The second cycle

 
Two weeks ago, Asa had his second dose of chemotherapy. So far, the second cycle has been much easier than the first. We’ve managed to stay at home except for short visits to hospital, and we've largely succeeded in controlling Asa's discomfort. 

Part of the reason for this is that we’ve been giving him potassium supplements to head off hypokalaemia, whereas the first time around it was several days before we began using potassium. But a bigger reason is that the dosage of the most potent of the drugs he is on – Vincristine – has been halved.

Halving the dosage of this drug is a big deal, because our most immediate challenge is managing the side-effects of the chemo drugs.

In the first cycle that meant trying to distract him from pain.  This time it's mainly meant trying to get him to eat. 

Asa feeding Jed feeding Asa....  Oranges are the only food he's never refused.


Expecting that Asa might have difficulty feeding, we had a naso-gastric tube inserted just a couple of days after the second dose of chemo.  The tube is useful not only for topping him up with food when he’s not taking anything by mouth, but also for giving him anti-nausea medicines and potassium syrup (which can themselves be nauseating to swallow).

Thankfully, he has been breastfeeding well throughout.

In this way we’ve been able to get him through the rough first few days of the cycle, until his appetite starts to revive.

Blood counts

Next week, we'll learn whether the drugs have been working – whether the cancer is receding.  On Wednesday, the staff at the Retinoblastoma Service in London will examine Asa’s eyes, and assess how much the tumours have shrunk since he began chemo.

For the time being, the main indication we have of how the medicines are working is Asa's blood counts.  These give us an idea of how effectively the drugs are inhibiting the reproduction of fast-developing cells throughout his body (including the cancer). 

The blood components that are most important to keep track of are haemoglobin (red blood cells) and platelets. Haemoglobin carries oxygen to cells, and platelets help the blood to clot.  They’re important not only because they serve as an index of the drugs’ action, but also because if they fall below critical levels, one needs transfusion.

Platelet and haemoglobin counts for cycles 1 and 2 of chemotherapy. 
Cut off points for transfusion are 30 for platelets and 7 for Hb.


Yesterday Asa's haemoglobin levels dropped into the danger zone for the first time, and today he received blood transfusion at our local hospital. 

This is something we'd been hoping to avoid.  But, as with so many other choices we’ve had to make recently, transfusion is much better than the alternative – seeing him become more anaemic, and increasing the risk of spontaneous bleeding.

Who are you calling anaemic?

Asa hadn’t shown any of the lethargy that often accompanies anaemia.  In fact, even during the days when he wasn’t eating, he looked and behaved much like any other toddler, ebullient and energetic.

But it was a pinker, better perfused Asa who emerged from hospital this afternoon, with 200 ml more red blood cells in his system than before.

Taking a walk in the hospital corridor during transfusion
 
In the past week Asa began to stand by himself, and to walk confidently when his hands were being held. 

It’s a source of wonder to us that, despite all he’s going through, Asa should be developing as fast as he is. 

During a week-long stay in hospital last month, he began saying, “Dada”.  He claps his hands and applauds himself when he’s succeeded in stacking hoops onto a pole (one of his favourite games).  And his babbling becomes more florid and melodic each day.

All of this buoys us up, and keeps us optimistic.  

As my mum observed, in some ways it’s easier for those of us who are with Asa day to day than for those who aren’t, because we see the happy times as well as the sad ones.  Those happy moments are in large part what keep us going – them, and the love and support we receive from friends and family.

Many thanks to all who sent birthday wishes to Asa.  And to everyone who's reached out to us.

  1. Excellent update! I hope you're given good news on Wednesday. It's great to see such lovely photos of the family, and how wonderful that Asa's saying Dada ...I can only imagine how it will feel to be named aloud by our children. We pray for Asa and all of you each day. love, Caroline, James, Lily, & Mary

  3. It seems things are going as well as one can hope in this difficult situation. I love the pictures of your boy- he looks strong and spunky, and I think he is probably an inspiration to more people than just me. I hope things continue to go well.

  4. Thank you all. Asa's blood counts weren't high enough to go ahead with the exam and 3rd cycle of chemo this week, so they've been postponed til next week. I'll post again once we've got more info. In the meantime we're enjoying a pleasant lull. Love, Jed

Afterlife

Spring. Bulbs and buds burst into flower. Things come back to life.
Ayya's namesake Anne was born in Spring, in Nashville, Tennessee, on March 25th (also known as Lady Day, or the Annunciation), the day when people in Medieval Europe thought the world began.


What threads connect Anne to Ayya? What affinities, beyond a name, and a fraction of shared genetic material?
As a young woman, Anne lived in Africa for five years. She had just married a Frenchman, Jean-Paul, and accompanied him to Cameroon, where he was to work as a teacher in lieu of military service. She was a new mother at the time (she carried my cousin Miriam with her), and it was there that she gave birth to her second child, Eric.
One of my favourite works of anthropology is a study of infancy in West Africa. Among the Beng of Cote d’Ivoire, children are understood to come from the Afterlife. In their way of thinking, people’s spirits enter a sort of limbo when they die. When babies are born, they gain passage back into l…

Cataract / VI

At about 4 o’clock this afternoon, Asa came around after being under anaesthetic for a cataract operation. It was the first time he’d had surgery – indeed, anything but routine eye exams – for more than a year.
Selam and I felt more anxious than we’d expected to be about this operation. It brought back memories of difficult times. Times – there had been dozens of them – when we waited, with a mixture of fear and hope, for news of how the procedure had gone. There had been a few times when we’d felt we we were close to losing him – like that time when he was on second-line chemo, and I was in Congo, and Selam told me over the phone that his Hickman line was infected. Or that time, during the third course of chemotherapy, when he went into anaphylactic shock.
Compared to those occasions, this cataract operation was low-risk. And, thank goodness, it went smoothly.
As Asa gradually regained consciousness, he put his fingers to the plastic shield taped over his right eye to protect it. Sela…

Blind for a day

My mum likes to say that we learn about our bodies the way we learn about cars -- each time something goes wrong, you get acquainted with a new branch of mechanics.

As various treatments have been tried out on Asa, we've learned more and more about cancer and the eye.

The graph below summarises the treatments Asa's received these past 18 months.



Situations where retinoblastoma fails to respond to both primary and secondarychemo are rare, and even at one of the world's specialist treatment centres, a doctor might see such a case only once every few years.

 Support research on eye cancer here.
Right now we're in a place, therefore, where epidemiology and large trials have ceased to help much, and clinical judgment becomes very important.

As Dr Jenkinson -- the oncologist we met with in Birmingham -- said, "We're beyond the situation where there's a firm evidence base."

What's required then is very close attention to the details of the disease as it'…
