    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

  7. Radiotherapy Boost Following Conservative Surgery for Locally Advanced Breast Cancer

    2009-01-01

    Nearly half of breast cancer patients in developing countries present with a locally advanced cancer. Treatment is centered on a multimodal approach based on chemotherapy, surgery and radiotherapy. The growing use of neoadjuvant chemotherapy has led to a more conservative surgical approach; nonetheless, it is not yet considered as a standard. There are no clear recommendations on the use of a radiotherapy boost in such situation. A Medline search was developed. Most articles are retrospective series. Survival free of locoregional relapse in patients treated with neoadjuvant chemotherapy, breast conserving surgery and radiotherapy is good. All articles described a boost administered to nearly all patients without regard to their prognostic factors, given that a locally advanced tumor is already considered as a poor prognostic factor. Even tough the poor level of evidence, a recommendation can be made: radiotherapy boost should be administered to all patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and breast conserving surgery.

    Neoadjuvant radiotherapy for breast cancer has rarely been reported. In the present study, we investigated the objective response and histopathological effects of neoadjuvant radiotherapy in patients with primary advanced or locally recurrent breast cancer. Between 1992 and 1997, a total of 11 patients with primary or recurrent breast cancer (5 primary advanced and 6 locally recurrent breast cancers) were treated with neoadjuvant radiotherapy before surgery. Six patients received radiotherapy alone and 5 received radiotherapy in combination with chemotherapy, and the objective response was assessed according to the criteria of the Japanese Society of Cancer Therapy. After neoadjuvant radiotherapy or radiochemotherapy, all patients underwent surgery or biopsy, and histopathological effects were assessed according to the criteria of the Japanese Research Society for Gastric Cancer Study. The overall objective response was 27% (3PR/11; 2PR in 5 primary cancers and 1PR in 6 recurrent cancers), and histopathological effects included 5 grade-3 or -2 responses (45%; 2 grade-3 and 1 grade-2 in primary cancers and 2 grade-2 in recurrent cancers). There were no correlations between total radiation dose and objective response or histopathological effects. The objective response rates were 40% (2/5) in the radiochemotherapy group and 17% (1/6) in the radiotherapy alone group, histopathological effects higher than grade-2 were seen in 60% (3/5) in the radiochemotherapy group and 33% (2/6) in the radiotherapy alone group, and a grade-3 response was seen only in the radiochemotherapy group. Neoadjuvant radiotherapy for breast cancer resulted in a high response rate and was more effective against primary cancer than recurrent cancer. Furthermore, chemotherapy may be beneficial in improving the efficacy of radiotherapy. (author)

    Full Text Available Objective: Patients with locally advanced breast cancer may undergo breast conserving surgery after neoadjuvant chemotherapy. The aim of the study is to evaluate the results of locally advanced breast cancer patients who underwent breast conserving surgery, axillary dissection and sentinel lymph node biopsy in a single center. Material and Methods: 12 patients with locally advanced breast cancer stage IIIA/IIIB were included in the study between 2002-2009. The patients were given anthracycline-based regimen before surgery. Patients underwent breast conserving surgery, axillary dissection, and sentinel lymph node biopsy followed by radiotherapy. Results: There were five patients in stage IIIA, six in stage IIIB, and one in stage IIIC. Patients had received 3-6 regimen of FAC/FEC. Eight had partial and four had complete response. Five positive axilla were detected. The median value of the lymph nodes was 12 (n:8-19. Five patients underwent sentinel lymph node biopsy. The biopsy has failed in one patient and the median value of dissected sentinel node was 3.5 (n:3-4. Locoregional recurrence was not observed in any patients. The mean follow-up of the patients was 29.8 months and median time was 16 (n:2-80 months.Of the 12 patients 10 are alive and 2 were deceased. Conclusion: In selected locally advanced patients, breast conserving surgery and sentinel lymph node biopsy may be applied by a multidisciplinary approach, and excellent success may be achieved in those patients as in early breast cancer patients.

    Phyllodes tumor of the breast is a rare biphasic neoplasm, accounting for less than 1% of all breast tumors. Coexistence of phyllodes tumor and breast cancer in distinct breasts is extremely rare. A 47-year-old Japanese woman presented with bilateral breast lumps. A HER2-positive, unresectable invasive carcinoma in the right breast and fibroadenoma in the left were diagnosed via core needle biopsy. During chemotherapy with anti-HER2 therapy, the breast cancer shrank quickly, while the left breast lump suddenly enlarged. Under a diagnosis of malignant neoplasm of the breast, left mastectomy was performed. Malignant phyllodes tumor was diagnosed by postoperative histological examination and recurred in multiple areas as early as 2 months after surgery. Only 10 cases of coexisting phyllodes tumor and breast cancer in distinct breasts have been reported in the English literature. Phyllodes tumor associated with breast cancer in distinct breasts tends to be malignant. This is the first case of phyllodes tumor rapidly enlarging during anti-HER2 chemotherapy for locally advanced HER2-positive breast cancer. Even during effective treatment of advanced or recurrent breast cancer, attention should also be paid to the contralateral breast for the possible association of a second malignancy such as phyllodes tumor.

    Thirteen cases of inoperable advanced breast cancer were treated with radiotherapy between 2002 to 2012 at Nara Prefectural Hospital. All cases were treated by radiotherapy and chemo-endocrine therapy. Patients received 60-81 Gy (median 60 Gy) to the primary breast tumor. Response of the breast tumors were complete response in 3 cases (23%), partial response in 8 cases (62%) and stable disease in 2 cases (15%) (response rate: 85%). All breast tumors had been controlled and skin troubles were reduced. Radiotherapy for breast cancer is useful for primary tumor control and improved quality of life (QOL). Radiotherapy should be considered to be useful modality in the treatment of advanced breast cancer. (author)

    The optimal local-regional treatment for patients with Stage III breast cancer has not been determined. To evaluate the effectiveness of radiation therapy as local treatment for such patients, the results of 192 patients (five with bilateral disease) treated with radiation therapy without mastectomy between July 1, 1968 and December 31, 1981 were reviewed. Excisional biopsy (gross tumor removal) was performed in only 54 of the 197 breasts. Patients typically received 4500 to 5000 cGy in 5 weeks to the breast and draining lymph nodes; a local boost to areas of gross disease was delivered to 157 patients. Multi-agent chemotherapy was given to 53 patients. The median follow-up was 65 months. The actuarial probability of survival for the entire group was 41% at 5 years and 23% at 10 years. The probability of relapse-free survival (RFS) was 30% at 5 years and 19% at 10 years. The addition of multi-agent chemotherapy was associated with a significantly improved 5-year RFS (40% versus 26%, P = 0.02). The 5-year survival rate was 51% for patients who received adjuvant multi-agent chemotherapy and 38% for patients who did not (P = 0.16). The actuarial rate of local-regional tumor control (not censored for distant failure) for all patients was 73% at 5 years and 68% at ten years, and the crude incidence of local-regional control was 78%. Local-regional tumor control was principally influenced by radiation dose. Patients who received 6000 cGy or greater to the primary site had a better 5-year rate of control in the breast than did patients who received less than 6000 cGy (83% versus 70%, P = 0.06). Significant complications were seen in 15 patients (8%); these included moderate or severe arm edema in six patients and brachial plexopathy in four patients. Cosmetic results at last evaluation were excellent or good in 56% of evaluable patients, fair in 25%, and poor in 19%

    OBJECTIVE: We aimed to identify mechanisms driving local recurrence in a model of breast-conserving surgery (BCS) for breast cancer. BACKGROUND: Breast cancer recurrence after BCS remains a clinically significant, but poorly understood problem. We have previously reported that recurrent colorectal tumours demonstrate altered growth dynamics, increased metastatic burden and resistance to apoptosis, mediated by upregulation of phosphoinositide-3-kinase\\/Akt (PI3K\\/Akt). We investigated whether similar characteristics were evident in a model of locally recurrent breast cancer. METHODS: Tumours were generated by orthotopic inoculation of 4T1 cells in two groups of female Balb\\/c mice and cytoreductive surgery performed when mean tumour size was above 150 mm(3). Local recurrence was observed and gene expression was examined using Affymetrix GeneChips in primary and recurrent tumours. Differential expression was confirmed with quantitative real-time polymerase chain reaction (qRT-PCR). Phosphorylation of Akt was assessed using Western immunoblotting. An ex vivo heat shock protein (HSP)-loaded dendritic cell vaccine was administered in the perioperative period. RESULTS: We observed a significant difference in the recurrent 4T1 tumour volume and growth rate (p < 0.05). Gene expression studies suggested roles for the PI3K\\/Akt system and local immunosuppression driving the altered growth kinetics. We demonstrated that perioperative vaccination with an ex vivo HSP-loaded dendritic cell vaccine abrogated recurrent tumour growth in vivo (p = 0.003 at day 15). CONCLUSION: Investigating therapies which target tumour survival pathways such as PI3K\\/Akt and boost immune surveillance in the perioperative period may be useful adjuncts to contemporary breast cancer treatment.

    The rate of local recurrence after mastectomy is reportedly similar to that of one-stage reconstruction. Most recurrences are in the skin or chest wall, while recurrence in the reconstructed breast is rare and the causes are uncertain. We report a case of a 42-year-old female who underwent partial mastectomy for left breast cancer with cT4aN0M1(PUL), cStage IV after endocrine therapy 3 years ago. Histopathological diagnosis was solid-tubular carcinoma. She had been treated with only endocrine therapy but diagnosed with local recurrence in the left breast. She underwent total mastectomy and rectus abdominis musculocutaneous flap reconstruction. Partial flap necrosis occurred following conservative therapy. She was accordingly treated with anastrozole and GnRH agonist. A mass approximately 1.5 cm in size was palpated inside of the reconstructed breast. As such, she was diagnosed with recurrence in the reconstructed breast through ultrasound biopsy. She underwent partial resection of the left precordial tumor, and histopathological examination revealed scirrhous cancer. She is currently well without any recurrence.

    A small proportion of breast cancer, in particular those cases arising at a young age, is due to the inheritance of dominant susceptibility genes conferring a high risk of the disease. A genomic linkage search was performed with 15 high-risk breast cancer families that were unlinked to the BRCA1 locus on chromosome 17q21. This analysis localized a second breast cancer susceptibility locus, BRCA2, to a 6-centimorgan interval on chromosome 13q12-13. Preliminary, evidence suggests that BRCA2 confers a high risk of breast cancer but, unlike BRCA1, does not confer a substantially elevated risk of ovarian cancer.

    Local treatment options for early stage breast cancer include mastectomy or breast-conserving therapy (BCT), the latter consisting of local excision followed by radiotherapy. For all age groups, the risk of local recurrence after BCT is higher than after mastectomy, with similar survival rates.

    We conducted a retrospective study to assess the follow-up of patients with localized breast cancer and the first indicators of advanced breast cancer recurrence. All patients with advanced breast cancer recurrence treated between January 2010 and June 2016 in our institution were registered. Among these patients, 303 patients initially treated for early breast cancer with curative intent were identified. After initial curative treatment, follow-up involved the oncologist, the general practitioner and the gynecologist in 68.0%, 48.9% and 19.1% of cases, respectively. The median DFI was 4 years for luminal A, 3.8 years for luminal B, 3.7 years for HER2-positive and 1.5 years for TNBC (p = 0.07). Breast cancer tumor marker was prescribed for 164 patients (54.1%). No difference in terms of follow-up was observed according to the molecular subtype. Symptoms were the primary indicator of relapse for 143 patients (47.2%). Breast cancer recurrence was discovered by CA 15.3 elevation in 57 patients (18.8%) and by CAE elevation in 3 patients (1%). The rate of relapse diagnosed by elevation of CA 15.3 or CAE was not statistically associated with the molecular subtype (p = 0.65). Luminal A cases showed a significantly higher rate of bone metastases (p = 0.0003). TNBC cases showed a significantly higher rate of local recurrence (p = 0.002) and a borderline statistical significant higher rate of lung/pleural metastases (p = 0.07). Follow-up recommendations could be adapted in clinical practice according to the molecular subtype. General practitioners should be more involved by the specialists in breast cancer follow-up.

    With accumulating evidence supporting partial-breast irradiation, we conducted a Phase I/II study to evaluate the role of a second conservative surgery and brachytherapy for patients presenting with a local recurrence/new primary in a breast who has previously undergone a lumpectomy and external radiation therapy for breast cancer. Fifteen patients with a localized lesion in the breast have undergone a second lumpectomy and received low-dose-rate brachytherapy on protocol. The first 6 patients received a dose of 30Gy. With no unacceptable acute toxicity observed, the brachytherapy dose was increased to 45Gy. Three patients received adjuvant chemotherapy and 8 patients are on antiestrogen therapy. The median time interval between the primary breast cancer diagnosis and the second cancer event in the ipsilateral breast is 94 months (range, 28-211). With a median followup of 36 months after brachytherapy, the 3-year Kaplan-Meier overall survival, local disease-free survival and mastectomy-free survival are 100% and 89%, respectively. There was no Grade 3/4 fibrosis or necrosis observed. All patients had baseline asymmetry due to the breast volume deficit from the second lumpectomy. With breast asymmetry as a given, the cosmetic result observed in all patients has been good to excellent. Early results suggest low-complication rates, high rate of local control and freedom from mastectomy. Additional studies are needed to establish whether a second lumpectomy and breast brachytherapy are an acceptable alternative to mastectomy for patients presenting with a localized cancer in a previously irradiated breast.

    Purpose: Local control rates for breast cancer in genetically predisposed women are poorly defined. Because such a small percentage of breast cancer patients have proven germline mutations, surrogates, such as a family history for breast cancer, have been used to examine this issue. The purpose of this study was to evaluate local-regional control following breast conservation therapy (BCT) in patients with bilateral breast cancer and a breast cancer family history. Methods and Materials: We retrospectively reviewed records of all 58 patients with bilateral breast cancer and a breast cancer family history treated in our institution between 1959 and 1998. The primary surgical treatment was a breast-conserving procedure in 55 of the 116 breast cancer cases and a mastectomy in 61. The median follow-up was 68 months for the BCT patients and 57 months for the mastectomy-treated patients. Results: Eight local-regional recurrences occurred in the 55 cases treated with BCT, resulting in 5- and 10-year actuarial local-regional control rates of 86% and 76%, respectively. In the nine cases that did not receive radiation as a component of their BCT, four developed local-regional recurrences (5- and 10-year local-regional control rates of BCT without radiation: 49% and 49%). The 5- and 10-year actuarial local-regional control rates for the 46 cases treated with BCT and radiation were 94% and 83%, respectively. In these cases, there were two late local recurrences, developing at 8 years and 9 years, respectively. A log rank comparison of radiation versus no radiation actuarial data was significant at p = 0.009. In the cases treated with BCT, a multivariate analysis of radiation use, patient age, degree of family history, margin status, and stage revealed that only the use of radiation was associated with improved local control (Cox regression analysis p = 0.021). The 10-year actuarial rates of local-regional control following mastectomy with and without radiation were 91% and 89

    Yes Associated Protein (YAP) has been implicated in the control of organ size by regulating cell proliferation and survival. YAP is a transcriptional coactivator that controls cellular responses through interaction with TEAD transcription factors in the nucleus, while its transcriptional functions are inhibited by phosphorylation-dependent translocation to the cytosol. YAP overexpression has been associated with different types of cancer, such as lung, skin, prostate, ovary and liver cancer. Recently, YAP was linked to E-cadherin-dependent regulation of contact inhibition in breast cancer cells. In this study we examined YAP protein expression and cellular localization in 237 cases of human invasive breast cancer by immunohistochemistry and related its expression to clinicopathological features and E-cadherin expression. We observed that invasive lobular carcinoma is characterized by higher expression levels of both nuclear and cytosolic YAP (p invasive breast cancer. We observed that high nuclear and cytosolic YAP expression are associated with the E-cadherin deficient breast cancer subtype ILC (p cancers and conditional mouse models of human lobular breast cancer. Since our data indicate that nuclear YAP localization is more common in breast cancers lacking functional adherens junctions, it suggests that YAP-mediated transcription may be involved in the development and progression of invasive lobular breast cancer.

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    The purpose of this study was to evaluate the outcome of breast conserving surgery comparing oncoplastic surgery (OS) and standard lumpectomy (SL) after preoperative bracketing wire localization of large neoplastic lesions. We retrospectively reviewed the medical records and the mammograms of patients operated on at the Institut Curie between May 2005 and September 2011 after bracketing wire localization under mammographic and/or sonographic guidance. 113 patients underwent surgery for a pre-operative diagnosis of DCIS (n = 80), micro-invasive carcinoma (n = 9) or invasive carcinoma (n = 24), by OS (n = 73) or SL (n = 40). In the OS group, radiological size (52 mm vs 39 mm, p breast cancer and one death unrelated to cancer occurred. Following bracketing wire localization, OS allowed the conserving management of significantly larger lesions with wider resection volumes, without significant increase in margin involvement or re-intervention rate, and equivalent rate of microcalcifications clearance compared to SL.

    Oncological outcomes of the oncoplastic breast surgery in patients with locally advanced breast cancer (LABC) are not well defined. This study examined the effects of oncoplastic techniques for LABC in terms of localized control and survival. We also evaluated the esthetic results of patients who had undergone oncoplastic breast conservation surgery (OBCS) and their satisfaction with the outcome. The files and Medula (Probel Co.) database records of the patients were studied retrospectively. The esthetic evaluation was conducted by a panel. A validated satisfaction study was also performed. In total, 42 LABC cases (median age 48 years; range 33-69 years) were included. The median observation period was 61 months (range 26-151 months). Neoadjuvant chemotherapy (NACT) was administered in 32 (76%) cases, and a pathologic complete response was observed in 7 (16.7%) cases. The median T size during the post-NACT pathological study was 27 mm (range 0-44 mm). Oncoplastic reduction surgery was performed in 13 cases, a glandular flap in 7, Grisotti flap in 5, and latissimus dorsi flap in 3 cases. The median specimen weight was 198 g (range 103-812 g), and the mean surgical margin length was 8.7 mm (range 5-17 mm). The margin was positive in 7.1% of cases, and the local repetition rate was 14.6%. The total survival rate was 86.6%, and disease-free survival was 59.6%. The rate of excellent and good ratings by the esthetic assessment panel was 79.4%. The satisfaction rate was 88.2%. The early and delayed complication rate was 16.7%. Oncoplastic techniques are suitable and safe for patients undergoing OBCS. These techniques do not pose a risk to oncological local control. No survival or follow-up problems were detected during the 5-year follow-up period, the esthetic results were acceptable, and the satisfaction rate was high.

Both unperturbed monolayer cultures and wound-healing models were examined using double-staining for thymosin ß10 and polymerized (F-) actin. Our findings...... show that thymosin ß10 is expressed in all three-cancer cell lines (SK-BR-3, MCF-7 and MDA-MB-231) studied. No or little staining was detected in confluent cells, whereas strong staining occurred in semiconfluent cells and in cells populating monolayer wounds. Importantly, the distribution of staining...... for thymosin ß10 was inverse of staining for F-actin. These data support a physiological role for thymosin ß10 in sequestration of G-actin as well as in cancer cell motility....

    Objective: To evaluate survival after treatment with mastectomy and teletherapy for locally advance breast cancer at the National Cancer Institute of Colombia. Methods: A case serie analysis was conducted. Frequencies and measures of central tendency were applied. Locoregional relapse free survival, disease free survival and overall survival were determined with Kaplan-Meyer and Cox regression analyses. Results: 174 patiens were included. Most of the patients corresponded to ductal tumors with positive axillary nodes and hormone receptors. The treatment was neoadjuvant chemotherapy, mastectomy, axillary nodes resection, radiotherapy, and adjuvant hormone therapy. The 5-years locoregional relapse free survival was 88.8%, disease free survival was 63.3%, and overall survival 84.4%. Conclusions: The results are similar to previous reports. Breast reconstruction was associated with a greater chance of locoregional relapse. The node rate is a relevant predictor for overall survival, disease free survival, and locoregional relapse free survival, and tumor grade for the former two.

    Oncoplastic reconstructive surgery is performed in select patients with breast cancer to allow conservation treatment when the lumpectomy would be expected to have a poor cosmetic outcome. These techniques not only rearrange the breast tissue but may also shift the position of the tumor bed. The oncoplastic incision may have no relationship to the tumor bed. Although use of whole-breast radiation therapy (RT) is straightforward, difficulties in localization of the tumor bed for the local RT boost have not been investigated. A retrospective review was performed of 25 patients with 26 cancers who received RT after breast conservation surgery with oncoplastic reconstruction. Among 11 patients with a minimum of 4 surgical clips placed at tumor resection, 8 (73%) had the final tumor bed extend beyond the original breast quadrant or be completely relocated into a different region. In 3 (27%) cases, the clinical treatment volume was 2 to 3 separated regions within the breast. For breast cancer patients who have had oncoplastic surgery, the tumor bed is frequently more extensive and possibly relocated compared with original presentation. Placement of surgical clips after tumor resection and before oncoplastic reconstruction may be the most accurate method to localize the RT local boost field.

    To examine the current data supporting use of social media in breast cancer clinical care. Although opportunities to utilize social media to increase knowledge have been commonly seized, the opportunity to improve communication among clinicians is lagging. Locally advanced breast cancer (LABC) requires timely coordination of care among many specialists, and presents an excellent scenario for enhanced utilization of current IT strategies. A systematic review was conducted to assess the use of social media to enhance breast cancer care. In addition, a Web-based search using common search engines and publicly available social media was conducted to determine the prevalence of information and networking pages aimed at patients and clinicians. Over 400 articles were retrieved; 81% focused on delivery of information or online support to patients, 17% focused on delivery of information to physicians, and 1% focused on the use of social media to improve collaboration among clinicians. Web searches retrieved millions of hits, with very few hits relating to improving collaboration among clinicians. Although there is significant potential to utilize current technologies to improve care for patients and improve connectedness among clinicians, most of the currently available technologies focus solely on the delivery of information.

    The study included 128 patients with stage T2-4N0-3M0 locally advanced breast cancer. All patients were divided into two groups. Group I (study group) consisted of 68 patients, who received neutron therapy, and group II (control group) comprised 60 patients, who received electron beam therapy. Neutron therapy was well tolerated by the patients and 1-2 grade radiation skin reactions were the most common. Neutron therapy was shown to be effective in multimodality treatment of the patients with locally advanced breast cancer. The 8-year recurrence-free survival rate in the patients with locally advanced breast cancer was 94.5 ± 4.1% after neutron therapy and 81.4 ± 5.9% after electron beam therapy (p = 0.05).

    The purpose of this work is to give practical guidelines for radiotherapy of locally advanced, inflammatory and metastatic breast cancer at first presentation. A comprehensive survey of the literature using the search phrases ''locally advanced breast cancer'', ''inflammatory breast cancer'', ''breast cancer and synchronous metastases'', ''de novo stage IV and breast cancer'', and ''metastatic breast cancer'' and ''at first presentation'' restricted to ''clinical trials'', ''randomized trials'', ''meta-analysis'', ''systematic review'', and ''guideline'' was performed and supplemented by using references of the respective publications. Based on the German interdisciplinary S3 guidelines, updated in 2012, this publication addresses indications, sequence to other therapies, target volumes, dose, and fractionation of radiotherapy. International and national guidelines are in agreement that locally advanced, at least if regarded primarily unresectable and inflammatory breast cancer should receive neoadjuvant systemic therapy first, followed by surgery and radiotherapy. If surgery is not amenable after systemic therapy, radiotherapy is the treatment of choice followed by surgery, if possible. Surgery and radiotherapy should be administered independent of response to neoadjuvant systemic treatment. In patients with a de novo diagnosis of breast cancer with synchronous distant metastases, surgery and radiotherapy result in considerably better locoregional tumor control. An improvement in survival has not been consistently proven, but may exist in subgroups of patients. Radiotherapy is an important part in the treatment of locally advanced and inflammatory breast cancer that should be given to all patients regardless to the intensity and effect of

    The purpose of this study is to clarify the diagnostic accuracy of helical CT (HCT) in the determination of local tumor extent of breast cancer. One hundred forty consecutive patients with breast cancer, including 87 invasive ductal carcinomas without extensive intraductal components (EIC), 44 invasive ductal carcinomas with EIC, 2 non-invasive ductal carcinomas, and 7 invasive lobular carcinomas, were included in the study. Three-dimensional tumor diameter including whole extent was measured on HCT, and the amount of invasion to fat tissue, skin, pectoral muscle, and chest wall was estimated using a three-step scale. These results were then compared with the pathological findings. Breast cancers appeared as areas of high attenuation compared with the surrounding breast tissue in all patients. Tumor extent was correctly diagnosed by HCT to within a maximum difference of 1 cm in 88 patients (63%) and within 2 cm in 122 patients (87%). Sensitivity, specificity, and accuracy in diagnosing muscular invasion of breast cancer using HCT were 100%, 99%, and 99%, respectively. Sensitivity, specificity, and accuracy in diagnosing skin invasion of breast cancer using HCT were 84%, 93%, and 91%, respectively. HCT was able to visualize all of the tumors and detect the correct tumor extent in most patients. (author)

    Full Text Available Abstract Background Breast and prostate cancer patients often develop lesions of locally high bone turnover, when the primary tumor metastasizes to the bone causing an abnormal high bone resorption at this site. The objective of the present study was to determine whether local increased bone turnover in breast and prostate cancer patients is associated with an increase in cartilage degradation and to test in vitro whether osteoclasts or cathepsin K alone generate CTXII from human bone. Methods The study included 132 breast and prostate cancer patient, where presence of bone metastases was graded according to the Soloway score. Total bone resorption (CTXItotal and cartilage degradation (CTXII were determined. Results Breast and prostate cancer patients with bone metastases revealed significant increased levels of CTXItotal at Soloway scores 1 and higher compared to patients without bone metastases (p total significantly decreased at score 3 and 4 (p total, CTXII and CTXII/CTXItotal changed +900%, +130%, and -90%, respectively at Soloway score 4 compared to score 0. The in vitro experiments revealed that osteoclasts released CTXI fragments but not CTXII from bone specimens. The same was observed for cathepsin K. Conclusion Data suggest that an uncoupling between bone resorption and cartilage degradation occurs in breast and lung cancer patient.

  7. The subcellular localization of IGFBP5 affects its cell growth and migration functions in breast cancer

    2009-01-01

    Insulin-like growth factor binding protein 5 (IGFBP5) has been shown to be associated with breast cancer metastasis in clinical marker studies. However, a major difficulty in understanding how IGFBP5 functions in this capacity is the paradoxical observation that ectopic overexpression of IGFBP5 in breast cancer cell lines results in suppressed cellular proliferation. In cancer tissues, IGFBP5 resides mainly in the cytoplasm; however, in transfected cells, IGFBP5 is mainly located in the nucleus. We hypothesized that subcellular localization of IGFBP5 affects its functions in host cells. To test this hypothesis, we generated wild-type and mutant IGFBP5 expression constructs. The mutation occurs within the nuclear localization sequence (NLS) of the protein and is generated by site-directed mutagenesis using the wild-type IGFBP5 expression construct as a template. Next, we transfected each expression construct into MDA-MB-435 breast cancer cells to establish stable clones overexpressing either wild-type or mutant IGFBP5. Functional analysis revealed that cells overexpressing wild-type IGFBP5 had significantly lower cell growth rate and motility than the vector-transfected cells, whereas cells overexpressing mutant IGFBP5 demonstrated a significantly higher ability to proliferate and migrate. To illustrate the subcellular localization of the proteins, we generated wild-type and mutant IGFBP5-pDsRed fluorescence fusion constructs. Fluorescence microscopy imaging revealed that mutation of the NLS in IGFBP5 switched the accumulation of IGFBP5 from the nucleus to the cytoplasm of the protein. Together, these findings imply that the mutant form of IGFBP5 increases proliferation and motility of breast cancer cells and that mutation of the NLS in IGFBP5 results in localization of IGFBP5 in the cytoplasm, suggesting that subcellular localization of IGFBP5 affects its cell growth and migration functions in the breast cancer cells

    2012-01-01

    Full Text Available Breast Cancer (BC is a heterogeneous disease and arises from breast cancer initiating stem cell population in the tumor and these cells are resistant to cancer therapies. Thus identifying this cell type within the tumor clone is an important area of research to understand the mechanism of breast cancer development. Recently, our laboratory has isolated and characterized Human breast cancer mesenchymal stem cells (hBCMSCs from human breast cancer and showed the heterogeneity of these cells existing in the tumor. Therefore, our present objective is to use this model system to identify, localize and define specific breast cancer initiating cells (BCICs from the heterogeneous population of hBCMSCs cell line developed in our laboratory. Localization of specific cell types can be done by using specific cancer marker antibodies using Immunofluorescence microscopy. In this study we have used FITC labeled specific cancer antibodies i.e. p53, Rb1, Hras, Ki67, EGFR, GST, ETS1 and ATF2 to localize BCICs in this population of cells. Our results have demonstrated that few cells among many of the BC cells gave fluorescence with specific cancer antibody indicating that these cell types are BCICs that may be responsible for supporting the growth of other cell type to form tumors. The Phase Contrast Microscopy clearly showed giant cells with enlarged nucleus and scanty cytoplasm associated with many cytoplasmic granules. It also indicates that these cells are mainly responsible for supporting proliferation of surrounding cells that form a part of the BC tumor. We have further hypothesized that molecular profiling of these tumor cells will open a new avenue of molecular targeted therapies for Breast Cancer patients even at an advanced stage of disease.

    Breast conserving surgery followed by radiation therapy is the treatment of choice for early breast cancer. For patients who choice or need a mastectomy, breast reconstruction provides an acceptable alternative. Breast cancer surgery has been evolving through minimally invasive approaches. Sentinel node biopsy has already remplaced axillary lymph node dissection in the evaluation of the axilla. Local ablation of the tumor may be a valuable alternative to surgery in the future.

    We studied and analyzed therapeutic outcomes of a radical surgery under local anesthesia for breast cancer in our department. Subjects were 53 patients with breast cancer whose diagnoses were definitely made before surgery. Indications were: localized ductal carcinoma in situ (DCIS) diagnosed preoperatively; invasive carcinoma less than 3 cm in tumor diameter on ultrasound and magnetic resonance imaging scan; and clinically tumors with negative axillary lymph nodes. Operative procedures included microdochectomy or lumpectomy associated with sentinel lymph node navigation biopsy (SLNB). We could perform the operation under local anesthesia in all the 53 patients, and were not demanded to shift from local to general anesthesia. Surgical stumps were positive in 10 patients (18.9%). Of the ten patients, additional resection was performed in one, and irradiation was added to the remaining nine patients. SLNB was performed in a total of 39 patients, six (15.4%) patients of them had metastasis and two out of the six patients underwent additional axillary lymph node dissection. None of serious complications were encountered. Local recurrence and hepatic metastasis occurred in each one patient in an averaged observation period of 15.1 months. This day's radical operation under local anesthesia for breast cancer is a useful procedure as minimally invasive surgery as for the indications employed in this study. (author)

    Deregulated PI3K/mTOR signals can promote the growth of breast cancer and contribute to endocrine treatment resistance. This report aims to investigate raptor and its intracellular localization to further understand its role in ER-positive breast cancer. Raptor protein expression was evaluated by immunohistochemistry in 756 primary breast tumors from postmenopausal patients randomized to tamoxifen or no tamoxifen. In vitro, the MCF7 breast cancer cell line and tamoxifen-resistant MCF7 cells were studied to track the raptor signaling changes upon resistance, and raptor localization in ERα-positive cell lines was compared with that in ERα-negative cell lines. Raptor protein expression in the nucleus was high in ER/PgR-positive and HER2-negative tumors with low grade, features associated with the luminal A subtype. Presence of raptor in the nucleus was connected with ERα signaling, here shown by a coupled increase of ERα phosphorylation at S167 and S305 with accumulation of nuclear raptor. In addition, the expression of ERα-activated gene products correlated with nuclear raptor. Similarly, in vitro we observed raptor in the nucleus of ERα-positive, but not of ER-negative cells. Interestingly, raptor localized to the nucleus could still be seen in tamoxifen-resistant MCF7 cells. The clinical benefit from tamoxifen was inversely associated with an increase of nuclear raptor. High cytoplasmic raptor expression indicated worse prognosis on long-term follow-up. We present a connection between raptor localization to the nucleus and ERα-positive breast cancer, suggesting raptor as a player in stimulating the growth of the luminal A subtype and a possible target along with endocrine treatment.

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

  19. RKIP Inhibits Local Breast Cancer Invasion by Antagonizing the Transcriptional Activation of MMP13.

    Directory of Open Access Journals (Sweden)

    Ila Datar

    Full Text Available Raf Kinase Inhibitory Protein or RKIP was initially identified as a Raf-1 binding protein using the yeast 2-hybrid screen. RKIP inhibits the activation phosphorylation of MEK by Raf-1 by competitively inhibiting the binding of MEK to Raf-1 and thus exerting an inhibitory effect on the Raf-MEK-Erk pathway. RKIP has been identified as a metastasis suppressor gene. Expression of RKIP is low in cancer metastases. Although primary tumor growth remains unaffected, re- expression of RKIP inhibits cancer metastasis. Mechanistically, RKIP constrains metastasis by inhibiting angiogenesis, local invasion, intravasation, and colonization. The molecular mechanism of how RKIP inhibits these individual steps remains undefined. In our present study, using an unbiased PCR based screening and by analyzing DNA microarray expression datasets we observe that the expression of multiple metalloproteases (MMPs including MMP1, MMP3, MMP10 and MMP13 are negatively correlated with RKIP expression in breast cancer cell lines and clinical samples. Since expression of MMPs by cancer cells is important for cancer metastasis, we hypothesize that RKIP may mediate suppression of breast cancer metastasis by inhibiting multiple MMPs. We show that the expression signature of RKIP and MMPs is better at predicting high metastatic risk than the individual gene. Using a combination of loss- and gain-of-function approaches, we find that MMP13 is the cause of RKIP-mediated inhibition of local cancer invasion. Interestingly expression of MMP13 alone is not sufficient to reverse the inhibition of breast cancer cell metastasis to the lung due to the expression of RKIP. We find that RKIP negatively regulates MMP13 through the Erk2 signaling pathway and the repression of MMP13 by RKIP is transcription factor AP-1 independent. Together, our findings indicate that RKIP inhibits cancer cell invasion, in part, via MMP13 inhibition. These data also implicate RKIP in the regulation of MMP

    Radiation therapy plays a major role in the management of adjuvant breast cancer with nodal involvement, with an iatrogenic increase of cardio-vascular risk. Photon therapy, even with intensity modulation, has the downsides of high mean heart dose and heterogeneous target coverage, particularly in the case of internal mammary irradiation. This systematic review of the literature aims to evaluate proton therapy in locally advanced breast cancer. PubMed was searched for original full-text articles with the following search terms: «Proton Therapy» and «Breast Cancer». On-going trials were collected using the words "Breast Cancer" and "Protons". 13 articles met the criteria: 6 with passive proton therapy (Double Scattering), 5 with Pencil Beam Scanning (PBS) and 2 with a combination of both. Proton therapy offered a better target coverage than photons, even compared with intensity modulation radiation therapy (including static or rotational IMRT or tomotherapy). With proton therapy, volumes receiving 95% of the dose were around 98%, with low volumes receiving 105% of the dose. Proton therapy often decreased mean heart dose by a factor of 2 or 3, i.e. 1 Gy with proton therapy versus 3 Gy with conventional 3D, and 6 Gy for IMRT. Lungs were better spared with proton therapy than with photon therapy. Cutaneous toxicity observed with double scattering is improved with PBS. Proton therapy reduces mean heart dose in breast cancer irradiation, probably reducing late cardio-vascular toxicity. Large clinical studies will likely confirm a clinical benefit of proton therapy.

    Purpose: Tumor grading is an important part of breast cancer diagnosis and currently requires biopsy as its standard. Here, the authors investigate quantitative ultrasound parameters in locally advanced breast cancers that can potentially separate tumors from normal breast tissue and differentiate tumor grades. Methods: Ultrasound images and radiofrequency data from 42 locally advanced breast cancer patients were acquired and analyzed. Parameters related to the linear regression of the power spectrum—midband fit, slope, and 0-MHz-intercept—were determined from breast tumors and normal breast tissues. Mean scatterer spacing was estimated from the spectral autocorrelation, and the effective scatterer diameter and effective acoustic concentration were estimated from the Gaussian form factor. Parametric maps of each quantitative ultrasound parameter were constructed from the gated radiofrequency segments in tumor and normal tissue regions of interest. In addition to the mean values of the parametric maps, higher order statistical features, computed from gray-level co-occurrence matrices were also determined and used for characterization. Finally, linear and quadratic discriminant analyses were performed using combinations of quantitative ultrasound parameters to classify breast tissues. Results: Quantitative ultrasound parameters were found to be statistically different between tumor and normal tissue (p < 0.05). The combination of effective acoustic concentration and mean scatterer spacing could separate tumor from normal tissue with 82% accuracy, while the addition of effective scatterer diameter to the combination did not provide significant improvement (83% accuracy). Furthermore, the two advanced parameters, including effective scatterer diameter and mean scatterer spacing, were found to be statistically differentiating among grade I, II, and III tumors (p = 0.014 for scatterer spacing, p = 0.035 for effective scatterer diameter).

