Diagnosis, Treatment Characteristics, And Survival Of Women With Breast Cancer Aged 65 And Above: A Hospital-Based Retrospective Study
Background Breast cancer incidence in women increases with age, while survival rates decrease. Studies interpret this result as meaning higher comorbidity, diagnosis at later stages of the disease, and less effective treatment in the elderly. The aim of this study is to evaluate the diagnosis and treatment characteristics of breast cancer and their effect on the survival of women aged 65 and above. Methods The data within the files of 1064 women with breast cancer, who were followed-up in Dokuz Eylul University Medical Faculty Hospital between 2000 and 2006, were reviewed retrospectively. The survival probabilities at years 1 and 5 were calculated by life table analysis. The Kaplan-Meier test was used for calculating mean survival time, and the differences between groups were evaluated by log-rank test. The backward elimination method was used for multivariate analysis, and a −2 log-likelihood ratio was used for comparison of different models. Results Of the patients, 25.3% were aged 65 and above at the time of the diagnosis. Patients in this group had more comorbidities and were more likely to be diagnosed at advanced stages than younger patients. Additionally, they had lower rates of surgical treatment, chemotherapy or radiotherapy. One and 5-year survival probabilities among age groups were 96.1% and 84.5%, respectively, for <65 years, 93.5% and 84.8%, respectively, for 65–69, 98.7% and 84.0%, respectively, for 70–74, and 85.5% and 59.6%, respectively, for 75 years and above. In the multivariate model, age, clinical stage, and comorbidity were found to be negatively associated with the survival rate. Conclusions The survival of women with breast cancer aged 65 and above was affected negatively by age at diagnosis, clinical stage, and the presence of comorbidity. Early diagnosis also is very important for elderly women. Additionally, because of higher comorbidity, their evaluation and treatment should be planned by an interdisciplinary team.PubMedWoSScopu
The only effects of recombinant follicle-stimulating hormone for ovulation induction in the pre-implantation period of rats
Objective: The aim of this study was to evaluate the changes in follicular development, serum hormonal levels, and endometrium in the pre-implantation period of rats by using recombinant FSH (rFSH) without human chorionic gonadotropin (hCG). Methods: Thirty female rats were studied in six groups of five specimens. Two groups determined as controls (groups 1 and 2). Two groups received constant doses of rFSH (groups 3 and 4) and other two decreasing doses (groups 5 and 6). One of the paired groups was mated. Uterus, ovaries, and blood samples were taken from non-mated groups (groups 1, 3, and 5) at the proestrus period and from mated groups (groups 2, 4, and 6) in the pre-implantation period. Results: In non-mated groups antral follicles and corpus luteum periodicum and in mated groups antral follicles, corpus luteum periodicum, and corpus luteum graviditatis were increased in rFSH groups, especially in decreasing dose groups. Estradiol (E2) levels were increased and progesterone (P)/E2 ratio was significantly decreased in decreasing dose groups. Endometrium surface epithelium was columnar, irregular, and folded in rFSH groups. Endometrium glandular epithelium was cuboidal in all groups. In decreasing dose groups endometrial stroma was smooth and fibroblastic. Mitotic indices of endometrium surface, glandular epithelium, and stroma were significantly decreased in rFSH groups. Primary follicles and P levels showed no change. Conclusion: It seems likely that decreasing doses of rFSH might be used in order to improve follicular development, although it has negative effects with E2 on endometrium in the pre-implantation period of rats. © 2006 Springer-Verlag
Electrolytes and Trace Elements in Human Breast Cyst Fluid
Gross cystic breast disease (GCBD) is one of the most common breast diseases, and women with apocrine (type I) cysts are at higher risk of developing breast cancer than women with flattened (type II) cysts. Type I cysts contain fluid with an electrolyte composition similar to that of intracellular fluid (Na/K ratio 3). The electrolyte composition of breast cyst fluid (BCF) has been investigated intensively; however, there have been only a few studies in literature reporting the content of trace elements in BCF. The aim of this study was to compare the concentrations of Na, K, Ca, P, Zn, Cu, Fe, and Na/K and trace element ratios in breast cyst fluid in two subgroups of breast cysts. Sixty-three BCF were obtained by needle aspiration from premenopausal women with GCBD diagnosed by clinical, xheromammographic, and cytological studies. After separation of cells for cytological evaluation, the cyst fluid was centrifuged and supernatant stored at -80A degrees C until the analysis. Sodium, potassium, calcium, phosphorus, and iron were measured using