The common bile duct and the duct of Wirsung cojoin at the level of the duodenum, forming the major. papilla of Vater. Existence of a double major papilla, i.e., two neighboring independent papillary structure:, is infrequent. In our endoscopy unit we have experienced one case of double papilla of Vater wherein canulation of the common bile duct and pancreatic duct could be accom plished through either orifice independently.

PURPOSE: Intraductal papilloma (IDP) is a benign breast disease with malignant potential, for which complete surgical excision is usually recommended. The aim of the present study was to investigate predictive factors for upgrading patients with a benign papillary lesion (BPL). METHODS: This study was an observational study using a prospectively collected cohort. In total, 13,049 patients who underwent a core needle biopsy (CNB) for a breast lesion between January 2009 and May 2015 were enrolled. We reviewed all patients with pathologically confirmed BPL from a CNB. RESULTS: Surgical treatment was performed for 363 out of a total of 592 lesions. According to the pathological differences, the lowest upgrade rate was shown in IDP without atypia (without atypia, 6.0%; with atypia, 26.8%; papillary neoplasm, 31.5%; p<0.001). The univariate analysis showed that, in IDP without atypia, the age at diagnosis, size of BPL on ultrasonography, and density on mammography were associated with upgrading. The multivariate analysis revealed that age >54 years and lesion size >1 cm were significantly associated with upgrade to malignancy (odds ratio [OR]=4.351, p=0.005 and OR=4.236, p=0.001, respectively). CONCLUSION: The indications for surgical treatment can be defined as age >54 years and mass size >1 cm, even in IDP without atypia in the CNB results; this also includes cases of IDP with atypia or papillary neoplasm. Therefore, we suggest that close observation without surgery is sufficient for younger women with a small IDP without atypia.

PURPOSE: The rate of malignancy in the follicular neoplasm (FN) or Hürthle cell neoplasm (HCN) of the thyroid gland is estimated as approximately 20~30%. Fine-needle aspiration biopsy (FNAB) and frozen section examination are restricted in differentiating between benign and malignant. The aims of this study are to compare the differences of clinicopathologic features and to determine the risk factors for malignancy in patients with FN or HCN. METHODS: A retrospective study was conducted of patients with FN or HCN who were diagnosed by FNAB, and underwent surgery at our institution between Jan. 2005 to Jun. 2010. We analyzed the risk factors for malignancy and the differences of clinicopathologic features in patients with FN or HCN. RESULTS: A total of 290 patients were enrolledin this study; 160 (55.2%) patients underwent thyroidectomy, 97 (60.6%) patients had FN, and 63 (39.4%) had HCN. Forty one (25.6%) patients were diagnosed as malignancy of these, 22 (22.7%) patients were FN and 19 (30.2%) were HCN (P=0.29). Two (2.1%) patients with FN and 10 (15.9%) with HCN (P=0.002) comcomitant papillary thyroid carcinoma were indentified by FNAB. Classification of nodules according to ultrasonographic findings in both neoplasms (P<0.05) and galectin-3 in FN (P<0.05) were predictive factors for malignancy. In addition, galectin-3 was a predictive factor for malignancy in indeterminate nodules on ultrasonography (USG) (P=0.028). CONCLUSION: Classification of nodules according to ultrasonographic findings and galectin-3 expression is helpful in predicting carcinoma of patients with FN or HCN.

