Abstract

High-grade serous ovarian cancer (HGSOC) is the most common type of epithelial ovarian cancer with insidious onset, rapid growth, and invasive spread. Here, we reported the diagnosis and treatment of a 53-year-old patient with a history of hysterectomy aided by the 68Ga-FAPI PET/MR scan. The patient was first presented to the local hospital with a lump on the left side of the neck with a biopsy suggesting metastatic cancer. Pelvic ultrasonography revealed two irregular masses. After admission, tumor markers, pathology consultation of the biopsy, and the 68Ga-FAPI PET/MR scan were administered. The biopsy of the lump suggested poorly differentiated adenocarcinoma and CA125 was elevated at 530.6 U/ml. The 68Ga-FAPI PET/MR scan showed several abnormal lymph nodes and two soft tissue masses with borders of dispersed restriction displaying internally uneven signals depicted by slightly elongated T1 and T2 signals within the pelvic cavity suggesting that pelvic mass could be the primary lesion. The patient received cytoreductive surgery including bilateral adnexectomy, omentectomy, and appendectomy. Post-surgical pathology suggested left and right HGSOC with left fallopian tube invasion. The patient completed six courses of first-line chemotherapy and remained progression-free for 14 months up to date. To conclude, 68Ga-FAPI PET/MR aids in primary tumor determination and tumor burden assessment and provides a guide for the management of late-stage HGSOC patients.

病例报告:68Ga-FAPI PET/MR 扫描辅助诊断和治疗晚期高级别浆液性卵巢癌。
高级别浆液性卵巢癌(HGSOC)是上皮性卵巢癌中最常见的一种,具有起病隐匿、生长迅速、浸润扩散等特点。在此,我们报告了通过 68Ga-FAPI PET/MR 扫描对一名有子宫切除史的 53 岁患者的诊断和治疗。患者最初因左侧颈部肿块就诊于当地医院,活检提示为转移性癌症。盆腔超声检查发现两个不规则肿块。入院后进行了肿瘤标志物检查、活检病理会诊和 68Ga-FAPI PET/MR 扫描。肿块活检提示为分化较差的腺癌,CA125升高至530.6 U/ml。68Ga-FAPI PET/MR 扫描显示多个异常淋巴结和两个软组织肿块,肿块边界呈分散限制性,内部信号不均匀,盆腔内的 T1 和 T2 信号略有拉长,表明盆腔肿块可能是原发病灶。患者接受了细胞切除手术,包括双侧附件切除术、卵巢切除术和阑尾切除术。术后病理结果显示,左右侧 HGSOC 均有左侧输卵管受侵。患者完成了六个疗程的一线化疗,至今已14个月无进展。总之,68Ga-FAPI PET/MR 有助于原发肿瘤的确定和肿瘤负荷的评估,并为晚期 HGSOC 患者的治疗提供指导。
