OBJECTIVES: To investigate the clinical characteristics and prognosis of chronic disseminated candidiasis (CDC) in children with acute leukemia (AL) following chemotherapy. METHODS: A retrospective analysis was conducted on children diagnosed with CDC (including confirmed, clinically diagnosed, and suspected cases) after AL chemotherapy from January 2015 to December 2023 at Fujian Medical University Union Hospital, Zhangzhou Municipal Hospital, and Quanzhou First Hospital Affiliated to Fujian Medical University. Clinical characteristics and prognosis were analyzed. RESULTS: The incidence of CDC in children with AL following chemotherapy was 1.92% (32/1 668). Among the children with acute lymphoblastic leukemia, the incidence of CDC in the high-risk group was significantly higher than in the low-risk group (P=0.002). All patients presented with fever unresponsive to antibiotics during the neutropenic period, with 81% (26/32) involving the liver. C-reactive protein (CRP) levels were significantly elevated (≥50 mg/L) in 97% (31/32) of the patients. The efficacy of combined therapy with liposomal amphotericin B and caspofungin or posaconazole for CDC was 66% (19/29), higher than with caspofungin (9%, 2/22) or liposomal amphotericin B (18%, 2/11) monotherapy. The overall cure rate was 72% (23/32). The proportion of patients with CRP ≥50 mg/L and/or a positive β-D-glucan test for more than 2 weeks and breakthrough infections during caspofungin treatment was significantly higher in the treatment failure group compared to the successful treatment group (P<0.05). CONCLUSIONS CDC in children with AL after chemotherapy may be associated with prolonged neutropenia due to intensive chemotherapy. Combination antifungal regimens based on liposomal amphotericin B have a higher cure rate, while persistently high CRP levels and positive β-D-glucan tests may indicate poor prognosis.

OBJECTIVE: To investigate the efficacy and safety of zanubrutinib in the treatment of autoimmune cytopenia (AIC) secondary to indolent B-cell lymphoma (iBCL). METHODS: A total of 23 patients with iBCL complicated with AIC who were admitted to our hospital from December 2019 to September 2023 were selected as the research subjects. All patients were administered zanubrutinib 160 mg, twice daily, and continued oral administration. The objective response rate (ORR) of AIC, the therapeutic effect on lymphoma, and the incidence of adverse reactions were observed. RESULTS: After a median follow-up of 20 (5 to 48) months, the median duration of response was 9 (interquartile range [IQR] 5-24)months. AICA efficacy assessment showed that there were 10 cases of complete remission (CR), 9 cases of partial remission (PR), and 4 cases of no response (NR), and the ORR was 82.6% (19/23) (95%CI : 61.2-95.0). Among them, for the 14 patients with autoimmune hemolytic anemia (AIHA), 7 achieved CR, 5 had PR, and 2 had NR. For the 4 patients with immune thrombocytopenia (ITP), 1 reached CR, 2 had PR, and 1 had NR. Regarding the 5 patients with Evans syndrome (ES), 2 achieved CR, 2 had PR, and 1 had NR. The assessment of lymphoma efficacy showed that there were 10 cases of CR , 7 cases of PR , 6 cases of stable disease (SD), and no progressive cases, with an ORR of 73.9% (17/23) (95%CI : 51.6-89.8). The main adverse reactions during the treatment were infection, hemorrhage, neutropenia, elevated lymphocyte count, rash, and anemia. Most of these adverse reactions were grade 1-2 and tolerable. No arrhythmia and hypertension occurred, and no deaths due to adverse reactions. CONCLUSION Zanubrutinib is effective and safe for AIC secondary to iBCL.

