After APL treatment: maintenance, follow-up tests and what to watch | CION Cancer Clinics
Whether you need maintenance after APL depends on the treatment you had. Many people treated with ATRA and arsenic trioxide need none. People treated with ATRA and chemotherapy often take tablets at home for a longer phase. Everyone has follow-up, with blood counts and the PML-RARA gene test to catch any return early. This page explains each step, what is checked, and the signs that cannot wait. At CION Cancer Clinics, every leukaemia, MDS and MPN case is reviewed by our haematologist and discussed at a tumour board before a plan is agreed.

The short answer
Will you need maintenance treatment after APL?
It depends on which treatment you had. Many people treated with ATRA and arsenic trioxide do not need maintenance at all. People treated with ATRA plus chemotherapy are often given a longer phase of tablets at home, followed by regular blood and gene tests.
What maintenance is
Maintenance is a long, lower-intensity phase that comes after consolidation, the courses that deepen remission. Its purpose is to keep any leukaemia cells that tests cannot see from growing back. It is usually taken at home, as tablets, with clinic visits for blood counts.
What follow-up is
Follow-up is for everyone, whatever route you took. It means planned visits, blood counts and the PML-RARA gene test, which can find APL at very low levels. The aim is to spot any return early, before it causes bleeding or low counts.
Who decides
Your haematologist chooses the plan from your risk group, the treatment you received and your gene test results. It is not something to change based on what another family was told. Two people with APL can follow quite different plans, and both can be right for them.
Never stop, skip or change a maintenance tablet on your own, even if you feel well. Call your team first.Side by side
How does the plan differ by the treatment you had?
After ATRA and arsenic trioxide
After ATRA and chemotherapy
Maintenance is often not needed once consolidation ends
Maintenance tablets at home are commonly part of the plan
Follow-up gene tests confirm the leukaemia stays undetectable
Gene tests continue through and after maintenance
Heart rhythm and liver checks during arsenic courses
Regular blood counts and liver tests while on tablets
Fewer long-term heart concerns from chemotherapy
Heart checks may continue, as some chemotherapy can affect it later
Not sure whether this applies to you?
Ask an oncologistThe pathway
What happens after the main treatment ends?
-
End of consolidation
A gene test is usually done around this point. A negative result means the leukaemia is no longer detectable, and it is the result your team is hoping for.
-
Maintenance, if it is part of your plan
You take tablets at home and come in for blood counts and liver tests. Doses are adjusted by the team according to those results, not by you.
-
Close follow-up in the early years
Relapse, if it happens, is most likely in the first years, so visits are more frequent at first. Gene tests may be done on blood or marrow, depending on your risk group.
-
Longer gaps between visits
As results stay steady, visits spread out. Many people move to routine blood counts and a yearly review.
-
Long-term health checks
Heart checks, vaccines, fertility and general health become the focus. Keep a copy of your treatment summary for any future doctor.
At each visit
What is checked at follow-up, and why?
Each test answers a different question. Bring every previous result, so trends can be compared.
Complete blood count
Haemoglobin, white cells and platelets. Maintenance tablets can lower these, and a falling platelet count can also be an early sign worth looking into. Reference ranges differ between laboratories, so one result is always read alongside the trend.
PML-RARA gene test
The most sensitive way to watch for APL returning. It finds the abnormal gene at levels far below what a blood count can show.
A single positive result is usually repeated to confirm it before any decision.Liver tests
Some maintenance medicines can strain the liver. Rising liver results may lead your team to pause or adjust a tablet.
Heart checks
An ECG or an echocardiogram, a heart ultrasound, may be advised.
Usually for people who had
- Arsenic trioxide courses
- Anthracycline chemotherapy
- Heart problems before APL

Signs that need care the same day
During maintenance or follow-up, a fever, new bruising, bleeding gums, tiny red spots on the skin, a heavy nosebleed or blood in the urine or stools needs urgent attention. Maintenance tablets can lower your counts, and these can also be early signs of relapse. Call your team, or go to the nearest emergency department or call 108 if it is severe. Do not wait for your next planned visit.
