Most brain cancer patients whose cancer has spread to the brain receive whole brain radiotherapy, in which two simple radiation beams on each side of the head are used to target the cancer. It also causes patients to lose the hair on their head. Doctors are experimenting with new types of radiation therapy to see if they are as effective in treating the cancer while preventing hair loss.
Doctors were able to improve upon whole brain radiation therapy in the patients under study, by using intensity modulated radiation therapy. Half of the patients in the study reported only slightly noticeable hair loss four weeks after treatment ended, and half had no noticeable hair loss.
"This new study will encourage doctors to consider using this new radiation technique to treat cancer that has spread to the brain," said Todd Scarbrough, M.D., lead author of the study and a radiation oncologist at the MIMA Cancer Center in Melbourne, Florida.
Tobacco and marijuana smoke differ in a number of ways, one notable example is that marijuana smoke contains tetrahydrocannabinol (THC), while tobacco smoke contains nicotine. Nicotine increases the cancer-promoting effects of smoke, while THC reduces cancer promoting effects, Melamede explained.
THC and nicotine act on related cellular pathways, but despite this fact, they bind to different receptors to activate these pathways. Cells in the lungs and respiratory passages are lined with nicotine receptors but these cells don't appear to have THC receptors. This may explain why smoking marijuana has so far not been linked with lung cancer, a major cause of death from cigarette smoking.
Research has also shown that marijuana kills cancer cells and reduces tumor growth. This is, in part, because marijuana reduces the formation of blood vessels that nourish tumors.
This news in no way should be comforting for a marijuana smoker since the effects of marijuana are complex and sometimes contradictory. Many people may use marijuana and tobacco together, and the two drugs could interact in complex ways.
While some governments are reluctant to approve marijuana for medicinal use, the review noted that there's increasing evidence that marijuana can improve the lives of patients with a broad range of health problems, including insomnia, AIDS, multiple sclerosis and Alzheimer's disease.
The integrated strategy is to focus on three critical issues related to lung cancer. These critical strategies include more effective tobacco control, improving likelihood of cure for lung cancer by developing methods of earlier detection and improving treatment of pre-malignant lung lesions and lung cancer with development of new targeted therapies.
NCI has the following recommendations to achieve this goal by the year 2015.
More effective tobacco control:
Emphasis will be given to development and testing of promising therapies for nicotine addiction. Research would be targeted to explore the genetics of nicotine addiction focusing on gene-environment interaction.
Focus will be given to develop more effective proteomic and expression technologies on tissues and bio-specimen samples. Effort will be directed at studying markers expressed on malignant tissues.
Priorities will be given to development of new drugs and understanding patient's response to therapy. The team has suggested research on the early cancer and pre-cancer microenvironment.

A study by Heitman and colleagues from Canada compares the costs and effectiveness of CT colonography to the conventional colonoscopy for screening. They found that screening 100 000 patients with CT colonography would cost $2.3 million more (in Canadian dollars) than with colonoscopy, and would avoid 3.8 fatal perforations, but at the same time, this method would lead to 4.1 cancer-related deaths from polyps not seen with CT, which would later become malignant. (Colonoscopy is slightly more sensitive than CT colonography, and could be expected to detect a certain number of polyps that the CT method would miss.)
New technologies are always attractive. Because CT colonography does not physically invade the body, it has even more appeal, it is easier for patients to accept. Its cost, however, is much higher, and its benefit (in terms of years of living that are gained) is only slightly lower than when colonoscopy is used.
Khanh H. Nguyen, M.D., lead author of the Fox Chase study and a resident in the radiation oncology department at Fox Chase said that men with type II diabetes didn't have a significantly different initial profile for their prostate cancer than the men without diabetes. The study did not detect significant differences in the initial PSA, Gleason score, or T-stage between the men with and without diabetes. Men with type II diabetes did not have significantly different treatment outcomes, said Nguyen.
Nguyen, now a radiation oncologist at the University of Tennessee Medical Center in Knoxville, Tenn., concluded, "The degree of hyperinsulinemia in type II diabetes can vary considerably and may obscure the true impact of insulin on the natural history of prostate cancer. "However, type II diabetes conferred a significantly higher overall mortality. Aggressive management of diabetes with diet, exercise, and medications may improve the survival of cancer patients."
According to a recent study presented at the American Society for Therapeutic Radiology and Oncology's 47th Annual Meeting in Denver almost half (48 percent) of cancer patients treated with chemotherapy and radiation are using at least one type of complementary and alternative medical therapy (CAM) treatment, a majority of them (75 percent) don't tell their doctor, even while receiving conventional cancer treatment.
The study shows that CAM use is almost twice as prevalent among patients treated by only chemotherapy (65 percent), compared to those treated by only radiation (35 percent).
"This study shows the significant lack of communication between patients and their doctors about the use of complementary and alternative medicines, like vitamins and herbs," said Neha Vapiwala, M.D., lead author of the study and a radiation oncologist at the University of Pennsylvania in Philadelphia.
"It's important for doctors to know about their patients' CAM use and to understand patients' reasons for using it, so that they can better tailor and optimize treatment regimens and improve patient quality of life during radiation and/or chemotherapy."

Cancer is a very common disease, approximately one out of every two American men and one out of every three American women will have some type of cancer at some point during the course of their life. Cancer is more common in the elderly and 77 percent of cancers occur in people above age 55 or older. Cancer is also common in children. Cancer incidence is said to have two peaks once during early childhood and then during late years in life. No age period is completely exempted from development of cancers. Some cancers occur predominantly in the elderly, other types occur in children, Cancer occurs in all ethnic races, however the cancer rates and rates of specific cancer types may vary from group to group. Late stages of cancer may be incurable in most cases, but with the advancement of medicine, more and more cancers are becoming curable.
