What factors affect the level of neuroblastoma survival?
Two factors that affect the level of neuroblastoma survival are the child's age and how far cancer has spread. In some cases, very small children can either disappear without treatment, or can enlarge and create non -lawyer growth that can be surgically removed. Younger children generally have a better prognosis than older. In children of any age, if the tumor is diagnosed very soon before it spread, the level of treatment is over 90 percent. The long -term forecast of this type of childhood cancer deteriorates to the extent that the tumor has advanced. It can be completely surgically removed and all lymph nodes are without cancer. The level of neuroblastoma survival at this stage is more than 90 percent.
Phase 2a categorizes a tumor that is not easily removed, but is present only on one side of the body. All lymph nodes are without cancer. Stage 2b tumor is still on one side of the body, but lymph nodes on the same side of the body are affected. Lymph nodes on the opposite side arewithout cancer. Phase 2 of the neuroblastoma survival in patients aged one year will vary from 75 to 90 percent.
Malignant tumor can be categorized as stage 3 for various reasons. It is placed in this category if it spreads and is located on both sides of the body, with or without lymph nodes on both sides. When doctors refer to cancer on both sides, they mean that it is on both sides of the imaginary line attracted by the center of the body. The tumor is also marked as Phase 3, if it is on one side of the body, but is located in the lymph nodes on the other side. The level of neuroblastoma survival in patients in phase 3 and phase 2b is about 50 to 70 percent if they are older than one year of age, and about 80 percent if younger.
Phase 4 tumors concerns those that proceeded to influence lymph nodes, bone marrow and other organs. Phase 4s applies to infants who have a tumor only on isthe bottom of the body, but which has spread to other organs. The level of survival of neuroblastoma in phase 4 and 4s in patients under years is 50 to 80 percent, while the rate in patients in one year is 10 to 40 percent.
