  • Background: Prognosis of breast cancer depends on classic pathological factors and also tumor angiogenesis. This study aimed to evaluate the clinicopathological factors of breast cancer in a tertiary centre with a focus on the relationship between tumor angiogenesis and clinicopathological factors. Methods: Clinicopathological data were retrieved from the archived formal pathology reports for surgical specimens diagnosed as invasive ductal carcinoma, NOS. Microvessels were immunohistochemically stained with anti-CD34 antibody and quantified as microvessel density. Results: At least 50% of 94 cases of invasive breast ductal carcinoma in the study were advanced stage. The majority had poor prognosis factors such as tumor size larger than 50mm (48.9%), positive lymph node metastasis (60.6%), and tumor grade III (52.1%). Higher percentages of estrogen and progesterone receptor negative cases were recorded (46.8% and 46.8% respectively). Her-2 overexpression cases and triple negative breast cancers constituted 24.5% and 22.3% respectively. Significantly higher microvessel density was observed in the younger patient age group (p=0.012). There were no significant associations between microvessel density and other clinicopathological factors (p>0.05). Conclusions: Majority of the breast cancer patients of this institution had advanced stage disease with poorer prognostic factors as compared to other local and western studies. Breast cancer in younger patients might be more proangiogenic.

  • We previously reported the involvement of zinc-finger protein 143 (ZNF143) on cancer cell motility in colon cancer cells. Here, ZNF143 was further characterized in breast cancer. Immunohistochemistry was used to determine the expression of ZNF143 in normal tissues and in tissues from metastatic breast cancer at various stages. Notably, ZNF143 was selectively expressed in duct and gland epithelium of normal breast tissues, which decreased when the tissue became malignant. To determine the molecular mechanism how ZNF143 affects breast cancer progression, it was knocked down by infecting benign breast cancer cells with short-hairpin (sh) RNA-lentiviral particles against ZNF143 (MCF7 sh-ZNF143). MCF7 sh-ZNF143 cells showed different cell-cell contacts and actin filament (F-actin) structures when compared with MCF7 sh-Control cells. In migration and invasion assays, ZNF143 knockdown induced increased cellular motility in breast carcinoma cells. This was reduced by the recovery of ZNF143 expression. Taken together, these results suggest that ZNF143 expression contributes to breast cancer progression.

  • Background: Breast cancer is the most prevalent malignancy among women with wide differences in clinical profile from region to region. The present study aimed to describe the profile of breast cancer patients attending a tertiary care hospital in Marathwada region of Western India. Materials and Methods: In this descriptive retrospective study, we reviewed records of pathologically diagnosed patients of breast cancer managed at our center from years 2009 to 2015. Data with respect to demographic status, detailed past, medical, familial and personal history, findings of clinical examination and histological features were obtained. Patients were staged according to the Tumor Node Metastasis (TNM) system. Results: Among 260 cases, mean age of presentation was 52.6, with average age of menarche of 11.3 and menopause of 52.6 years. The majority of patients were from urban regions and were postmenopausal (64.3%). Main clinical features presentation were breast lumps. Most patients were in stage II and had infiltrating duct carcinomas. Conclusions: Most common risk factors for breast cancer observed are increasing age, low parity and obesity. Breast cancer was more prevalent among postmenopausal women presenting in stage II with infiltating duct carcinoma in our region of India.

  • Malignant peripheral nerve sheath tumor (MPNST), a rare soft-tissue sarcoma, is most commonly located in the trunk, extremities, and head and neck, but rare in the breast. We report a metastatic breast MPNST in a 27-year-old woman with neurofibromatosis type 1 (NF-1). Chest computed tomography revealed a well-defined, oval, mildly enhancing nodule in the right breast. US revealed a circumscribed, oval, heterogeneous echoic mass with vascularity and intermediate elasticity in the right upper outer breast. The breast mass was excised and diagnosed as MPNST on histopathology evaluation. Although rare, it should be included in the differential diagnosis of breast mass in NF-1 patient.

