Oncology News and Research

RSS

Oncology, meaning bulk, mass, or tumor, and the suffix ''-logy'', meaning "study of") is a branch of medicine that deals with tumors (cancer). A medical professional who practices oncology is an ''oncologist''.

Nanoparticles image breast cancer

Current methods of detecting breast cancer suffer from low sensitivity, limited spatial resolution, or the need to use complicated and expensive radioisotope-based technologies.

Targeted nanoparticles boost arsenic’s anticancer punch

Arsenic trioxide has a long history as a potent human poison, but it also has proven valuable as one of the primary treatment options for acute promyelocytic leukemia. Efforts to use arsenic trioxide to treat other types of cancer are under way, but clinical trials are revealing that the extreme toxicity of this material is likely to limit its utility as a broad-spectrum anticancer agent.

Nanoparticle-based “chemical nose” sniffs out cancer earlier to improve treatment options

Using a "chemical nose" array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells. It is a tool that could revolutionize cancer detection and treatment, according to Vincent M. Rotello, Ph.D., M.Phil., and D. Joseph Jerry, Ph.D., M.S., the investigators who led the study.

New nanoparticles could revolutionize therapeutic drug discovery

Understanding the structure of proteins is a vital first step in developing new drugs, but to date, researchers have had difficulty studying the large number of proteins that are normally embedded in the cell membrane, a family of proteins that includes those involved in cancer-related signaling processes.

Discovery of new molecular pathway for targeting cancer

A UCLA study has identified a way to turn off a key signaling pathway involved in physiological processes that can also stimulate the development of cancer and other diseases. The findings may lead to new treatments and targeted drugs using this approach.

New drug compound Salirasib brings hope to pancreatic cancer patients

Every year, 42,000 Americans are diagnosed with pancreatic cancer. Few live very long, and less than 5% are still alive five years after diagnosis.

Thalidomide does not improve survival in small cell lung cancer

Treating patients with thalidomide in combination with chemotherapy for small cell lung cancer (SCLC) did not improve their survival but did increase their risk of blood clots, according to a new study published online July 16 in the Journal of the National Cancer Institute.

New discovery on DNA repair mechanism

Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.

Sunitinib shows promise for advanced kidney cancer patients with poor prognosis

Sunitinib prolongs progression-free and overall survival, and is safe and well tolerated in advanced kidney cancer (metastatic renal cell carcinoma) patients with a poor prognosis such as the elderly and those whose cancer has spread to the brain, finds an Article published Online First (www.thelancet.com) and in the August edition of The Lancet Oncology.

"Drops" of gold that burn tumors

At a technical breakfast, Romain Quidant presented his research into the detection and treatment of cancer using gold nanoparticles illuminated with laser light. Quidant, who was recently awarded the Fresnel Prize 2009 that recognizes the highest level of excellence amongst emerging researchers in the field of photonics, is an ICREA researcher at the UPC's Institute of Photonic Sciences (ICFO) and a fellow of the Cellex Foundation Barcelona.

Researchers investigate high-risk populations for bladder-cancer screenings

A new study by UT Southwestern Medical Center researchers sheds light on the challenges involved in identifying which high-risk population would benefit most from bladder-cancer screening.

New drug blocks common cancer pathway

Scientists have developed a new drug which can reduce the growth of tumours in mice by up to 98 per cent, according to a study published in Molecular Cancer Therapeutics ** this week.

Childhood cancer risk rises with mother's age

Research from the Masonic Cancer Center, University of Minnesota indicates that a baby born to an older mother may have a slightly increased risk for many of the cancers that occur during childhood.

Researchers grow immature egg cells in the laboratory for 30 days - could sustain cancer patients’ fertility

Researchers funded by the National Institutes of Health have completed a critical first step in the eventual development of a technique to retain fertility in women with cancer who require treatments that might otherwise make them unable to have children.

Two reproductive factors are important predictors of death from ovarian cancer

Researchers from the Centers for Disease Control and Prevention (CDC) found that survival among women with ovarian cancer is influenced by age of menarche and total number of lifetime ovulatory cycles.

Environmental manganese and cancer mortality rates

In the first ecological study of its kind in the world, a Wake Forest University Baptist Medical Center researcher has uncovered the unique finding that groundwater and airborne manganese in North Carolina correlates with cancer mortality at the county level.

Health reformers shy from proposals that would limit treatment options

In a story headlined 'In Retooled Health-Care System, Who Will Say No?' the Washington Post reports: "Although Obama and his advisers have held up providers' spending patterns as the crux of the crisis, proposals in Washington go only so far in addressing the thorniest questions about who gets what care."

Many breast cancer patients being kept in the dark on breast reconstruction

Despite the increase of breast reconstruction procedures performed in 2008, nearly 70 percent of women who are eligible for the procedure are not informed of the reconstructive options available to them, according to a recently published report.

Senior breast cancer patients receive ‘chemo’ if treated in private practices

In a study to determine the non-medical factors that may be associated with the decision to treat nonmetastatic breast cancer, researchers at Columbia University Mailman School of Public Health evaluated the association between oncologist characteristics and the receipt of chemotherapy in elderly women with breast cancer and found that they were more likely to receive chemotherapy if treated by oncologists employed in a private practice.

Discovery of genetic key to breast cancer's ability to survive and spread

New research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) sheds light on a genetic function that gives breast cancer cells the ability to survive and spread to the bone years after treatment has been administered.