OBJECTIVE: To analyze the clinical characteristics, treatment effect and prognosis of patients with non-Hodgkin lymphoma (NHL) complicated by hypercalcemia. METHODS: The clinical features, treatment and prognosis of 47 patients with NHL complicated by hypercalcemia in Ningde Municipal Hospital of Ningde Normal University and Affiliated Hospital of Nantong University from January 2018 to January 2023 were retrospectively analyzed. RESULTS: Among the 47 lymphoma patients, 33 cases were T-cell NHL, 14 cases were B-cell NHL. The median serum calcium level of the 47 patients was 3.10 (2.77-4.86) mmol/L, with 27 cases (57.4%) experiencing mild hypercalcemia (2.75-3.00 mmol/L), 8 cases (17.0%) experiencing moderate hypercalcemia (3.00-3.50 mmol/L), and 12 cases (25.5%) experiencing severe hypercalcemia (>3.50 mmol/L). All 47 patients were treated with hydration, alkalization, diuresis, etc. 32 cases (68.1%) received combination chemotherapy, 21 cases (44.7%) received salmon calcitonin treatment, and 3 cases were treated with denosumab in 5 patients with renal insufficiency. After treatment, 38 patients' serum calcium gradually returned to normal, with a median recovery time of 6 (1-18) days, while 9 patients still failed to recover their serum calcium after treatment and all died within 1 month. 32 patients undergoing combination chemotherapy were evaluated for efficacy after 2-4 courses of chemotherapy. Among them, 8 cases (25.0%) achieved complete response (CR), 11 cases (34.4%) achieved partial response (PR), 7 cases (21.9%) showed stable disease (SD), and 6 cases (18.8%) showed progressive disease (PD). The median follow-up time was 10 months. There were 13 cases of disease progression after combination chemotherapy and a total of 28 deaths. The survival time ranged from 0.8 to 23.7 months, and the median progression time was 4.9 months. Multivariate Cox regression analysis showed that the T-cell NHL, blood calcium >3.5 mmol/L, and no decrease in blood calcium after treatment were independent risk factors for the OS, and the T-cell NHL was independent risk factors for the PFS. CONCLUSION NHL complicated by hypercalcemia has a poor prognosis, and hypercalcemia can be used as one of the indicators reflecting the tumor burden. Patients with NHL complicated by hypercalcemia should be given more clinical attention and treated actively.

OBJECTIVE: To explore the risk and location of multiple malignancies in patients with hematologic malignancies who were followed up for 9 years in Jiangsu Province Hospital and to evaluate the impact of the second primary malignancy on survival of patients. METHODS: The incidence and survival of multiple malignancies in 7 921 patients with hematologic malignancies from 2009 to 2017 were analyzed retrospectively. RESULTS: A total of 180 (2.3%, 180/7 921) patients developed second malignancy, of whom 58 patients were diagnosed with hematologic malignancies as the first primary malignancy, and 98 patients developed hematologic malignancies as second primary malignancy, and the other 24 cases were diagnosed with the second malignancy within 6 months after the first primary malignancy was diagnosed, which was difined as multiple malignancies occurring simultaneously. In 180 patients, 18 cases developed two hematologic malignancies successively, and 11 patients developed more than 3 primary cancers (among them, 2 female patients were diagnosed with 4 primary cancers). Patients with lymphoma and multiple myeloma (MM) as the second primary malignancy had poorer survival than patients with lymphoma and MM as the first primary malignancy. Patients with chronic myeloid leukemia as the second primary malignancy were also associated with inferior overall survival. CONCLUSION In this study, 2.3% of hematologic malignancy patients had multiple mali-gnancies, lymphoma and MM as the second primary malignancy had poor survival.

Objective: To evaluate the clinical characteristics, treatment, and prognosis of patients with paraneoplastic neurological syndrome (PNS) associated with lymphoma. Methods: Between January 2012 and May 2021, the clinical data of 11 patients with lymphoma complicated with PNS treated at Peking Union Medical College Hospital were retrospectively reviewed. Results: Among the 11 patients (8 male and 3 female) , the median onset age was 61 (range, 33-78) years. The symptoms of PNS preceded lymphoma in 10 patients. The median time from the onset of PNS to the diagnosis of lymphoma was 4 months. Of the 11 patients, one had Hodgkin's lymphoma, 8 had B-cell non-Hodgkin's lymphoma, and 2 had peripheral T-cell lymphoma. Seven patients were evaluated for onconeural antibody, of whom 2 were positive (1 for anti-Ma2 antibody and 1 for anti-Yo antibody) . Of the 11 patients, the PNS symptoms of 3 patients were located in the central nervous system, 4 were located in the peripheral nervous system, and 3 were located in the muscle. Eight of the 11 patients were treated with glucocorticoid-based immunosuppressive therapy before the diagnosis of lymphoma. Patients with central nervous system involvement and dermatomyositis responded well to glucocorticoid, whereas patients with peripheral neuropathy did not significantly benefit. All 11 patients were treated with chemotherapy after the diagnosis of lymphoma. The efficacy of chemotherapy was assessed in 9 patients, 7 cases achieved complete remission, 1 case was evaluated as stable disease, and 1 case was evaluated as disease progression. The PNS symptoms of the patients who achieved complete response were almost completely recovered. The median follow-up time was 42 (range, 4-95) months. At the end of the follow-up period, 6 of the 11 patients survived, 3 were lost to follow-up, and 2 died. The median overall survival of the whole group was not reached. Conclusions: PNS can involve various parts of the nervous system and can be associated with different types of lymphoma. Through early diagnosis and treatment, the PNS symptoms could improve in most patients who achieve complete remission of lymphoma.

