Hiroshi Kobayashi教授の研究室は、がん治療におけるバイオマーカーの評価と個別化医療の実現を目指しており、特に腫瘍の予後予測や治療反応のバイオインformat的解析に注力しています。ROS測定法のばらつきを解明する研究や、軟部肉腫の予後因子、神経芽腫様肉腫（MPNST）におけるNTRK遺伝子再配列の同定など、臨床的意義の高い分子標的治療の可能性を追求しています。また、画像誘導手術や腫瘍の生物学的特性解明を通じて、患者の生活機能を損なわず治療を実現する戦略の開発を進めています。

A total of 28 donor semen samples were used to evaluate the characteristics of laboratory variability in measuring reactive oxygen species (ROS). The objectives of this study were to assess the interassay (same sample observed on different days by the same observers) variability; interdonor, intraobserver (replications of the same sample on the same day) variability; and interobserver (multiple observers on the same day with the same sample) variability of the luminol-dependent chemiluminescence
Initial trabectedin at 1.2 mg/m<sup>2</sup> has clinically meaningful benefits for patients with L-sarcoma and certain histological subtypes of TRS.
Navigation-assisted surgery using a 3D fluoroscopy-based navigation system is effective for tumors in patients with TIO.
Malignant fungating wounds in soft tissue sarcoma were significantly associated with a poor prognosis; however, the incidence of surgical complications and local recurrence after limb-salvage surgery was comparable to that of general soft tissue sarcoma cases. Limb-salvage surgery should be considered, if possible, to preserve the patient's quality of life because of the dismal prognosis of patients with malignant fungating wound in soft tissue sarcoma.
The prognostic factors in patients with metastatic soft tissue sarcoma at diagnosis are generally similar to those in patients with localized disease. The overall survival in patients differed significantly according to histologic subtype. Surgical resection of primary lesions, especially those with a wide margin, may be an independent prognostic factor. Further studies are needed identify which subgroup of patients would benefit the most from primary lesion surgery.
Neurotropic tropomyosin receptor kinase (NTRK) gene rearrangements have been reported in limited cases of sarcomas; however, to date, there has been only one report of such rearrangements in malignant peripheral nerve sheath tumors (MPNSTs). Herein, we describe a 51-year-old male patient with a buttock tumor arising from the sciatic nerve, which was diagnosed as MPNST with positive S-100 staining, negative SOX10 staining, and loss of trimethylation at lysine 27 of histone H3 (H3K27me3) confirmed
