General roughly divided into acute and
chronic leukemia , both of which they can be roughly divided into lymphoid and
myeloid .
The first mention of chronic
lymphocytic leukemia :Most of
the patients have the disease usually is older , so the main goal of treatment
is to treat the symptoms -based, and the average survival rate of leukemia, such
as five years , but there will be people who survived more than a decade
.
Chronic myeloid leukemia :Occurs in about 40-60 years of age, but
there are other age groups also may occur . General
symptoms are slowly emerging , including malaise , night sweats , weight loss,
bone pain and even the case , if the younger person may be given oral
chemotherapy drugs , when reached remission (remission) and then consider the
use of bone marrow transplantation ,
but because the disease is not easy to quit , so now there is a way to control
the chronic into acute leukemia drugs - interferon (α-interferon), the
therapeutic effect of such drugs has been affirmed , there can be about 70% -80
% of
patients achieved remission effect, but survival was also extended to seven
years , so the younger patient is encouraged if suitable matching donor bone
marrow transplant patients , older patients , you can use interferon (
α-interferon) to
treat, usually about one year after treatment to know its effectiveness , but
whether it can cure patients , remains to be more long-term observation
.
Acute lymphoblastic leukemia
:Major
often occurs in children , but the symptoms have pallor , anemia , fatigue and
asthma cases have occurred , as the treatment approach in children treated with
chemotherapy compared with 70 percent chance of cure , while adults have the
disease but also the first for
chemical treatment , such as remission ( ie clinical examination or can not find
some basic blood cells termed ) further bone marrow transplant to treat, but
because the disease often violated central nervous system , it is required to do
the prevention and treatment of central nervous system current prevention
method is to use radiation therapy or intrathecal intracranial a chemical
treatment, and such treatment is indeed proven to prevent the recurrence of CNS
. In
addition to doing remission induction chemotherapy , but still want to do when
consolidation therapy after remission and maintenance therapy to reduce the
chances of relapse , treatment is usually for about three
years.
Acute myeloid leukemia
:With acute
lymphoblastic leukemia is not the same is that the disease is rarely violated
the central nervous system , so I do not need to be the central nervous system
prophylaxis. The principle of treatment
of acute lymphoblastic leukemia treatment is the same , if the condition being
treated well and sometimes maintenance treatment is not made . To special note
is the third subtype of this disease is the use of A acid derivative (ATRA) to
treat, there will be about 80% of patients achieved remission results.
When used with
chemotherapy and ATRA simultaneously or subsequently granted , long-term
disease-free survival will reach 60%.
