Purpose: This study aimed to investigate the factors of occurrence of amenorrhea and the severity of climacteric symptoms in breast cancer patients who underwent chemotherapy. Method: Women diagnosed with breast cancer without metastasis or recurrence, had surgery followed by chemotherapy, and had menses at the time of surgery were recruited from S hospital located in Seoul. A total of 99 women aged 31 thru 55 years participated and filled out a structured questionnaire including the Functional Assessment Cancer Therapy-Breast plus Endocrine Symptom when they visited the clinic for follow-up. Result: In 88 women amenorrhea occurred within an average of 2 months since beginning chemotherapy, and menstruation was resumed in only 11 women. About 98% of women aged over 40 experienced a cessation in menses thus age was an apparent factor of amenorrhea (Exp(B)=.76, p<.05). Presence of chronic disease (${\beta}=.25$, p<.05) and body weight change (${\beta}=.30$, p<.01) were significant factors influencing the severity of climacteric symptoms. Conclusion: Nurses need to have clinical evidences of menstrual changes due to breast cancer treatment. Information about premature menopause and climacteric symptoms should be provided according to women's health conditions so that they cope better during their survival.
Background/Aim: Pristimerin isolated from Celastrus and Maytenus spp can inhibit proteasome activity. However, whether pristimerin can modulate cancer metastasis is unknown. Methods: The impacts of pristimerin on the purified and intracellular chymotrypsin proteasomal activity, the levels of regulator of G protein signaling 4 (RGS 4) expression and breast cancer cell lamellipodia formation, and the migration and invasion were determined by enzymatic, Western blot, immunofluorescent, and transwell assays, respectively. Results: We found that pristimerin inhibited human chymotrypsin proteasomal activity in MDA-MB-231 cells in a dose-dependent manner. Pristimerin also inhibited breast cancer cell lamellipodia formation, migration, and invasion in vitro by up-regulating RGS4 expression. Thus, knockdown of RGS4 attenuated pristimerin-mediated inhibition of breast cancer cell migration and invasion. Furthermore, pristimerin inhibited growth and invasion of implanted breast tumors in mice. Conclusion: Pristmerin inhibits proteasomal activity and increases the levels of RGS4, inhibiting the migration and invasion of breast cancer cells.
Secreted protein acidic and rich in cysteines-like protein 1 (SPARCL1), an extracellular matrix glycoprotein, has been implicated in the pathogenesis of several disorders including cancer. However, little is known about the expression and significance of SPARCL1 in human breast cancer. The aim of this study was to determine the expression pattern and clinicopathological significance of SPARCL1 in a Chinese breast cancer cohort. mRNA and protein expression of SPARCL1 in human breast cancer cell lines and breast cancer tissues was detected using the reverse transcription-polymerase chain reaction, real-time quantitative PCR, and Western blotting, respectively. Immunostaining of SPARCL1 in 282 Chinese breast cancer samples was examined and associations with clinicopathological parameters were analyzed. Compared to the positive expression in immortalized human breast epithelial cells, SPARCL1 was nearly absent in human breast cancer cell lines. Similarly, a significantly reduced expression of SPARCL1 was observed in human breast cancer tissues compared to that in normal breast epithelial tissues, for both mRNA and protein levels (P < 0.001). Immunohistochemical analysis showed that strong cytoplasmic immunostaining of SPARCL1 was observed in almost all normal breast samples (43/45) while moderate and strong immunostaining of SPARCL1 was only detected in 191 of 282 (67.7%) breast cancer cases. Moreover, down-regulation of SPARCL1 was significantly correlated with lymphatic metastasis (P = 0.020) and poor grade (P = 0.044). In conclusion, SPARCL1 may be involved in the breast tumorigenesis and serve as a promising target for therapy of breast cancer.

Objective: To explore the expression and significance of estrogen receptor (ER), progestrone receptor (PR), vascular endothelial growth factor (VEGF), CA15-3, CA125 and carcinoma embryonic antigen (CEA) expression in judging the prognosis of breast cancer. Materials and Methods: Sixty-five patients with breast cancer undergoing operations in the general surgery department were considered as the observation group, and 50 healthy outpatients of our hospital as the control group. Cubital venous blood was drawn in the morning from fasting patients in the two groups and chemiluminescence immunoassays were used to detect the levels of CA15-3, CA125 and CEA in serum. The follow-up duration was from 4 months to 2 years, and change in levels of the indicators was detected by dynamically drawing blood. After surgery, cancer tissue samples of patients in observation group remained on file (the non-recurrent patients were biopsied). Immunohistochemistry was applied to determine the expression of ER, PR and VEGF in tissue. Results: The effective rate of 12 patients with negative ER and PR expression was 33.3% in the observation group, being associated with prognosis to varying extents. Serum CA15-3, CA125 and CEA in the observation group were all significantly higher than in control group (p<0.01). With increase in pathological staging, levels of serum CA15-3, CA125 and CEA gradually increased (p<0.01). Levels in patients with lymph node metastasis were markedly higher than in those without (p<0.01). In addition, values with distal lymph node metastasis were notably higher than with adjacent lymph node metastasis (p<0.01). The postoperative follow-up results revealed that positive VEGF and levels of serum VEGF, CA15-3, CA125 and CEA in recurrence group were obviously higher than in non-recurrence group (p<0.01). Conclusions: Joint detection of ER and PR expression as well as levels of serum VEGF, CA15-3, CA125 and CEA is meaningful and can guide the diagnosis and treatment for breast cancer.

