			<content:encoded><![CDATA[<p>It&#8217;s been nearly three weeks since my last post, making this just about five weeks that I&#8217;ve been out of the hospital now. Well, not exactly. We&#8217;ll get to that.</p>
<p>I&#8217;m still getting dizzy spells, but not nearly as many. Our best guess is that the intrathecal chemotherapy has messed with my body&#8217;s autonomic nervous system response. When you stand up from sitting your body automatically (and nearly instantaneously) recognizes that if it doesn&#8217;t constrict blood vessels in your legs, gravity will pull blood away from your brain and into your legs. This constriction keeps your brain getting oxygen and keeps you from passing out.</p>
<p>We think that response is (occasionally) not working quite right for me. In fact, a few weeks ago I was at the hospital getting checked out for some really bad muscle aches when I had one of these episodes. I&#8217;d been sitting, eating some take-out (Shultzy&#8217;s, mmm) that Jana picked up while we waited for a prescription to be filled. I got up and walked to the sink to wash my hands. Just as I grabbed paper towels to dry, my brain gave a brief signal that &#8220;hey, I&#8217;m not getting enough blood up here!&#8221; Before I had time to react, I started to lose consciousness.</p>
<p>Fortunately for us, the doctor that we&#8217;d seen chose this exact moment to peek in and see if we needed anything else. He and Jana were both right at hand when I needed to be helped to the floor. I, myself, don&#8217;t actually remember anything between grabbing the paper towels and being on the floor with a pillow under my head, surrounded by at least four nurses plus the doctor. I was out for at least a minute. Totally unresponsive. Jana couldn&#8217;t tell if I was breathing or not. It was interesting to learn that one side of my body started responding before the other. I spent the night in the hospital with monitoring equipment, and naturally nothing else exciting happened.</p>
<p>That&#8217;s what the bit in the beginning about the &#8220;five weeks since hospital&#8221; being not so exact was referencing.</p>
<p>Since then I&#8217;ve occasionally had spells of dizziness, but none nearly so epic. Until today.</p>
<p>We went to meet my new Group Health oncologist, and during the initial vital signs check my BP clocked in at 84/6o-something. 84! After sitting down for awhile chatting with the doctor, the nurse had me move from my chair to the exam bed. I didn&#8217;t take the normal precautions of standing and waiting in place, opting to move right away to the bed. I sat down, a wave of light-headedness hit me, and I was out. Apparently my eyes rolled up in the back of my head and my breathing sounded really labored. My arms were shaking like I was frustrated at something, and I wasn&#8217;t responding verbally.</p>
<p>We gave the staff quite a scare! They hooked me up to some IV hydration for an hour, and nothing else exciting happened the rest of the visit.</p>
<p>We&#8217;re all thinking that my low BP was related to not doing a good job the previous day of staying hydrated. On the way home we grabbed a ton of soda and juices that I can drink along with water to redouble my hydration efforts.</p>
<p>The best guess of everyone, after scans and consultations and talking talking talking, is that the occasional autonomic nervous system lack of response is a toxicity from one or more of the treatments I&#8217;ve had. The most likely suspect is the intrathecal chemotherapy that we&#8217;re using to try and keep my CSF cancer-free. But even for the neuro-oncologist we&#8217;ve been seeing, this isn&#8217;t a side-effect he recognizes from other patients. And we don&#8217;t want to stop the therapy. But the question remains: will continuing it make this worse?</p>
<p>It&#8217;s stressful dealing with these dizzy spells, and its stressful to think about reducing the amount of therapy we do. Fortunately, my blood pressure can accomodate some stress right now.</p>

			<content:encoded><![CDATA[<p>Hey there, long time no see! The last month has been a roller-coaster, full of ups and downs. In that order.</p>
<p><em>This is going to be really long. Check with your stomach first: is it growling? Grab a snack before starting to read. I care about your comfort!</em></p>
<p>At the beginning of December we did a bunch of testing; a PET scan, CT scans, a lumbar puncture, blood tests. All came back clean. <em>Complete remission!</em> The next steps were to come back in a few months for a CT scan and blood tests. Vigilance-mode.</p>
