Review
OBJECTIVE
To investigate the short-term efficacy and safety of different chemotherapy regimens combined with thalidomide, in the treatment of low-income patients with newly diagnosed HIV-associated diffuse large B-cell lymphoma.
METHODS
A retrospective analysis was performed on 42 patients with HIV-DLBCL who were admitted to the Infectious Diseases Department of Yunnan Provincial Infectious Diseases Hospital from January 2018 to December 2020. 14 cases (including 1 case in stage II and 13 cases in stage III/IV) were treated with R-CHOP, 24 cases (including 1 case in stage II and 23 cases in stage III/IV) were treated with R-DAEPOCH, and 4 cases (including 1 case in stage II and 3 cases in stage III/IV) were treated with EPOCH. All patients were treated with thalidomide. The ART regimen was adjusted. At least 1 and up to 6 intrathecal injections were given during chemotherapy, and cotrimoxazole was taken orally to prevent infection. The clinical efficacy was evaluated after 4 cycles of chemotherapy, and adverse events were evaluated at each cycle of chemotherapy.
RESULTS
All patients received 1-8 cycles of chemotherapy. CR (64.2 %) was achieved in 9 patients in R-CHOP group, and 5 patients died. In the R-DAEPOCH group, 17 patients achieved CR (70.8 %) and 7 died. In the EPOCH group, 2 patients reached CR (50 %) and 2 died. The main adverse reactions were grade II and above myelosuppression.
CONCLUSION
Combined treatment with thalidomide can improve the prognosis of low-income patients with newly diagnosed HIV-DLBCL.

INTRODUCTION
High-dose methotrexate (HDMTX) therapy poses challenges in various neoplasms due to individualized pharmacokinetics and associated adverse effects. Our purpose is to identify early risk factors associated with HDMTX-induced toxicities, paving the way for personalized treatment.
AREAS COVERED
A systematic review of PubMed and Cochrane databases was conducted for articles from inception to July 2023. Eligible studies included reviews, clinical trials, and real-world analyses. Irrelevant studies were excluded, and manual searches and citation reviews were performed. Factors such as MTX exposure, drug interactions, demographics, serum albumin, urine pH, serum calcium, and genetic polymorphisms affecting MTX transport (e.g. SLCO1B1), intracellular folate metabolism (MTHFR), cell development (ARID5B), metabolic pathways (UGT1A1, PNPLA3), as well as epigenetics were identified.
EXPERT OPINION
This comprehensive review aids researchers and clinicians in early identification of HDMTX toxicity risk factors. By understanding the multifaceted risk factors associated with hematologic malignancies, personalized treatment approaches can be tailored to optimize therapeutic outcomes.

BACKGROUND
Patients with relapsed intracranial germinoma can achieve durable remission with standard chemotherapy regimens and/or reirradiation; however, innovative therapies are required for patients with relapsed and/or refractory intracranial nongerminomatous germ cell tumors (NGGCTs) due to their poor prognosis. Improved outcomes have been reported using reinduction chemotherapy to achieve minimal residual disease, followed by marrow-ablative chemotherapy (HDCx) with autologous hematopoietic progenitor cell rescue (AuHPCR). We conducted a phase II trial evaluating the response and toxicity of a 3-drug combination developed for recurrent intracranial germ cell tumors consisting of gemcitabine, paclitaxel, and oxaliplatin (GemPOx).
METHODS
A total of 9 patients with confirmed relapsed or refractory intracranial GCT were enrolled after signing informed consent, and received at least 2 cycles of GemPOx, of which all but 1 had relapsed or refractory NGGCTs. One patient with progressive disease was found to have pathologically confirmed malignant transformation to pure embryonal rhabdomyosarcoma (without GCT elements), hence was ineligible and not included in the analysis. Patients who experienced sufficient responses proceeded to receive HDCx with AuHPCR. Treatment response was determined based on radiographic tumor assessments and tumor markers.
RESULTS
A total of 7 patients achieved sufficient response and proceeded with HDCx and AuHPCR, and 5 subsequently received additional radiotherapy. A total of 2 patients developed progressive disease while receiving GemPOx. Myelosuppression and transaminitis were the most common treatment-related adverse events. With a mean follow-up of 44 months, 4 patients (3 NGGCTs, 1 germinoma) are alive without evidence of disease.
CONCLUSIONS
GemPOx demonstrates efficacy in facilitating stem cell mobilization, thus facilitating the feasibility of both HDCx and radiotherapy.

