Detection of primary breast cancer presenting as metastatic carcinoma of unknown primary origin by 111In-pentetreotide scan.

Journal Article (Journal Article)

Women with isolated metastatic carcinoma or adenocarcinoma involving axillary lymph nodes are a well-recognized group of unknown primary carcinoma (UPC) patients with a favorable prognosis. This group of patients are generally treated based on the assumption that they have occult breast cancer. However, to facilitate patient access to the whole spectrum of therapies available for patients with breast cancer, including strategies involving the use of high-dose chemotherapy, a precise diagnosis is increasingly important. In this clinical case we report the detection of a primary breast cancer by 111In-pentetreotide scanning in a woman who presented with metastatic carcinoma in axillary nodes, no palpable breast lesion, a nondiagnostic mammogram, and negative breast ultrasonography. Previous outcomes analysis of patients with UPC have emphasized the value of identifying women with breast cancer. This report suggests that the 111In-pentetreotide scan can contribute specific, clinically useful information in the evaluation of women presenting with metastatic carcinoma in axillary nodes and an occult primary and deserves prospective study in women with UPC presenting with isolated axillary metastases.
