The malignant biological behavior of breast cancer remains obscure on diagnostic images, although understanding the grade of such malignancy is important for selecting appropriate treatment. Therefore, malignancy grades in operable breast cancer were evaluated using positron emission tomography/computed tomography (PET/CT) in a multicenter setting. We(More)
Postoperative prognosis is better for hormonal receptor-positive breast cancer than for other phenotypes; however, there are no definitive predictive factors for relapse or survival. This study aimed to evaluate the maximum standardized uptake value (SUVmax) on (18)F-fluoro-2-deoxy-glucose positron emission tomography/computed tomography (FDG-PET/CT) and(More)
OBJECTIVE The 7-year follow-up of the US oncology 9735 trial demonstrated the superiority of TC [docetaxel (DTX)/cyclophosphamide (CPA)] to doxorubicin/CPA therapy. To introduce TC therapy in Japan, the verification of the safety and tolerability is essential. We performed a collaborative prospective safety study with Okayama University to introduce TC(More)
BACKGROUND It is extremely difficult to bring about a complete cure of metastatic breast cancer: the purpose of treatment is to prolong the patient's survival while maintaining their quality of life (QOL). The current retrospective study was conducted to find whether S-1, an orally administered 5-FU agent, can produce a therapeutic result in patients with(More)
PURPOSE To determine whether volume-based parameters on pretreatment (18)F-fluorodeoxyglucose positron emission tomography/computed tomography in breast cancer patients treated with mastectomy without adjuvant radiation therapy are predictive of recurrence. METHODS AND MATERIALS We retrospectively analyzed 93 patients with 1 to 3 positive axillary nodes(More)
Imaging diagnostic methods except for mammograms are not recommended for follow-up of postoperative breast cancer patients in order to detect small recurrences because of the poor survival improvement in earlier randomized trials. However, the use of new imaging modalities may improve survival by detection of small isolated regional lymph node recurrences(More)
It is well-known that tamoxifen increases the risk of endometrial cancer. Although metastasis to the uterus from breast cancer is uncommon, there have been some case reports on uterine metastasis. If an endometrial abnormality is detected, the differential diagnosis of whether the uterine tumor is metastatic or primary is very important to determine the(More)
Breast cancer metastases to the stomach are very rare. As characteristics of breast cancer metastases to the stomach, metastases of lobular carcinoma, mainly with signet ring cells, are frequently observed, and they are often difficult to distinguish from a primary gastric cancer with signet ring cells. Moreover, because no characteristic symptoms are shown(More)
Nanoparticle albumin-bound paclitaxel (nab-pacli-taxel) is currently approved in Japan for treatment of breast cancer. However, apart from phase I clinical trials, data regarding Japanese patients are scant. In the present study, the efficacy and safety of nab-paclitaxel therapy were retrospectively analyzed in 22 patients with advanced or metastatic breast(More)
BACKGROUND Endocrine therapy is the preferred systemic treatment for metastatic breast cancer to prolong disease control. Aromatase inhibitors (AIs) are becoming the first choice for postmenopausal patients with metastatic breast cancer. AIs are divided into non-steroidal and steroidal agents. METHODS We retrospectively analyzed 81 patients with(More)
