PURPOSE The standard treatment for primary localized gastric gastrointestinal stromal tumor (GIST) is surgical resection. The clinical behavior of gastric GIST after surgical resection is extremely variable. We conducted a multicenter, retrospective study of gastric GISTs patients who underwent curative surgical resection to evaluate clinical features and the prognosis of surgically treated gas...

We herein report two patients with endometriosis in the cecum. Both presented a protruding, subepithelial tumor on colonoscopy and were diagnosed cecal after surgical resection. It is notable that lesions not initially identified computed tomography (CT), while CT colonography air/carbon dioxide insufflation resulted detection of tumor. These cases highlight possibility false-negative results c...

We have routinely used an intraoperative CT (i-CT) system in over 800 neurosurgical procedures since 1997. To investigate the utility of i-CT in low-grade glioma (LGG) surgery, we investigated whether i-CT improved the extent of tumor resection and prognosis in 46 patients with histologically confirmed LGG consisting of 27 patients with World Health Organization grade II astrocytoma, 12 with ol...

HYPOTHESIS Bowel resection followed by chemotherapy is a better management strategy than immediate chemotherapy in asymptomatic patients with colorectal cancer and unresectable liver-only metastases at presentation. DESIGN Retrospective study. SETTING University hospital. PATIENTS Sixty-five consecutive symptom-free colorectal cancer patients with unresectable synchronous metastases confi...

A 6-year-old boy with ganglioneuroblastoma, received 4 courses of chemotherapy and underwent partial resection the tumor. The control scintigraphy 123 I-metaiodobenzylguanidine ( I-mIBG) was performed, including single photon emission computed tomography protocol combined (SPECT/CT), revealing residual tumor pathological uptake I-MIBG. In addition to this, there a focal I-mIBG in gallbladder. t...

How are spinopelvic tumor resections classified? The type of pelvic resection depends on the area involved and the extent of the tumor. Problems arise when the tumor involves the sacrum and the lower lumbar spine. To obtain acceptable surgical margins in these cases, skeletal resection should extend beyond the standard hemipelvectomy (ie, the sacroiliac joint) and may include the ilium, part of...

Surgical treatment of primary brain tumors remains a considerable challenge for the neurosurgeon. Nonetheless, surgery is the mainstay of glioma therapy because it provides the means of obtaining absolute tissue diagnosis, mapping tumor margins, mechanical cytoreduction, and guidance of adjuvant therapy such as brachytherapy, gene therapy, or radiosurgery. Recent developments in computation tec...

We report a rare case of dyspnea caused by a cardiac tumor in a 53-year-old woman. The patient had undergone a cardiac tumor (inflammatory myofibroblastic tumor, 6.2 × 4.2 × 3.3 cm) resection at our institute 13 months earlier. We performed preoperative evaluations which revealed a cardiac tumor originating from the posterior wall of the left atrium. Cardiac autotransplantation surgery (cardiac...

ganglioneuromas presented as a retroperitoneal tumor around the vital organs is a rare entity. a case with unusual presentation is reported. young woman of 44 years old presented without any complaint ,that known during incidental abdominopelvic ultrasonography. it was treated with partial resection for debulking surgery. debulking surgery with preservation of organ functions is feasible in the...
