Item Development of risk prediction model for endometrial carcinoma among postmenopausal women in the Western Province.(Sri Lanka Medical Association., 2019) Jayawickrama, W.I.U.; Abeysena, H.T.C.S.INTRODUCTION & OBJECTIVES: Risk prediction model can be used to estimate the probability of developing endometrial carcinoma among postmenopausal women. The aim of the study was to develop a model to predict the risk of endometrial carcinoma among postmenopausal women. METHODS: A case control study was conducted. The cases and the controls were defined as postmenopausal women who had and had not been diagnosed as endometrial carcinoma based on histological confirmation respectively. Variable selection was done considering the objectivity and feasibility of the measurements in addition to the statistical criteria. A scoring system [ 1-9) was designed based on weighted score of each risk predictor. Predictive validity of the model was tested by calibration and discrimination. Receiver Operator Characteristic (ROC) curve was used to determine the cut-off value. RESULTS: The developed model consisted of six predictors: Age >55 years, never conceived, age at menarche ≤11 years, ever experienced postmenopausal bleeding, having family history of any type of cancer among first degree relative, generalized obesity. Discrimination of the model was measured by the area under the ROC curve (0.92, 95% Confidence Interval: 0.88-0.95). Calibration with goodness of fit by Hosmer and Lemeshow test (p=0.72) was satisfactory. The tool demonstrated a good predictive ability with sensitivity of 89.2% (Cl: 79.9%-94.6%) and specificity of 76.2% (CI: 79.8%-80.3%) at the cut-off point of 3.5. CONCLUSION: Model demonstrated good discrimination and calibration. It can be used in screening of high risk women for developing endometrial carcinoma in the community.Item Incidence of carcinoma among THY3 lesions of the thyroid(Sri Lanka Medical Association, 2016) Kumarasinghe, K.A.P.R.; Pinto, M.D.P.; Munasinghe, B.N.L.; Dissanayake, D.M.C.D.; Abeyrathne, I.G.K.P.; Amaraweera, P.C.; Fernando, R.INTRODUCTION AND OBJECTIVES: Ultra Sound Scan (USS) and Fine Needle Aspiration Cytology (FNAC) of thyroid nodules are carried out in patients with goitre. THY3 lesions cause diagnostic difficulty and risk of malignancy in such lesions is 20%. The objective of this study was to determine the incidence of carcinoma among THY3 lesions and to relate the findings to the size of the nodule. METHOD: All the patients who underwent thyroidectomy at the University Surgical Unit, Colombo North Teaching Hospital from November 2002 to December 2015 were analysed retrospectively. Histological and ultrasonic data in patients with THY3 lesions were analysed. RESULTS: There were 29 (5.68%) THY3 patients among 510 patients who had thyroidectomy. Only 6 (20.7%) patients were histologically proven to be malignant (follicular carcinoma – 3, papillary carcinoma - follicular variant- 2, mixed medullary papillary carcinoma - 1). All patients were females (age range 17y -52y). Pre-operative USS nodule size in the malignant group ranged from 2.6 cm to 6.8 cm (average - 4.25cm). 20 patients (68.9%) had benign histology (MNG - 18, thyroiditis-2). USS nodule size in the benign group ranged from 2.3 cm to 2.5 cm. Three patients (8.7%) were lost to follow up. CONCLUSIONS: About 20.7% of THY3 lesions had thyroid carcinoma. Lesions larger than 4.25 cm were more likely to harbour a malignancy.
