Mantle cell lymphoma (MCL) is a rare B-cell lymphoma characterized by both the incurable nature of indolent lymphomas and the clinical course of aggressive lymphomas. The integration of high-dose cytosine arabinoside (Ara-C) and autologous hematopoietic stem cell transplantation (ASCT) has led to substantial improvement in the outcomes of MCL patients in the immunochemotherapy era. More recently, the widespread use of small molecule targeted agents, particularly Bruton tyrosine kinase inhibitor (BTKi), has re-shaped the therapeutic landscape of MCL patients and challenged the traditional role of high-dose Ara-C and ASCT. Novel immunotherapies including bi-specific antibodies and chimeric antigen receptor T-cell (CAR-T) therapy have emerged as important treatment options for MCL patients with relapsed or refractory disease. With advances in multi-omics profiling, the development of personalized, potentially curative strategies based on individual genetic and immune features is expected to become a major focus of future research on MCL. This article will delve into the latest research progress in the treatment and genetics and translational research on MCL patients, focusing on the latest progress of research on the treatment of newly diagnosed MCL patients, treatment of relapsed/refractory MCL patients, and the genetics and translational treatment of MCL patients, and explore the evolution and future direction of its treatment model.

OBJECTIVES

To report a case of triple primary malignant neoplasms in a 70-year-old woman diagnosed with follicular and papillary thyroid carcinoma and diffuse B-cell lymphoma of the right submandibular gland and cervical lymph nodes.

METHODS

Design:Case Report

Setting:Tertiary Government Training Hospital

Patient: One

RESULTS

A 70- year-old woman presented with a four-year history of gradually enlarging anterior neck mass, associated with a right submandibular mass and neck nodes for one year. The gradual progression of her symptoms made the patient think that it was a benign condition. This led to a delay in medical consultation. The patient underwent total thyroidectomy with functional neck dissection of the ipsilateral right neck. Histopathology revealed simultaneous follicular and papillary thyroid carcinoma, and diffuse B-cell lymphoma of the cervical lymph nodes. The patient was referred to medical oncology and nuclear medicine for further management.

CONCLUSION

Our patient was incidentally diagnosed with follicular and papillary thyroid carcinoma and diffuse B cell lymphoma of the cervical lymph nodes after surgery. Such triple primary malignant neoplasms in a single individual are rare, and as in our case, may only be diagnosed in hindsight.

BACKGROUND AND OBJECTIVES

Non-Hodgkin Lymphoma (NHL) ranks 11th in cancer incidence and mortality in the Philippines with the combination chemotherapy composed of Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) being commonly used as treatment. However, the addition of Rituximab to CHOP (R-CHOP) has been shown to exhibit higher response rates and longer remissions, potentially improving quality of life. Currently, there is conflicting evidence on the cost-utility of CHOP versus R-CHOP. The study aimed to describe the patient- and country-specific factors, and treatment modalities used for NHL and systematically review cost-utility evidence of R-CHOP versus CHOP in adult NHL patients.

METHODS

A systematic literature search of cost-utility studies on R-CHOP versus CHOP for NHL treatment was performed on eight databases: PubMed/MEDLINE, Scopus, Web of Science, EBSCOHost, Cochrane, York Research Database, Centre for Reviews and Dissemination Database, and HERDIN, where 607 studies were identified. Upon screening using an eligibility criteria, 10 studies were included and critically assessed using four appraisal tools: CHEERS, Drummond, Cooper, and ECOBIAS. These were performed independently by two authors with a third author assisting to help reach a consensus.

RESULTS

All studies from high-income countries (HICs) (n=8) and low-middle-income country (LMIC) (n=1) suggested that R-CHOP was more cost-effective for NHL treatment than CHOP in terms of utility outcomes. The study conducted in a low-income country (LIC) (n=1) suggested the opposite, favoring CHOP over R-CHOP. Methodological differences such as perspective, discount rate, willingness-to-pay (WTP), time horizon, and economic model were observed. Methodological limitations include completeness of data reported and credibility of sources used.

CONCLUSION

The results of this review shall be interpreted with caution as those favoring R-CHOP over CHOP for NHL treatment in terms of cost-utility were concentrated in HICs. More economic evaluations from LICs, LMICs, and upper-middle income countries (UMICs) are needed for a robust conclusion. Additionally, establishing a universally recognized guideline for economic evaluations is essential to guide researchers effectively.

(+)-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.

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 of malignant lymphoma of the head and neck in children, and to improve the understanding and diagnosis and treatment of this type of disease by otolaryngologists. Methods:Clinical data of 49 children with malignant lymphoma of the head and neck hospitalized in the Department of Otorhinolaryngology, Head and Neck Surgery of Kunming Children's Hospital from 2013-2021 were retrospectively analyzed and statistically analyzed according to gender, age distribution, duration of the disease, site of onset, type of pathology and survival status. Results:A total of 49 cases of malignant lymphoma of the head and neck in children were collected, of which, 39 were male and 10 female. The minimum age was 3 years, the maximum was 14 years and 4 months, the median age of onset was 7 years, and the largest percentage （51.02%） of children was in the school age（6-12 years）. The duration of the disease ranged from 5 days to 2 years, with a median of 1 month, and the site of the lesion was located in the neck in the majority of cases, 41（83.67%）. The pathologic types of hodgkin lymphoma（HL） were 25 cases（51.02%） and non-hodgkin lymphoma（NHL） were 24 cases（48.98%）, and among hodgkin lymphomas, mixed-cell classical hodgkin lymphoma was the most common, with 9 cases（18.37%）; among non-hodgkin lymphomas,originated from B-cells in 16 cases （32.65%） and from T-cells in 7 cases （14.29%）, with Burkitt's lymphoma being the most numerous of B-cell origin in 13 cases （26.53%）, and T-cell lymphoblastoid lymphoma being the most common of T-cell origin in 4 cases （8.16%）. The follow-up period was from 22 days to 6 years and 10 months, with 3 cases losing, 43 cases surviving, 3 cases dying, with a survival rate of 93 5%, and 3 cases relapsing, with a relapse rate of 6 5%. Conclusion:Children's head and neck malignant lymphoma has its own characteristics in terms of age of onset, gender distribution, site of onset, pathological type and treatment prognosis, which should be comprehensively assessed, diagnosed as early as possible, and multidisciplinary joint treatment actively carried out to propose personalized treatment plans.

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.

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.
