fear of radiotoxicity. On 6 month follow- up examination, the patient remained clinically stable without recurrence. This is the first case of chronic idiopathic myelofibrosis due to EMH tissue in the lumbar spinal canal in Korea.

Primary myelofibrosis (PMF) is easily confused with cirrhosis, due to its main clinical manifestations of splenomegaly and the blood cytopenia. This review focuses on clinical studies to identify primary myelofibrosis and cirrhosis related portal hypertension, to analyze the differences between the two diseases, in order to distinguish PMF and cirrhosis from the pathogenesis, clinical manifestations, laboratory examinations and treatment principles, and simultaneously improve clinicians' understanding of PMF, which is a reference for exploring the early screening or diagnostic indicators of PMF, also provides a clinical basis for the application of new targeted drugs such as ruxolitinib.

OBJECTIVETo investigate the value of myeloproliferative neoplasms Symptom Assessment Form total symptom score (MPN-SAF-TSS)in assessing constitutional symptoms among Ph/BCR- ABL negative myeloproliferative neoplasm (MPN)patients.
METHODSA cohort of 628 MPN patients were evaluated by MPN- SAF- TSS.
RESULTSFatigue was the most common symptom (76.0%, 76.2%vs 89.9%)and the highest average severity of all the symptoms (3.46±2.97, 3.47±2.99vs 4.74±3.04 scores)among polycythemia vera (PV), essential thrombocythemia (ET)and primary myelofibrosis (PMF)patients. Using the MPN- SAF- TSS analysis, PMF patients showed highest burden of symptoms (28.9 ± 19.1), followed by PV patients (19.2 ± 16.8), and finally ET patients (17.1 ± 15.3). Instinct differences were observed between PMF and PV patients (χ(2)=6.371,P=0.021), PMF and ET patients (χ(2)= 14.020,P<0.001). No significant difference was found between PV and ET patients (χ(2)=2.281,P=0.191).
CONCLUSIONMPN- SAF- TSS was effective in evaluating the symptomatic burden among Ph/BCRABL negative MPN patients and could be used for serial assessment in this clinical setting.

Essential thrombocythemia (ET) is a chronic myeloproliferative neoplasm that involves primarily the megakaryocytic lineage. After many years, a few patients with ET may develop bone marrow (BM) fibrosis and rarely develop osteosclerosis. A 60-yr-old female was admitted due to severe left upper quadrant abdominal discomfort. She had been diagnosed as ET 19 yrs ago. On liver computed tomography severe splenomegaly was shown. Laboratory tests revealed WBC 24.3x10(9)/L, hemoglobin 13.4 g/dL, platelets 432x10(9)/L, lactate dehydrogenase 4,065 IU/L (reference range; 240-480). Blood smear demonstrated leukoerythroblastosis, teardrop cells, and giant and hypogranular platelets. BM study revealed inadequate aspirate due to dry tap. BM biopsy showed clusters of dysplastic megakaryocytes, grade 3 fibrosis, and severe osteosclerosis. Major/minor BCR-ABL1 rearrangement and JAK2 V617F mutation were not detected. Cytogenetic studies revealed normal karyotype. According to the 2008 WHO diagnostic criteria, the patient was diagnosed as having post-essential thrombocythemia myelofibrosis with severe osteosclerosis.

7.Case of Bilateral Retinal Neovascularization Associated with Chronic Idiopathic Myelofibrosis.
Korean Journal of Ophthalmology 2010;24(2):131-133
We report a case of bilateral peripheral retinal neovascularization and chronic idiopathic myelofibrosis in a 69-year-old man. Ophthalmic examination revealed peripheral retinal nonperfusion with retinal neovascularization in both eyes and vitreous hemorrhage in the right eye. Fluorescein angiography of both eyes showed a marked midperipheral and peripheral avascular retina temporally with arteriovenous anastomosis and sea-fan neovascularizations. Blood tests showed pancytopenia and teardrop-shaped red blood cells, and bone marrow examination showed hypocellular marrow with severe fibrosis. The neovascularization was regressed following pars plana vitrectomy in the right eye and scatter laser photocoagulation in the left. The results suggest that peripheral retinal vessel occlusion and neovascularization may be associated with idiopathic myelofibrosis.

