Vitamin D and Cancer: No Easy Answers

The Journal of the American Medical Association published an article that this week that disappointed a lot of people. It's called "Addition of High-Dose Vitamin D₃ to Standard Treatment in Patients With Metastatic Colorectal Cancer: The SOLARIS Randomized Clinical Trial (Alliance A021703)." The hope was that taking high-dose vitamin D along with standard chemotherapy would improve outcomes in this specific group of colorectal cancer patients. Unfortunately, it did not improve Progression-Free Survival. 

The study looked at high-dose (8000 IU for two weeks, followed by 4000 IU daily) versus standard-dose (400 IU daily). There was a small PFS benefit for the high-dose group, but it wasn't statistically significant.

This isn't a study about Follicular Lymphoma, or any other kind of blood cancer, so it doesn't say anything directly about how vitamin D would affect those of us with FL. But studies of cancer and vitamin D always catch my eye because it's one of those interventions that people have asked me about fairly frequently over the years. There have been some tantalizing studies that get our hopes up. For example, in 2022, a study of Diffuse Large B Cell Lymphoma patients found that those with low Vitamin D levels had a lower response rate to CAR-T and a lower Overall Survival after 2 years than patients with normal vitamin D levels.  But that's not the same thing as saying vitamin D will improve outcomes if you already ave normal levels. Another study from 2019 found that Lymphoma patients who had higher sun exposure (and thus more opportunity for the body to naturally develop vitamin D) had a smaller risk of developing some kinds of Lymphoma, including FL. But they also found that getting vitamin D through food or supplements didn't have any effect. And then in 2018, there was a presentation at ASCO on a phase 3 clinical trial comparing FL patients who received Rituxan + vitamin D versus just Rituxan. I never saw results from the trial, which typically means it wasn't successful.

There are more. You can put "vitamin D" in the search box at the top of the blog to see more. But it's more of the same -- studies that show there might be some benefit maybe to some small population in some particular circumstance. I get these reminders every now and then that I need to step back and ask why I'm doing things and consider what I believe.

To be very clear -- I'm not saying you shouldn't take vitamin D. It has all kinds of health benefits. The National Institutes of Health have a nice comprehensive sheet that describes some of those benefits. 

But keep reading -- it also describes some of the problems that come from excessive vitamin D intake.

The point here is that it's worth knowing what your vitamin D levels are, and working with a doctor to figure out what that means for your own overall health. But I wouldn't expect it to cure your cancer. 

This is also a good time to remind you that I am not a medical doctor or a cancer biologist, and you shouldn't take medical advice from me. The best person to take medical advice from is your own doctor. They know you best, and they have the expertise to help you.

All of that said, I do take vitamin D every day. I tested low a few years ago, and my doctor recommended supplements. My vitamin D levels are normal now. I still take a fairly high dose every day, and that keeps me within normal range. In fact, it's at kind of the lower end of normal range, which suggests that my high dose is what I need. There's something happening in my body that keeps my levels low without the supplement. 

What is that thing that keeps my levels low? I have no idea, and I'm not going to worry about it. The very easy and fairly inexpensive intervention that my doctor recommended is doing its job. 

As I said, I like to have a reminder every now and then -- even a negative one -- that there are no easy answers, as much as we'd like there to be. The best we can do is stay informed, work with our doctors, and trust the excellent research that is being done.

 

Cancer Medicine Approvals in the US

The medical journal JAMA Oncology published a research letter a couple of days ago that I found really interesting. A "research letter" is a kind of informal discussion of research results, very different from the long articles that report of clinical trial results. But it provides some historical content for cancer research as a whole that should be very encouraging for all of us.

The article is called "Cancer Medicine Approvals in the US," and it looks at the circumstances surrounding the approvals of cancer treatments by the FDA for the last 20 years (from January 1, 2006 to December 31, 2025). The research focused on treatments for solid tumors, so there were no blood cancer treatments involved. There are also no pediatric treatments or generic drugs or biosimilars.

But even without the blood cancer treatments that would be most relevant to us, it still gives us a picture of the kinds of trends that have happened in the last 20 years. I think those same trends are probably true for those other treatments that aren't included in the data.

The researchers found that from 2006 to 2025, the FDA approved 385 different cancer treatments for solid tumors. Of those, 154 (40.0%) were for brand new treatments, and 231 (60.0%) were for new indications for approved treatments. For example, a treatment might have been approved for a first-line breast cancer treatment that was already approved for relapsed breast cancer. 

