Purpose: The purpose of this study was to investigate the effects of a rehabilitation program on physical health, physiological indicators and quality of life in breast cancer mastectomy patients. Methods: The subjects included thirty-one patients with breast cancer(17 in the experimental group and 14 in the control group). The subjects in the experimental group participated in a rehabilitation program for 10 weeks, which was composed of an exercise program, teaching, counseling and support for 2 sessions per week. Results: There was a significant increase in flexion, internal rotation and external rotation but no significant increase in extension in the experimental group compared to the control group. The total cholesterol, triglyceride, HDL, LDL, and CD56 in the experimental group compared to the control group was not significantly decreased after the rehabilitation program. Compared to the control group, quality of life in the experimental group was significantly improved and fatigue in that group was significantly decreased after the rehabilitation program. Conclusion: The 10-week rehabilitation program showed a large affirmative effect on physical health, physiological indicators and quality of life in breast cancer mastectomy patients.

Introduction: Breast cancer is the second leading cancer in Korean women. To assess potential genetic associations between the prostate stem cell antigen (PSCA) gene in the chromosome 8q24 locus and breast cancer risk in Korean women, 13 SNPs were selected and associations with breast cancer risk were analyzed with reference to hormone receptor (HR) and menopausal status. Methods:We analyzed DNA extracted from buffy coat from 456 patients and 461 control samples, using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) based upon region-specific PCR followed by allelespecific single base primer extension reactions. Risks associated with PSCA genotypes and haplotypes were estimated with chi-square test (${\chi}^2$-test), and polytomous logistic regression models using odds ratios (OR) and 95% confidence intervals (CIs), by HR and menopausal status. Results: In case-control analysis, odds ratios (OR) of rs2294009, rs2294008, rs2978981, rs2920298, rs2976395, and rs2976396 were statistically significant only among women with estrogen receptor (ER) negative cancers, and those of rs2294008, rs2978981, rs2294010, rs2920298, rs2976394, rs10216533, and rs2976396 were statistically significant only in pre-menopausal women, and not in postmenopausal women. Risk with the TTGGCAA haplotype was significantly elevated in ER (-) status (OR= 1.48, 95% CI= 1.03~2.12, p<0.05). Especially risk of allele T of rs2294008 is significantly low in pre-menopausal breast cancer patients and AA genotype of rs2976395 in ER (-) status represents the increase of OR value. Conclusion: This report indicated for the first time that associations exist between PSCA SNPs and breast cancer susceptibility in Korean women, particularly those who are pre-menopausal with an estrogen receptor negative tumor status.

Background: The purpose of this study was to identify predictive factors for supraclavicular lymph node recurrence (SCLR) in N1 breast cancer patients and define a high-risk subgroup who might benefit from supraclavicular nodal radiotherapy (RT). Materials and Methods: From January 1995 to December 2009, 113 breast cancer patients with 1 to 3 positive axillary lymph nodes were enrolled in this study. All patients underwent breast-conserving surgery (BCS) or modified radical mastectomy (MRM). RT was given to all patients who received BCS. Among the patients given MRM, those with breast tumors >5 cm in size received RT. Regional nodal irradiation was not applied. Systemic chemotherapy was given to 105 patients (92.9%). Patient data were retrospectively reviewed and analyzed to identify predictive factors for SCLR. Results: The median follow-up duration was 6.5 years, with 5- and 10-year actuarial SCLR rates of 9.3% and 11.2%, respectively. Factors associated with SCLR on univariate analysis included histologic grade, number of dissected axillary lymph nodes, lymphovascular invasion, extracapsular extension (ECE), and adjuvant chemotherapy. On multivariate analysis, histologic grade and ECE remained significant. The patient group with grade 3 and ECE had a significantly higher rate of SCLR compared with the remainder (5-year SCLR rate; 71.4% vs. 4.0%, p<0.001). Conclusions: Histologic grade and ECE status are significant predictive factors for SCLR. Supraclavicular nodal RT is necessary in N1 breast cancer patients featuring histologic grade 3 and ECE.

