In this paper, we address the problem of discovering coreference relations between formulas and the surrounding text. The task is different from traditional coref-erence resolution because of the unique structure of the formulas. In this paper, we present an approach, which we call 'CDF (Concept Description Formula)', for mining coreference relations(More)
—We found a way to use mathematical search to provide better navigation for reading papers on computers. Since the superficial information of mathematical expressions is ambiguous, considering not only mathematical expressions but also the texts around them is necessary. We present how to extract a natural language description, such as variable names or(More)
BACKGROUND Alpha methylacyl-CoA racemase (AMACR) is a useful diagnostic marker for prostate adenocarcinoma. However, its usefulness has not been fully validated in Japanese patients. The aim of this study was to evaluate the diagnostic utility of AMACR in prostate needle biopsy examination in Japanese patients. METHODS A total of 119 prospective(More)
Solitary fibrous tumors (SFT) are relatively rare spindle cell neoplasms that typically arise in the pleura. Recently, extrathoracic SFT that have arisen in various anatomic sites have been recognized. The histogenesis and prognosis of SFT of the kidney are not well understood because only 11 cases have been reported. We report a case of SFT of the left(More)
(Objective) The Clinical Practice Guidelines for Prostate Cancer (2012 Edition) recommend a 10- to 12-core biopsy comprising six standard cores from the apex, midgland, and base as well as cores from six peripheral zones (PZ) outside these sites. In this study, we compared localization results (mapping) based on 12-core prostate biopsy specimens from the(More)
In patients with Fournier's gangrene, massive debridement is necessary. The debrided region is usually near the anus, which means that management of evacuation becomes difficult and a colostomy is often created for diversion of stool. Our two patients were a 72-year-old man with scrotal swelling and disturbance of consciousness and a 65-year-old man with(More)
A 59-year-old man was admitted to our hospital with a left renal mass. A tumor was removed by radical nephrectomy and histological examination revealed renal cell carcinoma (pT2 N0 V1a). Two years later, CT scan showed multiple lung metastases. Despite treatment with recombinant IFN-alpha 2b, 5-FU, and MMC, the disease showed slow progression. About three(More)
PURPOSE To compare the usefulness of the World Health Organization (WHO) 1973 classification with the WHO/International Society of Urological Pathology (ISUP) classification in pTa bladder tumors. MATERIALS AND METHODS A retrospective analysis was performed on 132 patients (107 men and 25 women; mean age 69 years) with a initial diagnosis of pTa bladder(More)
The case pertains to a 47-year-old male. He consulted our institute regarding a tumor in his right kidney. Endoscopic retroperitoneal nephrectomy of the right kidney was conducted to remove the tumor. The postoperative pathology was Renal Cell Carcinoma (Clear cell carcinoma, pT1b, pNx, V (+), Fuhrman grade 4). Multiple lung metastases were observed upon CT(More)
PURPOSE To investigate the outcomes for single institution with prostate cancer treated with radical prostatectomy (RP). MATERIALS AND METHODS A retrospective analysis was performed on 406 patients who underwent RRP from January 1991 to December 2005 for cT1-3N0M0 prostate cancer. To evaluate the change of the patient background, we divided the 15 years(More)
