Treatment Tidbits
The time from when a very pleasant Dr. D told my
hubby and myself that I have
acute
m-something-or-other leukemia until I was trundled off into my
own private Room #2 in the Advanced Cancer Unit and started treatment
was measured in hours, maybe minutes even. Not much time to
discuss treatment alternatives, nor even digest the fact that I had
Cancer. What follows is a description of the treatment I received
with links to both medical-ese and survivor-readable
materials. For some more technical topics (ie
cytogenetics),
the links are to medical journal articles or texts as the stuff
targeted at patients tends to be one-liners buried in brochures.
For medications, I have included links to
MEDLINEplus,
which offers information sheets published by two different sources,
MedMaster™, a product of the American Society of
Health-System Pharmacists (ASHP),
and the USP DI® Advice for the Patient®, from the United States
Pharmacopeia (USP). I've included both where possible.
The American
Cancer Society's Consumer's Guide to Cancer Drugs is very
helpful -- click on the "Guide to Drug" link on the left-hand side of
the page which will bring up the drug guide. CancerBACUP -- "Europe's
leading cancer information service" -- also has very readable drug
sheets. I'd read the sheets from either the ACS or CancerBACUP
first.
What kind of
leukemia is it?
AML can be typed into different categories which are
helpful in deciding how to treat the disease as well as determine the
prognosis. In my case, I had so many white blood cells running
through my veins that the doctor did not order a bone marrow biopsy
when I was admitted to the hospital. Instead, they were able to
roughly diagnose my type (
M2 or M4) by
looking at a blood sample.
Immediate
Treatment
Within hours I was given
hydroxyurea, an anti-metabolite
chemotherapy drug given as a pill (
MEDLINEplus,
American Cancer Society,
CancerBACUP)
along
with
allopurinol,
(
American
Cancer Society,
MEDLINEplus-MedMaster,
MEDLINEplus-USP
DI, ) which protects the kidneys from being damaged by
preventing an enzyme from producing uric acid as the leukemia cells
break down. Because I had extraordinarily high white blood counts
(175,000, or
hyperleukocytosis)
I needed to have as many white blood cells removed as possibly
immediately. A doctor installed a special line
in a large blood vessel in my leg and I was connected to a machine
which pulled out my blood, removed the white cells using a centrafuge,
and returned the rest to me, a process called leukapheresis.
Within a few hours my counts dropped to about 75,000; removing cells
meant fewer cells for my kidneys to deal with and less chance of
tumor
lysis syndrome, a complication that can arise as leukemia cells
break down from the chemotherapy.
Remission
Induction
Chemotherapy
The first phase of chemotherapy is referred
to as "remission induction", or induction for short, because the goal
is to beat back the cancer to a point where it is no longer causing
problems, ie remission. The next morning, prior to starting
chemotherapy, I was given a complete physicial, including an ultrasound
of my heart. They installed a central venous line, a Hickman
catheter (
CancerBACUP:
Managing a Central Line) under local anaesthetic and some mighty
fine drugs (I could still hear the retro radio station blaring and
people talking but hey, life was
DANDY! from under the blue
drape over my
head).
The main course, started later that day, was
heavy-duty traditional chemo, consisting of three days of
Idarubicin (
American
Cancer Society,
MedlinePlus)
combined with a total of seven days of Ara-C (cytarabine,
American
Cancer Society,
CancerBACUP).
Both
bone
marrow biopsies showed no sign of the leukemia, so I was
thankfully in remission. In addition, my marrow showed no obvious
changes in its genetic structure, referred to as normal
cytogenetics;
some changes are considered low risk, others high risk, and my normal
structure is considered intermediate risk or prognosis.
Consolidation
Chemotherapy
Induction kills off most of the
cancer cells, but not all of them. Consolidation chemotherapy
aims to kill off as many of the remaining bad guys as possible. I
was given "high dose" Ara-C (cytarabine), 3 grams per meter**2, for a
total of two cycles, and at 2 gms/m(2) for an additional cycle (that's
read as "grams per meter squared", which is a weird sounding
dimensional unit). This is a very standard treatment protocol
currently -- you can read descriptions
of chemotherapy at
American
Cancer Society.
I had to drop to the lower dose due to signs
of neurological poisoning. After my second cycle I had been home,
crashed out on the couch, and when I tried to get up felt like I had
been chugging beers. I couldn't walk a straight line, which is
one of the neuro tests the nurses do prior to giving each dose of
Ara-C.
I called my oncologist's nurse; at that point, there was nothing to do
other than watch and wait, and the balance problem stopped by the next
morning. Fortunately I remembered to remind my oncologist at our
meeting prior to starting the third round of chemo, and he decided
to lower the dosage.
Moral of
Story: Keep good notes of unusual (or even usual!)
symptoms and remember to tell your doctor about them. And
remember, just because I had neuro problems does NOT mean you or your
loved one will!
Neutropenia Nightmares
Neutropenia is no fun. When your white blood
cell counts crash following chemotherapy and the germ fighting
neutrophils sink below 0.5 (that's 500 cells per square
something-or-other, nobody ever talks about the units), your body is
very vulnerable to infection. MY body was very vulnerable to
infection, primarily from my own, home-grown bugs.
I came down with fevers of unknown origin two
(three?) times following induction. I also wound up back in the
hospital following all three consolidation rounds with fevers, usually
within 24-48 hours of my ANC hitting 400. The first round was a
mystery bug, but the next two were E. Coli sepsis, a very nasty
infection in the blood.
|
Please realize that just because I had lots of infections does NOT MEAN
you necessarily will. I am writing this partly for my own
benefit, to
realize that even though things were grim I bounced back.
