OBJECTIVE: To retrospectively analyze the clinical characteristics and prognostic factors of patients with primary cutaneous lymphoma. METHODS: The clinical data of 22 patients with primary cutaneous lymphoma admitted to Xinjiang Hotan District People's Hospital, Heji Hospital affiliated to Changzhi Medical College and the Fifth Medical Center of PLA General Hospital from January 2013 to June 2021 were retrospectively analyzed. RESULTS: The incidence of primary cutaneous T cell and NK/T cell lymphoma was about 91.9/100 000, and the incidence of primary cutaneous B cell lymphoma was about 14.5/100 000. The overall survival (OS) of patients aged ≥65 years was significantly shorter than that of patients younger than 65 years (P <0.05). Patients with elevated β₂-microglobulin (β₂-MG) had shorter OS and progression-free survival (PFS) (both P <0.05). Patients who achieved complete/partial response after initial treatment had longer OS than those with stable or progressive disease (P <0.05). There were significant differences in OS and PFS among patients with different pathological types of primary cutaneous lymphoma that originated from T and NK/T cells, the OS and PFS of patients with mycosis fungoides were longer than those of patients with other pathological types (both P <0.05). In addition, disease stage might also affect the PFS of the patients (P =0.056). CONCLUSION The age, disease stage, β₂-MG level, pathological type and remission state after treatment of the patients were related to the clinical prognosis.

Early stage mycosis fungoides (MF) has been treated with skin directed therapies including topical steroids, phototherapy (UVB), photochemotherapy (PUVA), topical nitrogen mustard, or total skin electron beam therapy. Recently, several studies have been reported that treat early-stage MF with narrow band UVB (NBUVB), which is an effective and convenient modality compared to other alternatives. Herein, we describe two cases of early stage MF treated with NBUVB. During the remission induction therapy, oral acitretin combined with NBUVB was used for several weeks to clear the MF, followed by treatment with only NBUVB for maintenance.

All-trans retinoic acid (RA) is recognized to be a drug of choice in remission induction of acute promyelocytic leukemia (APL), with some side effects including retinoic acid syndrome. But Sweet syndrome in association with RA is usually not serious nor well recognized. Early recognition of Sweet syndrome is important because additional therapy for this syndrome except steroid is not necessary. We report a case of Sweet syndrome developed in a patient of APL during remission induction therapy with RA.

Objective: To analyze the percentage of myeloperoxidase (MPO)-positive acute myeloid leukemia (AML) blast cells, and to explore the correlation of MPO expression with the clinical features, gene alterations, therapeutic response and prognosis of AML. Methods: The expressions of MPO in BM blasts cells of 233 newly diagnosed AML were retrospectived analyzed, they were divided into two groups using the percentage of MPO-positive blast [low (≤70%) and high (>70%)], clinical features, gene alterations, chemotherapy efficacy and prognosis were compared between the two groups. Results: ①Of the 233 patients, 121(51.9%) were in the low MPO group, and the rest 112(48.1%) in the high MPO group. Favorable-risk group according NCCN guidelines of AML was always MPO-high (χ(2)=32.773, P<0.001), while MPO-low was closely related to poor-risk (χ(2)=7.078, P=0.008); ②DNMT3A mutation (χ(2)=6.905, P=0.009), spliceosome genes mutation (SF3B1/SRSF2/U2AF1) (χ(2)=5.246, P=0.022), RUNX1 mutation (χ(2)=4.577, P=0.032), ASXL1 mutation (χ(2)=7.951, P=0.005) and TP53 mutation (P=0.004) were more likely to be seen in the low MPO group, while C-KIT mutation (χ(2)=8.936, P=0.003) and CEBPA mutation (χ(2)=12.340, P<0.001) were more frequent in the high MPO group, especially CEBPA double mutation; ③The rates of first complete remission in the low MPO group were significantly lower than that in the high MPO group (38.8% vs 68.1%, χ(2)=15.197, P<0.001). Multivariate analysis showed that low MPO positivity significantly affected the CR(1) unfavourably. ④The overall survival (OS) and the progression-free survival (PFS) were significantly worse in the low MPO group (18.0% vs 89.4% for OS, and 11.5% vs 56.7% for PFS, P<0.001). Multivariate analysis disclosed that the low number of MPO was significantly unfavourable prognostic factor. ⑤The low MPO group still showed a worse survival even when restricted to the patients with normal karyotype, the OS and the PFS were 31.1% and 18.8% respectively. Conclusions: AML with different MPO expression percentage had a unique gene mutation spectrum. Low expression of MPO was an independent risk factor for CR(1), OS and PFS in AML patients, which may be a simple and highly significant factor for AML patients when evaluating the therapeutic efficacy and prognosis.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with acute myeloid leukemia(AML) combined with paroxysmal nocturnal hemoglobinuria(PNH). METHODS: The clinical data of 13 AML combined with PNH patients treated in our hospital from January 2017 to May 2019 were collected and retrospective analyzed. The complete remission(CR) rate for induction chemotherapy was analyzed. The level of PNH RESULTS: Among the 13 patients, 11 (84.6%) cases were CR after first induction chemotherapy. The median overall survival(OS) time was 17 months(0-30 months), the median progression-free survival(PFS) time was 16 months(2-26 months). There were no significant difference in the number of PNH CONCLUSION The patients of AML combined with PNH have higher CR rate after the first induction chemotherapy. The level of WBC and LDH at first diagnosed are the factors that affecting the OS of the patients. The OS of patients with WBC lower than 10×10

