PURPOSE To report on our experience in the treatment of nasopharyngeal carcinoma (NPC) by radical radiotherapy alone in our institution during the last decade. METHODS AND MATERIALS From January 1990 to May 1999, 905 NPC patients were treated and were studied retrospectively. Radical radiotherapy was given to this cohort by conventional technique in a routine dose of 70-72 Gy to the primary t...

External beam radiotherapy can be used to treat cutaneous squamous cell carcinomas (SCC). Acute skin toxicity is the most common adverse event. In this case study we report on an elderly patient with nasal root cutaneous SCC treated with stereotactic technique using a dedicated linear accelerator (CyberKnife system). Grade 3 skin toxicity was observed but it was resolved after 6 weeks. The use ...

Radiotherapy is an integral component of management of high-grade soft tissue sarcomas. Interstitial brachytherapy is used to deliver a boost or radical dose with several advantages over external beam radiotherapy. There has always been a concern to use brachytherapy with flap reconstruction of skin defects after wide excision. We preset our initial experience with interstitial brachytherapy in...

background : this study determines the efficacy and tolerability of hypofraction- ated three-dimensional conformal radiotherapy in conjunction with daily temozolomide in treatment of previously irradiated recurrent malignant glioma. methods :we enrolled 21 patients diagnosed with recurrent or progressive malignant glioma who previously underwent external beam irradiation. all patients had hypof...

Introduction: Esophageal cancer is one of the most frequently occurring cancers in Iran and having a  high  incidence  rate  among  other  countries.  Radiotherapy  is  one  of  the  three  methods  (surgery,  radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. In this method  of treatment, the organs such as heart and spinal cord are regarded as organs at r...

We describe the construction of a custom-made bite block to be used during external beam radiotherapy to the oral cavity. The bite block is made with standard maxillofacial prosthetic techniques and materials. The design allows accurate and reproducible positioning of the perioral tissues to aid planning of radiotherapy and treatment. The compressibility of this device improves comfort for the ...

Adjuvant radiotherapy is recommended post breast conserving surgery. Accelerated Partial Breast Irradiation (APBI) offers a more attractive shorter course of treatment over 5 days compared to standard conventional external beam radiotherapy, which is often protracted. Multi-catheter interstitial APBI offers excellent dosimetric coverage. This article describes two insertion techniques for multi...
