Objectives : Most of pains are important symptoms caused by cancer transpered to spine. Harpagophyti Radix Pharmacopuncture is highly effective in reducing fever, pain, inflammation but was never used to reduce pain from cancer transpered to spine. So I intended to use Harpagophyti Radix Pharmacopuncture to control pain. The purpose of this study is to evaluate the clinical application of Harpagophyti Radix Pharmacopuncture for Bone Metastasis of Breast Cancer and Spinal Stenosis. Methods : We examined patient with Bone Metastasis of Breast Cancer and Spinal Stenosis who admitted Jaseng Korean Medicine Hospital. The patient was treated by Korean Medicine treatment and Harpagophyti Radix Pharmacopuncture. This case was assessed by Numerical Rating Scale(NRS), Oswestry Low Back Pain Disability Index(ODI), Short-Form 36 Health Survey(SF-36), ROM(Range of Movement) and Special Test. Results : In this study, the patient's pain was controlled and NRS, ODI were decreased. I could identify the improvement in life quality from the positive change of SF-36 and also found out that treatment was successful from the improvement of ROM, Special test. Conclusions : Harpagophyti Radix Pharmacopuncture with Korean Medicine treatment for Bone Metastasis of Breast Cancer and Spinal Stenosis was proved to be useful to the pain relief and function recovery, but further research should take place for clear understanding of the exact amount of dosage and safety. Moreover it must be accompanied by long term follow up research.

Background: This study investigated the survival benefit of radiotherapy (RT) of the supra- and infraclavicular lymphatic drainage area in Chinese women with T1-2N1M0 breast cancer receiving mastectomy. Methods: A total of 593 cases were retrospectively reviewed from 1998 to 2007. The relationship between supra- or infraclavicular fossa relapse (SCFR) and post-operative RT at the supra-/infraclavicular lymphatic drainage area was evaluated. Results: The majority of patients (532/593; 89. 8%) received no RT while 61 patients received RT. The median follow-up was 85 months. Among patients without RT, 54 (10. 2%) developed recurrence in the chest wall or ipsilateral SCFR. However, none of the 61 patients who underwent RT demonstrated SCFR. One patient who received RT (1. 6%) experienced recurrence in the chest wall. Univariate analysis revealed that age and molecular subtype (both P < 0. 05) were two prognostic factors related to supraclavicular and infraclavicular fossa relapse-free survival (SFRFS). Multivariate analysis revealed that only Her-2 positive status (P = 0. 011) was an independent predictor of SFRFS. RT had no influence on distant metastasis (P = 0. 328) or overall survival (P = 0. 541). SCFR significantly affected probability of distant metastasis (P < 0. 001) and overall survival (P < 0. 001). Conclusion: Although RT was not significantly associated with SFRFS, postoperative RT was significantly associated with a lower locoregional (i. e., supraclavicular/infraclavicular and chest wall) recurrence rate. SCFR significantly influenced distant metastasis-free survival, which significantly influenced the overall survival of T1-2N1M0 breast cancer patients after mastectomy. Thus, prophylactic RT is recommended in T1-2N1M0 breast cancer patients, especially those who have Her-2 positive lesions.

Purpose: This study was a retrospective analysis with survey study which analyze influence of depression of patients with cancer on metastasis. Methods: The subjects of this research were 223 patients who underwent chemotherapy or are in follow-up management with stomach, colon, or breast cancer. The questionnaires were collected in 2002 and medical documents were reviewed 400 days after the first data collection. Subjects were divided according to the depression level into over-average group and under average group. Results: In survival analysis, metastasis occurred in 49 of 211 in 223 subjects for whom follow-up review was done after 400 days. The depression and anxiety level were higher in the group with metastasis than the other with no metastasis. As a result, it showed that the lower depression they have, the lesser the metastasis occurred. Conclusion: This research showed that patients who have higher level of depression, experienced higher risk for cancer metastasis. Nurses who take care of cancer patients are responsible for giving patients with positivity with intention to subside their depression.

