AbstractAbstract PDF
Prophylactic central neck dissection (CND) in clinically node-negative (cN0) papillary thyroid carcinoma (PTC) remains controversial. The purpose of this study was to evaluate the benefits of prophylactic ipsilateral CND compared with bilateral CND in total thyroidectomy for cN0 unilateral PTC.
We retrospectively enrolled 174 patients who underwent total thyroidectomies with prophylactic CND for cN0 unilateral PTC between January 2009 and May 2010. The prophylactic CND patients were divided into group 1, the ipsilateral CND group (n=74), and group 2, the bilateral CND group (n=100). The incidence of central lymph node metastasis (CLNM) and postoperative complications, such as hypoparathyroidism, recurrent laryngeal nerve injury, and recurrence were assessed.
CLNM was found in 22 (29.8%) in group 1 and 69 (69%) in group 2. The incidence of postoperative severe hypocalcemia less than 7.0 was also significantly different (six patients [8.1%] in group 1 and 23 [23%] in group 2; p=0.009). Permanent hypoparathyroidism was significantly more frequent in group 2 (4.1% vs. 19%; p=0.005). However, the incidence of transient hypoparathyroidism, recurrence, and recurrent laryngeal nerve injury was not significantly different.
Prophylactic ipsilateral CND has advantage not only to reduce incidence of some complications but also to have similar recurrence rate compared with bilateral CND. We suggest that prophylactic ipsilateral CND may be safe and effective for selected patients undergoing total thyroidectomy for cN0 unilateral PTC.

AbstractAbstract PDF
It has been reported that estrogen receptor beta (ERbeta) mRNA expression was down-regulated during carcinogenesis and was inversely related to estrogen receptor alpha (ERalpha) expression in breast cancer. The association of ERbeta mRNA expression to tamoxifen resistance has also been reported. In this study, the expression of ERalpha and ERbeta via immunohistochemistry (IHC) and reverse transcription-polymerase chain reaction (RT-PCR) was prompted, and an attempt was made to find out the relationship between ERbeta expression and recurrence in the hormonal therapy group, and between ERbeta expression and known prognostic factors. METHODS: Tumor specimens were obtained at surgery from 67 female breast cancer patients during the period of September 1995 to December 2000. All the specimens were frozen in liquid nitrogen and kept at -70degrees C until they were used. The medical records were analyzed retrospectively. The expressions of ER were analyzed using IHC and RT-PCR methods. RESULTS: The median follow-up was at 93.0 months (range: 14-157 months). The percentage of ERalpha+/ERbeta+, ERalpha+/ERbeta-, ERalpha-/ERbeta+, and ERalpha-/ERbeta group were 35.9% 9.4%, 47.2%, and 7.5%, respectively, in 53 patients with hormonal therapy. ERbeta was positive in 42 (82.3%) of 51 ER-positive patients. In the hormonal therapy group, the recurrence rates of each group was 15.8%, 0%, 40.0%, and 0%, respectively. In this group, the ERbeta expression tended to recur, but there was no clinical significance (p=0.084). CONCLUSION: The ERbeta expression may be a predictive marker of a poor response to endocrine therapy in breast cancer patients, although this needs to be confirmed in additional studies.

AbstractAbstract PDF
Adenoid cystic carcinoma (ACC) is a rare malignant neoplasm of the breast accounting for approximately 0.1% of all breast carcinomas with a total 200 cases reported in the literature. In contrast to the aggressive nature of ACC in other organs, ACC of the breast is known to have an excellent prognosis. Recently we experienced the first case of ACC of the breast at Yeungnam University hospital. The case was diagnosed by preoperative fine needle aspiration cytology. We report a case of ACC of the breast managed with breast conserving surgery and review the literature.