Commonly believed
What do people get wrong about maintenance and follow-up?
"The reports are normal, so the tablets are not needed."
Maintenance is given precisely when reports look normal. It works on cells that are too few to show up. Stopping early can raise the chance of relapse, so any change goes through your haematologist.
"Follow-up tests are just the hospital making money."
The gene test is how relapse is found before it causes bleeding. Catching it at that stage gives more treatment options and a safer start. Ask your team to explain what each test is for.
"We can switch to herbal medicine now that the hard part is over."
Some herbal and home remedies affect the liver or interact with maintenance tablets. Tell your team about everything you take, including supplements and Ayurvedic products.
"A positive gene test means the leukaemia is back in full."
A single positive result can reflect very low levels and is usually repeated. If it is confirmed, treatment at that early stage is often very effective.
Day to day
How do you live well during this phase, and what can this page not tell you?
Most people go back to work, college and family routines during maintenance and follow-up. Tiredness can linger, so build activity back slowly and rest when you need to. Worry before each result is very common, for patients and for the family members who drive them to every visit. Say so to your team. Knowing why each test is done, and what happens if one comes back unclear, often makes the waiting easier.
Practical things to plan for
Keep a small file of every report and a written list of your medicines. Ask your team before any vaccine, dental work or new medicine from another doctor. If you plan to travel, ask how to manage blood tests while away. Women thinking of pregnancy should talk to the haematologist first, because some APL medicines can harm an unborn baby.
What this page cannot tell you
It cannot tell you whether your plan includes maintenance, how often your gene test is due or what your latest result means. Those depend on your risk group and your reports. CION's haematology team can review your summary, explain the follow-up plan and coordinate specialised tests with qualified laboratories.
Questions we are asked
Common questions about APL maintenance and follow-up
How long does APL maintenance last?
When maintenance is part of the plan, it usually runs for well over a year, but the length depends on the protocol your team follows and how you tolerate the tablets. Many people treated with ATRA and arsenic trioxide have no maintenance phase. Ask your haematologist for your own expected end date.
Why does my father need blood tests so often if he feels fine?
Feeling well does not show what the blood is doing. Maintenance tablets can quietly lower counts or affect the liver, and an early return of APL often causes no symptoms. Regular tests let the team adjust treatment safely and spot a problem while it is still small.
Is the gene test done on blood or bone marrow?
It can be done on either. Marrow samples are more sensitive, so they are often used at key points such as the end of consolidation. Blood samples may be used more often during follow-up, especially for people in the lower-risk group. Your team chooses based on your risk and results.
What if we miss a maintenance dose?
Do not take extra tablets to make up for it. Call your treating team and ask what to do, and tell them at your next visit. Keeping a simple daily chart or a phone reminder helps, especially when an adult son or daughter is managing medicines for a parent.
Can I eat normally during maintenance?
Most people can eat a normal, balanced home diet. Wash fruit and vegetables well and eat freshly cooked food when counts are low. Some maintenance tablets are best taken in a particular way with respect to milk or meals, so follow the instructions your team gives you.
Can we do follow-up closer to home in the district?
Often, yes. Blood counts can usually be done at a good local laboratory, with results shared with your haematologist. The gene test needs a specialised laboratory, and sample handling matters, so ask your team where and how it should be sent.
When can we stop worrying about relapse?
The chance of relapse falls with every year of steady results, and it is most likely in the first years. Worry usually eases as visits spread out. Your haematologist can tell you when your own follow-up is expected to relax.
Will Aarogyasri or insurance cover follow-up tests?
Cover for follow-up and gene tests varies between Aarogyasri, PM-JAY, CGHS, ECHS, EHS and private policies, and the rules change. Keep your treatment papers ready and ask the helpline to check your current cover before the test is booked.
