OBJECTIVE: To explore the relationship between serum complement levels at diagnosis and prognosis in patients with aggressive non-Hodgkin lymphoma(NHL). METHODS: The clinical data of 102 patients with aggressive non-Hodgkin lymphoma diagnosed in the First Hospital of Lanzhou University from February 2017 to March 2023 were selected to analyze the correlation between serum complement C3 and C4 levels and prognosis of patients with aggressive NHL at the time of initial diagnosis. The optimal cut-off point of C3 and C4 were obtained by calculating the Jorden index through the receiver operating characteristic（ROC） curve, and 102 patients were divided into low C3 group (C3< 1.07) and high C3 group (C3≥1.07), low C4 group (C4< 0.255) and high C4 group (C4≥0.255). The effects of serum C3 and C4 levels on the prognosis of these patients were analyzed. RESULTS: ROC curve analysis showed that the area under the curve (AUC) of C3 and C4 in predicting the prognosis of aggressive NHL patients was 0.634 (95%CI ：0.525-0.743；P =0.025) and 0.651 (95%CI ：0.541-0.761；P =0.012), respectively. The optimal cut-off points for C3 and C4 were 1.07 and 0.255, respectively. K-M survival analysis showed that groups with high C3 and C4 levels had shorter progression-free survival (PFS) (P =0.0079; P =0.0092) and overall survival (OS) (P =0.021; P =0.021). Multivariate Cox analysis showed that high level serum complement C3 (HR=2.37, 95%CI : 1.07-5.24, P =0.034) and age ≥60 years (HR=2.34, 95%CI : 1.11-4.95, P =0.025) were independent risk factors for PFS in patients with aggressive NHL. High level complement C3 (HR=2.37, 95%CI : 1.09-5.13, P =0.029) and age ≥60 years at diagnosis (HR=2.40, 95%CI : 1.13-5.13, P =0.024) were independent risk factors for OS in patients with aggressive NHL. CONCLUSION The level of serum complement C3 at diagnosis is one of the prognostic factors in patients with aggressive NHL.

OBJECTIVE: To investigate the effects of histone deacetylase (HDAC) levels on the proliferation and apoptosis of Burkitt lymphoma cells, and the changes in related signaling molecules in the PI3K/AKT/mTOR signaling pathway, so as to explore the pathogenesis of Burkitt lymphoma. METHODS: HDAC levels in Burkitt lymphoma were detected by RT-PCR and Western blot. CA46 and RAJI cells were treated with the HDAC selective inhibitor VPA. CCK8 assay was used to detect the proliferation ability of cells. Western Blot was used to measure the expression of apoptosis-related proteins, PI3K/AKT/mTOR signaling pathway proteins and their phosphorylation levels. RESULTS: The expression levels of classⅠ HDAC in Burkitt lymphoma were higher than those in normal cells, and the HDAC1 inhibitor VPA could inhibit the proliferation of CA46 and RAJI cells. VPA decreased HDAC expression in CA46 and RAJI cells, inhibited the phosphorylation of PI3K/AKT/mTOR pathway molecules AKT and p70S6K, increased the expression of apoptotic proteins Cleaved Caspase-3, Cleaved Caspase-8, Cleaved Caspase-9 and Bax, and decreased the expression of anti-apoptotic proteins Bcl-2 and PARP. CONCLUSION Inhibition of HDAC activity can Attenuate the proliferation of Burkitt lymphoma cells and induce apoptosis by inhibiting the PI3K/AKT/mTOR signaling pathway activity.

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 investigate the predictive value of endothelial activation and stress index (EASIX) for the prognosis of patients with mantle cell lymphoma (MCL). METHODS: A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023, had therapeutic indications and received standard treatment. RESULTS: A total of 66 patients were included and divided into high EASIX group and low EASIX group, according to a cutoff value of 0.97 determined by the receiver operating characteristic (ROC) curve. Multivariate Cox regression analysis showed that prealbumin <0.2 g/L, high EASIX, and ECOG PS score ≥2 were independent risk factors influencing overall survival (OS) in MCL patients. The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months, and the median progression-free survival was 8.8 and 26.0 months, respectively. The proportions of patients with ECOG PS score ≥2 and prealbumin <0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group. CONCLUSION At the time of initial diagnosis, EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL. Furthermore, patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

(+)-Strebloside, a significant bioactive compound isolated from the roots of Streblus asper Lour., demonstrates inhibitory effects against multiple malignancies. However, its specific function and underlying mechanistic pathways in Non-Hodgkin lymphoma (NHL) remain unexplored. This investigation sought to elucidate the role and potential mechanisms of (+)-strebloside-induced NHL cell death. The results demonstrated that (+)-strebloside significantly induced apoptosis and ferroptosis in NHL cells, including those from Raji cell-derived xenograft models. Mechanistic analyses revealed that (+)-strebloside enhanced six-transmembrane epithelial antigen of prostate 3 (STEAP3)-induced ferroptosis in NHL, and STEAP3 inhibition reduced the proliferation-inhibitory effects of (+)-strebloside. Furthermore, (+)-strebloside suppressed NHL proliferation through the mitogen-activated protein kinase (MAPK) pathway, and extracellular signal-regulated kinase (ERK) inhibition diminished the proliferation-inhibitory activity induced by (+)-strebloside. These findings indicate that (+)-strebloside presents promising therapeutic potential for NHL treatment.

Lymphomatoid Papulosis (LyP) is a rare skin disorder characterized by chronic, recurrent papules and nodules that heal spontaneously. This report discusses an 8-year-old Filipino female with a three-month history of erythematous pruritic papules evolving into plaques. A skin biopsy confirmed CD30-negative LyP, and treatment with Methotrexate resulted in significant improvement of the lesions. This case illustrates the complex diagnostic and therapeutic journey of LyP in children, emphasizing the importance of careful clinicopathologic correlation and the challenges of management due to the lack of curative therapy and the risk of malignant transformation.

18F-Fluorodeoxyglucose (18F-FDG) PET/CT scan is a vital imaging modality in the majority of oncologic situations. It is proven useful in staging, management and monitoring of lymphomas. Numerous subtypes of lymphomas exist; however, we present the first documented case of a 56-year-old, Filipino, male patient who is diagnosed with mantle cell lymphoma of the conjunctiva (MCL). MCL is an extremely rare type of extranodal non-Hodgkin lymphoma and has an aggressive nature with an estimated incidence of 2-4/1,000,000. This case highlights the critical role that PET/CT scans play in directing treatment decisions and monitoring the response of conjunctival MCL to therapy.
