PURPOSE: Sentinel lymph node biopsy (SLNB) in breast cancer patients with clinically negative axilla will ensure axillary dissection only for cases with lymph node metastasis and provide information about pathologic staging as accurate as the axillary dissection. It was shown that SLNB could be successfully performed regardless of the type of biopsy. The aim of this study was to investigate the feasibility of SLNB after excisional biopsy. METHODS: One hundred patients diagnosed with excisional biopsy or guide wire-localization and operated on with SLNB between February 2007 and March 2009 were retrospectively analyzed. SLNB was performed with 10 cc of 1% methylene blue alone or both methylene blue and 1 mCi of Tc-99m nanocolloid combination. Age, tumor localization and size, length of the biopsy incision, size of the biopsy specimen, multifocality, lymphovascular invasion, tumor grade, staining with methylene blue, localization, number and metastatic status of the lymph nodes stained, and success rate with a gamma probe were evaluated. RESULTS: Sentinel lymph node (SLN) could not be identified in 9 (16.9%) of patients in the methylene blue group (n=53). In the combination group (n=47), SLN could not be identified in one patient. Of 32 patients with negative SLNB, metastatic involvement was found to be present in 5 patients after axillary lymph node dissection (false negatives). The average numbers of SLNs found in the methylene blue group and combination group were 1.4 and 1.6, respectively. SLN detection and false negative rates in the methylene blue group were 83% and 15.7%, respectively. The rates for the combination group were 98% and 6.4%, respectively. None of the parameters related to patient, tumor or process were found to affect detection rates of SLN. CONCLUSION: Only SLNB using a combination method is a safe and reliable technique for breast cancer patients diagnosed with excisional biopsy.

PURPOSE: This study evaluated the importance of routine pathological examination of contralateral breast specimens in breast cancer patients using reduction mammoplasty. METHODS: Theweight of breast tissue resected from the contralateral breast in 71 patients and the number of slices used for pathological evaluation were recorded. Breast lesions found in the contralateral breast and accompanying lesions with tumors were examined. RESULTS: High risk proliferative lesions were reported in the contralateral breast of eight (11.2%) patients, and low-risk lesions were detected in 18 (25%). While the mean age of the patients with high-risk lesions was 45.6, it was 52.8 for the other patients (p=0.036). CONCLUSION: Bilateral reduction mammoplasty may be beneficial to delineate some pathologies in contralateral breasts even in those patients with normal clinical and radiological findings. The incidental discovery of these pathologies is much more likely in young breast cancer patients.

PURPOSE: Introducing the relationship between the surgical instruments used in modified radical mastectomy and wound complications is important for preventing and decreasing complications. This prospective randomized trial was designed to assess the impact of scalpel, electrocautery, and ultrasonic dissector usage on wound complications and tissue damage. METHODS: Eighty-two consecutive patients operated with mastectomy were studied. The postoperative time period needed for hemovac drainage, the amount and duration of seroma, infection, flap ecchymosis and necrosis rates were compared. Tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) levels in drainage fluids were determined to confirm the inflammatory response and tissue damage. RESULTS: The numbers of patients included in the scalpel, electrocautery and ultrasonic dissector groups were 27, 26, and 29, respectively. The groups were homogenous with respect to age, body mass index, stage, cormorbidities, breast volume and flap area. Operation time and the amount of bleeding were statistically higher in the scalpel group. The incidence of seroma was higher in the electrocautery group and arm mobilization had to be delayed in this group. There were no differences between groups with respect to hematoma, infection, ecchymosis, necrosis, hemovac drainage and the total and first 3 days of seroma volume. TNF-alpha and IL-6 levels were significantly higher in samples obtained from the drains of patients operated with electrocautery. CONCLUSION: Ultrasonic dissector decreases operation time by decreasing the amount of bleeding without increasing the seroma incidence. High cytokine levels in drainage fluids from patients operated with elecrocautery indicates that electrocautery induces more tissue damage and acute inflammatory response. Therefore, seroma, due to acute inflammatory response, was seen more frequently in the electrocautery group. Ultrasonic dissector coagulates protein by breaking hydrogen bonds which may close vascular and lymphatic channels more precisely. But, its actual preventive effect on seroma formation might be related to diminished inflammatory response.
