Subject RE: Identification of prostatectomy
Date Thu, 15 Oct 2015 17:40:12 GMT
Hi Sangram,

I would love to say that I have a simple answer for you, but I don't.  There is an engine
that will attempt to identify events as hedged, hypothetical, actual or generic ... the ContextualModalityAnnotator
in the ctakes-temporal module.  However, it is not in the commonly used pipelines, and I have
no idea how well it works.  It is possible that somebody else out there is using this annotator
to great success or at least knows more about it than I.

Subject: Re: Identification of prostatectomy

Many thanks, Sean!

I have patient-clinical-notes e.g.

   - 83 y.o. Asian gentleman who is status post a robotic-assisted radical
   prostatectomy in October of 2006 for pathologic stage T2c, Gleason 4+3
   prostate cancer excised with a negative surgical margin but benign glands
   at the margin.
   - The patient is a 73-year-old Caucasian  gentleman who is status post radical
   prostatectomy in 2006.
   - Greater than 30 minutes of face to face discussion time were spent
   discussing the prostate gland, prostate diseases and prostate cancer.  We discussed
   open radical prostatectomy, daVinci prostatectomy, external beam
   radiation, brachytherapy, cryotherapy, androgen deprivation, watchful
   waiting and HIFU.
   - We discussed different treatment options for prostate cancer. We
   discussed non-curative options including active surveillance and hormone
   therapy. We also discussed potentially curative options including surgery
   versus radiation and cryotherapy.

The note gets annotated using clinical pipeline - AggregatePlaintextFastUMLSProcessor.
By searching keyword I can find a treatment. sometimes physician writes about the discussion
and sometime the actual surgery. Now I have problem to finalise if the mentioned procedure/treatment
is really happened or just discussed.  I can't just rely on verb in the sentence.

Your help would help me a lot!