<p>And so we prepared to depart on our &#8220;Victory Lap&#8221; trip to Europe. Paris, the French countryside, Luxembourg, Belgium, and Amsterdam. 13 days, all told. Delicious adventure, beginning on Thursday the 10th.</p>
<p>On the Monday prior I felt absolutely great; my energy level was high, I got a ton of work accomplished and cleaned up the house like crazy.</p>
<p>On Tuesday we met with Dr Norman for the official all-clear. I had a little bit of pain near my ears that reminded me of the fun times I shared with Bell&#8217;s Palsy.</p>
<p>On Wednesday the pain was around just a little bit. It turns out that the &#8220;little bits&#8221; of pain were the tip of an iceberg. Wednesday night I found out the full size of the pain iceberg. I&#8217;d describe it as incredibly sharp <em>and</em> burning. Like a well-honed fireplace poker. It had me curled up in bed whining, and Jana calling the consulting nurse line.</p>
<p>They sounded like they thought it was ear-related, like water or infection. They recommended applying the Fentanyl patch that I&#8217;d been prescribed by Dr Norman after complaining of similar pain in late November. The patch delivers a continuous stream of opiate painkiller into the bloodstream after an initial 8-hour soaking-in period. By applying the patch at night we would know by morning if I would tolerate it for the flight.</p>
<p>The first noticeable sign that the patch was in effect was my inability to keep food down the next morning. My body isn&#8217;t used to handling continuous or large amounts of opiate painkillers, and it didn&#8217;t react well.</p>
<p>The second noticeable sign was that I had some big problems staying awake. Every 30-60 minutes I would start to doze off. This made the flight itself largely indistinct in my memory. I brought along books and movies, and there was plentiful in-flight entertainment, but I consumed none of them. Instead I slept, and was excited when I was able to keep down the offered orange juice. Small victories!</p>
<p>We arrived in Paris, watched someone get scammed and pick-pocketed on the train, and eventually found our hotel. It was quaint and cozy, which is a pleasant way of saying old and small. The view from the window was the best part of the room. We looked out east upon part of the Latin Quarter.</p>
<p><a href="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_14051.jpg"><img class="aligncenter size-medium wp-image-177" title="View from Paris Hotel" src="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_14051-225x300.jpg" alt="" width="225" height="300" /></a></p>
<p>A 15-second walk from the building was a crepe stand, and I was able to eat half of a chocolate crepe before I felt like I needed to stop. That patch made it hard to dive in and enjoy the food!</p>
<p>Not long after we arrived I collided with the iceberg of pain again. Curled up whining on the uncomfortable bed, the patch didn&#8217;t take away the pain. It just made me fall asleep every once and awhile. I slept in 30-60 minute bursts.</p>
<p>This continued for every night that we were in Paris. And also during some parts of the days. The patch eventually wore off, and I was able to eat food again, but the pain remained and continued to mess with my sleeping.</p>
<p>There was one day when we got out to do a little bit of sightseeing at Jardin de Plant and the Evolution Museum. Then there was another <em>great</em> day when we walked to the <a href="http://en.wikipedia.org/wiki/Basilique_du_Sacré-Cœur,_Paris">Basilique du Sacré-Cœur</a>, <a href="http://en.wikipedia.org/wiki/Notre_Dame_de_Paris">Notre Dame de Paris</a>, and <a href="http://en.wikipedia.org/wiki/Musée_d%27Orsay">Musée d&#8217;Orsay</a>. I was really glad we got to have those together.</p>
<p><a href="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1419.jpg"><img class="aligncenter size-medium wp-image-180" title="From Sacre Cour" src="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1419-300x224.jpg" alt="" width="300" height="224" /></a></p>
<p>Eventually we checked out of the hotel early to go to the <a href="http://en.wikipedia.org/wiki/Hôtel-Dieu_de_Paris">Hospital Hôtel-Dieu</a>, and the hotel graciously didn&#8217;t charge us for the rest of our reservation. After a 20-minute wait the doctor in the emergency room took a look in my ear and said the pain was due to flying while having an ear infection. He prescribed an antibiotic and a codeine painkiller and sent me on my way.</p>
