Lip and buccal mucosa cancers can be managed with surgery, but at the high cost of impaired functional or cosmetic outcomes in some cases. Radiation therapy can be a good alternative.
This chapter describes the general principles of head and neck brachytherapy with special emphasis on clinical indications,. Endometrial cancer presents in most women at an early stage confined to the uterus and initial treatment is by hysterectomy.
Postoperative treatment is indicated for intermediate and high risk patients defined by age, stage, grade and the presence or absence of lymphovascular space invasion. Brachytherapy is one of the most efficient methods in overcoming difficulties in breathing that is caused by endobronchial obstruction in palliative treatment of bronchus cancer.
Depending on the location of the lesion in some cases brachytherapy is the treatment of choice often combined with a recanalisation procedure. Because of uncontrolled local or recurrent disease, patients may have significant symptoms such as: cough, dyspnea, hemoptysis, obstructive pneumonia or atelectasis.
Efforts to relieve this obstructive process are worthwhile, because patients may experience improved quality of their life. Biliary tract cancer is a rare disease. Surgical resection offers the best chance for long-term survival, but the results are not satisfactory and local relapses are frequent.
However, the lack of appropriate prospective trials, as well as the small size of the published series and their retrospective nature, has produced insufficient evidence for the best treatment for these patients . Non-melanoma skin cancer can be treated with brachytherapy as an alternative to surgery, with some advantages in dosimetry compared with external beam radiation due to the rapid fall-off of the dose.
Brachytherapy is now established as an effective treatment for prostate cancer alongside radical prostatectomy and external beam radiotherapy. Panagiotis Papagiannis , Jack Venselaar. This chapter aims to summarize technical and procedural information to aid the process of optimization of protection in brachytherapy,. Brachytherapy BT differs from external beam therapy EBRT in two main ways: the distribution of the absorbed dose and the time-dose patterns.

The main advantage of MRI as an imaging modality is its superior soft tissue depiction quality. To exploit the full potential of MRI for the better ability of the radiation oncologist to make the appropriate choice for the BT application technique and to accurately define the target volumes and the organs at risk, certain MR imaging criteria have to be fulfilled. Technical requirements, patient preparation, as well as image acquisition protocols have to be tailored to the needs of 3D image-based BT. Methods and parameters have been developed and progressively validated from clinical experience from different institutions IGR, Universities of Vienna, Leuven, Aarhus and Ljubljana and successfully applied during expert meetings, contouring workshops, as well as within clinical and interobserver studies. Both low and high-field imagers, as well as both open and close magnet configurations conform to the requirements of 3D image-based cervical cancer BT. Multiplanar transversal, sagittal, coronal and oblique image orientation T2-weighted images obtained with pelvic surface coils are considered as the golden standard for visualisation of the tumour and the critical organs.