Randomized Controlled Trial
BACKGROUND AND OBJECTIVES
To evaluate the potential benefits of Bacteroides fragilis 839 (BF839), a next-generation probiotics, in reducing myelosuppression and gastrointestinal toxicity associated with chemotherapy in breast cancer patient.
METHODS AND STUDY DESIGN
40 women with early breast cancer were randomly assigned to the BF839 (n=20) or placebo (n=20) during the administration of adjuvant chemotherapy (4 cycles of epirubicin 100mg/m2 and cyclophosphamide 600mg/m2). Myelosuppression and gastrointestinal adverse effects were monitored in both groups.
RESULTS
Throughout the four treatment cycles, the percentage of patients experiencing myelosuppression was 42.5% in the BF839 group, significantly lower than the 66.3% observed in the control group (p=0.003). Two patients in the BF839 group and three patients in the placebo group received recombinant human granulocyte colony-stimulating factor (rhG-CSF) due to leuko-penia/neutropenia. When considering an ITT analysis, which included all patients regardless of rhG-CSF treatment, the BF839 group exhibited less reduction from baseline in white blood cells (-0.31±1.19 vs -1.15±0.77, p=0.012) and neutrophils (0.06±1.00 vs -0.84±0.85, p=0.004) compared to the placebo group. The difference became even more significant when excluding the patients who received rhG-CSF injections. Throughout the four treatment cycles, compared to the placebo group, the BF839 group had significantly lower rates of 3-4 grade nausea (35.0% vs 71.3%, p=0.001), vomiting (20.0% vs 45.0%, p=0.001), and diarrhea (15.0% vs 30.0%, p=0.023).
CONCLUSIONS
These findings suggest that BF839 has the potential to effectively mitigate myelosuppression and gastrointestinal toxicity associated with chemotherapy in breast cancer patients.

Meta-Analysis
ETHNOPHARMACOLOGICAL RELEVANCE
Cordyceps sinensis (CS) is a fungus parasitic on lepidopteran larvae which is often used to treat lung diseases and regulate immune function.
AIM OF THE STUDY
This review aimed to evaluate the efficacy of CS in the adjuvant treatment of lung cancer.
MATERIALS AND METHODS
As of June 2022, the electronic database search was conducted in PubMed, EMBASE, Cochrane Library, China Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang Database and China Science Journal Database (VIP database). Randomized clinical trials (RCTs) that evaluated the efficacy of CS as an adjuvant treatment for lung cancer were included. After the quality evaluation, meta-analysis was performed with Stata 16.0 software.
RESULTS
A total of 12 RCTs with 928 patients were identified for this meta-analysis, which showed that as an adjuvant treatment, CS has the following advantages in the treatment of lung cancer: (1) Improved tumor response rate (TRR) (RR: 1.17, 95%CI: 1.05-1.29,P = 0.00); (2) improved immune function, including increased CD4 (MD: 4.98, 95%CI: 1.49-8.47, P = 0.01), CD8 (MD: 1.60, 95%CI: 0.40-2.81, P = 0.01, I = 0.00%), NK (MD: 4.17, 95%CI: 2.26-6.08, P = 0.00), IgA (MD: 1.29, 95%CI: 0.35-2.24, P = 0.01), IgG (MD: 3.95, 95%CI: 0.98-6.92, P = 0.01) and IgM (MD: 6.44, 95%CI: 0.63-12.26, P = 0.03); (3) improved patients' quality of life based on the mean ± SD of Karnofsky Performance Status (KPS) (MD: 8.20, 95%CI: 6.87-9.53, P = 0.00); (4) reduced the incidence of adverse drug reactions (ADRs), including the incidence of myelosuppression (RR: 0.38, 95%CI: 0.19-0.75, P = 0.01), leukopenia (RR: 0.76, 95%CI: 0.63-0.92, P = 0.00), and thrombocytopenia (RR: 0.52, 95%CI: 0.31-0.86, P = 0.01) (5) reduced the incidence of radiation pneumonitis (RR: 0.74, 95%CI: 0.62-0.88, P = 0.00). However, the number of improved patients based on KPS (RR: 1.47, 95%CI: 0.98-2.20, P = 0.06) were similar between two groups, liver and renal damage (RR: 0.32, 95%CI: 0.09-1.10, P = 0.07) and gastrointestinal adverse reactions (RR: 0.80, 95%CI: 0.47-1.37, P = 0.42) as well. Subgroup analysis showed that CS could increase the TRR in the treatment with 6 g/d and 21 days/3-4 cycles.
CONCLUSION
Compared with conventional treatment, adjuvant treatment with CS of lung cancer not only improve TRR, QOL and immune function, but also reduce the incidence of ADRs and radiation pneumonitis. The optimal usage may be 6 g/d and 21 days/3 to 4 cycles.

