Background: The use of statistical methods has become an imperative tool in breast cancer survival data analysis. The purpose of this study was to develop the best statistical probability model using the Bayesian method to predict future survival times for the black non-Hispanic female breast cancer patients diagnosed during 1973-2009 in the U.S. Materials and Methods: We used a stratified random sample of black non-Hispanic female breast cancer patient data from the Surveillance Epidemiology and End Results (SEER) database. Survival analysis was performed using Kaplan-Meier and Cox proportional regression methods. Four advanced types of statistical models, Exponentiated Exponential (EE), Beta Generalized Exponential (BGE), Exponentiated Weibull (EW), and Beta Inverse Weibull (BIW) were utilized for data analysis. The statistical model building criteria, Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), and Deviance Information Criteria (DIC) were used to measure the goodness of fit tests. Furthermore, we used the Bayesian approach to obtain the predictive survival inferences from the best-fit data based on the exponentiated Weibull model. Results: We identified the highest number of black non-Hispanic female breast cancer patients in Michigan and the lowest in Hawaii. The mean (SD), of age at diagnosis (years) was 58.3 (14.43). The mean (SD), of survival time (months) for black non-Hispanic females was 66.8 (30.20). Non-Hispanic blacks had a significantly increased risk of death compared to Black Hispanics (Hazard ratio: 1.96, 95%CI: 1.51-2.54). Compared to other statistical probability models, we found that the exponentiated Weibull model better fits for the survival times. By making use of the Bayesian method predictive inferences for future survival times were obtained. Conclusions: These findings will be of great significance in determining appropriate treatment plans and health-care cost allocation. Furthermore, the same approach should contribute to build future predictive models for any health related diseases.

Patients with breast cancer can be positioned with their head turned to the contra lateral side or with their head straight during the radiation therapy treatment set-up. In our hospital, patients with locally advanced breast cancer who were receiving radiation therapy have experienced swallowing difficulty after 2 weeks of irradiation. In this pilot study, the impact of head position on reducing dysphagia occurrence was dosimetrically evaluated. Patients were divided into two groups viz., HT (head turned to the contra lateral side of the breast) and HS (head straight) with 10 members in each. Treatment planning was performed, and the dosimetric parameters such as Dmin, Dmax, Dmean, V₅, V₁₀, V₂₀, V₃₀, V₄₀, and V₅₀ of both groups were extracted from the dose volume histogram (DVH) of esophagus. The target coverage in the supraclavicular fossa (SCF) region was analyzed using D₉₅ and D₉₈; moreover, the dose heterogeneity was assessed with D₂ from the DVHs. The average values of the dose volume parameters were 27.6%, 58.6%, 35.4%, 19%, 13.8%, 14.1%, 11.8%, 8.4%, and 8.1% higher in the HT group compared with those in the HS group. Furthermore, for the SCF, the mean values of D₉₈, D₉₅, and D₂ were 42.4, 47.5, and 54 Gy, respectively, in the HS group and 38.9, 45.35, and 55.5 Gy, respectively, in the HT group. This pilot study attempts to give a solution for the poor quality of life of patients after breast radiotherapy due to dysphagia. The findings confirm that the head position could play a significant role in alleviating esophageal toxicity without compromising tumor control.

Purpose: The purpose of this study was to evaluate dynamic contrast-enhanced breast magnetic resonance imaging (DCE-MRI), and diffusion-weighted imaging (DWI) variables, for axillary lymph node (ALN) metastasis in the early stage of breast cancer. Materials and Methods: January 2011-April 2015, 787 patients with early stage of breast cancer were retrospectively reviewed. Only cases of invasive ductal carcinoma, were included in the patient population. Among them, 240 patients who underwent 3.0-T DCE-MRI, including DWI with b value 0 and $800s/mm^2$ were enrolled. MRI variables (adjacent vessel sign, whole-breast vascularity, initial enhancement pattern, quantitative kinetic parameters, signal enhancement ratio (SER), tumor apparent diffusion coefficient (ADC), peritumoral ADC, and peritumor-tumor ADC ratio) clinico-pathologic variables (age, T stage, multifocality, extensive intraductal carcinoma component (EIC), estrogen receptor, progesterone receptor, HER-2 status, Ki-67, molecular subtype, histologic grade, and nuclear grade) were compared between patients with axillary lymph node metastasis and those with no lymph node metastasis. Multivariate regression analysis was performed, to determine independent variables associated with ALN metastasis, and the area under the receiver operating characteristic curve (AUC), for predicting ALN metastasis was analyzed, for those variables. Results: On breast MRI, moderate or prominent ipsilateral whole-breast vascularity (moderate, odds ratio [OR] 3.45, 95% confidence interval [CI] 1.28-9.51 vs. prominent, OR = 15.59, 95% CI 2.52-96.46), SER (OR = 1.68, 95% CI 1.09-2.59), and peritumor-tumor ADC ratio (OR = 6.77, 95% CI 2.41-18.99), were independently associated with ALN metastasis. Among clinico-pathologic variables, HER-2 positivity was independently associated, with ALN metastasis (OR = 23.71, 95% CI 10.50-53.54). The AUC for combining selected MRI variables and clinico-pathologic variables, was higher than that of clinico-pathologic variables (P < 0.05). Conclusion: SER, moderate or prominent increased whole breast vascularity, and peritumor-tumor ADC ratio on breast MRI, are valuable in predicting ALN metastasis, in patients with early stage of breast cancer.