<p>We decided that recovering from something so painful would be best done in a relaxed and comfortable setting, and Paris didn&#8217;t seem like the place to find it. We contacted some family friends that live in London and they very generously offered to host us while I attempted to recover. We took metro to Paris Nord station and hopped on the Eurostar train to London. Once we were underway we realized: if the pressure change from the flight caused the pain, would the pressure changes in the Channel Tunnel do the same? Fortunately they did not.</p>
<p><a href="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1432.jpg"><img class="aligncenter size-medium wp-image-181" title="View from House in London" src="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1432-300x225.jpg" alt="" width="300" height="225" /></a></p>
<p>In London we were treated to delicious home-cooked meals and gracious hospitality. But the pain remained. Near the end of the antibiotics course I could note no improvement. And the prescribed painkillers served to make me drowsy, but did nothing to melt the iceberg. So we went to the emergency room at the <a href="http://en.wikipedia.org/wiki/Chelsea_and_Westminster_Hospital">Chelsea and Westminster Hospital</a>. After a 3-hour wait the doctor looked in my ears, looked for physical signs of meningitis, and then said that he thought there was some inflammation or water behind my ears that was causing the pain. He referred us to the emergency room at <a href="http://en.wikipedia.org/wiki/Charing_Cross_Hospital">Charing Cross Hospital</a>, specifically to see an on-call <a href="http://en.wikipedia.org/wiki/Otolaryngology">ENT</a> doctor who would provide some better expert opinion.</p>
<p>This other doctor looked in my ears and said that she believed the pain was because I had water behind my ears and a bunch of congestion. She felt that the two were combining to create pressure that in-turn caused the pain. She recommended decongestants and not flying until it was improved. She noticed that my left eyelid was drooping a bit, but I felt that my right eyelid was probably under some light <a href="http://health.tommusic.net/2009/09/a-complication-draws-near/">Bell&#8217;s Palsy effect</a> (opening too much) and that my left eye was just compensating.</p>
<p>But the decongestants didn&#8217;t help. Even when I was all cleared up, the pain remained. Maybe we just needed to give it some time. We decided it was time to return to tourist mode, so we bid farewell to our hosts and headed to a <a href="http://www.thegrandattrafalgarsquare.com/">hotel</a> in Trafalgar Square. We got out for a short walk and a nice Italian lunch, but I spent the rest of the time miserable in the room.</p>
<p>I started to notice that my <a href="http://en.wikipedia.org/wiki/Ptosis_(eyelid)">left eyelid was drooping</a> even more, and my vision was a bit affected. Blurry. Sometimes <a href="http://en.wikipedia.org/wiki/Diplopia">double-vision</a>, like when you go cross-eyed. And my legs and arms were weaker. And <a href="http://en.wikipedia.org/wiki/Disphagia">swallowing food was a little more difficult</a>; like when you eat something really dry and it feels like it gets stopped-up in your throat.</p>
<p>And these things got worse. It was getting hard to put a glove on my right hand, because the two middle fingers were pretty much completely limp. My right tricep was getting less and less responsive.</p>
<p><a href="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1438.jpg"><img class="aligncenter size-medium wp-image-183" title="Ticket at St Thomas Hospital" src="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1438-225x300.jpg" alt="" width="225" height="300" /></a></p>
<p>New symptoms; it was time to go to the hospital again. This time we were closest to <a href="http://en.wikipedia.org/wiki/Guy%27s_Hospital">Guy&#8217;s Hospital</a>. After a 30-minute wait we were taken a bed in the Major Treatment room, where we waited for another 30-minutes before seeing our first doctor. She did a series of tests, including a bunch of physical tests of neurological symptoms: testing reflexes, coordination, muscle strength, eye movement. There were definitely some problems. We shared with her the research that I had done online, suggesting the possibility of an auto-immune disorder called <a href="http://en.wikipedia.org/wiki/Myasthenia_gravis">Myasthenia Gravis</a>. She noted that it was definitely on her differential diagnosis list, but that the testing didn&#8217;t reveal the fatigue that is common in cases of MG.</p>