Introduction: Breast cancer aggressiveness can be correlated with proliferation status of tumor cells, which can be ascertained with tumor grade and Ki67 indexing. However due to lack of reproducibility, the ASCO do not recommend routine use of Ki67 in determining prognosis in newly diagnosed breast cancers. We therefore aimed to determine associations of the Ki67 index with other prognostic markers like tumor size, grade, lymph node metastasis, ER, PR and HER2neu status. Methods: A total of 194 cases of newly diagnosed breast cancer were included in the study. Immunohistochemical staining for ER, PR, HER2neu and Ki67 was performed by the DAKO envision method. Associations of the Ki67 index with other prognostic factors were evaluated both as continuous and categorical variables. Results: Mean age of the patients was 51.7 years (24-90). Mean Ki67 index was 26.9% (1-90). ER, PR, HER2neu positivity was noted in 90/194 cases (46.4%), 74/194 cases (38.1%) and 110/194 cases (56.70%) respectively. Significant association was found between Ki67 and tumor grade, PR, HER2neu positivity and lymph node status, but no link was apparent with ER positivity and tumor size. There wasan inverse relation between Ki67 index and PR positivity, whereas a direct correlation was seen with HER2neu positivity. However, high Ki67 (>30%) was associated with decreased HER2neu positivity as compared to intermediate Ki67 (16-30%). The same trend was established with lymph node metastasis. Conclusion: Our study indicates that with high grade tumors, clinical utility of ki67 is greater in combination with other prognostic markers because we found that tumors with Ki67 higher than 30% have better prognostic profile compared to tumors with intermediate Ki67 level, as reflected by slightly lower frequency of lymph node metastasis and HER2neu expression. Therefore we suggest that Ki67 index should be categorized into high, intermediate and low groups when considering adjuvant chemotherapy and prognostic stratification.
The aim of this study is to evaluate clinicopathologic characteristics and the multi-disciplinary treatment results of metaplastic breast cancer (MBC) patients treated in a single institute. Seventeen female patients with MBC treated in our department between June 2000 and January 2012 were identified and retrospectively evaluated. The median age at diagnosis was 46 years (range, 26-66 years). The median tumor size at diagnosis was 3.5 cm (range 1.5-12 cm). Six (35%) patients underwent breast conservation surgery and 11 (65%) mastectomy. Axillary lymph node metastasis was found in 6 (35%) patients. Twelve (71%) had triple negative tumors. Postoperative RT and systemic adjuvant treatment was given to all patients accordingly to stage and biological characteristics. Median follow-up time was 27 months (range, 12-151 months). At the time of this analysis, 14 (82%) patients were alive with no evidence of disease, and 1 (6%) was alive with disease. The 3-year OS was 91% and 5-year 80%, and DFS rates were 76% and 76%, respectively. Despite the young age of our patients with mostly high grade tumors, larger tumor size and higher rates of lymph node metastasis, the survival outcomes in our study are favorable in comparison with previously reported series.
Purpose: This report compared the diagnostic effectiveness between ultrasmall superparamagnetic iron oxide (USPIO) and gadolinium (Gd) based magnetic resonance imaging (MRI) for differentiation of axillary status in breast cancer patients. Materials and Methods: The present authors performed a meta-analysis of previous studies that compared USPIO or Gd based MRI with histological diagnosis after surgery or biopsy. We searched PubMed, EMBASE, Cochrane Library, ScienceDirect, SpringerLink, Ovid databases and references of articles to identify studies reporting data until December 2013. Pooled sensitivity and specificity were calculated for every study; summary receiver operating characteristic and subgroup analysis was done. Analyses of study quality and heterogeneity were also assessed. Results: There were 14 publications that met the criteria for inclusion in our meta-analysis. USPIO based MRI showed 0.83 (95% CI: 0.75-0.89) and 0.97 (95% CI: 0.94-0.98) for pooled sensitivity and specificity, respectively. Gd based MRI represented pooled sensitivity and specificity of 0.61 (95% CI: 0.55-0.67) and 0.90 (95% CI: 0.87-0.92) for each. Overall weighted area under the curve for USPIO and Gd based MRI were 0.9563 and 0.9051, respectively. Conclusion: USPIO based MRI had a tendency toward high pooled sensitivity and specificity in detection of axillary metastases for breast cancer. This result may mean that USPIO based MRI could be used as complementary modality to differentiate axillary status more precisely, and assist in the decision-making process regarding possible invasive procedures, such as sentinel node biopsy.