    A case was a 78-year-old woman. We detected a precordial tumor by palpation in January 2007. The patient left it untreated for a while. She then came to see us as the tumor had grown enlarged. In local findings, the precordium midline showed a non-elastic tumor of 2 cm in size. Biopsy revealed a possibility of breast cancer metastases. Mammography and the breast echography did not show any anomalies. Histopathology specific immune-staining was CK7, CEA positive, ER (+), PgR (+). The diagnosis was latent breast metastasis. Radiotherapy was performed and irradiated a total dose of 66 Gy. Our judgment was cCR in the post irradiation. After 2 years from the radiotherapy, there was no recurrence or metastases confirmed until today. In a breast cancer treatment, radiotherapy will be performed for the purpose of local control. However, we report here our experience with an unusual cCR judgment of more than 1 year for reference.

    Purpose: In young women, breast-conserving therapy (BCT), i.e., lumpectomy followed by radiotherapy, has been associated with an increased risk of local recurrence. Still, there is insufficient evidence that BCT impairs survival. The aim of our study was to compare the effect of BCT with mastectomy on overall survival (OS) in young women with early-stage breast cancer. Methods and Materials: From two Dutch regional population-based cancer registries (covering 6.2 million inhabitants) 1,453 women <40 years with pathologically T1N0-1M0 breast cancer were selected. Cox regression survival analysis was used to study the effect of local treatment (BCT vs. mastectomy) stratified for nodal stage on survival and corrected for tumor size, age, period of diagnosis, and use of adjuvant systemic therapy. Results: With a median follow-up of 9.6 years, 10-year OS was 83% after BCT and 78% after mastectomy, respectively (unadjusted hazard ratio [HR], 1.37; 95% confidence interval [CI], 1.09-1.72). In N0-patients, 10-year OS was 84% after BCT and 81% after mastectomy and local treatment was not associated with differences in OS (HR 1.19; 95% CI, 0.89-1.58; p = 0.25). Within the N1-patient group, OS was better after BCT compared with mastectomy, 79% vs. 71% at 10 years (HR 1.91; 95% CI, 1.28-2.84; p = 0.001) and in patients treated with adjuvant hormonal therapy (HR 0.34; 95% CI, 0.18-0.66; p = 0.001). Conclusions: In this large population-based cohort of early-stage young breast cancer patients, 10-year OS was not impaired after BCT compared with mastectomy. Patients with 1 to 3 positive lymph nodes had better prognosis after BCT than after mastectomy.

    Breast-conserving surgery (BCS) is considered the gold-standard treatment for early breast cancer. Ultrasound-guided percutaneous biopsy or stereotactic biopsy of a breast lesion allows preoperative histological diagnosis. Various techniques have been proposed for identifying non-palpable breast tumors, but the most popular method is the wire-guided localization (WGL) technique. The aim of this study was to propose an alternative technique for optimizing the WGL procedure, facilitating breast surgery and reducing complications. We performed a prospective study on 40 patients with a single non-palpable breast lesion. For the preoperative localization of mammary lesions, patients were divided randomly into two groups: 20 patients underwent conventional WGL technique and 20 underwent 'optimized' personalized technique. In the group treated with the optimized technique, dislocation of the wire occurred in only 2/20 cases, whereas in those with the conventional technique, dislocation occurred in 9/20 cases (p=0.03). In 5/20 cases of the conventional WGL technique, the wire was accidentally cut by the surgeon, whereas no similar complications were observed in the group that underwent the optimized technique (p=0.047). Re-excision of the surgical margins was necessary in 6/20 cases with the conventional technique, while re-excision was not required for any case using the optimized technique (p=0.02). The proposed optimized technique ensures good esthetic results, enabling the surgeon to identify the lesion and perform oncoplastic breast surgery, and allows surgical time to be reduced.

    Full Text Available The study of efficiency of intraoperative photodynamic therapy (PDT with Photosens as the step of combined modality treatment in patients with IIIВ and IIIС stages of breast cancer was performed. The long-term outcomes were evaluated in two groups of patients: group 1 – after radical extended mastectomy combined with chemotherapy, radiotherapy and chemo- and hormonal therapy (138 patients, group 2 – the same treatment combined with intraoperative PDT (36 patients. For the patients with PDT photosens was administered i.v. in single dose 0.3 mg/kg for 2 h before surgery. The irradiation of operative field was performed single time (the light dose 30 J/cm2, with separate irradiation of subclavian, axillar and adjacent regions (the light dose 50 J/cm2. The results showed that intraoperative PDT was associated with better recurrence-free survival rates in patients with breast cancer: in the PDT group the average recurrence free survival was 44.9±3.4 months, in the group without PDT — 35.3±2.1 months. The obtained results confirm that intraoperative PDT for locally advanced breast cancer can be used successfully for devitalization of cancer cells on the wound superface and for prevention of intraoperative tumor dissemination and post-operative recurrence.

    The Kennedy report into the actions of the disgraced Breast Surgeon, Paterson focussed on issues of informed consent for mastectomy, management of surgical margins and raised concerns about local recurrence rates and the increasing emphasis on cosmesis after mastectomy for breast cancer. This article assesses whether Kennedy's recommendations apply to the UK as a whole and how to address these issues. New GMC advice on consent and newer nonevidenced innovations in immediate reconstruction have altered the level of informed consent required. Patients deserve a better understanding of the issues of oncological versus cosmetic outcomes on which to base their decisions. Involvement of the whole multidisciplinary team including Oncologists is necessary in surgical planning. Failure to obtain clear microscopic margins at mastectomy leads to an increased local recurrence, yet has received little attention in the UK. Whereas, other countries have used surgical quality assurance audits to reduce local recurrence; local recurrence rates are not available and the extent of variation across the UK in margin involvement after surgery, its management and relationship to local recurrence needs auditing prospectively to reduce unnecessary morbidity. To reassure public, patients and the NHS management, an accreditation system with more rigour than NHSBSP QA and peer review is now required. Resource and efforts to support its introduction will be necessary from the Royal College of Surgeons and the Association of Breast Surgeons. New innovations require careful evaluation before their backdoor introduction to the NHS. Private Hospitals need to have the same standards imposed.

    The optimal surgical management of locally advanced breast cancer (LABC) remains undefined. The aim of the study was to obtain long-term results of oncoplastic surgery in terms of overall survival, loco-regional recurrence, and quality of life in case of LABC. Prospective cohort study enrolled 60 patients with stage III breast cancer. Forty-two (70%) patients received neo-adjuvant chemotherapy, 28 patients were considered suitable for surgery as initial treatment option. Type II oncoplastic surgery was performed for all patients: hemimastectomy and breast reconstruction with latissimus dorsi flap - for 29 (48.3%), lumpectomy - 31 (51.7%), and reconstruction with subaxillary flap for four (6.7%), with bilateral reduction mammoplasty - 14 (23.3%) and with J-plastic - 13 (21.7%) patients. Adjuvant chemotherapy and hormonal therapy followed surgery for all, except one, patients. Sequential radiotherapy was administered for all patients. The mean period of follow-up was 86 months. Postoperative morbidity rate was 5%. Local-regional recurrence was detected in six (10%) patients. After reoperation no local relapse was diagnosed. However, three of these patients had systemic dissemination of the disease. Distant metastasis was detected in 23 (38.3%) patients. Distant metastasis-free survival at 5 years was 61.7%. Fourteen patients died (23.3%). A total of 87.2% of the patients had good and excellent esthetic outcome. Oncoplastic breast-conserving surgery can be proposed for selected patients with LABC with acceptable complication, local recurrence rate, and good esthetic results. © 2013 Wiley Periodicals, Inc.

    1987-01-01

    Following local excision and definitive irradiation of 163 breast cancers in 160 women, alterations in mammographic patterns were observed for up to 7 years. Skin thickening was observed in 96% of mammograms obtained within 1 year of completing therapy and was most pronounced in women treated with iridium implant, chemotherapy, or axillary dissection. In 76% of mammograms, alterations in the parenchymal pattern, including coarsening of stroma and increased breast density, were seen at 1 year. Neither skin nor parenchymal changes progressed after 1 year. Within 3 years of treatment the parenchymal density, which usually regressed, did not change in all patients. At 3 years skin thickness and the parenchymal pattern had returned to normal in less than 50% of the breasts of these women. Scars developed in approximately one-quarter of women. They were present on the initial post-treatment mammogram and remained unchanged on serial studies. Coarse, benign calcifications also developed in the breasts of about one-quarter of women. Microcalcifications developed in 11 breasts; biopsy specimens of six were benign. Benign microcalcifications may be related to therapy

    Full Text Available Mutations in BRCA1 are associated with familial as well as sporadic aggressive subtypes of breast cancer, but less is known about whether BRCA1 expression or subcellular localization contributes to progression in population-based settings.We examined BRCA1 expression and subcellular localization in invasive breast cancer tissues from an ethnically diverse sample of 286 patients and 36 normal breast tissue controls. Two different methods were used to label breast cancer tissues for BRCA1: (1 Dual immunofluoresent staining with BRCA1 and cytokeratin 8/18 and (2 immunohistochemical staining using the previously validated MS110 mouse monoclonal antibody. Slides were visualized and quantified using the VECTRA Automated Multispectral Image Analysis System and InForm software.BRCA1 staining was more intense in normal than in invasive breast tissue for both cytoplasmic (p<0.0001 and nuclear (p<0.01 compartments. BRCA1 nuclear to cytoplasmic ratio was higher in breast cancer cells than in normal mammary epithelial cells. Reduced BRCA1 expression was associated with high tumor grade and negative hormone receptors (estrogen receptor, progesterone receptor and Her2. On the other hand, high BRCA1 expression correlated with basal-like tumors (high CK5/6 and EGFR, and high nuclear androgen receptor staining. Lower nuclear to cytoplasmic ratio of BRCA1 correlated significantly with high Ki67 labeling index (p< 0.05 and family history of breast cancer (p = 0.001.Findings of this study indicate that alterations in BRCA1 protein expression and subcellular localization in breast cancer correlate with poor prognostic markers and aggressive tumor features. Further large-scale studies are required to assess the potential relevance of BRCA1 protein expression and localization in routine classification of breast cancer.

    Between 1977 and 1980, 118 breast cancer patients with locally advanced disease, T3B-4, any N, M0 or T1-3, tumor positive axillary apex biopsy, were randomized to one of three arms: I: radiotherapy (RT) to the breast and adjacent lymph node areas; II: RT followed by 12 cycles of cyclophosphamide, methotrexate, 5 fluorouracil (CMF) and tamoxifen during the chemotherapy period; III: 2 cycles of adriamycin and vincristine (AV), alternated with 2 cycles of CMF, then RT, followed by another 4 cycles of AV, alternated with 4 CMF; tamoxifen during the entire treatment period. The median follow-up period was 5 1/2 years. The adjuvant chemo- and hormonal therapy did not improve the overall survival; the 5-year survival was 37% for all three treatment arms. There was no statistically significant difference in RFS between the three modalities, nor when arm I was compared to arm II and III together. LR was not statistically different over the three treatment arms. In 18 of the 24 patients with LR, distant metastases appeared within a few months from the local recurrence. The menopausal status did not influence the treatment results. Dose reduction in more than 4 cycles of chemotherapy was accompanied by better results. In conclusion: adjuvant chemo- and hormonal therapy did not improve RFS and overall survival. These findings do not support the routine use of adjuvant chemo- and endocrine therapy for inoperable breast cancer

    To know the prognosis of a patient with cancer allows choosing the most appropriate therapeutic. The expression of the oncogen HER2/neu has been related to an unfavourable prognosis in patients with infiltrating breast carcinoma, for this reason, the purpose of this work was to analyze its predictive and prognostic value in patients with locally advanced breast cancer, treated in the Oncological Institute "Dr Miguel Perez Carreño". Information about personal data of 58 patients was compiled, as well as the received treatment, clinical response data of the biopsy report, histological grade, nuclear grade, node status and evolution of the patient. The determination of the HER2/neu expression was made by inmunohistochemistry, using the avidina-estreptavidin-peroxidasa technique. For the interpretation of the HER2/neu, an agreed score from 0 to 3+ was assigned, using the guidelines of interpretation of the Hercep-Test (DAKO). 37.9% of the cases displayed expression of the HER2/neu in the membrane of the tumour cells. The node state and the hormonal receptors state turned out to be significant to predict the disease-free interval. Patients with strong oncoprotein expression seem to have a quimioresistant tendency to the FAC (5-fluorouracil, doxorubicin and cyclophosphamide) regime. The expression of the HER2/neu receptor is related to a reduction of the disease-free interval and global survival in patients with infiltrating ductal breast carcinoma locally advanced, confirming, in this work, to be a good prognostic factor.

    Full Text Available Purpose: The aim of this study was to evaluate whether treatment with a local potent corticosteroid during adjuvant external radiotherapy (ERT of breast cancer is associated with late skin toxicity. Material and methods: Sixty patients (32 treated with potent corticoid cream versus 28 controls treated with moisturizer who had been included in a randomized study on prophylactic local corticosteroid treatment under adjuvant ERT in 2009 and 2010 were subjected to a follow-up study in 2016.Assessments of skin texture were registered according to the Late Radiation Morbidity Scoring Scheme (RTOG. Dryness, skin colour and skin thickness were objectively measured using non-invasive instruments. The patients were assessed for differences between their treated and untreated breasts. Results: Skin atrophy was not noticed in any of the 60 patients. Objective instrumental measurements did not reveal any significant differences in skin dryness, colour, pigmentation or skin thickness over the average follow-up time of six years. Clinical assessment based on the RTOG scoring system revealed that the odds ratio of having late skin problems in patients treated with moisturizer compared to patients treated with corticosteroid was 3.2 (95% CI: 1.0–10.1.Patients reported minor cosmetic dermatological sequelae. Seven patients developed telangiectasia, which caused cosmetic inconvenience. Conclusion: In this study, prophylactic corticosteroid treatment to ameliorate radiation dermatitis during adjuvant ERT of breast cancer was not associated with an increase in late skin toxicity nor did it result in skin atrophy. This study is limited by its small sample size, and the risk for false positive findings.

    Full Text Available Background: Neoadjuvant chemotherapy can downstage the size of the tumor, thus allowing some patients with advanced disease with the option of conservative breast surgery. Our study aims to investigate the effectiveness of neoadjuvant chemotherapy in patients with locally advanced breast cancer. Methods: Fifty-six patients had locally advanced breast cancer. Ten patients (18% were stage IIB, 32 (57% were stage IIIA, 9 (16% were stage IIIB, and 5 (9% were stage IIIC. Patients received neoadjuvant chemotherapy comprised of cyclophosphamide, doxorubicin, and fluorouracil followed by surgery (15 patients with breast conservative surgery,11 with skin sparing mastectomy and latesmus dorsi reconstruction, and 30 patients who underwent modified radical mastectomy and then followed by radiotherapy, 50 Gy with conventional fractionation. Results: Clinical down staging was obtained in 49 (87.5% patients: 5 (9% had complete clinical response, 44 (78.5% had partial response, 6 (10.7% had stable disease, and 1 (1.8% had progressive disease. The primary tumor could not be palpated after chemotherapy in 7 (12.5% of 56 patients who presented with a palpable mass. Median follow-up was 47.5 months. The factors that correlated positively with locoregional recurrence on univariate analysis included hormonal receptor status and surgical margin status. On multivariate analysis, surgical margin status was the only independent significant factor for locoregional recurrence-free survival. In univariate analysis for distant relapse free survival, factors that correlated positively included disease stage and hormonal receptor status. Multivariate analysis showed that tumor stage and hormonal receptor status were independent significant factors that correlated with distant relapse-free survival. Conclusion: Neoadjuvant chemotherapy was effective in clinical down staging and should be considered for patients with advanced breast cancer. It improved operability and enhanced

    The use of breast-conserving treatment approaches for breast cancer has now become a standard option for early stage disease. Numerous randomized studies have shown medical equivalence when mastectomy is compared to lumpectomy followed by radiotherapy for the local management of this common problem. With an increased emphasis on patient involvement in the therapeutic decision making process, it is important to identify and quantify any unforeseen risks of the conservation approach. One concern that has been raised is the question of radiation- related contralateral breast cancer after breast radiotherapy. Although most studies do not show statistically significant evidence that patients treated with breast radiotherapy are at increased risk of developing contralateral breast cancer when compared to control groups treated with mastectomy alone, there are clear data showing the amount of scattered radiation absorbed by the contralateral breast during a routine course of breast radiotherapy is considerable (several Gy) and is therefore within the range where one might be concerned about radiogenic contralateral tumors. While radiation related risks of contralateral breast cancer appear to be small enough to be statistically insignificant for the majority of patients, there may exist a smaller subset which, for genetic or environmental reasons, is at special risk for scatter related second tumors. If such a group could be predicted, it would seem appropriate to offer either special counselling or special prevention procedures aimed at mitigating this second tumor risk. The use of genetic testing, detailed analysis of breast cancer family history, and the identification of patients who acquired their first breast cancer at a very early age may all be candidate screening procedures useful in identifying such at- risk groups. Since some risk mitigation strategies are convenient and easy to utilize, it makes sense to follow the classic 'ALARA' (as low as reasonably

  1. Local and Regional Breast Cancer Recurrences: Salvage Therapy Options in the New Era of Molecular Subtypes

    Full Text Available Isolated local or regional recurrence of breast cancer (BC leads to an increased risk of metastases and decreased survival. Ipsilateral breast recurrence can occur at the initial tumor bed or in another quadrant of the breast. Depending on tumor patterns and molecular subtypes, the risk and time to onset of metastatic recurrence differs. HER2-positive and triple-negative (TNG BC have a risk of locoregional relapse between six and eight times than luminal A. Thus, the management of local and locoregional relapses must take into account the prognostic factors for metastatic disease development. It is important to personalize the overall management, including or not systemic treatment according to the metastatic risk. All isolated recurrence cases should be treated with curative intent. Complete surgical resection is recommended whenever possible. Patients who did not receive postoperative irradiation during their initial management should receive full-dose radiotherapy to the chest wall and to the regional lymph nodes if appropriate. Overall, total mastectomy is the “gold standard” among patients who were previously treated by conservative surgery followed by radiation therapy. In terms of systemic therapy, the benefits of additional treatments are not conclusively proven in cases of isolated recurrence. The beneficial role of chemotherapy has been reported in at least one randomized trial, while endocrine therapy and anti-HER2 are common practice. This review will discuss salvage treatment options of local and locoregional recurrences in the new era of BC molecular subtypes.

    Full Text Available To provide reference data, we retrospectively investigated the effects of neoadjuvant chemotherapy (NAC on 119 patients with HER-2+ locally advanced breast cancer, treated from November 2010 to July 2016, with respect to influencing factors and survival. They were divided into the pathological complete response (pCR; n=15; 12.6% and non-pCR (n=104; 87.4% groups. We used Χ2 and logistic tests to the analyze effect and influencing factors. Survival rate was analyzed by the Kaplan-Meier method and Log-rank test. We lost 12 patients (including 1 pCR patient and followed 107 patients, of whom 31 (all in the non-pCR group had local recurrences or distant metastasis. The two groups significantly differed in 3-year disease-free survival (pCR group: 100%; non-pCR group: 59.0%; P=0.039; pCR was significantly affected by histological grade, PR status, Ki67 index, primary tumor size, clinical staging, and number of trastuzumab cycles. The model was tested, and the difference was statistically significant (Χ2 = 31.938, P=0.032. Patients with HER-2+ locally advanced breast cancer with pCR responses to NAC have improved prognoses. Patients without pCR have increased risk for relapse. The use of a combination of NAC, such as trastuzumab and chemotherapy, and more cycles should be considered to increase the likelihood of pCR.

    Neoadjuvant chemotherapy (NAC), the systematic chemotherapy given to patients with locally advanced and inoperable breast caner, has been proven to be of great clinical values. Many scientific reports confirmed NAC could effectively eliminate sub-clinical disseminated lesions of tumor, and improve long-term and disease-free survival rate of patients with locally advanced breast cancer (LABC); however, up to now, LABC is still a serious clinical issue given improved screening and early diagnosis. This study, with main focus on inoperable LABC, investigated the values of NAC in converting inoperable LABC into operable status and assessed the prognosis. Sixty-one patients with inoperable LABC were initially treated with neoadjuvant chemotherapy; their local conditions were improved to operable status. Radical surgery was exerted on 49 patients. Original chemotherapy was performed after surgery, followed by local radiotherapy. And endocrine therapy was optional according to the hormone receptor status. The quality of life for most patients with skin diabrosis was obviously improved because their local conditions were under control. For all recruited cases, the survival duration and life quality were significantly improved in patients who finished both NAC and surgery compared to those who did not. Further more, this study demonstrates improved prognostic consequences. PMID:28327615

    The optimal sequence of mastectomy with immediate breast reconstruction (IBR) and radiotherapy (RT) for the treatment of locally advanced breast cancer (LABC) is still under debate. Increased rates of postoperative complications are described following postmastectomy RT. Neoadjuvant RT aims to improve the aesthetic results and simplify the reconstructive pathway. A total of 22 patients diagnosed with LABC and treated with neoadjuvant RT followed by mastectomy and IBR between 04/2012 and 03/2015 were retrospectively analyzed. RT consisted of external beam RT to the breast and the regional lymphatics, if indicated. Both implant-based and autologous tissue-transfer reconstruction techniques were used. At the time of RT, 10 patients had no prior surgery and 12 patients had previously undergone breast-conserving surgery (BCS) with positive resection margins without the possibility to perform a second BCS. Additional neoadjuvant chemotherapy was administered in 18 patients prior to RT. A complete pathological response was achieved in 55.0% of patients. The 2‑year overall survival rate was 89.3%, the 2‑year disease-free-survival 79.8% and the local-recurrence-free survival was 95.2%. The cosmetic result was excellent or good in 66% of the patients treated with upfront mastectomy and 37% of the patients who had previously undergone BCS. Among patients who received implant-based IBR, 4 patients developed serious wound-healing problems with implant loss. The most satisfactory results were achieved with autologous tissue reconstruction. A sequential neoadjuvant chemo-/radiotherapy to allow IBR following mastectomy in selected cases of LABC seems feasible and can be safely attempted. Careful patient selection, close monitoring, and continuous patient support is mandatory to ensure compliance in this treatment strategy.

    To assess whether DCE-MRI pharmacokinetic (PK) parameters obtained before and during chemotherapy can predict pathological complete response (pCR) differently for different breast cancer groups. Eighty-four patients who received neoadjuvant chemotherapy for locally advanced breast cancer were retrospectively included. All patients underwent two DCE-MRI examinations, one before (EX1) and one during treatment (EX2). Tumours were classified into different breast cancer groups, namely triple negative (TNBC), HER2+ and ER+/HER2-, and compared with the whole population (WP). PK parameters Ktrans and Ve were extracted using a two-compartment Tofts model. At EX1, Ktrans predicted pCR for WP and TNBC. At EX2, maximum diameter (Dmax) predicted pCR for WP and ER+/HER2-. Both PK parameters predicted pCR in WP and TNBC and only Ktrans for the HER2+. pCR was predicted from relative difference (EX1 - EX2)/EX1 of Dmax and both PK parameters in the WP group and only for Ve in the TNBC group. No PK parameter could predict response for ER+/HER-. ROC comparison between WP and breast cancer groups showed higher but not statistically significant values for TNBC for the prediction of pCR Quantitative DCE-MRI can better predict pCR after neoadjuvant treatment for TNBC but not for the ER+/HER2- group.

  8. Influence of locoregional irradiation on local control and survival in breast cancer

    Locoregional control is a crucial step in the achievement of breast cancer cure. In ductal carcinoma in situ, breast irradiation significantly reduces the rates of local recurrence whatever the histological subtypes, as demonstrated by the NSABP-B17 trial (25.8 % of local recurrences without radiotherapy vs. 11.4 % with radiotherapy). In infiltrating breast carcinomas, complementary breast irradiation has been shown to significantly improve the local control and slightly the overall survival in five randomized trials. Following mastectomy, locoregional irradiation clearly reduces the chest wall and nodal relapse rates, especially in case of lesions more than 5 cm or with nodal involvement and/or large lymphatic or vascular emboli. Two recent randomized trials confirmed the benefit of well-adapted locoregional irradiation in all subgroups, especially in patients with one to three axillary involves nodes. In the Danish trial (including pre-menopausal high-risk women), radiotherapy reduced locoregional relapses from 32 to 9 % (p<0.001) and increased the 10-year survival rate from 45 to 54% (p<0.001). In the Canadian trial, locoregional relapse rate decreased from 25 to 13 % and the 10-year survival rate increased from 56 to 65 %. The meta-analysis published in 1995 by the EBCTCG showed only a modest benefit due to locoregional irradiation in breast cancer. However, when small or old trials were excluded due to imperfect methodology or inadequate irradiation techniques, the benefit of modern radiotherapy became much more evident in a population of 7,840 patients. Locoregional irradiation appears to be able to reduce the risk of metastatic evolution occurring after local or nodal relapse and must be integrated in a multidisciplinary strategy. Treatment toxicity (especially toxicity due to irradiation of internal mammary nodes) is of special concern, as anthracycline-based chemotherapy is prescribed more often.

    Full Text Available Abstract Background Breast cancer is the commonest cancer among women in Nigeria and globally. In Nigeria, late presentations of breast cancer cases have also been consistent for three decades. In an environment where there is no established national screening program for breast cancer, it is pertinent to assess the knowledge of breast cancer and its early detection measures. The objective of this study therefore, was to assess rural women's level of knowledge of breast cancer and its early detection measures. Methods The knowledge of various aspects of breast cancer; etiology, early warning signs, treatment modes and early detection measures; was assessed among women in two randomly selected health districts in Akinyele Local Government in Ibadan. The assessment was performed with the use of a self-structured validated questionnaire administered by trained interviewers to 420 women randomly selected from the two health districts. The various aspects of facts about breast cancer were scored and added together to determine respondents' level of knowledge Results The mean score of knowledge of breast cancer was 55.4 SD 5.4 (range of scores obtainable was 26–78, while the mean score for knowledge of early detection of breast cancer was 24.8 SD 2.3 (range of scores obtainable was 12–36. The leading source of information about breast cancer was "elders, neighbors and friends" and 63(15.4% acknowledged this source, while only 18 (4.4% respondents acknowledged health workers as source. Only 54 (13.3% claimed to have heard about breast self- examination (BSE however, and the leading source of information about BSE were health workers. Nine (2.2% of respondents claimed this source. Conclusion This study revealed that respondents lacked knowledge of vital issues about breast cancer and early detection measures. It also revealed that health workers were not forthcoming with information to the public thereby constituting a challenge to community health

  12. A novel local learning based approach with application to breast cancer diagnosis

    2012-03-01

    In this paper, we introduce a new local learning based approach and apply it for the well-studied problem of breast cancer diagnosis using BIRADS-based mammographic features. To learn from our clinical dataset the latent relationship between these features and the breast biopsy result, our method first dynamically partitions the whole sample population into multiple sub-population groups through stochastically searching the sample population clustering space. Each encountered clustering scheme in our online searching process is then used to create a certain sample population partition plan. For every resultant sub-population group identified according to a partition plan, our method then trains a dedicated local learner to capture the underlying data relationship. In our study, we adopt the linear logistic regression model as our local learning method's base learner. Such a choice is made both due to the well-understood linear nature of the problem, which is compellingly revealed by a rich body of prior studies, and the computational efficiency of linear logistic regression--the latter feature allows our local learning method to more effectively perform its search in the sample population clustering space. Using a database of 850 biopsy-proven cases, we compared the performance of our method with a large collection of publicly available state-of-the-art machine learning methods and successfully demonstrated its performance advantage with statistical significance.

    Background: The Black-to-White disparity in breast cancer survival is increasing, and racial residential segregation is a potential driver for this trend. However, study findings have been mixed, and no study has comprehensively compared the effectiveness of different local-level segregation metrics in explaining cancer survival. Methods: We proposed a set of new local segregation metrics named local exposure and isolation (LEx/Is) and compared our new local isolation metric with two related metrics, the location quotient (LQ) and the index of concentration at extremes (ICE), across the 102 largest U.S. metropolitan areas. Then, using case data from the Milwaukee, WI, metropolitan area, we used proportional hazards models to explore associations between segregation and breast cancer survival. Results: Across the 102 metropolitan areas, the new local isolation metric was less skewed than the LQ or ICE. Across all races, Hispanic isolation was associated with poorer all-cause survival, and Hispanic LQ and Hispanic-White ICE were found to be associated with poorer survival for both breast cancer-specific and all-cause mortality. For Black patients, Black LQ was associated with lower all-cause mortality and Black local isolation was associated with reduced all-cause and breast cancer-specific mortality. ICE was found to suffer from high multicollinearity. Conclusions: Local segregation is associated with breast cancer survival, but associations varied based on patient race and metric employed. Impact: We highlight how selection of a segregation measure can alter study findings. These relationships need to be validated in other geographic areas.

    Purpose: The aim of this population-based study was to examine the impact of postmastectomy radiotherapy on the risk of local recurrence in patients with invasive lobular breast cancer (ILC). Methods: The population-based Eindhoven Cancer Registry was used to select all patients with ILC, who underwent mastectomy in five general hospitals in the southern part of Netherlands between 1995 and 2002. Of the 499 patients 383 patients fulfilled the eligibility criteria. Of these patients, 170 (44.4%) had received postmastectomy radiotherapy. The median follow-up was 7.2 years. Fourteen patients (3.7%) were lost to follow-up. Results: During follow-up 22 patients developed a local recurrence, of whom 4 had received postmastectomy radiotherapy. The 5-year actuarial risk of local recurrence was 2.1% for the patients with and 8.7% for the patients without postmastectomy radiotherapy. After adjustment for age at diagnosis, tumour stage and adjuvant systemic treatment, the patients who underwent postmastectomy radiotherapy were found to have a more than 3 times lower risk of local recurrence compared to the patients without (Hazard Ratio 0.30; 95% Confidence Interval: 0.10-0.89). Conclusion: Local control is excellent for patients with ILC who undergo postmastectomy radiotherapy and significantly better than for patients not receiving radiotherapy.

    Purpose: To study pulmonary radiological abnormalities with computer tomography (CT) following different radiotherapy (RT) techniques for breast cancer with respect to regions and density, and their correlation to pulmonary complications and reduction in vital capacity (VC). Methods and Materials: CT scans of the lungs were performed prior to and 4 months following RT in 105 breast cancer patients treated with local or local-regional RT. The radiological abnormalities were analyzed with a CT-adapted modification of a classification system originally proposed by Arriagada, and scored according to increasing density (0-3) and affected lung regions (apical-lateral, central-parahilar, basal-lateral). The highest density grade in each region were added together to form scores ranging from 0-9. The patients were monitored for RT-induced pulmonary complications. VC was measured prior to and 5 months following RT. Results: Increasing CT scores were correlated with both local-regional RT and pulmonary complications (p < 0.001). The mean reduction of VC for patients scoring 4-9 (-202 ml) was larger than for patients scoring 0-3 (-2 ml) (p = 0.035). The effect of confounding factors on the radiological scoring was tested in the local-regional RT group. Scores of 4-9 were less frequently seen in the patients who had received adjuvant chemotherapy prior to RT. The importance of the respective lung regions on the outcome of pulmonary complications was tested. Only radiological abnormalities in the central-parahilar and apical-lateral regions were significantly correlated to pulmonary complications. Discussion: Radiological abnormalities detected on CT images and scored with a modification of Arriagada's classification system can be used as an objective endpoint for pulmonary side effects in breast cancer. The described model should, however, be expanded with information about the volume of lung affected in each region before definite conclusions can be drawn concerning each

    The objectives of this study were to investigate the effects of divided dose electron beam radiation twice a week (with a focal dose of 600 rads at a time) on local recurrent tumors of postoperative breast cancer and to compare it with the conventional photon radiation in the hope that it might be better tolerated by the patients, with less damage to normal skin and lung tissues. Out of 261 patients with breast cancer who came to the Department of Radiology, at Gunma Univ. Hospital, Maebashi, during the period Jan., 1970, through Jun., 1976, 41 patients who received electron beam radiation for local recurrence (in 81 sites) and 31 who received prophylactic radiation over the chest wall postoperatively. Tumors completely disappeared from 73 out of 81 sites irradiated for local recurrence (accounting 90% of the 81 sites). The local recurrent lesions were classified to the ''disseminated'' and the ''focal'' type to compare the effects of the radiation, and it was found that the radiation eliminated the tumors from all (100%) of the 63 sites of the former type, while the radiation was capable of eliminating the tumors from only 10 out of the 18 sites of the latter type (56%). When the focal type tumors were classified by histopathologic typing to compare the effects of the radiation, the radiation was assessed effective in papillotubular carcinoma, medullary tubular carcinoma and scirrhous carcinoma in the decreasing sequence of significance. Pulmonary disorders occurred in 12% of all the observed sites. However, it is possible to further reduce this incidence by the adequate use of the tissue compensating filter, Mix-R. A skin disorder (erosion) was observed in 59% of all the sites observed. However, it may be anticipated that the topical application of a suitable corticoid (Beta-methasone-17-valerate cream) preparation will by prophylactically effective. (auth.)

    To prospectively evaluate the feasibility of 3-D radioguided occult lesion localization (iROLL) and to compare iROLL with wire-guided localization (WGL) in patients with early-stage breast cancer undergoing breast-conserving surgery and sentinel lymph node biopsy (SLNB). WGL (standard procedure) and iROLL in combination with SLNB were performed in 31 women (mean age 65.1 ± 11.2 years) with early-stage breast cancer and clinically negative axillae. Patient comfort in respect of both methods was assessed using a ten point scale. SLNB and iROLL were guided by freehand SPECT (fhSPECT). The results of the novel 3-D image-based method were compared with those of WGL, ultrasound-based lesion localization, and histopathology. iROLL successfully detected the malignant primary and at least one sentinel lymph node in 97 % of patients. In a single patient (3 %), only iROLL, and not WGL, enabled lesion localization. The variability between fhSPECT and ultrasound-based depth localization of breast lesions was low (1.2 ± 1.4 mm). Clear margins were achieved in 81 % of the patients; however, precise prediction of clear histopathological surgical margins was not feasible using iROLL. Patients rated iROLL as less painful than WGL with a pain score 0.8 ± 1.2 points (p < 0.01) lower than the score for iROLL. iROLL is a well-tolerated and feasible technique for localizing early-stage breast cancer in the course of breast-conserving surgery, and is a suitable replacement for WGL. As a single image-based procedure for localization of breast lesions and sentinel nodes, iROLL may improve the entire surgical procedure. However, no advantages of the image-guided procedure were found with regard to prediction of complete tumour resection. (orig.)

    The contemporary goals of breast cancer treatment are not limited to cure but include maximizing quality of life. All breast cancer treatment can adversely affect breast appearance. Developing objective, quantifiable methods to assess breast appearance is important to understand the impact of deformity on patient quality of life, guide selection of current treatments, and make rational treatment advances. A few measures of aesthetic properties such as symmetry have been developed. They are computed from the distances between manually identified fiducial points on digital photographs. However, this is time-consuming and subject to intra- and inter-observer variability. The purpose of this study is to investigate methods for automatic localization of fiducial points on anterior-posterior digital photographs taken to document the outcomes of breast reconstruction. Particular emphasis is placed on automatic localization of the nipple complex since the most widely used aesthetic measure, the Breast Retraction Assessment, quantifies the symmetry of nipple locations. The nipple complexes are automatically localized using normalized cross-correlation with a template bank of variants of Gaussian and Laplacian of Gaussian filters. A probability map of likely nipple locations determined from the image database is used to reduce the number of false positive detections from the matched filter operation. The accuracy of the nipple detection was evaluated relative to markings made by three human observers. The impact of using the fiducial point locations as identified by the automatic method, as opposed to the manual method, on the calculation of the Breast Retraction Assessment was also evaluated.

    Of all the much hyped and pricy cancer drugs, the benefits from the promising siRNA small molecule drugs are limited. Lack of efficient delivery vehicles that would release the drug locally, protect it from degradation, and ensure high transfection efficiency, precludes it from fulfilling its full potential. This work presents a novel platform for local and sustained delivery of siRNA with high transfection efficiencies both in vitro and in vivo in a breast cancer mice model. siRNA protection and high transfection efficiency are enabled by their encapsulation in oligopeptide-terminated poly(β-aminoester) (pBAE) nanoparticles. Sustained delivery of the siRNA is achieved by the enhanced stability of the nanoparticles when embedded in a hydrogel scaffold based on polyamidoamine (PAMAM) dendrimer cross-linked with dextran aldehyde. The combination of oligopeptide-terminated pBAE polymers and biodegradable hydrogels shows improved transfection efficiency in vivo even when compared with the most potent commercially available transfection reagents. These results highlight the advantage of using composite materials for successful delivery of these highly promising small molecules to combat cancer. © 2014 WILEY-VCH Verlag GmbH & Co.

    Su Vida, Su Salud/Your Life, Your Health is a community program to increase participation in breast and cervical cancer screening. This program illustrates the diffusion of an innovative outreach strategy from a research environment to two local health departments. The program uses A Su Salud, the communication model in which positive role models are featured in the media, and community volunteers who give positive social reinforcement. Local health departments in Galveston and Corpus Christi, TX, were selected to implement the model because of excessive mortality rates in the region and the departments' adequate level of resources and commitment. Over an 18-month period, 54 stories of role models appeared in the media in Corpus Christi, and 60 appeared in Galveston. There were 490 volunteers active in Corpus Christi and 279 in Galveston. Of 365 inquiries to the Corpus Christi program, 35 percent were from the Mexican American target group of women ages 40-70. Of 1,457 women who contacted the Galveston program, 9 percent were from the African American target group ages 40-70. Local health departments are well-suited to participation in cancer control research applications because they have direct access to high-risk populations and have the authority to institutionalize effective interventions.

