title: Radioisotope-guided surgical biopsy of costal metastases in breast cancer patients.
abstract: Radioisotope bone scanning is a sensitive indicator of metastatic disease. Localization of the hot spot for biopsy is difficult. Today, a hand-held gamma probe enables the surgeon intraoperatively to accomplish the localization procedure easily. As this technique is described in American literature exclusively, more recent European findings is presented here. During one month two patients were diagnosed with breast cancer. Bone scanning disclosed minor hot spots in the ribs. On the day of surgical biopsy the localization of the hot spots was guided by a gamma probe. For the biopsy a dermal punch biopsy needle was employed, and fine needle aspiration biopsies were also taken. The procedures were easy and completed within a few minutes. The post-operative courses were uneventful. In one patient, final histology showed malignancy in both biopsies. In the other patient, only the fine needle aspiration biopsy was malignant. The punch biopsy was abnormal, but did not contain malignant tissue. The gamma probe is an important tool in the performance of rib biopsies of nonpalpable lesions. The punch biopsy technique is simple and combined with fine needle aspiration biopsy the method has proven to be sensitive and accurate. The punch biopsy technique furthermore reduces the risk of postoperative pneumothorax.
