El día de ayer mientras "surfeaba" en la red como cualquiera de nosotros , buscando los temas que son de nuestro interés . Me topé con el siguiente In Memoriam:
Harold J. Isard MD.
Pionero en la Roentgenología , Detección Temprana de Cáncer de Mama y Curiosamente un Investogador Activo en esos días
(1970´s) de la Termografia Mamaria .
DISCUSIÓN Y RESUMEN EN EXTREMO INTERESANTES.
Ahora Bien :
(1970´s) de la Termografia Mamaria .
DISCUSIÓN Y RESUMEN EN EXTREMO INTERESANTES.
Ahora Bien :
"Personalmente apoyo el uso de la Mastografía como el procedimiento diagnostico angular support the use of Mammography as the cornestone procedure for breast cancer morphological detection , its frecuency and age to do it vary greatly and depend on multiple variables and environments.
It is indicated most certainly individualy , depending mostly on risk factors and local statistics.
Finally clean , ethical , expert clinical judgement after useful information after image procedures render the better understanding , certified recommendations and possible outcome.
Thermography stands alone as a potential metabolical , vascular , inflammatory or infectious study that can help against breast cancer" EMC
Now Dr. Isard mentions :
- He affirms that THERMOGRAPHY Cannot diagnose cancer , but hey Only Pathology diagnoses Cancer.
- He states that THERMOGRAPHY can obtain ABNORMALITIES......
- He sustains even then that MORTALITY HAS NOT CHANGED ( And guess What , according to NEJM latest Review it Seems that AFTER 30 years of Screening with Mammography MORTALITY HAS NOT CHANGED THAT MUCH EITHER) Hard to believe but the facts have been published recently.....Controversy goes on
- He suggests Thermography as a PRELIMINAR STUDY before Physical Examination and Then Mammogram ( SOUNDS REALLY CRAZY I MUST RECOGNIZE and OUR DETECTION and DIAGNOSTIC APPROACH ALGORITHM has changed quite a bit since then.
- No wonder WHY THERMOGRAPHY was put aside , IMAGES were REALLY CONFUSING , digital era may give it a new opportunity.
- He mentions Thermographic difficulties for specificity , REMEMBER BIRADS IV is 5-95% specific as well.
- He Highlights Vascular Patterns.
- He Remarks how CONSTANT and UNCHANGED the thermal PATTERN is.
- Regardless of the Date During The Menstrual Cycle , the "patient" or volunteer could be EASILY RECOGNIZED and Hence abnormalities also could be defined.... and monitored.
- Guess what : he mentions that the Thermal Image is RELATED to the BIOLOGICAL BEHAVIOUR of the SUSPECTED LESION........I constantly repeat this statement through my blog
- He identified IN SITU lesions as well as Metastatic. I will show you some of this later .....future cases.
- "The DEVELOPMENT of an ABNORMAL PATTERN when compared to a normal baseline study must ALWAYS be viewed with extreme suspicion" I have a sample case....
- Emphasizes Clinical JUDGEMENT to reduce UNNECESARY SURGERIES ( of course we now have minimal invasive procedures that can be applied) yet interesting point.
- Thermography was DIVIDED into POSITIVE or NEGATIVE ONLY , I believe its meaning is METABOLIC then its contribution has to be METABOLIC ALSO . 0 or 1 seems too simple.
- Thermography ALONE Cannot Beat MAMMOGRAPHY.......That is very clear for me and for everyone no controversy on that.....(specificaly on morphological meaning.....)
- Yet he mentions :"Since Thermography and Mammography did not always suspect the SAME lesion , the USE OF BOTH studies INCREASED ACCURACY to 92% when either or both examinations were POSITIVE.How about that....
- Thermography ACTUALLY IMPROVED Clinical Examination, now if we still Recommend Clinical Examination CAN WE REINTRODUCE Thermography during the Highly Specialized Breast Physical EXAM????
- BACK then CONTRALATERAL CLINICALLY NEGATIVE BIOPSIES were Performed , astonishingly some of them Positive for Beast Cancer...........so CANCERS EXIST but they do no harm EVER? Back to NEJM recent DATA.}
- With Thermology Technology in Those days : 61% of asymptomatic patients with cancer were identified , I wonder if now Digital Infrared Analysis of the Breast Can do Better?
- Thermography Improves DIAGNOSTIC ACCURACY , for me only used by and reserved for ONCOLOGISTS.
- Could EMERGE as a preliminary Screening Procedure .....Uuuffffff.....SHAKY GROUNDS indeed : Heavy evidence against this proposal , greater economical interests and maybe Political as well. Not to mention Status Quo and Orthodox Mentalities....
- Mammography detects around 1-6 cases per 1000 of screened women , I believe this ratio is still the same . But if I am wrong please do not hesitate to correct me.
- Mammography PLUS Thermography 7.3-1000 ( Can THIS SINERGY be Better Nowadays?)
- Here comes the TRICKY NUMBERS if USED as a PRELIMINARY STUDY that is BEFORE MAMMOGRAPHY: 21 cases per 1000 mammograms. This would mean BETWEEN 3 to 20 Times FEWER mammograms done. (uupppssss oh oh do the NUMBERS please)
- BUT : 10 cancers were NOT DETECTED By IR , and that is the reason for NON STOP MASSIVE MAMMOGRAPHIC XRAY SCREENING , I think these 10 cancers would have a BETTER prognosis even if undetected , I suspect LOW METABOLIC HEAT and a "Benign" Biological Behaviour........sounds reasonable? In other words maybe those not identified do not actually kill anyone.......interesting.
- And finally he states the INHERENT difficulties for an OPTIMAL MAMMOGRAPHY SCREENING PROGRAM.
Reality Bites.......
Can we focus attention in Female Patients with Suspicious PATTERNS?
Can we Define this PATTERNS AGAIN PROSPECTIVELY? With the help of Mammography?
After all the common enemy is BREAST CANCER , right?
