Shorter radiation is better

Shorter radiation is better

Sometimes editing takes out all the important information. This took  a lot of digging to find out what the hell it was talking about.

I first came across this article which says higher dose shorter radiation is better that the traditional radiation given to breast cancer patients. This makes sense because the damage from radiation is cumulative meaning that it gets worse and worse after each treatment. Other side effects such as fatigue are also lessened from the shorter course of treatment.

Well that is nice to know but how much shorter is it? I couldn't tell but did go find the referenced article, Differences in the Acute Toxic Effects of Breast Radiotherapy by Fractionation Schedule: Comparative Analysis of Physician-Assessed and Patient-Reported Outcomes in a Large Multicenter Cohort, on JAMA Oncology. You got that?

How's this instead?

"Randomized trials have established that hypofractionated regimens of radiotherapy to the whole breast can provide long-term disease control that is equivalent to the excellent outcomes of more protracted conventional fractionation schedules in selected patients undergoing lumpectomy for breast cancer. Hypofractionation might also result in lower rates of late toxic effects than conventional fractionation. Although the American Society for Radiation Oncology has issued consensus guidelines to identify patients in whom hypofractionation is appropriate and endorsed consideration of hypofractionation in its Choosing Wisely campaign, uptake of hypofractionated regimens has demonstrated considerable variability worldwide and has been relatively slow within the United States."

Okay, what if I tell you this:

"Traditionally, women undergoing lumpectomy for breast cancer were treated with 5-6 weeks of daily radiation after surgery. "Hypofractionated" regimens are shorter courses of radiation, in which a slightly larger dose of radiation is given per day, allowing radiation to be delivered in a shorter period of time, most commonly in 3-4 weeks."

Finally, I get to the truth and find that 2 weeks less, slightly higher dose radiation offers fewer side effects? Why couldn't they say that first?
Not a practical option

Not a practical option

Earlier this week, or maybe it was last week, I saw several articles on this new intraoperative radiation for breast cancer. This is when a radioactive probe is inserted into the breast during surgery and allows the patient to skip traditional radiation. Of course, they may still need chemotherapy and other treatments.

The first articles I saw touted its benefits. I was a bit pessimistic about this. I have heard about it and think it is approved in the US (but I am no doctor so don't think I know all about this). It is only for certain early stage breast cancers so it is not for everyone.

The reason for this hype is that it was just approved in the UK's NHS. And then I just saw this article about a UK doctor's thoughts on this:

"The treatment, given approval for NHS use in draft guidance by the National Institute for Health and Clinical Excellence, would benefit up to 36,000 people nationwide.

The technique, called intra-operative radiation, is suitable only for patients who have caught their cancer early..."

"...The initial price of the treatment is expensive, with each probe costing £500,000.

The procedure is performed during surgery.

Once the tumour is removed, a probe is inserted into the breast and delivers radiation to the site of the cancer for about half an hour."

That is when I fell off my chair. Am I understanding this correctly? Each probe costs  £500,000. Clearly it must mean the entire big instrument. Not just an individual probe. But I can't tell for sure based on how the article is written.

If its £500,000 for a single treatment, that is crazy. And if the machine costs £500,000, that's just damn expensive. Not a practical option in my opinion.
I used to be jealous

I used to be jealous

Back in 2007 when I had radiation for my breast cancer. I had to undergo the traditional radiation treatment which meant 37 visits spread over 7 weeks - five days a week that lasted FOREVER. I knew people online who were getting the short version and getting radiation for five days - brachytherapy - with two visits a day. I was jealous because I was (and still am) sick of going to the (damn) hospital.

I had asked at the time and was told by my radiation oncologist that they did not offer the shorter option nor did most hospitals in Boston at that time. A few years later I attended a conference where I learned they were starting to offer the shorter option as well as expanding their other services.

Now new research on women over sixty who had brachytherapy after a lumpectomy are more likely to have a mastectomy five years later. They were more likely to have treatment complications that resulted in the mastectomies.

ASTRO is considering new guidelines for who would most benefit from brachytherapy and cautionary and unsuitable criteria. The number one criteria seems to be that it is best for women over sixty.

Since I do not fit their criteria I am glad I did not get brachytherapy as it could have increased risk for mastectomy. I am not jealous any more.
