Is Breast transillumination a viable option for breast cancer screening in resource limited settings?

ASOU AGM Fort Portal, Uganda

MD (Dar), MMed Surgery(MUK)

FCS (ECSA) trainee,

Registrar

Colorectal Surgery Unit

Mulago Hopsital

what is the problem
What is the problem?
  • Breast cancer
    • Common disease(Gakwaya et al)
    • Rapidly rising incidence(Parkin et al)
    • low overall survival-56%(Gakwaya et al

ASOU AGM Fort Portal, Uganda

problem cont d
Problem cont’d
  • Prevention
    • No effective primary prevention(Gakwaya et al)
    • Secondary prevention is best hope(Prasad et al)
    • No screening program

Mammography

    • Internationally accepted effective screening tool(Brittenden, Nelson)
    • Not feasible for poor resource country like Uganda(Gakwaya et al)
      • Age limit (> 30 y)
      • High Cost
      • Inequitable distribution

Breast transillumination is

    • Safer (IR vs. Xray)
    • Cheaper ($150)
    • easier to use(self exam)
    • minimal running costs
    • No age limit
  • How does it perform in comparison with MG?

specific objective 1
Specific Objective 1
  • To determine the sensitivity, specificity and predictive values of breast transillumination compared to mammography in the evaluation of breast lumps among Ugandan women at Mulago hospital

comparison of transillumination to mammography
Prevalence from MG=63.2%, transillumination=45.3%.

Sensitivity = 63.2%, PPV= 86.8%

specificity = 89.5% NPV= 61.2%

Our study

literature

  • Average size 1.5 cm (range 0.5-4cm)
  • 61.2% BIRADS II
  • 50% close to chest wall
  • Relatively small/thin breasts
  • Lumps close to chest-SICKLER
  • Lumps in relatively small breasts CUTLER

case for low cost screening
CASE FOR LOW COST SCREENING
  • High burden of disease
    • Rapidly rising incidence
    • 77% present in stage III & IV
    • Peak age 30-39 years
    • Survival stage
  • Mammography
    • Expensive
    • Inequitably distributed
    • Excludes women less than 30 yrs

ASOU AGM Fort Portal, Uganda

bold suggestion
Bold suggestion
  • Preliminary data shows that BT is possibly comparable to Mammography
  • Let us rethink breast cancer screening and diagnosis
  • Get breast transillumiantion off the dusty shelves

ASOU AGM Fort Portal, Uganda

limitations
limitations
  • Hospital based study on symptomatic women
  • Learning curve for breast transillumination
  • Age limit of 30 years

ASOU AGM Fort Portal, Uganda

recommendations and prospects
Recommendations and prospects
  • Large scale population based evaluation as a screening tool
  • Evaluate
    • Sensitivity in asymptomatic population
    • Intra/inter-observer variability
    • Acceptability
  • Grand Challenge Canada application