Another breakdown: of the 385 approvals, 105 (27.3%) were approved through the Accelerated Approval process. This means they were approved using data from a smaller phase 2 clinical trial, rather than a larger phase 3 trial. Accelerated Approvals are granted when a treatment meets a particular need that isn't being met by any other available treatment. That number is lower than I would have expected. It seems like there are lots of Accelerated Approvals these days for blood cancers, and they don't always work out well. So I feel a little better knowing that about three quarters of approvals are from the regular process. Accelerated Approvals often work out great, but they concern me sometimes. 

Another interesting bit of data: Traditional chemotherapy accounted for 40% of all approvals from 2006 to 2010. However, for the last 5 years, they have accounted for only 3.9% of approvals. This is not at all surprising. We can see it in blood cancers -- R-squared, CAR-T, bispecifics, monoclonal antibodies. All of them are proving to be good alternatives to traditional chemotherapy. They are more targeted, so they do less damage to non-cancer cells and have a different set of side effects. And even though the word "cure" was recently applied to R-CHOP, an immunochemotherapy combination, the excitement lately comes from those non-chemo options. 

Another interesting bit of information from the research is about endpoint markers. These are the data that ultimately proves whether a trial is a success or not. The best endpoint should be Overall Survival -- how many patients were still alive after 5 years or 10 years or whatever length of time they need to compare to. If a treatment keeps more people alive, that should be the measure of success, right?

It's more complicated than that. Only 102 of the 385 trials (26.5%) had Overall Survival as an endpoint. And that number is declining -- it went from 40% of trials from 2006 to 2010 to 18.7% from 2021 to 2025. Instead of Overall Survival, most trials used a "surrogate endpoint" -- a different statistic that shows "success." In blood cancers, especially in Follicular Lymphoma, the surrogate endpoint is often PFS -- Progression Free Survival, or the number of patients whose disease did not get worse over a period of time. This makes sense for FL -- if the Median Overall Survival is now 18-20 years for FL patients, it could take much too long for a treatment to be approved. No drug company is going to wait 20 years for the data they need to get approval. So while PFS isn't a perfect surrogate, it's good enough for FL.

For this research on solid tumor treatment approvals, PFS was the most common surrogate from 2006 to 2015 (60% of all trials). But from 2016 to 2025, the most common was Response Rate (46.7%). This strikes me as more problematic. A response to a treatment is great. But some responses last only for months. At least PFS typically goes on for a couple of years. Of course, I understand that not all PFS measures are long, and not all Response measures are short, and some for some cancers with few treatments available, any response is a big success. It's all more complex than these numbers suggest. But in my observation, it seems like PFS, and not Response Rate, is the primary endpoint for most new treatments, which is good.

One final bit of data comes from the way trials are constructed. Many consider the "gold standard" for clinical trials to be a randomized, two-arm controlled trial. This type of trial involves randomly splitting patients into two groups. One group gets the "standard of care" -- the treatment that is accepted as the best available at the time. This is the "control" group. The other group gets whatever new treatment is being tested. In this way, the researchers can guarantee that the two groups are the same and that a fair comparison is being made between the old and the new. The alternative is a "single arm" study. There is no direct comparison because there is only one group. The data from the trial is compared to another trial that took place in the past. There is no guarantee that the old and the new are the same. It's much easier to run a single-arm study like this, and they are more common in phase 2 trials than phase 3 trials.

This research found an increase in approvals based on single-arm trials -- 12.9% from 2006 to 2010, up to 40% from 2021 to 2025. 

The researchers conclusion says "Continued decline in the proportion of approvals based on overall survival, increase in response rate–based approvals, and underutilization of the accelerated approval pathway all reveal concerning trends." Interesting that they want to see more Accelerated Approvals. 

As I said, this research doesn't include blood cancers, but the trends that they see are pretty close to what I have observed over 18 years of paying attention to the research on FL. I'll admit that I have become kind of a Clinical Trial Nerd over that time, and I have some definite opinions about some things. But I will also remind you that I'm not a doctor or a cancer researcher, so keep that in mind.

The big lesson for me in all of this is that FL has a number of treatment options available to us. The whole reason I've become such a nerd is that there is so much research for me to read. So even when a treatment doesn't get approved, or gets pulled after approval, we still have other options. Don't ever lose sight of that. 

Stay well. More soon. 

