DAY +8: Speedbump

Top Line: While she was at Dana Farber today for her infusion and injection, Susan developed severe stomach pains. As I write (10:00 PM), she's being prepped for a CAT scan with contrast. There is still no diagnosis, hence the scan. Once the doctors know what the problem is, they will be able to treat it appropriately.

Susan and Bob went to DFCI this morning for her usual vancomyicin infusion and neupogen injection, as well as for a consult with Nurse Amy (Dr. Soiffer's Nurse Practitioner). They met with Amy while Susan was being infused and reviewed the most recent bloodwork and Susan's progress vs. expectations. Everything was on track.

In particular, her white count was down to 1.4, which suggests that the bottom is near. We won't know until the count starts back up. The question of any need for platelets or whole blood is still open and will depend on her "numbers," but it is fairly common for this treatment to become necessary and is no cause for alarm.

Also, her bloodwork showed some CMV (Cytomegalovirus), which is a fairly common and treatable condition, and she is being treated.

The problem began around the time that Susan was finishing up with her infusion. She developed severe stomach pains very quickly and out of the blue. Normally, she would have had her neupogen injection at that point, but she waved it off due to the pain, for which she was put on morphine. Dr. Soiffer was called in to examine her but he was not able to tell what was causing the pain except to note that it was not a known complication related to her disease or treatment regimen.

I can't tell you why it took all afternoon and well into the evening to get to the point where they are doing the CT scan, but it did. The good news is that Susan's pain has subsided considerably over the past couple of hours, but they don't know why. She's now in the hour-long process of drinking a gallon of the foul barium-based liquid that supplies the contrast for the scan. Then she'll have the scan. Then a radiologist will interpret the scan, and at that point it will likely be after midnight. Based on what they find and how she feels, she'll either be admitted or return to the apartment.

As soon as I learn more, I'll post it. If there's anything really serious, Bob will call me regardless of the hour. Otherwise, I'll get an update in the morning and post it post haste.

Hi Susan, We have just returned from Knoxville and weren't able to access the blog there. But you have been and are in our thoughts and prayers for a speedy and full recovery! I am also sending a card to your Boston apt - the blog didn't mention cards along with the items not to send - but if its a no-no, just have someone intercept it. All our love, Becky and Michael

Susan's disease

Chronic Lymphocytic Leukemia (CLL) is a slowly progressive form of lymphocytic leukemia, characterized by an increased number of B lymphocytes, one of 5 types of white cells in the marrow and blood (hence the concern when white cell counts are elevated). The role of B lymphocytes is to produce antibodies to help combat infectious agents such as bacteria and viruses. With CLL, B lymphocytes multiply unchecked and, in the absence of threats to combat, will attack healthy cells and tissue. It is common to experience enlargement of the lymph nodes and spleen as the disease progresses. CLL is the most prevalent form of leukemia and occurs predominantly after age 55, although Susan, ever the precocious one, was 50 when she was diagnosed.

Susan's diagnosis came in December, 1999, when routine bloodwork revealed an abnormally high white count. After evaluating the several world class cancer centers in the US, she settled on Boston's Dana Farber Cancer Institute (DFCI), affiliated with Harvard Medical School.

Susan was fortunate to be introduced by mutual friends to Dr. Lee Nadler, a Senior Vice President at DFCI and Professor of Medicine at Harvard Medical School. Dr. Nadler, who does not normally take on a patient load, agreed to become Susan's primary oncologist and has, over the years, arranged for her to see the appropriate specialists as needed, whether at DFCI or other institutions.

Susan underwent a regimen of chemotherapy from May through September of 2001 which provided her a strong remission lasting until the Spring of 2005, when elevated bloodcounts indicated that additional treatment was required. Tests revealed that the locus of the disease at that point was in her spleen, and she underwent a successful splenectomy operation in August 2005, enabling her to reestablish her remission.

