[5-FU intra-arterial infusion and simultaneous irradiation in the treatment of esophageal cancer and metastatic lung cancer].
Precise 5-FU intra-arterial infusion and simultaneous irradiation are considered to reduce most tumors, with no functional disturbance occurring as a rule. We performed this therapy in 2 patients. One patient had lower esophageal cancer (T2N0M0) and the other had metastatic cancer of both lungs. We inserted a catheter into the lower periphery of the aortic arch via the left superficial temporal artery in the former patient, and into the upper thoracic aorta via the thyrocervical trunk in the latter patient, before infusing 5-FU together with simultaneous irradiation. Dysphagia disappeared and there was significant improvement of the esophagram, X-ray appearance, and endoscopic appearance in the former patient, who remains under observation. The latter patient showed remarkable regression of the tumor but died after a recurrence. Good efficacy is observed with the use of radiotherapy for the treatment of esophageal cancer at first. However, recurrences occur which carry a bad prognosis. The temporary favorable effect of radiotherapy suggests a promising future for this new therapy, since 5-FU is a strong radiosensitizer. We have a favorable impression of this mode of therapy in comparison with radiotherapy alone, though we have experience with only one patient. There was also a better response than expected when we used it for the treatment of metastatic lung cancer.