This is also a cautionary tale -- if you start running a fever (your
doctor will tell you what they consider to be a fever, somewhere around
100.5 is typical) DON'T IGNORE IT! Call your doctor pronto, even
if
it's 2 a.m. That's their job, you are not bothering anybody. |
I wound up a human petri dish with that first round
of sepsis. I had been getting a blood transfusion in the hospital
wing around the corner from my usual 4 South home, when I noticed I was
feeling chilled. My temperature had been 99.3ish right after I
had swallowed some tylenol they always give for premedication.
Oops. I had this sixth sense that the medication could mask an
infection, and boy, was I right. By the time the blood finished
dripping and the tylenol wore off my temp was 103 and climbing. I
was incoherent by the time they moved me down the hall into the
advanced care unit. My temp maxed out at 105.1, and at one point
I remember stopping thrashing and moaning long enough to apologize to
my dear oncologist for being such a wimp (!). My blood pressure
crashed to 70 over something, so they maxed out the IV pump to 999 mls
per hour of saline, plus ___ to boost it back up, which also required
being on a heart monitor. I thought I was toast, but in a few
hours the shivering, thrashing, moaning misery backed off, and the
blood pressure/heart hiccups were fine in a day or so. But in
addition to the e. coli in the blood, my poor lips look like I'd been
in a fight (herpes virus, aka cold sores), my gut was upset from all
the antibiotics, so one of the unfriendly bacteria took over
(
Clostridium
difficile, a spore-forming bacteria) AND, to round things
out, a fungus in my lung. So I've taken at different
times:
Zosyn,
vancomycin,
Cancidas
(caspofungin acetate) for the
fungus, acyclovir for the virus, Flagel (for the C. Diff.), and so on.
The next round of sepsis, following the 3rd round of
consolidation, was not nearly as dramatic. My temp only hit
103.3ish, and I was under the weather for just a couple days. But
the urksome part of each post-consolidation infection is being cooped
up in the hospital for 10+ days and eating ...
hospital food!
Relapse,
Induction Chemo and Umbillical Cord Stem Cell Transplant
"We have a
problem" said my very kind Dr. D on March 11, 2004. My
white
blood count was up to 30,000, and the AML was back. I had hoped
for a longer vacation, but so it goes. My hubby and I went out
for Indian food that night, and I checked back into Chez Beige on
Friday,
March 12. It's April 6 as I write this, and I have a new Hickman
catheter, have gone through another week of induction chemotherapy
(Idarubicin and Ara-C), the E Coli and fungus returned, and I'm
twiddling my thumbs waiting for my counts to go back up.
Thank God for antibiotics -- the
Zosyn
and
Vancomycin
took care of the
E Coli, and the Cancidas is keeping the fungus in my lung at bay.
I'm scheduled to go to
Fairview/University of
Minnesota to start testing before a umbillical cord stem cell
transplant on April 12, assuming I have 1,000 neutrophils by
then. Stay tuned!
4/18/04 Update: Well, NOW I'm at home -- I
didn't get discharged until Friday, 4/16 because my counts were pokey
recovering, but that's not too surprising. People (aka the
hospital pharmacist, an oncologist or two or three or ) have said that
each time you beat up on the marrow it takes longer to recover, and it
took 31 days following the first induction last June. Wednesday
I'm off to see the doctor at the U of M and then the following week
I'll probably start all the testing. I feel well, other than the
wimpy legs, the iritis (inflammation of the iris, no correlation to the
AML) and the chemo brain.
5/14/04 Update: Day -4
I'm entertaining myself at Fairview/Univerversity while
the fludaribine drips by taking screen shots of my Hickman
Catheter. The nurse reviewing the slides was most impressed -- it
was inserted March 12 at Methodist and she pronounced it well placed,
so I didn't need to have it replaced. You can see the tubing
snaking into the heart on the Right side of my chest (x-rays are viewed
as if the patient is facing the reader).
8/7/04 Update Day 3/ Day 81
Now on a clinical trial using Natural Killer cells
and IL2. More later when my coordination returns.
Chemo Brain -- It's Not All In Your Head
Chemo brain, you know, it's that,
uh, well. What was I talking about?
Yeesh, some of the mental fog I struggle through I
know is exhaustion, especially in the hospital when I'm short on
sleep. Sometimes it's emotional overload, a bit of depression,
frustration at being cooped up, and the like. But yesterday my
hubby and I were heading off to hang out at a coffee shop, and I
completely, totally forgot the existence of a favorite joint where I
spent many hours writing a bad science fiction book. Poof!
Gone! Once he mentioned White Rock it all came back to me, but
not of my own initiative.
For me, I've had trouble remembering words,
finishing sentences when I speak, reading complex material (as opposed
to mind candy novels where it doesn't matter if I miss half the words),
problem solving, and juggling multiple tasks. Oddly, I can write
(like I'm doing now, directly into the computer) pretty well, but not
with pen & paper in my journal. The words get stuck. I
found these problems went away over time (like a month or two) after I
finished my consolidations, but are back in spades with the second
induction following my relapse.
I need to apply for Social Security Disability
Income soon (I'm scheduled for a cord blood transplant in the next few
weeks) and my biggest disability (other than the obvious being sick in
the hospital) is this fuzzy-headedness. I tried doing some work
for clients while I was in the hospital -- HA! Problem
solving? Pattern recognition? Critical skills I need in my
line of work (data management for health care research) were sorely,
uh, uh, cracking? No, no! LACKING! That was the word!
YOU ARE NOT CRAZY. Researchers
are finding that chemotherapy can
cause cognitive problems. And it's NOT menopause caused by the
chemo. The Wall Street Journal published an article
4/4/04ish about chemo brain and as I find decent links I'll add them to
this section. I'll also try to find stuff on how to cope -- I
know some of the cancer sites have tips, like keeping a TO DO list
handy to avoid forgetting tasks.
