Meta-Analysis
BACKGROUND
Concurrent chemoradiotherapy (CCRT) has become the cornerstone of treatment for patients with locally advanced non-small cell lung cancer (LA-NSCLC). The aim of this study was to compare the efficacies and toxicities of different CCRT regimens in the treatment of LA-NSCLC by adopting a network meta-analysis (NMA).
METHODS
An exhaustive search of PubMed, EMBASE, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL) was conducted to identify relevant studies from inception to October 1, 2020. Direct and indirect evidence was combined to calculate the odds radios (ORs) and 95% confidence intervals (CIs), as well as to plot the surface under the cumulative ranking (SUCRA) curves. Cluster analyses were adopted to compare the efficacies and toxicities of different CCRT regimens according to the similarity of 2 variables. Publication bias was detected by comparison-adjusted funnel plots.
RESULTS
Twenty-two studies were enrolled in this NMA, including 18 regimens: CCRT (cisplatin + etoposide), CCRT (carboplatin + paclitaxel), CCRT (pemetrexed + carboplatin), CCRT (pemetrexed + cisplatin), CCRT (docetaxel + cisplatin), CCRT (S-1 + cisplatin), CCRT (mitomycin + vindesine + cisplatin), CCRT (cisplatin + vinorelbine), CCRT (cisplatin), CCRT (etoposide + cisplatin + amifostine), RT, CCRT (5-FU), CCRT (paclitaxel + cisplatin), CCRT (irinotecan + carboplatin), CCRT (nedaplatin), CCRT (carboplatin + etoposide), CCRT (paclitaxel), and CCRT (carboplatin). The results indicated that the regimens with CCRT (cisplatin + etoposide), CCRT (carboplatin + paclitaxel), CCRT (pemetrexed + cisplatin), CCRT (S-1 + cisplatin), and CCRT (cisplatin + vinorelbine) had relatively better efficacies compared with other regimens. As for toxicities of different CCRT regimens, the CCRT (carboplatin + paclitaxel), CCRT (pemetrexed + cisplatin), and CCRT (docetaxel + cisplatin) were relatively lower.
CONCLUSIONS
Our study demonstrated that CCRT (pemetrexed + cisplatin) and CCRT (carboplatin + paclitaxel) might be the best options for the treatment of LA-NSCLC, and CCRT (pemetrexed + cisplatin) had the highest 3-year overall survival (OS) rate.

INTRODUCTION
Langerhans cell histiocytosis (LCH) is a rare disease that usually occurs in children <15 years of age. Adult-onset LCH is extremely rare. Previous published guidelines and studies mainly focused on pediatric patients. The rarity and also insufficient knowledge of LCH in adults, especially central neuvous system (CNS) involvement of LCH, often resulted in missed and delayed diagnosis.
CASE PRESENTATION
A 35-year-old woman presented with cognitive impairment, anxietydepression, decreased eyesight, skin rash, hypernatremia, gonadal hormone deficiency and hypothyroidism. She had experienced menstrual disturbance and infertility since 10 years ago. MRI examination showed a mass lesion in the hypothalamic-pituitary region. Sighs of radiologic neurodegeneration were not found on brain MRI scans, however. Biopsy of skin rash confirmed the the diagnosis of multisystem LCH. BRAF V600E mutation was detected in the peripheral blood mononuclear cells. She accepted combination chemotherapy of vindesine and prednisone and accquired partial remission. The patient died of severe pneumonia during the second course of chemotherapy.
CONCLUSION
Given the complicated differential diagnoses of neuroendocrine disorders, it was essential to be aware of CNS involvement of LCH at first, especially in adults. BRAF V600E mutation may participated in disease progression.

