Congratulations friends!
I matched at my #1. In the interest of providing some anonymity on this account so I can continue to use it for the future, I'm not going to say where it is but I'm providing my overall trajectory and interview impressions for all the programs I interviewed at (11+my home program, which is not included below - no, I didn't match at my home program). I hope the full set of stats and interviews helps someone in the future, good luck!
48 applications, 12 interviews, 14 rejections, never heard from the other 22 programs. First invite was 7/27, last invite 9/5. The bulk of invites happened in the first two weeks of August. I wrote a few emails to the programs that I didn't hear back from asking about interviews but none of them worked, just FYI.
AMG, mid-tier academic residency, really bad board scores (200s in step 1 and 3), took a gap year to bolster research, significant research with 15+ abstracts/presentations/papers.
The following is my UNRANKED interview impressions in no set order (literally used a number random generator on my rank list and wrote them in order of the random generator).
Cornell — strong in liquid malignancies; they have separate subdivisions and dedicated faculty in leukemia, lymphoma, and myeloma. Used to require basic lab research for all fellows but they have moved away from it. Similarly, fellows used to be able to go over to MSK for electives or research but they're trying to cut down on it now the program has gotten stronger. Lots of access to clinical trials. Fellows' perception of the clinical training is mixed — seems to be really busy when on service. The fellows who are committed to research do really well coming out of the fellowship. Probably the best in NYC for liquid malignancies.
Sinai — a good mix of solids and liquids. the chief of the department is a GU oncologist from Harvard and he seems really committed to continuing to recruit strong faculty especially in solids to Sinai (traditionally Sinai is stronger in liquids). The hospital is well-off financially and the heme-onc division keeps expanding its footprint. The attached medical school has a school of public health for support in epi/outcomes research. Fellows were chill. Kind of disorganized interview day where you had to go between multiple different buildings to find your interviewers (and there was no guidance between the buildings).
UCSD — the fantastic location aside, overall with a great patient base and access to many different types of research. Fellows can do basic and translational research if needed at Scripps and Salk Institute. Despite the overall established-ness of the cancer center (which appears to be very adequately funded), they're still trying to grow their fellowship (both literally in terms of size and also in terms of supporting fellows to do more research). So far, it seems that most fellows who do research focus on basic/translational, and honestly there isn't much of it. A lot of fellows go into private practice. The PD is very supportive though and even supports fellows going into pharma, which is IMO nice as an applicant to see a PD who is so upfront and supportive of what you do even if it's not academics on the interview day.
Rutgers — solid academic center if you need to be around NYC but don't want to live in the city. Clinically very rigorous. They have minimal time blocked off for research in the 2nd and 3rd years but this year they're increasing the blocked off research time significantly (although still not quite as much as the best academic programs). There seems to be multiple avenues of research although fellow interest or support seems slim. Not a big fan of multiple EMR systems (separate inpatient and outpatient). They used to go to the Jersey shore for their community affiliate but due to reorganization they're going to a different hospital now (but still a 45 minute drive away).
Northwell — similar in many ways to Rutgers, also very clinically rigorous. Very curious program in the sense that there is no dedicated time for research but rather you can use the free time in the ambulatory blocks for research. All the faculty is very nice and supportive of fellows, and the fellows seem to get along with each other well. A side note is that despite the rapid expansion of the Northwell system, the main cancer center doesn't serve as the de facto referral center as they have a decentralized model where they want to build up different satellite cancer centers in the health system. This doesn't really affect the fellows too much but I don't know what this means in terms of gathering data for research, might be a headache if the EMR isn't fully integrated (which it isn't yet). They've recruited faculty from NIH to oversee their Phase I program.
Tufts — very small program where all of the cancer department (outpatient and inpatient) fit on the same floor of the hospital. The PD seems very involved in fellow education and personally oversees the research project of each fellow, as all fellows are required to have some kind of completed project prior to graduation. Interesting hospital model where each inpatient medicine team is led by a subspecialist (including renal, endo, GI, ID...etc.). Workload seems on the lighter side compared to other fellowship programs. Unfortunately, Tufts still seems significantly overshadowed in Boston by the Harvard programs and BMC (for the more public hospital/underserved flavor of care).
UNC — very solid program with a great balance of research and clinical care. The PD is nationally famous in several societies and is very supportive of her fellows — she also personally reviews every single application to the program! Fellows do a broad array of research including basic, clinical, translational, and outcomes. They have fantastic faculty in all areas. On the heme side, they have a stronger hemophilia presence compared to Duke. Outcomes research is stronger than Duke. Duke may be the same or better in terms of clinical and translational. Regardless, they really blaze their own path despite the proximity with another major academic program. Possible collaboration with various pharma in the Triangle.
Columbia — traditionally not considered a top-tier program but with the recruitment of a huge chunk of MSK faculty, they are rising in both research output and funding. Very strange interview day where interviewers didn't really ask any questions. Fellows come from brand-name residencies. Expanding rapidly and building a new cancer outpatient building currently. Possible access to other Columbia schools (like public health, business school, law) for research (but unclear which fellows currently do it). Lots of fellows win YIA awards (they ask all fellows to submit a YIA grant which is reviewed and critiqued by a panel of faculty before submission).
UC Irvine — traditionally significantly overshadowed by UCLA (and at one point their BMT program shut down), but everything is on the upswing now, with BMT reopening and faculty recruited to build the division (chief recruited from Tufts). Very interesting patient base comprised of affluent patients and mix of Hispanic and Asian immigrants in Orange County. Fellows also rotate at the VA (20 minute drive away) where more of the clinical teaching seems to happen. Very committed PD who is trying to recruit great classes of fellows.
Michigan — very well-rounded clinically and in research. Completely protected 2nd and 3rd years for research and fellows with great research output. One of the most impressive morning reports on the interview trail with very smart and engaged fellows. Very supportive leadership, has research faculty in all areas including other schools in the university campus. Fellows seemed happy and come from competitive residencies. If the program was located anywhere else, it would be among the very top tier in my opinion.
BU — program heavily focused on the public hospital/underserved population of Boston, which is great because they define their own niche in a city with 4 different heme-onc programs. Fellows are great but research output seems so-so. There's a tour of a stem cell laboratory on the interview day but apparently no fellows currently do research there? Anyways, the leadership seems very caring of the fellows though and they just recruited a big name from Harvard to be chief of their division, seems to be on the up-and-up!
Good luck to everyone in the future - the heme-onc match has gotten really competitive and I am honored to be training with such a great group of fellows as I saw in the applicants on interview day
