Interstitial brachytherapy and hyperthermia for malignant gliomas
Journal of Neuro-Oncology, 1993Interstitial brachytherapy has well-known radiobiological and radiophysical advantages that has made delivery of high doses of radiation to malignant brain tumors a possibility [1]. Over the past 10 years a great deal of clinical information attesting to the usefulness of brachytherapy in the treatment of malignant gliomas has been accrued.

Concept of dose nonuniformity in interstitial brachytherapy
International Journal of Radiation Oncology*Biology*Physics, 1993Evaluation of the 3-dimensional dose distributions of interstitial implants using the dose uniformity ratio.Single source, two sources, three and four sources arranged both linearly and in the form of a triangle or a square, ribbons with different seed spacings, a single-plane and double-plane implants were evaluated.

Interstitial Brachytherapy for Skull Base Tumors
Neurosurgery Clinics of North America, 20001. Irrespective of the histology, all tumors responded to 125I permanent BT. 2. There were no intra- or postprocedural complications, making this modality extremely safe. 3. There were no acute or late complications attributable to continuous LDR radiation with 125I permanent BT. 4.

Interstitial brachytherapy for malignant brain tumors
Seminars in Surgical Oncology, 1998For nearly 20 years, interstitial brachytherapy has been used as adjuvant treatment for malignant brain tumors in both prospective clinical trials and as part of standard therapy. Numerous publications analyzing the results of this treatment seem to indicate an improvement in median survival for highly selected patients.

Interstitial brachytherapy procedures for brain tumors
Seminars in Surgical Oncology, 1997Promising results have been obtained using brachytherapy in the treatment of brain tumors. Very low-dose rate brachytherapy (60-100 Gy given at 0.05-0.10 Gy/h) has been used for low-grade gliomas, resulting in 5- and 10-year survival probabilities of 85% and 83% for pilocytic astrocytomas and 61% and 51% for grade II astrocytomas. Only 2.6% of patients

The history of interstitial brachytherapy of prostatic cancer
Seminars in Surgical Oncology, 1997The history of interstitial brachytherapy of the prostate began in 1917 when Barringer inserted radium needles transperineally into the prostate, guided by a finger in the rectum. In 1952, Flocks et al. injected radioactive gold solution in prostatic cancer during open operation. In 1972, Whitmore et al.

Interstitial Implant Brachytherapy in Small Animals
Veterinary Clinics of North America: Small Animal Practice, 1997This article presents highlights of the physics, implantation technique, and clinical application of iridium-192 interstitial implant brachytherapy. Some of the physical differences between iridium-192 brachytherapy and cobalt-60 teletherapy are compared.

[Update on interstitial brachytherapy].
Der Radiologe, 2012Minimally invasive treatment procedures, such as image-guided local tumour ablation have gained increasing relevance in oncologic concepts. Limitations of thermal ablation procedures have led to the development of percutaneous, computed tomography (CT) guided brachytherapy.Thermal ablation procedures, such as radiofrequency ablation (RFA) and laser ...

Interstitial hyperthermia in combination with brachytherapy.
Radiology, 1983Flexible coaxial cables were modified to serve as microwave antennas operating at a frequency of 915 MHz. These antennas were inserted into nylon afterloading tubes that had been implanted in tumors using conventional interstitial implantation techniques for iridium-192 seed brachytherapy.
