Response evaluation of carbon-ion radiotherapy poses a diagnostic challenge. Due to its functional aspects, fluorodeoxyglucose positron emission tomography (FDG/PET) has a role in the diagnosis of photon radiation therapy. In addition, several studies suggested that FDG/PET may be useful to select the optimal site for performing a diagnostic biopsy. Here, we report a 73-year-old female in which FDG/PET was effective in determining the recurrence of liposarcoma and the therapeutic effect. Based on the results of FDG/PET, we could make a pathologic definitive diagnosis and selectively performing carbon-ion radiotherapy for active tumors.

碳离子放射治疗的疗效评估带来了诊断挑战。由于其功能方面的原因，氟脱氧葡萄糖正电子发射断层扫描（FDG/PET）在光子放射治疗的诊断中发挥着作用。此外，多项研究表明，FDG/PET可能有助于选择进行诊断性活检的最佳部位。在此，我们报告一名73岁女性，其中FDG/PET在确定脂肪肉瘤的复发和治疗效果方面有效。基于FDG/PET的结果，我们能够做出病理确诊，并对活动性肿瘤选择性地进行碳离子放射治疗。
