BACKGROUND To evaluate the impact of change in the hormone receptor (HR) status (HR status conversion) on the long-term outcomes of breast cancer patients treated with neoadjuvant chemotherapy (NAC). METHODS We investigated 368 patients for the HR status of their lesions before and after NAC. On the basis of the HR status and the use/non-use of endocrine(More)
BACKGROUND Leptomeningeal metastasis (LM) occurs in 4-15% of patients with solid tumors. Although the clinical outcomes in cancer patients have been improving recently, no standard treatment for LM has been established as yet. The purpose of this study was to identify the prognostic factors in patients with solid tumors with cytologically proven LM. (More)
BACKGROUND Although a pathologic complete response (pCR) after neoadjuvant chemotherapy is associated with favourable outcomes, a small proportion of patients with pCR have recurrence. This study was designed to identify factors predictive of recurrence in patients with pCR. METHODS A total of 449 breast cancer patients received neoadjuvant chemotherapy,(More)
BACKGROUND The purpose of this study was to determine whether brain metastases from HER2-positive breast cancer could be detected noninvasively using positron emission tomography (PET) with (64)Cu-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA)-trastuzumab. METHODS PET was performed on five patients with brain metastases from HER2-positive(More)
The aim of present study is to explore the immunohistochemical profiles of brain metastases from breast cancer. We retrospectively performed immunohistochemical staining for estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor type 2 (HER2/neu), and cytokeratin (CK) 5/6 in 29 patients with resected tumor specimens of(More)
BACKGROUND Trabectedin is a novel anticancer agent used to treat soft tissue sarcoma (STS). This phase I study of trabectedin was performed to determine the recommended dose for phase II studies in Japanese patients with STS. METHODS Patients who had STS refractory to, or who could not tolerate, anthracycline-based chemotherapy were enrolled. The starting(More)
Yolk sac tumor (YST) is a rare malignant tumor originating from germ cells. YST normally originates from the gonads, rarely occurring in extragonadal sites. We report a 35-year-old man with YST arising in the omentum, which is the first reported case of a primary YST of the omentum in an adult male. The patient presented to the community hospital with(More)
Carcinoma of unknown primary site (CUP) is rarely encountered in clinical practice and optimal chemotherapy has not yet been established. This phase II study was conducted to evaluate the efficacy and toxicity of combined irinotecan+carboplatin therapy in chemotherapy-naive patients with CUP. Irinotecan was administered at 60 mg m(-2) as a 90-min(More)
OBJECTIVE Although the implementation of routine screening for distress is desirable, doing so is difficult in today's busy clinical oncology practice. We developed the 'Distress Screening Program in Ambulatory Care' (DISPAC program) as a practical means of screening for and facilitating the treatment of major depression and adjustment disorders in cancer(More)
PURPOSE This was the first Phase I study to assess the safety and tolerability of the tablet formulation of olaparib (Lynparza™), an oral poly(ADP-ribose) polymerase inhibitor, in Japanese patients with advanced solid tumours. The pharmacokinetic profile and antitumour activity of olaparib tablets were also assessed. METHODS In this open-label,(More)
