Leukemia Survival Rates Improve with New Treatment Methods
The 5 year-survival rates for patients with leukemia has increased 400 percent over the last 50 years. This substantial increase is due to improvements in traditonal treatment methods of chemotherapy, radiation and stem cell transplantation, as well as development in the newer fields of immunotherapy, and targeted drug therapy.
In the early 1960s, one in seven leukemia patients survived longer than 5 years. Today, that number is better than 1 in 2 and will probably improve with further advancements in the new treatment methods mentioned above. While most people unaffected by cancer are familiar with the concepts of chemotherapy and radiation, the new fields of immunotherapy, targeted drug therapy and stem cell transplantation are less understood.
Immunotherapy: Also called biological therapy and biotherapy, immunotherapy is a young treatment field that aims to fight off cancer by using natural substances that encourage the body's own immune system to identify and fight off cancer, or, laboratory made substances (that are similar to our body's own immune system components) to defend the body against cancer without the help of the patients own immune system. These "natural substances" and "lab made components" are not called drugs or medication. Instead, they are known as Biological Immune Response Modulators (BIRMS), and sometimes referred to as immunomodulators. The main types of BIRMS are interferons, interleukins, monoclonal antibodies, cancer vaccines and nonspecific nonspecific immunomodulating agents. BIRMs are often geared towards helping white blood cells (which fight off disease and infection), and special cells in our body called antigen-presenting cells (APCs). Antigen-presenting cells help identify unwanted cells and molecules by attaching themselves to them, and then presenting them to white blood cells. When presented, the APCs tell white blood cells that they should destroy any cells that like the one they are attached to.
According to the American Cancer Society, immunotherapy is still a small field which hasn't yet proven itself to be better than other types of cancer treatments. However, it's one that researchers say holds a lot of promise and is expected to provide many new advancements in the fight against cancer.
Many immunotherapy agents are of the monoclonal antibody type (MAB) and so are many targeted drug therapies. These two fields overlap when it comes to MABs. Immunotherapy is being applied and researched to many different types of cancer. With leukemia, besides MABs, interferon alfa is the most prescribed BIRM and is adminstered to patients with chronic types of leukemia.
Targeted Drug Therapy: Targeted drug therapy is also a new field which has many features that overlap with immunotherapy. Targeted therapy is an umbrella term that describes a new class of medicines which aim to halt or prevent new cancer cells from forming by stopping specific molecules and cells that assist new cancer cells in growing and dividing uncontrollaby. So far, targeted therapy has had more success than immunotherapy with the introduction of new drugs that have become first and second line treatments in the fight against leukemia. Since these medicines only target specific cells, their side-effects are considered less severe than chemotherapy and radiation which targets cancer cells and healthy cells.
Targeted therapy drugs used in the first rounds of leukemia treatment (along with other methods) include: Imatinib, Nilotinib, and Dasatinib. Targeted therapy drugs used in the second round of treatment or after leukemia has returned from remission include: Tretinoin, Rituximab, Alemtuzumab, and Ofatumumab.
Extensive research of these BIRMs and targeted therapy drugs are being conducted on different types of leukemia and are moving through the clinical trial process.
Questions and Answers
Leukemia is a termed as a serious cancer that occurs in the tissue that forms blood cells. Leukemia causes the bone marrow to produce abnormal white blood cells which are known as leukemia cells. These cells don’t die when they should and moreover causes damage to the normal cells by stopping their nature of work.
Blood cancer therapy is the key element in eliminating abnormal cell-growth in the white blood cells present in blood. It can be of various intensities.
Cancer which is found in the lungs is termed as lung cancer. Lungs are the softy organs located in the chest on both either side of the heart. Lungs are the essential organs useful in supplying oxygen in the blood to various parts of the body. Lung cancer is referred as the malignant tumor because it spreads through out the body, lung cancer cells usually travels through blood vessels into tissues and lymph nodes
Discounted cost of leukemia treatment in India is one of the important reasons, why international patients prefer to have their leukemia treatment in India.
Though in recent years chemotherapy, the term coined by the German bacteriologist ‘Paul Ehrlich' when he envisioned "magic bullets" that could target invading organisms and leave the host unscathed, has become a popular form of anticancer treatment, virtually all cancer chemotherapy is a delicate compromise between effectiveness and toxicity, resulting in significant side effects.
Cancer translational research brings together scientists' and clinicians' suggestions to develop solutions to biomedical complications. This kind of applied research strives to offer strategies to questions surrounding the etiology, pathology, diagnosis, prevention and treating cancer.
Orbs are actually a lumpectomy or quadrantectomy combined with rotating the breast tissue or mobilize the flap into the cavity of the surgery time fill is removed. It also includes the comparative change in shape and size is doing in relation to breast and moved if necessary, does not affect the conversion of the breast. The deferred plan the reconstruction is not part of endoplasmic techniques. Both procedures are performed by specific thoracic surgeons.
What every woman fears for is losing her self confidence , losing hope and losing her personality. The term "Breast Cancer" is a very negative word and that it creates negative vibrations in her heart. So, to make her comfortable with the basics of breast cancer and to make her means any woman understand that this type of cancer is the least dangerous than all cancers and that if it is detected early then you will fight with it successfully. Causes, Symptoms, treatment, discussed in detail.
Mesothelioma is a rare cancer that originates in the mesothelium. The mesothelium is the protective lining that covers the body's internal organs. Mesothelioma occurs when the mesothelium cells start to divide uncontrollably.
Chemotherapy is a treatment for killing cancerous cells which is given intravenous or extra-venous to the cancer patient. Even breast cancer patients have to go through the treatment. This treatment mainly focuses on the cancerous cells that are spread in the blood stream in the whole body . If any cancerous cells are there then they are killed by the chemotherapy medicine. The medicine is very costly and it has to be taken for one or two days continuously for every 21 days .