    To evaluate the use of the water-to-fat (W-F) value obtained from in vivo proton ((1)H) MR spectroscopy (MRS) as a response indicator of cytologically confirmed patients with locally advanced breast cancer (LABC), and to monitor the therapeutic response of such patients to neoadjuvant chemotherapy (NACT). Serial (1)H MR spectra were recorded both before and after the completion of chemotherapy in 33 LABC patients (with infiltrating ductal carcinoma (IDC)) at 1.5T. In addition, spectra from normal breast tissues of 28 healthy volunteers were recorded. Malignant breast tissues showed elevated W-F values compared to normal breast tissues of controls. Statistically significant higher pretherapy W-F value (P W-F value showed a decrease that was statistically significant (P W-F value had no correlation with the menstrual status of the patients. A comparison of pretherapy W-F value with pretherapy tumor volume showed a fair correlation (P = 0.05), while the posttherapy W-F value showed no such correlation with the posttherapy tumor volume. This study demonstrates that simple, conventional in vivo (1)H MRS is a useful technique for monitoring the therapeutic response of breast cancer patients. The observed trend in the reduction of W-F value provides a noninvasive response indicator to monitor the clinical outcome of locally advanced breast cancer patients to NACT.

    The purpose of this work was to retrospectively evaluate survival and local control rates of triple-negative breast cancer subtypes classified as five marker negative (5NP) and core basal (CB), respectively, after breast-conserving surgery and intraoperative boost radiotherapy with electrons (IOERT) followed by whole breast irradiation. A total of 71 patients with triple-negative breast cancer were enrolled, who were treated with lumpectomy, axillary lymph node dissection, and IOERT with 9.6 Gy (median D max ) followed by normofractionated whole breast irradiation to median total doses of 54 Gy. Chemotherapy was applied in a neoadjuvant (12 %), adjuvant (75 %), or combinational setting (7 %). After a median follow-up of 97 months (range 4-170 months), 5 in-breast recurrences were detected (7.0 %). For all patients, 8-year actuarial rates for local control, metastases-free survival, disease-specific survival, and overall survival amounted to 89, 75, 80, and 69 %, respectively. All local recurrences occurred in grade 3 (G3) tumors irrespective of their specific immunohistochemical phenotype; thus, the local control rate for grades 1/2 (G1/2) was 100 % for both 5NP and CB, while for G3 it was 88 % for 5NP and 90 % for CB (p = 0.65 and 0.82, respectively, n.s.). For disease-specific survival, only the difference of the best-prognosis group 5-NP/G3 vs. the worst-prognosis cohort CB/G1/2 was statistically significant: 90 % vs. 54 % (p = 0.03). Boost-IOERT provides acceptable long-term in-breast control in triple negative breast cancer. The best subgroup in terms of disease-specific survival was represented by 5NP in combination with tumor grading G3. (orig.) [de

    To assess whether DCE-MRI pharmacokinetic (PK) parameters obtained before and during chemotherapy can predict pathological complete response (pCR) differently for different breast cancer groups. Eighty-four patients who received neoadjuvant chemotherapy for locally advanced breast cancer were retrospectively included. All patients underwent two DCE-MRI examinations, one before (EX1) and one during treatment (EX2). Tumours were classified into different breast cancer groups, namely triple negative (TNBC), HER2+ and ER+/HER2-, and compared with the whole population (WP). PK parameters Ktrans and Ve were extracted using a two-compartment Tofts model. At EX1, Ktrans predicted pCR for WP and TNBC. At EX2, maximum diameter (Dmax) predicted pCR for WP and ER+/HER2-. Both PK parameters predicted pCR in WP and TNBC and only Ktrans for the HER2+. pCR was predicted from relative difference (EX1 - EX2)/EX1 of Dmax and both PK parameters in the WP group and only for Ve in the TNBC group. No PK parameter could predict response for ER+/HER-. ROC comparison between WP and breast cancer groups showed higher but not statistically significant values for TNBC for the prediction of pCR CONCLUSIONS: Quantitative DCE-MRI can better predict pCR after neoadjuvant treatment for TNBC but not for the ER+/HER2- group. • DCE-MRI-derived pharmacokinetic parameters can predict response status of neoadjuvant chemotherapy treatment. • Ktrans can better predict pCR for the triple negative group. • No pharmacokinetic parameter could predict response for the ER+/HER2- group.

    To compare axillary involvement (N+) at initial staging in locally advanced breast cancer (LABC) with axillary lymphadenectomy histologic results after neoadjuvant chemotherapy treatment (NeoChemo). Retrospective study between November 2011 and September 2013 of LABC cases treated with neoadjuvant chemotherapy based on docetaxel (associated with trastuzumab in HER2 positive cases and carboplatin/adriamycin in HER2 negative cases). Those clinically or radiologically suspected cases of axillary involvement were histologically confirmed. When there was no suspicion of axillary involvement, sentinel lymph node radioguided biopsy (SLNRB) was performed using intradermal injection of (99m)Tc-nanocolloid albumin prior to neoadjuvant treatment. Axillary lymphadenectomy after NeoChemo was undertaken in all cases with positive axilla. Final pathologic response was classified as complete (pCR) when there was no evidence of tumoral disease and as non-pathologic complete response (no pCR) in the opposite case. A total of 346 patients treated with docetaxel were reviewed, identifying 105 LABC. Axillary involvement at initial staging was detected in 70 (67%) before starting NeoChemo. From these 70, 73% (n=51) were N+ (fine needle biopsy and/or biopsy) and the remaining 19 (27%) were occult N+ detected by SLNRB. Axillary lymphadenectomy detected pCR in 56% (39/70), increasing up to 84% pCR when initial N+ status was reached using SNLB. On the other hand, when N+ was detected using fine needle biopsy/lymph biopsy, pCR was only 45%. More than 50% of women affected by locally advanced breast cancer with tumoral axillary involvement at initial diagnosis present free metastatic axilla after therapeutic neoadjuvant chemotherapy effect. This increases up to almost 90% in case of occult metastatic axilla detected with sentinel node biopsy prior starting neoadjuvant chemotherapy. Copyright © 2014 Elsevier España, S.L.U. and SEMNIM.

    The local endocrine environment of the breast may have stronger relations to breast cancer risk than systemic hormones. Nipple aspiration fluid (NAF) provides a window into this milieu. We hypothesized that the correlations between proteins and steroid hormones in NAF are stronger, and specific relationships may reveal links to breast cancer risk. NAF and blood samples were obtained simultaneously from 54 healthy women and from the contralateral unaffected breast of 60 breast cancer patients. The abundance of five proteins, superoxide dismutase (SOD1), C-reactive protein (CRP), chitinase-3-like protein 1 (YKL40), cathepsin D (CatD), and basic fibroblast growth factor (bFGF) in NAF was measured using ELISA. The NAF and serum concentrations of estradiol, estrone, progesterone, androstenedione, testosterone, and dehydroepiandrostrerone (DHEA) were measured using ELISA or RIA. The correlations between proteins and hormones revealed that NAF proteins correlated with each other: SOD1 with CRP (R = 0.276, P = 0.033) and CatD (R = 0.340, P = 0.0036), and bFGF with CRP (R = 0.343, P = 0.0021). NAF proteins displayed significant correlations with NAF steroids, but not with serum steroids: SOD1 with DHEA (R = 0.333, P = 0.019), YKL40 with testosterone (R = 0.389, P = 0.0012), and bFGF negatively correlated with testosterone (R = -0.339, P = 0.015). The regulation of YKL40 and bFGF by testosterone was confirmed in breast cancer cell lines. In summary, NAF proteins were more strongly related to local hormone levels than to systematic hormone levels. Some proteins were specifically correlated with different NAF steroids, suggesting that these steroids may contribute to breast cancer risk through different mechanisms.

    Purpose: Vascular endothelial growth factor (VEGF) is an important protein involved in the process of angiogenesis that has been found to correlate with relapse-free and overall survival in breast cancer, predominantly in locally advanced and metastatic disease. A paucity of data is available on the prognostic implications of VEGF in early-stage breast cancer; specifically, its prognostic value for local relapse after breast-conserving therapy (BCT) is largely unknown. The purpose of our study was to assess VEGF expression in a cohort of early-stage breast cancer patients treated with BCT and to correlate the clinical and pathologic features and outcomes with overexpression of VEGF. Methods and Materials: After obtaining institutional review board approval, the paraffin specimens of 368 patients with early-stage breast cancer treated with BCT between 1975 and 2005 were constructed into tissue microarrays with twofold redundancy. The tissue microarrays were stained for VEGF and read by a trained pathologist, who was unaware of the clinical details, as positive or negative according the standard guidelines. The clinical and pathologic data, long-term outcomes, and results of VEGF staining were analyzed. Results: The median follow-up for the entire cohort was 6.5 years. VEGF expression was positive in 56 (15%) of the 368 patients. Although VEGF expression did not correlate with age at diagnosis, tumor size, nodal status, histologic type, family history, estrogen receptor/progesterone receptor status, or HER-2 status, a trend was seen toward increased VEGF expression in the black cohort (26% black vs. 13% white, p = .068). Within the margin-negative cohort, VEGF did not predict for local relapse-free survival (RFS) (96% vs. 95%), nodal RFS (100% vs. 100%), distant metastasis-free survival (91% vs. 92%), overall survival (92% vs. 97%), respectively (all p >.05). Subset analysis revealed that VEGF was highly predictive of local RFS in node-positive, margin

    Despite broad advances in multimodal treatment of locally advanced breast cancer (LABC), 30 to 40% of patients develop loco-regional relapse. The aim of this study was to analyze in a retrospective manner the effectiveness of concurrent chemo-radiotherapy (CCRTh) after neoadjuvant chemotherapy (NCT) in patients with LABC. One hundred twelve patients with LABC (stage IIB-IIIB) were treated with NCT (5-fluorouracil 500 mg/m 2 , doxorubicin 50 mg/m 2 , and cyclophosphamide 500 mg/m 2 (FAC), or doxorubicin 50 mg/m 2 and cyclophosphamide 500 mg/m 2 (AC) IV in four 21-day courses) followed by CCRTh (60 Gy breast irradiation and weekly mitomycin 5 mg/m 2 , 5-fluorouracil 500 mg/m 2 , and dexamethasone 16 mg, or cisplatin 30 mg/m 2 , gemcitabine 100 mg/m 2 and dexamethasone 16 mg), and 6–8 weeks later, surgery and two additional courses of FAC, AC, or paclitaxel 90 mg/m 2 weekly for 12 weeks, and in case of estrogen-receptor positive patients, hormonal therapy. Stages IIB, IIIA and -B were 21.4, 42.9, and 35.7%, respectively. Pathological complete response (pCR) in the breast was 42% (95% CI, 33.2–50.5%) and, 29.5% (95% CI, 21.4–37.5%) if including both the breast and the axillary nodes. Multivariate analysis showed that the main determinant of pCR was negative estrogen-receptor status (HR = 3.8; 95% CI, 1.5–9; p = 0.016). The 5-year disease-free survival (DFS) was 76.9% (95% CI, 68.2–84.7%). No relationship between pCR and DFS was found. Multivariate analysis demonstrated that the main DFS determinant was clinical stage (IIB and IIIA vs. IIIB, HR = 3.1; 95% CI, 1.02–9.74; p = 0.04). Only one patient had local recurrence. Five-year overall survival was 84.2% (95% CI, 75–93.2%). The toxicity profile was acceptable. This non-conventional multimodal treatment has good loco-regional control for LABC. Randomized clinical trials of preoperative CCRTh following chemotherapy, in patients with LABC are warranted

    There is growing evidence of a survival benefit for metastatic breast cancer patients receiving surgery of the primary tumor. We investigated whether or not adjuvant radiotherapy can improve survival. Women diagnosed between 1988 and 2003 with metastatic, histologically confirmed unilateral primary breast cancer were selected from the SEER Program. Overall survival and specific survival were computed by the Kaplan-Meier method. Treatment hazard ratios of breast-conserving surgery or mastectomy versus no surgery, and radiotherapy versus none, were computed by Cox regression adjusting for period of diagnosis, age, marital status, race, histology, grade, and hormone receptors. Of 8761 women, radiotherapy was given to 1473 of 3905 who did not undergo surgery, to 882 of 2070 who underwent breast-conserving surgery, and to 1103 of 2786 mastectomy patients. Median overall survival was: for no surgery, 14 months; for breast-conserving surgery, 23 months; and for mastectomy, 28 months (P < 0.0001). The median overall survival of radiotherapy versus none was respectively 16 vs. 13 months without surgery (P = 0.0003), 28 vs. 20 months for breast-conserving surgery patients (P < 0.0001), and 28 vs. 28 months among mastectomy patients (P = 0.895). Multivariate analysis showed relative mortality reductions of 28% by breast-conserving surgery, 42% by mastectomy, and 10% by radiotherapy. Specific survival showed comparable results. Surgery and radiotherapy were associated with a significant survival advantage. We argue that local therapy should be considered even in metastatic disease.

    A noninvasive computer-aided-theragnosis (CAT) system was developed for the early therapeutic cancer response assessment in patients with locally advanced breast cancer (LABC) treated with neoadjuvant chemotherapy. The proposed CAT system was based on multi-parametric quantitative ultrasound (QUS) spectroscopic methods in conjunction with advanced machine learning techniques. Specifically, a kernel-based metric named maximum mean discrepancy (MMD), a technique for learning from imbalanced data based on random undersampling, and supervised learning were investigated with response-monitoring data from LABC patients. The CAT system was tested on 56 patients using statistical significance tests and leave-one-subject-out classification techniques. Textural features using state-of-the-art local binary patterns (LBP), and gray-scale intensity features were extracted from the spectral parametric maps in the proposed CAT system. The system indicated significant differences in changes between the responding and non-responding patient populations as well as high accuracy, sensitivity, and specificity in discriminating between the two patient groups early after the start of treatment, i.e., on weeks 1 and 4 of several months of treatment. The proposed CAT system achieved an accuracy of 85%, 87%, and 90% on weeks 1, 4 and 8, respectively. The sensitivity and specificity of developed CAT system for the same times was 85%, 95%, 90% and 85%, 85%, 91%, respectively. The proposed CAT system thus establishes a noninvasive framework for monitoring cancer treatment response in tumors using clinical ultrasound imaging in conjunction with machine learning techniques. Such a framework can potentially facilitate the detection of refractory responses in patients to treatment early on during a course of therapy to enable possibly switching to more efficacious treatments.

    The main benefit of neoadjuvant chemotherapy is a reduction in tumor size, which allows breast-conserving surgery (BCS) in patients who otherwise would have required a mastectomy. Breast magnetic resonance (MRI) has been proposed to evaluate tumor extent after neoadjuvant chemotherapy, to determine which patients have become eligible for BCS. The aim of our study was to determine how the association of breast MRI to routine clinical and radiologic assessment of the tumor at initial presentation, and after chemotherapy, affects the overall surgical decision process. 54 women with stage IIB-IIIB breast cancer were prospectively enrolled in a study investigating the effects of MRI on the surgical decision. Surgical plan was changed from BCS to radical mastectomy in 6 cases (13.04%). As a result of using MRI in evaluating disease extent, 21.73% of valuable data were added by MRI (pectoralis major muscle and skin invasion, multifocal multicentric disease). Due to MRI examination 28 (60.86%) of the patients with operable breast cancer after neoadjuvant chemotherapy, were eligible for BCS. Our study demonstrates that MRI is the most accurate in determination of tumor size and extent, and in establishing eligibility for BCS. Celsius.

    The optimal sequence of mastectomy with immediate breast reconstruction (IBR) and radiotherapy (RT) for the treatment of locally advanced breast cancer (LABC) is still under debate. Increased rates of postoperative complications are described following postmastectomy RT. Neoadjuvant RT aims to improve the aesthetic results and simplify the reconstructive pathway. A total of 22 patients diagnosed with LABC and treated with neoadjuvant RT followed by mastectomy and IBR between 04/2012 and 03/2015 were retrospectively analyzed. RT consisted of external beam RT to the breast and the regional lymphatics, if indicated. Both implant-based and autologous tissue-transfer reconstruction techniques were used. At the time of RT, 10 patients had no prior surgery and 12 patients had previously undergone breast-conserving surgery (BCS) with positive resection margins without the possibility to perform a second BCS. Additional neoadjuvant chemotherapy was administered in 18 patients prior to RT. A complete pathological response was achieved in 55.0% of patients. The 2-year overall survival rate was 89.3%, the 2-year disease-free-survival 79.8% and the local-recurrence-free survival was 95.2%. The cosmetic result was excellent or good in 66% of the patients treated with upfront mastectomy and 37% of the patients who had previously undergone BCS. Among patients who received implant-based IBR, 4 patients developed serious wound-healing problems with implant loss. The most satisfactory results were achieved with autologous tissue reconstruction. A sequential neoadjuvant chemo-/radiotherapy to allow IBR following mastectomy in selected cases of LABC seems feasible and can be safely attempted. Careful patient selection, close monitoring, and continuous patient support is mandatory to ensure compliance in this treatment strategy. (orig.)

    In recent years repeat sentinel node (SN) biopsy has been proven to be feasible in local breast cancer recurrence (LBCR). However, in these patients SNs outside the ipsilateral axilla are frequently observed. This study evaluates the contribution of SPECT/CT for SN localization and surgical adjustment in LBCR patients. SN biopsy was performed in 122 LBCR patients (median age 60.5 years, range 24-87), enrolled from August 2006 to July 2015. Median disease-free time lapse was 109.5 months (range 9-365). Axillary lymph node dissection (ALND) had previously been performed in 55 patients, SN biopsy in 44, both techniques in 13 and fine-needle aspiration in 10. Primary breast cancer treatment included radiotherapy in 104 patients (85.3 %) and chemotherapy in 40 (32.8 %). Preoperative lymphatic mapping, using planar scintigraphy (PS) and SPECT/CT included report of SN location according to lymph node territory. In case of a territorial PS-SPECT/CT mismatch, surgery was adjusted according to SPECT/CT findings. SPECT/CT SN visualization rate was higher than PS (53.3 % vs. 43.4 %, p n.s.) with, in total, 19 additional SN (118 vs. 99, p n.s.). PS-SPECT/CT territory mismatch, found in 60 % (39/65) of patients with SN visualization, led to surgical adjustment in 21.3 % (26/122) of patients. The SN procedure was finally performed in 104 patients resulting in a 65.7 % surgical retrieval rate with a total of 132 removed SNs (1.86/patient). SN metastases were found in 17/71 patients (23.9 %), in 16 of them (94 %) in ipsilateral basins outside the axilla or in the contralateral axilla. Using SPECT/CT there is a trend to visualize more SNs in LBCR, providing at the same time important anatomical information to adjust intraoperative SN procedures. The addition of SPECT/CT to the standard imaging protocol may lead to better staging mainly in patients presenting drainage outside the ipsilateral axilla. (orig.)

    Despite federal funding for breast cancer screening, fragmented infrastructure and limited organizational capacity hinder access to the full continuum of breast cancer screening and clinical follow-up procedures among rural-residing women. We proposed a regional hub-and-spoke model, partnering with local providers to expand access across North Texas. We describe development and application of an iterative, mixed-method tool to assess county capacity to conduct community outreach and/or patient navigation in a partnership model. Our tool combined publicly-available quantitative data with qualitative assessments during site visits and semi-structured interviews. Application of our tool resulted in shifts in capacity designation in 10 of 17 county partners: 8 implemented local outreach with hub navigation; 9 relied on the hub for both outreach and navigation. Key factors influencing capacity: (1) formal linkages between partner organizations; (2) inter-organizational relationships; (3) existing clinical service protocols; (4) underserved populations. Qualitative data elucidate how our tool captured these capacity changes. Our capacity assessment tool enabled the hub to establish partnerships with county organizations by tailoring support to local capacity and needs. Absent a vertically integrated provider network for preventive services in these rural counties, our tool facilitated a virtually integrated regional network to extend access to breast cancer screening to underserved women.

    Full Text Available Hereditary breast cancer occurs in 5–20 % of cases and it is associated with inherited mutations in particular genes, such as BRCA1 и BRCA2 in most cases. The CHEK2, PTEN, TP53, ATM, RAD51, BLM, PALB2, Nbs genes are associated with low and median risks ofdeveloping breast cancer. Molecular genetic studies identify germinal mutations underlying hereditary breast cancer. In most cases hereditary breast cancer refers to triple-negative phenotype, which is the most aggressive type of breast cancer, that does not express the genes for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER2. The review presents the diagnostic and treatment methods of hereditary breast cancer. Clinical-morphological aspects allow the new diagnostic and treatment methods of hereditary breast cancer to be identified. Poly (ADP-ribose polymerase (PARP inhibitors demonstrate the potential for effective treatment of BRCA-associated breast cancer.

    Full Text Available Breast cancer in young women tends to have a natural history of aggressive disease for which rates of recurrence are higher than in breast cancers detected later in life. Little is known about the genetic pathways that underlie early-onset breast cancer. Here we report the discovery of DEAR1 (ductal epithelium-associated RING Chromosome 1, a novel gene encoding a member of the TRIM (tripartite motif subfamily of RING finger proteins, and provide evidence for its role as a dominant regulator of acinar morphogenesis in the mammary gland and as an independent predictor of local recurrence-free survival in early-onset breast cancer.Suppression subtractive hybridization identified DEAR1 as a novel gene mapping to a region of high-frequency loss of heterozygosity (LOH in a number of histologically diverse human cancers within Chromosome 1p35.1. In the breast epithelium, DEAR1 expression is limited to the ductal and glandular epithelium and is down-regulated in transition to ductal carcinoma in situ (DCIS, an early histologic stage in breast tumorigenesis. DEAR1 missense mutations and homozygous deletion (HD were discovered in breast cancer cell lines and tumor samples. Introduction of the DEAR1 wild type and not the missense mutant alleles to complement a mutation in a breast cancer cell line, derived from a 36-year-old female with invasive breast cancer, initiated acinar morphogenesis in three-dimensional (3D basement membrane culture and restored tissue architecture reminiscent of normal acinar structures in the mammary gland in vivo. Stable knockdown of DEAR1 in immortalized human mammary epithelial cells (HMECs recapitulated the growth in 3D culture of breast cancer cell lines containing mutated DEAR1, in that shDEAR1 clones demonstrated disruption of tissue architecture, loss of apical basal polarity, diffuse apoptosis, and failure of lumen formation.

    Autologous fat grafting after breast cancer surgery is commonly performed, but concerns about oncologic risk remain. To model the interaction between fat grafting and breast cancer cells, two approaches were employed. In the first approach, graded numbers of viable MDA-MB-231 or BT-474 cells were admixed directly into human fat grafts and injected subcutaneously into immune-deficient mice to determine if the healing graft is a supportive environment for the tumor. In the second approach, graded doses of MDA-MB-231 cells were suspended in Matrigel and injected into the mammary fat pads of mice. Two weeks after the tumor cells engrafted, 100 μL of human adipose tissue was grafted into the same site. Histologically, MDA-MB-231 cells seeded within fat grafts were observed and stained positive for human-specific pan-cytokeratin and Ki67. The BT-474 cells failed to survive when seeded within fat grafts at any dose. In the second approach, MDA-MB-231 cells had a strong trend toward lower Ki67 staining at all doses. Regression analysis on all groups with fat grafts and MDA-MB-231 revealed fat tissue was associated with lower cancer cell Ki67 staining. Healing fat grafts do not support the epithelial BT-474 cell growth, and support the mesenchymal MDA-MB-231 cell growth only at doses ten times greater than in Matrigel controls. Moreover, fat grafts in association with MDA-MB-231 cancer cells already present in the wound resulted in decreased tumor proliferation and increased fibrosis. These findings suggest that clinical fat grafting does not induce breast cancer cell growth, and may even have a suppressive effect.

    The patient was a 39-year-old woman who was referred to our hospital with suspicion of locally-advanced breast cancer. After several tests, she received a diagnosis of cT4bN1M1 (liver), Stage Ⅳbreast cancer. The liver metastasis was located in S4, and was 1 cm in size. Core needle biopsy was performed on the breast tumor; the pathological diagnosis was invasive ductal carcinoma (scirrhous carcinoma), nuclear Grade (NG) 3, and HER2-positive. She received epirubicin plus cyclophosphamide (EC) followed by docetaxel (DOC) plus pertuzumab (PER) plus trastuzumab (HER). After chemotherapy, the liver metastasis and axillary lymph node metastases had disappeared on imaging findings, showing a complete response (CR), but the primary breast tumor remained, showing a partial response (PR). She underwent mastectomy and axillary lymph node dissection for local control. After surgery, no metastases including liver metastases were seen on CT. The patient is currently receiving tamoxifen and anti-HER2 therapy.

    2011-05-01

    Conventional mammography is a screening procedure constrained by low specificity in the detection of breast cancer. Approximately 40% of women undergoing mammography screening have dense breast tissue, and conventional mammographic imaging has a sensitivity range of only 50%-85% for malignant lesions. Magnetic resonance imaging (MRI) is now recommended for breast cancer screening in high-risk patients. However, approximately 15% of patients cannot tolerate MRI. These are the clinical situations in which positron emission mammography (PEM) and breast-specific gamma (BSG) camera systems fulfill a need for primary breast cancer imaging. Because breast cancer is the most common malignancy and the second most common cause of cancer death among women, many nuclear medicine imaging techniques are essential in the evaluation and therapy of patients with this disease. Nuclear medicine surgical techniques consist of sentinel lymph node localization and the use of radiolabeled seeds for intraoperative localization of nonpalpable breast cancers. The Food and Drug Administration (FDA) has approved the PEM Flex Solo II scanner, which has the capability for stereotactic biopsy, with an array of pixelated lutetium yttrium orthosilicate (LYSO) crystals, position-sensitive photomultiplier tubes (PS-PMT), and a spatial resolution of 2.4 mm. Clear PEM is a scanner in development with cerium-doped LYSO (LYSO:Ce) crystals, multipixel avalanche photodiodes, depth of interaction measurement with a resolution of 1.3 mm. The Dilon 6800 Gamma Camera is a BSG device approved by the FDA with stereotactic biopsy guidance capability, a pixelated array of sodium iodide crystals, PS-PMTs, and an extrinsic spatial resolution of 6 mm at 3 cm from the camera.

    Extensive studies have confirmed the efficacy of taxanes in combination with anthracycline-based chemotherapy on breast cancer. However, few studies have assessed the efficacy of weekly taxane-anthracycline regimens on locally advanced breast cancer. This study was to compare the efficacy and safety of a weekly taxane-anthracycline regimen with those of tri-weekly anthracycline-based regimen in patients with locally advanced breast cancer. Patients with locally advanced breast cancer were randomized to receive 4-6 cycles of neoadjuvant chemotherapy with tri-weekly 5-fluorouracil-epirubicin-cyclophosphamide (FEC) regimen or weekly paclitaxel-epirubicin (PE) regimen. The primary endpoint was the pathologic complete response (pCR) rate. Other endpoints included the clinical tumor response, breast-conserving surgery rate, and adverse events. Between March 2010 and September 2013, 293 patients were randomized to the FEC (n = 151) and PE (n = 142) arms. The overall clinical response rate was significantly higher in the PE arm than in the FEC arm (76.06% vs. 59.95%, P = 0.001). Consistently, the post-chemotherapy pathologic T and N stages were significantly lower in the PE arm than in the FEC arm (P breast-conserving surgery. Most adverse events were comparable in both arms, with more severe neutropenia in the PE arm than in the FEC arm (11.97% vs. 5.96%, P = 0.031). In patients with locally advanced breast cancer, weekly PE was not superior to FEC in terms of pCR. However, weekly PE has a higher response rate and superior down-staging effects. On this account, the PE regimen may be considered an alternative option for locally advanced breast cancer. Long-term follow-up data are needed to confirm the efficacy of this regimen on locally advanced breast cancer.

    2017-11-01

    Locoregional recurrence (LRR) after adequate treatment of primary breast cancer poses a therapeutic challenge. Advances in the management of breast cancer have led to significant improvements in survival. With this advantage, it is observed that the incidence of LRR has relatively decreased. Systemic involvement should be ruled out in patients presenting with locoregionally recurrent disease, as isolated LRR requires a treatment with curative intent. Salvage mastectomy following ipsilateral breast tumor recurrence is a time-tested treatment option and widely accepted. Second-time breast conservation surgery with or without radiotherapy is an emerging alternative. Following a second breast conservation, partial breast irradiation has been seen to improve local control. Five-year overall survival with second breast conservation and radiotherapy is in the range of 76% to 100% with acceptable toxicities. Isolated chest wall recurrences after mastectomy are difficult to manage. Multimodality treatment has been adopted to treat chest wall recurrences, following which the 5-year overall survival was observed to be in the range of 45% to 60%. Use of hyperthermia and photodynamic therapy in combination with conventional treatment options has been associated with better clinical outcomes. Systemic therapy, in the form of chemotherapy and/or hormonal therapy in addition to adequate locoregional treatment, has shown to improve survival. Multimodality treatment for isolated regional recurrences has been associated with better outcomes, and the 5-year survival rates are around 50%. All patients with LRR should be evaluated by a multi-disciplinary tumor board to individualize treatment based on the expected risk-benefit ratio of retreatment. Copyright © 2017 Elsevier Inc.

    2005-01-01

    Purpose: The management of unresectable locally advanced breast cancer (ULABC) remains a major challenge because of the necessity both to treat local disease and to prevent distant disease. Two consecutive Phase I/II trials of concomitant chemotherapy and radiation (CRT) were performed to attempt to address both local and distant disease control in ULABC. This analysis focuses on rates of locoregional control and radiation-associated acute and late complications. Methods and materials: Thirty-three patients with unresectable locally advanced or inflammatory breast cancers (T4N0-3M0-1) or locally recurrent disease were treated with CRT on two consecutive Phase I/II trials. Radiotherapy consisted of 60-70 Gy to the breast or chest wall and 60 Gy to draining lymphatics in a week-on/week-off (WO/WO) schedule. Chemotherapy consisted of either continuous infusion or bolus paclitaxel ± vinorelbine. A subset analysis of 16 patients with nonmetastatic ULABC Stage IIIB-C (T4N0-3M0) was performed. Among this cohort, 13 patients (81%) underwent planned mastectomy after CRT. Results: Of the 16 patients with Stage IIIB-C disease, acute toxicity included moist desquamation (n = 8) and Grade 3-4 neutropenia (n = 3). Late toxicity included breast reconstruction loss, decreased range of arm motion, lymphedema, and skin toxicity, although none was life-threatening. Of 15 assessable patients, 14 had a clinical response, 7 had a pathologic complete response (pCR) including 6 of 13 patients undergoing mastectomy. With a median follow-up for living patients of 43.8 months, the 4-year actuarial locoregional control, disease-free survival, and overall survival were 83%, 33%, and 56% respectively. Conclusions: Concurrent WO/WO radiation therapy and paclitaxel ± vinorelbine is effective locoregional therapy for ULABC with an acceptable toxicity profile. Further investigation of concurrent chemoradiotherapy in ULABC is warranted

    A non-invasive computer-aided-theragnosis (CAT) system was developed for the early assessment of responses to neoadjuvant chemotherapy in patients with locally advanced breast cancer. The CAT system was based on quantitative ultrasound spectroscopy methods comprising several modules including feature extraction, a metric to measure the dissimilarity between "pre-" and "mid-treatment" scans, and a supervised learning algorithm for the classification of patients to responders/non-responders. One major requirement for the successful design of a high-performance CAT system is to accurately measure the changes in parametric maps before treatment onset and during the course of treatment. To this end, a unified framework based on Hilbert-Schmidt independence criterion (HSIC) was used for the design of feature extraction from parametric maps and the dissimilarity measure between the "pre-" and "mid-treatment" scans. For the feature extraction, HSIC was used to design a supervised dictionary learning (SDL) method by maximizing the dependency between the scans taken from "pre-" and "mid-treatment" with "dummy labels" given to the scans. For the dissimilarity measure, an HSIC-based metric was employed to effectively measure the changes in parametric maps as an indication of treatment effectiveness. The HSIC-based feature extraction and dissimilarity measure used a kernel function to nonlinearly transform input vectors into a higher dimensional feature space and computed the population means in the new space, where enhanced group separability was ideally obtained. The results of the classification using the developed CAT system indicated an improvement of performance compared to a CAT system with basic features using histogram of intensity.

    Full Text Available Background: Locally advanced breast cancer (LABC remains major clinical issue with regard to selection and duration of therapy since many years. Neoadjuvant chemotherapy (NACT is multimodality program, established to treat LABC. Many research tasks are ongoing to develop specific neoadjuvant chemotherapy regimen with specific duration to improve long-term control of LABC. Patients and Methods: Forty-seven patients diagnosed with LABC were Included and analyzed to compare the outcomes [pathological complete response (pCR, clinical response, overall response rate (ORR, disease control rate, overall survival and progression-free survival]. These patients treated with either combination of anthracycline and taxane-based chemotherapy or anthracycline-based chemotherapy. Results: There was no any statistical significance with respect to demographic data treated of patients between two arms (P > 0.05. Patients underwent TAC chemotherapy had pCR 20.8% whereas FAC/FEC chemotherapy patients had pCR 13% (P = 0.48. Higher ORR was noted in TAC chemotherapy arm (75% when compared with FAC/FEC chemotherapy arm (60.9% (P = 0.29. The study also shows better disease control rate in TAC chemotherapy arm (95.8% as compared to FAC/FEC chemotherapy arm (82.6%. There was no statistical significance in overall survival (P = 0.31 and progression-free survival (P = 0.51 between two arms. Conclusion: Despite of the superiority of combination of anthracycline and taxane-based chemotherapy over the anthracycline-based chemotherapy in the present study, further pivotal studies should be conducted to confirm the combination of anthracycline and taxane-based chemotherapy as a better neoadjuvant regimen for treatment of LABC tumors.

Results We applied this flap in 12 women (mean age, 56.1 years after WLE (mean specimen weight, 46.5 g of the medial aspect of the breast. Over a median follow-up of 35.3 months (standard deviation, 1.2 months, 4 women needed repeated surgery for dog-ear correction of the donor site. Conclusions In our experience, the use of an IMAP flap was a reliable technique with good cosmetic outcomes after oncoplastic reconstruction. In this series, donor site revision often proved necessary initially, but we showed that this may easily be prevented.

    Purpose: Vascular endothelial growth factor (VEGF) is an important protein involved in the process of angiogenesis that has been found to correlate with relapse-free and overall survival in breast cancer, predominantly in locally advanced and metastatic disease. A paucity of data is available on the prognostic implications of VEGF in early-stage breast cancer; specifically, its prognostic value for local relapse after breast-conserving therapy (BCT) is largely unknown. The purpose of our study was to assess VEGF expression in a cohort of early-stage breast cancer patients treated with BCT and to correlate the clinical and pathologic features and outcomes with overexpression of VEGF. Methods and Materials: After obtaining institutional review board approval, the paraffin specimens of 368 patients with early-stage breast cancer treated with BCT between 1975 and 2005 were constructed into tissue microarrays with twofold redundancy. The tissue microarrays were stained for VEGF and read by a trained pathologist, who was unaware of the clinical details, as positive or negative according the standard guidelines. The clinical and pathologic data, long-term outcomes, and results of VEGF staining were analyzed. Results: The median follow-up for the entire cohort was 6.5 years. VEGF expression was positive in 56 (15%) of the 368 patients. Although VEGF expression did not correlate with age at diagnosis, tumor size, nodal status, histologic type, family history, estrogen receptor/progesterone receptor status, or HER-2 status, a trend was seen toward increased VEGF expression in the black cohort (26% black vs. 13% white, p = .068). Within the margin-negative cohort, VEGF did not predict for local relapse-free survival (RFS) (96% vs. 95%), nodal RFS (100% vs. 100%), distant metastasis-free survival (91% vs. 92%), overall survival (92% vs. 97%), respectively (all p >.05). Subset analysis revealed that VEGF was highly predictive of local RFS in node-positive, margin

    In order to automatically identify a set of effective mammographic image features and build an optimal breast cancer risk stratification model, this study aims to investigate advantages of applying a machine learning approach embedded with a locally preserving projection (LPP) based feature combination and regeneration algorithm to predict short-term breast cancer risk. A dataset involving negative mammograms acquired from 500 women was assembled. This dataset was divided into two age-matched classes of 250 high risk cases in which cancer was detected in the next subsequent mammography screening and 250 low risk cases, which remained negative. First, a computer-aided image processing scheme was applied to segment fibro-glandular tissue depicted on mammograms and initially compute 44 features related to the bilateral asymmetry of mammographic tissue density distribution between left and right breasts. Next, a multi-feature fusion based machine learning classifier was built to predict the risk of cancer detection in the next mammography screening. A leave-one-case-out (LOCO) cross-validation method was applied to train and test the machine learning classifier embedded with a LLP algorithm, which generated a new operational vector with 4 features using a maximal variance approach in each LOCO process. Results showed a 9.7% increase in risk prediction accuracy when using this LPP-embedded machine learning approach. An increased trend of adjusted odds ratios was also detected in which odds ratios increased from 1.0 to 11.2. This study demonstrated that applying the LPP algorithm effectively reduced feature dimensionality, and yielded higher and potentially more robust performance in predicting short-term breast cancer risk.

    Long-term local control rates were studied in a series of 659 patients with invasive breast cancer aged 40 years or younger, who underwent mastectomy in general hospitals in the southern part of the Netherlands between 1988 and 2005. During a median follow-up time of 6.0 years, 34 patients developed a local recurrence in the chest wall without previous or simultaneous evidence of distant disease. The 5- and 10-year actuarial local recurrence rates for the total group were 5.6% (95% confidence interval [95% CI], 3.5-7.7%) and 7.3% (95% CI, 4.7-9.9%), respectively. A multivariate analysis showed that patients receiving radiotherapy (hazards ratio [HR], 0.29; 95% CI, 0.10-0.96) or adjuvant systemic treatment (HR 0.23; 95% CI, 0.08-0.65) had a significantly lower risk of local recurrence. It is concluded that excellent local control rates can be obtained with mastectomy in young women with breast cancer, especially in those who receive adjuvant systemic treatment and/or radiotherapy.

