过去用血卟啉衍生物作为荧光肿瘤标记物,检查早期肺癌;而由加拿大温哥华的Stephen Lam和Branko Palcic研制的检查早期肺癌和癌前病变的新试验装置可能证明它优于现有设备。它依靠人体组织的自体荧光,不是试验性药物。他们用被称为肺图荧光内 In the past, hematoporphyrin derivatives were used as fluorescent tumor markers to detect early lung cancer; and new test devices for early lung cancer and precancerous lesions developed by Stephen Lam and Branko Palcic in Vancouver, Canada, may prove superior to existing devices. It relies on autofluorescence of human tissues, not experimental drugs. They are used to be called Fluorescence Fluorescence
