Clinical observations suggestive of host defense against cancer are numerous. Among them, the most intriguing phenomenon is the "spontaneous regression" of metastatic disease after removal of the primary tumor. Spontaneous disappearance of a pulmonary metastasis of a carcinoma of the kidney following nephrectomy has been reported by several authors.1-3 It is also known that pulmonary metastases of chorio-carcinoma may disappear after removal of the primary tumor.4