<p>She eventually deferred to a colleague, perhaps at the end of her shift, and he performed a similar battery of tests. His conclusion was that he&#8217;s not sure of the diagnosis, and would like me to stay in the hospital overnight to see a different doctor in the morning during rounds.</p>
<p>They put us up in the Victoria ward with a nice view across the Thames of part of the Parliament. Nice!</p>
<p>During rounds the head-honcho doctor did a truncated neurological exam and then chatted with us for a bit; his conclusion was that for them to diagnose me, we&#8217;d need lots more testing and scans. His recommendation was that we abort our trip and head home to the doctors already familiar with my case.</p>
<p>To the airport! Our hosts from earlier picked us up and took us to Heathrow. Such awesome folks. We owe them a tremendous debt of gratitude.</p>
<p>We spent a bunch of time on the phone trying to get ahold of KLM who had a direct flight to Seattle that we hadn&#8217;t been able to book online. After 30-40 minutes of being on hold, we gave up and decided we&#8217;d book at the airport. Um yeah, about that&#8230;</p>
<p>We were dropped off in terminal 3, and KLM was actually in terminal 4. An elevator, long hallway, another elevator, and we were at the inter-terminal train system. 26 minutes until the train to terminal 4! Maybe Virgin Atlantic has something, they&#8217;re here in terminal 3. We head back up the elevator, long hallway, and elevator. We learn that Virgin&#8217;s flights to the West Coast have all left for the day, but there might be something to NYC left. We head to the counter and wait. Each line only had 3 people ahead of us, but I don&#8217;t think either line moved. Time was up: if we wanted to catch the train to visit KLM, who we knew had a flight, we had to give up on Virgin. And so we did, making it to the train <em>just</em> before it departed.</p>
<p>Elevator, hallway, elevator.</p>
<p>We found the ticket purchase desk for KLM/Air France, and the line was epic. 3 hours epic. The flight left in an hour and a half, there&#8217;s no way that would work. And so I turned on international data roaming on my phone and used the <a href="http://www.kayak.com">Kayak</a> app to find out that British Airways had a flight to Vegas leaving in a few hours. BA, however, was in terminal 5.</p>
<p>Elevator, hallway, elevator. Train back to terminal 3, train connecting to terminal 5.</p>
<p>While waiting for the train I decided to get some backup. I texted my Dad, who was aware of our plans for a quick escape and was listening for pings. It was 2 or 3 AM in the States and he and my Mom woke up to help. The plan was that they would try and book tickets for the BA flight online, quick and easy.</p>
<p>They tried and ran into some &#8220;Transaction Failed, return to the Home Page&#8221; speed bumps. We elevator, hallway, elevatored it up to terminal 5 and found BA&#8217;s line to be no less epic than KLM. There had been a lot of snow-related flight cancellations in France and on the US East Coast, so throngs of travelers were standing in line to re-book. Jana got in line and I found a place to sit. I was feeling really tired and my legs really weak. Staying on the line with my parents, they were eventually able to coax the BA site into buying economy fare tickets for the Vegas flight. I found Jana in the line and we escaped to the check-in computers. We were already in the system. Slick. It was just too close to departure to get seat assignments, so we had to visit the customer service desk where we find that we were &#8220;brilliantly&#8221; automatically upgraded to &#8220;economy plus&#8221;. It&#8217;s just line normal economy, but with better legroom. We&#8217;ll take it!</p>
<p>I foolishly ordered ribs and fries at a restaurant at the airport. At this point I could hardly swallow a fruit smoothie! It was frustrating to have food that I know to be tasty sitting in front of me, and not being able to eat it.</p>
<p>We got some bad news from my folks: the flight to Vegas gets in too late for us to make the connection to Seattle, so we&#8217;ll be staying overnight at a hotel real close to the airport. They took care of booking the hotel and the flight to Seattle in the morning. Two angels, they are.</p>