Cancer Medicine Mar 2024Blinatumomab early-line treatment in B-cell precursor acute lymphoblastic leukemia (B-ALL) might improve clinical outcomes.
BACKGROUND
Blinatumomab early-line treatment in B-cell precursor acute lymphoblastic leukemia (B-ALL) might improve clinical outcomes.
METHODS
We conducted a retrospective real-world cohort analysis in 20 newly diagnosed B-ALL patients who received reduced-dose chemotherapy (idarubicin, vindesine, and dexamethasone) for 1-3 weeks, followed by blinatumomab for 1-4 weeks as an induction therapy.
RESULTS
At the end of the induction therapy, a complete remission rate of 100% was achieved; 17 (85%) patients were minimal residual disease (MRD) negative (<1 × 10 ). Adverse events (AEs) were reported in 12 (60%) patients-43.8% were grade 1-2 and 56.2% were grade 3-4. No incidence of neurotoxicity or grade ≥3 cytokine release syndrome was reported.
CONCLUSIONS
Blinatumomab demonstrated a significant improvement in clinical outcomes in patients with newly diagnosed B-ALL irrespective of their poor-risk factor status and the pretreatment blast burden.

SSBP2-CSF1R is an important biomarker for clinical diagnosis and prognosis of Philadelphia chromosome-like acute lymphoblastic leukemia (Ph-like ALL). This case report presents a pediatric Ph-like ALL patient carrying the SSBP2-CSF1R fusion gene. The patient was resistant to most conventional chemotherapy regimens and to dasatinib, an inhibitor that has been reported to have a therapeutic effect on SSBP2-CSF1R fusion Ph-like ALL, as she remained minimal residual disease (MRD) positive (detection by flow cytometry) and SSBP2-CSF1R fusion gene (detection by RT-PCR) positive after five rounds of such regimens. We thus conducted a large-scale screening to assess the sensitivity of the patient's leukemic cells to anti-cancer drugs. Based on the susceptibility results, we chose to combine cytarabine, homoharringtonine, dexamethasone, fludarabine, vindesine, and epirubicin for treatment. Clinical results showed that after a course of treatment, both MRD and SSBP2-CSF1R fusion gene turned negative, and there was no recurrence during an 18-month follow-up. In conclusion, our study suggests that the SSBP2-CSF1R fusion gene may be an important biomarker of primary drug resistance in Ph-like ALL, and indicate that the combination of cytarabine, homoharringtonine, dexamethasone, fludarabine, vindesine, and epirubicin can achieve optimal therapeutic results in this category of patients.

In-Silico Mining of the Toxins Database (T3DB) towards Hunting Prospective Candidates as ABCB1 Inhibitors: Integrated Molecular Docking and Lipid Bilayer-Enhanced Molecular Dynamics Study.
Multidrug resistance (MDR) is one of the most problematic issues in chemotherapeutic carcinoma therapy. The ABCB1 transporter, a drug efflux pump overexpressed in cancer cells, has been thoroughly investigated for its association with MDR. Thus, discovering ABCB1 inhibitors can reverse the MDR in cancer cells. In the current work, a molecular docking technique was utilized for hunting the most prospective ABCB1 inhibitors from the Toxin and Toxin-Target Database (T3DB). Based on the docking computations, the most promising T3DB compounds complexed with the ABCB1 transporter were subjected to molecular dynamics (MD) simulations over 100 ns. Utilizing the MM-GBSA approach, the corresponding binding affinities were computed. Compared to ZQU (calc. -49.8 kcal/mol), Emamectin B1a (T3D1043), Emamectin B1b (T3D1044), Vincristine (T3D4016), Vinblastine (T3D4017), and Vindesine (T3D2479) complexed with ABCB1 transporter demonstrated outstanding binding affinities with Δ values of -93.0, -92.6, -93.8, -92.2, and -90.8 kcal/mol, respectively. The structural and energetic investigations confirmed the constancy of the identified T3DB compounds complexed with the ABCB1 transporter during the 100 ns MD course. To mimic the physiological conditions, MD simulations were conducted for those identified inhibitors complexed with ABCB1 transporter in the presence of a POPC membrane. These findings revealed that Emamectin B1a, Emamectin B1b, Vincristine, Vinblastine, and Vindesine are promising ABCB1 inhibitors that can reverse the MDR. Therefore, subjecting those compounds to further in-vitro and in-vivo investigations is worthwhile.

