[A Resectable Case of Highly Locally Advanced Cecal Cancer in an Elderly Patient after Bypass Surgery and Chemotherapy].

An 83-year-old woman underwent an examination for right lower abdominal pain and was diagnosed with highly advanced cecal cancer. CT showed no metastasis; thus, we attempted resection or bypass surgery. While no liver metastasis or peritoneal dissemination was observed intraoperatively, the circumflex region was highly infiltrated to the peritoneum and retroperitoneum.

Mixed neuroendocrine-non-neuroendocrine neoplasms of the gallbladder: a case report.

Background:  Primary neuroendocrine tumors of the gallbladder (GB-NETs) are rare, accounting for 0.5% of all NETs and 2.1% of all gallbladder cancers.

[Successful Treatment with Nab-Paclitaxel for Stage Ⅳ Gastric Cancer in an Elderly Patient on Hemodialysis].

An 84-year-old man on hemodialysis was referred to our department for an advanced gastric cancer with pyloric stenosis. Pre-operative CT showed thickening of the stomach wall at the primary lesion and regional lymph node metastasis, while no clear peritoneal metastasis was found. However, we found peritoneal disseminations during the operation, so gastrojejunal bypass was performed.

[Efficacy of Laparoscopic Gastrojejunal Bypass for Unresectable Gastric Cancer with Pyloric Stenosis].

In general, gastrojejunal bypass is performed for unresectable gastric cancers with stenosis. It enables patients to take food and be discharged from the hospital earlier. Previously, we used to primarily perform open gastrojejunal bypass; however, recently, we perform laparoscopic gastrojejunal bypass because it is minimally invasive.

[A Case of Synchronous Multiple Liver Metastases from Ascending Colon Cancer Showing Pathological Complete Response to CapeOX Treatment].

The patient was a 30-year-old man who underwent a medical examination for shortness of breath.An abdominal computed tomography(CT)scan revealed advanced ascending colon cancer with multiple metastases to the liver.We performed a laparoscopic right hemicolectomy first, due to the obstruction.

Docetaxel, cyclophosphamide, and trastuzumab as neoadjuvant chemotherapy for HER2-positive primary breast cancer.

Background: The standard primary systemic therapy for human epidermal growth factor receptor 2-positive (HER2+) breast cancer is anthracyclines and/or taxanes combined with trastuzumab, which demonstrates a high pathological complete response (pCR). A pCR is a predictive marker of prognosis. However, results slightly differ, depending on the hormone receptor status.

Docetaxel and cyclophosphamide as neoadjuvant chemotherapy in HER2-negative primary breast cancer.

Background: Docetaxel plus cyclophosphamide (TC) has recently been established as a standard adjuvant chemotherapy regimen for HER2-negative (HER2-) operable breast cancer. However, the efficacy and tolerability of TC as neoadjuvant chemotherapy (NAC) remain unclear. We, therefore, conducted a prospective study to evaluate the efficacy of TC NAC in HER2- primary breast cancer.

Giant cell arteritis of the breast: a case report with a review of literatures.

Although giant cell arteritis (GCA), clinically designated as temporal arteritis, is recognized as a systemic disease, the breast may be the primary organ in which it is manifested. GCA of the breast is a rare disease that mainly occurs in postmenoposal elderly women. It manifests as nodules or pain in the breast, with or without tenderness, and is associated with significant constitutional symptoms that resemble those of polymyalgia rheumatica (PMR).

Clinicopathological evaluation of renal allograft treated with anti-CD25 monoclonal antibody.

Twenty-seven living-donor kidney recipients were treated with the antibody against CD25 as the induction immunosuppressive agent. They did not develop acute rejection within 1 month after transplantation, and mean serum creatinine level at 1 month was 1.0 +/- 0.

Management and outcome of living kidney grafts with multiple arteries.

Purpose: Kidney allografts with multiple renal arteries (MRAs) have been used with increasing frequency since the advent of laparoscopic live donor nephrectomy. To determine if MRA grafts affect the short- and long-term outcomes of grafts and patients, we analyzed 340 grafts procured by open nephrectomy.

Methods: We divided the graft recipients into five groups according to the methods used for vascular reconstruction.

Expression of cyclooxygenase-1 and -2 in human breast cancer.

Purpose: We investigated the expression of cyclooxygenase (Cox-1 and Cox-2) in mammary tissues from patients with breast cancer.

Methods: We used reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry.

Results: The cancer cells showed very weak expression of Cox-1, but strong expression of immunoreactive Cox-2.

Tissue factor antisense oligonucleotides prevent renal ischemia-reperfusion injury.

Background: Tissue factor (TF) expression is induced on macrophages and endothelial cells during the immune response. We designed an antisense (AS) phosphorothioate oligodeoxynucleotide (ODN) to specifically inhibit the expression of rat TF to study the effects of the AS ODN on renal ischemia-reperfusion injury in the rat.

Method: AS-1 ODN for TF was delivered intravenously to inhibit the expression of TF in endothelial cells.

Clinicopathological evaluation of renal allografts of four patients by 20-year protocol biopsies.

Twenty-year protocol biopsies were performed in four cases of renal transplant recipients with grafts that had survived 20 years or more. All four recipients received transplants from their parents, and never had episodes of acute rejection. They were maintained with the conventional immunosuppressive protocol including azathioprine, mizoribine, and prednisolone.

Pulmonary embolism in a living-related kidney transplantation donor.

Living-related renal transplantation is the optimal therapy for patients with end-stage renal disease (ESRD). Normally, complications are rare in living-related donor nephrectomy. However, we experienced a case of pulmonary embolism (PE).

Antisense oligonucleotide for tissue factor inhibits hepatic ischemic reperfusion injury.

Tissue factor (TF) is an initiation factor for blood coagulation and its expression is induced on endothelial cells during inflammatory or immune responses. We designed an antisense oligodeoxynucleotide (AS-1/TF) for rat TF and studied its effect on hepatic ischemic reperfusion injury. AS-1/TF was delivered intravenously to Lewis rats.

The role of tissue factor in renal ischemic reperfusion injury of the rat.

Background: Tissue factor (TF) is a membrane-bound glycoprotein that is the primary cellular initiator of the blood clotting cascade and its expression is induced on macrophages and endothelial cells during the inflammatory or immune response. Tissue factor pathway inhibitor (TFPI) regulates the extrinsic pathway of blood coagulation through its ability to inhibit tissue factor activity. We studied the role of TF in the kidney following warm ischemic reperfusion and studied the effect of TFPI in vivo.
