  10月7~9日,由北京大学临床肿瘤学院主办的燕京肿瘤临床与PET/CT应用会议在北京召开。

  会上,北京肿瘤医院的季加孚教授报告了PET/CT在胃癌诊治中的现状与展望。

  季教授指出,PET/CT对胃癌远处转移的诊断具有良好的特异性,但在T1期肿瘤及区域淋巴结转移的诊断方面应用价值有限。

  PET/CT对于胃癌复发的诊断具有良好的应用价值,但仍有局限性,如早期癌及非粘液性癌复发的假阴性问题。

  由于PET/CT可比CT更早地发现治疗后肿瘤组织的变化,因此可用于胃癌新辅助治疗的疗效评价,但是,炎症会导致假阳性、如何选择最佳评估时间点以及疗效评价标准等问题导致这种方法存在局限性。

  PET/CT并不是胃癌筛查的有效手段,胃癌筛查仍应以内镜及其他传统检查方式作为常规手段。

  今后应进一步探索PET/CT用于疗效监测的时间频度,挖掘SUV值在预后预测方面的临床应用价值,探索PET/CT在胃癌复发早期诊断方面的应用能否改善患者预后,并探索PET/CT评价胃癌疗效的时间和标准等问题。
