Bangalore, March 21
THE Manipal Comprehensive Cancer Centre and the Department of Nuclear Medicine at Manipal Hospital have introduced an innovative technique called ROLL (Radioisotope Occult Lesion Localisation) that will benefit people with breast lumps and early stage breast cancers.
Almost 25 per cent of cancerous breast tumours cannot be physically felt on clinical examination. After mammography or ultra-sonography, doctors need to accurately localise the tumour for successful surgical treatment.
Till date, surgeons use mammography or ultra-sonographic-guided needle or wire placement around the breast to locate these tumours. But the technique has some complications; often the wire is fractured and sometimes inaccurate localisation leads to false negative biopsies. Also, the needle placement is uncomfortable, with poor patient compliance.
The hospital's Department of Nuclear Medicine has invested in a special Gamma Probe to help surgeons identify and accurately remove the tumour.
ROLL is easier to perform, both radiological and surgical. It allows surgeon to identify the hot spot easily in three dimensions, giving greater flexibility in planning the incision. It is less painful compared to wire-localisation and can be performed as a day-care procedure.