INTRODUCTION
Linezolid (LZD) plays an important role in the treatment of severe infections caused by Gram-positive bacteria. Thrombocytopenia is regarded as one of the most common side effects of linezolid, which results from the destruction of platelets or myelosuppression. The study aimed to identify the risk factors associated with the development of thrombocytopenia in Vietnamese patients.
METHODOLOGY
This retrospective, descriptive cross-sectional study was performed on adult patients who received parenteral LZD therapy (1,200 mg/day) in at least 3 days between January 2020 and June 2021 at a tertiary referral hospital in Vietnam. Thrombocytopenia was defined as either a final platelet count of less than 100 G/L or a 25% decrease in platelet count from baseline. Multivariate logistic regression analysis was applied to predict risk factors associated with LZD-induced thrombocytopenia.
RESULTS
In the 208 patients included in the study, the average age was 69 and males accounted for 73.1%. LZD-induced thrombocytopenia occurred in 37% of patients. LZD-induced thrombocytopenia was significantly associated with shock (HR = 8.26, 95% CI 3.82 - 17.84, p < 0.001), baseline creatinine clearance (HR = 1.02, 95% CI [1.01 - 1.03], p = 0.002), and duration of LZD treatment of at least 14 days (HR = 4.45, 95% CI [1.83 - 11.05], p = 0.001).
CONCLUSIONS
The results showed that thrombocytopenia was fairly common in patients using linezolid. Shock, renal failure, and duration of linezolid therapy of at least 14 days were significant risk factors for the incidence of linezolid-induced thrombocytopenia.

INTRODUCTION
Patients with severe neutropenia who develop septic shock (SS) have high mortality. This study aimed to evaluate the risk factors and mortality of SS in patients with HM and febrile neutropenia.
METHODOLOGY
We included all patients with hematological malignancies (HM) who presented fever and severe neutropenia, admitted to an oncological tertiary care center in Mexico City for one year.
RESULTS
Two hundred ninety-two episodes of fever and severe neutropenia were documented; 68 patients (23.2%) developed SS. Documented clinical infection was different between SS and non-SS patients (94.1% vs. 63.4%, p < 0.001); pneumonia was the most frequent infection (36.8% vs. 23.2%, p = 0.02). Also, in SS vs. non-SS, there were more positive cultures (69.1% vs. 38.4%, p < 0.001), higher frequency of Gram-negative bacteria (89.3% vs. 63.9%, p < 0.001), particularly Escherichia coli (68% vs. 44.2%) and Klebsiella spp. (23.4% vs. 15.1%). There were no differences when multidrug-resistant (MDR) microorganisms were compared. In the multivariate analysis, associated risk factors for SS were: prolonged neutropenia, a documented site of infection, and having received highly myelosuppressive chemotherapy. Risk factors for mortality at 30 days were: older patients, prolonged neutropenia, and SS.
CONCLUSIONS
Severe and prolonged neutropenia was associated with SS development and mortality at 30 days. ICU management should be offered to all critically ill patients with HM if long-term survival of the underlying malignancy is expected.

Review
Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic inflammation of the joints and bone destruction. Because of systemic administration and poor targeting, traditional anti-rheumatic drugs have unsatisfactory treatment efficacy and strong side effects, including myelosuppression, liver or kidney function damage, and malignant tumors. Consequently, mesenchymal stem cells (MSCs)-involved therapy is proposed for RA therapy as a benefit of their immunosuppressive and tissue-repairing effects. This review summarizes the progress of MSCs-involved RA therapy through suppressing inflammation and promoting tissue regeneration and predicts their potential clinical application.

A patient with disseminated nocardiosis developed pancytopenia after treatment with recombinant interferon-gamma (IFN-γ). While no previous clinical reports link pancytopenia to IFN-γ, our observations align with basic research on myelosuppressive effects of IFN-γ. Adjunctive IFN-γ may improve standard nocardiosis therapy, but vigilant monitoring of its hematologic effects is necessary.

Comparative Study
A real-world pharmacovigilance study of FDA Adverse Event Reporting System (FAERS) events for Bruton's tyrosine kinase inhibitors (BTKis) single and its combination therapy.
BACKGROUND
Bruton's tyrosine kinase inhibitors (BTKis) are targeted treatments for B-cell tumors but have significant side effects. This study assesses and contrasts the side effects of BTKis alone and its four combination therapies.
RESEARCH DESIGN AND METHODS
The reporting odds ratio (ROR) was used to analyze the data on three BTKis monotherapies and combinations of ibrutinib with rituximab, obinutuzumab, venetoclax, and lenalidomide in the FDA Adverse Event Reporting System (FAERS) database up to December 2022.
RESULTS
We analyzed the top 20 PTs for each treatment regimen. In monotherapies, atrial fibrillation (ROR (95% CI): 9.88 (9.47-10.32)) in zanubrutinib and rash (6.97 (5.42-8.98)) in acalabrutinib had higher associations. In combinations, infection (6.86 (6.11-7.70)), atrial fibrillation (27.96 (22.61-34.58)) and myelosuppression (10.09 (8.89-11.46)) were vital signals when ibrutinib was combined with obinutuzumab, and pyrexia (4.22 (2.57-6.93)) had a high signal value when combined with lenalidomide. Hemorrhage had a lower signal value when combined with venetoclax compared to ibrutinib alone (2.50 (2.18-2.87) vs 3.60 (3.52-3.68)).
CONCLUSIONS
The ibrutinib-obinutuzumab combo has the highest risk of infection, atrial fibrillation, and myelosuppression, and the ibrutinib-lenalidomide combo has the highest risk of pyrexia. However, the ibrutinib-venetoclax combo has a lower risk of hemorrhage than monotherapy.
