For lakhs of brain cancer patients there is hope. A new technique in which the malignant tumour is completely removed with the help of a light–emitting chemical/dye –given orally to the patient six hours before surgery–promises to revolutionise treatment. Doctors at GB Pant hospital have used this technique successfully on a patient suffering from recurrent glioblastoma, the most common and aggressive form of primary brain tumour in humans.

"Total removal of a tumour is relatively uncommon with the naked eye or under the microscope. So the patient has to undergo recurrent surgeries. However, total excision of the tumour is possible now," said Dr Rahul Gupta, assistant professor of neurosurgey at GB Pant Hospital.

Gupta and Dr Ajay Sharma performed the new technique on a 32–year–old. Despite two surgeries, the patient’s malignant tumour was recurring fast. ‘‘This time, we tried to use the new technique wherein synthetically manufactured chemical/dye–5 aminolevulinic acid–was orally fed to her before the surgery. This chemical accumulates in the cancer cells and emits a light of a wavelength that is different from what can be seen through a microscope," Gupta said. When seen through a special microscope, the tumour appears pink. ‘‘The background is black and blue in complete contrast to the bright pink of the tumour, making total excision possible," the doctor said.

GB Pant is the first government hospital in India to have used this technique. Its neurosurgery head Dr Sharma said the cost of the dye–Rs 60,000–is a constraint but they were trying to procure it at cheaper rates through the government.
