Abstract

Background: Invasive breast carcinoma is the most common type of breast cancer among women globally, with high mortality. In Indonesia, it ranks first based on Globocan 2020 data. Objective: To determine the expression of prognostic and predictive markers—Estrogen Receptor (ER), Progesterone Receptor (PR), HER2, and Ki67—in breast cancer cases at RSUP Wahidin Sudirohusodo. Methods: A descriptive study was conducted on 71 samples from 2021–2023. Data on age, histopathologic grade, and marker expression (HER2, ER, PR, Ki67) were analyzed. Samples were stained and examined microscopically. Chi-square tests were performed using SPSS version 27. Results: Among the 71 samples, 47.89% were from patients aged < 50 years and 52.11% from those >/ 50. Grade 2 was most common (59.15%). HER2 expression was negative in 59.15% of samples, ER positive in 83.10%, PR positive in 67.61%, and Ki67 expression was low in 52.11%. Conclusion: Most cases showed negative HER2 and positive ER/PR expression with low Ki67, indicating the relevance of hormonal receptors and proliferation rate as prognostic indicators. These markers are crucial for prognosis and treatment planning in breast carcinoma.

Abstract

Background Primary thyroid leiomyosarcoma is a very rare tumor. The incidence is less than 0.01% of all primary thyroid tumors. Thyroid leiomyosarcoma are tumours showing smooth muscle differentiation, originating from thyroid gland vascular smooth muscle. Case Description Female, 47 years old, with lump on the left neck since 1 year ago, getting bigger in the last 3 months, no shortness of breath, no history of previous surgery. Physical examination revealed a mass was 13x6 cm in size, solid, firm.  Cytological features from fine needle aspiration biopsy (FNAB) showed cellular spindle cells with atypical, pleomorphic, hyperchromatic nuclei and  several normal thyroid follicles among them, sugesting  malignant thyroid tumor (Bethesda VI). Total thyroidectomy was performed, followed by histopathological examination. Microscopically showed proliferation of atypical, pleomorphic, hyperchromatic spindle cells with eosinophilic cytoplasm. The spindle cells arranged in fascicular and interlacing pattern. Several follicular thyroid are entrapped within this atypical spindle cells. Based on these finding, this case was diagnosed as anaplastic thyroid carcinoma. To confirm the diagnosis, immunohistochemical examination with cytokeratin, desmin and Ki-67 were performed and the result showed negative for cytokeratin, positive for desmin and Ki-67 was highly positive. Based on these results, a diagnosis of thyroid leiomyosarcoma was made. Discussion and Conclusion Differential diagnosis with other primary mesenchymal thyroid  tumors should be considered in the cases with atypical spindle cells microscopic appearance. The diagnosis of thyroid leiomyosarcoma based on cytology and histopathology is difficult to establish, therefore immunohistochemical staining is required to establish the accurate final diagnosis.
