A case of nonsecretory multiple myeloma is presented. Radiological findings and bone marrow examination provided the diagnosis. Bone scintigraphy showed metastatic pulmonary calcification, thus demonstrating the potential superiority to any other routine diagnostic modality in detection of visceral calcification.

The prognostic value of c-erbB-2 protein overexpression has been evaluated in 463 patients with operable breast cancer after a median follow-up of 66 months. Overexpression was observed in 99/463 (21%) of the breast tumors. It showed significant positive correlation to histological grade (p < 0.0001) and tumor size (p < 0.02). A relationship of borderline significance was observed between c-erbB-2 protein overexpression and negative or low estrogen receptor (ER) content. No significant correlation was found to lymph node involvement or proliferating tumor cell fraction as determined by the proliferating cell nuclear antigen (PCNA). After a median follow-up of 66 months (range 6 to 109 months), the overall survival of all patients amounted to 63%. Multivariate analysis revealed lymph node involvement, tumor size, histological grade, histological type, c-erbB-2 protein overexpression, progesterone receptor (PR) content, and oral contraceptive use as independent prognostic factors. In an univariate analysis, the overall survival amounted to 72% and 38% of tumor patients with negative and positive c-erbB-2 protein overexpression, respectively. The most significant finding is that c-erbB-2 overexpression has been recognized as an independent predictive factor in subsets of tumor patients who would be expected to have a generally poor prognosis, such as those indicating axillary lymph node involvement, large tumor size (> 2 cm), and PR negativity.
