Abstract: Breast cancer is the most common cancer in woman. Metastasis often occurs especially to the bones. This study was aimed to determine the characteristics of breast cancer patients with bone metastasis. This was a descriptive study with a cross-sectional design. Samples were 46 breast cancer patients with bone metastasis recorded at Sanglah Hospital from 2014 until 2018. Data of pathological examination archives of Oncology Surgery Division Medical Faculty of Udayana University/Sanglah General Hospital were used to obtain the clinicopathological characteristics of metastatic breast cancer patients based on age, lateralization, histopathological type, and tumor molecular subtype. The results showed that most cases of metastatic breast cancer were aged 40-49 years as many 21 patients (45.7%), minimal difference in lateralization between right breast as many 22 patients (47.8%) and left breast 23 patients (50%). The most common histopathological type was invasive carcinoma of no special type as many 34 patients (73.9%). The most common tumor subtype was the luminal B subtype as many 21 patients (45.7%). In conclusion, most patients of breast cancer with bone metastasis were 40-49 years old, invasive carcinoma of no special type, molecular subtype of luminal B, and no significant difference between lateralization to the right and left breast.Keywords: breast cancer, bone, metastasis, clinicopathological caharacteristics Abstrak: Kanker payudara merupakan jenis kanker yang paling sering dijumpai pada wanita.

Jenis penelitian ialah deskriptif dengan desain potong lintang. Sampel penelitian ialah 46 pasien kanker payudara dengan metastasis tulang yang tercatat di RSUP Sanglah tahun 2014-2018. Data diambil dari arsip hasil pemeriksaan patologi di Subdivisi Bedah Onkologi, Departemen/Kelompok Staf Medis (KSM) Bedah Fakultas Kedokteran Universitas Udayana (FK UNUD)/RSUP Sanglah untuk mendapatkan karakteristik klinikopatologi pasien kanker payudara metastasis tulang berdasarkan usia, lateralisasi, tipe histopatologik, dan subtipe molekuler tumor. Hasil penelitian menunjukkan kasus terbanyak terjadi pada rentang usia 40-49 tahun sebanyak 21 orang (45,7%), dengan lateralisasi tidak jauh berbeda antara payudara kanan sebanyak 22 orang (47,8) dan kiri sebanyak 23 orang (50%). Tipe histopatologik yang lebih sering ditemukan yaitu invasive carcinoma of no special type sebanyak 34 orang (73,9%). Subtipe molekuler yang paling banyak ditemukan ialah subtipe luminal B sebanyak 21 orang (45,7%). Simpulan penelitian ini pasien kanker payudara dengan metastasis tulang berada pada rentang usia 40-49 tahun, invasive carcinoma of no special type, subtipe molekuler luminal B. dan lateralisasi payudara kanan dan kiri tidak jauh berbeda.Kata kunci: kanker payudara, metastasis, tulang, karakteristik klinikopatologik

BackgroundMetastatic breast cancer (MBC) is a highly heterogeneous disease and bone is one of the most common metastatic sites. This retrospective study was conducted to investigate the clinical features, prognostic factors and benefits of surgery of breast cancer patients with initial bone metastases.MethodsFrom 2010 to 2015, 6,860 breast cancer patients diagnosed with initial bone metastasis were analyzed from Surveillance, Epidemiology, and End Results (SEER) database. Univariate and Multivariable analysis were used to identify prognostic factors. A nomogram was performed based on the factors selected from cox regression result. Survival curves were plotted according to different subtypes, metastatic burdens and risk groups differentiated by nomogram.ResultsHormone receptor (HR) positive/human epidermal growth factor receptor 2 (HER2) positive patients showed the best outcome compared to other subtypes. Patients of younger age (<60 years old), white race, lower grade, lower T stage (<=T2), not combining visceral metastasis tended to have better outcome. About 37% (2,249) patients received surgery of primary tumor. Patients of all subtypes could benefit from surgery. Patients of bone-only metastases (BOM), bone and liver metastases, bone and lung metastases also showed superior survival time if surgery was performed. However, patients of bone and brain metastasis could not benefit from surgery (p = 0.05). The C-index of nomogram was 0.66. Cutoff values of nomogram point were identified as 87 and 157 points, which divided all patients into low-, intermediate- and high-risk groups. Patients of all groups showed better overall survival when receiving surgery.ConclusionOur study has provided population-based prognostic analysis in patients with initial bone metastatic breast cancer and constructed a predicting nomogram with good accuracy. The finding of potential benefit of surgery to overall survival will cast some lights on the treatment tactics of this group of patients.

20033 Background: The purpose of this study was detection and expression profiling of circulating tumor cells (CTC) in breast cancer patients. Methods: Two separate probes of 5 mL peripheral EDTA-blood from patients with primary breast cancer (n=167) and metastatic disease (n=111) were used for immunomagnetic tumor cell selection. Targets for preanalytical enrichment were the antigens EpCAM and MUC-1. Separated cells were lysed and used for mRNA isolation and c-DNA synthesis. The breast carcinoma-associated transcripts EpCAM, MUC-1, HER-2, claudin7, cytokeratin 19, mammaglobin 1, prostate-specific ets factor (PSE) and survivin were amplified by three separate multiplex RT-PCR reactions. Amplicons were analysed by capillary electrophoresis with the Agilent Bioanalyzer 2100. Specificity of the RT-PCR was confirmed by examination of blood of healthy donors. Results: Sensitivity for every single transcript was adjusted to 2 tumor cells per 5 ml blood. Tumor-associated transcripts were detected in 31 of of 167 (18.5%) patients with primary breast cancer and in 46 of 111 (41%) patients with metastatic disease. The marker with the highest incidence in both groups was MUC-1, with a positivity rate of 81%. Tumor-associated transcripts were heterogenouosly expressed, however multiple markers were identified in more than 50% of the positive samples. Conclusion: Using a combination of preanalytical immunomagnetic tumor cell enrichment followed by a multigen RT-PCR approach we describe a sensitive detection system for breast carcinoma cells. In this study a panel of 8 genes overexpressed at high levels in metastatic breast cancer was selected for the identification of disseminated tumor cells in the peripheral blood of breast cancer patients. HER-2, survivin as a unique member of the inhibitor of apotosis protein family, as well as PSE identified in circulating breast cancer cells may serve as prognostic indicators of tumor progression and could represent valid targets for new individualized therapeutic interventions.
