Fibrotic focus in infiltrating ductal carcinoma of the breast: A significant histopathological prognostic parameter for predicting the long-term survival of the patients
The presence of fibratic fows (FF) in infiltrating ductal carcinoma (IDC) has been shown to be an important histological factor associated with high tumor aggressiveness, or early tumor recurrence or death. Ho...

The fibrotic focus in advanced colorectal carcinoma: a hitherto unrecognized histological predictor for liver metastasis
A fibrotic focus (FF) is a clearly defined area consisting of fibroblasts and/or collagen fibres arranged in irregular or storiform patterns within tumours. We looked to see whether FF in advanced colorectal ...

Invasive carcinoma derived from intraductal papillary-mucinous carcinoma of the pancreas: clinicopathologic and immunohistochemical study of eight cases
Most intraductal papillary-mucinous carcinomas (IPMCs) of the pancreas are resectable and curable, but some develop into frankly invasive carcinomas. We studied the clinicopathologic features of eight cases o...

Proliferative activities of tumor stromal cells play important roles in tumor thickness and progression of T3 ulcerative-type colorectal cancer
The central depressed area thickness (tumor thickness) of colorectal cancers is an important prognostic parameter for colorectal cancer patients. We examined whether the proliferative activities of tumor and s...