    Full Text Available Abstract Background Complementary and alternative medicine (CAM use is common among cancer patients. This paper reviews the use of CAM in a series of patients with locally advanced breast cancer (LABC. Methods Women with LABC attending a specialist clinic at a single Canadian cancer centre were identified and approached. Participants completed a self-administered survey regarding CAM usage, beliefs associated with CAM usage, views of their risks of developing recurrent cancer and of dying of breast cancer. Responses were scored and compared between CAM users and non-users. Results Thirty-six patients were approached, 32 completed the questionnaire (response rate 89%. Forty-seven percent of LABC patients were identified as CAM users. CAM users were more likely to be younger, married, in a higher socioeconomic class and of Asian ethnicity than non-users. CAM users were likely to use multiple modalities simultaneously (median 4 with vitamins being the most popular (60%. Motivation for CAM therapy was described as, "assisting their body to heal" (75%, to 'boost the immune system' (56% and to "give a feeling of control with respect to their treatment" (56%. CAM therapy was used concurrently with conventional treatment in 88% of cases, however, 12% of patients felt that CAM could replace their conventional therapy. Psychological evaluation suggests CAM users perceived their risk of dying of breast cancer was similar to that of the non-Cam group (33% vs. 35%, however the CAM group had less severe anxiety and depression. Conclusion The motivation, objectives and benefits of CAM therapy in a selected population of women with LABC are similar to those reported for women diagnosed with early stage breast cancer. CAM users display less anxiety and depression and are less likely to believe they will die of their breast cancer. However the actual benefit to overall and disease free survival has yet to be demonstrated, as well as the possible interactions with

    Purpose: To investigate whether the expression of p53 binding protein 1 (53BP1) has prognostic significance in a cohort of early-stage breast cancer patients treated with breast-conserving surgery and radiotherapy (BCS+RT). Methods and Materials: A tissue microarray of early-stage breast cancer treated with BCS+RT from a cohort of 514 women was assayed for 53BP1, estrogen receptor, progesterone receptor, and HER2 expression by immunohistochemistry. Through log–rank tests and univariate and multivariate models, the staining profile of each tumor was correlated with clinical endpoints, including ipsilateral breast recurrence–free survival (IBRFS), distant metastasis–free survival (DMFS), cause-specific survival (CSS), recurrence-free survival (RFS), and overall survival (OS). Results: Of the 477 (93%) evaluable tumors, 63 (13%) were scored as low. Low expression of 53BP1 was associated with worse outcomes for all endpoints studied, including 10-year IBRFS (76.8% vs. 90.5%; P=.01), OS (66.4% vs. 81.7%; P=.02), CSS (66.0% vs. 87.4%; P<.01), DMFS (55.9% vs. 87.0%; P<.01), and RFS (45.2% vs. 80.6%; P<.01). Multivariate analysis incorporating various clinico-pathologic markers and 53BP1 expression found that 53BP1 expression was again an independent predictor of all endpoints (IBRFS: P=.0254; OS: P=.0094; CSS: P=.0033; DMFS: P=.0006; RFS: P=.0002). Low 53BP1 expression was also found to correlate with triple-negative (TN) phenotype (P<.01). Furthermore, in subset analysis of all TN breast cancer, negative 53BP1 expression trended for lower IBRFS (72.3% vs. 93.9%; P=.0361) and was significant for worse DMFS (48.2% vs. 86.8%; P=.0035) and RFS (37.8% vs. 83.7%; P=.0014). Conclusion: Our data indicate that low 53BP1 expression is an independent prognostic indicator for local relapse among other endpoints in early-stage breast cancer and TN breast cancer patients treated with BCS+RT. These results should be verified in larger cohorts of patients to validate their

    Different radiotherapy techniques are being used for chest wall irradiation after mastectomy. We review our results with the electron-beam-rotation technique in a series of 130 high risk breast cancer patients. The main end point of the study was local tumour control; secondary end points were disease free survival, and overall survival, as well as acute and late side effects. From January 1990 to June 1995, 89 patients underwent electron-beam-rotation irradiation of the chest wall after primary mastectomy and axillary lymph node dissection (group 1) and 41 patients after excision of local recurrent breast cancer (group II) with 4x2.5 Gy/week to 50 Gy total dose (4-12 MeV electrons depending on the thickness of the chest wall). In addition, irradiation of local-regional lymph nodes and/or a local boost of 10 Gy were applied dependent on the resection and node status. After a median follow up of 29 months (65% stadium III/IV) the 3 year local tumour control, disease free survival, and overall survival were 23%, 47%, and 75%, respectively. Local control in group I was 78% versus 60% in group 11. Significant predictors for local tumour control, disease free survival, and overall survival were resection status (RO versus RI/2) and estrogen receptor status (positive versus negative). In group 1, tumour grading, (GI-IIa versus GIIb-III) and estrogen receptor status were found to be additional significant prognostic factors for complete resected tumours. Five patients developed symptomatic pneumonitis (< 4%) and one patient developed a chronic fistula at the resection. A significant correlation between the degree of acute skin reaction and persistent pigmentation was observed. In high risk breast cancer patients postoperative irradiation with the electron-beam-rotation technique of the chest wall is an effective therapy resulting in 78% local tumour control at 3 years for locally advanced breast cancer and 60 % for recurrent disease. The rate of acute and late toxicity is

    Purpose: To evaluate the local control rate and complications of a single fraction of high-dose-rate brachytherapy (HDR BT) boost in women aged 45 yeas and younger after breast-conserving therapy. Methods and Materials: Between 1999 and 2007, 167 patients between the ages of 26 and 45 years old (72 were 40 years old or younger), with stages T1 to T2 invasive breast cancer with disease-free margin status of at least 5 mm after breast-conserving surgery received 46 to 50 Gy whole-breast irradiation plus a 7-Gy HDR-BT boost (“fast boost”). An axillary dissection was performed in 72.5% of the patients and sentinel lymph node biopsy in 27.5%. A supraclavicular area was irradiated in 19% of the patients. Chemotherapy was used in 86% of the patients and hormone treatment in 77%. Clinical nodes were present in 18% and pathological nodes in 29%. The pathological stage was pT0: 5%, pTis: 3%, pT1: 69% and pT2: 23%. Intraductal component was present in 40% and 28% were G3. Results: At a median follow-up of 92 months, 9 patients relapsed on the margin of the implant, and 1 patient in another quadrant, resulting in a 10-year local relapse rate of 4.3% and a breast relapse rate of 4.9%, with breast preservation in 93.4%; no case of mastectomy due to poor cosmesis arose. Actuarial 5- and 10-year disease-free, cause-specific, and overall survival rates were 87.9% and 85.8%, and 92.1% and 88.4%, and 92.1% and 87.3%, respectively. In a univariate analysis, triple-negative cases and negative hormone receptors did worse, but in a multivariate analysis, only the last factor was significant for local and breast control. Asymptomatic fibrosis G2 was recorded in 3 cases, and there were no other late complications. Cosmetic results were good to excellent in 97% of cases. Conclusions: A single dose of 7 Gy using the fast-boost technique is well tolerated, with a low rate of late complications and improved local tumor control in women aged 45 and younger, compared to published data

    Full Text Available In the normal breast, cellular structures change cyclically in response to ovarian hormones. Cell proliferation, apoptosis, invasion, and differentiation are integral processes that are precisely regulated. Normal epithelial cells depend on the formation of intercellular adhesion contacts to form a continuous sheet of stratifying cell layers that are attached to one and other horizontally and vertically. Cells migrate by extending membrane protrusions to explore the extracellular space locating their targets in a chemotactic manner. The formation of cell protrusions is driven by the assembly of actin filaments at the leading edge. Reorganisation is regulated by a highly integrated signalling cascade that transduces extracellular stimuli to the actin filaments. This signalling cascade is governed by GTPases which act as molecular switches leading to actin polymerisation and the formation of filopodia and lamellipodia. This process is linked to downstream molecules known collectively as WASP proteins, which, in the presence of cortactin, form a complex leading to nucleation and formation of branched filaments. In breast cancer, the cortactin is over expressed leading to increased cellular motility and invasiveness. This hugely complex and integrated signalling cascade transduces extracellular stimuli. There are multiple genes related to cell motility which are dysregulated in human breast cancers.

    Summary Background The oral formulation of vinorelbine together with capecitabine allows for an all-oral combination chemotherapy which promises to raise quality of life of patients with advanced breast cancer. Patients and Methods Patients with HER2-negative, locally advanced, inoperable or metastatic breast cancer were included in this prospective observational trial (treatment schedule: capecitabine 500 mg/m2 twice daily, days 1-14; vinorelbine 60 mg/m2, days 1+8; repeated in 3-week cycles). Results All 32 patients (median age 50 years) were evaluable for toxicity, and 30 patients for response. Twentyfour patients received therapy as first-line treatment, and 8 patients as beyond first-line treatment. Median time to progression was 8 months, and median overall survival was 32 months. Complete response was observed in 1 patient (3%), partial response in 10 patients (33%), and disease stabilization for more than 6 months (SD > 6) in 10 patients (33%). This results in an overall response rate (ORR) of 37% and a clinical benefit rate (ORR + SD > 6) of 70%. The only grade 3/4 toxicities were neutropenia (19%) and hand-foot syndrome (9%). Conclusions The all-oral combination of capecitabine/vinorelbine at this schedule appears to be an effective, well-tolerated regimen for treatment of advanced breast cancer, and offers a promising alternative to single-agent capecitabine and vinorelbine as well as intravenous polychemotherapy.

    This paper explores the ways in which technological innovation becomes adopted and incorporated into healthcare practice. Drawing upon the notion of 'field of practices', we examine how adoption is subject to spatially and temporally distributed reconfigurations across a multi-level set of practices, ranging from the policy level to the micro-level setting of individual action. The empirical backdrop is provided by a case study of the adoption of Breast Lymph Node Assay (BLNA), a diagnostic technology innovation for the treatment of breast cancer patients. Our aim is to contribute to the development of a more comprehensive analysis of the processes surrounding the adoption and incorporation of complex healthcare technologies into routine practice.

    There is a debate on the role of adjuvant Radiotherapy (RT) in elderly breast cancer patients. The aim is to study Quality of Life (QL) throughout the treatment and follow-up periods in early stages breast cancer patients who have started radiotherapy, and to compare the QL of axillary surgery groups. 173 patients, ≥65 years completed the EORTC QLQ-C30 and QLQ-BR23, and the Interview for Deterioration in Daily Living Activities in Dementia(IDDD) questionnaires three times throughout treatment and follow-up periods. Linear mixed effect models were used to evaluate longitudinal changes in QL, and whether these changes differed among axillary surgery groups. QL scores were high (>70/100 points) in most QL areas, with moderate limitations (>30) in sexual functioning and enjoyment, future perspective and global QL. In six areas there was a decline at the RT sessions end, that after 6 weeks was recovered. For three areas, there was an improvement in the follow-up measurement compared to the previous assessments. Changes in seven areas were <5 points. Axillary node dissection patients had a body image decrease (6 points) in the follow up period. The lymphadenectomy group had more fatigue (10 points, p = 0.078) than the other two axillary surgery groups. Results orientate towards good patients' adaptation to their disease and treatments, and to administering RT in early stages breast cancer patients. QL differences between the axillary surgery groups and in their evolutions were few but have appeared in key QL areas. Copyright © 2015 Elsevier Ltd. All rights reserved.

  1. Mammographic detection of breast cancer

    International Nuclear Information System (INIS)

    Homer, M.J.

    1982-01-01

    Mammography, whether film or xerography, is a complementary examination to breast palpation in the detection of breast cancer. According to the guidelines of the American Cancer Society, mammography should be performed on every asymptomatic woman, at least once, over the age of 35. Annual mammography after 50 is also advised. The radiation dose to the breast from current equipment is so low as to not be considered a factor in denying a woman this screening examination. Mammography has a role in evaluating the woman with solitary and multiple breast masses. It is the only proved reliable modality able to detect nonpalpable breast cancers and small tumors less than 2 cm in size. All nonpalpable lesions should be excised by directed biopsy, using a preoperative localization technique

    With improved prognosis due to advances in the diagnosis and therapy of breast cancer, physicians and therapists now focus on aspects such as quality of life and the management of side effects from breast cancer treatment. Therapy- and disease-related side effects often reduce the patientʼs quality of life and can place a further burden on patients, with non-compliance or discontinuation of therapy a potential consequence. Study data have shown that therapy- and disease-related side effects can be reduced using the methods of integrative medicine. Reported benefits include improving patientsʼ wellbeing and quality of life, reducing stress, and improving patientsʼ mood, sleeping patterns and capacity to cope with disease. Examining the impact of integrative medicine on the side effects of cancer treatment would be beyond the scope of this review. This article therefore looks at short-term side effects of cancer treatment which are usually temporary and occur during or after local and systemic therapy. The focus is on mind-body medicine, acupuncture and classic naturopathic treatments developed by Sebastian Kneipp as complementary therapies. The latter includes hydrotherapy, phytotherapy, nutritional therapy, exercise therapy and a balanced lifestyle. PMID:26257404

    This study evaluates acute toxicity outcomes in breast cancer patients treated with adjuvant proton beam therapy (PBT). From 2011 to 2016, 91 patients (93 cancers) were treated with adjuvant PBT targeting the intact breast/chest wall and comprehensive regional nodes including the axilla, supraclavicular fossa, and internal mammary lymph nodes. Toxicity was recorded weekly during treatment, one month following treatment, and then every 6months according to the Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Charts were retrospectively reviewed to verify toxicities, patient parameters, disease and treatment characteristics, and disease-related outcomes. Median follow-up was 15.5months. Median PBT dose was 50.4 Gray relative biological effectiveness (GyRBE), with subsequent boost as clinically indicated (N=61, median 10 GyRBE). Chemotherapy, when administered, was given adjuvantly (N=42) or neoadjuvantly (N=46). Grades 1, 2, and 3 dermatitis occurred in 23%, 72%, and 5%, respectively. Eight percent required treatment breaks owing to dermatitis. Median time to resolution of dermatitis was 32days. Grades 1, 2, and 3 esophagitis developed in 31%, 33%, and 0%, respectively. PBT displays acceptable toxicity in the setting of comprehensive regional nodal irradiation. Copyright © 2017. Published by Elsevier B.V.

    A small, but important, percentage of breast cancer cases is caused by the inheritance of a single copy of a mutated gene. BRCA1 and BRCA2 are the genes most commonly associated with inherited breast cancer; however, mutations in TP53 and PTEN cause Li-Fraumeni syndrome and Cowden syndrome, respectively, both of which are associated with high lifetime risks of breast cancer. Advances in the field of breast cancer genetics have led to an improved understanding of detection and prevention strategies. More recently, strategies to target the underlying genetic defects in BRCA1- and BRCA2-associated breast and ovarian cancers are emerging and may have implications for certain types of sporadic breast cancer.

    To synthesize a fluorescent Her2-NLP peptide conjugate consisting of Her2/neu targeting peptide and nuclear localization sequence peptide (NLP) and assess its cellular uptake and intracellular localization for radionuclide cancer therapy targeting Her2/neu-positive circulating breast cancer cells (CBCC). Fluorescent Cy5.5 Her2-NLP peptide conjugate was synthesized by coupling a bivalent peptide sequence, which consisted of a Her2-binding peptide (NH2-GSGKCCYSL) and an NLP peptide (CGYGPKKKRKVGG) linked by a polyethylene glycol (PEG) chain with 6 repeating units, with an activated Cy5.5 ester. The conjugate was separated and purified by HPLC and then characterized by Maldi-MS. The intracellular localization of fluorescent Cy5.5 Her2-NLP peptide conjugate was assessed by fluorescent microscopic imaging using a confocal microscope after incubation of Cy5.5-Her2-NLP with Her2/neu positive breast cancer cells and Her2/neu negative control breast cancer cells, respectively. Fluorescent signals were detected in cytoplasm of Her2/neu positive breast cancer cells (SKBR-3 and BT474 cell lines), but not or little in cytoplasm of Her2/neu negative breast cancer cells (MDA-MB-231), after incubation of the breast cancer cells with Cy5.5-Her2-NLP conjugates in vitro. No fluorescent signals were detected within the nuclei of Her2/neu positive SKBR-3 and BT474 breast cancer cells, neither Her2/neu negative MDA-MB-231 cells, incubated with the Cy5.5-Her2-NLP peptide conjugates, suggesting poor nuclear localization of the Cy5.5-Her2-NLP conjugates localized within the cytoplasm after their cellular uptake and internalization by the Her2/neu positive breast cancer cells. Her2-binding peptide (KCCYSL) is a promising agent for radionuclide therapy of Her2/neu positive breast cancer using a β(-) or α emitting radionuclide, but poor nuclear localization of the Her2-NLP peptide conjugates may limit its use for eradication of Her2/neu-positive CBCC using I-125 or other Auger electron

    Purpose: To assess the need for adjuvant radiotherapy following mastectomy for patients with node-negative breast tumors 5 cm or larger. Methods and Materials: Between 1981 and 2002, a total of 70 patients with node-negative breast cancer and tumors 5 cm or larger were treated with mastectomy and adjuvant systemic therapies but without radiotherapy at three institutions. We retrospectively assessed rates and risk factors for locoregional failure (LRF), overall survival (OS), and disease-free survival (DFS) in these patients. Results: With a median follow-up of 85 months, the 5-year actuarial LRF rate was 7.6% (95% confidence interval, 3%-16%). LRF was primarily in the chest wall (4/5 local failures), and lymphatic-vascular invasion (LVI) was statistically significantly associated with LRF risk by the log-rank test (p = 0.017) and in Cox proportional hazards analysis (p 0.038). The 5-year OS and DFS rates were 83% and 86% respectively. LVI was also significantly associated with OS and DFS in both univariate and multivariate analysis. Conclusions: This series demonstrates a low LRF rate of 7.6% among breast cancer patients with node-negative tumors 5 cm and larger after mastectomy and adjuvant systemic therapy. Our data indicate that further adjuvant radiation therapy to increase local control may not be indicated by tumor size alone in the absence of positive lymph nodes. LVI was significantly associated with LRF in our series, indicating that patients with this risk factor require careful consideration with regard to further local therapy

    Purpose: To evaluate whether local recurrence (LR) risk has changed over time among women with stage I breast cancer treated with breast-conserving therapy. Methods and Materials: Subjects were 5974 women aged ≥50 years diagnosis with pT1N0 breast cancer from 1989 to 2006, treated with breast-conserving surgery and radiation therapy. Clinicopathologic characteristics, treatment, and LR outcomes were compared among 4 cohorts stratified by year of diagnosis: 1989 to 1993 (n=1077), 1994 to 1998 (n=1633), 1999 to 2002 (n=1622), and 2003 to 2006 (n=1642). Multivariable analysis was performed, with year of diagnosis as a continuous variable. Results: Median follow-up time was 8.6 years. Among patients diagnosed in 1989 to 1993, 1994 to 1998, 1999 to 2002, and 2003 to 2006, the proportions of grade 1 tumors increased (16% vs 29% vs 40% vs 39%, respectively, P<.001). Surgical margin clearance rates increased from 82% to 93% to 95% and 88%, respectively (P<.001). Over time, the proportions of unknown estrogen receptor (ER) status decreased (29% vs 10% vs 1.2% vs 0.5%, respectively, P<.001), whereas ER-positive tumors increased (56% vs 77% vs 86% vs 86%, respectively, P<.001). Hormone therapy use increased (23% vs 23% vs 62% vs 73%, respectively, P<.001), and chemotherapy use increased (2% vs 5% vs 10% vs 13%, respectively, P<.001). The 5-year cumulative incidence rates of LR over the 4 time periods were 2.8% vs 1.7% vs 0.9% vs 0.8%, respectively (Gray's test, P<.001). On competing risk multivariable analysis, year of diagnosis was significantly associated with decreased LR (hazard ratio, 0.92 per year, P=.0003). Relative to grade 1 histology, grades 2, 3, and unknown were associated with increased LR. Hormone therapy use was associated with reduced LR. Conclusion: Significant changes in the multimodality management of stage I breast cancer have occurred over the past 2 decades. More favorable-risk tumors were diagnosed, and margin clearance and systemic therapy use

    Background Aberrant DNA methylation and histone deacetylation participate in cancer development and progression; hence, their reversal by inhibitors of DNA methylation and histone deacetylases (HDACs) is at present undergoing clinical testing in cancer therapy. As epigenetic alterations are common to breast cancer, in this proof-of-concept study demethylating hydralazine, plus the HDAC inhibitor magnesium valproate, were added to neoadjuvant doxorubicin and cyclophosphamide in locally advanced breast cancer to assess their safety and biological efficacy. Methodology This was a single-arm interventional trial on breast cancer patients (ClinicalTrials.gov Identifier: NCT00395655). After signing informed consent, patients were typed for acetylator phenotype and then treated with hydralazine at 182 mg for rapid-, or 83 mg for slow-acetylators, and magnesium valproate at 30 mg/kg, starting from day –7 until chemotherapy ended, the latter consisting of four cycles of doxorubicin 60 mg/m2 and cyclophosphamide 600 mg/m2 every 21 days. Core-needle biopsies were taken from primary breast tumors at diagnosis and at day 8 of treatment with hydralazine and valproate. Main Findings 16 patients were included and received treatment as planned. All were evaluated for clinical response and toxicity and 15 for pathological response. Treatment was well-tolerated. The most common toxicity was drowsiness grades 1–2. Five (31%) patients had clinical CR and eight (50%) PR for an ORR of 81%. No patient progressed. One of 15 operated patients (6.6%) had pathological CR and 70% had residual disease <3 cm. There was a statistically significant decrease in global 5mC content and HDAC activity. Hydralazine and magnesium valproate up- and down-regulated at least 3-fold, 1,091 and 89 genes, respectively. Conclusions Hydralazine and magnesium valproate produce DNA demethylation, HDAC inhibition, and gene reactivation in primary tumors. Doxorubicin and cyclophosphamide treatment is safe, well

    The purpose of this work was to retrospectively evaluate survival and local control rates of triple-negative breast cancer subtypes classified as five marker negative (5NP) and core basal (CB), respectively, after breast-conserving surgery and intraoperative boost radiotherapy with electrons (IOERT) followed by whole breast irradiation. A total of 71 patients with triple-negative breast cancer were enrolled, who were treated with lumpectomy, axillary lymph node dissection, and IOERT with 9.6 Gy (median D{sub max}) followed by normofractionated whole breast irradiation to median total doses of 54 Gy. Chemotherapy was applied in a neoadjuvant (12 %), adjuvant (75 %), or combinational setting (7 %). After a median follow-up of 97 months (range 4-170 months), 5 in-breast recurrences were detected (7.0 %). For all patients, 8-year actuarial rates for local control, metastases-free survival, disease-specific survival, and overall survival amounted to 89, 75, 80, and 69 %, respectively. All local recurrences occurred in grade 3 (G3) tumors irrespective of their specific immunohistochemical phenotype; thus, the local control rate for grades 1/2 (G1/2) was 100 % for both 5NP and CB, while for G3 it was 88 % for 5NP and 90 % for CB (p = 0.65 and 0.82, respectively, n.s.). For disease-specific survival, only the difference of the best-prognosis group 5-NP/G3 vs. the worst-prognosis cohort CB/G1/2 was statistically significant: 90 % vs. 54 % (p = 0.03). Boost-IOERT provides acceptable long-term in-breast control in triple negative breast cancer. The best subgroup in terms of disease-specific survival was represented by 5NP in combination with tumor grading G3. (orig.)

    Introduction: This study was conducted to determine the impact of the brachytherapy parameters on local control in patients treated with irradiation alone for breast cancer. Material and Methods: From 1985 to 1991, 241 patients with T2 (187pts) T3 (54 pts) N0 (196 pts) N1 (45 pts) M0 breast cancer have been treated with the combination of external irradiation and brachytherapy boost without surgery. Doses delivered to the whole breast and the regional nodes were 54 Gy and 50 Gy respectively (1.8 or 2 Gy/fraction, 5 fr/wk). Twenty Gy were then boosted to the primary tumor, according to the tumor shrinkage, by Ir 192 implants. Plastic tubes and rigid needles were used in 85 % and 15 % of the cases respectively. The brachytherapy boost was delivered at 85% of the basal dose rate (Reference dose rate) according to the Paris system. In some instances, dose distribution heterogeneities were observed leading to the choice of another reference isodose. Results: Median follow-up for the entire population was 75 months (9-122). Local control at 6 years follow-up for T2 and T3 was 76% (+/- 6%). Age, SBR grading and steroid receptors were found to be significantly correlated to local control. The role of the brachytherapy boost was analysed. Reference dose rate was not found to have any impact on local control, (≤ 0.6 vs > 0.6 Gy/h). This result was perhaps linked to the particular choice of the reference isodose. To avoid this bias we have evaluated the impact of the Kerma rate (Activity x Time x total length) on local control. Median kerma rate was 8600 μGy h -1 cm -1 m 2 (2200-16600). Local control rate for T2 at 6 years was 77% +/- 8% (Kerma >8600) and 73 %+/- 10% (Kerma ≤ 8600). For T3 local control rate was 82% +/-12% (Kerma >8600) and 37 % +/- 34 % (p<0.0002). Conclusion: This study demonstrated that the impact of brachytherapy on local control was better evaluated by the Kerma rate than by the reference dose rate. Whereas the basal dose rate cannot be changed

    Neuroendocrine breast cancer is thought to account for about 1% of all breast cancers. This rare type of breast malignancy is more common in older women and presents as a low-grade, slow-growing cancer. The most definitive markers that indicate neuroendocrine carcinoma are the presence of chromogranin, synaptophysin or neuron-specific enolase, in at least 50% of malignant tumour cells. The authors present a case report of an 83-year-old woman, admitted to their institution with right breast lump. Physical examination, mammography and ultrasonography showed a 2.4 cm nodule, probably a benign lesion (BI-RADS 3). A fine needle aspiration biopsy was performed and revealed proliferative epithelial papillary lesion. She was submitted to excisional biopsy and histology showed endocrine breast cancer well differentiated (G1). Immunohistochemically, tumour cells were positive for synaptophysin. These breast cancers are characterised for their excellent prognosis and conservative treatment is almost always enough to obtain patient cure.

    2011-01-01

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including trends in incidence, mortality, survival, and screening. Approximately 230,480 new cases of invasive breast cancer and 39,520 breast cancer deaths are expected to occur among US women in 2011. Breast cancer incidence rates were stable among all racial/ethnic groups from 2004 to 2008. Breast cancer death rates have been declining since the early 1990s for all women except American Indians/Alaska Natives, among whom rates have remained stable. Disparities in breast cancer death rates are evident by state, socioeconomic status, and race/ethnicity. While significant declines in mortality rates were observed for 36 states and the District of Columbia over the past 10 years, rates for 14 states remained level. Analyses by county-level poverty rates showed that the decrease in mortality rates began later and was slower among women residing in poor areas. As a result, the highest breast cancer death rates shifted from the affluent areas to the poor areas in the early 1990s. Screening rates continue to be lower in poor women compared with non-poor women, despite much progress in increasing mammography utilization. In 2008, 51.4% of poor women had undergone a screening mammogram in the past 2 years compared with 72.8% of non-poor women. Encouraging patients aged 40 years and older to have annual mammography and a clinical breast examination is the single most important step that clinicians can take to reduce suffering and death from breast cancer. Clinicians should also ensure that patients at high risk of breast cancer are identified and offered appropriate screening and follow-up. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

    Full Text Available BACKGROUND Worldwide, breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting for treatment has two common problems in treatment. Achieving local control and prolonging survival by preventing or delaying distant metastasis. Today, treatment of LABC requires a combination of systemic and local/regional therapies. The aim of the study is to study the clinicopathological presentation, age distribution and various modes of management of locally advanced breast carcinoma. Worldwide breast cancer is the most frequent cancer in women and represents the second leading cause of cancer death among women. Locally advanced breast cancer constitutes more than 50-70% of the patients presenting treatment. MATERIALS AND METHODS The present study includes 50 patients who attended Department of General Surgery for a period of three years. RESULTS The patients were regularly followed up and at the end of the study 35 (70% of the patients were doing well. 4(8% of the patients developed distant metastasis and 3 (6% of the patients developing local recurrence. 8 (16% of the patients were lost follow up. CONCLUSION About half of the cases presenting with breast cancer are in locally advanced stages. Multimodality therapy is the effective treatment of locally advanced carcinoma of breast. Breast cancer management is a challenge and improvement in therapies are needed for disease-free interval and overall survival period.

  3. Risk of myeloid neoplasms after radiotherapy among older women with localized breast cancer: A population-based study.

    Directory of Open Access Journals (Sweden)

    Full Text Available There are inconsistent and limited data regarding the risk of myeloid neoplasms (MN among breast cancer survivors who received radiotherapy (RT in the absence of chemotherapy. Concern about subsequent MN might influence the decision to use adjuvant RT for women with localized disease. As patients with therapy-related MN have generally poor outcomes, the presumption of subsequent MN being therapy-related could affect treatment recommendations.We used the Surveillance, Epidemiology, and End Results (SEER-Medicare linked database to study older women with in-situ or stage 1-3 breast cancer diagnosed 2001-2009 who received surgery. Chemotherapy and RT were ascertained using Medicare claims, and new MN diagnoses were captured using both SEER registry and Medicare claims. We excluded women who received chemotherapy for initial treatment, and censored at receipt of subsequent chemotherapy. Competing-risk survival analysis was used to assess the association between RT and risk of subsequent MN adjusting for relevant characteristics.Median follow-up for 60,426 eligible patients was 68 months (interquartile range, 46 to 92 months, with 47.6% receiving RT. In total, 316 patients (0.52% were diagnosed with MN; the cumulative incidence per 10,000 person-years was 10.6 vs 9.0 among RT-treated vs non-RT-treated women, respectively (p = .004; the increased risk of subsequent MN persisted in the adjusted analysis (hazard ratio = 1.36, 95% confidence interval: 1.03-1.80. The results were consistent in multiple sensitivity analyses.Our data suggest that RT is associated with a significant risk of subsequent MN among older breast cancer survivors, though the absolute risk increase is very small. These findings suggest the benefits of RT outweigh the risks of development of subsequent MN.

    In a study of the X-ray images of the thorax of 469 women, who had undergone operative treatment and postoperative radiation therapy of breast cancer, the authors detected in 11 patients the localized ''pseudofracture'' type of pathologic reconstruction of the costal bone structure. In 10 patients the changes were localized in the anterior part of the second ribs, and in one - in the anterior part of the 5th rib. They were detected on X-ray examination 11 to 15 months after the onset of radiation treatment and clinically ran a symptomless course. Roentgenographically the changes consisted in: transverse rarefication strips with perifocal streaky densities; transverse rarefication strips and fine pseudocystic reconstruction of the adjacent bone structure; transverse rarefication strips with a gradual reconstruction of the adjacent lateral segment of the rib, till its complete roentgenologic disappearance. There was no periosteal reaction. The second and the third type of X-ray changes resembled metastasis. (author)

    Justicia gendarussa methanolic leaf extracts from five different locations in the Southern region of Peninsular Malaysia and two flavonoids, kaempferol and naringenin, were tested for cytotoxic activity. Kaempferol and naringenin were two flavonoids detected in leaf extracts using gas chromatography-flame ionization detection (GC-FID). The results indicated that highest concentrations of kaempferol and naringenin were detected in leaves extracted from Mersing with 1591.80 mg/kg and 444.35 mg/kg, respectively. Positive correlations were observed between kaempferol and naringenin concentrations in all leaf extracts analysed with the Pearson method. The effects of kaempferol and naringenin from leaf extracts were examined on breast cancer cell lines (MDA-MB-231 and MDA-MB-468) using MTT assay. Leaf extract from Mersing showed high cytotoxicity against MDA-MB-468 and MDA-MB-231 with IC50 values of 23 μg/mL and 40 μg/mL, respectively, compared to other leaf extracts. Kaempferol possessed high cytotoxicity against MDA-MB-468 and MDA-MB-231 with IC50 values of 23 μg/mL and 34 μg/mL, respectively. These findings suggest that the presence of kaempferol in Mersing leaf extract contributed to high cytotoxicity of both MDA-MB-231 and MDA-MB-468 cancer cell lines. PMID:25574182

    Breast cancer is the most common malignant neoplasm in women, and 6% will develop it during their normal life expectancy. There is a group who have a high risk of developing breast cancer. The recent improvement in cure rates seems to be jue chiefly to earlier diagnosis rather than to improved methods of therapy. The physician, by careful periodic breast examinations and by the judicious use of diagnostic aids such as mammography and thermography, especially in the high risk group, has a golden opportunity to pick up cancer in a localized stage where the prognosis for cure with appropriate therapy is excellent. A tentative diagnosis of breast cancer (Table XI) can be made with a fair degree of accuracy by taking a careful history, utilizing and combining available statistics about the frequency, median age, characteristic symptom complexes of the common breast lesions and factors related to a high mammary carcinoma risk, and by a systematic and thorough breast examination supplemented with diagnostic aids when appropriate. However, biopsy and histologic examination is mandatory in all patients with a) true, three dimentional, dominant lumps even if diagnostic aids are negative except for cysts which can be safely aspirated under controlled conditions; b) suspicious lesions found by diagnostic aids even though there are no clinical findings; c) serous, serosanguineous, bloody, or watery nipple discharge; and d) other signs of cancer, i.e. eczema of the nipple, axillary adenopathy, etc., in order to determine with absolute accuracy whether the lesion is benign or malignant.

    Full Text Available Breast cancer remains a major public health problem, being the second cause of cancer death in women. There is a marked tendency to restrict the extension of surgical gesture, which directly leads to two different attitudes: radical surgery and conservative surgery, to which, at least in our country, there are still some delays. Prospective and retrospective studies have shown that, in 20 years, conservative and radical therapy had about the same rate of survival and disease-free interval, at least for stage I and II breast cancer, the only real counterargument against conservative surgery being that, in principle, the higher rate of recurrence local constraint can be solved by postoperative radiotherapy. Finally, the survival rate is the main parameter of evaluation, assessing the effectiveness of the treatment in breast cancer, and in all its other forms.

    This study aims to develop and test a new imaging marker-based short-term breast cancer risk prediction model. An age-matched dataset of 566 screening mammography cases was used. All ‘prior’ images acquired in the two screening series were negative, while in the ‘current’ screening images, 283 cases were positive for cancer and 283 cases remained negative. For each case, two bilateral cranio-caudal view mammograms acquired from the ‘prior’ negative screenings were selected and processed by a computer-aided image processing scheme, which segmented the entire breast area into nine strip-based local regions, extracted the element regions using difference of Gaussian filters, and computed both global- and local-based bilateral asymmetrical image features. An initial feature pool included 190 features related to the spatial distribution and structural similarity of grayscale values, as well as of the magnitude and phase responses of multidirectional Gabor filters. Next, a short-term breast cancer risk prediction model based on a generalized linear model was built using an embedded stepwise regression analysis method to select features and a leave-one-case-out cross-validation method to predict the likelihood of each woman having image-detectable cancer in the next sequential mammography screening. The area under the receiver operating characteristic curve (AUC) values significantly increased from 0.5863  ±  0.0237 to 0.6870  ±  0.0220 when the model trained by the image features extracted from the global regions and by the features extracted from both the global and the matched local regions (p  =  0.0001). The odds ratio values monotonically increased from 1.00-8.11 with a significantly increasing trend in slope (p  =  0.0028) as the model-generated risk score increased. In addition, the AUC values were 0.6555  ±  0.0437, 0.6958  ±  0.0290, and 0.7054  ±  0.0529 for the three age groups of 37

    Full Text Available Cancer metastasis, resistance to therapies and disease recurrence are significant hurdles to successful treatment of breast cancer. Identifying mechanisms by which cancer spreads, survives treatment regimes and regenerates more aggressive tumours are critical to improving patient survival. Substantial evidence gathered over the last 10 years suggests that breast cancer progression and recurrence is supported by cancer stem cells (CSCs. Understanding how CSCs form and how they contribute to the pathology of breast cancer will greatly aid the pursuit of novel therapies targeted at eliminating these cells. This review will summarise what is currently known about the origins of breast CSCs, their role in disease progression and ways in which they may be targeted therapeutically.

    Purpose and approach: to report a case of morphea (localized scleroderma) in a patient following breast cancer therapy and to summarize the current literature. Results and conclusion: the occurrence of morphea is an unexpected late effect (approximately 1 year after the end of radiation therapy) which occurs frequently in the irradiated breast in women with breast-conserving therapy. The pathogenesis is unclear. The main differential diagnoses are recurrence of carcinoma and a radiogenic subcutaneous fibrosis (in most cases, the final diagnosis can only be made by means of a biopsy). Diagnosis and therapy must be performed in cooperation between dermatologist and radiooncologist. (orig.)