OBJECTIVETo analyze the clinical features and prognosis of the primary myelodysplastic syndrome with myelofibrosis (MDS-MF) patients and to improve the cognition of MDS-MF.
METHODSFour hundred and sixty-six primary MDS patients with bone marrow (BM) biopsy were divided into two groups according to whether BM associated with fibrosis, the clinical features and prognosis of the two groups were analyzed retrospectively.
RESULTS167 (35.8%) MDS cases revealed myelofibrosis, of which MF-1 123 cases (26.4%), MF-2 40 cases (8.6%), MF-3 4 cases (0.9%). The proportion of hepatosplenomegaly in MDS-MF group was significantly higher than in MDS without MF group, the difference had statistical significance (P = 0.031). The proliferation of BM biopsy in MDS-MF group was significantly more active than in MDS without MF group. The number of blasts, megakaryocytes and abnormal megakaryocytes in MDS-MF group were significantly higher than in MDS without MF group, the differences had statistical significance (P < 0.05). Among the 345 patients who had available results of cytogenetic analysis, 121 cases were MDS-MF patients, the proportion of middle and high-risk prognostic group according to IPSS karyotype prognosis groups in MDS-MF group were significantly higher than in MDS without MF group, the differences had statistical significance (P = 0.047). The median survival was 17 (1 - 60) months in MDS-MF group, and was 32 (1 - 62) months in MDS without MF group. The difference had statistical significance (P = 0.001). Myelofibrosis had independent prognostic significance by multi-variable analysis (P = 0.019).
CONCLUSIONThe myelofibrosis in MDS is main the proliferation of reticular fiber. The proliferation of reticular fiber is closely related with the number of blast cells, the proliferation and developmental abnormalities of megakaryocytes and the karyotype. The prognosis of MDS-MF patients is poor.

To improve the recognition of immunoglobulin D multiple myeloma and explore its clinical feature and laboratory examination characteristics, so as to reduce the the missed diagnosis and misdiagnosis, a case of IgD multiple myeloma (MM) with myelofibrosis and bone marrow necrosis is reported. The clinical feature, treatment and prognosis of IgDlambda MM were discussed. Immunoglobulin D multiple myeloma is a rare disease and predominantly occurs in young male patients, which shows an aggressive clinical course with poor response to conventional treatment and unfavorable prognosis. Immunoglobulin D multiple myeloma was usually misdiagnosed as a light chain type multiple myeloma by using routine laboratory examination. Immunoglobulin D monoclonal protein is not easy to be detected owing to its low protein level, resulting in missed diagnosis. Immunofixation electrophoresis is highly sensitive and specific for diagnosis of IgD MM, can enhance accuracy of diagnosis for this rare disease.

OBJECTIVETo reassess the natural history of polycythemia vera (PV) in Chinese and evaluate the relationship between the incidence of thrombosis, post-polycythaemic myelofibrosis with myeloid metaplasia( PPMM) , leukemia transformation and the therapeutic outcome and prognostic factors.
METHODSThe clinical manifestations, laboratory parameters and treatment were retrospectively analyzed in 287 patients with PV. Univariate analysis of prognostic factors was performed using Log-rank model and multivariate analysis using COX model in term of the incidence of thrombosis, PPMM, hematologic or non hematologic cancers and mortality.
RESULTSOf the 287 patients, the median follow-up time was 46 (8-360) months. 208 thromboses were recorded in 115 patients. Twice or more thrombotic events occurred on 59 patients (51.34%). Most of these episodes occurred either at presentation or in the 2 years before diagnosis. Elder patients, prior thrombosis, poor response to therapy were associated with poor prognosis. With these three adverse prognostic factors, the patients could be separated into different risk groups. The incidence of thrombosis was higher in high risk group. 36 patients progressed to PPMM, the median time to PPMM was 80 (7-190) months. Higher WBC count, splenomegaly and treatment with alkylating agent and hydroxy-carbamide (HU) were associated with poor prognosis. 2 cases progressed to AML. 1 to lymphoma and 1 to nonhematologic cancer. 13 patients died, the cause of death was fatal thrombosis in 9 and AML in 2.
CONCLUSIONThe incidence of thromboembolism is higher and the time to myelofibrosis was shorter in Chinese PV patients than in western PV patients. The main factors that influence the survival of PV patients are thromboembolism and leukemia transformation.
