Background. Breast cancer is one of the most diagnosed cancer in the world. Breast cancer starts when the breast cell grows abnormally and turns malignant. In Indonesia, breast cancer is the most diagnosed cancer in women. Up to now, the cause of breast cancer has not been identified yet. There are many factors that increase the risk of breast cancer, one of them is the early age of menarche. Objective. This study aims to obtain characteristics of breast cancer patients based on age of menarche in RSUP Haji Adam Malik in 2014-2017. Method. The study was designed in observational with descriptive method. The sampling had been done using total sampling technique. Results. Based on general characteristics, the majority of breast cancer patients are in the range of 40-49 years old (38,5%), graduated high school (45,2%), unemployed (66,3%), and do not have family history (94,2%). Majority of patients have stadium IIIB breast cancer (41,3%). The most diagnosed histopathology is Invasive Ductal Carcinoma (78,8%). Majority of breast cancer patients have negative estrogen receptor (67,3%), negative progesterone receptor (67,3%), negative her2 (66,3%) and positive ki-67 (67,3%). Fifty three breast cancer patients (51%) have early menarche. Based on the age of menarche, the patient with early menarche mostly has stage three breast cancer, but the age of menarche does not give a specific characteristic in histopathology and immunohistochemistry. Conclusion. Age of menarche gives specific characteristic in staging but not in histopathology and immunohistochemistry.

Introduction: Phyllodes tumors are fibroepithelial breast lesions that are uncommon in women and rare among children. Due to scarcity, there are only a few large pediatric phyllodes tumor series. Current guidelines do not differentiate treatment recommendations between children and adults.Case Presentation: A 12-year-old girl presented with a lump in her right breast which grew rapidly within a month. On physical examination, we found a mass on the right breast sized ± 10 x 10 cm; the lump was fragile and bled easily. The patient’s condition was getting worse and worse. Due to this deterioration, we performed a mastectomy immediately.Conclusions: The incidence of malignant phyllodes tumor in children is very rare and required prompt treatment in emergency cases.

Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer that does not have estrogen receptors, progesterone receptors, and HER-2 receptors. This subtype is found in 15-20% of all types of breast cancer, and it is often associated with a high recurrence rate and mortality after getting definitive therapy. The aim of our study is to investigate the clinicopathology of breast cancer in our center, where the majority were Bataknese.Methods: We evaluated the clinical and pathological characteristics of TNBC retrospectively from medical records data, from January 2017 to December 2019 with a total of 105 patients but only 79 patients had complete clinicopathological and immunohistochemistry data. This study was conducted in Murni Teguh Memorial Hospital, Medan, Indonesia. Results: From 79 TNBC patients, the average age at clinical presentation was 41-50 years group about 35 samples (44.3%). All patients had an invasive type of ductal carcinoma (100%). The majority of tumor size was T2 in 51 patients (64,6%), 83.6% grade 3 tumors. Both angioinvasion and lymph invasion were found in 48 patients (60.8%) while tumor-infiltrating lymphocyte (TIL) was found in 58 patients (73.4%), and 44 patients (55.7%) had lymph node metastases.Conclusions: According to some existing literature, TNBC showed more aggressive characteristics which are the same as our study. TNBC was diagnosed at young age, grade 3 tumors, having TIL which is very likely to occur distant metastases to lymph nodes.

Full‐thickness wound healing is a complex process requiring a well‐orchestrated mechanism of various factors, including cytokines, particularly interleukin (IL)‐10 and transforming growth factor (TGF)‐β. IL‐10 and TGF‐β act as robust anti‐inflammatory cytokines in accelerating the wound healing process by regulating myofibroblasts. Hypoxic mesenchymal stem cell‐conditioned medium (hypMSC‐CM) containing cytokines potentially contribute to accelerate wound repair without scarring through the paracrine mechanism. This study aims to observe the role of hypMSC‐CM in controlling TGF‐β and IL‐10 levels to accelerate full‐thickness wound repair and regeneration. A total of 24 male Wistar rats were used in this study. Six healthy rats as a sham group and 18 rats were created as full‐thickness‐wound animal models using a 6 mm punch biopsy. The animals were randomly assigned into three groups (n = 6) consisting of two treatment groups treated with hypMSC‐CM at a low dose (200 µL hypMSC‐CM with 2 g water‐based gel added) and a high dose (400 µL hypMSC‐CM with 2 g water‐based gel added) and a control group (2 g water‐based gel only). The IL‐10 and TGF‐β levels were examined by ELISA. The results showed a significant increase in IL‐10 levels on day 3 after hypMSC‐CM treatment, followed by a decrease in platelet‐derived growth factor (PDGF) levels on days 6 and 9. In line with this finding, the TGF‐β levels also increased significantly on day 3 and then linearly decreased on days 6 and 9. HypMSC‐CM administra‐ tion may thus promote wound healing acceleration by controlling IL‐10 and TGF‐β levels in a full‐thickness‐wound rat model.