EHA: Surovatamig + Rituxan

 I'm still sifting through some of the abstracts from ASCO and EHA from last week, and I found another one from EHA (the European Hematology Association's annual meeting): "SUROVATAMIG (AZD0486) PLUS RITUXIMAB IN PREVIOUSLY UNTREATED FOLLICULAR LYMPHOMA (FL): INITIAL SAFETY DATA FROM THE PHASE 3 SOUNDTRACK-F1 TRIAL."

(The EHA puts its titles in ALL CAPS.)

I don't know much about Surovatamig, which was previously known as AZD0486. I written about it only once before in the blog -- a description of a phase 1 trial that was reported on at the 2024 ASH conference.  Surovatamig is a bispecific, like Epcoritamab and Mosunetuzumab. It works by attaching itself to a cancerous B cell by grabbing on to the CD19 protein on the surface, and then also grabbing on to a T cell by the CD3 protein. In this way, it brings together the cancer cell and the immune cell that can eliminate it. 

The EHA presentation reports on results of a phase 3 trial called Soundtrack-F1. Let me say first of all that "Soundtrack" is a very cool name for a clinical trial. Maybe that's just because I love music so much.

Anyway, the study is looking at Surovatamig combined with Rituxan. It is a phase 3 study, with the goal of recruiting over 1000 Follicular Lymphoma patients who have not yet received teatment, though this presentation looks only at 43 of them. According to the U.S. government's clinical trials website, it has not begun recruiting trial participants in the U.S., which might be why I haven't heard much about it. Once this smaller trial is finished, the larger phase 3 trial will begin.

Still, even with only 43 patients, the researchers had some good things to present at EHA. The focus here is on safety rather than effectiveness -- reporting on the side effects experienced by the participants. The combination is interesting --  Surovatamig targets CD19, while Rituxan targets CD20. So there seems to be, at least in theory, that the two treatments would compliment each other well when used together. But any combination of treatments also means there is the possibility of doubling up the side effects.

For this study, the researchers looked at two different dose levels of Surovatamig, and divided the patients into two groups. It's very early in the trial, so median follow-up was about 6.3 months. The first group, which had a lower dose of Surovatamig, had a 95% response rate. The second group, with the higher dose, had a 100% response rate. At the time that they cut off the data to analyze it, 75% of patients in the lower dose group and 100% of patients in the higher dose group had no Minimal Residual Disease.

As for safety, 100% of patients had Treatment-Emergent Adverse Events (TEAEs), meaning side effects that develop after the treatment has been given. The most common were infusion-related reactions (36% in group 1 and 52% in group 2), mostly due to the Rituxan (not surprising to any of us who have had Rituxan). Other common side effects were fatigue (36% and 43%), muscle aches (36% and 38%) and low white blood cell counts (36% and 38%).

More serious side effects occurred in 18% of the lower dose group and 29% of the higher dose group. Cytokine release syndrome (CRS) occurred in 36% and 38% of patients and one instance of Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) occurred in each of the groups. 

The study was specifically designed as a "safety run-in," a smaller study to test for side effects before the larger study happens. It's interesting to me that this is happening in a phase 3 study; that kind of dose escalation (testing different doses to find the best combination of safety and effectiveness) usually happens much earlier. In this case, there wasn't much difference between the two doses in terms of safety, but there was a slightly better effectiveness with the higher dose, so that will be the recommended dose for the larger phase 3 trial.

The larger phase 3 trial will be a randomized two arm study. Half of the patients will receive the Surovatamig + Rituxan combination, and the other half will receive Immunochemotherapy (R-CVP + Rituxan maintenance, R-CHOP + Rituxan maintenance, or Bendamustine + R + Rituxan maintenance). 

There are a couple of takeaways for me. The first is that Bispecifics are clearly going to be in our future as FL patients. This kind of large study isn't messing around -- they're looking for full FDA approval. Lots of newer treatments try to get accelerated approval, and they do that with smaller phase 2 trials and aiming at Refractory/Relapsed disease. This trial has neither. That tells me that Bispecifics are fully mature.    Epcoritamab and Mosunetuzumab are pretty well accepted at this point.

The other thing that strikes me is the care that is being taken to focus on safety. As far as I can tell, there has not been a phase 1 or 2 trial for this combination, but that's probably because there are already known side effects for both of the treatments involved. Still, with so much already known about other Bispecifics, it's a help the the researchers to know what to look for in this type of treatment.

