Lung cancer mass surveys are performed for the ultimate purpose of decreasing the death rate of lung cancer. Annual chest X-ray examinations are effective to detect the peripheral type of early stage lung cancer. On the other hand sputum cytology examination is effective for the detection of early stage lung cancer of central type. The relative rate of early stage lung cancer among the total number of lung cancers treated in Tokyo Medical College so far is 4.3%. is 3.7% until 1980 and 5.4% after then. Localization is then performed by fiberoptic bronchoscopy. The findings can be divided into two categories: protruding and superficial types. Tumor localization is sometimes very difficult in cases of early stage superficial squamous cell carcinoma such as carcinoma in situ. The authors developed excimer dye laser equipment for localization of early stage cancer such as cvarcinoma in situ using an excimer dye laser. Fluorescence was recognized in lesions, showing this equipment to be effective to localize even very small malignant lesions.

USEFULNESS OF CINE MR IMAGING IN EVAL-UATION OF CARDIO-VASCULAR INVASION OF LUNG CANCERS OR MEDIASTINAL TUMORS. Osada H.. Nakajima Y., Yokote K., Taira Y.. Kurisu S., and Yamate N. Dept. Surg. Div. III, St. Marianna Medical College, Kawasaki.. IJAPAN Purpose: An hypothesis was tested, that tine MR motion pictures could distinguish a noninvasion, from a questionable one. of z lung cancer or a meij.as-tinal tumor co ch:? heart or great vessels. :.:aterial ant Xet,loc;s: In 10 patients (6 lung cancer and 4 mediastinal tumor) in which a tumor invaion to the atrium or the great vessels was suspected on static CT/MR images, tine MR images were obtained per planes perpendicular to the interface in question, using a computer soft Cardiac Package,, incorporated to a Philips Gyroscan-Superconductive, 1.5T. When the motion picture showed either a transient low signal band through the interface or a pulsatile motion of the tumor with a phase different from that of the neighbouring cardiovascular structures, it was regarded as a sign of no-real-invasion.(Typical examples can be shown in a video). Xesults: Nine of 10 patients thus underwent surgery ana proved free i'rom invasion as expected. Conclusion: Cine ~1% images are valuable in picking up surgical candidates with possible cardio--vascular invasion of chest tumors.
