There are too many lymphocytes in the blood, but there are no other symptoms of leukemia. Stage 0 is indolent (slow-growing).
Stage 0: The patient has lymphocytosis with more than 5000 lymphocytes per microliter of blood, but no other physical signs. Stage I: The patient has lymphocytosis and enlarged lymph nodes. The patient does not have an enlarged liver or spleen, anemia, or low levels of platelets.
Stage 0. The blood has too many white blood cells called lymphocytes. This is called lymphocytosis. The other blood counts are close to normal, and there are no other symptoms of leukemia.
While there is currently no cure for leukemia, it is possible to treat the cancer to prevent it from coming back. Treatment success depends on a range of factors. Treatment can include: chemotherapy.
It's important to note that the five-year survival rate for a patient diagnosed at stage 0 is 99 percent, according to the American Cancer Society.
There are many different types of stage 0 disease depending on the type of tissue in which it began. These include adenocarcinoma in situ (of the cervix, lungs, and gastrointestinal tract), ductal carcinoma in situ (of the breast), and squamous cell carcinoma in situ (of the skin, mouth, and larynx).
Mixed lineage acute leukemias
These types of leukemias may be called mixed lineage leukemia, acute undifferentiated leukemia, or, or mixed phenotype acute leukemia (MPAL). Most studies suggest these leukemias tend to have a poorer outlook than standard subtypes of ALL or AML.
If caught early, leukemia can be cured by undergoing several cancer treatments.
Stage 0 breast cancer. Stage 0 breast cancers are often called pre-cancers, pre-invasive cancers or breast carcinoma in situ. With stage 0, abnormal cells in the breast have some cancer characteristics, but they have not yet spread into other tissues or organs.
Even though Stage 0 breast cancer is considered “non-invasive,” it does require treatment, typically surgery or radiation, or a combination of the two. Chemotherapy is usually not part of the treatment regimen for earlier stages of cancer.
Number staging system
The number stages are: stage 0 – the cancer is where it started (in situ) and hasn't spread. stage 1 – the cancer is small and hasn't spread anywhere else. stage 2 – the cancer has grown, but hasn't spread.
More than 98 percent of patients who are diagnosed with stage 0 breast cancer survive at least five years after their original diagnosis. While a few patients will experience recurrences, the survival rates are still encouraging.
Ductal carcinoma in situ (DCIS) is the earliest stage of breast cancer, which is why it's sometimes referred to as stage 0 breast cancer. DCIS, by definition, is cancer that starts in the cells lining the milk ducts (carcinoma) and remains in the area where it originates (in situ).
Stage 4 cancer is not always terminal. It is usually advanced and requires more aggressive treatment. Terminal cancer refers to cancer that is not curable and eventually results in death. Some may refer to it as end stage cancer.
Although the overall prognosis may be poor based on cases with previous patients and older treatments, many patients with stage 4 cancer can live for years. A few factors to keep in mind: Many treatments are available to help fight cancer.
Surgery. Surgery is the main treatment for DCIS. Most women are offered breast-conserving surgery. If there are several areas of DCIS in the breast, doctors may do a mastectomy to make sure that all of the cancer is removed.
People in stages 0 to II may live for 5 to 20 years without treatment. CLL has a very high incidence rate in people older than 60 years. CLL affects men more than women. If the disease has affected the B cells, the person's life expectancy can range from 10 to 20 years.
Acute myelogenous leukemia (AML) is a cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made.
The cure rates and survival outcomes for patients with ALL have improved over the past few decades. Today, nearly 90 percent of adults diagnosed with ALL achieve a complete remission, which means that leukemia cells can no longer be seen in the bone marrow with a microscope.
