Background: Tumor budding is a histopathologic entity refers to small cluster of cancer cells at the invasive edge of tumor. It was assumed that tumor budding is linked to epithelial-mesenchymal transition, an early event in metastasis. Objective: This study aimed to find out the correlation of tumor budding with E-cadherin and MMP-9 expression and risk of metastasis in breast carcinoma. Method: We investigated 35 cases breast carcinoma with metastasis and 35 cases without metastasis. The number of tumor budding was counted in cytokeratin-stained slides with 400x magnification (0.57 mm 2 ).Result: Cut-off point by ROC analysis was 11 and the patient was categorized into low grade (0-10 buds) and high grade (11 or more buds) tumor budding. Inter-observer agreement was good with K value 0.914. Low level of E-cadherin was not significantly correlated with high grade tumor budding (p=0.660), meanwhile high level of MMP-9 was significantly correlated with high grade tumor budding (p=0.001). High grade tumor budding was a significant, independent risk factor of metastasis in breast carcinoma (OR=38.2, 95% CI 7. 5-193.7, p<0.001). Conclusion:In conclusion, tumor budding grade is related to level of MMP-9 but has no correlation E-cadherin expression. High grade tumor budding is an independent risk factor of metastasis in breast carcinoma.

Background: Breast cancer is a malignancy originating from breast tissue. In Indonesia, the prevalence rate of breast cancer is 0.5% or around 61,628, and the incidence of breast cancer in Bali reached 0.6% in 2013. The aetiology of breast cancers are multifactorial, and the main factor is still unknown. This study aims to determine the prevalence and characteristics of breast cancer patients in the Sanglah General Hospital oncology surgery clinic. Methods: This study was a descriptive cross-sectional study. The sample used was a patient suffering from breast cancer who visited Sanglah General Hospital's oncology surgical clinic, both outpatient and hospitalization in 2016 and was willing to submit informed consent. Variables assessed in this study were age, education level, jobs, symptoms, history of breast cancer, the staging of breast cancer, and type of medication. Data were analyzed using SPSS version 17 for Windows. Results: The results showed the dominant sociodemographic characteristics of respondents in the age range 41-50 years as many as 27 people (42.18%), had an education level equivalent to senior high school 27 people (42.18%), worked as private employees, and there were 23 entrepreneurs (35.93%) from 62 samples. Other characteristics obtained 55 people (85.94%) respondents experienced initial symptoms of lumps in the breast, 13 people (20.31%) respondents had a family history of breast cancer. A total of 13 patients (20.31%) claimed to use herbal medicine, and 7 (10.94%) admitted to undergoing alternative treatment other than treatment in Sanglah General Hospital, Bali, Indonesia. Only 43.75% decided to seek treatment for their own sake. The majority of patients, as many as 41 people (64.06%) were diagnosed in stage III.Conclusion: People living with Breast cancer at Sanglah Hospital have a younger age compared to the majority of breast cancer sufferers in the world. Lack of knowledge of women about breast cancer itself is one of the causes. Latar Belakang: Kanker payudara adalah keganasan yang berasal dari jaringan payudara. Di Indonesia kanker payudara merupakan kenker dengan angka prevalensi kejadian 0.5% atau sekitar 61.628 dan kejadian kanker payudara di Bali mencapai 0.6% pada tahun 2013. Penyebab kanker payudara termasuk multifaktorial yang belum diketahui penyebab utamanya. Penelitian ini bertujuan untuk mengetahui distribusi prevalensi gambaran karakteristik penderita kanker payudara di poliklinik bedah onkologi RSUP Sanglah.Metode: Penelitian ini merupakan penelitian observasional deskriptif cross-sectional. Sampel yang digunakan merupakan pasien yang menderita kanker payudara yang mengunjungi poliklinik bedah onkologi RSUP Sanglah baik rawat jalan maupun rawat inap pada tahun 2016 dan bersedia mengisi informed consent. Variabel yang dinilai dalam penelitian ini adalah usia, tingkat pendidikan, pekerjaan, gejala, riwayat kanker payudara, stadium kanker payudara, dan jenis pengobatan. Data dianalisis menggunakan SPSS versi 17 untuk Windows.Hasil: Hasil penelitian menunjukkan karakteristik sosiodemografi responden dominan berada pada rentang usia 41-50 tahun sebanyak 27 orang (42,18%), memiliki tingkat pendidikan setara Sekolah Menengah Atas (SMA) sebanyak 27 orang (42,18%), bekerja sebagai karyawan swasta dan wiraswasta sebanyak 23 orang (35,93%) dari 62 orang sampel.
