Multiple primary neoplasms in association with prostate cancer in black and white patients.

The current study follows up the 983 patients who were diagnosed as having prostate cancer at the Columbia-Presbyterian Medical Center in New York City between 1970 and 1979 and of whom 106 (11.5%) developed a multiple primary malignant neoplasm (MPMN) in addition to their prostate cancer by January 1, 1986. Of the 283 black patients, 32 (11.

Epidural cord compression in association with genitourinary neoplasms.

The epidural compression secondary to genitourinary malignancies is relatively uncommon. Of 2118 patients who were diagnosed as having a genitourinary malignancy at the Columbia-Presbyterian Medical Center from 1970-1979, 21 are known to have developed an epidural cord compression by June 30, 1985 (16 from prostate, 1 from urinary bladder, and 4 from renal origin). The following items were reviewed in these 21 patients: age of the patient at diagnosis of the primary tumor; primary site of the genitourinary primary; time in months from the date of diagnosis of the genitourinary primary to the data of diagnosis of the spinal cord compression; methods of diagnosis; presenting symptoms and signs; treatment methods; and survival following the date of diagnosis of the compression.

Multiple primary tumors in association with prostatic cancer.

One hundred forty-six patients with clinically nonmetastatic carcinoma of the prostate were treated at Columbia-Presbyterian Medical Center from 1964 through 1976. Of these 146 patients, 24 (16.4%) had developed at least one additional primary cancer.
