RESUMO

OBJECTIVE: The aim of this study is to investigate if there was a change in time in terms of age at diagnosis, menopausal status, pathologic tumor size, lymphatic metastasis and pathologic stage in patients with surgical treatment for breast carcinoma. MATERIAL AND METHODS: The clinical and pathological characteristics of 1223 patients with breast carcinoma who underwent surgical treatment between January 1994 and December 1998, and of 1346 patients who underwent surgical treatment with the same diagnosis between January 2004 and December 2008 were retrospectively reviewed. RESULTS: The median age at diagnosis was 48 (20-78) years during the first period, and 50 (20-91) years during the second period. While 27% of patients were 40 years of age or younger in the first period, this ratio decreased to 20% during the second period (p=0.0001). The rate of premenopausal patients was 54% in the first period and 46% in the second period (p=0.0001). The median tumor size at diagnosis was 3 cm at the first period, and 2.5 cm at the second period. The number of patients with tumor size ≤2 cm increased in time from 391 (32%) to 531 (39%) (p=0.0001). Among young patients (aged ≤40 years), the number of patients with tumor size 2 cm or smaller were 81 (24.5%) and 92 (33.8%) at the first and second periods, respectively (p=0.001). Lymphatic metastases rate of patients aged ≤40 years was higher than patients aged >40 years, in both study periods (p=0.0001). The number of patients staged as pN1 at the first period increased from 356 (50.8%) to 441 (56.3%) at the second interval, while those staged as pN3 decreased from 251 (35.8%) to 175 (22.3%) (p=0.0001). CONCLUSION: It may be concluded that recently, breast cancer is diagnosed at older ages, the rate of young and premenopausal patients and size on diagnosis has decreased, and breast-conserving surgery is used more often.

RESUMO

OBJECTIVE: Anal squamous cell carcinomas are one of the rare cancer types. Due to the developments in the past 35 years, surgery is no longer the first treatment of choice. The aim of this study was to retrospectively examine the outcomes of 24 patients treated in a single center in the last 21 years in terms of applied treatment, local relapse, distant metastasis, post-treatment complications, and survival. MATERIAL AND METHODS: Data obtained from 24 anal squamous cell carcinoma patients, who were treated in Ankara Oncology Research and Education Hospital between 1990 and 2010, were retrospectively evaluated. RESULTS: Of the 24 patients, 16 had anal canal squamous cell carcinoma and eight had perianal squamous cell carcinoma. All of the patients with anal canal squamous cell carcinoma (n=16) received chemoradiotherapy. Three of these patients who did not respond to treatment, underwent abdominoperineal resection. The patients with perianal squamous cell tumors were treated by local excision. During the follow -ups, seven patients experienced local relapse, and one patient had distant organ metastasis. Only one patient died. Five-year disease free survival rate was found as 66%. CONCLUSION: Our findings suggest that the first alternative in the treatment of anal squamous cell tumors should be chemoradiotherapy; and surgery seems to be the appropriate approach for the non-responsive and relapsing cases.

RESUMO

Phosphodiesterases (PDEs) are enzymes primarily responsible for regulation of the intracellular cyclic nucleotides. Among these enzymes, the type 4 PDE is highly expressed in most immune and inflammatory cells and its inhibition causes the suppression of immune and inflammatory cell activity, including production of cytokines. This study was designed to investigate the efficacy of the type 4 PDE inhibitor rolipram on acute pancreatitis in rats. Rats were divided into three groups--treatment, control, and sham. In the treatment and control groups, rats were pretreated with rolipram and vehicle before acute pancreatitis was induced. The pretreatment of rats with rolipram significantly reduced the amylase (P<0.0001) and IL-1ß levels (P=0.002) compared to vehicle treated rats. Also, mean histopathological scores were significantly reduced by rolipram treatment (P<0.005). It can be concluded that rolipram ameliorates severity of pancreatitis in rats.

RESUMO

BACKGROUND: The presence of extranodal invasion (ENI) in the metastatic lymph nodes is reported to increase the risk of locoregional recurrence while shortening disease-free and overall survival in patients with breast cancer. In this study the relationship between ENI and other prognostic parameters and survival is investigated. METHODS: Of 650 patients with breast cancer who were treated in Ankara Oncology Teaching and Research Hospital from 1996 to 2003, 368 (56.6%) had lymph node metastasis. The patients with axillary metastasis were separated into two groups as with and without invasion to lymph node capsule and the surrounding adipose tissue. Clinicopathologic features were analyzed by univariate and multivariate logistic regression. RESULTS: Of 368 patients with axillary metastasis, 135 (36.7%) had ENI. Based on multivariate analysis; the number of metastatic lymph nodes, lymphatic invasion, and tumor necrosis were found to be related with ENI. In the group with ENI, 5-year overall survival rate was 74.8%, compared to 82.3% for patients without ENI which was significantly lower (P = 0.04). CONCLUSIONS: In lymph node positive breast cancer with presence of ENI, adverse prognostic parameters are more frequently encountered and has a worse overall survival compared to group without ENI.
