Metastatic orbital tumors.

A review was made of the clinical data of 28 patients with metastatic orbital disease diagnosed in our clinic between 1972 and 1993. Fifteen were men and 13 were women. The average age at diagnosis was 58.7 years. The right orbit was involved in 12 and the left orbit in 14 cases. Two cases had bilateral orbital involvement. Breast carcinoma was the most frequent tumor (8 of 28, 28.6%) followed by neuroblastoma (7 of 28, 25.0%), lung carcinoma (6 of 28, 21.4%), prostate carcinoma (3 of 28, 10.7%), gastrointestinal carcinoma (2 of 28, 7.1%), renal cell carcinoma and thyroid carcinoma (1 of 28, 3.6% each). Proptosis (67.9%), motility disturbance (57.1%) and mass (50.0%) were the three most common presenting signs. Enophthalmos was noted in two cases with breast carcinoma. Nine cases presented with ophthalmic signs and metastatic tumor was recognized later. In the remaining 19 cases, the diagnosis of the primary tumor preceded the onset of orbital metastasis. The time interval between the detection of the primary malignancy and metastatic orbital tumor was shortest for lung carcinoma (mean: 2 months) and longest for breast carcinoma (mean: 34 months). Radiotherapy and chemotherapy were applied in 12 cases. Improvement in orbital signs and visual acuity was noted in 5 cases. Radiotherapy, chemotherapy and hormonal therapy were used in 8 patients and improvement in orbital signs was noted in 4 of these patients. Four of 28 patients (2 with breast carcinomas, one with prostate carcinoma and one with thyroid carcinoma) survived longer than 5 years.(ABSTRACT TRUNCATED AT 250 WORDS)
