抄録 Docetaxel is a standard treatment for patients with advanced or recurrent breast cancer. The recommended dose is 60 to 100 mg/m2. Previous study have shown that the tumor response rates of patients who received docetaxel monotherapy at doses of 60, 75, and 100 mg/m2 were 22.1% , 23.3% , and 36.0% , respectively, and there was a significant relationship between the dose and response. In Europe and the United States, docetaxel is approved at a dose of 100 mg/m2, and Japanese guidelines also recommend a dose of 100 mg/m2. However, the approved dose in Japan is up to 75 mg/m2. We have launched a phase I trial evaluating 100 mg/m2 docetaxel in patients with advanced or relapsed breast cancer. The major eligibility criteria are as follows: age ≥20 years, pathologically diagnosed breast cancer, recurrent or advanced breast cancer, a good performance status, and HER2 [human epidermal growth factor receptor 2] negative. The primary endpoint is demonstrated safety of 100 mg/m2 docetaxel. This study will clarify whether 100mg/m2 docetaxel can be administrated safely in Japanese patients with advanced or recurrent breast cancer.

抄録 We evaluated the usefulness of preoperative 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) examinations to predict the pathological features in primary breast cancer. In particular, we evaluated the correlation between the maximum standardized uptake values (SUVmax) obtained by 18F-FDG PET/CT and the Ki67 expression in estrogen receptor (ER)-positive invasive ductal carcinoma (IDC). Primary IDC patients operated between March 2009 and July 2013 at Okayama University Hospital were enrolled. We evaluated the correlations between the SUVmax and age, postoperative pT, histological grade, lymph vascular invasion, status of hormone receptor, human epidermal growth factor receptor 2 (HER2), Ki67 expression and node status. The Ki67 expression was classified as high (>14%) versus low (<14%). We enrolled 138 patients with IDC. Their median SUVmax was 3.85 (range:0-52.57). In a univariate analysis, the SUVmax was significantly related to age, pT, histological grade, lymphovascular invasion, hormone receptor status, HER2 status, node status and Ki67. In the 113 patients with ER-positive IDC, there was a significant correlation between Ki67 and SUVmax (p=0.0030). The preoperative 18F-FDG PET/CT results of IDC patients had significant relationships with pathological status parameters. The determination of the preoperative SUVmax might help classify Luminal A and Luminal B patients among luminal-type breast cancer patients.

抄録  Introduction: The one-step nucleic acid amplification (OSNA) assay is a new method to detect sentinel lymph node (SLN) metastases using cytokeratin 19 (CK19) mRNA in early breast cancer. Here we retrospectively analyzed the advantages and disadvantages of the OSNA assay.  Methods: In a trial period, SLNs were divided into two sections, and we examined one side using the OSNA assay. The other side was examined by pathologists. After this period, we examined whole SLNs using only the OSNA assay. The patients with positive nodes by OSNA assay and/or pathology required axillary dissection.  Results: We examined 27 primary breast cancer patients (36 SLNs) during the trial period. The overall concordance rate between the OSNA assay and pathology results was 91%. In the later period, 157 patients (217 SLNs) were examined. The CK19-positive rate obtained by the OSNA assay was 16.5% (macrometastases OSNA (++) : 7.2%, micrometastases OSNA (+) : 9.2%). The non-SLN positive rate among the CK19-positivecases was 23%. The OSNA assay's false negative was one case in which the expression of CK-19 on the primary tumor and lymph node was not detected.  Conclusions: Our OSNA assay results were comparable to those obtained using a conventional pathological technique. Pathologists and laboratory technicians could save time and effort by using the OSNA assay when seeking the precise diagnosis during surgery.

抄録 A high mammographic breast density is considered to be a risk factor for breast cancer. However, only a small number of studies on the association between breast density and lifestyle have been performed. A cross-sectional study was performed using a survey with 29 questions on life history and lifestyle. The breast density on mammography was classified into 4 categories following the BI-RADS criteria. The subjects were 522 women with no medical history of breast cancer. The mean age was 53.3 years old. On multivariate analysis, only BMI was a significant factor determining breast density in premenopausal women (parameter estimate, -0.403;p value, 0.0005), and the density decreased as BMI rose. In postmenopausal women, BMI (parameter estimate, -0.196;p value, 0.0143) and number of deliveries (parameter estimate, -0.388;p value, 0.0186) were significant factors determining breast density;breast density decreased as BMI and number of deliveries increased. Only BMI and number of deliveries were identified as factors significantly influencing breast density. BMI was inversely correlated with breast density before and after menopause, whereas the influence of number of deliveries on breast density was significant only in postmenopausal women in their 50 and 60s.

抄録 Ectopic thymoma is considered to arise from ectopic thymus tissue deposited as a result of the abnormal mislocalization of thymus tissue during the embryonic stage. An 86-year-old man visited our hospital with chief complaints of hoarseness and a mass in his anterior neck. A preoperative needle biopsy of the mass did not yield a definitive diagnosis. A positron emission tomography (PET) study revealed heterogeneous accumulation of <sup>18</sup>F-fluorodeoxyglucose (FDG) in the tumor. The tumor, affecting the left sternocleidomastoid muscle, the recurrent laryngeal nerve, the internal carotid vein, and the brachiocephalic vein, was resected using a combination of a collar incision in the neck and a median incision in the sternum. Immunohistochemically, the tumor was diagnosed as an ectopic thymoma of the neck. To date, only a few cases of ectopic thymoma presenting with FDG accumulation have been reported. Our experience indicates that ectopic thymoma should be kept in mind during the differential diagnosis of neck tumors with FDG accumulation appearing on PET images.
