RESUMEN
Several cases of hormone receptor-positive HER2-negative advanced and recurrent breast cancer treated with fulvestrant (FUL)were retrospectively investigated to assess the efficacy and safety of the treatment. FUL was administered to a total of 41 patients-33 with recurrent and 8 with Stage IV cancer-from January 2012 to September 2016. The median number of lines that used FUL was 3, the median time to treatment failure(TTF)was 7 months, the overall response rate(RR)was 19.5%, and the clinical benefit rate(CBR)was 53.6%. Our result was similar to those of the FIRST and the FALCON studies, which showed a decrease in RR after the fourth-line. With regard to RR, FUL seemed to provide better results at Cthird-lines of treatment. While a shorter TTF was seen in the cases with liver metastases, a longer TTF was seen in the cases with soft tissue metastases. Therefore, it may be helpful to consider the site of metastasis when predicting the effects of FUL.

A 75-years-old man was diagnosed with a cystic submucosal tumor of the middle body of the stomach and diffuse cystic malformation. Laparoscopic total gastrectomy was performed since a type II c gastric cancer was found at the lower body of the stomach after 1-year follow-up. Histopathological examination revealed mucosal adenocarcinoma with diffuse cystic malformation. Strict observation and appropriate treatment are needed for diffuse cystic malformation because of its significant carcinogenic rate.

Myoid hamartomas of the breast are extremely rare breast lesions, with a poorly understood pathogenesis. We describe the case of a 38-year-old premenopausal woman who presenting with a mass in the left breast. Mammography revealed an oval mass that was partly indistinct, and ultrasonography showed a hypoechoic mass with a slightly irregular margin. Bilateral breast dynamic magnetic resonance imaging was performed for a more detailed evaluation. The images showed rapid initial enhancement and a microlobulated margin. Because the suspicion of malignancy was strong at that time, core needle biopsy was performed. Histologically, the tumor was identified as fibroadenoma. A case of myoid hamartoma of the breast that proved difficult to diagnose is reported, and discussed with reference to the literature.
