According to a study presented by researchers at Thomas Jefferson University Hospital a rapid decline in metabolic activity on a PET scan after radiation therapy for non-small cell lung cancer is correlated with good local tumor control. In addition, the researchers also found that the higher the metabolic activity and tumor size on a PET scan before treatment, the more likely a patient is to die from lung cancer.

A research conducted at University of California Irvine Medical Center has developed a new therapy that, if delivered endoscopically, in combination with radiation therapy and chemotherapy, can prove beneficial for patients suffering from advanced esophageal cancer. The new biological therapy (TNFerade), in which an agent preventing tumor is injected, was tried on 24 patients of the highly fatal form of cancer. The treatment has a non-replicating virus, engineered to deliver the gene for a protein that fights cancer.

A recent study conducted at Fox Chase Cancer Center, Philadelphia indicates that men with early prostate cancer whose PSA (prostate-specific antigen) levels have doubled within 6 months of radiation therapy benefit significantly from a hormonal therapy, if initiated sooner. The findings of the research team suggest that the benefit of immediate use of androgen deprivation therapy (ADT) was more in patients whose PSA doubled within 6 months than in patients whose PSA had longer doubling times.