<p>We get back to Seattle and head straight to the hospital. They give me some IV Dilaudid and that provides my first sweet relief from the pain. Oh man, it was like putting on a warm blanket and removing that hot poker from my head at the same time. We did an MRI and a CT scan, and found out that the pain was due to a huge amount of inflammation of my cranial nerves. And the diagnosis for why there was inflammation?</p>
<p>There was lymphoma stowed away in my brain, and it had finally multiplied enough to cause obvious problems.</p>
<p>Recovery and treatment was going to require some time in the hospital. <a href="https://www.virginiamason.org/home/homepage.cfm">Virginia Mason</a> to be specific.</p>
<p><a href="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1445.jpg"><img class="aligncenter size-medium wp-image-184" title="View from Virginia Mason Room 1576" src="http://health.tommusic.net/wp-content/uploads/2010/01/IMG_1445-300x224.jpg" alt="" width="300" height="224" /></a></p>
<p>They set me up with Dexamethasone to reduce the inflammation and get started fighting the lymphoma, and more Dialaudid to keep me above the pain. It worked. After a few days I was already seeing my neurological symptoms improving. My eyelid got better, and swallowing improved to the point where I could eat Cream of Potato soup. The double-vision overlapped more.</p>
<p>One thing that was annoying was the amazing love for <a href="http://en.wikipedia.org/wiki/Heparin">Heparin</a> shots. Hospital policy is that patients receive shots of Heparin a few times a day to keep them from developing DVT to inactivity. The shots go in your belly, and man do they sting! Even now, I have faint red circles from the shots. Protip: <em>you can decline the shots. You just gotta be assertive.</em></p>
<p>Dr Feldman, the on-call oncologist for the first week had worked previously with a neuro-oncologist (Dr Taylor) that was based at Virgin Mason. That was a slick connection. She looked at my MRIs and was able to read them with the eye of a brain specialist. Together they put together a recommendation for two different chemotherapy series to be run at the same time.</p>
<p>The first is <a href="http://www.rxlist.com/depocyt-drug.htm">Depocyt</a>, delivered <a href="http://en.wikipedia.org/wiki/Intrathecal">intrathecally</a>, which is built as a sort of time-release capsule of the chemotherapy agent <a href="http://en.wikipedia.org/wiki/Cytarabine">Cytarabine</a>. The second is a high-dose <a href="http://en.wikipedia.org/wiki/Methotrexate#In_cancer_chemotherapy">Methotrexate</a>, administered through my chest port, affecting the entire body (including penetrating the blood-brain barrier). The high-dose Methotrexate course requires a hospital stay at the start of each cycle, because they want to closely manage my recovery after administering the deadly dose of poison. Once my body processes enough of it that the level in my blood is no longer dangerously high, I&#8217;m free to go home until the next round.</p>
<p>This time the cycle length is two weeks (instead of three), and the plan is for at least 4 cycles. We&#8217;ll do some measurement (via MRI) after the second round, and test <a href="http://en.wikipedia.org/wiki/Cerebrospinal_fluid">CSF</a> during each intrathecal infusion.</p>
<p>Now, two weeks after my first round of chemotherapy (which we started on Christmas Day), I&#8217;d say that I&#8217;ve recovered about 80% of what I lost due to the inflammation. My eye is 95%, swallowing is 100%, right-hand ability is 90%, right tricep is back to about 50% of strength (better than 0%!), and the rest of my arms and legs are still at about 70% of strength. If I was to assign numbers to these sorts of things.</p>
<p>I haven&#8217;t collided again with the iceberg of pain since getting out of the hospital, but every once and awhile I spy part of the tip of it in the distance.</p>
<p>I wait in fear to see how my phone bill with all of the international roaming adds up. We had a few hours worth of calling during the &#8220;escape&#8221; stage of the trip, and that&#8217;s not going to be cheap.</p>
<p>And so we&#8217;re back to the &#8220;endure&#8221; stage. Our Victory Lap was premature, but we didn&#8217;t know that at the time. The next few months will be difficult, but it&#8217;s a difficult that we know. A <em>difficult</em> that is <em>imperative</em>.</p>
