Skull Base Metastasis of Breast Cancer With Oculomotor and Trochlear Nerve Palsy.

Skull base metastatic tumors are rare. Breast cancer in particular can cause bone metastases after a long period of time. A 70-year-old woman presented with multiple cranial nerve palsy.

Feasibility of Salvage Re-irradiation With Stereotactic Radiotherapy for Recurrent Glioma Using CyberKnife.

Aim: To evaluate the toxicity and efficacy of re-irradiation with salvage stereotactic radiotherapy (SRT) for recurrent glioma using CyberKnife.

Patients And Methods: This study retrospectively investigated 35 patients with 48 recurrent grade 2-4 gliomas who received SRT between 1998 and 2011. Six patients (17.

Tissue Expander Placement to Prevent the Adverse Intestinal Effects of Radiotherapy in Malignant Pelvic Tumors.

We herein report the findings of 3 patients with primary Ewing sarcoma in a pelvic lesion who underwent the placement of a tissue expander (TE) before radiation therapy to prevent the adverse effects of radiotherapy. The simulation study showed that the TE drastically reduced volume of the intestine that was irradiated at all dose levels. All patients could receive the scheduled dose of radiotherapy without any acute and late complications such as diarrhea, melena, the dislodging of the TE, infection, or the formation of fistulae.

Hypofractionated stereotactic radiation therapy in three to five fractions for vestibular schwannoma.

Objective: To retrospectively examine the outcomes of hypofractionated stereotactic radiation therapy in three to five fractions for vestibular schwannomas.

Methods: Twenty-five patients with 26 vestibular schwannomas were treated with hypofractionated stereotactic radiation therapy using a CyberKnife. The vestibular schwannomas of 5 patients were associated with type II neurofibromatosis.

Correlation between dosimetric parameters and late rectal and urinary toxicities in patients treated with high-dose-rate brachytherapy used as monotherapy for prostate cancer.

Purpose: To evaluate the correlation between dosimetric parameters and late rectal and urinary toxicities in high-dose-rate brachytherapy (HDR-BT) used as monotherapy for prostate cancer.

Methods And Materials: The data of 83 patients treated with HDR-BT alone for prostate cancer from 2001 through 2005 at Osaka University Hospital were analyzed. Median follow-up time was 36 months (range, 18-70).

High-dose-rate interstitial brachytherapy for previously untreated cervical carcinoma.

Purpose: The aim of the study was to evaluate the results of high-dose-rate interstitial brachytherapy (HDR-ISBT) for patients with advanced cervical carcinoma in which intracavitary radiation therapy may result in a suboptimal dose distribution.

Methods And Materials: Between 1995 and 2005, 25 patients of median age 64 years were treated with external beam radiation therapy and HDR-ISBT. The International Federation of Gynecology and Obstetrics stages of the patients were I (4%), II (16%), III (68%), and IVA (12%).

Interaction between sulfonephthalein dyes and chitosan in aqueous solution and its application to the determination of surfactants.

A spectrophotometric method for the determination of ionic surfactants with Bromophenol Blue (BPB) based on incorporation into a precipitated chitosan was studied. Cationic surfactants (CS+), such as a quaternary ammonium ion containing a long-chain alkyl group, associate with BPB2- buffered at about pH 9 to form the ion associate (CS+)2 x BPB2-. CS+ associates with anionic surfactants (AS-).
