A 64-year-old male patient was diagnosed with rectal gastrointestinal stromal tumor(GIST)by prostate biopsy, because of high PSA. We considered that a radical operation was impossible because the tumor occupied the pelvis, and we suspected prostate invasion. After neoadjuvant chemotherapy(imatinib mesylate 400 mg/day), the tumor size was reduced(90×85 mm→60×50mm), and we could thus perform radical resection. The patient is currently receiving adjuvant chemotherapy (imatinib mesylate 400 mg/day), without recurrence.
一名64岁男性患者因前列腺特异性抗原（PSA）水平升高，经前列腺活检被诊断为直肠胃肠道间质瘤（GIST）。由于肿瘤占据盆腔且怀疑侵犯前列腺，我们认为无法进行根治性手术。新辅助化疗（甲磺酸伊马替尼400毫克/天）后，肿瘤大小缩小（90×85毫米→60×50毫米），因此我们得以进行根治性切除。该患者目前正在接受辅助化疗（甲磺酸伊马替尼400毫克/天），未出现复发。