As always, looking at this kind of research being presented at medical conferences tells me that we have lots to look forward to. Not every treatment in a trial will ultimately be approved. In fact, less tan 10% will likely be. But there is still lots being tested, and lots of good stuff coming.

 

MGUS

If that title is confusing, don't worry -- I'll explain. I want to talk a little bit more about what happened at my last appointment with my oncologist.

I wrote about my appointment a few minutes after I got home, so I was still kind of processing it all. Let me go back about 8 months or so.

During my annual physical in the fall (with my general practitioner, not my oncologist), most of my blood work was fine. But my protein level was a little bit high. That number is really general -- there are lots of potential proteins in the blood. The Gen Prac ordered another blood test to see if it was some kind of one-time thing. 

The second blood test showed the same thing. The general test didn't say much, but the Gen Prac said it was somethng we should keep testing for to keep an eye on. At this point, I was getting close to my January oncologist appointment. I mentioned it to him (the Gen Prac and the Oncologist are not on the same Electronic Records system, so he didn't see the blood test results easily). The Onc looked through the test results and ordered some additional tests on the blood test I had done for him earlier that day.  The results came back the same.

So the oncologist ordered some additional, more sensitive tests to see what exactly was happening with the excess protein in my blood.  

At this point, he kind of repeated what the Gen Prac said -- excess protein like this can be a sign of several conditions, including blood cancers. It sounded very general and non-committal to me, given how detailed our discussions usually are. But I also was not in any mood to ask what it all meant, so I let it go.

But he did give it a name -- MGUS, meaning Monoclonal Gammopathy of Unknown Significance. (And if you are a fan of the move The Princess Bride, and that immediately reminded you of ROUS -- Rodents of Unusual Size -- then you and I have something in common.) 

MGUS, as he explained, occurs in about 5% of people over 50. There is about a 20% chance of it turning into something else within 20 years. He told me not to worry about it. We will be actively monitoring for it.

Fast forward to last week. I did a blood test for my Gen Prac a few weeks ago, and the protein level was fairly stable -- a tiny increase. She wrote a message in my Electronic Records about my cholesterol looking good. No mention of the proteins. I took that as a good sign.

The Oncologist did the same general protein level test, and then the more sensitive one. Another increase.

This time he was less non-committal. "So I'm now treating you for two blood disorders -- Follicular Lymphoma and MGUS. It's possible that the MGUS could turn into Multiple Myeloma. We will continue to monitor it and treat it if it becomes necessary."

This wasn't a shock. I've known about this for 6 months. It's not like Lympho Bob isn't going to hear something like that and not start doing research.

But it was still a little bit of a punch to the gut. I put it out of my mind, mostly, but a few days later, my wife and I were on a long car trip to see our son, and it kept creeping into my head.

It brought up a lot of old feelings, things I haven't really felt much in 18 years. The fear never really goes away. It's always just under the surface, bubbling up a little bit when it gets triggered. But this wasn't bubbling up. This was a small gush. It subsided eventually, and when my wife and I had another 4 hour drive on the way home, we talked about it. She had the same feelings return when the Oncologist started to talk about it. 

It helps to try to step back and look at things rationally. And that's not always easy, I know very well. But I did a little more research. The protein levels are indeed high. A normal range is something like 3 to 8 (I'm not even going to look up what the actual range is). Six months ago, mine was something like 8.7. This time it was something like 8.9. Patients with Multiple Myeloma can have levels in the hundreds or even thousands. I'm not there yet.

The more sensitive test of the protein showed that it was the type that leads to the least aggressive problems, if any problems do occur. So that's good news. 

Another potential problem is damage to the kidneys, which have to work harder to eliminate all of that excess protein. The Oncologist had me do a urine test. I got the results back last week. His nurse left a voice mail message saying the Onclogist thought "everything looked good."

So I'm relaxing a little bit now. No immediate danger.  

But it's amazing how much the body remembers, how that same feeling in my stomach returns, how a bit of electricity and heat rises from chest, up my shoulders, into my ears. That fear. It knows its path. It knows how to return. It's ready.

As I have said many times before, I think sharing our stories is one of the most important things we can do. It helps us. It puts the fear into words. That's an important step in dealing with things. Words can be dealt with. Feelings stay where they are and fester. 

But telling our stories helps each other, too. I don't know how many times I've been on both sides -- the teller and the listener -- and realizing that two people sharing the same experience make us both feel a little less alone. Our stories help others realize that there is someone else out there who has felt as we felt. That helps.

