The Systemic Inflammation Response Index Efficiently Discriminates between the Failure Patterns of Patients with Isocitrate Dehydrogenase Wild-Type Glioblastoma Following Radiochemotherapy with FLAIR-Based Gross Tumor Volume Delineation.

Background/objectives: The objective of this study was to assess the connection between the systemic inflammation response index (SIRI) values and failure patterns of patients with IDH wild-type glioblastoma (GB) who underwent radiotherapy (RT) with FLAIR-based gross tumor volume (GTV) delineation.

Methods: Seventy-one patients who received RT at a dose of 60 Gy to the GTV and 50 Gy to the clinical target volume (CTV) and had documented recurrence were retrospectively analyzed. Each patient's maximum distance of recurrence (MDR) from the GTV was documented in whichever plane it extended the farthest.

Superficial Acral Fibromyxoma.

Superficial acral fibromyxoma is a rare, benign, slow-growing, soft-tissue tumor commonly located in the acral regions, with a predilection for the great toe, developing from the nail unit. Because of its nonspecific features and rarity, clinical diagnosis is difficult. In this article, we present a case of superficial acral fibromyxoma located in the nail unit with new dermatoscopic and radiologic findings that have not been previously reported in the literature.
