Objective: To investigate the clinicopathological factors and prognostic status of young Mammary Paget's disease (MPD) patients with invasive ductal carcinoma (IDC). Methods: In this study, we defined the age at diagnosis below 40 years old as young patients, and retrospectively analyzed data from 123 MPD-IDC patients who were admitted at the Cancer Hospital Chinese Academy of Medical Sciences from June 2002 to February 2019. Patients were divided into the young group (≤40 years old, 15 cases) and the old group (>40 years old, 108 cases) according to the age of onset, and the clinicopathological characteristics and prognosis of the two groups were compared. Cox regression model analysis was used to analyze the prognosis influencing factors. Results: The proportions of patients in the young group with non-menopausal, axillary lymph node metastasis, and Ki-67 index ≥15% were 93.3% (14/15), 73.3% (11/15), and 86.7% (13/15), respectively, which were higher than those in the old group [45.4% (49/108), 39.8%(43/108), and 60.2% (65/108), respectively] , with statistically significant differences (P<0.05). At an average follow-up of 63.2 months, patients in the young group had a significantly shorter disease-free survival (DFS) compared with that of the old group (P=0.012), while the difference in overall survival (OS) between the two groups was not statistically significant (P=0.161). Multifactorial Cox regression analysis showed that axillary lymph node status was an independent influencing factor on OS (HR=3.339, 95% CI: 1.121-9.943) in patients with MPD-IDC, while age was not. Conclusion: Compared with the old group, young patients with MPD-IDC have a higher incidence of axillary lymph node metastasis, high Ki-67 expression, and a shorter DFS, but age is not an independent influencing factor on DFS or OS in patients with MPD-IDC.

PURPOSE: Absorbable retaining thread (ART) needle localization utilizes a guiding needle with a thread; this technique was invented to reduce patient discomfort and wire migration. We investigated the feasibility of ultrasound (US)-guided ART needle localization for nonpalpable breast lesions. METHODS: ART needle localization was performed for 26 nonpalpable breast lesions in 26 patients who were scheduled to undergo surgical excision the day after localization. Seventeen breast lesions were initially diagnosed as invasive ductal carcinoma, six as ductal carcinomas in situ, and one as fibrocystic change. The other two cases without an initial pathologic diagnosis had suspicious US features, and excision was planned concomitantly with contralateral breast cancer surgery. The primary outcome was the technical success rate of ART needle localization confirmed by US immediately after the procedure, and the secondary outcomes were the percentage of clear margins on pathology and the complication rate of ART needle localization. RESULTS: The technical success rate of ART needle localization was 96.2% (25 of 26 patients), and the ART was located 1 cm away from the mass in one patient (3.8%). The lesions were successfully removed with clear margins in all 26 patients. No significant complications related to ART needle localization were observed. CONCLUSION: ART needle localization can be an alternative to wire needle localization for nonpalpable breast lesions.

OBJECTIVETo explore the clinical indications of MRI-guided puncture positioning or biopsy, and evaluate the clinical practical value.

METHODSThe clinicopathological data of 30 patients who underwent MRI-guided puncture positioning or biopsy were retrospectively collected and analyzed, and the patients were followed up after operation.

RESULTSThe success rate of MRI-guided puncture was 100%. After biopsy or surgical resection, the pathological diagnoses were as follows: 6 cases (20.0%) of invasive carcinoma, 9 cases (30.0%) of ductal carcinoma in suit (DCIS), and 15 cases (50.0%) of benign lesions, and the false negative rate was 0.In the 30 patients, the lesions of 22 patients were not clear and difficult to analyze qualitatively by ultrasound or mammography imaging examination. After MRI-guided puncture positioning or biopsy, the pathological examination showed that 11 cases (50.0%) of them were malignant tumors. MRI examinations indicated as malignant in 21 cases, among them, seven cases were pathologically confirmed as benign pathology, with a false positive rate of 33.3%. MRI examination considered benign in 9 cases, in which one case was pathologically diagnosed as malignant, thus, the false negative rate was 11.1%.In the 30 patients, there were no hematoma, infection and other complications after the puncture. The median follow-up time was 7.5 months. One patient died due to breast cancer metastasis, one patient showed relapse by imaging examination and underwent surgery, one case was lost, and the remaining patients were normal in the regularly follow-up results.

CONCLUSIONSMRI-guided biopsy of breast microlesions is a safe, rapid and accurate diagnostic method. When the ultrasound and mammography can not find clear lesions or the lesions are difficult to analyze qualitatively, MRI-guided puncture positioning or biopsy can be applied to improve early diagnosis and treatment, and reduce false negative rate of breast cancer.

