What others say about us

“I love the comprehensive nature of the app – I don’t need to use multiple apps to stage then look for prognosis, discuss adjuvant benefits, calculate BSA, GFR, carboplatin doses, etc. It also has the CTCAE criteria to grade adverse effects built within it when seeing trial patients.
The more you use it, the more you discover and realise how much is contained within it. The other great thing is that the developers are very keen to listen to feedback and I have seen many great changes implemented over the time I’ve been using it and providing feedback.”

“Instead of having to print out reference material, or make repeated online searches, I can find the data I need using ONCOassist whenever I want it. Additionally, I have found the ONCOassist team are adding regular updates.”

“ONCOassist allows rapid access to a wide range of evidence-based tools which can inform both the clinician and the patient, and which have the ability to focus the consultation on the most pressing aspects of a patient’s treatment journey.  Importantly, at a time when clinicians are increasingly under time pressure, ONCOassist also facilitates easy, rapid access to commonly used clinical algorithms and calculators, thereby promoting both efficient and safe clinical practice, and it seems inevitable that it will increasingly be adopted by busy trainees, both within and outwith oncology.”

“Surprisingly useful. This app is really what was missing for oncologist with interest in technology. Normally I would use up to 3 ups for dealing with the needs of a patient, and now I can find everything in the app. It is important to mention how available the developers are. I hope to contribute to make this app even better. Definitely recommended.”

Love it

Very helpful little tool especially in busy clinic. I hope survival prediction will be added to more cancers over time. 5 stars.

A big thank you

I’ve been using this app for more than a year. It’s one of the most used apps on my phone. I was using it for staging, calculators and to calculate the benefits of adjuvant treatment in colon cancers. The introduction of adjuvant tool for breast cancer was long awaited. They have done it with this update. It was totally worth the wait. Invaluable app for a medical oncologist like me. A big thank you to the developers and ESMO for making this available.

The formula section alone deserves 10 stars, I wonder how awesome other paid features will be.

Fast and reliable

Easy to use app. Has many of the tools that I would use daily at work. Fast and reliable! CE approval is a big plus too especially when important calculations such as dosages are given on the app.