Of course, there's a wrinkle. Over the past couple of years blood sample analyses have shown the presence of both Hodgkins Lymphoma and non-Hodgkins Lymphoma cells, suggesting that the disease has been morphing, muddying the waters as far as a clearcut diagnosis is concerned. There is no label for what Susan has (we are calling it a variant of CLL, for simplicity's sake). However, it doesn't really matter. The course of treatment at this point is the same: a stem cell transplant.

Although Susan has been fortunate enough to be essentially asymptomatic all these years, her white cell counts have gone up as high as 320,000, only to be brought back down to a reasonable level through chemotherapy. To put that number in perspective, a healthy individual's count usually ranges between 4,000-10,000. The fact that she doesn't look sick and generally feels fine does not mean that she doesn't have a serious and progressive illness.

From the beginning, Dr. Nadler had indicated that at some point the disease would advance to where the best course of action would be a transplant procedure, which is dangerous but potentially curative. That point is now.

Susan's Transplant Procedure

RATIONALE for the TRANSPLANT

While the right protocol of chemotherapy can produce a remission in patients with blood cancers, these remissions are almost always temporary, not curative. The number of remissions a particular patient's disease may enable him or her to realize is very limited - sometimes only one, sometimes several - but in general any successive remission(s) is less robust and of shorter duration. The time comes when the best approach is to go for a cure, which is what a successful blood and marrow stem cell transplant can offer. The transplant entails significant risks (as outlined below), but Susan is at the point where the benefits of another remission (if successfully achieved) might be fleeting and leave her less able to tolerate the transplant at some future date.

BLOOD and MARROW STEM CELL TRANSPLANTS: the SHORT COURSE

Blood, despite its homogenous appearance as a red fluid, is actually a very complex medium that contains many different factors, all of which are generated by a person's bone marrow. In a blood cancer like Chronic Lymphocytic Leukemia (CLL) these components of the blood become unbalanced. A person with CLL produces an ever increasing quantity of white cells in the blood over time, particularly B lymphocytes.

White blood cells , including lymphoctyes (B lymphocytes, T lymphocytes, et al.) act as the body's defense against infection and other foreign bodies, and so they naturally increase to combat such threats, but when the threat has been eliminated, the white cell count returns to its normal level. To oversimplify, elevated levels of white cells, pumped out by malfunctioning bone marrow, with no disease or infection to neutralize, begin attacking healthy tissues and systems. This is the case when a person has CLL.

If the bone marrow which produces the white cells can be restored to its proper functioning, then the white cell count will return to normal. A blood and marrow stem cell transplant can achieve this by largely destroying the sick person's marrow through chemotherapy and/or radiation and then replacing it with healthy marrow. To be more accurate, it is not the physical marrow which is destroyed and replaced but rather stem cells within the marrow responsible for the production of red cells, platelets, and the various kinds of white cells, including the lymphocytes. Therefore, the procedure is most accurately called "Blood and Marrow Stem Cell Transplantation" or Stem Cell Transplantation, although it is often referred to loosely as a Bone Marrow Transplant since the diseased marrow is being regenerated via the healthy stem cells of the donor.

There are two basic kinds of Transplants: autologous and allogeneic. In the autologous version, the patient's own stem cells are harvested during a period of strong remission when healthy stem cells predominate. The blood or marrow with the healthy stem cells is then frozen for later use when the disease has returned in force. In the allogeneic version, the healthy stem cells are provided by a donor whose tissue type closely matches that of the recipient. Susan will be having an allogeneic transplant.

In fact, there are two types of allogeneic transplants - the full or standard transplant (myeloablative transplant) and the so-called "mini-transplant" or "reduced intensity transplant" (non-myeloablative transplant). The standard transplant involves very high doses of chemotherapy and/or radiation in the conditioning phase (the week prior to the transplant), which is very hard on the recipient's system. The mini-transplant involves less intensive conditioning and is better tolerated by older patients (roughly 55 years old and up; Susan, like Jack Benny, is 39 . . . for the 22nd time). The standard transplant works by destroying the diseased bone marrow nearly completely, but with very significant stress on the recipient's system. The mini-transplant works by relying on the donor's immune cells, whose efficacy is bolstered by a drug protocol, to destroy the remaining cancer cells. Susan's medical team has determined that the mini-transplant is the most appropriate procedure for her.

