BACKGROUND Combined use of blue dye and radiocolloid is considered to be useful for sentinel lymph node (SLN) biopsy of breast cancer. Whether both techniques together is superior to either alone was analyzed. PATIENTS AND METHODS A consecutive series of 308 cases of breast cancer who underwent SLN biopsy using the combination technique was used. The(More)
A critical elevation of povidone-iodine absorption which occurred in a burn patient who was topically treated with 10% povidone-iodine (PI) gel is herein reported. A 65-year-old man was admitted to our hospital for deep second- and third-degree burns covering 26% of his total body surface area. The intravenous administration with lactated Ringer's solution(More)
Aromatase inhibitors (AIs) were more effective than tamoxifen as a neoadjuvant endocrine therapy (NAE) for postmenopausal women with estrogen receptor (ER)-positive breast cancer. Neoadjuvant AIs were shown to reduce tumor volume and to allow the performance of breast-conserving surgery (BCS) in cases that would normally require mastectomy. Predictive(More)
We have investigated dihydropyrimidine dehydrogenase expression as a prognostic marker in breast cancer. A total of 119 women with breast cancer undergoing surgery between 1985 and 1996 were included in this study. Eighty-seven patients were treated with postoperative chemotherapy including 5-fluorouracil or 5-fluorouracil derivatives. Fifty-nine (50%) of(More)
Sentinel lymph node biopsy (SLNB) is standard care for patients with early-stage breast cancer, and axillary lymph node dissection (ALND) is considered unnecessary when sentinel lymph nodes (SLNs) are tumor-free. Additional non-SLN metastasis in patients with positive SLNs can be estimated using several risk factors such as primary tumor size, metastatic(More)
BACKGROUND It is currently unclear which patients with breast cancer with sentinel lymph node (SLN) metastases do not need axillary lymph node dissection (ALND). PATIENTS AND METHODS A cohort of 1,132 women who had unilateral invasive breast cancer with clinically negative nodes or nodes suspicious for metastasis, were intraoperatively diagnosed as having(More)
There is a growing recognition of discrepancies in myocardial temperatures during cold chemical cardioplegia. This study was designed to determine the extent to which coronary arterial stenosis just sufficient to abolish vasodilatory reserve in the working heart, but still compatible with myocardial viability ("critical stenosis"), limits heat transfer from(More)
BACKGROUND A regional nodal recurrence is a major concern after a sentinel lymph node biopsy (SLNB) alone in patients with breast cancer. In this study we investigated patterns and risk factors of regional nodal recurrence after SLNB alone. PATIENTS AND METHODS Between January 1999 and March 2005, a series of 1,704 consecutive breast cancer cases in 1,670(More)
We investigated dihydropyrimidine dehydrogenase (DPD) activity and its expression in breast cancer cases, and evaluated the prognostic significance of DPD expression in invasive breast cancer. A total of 49 paired of breast cancer tissues and the adjacent normal breast tissues were evaluated in this study. DPD expression of 191 patients with invasive breast(More)
Paclitaxel plus bevacizumab have shown a high response rate and prolonged progression-free survival in metastatic breast cancer patients. However, overall survival was not prolonged. Thus, no conclusion has been made on the effectiveness of bevacizumab. In our report, taxane plus bevacizumab were used to treat a metastatic breast cancer patient with taxane(More)