RATIONALE
Subcutaneous panniculitis like T-cell lymphoma (SPTCL) is a rare primary cutaneous lymphoma that belongs to peripheral T cell lymphomas, of which the overall prognosis is poor. Chidamide, a deacetylase inhibitor, has been approved for the treatment of peripheral T cell lymphomas. However, due to the rare occurrence of SPTCL, it is currently unknown whether Chidamide is effective for all SPTCL patients and whether there are molecular markers that can predict its therapeutic effect on SPTCL.
PATIENT CONCERNS AND DIAGNOSES
The patient was a sixteen-year-old male and underwent subcutaneous nodule biopsy which showed SPTCL. Next-generation sequencing revealed AT-rich interaction domain 1A (ARID1A) mutation, and positron emission tomography/computed tomography showed scattered subcutaneous fluorodeoxyglucose metabolic lesions throughout the body.
INTERVENTIONS AND OUTCOMES
During the first 3 CHOP (cyclophosphamide, doxorubicin, vindesine, and prednisone) treatment, the patient relapsed again after remission, and the successive addition of methotrexate and cyclosporine did not make the patient relapsing again. Then, after adding Chidamide to the last 3 CHOP treatment, the patient was relieved again. The patient underwent autologous hematopoietic stem cell transplantation (auto-HSCT) after completing a total of 8 cycles of chemotherapy, and continued maintenance therapy with Chidamide after auto-HSCT. Currently, the patient has been in continuous remission for 35 months.
LESSONS SUBSECTIONS
This case is the first report of a refractory/recurrent SPTCL with ARID1A mutation treated with Chidamide. The treatment of Chidamide on the basis of CHOP plus auto-HSCT therapy achieved good results, suggesting that ARID1A may act as a molecular marker to predict the therapeutic effect of Chidamide on SPTCL patients, which helps to improve the precision of SPTCL treatment and the overall prognosis of SPTCL patients.

Cardiac involvement in a patient with B-cell lymphoblastic lymphoma/acute lymphoblastic leukemia and a history of allogeneic hematopoietic stem cell transplantation and CAR T-cell therapy: A case report.
Cardiac involvement in hematological malignancies is uncommon, with only a few cases reported to date, and it often leads to a poor prognosis. Here, we report a case of a 42-year-old woman with a history of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and anti-CD19 chimeric antigen receptor (CAR) T-cell therapy for B-cell lymphoblastic lymphoma/acute lymphoblastic leukemia in whom cardiac mass and myocardial infiltration were detected. Prior to this presentation, massive pericardial effusion had occurred 6 months after CAR T-cell therapy, which was improved ultrasound-guided pericardiocentesis. We observed elevated cytokine levels and increased copy number of CAR DNA in both pericardial effusion and serum. Upon detecting cardiac mass and myocardial infiltration, the patient was administered tocilizumab (a humanized monoclonal antibody against IL-6 receptor), which controlled the serum cytokine levels, and reduced intensity chemotherapy, including vindesine, cyclophosphamide, and prednisolone. However, the patient finally died of multiple organ failure. To the best of our knowledge, this is the first report on the development of a cardiac mass and occurrence of myocardial infiltration after allo-HSCT and CAR T-cell therapy. This report may provide supporting data for the early diagnosis and immediate treatment of patients with cardiac involvement.