PURPOSE: This assesses the current workings of multidisciplinary team (MDT) meetings across Korea through surgeons' reports and their current commitments to MDT meetings pertaining to breast cancer, and to determine any perceived areas of potential improvement. METHODS: A questionnaire was sent out to 307 members of The Korean Breast Cancer Society (KBCS) who worked at comprehensive or university medical centers in Korea. The mailing lists of the KBCS members were obtained with the approval of the society. From December 2008 to February 2009, the survey was distributed by surface and electronic mail, with an initial mailing followed by another distribution to non-responders eight weeks later. RESULTS: Sixty-five individuals (21.2%) returned the completed survey. Of these, 38 responders (62.3%) participated in MDT meetings. Most (97.4%) breast health specialists regarded MDT meetings as an effective method for treatment planning. Most responders (94.7%) reported that the MDT leader was a breast surgeon. CONCLUSION: The MDT approach is perceived as an effective method for breast cancer treatment planning and is a feature in most major centers in Korea. Further work is needed to ensure that the MDT approach operates as intended and that all breast cancer patients have access to an MDT.

PURPOSE: In breast cancer, response to endocrine therapy depends on estrogen receptor and progesterone receptor status. However, poor prognosis is conferred on patients with hormone receptor (HR)-positive breast cancer. We aimed to examine weakly positive HR breast cancer by comparing weakly positive HR to strongly positive HR and negative HR breast cancer. METHODS: We examined the clinical and biological features of 1,496 women with breast cancer, and these patients were categorized according to HR status as weakly positive, strongly positive, and negative HR breast cancer. RESULTS: In this study, among 1,496 patients with breast cancer, negative HR breast cancer was found in 374, weakly positive HR breast cancer in 90 and strongly positive HR breast cancer in 1,032 patients. Our multivariate analysis showed that there were differences in T stage, tumor-node-metastasis stage, vascular invasion, histologic grade and type, and Ki-67 index. Patients with weakly positive HR breast cancer had an increased risk of death and recurrence compared with those with strongly positive HR breast cancer and had similar prognosis as patients with negative HR breast cancer. CONCLUSION: Patients with weakly positive HR breast cancer received endocrine therapy because they were regarded as having positive HR breast cancer. However, their prognosis of overall survival and relapse-free survival was similar to that in patients with negative HR breast cancer. Therefore, we need to closely observe and consider active treatment for patients with weakly positive breast cancer.

PURPOSE: To evaluate clinical characteristics and the macular gradient in myopic posterior staphyloma with time domain (TD) optical coherence tomography (OCT). METHODS: Sixty-four staphyloma eyes of 40 patients were examined. Macular gradient (tangent theta) and the location of staphyloma were assessed with OCT imaging. The macular gradient was measured at points 1 mm and 2 mm distant from the fovea. The relationships of the macular gradient with age, axial length, and spherical equivalent were analyzed. RESULTS: In 8 eyes (12.5%), the bottoms of the staphylomas were in the fovea, and there was no macular gradient. However, in the other 56 eyes (87.5%), the bottoms of the staphylomas were not in the foveal area, and macular gradients existed. Staphylomas were commonly located in the infero-nasal retinal area. The mean macular gradient (tangent theta) was 0.26 +/- 0.08 at 1 mm distance from the fovea and 0.28 +/- 0.10 at 2 mm. No significant relationships were observed between macular gradient and axial length, patient age, or spherical equivalent. CONCLUSIONS: TD OCT reveals staphyloma location. If the location is outside of the fovea, a macular gradient exists and can be measured by OCT. Axial length measurement error may occur in eyes with poor visual fixation and steep macular gradients.

PURPOSE: The early surgical outcomes of endoscopic thyroidectomy in papillary thyroid cancer (PTC) are comparable to those of conventional open thyroidectomy; however, there is little evidence about long-term outcomes. The aim of this study was to compare the 5-year surgical outcomes of endoscopic versus open thyroidectomy. METHODS: We reviewed 804 patients with PTC who underwent thyroidectomy between October 2008 and October 2010. Of these, 703 patients received conventional open thyroidectomy (OT group) and 101patients underwent endoscopic thyroidectomy (ET group). The clinicopathologic characteristics and surgical outcomes were compared between those treatments. RESULTS: ET was applied significantly more often in young patients and females. The lobectomy and unilateral CCND were performed more frequently in ET, and the mean tumor size was smaller. The prevalence of extrathyroidal extension, multiplicity, and lymphatic invasion was more frequent in OT. The T and TNM stage were more advanced in OT, whereas the N status was similar between treatments. The mean surgical time was significantly longer for ET, while the number of retrieved lymph nodes was greater in OT. However, the stimulated thyroglobulin levels at first RAI ablation, total amount of RAI administration and 5-year recurrence rate did not significantly differ between groups. The incidence of transient hypocalcemia was significantly higher in OT, but the incidence of permanent hypocalcemia and transient/permanent recurrent laryngeal nerve injury were similar in both groups. CONCLUSION: Endoscopic thyroidectomy might be a safe and effective procedure in well-selected PTC patients

