LITT Nanoparticle Technology – New Cancer Treatment Shows Promise

A group of investigators at the Wake Forest Univ. Baptist Medical Center lately made an announcement that they have made noteworthy improvement in an investigational cancer treatment called LITT (laser-induced thermal therapy). The LITT treatment involves introduction of nanoparticles to the region surrounding the tumor after which laser treatment is employed for heating these nanoparticles and destroying the cancer-ridden tissues.

Study investigators from Wake Forest fine-tuned the therapy by employing iron-comprising MWCNTs (multi-walled carbon nanotubes – strands of hollow carbon which are ten thousand fold finer in comparison to a hair in humans) that could be traced inside the body of a patient via the usage of Magnetic resonance imaging (MRI), thus facilitating improved precision delivery of laser therapy and thus enhanced targeting of neoplastic tissue.

The study finding was presented by Xuanfeng Ding, M.S. during the fifty-second AAPM (Annual Meeting of the American Association of Physicists in Medicine). During lab trials, the research group exhibited that a MRI scanner could be used for imaging such particles in animate tissue, observe as they approach a tumor, scorch them using a laser and annihilate the tumor in this process.

In case this sounds like Sci-Fi, it surely isn’t as the work is designed on an investigative method for cancer treatment- LITT. LITT functioning is based on the principle that particular nanoparticles such as MWCNTs could soak up energy from the laser and then transform it to heat. In case zapping nanoparticles while inside the tumor could be done then they would simmer off the energy as heat and obliterate the cancer cells.

But a minor snag with LITT is that even as a tumor could be noticeable lucidly during medican scans, the same is not true in case of nanoparticles. Following administration via shot form, such nanoparticles cannot be traced that might endanger the patients in case nanoparticle zapping is done far the tumor since the abnormal heat can obliterate normal tissues.

The Wake Forest Baptist group have proven for the foremost instant that the nanoparticles could be made noticeable during MRI scanning to facilitate imaging and scorching at the analogous instant. When the MWCNT particles are loaded with iron, they could be easily spotted in during MRI scanning. Employing tissue comprising of rodent tumors, the researchers were able to show that such iron-comprising MWCNT particles could obliterate the tumors after being knocked off with the laser.

Dr. Ding pointed out that to locate the precise site of nanoparticles in the body of humans is critical to therapy. He stated that it was truly enthralling to observe the nanotube labelled tumors start shrinking following therapy.

The outcomes are a segment of the multidisciplinary project carried out by Ding and helmed by Suzy Torti, Prof. of biochemistry, Wake Forest Univ.

An earlier research conducted by this team had shown that laser induced therapy treatment employing a closely-associated nanoparticle, in fact, augmented the long-standing survival in rodent tumors. The subsequent approach by this team is seeing whether the iron-contained nanoparticles could do the analogous thing.

In case this work turns out to be a success, it might be helpful for cancer patients in future, although the technology would have to be proven risk-free and effectual in scientific studies.