BACKGROUND
Mucosa-associated lymphoid tissue (MALT) lymphoma is an indolent B cell lymphoma. Its occurrence in the pleura is rare, with atypical clinical manifestations. MALT of the pleura is easily misdiagnosed. This is the first case report of pleural MALT lymphoma in China.
CASE DESCRIPTION
We report the case of a 54-year-old Chinese man with no notable medical history who complained of cough, sputum, and shortness of breath for 3 months. He had a positive purified protein derivative (PPD) test. An initial misdiagnosis of pleural tuberculosis was corrected, after 3 thoracoscopic biopsies and tests, to primary pleural MALT lymphoma. He received treatments of R-CHOP (rituximab, cyclophosphamide, epirubicin, vindesine and prednisolone) and traditional Chinese medicine. The patient was followed for 3 years until June 2022, with no obvious respiratory symptoms. Pleural MALT lymphoma is extremely rare, with only a few cases reported. This article describes our case, and includes an overview of 15 previously reported cases to summarize the characteristics, treatments, and prognosis of primary pleural MALT lymphoma.
CONCLUSIONS
Pleural MALT lymphoma is rare, and a correct diagnosis depends on tissue biopsy, immunohistochemical staining, and detection of gene rearrangement. Thoracoscopy is important to diagnose this disease. Multiple thoracoscopic biopsies may be necessary.

Coexistence of primary thyroid diffuse large B cell lymphoma and papillary thyroid carcinoma in a patient with Hashimoto's thyroiditis: a case report and literature review.
Papillary thyroid carcinoma (PTC) is the most common pathological type of thyroid malignancy and also has an excellent prognosis. Primary thyroid lymphoma (PTL) is rare and has a poor prognosis. The co-occurrence of both malignancies is extremely rare, and the preoperative diagnosis is rather difficult. We report the case of a patient with both PTC and PTL in the setting of Hashimoto's thyroiditis (HT). A 59-year-old female patient was referred to our department for progressive enlargement of the thyroid gland over a few months. The imaging results demonstrated an enlarged thyroid and a mass in the thyroid. Total thyroidectomy and bilateral central neck node dissection were conducted. The final diagnosis of the coexistence of thyroid diffuse large B cell lymphoma and PTC was confirmed by histopathology and immunohistochemistry. The patient received radiation therapy and six cycles of chemotherapy combined with targeted therapy, including rituximab, cyclophosphamide, doxorubicin, vindesine, and prednisone (R-CHOP). After 6 months of follow-up, neither tumor has recurred. It is important for physicians to keep PTL in mind for differential diagnosis in HT patients with sudden thyroid enlargement.

Observational Study
Non‑Hodgkin lymphoma (NHL) is a form of lymphoid malignancy, with diffuse large B cell lymphoma (DLBCL) being the most common NHL isoform. Approximately half of patients with DLBCL are successfully cured via first‑line Rituximab, Cyclophosphamide, Epirubicin, Vindesine, Prednisolone (R‑CHOP) treatment. However, 30‑40% of patients with DLBCL ultimately suffer from treatment‑refractory or relapsed disease. These patients often suffer from high mortality rates owing to a lack of suitable therapeutic options, and all patients are at a high risk of serious treatment‑associated dose‑dependent toxicity. As such, it is essential to develop novel treatments for NHL that are less toxic and more efficacious. Oncolytic Vaccinia virus (OVV) has shown promise as a means of treating numerous types of cancer. Gene therapy strategies further enhance OVV‑based therapy by improving tumor cell recognition and immune evasion. Beclin1 is an autophagy‑associated gene that, when upregulated, induces excess autophagy and cell death. The present study aimed to develop an OVV‑Beclin1 therapy capable of inducing autophagic tumor cell death. OVV‑Beclin1 was able to efficiently kill NHL cells and to increase the sensitivity of these cells to R‑CHOP, thereby decreasing the dose‑dependent toxic side effects associated with this chemotherapeutic regimen. The combination of OVV‑Beclin1 and R‑CHOP also significantly improved tumor growth inhibition and survival in a BALB/c murine model system owing to the synergistic induction of autophagic cell death. Together, these findings suggest that OVV‑Beclin1 infection can induce significant autophagic cell death in NHL, highlighting this as a novel means of inducing tumor cell death via a mechanism that is distinct from apoptosis and necrosis.
