title: Detection of viral-like cores from the urine of patients with genito-urinary malignancies.
abstract: Simultaneous detection assays on the core structures derived from the cerebrospinal fluid samples of patients with various types of central nervous system tumors have demonstrated the feasibility of this technique in detecting some of the diagnostic features of RNA tumor viruses. Similar assays done on urine samples from patients iwth various types of tumors in their genitourinary tracts have shown that of the 18 such samples from tumor patients, 15 or 83% were found to be positive. The control samples consisted of three from patients with benign prostatic hypertrophy and four from normal persons. None of these gave a positive reaction. [3H]DNA probes synthesized from the core structures from them hybridized readily to their corresponding polysomal RNAs but no to control tissues. The densities of particles from these samples have been found to be 1.168 g/ml for bladder carcinoma and 1.165 for prostatic carcinoma, the same densities as those found RNA tumor viruses.
