Occult breast cancer, which develops as a metastatic lesion with no primary tumor detected in the breast, is a rare breast cancer. A 68-year-old female patient particularly complained of the presence of a right axillary mass. The mass in the right axilla was palpable, but no tumor was found in both the breasts on palpation, ultrasound examination, or MRI. Partial breast resection and axillary lymph node dissection were performed following a diagnosis of invasive ductal carcinoma by core needle biopsy. There was no mammary gland tissue present around the tumor due to the pathology of the disease, and the tumor was diagnosed as occult breast cancer...

We report a case of a non-invasive ductal carcinoma revealed on long-term follow-up of spontaneous nipple discharge. The patient, a 36-year-old woman, had noticed spontaneous nipple discharge from both breasts over a 3-year period. Mammography and ultrasonography did not reveal any lesions in the breasts. The nipple discharge from her left breast stopped 36 months after initial clinical assessment. However, the nipple discharges from her right breast transformed into a bloody discharge from a single duct. Ultrasonography showed a tumor, 6mm in diameter, in the upper-outer quadrant of her right breast...

BACKGROUND: Intraoperative evaluation of the axillary sentinel lymph node (SLN) in patients with breast carcinoma reduces the need of re-operations in cases where an axillary completion lymph node dissection (CLND) is indicated. Different methods have been used to determine the SLN status intraoperatively, e.g. frozen section histology (FS) and touch imprint cytology (TIC). The sensitivity of intraoperative TIC examination on SLN is not consistent between different studies and varies according to different tumor histologic subtypes, tumor size and the age of the patient...

Long noncoding RNAs (lncRNAs) or exosomes have recently been shown to play vital regulatory or communication roles in cancer biology. However, the roles and mechanisms of exosomal lncRNAs in tumor invasion or metastasis of pancreatic ductal adenocarcinoma (PDAC) remain unknown. In this study, we aimed to investigate the detailed roles and mechanisms of tumor-generated exosomes in progression and metastasis of PDAC in vitro and in vivo. We identified a lncRNA-Sox2ot from exosomes of highly invasive PDAC cells, and analyzed the expression of Sox2ot in the plasma samples and found that the plasma exosomal Sox2ot expression was high and correlated with TNM stage and overall survival rate of PDAC patients...

BACKGROUND: Preoperative staging of the axilla is important to allow decisions regarding neoadjuvant treatment and the management of the axilla. Invasive lobular carcinoma metastases are difficult to detect because of the infiltrative pattern of the nodal spread. In this study the sensitivity of preoperative axillary staging between invasive lobular (ILC) and ductal (IDC) carcinoma was compared. METHODS: All women diagnosed with pure ILC or IDC in the West of Scotland in 2012-2014 were identified from a database maintained prospectively within the Managed Clinical Network...

Patients with pancreatic ductal adenocarcinomas (PDAC) have one of the poorest survival rates of all cancers. The main reason for this is related to the unique tumor stroma and poor vascularization of PDAC. As a consequence, chemotherapeutic drugs, such as nab-paclitaxel and gemcitabine, cannot efficiently penetrate into the tumor tissue. Non-invasive radiofrequency (RF) mild hyperthermia treatment was proposed as a synergistic therapy to enhance drug uptake into the tumor by increasing tumor vascular inflow and perfusion, thus, increasing the effect of chemotherapy...

Pancreatic Ductal Adenocarcinoma (PADC) metastasis is the leading cause of morality of this severe malignant tumor. Proteases are key players in the degradation of extracellular matrix which promotes the cascade of tumor metastasis. As a kind of serine proteases, the kallikrein family performs vital function on the cancer proteolysis scene, which have been proved in diverse malignant tumors. However, the specific member of kallikrein family and its function in PDAC remain unexplored. In this study, by data mining of GEO datasets, we have identified KLK10 is upregulated gene in PDAC...

BACKGROUND: Enhanced magnetic resonance imaging (MRI) and ultrasonography (US) are used to assess residual lesions after preoperative chemotherapy before surgery. However, residual lesion assessments based on preoperative imaging often differ from postoperative pathologic diagnoses. We retrospectively reviewed the accuracy of preoperative residual lesion assessments, including ductal carcinoma in situ (DCIS) cases to find criteria for cases in which surgery can be omitted. METHODS: We reviewed 201 patients who received preoperative chemotherapy and surgery in our hospital from January 2013 to November 2016...