Purpose : Among numerous biological symptoms of cancer, matrix metalloproteinases (MMPs) are essential for tumor invasion and metastasis. HAD is used as an inhibitor of MMP gene. This study was designed to evaluate the effects of HAD on anti metastasis and preventing recurrence in cancer patients. Materials and Methods : We retrospectively analyzed the medical records of 69 cancer patients who had been administered with HAD for over 12 months continuously in East-West Cancer Center of Oriental Hospital of Daejeon University, from January 1993 to May 2002. Results : We analyzed gender, portion, stage and anti-metastasis & recurrence rates of cancer patients. Analysis of sex cases showed that the percentage of male is 62.3%, female is 37.7%. Analysis of cancer portion showed that the percentage of stomach is 31.9%, colorectum is 26.1%, lung is 21.7%, liver is 8.7%, breast is 8.7% Analysis of stage showed that the rate of III is 78.3%, IV is 13.0% and II is 8.7%. Analysis of anti-metastasis and recurrence rates showed that colorectal cancer is 77.8%, stomach cancer is 63.6%, lung cancer is 33.4% and breast cancer is 33.3% (mean : 53.6%). Conclusions : HAD has significant effects on anti-metastasis and preventing recurrence of tumor on cancer patients. So it helps to prolong the survival rates of cancer patients.

Background: An association between alcohol/tobacco use and risk of metastasis in breast cancer has been clearly shown. Materials and Methods: The present study explored, in 48 samples of tissue from mammary ductal carcinoma (taken from Mexican women with an average age of $58.2{\pm}10.9$ years), the association of risk of metastasis with the status of hormonal receptors and the c-erbB2 protein (by immunohistochemistry) as well as clinical, histopathological and sociodemographic factors. Results: Of 48 patients, 41.6% (20/48) presented with metastasis, 43.8% were positive for the estrogen receptor (RE+), 31.3% for the progesterone receptor (RP+) and 47.7% for c-erbB2 (c-erbB2+). The following combinations were found: RE+/RP+/c-erbB2+ 8.3%, RE+/RP+ 22.9%, RE+/RP- 20.8%, RE-/RP+ 8.3%, RE-/RP-/c-erbB2- 22.9% and RE-/RP- 47.8%. There were 12 patients who used alcohol/tobacco, of which 91.6% did not present metastasis and 81.9% were RE-/RP-. Compared to the RE-/RP-/c-erbB2+, the RE+/RP+/c-erbB2+ group had a 15-fold greater risk for metastasis (95%CI, 0.9-228.8, p=0.05). The carriers of the double negative hormonal receptors had a 4.7 fold greater probability of being (or having been) smokers or drinkers (95%CI, 1.0-20.4, p = 0.03). Conclusions: There was a clear protective effect of using alcohol and/or tobacco, in the cases included in the present study of mammary ductal carcinoma, associated with double negative hormonal receptors. However, this association could be due to a protective factor not measured (Neyman bias) or to a bias inherent in the rate of hospitalization (Berkson fallacy). This question should be explored in a broad prospective longitudinal study.
This report is aimed to investigate the effect of Integrative Medicine Therapy (IMT) in treating breast cancer metastasized to several portion. A 55-year-old woman who was diagnosed breast cancer and treated by breast conservation surgery (BCS) IN 2002. (pT2M0N0), adjuvant chemotherapy and radiotherapy till Jan. in 2013. But cancer had metastasized to sacrum (2009), liver (2012) and ribs (2013). Finally cause of several side effects of Xeloda(neuralgia and vommiting), she gave up to be treated by Xeloda and started to receive IMT including Abnoba Viscum, Vitamin C therapy Xeloda again, Korean herbal medicine and pharmacopuncture from Jul. in 2013. The effect was evaluated with Positron Emission Tomography and Computed Tomography (PET-CT) and Abdomen Computed Tomography (CT). The metastatic tumor in liver was disappeared and cancers to ribs, their size decreased after 12 months and pain of sacrum maintained VAS 2 continually. These results suggest that IMT is a therapeutic method to treat metastatic tumor originated from breast cancer.
