■胰腺导管腺癌(PDAC)占所有胰腺癌的90%。预后较差,全球5年生存率为2-9%。转移的程度是预后因素。最常见的转移部位包括肝脏,腹膜,肺,和骨头。我们报告一例PDAC向左脉络膜远处转移。
该患者是一名59岁的白人男性,最初表现为右侧腹部疼痛,进展为运动和活动障碍。腹部计算机断层扫描显示胰尾肿块随后通过内窥镜超声和细针抽吸术确认为PDAC。在开始治疗之前,患者因急性视力变化被转诊至眼科.评估显示,视网膜下液(SRF)上的左眼色素变化以及周边视网膜色素脱失,表明脉络膜转移。截至本报告提交,患者已经完成了最初6个月的吉西他滨/紫杉醇蛋白结合/顺铂治疗疗程,且部分缓解.他在第二线化疗中仍然活跃。视觉障碍和脉络膜转移的证据继续解决。
■PDAC通常在后期被识别,在80-85%的首次诊断中发现转移或局部进展。这被认为是其2至11个月的低中位生存期的原因。视网膜脉络膜是PDAC转移极为罕见的部位,文献报道的病例不到10例。在这个病人身上,脉络膜是第一个确诊的转移部位,代表远处转移.然而,该患者病情持续良好,预计在全身化疗后超过11个月的上限中位生存期.从这个案子来看,我们注意到治疗开始前的远处转移可能并不能预示更差的预后.全身化疗对原发性肿瘤缩小和脉络膜转移消退均有效,导致视觉症状的改善。这表明,虽然脉络膜转移不应在PDAC患者中遗漏,全身化疗可有效缓解侧支症状,从而维持生活质量.
UNASSIGNED: Pancreatic ductal adenocarcinoma (PDAC) accounts for 90% of all pancreatic carcinomas. Prognosis is poor with a worldwide five-year survival rate of 2-9%. Extent of metastasis is a prognostic factor. Most common metastatic sites include the liver, peritoneum, lung, and bones. We report a
case of distant metastasis of PDAC to the left
choroid.
UNASSIGNED: This patient is a 59-year-old Caucasian male who initially presented with right flank pain progressing to exercise and activity impairment. Abdominal computed tomography scan showed a pancreatic tail mass subsequently confirmed as PDAC via endoscopic ultrasound with fine needle aspiration. Prior to treatment initiation, patient was referred to ophthalmology for acute vision changes. Evaluation revealed left eye pigmentary changes overlying subretinal fluid (SRF) along with peripheral retinal depigmentation indicative of choroidal metastasis. As of this report submission, patient has completed his initial 6-month course of gemcitabine/paclitaxel protein-bound/cisplatin with partial response. He remains active on his second line of chemotherapy. Visual disturbances and evidence of choroidal metastasis continue to resolve.
UNASSIGNED: PDAC is often identified at a late stage, with metastasis or local advancement identified in 80-85% of first diagnoses. This is thought to account for its poor median survival of two to eleven months. The retinal
choroid is an extremely rare site of PDAC metastasis, with less than ten cases reported in literature. In this patient, the
choroid was the first confirmed metastatic site and represented distant metastasis. Nevertheless, this patient continues to do well and is expected to exceed the upper bound median survival of 11 months following systemic chemotherapy. From this
case, we note that distant metastasis prior to treatment initiation may not predict worse prognosis. Systemic chemotherapy was effective in both primary tumor shrinkage as well as regression of choroidal metastasis, leading to improvement in visual symptoms. This suggests that while choroidal metastasis should not be missed in patients with PDAC, systemic chemotherapy may be effective in mitigating collateral symptomatology and thus preserving quality of life.
