Breast cancer local recurrence after mastectomy with immediate latissimus dorsi myocutaneous flap reconstruction: A case report.

Even though most local recurrences after autologous breast reconstruction occur in superficial tissue, they also occur in deep tissue in the reconstructed breast. A 49-year-old woman presented with a bloody discharge from the right nipple. Ultrasonography revealed a hypoechoic area in her right breast, which was diagnosed as ductal carcinoma in situ on histopathology.

Analysis method for PCBs in reclaimed oil using a fast-GC triple stage quadrupole mass spectrometer with the 13-component quantitation method.

It is necessary for companies supplying reclaimed oil to analyze polychlorinated biphenyls (PCBs), because there is a possibility of the presence of contaminants due to trace-level PCBs in the reclaimed oil. However, common analysis methods of PCBs are time-consuming and complicated. Fast-GC triple stage quadrupole mass spectrometer with the 13-component quantitation method is an official method for analyzing PCBs in insulating oil in Japan.

One-step nucleic acid amplification assay for intraoperative prediction of advanced axillary lymph node metastases in breast cancer patients with sentinel lymph node metastasis.

The one-step nucleic acid amplification (OSNA) assay is used to semiquantitatively measure the cytokeratin (CK)19 mRNA copy numbers of each sentinel lymph node (SLN) in breast cancer patients. The aim of the present study was to evaluate whether the diagnosis of ≥4 LN metastases is possible using the OSNA assay intraoperatively. Between May, 2010 and December, 2014, a total of 134 patients who underwent axillary lymph node dissection (ALND) of positive SLNs were analyzed.

[Two cases of human epidermal growth factor receptor 2-positive advanced gastric cancer successfully treated with S-1, cisplatin, and trastuzumab combination therapy followed by curative resection].

We report 2 cases of human epidermal growth factor receptor 2 (HER2)-positive advanced gastric cancer successfully treated with a combination therapy of S-1, cisplatin( CDDP), and trastuzumab followed by curative resection. Case 1 involved a 62-year-old man with type 3 HER2-positive gastric cancer spanning the antrum of the stomach to the duodenal bulb and directly invading the pancreatic head( cT4b[ Panc] N3H0P0M0, Stage IIIC). We diagnosed it as an unresectable cancer, and selected S-1, CDDP, and trastuzumab for combination chemotherapy.

[A case of partial pancreatectomy for recurrent metastatic renal cell carcinoma in the remnant pancreas after subtotal stomach-preserving pancreaticoduodenectomy].

We report a case in which recurrent pancreatic metastasis of renal cell carcinoma( RCC) in the remnant pancreas was resected 6 years after subtotal stomach-preserving pancreaticoduodenectomy (SSPPD). A 74-year-old man underwent right nephrectomy for RCC in 1991, left partial nephrectomy for left renal RCC metastasis in 1996, and SSPPD for pancreatic RCC metastasis in 2007. In November 2012, he was referred to our hospital with a tumor in the remnant pancreas, as seen on abdominal computed tomography (CT).