Cases of phenotypic heterogeneity of cells within tumors have recently been reported. Here, we report on a patient with characteristic intra-tumor double primary metastases in the lung. This patient was a 40-year-old Korean woman who had been diagnosed with breast cancer (T1N0M0, estrogen receptor/progesterone receptor/HER2 +/+/+) and papillary thyroid cancer three years prior and underwent a complete surgical resection followed by appropriate adjuvant treatment with radiation, hormone, and radioactive iodine. She was recently admitted for newly developed pulmonary nodules. Metastasectomy through video-assisted thoracoscopic surgery revealed recurrent double primary cancer with two different components (metastatic ductal carcinomas from the breast and metastatic papillary carcinomas from the thyroid gland) in each pulmonary nodule in the right upper lobe and right middle lobe. To the best of our knowledge, this is the first report of simultaneous recurrent double metastasis in one organ from different primary origins.

OBJECTIVE: To evaluate the retrieval rate and accuracy of ultrasound (US)-guided 14-G semi-automated core needle biopsy (CNB) for microcalcifications in the breast. MATERIALS AND METHODS: US-guided 14-G semi-automated CNB procedures and specimen radiography were performed for 33 cases of suspicious microcalcifications apparent on sonography. The accuracy of 14-G semi-automated CNB and radiology-pathology concordance were analyzed and the microcalcification characteristics between groups with successful and failed retrieval were compared. RESULTS: Thirty lesions were successfully retrieved and the microcalcification retrieval rate was 90.9% (30/33). Thirty lesions were successfully retrieved. Twenty five were finally diagnosed as malignant (10 invasive ductal carcinoma, 15 ductal carcinoma in situ [DCIS]) and five as benign. After surgery and mammographic follow-up, the 25 malignant lesions comprised 12 invasive ductal carcinoma and 13 DCIS. Three lesions in the failed retrieval group (one DCIS and two benign) were finally diagnosed as two DCIS and one benign after surgery. The accuracy of 14-G semi-automated CNB was 90.9% (30/33) because of two DCIS underestimates and one false-negative diagnosis. The discordance rate was significantly higher in the failed retrieval group than in the successful retrieval group (66.7% vs. 6.7%; p < 0.05). Punctate calcifications were significantly more common in the failed retrieval group than in the successful retrieval group (66.7% vs. 3.7%; p < 0.05). CONCLUSION: US-guided 14-G semi-automated CNB could be a useful procedure for suspicious microcalcifications in the breast those are apparent on sonography.

OBJECTIVETo study the clinicopathologic features, immunophenotype and differential diagnosis of cystic hypersecretory lesion (CHL) of the breast.

METHODSClinicopathologic and follow-up data of six cases of breast CHL in 2010-2013 were collected and reviewed.Immunohistochemical and mucinous staining was performed.

RESULTSAll six patients were female, age ranged from 37 to 71 years (average 49.3 years). Three cases were cystic hypersecretory hyperplasia (CHH), the other three cases were cystic hypersecretory carcinoma (CHC). Clinically the lesions presented as either breast mass or mammographic calcification.Grossly, the cystic hypersecretory lesions were poorly circumscribed, with multiple colloid containing cysts on the cut surface. Microscopically, the remarkable feature was numerous enlarged cysts which contained densely eosinophilic homogeneous secretion similar to the colloid seen in thyroid follicles, and calcification was seen in the cyst in one case. The secretion was D-PAS and mucicarmine positive. The lining epithelium of the cysts was uniformly flat, cuboid or columnar, and arranged in a monolayer. The cells may be arranged in turfs, solid or micropapillary patterns in CHH.In cases with dysplasia, the epithelium showed cytological and structural atypia, but the usual morphology of atypical dutal hyperplasia such as arcades, rigid bridges or cribriform pattern was less common. The three CHC included two invasive ductal carcinomas (IDC) and one ductal carcinoma in situ (DCIS).In CHL, there was immunoreactivity to S-100 protein, CK5/6 and CK14.Of the three CHCs, ER and PR were expressed in only one IDC.No HER2 expression was identified in the two invasive CHCs.One patient was lost to follow-up, and the rest were uneventful at 18 months.

CONCLUSIONSCHL of the breast is a rare pathological entity. Multiple colloid-filled cysts is a unique histological feature. The epithelium of CHL may show usual hyperplasia, dysplasia or carcinoma.