Breast cancer causes death due to distant metastases in which tumor cells produce matrix metalloproteinase (MMP) enzymes which facilitate invasion. Oleuropein, the main olive oil polyphenol, has anti-proliferative effects. This study aimed to investigate the effect of oleuropein on the metastatic and anti-metastatic gene expression in the MDA human breast cancer cell line. We evaluated the MMPs and TIMPs gene expression by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) in treated and untreated cells. This study demonstrated that OL may induce anti-metastatic effects on human breast cancer cells. We found that TIMP1,-3, and -4 were over-expressed after all periods of incubation in treated cancer cells compared to untreated cells, while MMP2 and MMP9 genes were down-regulated, at least initially. Treatment of breast cancer cells with oleuropein could help in prevention of cancer metastasis by increasing the TIMPs and suppressing the MMPs gene expressions.

Detection of micrometastasis in sentinel lymph nodes (SLNs) is a very useful tool for appropriate assessment of the clinical stage of disease in breast cancer patients. Early identification of clinically relevant disease could lead to early treatment or staging approaches for breast cancer patient. Micrometastases in SLNs of women with invasive breast cancer are of great significance in this context. In this study we examined SLN biopsies considered to have small numbers of cancerous cells by real time RT-PCR. All of the samples underwent immunohistochemical staining for cytokeratin for confirmation of the presence or absence of micrometastases. BUB1b expression assay of selected patients with and without metastasis showed overexpression in the former, but not in normal breast and lymph node tissue. Our results may be taken into account in the discussion about the merits of routine use of molecular assessment in pathogenetic studies of SLNs.

Background: Coptisine, an isoquinoline alkaloid extracted from Coptidis rhizoma, has many biological activities such as antidiabetic, antimicrobial and antiviral actions. However, whether coptisine exerts anti-cancer metastasis effects remains unknown. Materials and Methods: Effects of coptisine on highly metastatic human breast cancer cell MDA-MB-231 proliferation were evaluated by trypan blue assay and on cell adhesion, migration and invasion by gelatin adhesion, wound-healing and matrigel invasion chamber assays, respectively. Expression of two matrix metalloproteinases (MMPs), MMP-9, MMP-2 and their specific inhibitors tissue inhibitor of metalloproteinase 1 (TIMP-1) and tissue inhibitor of metalloproteinase 2 (TIMP-2) were analyzed by RT-PCR. Results: Coptisine obviously inhibited adhesion to an ECM-coated substrate, wound healing migration, and invasion through the matrigel in MDA-MB-231 breast cancer cells. RT-PCR revealed that coptisine reduced the expression of the ECM degradation-associated gene MMP-9 at the mRNA level, and the expression of TIMP-1 was upregulated in MDA-MB-231 cells, while the expression of MMP-2 and its specific inhibitor TIMP-2 was not affected. Conclusions: Taken together, our data showed that coptisine suppressed adhesion, migration and invasion of MDA-MB-231 breast cancer cells in vitro, the down-regulation of MMP-9 in combination with the increase of TIMP-1 possibly contributing to the anti-metastatic function. Coptisine might be a potential drug candidate for breast cancer therapy.

Breast cancer is the leading cause of cancer-related death in women worldwide, despite medical and technological advancements. The RhoBTB family consists of three isoforms: RhoBTB1, RhoBTB2, and RhoBTB3. RhoBTB1 and RhoBTB2 have been proposed as tumor suppressors in breast cancer. However, the roles of RhoBTB3 proteins are unknown in breast cancer. Bioinformatics analysis, including Oncomine, cBioportal, was used to evaluate the potential functions and prognostic values of RhoBTB3 and Col1a1 in breast cancer. qRT-PCR analysis and immunoblotting assay were performed to investigate relevant expression. Functional experiments including proliferation assay, invasion assay, and flow cytometry assay were conducted to determine the role of RhoBTB3 and Col1a1 in breast cancer cells. RhoBTB3 mRNA levels were significantly up-regulated in breast cancer tissues as compared to in adjacent normal tissues. Moreover, RhoBTB3 expression was found to be associated with Col1a1 expression. Decreasing RhoBTB3 expression may lead to decreases in the proliferative and invasive properties of breast cancer cells. Further, Col1a1 knockdown in breast cancer cells limited the proliferative and invasive ability of cancer cells. Knockdown of RhoBTB3 may exert inhibit the proliferation, migration, and metastasis of breast cancer cells by repressing the expression of Col1a1, providing a novel therapeutic strategy for treating breast cancer.