Objective: To investigate the clinicopathological features and prognosis of cytotoxic T-cell lymphoma (CTL). Methods: The clinicopathological data of 134 CTL patients in Beijing Friendship Hospital Affiliated to Capital Medical University, the 989 Hospital of PLA Joint Logistics Support force (formerly the 152 Hospital) and the Fourth Hospital of Hebei Medical University from 2008 to 2020 were retrospectively collected. Immunophenotype, Epstein-Barr virus infection status and T cell receptor (TCR) clonality of tumor cells were assessed, and clinicopathological features and prognosis of patients were analyzed. Results: Among the 134 CTL patients, the male to female ratio was 1.7∶1.0, the median age was 49.5 years (range 3-83 years), and 100 cases (74.6%) were under 60 years old. Forty-six point nine percent of the patients (53/113) had B symptoms. Most of the patients presented with systemic superficial lymphadenopathy. According to the Ann Arbor staging system, 36.8% (39/106) of the patients were in stage Ⅰ-Ⅱ, and 63.2% (67/106) in stage Ⅲ-Ⅳ. The rate of extranodal involvement was 51.6% (66/128). Spleen was involved in 24.2% (31/128) of the cases. Morphology showed diffuse growth of abnormal lymphocytes, infiltrating and destroying normal tissue structure. Immunohistochemical staining showed that tumor cells expressed T cell antigens (CD2, CD3, CD5, and CD7), and 72.0% (77/107) of them had decreased or lost expression of one or more antigens. According to the numbers of CD4 and CD8 expression in tumor cells, 70 cases (52.2%) were grouped into CD8⁺>CD4⁺group. The expression rates of TIA-1 and granzyme B were 99.2% (119/120) and 79.8% (95/119), respectively. CD20 abnormal expression rate was 27.6% (37/134) and CD56 was negative in all cases. The median Ki-67 proliferative index was 45.0% (range 5%-80%). In situ hybridization of small RNA encoded by Epstein-Barr virus was negative. Clonal TCR gene rearrangement analysis was performed on 49 cases and was positive in all cases. Ninety-one patients were followed up for a median of 36 months (range, 1 to 240 months), and 40 of the 91 patients (44.0%) died. The twenty-three patients were in complete remission (including 13 cases with localized single extranodal mass). The 3-year and 5-year overall survival rates were 53.5% and 49.4%, respectively. Univariate analysis showed that B symptom, spleen involvement, extranodal involvement, clinical stage, CD8⁺>CD4⁺phenotype, abnormal expression of CD20 and Ki-67 proliferation index (>60%) were associated with overall survival (P<0.05). The multivariate Cox regression analyses showed that spleen involvement and CD8⁺>CD4⁺ phenotype were independent prognostic factors for overall survival in CTL patients. Conclusions: CTL are more commonly found in adult males under 60 years old, often accompanied by B symptom, with a high proportion of extranodal involvement and more CD8 positive phenotypes. Spleen involvement and CD8⁺>CD4⁺phenotype are independent predictors of CTL overall survival. Some patients with localized extranodal CTL may have a good prognosis.

Objective: To investigate the clinicopathological characteristics and prognosis of mature T/NK cell lymphomas with aberrant CD20 or CD79α expression. Methods: A retrospective analysis of 641 cases of mature T/NK cell lymphoma diagnosed from January 2014 to December 2020 was performed, and 14 cases of CD20-positive and one case of CD79α-positive mature T/NK-cell lymphoma were identified. Histological examination, immunohistochemical characterization, in situ hybridization for Epstein-Barr virus encoded early RNA (EBER), and PCR testing for immunoglobulin and T cell receptor (TCR) gene rearrangements were performed. Clinicopathological characteristics of these lymphomas were analyzed. Results: There were 13 males and 2 females, with a median age of 56 years. There were 8 cases of peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), 3 cases of extranodal NK/T-cell lymphoma, nasal type (ENKTCL), 2 cases of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) and 2 cases of angioimmunoblastic T-cell lymphoma (AITL). Twelve cases were stage Ⅲ or Ⅳ lymphomas. The prognosis was overall poor. The histology, immunophenotype and TCR gene rearrangement were not significantly different from the corresponding types of lymphoma. Ki-67 proliferation index was over 70% in all cases. The expression of CD20 or CD79α was weak and heterogeneous. All 15 case of Ig gene rearrangement were polyclonal. Conclusions: Mature T/NK cell lymphoma with abnormal expression of CD20 or CD79α is rare, commonly found in advanced stage, and associated with poor prognosis. The expression of CD20 or CD79α in these cases is weaker than the corresponding mature T/NK cell lymphomas, while its proliferation index is higher. Histomorphology, extensive immunoprofiling and molecular detection are required for accurate diagnosis.
