I had the honor of attending Chaya Venkat’s last meeting at
her house in Columbia, Maryland – that is, until she “gets her mojo back.” It
was really worth my while staying longer in the East Coast after my medical
appointment at NIH (National Institutes of Health).
Chaya, the chief science writer for
http://updates.clltopics.org/, is a
priceless patient advocate for leukemia patients with all different venues of
CLL/SLL. She gives relentlessly to leukemia patients. She has been my personal
virtual rock, since I was diagnosed with 17p deleted malignant B-cells that
have run amuck. She has been our voice, the layman’s translator of academic
medical jargon, and the inspiration for us to take control of our own health.
She has been the empress of all dragon slayers, but has grown weary in the
battle. Chaya has been wounded too many times with the deaths of friends. She
has held thousands of hands, and touched thousands of hearts. Now her heart
needs a little R&R and healing, so off to India she goes. There is not
enough love and gratitude to give back to that lovely woman. I personally will
be forever grateful. I pray every day that she gets her mojo back…
This blog posting is a summary of the meeting topics I found
most interesting to me. I am hoping this will inform those who are caretakers,
as well as those who are patients.
I. TOPIC 1:
DECISIONS ABOUT YOUR CANCER TREATMENT
A. When you enter a clinical trial, be aware of the informed
consent.
B. Once you make a decision, “do not look back and second
guess yourself, because therein lies madness…” (a quote from Chaya)
C. The buck stops with you the patient. You won’t be handed
information. Don’t take it personally. You must be your own advocate.
D. Understand that the suicide rate is the highest in the
oncology field. It can’t be fun watching people die.
II. TOPIC 2: FCO vs.
FCR vs. BR CHEMOTHERAPY
In summary, FCO appears to work better than FCR, and FCR
appears to work better than BR for most CLL/SLL patients.
A. FCO (fludarabine +
cyclophosphamide + ofatumumab)
Fludarabine (trade name “Fludara”) is a purine analog that relies
on a p53-dependent mechanism for cell kill; therefore, it is not as effective
for 17p deleted patients.
Cyclophosphamide is an alkylating agent.
Ofatumumab (Trade name Arzerra, older name Humax-CD20) is a fully
human protein that attaches to the CD20 marker. With previously treated
patients who were fludarabine refractory and Campath ineligible or refractory,
ofatumumab did seem to work better than Rituxan in clinical trials. Ofatumumab
hangs onto the B-cell longer.
B. FCR (fludarabine +
cyclophosphamide + Rituxan)
FCR is often referred to as the “gold standard.” This
frontline treatment has been used successfully for a number of years. This is
not a cure, however, and most patients will relapse after seven years.
Fludarabine (trade name “Fludara”) is a purine analog that relies
on a p53-dependent mechanism for cell kill; therefore, it is not as effective
for 17p deleted patients.
Cyclophosphamide is an alkylating agent.
Rituxan (rituximab) is a monoclonal antibody that is often
called “mouse juice,” since it is made from human protein and mouse protein. It
attaches to the CD20 marker.
C. BR (bendamustine +
Rituxan)
Bendamustine (Treanda) is a purine analog/alkylator hybrid
agent.
Rituxan (rituximab) is a monoclonal antibody that is often
called “mouse juice,” since it is made from human protein and mouse protein. It
attaches to the CD20 marker.
III. TOPIC 3: INFECTIONS
A. Bacterial infections
CLL/SLL patients get bacterial
infections if they do not have enough IgG in their blood work. CLL cells cannot
grow up to be healthy plasma cells. Pneumonia is caused by bacterial
infections. Therapy will not help IgG. The only drug that has made IGG levels
go up is Revlimid (Lenalidomide).
IgG can be replaced with IVIG ($10,000 per dose). Blood from as many as 10,000 donors could be used
to make a single batch of IVIG. IVIG is a blood product that is in short
supply. IgA and IgM cannot be replaced.
B. Viral infections:
T-cells work with viral
infections.
C. Clinical trial eligibility:
If a patient has been exposed to Hepatitis C, he or she is
not eligible to participate in most clinical trials.
D. People don’t die of CLL/SLL. They die of one or more of
the following:
1. secondary cancers
2. side effects of cancer treatment
3. pneumonia
E. How to prevent infections:
1. Have your Vitamin D3 level
checked by you GP. Remember that excessive Vitamin D is also toxic.
2. Chew Trident sugarless gum or
any gum with XYLOTOL. It is a sugar alcohol sweetener used as a sugar
substitute, and bacteria can’t eat it. It essentially starves your bacteria. Xylitol is actively beneficial for dental health,
reducing tooth decay to a third in regular use, and has been shown to reduce
the incidence of ear infections.
3. Get inoculated. Get a pneumonia
vaccine as soon as you are diagnosed. It works for five years. The longer you
wait to get this inoculation, the less chance you have of it working fully. Get
a flu shot every year, even if it has less of a chance of working as the time
from diagnosis goes by.
4. Break the habit of touching your
face.
IV. TOPIC 4: KINASE INHIBITORS and REVLIMID
A. Ibrutinib (PCI-32765):
This is the kinase inhibitor clinical trial in which I am
participating. NIH says that the drug will be FDA approved in 2-3 years. Chaya
believes it will be more like 5 years until it is commercially available.
A couple participants have reported iron deficiency and
being anemic due to gastro intestinal bleeding. This is a micro leak in the
G.I. track – essentially a small almost unnoticeable leak that adds up over
time.
B. CAL-101:
24% of the participants on the kinase inhibitor trial are
suffering from Grade 3-4 pneumonia, according to Chaya.
C. Revlimid (lenalidomide), a thalidomide analogue (which
caused limb abnormalities in babies when used during pregnancy) has proven to
be a disappointment in treating 17p deleted patients. Overall, it has caused
80% of participants to have Grade 3-4 hematologic toxicity.
V. TOPIC 5: BONE
MARROW
A. Pancytopemia means that the bone marrow is dead. This
occurs in late-stage CLL/SLL. Red and white cells, as well as platelets are
drastically reduced.
B. The white blood cell count and ALC (absolute lymphocyte
count), which is the sum of the B and T-cell counts, are not as important as
the infiltration of the:
1. bone marrow
2. spleen
3. liver
4. and lymph nodes
C. These counts are important for bone marrow health:
1. red blood count (normal range
3.93-5.22 M/uL)
2. hemoglobin (normal range 11.2-15
g/dL)
3. neutrophils (normal range
34.0-71.1%)
4. platelets (normal range 173-369
K/uL)
VI. TOPIC 6: HEALTH
TRIVIA
A. The basal temperature of a leukemia patient is abnormally
lower than the normal person. If a healthy person’s body temperature is 98.6
degrees Fahrenheit, a leukemia patient can have a full-blown fever at 99
degrees.
Take your temperature the same time each day for 2-3 weeks
and chart the results. This will be evidence to give your doctors to show your
lower body temperature.
B. Dental care is very important for a CLL/SLL patient.
Please inform your dentist that you are a leukemia patient. Let him or her know
about your treatment and side effects.
C. Types of cytopenia:
1. anemia = a deficiency of red
blood cells
2. Leukocytes, leucopenia, or
neutropenia = a deficiency of white blood cells
3. thrombocytopenia = a deficiency
of platelets
4. leukocytopenia = too low WBC
So these are the notes I wrote down at the meeting. These
were the topics that were of particular interest to me. I hope you will find
this information helpful to you.
Until my next posting … wishing you love and gratitude,
because after all… we are all in this together.