And I hope this has helped. It's OK to feel that fear every now and then. And it's more than OK to put it into words and share it. 

Stay well, and keep sharing. 

 

NCCN Guidelines

It's been a while -- I don't like to go more than a week without posting. I've been busy, traveling to see some family and hosting other family members. Exhausting but fun. I wouldn't have it any other way.

But it means I'm behind on reading about Follicular Lymphoma. So I'll do my best with this one (and also mention that I'll be hosting and traveling for another week or more, so expect another delay).

As I look through all of the links that I have been collecting, the one that stands out is a video from The American Journal of Managed Care's website. It's from a series of interviews with Dr. Ryan Haumschild, Dr. Christina Poh, and Dr. Tara Graff. In the series of videos, he provides some insight into newer approvals for Follicular Lymphoma treatment. If you've been reading the blog for a while, you know I like this kind of thing, which is fairly common on oncology websites. It gives an expert a chance to tell us where we are -- a nice overview of what is happening.

The series includes nine videos, but it is video number 7 that intrigues me: "NCCN Guidelines in Focus: Key Updates for Follicular Lymphoma and Their Impact on Formulary Decisions."

The NCCN is the National Comprehensive Cancer Network, a group of 34 cancer centers that work together to produce a series of guidelines for doctors to help them make treatment decisions for many different cancers. The guides are based on current research about the best order to use different treatments. I'd link to the FL guide, but you need to sign in to read them. I can occasionally get to a copy, so I've seen what they look like.

The NCCN Guide for FL are interesting because they provide so many options. There are probably cancers that have guidelines that say "If a patient is diagnosed with stage 3 of this cancer, then treat them with X." Pretty straightforward. Of course, FL isn't like that. There are a bunch of options at every stage. In some ways, that's good -- we have lots of options. In other ways, it would be really nice to have a straight path with one option because that one option works so well.

What intrigues me about NCCN guidelines is how they are used. As I have mentioned before, in my 18 years with FL, I have seen five different oncologists. Three were Lymphoma specialists, doing research on FL and other Lymphomas. The other two were generalists, treating blood cancer patients, but also patients with breast, colon, and other cancers. Those generalists are the ones that seem to rely most heavily on the guidelines, which makes sense. After I stopped seeing one of those generalists, I found a copy of the NCCN guidelines and kind of traced our conversations through the guide. For example, he really wanted me to have a PET scan, even though there was no indication that my disease was progressing. But the NCCN guidelines said that someone in my position can have one every year, so it was OK. Now "can" is not the same as "should." I didn't get the scan, but I did get some insight into how he made his decisions. I also got a new oncologist soon after that. 

So the discussion of the updates to the NCCN guidelines was especially interesting to me. It's a short video -- the main update was that Tafasitimab + R-Squared is now in the guidelines. This combination was approved just over a year ago by the FDA, though honestly, I haven't heard much about it since then. Most of the buzz since then has been about Epcoritamab, the bispecific that was recently approved by the EU in combination with R-Squared. (Dr. Haumschild expects this combination to be approved and added to the guidelines soon.)

I liked his insight into why all of this is important. As more treatments are added to the guidelines, they are likely to be used more. And as they are used, more "real word" data is collected on how effective and safe they are outside of clinical trials. And as more data is collected, we get a better sense of which treatments are appropriate for which patients. The NCCN guidelines are based on just that kind of data.

But data doesn't tell the whole story. Oncologists are human, and have their habits and their opinions, and "the best" isn't necessarily the treatment that the data would suggest.

I guess for me, the lesson for all of this is, first, be sure you are comfortable with your oncologist. Ask questions. Have discussions. In many ways, we are lucky to have a slow-growing cancer, and one of those ways is that we often have time to have those conversations before treatment is needed. The other lesson is, seek second opinions when you can. The guidelines offer lots of options, and it's nice to have a second set of eyes look through the records and make a suggestion. 

Things will slow down for me soon, I'm sure. I'll get back to reading more of this FL stuff then. 

 Take care.

 

Oncologist Appointment

I had a six month appointment with my oncologist today. Things look good (with some complications).

*******

As usual, I have had mixed feelings about my appointment. I feel fine, but it's still never fun to go t the cancer center.

