Breast Digital Infrared Analysis (DIRA) , a forgotten and set aside procedure.

Visita: termografiamamaria.blogspot.com (Version en Español)

Breast DIRA (previously named Thermography) already proved in the past that it´s use as an screening procedure had low specificity and high sensitive values for it to be recommended as an standard care Breast diagnosis tool .
Yet , until recently (last 5 years) active research mainly by Surgical Oncologists or Breast Surgeons have published interesting results.( Cornell NY , Addenbrooke Cambridge , Ville Marie Montreal , Taiwan and Mexico CEPREC)
FDA previous published criteria were prohibiting DIRA as well as the A.C. of Radiologists ( as an initial SCREENING TOOL)

Yet it has been cleared by the FDA approval as an adjunctive screening tool for breast cancer .( under 510 k) .

DIRA´s meaning is not an ANATOMIC or ARCHITECTURAL procedure ,it is a METABOLIC or PHYSIOLOGIC ONE so at first it ´s current recommendation should be only as a COMPLEMENTARY STUDY.

As such DIRA could help in specific scenarios, BIRADS 0,3,4 and give potential useful additional data in BIRADS5. EVEN BEFORE BIOPSY
Could aid mammogram in young,dense and breast prosthesis patients, and should be evaluated in other clinical scenarios as a Neoadyuvant Monitoring tool.
Finally as an early detecion procedure specifically in underdeveloped countries , could Triage in search of aggresive forms of the disease(T1,G2_G3). And aid Physical Exam of the Breast .

Case Number 7. Previous Lobullar Carcinoma. "Earlier Detection" , SyneIRgy" , "TABB"


 Case Number 7 . 


Female patient , Medical Dr: General Practicioner.  48 years old , with  familiar history in one aunt for breast cancer , 2 years previously  (2007)  during self exploration of an irregular right sided nodule she  attended to her physician  and after a difficult and irregular diagnosis algorithm  and a delay of 4 months , we decided to perform a biopsy :


 Invasive Lobullar Breast Carcinoma
 Negative for HER 2 neu and Hormone Receptors


Stage IIB :  T2N1M0 , she underwent a Radical Mastectomy , with a lesion of 4 cm and 2 positive lymph nodes and after wards standard adjuvant treatment


2009 after 2 years in control , conventional image studies were performed  :



Remaining Breast Mammogram  Lateral Oblique View  : dense breast tissue in her inferior quadrants  , superior isolated density with a "linear" aspect. 
 Cefalo Caudal view : persistance of the density in th upper and now external quadrant  . And internally an ovoidal  density
Close up for the superior density. No calcifications were seen. 


Magnification  of the upper and external density  , 
compatible with a linear " scar "image no 
calcifications were delineated either. .
Magnification of the internal lesion , opaque and ovoidal  





















Ultrasound definition of the latter.  


Final Radiological Report  . 

BIRADS IV because of the presence of the INTERNAL LESION
Density towards the Spence tail of the breast
 was mentioned , yet specifically with out the 
need for a Biopsy. 

Digital Infrared Analysis as a complementary procedure : 




Evidence for an isolated Hiperthermia , that persists even after the cold sitmuli in the functional part of the study in the upper outer quadrant of the remaining breast (left) that is coincidental with the density defined in mammogram .


Suspicious by this method  with and IR Score of 125 , Peripheral Tissue delta between basal and functional studies of  1.3 degrees (obviously there is no  comparison with the contralateral breast )   









Close up for the IR  IMAGE , superior arrow corresponds to my radiological interesting area  and the reported by radiology  internal nodule (palpable) "invisible" or absent by this means. 








Which translates :  


  Suspicion for the upper lesion : Higher metabolic generation , vascular density , vasodilation , inflammation or infection . 


And  in the internal :  low heat or low  infrared radiation generation : low metabolic index  : low vascular density  , no inflammation or infection.

Having and informed consent ( patient is also a Medical Doctor)  we decided to perform both biopsies  . 