  • Introduction and Purpose: The frequency of bilateral breast cancer is 1.4-11.0% among all breast cancers. It can present as synchronous (SC) or metachronous (MC). Data regarding clinical course of bilateral breast cancer are scarce. In this study, we therefore evaluated demographic, pathological and clinical characteristics, treatments and responses in bilateral breast cancer cases; making distinctions between metachronous-synchronous and comparing with historic one-sided data for the same parameters. Materials and Methods: One hundred fifty bilateral breast cancer cases from ten different centers between 2000 and 2011 were retrospectively scanned. Age of the cases, family history, menopausal status, pathological features, pathological stages, neoadjuvant, surgery, adjuvant and palliative chemotherapy/radiotherapy were examined in the context of the first and second occurrence and discussed with reference to the literature. Results: Metachronous and synchronous groups showed similar age, menopausal status, tumor type, HER2/neu expression; the family history tumor grade, tumor stage, ER-negativity rate, local and distant metastases rates, surgery, adjuvant chemotherapy application rates were identified as significantly different. Palliative chemotherapy response rate was greater in the metachronous group but median PFS rates did not differ between the groups. Conclusion: Although bilateral breast cancer is not frequent, MC breast cancer is different from SC breast cancer by having more advanced grade, stage, less ER expression, more frequent rates of local relapse and distant metastasis and better response to chemotherapy in case of relapse/metastasis.

  • In the past, most patient of breast cancer suffered side effects due to the useless removement of Axillary Lymph Node, but there is no need to remove it because of the result in this study. The purpose of this study is to save surgery time and side effects after surgical operation for patients with breast cancer by making decisions of operation range for metastasis in first Stenosis Lymph Node using the $^{99m}Tc-Tincolloid$ Scintigraphy and the Micro Probe for radioisotope. As a result of this study, 15 among 20 patients became objects of this study could reduced side effects for operation because there were no axillary lymph node operations. However there is no standard for method of this treatment. It should be standardize where inject point is, how much $^{99m}Tc-Tincolloid$ should be injected(radioactivity value), and the need of massage and Lymph Scintigraphy. Nevertheless I think that this result of study is useful to reduce suffering and side effects from breast cancer and also we should try to do that continuously. The objects for this study were 20 patients diagnosed as breast cancer by Ultrasonography, Mammography & Biopsy. The average of patient age was 45.4 years and its range was between 31 and 71 years. In case of clinical period there were 9 patients of Period I and II patients of Period III. The equipment for this study were $^{99m}Tc-Tincolloid$ describing the Stenosis Lymph Node as a tracer, Micro Probe : Neoprobe 2000(the rest is Gamma Probe) tracing the location, and MS-II Gamma Camera : SIEMENS(the rest is MS-II Gamma Camera) describing the images. There were 3 methods for this study, after selecting one of those methods all 20 patients were performed Stenosis Lymph Node diagnosis & Gamma Probe in operation room. The result was that I imaged all the 20 patients, and seek the Stenosis Lymph Node by using Gamma Probe. Metastasis in Stenosis Lymph Node was 5 and Metastasis in Axillary Lymph Node was 3 between Metastasis in Stenosis Lymph Node cases. Finally 15 patients were also proved that Axillary Lymph Node was Positive and that means there was no Metastasis in Axillary Lymph Node.

  • Fibrous dysplasia is a common benign disorder of bone in which normal bone marrow is replaced with fibro-osseous tissue. As PET/CT is increasingly used for the staging of different malignant disease, incidentally found fibrous dysplasia with increased FDG uptake may mimic metastasis. We report on a 46-year-old woman with fibrous dysplasia who underwent PET/CT because of suspected recurrence of breast cancer and was misdiagnosed as a bony metastasis with a focal FDG uptake on left proximal femur. This lesion was interpreted as fibrous dysplasia based on MRI in addition to the plain radiographs. We conclude that MRI in addition to radiography may help to differentiate fibrous dysplasia mimicking metastasis on PET/CT in the patients with malignancy.