For all of my appointments, I have a blood draw about 30 minutes before I meet with my oncologist. At the end of one appointment, I schedule the next one, and the blood draw, too. For some reason, I didn't do that last time. I booked my oncologist appointment, but not my blood draw. I'm not sure what I was thinking. I have a blood draw clinic near me that is run by the cancer center's network, so maybe I was thinking that I could save time by doing it a day before? I don't know -- that was six months ago. 

So when I got the reminder email a week ago, and the offer to pre-check-in on my Electronic Records portal, I saw that my blood draw wasn't scheduled. So I spend a week trying to figure out how to book the blood draw at the cancer center. It all worked out, but it seems like there is always something to add extra stress to the appointment. 

For this appointment, I asked my wife if she wanted to come with me. It's actually the first time in many years that she's come to an appointment. I almost always did appointments on Tuesdays, which was convenient for my work schedule, but not convenient for my wife's schedule. The after a while, she thought it might be bad luck to come, since my appointments had been going so well. It had been so long, she hadn't ever even met Dr. H, who has been my oncologist for a while. But she agreed to come with me.

It was nice to have her with me. I don't feel like I need the direct emotional support that I used to need, but it's still nice to have someone by your side. Plus, she sees and hears things that I don't because I'm so focused. And I don't mean things like the doctor's instructions. I mean things like overhearing someone else walking down the hall saying "I hate this place" ("You and me both, lady," was my wife's comment). Or noticing that the July 4th/World Cup decorations in the blood draw office looked like it was set up so people could take fun selfies with it, and then offering to take my picture, which she did:

 

For some reason, no one else at the cancer center blood draw office seemed interested in taking a fun holiday-themed photo. Go figure.

Anyway, my blood looked mostly good (more on that in a minute), and the physical exam was fine. No problems with the Follicular Lymphoma. 

But then there are the other problems.

For my last visit, Dr. H asked for some additional analysis for my blood because my total protein was too high. The analysis broke down the various proteins in the blood to see which one was causing problems. It turned out to be IgG, signalling a condition called MGUS -- Monoclonal Gammopathy of Unknown Significance. It's a benign condition that usually stays benign, though it can have some health consequences, the  most serious being the possibility of it leading to Multiple Myeloma, another blood cancer. For now, he says that there is maybe a 20% chance of that happening in the next 20 years. But the good news is, we are aware of it, and we can test it every 6 months to stay on top of it, so if it does turn into something else, we should be able to catch it early and deal with it. It was actually my General Practitioner who first noticed it, so my regular blood tests with her are also being analyzed for the same issue on top of the lipids, blood sugar, and everything else that she tests for. 

I don't particularly want to have to deal with Multiple Myeloma, if only because I would feel compelled to write about it. And then what am I supposed to do, start a new blog? "Myelo Bob"? I don't like it. Doesn't roll off the tongue the way "Lympho Bob" does. So I'm just not going to deal with it.

Dr. H says that it's unlikely that the MGUS is related to the FL, so if you're worried that this is something you or a loved one needs to pay attention to, you probably don't need to worry. I'm just special.

I hope all of you are getting good news at your own oncologist appointments, and that you are staying well. Take care of yourselves.

 

Donate to the Pan Mass Challenge

Hello everyone. I'm going to do something I very rarely do -- ask you for money.

It's not for me. It's for all of us, really. 

My brother is once again riding in the Pan-Mass Challenge -- a bike ride across Massachusetts to raise money for cancer research at the Dana Farber Cancer Institute in Boston.  

He's been doing this ride for 18 years, and he has raised over $88,000. Occasionally, he says "This year will be my last." It's a lot of work to train and ride on the day. Last year, he couldn't ride because he was injured, and it seemed like he was done. But here he is again. He just can't help himself. He knows how important this is. 

This is the email he sent out this year:

 

I hope you had a great July 4th Holiday weekend!  We're only 4 weeks out to this year's Pan Mass Challenge , and I'll be riding again for my 18th year.  

The PMC raises more money for charity than any other single event in the country, $1.125 billion since 1980 and $78 million in 2025 alone! This success is the result of a lot of people riding for, and caring about, a cure. And because every penny matters, 100 percent of your donation goes to Dana-Farber Cancer Institute. I've made a personal commitment to ride PMC 2026 and raise $4,000.00. I hope you can help me achieve this significant goal. To give online, you can use the following link to go to my personal fundraising site: http://www.pmc.org/profile/MM0386 Every donation brings us closer by the mile. Many thanks, Mike
