Rationale, indications, techniques and applications of interstitial brachytherapy for carcinoma cervix

With evolution of different newer radiotherapy techniques, still the role of brachytherapy in different gynecological malignancies has not sublimed. Most commonly used form of brachytherapy in carcinoma cervix patients is intracavitary brachytherapy. However, all the patients do not qualify for the treatment with intracavitary brachytherapy due to certain clinicopathological conditions. This warrants use of interstitial brachytherapy technique for treatment. For getting good results from interstitial brachytherapy, a good expertise and a proper infrastructure are needed. For perineal interstitial brachytherapy, different templates have been designed, used, and published by authors in different literature over the period. Among all these different templates, Martinez Universal Perineal Interstitial Template (MUPIT) has been used in gynecological, urological, and anorectal malignancies. In this literature review, we have discussed mainly MUPIT.
