Endometriosis presenting as a perianal abscess: case report.

Endometriosis is common benign disorder characterized by the presence of endometrial glands and stroma outside the uterine cavity. Endometriosis of perianal region is a rare condition. We report a case of perianal endometriosis presenting initially as a perianal abscess.

Prediction of Response to Stereotactic Radiosurgery for Brain Metastases Using Convolutional Neural Networks.

Background: It is unclear whether radiomic phenotypes of brain metastases (BM) are related to radiation therapy prognosis. This study assessed whether a convolutional neural network (CNN)-based radiomics model which learned computer tomography (CT) image features with minimal preprocessing, could predict early response of BM to radiosurgery.

Materials And Methods: Tumor images of 110 BM post stereotactic-radiosurgery (SRS) (within 3 months) were assessed (Response Evaluation Criteria in Solid Tumor, version 1.

Prognostic factors of non-functioning pancreatic neuroendocrine tumor revisited: The value of WHO 2010 classification.

Backgrounds/aims: Various factors have been reported as prognostic factors of non-functional pancreatic neuroendocrine tumors (NF-pNETs). There remains some controversy as to the factors which might actually serve to successfully prognosticate future manifestation and diagnosis of NF-pNETs. As well, consensus regarding management strategy has never been achieved.

Surgical Strategy for T2 Gallbladder Cancer According to Tumor Location.

Background: Radical cholecystectomy is recommended for T2 gallbladder cancer. However, it is unclear whether hepatic resection is essential for peritoneal-side gallbladder cancer.

Methods: From January 2000 to December 2011, we identified T2 gallbladder cancer patients who had undergone curative intent surgery.

Clinical outcomes after percutaneous vertebroplasty for pathologic compression fractures in osteolytic metastatic spinal disease.

Objective: Percutaneous vertebroplasty (VP) can provide immediate stabilization in pathologic fractures of spinal tumors. However, long term follow-up data in cases of pathologic fractures are lacking. The authors report follow-up results of VP in 185 pathologic fractures of 102 spinal tumor patients.

Radiosurgery for recurrent brain metastases after whole-brain radiotherapy : factors affecting radiation-induced neurological dysfunction.

Objective: We retrospectively analyzed survival, local control rate, and incidence of radiation toxicities after radiosurgery for recurrent metastatic brain lesions whose initial metastases were treated with whole-brain radiotherapy. Various radiotherapeutical indices were examined to suggest predictors of radiation-related neurological dysfunction.

Methods: In 46 patients, total 100 of recurrent metastases (mean 2.

Hypofractionated stereotactic radiation therapy for skull base and upper cervical chordoma and chondrosarcoma: preliminary results.

Introduction: Chordoma and chondrosarcoma are rare tumors of the base of the skull and are difficult candidates for surgical treatment. They are also usually resistant to conventional radiation therapy. We report preliminary results of hypofractionated stereotactic radiation therapy (SRT) using the Cyberknife system (Accuray Inc.

ACNU-cisplatin continuous infusion chemotherapy as salvage therapy for recurrent glioblastomas: phase II study.

Purpose: To evaluate the activity and the toxicity of ACNU (1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-3-(2-cholroethyl)-3-nitrosourea hydrochloride) administered with cisplatin by intravenous infusion for 72 h in select patients with recurrent glioblastoma.

Patients And Methods: From April 1996 to 2002, 37 patients with histologically proven glioblastoma, who showed recurrence on image study after operation and radiation, met the eligibility criteria of our cohort. The mean time to recurrence was 9.
