Breast cancer is the most common malignant neoplasm among women. Metastases to the thyroid are relatively rare. Those lesions annunciate neoplasm dissemination in most cases. Metastatic breast cancer of thyroid lobe regrowth hasn’t been described yet. In the article the authors present a case of a 66-year old women with isolated, metachronous breast cancer metastasis in regrowth of the right thyroid lobe. Resection of the right lobe with metastatic tumor was performed with a purpose of total recovery. Despite surgery, multiple bone metastases were detected a few months after. In conclusion, regrowth of the thyroid is a potential site of recurrence and metastasis. Therefore, the thyroid bed cannot be omitted in routine examination during and after oncological treatment.

Cancer metastasis to the oral and maxillofacial region is uncommon, and metastasis to the mandibular condyle is considered rare. We present a case of a 56-year-old woman with a history of invasive ductal cell carcinoma of the right breast, 10 years in remission, presenting with a 6-month history of symptoms typical of temporomandibular joint (TMJ) dysfunction. Imaging revealed an osteolytic lesion of her right TMJ and subsequent open biopsy confirmed the diagnosis of metastatic breast cancer. Despite the rarity of metastatic cancer to the head and neck region, it is still important for clinicians from both medical and dental backgrounds to consider this differential diagnosis, particularly in patients with a history of hormonal positive subtype of breast cancer. Given that bony metastasis can manifest even 10 years after initial diagnosis, surveillance which includes examination of the head and neck region is important, and may include routine plain-film imaging surveillance with an orthopantomogram (OPG).

Breast cancer is the most frequent malignancy for women in which one in eight women will be diagnosed with the disease in their lifetime. Despite advances made in treating primary breast cancer, there is still no effective treatment for metastatic breast cancer. Consequently, metastatic breast cancer is responsible for 90% of breast cancer-related deaths while only accounting for approximately one third of all breast cancer cases. To help develop effective treatments for metastatic breast cancer, it is important to gain a deeper understanding of the mechanisms by which breast cancer metastasizes, particularly, those underlying organotropism towards brain, bone, and lungs. In this review, we will primarily focus on the roles that circulating exosomal microRNAs (miRNAs) play in organotropism of breast cancer metastasis. Exosomes are extracellular vesicles that play critical roles in intercellular communication. MicroRNAs can be encapsulated in exosomes; cargo-loaded exosomes can be secreted by tumor cells into the tumor microenvironment to facilitate tumor–stroma interactions or released to circulation to prime distant organs for subsequent metastasis. Here, we will summarize our current knowledge on the biogenesis of exosomes and miRNAs, mechanisms of cargo sorting into exosomes, the exosomal miRNAs implicated in breast cancer metastasis, and therapeutic exosomal miRNAs.

174 Background: It is generally accepted that patients with breast cancer metastases have poor survival. Metastatic breast cancer patients can be considered a heterogeneous population with a varied clinical course, which underscores the need for accurate prediction of survival based on prognostic factors. The purpose of the present study was to identify factors related to survival in breast cancer patients after diagnosis with metastatic disease. Methods: A total of 557 patients with breast cancer metastasis diagnosis seen at one large urban practice have been followed up between January 1, 1999 and June 30, 2008. Demographic, tumor characteristics, clinical factors as predictors of survival were analyzed using Cox regression model. Results: The median survival length was 40 months (range 1-114 months) with 269 (48.3%) alive and 288 (51.7%) dead. This study demonstrated that hypertension, estrogen receptor (ER) and/or progesterone receptor (PR) status, human epidermal growth factor receptor-2 (HER2) status, number of metastatic sites, and body mass index (BMI) at diagnosis with metastatic breast cancer were the most relevant prognostic factors for survival after metastasis. Conclusions: Findings of this study may form a foundation for the corpus of knowledge explaining the outcome differences in treatment of patients with metastatic breast cancer, potentially helping to create tailored counseling and personalized treatment approaches for this vulnerable group.

: The final stage of breast cancer involves spreading breast cancer cells to the vital organs like the brain, liver lungs and bones in the process called metastasis. Once the target organ is overtaken by the metastatic breast cancer cells, its usual function is compromised causing organ dysfunction and death. Despite the significant research on breast cancer metastasis, it’s still the main culprit of breast cancer-related deaths. Exploring the complex molecular pathways associated with the initiation and progression of breast cancer metastasis could lead to the discovery of more effective ways of treating the devastating phenomenon. The present review article highlights the recent advances to understand the complexity associated with breast cancer metastases, organotropism and therapeutic advances.

Abstract Epidermal growth factor receptor (EGFR) is commonly over-expressed in metastatic breast cancer yet metastatic breast cancer is generally resistant to anti-EGFR therapies, and the mechanism for resistance to EGFR inhibitors in this setting is not fully understood. Hormonally up-regulated neu-associated kinase (HUNK) kinase is up-regulated in aggressive breast cancers and is thought to play a role in breast cancer metastasis. However, no studies have been conducted to examine a relationship between EGFR and HUNK in breast cancer metastasis. We performed a kinase substrate screen and identified that EGFR is phosphorylated by HUNK. Our studies show that HUNK phosphorylates EGFR at T654, enhancing receptor stability and downstream signaling. We found that increased phosphorylation of T654 EGFR correlates with increased epithelial to mesenchymal, migration and invasion, and metastasis. In addition, we found that HUNK expression correlates with overall survival and distant metastasis free survival. This study shows that HUNK directly phosphorylates EGFR at T654 to promote metastasis and is the first study to show that the phosphorylation of this site in EGFR regulates metastasis.

