Interventional Radiology In Oncology
Price On RequestThis exciting technique has been introduced over the last decade, which initially started for HCC and now has progressed to other hepatic lesions, such as colorectal metastasis, neuroendocrine metastasis, breast metastasis, etc.Here a beta radiating agent Yttrium 90, is coated with microspheres and is injected transarterially, superselectively into the tumour. This agent penetrates 3-5mm, thereby safely irradiating only the tumour. In this technique, detailed planning is required for the procedure and is to be performed only by experienced operators. It is a multistep procedure, which involves accurate volumetry, angiographic anatomical planning, shunt calculation with Tec 90, dose calculation,embolisation of the intestinal branches to prevent non-target embolisation, and final injection of the calculated dose superselectively into the tumour.This procedure has very few side effects, if done correctly, with very promising results. It is the treatment of choice in HCC palliation and with excellent results for liver metastasis. It can also be used in cases, where chemoembolisation is contraindicated- such as portal vein thrombosis, where radioembolisation can be used safely.Chemoembolisation and radioembolisation can also shrink the tumour, making them suitable for surgical resection. We have been pioneers in this technique in the country, with the largest experience with Yttrium 90. The protocol established by us in, conjunction with the nuclear medicine department, oncology and surgical oncology team, has helped us achieve results at par with international standards.Ablation Techniques:Ablation techniques are very promising for various tumours, with results equivalent to the gold standard, surgery. Various tumours such as HCC, bone tumours (osteoid osteoma,etc), renal tumours, lung tumours and breast tumours, which are inoperable, can be successfully treated by ablative techniques. The results are promising, offering a longer life span, better quality of life, pain relief and in some cases regression of the lesions.Various techniques are available, alcohol ablation for small (Radiofrequency ablation (RFA); a technique which involves the use of thermal energy, to kill the tumour cells. RFA is performed by using a needle to transmit heat and burn the tumour, rendering it inactive. We perform it, extrapolating the surgical technique, of ablating a 1cm normal tissue.Various tumours can be treated with RFA: HCC, liver metastasis, renal tumours, lung tumours, bony tumours and recent applications in the breast.
