Abstrakt: ER/PgR testing are now routinely performed in breast cancer evaluation in Southeastern Nigeria. ER is predictive to show beneficiaries of hormonal therapy and a prognostic marker to establish tumors that will resist paclitaxel induced apoptosis so a cost effective combination of anthracylines can be used as treatment in our low resource setting thus improving survival, reducing recurrence, and cost. Four hundred seventeen cases of breast cancer seen over a period of 3 years were routinely tested for ER/PgR. ER positivity was defined as nuclear positivity of 1% in the presence of internal and external controls. Four hundred seventeen patients with Ductal Carcinoma participated. Majority were females 98.3%. Majority 60.2% were between 31 and 50 years old. Mean age was 33.5 ± 6.4 years. Two hundred fifty-seven (61.6%) were positive both for ER/PgR. 70.3% of age group 41-50 years had positive ER, age groups 20-30, and >70 years had positive ER also. ER positive cancer was 60.2%. Fifty-seven were 1%-9% positive. Most positive estrogen receptors were seen between 41 and 50 years at 70.3%. Least was seen at 31-40 years at 51.4%. Study provides an objective basis for using hormonal manipulation and makes cost affordable with appropriate chemotherapeutic agents in our low resource setting. Presentations were typically late. Seventy-six percent of stage 2 disease survived after 6 years compared with only 56% of stage 2 disease prior to immunotyping and radiotherapy in 2007. Both stage 3 and 4 had remarkable survival too at 55% and 33% respectively when compared with 2007 figures at 33% for stage 3 and 9.2% at stage 4.
