80% gynecological oncologist Västerås 🇸🇪. 20% HTA-unit Camtö Örebro Hospital. Views my own. Too dumb and lazy for doing research but interested how to evaluate medical research&evidence. Words matter. Dislike lifscience like QoL&D engl, swed, germ

Skrev i senaste "Rapport om läkemedel" från Läkemedelskommitén Örebro om Camtös systematiska översikt över torkat svinsköldkörtelextrakt mot hypotyreos och en kartläggning av dess förskrivning i Sverige. Så snygg illustrerat. Tacksam för kritisk läsning.

Lite väl positiv framställning på P1 Fabriken av AI inom sjukvården och diagnostik. Jag rekommenderar istället på fredag Cantös temadag "Varför så bråttom?" med en föreläsning om "Evidensgranskning av AI-baserade och andra medicintekniska produkter" och "Lärdomar av sjukvårdens digitalisering"

One of the most fascinating academic-driven concepts in oncology is de-escalation. As the rich countries lived delusionally as if their resources were unlimited we are starting to learn from countries like India. Swedish Society of Oncology changed for almost 2 yrs ago to weight-based immunotherapy

Pharma Is Pushing $200,000 Cancer Drugs When Cheaper Doses May Work

In my opinion the critique by non-expert in exercise physiology John Mandrola in www.sensible-med.com/p/exercise-i... was pulverized. It may be time for all cancer units globally to start working on implementing a structured exercise program for its cancer patients. #commonsense

Exercise is Great but It’s Not a Cancer Drug

The CHALLENGE trial ignited social media with its great story of exercise as a cancer therapeutic. But liking a conclusion is not a reason to stop thinking.

I witnessed yesterday probably for me the best presentation ever of a cancer trial listening to a @csoncol.bsky.social session about the CHALLENGE-trial by Chris Booth with a hell of a ride & tour de force in the Q&A. Very inspiring comments by @eaeisenhauer.bsky.social

Thats why HTA-units are so utterly important for every knowledge-driven society. Very interesting read by the way with refreshing balance.

A quick post about the whole paracetamol thing, and can people stop saying there is 'no evidence'.

There is, but the balance of evidence and the strongest studies don't show a link.

You say acetaminophen , I say paracetamol

Paper out today in PLoS Medicine by many of us who would like to see publication bias reduced or eliminated.

Especially happy that Registered Reports got shout-outs.

Looks also like a good learning example to illustrate the importance of taking your time to think through your PICO before starting a systematic review. In the search strategy they used "colorectal cancer" without mentioning rectal cancer or premalign lesions under exclusion-criterias.

Science is not always as good as it appears on print in a research paper. Ready to be scared by finding nasty truths. Try out INSPECT-SR for checking the trustworthiness of trial results when you do systematic reviews.

One of the most common misunderstandings about the use and value of placebos in clinical RCTs, often made by both methodological experts and experienced trialists:

(from @stephensenn.bsky.social in academic.oup.com/jrsssa/advan...)

A further problem is illustrated by the authors equating no treatment with placebo. For example, describing their second assumption, they state, ‘Implicit in this notation is that there is a single version of ‘no treatment’ that is consistently defined across all subjects in the RCT and external controls’ (p4). However, most clinical trials are add-on trials (Senn, 2002), even if not specifically identified as such. In placebo-controlled trials, one starts with standard of care and then subjects are either allocated to receive in addition the active treatment or a placebo to it. The statistical analysis plan for SUNFISH (F Hoffman-La-Roche Ltd, 2020) has a protocol summary as Appendix 1, which has this to say, ‘In addition to the study drug treatment, patients may continue to receive concomitant drug medication…’ (p186). This is very standard for clinical trials. It highlights that a key assumption in borrowing control data in this way is that there has been no evolution in the standard of care in the period since the trial.

Hon är ju sist så det går utmärkt att ta till sig de övriga föreläsare. Min personliga highlight är Mikael Hoffmann. Som jag saknar lakemedel från twitter-tider. Jag är helt medveten om att Agnes känns upprörande för en del av svenska befolkningen. En del älskar henne. Vi vill hålla oss till mitten.

The scandal of unbelievable bad medical research gets the well-deserved public attention unfortunately only occasionally in highly polarised and politcized questions.

There's been a big fight over gender-affirming care after Gordon Guyatt and his team at McMaster released a statement contradicting their former funders' public policy.

I wrote about the whole thing, and what "evidence-based medicine" really means.
