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)
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)
BACKGROUND It is still controversial whether axillary lymph node (ALN) dissection (ALND) can be omitted after negative sentinel lymph node (SLN) biopsy (SLNB) in breast cancer (BC) patients with clinically positive ALNs at presentation treated with neoadjuvant chemotherapy (NAC). The study aim was to analyze whether SLNB could be useful in these patients.(More)
BACKGROUND Sentinel lymph node biopsy (SLNB) is an important treatment option for breast cancer patients, as it can accurately predict axillary status. Our previous study using dye with or without radioisotope showed the accuracy and sensitivity of SLNB to be 97% and 94%, respectively. Based on these results, axillary lymph node dissection (ALND) was(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)
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)
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)
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)
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)
This study evaluated the possibility and efficacy of laser welding in biologic vascular grafts. Grafts were anastomosed to 21 canine peripheral (femoral and/or carotid) arteries or coronary arteries with a Nd-YAG laser using the contact method. The laser welds were fashioned using 1-1.5 W power for 1-3 sec. The grafts used were heparinized canine carotid(More)