    Microcalcifications can be the early and only presenting sign of breast cancer. One shared characteristic of breast cancer is the appearance of mammographic mammary microcalcifications that can routinely be used to detect breast cancer in its initial stages, which is of key importance due to the possibility that early detection allows the application of more conservative therapies for a better patient outcome. The mechanism by which mammary microcalcifications are formed is still largely unknown but breast cancers presenting microcalcifications are more often associated with a poorer prognosis. We combined Capillary Electrochromatography, histology, and gene expression (qRT-PCR) to analyze patient-matched normal breast tissue vs. breast tumor. Potential carcinogenicity of oxalate was tested by its inoculation into mice. All data were subjected to statistical analysis. To study the biological significance of oxalates within the breast tumor microenvironment, we measured oxalate concentration in both human breast tumor tissues and adjoining non-pathological breast tissues. We found that all tested breast tumor tissues contain a higher concentration of oxalates than their counterpart non-pathological breast tissue. Moreover, it was established that oxalate induces proliferation of breast cells and stimulates the expression of a pro-tumorigenic gene c-fos. Furthermore, oxalate generates highly malignant and undifferentiated tumors when it was injected into the mammary fatpad in female mice, but not when injected into their back, indicating that oxalate does not induce cancer formation in all types of tissues. Moreover, neither human kidney-epithelial cells nor mouse fibroblast cells proliferate when are treated with oxalate. We found that the chronic exposure of breast epithelial cells to oxalate promotes the transformation of breast cells from normal to tumor cells, inducing the expression of a proto-oncogen as c-fos and proliferation in breast cancer cells

  3. PET imaging in breast cancer

    The basis of tumour imaging with PET is a specific uptake mechanism of positron emitting radiopharmaceuticals. Among the potential tracers for breast cancer (fluorodeoxyglucose, methionine, tyrosine, fluoro-estradiol, nor-progesterone), 2-deoxy-2-fluoro-D-glucose labelled with fluorine (FDG) is the most widely used radiopharmaceutical because breast cancer is particularly avid of FDG and 18 F has the advantages of the a relatively long physical half-life. Mammography is the first choice examination in studying breast masses, due to its very good performances, an excellent compliance and the best value regarding the cost/effectiveness aspects. The FDG uptake in tissue correlates with the histological grade and potential aggressiveness of breast cancer and this may have prognostic consequences. Besides the evaluation of breast lesions, FDG-PET shows a great efficacy in staging lymph node involvement prior surgery and this could have a great value in loco-regional staging. Whole body PET provides also information with regard to metastasis localizations both in soft tissue and bone, and plays an important clinical role mainly in detecting recurrent metastatic disease. In fact for its metabolic characteristics PET visualizes regions of enhanced metabolic activity and can complete other imaging modalities based on structural anatomic changes. Even though CT and MRI show superior resolution characteristics, it has been demonstrated that PET provides more accurate information in discriminating between viable tumour, fibrotic scar or necrosis. These statements are coming from the examination of more than 2000 breast cancer detection

    It has long been proposed that the gut microbiome contributes to breast carcinogenesis by modifying systemic estrogen levels. This is often cited as a possible mechanism linking breast cancer and high-fat, low-fiber diets as well as antibiotic exposure, associations previously identified in population-based studies. More recently, a distinct microbiome has been identified within breast milk and tissue, but few studies have characterized differences in the breast tissue microbiota of patients with and without cancer, and none have investigated distant body-site microbiomes outside of the gut. We hypothesize that cancerous breast tissue is associated with a microbiomic profile distinct from that of benign breast tissue, and that microbiomes of more distant sites, the oral cavity and urinary tract, will reflect dysbiosis as well. Fifty-seven women with invasive breast cancer undergoing mastectomy and 21 healthy women undergoing cosmetic breast surgery were enrolled. The bacterial 16S rRNA gene was amplified from urine, oral rinse and surgically collected breast tissue, sequenced, and processed through a QIIME-based bioinformatics pipeline. Cancer patient breast tissue microbiomes clustered significantly differently from non-cancer patients ( p =0.03), largely driven by decreased relative abundance of Methylobacterium in cancer patients (median 0.10 vs. 0.24, p =0.03). There were no significant differences in oral rinse samples. Differences in urinary microbiomes were largely explained by menopausal status, with peri/postmenopausal women showing decreased levels of Lactobacillus . Independent of menopausal status, however, cancer patients had increased levels of gram-positive organisms including Corynebacterium ( p <0.01), Staphylococcus ( p =0.02) , Actinomyces ( p <0.01), and Propionibacteriaceae ( p <0.01). Our observations suggest that the local breast microbiota differ in patients with and without breast cancer. Cancer patient urinary microbiomes were

    Breast cancer is the most frequent cancer of women in western countries. There are one million new cases per year in the world which represents 22% of all female cancers, and more than 370.000 deaths due to breast cancer per year (14% of cancer mortality). More than half of breast cancers are associated with axillary nodal involvement. Post-operative radiation therapy (XRT) is a crucial part of locoregional treatment in axillary nodal involvement breast cancer owing to a 15-years risk reduction of locoregional recurrence of 70% and to a 5.4% risk reduction of specific mortality. In 3D-conformal irradiation in such breast cancers, target volumes are chest wall when mastectomy was performed or breast and boost of tumor bed in case of breast conservative surgery, and supra-clavicular and/or axillary and/or internal mammary node areas. The main organs at risk are ipsilateral lung, heart and brachial plexus. The aim of this article is to describe epidemiologic, radio anatomic and prognostic features of axillary nodal involvement breast cancer and to propose guidelines for 3D-conformal treatment planning in locally advanced breast cancers. This review is illustrated by a case report. (authors)

    A multimodal treatment combining intra-arterial chemotherapy and intensive loco-regional radiotherapy was administered to 55 patients with locally advanced breast cancer. Adjuvant polychemotherapy followed, and eventually endocrino-therapy. Combined intra-arterial chemotherapy and intensive radiotherapy gave excellent results in both primary and lymph node lesions, with 90.9% and 92.2% complete/partial response rates. Three-year and 5-year actuarial survival rates were 69% and 59%, respectively. Patients showing better local responses to combined intra-arterial chemotherapy and intensive radiotherapy had longer survival and less frequent local recurrences. Combined intra-arterial chemotherapy and intensive loco-regional radiotherapy seems to be an effective modality for the treatment of locally advanced breast cancer.

    BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted...... a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models. RESULTS: Compared...... with women with non-preeclamptic pregnancies only, women with one or more preeclamptic pregnancies were 19% significantly less likely to develop breast cancer (IRR = 0.81 [95% CI 0.72-0.93]). We found some indication of greater risk reduction in women with term births, one or more previous births...

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

  19. On the Use of Local Search in the Evolution of Neural Networks for the Diagnosis of Breast Cancer

    2015-07-01

    Full Text Available With the advancement in the field of Artificial Intelligence, there have been considerable efforts to develop technologies for pattern recognition related to medical diagnosis. Artificial Neural Networks (ANNs, a significant piece of Artificial Intelligence forms the base for most of the marvels in the former field. However, ANNs face the problem of premature convergence at a local minimum and inability to set hyper-parameters (like the number of neurons, learning rate, etc. while using Back Propagation Algorithm (BPA. In this paper, we have used the Genetic Algorithm (GA for the evolution of the ANN, which overcomes the limitations of the BPA. Since GA alone cannot fit for a high-dimensional, complex and multi-modal optimization landscape of the ANN, BPA is used as a local search algorithm to aid the evolution. The contributions of GA and BPA in the resultant approach are adjudged to determine the magnitude of local search necessary for optimization, striking a clear balance between exploration and exploitation in the evolution. The algorithm was applied to deal with the problem of Breast Cancer diagnosis. Results showed that under optimal settings, hybrid algorithm performs better than BPA or GA alone.

  20. Accessory breast tissue in axilla masquerading as breast cancer recurrence

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

    DNA-damage assays, quantifying the initial number of DNA double-strand breaks induced by radiation, have been proposed as a predictive test for radiation-induced toxicity. Determination of radiation-induced apoptosis in peripheral blood lymphocytes by flow cytometry analysis has also been proposed as an approach for predicting normal tissue responses following radiotherapy. The aim of the present study was to explore the association between initial DNA damage, estimated by the number of double-strand breaks induced by a given radiation dose, and the radio-induced apoptosis rates observed. Peripheral blood lymphocytes were taken from 26 consecutive patients with locally advanced breast carcinoma. Radiosensitivity of lymphocytes was quantified as the initial number of DNA double-strand breaks induced per Gy and per DNA unit (200 Mbp). Radio-induced apoptosis at 1, 2 and 8 Gy was measured by flow cytometry using annexin V/propidium iodide. Radiation-induced apoptosis increased in order to radiation dose and data fitted to a semi logarithmic mathematical model. A positive correlation was found among radio-induced apoptosis values at different radiation doses: 1, 2 and 8 Gy (p < 0.0001 in all cases). Mean DSB/Gy/DNA unit obtained was 1.70 ± 0.83 (range 0.63-4.08; median, 1.46). A statistically significant inverse correlation was found between initial damage to DNA and radio-induced apoptosis at 1 Gy (p = 0.034). A trend toward 2 Gy (p = 0.057) and 8 Gy (p = 0.067) was observed after 24 hours of incubation. An inverse association was observed for the first time between these variables, both considered as predictive factors to radiation toxicity

    Breast cancer patients show a wide variation in normal tissue reactions after radiotherapy. The individual sensitivity to x-rays limits the efficiency of the therapy. Prediction of individual sensitivity to radiotherapy could help to select the radiation protocol and to improve treatment results. The aim of this study was to assess the relationship between gene expression profiles of ex vivo un-irradiated and irradiated lymphocytes and the development of toxicity due to high-dose hyperfractionated radiotherapy in patients with locally advanced breast cancer. Raw data from microarray experiments were uploaded to the Gene Expression Omnibus Database http://www.ncbi.nlm.nih.gov/geo/ (GEO accession GSE15341). We obtained a small group of 81 genes significantly regulated by radiotherapy, lumped in 50 relevant pathways. Using ANOVA and t-test statistical tools we found 20 and 26 constitutive genes (0 Gy) that segregate patients with and without acute and late toxicity, respectively. Non-supervised hierarchical clustering was used for the visualization of results. Six and 9 pathways were significantly regulated respectively. Concerning to irradiated lymphocytes (2 Gy), we founded 29 genes that separate patients with acute toxicity and without it. Those genes were gathered in 4 significant pathways. We could not identify a set of genes that segregates patients with and without late toxicity. In conclusion, we have found an association between the constitutive gene expression profile of peripheral blood lymphocytes and the development of acute and late toxicity in consecutive, unselected patients. These observations suggest the possibility of predicting normal tissue response to irradiation in high-dose non-conventional radiation therapy regimens. Prospective studies with higher number of patients are needed to validate these preliminary results

    To prospectively evaluate the effect of adding whole-body (18)F-2-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET) to conventional screening for distant metastases in patients with locally advanced breast cancer (LABC). All women with LABC referred for participation in the LABC Spinoza trial were considered eligible for this study. Patients were included if chest x-ray, bone scan, liver ultrasound, or computed tomography scan performed by the referring physician failed to reveal distant metastases. They underwent whole-body FDG PET scanning before therapy. Patients with subsequently proven distant metastases were switched to alternative forms of chemotherapy, hormonal therapy, or both. Among the 48 patients evaluated with PET, 14 had abnormal FDG uptake, and metastases were suspected in 12. After simple clinical evaluation (plain x-ray, history), 10 sites that were suggestive of abnormality remained. Further work-up revealed that four sites were metastases. Proven false positivity occurred in one patient with sarcoidosis. In the other five patients, the reason for abnormal FDG uptake (liver, lung, bone) remained unclear, and patients were treated as planned. Eleven months later, distant metastases were found in one patient at sites unrelated to the previous FDG uptake. The addition of FDG PET to the standard work-up of patients with LABC may lead to the detection of unexpected distant metastases. This may contribute to a more realistic stratification between patients with true stage III breast cancer and those who are in fact suffering from stage IV disease. Abnormal PET findings should be confirmed to prevent patients from being denied appropriate treatment.

    Cancer immunoediting is the process by which the immune system protects the host from tumor development and guides the somatic evolution of tumors by eliminating highly immunogenic tumor cells. A fundamental dogma of tumor immunology and of cancer immunosurveillance in particular is that cancer cells express antigens that differentiate them from their nontransformed counterparts. Molecular studies clearly show that these antigens were often products of mutated cellular genes, aberrantly expressed normal genes, or genes encoding viral proteins. There is a strict correlation between genetic instability and the immune landscape of a breast cancer. Mutational heterogeneity in breast cancer is associated with new cancer-associated genes and new cancer antigens. Frequencies of somatic mutations or mutational burden can be related to the immunogenicity of breast cancer. We believe that molecular subtypes of breast cancer that are triple negative, luminal B-like or HER2-positive have a high mutational burden and can be considered immunogenic. The increasing knowledge of the immune system's capacity to not only recognize and destroy cancer, but also to shape cancer immunogenicity will develop more informed attempts to control cancer via immunological approaches. To be effective in breast cancer, immunotherapies will have to increase the quality or quantity of immune effector cells, reveal additional protective tumor antigens, and/or eliminate cancer-induced immunosuppressive mechanisms. Multiple immunotherapy approaches are under investigation in patients with breast cancer. These include vaccine approaches to elicit strong specific immune responses to tumor antigens such as WT-1, HER2 and NY-ESO-1, approaches involving adoptive transfer of in vitro-expanded, naturally arising or genetically engineered tumor-specific lymphocytes, therapeutic administration of monoclonal antibodies to target and eliminate tumor cells, and approaches that inhibit or destroy the molecular or

    Background and purpose: Ongoing concern remains regarding cardiac injury with hypofractionated whole breast/chest-wall radiotherapy (HF-WBI) compared to conventional radiotherapy (CF-WBI) in left-sided breast cancer patients. The purpose was to determine if cardiac mortality increases with HF-WBI relative to CF-WBI. Materials and methods: Between 1990 and 1998, 5334 women with early-stage breast cancer received post-operative radiotherapy to the breast/chest wall alone. A population-based database recorded baseline patient, tumor and treatment factors. Baseline cardiovascular risk factors were identified from hospital administrative records. A propensity-score model balanced risk factors between radiotherapy groups. Cause of death was coded as breast cancer, cardiac or other cause. Cumulative mortality from each cause after radiotherapy was estimated using a competing risk approach. Results: For left-sided cases, median follow-up was 14.2 years. 485 women received CF-WBI, 2221 women received HF-WBI. There was no difference in 15-year mortality from cardiac causes: 4.8% with HF-WBI and 4.2% with CF-WBI (p = 0.74), even after propensity-score adjustment (p = 0.45). There was no difference in breast cancer mortality or other cause mortality. For right-sided cases, there was no difference in mortality for the three causes of death. Conclusions: At 15-years follow-up, cardiac mortality is not statistically different among left-sided breast cancer patients treated with HF-WBI or CF-WBI

    Purpose: Previous studies have demonstrated how imaging of the breast with patients lying prone using a supportive positioning device markedly facilitates longitudinal and/or multimodal image registration. In this contribution, the authors’ primary objective was to determine if there are differences in the standardized uptake value (SUV) derived from [ 18 F]fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) in breast tumors imaged in the standard supine position and in the prone position using a specialized positioning device. Methods: A custom positioning device was constructed to allow for breast scanning in the prone position. Rigid and nonrigid phantom studies evaluated differences in prone and supine PET. Clinical studies comprised 18F-FDG-PET of 34 patients with locally advanced breast cancer imaged in the prone position (with the custom support) followed by imaging in the supine position (without the support). Mean and maximum values (SUV peak and SUV max , respectively) were obtained from tumor regions-of-interest for both positions. Prone and supine SUV were linearly corrected to account for the differences in 18F-FDG uptake time. Correlation, Bland–Altman, and nonparametric analyses were performed on uptake time-corrected and uncorrected data. Results: SUV from the rigid PET breast phantom imaged in the prone position with the support device was 1.9% lower than without the support device. In the nonrigid PET breast phantom, prone SUV with the support device was 5.0% lower than supine SUV without the support device. In patients, the median (range) difference in uptake time between prone and supine scans was 16.4 min (13.4–30.9 min), which was significantly—but not completely—reduced by the linear correction method. SUV peak and SUV max from prone versus supine scans were highly correlated, with concordance correlation coefficients of 0.91 and 0.90, respectively. Prone SUV peak and SUV max were significantly lower than supine in both

    Oral contraceptive use is weakly associated with breast cancer risk in the general population, but the association among women with a familial predisposition to breast cancer is less clear. Recent studies indicating that oral contraception may increase the risk of breast cancer more in subjects who are BRCA 1 or BRCA 2 mutation carriers. Features of hormonal contraceptive use, such as duration of use, age at first use, and the dose and type of hormone within the contraceptives, have little effect on breast cancer risk. Women who begin use before age 20 have higher relative risks of having breast cancer diagnosed while they are using combined oral contraceptives and in the 5 years after stopping than do women who begin use at older ages. Given that on influence of oral contraceptives on the breast has been hypothesized to be greatest before the cellular differentiation that occurs with a first pregnancy. A significant trend of increasing risk with first use before age 20 years was observed. Among women diagnosed at ages 30 to 34 years the relative risk associated with recent oral contraceptive use was 1.54 if use began before age 20 years and 1.13 it use began at older ages.

    Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers. This is potentially good news as effective vaccines are already available to prevent infections from carcinogenic strains of human papilloma virus, which causes cancer of the uterine cervix.

    Background In the past decades the incidence of pregnancy-associated breast cancer (PABC) increased. Possible explanations are the trend to postpone childbearing and the general increase in the incidence of breast cancer. Materials and methods A sytematic review of the literature was performed with the aim to report on incidence, diagnosis, treatment and prognosis of breast cancer during pregnancy. We also cover the issue of pregnancy following a diagnosis of breast cancer including fertility preservation and prognosis. Results Ultrasound is the imaging method of choice in pregnancy, but mammography can also be performed as the fetal irradiation dose is low. To avoid a delay in diagnosis every sonographic mass in pregnant women which does not clearly correspond to a cyst needs further investigation by biopsy. Treatment should follow as close as possible the guidelines for non-pregnant patients. Administration of chemotherapy is possible after the first trimester. There is a large body of evidence for the use of anthracyclines. In contrast radiotherapy, trastuzumab and antihormonal treatment by tamoxifen are contraindicated during pregnancy. Pregnancy does not seem to influence prognosis. Most adverse obstetric outcomes are related to preterm delivery, which should therefore, whenever possible, be avoided. Young patients with breast cancer and incomplete family planning should be referred for counseling about fertility preservation options before the initiation of adjuvant treatment. A pregnancy following breast cancer does not have a negative impact on prognosis. Conclusion Multidisciplinary management of women with breast cancer in pregnancy is mandatory and data should be collected to allow further improvement in management.

    The BioScan System was developed by OmniCorder Technologies, Inc. at the Jet Propulsion Laboratory. The system is able to locate cancerous lesions by detecting the cancer's ability to recruit a new blood supply. A digital sensor detects infrared energy emitted from the body and identifies the minute differences accompanying the blood flow changes associated with cancerous cells. It also has potential use as a monitoring device during cancer treatment. This technology will reduce the time taken to detect cancerous cells and allow for earlier intervention, therefore increasing the overall survival rates of breast cancer patients.

    Purpose: This article describes our technique of localization and implantation of the lumpectomy site of patients with T1 and T2 breast cancer. Our method was developed as part of our Phase I/II pilot study of high dose rate (HDR) brachytherapy alone after conservative surgery for early breast cancer. Methods and Materials: In March 1992, we started a pilot study of HDR brachytherapy to the lumpectomy site as the sole radiotherapy after conservative surgery for clinical T1 or T2 invasive breast cancer. Initially, the protocol required intraoperative placement of the interstitial needles at the time of definitive surgery to the breast. The protocol was then generalized to allow the implantation of the lumpectomy site after definitive surgery to the breast, either at the time of subsequent axillary nodal dissection or postoperatively. To date, five patients have been implanted intraoperatively at the time of definitive breast surgery. Twelve patients were implanted after definitive breast surgery, with 7 patients being done at the time of axillary nodal dissection and 5 patients postoperatively. We devised a method of accurately localizing and implanting the lumpectomy site after definitive breast surgery. The method relies on the previous placement of surgical clips by the referring surgeon to mark the lumpectomy site. For each patient, a breast mold is made with radio-opaque angiocatheters taped onto the mold in the supero-inferior direction. A planning CT scan is then obtained through the lumpectomy site. The volume of the lumpectomy site, the number of implant planes necessary, and the orientation of the implants are then determined from the CT scan. The angiocatheters provide a reference grid on the CT films to locate the entry and exit points of the interstitial needles on the plastic mold. The entry and exit points for reference needles are then transferred onto the patient's skin enabling implantation of the lumpectomy site. Needle positions with respect to

    Bisphosphonates are osteoclast inhibitors, currently being used in oncology to prevent or delay bone morbidity in cancer. Oral and intravenous formulations of bisphosphonates have been found to be efficacious in preventing skeletal-related events such as bone pain, pathologic fractures, spinal cord compression and hypercalcemia of malignancy, in patients with bone metastatic breast cancer. Bisphosphonates are also used to prevent bone loss associated with anti-estrogen therapy using aromatase inhibitors. In addition to its role in preventing bone resorption, several pre-clinical studies have noted an anti-tumor role as well. Recent research effort has particularly focused on investigating an adjuvant role for bisphosphonates in early breast cancer. Recently, few randomized trials have found a beneficial effect for adjuvant use of the aminobisphosphonate, zoledronate, in older patients who are post-menopausal. This review article will summarize the various clinical studies investigating the role of bisphosphonates in breast cancer. © 2014 UICC.

    Full Text Available Trials with tamoxifen have clearly shown that the risk of developing oestrogen receptor positive breast cancer can be reduced by at least 50% with prophylactic agents. The current challenge is to find new agents which achieve this or better efficacy, but with fewer side effects. Recent results indicate that the SERM raloxifene has similar efficacy to tamoxifen, but leads to fewer endometrial cancers, gynecological symptoms, and thromboembolic events. Results for contralateral tumors in adjuvant trials suggest that aromatase inhibitors may be able to prevent up to 70%–80% of ER-positive breast cancers, and this is currently being investigated in two large prevention trials, one using anastrozole (IBIS-II and the other exemestane (MAP.3. New agents are needed for receptor negative breast cancer and several possibilities are currently under investigation.

    Pathologic complete response (pCR) after preoperative systemic chemotherapy (PSCh) is associated with better outcome in locally advanced breast cancer (LABC). PSCh included: doxorubicin (A) 50 mg/m(2) i.v. on day 1; docetaxel (T) 30 mg/m(2) i.v. on days 1, 8 and 15; and capecitabine (X) 1,500 mg/m(2)/day p.o. on days 1-14, in a 4-week course repeated for up to four cycles (ATX), followed by surgery. The primary end point of this study was to evaluate the pCR rate. Secondary endpoints included clinical response rate, disease-free survival (DFS), overall survival (OS), and the toxicity profile. A total of 60 patients were included in the analysis. Median age was 49 years, and 63.3% of patients were hormone receptor positive. The median number of cycles of PSCh was four (95% CI: 3-4). Five patients (8.3%) achieved pCR in both breast and nodes, and 16.7% reached pCR only in nodes. The clinical response rate was 77% (27% complete response), but only 18% of the patients underwent conservative surgery. With a median follow-up of 20 months, 3-year DFS and OS were 76 and 90%, respectively. Grade III/IV toxicity included neutropenia (74%), febrile neutropenia (9%), mucositis (12%), and diarrhea (12%). ATX every 28 days for four cycles is associated with a modest activity (low pCR rate) in the neoadjuvant setting of LABC.

    In this article, the use of different types of thermotherapies to treat breast cancer is reviewed. While hyperthermia is most commonly used as an adjuvant in combination with radiotherapy, chemotherapy, targeted therapy or cryotherapy to enhance the therapeutic effect of these therapies, thermoablation is usually carried out alone to eradicate small breast tumors. A recently developed thermotherapy, called magnetic hyperthermia, which involves localized heating of nanoparticles under the application of an alternating magnetic field, is also presented. The advantages and drawbacks of these different thermotherapies are highlighted. PMID:24959300

    Breast cancer is one of the most common cancers diagnosed during pregnancy and its frequency is increasing as more women postpone their pregnancies to their thirties and forties. Breast cancer diagnosis during pregnancy and lactation is difficult and complex both for the patient and doctors. Delay in diagnosis is frequent and treatment modalities are difficult to accept for the pregnant women. The common treatment approach is surgery after diagnosis, chemotherapy after the first trimester and radiotherapy after delivery. Even though early stage breast cancers have similar prognosis, advanced stage breast cancers diagnosed during pregnancy and lactation have poorer prognosis than similar stage breast cancers diagnosed in non-pregnant women. Women who desire to become pregnant after treatment of breast cancer will have many conflicts. Although the most common concern is recurrence of breast cancer due to pregnancy, the studies conducted showed that pregnancy has no negative effect on breast cancer prognosis. In this review we search for the frequency of breast cancer during pregnancy, the histopathological findings, risk factor, diagnostic and treatment modalities. We reviewed the literature for evidence based findings to help consult the patients on the outcome of breast cancer diagnosed during pregnancy and lactation, and also inform the patients who desire to become pregnant after breast cancer according to current evidences.

    Purpose: The significance of lobular carcinoma in situ (LCIS) associated with invasive breast cancer in patients undergoing breast-conserving therapy (BCT) remains controversial. We examined the impact of the presence and extent of LCIS associated with invasive breast cancer on clinical outcome in BCT patients. Methods and Materials: From 1980 to 1996, 607 cases of invasive breast cancer were treated with BCT. All slides were reviewed by a single pathologist. Positive margin was defined as presence of invasive carcinoma/ductal carcinoma in situ at the inked margin. Multiple clinical, pathologic, and treatment-related variables were analyzed for their association with ipsilateral breast tumor recurrence (IBTR) and true recurrence/marginal miss (TR/MM). Median follow-up was 8.7 years. Results: Fifty-six patients (9%) had LCIS in association with invasive cancer. On univariate analysis, positive final margin, positive/no reexcision, smaller maximum specimen dimension, and the presence of LCIS predicted for IBTR. The 10-year IBTR rate was 14% for cases with LCIS vs. 7% without LCIS (p = 0.04). On multivariate analysis, positive margin (p < 0.01), positive/no reexcision (p = 0.04), and presence of LCIS (p = 0.02) remained independently associated with IBTR; positive margin (p < 0.01) and LCIS (p = 0.04) were also associated with TR/MM failure. When examining only cases with negative final margins, the presence of LCIS remained associated with higher IBTR and TR/MM rates (p < 0.01). Conclusion: The presence of LCIS was independently associated with higher rate of IBTR and TR/MM after BCT for invasive breast cancer. LCIS may have significant premalignant potential and progress to an invasive IBTR at the site of index lesion. The adequacy of excision of LCIS associated with invasive carcinoma should be considered in patients undergoing BCT

    Purpose. - Currently, radical mastectomy represents the gold standard for ipsilateral breast cancer recurrence. However, we already showed that a second conservative treatment was feasible combining lumpectomy plus low-dose rate interstitial brachytherapy. In this study, we reported the preliminary results of a second conservative treatment using a high-dose rate brachytherapy. Patients and methods. - From June 2005 to July 2009, 42 patients presenting with an ipsilateral breast cancer recurrence underwent a second conservative treatment. Plastic tubes were implanted intraoperatively at the time of the lumpectomy. After a post-implant CT scan, a total dose of 34 Gy in 10 fractions over 5 consecutive days was delivered through an ambulatory procedure. The toxicity evaluation used the Common Terminology Criteria for Adverse Events v3.0. Results. - The median follow-up was 21 months (6-50 months), median age at the time of the local recurrence was 65 years (30-85 years). The median delay between the primary and the recurrence was 11 years (1-35 years). The location of the recurrence was in the tumor bed for 22 patients (52.4%), in the same quadrant for 14 patients (33.3%) and unknown for six patients (14.3%). The median tumor size of the recurrence was 12 mm (2-30 mm). The median number of plastic tubes and plans were nine (5-12) and two (1-3) respectively. The median CTV was 68 cm{sup 3} (31.2-146 cm{sup 3}). The rate of second local control was 97%. Twenty-two patients (60%) experienced complications. The most frequent side effect consisted in cutaneous and sub-cutaneous fibrosis (72% of all the observed complications). Conclusion. - A second conservative treatment for ipsilateral breast cancer recurrence using high-dose rate brachytherapy appears feasible leading to encouraging results in terms of second local control with an acceptable toxicity. Considering that a non-inferiority randomized trial comparing mastectomy versus second conservative treatment could be

    Breast cancer is the field of medicine with the greatest presence of nanotechnological therapeutic agents in the clinic. A pegylated form of liposomally encapsulated doxorubicin is routinely used for treatment against metastatic cancer, and albumin nanoparticulate chaperones of paclitaxel were approved for locally recurrent and metastatic disease in 2005. These drugs have yielded substantial clinical benefit, and are steadily gathering greater beneficial impact. Clinical trials currently employing these drugs in combination with chemo and biological therapeutics exceed 150 worldwide. Despite these advancements, breast cancer morbidity and mortality is unacceptably high. Nanotechnology offers potential solutions to the historical challenge that has rendered breast cancer so difficult to contain and eradicate: the extreme biological diversity of the disease presentation in the patient population and in the evolutionary changes of any individual disease, the multiple pathways that drive disease progression, the onset of 'resistance' to established therapeutic cocktails, and the gravity of the side effects to treatment, which result from generally very poor distribution of the injected therapeutic agents in the body. A fundamental requirement for success in the development of new therapeutic strategies is that breast cancer specialists-in the clinic, the pharmaceutical and the basic biological laboratory-and nanotechnologists-engineers, physicists, chemists and mathematicians-optimize their ability to work in close collaboration. This further requires a mutual openness across cultural and language barriers, academic reward systems, and many other 'environmental' divides. This paper is respectfully submitted to the community to help foster the mutual interactions of the breast cancer world with micro- and nano-technology, and in particular to encourage the latter community to direct ever increasing attention to breast cancer, where an extraordinary beneficial impact may

    Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

    Breast cancer is one of the most common malignancies affecting pregnancy. Pregnancy-associated breast cancer refers to breast cancer that is diagnosed during pregnancy or within the first postpartum year. The incidence is increasing as more women delay childbearing. Breast cancer can be safely diagnosed, staged, and treated during pregnancy while protecting the fetus and mother with excellent outcomes for both. Avoiding diagnostic delays is vital to prognosis. This article provides an overview of the diagnosis, staging, management, and prognosis of pregnancy-associated breast cancer. Relevant current literature is reviewed.

    Purpose: Older women with early-stage disease constitute the most rapidly growing breast cancer demographic, yet it is not known which local therapy strategies are most favored by this population in the current era. Understanding utilization trends and cost of local therapy is important for informing the design of bundled payment models as payers migrate away from fee-for-service models. We therefore used the Surveillance, Epidemiology, and End Results Medicare database to determine patterns of care and costs for local therapy among older women with breast cancer. Methods and Materials: Treatment strategy and covariables were determined in 55,327 women age ≥66 with Tis-T2N0-1M0 breast cancer who underwent local therapy between 2000 and 2008. Trends in local therapy were characterized using Joinpoint. Polychotomous logistic regression determined predictors of local therapy. The median aggregate cost over the first 24 months after diagnosis was determined from Medicare claims through 2010 and reported in 2014 dollars. Results: The median age was 75. Local therapy distribution was as follows: 27,896 (50.3%) lumpectomy with external beam radiation, 18,356 (33.1%) mastectomy alone, 6159 (11.1%) lumpectomy alone, 1488 (2.7%) mastectomy with reconstruction, and 1455 (2.6%) lumpectomy with brachytherapy. Mastectomy alone declined from 39.0% in 2000 to 28.2% in 2008, and the use of breast conserving local therapies rose from 58.7% to 68.2%. Mastectomy with reconstruction was more common among the youngest, healthiest patients, whereas mastectomy alone was more common among patients living in rural low-income regions. By 2008, the costs were $36,749 for lumpectomy with brachytherapy, $35,030 for mastectomy with reconstruction, $31,388 for lumpectomy with external beam radiation, $21,993 for mastectomy alone, and $19,287 for lumpectomy alone. Conclusions: The use of mastectomy alone in older women declined in favor of breast conserving strategies between 2000 and 2008

    2017-01-01

    Breast cancer recurrence represents a challenge for clinicians because the management is not standardized and usually requires a multidisciplinary approach. This is the key for a good long term disease control and for a management with curative intent. The local recurrence in breast cancer appears after breast conserving treatment (BCT) or after mastectomy, and the regional recurrence involves the ipsilateral axillary, internal mammary or supraclavicular lymph nodes. Local recurrence prognosis after BCT seems to be better than after mastectomy regarding distant metastases occurrence and overall survival. Prognosis of axillary recurrence is better than prognosis of supraclavicular and internal mammary recurrence. Locoregional recurrence in breast cancer represents rather a marker for the appearance of distant metastases than a determinant factor for them. Management options for locoregional recurrence of cancer require multidisciplinary input decision making and for this reason the multidisciplinary tumor-board (MTD) is very important. Each patient should receive the best individualized oncologic treatment. Celsius.

    A literature review was performed on intraoperative radiotherapy of breast cancer. The strength and attractiveness is established of techniques of partial irradiation in the treatment of breast cancer. The benefit is originated to restrict the area immediate of radiotherapy to the tumor bed or quadrant index and identifying the benefit of being applied during the radiotherapy while surgical lumpectomy. The impact of local recurrence has been established using intraoperative radiotherapy. The advantages of intraoperative radiotherapy was compared in the management of the conservative surgery in early stages of breast cancer with external radiotherapy. Different methods of intraoperative radiotherapy have been compared and individual impact on local recurrence ranges. Intraoperative radiotherapy has had many advantages: radiobiological, technical, clinical, psychological and economical in the handling of conservative surgery in early stages of breast cancer, compared with external radiotherapy [es

    Purpose: Primary radiation therapy following breast-conserving surgery has been an accepted alternative to mastectomy in Europe and North America for many years. In Australia, however, the history of breast conservation for early invasive breast cancer is much shorter. The purpose of this study was to evaluate the results of breast conservation in a state-wide Australian radiotherapy service. Methods and Materials: Between January 1982 and December 1989, 512 patients were treated with primary radiation therapy after breast conserving surgery. This analysis is based on a review of these patients, all of whom had Stage I or II breast cancer. Results: With a median follow-up of 50 months, the 5-year actuarial rate of overall survival was 84% and disease-free survival was 80%. There have been 22 isolated local recurrences in the breast. The time to an isolated breast recurrence ranged from 12 to 83 months (median, 26 months). The 5-year actuarial rate of an isolated breast recurrence was 4%. The recurrence rate was higher for patients with involved margins (15% vs. 2%, p < 0.01). Local recurrence was also more likely in the presence of extensive ductal carcinoma insitu (DCIS), as opposed to no extensive DCIS (10% vs. 2%, p < 0.01). Conclusion: These results affirm that primary radiation therapy after breast conserving surgery in Queensland, has been given with a low rate of local recurrence, comparable to that obtained in other centers

    To assess the ablative effectiveness, the oncological and cosmetic efficacy of image-guided percutaneous cryoablation in the treatment of single breast nodules with subclinical dimensions after identification with ultrasonography (US), mammography, magnetic resonance (MRI) and characterization by vacuum assisted biopsy. Fifteen women with a mean age of 73 {+-} 5 years (range 64-82 years) and lesion diameter of 8 {+-} 4 mm were undergoing cryotherapy technology with a single probe under US-guidance associated with intra-procedural lymph-node mapping and excision of the sentinel node. All the patients underwent surgical resection (lumpectomy) from 30 to 45 days after the percutaneous ablation. The iceball size generated by the cryoprobe during the procedure at minus 40 C was 16 x 41 mm. In 14 of the 15 patients was observed a complete necrosis of the cryo-ablated lesion both in post-procedural MRI follow-up and anatomo-pathological evaluation after surgical resection. In one case there was a residual disease in post-procedural MRI and postoperative histological examination, probably justified by an incorrect positioning of the probe. The percutaneous cryoablation as a ''minimally invasive'' technique can provide excellent oncological and cosmetic results on selected cases handled by experienced operators by using the tested devices.

    Of 354 patients undergoing radiotherapy up to 31 Dec 1982, 268 comparable cases were examined with regard to local recurrences, metastases, and general health status. The incidence of local recurrences suggested a higher efficiency of this technique as compared with the formerly applied technique of 4-field high-voltage therapy. Medial or central tumours were found to have an almost significantly loss favourable prognosis, which suggests a first spread remote metastases via the parastermal lymphatic vessels. The other 86 patients were analyzed descriptively according to subgroups. Radiolesions of the skin and lungs were not significantly less or more frequent than with other radiotherapies. Electron cineroentgenotherapy is well tolerated even by pre-exposed skin: The Tuebingen experience so far proves the acceptability of the new technique. (orig./MG) [de

    Insulin-like growth factor-I (IGF-I) in concert with insulin-like binding protein 3 (IGFBP-3), insulin-like binding protein 2 (IGFBP-2), human growth hormone (GH) and P53 protein is involved in autocrine/paracrine growth signaling pathways as an adaptive response to environmental stimuli. The study evaluated the local secretion of PRL, hGH, IGF-I, IGFBP-2 and IGFBP-3 by breast cancer tissue explants in relation to the overexpression of P53 protein in breast cancer tissue. Breast cancer explants were obtained during radical mastectomies. The overexpression of P53 protein was assessed immunohistochemically using monoclonal antibody (DAKO, Anti-Human P53 protein, clone DO-7); the results of the reaction were stratified into 5 groups. The lack of P53 protein overexpression was defined as 0% of cells that overexpressed P53 protein. IGF-I, IGFBP-3, IGFBP-2, and hGH levels were measured with RIA kits, and prolactin was measured with the MEIA kit. The local secretion of hGH by tumour explants - presenting a positive immunohistochemical reaction (IHCR) to the product of P53 gene - was twice as high as those with no IHCR to product of P53 gene; the opposite was noted in the case of IGF-I, IGFBP-2 and IGFBP-3 secretion. In both cases, the level of hGH, IGF-I and IGFBP-3 secretion did not correlate with the ratio of cells overexpressing P53 protein. There was a significant decrease in local, basic IGFBP-2 secretion along with an increased ratio of cells with positive IHCR to product of P53 gene. Furthermore, local PRL secretion was not correlated with the ratio of cells overexpressing P53 protein in breast cancer tissue. Prolactin also exerts no influence on IGF-I secretion. Our results may suggest the presence of local hGH/IGF-I feedback in breast tissue as well as the possibility of P53/hGH/IGF-I/IGFBP-3 but not P53/PRL/IGF-I axis.

