    One year of breast cancer in Ibadan, Southwestern Nigeria: a histopathological review
    (African Journal of Open Libraries, 2021) Jimoh, M. A.; Ajani, M. A.; Folorunso, S. A.; Fatunla, E. O.; Aruah, C. S.; Abdus-Salam, A. A.; Ogunbiyi, J. O.
    Background: Breast cancer is a major public health problem in most low- to medium-income countries of the world because of its high morbidity and mortality rate. Histopathological features are vital in risk assessment, selection of treatment and prognostication in breast cancer patients. This study aimed to assess the histopathological features of all breast cancer cases seen in a tertiary hospital in the year 2018. Methods: This is a retrospective review of all breast cancer cases histologically diagnosed and confirmed by three Pathologists at the University College Hospital (UCH), Ibadan over a one-year period from 1st January 2018 to 31st December, 2018. Results: A total of 236 breast cancer cases were seen during this period, 234 (99.2%) were females while only 2 (0.8%) were male. 163 (69.7%) patients were between the fourth and sixth decades of life, 65 (27.8%) patients were above sixth decade while 6 (2.5%) patients were below fourth decade. Invasive ductal carcinoma of No Special Type (NST) was the commonest histological subtype 212 (89.8%). Grade 1 cases were 25 (10.6%), Grade 2 129 (54.7%) and Grade 3 cases were 40 (16.9%) while 42 (17.8%) were not graded. Lymphovascular invasion observed in 98 (41.5%) of the cases. 54 (22.9%) had immunohistochemistry out of which 23 (43.4%) were triple negative while 8 (3.4%) were triple positive. Conclusion: Histopathological features suggesting aggressive disease was predominantly observed. Efforts should be made towards early diagnosis, adequate evaluation and prompt treatment. Cancer care should be fully incorporated in the National Health Insurance Scheme (NHIS).

    Overexpression of human epidermal growth factor receptor 2 protein in urothelial carcinoma of the urinary bladder in Ibadan: a single-institutional experience
    (Faculty of pathology, national postgraduate medical college of nigeria, 2020) Fatunla, E. O.; Ajani, M. A.; Onakpoma, F. A.; Takure, A. O.; Okolo, C. A.
    Background: Overexpression of human epidermal growth factor receptor 2 (HER 2) protein has been shown to have both prognostic and therapeutic values in several malignancies including urothelial carcinoma of urinary bladder (UCB). Aims: This study aimed to determine HER 2 protein overexpression and evaluate its correlation with clinico pathological parameters in UCB. Materials and Methods: This was a descriptive-analytical study involving the immunohistochemical review of all histologically diagnosed urinary bladder malignancy in the Department of Pathology, University College Hospital, Ibadan, between January 2002 and December 2016. Urinary bladder malignancies whose tissue blocks could not be found and/or demographic data were not available were excluded. Immunohistochemistry analysis was done using rabbit anti HER 2 antibody (Biocare) and American Society of Clinical Oncology/College of American Pathologists guidelines established for breast cancer were used for HER 2 status scoring. The statistical analysis was carried out usingthe Statistical Package for the Social Sciences, version 22 (SPSS Inc, Chicago, Illinois, USA). Results: HER 2 overexpression was found in four (6.3%) cases. All the HER 2 positive cases were males. One (2.9%) of the 35 high grade UCB showed positive HER 2 overexpression, whereas three (10.7%) of the 28 low grade tumor were positive for HER 2 protein overexpression.There was no statistically significant association between HER 2 protein overexpression and histological grades of UCB and muscle invasion by the tumor. Conclusion: Our study demonstrated the low percentage of HER 2 overexpression in UCB with no significant association with tumor grades and muscle invasion. Larger samples involving multiple centers can provide more robust information and further evaluate HER 2 overexpression in urothelial carcinoma in our environment.
