We describe 2 unusual cases of vaginal dehiscence after intracavitary brachytherapy performed following robotic laparoscopic hysterectomy (RLH) along with their management. This unusual complication, which may be more common because of the robotic procedures, can be prevented by careful examination and possible delay of the onset of brachytherapy, if indicated. Our report reviews techniques of ...

Radiotherapy procedures fall into two main categories: external beam radiotherapy and brachytherapy. In external beam radiotherapy the radiation source is at a certain distance from the patient and the target within the patient is irradiated with an external radiation beam. In brachytherapy (see Chapter 13) radiation sources are placed directly into the target volume (intracavitary or interstit...

purpose: to review on outcomes of phosphorus-32 ( 32 p) intracavitary irradiation for craniopharyngiomas. methods: a literature review of all full publications in english biomedical journals (1981-2014) was performed. the search strategy included a combination of key words “phosphorus-32”, “craniopharyngioma”, “intracystic treatment”, “brain”, “cyst”, “tumor”, “brachytherapy”, “intracavitary ir...

PURPOSE This study assessed the modeled probability of tumor control and organ at risk toxicities in locally advanced cervical cancer in patients treated by external beam radiation plus brachytherapy using intracavitary combined with interstitial brachytherapy (IC/IS) vs. intracavitary brachytherapy (IC) alone. MATERIAL AND METHODS Twenty cervical cancer patients with a mean HR-CTV volume of ...

Introduction Dosimetric accuracy is a major issue in the quality assurance (QA) program for treatment planning systems (TPS). An important contribution to this process has been a proper dosimetry method to guarantee the accuracy of delivered dose to the tumor. In brachytherapy (BT) of gynecological (Gyn) cancer it is usual to insert a combination of tandem and ovoid applicators with a complicat...

Background: External beam radiotherapy and brachytherapy plays a vital role in the management of cancer cervix.  High dose rate brachytherapy is being presently used worldwide for the brachytherapy applications. At present, 2-Dimensional linear array detectors   are the most common QA tool used for pretreatment patient specific quality assurance in external beam radiotherapy alon...

Results: The median age was 49 years, all were male, four patients had World Health Organization Class III histology, and one with nasopharyx cancer type I. Two, 1 and 2 patients had recurrent Stage I, II, III, respectively. Median time to reirradiation was 49 months. Four patients received combined-modality treatment, consisting of external beam radiotherapy (EBRT) with chemotherapy followed b...

Standard radiation therapy for cervical cancer consists of external beam radiation therapy followed by an intracavitary brachytherapy boost. When brachytherapy cannot be performed due to unfavorable anatomy or coexisting medical conditions, stereotactic body radiotherapy with the CyberKnife is another treatment option which is less invasive and can be performed in a shorter treatment time. We p...

PURPOSE To evaluate the cumulative dose at point A for three and four centimeters central shielding. MATERIAL AND METHODS The plans of external beam radiotherapy plus conventional intracavitary brachytherapy were performed. Three or four centimeters central shieldings (after 44 Gy) were applied to the standard whole pelvis irradiation. Additional intracavitary brachytherapy 4 × 7 Gy at point ...

PURPOSE To determine the feasibility and safety of outpatient combined intracavitary and interstitial brachytherapy for cervix cancer with sedation and local anesthesia. MATERIAL AND METHODS We included patients diagnosed with non-metastatic cervix cancer and have completed brachytherapy between December 2015 and December 2016. Moderate to deep sedation was achieved using intravenous midazola...