  • In the course of our studies for new anticancer medicinal plants, we evaluated the effects of an alcohol-water (1:1, V/V) extract of Dendrostellera lesserii (Thymelaeaceae) leaves on the growth rates of breast tumors of rats. The breast tumors were induced in a group of rats by Dimethylbenz[a]anthracene (DMBA) injection. Our data showed that daily oral feeding of the crude extract to the rats, for 20 consecutive weeks, significantly repressed the growth rates of the breast tumors. In addition, the probable effect of D. lessertii crude extract or one of its purified active components on metastasis was evaluated using wehi-164 cells. Treatment of the cells with a single nontoxic dose of the purified active component for 48 hours inhibited the adhesion of the cells to the immobilized fibronectin molecules by almost 80% compared to the untreated control cells.

  • Purpose : To evaluate interim results in terms of failure, cosmetic results and survival after breast conserving operation and radiation therapy in early breast cancer. Material and Methods : From January 1992 through December 1997, seventy two patients with early stage 0, I and II breast cancer were treated with conservative surgery plus radiotherapy at Keimyung University Dongsan Medical Center. Age distribution was 25 to 77 years old with median age of 43. According to TNM stage, five patients had stage 0, thirty three were stage I, twenty five were IIa, and nine were IIb. Most patients underwent excision of all gross tumor and ipsilateral axillary dissection. Breast was irradiated through medial and lateral tangential fields of 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks. We delivered a boost irradiation dose of 10 to 16 Gy in 1 to 2 weeks to excision site. Adjuvant chemotherapy was administered in forty one patients with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) regimens of 6 cycles concurrently or before radiation. Cosmetic results were assessed by questionnaire to patients grading of excellent, good, fair, poor. Follow-up periods were 22 to 91 months with median 40 months. Results : Five year disease free survival rate (5YDFS) was $95.8\%$. According to stage, 5YDFS was $100\%,\;96.9\%,\;96\%\;and\;88.9\%$ in stage 0, I, IIa and IIb, respectively. Two patients had distant metastasis and one had local and distant failure. One patient with distant failure had bone and liver metastasis at 14 months after treatment and the other had lung and both supraclavicular metastasis at 21 months after treatment. Patient with local and distant failure had local recurrence on other quadrant in same breast and then salvaged with total mastectomy and chemotherapy but she died due to brain metastasis at 55 months. Complications were radiation pneumonitis in five patients (four patients of asymptomatic, one patients of symptomatic) and hand or arm edema(4 patients). Fifty nine patients answered our cosmetic result questionnaire and cosmetic results were good to excellent in fifty one patients $(86\%)$. Conclusion : We considered that conservative surgery and radiation for the treatment of early stage invasive breast cancer was safe and had excellent survival and cosmetic results. We need to assess about prognostic factors with longer follow up and with large number of patients.

  • Purpose: There have been limited reports on breast reconstruction after excision of phyllodes tumor. This paper reports four patients who had immediate reconstruction of the breast following excision of phyllodes tumor. Methods: We retrospectively reviewed the medical records of 14 patients from March 2000 to March 2008. Clinical data were analyzed including age, presenting symptoms and signs, type of surgery and metastasis. Results: The mean age was 38.6 years. The mean follow-up period was 40.6 months. Reconstruction was performed with latissimus dorsi musculocutaneous flap in 3 patients and transverse rectus abdominis musculocutaneous flap in 1 patient. Other cases were covered with skin graft or primary repair. 2 local recurrent cases were noted. Conclusion: The breast affected by phyllodes tumor must undergo complete excision. Followed by mastectomy, immediate reconstruction of breast improved cosmetic results, and allowed a wider surgical excision margin of tumor.
