Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place app...

PURPOSE To report the treatment effect of interstitial brachytherapy for abdominal wall metastases of ovarian cancer. MATERIAL AND METHODS The patient is a 44-year-old female with a diagnosis of stage IA ovarian cancer. After surgery and two cycles of chemotherapy with paclitaxel and carboplatin, the patient noticed dull pain in the lower abdomen and found a mass located in the subcutaneous t...

Pulsed-dose-rate (PDR) brachytherapy is a recent brachytherapy modality combining the radiobiological advantages of low-dose-rate (LDR) brachytherapy with increased possibilities of dose optimization and radiation safety. However, treatment duration remains protracted, as the prescribed dose is typically delivered through pulses that do not exceed 0.5 Gy/h for critical organs. It is frequently ...

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 result in significant long-term toxicities (especially growth retardation of bones and organs). Brachytherapy, if feasible, is an attractive alternative for the treatment of pediatric sof...

Objective: In locally advanced cervical cancer, the management consists of external beam radiotherapy and brachytherapy. The impact of intracavitary brachytherapy versus interstitial brachytherapy on local tumor control, survival and complications were prospectively investigated in this study. Methods: A total of 60 patients with stage IIB, IIIB cervical cancer were treated using a combination ...

The biological rationale for the use of brachytherapy, which is undergoing a significant resurgence in the United States, is reviewed with emphasis on low dose rate (LDR brachytherapy). Some of the newer alternatives that have recently been developed, such as pulsed dose rate (PDR) brachytherapy, are discussed.
