Immunohistochemical determination of estrogen and progesterone receptor content in human breast cancer
Immunohistochemistry of Estrogen Receptor (ER) and Progesterone Receptor (PR) has been performed in 687 cases of human breast cancer. The staining results have been compared by (1) computer-assisted image analysis (QIC Score) and (2) subjective grading of the cryostat sections ("German" IRS). Tumors without or with only weak ER or PR content may be distinguished by both methods from tumors with a high receptor content. The QIC Score values belonging to the intermediate IRS grades are distributed over a wide range, but no negative cases were found in these categories. It is concluded from our results that subjective grading of the slides is a simple, rapid and useful method for the determina…
Follow-up of patients with colonic polyps containing severe atypia and invasive carcinoma. Compliance, recurrence, and survival
Between January 1975 and December 1984 1769 polyps were endoscopically removed from 1219 patients. Eight percent of these patients had polyps containing severe atypia and 5.0% had polyps containing invasive cancer. A close postoperative surveillance program was followed by only a few patients, but compliance improved with longer follow-up intervals. Metachronous polyps were observed with similar frequency in patients with benign polyps (34.8%) and those with polyps containing severe atypia (23.8%) or cancer (41.7%). Patients in whom malignant polyps were endoscopically removed had a 5-year survival rate of 84.3% that did not differ from that of patients' whose polyps contained severe atypia…
