Gold nanoparticles paint a precise picture of brain tumors before and during surgery

By - April 15, 2012 1 Picture
Scientists at Stanford University’s School of Medicine have created nanoparticles that are able to precisely highlight brain tumors. Because the nanoparticles can be imaged in three different ways, they can be used to delineate the boundaries of tumors before and during brain surgery to ease the complete removal of tumors. The scientists have already used the nanoparticles to remove brain tumors from mice with unprecedented accuracy and hope the technique could be used on humans in the future. Read More

FDA approves the treatment of brain tumors with electrical fields

By - February 13, 2012 8 Pictures
The FDA (US Food and Drug Administration) has approved a new treatment for patients as an alternative to chemotherapy. The promising new non-invasive treatment by Novocure uses "Tumor Treating Fields" (NovoTTF) to treat cancerous growths and is now available for adult patients with recurring brain tumors (recurrent glioblastoma or GBM). The treatment delivers electric fields to a patient utilizing a portable, wearable device that permits the patient to maintain normal daily activities without down time. Read More

Miniature oxygen generator implants to boost effectiveness of cancer treatments

By - September 1, 2011 2 Pictures
Some cancers, such as pancreatic and cervical cancers, are notoriously hypoxic, which means they contain low oxygen levels. Because radiation therapy needs oxygen to be effective, hypoxic areas of a tumor can be difficult to kill. To combat this, researchers at Purdue University have developed and tested a miniature electronic device that is designed to be implanted into solid tumors to generate oxygen and boost the effectiveness of radiation and chemotherapy treatments.

Communicating nanoparticles that target tumors more efficiently

By - June 22, 2011 1 Picture
To minimize the toxic effects of chemotherapy, many researchers have been working to develop nanoparticles that that deliver drugs directly to tumors. But researchers at MIT claim that even the best of these nanoparticles are typically only able to deliver about one percent of the drug to their intended target. Now, a team has developed a new delivery system that sees a first wave of nanoparticles homing in on a tumor that then calls in a larger second wave that dispenses the cancer drug. In a mouse study, the new approach was found to boost drug delivery to tumors by over 40-fold. Read More

Hope for quicker, more accurate cancer cell identification

By - November 26, 2010 1 Picture
Not many things are tougher than dealing with a diagnosis of cancer. But often the protracted wait for biopsy results, and the uncertainty surrounding them, can be excruciating for patients and their loved ones. Now a research team at the University of Illinois has developed a tissue-imaging technique that produces easily identifiable, color-coded images of body tissue that clearly outline tumor boundaries. What’s more, the process takes less than five minutes. Read More

Cheek swab technique could provide simple cancer screening

By - October 13, 2010 1 Picture
Early detection of lung cancer is vital for increasing a patient’s survival rate and to prescribe the best form of treatment. Now New York researchers have developed an early detection method involving a simple cheek swab. Called partial wave spectroscopic (PWS) microscopy, this new technique involves shining diffuse light on cells from the swab. The test is able to distinguish individuals with or without lung cancer, even if the patient has been a lifelong smoker or suffers from other smoking related illnesses. Read More

3D imaging technique provides clearer roadmap to remove deadliest form of skin cancer

By - August 11, 2010 3 Pictures
Even though melanoma is one of the less common types of skin cancer, it accounts for the majority of skin cancer deaths – around 75 percent. The five-year survival rate for early stage melanoma is very high (98 percent), but the rate drops precipitously if the cancer is detected late or there is recurrence. So a great deal rides on the accuracy of the initial surgery, where the goal is to remove as little tissue as possible while obtaining “clean margins” all around the tumor. So far no imaging technique has been up to the task of defining the melanoma's boundaries accurately enough to guide surgery – until now. Read More

Non-invasive infrared scanner to detect deadly melanoma

By - February 28, 2010 2 Pictures
Although melanoma is one of the less common types of skin cancer, it is responsible for the majority (around 75 percent) of skin cancer related deaths. Part of the problem is that current diagnoses rely on subjective clues such as size, shape and coloring of a mole. With the aim of providing an objective measurement as to whether a lesion may be malignant, researchers at John Hopkins University have developed a prototype non-invasive infrared scanning system that works by looking for the tiny temperature difference between healthy tissue and a growing tumor.

Nanosized drug delivery systems take a leap forward

By - November 3, 2009 1 Picture
Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer. Read More