Metastatic features of breast cancer in the brain are considered a common pathology in female patients with late-stage breast cancer. Ca2+ signaling and the overexpression pattern of Ca2+ channels have been regarded as oncogenic markers of breast cancer. In other words, breast tumor development can be mediated by inhibiting Ca2+ channels. Although the therapeutic potential of inhibiting Ca2+ channels against breast cancer has been demonstrated, the relationship between breast cancer metastasis and Ca2+ channels is not yet understood. Thus, we focused on the metastatic features of breast cancer and summarized the basic mechanisms of Ca2+-related proteins and channels during the stages of metastatic breast cancer by evaluating Ca2+ signaling. In particular, we highlighted the metastasis of breast tumors to the brain. Thus, modulating Ca2+ channels with Ca2+ channel inhibitors and combined applications will advance treatment strategies for breast cancer metastasis to the brain.


The underlying mechanisms of metastasis in patients with breast cancer is still poorly understood. Approximately 6% of patients with breast cancer present with metastasis at the time of diagnosis. Metastatic breast cancer is difficult to treat and patients with breast cancer with distant metastasis have a significantly lower 5-year survival rate compared to patients with localised breast cancer (27% and 99%, respectively). During breast cancer progression, tumour cells first metastasise to nearby draining lymph nodes and then to distant organs, primarily bone, lungs, liver, and brain. In this brief review, the authors discuss breast cancer metastasis, the role of epithelial–mesenchymal transition and the contributions of the immune system to the metastatic process. The authors also briefly discuss whether there is any relationship between tumour size and metastatic potential, and recent advances in treatment for metastatic breast cancer. The studies highlighted suggest that immunotherapy may play a more significant role in future patient care for metastatic breast cancer.

AbstractConstitutively active estrogen receptor-α (ER/ESR1) mutations have been identified in approximately one third of ER+ metastatic breast cancer. Although these mutations are known mediators of endocrine resistance, their potential role in promoting metastatic disease has not yet been mechanistically addressed. In this study, we show the presence of ESR1 mutations exclusively in distant, but not local recurrences. In concordance with transcriptomic profiling of ESR1 mutant tumors, genome-edited Y537S and D538G cell models have a reprogrammed cell adhesive gene network via alterations in desmosome/gap junction genes and the TIMP3/MMP axis, which functionally confers enhanced cell-cell contacts while decreased cell-ECM adhesion. Context-dependent migratory phenotypes revealed co-targeting of Wnt and ER as vulnerability. Mutant ESR1 exhibits non-canonical regulation of several metastatic pathways including secondary transactivation and de novo FOXA1-driven chromatin remodeling. Collectively, our data supports evidence for ESR1 mutation-driven metastases and provides insight for future preclinical therapeutic strategies.SignificanceContext and allele-dependent transcriptome and cistrome reprogramming in genome-edited ESR1 mutation cell models elicit diverse metastatic phenotypes, including but not limited to alterations in cell adhesion and migration. The gain-of-function mutations can be pharmacologically targeted, and thus may be key components of novel therapeutic treatment strategies for ER-mutant metastatic breast cancer.

Introduction. Late metastases of malignant tumors in the temporal bone are very rare lesions. They can be asymptomatic for a long time, and usually manifest themselves in the form of hearing loss, dizziness, tinnitus, and paralysis of the facial nerve. Modern radiological diagnostics and explorative surgery with biopsy are essential for diagnosis. Case report. We present a rare and unusual case of a 66-year-old female patient with a facial nerve paralysis that appeared as the first sign of metastatic breast cancer in the temporal bone 10 years after treatment. A sudden hearing loss and dizziness occurred six months later and value of CA 15-3 was elevated. Scintigraphy pointed to susceptible metastatic deposits of the axial skeleton, without lesions in the temporal bone. Finally, repeated computerized tomography revealed osteolytic changes of the temporal bone six months after that. Immunohistochemical analysis of mastoid tissue samples confirmed that it was a breast cancer metastasis. One year after palliative radiotherapy and oral hormone therapy, a patient has a good general condition with better function of the facial nerve. Conclusion. A high degree of clinical suspicion sometimes requires repeated radiological diagnostics in order to detect osteolytic metastatic changes in the temporal bone, but also in other bone structures within the hematogenous dissemination of the malignant disease.

Background: Platelet-lymphocyte ratio (PLR) is known associated with the prognosis of distant metastatic breast cancer. Tumor-infiltrating lymphocyte (TIL) in breast cancer also associated with the prognosis of distant metastatic breast cancer. In this study, we will examine the relationship between PLR and TIL, in association with the metastatic incidence in breast cancer.Methods: This research is a retrospective, analytic, cross-sectional study. Data was taken from medical records of breast cancer patients at Sanglah general hospital. Samples were taken by nested sampling by selecting all breast cancer patients from the period of January 1st, 2017, to December 31st, 2018, which had complete medical record data, with total sample 211. The PLR and TIL were calculated and analyzed in relation to metastasis incidence of breast cancer.Results: The sample characteristics were sorted by age, education, occupation, the area of origin, menstrual status, breast cancer staging, breast cancer subtype, TIL levels, lymphovascular invasion (LVI) status, metastatic status, and breast cancer grading. The data were analyzed to know the association of PLR, TIL, confounding factors in relation to metastatic incidences. In the sample group with PLR ≥ 156 10µ /µL, there were 22.9% cases of metastases (p = 0.002). The sample group at low TIL had metastatic event 12.5% with (p=0.442).Conclusions: PLR was associated with higher metastasis in breast cancer patients and low TIL had no association with breast cancer metastasis.
