Was reading through this fantastic piece 10.1016/j.ejca.2023.113357 by Alexander Sherry Pavlos Msaouel Ethan Ludmir MD I love this section specifically - keeping in mind the noncollapsibility in the context of odds ratio or hazard ratio. I learn everyday from these folks!

PLATO ACT 4: Ph II RCT of 50.4 vs. 41.4 Gy for T1-2 (<4 cm) N0 anal SCC. No difference in 3-year local recurrence (primary endpoint) or OS, & better toxicity/QOL with dose-reduction. Should 41.4 Gy be a SOC option (ahead of Ph III DECREASE trial reporting)? #ESTRO25

Deeply saddened that the entire team NCI Cancer Control National Cancer Institute PDQ Cancer Information has been eliminated. Our evidence-based summaries were updated throughout the year with the latest evidence and supported informed decision making between clinicians & patients across the US. 🇺🇸

Wow, this trial showed no OS benefit to FOLFIRINOX vs. single agent gemcitabine in locally advanced pancreas cancer (different than adjuvant & metastatic trials - both w OS improvement!) PFS increased by 2 mo, but this came at cost of increased toxicity, $, treatment burden.

The most underrated career skill is the ability to receive tough love. Acquiring knowledge is easy. Obtaining constructive criticism is hard. If you can't handle the truth, people stop telling you the truth. The people who grow the most are the ones who take feedback the best.

Dr Amol Akhade OS not statistically significant per p<0.05 definition but that’s clinical very significant. Interestingly, it is rather similar to how the FLOT arm did in ESOPEC

‼️ TAUTEM Phase 3 RCT T2-3bN0M0 rectal cancer -> chemoradiation and transanal excision vs TME DFS in both groups was 88.9%! Win for organ preservation and patients! jamanetwork.com/journals/jamas…

🧵1/ Big news in unresectable stage III NSCLC. The InTRist study is the first randomized trial comparing NAC vs. neoadjuvant chemoimmunotherapy (NAC-ICI) prior to definitive chemoradiotherapy (CRT). Early results are promising. Let’s dig in. 🔍 #LungCancer #RadOnc #ASCO25

What happens when you query chatGPT with 362 breast cancer cases? -46% responses differed from breast cancer expert opinion -when the same case was entered 3 times, the responses differed ~2/3 of the time ! -for examples, see 🧵..

This will grab headlines but they used the ChatGPT 4 model which is for basic reasoning, which I would not consider tumor board to fit this. The o3 model actually reasons and would be at least a fighting chance. I have put it to the test with very complex scenarios with
