Incidental detection of pancreatic cancer by F-18-fluorodeoxyglucose positron emission tomography/computed tomography in a patient with hereditary breast and ovarian cancer syndrome.

Patients with hereditary breast and ovarian cancer syndrome (HBOC) are associated with an increased risk of developing pancreatic cancer (PC) than the general population. There is no consensus about the clinical value of F-18-fluorodeoxyglucose (FDG)-positron emission tomography/computed tomography (PET/CT) in patients with HBOC. We report a patient with HBOC in whom PC was detected incidentally by PET/CT.

HER2-positive breast cancer in a germline gene large deletion carrier.

A majority of breast cancer (BC) molecular subtype in variants carriers is triple-negative type. In contrast, human epidermal growth factor 2 (HER2)-positive BC among carriers of variants is rarely reported. A 42-year-old woman who previously received adjuvant endocrine therapy against left BC developed a left BC relapse and a right new primary BC.

Mucosa-associated lymphoid tissue (MALT) lymphoma developing in ectopic mediastinal thyroid tissue: a case report.

Background: Normally located in the neck, ectopic mediastinal thyroid tissue consists of very rare ectopic thyroid tissue that does not connect to the thyroid gland. A patient with mucosa-associated lymphoid tissue (MALT) lymphoma that has developed in mediastinal thyroid tissue, to our best knowledge, has not been previously reported.

Case Presentation: A 67-year-old woman presented with a superior mediastinal mass that was revealed by chest computed tomography (CT), an optional examination she hoped, during a medical checkup.

Elective treatment of middle colic artery aneurysm.

Middle colic artery aneurysms are rare and most have been reported with rupture or symptom. We report the successful elective treatment of a middle colic artery aneurysm without symptom, which is very rare. It failed to perform transcatheter arterial embolization for anatomical reasons, and, thus, the patient, a 77-year-old man, underwent surgical resection in spite of a history of laparotomy.

Thyroidectomy in a patient with thyroid storm: report of a case.

Thyroid storm is a life-threatening condition that is generally considered to be a contradiction to surgical intervention. We herein describe the case of a 37-year-old patient with a history of Graves' disease who was transferred to Tottori University Hospital with thyroid storm. She had been followed by her family doctor since 2006, but she had stopped taking her medication of her own volition in 2010.

Effect of chemotherapy for luminal a breast cancer.

Background: The addition of chemotherapy to endocrine therapy for luminal A breast cancer generally provides little benefit. However, the least benefit of chemotherapy in all patients with luminal A breast cancer is controversial.

Methods: This was a retrospective study of 140 patients with luminal A breast cancer who underwent surgery at Tottori University Hospital between 2001 and 2010.

ACTH-Producing Breast Cancer: A Patient Report.

Ectopic ACTH secretion in the setting of breast cancer is extremely rare but when present affects both the tumor's behavior and the incidence of complications. The patient, a 58-year-old woman, first presented with a mass in her left breast as well as multiple osseous metastases and a right femur fracture. Laboratory data revealed a hypokalemic alkalosis.

Pheochromocytoma multisystem crisis successfully treated by emergency surgery: report of a case.

Pheochromocytomas are rare neuroendocrine tumors that produce symptoms through the excess release of catecholamines. The treatment of choice is a complete surgical removal after pretreatment with an α-blocker, to prevent dangerous hemodynamic fluctuations. Newell and colleagues defined the rare, fatal condition of catecholamine crisis, which includes multiple organ failure (MOF), severe blood pressure variability, high fever, and encephalopathy, as pheochromocytoma multisystem crisis (PMC).

[A case of aggressive primary squamous cell carcinoma of the breast refractory to preoperative neoadjuvant chemotherapy].

A 42-year-old woman came to our hospital complaining of an enlarging tumor in her right breast. A core needle biopsy of the involved area demonstrated primary squamous cell carcinoma (SCC) of the breast. Preoperative neoadjuvant chemotherapies included 5-fluorouracil: 5-FU+epirubicin: EPI+cyclophosphamide: CPA (FEC), paclitaxel (PTX), vinorelbine (VNR) and 5-FU+nedaplatin (254-S) given in the order listed, but the mass continued to enlarge.

Large-cell carcinoma of the lung with a remarkable preoperative elevation of serum carcinoembryonic antigen level.

Carcinoembryonic antigen, a serum tumor marker, is useful for diagnosing cancer and for following the response to therapy in cancer cases. Serum carcinoembryonic antigen levels are also important as a predictive tool in evaluating prognosis. A 56-year-old man presented with an abnormal shadow on a chest X-ray.

Needle track dissemination of follicular thyroid carcinoma following fine-needle aspiration biopsy: report of a case.

Few reports have been concerned with the risk of needle track dissemination of tumor cells following fine-needle aspiration biopsy, especially for follicular thyroid nodules. A 61-year-old woman who underwent fine-needle aspiration biopsy and surgery 5 years previously for follicular thyroid adenoma presented with nodules that had developed in the sternocleidomastoid and omohyoid muscles of the anterior neck. These nodules were located along a line from the skin to the thyroid that coincided with the needle track of the previous biopsy.

Identification of secernin 1 as a novel immunotherapy target for gastric cancer using the expression profiles of cDNA microarray.

Despite the discovery of multiple TAAs, only a limited number is available for clinical application, particularly against epithelial malignancies. In this study we searched for novel TAAs using expression profiles of gastric cancer examined with cDNA microarray, and identified the SCRN1 gene as a candidate. SCRN1 was confirmed to be expressed in five out of seven gastric cancers with semiquantitative RT-PCR.

Identification of immunoglobulin superfamily 11 (IGSF11) as a novel target for cancer immunotherapy of gastrointestinal and hepatocellular carcinomas.

We previously performed gene expression profile analyses of 20 intestinal-type gastric cancers, and identified a set of genes whose expression levels were elevated in cancer tissues compared to their corresponding non-cancerous tissues. In the present study we focused on the immunoglobulin superfamily 11 gene (IGSF11). Its expression was also elevated in colorectal cancers and hepatocellular carcinomas as well as intestinal-type gastric cancers.

Ring finger protein 43 as a new target for cancer immunotherapy.

We have performed genome-wide exploration by using cDNA microarray profiling, and successfully identified a new tumor-associated antigen (TAA) that can induce potent cytotoxic T lymphocytes (CTLs) specific to tumor cells. In our preceding study, we identified multiple new genes by using gene expression profiling with a genome-wide cDNA microarray containing 23,040 genes. Among them, we selected RNF43 (ring finger protein 43) as a promising candidate for a TAA expressed by colon cancer cells.
