Current techniques for permanent prostate brachytherapy are associated with excellent biochemical control in patients with localized prostate cancer. Data now available confirm 5- to 10-year results with this treatment
Pediatric soft-tissue sarcomas are managed with a multimodality treatment program that includes surgery, chemotherapy, and external-beam radiotherapy (teletherapy). The use of teletherapy in young children can
Whole-breast external-beam radiation therapy (EBRT) involves a 6-week course of fractionated treatments. In
Brachytherapy boosts in combination with external-beam radiation therapy allow a highly conformal dose of radiation to be delivered to the prostate in a safe, efficient manner. Several types of brachytherapy boost
Brachytherapy is a therapeutic modality that may provide a significant improvement in the therapeutic ratio when appropriately applied, and hence, is an appealing treatment strategy for the head and neck. For several
Widespread use of prostate-specific antigen (PSA) as a screening tool has led to an increased incidence of biopsy-proven prostate cancer, as well as a shift toward more cases with clinically confined disease (stage T1 to T2). The two traditional therapeutic modalities, radical prostatectomy and external-beam radiation therapy, have undergone technical refinements. Other modalities, such as brachytherapy and cryosurgery, are also being used to treat early-stage disease. Comparisons between treatment results are difficult. Biochemical failure, based on PSA findings, is currently used to measure treatment efficacy, but the precise definition and clinical relevance of biochemical failure have yet to be established. The author presents current analyses of biochemical failure, cause-specific survival, distant metastasis, and morbidity rates following various treatment modalities. [ONCOLOGY 9(9):803-816, 1995]
Intraoperative radiation therapy (IORT) has the obvious advantage of maximally irradiating the tumor bed while eliminating surrounding normal organs from the field of radiation. This approach has been especially useful when the required radiation dose exceeds the tolerance dose of the surrounding normal tissues. However, the application of IORT has been significantly limited by cost, logistic issues, and technical problems related to delivering treatment to difficult anatomic areas. We have developed a new approach to IORT that obviates the need for patient transport: In a dedicated, shielded operating room, the surgery is performed and IORT is delivered via HDR remote afterloading. We have found this approach to be cost effective, logistically sound, and suitable for a wide range of anatomic sites. The technical aspects of the procedure, as well our preliminary results in colorectal cancer, will be presented. Lastly, the authors present the technical aspects of delivering HDR intraoperative brachytherapy, their dosimetry atlas, and their results using HDR-IORT in the treatment of patients with colorectal cancer[ONCOLOGY 9(7):679-683, 1995]
past decade has witnessed a host of technologic improvements in prostate cancer therapy. The three major modalities offered in most managed care plans include radical prostatectomy, external-beam radiation therapy (EBRT), and interstitial brachytherapy (seed implant). Continued technologic advancement has led to incremental improvements in the safety and effectiveness of each modality. However, these improvements have led to a significant increase in the cost of treatment.
Mismanaged therapy at one institution has dealt a blow to the field, but practitioners explain why the technique remains worthwhile.
Repeat lumpectomy and retreatment radiotherapy following ipsilateral breast tumor recurrence (IBTR) by either external-beam irradiation or brachytherapy in lieu of salvage mastectomy is an area of significant recent clinical interest. Multiple authors have reported their results, with encouraging numbers of patients avoiding mastectomy.[1‑4]