    The possible role of radiation as a factor in the causation of breast cancer was investigated. Some variables said to be associated with a high risk of breast cancer include genetic factors, pre-existing breast disease, artificial menopause, family history of breast cancer, failure to breast feed, older than usual age at time of first pregnancy, high socioeconomic status, specific blood groups, fatty diet, obesity, and hormonal imbalances. To this list we must add ionizing radiation as an additional and serious risk factor in the causation of breast cancer. Among the irradiated groups which have an increase in the incidence of cancer of the breast are: tuberculous women subjected to repeated fluoroscopy; women who received localized x-ray treatments for acute post-partum mastitis; atom-bomb survivors; other x-ray exposures involving the breast, including irradiation in children and in experimental animals; and women who were treated with x rays for acne or hirsuitism. The dose of radiation received by the survivors of the atom bomb who subsequently developed cancer of the breast ranged from 80 to 800 rads, the tuberculous women who were fluoroscoped received an estimated 50 to 6,000 rads, the women who were treated for mastitis probably were exposed to 30 to 700 rads, and the patients with acne received 100 to 6,000 rads. These imprecise estimates are compared with mammographic doses in the range of 10s of rads to the breast at each examination, an imprecise estimate depending on technique and equipment. However imprecise these estimates may be, it is apparent that younger women are more likely than older women to develop cancer from exposure to radiation. It is pointed out that the American Cancer Society advises that women under 35 years should have mammography only for medical indication, not for so-called screening

    Conservative surgery can be regarded as the standard treatment for most early stage breast tumors. However, a minority of patients treated with conservative surgery will present local or locoregional recurrence. Therefore, it is of interest to evaluate the possible factors associated with this recurrence. A population-based retrospective study using data from the Tumor Registry of Castellón (Valencia, Spain) of patients operated on for primary nonmetastatic breast cancer between January 2000 and December 2008 was designed. Kaplan-Meier curves and log-rank test to estimate 5-year local recurrence were used. Two groups of patients were defined, one with conservative surgery and another with nonconservative surgery. Cox multivariate analysis was conducted. The total number of patients was 410. Average local recurrence was 6.8%. In univariate analysis, only tumor size and lymph node involvement showed significant differences. On multivariate analysis, independent prognostic factors were conservative surgery (hazard ratio [HR] 4.62; 95% confidence interval [CI]: 1.12-16.82), number of positive lymph nodes (HR 1.07; 95% CI: 1.01-1.17) and tumor size (in mm) (HR 1.02; 95% CI: 1.01-1.06). Local recurrence after breast-conserving surgery is higher in tumors >2 cm. Although tumor size should not be a contraindication for conservative surgery, it should be a risk factor to be considered.

    Summary Reproduction is doubtlessly one of the main biological meanings of life. It is therefore not surprising that various aspects of reproduction impact on breast cancer risk. Various developmental levels may become targets of breast tumorigenesis. This review follows the chronologic sequence of events in the life of a female at risk, starting with the intrauterine development. Furthermore, the influence of both contraceptive measures and fertility treatment on breast cancer development is dealt with, as well as various pregnancy-associated factors, events, and perinatal outcomes. Finally, the contribution of breast feeding to a reduced breast cancer risk is discussed. PMID:25759622

    Conventional imaging modalities provide only morphological details and do not provide information on the metabolic status of a lesion, which is very important in differentiating a benign from a malignant lesion. Early diagnosis and reliable imaging assessment of response to treatment are essential in the clinical management of breast cancer. Positron Emission Tomography (PET) has been widely shown to be highly useful for the diagnosis of palpable masses, for staging, for obtaining long-term prognostic information, and for demonstrating tumour response to chemotherapy at an early phase or after completion of treatment in patient with breast cancer. Twenty-three consecutive female patients with primary breast carcinoma (T3/T4,N2,M0) were prospectively recruited for AT--TDG and tumour 18F-IDG update (standardized update value, SUV was used as a metabolic indicator. There was a positive relationship between tumour metabolic and response to chemotherapy and pathological conditions SUV provides an index of regional tracer uptake and a reduced SUV are indicative of tumour regression.

    Background and purpose: the purpose of this sequential intervention study was to determine the rate of local recurrences and the rate of distant metastases in patients with invasive breast cancer who had been treated with breast-conserving surgery and postoperative radiation therapy to the whole breast either with postoperative electron boost in group 1 or with intraoperative electron boost (IORT) in group 2. Patients and methods: after breast-conserving surgery, 378 women with invasive breast cancer of tumor sizes T1 and T2 received 51-56.1 gy of postoperative radiation therapy to the whole breast in 1.7-gy fractions. 188 of those patients additionally received a postoperative electron boost of 12 gy in group 1 from January 1996 to October 1998. Consecutively, from October 1998 to March 2001, 190 patients received intraoperative electron-boost radiotherapy of 9 gy to the tumor bed in group 2. The groups were comparable with regard to age, menopausal status, tumor size, grading, and nodal status. All statistical tests were two-sided. Results: during a median follow-up period of 55.3 months in group 1 and 25.8 months in group 2, local recurrences were observed in eight of 188 patients (4.3%) in group 1, and no local recurrence was seen in group 2 (p = 0.082). Distant metastases occurred in 15 of the 188 patients (7.9%) in group 1 and in two of the 190 patients (1.1%) in group 2 (p = 0.09). The 4-year actuarial rates of local recurrence were 4.3% (95% confidence interval, 1.8-8.2%) and 0.0% (95% confidence interval, 0.0-1.9%) and the 4-year actuarial rates of distant metastases were 7.9% (95% confidence interval, 4.5-12.8%) and 1.1% (95% confidence interval, 0.1-3.8%). Conclusion: immediate IORT boost yielded excellent local control figures in this prospective investigation and appears to be superior to conventional postoperative boost in a short-term follow-up.

    Full Text Available The investigation enrolled 31 patients with inflammatory breast cancer (IBC treated at the N. N. Blokhin Cancer Research Center from 2006 to 2008. IBC is diagnosed on the basis of signs of rapid progression, such as localized or generalized breast induration, red- ness and edema. IBC accounts for less than 5% of all diagnosed breast cancers and is the most lethal form of primary breast cancer. We studied tumor markers of the immunophenotype of IBC and levels and subpopulations of immunocompetent tumor-infiltrating cells. We found that expression of HLA-DR is in negative correlation with MUC-1 expression and lymphoid cells tumor infiltration is asso- ciated with the increase in T-cell subpopulations.

    This is the first textbook of its kind devoted to describing the biological complexities of breast cancer in a way that is relevant to the radiation oncologist. Radiation Oncology has long treated breast cancer as a single biological entity, with all treatment decisions being based on clinical and pathologic risk factors. We are now beginning to understand that biological subtypes of breast cancer may have different risks of recurrence as well as different intrinsic sensitivity to radiotherapy. Multi-gene arrays that have for years been used to predict the risk of distant recurrence and the value of systemic chemotherapy may also have utility in predicting the risk of local recurrence. Additionally, the targeted agents used to treat breast cancer may interact with radiotherapy in ways that can be beneficial or undesirable. All of these emerging issues are extensively discussed in this book, and practical evidence-based treatment recommendations are presented whenever possible.

    The objective of this study was to compare the effect of thoracic paravertebral block (TPVB) and local anesthetic (LA) on persistent postoperative pain (PPP) 1 year following breast cancer surgery. Secondary objectives were to compare the effect on arm morbidity and quality of life. Women scheduled for elective breast cancer surgery were randomly assigned to either TPVB or LA followed by general anesthesia. An NRS value of >3 at rest or with movement 1 year following surgery defined PPP. Blinded interim analysis suggested rates of PPP much lower than anticipated, making detection of the specified 20 % absolute reduction in the primary outcome impossible. Recruitment was stopped, and all enrolled patients were followed to 1 year. A total of 145 participants were recruited; 65 were randomized to TPVB and 64 to LA. Groups were similar with respect to demographic and treatment characteristics. Only 9 patients (8 %; 95 % CI 4-14 %) met criteria for PPP 1 year following surgery; 5 were in the TPVB and 4 in the LA group. Brief Pain Inventory severity and interference scores were low in both groups. Arm morbidity and quality of life were similar in both groups. The 9 patients with PPP reported shoulder-arm morbidity and reduced quality of life. This study reports a low incidence of chronic pain 1 year following major breast cancer surgery. Although PPP was uncommon at 1 year, it had a large impact on the affected patients' arm morbidity and quality of life.

    Histone deacetylases (HDACs) are a family of enzymes that regulate chromatin remodeling and gene transcription. Vorinostat is a panHDAC inhibitor that sensitizes breast cancer cells to taxanes and trastuzumab by suppressing HDAC6 and Hsp90 client proteins. Fifty-five patients with clinical stage IIA-IIIC breast cancer received 12 weekly doses of paclitaxel (80 mg/m(2)) plus vorinostat (200-300 mg PO BID) on days 1-3 of each paclitaxel dose plus trastuzumab (for Her2/neu positive disease only), followed by doxorubicin/cyclophosphamide (60/600 mg/m(2) every 2 weeks plus pegfilgrastim). The primary study endpoint was pathologic complete response (pCR). pCR occurred in 13 of 24 evaluable patients with Her2-positive disease (54, 95 % confidence intervals [CI] 35-72 %), which met the prespecified study endpoint. pCR occurred in 4 of 15 patients with triple negative disease (27, 95 % CI 11-52 %) and none of 12 patients with ER-positive, Her2/neu negative disease (0, 95 % CI 0-24 %), which did not meet the prespecified endpoint. ER-positive tumors exhibited lower Ki67 and higher Hsp70 expression, and HDAC6, Hsp70, p21, and p27 expression were not predictive of response. Vorinostat increased acetylation of Hsp90 and alpha tubulin, and reduced expression of Hsp90 client proteins and HDAC6 in the primary tumor. Combination of vorinostat with weekly paclitaxel plus trastuzumab followed by doxorubicin-cyclophosphamide is associated with a high pCR rate in locally advanced Her2/neu positive breast cancer. Consistent with cell line and xenograft data, vorinostat increased acetylation of Hsp90 and alpha tubulin, and decreased Hsp90 client protein and HDAC6 expression in human breast cancers in vivo.

    Full Text Available In this review, we summarize the epidemiologic evidence for the associations of oral contraceptives and postmenopausal hormones with risk of breast cancer. We also describe the biologic plausibility of these relationships. Overall, there appears to be little, if any, increase in risk with oral contraceptive use in general, even among users for 10 or more years. However, compared to never users, current oral contraceptive users appear to have a modest elevation in risk that subsides within about 10 years after cessation of use. For postmenopausal hormones, the weight of the evidence suggests little or no increase in risk among users of short duration, or for use in the past. However, current longer term use is associated with an increased risk of breast cancer that increases with duration. This increase in risk is large enough, and well enough supported, to be considered along with the other risks and benefits of postmenopausal hormone therapy.

    Full Text Available Accessory breast tissue results from failure of the embryologic mammary ridge, also known as the milk line, to involute. As a result, ectopic breast tissue can develop anywhere along this ridge, which extends from the axilla—the most common location—to the groin. Primary breast cancer in accessory breast tissue is uncommon but has been reported in multiple prior studies. We present a rare case of inflammatory breast cancer presenting in upper abdominal accessory breast tissue in women with a personal history of ipsilateral breast cancer, and highlight the challenges of both diagnosis and treatment of breast cancer in accessory breast tissue.

    Being a significant health problem that affects patients in various age groups, breast cancer has been extensively studied to date. Recently, molecular breast cancer classification has advanced significantly with the availability of genomic profiling technologies. Proteomic technologies have also advanced from traditional protein assays including enzyme-linked immunosorbent assay, immunoblotting and immunohistochemistry to more comprehensive approaches including mass spectrometry and reverse phase protein lysate arrays (RPPA). The purpose of this manuscript is to review the current protein markers that influence breast cancer prediction and prognosis and to focus on novel advances in proteomic classification of breast cancer.

    Though about 20% of working age breast cancer survivors do not return to work after treatment, few studies have addressed risk factors for unemployment. The majority of studies on occupational consequences of breast cancer focus on non-employment, which is a mixture of sickness absence, unemployment, retirement pensions and other reasons for not working. Unemployment in combination with breast cancer may represent a particular challenge for these women. The aim of the present study is therefore to analyze the risk for unemployment in the years following diagnosis and treatment for breast cancer. This study included 14,750 women diagnosed with breast cancer in Denmark 2001-2009 identified through a population-based clinical database and linked with information from Danish administrative population based registers for information on labour market affiliation, socio-demography and co-morbid conditions. Multivariable analyses were performed by Cox's proportional hazard models. Two years after treatment, 81% of patients were still part of the work force, 10% of which were unemployed. Increasing duration of unemployment before breast cancer was associated with an adjusted HR = 4.37 (95% CI: 3.90-4.90) for unemployment after breast cancer. Other risk factors for unemployment included low socioeconomic status and demography, while adjuvant therapy did not increase the risk of unemployment. Duration of unemployment before breast cancer was the most important determinant of unemployment after breast cancer treatment. This allows identification of a particularly vulnerable group of patients in need of rehabilitation.

    PURPOSE: To evaluate outcome of patients with bilateral breast cancer as compared to unilateral breast cancer treated with breast conservation therapy. This is a complex issue, however, we address this by comparing (1) synchronous bilateral breast cancer patients, (2) metachronous bilateral breast cancer patients from the time of diagnosis of the second breast primary, and (3) unilateral breast cancer patients. The authors recognize that there are inherent biases in these comparisons. MATERIALS AND METHODS: A total of 60 bilateral patients and 1080 unilateral patients treated with breast conservation therapy from 1977-1994 were analyzed for outcome. Of the 60 bilateral patients, 44 were metachronous bilateral breast cancer patients (MBBC) and 16 were synchronous breast cancer patients (SBBC). Patients with bilateral breast cancer had local-regional disease with the following tumor stages: DCIS=8%, T1=80%, T2=12%, pathologic N0=90%, pathologic N+=10%. Unilateral patients had the following tumor stages: DCIS=10%, T1=66%, T2=20%, T3=1.2%, Tx=2%, pathological N0=80%, pathological N+=19%, and NX=1%. The majority of patients received lumpectomy and axillary node dissection followed by radiation therapy. The median size of the lesions were 1.4cm and 1.5cm for bilateral and unilateral patients, respectively. Median total dose to the primary tumor was 60Gy for both unilateral and bilateral patients. Of the 44 metachronous bilateral breast cancer patients, 14 patients received breast conservation for both the first and second lesions while 30 patients had breast conservation for only the second metachronous breast lesion. Thus 58 lesions in the 44 patients were treated with breast conservation therapy in the patients with metachronous bilateral breast cancer. Of the synchronous bilateral breast cancer patients, 13 out of 16 patients had breast conserving therapy for both breasts, and 3 patients received mastectomy for the second synchronous breast tumor. The median follow

    In situ breast cancer, particularly the ductal type, is increasing in frequency in the developed countries as well as in Ecuador, most probably. These lesions carry a higher risk of developing a subsequent invasive cancer. Treatment has changed recently due to results of randomized studies, from classical mastectomy to conservative surgery associated to radiotherapy. The Van Nuys Prognostic Index is currently the most usual instrument to guide diagnosis and treatment. Tamoxifen seems to decrease significantly the risk of tumor recurrence after initial treatment.

    Full Text Available Inflammatory cytokines within the tumor microenvironment are linked to progression in breast cancer. Interleukin- (IL- 19, part of the IL-10 family, contributes to a range of diseases and disorders, such as asthma, endotoxic shock, uremia, psoriasis, and rheumatoid arthritis. IL-19 is expressed in several types of tumor cells, especially in squamous cell carcinoma of the skin, tongue, esophagus, and lung and invasive duct carcinoma of the breast. In breast cancer, IL-19 expression is correlated with increased mitotic figures, advanced tumor stage, higher metastasis, and poor survival. The mechanisms of IL-19 in breast cancer have recently been explored both in vitro and in vivo. IL-19 has an autocrine effect in breast cancer cells. It directly promotes proliferation and migration and indirectly provides a microenvironment for tumor progression, which suggests that IL-19 is a prognostic marker in breast cancer and that antagonizing IL-19 may have therapeutic potential.

    Following mastectomy and adjuvant external beam radiation therapy in patients with breast cancer, the incidence of local or locoregional recurrence is approximately 9 % (2-20 %). Alongside the often limited possibilities of surgical treatment, radiation therapy combined with superficial hyperthermia is the most effective local therapy. In the present work, a retrospective analysis of salvage brachytherapy combined with superficial hyperthermia for chest wall recurrences is presented. Between 2004 and 2011, 18 patients with a total of 23 target volumes resulting from chest wall recurrences after previously mastectomy and external beam radiation therapy (median 56 Gy, range 50-68 Gy) were treated with superficial brachytherapy as salvage treatment: 8 patients (44 %) had macroscopic tumor, 3 (17 %) had microscopic tumor (R1), and 7 (39 %) had undergone R0 resection and were treated due to risk factors. A dose of 50 Gy was given (high-dose rate [HDR] and pulsed-dose rate [PDR] procedures). In all, 5 of 23 patients (22 %) received additional concurrent chemotherapy, and in 20 of 23 (87 %) target volumes additional superficial hyperthermia was carried out twice weekly. The 5-year local recurrence-free survival was 56 %, the disease-free survival was 28 %, and a 5-year overall survival was 22 %. Late side effects Common Toxicity Criteria (CTC) grade 3 were reported in 17 % of the patients: 2 of 18 (11 %) had CTC grade 3 fibrosis, and 1 of 18 (6 %) had a chronic wound healing disorder. Re-irradiation as salvage brachytherapy with superficial hyperthermia for chest wall recurrences is a feasible and safe treatment with good local control results and acceptable late side effects.

    Purpose: To compare long-term late local toxicity after either concomitant or sequential chemoradiation therapy after breast-conserving surgery. Methods and Materials: From 1997 to 2002, women aged 18 to 75 years who underwent breast-conserving surgery and axillary dissection for early breast cancer and in whom CMF (cyclophosphamide, methotrexate, and 5-fluorouracil) chemotherapy was planned were randomized between concomitant and sequential radiation therapy. Radiation therapy was delivered to the whole breast through tangential fields to 50 Gy in 20 fractions over a period of 4 weeks, followed by an electron boost. Surviving patients were tentatively contacted and examined between March and September 2014. Patients in whom progressive disease had developed or who had undergone further breast surgery were excluded.

    Purpose: To compare long-term late local toxicity after either concomitant or sequential chemoradiation therapy after breast-conserving surgery. Methods and Materials: From 1997 to 2002, women aged 18 to 75 years who underwent breast-conserving surgery and axillary dissection for early breast cancer and in whom CMF (cyclophosphamide, methotrexate, and 5-fluorouracil) chemotherapy was planned were randomized between concomitant and sequential radiation therapy. Radiation therapy was delivered to the whole breast through tangential fields to 50 Gy in 20 fractions over a period of 4 weeks, followed by an electron boost. Surviving patients were tentatively contacted and examined between March and September 2014. Patients in whom progressive disease had developed or who had undergone further breast surgery were excluded. Local toxicity (fibrosis, telangiectasia, and breast atrophy or retraction) was scored blindly to the treatment received. A logistic regression was run to investigate the effect of treatment sequence after correction for several patient-, treatment-, and tumor-related covariates on selected endpoints.

    According to the American Cancer Society in 2007, about 178,000 women are diagnosed with breast cancer each year in the United States. Of these, 25% have tumors in their childbearing years and may desire future opportunities for pregnancy and lactation. Although there is a multitude of options related to preserving fertility, little is known about the residual effects of breast cancer treatment and the ability to breast-feed afterward. This article describes the epidemiological relationship between breast cancer and pregnancy and lactation. Basic types of treatment for breast cancer including surgery, chemotherapy, and radiation are reviewed. Practical information on how to support breast-feeding after breast cancer is included.

Triple negative breast cancer (TNBC is a recently identified biological variant with aggressive tumor behavior and poor prognosis. Data of hormonal status from the Indian population is scarce due to financial constraints in performing immunohistochemistry evaluation. The present study aims to prospectively analyze receptor status of all breast cancer patients and identify TNBC and compare their clinical profile and short term survival with other non-TNBC group. Materials and methods: All cytologically and histopathologically confirmed cases of carcinoma breast were prospectively enrolled. In a longitudinal study at tertiary care hospital in central India based on the hormonal status, they were further divided into TNBC and other groups. Comparison of risk factors, clinical profile and short-term survival was carried out. Results: A total 85 patients were enrolled and of them 37 (43.7% were TNBC. On comparing risk factors ie, age, age at menarche, total reproductive age, age at first child birth, and menopausal status – no statistical significance was observed between the TNBC and non-TNBC groups. But on comparison of clinical profile TNBC tumors were significantly large with majority of patients presenting as locally advanced breast cancer (83%. No statistical difference was observed in axillary lymph node status between two groups. TNBC tumors were histologically more aggressive (grade 3 compared to other groups. No statistically significant difference was observed in short term overall survival but all three deaths were observed in the TNBC group only and two local recurrences after surgery were observed in the TNBC group. Conclusion: TNBC forms a large proportion of carcinoma breast patients in a central

    This retrospective study involved 463 breast cancer patients treated by radiotherapy alone at the Princess Margaret Hospital and at the Institut Gustave-Roussy. These patients either had operable tumors, but were unfit for general anesthesia, or had inoperable tumors due to local contraindications to surgery. Results were analyzed according to tumor response, local recurrence rate, tumor size, tumor fixation, nodal fixation and tumor dose. Conventional statistical analysis of local control showed two significant factors: tumor dose and tumor size. Multivariate analysis permitted to define an ''individual risk'' (IR) of local recurrence according to three independent factors: tumor size, tumor fixation, and nodal fixation. It was shown that the IR was a good prognostic factor for local control. Increase in tumor dose gave a similar effect in the local recurrence relative risk for all the IR groups. According to the slope of the dose-effect curve, it was deduced that a dose increase of 15 Gy can decrease the relative risk of local recurrence 2-fold. In fact, it was shown that tumor dose was the most significant independent factor on local control, able to produce up to a 10-fold increase compared to 2-fold decrease for tumor size. If the IR of local recurrence is known, a theoretical predictive value on local control, taking into account the tumor dose, can be determined according to the present data

    Localization of the tumor bed of breast cancer is crucial for accurate planning of boost irradiation. Lumpectomy cavity and surgical clips provide localizing information about tumor bed. However, defining the tumor bed is often difficult because of presence of unclear lumpectomy cavity and lack of certain information such as absence of surgical clips. In the present study, we evaluated the feasibility of initial diagnostic PET-CT in localization of the tumor bed using deformable image registration (DIR). We selected twenty-five patients who had an initial diagnostic PET-CT performed and underwent breast-conserving surgery with surgical clips in tumor bed. In every individual patient, two target volumes were separately delineated on planning CT; 1) target volume based on surgical clips with a margin of 1 cm (TV clip ) and 2) tumor volume based on 90% of maximum SUV on PET-CT registered by DIR (TV PET ). The percent of TV PET in TV clip (V in ) was calculated and distance between center points of two volumes (D center ) was also measured. Mean D center between two volumes was 1.4 cm (range, 0.33 – 2.53). Mean V in was 94.8% (range, 60.9-100) and 100% in 18 out of 25 patients. When compared to the center of TV clip , the center of TV PET tended to be located posteriorly (mean 0.3 cm, standard deviation 0.6), laterally (mean 0.3 cm, standard deviation 0.8) and inferiorly (mean 0.4 cm, standard deviation 0.9). Initial diagnostic PET-CT can be one of the possible references to localize the tumor bed in breast cancer radiotherapy

    Axillary node dissection has a central role in the surgical management of breast cancer; however, it is associated with a significant risk of lymphoedema and chronic pain. Peri-operative administration of local anesthesia reduces acute and persistent post-surgical pain, but there is currently no consensus on the optimal method of local anesthetic delivery. Patients undergoing axillary dissection for breast cancer were randomly assigned to receive a one-off dose of levobupivacaine 0.5% (up to 2 mg/kg) following surgery, either via the surgical drain or by direct skin infiltration. Post-operative pain control at rest and on shoulder abduction was assessed using a numerical rating scale. Total analgesia consumption 48 h after surgery was also recorded. Pain scores were significantly lower when local anesthesia was administered via surgical drain at both 3 and 12 h after surgery; this trend extended to 24 h post-operatively. However, pain scores on shoulder abduction did not differ at the 12 or 24 h time points. No differences were found in the total analgesia consumption or length of hospital stay between treatment groups. This study demonstrates that local anesthetic delivery via a surgical drain provides improved pain control compared to direct skin infiltration following axillary node dissection. This is likely to be important for the management of acute pain in the immediate post-operative period; however, further studies may be required to validate this in specific patient subgroups, e.g., breast-conserving surgery versus mastectomy.

    Purpose: Conventional radiation fractionation of 1.8-2 Gy per day for early stage breast cancer requires daily treatment for 6-7 weeks. We report the 5-year results of a phase II study of intensity modulated radiation therapy (IMRT), hypofractionation, and incorporated boost that shortened treatment time to 4 weeks. Methods and Materials: The study design was phase II with a planned accrual of 75 patients. Eligibility included patients aged {>=}18 years, Tis-T2, stage 0-II, and breast conservation. Photon IMRT and an incorporated boost was used, and the whole breast received 2.25 Gy per fraction for a total of 45 Gy, and the tumor bed received 2.8 Gy per fraction for a total of 56 Gy in 20 treatments over 4 weeks. Patients were followed every 6 months for 5 years. Results: Seventy-five patients were treated from December 2003 to November 2005. The median follow-up was 69 months. Median age was 52 years (range, 31-81). Median tumor size was 1.4 cm (range, 0.1-3.5). Eighty percent of tumors were node negative; 93% of patients had negative margins, and 7% of patients had close (>0 and <2 mm) margins; 76% of cancers were invasive ductal type: 15% were ductal carcinoma in situ, 5% were lobular, and 4% were other histology types. Twenty-nine percent of patients 29% had grade 3 carcinoma, and 20% of patients had extensive in situ carcinoma; 11% of patients received chemotherapy, 36% received endocrine therapy, 33% received both, and 20% received neither. There were 3 instances of local recurrence for a 5-year actuarial rate of 2.7%. Conclusions: This 4-week course of hypofractionated radiation with incorporated boost was associated with excellent local control, comparable to historical results of 6-7 weeks of conventional whole-breast fractionation with sequential boost.

    Increasing use of IMRT to treat breast and prostate cancers at high risk of regional nodal spread relies on accurate contouring of targets and organs at risk, which is subject to significant inter- and intra-observer variability. This study sought to evaluate the performance of an atlas based deformable registration algorithm to create multi-patient CT based atlases for automated contouring. Breast and prostate multi-patient CT atlases (n = 50 and 14 respectively) were constructed to be consistent with RTOG consensus contouring guidelines. A commercially available software algorithm was evaluated by comparison of atlas-predicted contours against manual contours using Dice Similarity coefficients. High levels of agreement were demonstrated for prediction of OAR contours of lungs, heart, femurs, and minor editing required for the CTV breast/chest wall. CTVs generated for axillary nodes, supraclavicular nodes, prostate, and pelvic nodes demonstrated modest agreement. Small and highly variable structures, such as internal mammary nodes, lumpectomy cavity, rectum, penile bulb, and seminal vesicles had poor agreement. A method to construct and validate performance of CT-based multi-patient atlases for automated atlas based auto-contouring has been demonstrated, and can be adopted for clinical use in planning of local regional breast and high-risk prostate radiotherapy.

    Abstract Background: Concurrent chemoradiotherapy could increase the local control rate in patients with high recurrence risk after breast-conserving surgery, but the effect of concurrent chemoradiotherapy after mastectomy and axillary dissection is not clear. The aim of the study was to compare the effects of late-course concurrent chemoradiotherapy (CCRT) versus sequential therapy (SCRT) after mastectomy and axillary surgery in locally advanced breast cancer. Methods: This was a randomized controlled trial of 155 patients with stage pT3–4p N1–3c M0 or pAnyT pN2–3c M0 breast cancer undergoing 5-fluorouracil+epirubicin+cyclophosphamide followed by docetaxel (FEC-D) chemotherapy after mastectomy and axillary dissection. Patients were randomized to the CCRT group (intensity-modulated radiation therapy was performed concurrently with docetaxel) or to the SCRT group (radiotherapy after chemotherapy). Recurrences, adverse reactions, and short-term effects were observed. Results: All the patients completed the planned therapy. The median follow-up was 39 (range, 16–62) months. Compared with SCRT, the 3-year local-regional recurrence-free survival (LRFS) in the CCRT group was improved (81.8% vs 92.3%, P = .046). There was no significant difference in 3-year disease-free survival (DFS) and overall survival (OS). In the pT3–4 pN1–3 cM0 subgroup, the 3-year local recurrence-free survival and DFS were significantly improved in the CCRT group (69.4% vs 88.2%, P = .036; and 41.7% vs 72.6%, P = .049, respectively). No significant difference was observed adverse reactions between the 2 groups. Conclusion: LRFS of patients with locally advanced invasive breast cancer after mastectomy and axillary surgery was better with CCRT than with SCRT and with similar profiles of adverse reactions. The DFS of patients staged pT3–4 pN1–3 cM0 was also improved. PMID:29019894

    Purpose To investigate nuclear localized and tyrosine phosphorylated Stat5 (Nuc-pYStat5) as a marker of prognosis in node-negative breast cancer and as a predictor of response to antiestrogen therapy. Patients and Methods Levels of Nuc-pYStat5 were analyzed in five archival cohorts of breast cancer by traditional diaminobenzidine-chromogen immunostaining and pathologist scoring of whole tissue sections or by immunofluorescence and automated quantitative analysis (AQUA) of tissue microarrays. Results Nuc-pYStat5 was an independent prognostic marker as measured by cancer-specific survival (CSS) in patients with node-negative breast cancer who did not receive systemic adjuvant therapy, when adjusted for common pathology parameters in multivariate analyses both by standard chromogen detection with pathologist scoring of whole tissue sections (cohort I; n = 233) and quantitative immunofluorescence of a tissue microarray (cohort II; n = 291). Two distinct monoclonal antibodies gave concordant results. A progression array (cohort III; n = 180) revealed frequent loss of Nuc-pYStat5 in invasive carcinoma compared to normal breast epithelia or ductal carcinoma in situ, and general loss of Nuc-pYStat5 in lymph node metastases. In cohort IV (n = 221), loss of Nuc-pYStat5 was associated with increased risk of antiestrogen therapy failure as measured by univariate CSS and time to recurrence (TTR). More sensitive AQUA quantification of Nuc-pYStat5 in antiestrogen-treated patients (cohort V; n = 97) identified by multivariate analysis patients with low Nuc-pYStat5 at elevated risk for therapy failure (CSS hazard ratio [HR], 21.55; 95% CI, 5.61 to 82.77; P < .001; TTR HR, 7.30; 95% CI, 2.34 to 22.78; P = .001). Conclusion Nuc-pYStat5 is an independent prognostic marker in node-negative breast cancer. If confirmed in prospective studies, Nuc-pYStat5 may become a useful predictive marker of response to adjuvant hormone therapy. PMID:21576635

    Full Text Available The tumour microenvironment consists of malignant cells, stroma, and immune cells. The role of adaptive immunity in inducing a pathological complete response (pCR in breast cancer with neoadjuvant chemotherapy (NAC is well studied. The contribution of innate immunity, however, is poorly documented. Breast tumours and axillary lymph nodes (ALNs from 33 women with large and locally advanced breast cancers (LLABCs undergoing NAC were immunohistochemically assessed for tumour-infiltrating macrophages (TIMs: M1 and M2, neutrophils (TINs, and dendritic cells (TIDCs using labelled antibodies and semiquantitative methods. Patients’ blood neutrophils (n=108, DCs (mDC1 and pDC, and their costimulatory molecules (n=30 were also studied. Pathological results were classified as pCR, good (GPR or poor (PRR. In breast and metastatic ALNs, high levels of CD163+ TIMs were significantly associated with a pCR. In blood, high levels of neutrophils were significantly associated with pCR in metastatic ALNs, whilst the % of mDC1 and pDC and expression of HLA-DR, mDC1 CD40, and CD83 were significantly reduced. NAC significantly reduced tumour DCs but increased blood DCs. PPRs to NAC had significantly reduced HLA-DR, CD40, and CD86 expression. Our study demonstrated novel findings documenting the differential but important contributions of innate immunity to pCRs in patients with LLABCs undergoing NAC.

    Asian women, including Korean, have a relatively higher incidence of dense breast tissue, compared with western women. Dense breast tissue has a lower sensitivity for the detection of breast cancer and a higher relative risk for breast cancer, compared with fatty breast tissue. Thus, there were limitations in the mammographic screening for women with dense breast tissue, and many studies for the supplemental screening methods. This review included appropriate screening methods for Korean women with dense breasts. We also reviewed the application and limitation of supplemental screening methods, including breast ultrasound, digital breast tomosynthesis, and breast magnetic resonance imaging; and furthermore investigated the guidelines, as well as the study results.

  3. Green Tea and Breast Cancer

    Wu, Anna H; Butler, Lesley M

    2014-01-01

    The identification of modifiable lifestyle factors that could reduce the risk of breast cancer is a research priority. Despite the enormous chemo preventive potential of green tea and compelling evidence from animal studies, its role in breast cancer development in humans is still unclear. Part of the uncertainty is related to the relatively small number of epidemiological studies on green tea and breast cancer and that the overall results from case-control studies and prospective cohort studies are discordant. In addition, the mechanisms by which green tea intake may influence risk of breast cancer in humans remains not well studied. We review the human studies that have evaluated the relationship between green tea intake and four biomarkers (sex steroid hormones, mammographic density, insulin-like growth factor, adiponectin) that are believed to be important in breast cancer development. Results from these biomarker studies are also inconclusive. Limitations of human studies and areas of further investigations are discussed. PMID:21538855

    Between 1975 and 1983, sixteen patients with a history of irradiation at an early age to the head, neck, or chest areas for a variety of conditions in whom breast cancer subsequently developed were seen at out institute. The median latent period between the irradiation and the development of breast cancer was 420 months. The distribution of patients by stage of the disease and the median age at diagnosis of this subgroup was similar to the breast cancer observed in the general population. The subsequent course of this disease was also similar to the breast cancer observed in the general population.

  6. Intraoperative Radiotherapy for Breast Cancer

    2017-12-01

    Full Text Available Intraoperative radiotherapy (IORT for early stage breast cancer is a technique for partial breast irradiation. There are several technologies in clinical use to perform breast IORT. Regardless of technique, IORT generally refers to the delivery of a single dose of radiation to the periphery of the tumor bed in the immediate intraoperative time frame, although some protocols have performed IORT as a second procedure. There are two large prospective randomized trials establishing the safety and efficacy of breast IORT in early stage breast cancer patients with sufficient follow-up time on thousands of women. The advantages of IORT for partial breast irradiation include: direct visualization of the target tissue ensuring treatment of the high-risk tissue and eliminating the risk of marginal miss; the use of a single dose coordinated with the necessary surgical excision thereby reducing omission of radiation and the selection of mastectomy for women without access to a radiotherapy facility or unable to undergo several weeks of daily radiation; favorable toxicity profiles; patient convenience and cost savings; radiobiological and tumor microenvironment conditions which lead to enhanced tumor control. The main disadvantage of IORT is the lack of final pathologic information on the tumor size, histology, margins, and nodal status. When unexpected findings on final pathology such as positive margins or positive sentinel nodes predict a higher risk of local or regional recurrence, additional whole breast radiation may be indicated, thereby reducing some of the convenience and low-toxicity advantages of sole IORT. However, IORT as a tumor bed boost has also been studied and appears to be safe with acceptable toxicity. IORT has potential efficacy advantages related to overall survival related to reduced cardiopulmonary radiation doses. It may also be very useful in specific situations, such as prior to oncoplastic reconstruction to improve accuracy of

    Full Text Available Objective: This study presents the long-term results of patients who had breast conserving surgery at our clinic because of breast cancer. Methods: The data of 99 patients, who had breast conserving surgery because of breast cancer between January 2005 and December 2013 at Necmettin Erbakan University, Meram Medical School’s Department of General Surgery, were retrospectively evaluated. The analyses of the study were conducted by the SPSS 21.0 program. Results: The total number of patients was 99 and the mean age was 51.11 ± 9.62 (31-74. The most frequently seen pathology was infiltrative ductal carcinoma and it was detected in 62 (62.6% patients. 88.7% (87 cases of the cases received adjuvant radiotherapy in the post-op period. Following the mean follow-up period of 38.86 ± 23.43 (5-92 months, only one patient passed away. Further, 1 patient underwent surgery again after having local recurrence 70 months later and 3 patients also underwent surgery again upon detecting that they had tumors on the surgical border. Conclusion: After obtaining acceptable oncological results, the fundamental approach in the surgical treatment of breast cancers is to select the method that will have the least negative effect on the patient’s quality of life. At this point, selecting breast conserving surgery over radical surgical methods is an appropriate approach for suitable patients chosen carefully.