BACKGROUND: The overall prognosis of acute leukemia has dramatically improved in the past 20 years, primarily due to the use of intensive multiagent chemotherapy in combination with CNS prophylaxis. However, increased aggressiveness of treatment protocols was entailed a great risk of various toxic effects. Endocrine function was also affected. The aim of this study is to compare the effect of chemotherapy on thyroid function in children with acute leukemia. METHOD: Parameters of thyroid function during chemotherapy were measured in 11 children with acute leukemia. Level of the serum 73,74 and TSH were determined before therapy, 7th day and 30th day of chemotherapy. Determination of serum 73, 74 and TSH were performed by conventional radioimmunoassay technique. Statistical analysis was done using SAS software. RESULT: 1) Level of level 73 was normal in 7 cases before therapy and decreased in 9 cases on 7th day of remission induction therapy. On 30th day, 73 level was increased to normal value. 2) Level of 74 was normal before therapy and decreased on 7th day of therapy. On 30th day of therapy 74 level showed various change. Three of them showed sustained low level of 74 on 7th and 30th day. 3) Level of TSH were normal before therapy and decreased on 7th day of therapy, followed achievement of normal level after completion of induction therapy. CONCLUSION: We conclude that during induction chemotherapy in childhood acute leukemia, thyroid function was impaired which was reversible.

OBJECTIVETo compare the efficacy and toxicity of 10 mg/m² or 8 mg/m² idarubicin (Ida) combined with cytarabine (IA"3+7"regimen) as induction chemotherapy for adult patients with newly diagnosed acute myeloid leukemia (AML).

METHODSFrom June 2004 to October 2013, 335 adult AML (non acute promyelocytic leukemia) patients receiving the IA regimen as induction chemotherapy were enrolled, including 198 cases with 10 mg/m² Ida and 137 cases with 8 mg/m² Ida for 3 days. We compared the hematologic response, hematologic side effects and prognosis between the two regimens.

RESULTSExcept for 4 early deaths, the complete remission (CR) rate after the first cycle of induction chemotherapy was 72.5%, 10.0% partial remission (PR) and 82.5% overall remission (OR) rate. The CR and OR rates were higher in the 10 mg/m² Ida group than the 8 mg/m² Ida group (CR: 78.9% vs 63.5%, P=0.003; OR: 88.2% vs 75.4%, P=0.007). Multivariate analysis showed that female, HGB≥100 g/L, FLT3-ITD mutation negative and 10 mg/m² Ida were favorable factors for CR. All patients presented cytopenias of grade Ⅳ. There was no differences on the recovery time of ANC≥0.5×10⁹/L and PLT≥20×10⁹/L after induction chemotherapy. Within a median follow-up of 14 (1-118) months, 98 (29.3%) patients relapsed, 92 (27.5%) died. The disease-free survival (DFS) and overall survival (OS) at 3 years were 53.2% and 58.9%, respectively. DFS and OS at 3-year were 34.2% and 37.4% in the chemotherapy cohort, 74.5% and 81.2% in the transplant cohort. 10 mg/m² Ida was an independent favorite factor for DFS (P=0.040) and OS (P=0.007).

CONCLUSIONAs compared to 8 mg/m², 10 mg/m² Ida significantly improved the CR, with the same extent of hematological side effects, and was an independent favorite factor for DFS and OS.