In order to develop as a natural source of anticancer materials of Cudrania tricuspidata, the cytotoxicity of methanol extracts by harvesting parts and times against 8 cell lines including 293 (normal kidney cells) and A-431 (epidermoid carcinoma cells) were investigated using MTT assay. All harvesting parts had hardly cytotoxicity against 293. And methanol extracts of stem bark and root bark showed very high cytotoxicities against 7 cancer cell lines. The cytotoxicity was the highest against HeLa (cervix adenocarcinoma cells) and followed by MCF-7 (breast adenocarcinoma cells), AGS (stomach adenocarcinoma cells), HT-29 (colon adenocarcinoma cells), HepG2 (hepatoblastoma cells), A549 (lung carcinoma cells) and A-431. By the way, leaf extract had a cytotoxicity against only AGS and ripe fruit extract had no cytotoxicity. Among harvesting times, the cytotoxicity of root bark were high from April to September but that of stem bark showed a little difference. These results showed that anticancer activities of Cudrania tricuspidata extracts were eventful changes by harvesting parts and times.

In order to find out anticancer activity of Korean pepper (Capsicum annuum L.), the cytotoxicity against 8 cell lines including 293 (normal kidney cells) and A-431 (epidermoid carcinoma cells) of extracts by extraction solvents and plant parts were investigated using MTT assay. Also the correlation between content of capsaicin known as anticancer ingredient and cytotoxicity of extracts from pepper were analyzed. The distilled water extracts from seed and germinated seed showed very high cytotoxicity against 6 cancer cell lines including A549 (lung carcinoma cells), AGS (stomach adenocarcinoma cells), HeLa (cervix adenocarcinoma cells), HepG2 (hepatoblastoma cells), HT-29 (colon adenocarcinoma cells), and MCF-7 (breast adenocarcinoma cells). But 80% ethanol and methanol extracts showed cytotoxicity against 293 and AGS. The $RC_{50}$, that was, the concentration of sample required for 50% reduction of cell viability, of seed and germinated seed extracts against AGS were $33.4{\sim}389.1{\mu}g/m{\ell}$ and $63.9{\sim}1,316.7{\mu}g/m{\ell}$, respectively, so anticancer activity was higher in seed than in germinated seed. In capsaicin contents, seed with high cytotoxicity and pericarp with a little cytotoxicity contained $47.4{\sim}1,260.0{\mu}g/g$ and $58.3{\sim}1,498.0{\mu}g/g$, respectively. As these results, the correlation was not between cytotoxicity and capsaicin content.

Background: To avoid performing axillary lymph node dissection (ALND) for non-sentinel lymph node (SLN)-negative patients with-SLN positive axilla, nomograms for predicting the status have been developed in many centers. We created a new nomogram predicting non-SLN metastasis in SLN-positive patients with invasive breast cancer and evaluated 14 existing breast cancer models in our patient group. Materials and Methods: Two hundred and thirty seven invasive breast cancer patients with SLN metastases who underwent ALND were included in the study. Based on independent predictive factors for non-SLN metastasis identified by logistic regression analysis, we developed a new nomogram. Receiver operating characteristics (ROC) curves for the models were created and the areas under the curves (AUC) were computed. Results: In a multivariate analysis, tumor size, presence of lymphovascular invasion, extranodal extension of SLN, large size of metastatic SLN, the number of negative SLNs, and multifocality were found to be independent predictive factors for non-SLN metastasis. The AUC was found to be 0.87, and calibration was good for the present Ondokuz Mayis nomogram. Among the 14 validated models, the MSKCC, Stanford, Turkish, MD Anderson, MOU (Masaryk), Ljubljana, and DEU models yielded excellent AUC values of > 0.80. Conclusions: We present a new model to predict the likelihood of non-SLN metastasis. Each clinic should determine and use the most suitable nomogram or should create their own nomograms for the prediction of non- SLN metastasis.

The present study was conducted to investigate the prognostic significance of co-expression patterna of HER-2, IL-6, TNF-a and TGF-${\beta}1$ in breast cancer, by correlating the number of markers with positive expression with clinicopathological characteristics indicative of tumor progression and overall survival. One hundred thirty consecutive patients with primary breast cancer were prospectively included and evaluated. Serum concentrations of the above markers were measured by ELISA. Median split was used to subdivide patients with marker positive or negative expression. The presence of ${\geq}3$ positive markers was independently associated with extended lymph node (>3) involvement (aOR, 11.94, p=0.001) and lymphovascular invasion (aOR, 12.04, p=0.018), increasing the prognostic significance of each marker considered separately. Additional prognostic information regarding survival was also provided; as the number of positive markers increased, a gradually reduction of survival time was observed. In addition, patients with 4 positive markers had significantly shorter survival (25 vs 39 months, p=0.006) and a more than 4 fold increased risk of death (aHR, 4.35, p=0.003) compared to patients with 3 positive markers. Our findings suggest that the coexpression pattern of these four markers could be used clinically as a useful marker for tumor extension and outcome of breast cancer.