Purpose: The purpose of this study was to describe the experiences of the process of the change in cognitive function for women treated with chemotherapy for breast cancer. Methods: There were ten participants in total in this study. Data were gathered utilizing in-depth interviews over 3 times from September 2010 to January 2011. Data were analyzed by employing Strauss and Corbin's (1998) grounded theory methodology. Results: Findings indicate that causal conditions of these results were 'side effects of chemotherapy' and 'menopausal state', including contextual conditions as, 'mental fatigue' and 'anxiety about recurrence'. The core category was identified as 'confronting with unexpected chaos'. Intervening conditions were 'support from other people', 'lack of information on cognitive impairment'. Interaction strategies were 'changing the habit of life', 'making efforts for living life' and 'seeking for medical information'. Consequences of the process were 'physical restriction', 'difficulty in social life', 'disturbed working ability' and 'psychological distress'. Conclusion: The results of this study show that nurses should recognize there is a notable difference between individual patient's contextual conditions and interactive strategies. Furthermore educational information and individualized intervention should be provided to improve cognitive function for women with breast cancer.

본 연구는 거대유방암 환자대상으로 환자의 움직임과 모양의 변화에 따른 선량변화를 콘빔단층촬영영상(CBCT)과 변형영상정합기법(DIR)을 적용하여 적응형방사선치료계획을 재구성하여 기존에 사용된 쐐기접선조사기법(TWF)과 종속조사면 병합치료방법(FIF) 그리고 세기조절방사선치료계획(IMRT)을 이용하여 선량비교평가를 시행하고자 하였다. CT와 CBCT를 MIM6 사용하여 변형영상정합기법영상(DIRCT)을 만들어 각각의 치료계획을 시행하였다. 계획표적체적(PTV)은 왼쪽 유방이고 균질성지표(HI), 적합성지표(CI), 조사범위지표(CVI)의 값을 확인하였다. 관심장기(OAR)는 반대쪽 유방, 폐 그리고 심장이며 평균선량, 최대선량과 장기 특성에 따른 기타 지표들을 비교 분석하였다. PTV인 유방의 HI 값은 DIRCT를 이용한 모든 치료계획방법에서 증가하였으며, CVI, CI의 결과에서는 DIRCT를 이용한 치료계획방법에서 모두 감소하였다. 폐에서의 평균선량과 최대선량은 DIRCT 이용한 IMRT 치료계획방법이 다른 치료계획보다 증가함을 보였으며, 심장의 평균선량과 최대선량은 DIRCT를 이용한 TWF와 FIF는 감소했으며, 오히려 IMRT의 결과는 증가하였다. 유방암 방사선치료 시 환자의 움직임과 셋업 오차로 인해 유방모양의 변경을 감암했을 때 TWF와 IMRT보다 FIF 방법을 이용했을 때 반대편 유방과 심장, 폐의 피해선량을 효과적으로 감소시킬 수 있을 것으로 사료된다.

유방의 관상피내암(DCIS; ductal carcinoma in situ)은 유방의 상피세포가 악성화되었지만, 아직 정상적인 유관에 한정되어 있는 경우를 지칭하며, 최근 빠르게 증가하고 있다. 본 증례에서 추적관찰 2년 동안은 유방 촬영술 및 초음파 검사상 병변은 BI-RADS Category 3으로 분류되는 작은 mass가 관찰되었지만 낭성 mass 소견을 보여, 전형적인 악성 종양의 소견과는 거리가 있었으나 추적관찰 2년째에 유방초음파상 우측 유방 6시 방향에 불분명한 경계(Lobulated margin)를 보이는 저에코(hypoechoic) 종괴가 약 2.1 × 1.3 cm 크기로 보였으며 조직 검사상 관상피내암으로 진단되었다. 관상피내암은 특징적인 임상소견이 없고 초기에 양성의 임상, 영상 소견을 보일 수 있으므로 정기적인 추적관찰을 시행하는 것이 조기 진단에 중요할 것으로 사료되며, 유방촬영술과 초음파 검사로 관상피내암을 발견하는 것은 유방암 환자 전체의 예후를 좋게 하는 데에 중요하다고 할 수 있겠다. 4년 전 처음 검사 시 증상이 없으며 유방촬영상 정상이고 유방초음파상 악성 징후 없는 낭성병변이 추적관찰 중에 관상피내암의 소견인 비대칭 음영과 미세석회화, 분엽상의 mass가 관찰된 관상피내암의 증례를 보고한다.

Purpose: Mondor's disease is a rare benign condition which involves thrombophlebitis of the superficial veins of the breast and anterior chest wall after breast surgery, breast tissue biopsy, inflammatory reaction, breast cancer, trauma. The affected veins include the lateral thoracic, axillary veins, thoracoepigastric veins and superior epigastric veins. Methods: A 49-year-old woman presented to the outpatient department with complaints of the sudden appearance of a subcutaneous cord just under the skin at left lower lateral abdominal wall 1 month later of bilateral mastectomy due to both severe breast paraffinoma. The cord was initially red and tender and subsequently became a painless, tough, fibrous band that was accompanied by tension and skin retraction. Results: On ultrasonographic findings, palpable threadlike structures at both lateral superficial abdominal wall after bilateral mastectomy were noted. Superficial short elongated hypoechoic tubular structures were noted just under the skin at palpable lower lateral abdominal wall. It was compatible to Mondor's disease of thoracoepigastric vein. Conclusion: The increase in breast surgery will give rise to the increase in the frequency of Mondor's disease clinically. Mondor's disease can be diagnosed with clinical symptoms and image findings and the disease has proved to be benign and self-limited.