The week or so prior to the actual transplant is referred to as the "conditioning phase" and is used to destroy as many of the cancer cells as possible as well as to suppress the patient's immune system to minimize rejection of the donor's cells. This is done via chemotherapy and/or full body irradiation, and can be very taxing. The actual transplant procedure is similar to a blood transfusion but takes several hours to accomplish.

In the immediate post-transplant period, the patient's immune system is severely compromised and he/she needs to be kept in a protected environment (first the hospital and then a kind of half-way house) and closely monitored. Within a month or so of the procedure, normal blood function is re-established to a degree sufficient to allow the patient to return home, but the environment needs to be very carefully managed to minimize infectious agents. Chronic Graft Versus Host Disease (GVHD - see below for "Risks") can be a significant risk for a year or more after the procedure.

RISKS

The conditioning procedure for an allogeneic stem cell transplant may produce a variety of unpleasant side effects, from mild to quite severe, but these are generally manageable and not considered life threatening. Because it involves a less rigorous conditioning, the "mini" version of the allogeneic transplant (the kind Susan is having) generally causes fewer and less difficult complications. However, there are still three major risks to consider with an allogeneic transplant :

1. Disease or infection.
The conditioning process essentially destroys the patient's immune system, leaving him or her virtually defenseless against disease or infection in the pre- and immediate post-transplant period. Therefore, it is extremely important that the patient's environment be carefully controlled to minimize contact with infectious agents. Measures include filtering the air in the room, requiring visitors to wear masks, ensuring frequent and thorough handwashing, eliminating raw foods (e.g., fruits and salads) from the diet, not allowing flowers or plants (which well-wishers might send) into the environment, and so forth. The medical team will also provide the patient with antibiotics and antimicrobial drugs as a preventive measure. It generally takes a month or so for the donor's stem cells to promote formation of enough blood and immune cells in the recipient for him or her to leave the protected environment.

2. Graft Versus Host Disease (GVHD)
The allogeneic transplant works largely through an effect called "graft versus tumor" (GVT), where the donor's lymphocytes identify the patient's cancer cells and destroy them. However, the donor's lymphocytes may also attack the patient's normal cells, which they might recognize as a foreign body and so a threat to be neutralized. When this happens, it is called Graft Versus Host Disease (GVHD), a complication that carries a definite mortality risk. The careful tissue matching that is done to ensure donor and recipient compatibility reduces the likelihood and potential severity of GVHD, but it cannot eliminate the risk.

The more complete the tissue matching (it is never 100%, except with identical twins), the healthier the recipient is going in, and the younger the recipient, the milder the case of GVHD is likely to be. Nevertheless, the majority of recipients will experience some degree of GVHD, despite the prophylactic drugs that the medical team administers.

GVHD occurs in two forms -- "acute" and/or "chronic." The terminology has nothing to do with the degree of severity, but rather refers to the timing. Acute GVHD occurs within the first three months, but its likelihood of occurrence diminishes somewhat with time. Chronic GVHD is what develops at some point after the period for the acute phase has passed. The risk for chronic continues for a year or more after the transplant procedure. A person who has developed and been cured of acute GVHD is still at risk for chronic, as is someone who has been symptom free even a year out.

3. Host Versus Graft Effect
Since the patient's immune system is not entirely destroyed by the conditioning regimen, it's possible for the remaining cells to reject the transplanted donor stem cells, in which case the transplant is unable to gain traction and do its work. Again, careful tissue matching between donor and recipient will reduce the likelihood of this effect to any worrisome degree, but some level of risk remains.
