To investigate the significance of immunohistochemical molecular subtyping, we evaluated outcomes of subtypes based on estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki-67. Using tissue microarrays, 1006 breast cancer patients between November 1999 and August 2005 were categorized into four subtypes:(More)
Ezrin, a cytoskeleton linker protein, has been reported to be involved in the metastasis of solid tumors in animal models and patients in small clinical studies. We analyzed the relationship between immunohistochemical expression of ezrin and the prognosis of osteosarcoma. We retrospectively identified 64 patients with Stage IIB osteosarcomas between 1995(More)
UNLABELLED Response to neoadjuvant chemotherapy is a significant prognostic factor for osteosarcoma; however, this information can be determined only after surgical resection. If we could predict histologic response before surgery, it might be helpful for the planning of surgeries and tailoring of treatment. We evaluated the usefulness of (18)F-FDG PET for(More)
Intercalary resection and reconstruction for tumors have become increasingly popular. We asked whether pasteurized autologous bone graft was comparable to other reported reconstruction methods regarding union rates, complications, and functional outcomes. We retrospectively analyzed the outcome of 21 intercalary pasteurized bones in lower extremities.(More)
The aim of this study was to investigate whether stereotactic body radiotherapy (SBRT) can salvage gastric cancer patients with para-aortic lymph node (PALN) recurrence. From January 2003 to December 2006, 7 patients were treated for isolated PALN recurrence from gastric cancer after curative resection. Follow up durations ranged from 19 to 33 months(More)
This study was designed to investigate the mammography and ultrasound findings of triple-negative breast cancer and to compare the results with characteristics of ER-positive/PR-negative/HER2-negative breast cancer and ER-negative/PR-negative/HER2-positive breast cancer. From January 2007 to October 2008, mammography and ultrasound findings of 245 patients(More)
BACKGROUND We examined the survivorship and functional outcome of the pasteurized autograft-prosthesis composite for distal femoral osteosarcoma. We also evaluated complications including nonunion, loosening, bony resorption, infection, and fracture. METHODS We retrospectively reviewed 15 distal femoral osteosarcoma patients who underwent reconstructions(More)
BACKGROUND With the development of preoperative adjuvant treatment, imaging techniques, and improvement of surgical technique, limb salvage is now possible even in patients with pelvic tumors. However, reconstruction after periacetabular resection is complicated and challenging. METHODS We retrospectively evaluated the usefulness of pasteurized(More)
We assessed whether new parameter that considers both tumor volume change and necrosis rate predicts metastasis-free survival of localized osteosarcoma patients. We also evaluated relationship between tumor volume change and necrosis rate or metastasis-free survival. We retrospectively reviewed 151 patients with stage II osteosarcoma who were treated with(More)
Rapamycin and its analogues are currently being tested in clinical trials as novel–targeted anticancer agents. Pre-clinical studies that used breast cancer cell lines have suggested that p-Akt or p-S6K1 expressing tumors, as well as PTEN negative tumors, were sensitive to rapamycin. The aims of this study were to determine the proportion of breast cancer(More)