PURPOSE: B-cell lymphoma 2 (BCL2) is an antiapoptosis protein and an important clinical breast cancer prognostic marker. As the role of BCL2 is dependent on the estrogen receptor (ER) status, this effect might differ according to molecular subtypes. The aim of this study was to evaluate the relationship between the prognostic outcomes and BCL2 expression among the molecular subtypes. METHODS: We retrieved the data of 1,356 patients who were newly diagnosed with malignant breast cancer between November 2006 and November 2011. Immunohistochemistry was used to measure ER, progesterone receptor, human epidermal growth factor receptor 2 (HER2), Ki-67, and BCL2 expression. We classified breast cancer into five molecular subtypes based on the 13th St. Gallen International Expert Consensus, including luminal A, luminal B (HER2-negative), luminal B (HER2-positive), HER2-overexpression, and triple-negative subtypes. We analyzed the clinicopathological features and assessed the correlation between BCL2 expression and clinical outcomes, such as relapse-free survival (RFS) and disease-specific survival (DSS) according to the five molecular subtypes. RESULTS: A total of 605 cases of breast cancer (53.8%) showed BCL2 expression. BCL2-positive expression was associated with young age (<50 years, p=0.036), lower histological grade (p<0.001), low Ki-67 level (<14%, p<0.001), hormone receptor positivity (p<0.001), HER2 negativity (p<0.001), luminal breast cancer (p<0.001), and low recurrence rate (p=0.016). BCL2-positive expression was also associated with favorable 5-year RFS (p=0.008, 91.4%) and DSS (p=0.036, 95.6%) in all the patients. BCL2-positive expression in luminal A breast cancer resulted in significantly favorable 5-year RFS and DSS (p=0.023 and p=0.041, respectively). However, BCL2 expression was not associated with the prognosis in the other subtypes. CONCLUSION: The prognostic role of BCL2 expression in breast cancer is subtype-specific. BCL2 expression differs according to the molecular subtype and is a good prognostic marker for only luminal A breast cancer.

PURPOSE: The follicular variant of papillary thyroid carcinoma (FVPTC) is the most common subtype of papillary thyroid carcinoma (PTC). However, the clinicopathologic features of patients with FVPTC with those of patients with pure PTC is ill-understood. This study evaluated differences in clinicopathologic features of FVPTC compared with pure PTC. METHODS: All patients with FVPTC or pure PTC diagnosed between January 2006 and August 2008 at our institution were retrospectively reviewed. The two groups were compared in terms of clinocopathological features. RESULTS: Of 417 patients, 370 had PTC, and 47 patients had FVPTC. The meanage was 47.1 years. There was no differencein age and sex ratio between the two groups, and both groups were similar in terms of tumor size, presence of multifocality, thyroid capsular invasion, and extrathyroidal extension. However, FVPTC patients had significantly lower lymph node metastases (P=0.015) and significantly higher tumor encapsulation (P=0.031). Galectin-3 expression was decreased in FVPTC (P=.012). CONCLUSION: The clinicopathologic features of FVPTC are more favorable. The possibility of FVPTC could be considered when thyroid nodules with negative galectin-3 expression have suspicious or malignant fine needle aspiration biopsy.
