Management of granulomatous mastitis: a series of 13 patients who were evaluated for treatment without corticosteroids.

Granulomatous mastitis (GM) is a rare chronic inflammatory breast condition with unknown etiology. There is still no generally accepted optimal treatment for GM. Corticosteroid treatment and/or wide excision is most commonly reported in the literature.

Comparison of gastric cancer surgery between patients aged >80 years and <79 years: complications and multivariate analysis of prognostic factors.

Background/aims: To evaluate the clinicopathological features and results of surgery for gastric cancer in elderly patients aged ˃80 years relative to those aged ˂79 years, and to recommend the appropriate surgical treatment for elderly patients.

Methodology: A total of 332 patients with gastric cancer who underwent gastrectomy in our department between 2002 and 2012 were evaluated. Of these, 81 were aged ˃80 years (Group A) and 251 were aged ˂79 years (Group B).

O-methylguanine-DNA methyltransferase as a prognostic and predictive marker for basal-like breast cancer treated with cyclophosphamide-based chemotherapy.

The O-methylguanine-DNA methyltransferase (MGMT) protein protects cells from alkylating agents by removing alkyl groups from the O-position of guanine. However, its effect on DNA damage induced by cyclophosphamide (CPM) is unclear. The present study investigated whether MGMT expression was correlated with prognosis in patients with breast cancer that was managed according to a common therapeutic protocol or treated with CPM-based chemotherapy.

[Four cases of double bypass surgery involving choledochojejunostomy and gastrojejunostomy for inoperable peripancreatic head cancer].

Peripancreatic head cancer often causes obstructive jaundice and duodenal obstruction, which reduces the quality of life and hinders the administration of anti-cancer drugs. Here, we report 4 cases of double bypass surgery( biliary and gastric) for the treatment of inoperable peripancreatic head cancer. The patients' ages ranged from 64 to 72 years.

[Palliative surgery for malignant bowel obstruction in patients with advanced and recurrent gastroenterological cancer].

We report the outcomes of palliative surgery for the treatment of malignant bowel obstruction in patients with advanced gastroenterological cancer. We studied 20 patients who had undergone palliative surgery over 3 years. We analyzed the clinical findings, surgical procedure, postoperative clinical course, and prognosis.

[Preoperative chemoradiotherapy with S-1 for advanced low rectal cancer].

We reviewed the patients with neoadjuvant chemoradiotherapy (CRT) with S-1 to evaluate the feasibility and effectiveness for locally advanced lower rectal cancer. The CRT regimen consisted of pelvic irradiation (45 Gy in fractions of 1.8 Gy), five days a week.
