Results of international Phase III clinical trial for newly diagnosed brain tumors announced

In the randomized trial, “RTOG 0525 Phase III Trial Comparing Conventional Adjuvant Temozolomide with Dose-Intensive Temozolomide in Patients with Newly Diagnosed Glioblastoma,” no significant improvement in overall patient survival or disease progression was observed for patients who received the dose-intensive (dose-dense) TMZ plus radiotherapy as compared to patients who received standard-dose TMZ plus radiotherapy. The trial did however prove the feasibility of collecting and analyzing tumor tissue prospectively in a multi-center setting.

Curcumin compound improves effectiveness of head and neck cancer treatment, study finds

A primary reason that head and neck cancer treatments fail is the tumor cells become resistant to chemotherapy drugs. Now, researchers have found that a compound derived from the Indian spice curcumin can help cells overcome that resistance.

New drug target for squamous cell carcinoma

Researchers have discovered a new drug target for squamous cell carcinoma — the second most common form of skin cancer. Scientists have found that a protein called alpha-catenin acts as a tumor suppressor and they also have unlocked the mechanism by which this protein controls cell proliferation.

DNA repair system affects colon cancer recurrence and survival

Colorectal cancer patients with defects in mismatch repair — one of the body’s systems for repairing DNA damage — have lower recurrence rates and better survival rates than patients without such defects, according to a new study.

Herbal remedies offer hope as the new antibiotics

Cancer treatments often have the side effect of impairing the patient’s immune system. This can result in life-threatening secondary infections from bacteria and fungi, especially since bacteria, like Staphylococcus aureus, are becoming multi-drug resistant. New research investigates the potency of Indian wild plants against bacterial and fungal infections in the mouths of oral cancer patients.

Gene-modified stem cells help protect bone marrow from toxic side effects of chemotherapy

Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells. Researchers report that one possible approach to reduce this toxic effect on bone marrow cells is to modify the cells with a gene that makes them resistant to chemotherapy.

Droplets for detecting tumoral DNA

New research suggests it may be possible, in the near future, to detect cancer by a simple blood or urine test. Biologists from France have developed a technique capable of detecting minute traces of tumoral DNA present in the biological fluids of patients suffering from cancer.