    2017-02-01

    Eating disorders such as anorexia nervosa and bulimia nervosa affect overall and reproductive health and may also affect breast cancer risk. We studied the association between self-reported eating disorders and breast cancer risk in a prospective cohort study. In 2003-2009, the Sister Study enrolled women ages 35-74 years who had a sister with breast cancer but had never had it themselves. Using data from 47,813 women, we estimated adjusted HRs and 95% confidence intervals (CI) for the association between eating disorders and invasive breast cancer over a median of 5.4 years of follow-up. Three percent (n = 1,569) of participants reported a history of an eating disorder. Compared with women who never had an eating disorder, women who reported eating disorders in the past had reduced breast cancer risk (HR = 0.62; 95% CI, 0.42-0.92). In this large prospective, observational cohort study, we observed an inverse association between having a history of an eating disorder and invasive breast cancer. Historical eating disorders may be associated with a long-term reduction in breast cancer risk.

    Breast cancer is the leading cause of cancer deaths in Ghanaian women.To describes the characteristics of breast cancer patients attending the Komfo Anokye Teaching Hospital in Kumasi, Ghana.The study was conducted at the Komfo Anokye Teaching Hospital. Between July 1st 2004 and June 30th 2009 patients presenting with breast lumps were assessed by clinical examination, imaging studies and pathological examination. Relevant clinical and pathological were recorded prospectively data on all patients with microscopically proven breast cancer. The cancers were graded according to the modified Bloom-Richardson system. Tissue immunoperoxidase stains for oestrogen, progesterone receptors and c-erb2 oncogene were performed with commercially prepared antigens and reagents.Nineteen thousand four hundred and twenty – three (19,423) patients were seen during the study period. There were 330 (1.7%) patients with histologically proven breast cancer. The mean age was 49.1 years. A palpable breast lump was detected in 248 patients (75.2%). Two hundred and eighty –one patients (85.2%) presented with Stages III and IV , 271 (82.1%) invasive and 230 ( 85.2%) high grade carcinomas. Oestrogen and progesterone receptors were positive in 32 and 9 cases respectively. Her2 protein was positive in 11 cases. In Kumasi, as in other parts of Ghana, breast cancer affects mostly young pre-menopausal who present with advanced disease. The cancers have unfavourable prognostic features and are unlikely to respond to hormonal therapy. (au)

  15. [Prolactin, antipsychotics and breast cancer: is there a connection?].

    Science.gov (United States)

    Sabbe, T; Detraux, J; De Hert, M

    The use of antipsychotics can result in elevated prolactin levels or hyperprolactinemia. An increasing number of studies suggests that prolactin plays a role in mammary carcinogenesis, leading to concerns about a possible relationship between antipsychotics and breast cancer. To provide an overview of recent literature regarding the relationship between prolactin, antipsychotics and breast cancer and an association between schizophrenia and breast cancer. We used PubMed to search for English- or Dutch-language articles concerning breast cancer risk (factors), prolactin, antipsychotics and schizophrenia. Studies have not shown any causal link between antipsychotics and the development of breastcancer. Moreover, antipsychotic medication seems to have no influence on locally produced prolactin - which some experts believe plays a role in the tumor genesis - and certain antipsychotics actually provide protection against breast cancer. There are conflicting reports on the prevalence of breast cancer among patients with schizophrenia. Nevertheless, research has revealed that several well-known risk factors for breast cancer (such as an unhealthy lifestyle) are more prevalent in patients with schizophrenia. There is no conclusive evidence that antipsychotic medication that raises prolactin levels increases the risk of breast cancer. Nevertheless, clinicians should always be cautious about prescribing antipsychotics for breast cancer patients. In our view, clinicians should always treat breast cancer risk factors as efficiently as possible, particularly when attending to patients who have schizophrenia.

    1995-01-01

    Between December 1981 and December 1988, 329 consecutive patients with stage I and II breast cancers who underwent wide excision (n = 261) or quadrantectomy (n = 68) with (n = 303) or without (n = 26) axillary dissection were referred to radiotherapy. Final margins of resection were microscopically free from tumor involvement in all cases. Radiotherapy consisted in 40-45 Gy over 4-4.5 weeks to the breast, with (n = 168) or without (n = 161) regional nodal irradiation of 45-50 Gy over 4.5-5 weeks. A mean booster dose of 15 Gy was delivered to the primary site by iridium-192 implant in 169 patients (group 1) or by electrons in 160 patients (group 2). Twenty-seven percent (n = 88) of patients received tamoxifen for ≥ 2 years. Adjuvant chemotherapy was administered in 22% (n = 71) of patients. Groups 1 and 2 were not strictly comparable. Group 1 patients were significantly younger, had smaller tumors, were treated with cobalt at 5 x 2 Gy per week and axillary dissection was more frequently performed. Group 2 patients were more frequently bifocal and more frequently treated by quadrantectomy and tamoxifen, and irradiation used accelerator photons at 4 x 2.50 Gy per week. No difference in terms of follow-up and survival rates was observed between the two groups. For all patients the 5- and 10-year local breast relapse rates were 6.7% and 11%, respectively. No difference was observed regarding local control either by the electron or the iridium-192 implant boosts. Axillary dissection and age had an impact on the breast cosmetic outcome. Furthermore, the cosmetic results seemed to be poorer in group 1 than in group 2. This may be related to other factors; group 1 patients were treated with telecobalt and axillary dissection was more frequently performed; on the other hand, group 2 patients were treated with accelarator photons

    The evolution and development of opinions on the diagnosis and treatment of breast cancer since Galen to present time is presented. The concept of breast cancer as a local disease has been replaced by the understanding of its systemic character. On this background described are the methods of surgical treatment beginning from early - supraradical, to present -conservative approaches. The ''milestones'' in diagnosis and treatment of breast cancer of the last 40 years are presented. Current methods of breast cancer management include correct diagnosis (clinical examination, mammography, ultrasound, fine needle aspiration biopsy), TNM staging, adequate loco-regional therapy, systemic therapy, rehabilitation, reconstruction and careful follow-up.

    Purpose: The purpose of this study was to determine local-regional recurrence (LRR) risk according to whether postmastectomy radiation therapy (PMRT) was used to treat breast cancer patients with clinical T3N0 disease who received neoadjuvant chemotherapy (NAC) and mastectomy. Methodsand Materials: Clinicopathology data from 162 patients with clinical T3N0 breast cancer who received NAC and underwent mastectomy were retrospectively reviewed. A total of 119 patients received PMRT, and 43 patients did not. The median number of axillary lymph nodes (LNs) dissected was 15. Actuarial rates were calculated using the Kaplan-Meier method and compared using the log-rank test. Results: At a median follow-up of 75 months, 15 of 162 patients developed LRR. For all patients, the 5-year LRR rate was 9% (95% confidence interval [CI], 4%-14%). The 5-year LRR rate for those who received PMRT was 4% (95% CI, 1%-9%) vs. 24% (95% CI, 10%-39%) for those who did not receive PMRT (p <0.001). A significantly higher proportion of irradiated patients had pathology involved LNs and were ≤40 years old. Among patients who had pathology involved LNs, the LRR rate was lower in those who received PMRT (p <0.001). A similar trend was observed for those who did not have pathology involved LN disease. Among nonirradiated patients, the appearance of pathologic LN disease after NAC was the only clinicopathologic factor examined that significantly correlated with the risk of LRR. Conclusions: Breast cancer patients with clinical T3N0 disease treated with NAC and mastectomy but without PMRT had a significant risk of LRR, even when there was no pathologic evidence of LN involvement present after NAC. PMRT was effective in reducing the LRR rate. We suggest PMRT should be considered for patients with clinical T3N0 disease.

    Full Text Available Several of the active compounds in foods, poisons, drugs, and industrial chemicals may, by epigenetic mechanisms, increase or decrease the risk of breast cancers. Enzymes that are involved in DNA methylation and histone modifications have been shown to be altered in several types of breast and other cancers resulting in abnormal patterns of methylation and/or acetylation. Hypermethylation at the CpG islands found in estrogen response element (ERE promoters occurs in conjunction with ligand-bonded alpha subunit estrogen receptor (Erα dimers wherein the ligand ERα dimer complex acts as a transcription factor and binds to the ERE promoter. Ligands could be 17-β-estradiol (E2, phytoestrogens, heterocyclic amines, and many other identified food additives and heavy metals. The dimer recruits DNA methyltransferases which catalyze the transfer of methyl groups from S-adenosyl-L-methionine (SAM to 5′-cytosine on CpG islands. Other enzymes are recruited to the region by ligand-ERα dimers which activate DNA demethylases to act simultaneously to increase gene expression of protooncogenes and growth-promoting genes. Ligand-ERα dimers also recruit histone acetyltransferase to the ERE promoter region. Histone demethylases such as JMJD2B and histone methyltransferases are enzymes which demethylate lysine residues on histones H3 and/or H4. This makes the chromatin accessible for transcription factors and enzymes.

Nonetheless, the small number of studies done in middle to low income countries where variability of food intake is wider,is beginning to show interesting results.Tanto la dieta como la nutrición han sido estudiadas en relación con el riesgo de cáncer de mama, dada la gran variación de incidencia de cáncer entre países, y la posibilidad de explicarla a través de la respuesta inflamatoria o inmune, así como ingesta de antioxidantes,entre otros.Hasta la fecha, ninguna asociación clara con la dieta ha sido encontrada, excepto para el consumo de alcohol, más allá del sobrepeso y del incremento de peso.

    The prolonged exposure to estrogen increases the risk of cancer breast, the precise role of estrogen in the carcinogenesis process is unclear. They are capable of inducing cell proliferation through different channels receptor Estrogen (ER) known, for example through MAPkinasa sensitivity the promoter of proliferation effect depends on the level of RE, or type to â, integrity (mutations may alter its function) and ligand. The different types of estrogens and related compounds have different profile of affinity for RE and effect end. The modulatory role of progestogens proliferation is very complex, and the interaction between the effector pathways of progestin’s, estrogens, EGF and IGF family - maybe others - determines the final effect .. Estrogens are mutagenic per se weak, but is now known for its hepatic metabolism occur highly reactive species such as quinones, and catechol, powerful mutagens in vitro. Direct or indirect genotoxicity probably explains Part of the effects of estrogen on tumor cells. The use of hormone replacement (HTR) increases the risk of CM, as proportional to the time of use. The combination with progestin seems to be increased risk (R R 2). It is unclear the role of phyto estrogens in the prevention the CM. In the male breast is known that the proliferative response to parenchymal different hormonal maneuvers is different. The effect is minimal castration are and maximum with the combination of estrogen and progesterone. It is unclear, however, the risk of the population exposed to hormone therapy for cancer prostate or otherwise

    In current treatment of breast cancer, radiotherapy (RT) plays an important role. It can take place in 3 main situations: after mastectomy, after surgical conservative treatment for infiltrating cancer, and after local excision for intraductal cancer. RT plays a particularly important role in conservative treatment of small breast cancer; the relevance of a boost after 50 Gy will be elucidated in the coming years by the ongoing random trials. More and more the indication of this boost will be individualized according to parameters predicting for the risk of local relapse (age, extensive intraductal carcinoma, or free margin). After mastectomy the benefit interns of survival remains controversial. In large T2 T3 tumors, still often treated by mastectomy, neoadjuvant chemo-, and radiotherapy, should be able to reduce the number of mutilating surgery. (author). 7 refs

    Purpose Data on international variation in breast cancer incidence may help to identify additional risk factors. Substantially lower breast cancer rates in Asia than in North America and Western Europe are established, but differences within Asia have been largely ignored despite heterogeneity in lifestyles and environments. Mongolia’s breast cancer experience is of interest because of its shared genetics but vastly different diet compared with other parts of Asia. Methods Age-standardized breast cancer incidence and mortality rates obtained from the International Association of Cancer Registries are presented for several Asian countries. Mongolian incidence rates obtained from its cancer registry describe incidence within the country. Results Breast cancer incidence in Mongolia (age standardized 8.0/100,000) is almost a third of rates in China (21.6/100,000), and over five times that of Japan (42.7/100,000) and Russia (43.2/100,000). Rates within Mongolia appear to have increased slightly over the last decade and are higher in urban than rural areas (annual percentage increase of age-standardized rates from 1998 to 2005 was 3.60 and 2.57%, respectively). The increase in breast cancer incidence with age plateaus at menopause, as in other Asian populations. Conclusions Mongolia’s low breast cancer incidence is of particular interest because of their unusual diet (primarily red meat and dairy) compared with other Asian countries. More intensive study of potential dietary, reproductive and lifestyle factors in Mongolia with comparison to other Asian populations may provide more clarity in what drives the international breast cancer rate differences.

    Surgical therapy for occult breast cancer has traditionally centered on mastectomy; however, breast conservation with whole breast radiotherapy followed by axillary lymph node dissection has shown equivalent results. Patients with breast cancer in pregnancy can be safely and effectively treated; given a patient's pregnancy trimester and stage of breast cancer, a clinician must be able to guide therapy accordingly. Male breast cancer risk factors show strong association with BRCA2 mutations, as well as Klinefelter syndrome. Several retrospective trials of surgical therapy in stage IV breast cancer have associated a survival advantage with primary site tumor extirpation. Copyright © 2013 Elsevier Inc.

    In the background of the current situation of breast cancer in Pakistan, with its rising incidence and mortality, non afford ability and inaccessibility to screening, diagnosis and treatment, Patel Hospital took up the task of addressing these issues at a local level, by initiating an annual free breast camp in the year 2006. In 2008 an inclusion criteria was defined to focus on high risk women for breast cancer. A comparative analysis over a period of three years was done. In the focused camps, in which 28% patients were found to have a positive family history. Most women were symptomatic. Total 11 patients were diagnosed to have cancer after evaluation. Six patients underwent definitive treatment. A problem with lack of awareness, regarding screening and treatment protocols was identified. Family history seems to be an important risk factor in our set up signifying the need to introduce extensive screening programmes. (author)

    Deep inspiration breath hold (DIBH) in left-sided breast cancer radiotherapy is a technique to reduce cardiac and pulmonary doses while maintaining target coverage. This study aims at evaluating an in-house developed DIBH system. Free-breathing (FB) and DIBH plans were generated for 22 left-sided localized breast cancer patients who had radiation therapy (RT) after breast-conserving surgery. All patients were treated utilizing an in-house laser distance measuring system. 50 Gy was prescribed, and parameters of interest were target coverage, left anterior descending coronary artery, (LAD) and heart doses. Portal images were acquired and the reproducibility and stability of DIBH treatment were compared to FB. The comparing result shows there is a significant reduction in all LAD and heart dose statistics for DIBH compared to FB plans without compromising the target coverage. The maximum LAD dose was reduced from 43.7 Gy to 29.0 Gy and the volume of the heart receiving >25 Gy was reduced from 3.3% to 1.0% using the in-house system, both statistically significant. The in-house system gave a reproducible and stable DIBH treatment where the systematic error ∑, and random error σ, were less than 2.2 mm in all directions, but were not significantly better than at FB. The system was well tolerated and all patients completed their treatment sessions with DIBH. © 2017 The Authors.

    Response evaluation following neo-adjuvant chemotherapy in breast cancer is usually done without taking in to account the axillary response and the available tools like 'response evaluation criteria in solid tumors' (RECIST) have this limitation. These criteria rely solely on the response observed in the primary tumour. Neoadjuvant response index is one such attempt to have a comprehensive assessment of response both in the primary tumour and the axilla. 30 cases of locally advanced breast cancer (LABC) were assessed for response using 'Neo-adjuvant Response Index'. The index always gives score between '0' (no response or progressive disease) and '1' (pathological complete response i.e. no invasive tumor in breast as well as axilla). This index includes axillary response as well and provides a spectrum of response rather than dividing patients into simply responders and non-responders . Mean reading of index was found to be 0.2925 in this study. Three patients achieved an index of 1. This index correlates significantly with the existing scales for assessing response. Hormone negative tumors were found to be more chemo responsive with higher rates of pathological complete response (pCR) while ER/PR + Her2- tumors showed a very poor response to NACT. Based on the observations of the present study it may be submitted that Neoadjuvant Response Index (NRI) is a reliable and simple tool that can serve as a comprehensive and accurate method of assessing response to neo-adjuvant chemotherapy as it takes in to consideration both the tumor and axillary response unlike the existing RECIST, binary system (responders are those with greater than 50 % reduction), RCB method and the available biomarkers. This study being first of it's kind in Indian population, in spite of it's limitations, could prove to be a launching ground for further reasearch and contribute substantially to the evidence base.

    In the last two decades, molecular studies have enlightened the complexity of the genetic alterations that occur in breast cancer cells. To date, more than 40 different genes or loci have been found to be altered in breast carcinomas. Although some of these genes, as for example ERBB2, appear to be mutated in a high proportion of cases, their mechanism of action and their role in the different stages of cancer development are still poorly understood. More recently, two major determinants of the inherited predisposition to breast cancer, BRCA1 and BRCA2, have been isolated. As a consequence, it is now possible to screen families with a positive history of breast carcinomas for the identification of mutations carriers, in order to address these individuals into adequate programs of cancer surveillance and prevention.

  13. Does Aluminium Trigger Breast Cancer?

    Directory of Open Access Journals (Sweden)

    Peter Jennrich

    2016-08-01

    Full Text Available Summary. Breast cancer is by far the most common cancer in women in the western world. In 90% of breast cancers, environmental factors are among the causes. The frequency with which the tumour occurs in the outer upper part of the breast has risen with above average rates in recent decades. Aluminium salts as ingredients in deodorants and antiperspirants are being absorbed by the body to a greater extent than hitherto assumed. Their toxicity for healthy and diseased breast tissue cells includes various well-documented pathomechanisms. In the sense of primary and secondary prevention, the cancer-triggering potential of aluminium and its use in anti-perspirant deodorants must be re-evaluated. For the same reason the access to a targeted diagnosis and treatment of aluminium loading must be facilitated.

    Patients with hereditary breast cancer (BC) may benefit from genetic counseling and testing for detection of causative mutations, definition of therapeutic and preventive strategies, and identification of at-risk relatives. Italy has few oncogenetic centers and genetic evaluation of all patients with BC is not feasible. Moreover, lack of uniformity in the selection of patients generates inappropriate referral to the geneticist. We designed a model that may represent a reproducible way to select patients at risk for hereditary BC, with the aims of rationalizing access to genetic centers and improving clinical management and surveillance. The genetic unit of a Cancer Center and the Departments of Oncology from 2 public Hospitals in Milan were involved in the project. After training sessions at the genetic unit, operators from the 2 hospitals evaluated all patients with BC attending a first oncologic visit, through a specific interview. Patients considered at risk of hereditary BC attended counseling at the genetic unit. Of 419 patients, 61 (14.5%) were eligible for genetic counseling after the interview. Of these, 46 (10.9%) strictly met testing criteria. Overall, 52 (12.4%) patients underwent genetic counseling and 47 were tested for BRCA1/BRCA2 mutation. After genetic test results, the available options for treatment/surveillance were discussed by a multidisciplinary team, according to the level of genetic risk. It is possible to improve the process of referring patients with suspected hereditary BC for genetic risk assessment. The application of clinical screening reduced the genetics unit's workload and enabled optimization of time and resources.

  18. Iodide transport and breast cancer.

    Poole, Vikki L; McCabe, Christopher J

    2015-10-01

    Breast cancer is the second most common cancer worldwide and the leading cause of cancer death in women, with incidence rates that continue to rise. The heterogeneity of the disease makes breast cancer exceptionally difficult to treat, particularly for those patients with triple-negative disease. To address the therapeutic complexity of these tumours, new strategies for diagnosis and treatment are urgently required. The ability of lactating and malignant breast cells to uptake and transport iodide has led to the hypothesis that radioiodide therapy could be a potentially viable treatment for many breast cancer patients. Understanding how iodide is transported, and the factors regulating the expression and function of the proteins responsible for iodide transport, is critical for translating this hypothesis into reality. This review covers the three known iodide transporters - the sodium iodide symporter, pendrin and the sodium-coupled monocarboxylate transporter - and their role in iodide transport in breast cells, along with efforts to manipulate them to increase the potential for radioiodide therapy as a treatment for breast cancer. © 2015 Society for Endocrinology.

    To assess bilateral breast cancer patients, initially diagnosed with stage II unilateral breast cancer. 113 patients with stage 0-II breast cancer diagnosed between 1983 and 2011 were assessed. Of these, 8 patients had bilateral breast cancer: 7 patients with metachronous bilateral breast cancer and 1 patient with synchronous breast cancer. Breast ultrasound, mammography, computed tomography and magnetic resonance imaging were used to diagnose recurrence, loco regional and distant metastasis. Age at diagnosis ranged from 37 to 59 years, with a maximum age incidence in the 4th decade (age between: 31-40 years). The average time interval between the two breast cancers was 8.125 years. The most common histological type was invasive ductal carcinoma. All eight patients with bilateral breast cancer had at least one type of recurrence/metastasis, mostly in the liver, and statistically the pleuropulmonary and liver metastases were the most frequent causes of death. Patients in the 4th decade diagnosed with unilateral breast cancer are at risk of developing bilateral breast cancer. In metachronous breast cancer, the time interval between the detection of the second breast cancer and death is directly proportional to the time interval between the two breast cancers.

    This study aimed to assess the diagnostic performance of integrated positron emission tomography (PET)/magnetic resonance imaging (MRI) of the breast for lesion detection and local tumor staging of patients with primary breast cancer in comparison to PET/computed tomography (CT) and MRI. The study was approved by the local institutional review board. Forty-nine patients with biopsy-proven invasive breast cancer were prospectively enrolled in our study. All patients underwent a PET/CT, and subsequently, a contrast-enhanced PET/MRI of the breast after written informed consent was obtained before each examination. Two radiologists independently evaluated the corresponding data sets (PET/CT, PET/MRI, and MRI) and were instructed to identify primary tumors lesions as well as multifocal/multicentric and bilateral disease. Furthermore, the occurrence of lymph node metastases was assessed, and the T-stage for each patient was determined. Histopathological verification of the local tumor extent and the axillary lymph node status was available for 30 of 49 and 48 of 49 patients, respectively. For the remaining patients, a consensus characterization was performed for the determination of the T-stage and nodal status, taking into account the results of clinical staging, PET/CT, and PET/MRI examinations. Statistical analysis was performed to test for differences in diagnostic performance between the different imaging procedures. P values less than 0.05 were considered to be statistically significant. Positron emission tomography/MRI and MRI correctly identified 47 (96%) of the 49 patients with primary breast cancer, whereas PET/CT enabled detection of 46 (94%) of 49 breast cancer patients and missed a synchronous carcinoma in the contralateral breast in 1 patient. In a lesion-by-lesion analysis, no significant differences could be obtained between the 3 imaging procedures for the identification of primary breast cancer lesions (P > 0.05).

    Conventionally, breast cancer diagnosed during pregnancy and within the years following have been referred to collectively as pregnancy-associated breast cancer. However, increasing evidence suggests that breast cancer diagnosed during pregnancy is a different entity from that diagnosed postpartum, both in terms of prognosis and biology. Given the increasing number of women who find themselves diagnosed with breast cancer during or following a pregnancy, future research and discussion should separate these two into distinct groups: breast cancer diagnosed during pregnancy and breast cancer diagnosed postpartum in an effort to enhance our understanding to inform and improve clinical management and counseling.

    The ATM protein is activated as a result of ionizing radiation, and genetic variants of the ATM gene may therefore affect the level of radiation-induced damage. Individuals heterozygous for ATM mutations have been reported to have an increased risk of malignancy, especially breast cancer. Norwegian breast cancer patients (272) treated with radiation (252 of which were evaluated for radiation-induced adverse side effects), 95 Norwegian women with no known history of cancer and 95 American breast cancer patients treated with radiation (44 of which developed ipsilateral breast tumour recurrence, IBTR) were screened for sequence variations in all exons of the ATM gene as well as known intronic variants by denaturating high performance liquid chromatography (dHPLC) followed by sequencing to determine the nature of the variant. A total of 56 variants were identified in the three materials combined. A borderline significant association with breast cancer risk was found for the 1229 T>C (Val>Ala) substitution in exon 11 (P-value 0.055) between the Norwegian controls and breast cancer patients as well as a borderline significant difference in haplotype distribution (P-value 0.06). Adverse side effects, such as: development of costal fractures and telangiectasias, subcutaneous and lung fibrosis, pleural thickening and atrophy were evaluated in the Norwegian patients. Significant associations were found for several of the identified variants such as rs1800058 (Leu > Phe) where a decrease in minor allele frequency was found with increasing level of adverse side effects for the clinical end-points pleural thickening and lung fibrosis, thus giving a protective effect. Overall our results indicate a role for variation in the ATM gene both for risk of developing breast cancer, and in radiation induced adverse side effects. No association could be found between risk of developing ipsilateral breast tumour recurrence and any of the sequence variants found in the American patient

    Histological and immunohistochemical examination of the tissue from 45 breast cancer patients after surgery (14) and combined treatment (31) Was performed. Using direct Coons method the localization of immune complexes and immunoglobulins of the main classes (G, A, M) was revealed. Deposits of immune complexes including immunoglobulins of different classes were found in 8 patients of the 1st group and 22 patients of the 2 nd group. Immune complexes were mostly localized extracellularly in the stroma. After irradiation extensive deposit and more intense fluorescence of immune complexes in the stroma of a tumor, lumps in the walls of the major vessels were observed. It is assumed that immune complexes and immunoglobulins of different classes related to breast cancer epithelial cells, block the immunological interaction of T lymphocytes with cancer cells were carried out. The suppression effect of radiotherapy on tumor cell receptor activity has been shown that is not only of theoretical but also of practical interest

    Purpose: American College of Surgeons Oncology Group Z1071 was a prospective trial evaluating the false negative rate of sentinel lymph node (SLN) surgery after neoadjuvant chemotherapy (NAC) in breast cancer patients with initial node-positive disease. Radiation therapy (RT) decisions were made at the discretion of treating physicians, providing an opportunity to evaluate variability in practice patterns following NAC. Methods and Materials: Of 756 patients enrolled from July 2009 to June 2011, 685 met all eligibility requirements. Surgical approach, RT, and radiation field design were analyzed based on presenting clinical and pathologic factors. Results: Of 401 node-positive patients, mastectomy was performed in 148 (36.9%), mastectomy with immediate reconstruction in 107 (26.7%), and breast-conserving surgery (BCS) in 146 patients (36.4%). Of the 284 pathologically node-negative patients, mastectomy was performed in 84 (29.6%), mastectomy with immediate reconstruction in 69 (24.3%), and BCS in 131 patients (46.1%). Bilateral mastectomy rates were higher in women undergoing reconstruction than in those without (66.5% vs 32.2%, respectively, P<.0001). Use of internal mammary RT was low (7.8%-11.2%) and did not differ between surgical approaches. Supraclavicular RT rate ranged from 46.6% to 52.2% and did not differ between surgical approaches but was omitted in 193 or 408 node-positive patients (47.3%). Rate of axillary RT was more frequent in patients who remained node-positive (P=.002). However, 22% of patients who converted to node-negative still received axillary RT. Post-mastectomy RT was more frequently omitted after reconstruction than mastectomy (23.9% vs 12.1%, respectively, P=.002) and was omitted in 19 of 107 patients (17.8%) with residual node-positive disease in the reconstruction group. Conclusions: Most clinically node-positive patients treated with NAC undergoing mastectomy receive RT. RT is less common in patients undergoing reconstruction. There

    Purpose: American College of Surgeons Oncology Group Z1071 was a prospective trial evaluating the false negative rate of sentinel lymph node (SLN) surgery after neoadjuvant chemotherapy (NAC) in breast cancer patients with initial node-positive disease. Radiation therapy (RT) decisions were made at the discretion of treating physicians, providing an opportunity to evaluate variability in practice patterns following NAC. Methods and Materials: Of 756 patients enrolled from July 2009 to June 2011, 685 met all eligibility requirements. Surgical approach, RT, and radiation field design were analyzed based on presenting clinical and pathologic factors. Results: Of 401 node-positive patients, mastectomy was performed in 148 (36.9%), mastectomy with immediate reconstruction in 107 (26.7%), and breast-conserving surgery (BCS) in 146 patients (36.4%). Of the 284 pathologically node-negative patients, mastectomy was performed in 84 (29.6%), mastectomy with immediate reconstruction in 69 (24.3%), and BCS in 131 patients (46.1%). Bilateral mastectomy rates were higher in women undergoing reconstruction than in those without (66.5% vs 32.2%, respectively, P<.0001). Use of internal mammary RT was low (7.8%-11.2%) and did not differ between surgical approaches. Supraclavicular RT rate ranged from 46.6% to 52.2% and did not differ between surgical approaches but was omitted in 193 or 408 node-positive patients (47.3%). Rate of axillary RT was more frequent in patients who remained node-positive (P=.002). However, 22% of patients who converted to node-negative still received axillary RT. Post-mastectomy RT was more frequently omitted after reconstruction than mastectomy (23.9% vs 12.1%, respectively, P=.002) and was omitted in 19 of 107 patients (17.8%) with residual node-positive disease in the reconstruction group. Conclusions: Most clinically node-positive patients treated with NAC undergoing mastectomy receive RT. RT is less common in patients undergoing reconstruction. There

    The rising incidence of breast cancer is complicated by late presentation, which marks breast cancer diagnosis in Nigeria with about 70% of cases presenting at advanced stages of the disease. The aim of this study is to determine the general level of awareness of breast cancer, breast cancer risk factors, signs/symptoms as well as preventive measures nothern Nigerian women. It also aimed at determining their attitudes toward breast cancer cure, prevention and cause. Finally, it aims to determine their practices toward breast cancer and its associated factors. A cross-sectional community survey was used to study 230 women aged 15-60 years in Chikun Local Government Area. The subjects were selected based on nonprobability sampling. Data collected using self-administered questionnaire were analyzed using Statistical Package for Social Science students (version 16). Test of associations employed Chi-square statistical tool with the level of significance taken at 0.05. About 75.2% knew about breast cancer with health facility (29.13%) being the greatest source of information. An average of 29.35% had knowledge of the risk factors tested. Mean knowledge of the signs and symptoms was 50.1% Average knowledge of breast cancer screening methods was 34.26% with breast self-examination (BSE) (46.1%) being the most recognized. In relation to perception, about 21.7% strongly agreed with the fact that breast cancer is treatable following early detection while 18.3% strongly agreed that screening is effective in detecting breast cancer. Concerning practice, an average of 10.2% practiced any of the screening methods, with BSE (17.4%) being the most practiced. Strongest reasons for nonpractice was ignorance (17.4%). An association was established between knowledge and practice of all the screening methods (P = 0.001 respectively). There is insufficient knowledge, as well as poor practices in relation to important factors associated with breast cancer prevalence.

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    Full Text Available Background: Metaplastic carcinoma of the breast is an extremely rare subtype of breast cancer with an incidence of <1% of all breast neoplasms. Metaplastic carcinoma with chondroid differentiation is the rarest among all histologic subtypes of breast cancer. We report a case of infiltrating ductal carcinoma with metaplastic features of chondroid differentiation. Case presentation: A 58-year-old-woman presented to our clinic with a 4-month history of a lump in her right breast. On examination, a firm non-tender mass measuring 2×2 cm was noted in the right upper outer quadrant. It was not attached to the underlying structures. Mammography revealed a dense irregular mass in the axillary tail and a circumscribed nodule in the 6 O'clock periareolar region. This was a new development compared to the patient's most recent screening mammogram performed 2 years and 6 months previously. Ultrasound demonstrated a lobulated solid mass in the axillary tail and a simple cyst in the 6 O'clock periareolar region. Biopsy of the areolar region of the right breast revealed atypical duct hyperplasia. Fine needle aspiration cytology of the right breast axillary tail revealed a poorly differentiated invasive carcinoma consistent with mammary duct origin. On histopathological examination, it was an infiltrating ductal carcinoma with metaplastic features of chondroid differentiation. The tumor was estrogen receptor, progesterone receptor, and HER-2 negative with 0% nuclear staining. Ki-67 index was 52% with strong nuclear staining. The overall ELSTON grade of invasive carcinoma was grade 3. The patient received adjuvant chemotherapy with AC-T (adriamycin, cytoxan, and taxol and is currently undergoing surveillance for recurrent disease. Conclusion: Metaplastic breast cancer is an extremely rare subtype of breast carcinoma. Initial management of localized disease consists of wide excision with clear surgical margins followed by radiation or mastectomy and sentinel

    An increase in the incidence of breast cancer in women aged breast cancer in women of childbearing age has significantly improved, they are often concerned whether subsequent pregnancy will alter their risk of disease recurrence. In the modern era, the prognosis of pregnancy-associated breast cancer is comparable to non-pregnancy-associated breast cancer and women can bear children after breast cancer treatment without compromising their survival. Therefore, they should not be discouraged from becoming pregnant, and currently the usual waiting time of at least 2 years after the diagnosis of breast cancer is recommended. However, a small, nonsignificant adverse effect of pregnancy on breast carcinoma prognosis among women who conceive within 12 months of breast cancer diagnosis and a higher risk of relapse in women younger than 35 up to 5 years of the diagnosis may be found. Fortunately, for women with localized disease, earlier conception up to six months after completing their treatment seems unlikely to reduce their survival. Ongoing and future prospective studies evaluating the risks associated with pregnancy in young breast cancer survivors are required.

    To evaluate fine needle localized biopsy under mammography-guiding and skin incision selection by hookwire under ultrasound-guiding for patients with breast microcalcification. Breast microcalcification of 178 patients treated from May 2000 to November 2006 were resected after localized with fine needle under X-ray mammography-guiding. Among them, 62 patients received the selection of hookwire under ultrasound-guiding. Breast cancer was detected in 58 patients (32.6%). Among them, 32 (55.1%) cases were carcinoma in situ, 11 (19.0%) intraductal carcinoma with early infiltration, 15 (25.9%) infiltrative ductal carcinoma, and 4 infiltrative ductal carcinoma with lymph node metastasis. The overall 5-year survival rate was 100%. Compared with that in needle guided group, the acceptable rate of cosmetic results was higher in hookwire group (P = 0.022). For breast microcalcification, mammography guided needle biopsy with ultrasound selected skin incision is an effective and accurate diagnostic method.

    Full Text Available Trastuzumab emtansina (T-DM1 is an antibody-drug conjugate directed against the HER2 for the treatment of HER2+ mestastatic breast cancer (MBC, who has previously received trastuzumab plus a taxane. According to the results of the EMILIA trial versus lapatinib plus capecitabine T-DM1 shows an improvement in progression-free survival (PFS and the overall survival (OS. It has a favorable profile reducing the incidence of grade 3-4 adverse reactions such as hand-foot syndrome and diarrhea. On the contrary increases significantly severe thrombocytopenia; bleeding risk and liver function should also be monitored. With the current import price T-DM1 has a cost per QALY of over 120,000 €. The price of the drug for the Spanish NHS has not yet been established. Drug cost would be the key factor in the sensitivity analysis and a 50% reduction in the price of the drug would place it close to the threshold of cost-effectiveness usually considered in our midst. According to the budget impact model used, a maximum of 1,218 patients / year and the budgetary impact throughout the Spanish state would be at € 70,490,850. In the initial analysis no advantage was found for T-DM1 in those patients without visceral involvement. Although a subsequent re-analysis of the results of PFS in which the definition of visceral involvement was specified a significant benefit was shown in this subgroup. We believe that this approach introduces a high degree of uncertainty, which does not guarantee the benefit achieved for this subgroup of patients

    The objective of this study was to examine the mammographic breast density of women with breast cancer detected on voluntary mammographic screening at two selected screening centers in Malaysia. This was a retrospective study of Full-Field Digital Mammography (FFDM) images of 150 Malaysian women with biopsy-proven breast cancer. The study population comprised 73 Malays (37.7 %), 59 Chinese (39.3 %) and 18 Indians (12.0 %). The Tabar breast density Patterns (I - V) were used to evaluate mammographic breast density. Data were analyzed using descriptive statistics. The results were compared with findings from a similar study on a group of 668 women who did not have breast cancer. The results showed that 44.7 % of the study population had dense breasts (Patterns IV and V), 14.7 % had predominantly fatty breasts (Patterns II and III) while 40.7 % had Pattern I. The proportion of study population with dense breasts decreased with age. In conclusion, the proportion of women with dense breasts decreased with age. Majority of the women with cancer (44.7 %) had dense breasts of Tabar Patterns IV and V, which has been associated with increased risk of breast cancer detected by voluntary mammographic screening. The results support the notion that increased breast density is a risk factor of breast cancer. (author)

  2. AR Signaling in Breast Cancer

    Directory of Open Access Journals (Sweden)

    2017-02-01

    Full Text Available Androgen receptor (AR, a member of the steroid hormone receptor family status has become increasingly important as both a prognostic marker and potential therapeutic target in breast cancer. AR is expressed in up to 90% of estrogen receptor (ER positive breast cancer, and to a lesser degree, human epidermal growth factor 2 (HER2 amplified tumors. In the former, AR signaling has been correlated with a better prognosis given its inhibitory activity in estrogen dependent disease, though conversely has also been shown to increase resistance to anti-estrogen therapies such as tamoxifen. AR blockade can mitigate this resistance, and thus serves as a potential target in ER-positive breast cancer. In HER2 amplified breast cancer, studies are somewhat conflicting, though most show either no effect or are associated with poorer survival. Much of the available data on AR signaling is in triple-negative breast cancer (TNBC, which is an aggressive disease with inferior outcomes comparative to other breast cancer subtypes. At present, there are no approved targeted therapies in TNBC, making study of the AR signaling pathway compelling. Gene expression profiling studies have also identified a luminal androgen receptor (LAR subtype that is dependent on AR signaling in TNBC. Regardless, there seems to be an association between AR expression and improved outcomes in TNBC. Despite lower pathologic complete response (pCR rates with neoadjuvant therapy, patients with AR-expressing TNBC have been shown to have a better prognosis than those that are AR-negative. Clinical studies targeting AR have shown somewhat promising results. In this paper we review the literature on the biology of AR in breast cancer and its prognostic and predictive roles. We also present our thoughts on therapeutic strategies.

