Summary: Novel boron-containing carbon dots (BCDs) were designed and prepared for boron neutron capture therapy (BNCT), encapsulated in exosomes (Exos) from macrophages to form BCD-Exos, achieving excellent therapeutic effects on brain glioma in mice models with 100% survival rate. Adjusted biodistribution of boron, enhanced T/N ratios, and precise match between boron and neutron exposure at the tumor site in vivo with fluorescence imaging of BCD-Exos contributed to the success of the treatment.

Summary: For IDH-mutant gliomas, there is still confusion on how to conduct long-term surveillance and imaging follow-up. Existing guidelines do not clearly specify individualized imaging guidelines based on treatment and tumor recurrence. In this study, we review current knowledge and propose recommended MRI surveillance intervals, as well as summarize situations where additional imaging studies may be advisable outside of the specified intervals.

Summary: WHO grade II-III gliomas are rare primary brain tumors with longer median survival compared to grade IV glioblastoma. Treatment involves maximal safe resection and adjuvant therapies, with challenges in conducting clinical trials due to rarity and long follow-up times. The 2016 WHO Classification introduced a molecular diagnostic framework for more homogenous subgroups. Available evidence for adjuvant treatment was generated pre-molecular era, emphasizing the need for further research in this field.

Summary: In this study, a novel boron agent, PBC-IP, was developed for efficient targeting and accumulation in glioblastoma cells. PBC-IP showed higher accumulation and tumor growth suppression compared to L-4-boronophenylalanine (BPA) in animal models. When delivered via convection-enhanced delivery (CED), PBC-IP achieved high tumor accumulation and significantly improved survival rate in the glioma model.

Summary: For patients with anaplastic oligodendroglioma, initial treatment with adjuvant chemotherapy alone, rather than radiation and chemotherapy, may be a viable option as it is associated with similar overall survival despite shorter progression free survival. Balancing longevity against radiation toxicity is crucial in determining the most suitable treatment approach.

Summary: In this study, multifunctional high boron content MOFs nano-co-crystals were fabricated for precise boron neutron capture therapy (BNCT) of brain glioma. The co-crystals exhibited excellent stability, superior colloid dispersion, and excellent biocompatibility. They could cross the blood-brain barrier, selectively target brain tumors, and deliver a high boron dose. Additionally, the co-crystals had intrinsic fluorescence and Zr-89 positron emission tomography imaging capabilities, enabling accurate tracking and quantification in vitro and in vivo. The combination of precise spatial-temporal imaging and BNCT achieved significant antitumor efficacy in glioma.

Summary: This study investigated the efficacy of ALA-PDT in destructing GSCs, including the MES-GSCs which have the lowest sensitivity to radiotherapy and chemotherapy. The results showed that ALA-PDT was effective against all GSC lines, and MES-GSCs exhibited higher PpIX expression than DGCs. Surviving MES-GSCs had lower stem cell marker expression and tumor forming potential. Thus, ALA-PDT may be clinically effective against HGG by targeting GSCs, including MES-GSCs.

Summary: The objective of this study was to verify the safety of spine surgery for late-stage elderly (65-74 years) compared to early-stage elderly (65-74 years). Through a retrospective multicenter study, it was found that although reoperation during hospitalization and length of hospital stay were higher in the late-stage elderly group, there were no significant differences in postoperative complications or activities of daily living at discharge compared to the early-stage elderly group. Therefore, spine surgery can be safely performed for late-stage elderly patients if perioperative risk factors are appropriately managed.

Summary: The aim of this study was to evaluate the influence of skin distortion due to surgical positioning on the clinical accuracy of the navigation system. The automatic intraoperative registration (AIR) method showed higher accuracy and smaller distance errors compared to the surface-merge registration (SMR) method. The AIR method was recommended for all surgical positions if intraoperative imaging was available, while the SMR method was only recommended for the supine position.

Summary: In recent years, boron neutron capture therapy (BNCT) has been studied as a potential treatment for high-grade gliomas. In this study, the feasibility of using a boron compound, DPA-BSTPG, targeting the 18 kDa translocator protein (TSPO), was investigated. The results showed that BNCT using a combination of DPA-BSTPG and BPA could provide multi-targeted neutron capture therapy, leading to longer survival times in experimental glioma models.

Summary: A novel boron-10 carrier containing MID, serum albumin as a drug delivery system, and cRGD targeting integrin Alpha(v)Beta(3) was developed. The efficacy of BNCT targeting integrin Alpha(v)Beta(3) using cRGD-MID-AC was evaluated in glioma cells in a rat brain tumor model. The results showed that cRGD-MID-AC had a similar cell-killing effect to BPA in vitro and accumulated in the brain tumor after intravenous administration. Furthermore, BNCT using cRGD-MID-AC significantly prolonged survival and resulted in long-term survivors.

Summary: There is limited research on the use of boron neutron capture therapy (BNCT) for cervical cancer. This study investigated the distribution of boronophenylalanine (BPA) and the effectiveness of BNCT on cervical cancer cell lines. Exposure to BPA and neutron irradiation resulted in a decrease in survival fraction compared to irradiation alone. In vivo experiments showed that the concentration of boron in cervical cancer tumors was highest 2.5 hours after intraperitoneal administration of BPA, and higher than in other organs. BNCT may be a promising treatment for cervical carcinoma.

Summary: This case report describes a patient with lymph node metastasis from glioblastoma who was asymptomatic but exhibited gradually increasing C-reactive protein levels before developing fever. Diagnosis of the lymph node metastasis was delayed due to fever of unknown origin, absence of infection signs, and no recurrence of the primary intracranial tumor. Chest computed tomography revealed lymphadenopathy, and biopsy confirmed glioblastoma lymph node metastasis. This is the fifth reported case of lymph node metastasis without intracranial recurrence.
