[A case of stage IV breast cancer with improved cancer pain using bevacizumab and paclitaxel].

A 65-year-old woman with a right breast tumor and right arm pain was seen in our hospital. She was diagnosed with scirrhous carcinoma (Stage IV, hormone receptor-positive, and HER2-negative) with pleural effusion and metastasis to the lung, liver, bone, and multiple lymph nodes.

A 59-year-old woman with an exudative, reddish bilateral breast tumor and dyspnea visited our hospital. She was diagnosed as having scirrhous carcinoma with metastasis to the liver and pleural effusion, designated as Stage IV, hormone receptor positive, and human epidermal growth factor receptor-2 (HER2) negative.

[A case of adult primitive neuroectodermal tumor(PNET)with multiple lung metastases effectively treated with ADM, IFM(AI)regimen].

The patient was a 48-year-old male with a right subclavicular tumor. The pathological diagnosis showed primitive neuroectodermal tumor(PNET)because of the rosette formation and the positive neurogenic marker.Radiation was administered at a total dose of 50 Gy, because surgical resection would induce the loss of right arm function.