    Background and purpose: The aim of the present paper is to update the practical guidelines for postoperative adjuvant radiotherapy of breast cancer published in 2007 by the breast cancer expert panel of the German Society for Radiooncology (Deutsche Gesellschaft fuer Radioonkologie, DEGRO). The present recommendations are based on a revision of the German interdisciplinary S-3 guidelines published in July 2012. Methods: A comprehensive survey of the literature concerning radiotherapy following breast conserving therapy (BCT) was performed using the search terms 'breast cancer', 'radiotherapy', and 'breast conserving therapy'. Data from lately published meta-analyses, recent randomized trials, and guidelines of international breast cancer societies, yielding new aspects compared to 2007, provided the basis for defining recommendations according to the criteria of evidence-based medicine. In addition to the more general statements of the DKG (Deutsche Krebsgesellschaft), this paper addresses indications, target definition, dosage, and technique of radiotherapy of the breast after conservative surgery for invasive breast cancer. Results: Among numerous reports on the effect of radiotherapy during BCT published since the last recommendations, the recent EBCTCG report builds the largest meta-analysis so far available. In a 15 year follow-up on 10,801 patients, whole breast irradiation (WBI) halves the average annual rate of disease recurrence (RR 0.52, 0.48-0.56) and reduces the annual breast cancer death rate by about one sixth (RR 0.82, 0.75-0.90), with a similar proportional, but different absolute benefit in prognostic subgroups (EBCTCG 2011). Furthermore, there is growing evidence that risk-adapted dose augmentation strategies to the tumor bed as well as the implementation of high precision RT techniques (e.g., intraoperative radiotherapy) contribute substantially to a further reduction of local relapse rates. A main focus of ongoing research lies in partial breast

    2012-08-01

    Many drug delivery systems (DDSs) have been investigated for local targeting of malignant disease with the intention of increasing anti-tumor activity and minimizing systemic toxicity. An injectable thermosensitive hydrogel was applied to prevent locoregional recurrence of 4T1 breast cancer in a mouse model. The presented hydrogel, which is based on poly(ethyleneglycol)-poly(ε-caprolactone)-poly(ethylene glycol) (PEG-PCL-PEG, PECE), flows freely at normal temperature, forms a gel within seconds in situ at body temperature, and eventually releases the drug in a consistent and sustained fashion as it gradually biodegrades. Locoregional recurrence after primary tumor removal was significantly inhibited in mice treated with the paclitaxel (PTX)-loaded PECE hydrogel subcutaneously (9.1%) administered, compared with the blank hydrogel (80.0%), systemic (77.8%) and locally (75.0%) administered PTX, and the control group (100%) (P 0.05), in agreement with histopathological examinations. This novel DDSs represents a promising approach for local adjuvant therapy in malignant disease.

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

    Skowronek, J.

    2007-01-01

    Breast conserving surgery (BCS) and radiotherapy (EBRT) of the conserved breast became widely accepted in the last decades for the treatment of early invasive breast cancer. The standard technique of RT after breast conservation is to treat the whole breast up to a total dose of 45 to 50 Gy. Initially brachytherapy for breast cancer was used in addition of external radiation to boost a portion of the breast to higher doses. However, over the past 10 years, the application of brachytherapy in breast cancer has changed. In early stage breast cancer, research has shown that the area that requires radiation treatment to prevent the cancer from returning is the breast tissue that surrounds the area where the initial cancer was removed. Because this typically includes only a part of the breast, brachytherapy is now being used to treat the targeted portion of the breast and as a result allows accelerated delivery of the radiation dose so that treatment is completed in four to five days. Another indications for PDR - BT as a part of treatment in locally advanced breast cancer or as a palliative treatment are discussed in the paper, too. Preliminary results with PDR - BT boost technique are promising. However, more experience and longer follow-up are required to define whether these methods might improve local tumor control for breast cancer patients. In this article the current status, indications, technical aspects and published results of PDR brachytherapy (PDR - BT) in breast cancer treatment are reviewed. (author)

  13. Insulin growth factor-1 receptor (IGF-1R) expression as a prognostic indicator of local recurrence in conservatively treated breast cancer: a case-control study

    Purpose: The IGF-1R is a glycoprotein receptor that consists of a heterodimer of two alpha and two beta subunits which are processed from a single precursor transmembrane polypeptide and has been found to be overexpressed in a variety of tumors. IGF-1R has been shown to play a critical role in malignant transformation and to influence apoptosis. We have recently shown in gene transfer studies that overexpression of the IGF-1R confers relative radioresistance on mouse fibroblasts in culture. To test the significance of this finding in a clinical setting, we have sought to determine the prognostic significance of overexpression of IGF-1R with respect to ipsilateral breast tumor recurrence (IBTR) in the conservatively treated breast cancer patient. Materials and Methods: Over 1,000 breast cancer patients treated with conservative surgery followed by radiation therapy to the intact breast served as the patient population for this study. Twenty-five patients with a diagnosis of invasive ductal carcinoma who had an IBTR as the first site of failure comprised the index case population base of this study. Following the identification of 25 patients with IBTR, the breast database was searched for 25 matching control patients who did not have an IBTR. The control patients were matched to the index case with respect to age (within 5 years), menopausal status, approximate date of radiation therapy, primary histology, axillary dissection, nodal status, primary tumor size, estrogen/progesterone receptor (ER/PR) status, and adjuvant chemotherapy/hormonal therapy. Both index cases and the matched control group received radiation therapy to a total dose of 64 Gy to the tumor bed. Following identification of index and control cases, the individual paraffin-embedded blocks (PEB) were evaluated for invasive ductal carcinoma with H and E staining by the pathologist. All PEB were then processed for immunohistochemical staining with a polyclonal antibody to the beta-chain of IGF-1R

    Full Text Available Abstract Background Male breast cancer is a rare but aggressive and devastating disease. This disease presents at a later stage and in a more advanced fashion than its female counterpart. The immunophenotype also appears to be distinct when compared to female breast cancer. Angiogenesis plays a permissive role in the development of a solid tumor and provides an avenue for nutrient exchange and waste removal. Recent scrutiny of angiogenesis in female breast cancer has shown it to be of significant prognostic value. It was hypothesized that this holds true in invasive ductal carcinoma of the male breast. In the context of male breast cancer, we investigated the relationship of survival and other clinico-pathological variables to the microvascular density of the tumor tissue. Methods Seventy-five cases of primary male breast cancer were identified using the records of the Saskatchewan Cancer Agency over a period of 26 years. Forty-seven cases of invasive ductal carcinoma of the male breast had formalin-fixed paraffin-embedded tissue blocks that were suitable for this study. All cases were reviewed. Immunohistochemical staining was performed for the angiogenic markers (cluster designations 31 (CD31, 34 (CD34 and 105 (CD105, von Willebrand factor (VWF, and vascular endothelial growth factor (VEGF. Microvascular density (MVD was determined using average, centre, and highest microvessel counts (AMC, CMC, and HMC, respectively. Statistical analyses compared differences in the distribution of survival times and times to relapse between levels of MVD, tumor size, node status and age at diagnosis. In addition, MVD values were compared within each marker, between each marker, and were also compared to clinico-pathological data. Results Advanced age and tumor size were related to shorter survival times. There were no statistically significant differences in distributions of survival times and times to relapse between levels of MVD variables. There was no

    Axillary node status after induction chemotherapy for locally advanced breast cancer has been shown on multivariate analysis to be an independent predictor of relapse. However, it has been postulated that responders to induction chemotherapy with a clinically negative axilla could be spared the burden of lymphadenectomy, because most of them will not show histological nodal invasion. P-glycoprotein expression in the rescue mastectomy specimen has finally been identified as a significant predictor of patient survival. We studied the expression of the genes encoding multidrug resistance associated protein (MDR1) and lung cancer associated resistance protein (LRP) in formalin-fixed, paraffin-embedded tumor samples from 52 patients treated for locally advanced breast cancer by means of induction chemotherapy followed by rescue mastectomy. P-glycoprotein expression was assessed by means of immunohistochemistry before treatment in 23 cases, and by means of reverse-transcriptase-mediated polymerase chain reaction (RT-PCR) after treatment in 46 (6 failed). LRP expression was detected by means of immunohistochemistry, with the LRP-56 monoclonal antibody, in 31 cases before treatment. Immunohistochemistry for detecting the expression of c-erb-B2, p53, Ki67, estrogen receptor and progesterone receptor are routinely performed in our laboratory in every case, and the results obtained were included in the study. All patients had received between two and six cycles of standard 5-fluorouracil, doxorubicin and cyclophosphamide (FAC) chemotherapy, with two exceptions [one patient received four cycles of a docetaxel-adriamycin combination, and the other four cycles of standard cyclophosphamide-methotrexate-5-fluorouracil (CMF) polychemotherapy]. Response was assessed in accordance with the Response Evaluation Criteria In Solid Tumors (RECIST). By these, 2 patients achieved a complete clinical response, 37 a partial response, and the remaining 13 showed stable disease. This makes a

    Breast cancer is the most frequent localization of malignant process in American women and women of European countries. To date it is not possible to control the morbidity growth due to lack of effective ways of primary prevention. Comparing the incidence of breast cancer in developed countries with the countries of Asia and Africa, there is the fact of population predominance lesion in more urbanized countries. This suggests that the environment along with other factors, occupies a significant place in the initiation and progression of breast neoplasia. The impressive rates of industrial development led to the pollution of soil, surface water and, as a consequence, food by heavy metal salts.The purposes of this paper are as follows: the chemical composition determination of neoplastic breast tissue, evaluation of the DNA methylation level, study of prognostic-important receptors expression in the breast cancer cells, establishing linkages between all the derived indicators. In our study we used the following methods: studying of the chemical composition of breast cancer tissue by atomic absorption spectrophotometry and energy-dispersion spectrometer; іmmunohistochemical study of ER, PR, HER2/neu, p53, Ki-67, E-cadherin and MGMT receptors; DNA extraction and investigation by oscillating infrared spectroscopy method. The total amount of heavy metals in breast cancer tissue ranged from 51.21 × 10 -3 to 84.86 × 10 -3  μg/kg. We have got the following results: the growth of heavy metals in neoplastic tissue is accompanied with the increase of HER2/neu, p53, Ki-67, MGMT expression and decrease of ER and PR expression. The increment of pathological DNA methylation is accompanied with the increasing amount of heavy metals in tumor tissue. Heavy metals through different pathogenetic links stimulate the progression of breast cancer and reduce its sensitivity to treatment. DNA of tumor tissue has a different level of methylation which changes with the amount of

    Pregnancy-associated breast cancer (PABC) constitutes 7% of all BCs in young women. The prognosis of PABC remains controversial. In this study, we evaluated the impact of the association of pregnancy with BC on the rates of overall survival (OS), disease free survival (DFS), and distant and local recurrence-free survival. We conducted a retrospective unicenter case-control study. We enrolled PABC patients treated at our institution between 1992 and 2009. For each case, 2 BC controls were matched for age and year of diagnosis. Univariate and multivariate analyses were performed to assess the parameters associated with prognosis. Eighty-seven PABC patients were enrolled and matched with 174 controls. The univariate analysis did not reveal any significant differences in OS, DFS or distant recurrence rates between the 2 groups. Pregnancy associated status, a tumor larger than T2 and neoadjuvant chemotherapy as the primary treatment were significantly associated with an increased risk of local relapse. The multivariate analysis showed that the pregnancy associated status and the tumor size were strong prognostic factors of local recurrence. Pregnancy associated status negates the prognostic value of tumor size, as both T0-T2 and T3-T4 PABC patients have the same poor prognosis as control BC patients with T3-T4 tumors. Interestingly, although PABC patients have more locally advanced tumors, they did not have a higher rate of radical surgery than the control BC patients. Pregnancy associated status is a strong prognostic factor of local relapse in BC. In PABC patients, when possible, radical surgery should be the preferred first treatment step.

    NASA's Marshall Space Flight Center (MSFC) is sponsoring research with Bioreactors, rotating wall vessels designed to grow tissue samples in space, to understand how breast cancer works. This ground-based work studies the growth and assembly of human mammary epithelial cells (HMEC) from breast cancer susceptible tissue. Radiation can make the cells cancerous, thus allowing better comparisons of healthy vs. tunourous tissues. Here, two High-Aspect Ratio Vessels turn at about 12 rmp to keep breast tissue constructs suspended inside the culture media. Syringes allow scientists to pull for analysis during growth sequences. The tube in the center is a water bubbler that dehumidifies the air to prevent evaporation of the media and thus the appearance of destructive bubbles in the bioreactor.

    2013-01-01

    Using the 1957-2011 data from the Wisconsin Longitudinal Study, I integrate the gender relations theory, a life course perspective, and a biosocial stress perspective to explore the effect of women's job authority in 1975 (at age 36) and 1993 (at age 54) on breast cancer incidence up to 2011. Findings indicate that women with the authority to hire, fire, and influence others' pay had a significantly higher risk of a breast cancer diagnosis over the next 30 years compared to housewives and employed women with no job authority. Because job authority conferred the highest risk of breast cancer for women who also spent more hours dealing with people at work in 1975, I suggest that the assertion of job authority by women in the 1970s involved stressful interpersonal experiences, such as social isolation and negative social interactions, that may have increased the risk of breast cancer via prolonged dysregulation of the glucocorticoid system and exposure of breast tissue to the adverse effects of chronically elevated cortisol. This study contributes to sociology by emphasizing gendered biosocial pathways through which women's occupational experiences become embodied and drive forward physiological repercussions.

    1996-01-01

    Approximately 20% of breast cancer patients have a family history of the disease, and in one-fourth of these cases breast cancer appears to be inherited as an autosomally dominant trait. Five genes and gene regions involved in breast cancer susceptibility have been uncovered. Germ-line mutations in the recently cloned BRCA1 gene at 17q21 is considered to be responsible for the disease in a majority of the breast-ovarian cancer families and in 40-45% of the site-specific breast cancer families, but appears not to be involved in families with both male and female breast cancer cases. The BRCA2 locus at 13q12-q13 appears to be involved in 40-45% of the site-specific breast cancer families, and in most of the families with affected males. The gene located in this region, however, does not seem to confer susceptibility to ovarian cancer. The TP53 gene is involved in breast cancer development in the Li-Fraumeni syndrome and Li-Fraumeni syndrom-like families, whereas germ-line mutations in the androgen receptor (AR) gene is present in a subset of male breast cancers. Furthermore, females who are obligate carriers of ataxia telangiectasia (AT) have a 4-12 times relative risk of developing breast cancer as compared with the general female population, indicating that germ-line mutations in AT also confer susceptibility to breast cancer.

    Between January 1970 and December 1978 39 patients with isolated supraclavicular recurrence of breast cancer were referred to the Department of Radiotherapy and Radiobiology, University of Vienna. All patients have had mastectomy as primary treatment. In 46% of the patients a surgical excision of involved lymph node has been performed before irradiation. The median interval between mastectomy and supraclavicular recurrence was 26 months. The cumulative incidence after three years was 75%. 15 patients have shown complete local response during the whole follow-up time. In 38 patients, osseous and/or visceral metastasis were observed after a median interval of eight months. After two years, 87% of the patients presented distant disease. 15 patients suffered on local pain in the supraclavicular region or in the ipsilateral shoulder with lymph oedema of the arm. The median survival after therapy was 18 months. The death rate after three years was 77%. Patients with a recurrence-free intervall after mastectomy less than two years had a median survival time of eleven months whereas patients with a recurrence-free interval had 26 months. (orig.) [de

    As breast cancer outcomes improve and more people with breast cancer survive longer following diagnosis, many survivors must deal with the effects of treatment. Some adverse effects last a short time and have little influence on breast cancer patients' quality of life, yet others can cause long-term complications and add to increased morbidity and mortality among survivors. This article reviews the adverse effects of breast cancer treatments and how they affect the health and quality of life of those receiving treatment. The article also explains how adverse effects can interrupt treatment and how physicians and survivors can manage adverse effects of breast cancer treatment.

    Full Text Available Inflammatory breast cancer is one of the most aggressive forms of breast cancer. Once considered to be a uniformly fatal disease, treatment of this entity has evolved significantly over the last two decades. In this article, we review the epidemiology, pathology, biologic underpinnings, radiologic advances, and treatment modalities for inflammatory breast cancer. Updates in surgical therapy, medical oncologic therapy and radiation therapy are reviewed. Emphasis is on cutting edge information regarding inflammatory breast cancer. The management of inflammatory breast cancer is best served by a multidisciplinary team. Continued research into molecular pathways and potential targets is imperative. Future clinical trials should include evaluation of conventional therapy with targeted therapies.

    1997-01-01

    Breast cancer is the most common malignancy among women in the Western society. Over the past decades it has become apparent that breast cancer incidence rates are increasing steadily, whereas the mortality rates for breast cancer have remained relatively constant. Information through the media on this rising number of cases has increased breast health awareness but has also introduced anxiety in the female population. This combination of factors has made the need for prevention of breast cancer an urgent matter. Breast cancer does not seem to be a single disease entity. A specific etiologic factor may therefore have more influence on one form may therefore have more influence on one form of breast cancer than another. So far though, as shown in their summary of current knowledge on established and dubious risk factors, no risk factors have been identified that can explain a major part of the incidence. Efforts to identify other ways for primary prevention have also been discouraging, even though breast cancer is one of the most investigated tumours world-wide. Thus, at this point i time, the most important strategy to reduce breast cancer mortality is early detection through individual counselling and organised breast screening programs. The recent isolation of breast cancer susceptibility genes may introduce new ways to reduce the risk of breast cancer in a small subset of women

    Full Text Available Abstract Background NUCKS (Nuclear, Casein Kinase and Cyclin-dependent Kinase Substrate is a nuclear, DNA-binding and highly phosphorylated protein. A number of reports show that NUCKS is highly expressed on the level of mRNA in several human cancers, including breast cancer. In this work, NUCKS expression on both RNA and protein levels was studied in breast tissue biopsies consisted of invasive carcinomas, intraductal proliferative lesions, benign epithelial proliferations and fibroadenomas, as well as in primary cultures derived from the above biopsies. Specifically, in order to evaluate the level of NUCKS protein in correlation with the histopathological features of breast disease, immunohistochemistry was employed on paraffin sections of breast biopsies of the above types. In addition, NUCKS expression was studied by means of Reverse Transcription PCR (RT-PCR, real-time PCR (qRT-PCR and Western immunoblot analyses in the primary cell cultures developed from the same biopsies. Results The immunohistochemical Results showed intense NUCKS staining mostly in grade I and II breast carcinomas compared to normal tissues. Furthermore, NUCKS was moderate expressed in benign epithelial proliferations, such as adenosis and sclerosing adenosis, and highly expressed in intraductal lesions, specifically in ductal carcinomas in situ (DCIS. It is worth noting that all the fibroadenoma tissues examined were negative for NUCKS staining. RT-PCR and qRT-PCR showed an increase of NUCKS expression in cells derived from primary cultures of proliferative lesions and cancerous tissues compared to the ones derived from normal breast tissues and fibroadenomas. This increase was also confirmed by Western immunoblot analysis. Although NUCKS is a cell cycle related protein, its expression does not correlate with Ki67 expression, neither in tissue sections nor in primary cell cultures. Conclusion The results show overexpression of the NUCKS protein in a number of non

    Purpose: To compare the quality-adjusted life expectancy between women treated with partial breast irradiation (PBI) vs. whole breast radiotherapy (WBRT) for estrogen receptor-positive early-stage breast cancer. Methods and Materials: We developed a Markov model to describe health states in the 15 years after radiotherapy for estrogen receptor-positive early-stage breast cancer. Breast cancer recurrences were separated into local recurrences and elsewhere failures. Ipsilateral breast tumor recurrence (IBTR) risk was extracted from the Oxford overview, and rates and utilities were adapted from the literature. We studied two cohorts of women (aged 40 and 55 years), both of whom received adjuvant tamoxifen. Results: Assuming a no evidence of disease (NED)-PBI utility of 0.93, quality-adusted life expectancy after PBI (and WBRT) was 12.61 (12.57) and 12.10 (12.06) years for 40-year-old and 55-year-old women, respectively. The NED-PBI utility thresholds for preferring PBI over WBRT were 0.923 and 0.921 for 40-year-old and 55-year-old women, respectively, both slightly greater than the NED-WBRT utility. Outcomes were sensitive to the utility of NED-PBI, the PBI hazard ratio for local recurrence, the baseline IBTR risk, and the percentage of IBTRs that were local. Overall the degree of superiority of PBI over WBRT was greater for 55-year-old women than for 40-year-old women. Conclusions: For most utility values of the NED-PBI health state, PBI was the preferred treatment modality. This result was highly sensitive to patient preferences and was also dependent on patient age, PBI efficacy, IBTR risk, and the fraction of IBTRs that were local

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast. Cancer detection rate by mammography was 3.3 per 1000 patients and that by US was 5.0 per 1000 patients, therefore overall cancer detection rate by

    While the deregulation of iron homeostasis in breast epithelial cells is acknowledged, iron-related alterations in stromal inflammatory cells from the tumor microenvironment have not been explored. Immunohistochemistry for hepcidin, ferroportin 1 (FPN1), transferrin receptor 1 (TFR1) and ferritin (FT) was performed in primary breast tissues and axillary lymph nodes in order to dissect the iron-profiles of epithelial cells, lymphocytes and macrophages. Furthermore, breast carcinoma core biopsies frozen in optimum cutting temperature (OCT) compound were subjected to imaging flow cytometry to confirm FPN1 expression in the cell types previously evaluated and determine its cellular localization. We confirm previous results by showing that breast cancer epithelial cells present an ‘iron-utilization phenotype’ with an increased expression of hepcidin and TFR1, and decreased expression of FT. On the other hand, lymphocytes and macrophages infiltrating primary tumors and from metastized lymph nodes display an ‘iron-donor’ phenotype, with increased expression of FPN1 and FT, concomitant with an activation profile reflected by a higher expression of TFR1 and hepcidin. A higher percentage of breast carcinomas, compared to control mastectomy samples, present iron accumulation in stromal inflammatory cells, suggesting that these cells may constitute an effective tissue iron reservoir. Additionally, not only the deregulated expression of iron-related proteins in epithelial cells, but also on lymphocytes and macrophages, are associated with clinicopathological markers of breast cancer poor prognosis, such as negative hormone receptor status and tumor size. The present results reinforce the importance of analyzing the tumor microenvironment in breast cancer, extending the contribution of immune cells to local iron homeostasis in the tumor microenvironment context

    Breast cancer is a leading cause of death amongst women, several studies have shown significant association between alcohol consumption and breast cancer. The aim of this overview is to highlight some of the mechanisms by which alcohol consumption could increase the risk of developing breast cancer. Using online Medline search engine, article containing details about mechanisms which explain the link between alcohol and breast cancer were examined. A number of mechanisms were found by which alcohol could increase the risk of breast cancer, alcohol's interaction and effect on oestrogen secretion; number of oestrogen receptors; the generation of acetaldehyde and hydroxyl free radicals; cells migration and metastasis; secretion of IGF1 and interaction with HRT and folate metabolism. In conclusion, it is essential for clinicians to understand these mechanisms and inform patients of the link between alcohol and breast cancer. Breast cancer; Alcohol; Mechanisms.

    Full Text Available Breast cancer is the most common malignancy in women in well-developed countries. Despite a constant increase in its incidence, the percentage of patients diagnosed with the disease in the non-invasive stage is also rising. This allows more frequently for the use of breast-preserving surgical techniques, involving the breast and the regional lymphatic system. According to current guidelines of expert panels and research societies, the recommended method of identifying the sentinel lymph node is the use of an isotope marker with a dye (a combined isotope and dye method. Cooperation with a nuclear medicine unit is essential (performing a preoperative lymphoscintigraphic scan to identify the lymphatic drainage basin and sentinel lymph node. In the case of smaller centers treating breast cancer, it can be associated with a number of difficulties, including organizational ones, and also increasing general treatment costs. A possible solution to these problems is to use alternative techniques of visualizing the sentinel lymph node, which do not require a radiotracer. In this paper we discuss the currently available methods of mapping the lymphatic system of the axillary region in patients with early breast cancer. The review is limited to reporting on methods of proven (based on clinical research high diagnostic value.

  4. Microbial dysbiosis is associated with human breast cancer.

    Full Text Available Breast cancer affects one in eight women in their lifetime. Though diet, age and genetic predisposition are established risk factors, the majority of breast cancers have unknown etiology. The human microbiota refers to the collection of microbes inhabiting the human body. Imbalance in microbial communities, or microbial dysbiosis, has been implicated in various human diseases including obesity, diabetes, and colon cancer. Therefore, we investigated the potential role of microbiota in breast cancer by next-generation sequencing using breast tumor tissue and paired normal adjacent tissue from the same patient. In a qualitative survey of the breast microbiota DNA, we found that the bacterium Methylobacterium radiotolerans is relatively enriched in tumor tissue, while the bacterium Sphingomonas yanoikuyae is relatively enriched in paired normal tissue. The relative abundances of these two bacterial species were inversely correlated in paired normal breast tissue but not in tumor tissue, indicating that dysbiosis is associated with breast cancer. Furthermore, the total bacterial DNA load was reduced in tumor versus paired normal and healthy breast tissue as determined by quantitative PCR. Interestingly, bacterial DNA load correlated inversely with advanced disease, a finding that could have broad implications in diagnosis and staging of breast cancer. Lastly, we observed lower basal levels of antibacterial response gene expression in tumor versus healthy breast tissue. Taken together, these data indicate that microbial DNA is present in the breast and that bacteria or their components may influence the local immune microenvironment. Our findings suggest a previously unrecognized link between dysbiosis and breast cancer which has potential diagnostic and therapeutic implications.

    To assess the diagnostic performance of pretreatment (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) and its impact on radiation therapy treatment decisions in patients with locally advanced breast cancer (LABC). Patients with LABC with Eastern Cooperative Oncology Group performance status breast mammography and ultrasound, bone scan, and CT chest, abdomen, and pelvis scans performed. Informed consent was obtained before enrolment. Pretreatment whole-body (18)F-FDG PET/CT scans were performed on all patients, and results were compared with CI findings. A total of 154 patients with LABC with no clinical or radiologic evidence of distant metastases on CI were enrolled. Median age was 49 years (range, 26-70 years). Imaging with PET/CT detected distant metastatic disease and/or locoregional disease not visualized on CI in 32 patients (20.8%). Distant metastatic disease was detected in 17 patients (11.0%): 6 had bony metastases, 5 had intrathoracic metastases (pulmonary/mediastinal), 2 had distant nodal metastases, 2 had liver metastases, 1 had pulmonary and bony metastases, and 1 had mediastinal and distant nodal metastases. Of the remaining 139 patients, nodal disease outside conventional radiation therapy fields was detected on PET/CT in 15 patients (10.8%), with involvement of ipsilateral internal mammary nodes in 13 and ipsilateral level 5 cervical nodes in 2. Imaging with PET/CT provides superior diagnostic and staging information in patients with LABC compared with CI, which has significant therapeutic implications with respect to radiation therapy management. Imaging with PET/CT should be considered in all patients undergoing primary staging for LABC. Crown Copyright © 2015. Published by Elsevier Inc. All rights reserved.

    To explore the relationship between basal {sup 18}F-FDG PET/CT information in breast tumours and survival in locally advanced breast cancer (LABC). This prospective, multicentre study included 198 women diagnosed with LABC. All patients underwent {sup 18}F-FDG PET/CT prior to treatment. The maximum standardized uptake value (SUVmax) in tumor (T), lymph nodes (N) and the N/T ratio was obtained in all cases. Stage according to PET/CT imaging (metabolic stage) and conventional imaging techniques (clinical stage) was established. During follow-up, patient status was established (disease free status or not). The relationship between all the variables and overall survival (OS) and disease-free survival (DFS) was analysed using the Kaplan-Meier and Cox regression methods. A ROC analysis was performed to obtain a cut-off value of SUVmax that was useful in the prediction of outcome. The mean SUVmax ± SD values in the primary tumour, lymph nodes and the SUVmax N/T index were 7.40 ± 5.57, 4.17 ± 4.74 and 0.73 ± 1.20, respectively. Higher semiquantitative metabolic values were found in more advanced metabolic and clinical stages. During follow-up, 78.4 % of patients were free of disease. Significant relationships were observed between SUVT and SUVN and patient status. With respect to OS and DFS, significant differences were detected for the metabolic stage. Kaplan-Meier analysis revealed that using the cut-off values, a primary-tumour SUVmax ≥ 6.05 or a nodal SUVmax ≥2.25 were significantly correlated with DFS and OS. PET imaging with {sup 18}F-FDG offers prognostic information for LABC that can be obtained preoperatively and noninvasively. (orig.)

    Purpose: We sought to determine the rate at which regional nodal ultrasonography would increase the nodal disease stage in patients with triple-negative breast cancer (TNBC) beyond the clinical stage determined by physical examination and mammography alone, and significantly affect the treatments delivered to these patients. Methods and Materials: We retrospectively reviewed the charts of women with stages I to III TNBC who underwent physical examination, mammography, breast and regional nodal ultrasonography with needle biopsy of abnormal nodes, and definitive local-regional treatment at our institution between 2004 and 2011. The stages of these patients' disease with and without ultrasonography of the regional nodal basins were compared using the Pearson χ{sup 2} test. Definitive treatments of patients whose nodal disease was upstaged on the basis of ultrasonographic findings were compared to those of patients whose disease stage remained the same. Results: A total of 572 women met the study requirements. In 111 (19.4%) of these patients, regional nodal ultrasonography with needle biopsy resulted in an increase in disease stage from the original stage by physical examination and mammography alone. Significantly higher percentages of patients whose nodal disease was upstaged by ultrasonographic findings compared to that in patients whose disease was not upstaged underwent neoadjuvant systemic therapy (91.9% and 51.2%, respectively; P<.0001), axillary lymph node dissection (99.1% and 34.5%, respectively; P<.0001), and radiation to the regional nodal basins (88.2% and 29.1%, respectively; P<.0001). Conclusions: Regional nodal ultrasonography in TNBC frequently changes the initial clinical stage and plays an important role in treatment planning.

    To explore the relationship between basal (18) F-FDG PET/CT information in breast tumours and survival in locally advanced breast cancer (LABC). This prospective, multicentre study included 198 women diagnosed with LABC. All patients underwent (18) F-FDG PET/CT prior to treatment. The maximum standardized uptake value (SUVmax) in tumor (T), lymph nodes (N) and the N/T ratio was obtained in all cases. Stage according to PET/CT imaging (metabolic stage) and conventional imaging techniques (clinical stage) was established. During follow-up, patient status was established (disease free status or not). The relationship between all the variables and overall survival (OS) and disease-free survival (DFS) was analysed using the Kaplan-Meier and Cox regression methods. A ROC analysis was performed to obtain a cut-off value of SUVmax that was useful in the prediction of outcome. The mean SUVmax ± SD values in the primary tumour, lymph nodes and the SUVmax N/T index were 7.40 ± 5.57, 4.17 ± 4.74 and 0.73 ± 1.20, respectively. Higher semiquantitative metabolic values were found in more advanced metabolic and clinical stages. During follow-up, 78.4 % of patients were free of disease. Significant relationships were observed between SUVT and SUVN and patient status. With respect to OS and DFS, significant differences were detected for the metabolic stage. Kaplan-Meier analysis revealed that using the cut-off values, a primary-tumour SUVmax ≥ 6.05 or a nodal SUVmax ≥2.25 were significantly correlated with DFS and OS. PET imaging with (18) F-FDG offers prognostic information for LABC that can be obtained preoperatively and noninvasively.

    Purpose: To assess the diagnostic performance of pretreatment {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) and its impact on radiation therapy treatment decisions in patients with locally advanced breast cancer (LABC). Methods and Materials: Patients with LABC with Eastern Cooperative Oncology Group performance status <2 and no contraindication to neoadjuvant chemotherapy, surgery, and adjuvant radiation therapy were enrolled on a prospective trial. All patients had pretreatment conventional imaging (CI) performed, including bilateral breast mammography and ultrasound, bone scan, and CT chest, abdomen, and pelvis scans performed. Informed consent was obtained before enrolment. Pretreatment whole-body {sup 18}F-FDG PET/CT scans were performed on all patients, and results were compared with CI findings. Results: A total of 154 patients with LABC with no clinical or radiologic evidence of distant metastases on CI were enrolled. Median age was 49 years (range, 26-70 years). Imaging with PET/CT detected distant metastatic disease and/or locoregional disease not visualized on CI in 32 patients (20.8%). Distant metastatic disease was detected in 17 patients (11.0%): 6 had bony metastases, 5 had intrathoracic metastases (pulmonary/mediastinal), 2 had distant nodal metastases, 2 had liver metastases, 1 had pulmonary and bony metastases, and 1 had mediastinal and distant nodal metastases. Of the remaining 139 patients, nodal disease outside conventional radiation therapy fields was detected on PET/CT in 15 patients (10.8%), with involvement of ipsilateral internal mammary nodes in 13 and ipsilateral level 5 cervical nodes in 2. Conclusions: Imaging with PET/CT provides superior diagnostic and staging information in patients with LABC compared with CI, which has significant therapeutic implications with respect to radiation therapy management. Imaging with PET/CT should be considered in all patients undergoing primary

    and optimal use of these agents for the treatment of breast cancer. Currently, the most promising approach has been the use of bevacizumab, a humanized monoclonal antibody directed against the most potent pro-angiogenic factor, vascular endothelial growth factor (VEGF). Small molecular inhibitors of VEGF...... tyrosine kinase activity, such as sorafenib, appear promising. While, the role of sunitinib and inhibitors of mammalian target of rapamycin (mTOR) in breast cancer has to be defined. Several unanswered questions remain, such as choice of drug(s), optimal duration of therapy and patient selection criteria......ABSTRACT: Angiogenesis is an important component of cancer growth, invasion and metastasis. Therefore, inhibition of angiogenesis is an attractive strategy for treatment of cancer. We describe existing clinical trials of antiangiogenic agents and the challenges facing the clinical development...

    Full Text Available Background: Erythropoietin (Epo is an important regulator of erythropoiesis, and controls proliferation and differentiation of both erythroid and non-erythroid tissues. Epo is actively synthesized by breast cells during lactation, and also plays a role in breast tissues promoting hypoxia-induced cancer initiation. Our aims are to perform an exploratory investigation on the Epo accumulation in breast secretions from healthy and cancer patients and its localization in breast cancer cells.

  16. Understanding and potentially reducing second breast cancer

    Full text: Long term survival after breast cancer diagnosis has increased markedly in the last decade: 15-year relative survival after breast cancer diagnosis is now 75% in the US. Associated with these excellent survival prospects, however, long term studies suggest that contralateral second breast cancer rates are in the range from 10 to 15% at 15 years post treatment, and are still higher for BRCA1/2 carriers, as well as for still longer term survivors. These second cancer risks are much higher than those for a comparable healthy woman to develop a first breast cancer. It follows that women with breast cancer are highly prone to develop a second breast cancer. We propose here a new option for reducing the disturbingly high risk of a contralateral second breast cancer. in patients with both estrogen positive and negative primary breast cancer: prophylactic mammary irradiation (PMI) of the contralateral breast. The rationale behind PMI is evidence that standard post-Iumpectomy radiotherapy of the affected (ipsilateral) breast substantially reduces the long-term genetically-based second cancer risk in the ipsilateral breast, by killing the existing premalignant cells in that breast. This suggests that there are relatively few premalignant cells in the breast (hundreds or thousands, not millions), so even a fairly modest radiation cell-kill level across the whole breast would be expected to kill essentially all of them. If this is so, then a modest radiation dose-much lower than that to the affected breast--delivered uniformly to the whole contralateral breast, and typically delivered at the same time as the radiotherapy of the ipsilateral breast, would have the potential to markedly reduce second-cancer risks in the contralateral breast by killing essentially all the pre-malignant cells in that breast while causing only a very low level of radiation-induced sequelae. Therefore we hypothesize that low-dose prophylactic mammary irradiation of the contralateral breast

    Some questions about mass screening in breast cancer are answered it being concluded that: 1. mass screening for the detection of early breast cancer is the only means with proven potential for lowering the death rate of the disease; 2. mammography is an importante - if not the most important modality in mass screening; 3. new film - screen combinations generally available are capable of producing mammograms of excelent quality with radiation doses down to .1 rad into the body of breast. The risk of malignant changes from such dosage - even when given periodically is negligeable. New equipment, to be available, shortly, will use the new film - screen combinations in an automated manner with must reduce cost in time, filme, personnel and processing - of more than 50%. This would make mass screening more practical. (M.A.) [pt

    Full Text Available The management of breast cancer is perhaps the most controversial of all and has evolved a sea change over the years. Contrast enhanced MRI imaging is emerging as the most efficient imaging diagnostic tool. Newer approaches for the biopsy of inoperable breast cancer are aimed at obtaining diagnostically adequate tissue samples while minimizing invasiveness and the risk of complications. The regional vigour that Halsted followed rigorously, albeit, achieved significant locoregional control, could not lead to improved long-term survival. With the passage of time, people have understood the systemic nature of the disease and the paramount need to incorporate systemic treatment even in relatively earlier stages and curtain surgical ablative techniques. The role of primary systemic therapy in the management of breast cancer is fast emerging as a vital option. In HER 2/neu gene overexpressed patients, addition of trastuzumab to the systemic treatment is a distinct improvement in overall survival.