In the upper outer quadrant the IR area was delineated , lumpectomy 5 cm width was performed  down to the pectoralis major fascia . For it to be sure that no breast tissue was left behind.  


"Thermographically Assisted Breast Biopsy : TABB" you can google :" Biopsia de mama asistida por termografía

And complete biopsy of the internal nodule.



Macroscopically , the initial tissue of the lumpectomy was not revealing , yet the inferior was compatible  macroscopically and microscopically  with a benign breast fybroma.

Microscopical Images for the UPPER LUMPECTOMY  SPECIMEN: 



Definitive PAthological Report:

Atypical Lobullar Hyperplasia with , microcalcifications. Some other expert pathologist diagnosed it even as a lobullar carcinoma insitu. 


Comment: 
  • Lobullar Carcinoma is a neoplastic entity of difficult diagnosis , even with the most recent or advanced current image procedures. Its incidence is around 10% or less of the total number of cases.
  • So diagnostic mistakes are common  , even clinical palpable lesions are hard to define  with limits and consistency similar to an irregular "cushion"
  • Also it has a multiple lesion behaviour , in foci , centers or even bilaterally.
  • Hence metachronic lesiones are probable and common.
  • Atypical Lobullar Hyperplasia could progress  as high as 30% of the cases with an invasive form of the disease
  • Definitive treatment depends of common agreement and consensus with the patient and with the available resources , some recommend even PROPHYLACTIC  MASTECTOMY.

In this specific case  , she finally decided to have a Prophylactic treatment  so : Simple left mastectomy was performed and she started breast reconstruction.


By now she is well after 5 years of initial diagnosis and 2 years after completing breast reconstruction.  

Hypothesis:

Some Breast IR "promotors and supporters " sustain that Breast Thermography can detect lesions 8 to 10 years before Mammogram 

In my own point of view I believe this declaration is not believable and unrealistic and should be rejected by  Our scientific community (actually it is) . 


So we assume ,consider and agree that  this statement is  false doubtful  and even dangerous . 

"Yet not all of it is totally  incorrect ".EMC

Otherwise  , specific scenario exists :

  •  in high risk patients , 
  • with previous history of malignant lesions of difficult diagnostic and clinical behaviour  ,
  •  with doubt to recommend a  biopsy in the standard image studies 8mammogram and USG ) , 
  • Located in  most frequent site (statistically)for breast cancer : Upper External Quadrant. 



And coincidental between IR findings and mammographic ones: 

" DIGITAL INFRARED ANALYSIS OF THE BREAST IN EXPERT AND CERTIFIED HANDS, COULD HELP IN A SYNERGISTICAL WAY WITH THE CURRENT IMAGE PROCEDURES FOR THEM TO DETECT  EVEN  :

PREINVASIVE LESIONS" 

 EMC.

This specific case can only be seen by an experte in breast pathology , either an oncologist , breast surgeon o radiology trained a breast image expert.

So in this particular NICH of the breast cancer population  IR could  help  and  sustain therapeutical or eben prophylactical decisions

Finally

Mammography still is and will be the CORNER STONE of breast cancer detection through good quality screening program .


Yet :  Initial age of Screening  and it´s frequency is controversial even between experts  , it depends on race , cultural , economical and personal factors . 


It is also related to the corresponding  Breast Cancer Statistics for a given population , 


Human resources and quality of the available equipment , technique are also important  and finally the personal interpretation experience  is a decisive factor for it to be consistent-

Regretfuly , political and some enteprise interests are commonly involved. At least that is what I feel and find it not so hard to believe.


So:

"Mammogram :  Is a very complex medical diagnostic procedure."

Breast Thermography is a reproductible method , with objective values that could help synergistically  the available diagnostic armamentarium . 


Should be thoroughly re-studied  by Breast and Oncology Experts in  controlled , prospective protocols  and  preferably in mulcenter coordination.