Background: Breast cancer is a heterogeneous disease with molecular subtypes that have biological distinctness and different behavior. They are classified into luminal A, luminal B, Her-2 and triple negative/basal-like molecular subtypes. Most of breast cancers reported in Indonesia are already large size, with high grade or late stage but the clinicopathological features of different molecular subtypes are still unclear. They need to be better clarified to determine proper treatment and prognosis. Aim: To elaborate the clinicopathological features of molecular subtypes of breast cancers in Indonesian women. Materials and Methods: A retrospective cross-sectional study of 84 paraffin-embedded tissues of breast cancer samples from Dr. Sardjito General Hospital in Central Java, Indonesia was performed. Expression of ER, PR, Her-2 and Ki-67 was analyzed to classify molecular subtypes of breast cancer by immunohistochemistry. The relation of clinicopathological features of breast cancers with molecular subtypes of luminal A, luminal B, Her-2 and triple negative/basal-like were analyzed using Pearson's Chi-Square test. A p-value of <0.05 was considered statistically significant. Results: Case frequency of luminal A, Luminal B, Her-2+ and triple negative/basal-like subtypes were 38.1%, 16.7%, 20.2% and 25%, respectively. Significant difference was found in breast cancer molecular subtypes in regard to age, histological grade, lymph node status and staging. However it showed insignificant result in regard to tumor size. Luminal A subtype of breast cancer was commonly found in >50 years old women (p:0.028), low grade cancer (p:0.09), negative lymph node metastasis (p:0.034) and stage III (p:0.017). Eventhough the difference was insignificant, luminal A subtype breast cancer was mostly found in small size breast cancer (p:0.129). Her-2+ subtype breast cancer was more commonly diagnosed with large size, positive lymph node metastasis and poor grade. Triple negative/basal-like cancer was mostly diagnosed among <50 years old women. Conclusions: This study suggests that immunohistochemistry-based subtyping is essential to classify breast carcinoma into subtypes that vary in clinicopathological features, implying different therapeutic options and prognosis for each subtype.

Cathepsin D is a protease which is known to facilitate invasion and metastasis of breast carcinoma. Overexpression of cathepsin D is associated with poor clinical outcome and biologic aggressiveness of the breast cancer. We underwent immunocytochemical assay(ICA) for cathepsin D in fine needle aspiration cytology(FNAC) specimens from the breast carcinoma and benign breast diseases. In FNAC specimens cathepsin D was expressed in 21(42.9%) out of 49 cases of invasive ductal carcinoma, whereas negative result was observed in all 15 cases of benign breast diseases including 7 fibroadenomas, 6 fibrocystic diseases, and 2 benign ductal hyperplasias. Among the 11 FNAC specimens from ductal carcinoma in situ(DCIS), cathepsin D was expressed in 3 cases(27.3%). In FNAC specimens immunocytochemistry for cathepsin D showed positive result in 24 out of 60 carcinomas(sensitivity, 40%) and negative result in 15 out of all 15 benign breast diseases(specificity, 100%). No significant correlation was noted between cathepsin D expression in FNAC specimen and clinicohistological characteristics of the breast carcinoma, such as hormone receptors and cell differentiation. In conclusion, ICA of cathepsin D in FNAC specimens thought to be a good adjunct to differentiate malignancy from benign breast diseases.

Osteopontin (OPN) is an integrin-binding protein, believed to be involved in a variety of physiological cellular functions. The physiology of OPN is best documented in the bone where this secreted adhesive glycoprotein appears to be involved in osteoblast differentiation and bone formation. In our study, we used semi-quantitative RT-PCR of osteopontin in calcification tissue of breast to detect breast cancer metastasis. The obtained data indicate that the expression of osteopontin is related to calcification tissue of breast, and possibly with the incidence of breast cancer. The expression strength of OPN by RT-PCR detection was related to the degree of malignancy of breast lesions, suggesting a close relationship between OPN and breast calcification tissue. The results revealed that expression of OPN mRNA is related to calcification of breast cancer tissue and to the development of breast cancer. Determination of OPN mRNA expression can be expected to be a guide to clinical therapy and prediction of the prognosis of breast cancer patients.