Roche Diagnostics commercial kits on Hitachi 747-200 autoanalyzer. Measurements of copper and zinc were performed by flame atomic absorption spectrophotometer on Shimadzu AAS 680. We found statistically significant higher K, lower Na, higher phosphorus concentrations, and lower Na/K ratios in type I cysts when compared with type II cysts' values. Median values of Na/K ratio in type I and in type II were 0.32 and 6.2, respectively. Higher Zn, Cu, and Fe concentrations with respect to median values were noted in type I cysts; higher [Na.Cu/K.Zn], [Na.Cu/K.Fe], and [Na.Zn/K.Fe] ratios were found in type II cysts. A significant negative correlation existed between Na/K and Cu, and a significant positive correlation between Na/K and Fe in type II cysts (r = -0.660, p = 0.007; r = 0.615, p = 0.014, respectively). We can conclude that the trace elements content of BCF, in addition to electrolytes, could be useful in classifying the breast cyst. Future studies in larger series are needed to confirm these data
Angiocentric Glioma: The Infiltrative Glioma with Ependymal Differentiation
Angiocentric glioma is an epileptogenic, infiltrative, low grade glial tumor, with ependymal and astrocytic differentiation, most commonly seen in young adults and the pediatric age group. Herein we report a case of 21-year-old male patient who presented with fever and pharmaco-resistant seizures. Computed tomography revealed an iso-dense mass lesion in the gyrus rectus of the left frontal lobe. On magnetic resonance imaging the mass was hyperintense on both T1- and T2-weighted images with no contrast enhancement. Histopathological examination revealed monomorphous tumor cells diffusely infiltrating the neuropil with circumferential, radial, or longitudinal angiocentric alignment and subpial aggregation with perpendicular alignment of the cells to the pial surface. Among central nervous system tumors with ependymal differentiation, this distinct entity is the one with an infiltrating growth pattern. In spite of the infiltrating pattern, it does not seem to have a potential for aggressive behavior
Metastatic tumors in the breast: a report of 5 cases and review of the literature.
Breast cancer is the most common malignacy in women. However metastases to the breast from non-mammary malignant neoplasms are rare and were detected at a rate of 0.28% in our series. Clinical and pathologic findings in 5 cases of metastatic tumors (malign mesenchymal tumor, squamous cell carcinoma of the tongue, non-Hodgkin lymphoma, and Sezary syndrome) in the breast are presented and discussed with respect to the literature. Detailed clinical history and a multidisciplinary approach are useful in establishing correct diagnosis and preventing unnecessary radical surgery
Alteration in the subcellular location of the inhibitor of growth protein p33(ING1b) in estrogen receptor alpha positive breast carcinoma cells
ING1 has regulatory roles in the expression of genes associated with proliferation, apoptosis, and senescence. p33(ING1b) is the most widely expressed isoform of the gene. Downregulation of its nuclear expression is involved in differentiation and pathogenesis in invasive breast carcinoma. Yet the mechanism(s) by which p33 nuclear targeting is regulated remains unknown. In this study, we analyzed human invasive breast carcinoma tissue samples by immunostaining with p33 and correlating p33 location with the presence of ERa. Our findings show the expression of p33 protein in ER alpha-positive tumor samples was in the nucleus alone, while the expression was mainly in the cytoplasm in ERa-negative tumor samples. Examination of the localization of p33 in the nucleus and/or cytoplasm in several different cell lines demonstrated 17 beta-estradiol (E2) treatment causes dramatic compartmental shift in p33 protein from the cytoplasm to the nucleus in ER alpha-positive MDA-66 cells. No significant differences in ER alpha-negative MDA-MB-231 cells in the same conditions were observed. We show for the first time nuclear localization of p33 is regulated by estradiol induction in ER alpha-positive breast cancer cells. These results suggest compartmental shift in p33 by ER signaling may be an important molecular event in the differentiation and pathogenesis of invasive breast cancer
Breast myxoma: Radiologic and histopathologic features.
Myxomas are benign mesenchymal tumors, which rarely develop in the breast. Histologically, stellate, round, and spindle-shaped cells with vesicular nuclei and scant cytoplasm are scattered in the myxoid stroma. We present a case of this rare type of breast tumor with sonographic and mammographic findings
Phyllodes tumor of the breast in an adolescent girl
Phyllodes tumor (PT) is an uncommon tumor in adolescent girls and young women. A case of PT in a 14-year-old girl is reported. The clinical examination showed a painless tumor that had grown during 10 months. Total excision of the mass with wide margin was performed. The diagnosis, behavior, and treatment of this rare tumor are discussed
