I have gathered the cancer research news from Google and National Cancer Institute. Lung Cancer Statistics 2009 Below are some of the new findings of cancer treatment which I found really benefits to the world.

1. New Cancer Treatment without Surgery

On the 27th of January 2009, U.T.'s Health Science Centre unveiled a new promising cancer treatment that revolutionized the way to treat cancerous tumors in patients' lungs. After mild sedation, a catheter is inserted into patients' throat and the lung near to the tumor. Radiation is released from a small seed at the end of the catheter and killed the tumor cells without killing the normal lung tissue. Therefore, the patient can still live normally after treatment. It only takes 3 to 4 minutes to undergo this treatment and the patient can leave the hospital a short time later without feeling sick.

2. Machine Boots Cancer Treatment

On 12th of June 2009, a new machine that can speed up cancer treatment for cancer patients has been unveiled. This machine enables an extra 200 radiotherapy cancer treatments to be carried out every week. It generates high intensity of radiation beams to kill cancer cells effectively.

3. CD8+ Memory Stem Cells to Destroy Large Tumors

On 14th of June 2009, the researchers at the National Cancer Institute found that a subset of immune cells, T lymphocytes called CD8+ memory stem cells, were capable of mediating strong anti-tumor immune response. These stem-like characteristics of CD8+ memory stem cells enable tiny numbers of T cells to stimulate the destruction of large melanoma tumors. The CD8+ memory stem cells have the enhanced ability to renew themselves, to proliferate, to differentiate and to kill tumor cells effectively.

4. ?-CbT - Compound Inhibited Nicotine Receptors for Cancer Treatment

On 15th of June 2009, the compound ?-CbT was found to inhibit the expression of nicotine receptors and increased apoptosis. As we all know, changes in genes encoding nicotine receptors can drive the urge to smoke and increase susceptibility to lung cancer as well. Exposure to nicotine will boost the expression of nicotine receptors which inhibits the apoptosis. Therefore, this new cancer treatment that targeted nicotine receptors by using ?-CbT can prevent the developing of lung cancer. The ?-CbT did not affect the noncancerous cells.

5. microRNA - Help Identify and Cancer Treatment for Lung Cancer

On 7th of October 2009, the scientists at National Cancer Institute revealed that a small RNA molecule, known as microRNA, can help to identify liver cancer and respond well to cancer treatment with a biological agent called interferon. The researchers showed that miR-26 (microRNA) status in tumors may be useful indicator both to determine prognosis for patients with hematocelular carcinoma (HCC) and to inform the selection of patients who might benefit from treatment with interferon to prevent disease relapse.

6. Suicide Gene - Induce Apoptosis on Tumor cells

On 9th of October 2009, A group of researchers from National Cancer Institute have used the suicide genes that cause a cell to kill itself through apoptosis to treat cancer. This new technique used the surviving gene promoter to induce the expression of suicide gene in cancer cells with a minimum effect on normal cells. When the survivin promoter-driven mutant bax was injected in to tumors of mice, the gene induced 60% of cancer cells in tumor tissue to undergo apoptosis. This slowed tumor growth significantly.

7. Reduce Radiation Damage by Blocking the Expression of CD47

On 21st of October 2009, the researchers at National Cancer Institute once again showed their contribution to the cancer research by developing a method that protects healthy tissues from damaging effects of radiation cancer treatment. Previous cancer research showed that mice lacking CD47 are resistant to radiation damage. Therefore, the researchers injected an agent that suppressed the CD47 expression during the radiation. They proved that this can protect the normal cells from damage by radiation.

8. Nicotine Patch and Nicotine Lozenge Works Best for Smoking Cessation

On 2nd of November 2009, the researchers from National Cancer Institute showed that the combination of nicotine patch and nicotine lozenge provided the great benefit for smokers to quit smoking effectively.

9. PDF - Mushroom Extract that Shrink Tumors Effectively

On 1st of December 2009, Dr. Brandon Louie and colleagues from Department of Urology at New York Medical College showed that a combination of interferon alpha (immunotherapy for bladder cancer) and PDF (mushroom extract) can reduce bladder cancer cell growth. However, it is too soon to claim that the PDF are a cure for cancer as the study provides no evidence that the mushrooms extract have health benefits in humans. Anyway, I still feel that this study has the further research value for cancer treatment in future.

10. Lunasin - Fighting Leukemia and Blocking Inflammation

On 2nd of December 2009, Elvira de Mejia, a professor of Food Science and Human Nutrition from University of Illinois claimed that lunasin, a soy peptide may have important benefits that fighting leukemia and blocking the inflammation that accompanies such chronic health conditions as diabetes, heart disease and stroke. Lunasin is a soy peptide often discarded in the waste streams of soy-processing plants.

In conclusion, the cancer research on cancer treatment is still has a long way to go. The cancer research will continue to carry out to provide the greatest benefits to the world.

Do you know any new discovery of cancer treatment in 2009 that I do not mentioned above? Please leave your comment to provide us a great resource of information.
