Hypoxia-Regulated CD44 and xCT Expression Contributes to Late Postoperative Epilepsy in Glioblastoma
Kusakabe K, Inoue A, Ohnishi T, Nakamura Y, Ohtsuka Y, Nishikawa M, et al.
Biomedicines . 2025 Feb; 13(2). PMID: 40002787
Background/objectives: Late epilepsy occurring in the late stage after glioblastoma (GBM) resection is suggested to be caused by increased extracellular glutamate (Glu). To elucidate the mechanism underlying postoperative late epilepsy,...

Three-dimensional amide proton transfer (APT) imaging appliable to navigation surgery can present comparable metabolic activity of glioblastoma to C-Methionine PET
Inoue A, Watanabe H, Kusakabe K, Nishikawa M, Ohtsuka S, Shiraishi Y, et al.
Acta Neurochir (Wien) . 2025 Feb; 167(1):49. PMID: 39969596
Background: Amide proton transfer (APT) imaging has been proposed as a technique to assess tumor metabolic activity. We have previously C-methionine positron emission tomography (C-Met-PET) can evaluate the metabolic activity...

Radiological and pathological findings of spinal intramedullary granular cell tumor
Inagaki R, Kohno D, Shigekawa S, Inoue A, Kitazawa R, Kunieda T
Surg Neurol Int . 2025 Feb; 16:28. PMID: 39926464
Background: Granular cell tumors (GCTs) are rare, usually benign, tumors with classic histomorphology. This tumor can occur throughout the body, but the spine is a distinctly rare location. Here, we...

A case of immunocompetent intracranial cryptococcoma in which intraoperative rapid pathological diagnosis and polymerase chain reaction led to early treatment: What to know to avoid misdiagnosis as brain tumor
Fujishita S, Inoue A, Watanabe H, Nishikawa M, Taniwaki M, Matsumoto S, et al.
Surg Neurol Int . 2024 Oct; 15:330. PMID: 39372983
Background: Cryptococcal infections of the central nervous system are infrequent in immunocompetent hosts and usually present as meningitis. However, a fungal mass called a cryptococcoma may form, requiring caution in...

Reliable intraoperative diagnostic methods for PCNSL: utility of combining intraoperative immunohistochemistry, cytology, and flow cytometry in achieving optimal treatment
Inoue A, Miyazaki Y, Watanabe H, Nishikawa M, Kusakabe K, Ohnishi T, et al.
Acta Neurol Belg . 2024 Sep; 125(1):99-108. PMID: 39306596
Background: Primary central nervous system lymphoma (PCNSL) is a rapidly growing malignant tumor that typically shows sensitivity to high-dose methotrexate-based chemotherapy. Rapid diagnosis and early chemotherapy are thus essential to...

Optimal treatment strategy for low-grade spinal cord astrocytoma: a retrospective, multicenter analysis by the Neurospinal Society of Japan
Shigekawa S, Inoue A, Endo T, Muto J, Inoue T, Kanematsu R, et al.
J Neurosurg Spine . 2024 Sep; 41(6):699-707. PMID: 39303310
Objective: Primary spinal cord gliomas are rare, and among these astrocytomas (WHO grade II) are much rarer. The optimal treatment strategy thus remains unclear. The authors conducted a multicenter study...

Essentials for early diagnosis of primary intramedullary spinal cord lymphoma. How to suspect primary intramedullary spinal cord lymphoma early and proceed to invasive biopsy? A case report and literature review
Shigekawa S, Inoue A, Miyazaki Y, Taniwaki M, Kanehisa K, Matsumoto S, et al.
Surg Neurol Int . 2024 Mar; 15:41. PMID: 38468650
Background: Primary intramedullary spinal cord lymphoma (PISCL) is an extremely rare condition. Early diagnosis is very difficult due to the nonspecific clinical and imaging findings. A biopsy is essential for...

Shorter survival time of adolescents and young adult patients than older adults with spinal cord glioblastoma: a multicenter study
Inoue T, Endo T, Muto J, Umebayashi D, Mitsuhara T, Shigekawa S, et al.
J Neurosurg Spine . 2023 Nov; 40(2):196-205. PMID: 37976504
Objective: Cancers in adolescents and young adults (AYAs) (age 15-39 years) often present with unique characteristics and poor outcomes. To date, spinal cord glioblastoma, a rare tumor, remains poorly understood...

Role of amide proton transfer imaging in maximizing tumor resection in malignant glioma: a possibility to take the place of C-methionine positron emission tomography
Inoue A, Watanabe H, Kusakabe K, Nishikawa M, Shiraishi Y, Taniwaki M, et al.
Neurosurg Rev . 2023 Nov; 46(1):294. PMID: 37925381
Background: Amide proton transfer (APT) imaging has been proposed as a technique to assess tumor metabolism. However, the relationship between APT imaging and other quantitative modalities including positron emission tomography...

Clinical Characteristics and Long-term Outcomes of Spinal Pilocytic Astrocytomas: A Multicenter Retrospective Study by the Neurospinal Society of Japan
Muto J, Murata H, Shigekawa S, Mitsuhara T, Umebayashi D, Kanematsu R, et al.
Neurospine . 2023 Oct; 20(3):774-782. PMID: 37798969
Objective: The characteristics, imaging features, long-term surgical outcomes, and recurrence rates of primary spinal pilocytic astrocytomas (PAs) have not been clarified owing to their rarity and limited reports. Thus, this...