<p>There&#8217;s cancer in my brain. We have experts we trust that have advised us on a course of treatment. There&#8217;s no choice of &#8220;do we&#8221; or &#8220;don&#8217;t we&#8221;, only of how well we do it.</p>
<p>&#8220;Come on! Are you a <em>can</em>cer patient or a <em>can&#8217;t</em>cer patient?&#8221; Sorry. <img src='http://health.tommusic.net/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>To be ready to collect stem cells the <a href="http://en.wikipedia.org/wiki/CD34">CD34+</a> <a href="http://en.wikipedia.org/wiki/Pluripotential_hemopoietic_stem_cell">cell</a> concentration in one&#8217;s blood is supposed to be above 8 * 10^6/ml. If the concentration is too low, collecting a viable transplant amount will take too many sessions. And at 4-5 hours a session, fewer is better!</p>
<p>Back on the 9th (a Monday) my CD34+ concentration was 1.01. My white blood cell count was nice and high though, so we made plans to give my blood until Thursday to recover from chemo. We&#8217;d test again with the intention to collect on Friday.</p>
<p>On Thursday I was at the threshold; my blood was ready to rock. Friday morning we went to the SCCA&#8217;s <a href="http://en.wikipedia.org/wiki/Apheresis">apheresis</a> unit for a long day. They tested my CD34 concentration again: 40.32. More than ready. Ripe for the picking!</p>
<p>But first: <a href="http://en.wikipedia.org/wiki/Lidocaine/prilocaine">EMLA cream</a>! I applied it to the areas where I expected they might place the needles and it did a pretty good job of numbing the skin. If you ever use it, be sure to cover it with something like saran wrap or <a href="http://en.wikipedia.org/wiki/Tegaderm">Tegaderm</a>. And give it 30 minutes to an hour to soak in.</p>
<p>The process required placing two needles: one that would flow blood out of my body into the apheresis machine, and one that would flow back in. At any given time the machine has about a cup of blood in it, and during the 5 hours they cycled 6 times my body&#8217;s total blood supply through the filter.</p>
<p>The machine separates the blood into three different layers based upon weight: plasma, red blood cells, and the <a href="http://en.wikipedia.org/wiki/Buffy_coat">Buffy coat</a>. The Buffy coat contains a bunch of different types of cells, one of which is the delicious <a href="http://en.wikipedia.org/wiki/Pluripotential_hemopoietic_stem_cell">pluripotential hemopoietic stem cells</a> that we&#8217;re wanting to collect. Unfortunately, since the Buffy coat also has other types of cells, they don&#8217;t know how many HSCs have been collected in each batch until they run some tests after it has been collected. You don&#8217;t know if you&#8217;ll need to come back again until a couple hours after each day of collection.</p>
<p>My collection took a little longer than normal since they were using my veins instead of a <a href="http://en.wikipedia.org/wiki/Central_venous_catheter">central venous catheter</a> or (&#8220;central line&#8221;). A central line can handle higher flow rates because it&#8217;s a tap into a large vein; arm veins aren&#8217;t as beefy. Still, mine let us go to about 80% of the norm for a central line. I was willing to endure the slightly longer collection in exchange for one fewer surgery. Well, two fewer; I would&#8217;ve had to have another surgery to remove it!</p>
<p>For a solidly viable transplant they want to collect at least 5 x 10^6/kg HSCs, which they say usually takes between 1 and 4 days. We finished up my collection, and Jana and I headed out for a quick dinner before returning to Group Health for our evening appointment. If I was going to need to return for another day of collection, I was told I should get a two-unit transfusion to boost my red blood cell and platelet counts. It would likely take a couple of hours, but I&#8217;d feel better from it.</p>
<p>We got to Group Health early and hung out in the waiting room with our cell phones nearby. The SCCA apheresis folks were to call us once they got word on how much we&#8217;d collected. We waited, waited, and waited some more. I eventually went to the desk and checked in; just as they were showing me to my room for the transfusion I got the call: we needed at least 5.0, we collected 9.6!</p>
<p>And that&#8217;s how we collected nearly double the necessary amount of HSCs in a single session without needing to place a central line.</p>