Human epidermal growth factor receptor 2 (HER-2) is used as a marker for the diagnosis and prognosis of breast cancer. However, the molecular mechanisms involving HER2 in breast cancer require further study. Herein, we used the bioinformatics approaches to identify important pathways and hub genes in breast cancer affected by HER-2. The results showed that HER-2 is highly expressed in ovarian cancer and is closely related to the overall survival and progression-free survival of breast cancer. A total of 3014 downregulated genes and 4121 upregulated genes were identified under Gene Expression Omnibus (GEO) database with the GEO2R tool. Among them, the top 10 hub genes including CCNB1, KIF11, BUB1B, TOP2A, ASPM, MAD2L1, BUB1, RRM2, EGFR, and FN1 demonstrated by connectivity degree in the protein-protein interaction (PPI) network were screened out. In Kaplan–Meier plotter survival analysis, the overexpression of CCNB1, EGFR, MAD2L1, ASPM, and RRM2 were shown to be associated with an unfavourable prognosis in HER-2 positive breast cancer patients. In conclusion, we have identified important signalling pathways involving HER-2 that affect breast cancer. These findings could provide new insights outlining mechanisms involving HER-2 gene expression in breast cancer and provides a rationale for the novel treatment of breast cancer.

Background: Immune biologic markers that can predict clinical response to anti-PD-1/PD-L1 therapy are needed to identify and validate tumor immunotherapy studies. High PD-L1 expression is associated with increased clinical response in patients with various types of cancer treated with inhibitors of the PD-1/PD-L1 pathway. Objective: The researcher wanted to see the clinicopathological characteristics of invasive breast carcinoma according to the immunohistochemical expression of PD-L1. Methods: This study is a descriptive study with a cross-sectional, retrospective approach by looking at secondary data from the medical records of the Department of Surgery, Haji Adam Malik Hospital from January 1, 2019, to December 31, 2021. Results: Immunohistochemical expression of PD- L1 was positive in 76.6% of invasive breast carcinomas and negative in 23.3% of invasive breast carcinomas. Immunohistochemical expression of PD-L1 was positive in non-specific IBCs that predominated in every molecular subgroup of breast carcinoma. Conclusion: Tumours can show positive or negative PD-L1 expression through several biological processes with different functional significance, namely the genetic mechanism of constitutive or oncogene-induced PD-L1 expression, PD-L1 expression induced in T cells, and absence of PD-L1 expression. Due to the absence of T cells and genetic events that block the expression of PD-L1 despite T cell infiltration.

Background: Breast cancer is the most frequently diagnosed cancer in the world. Breast cancer occurs due to abnormal cell growth in breast tissue so that it becomes malignant. In Indonesia, breast cancer is the most common cancer in women. That way, many markers are needed as prognostic and predictive of breast cancer. One of the prognostic factors for breast cancer is neutrophil levels combined with clinicopathological factors. Objective: Knowing the clinicopathology of breast cancer based on neutrophil levels at the Adam Malik Medan General Hospital in 2018-2021. Methods: The research design is observational with a descriptive method and calculated using the Lemeshow formula. Results: Majority aged 40-49 years (39.6%), high school (44.8%), housewives (67.7%), no family history (97.9%), tumor grade II (38.5%) %), Tumor Infiltrating Lymphocytes (TILs) severe (47.9 %), mitotic score 1 (38.5 %), metastatic positive lymph node status (87.5 %), tumor size T1 (36.5 %), The number of positive and negative Estrogen Receptors is the same (50.0%), Progesterone Receptor is negative (56.3%), HER2 is 1+ (60.4%), Ki-67 is positive (84 .4 %), positive angioinvasion (63.5 %), Invasive Ductal Carcinoma (90.6 %), high neutrophil levels (77.1 %). Conclusion: High levels of neutrophils tend to result in severe Tumor Infiltrating Lymphocytes (TILs) which will increase tumor growth, occurrence of metastases, increased positive angioinvasion, negative Estrogen Receptor status, negative Progesterone Receptor status, HER2 1+ status, positive Ki-67 status.
