Selected AbstractsUSEFUL ENDOSCOPIC ULTRASONOGRAPHY TO ASSESS THE EFFICACY OF NEOADJUVANT THERAPY FOR ADVANCED ESOPHAGEAL CARCINOMA: BASED ON THE RESPONSE EVALUATION CRITERIA IN SOLID TUMORSDIGESTIVE ENDOSCOPY, Issue 1 2005Masaho Ota Objective:, The aim of the present study was to assess the usefulness of endoscopic ultrasonography (EUS) for evaluating the efficacy of neoadjuvant therapy for advanced esophageal carcinoma based on the Response Evaluation Criteria in Solid Tumors (RECIST). Patients and Methods:, Sixty-two patients with advanced esophageal carcinoma underwent surgical resection after neoadjuvant therapy. The maximal tumor thickness was measured by EUS before and after neoadjuvant therapy, and the percent reduction was compared with the pathological response. Based on the RECIST, PD-SD (progressive disease-stable disease) was defined as < 30% reduction of tumor thickness on EUS, PR (partial response) as , 30% reduction of tumor thickness, and CR (complete response) as no detectable tumor (100%). Results:, The percent reduction of the thickness of Grade 0,1, Grade 2 and Grade 3 tumor was 11.5 ± 21.0%, 48.2 ± 17.0% and 74.9 ± 21.1%, respectively. There were significant differences in the extent of reduction among the three groups. Based on the RECIST, 80% of Grade 0,1 cases, 91% of Grade 2 cases and 22% of Grade 3 cases were PD-SD, PR, and CR according to EUS, respectively. EUS correctly identified 80% of non-responders and 94% of responders. Conclusions:, The percentage reduction of tumor thickness on EUS closely reflected the pathological evaluation. EUS evaluation based on the RECIST seems to be useful for monitoring neoadjuvant therapy in patients with esophageal carcinoma. [source] Long-term outcome of endoscopic biopsy and subsequent nephroureterectomy for upper urinary tract tumorINTERNATIONAL JOURNAL OF UROLOGY, Issue 1 2001Shigeru Minowada Abstract Background: Upper urinary tract tumors can be biopsied using a flexible ureterorenoscope. This study examined retrospectively possible adverse effects of this procedure on patient outcome. Methods: The study subjects consisted of 16 consecutive patients with renal pelvic tumor (n = 13) and upper ureteral tumor (n = 3). All subjects underwent endoscopic biopsy of their tumor and subsequent total nephroureterectomy between 1989 and 1995. The follow-up period ranged from 4.1 to 9.5 (mean 5.2) years. Results: The overall 5-year survival rate was 87.0%, being 100% in 12 patients with tumors of grade 1 or 2. In contrast, of four patients with grade 3 tumor, three (75%) developed systemic lymphogenous and/or multiple lung metastases within 1 year postoperatively. Conclusions: The excellent patient outcomes deny any adverse effect of endoscopic biopsy on patients with grade 1 or 2 tumor. However, the endoscopic procedure should be performed prudently when a high grade tumor is suspected. [source] Prognostic value of lymph node ratio in poor prognosis node-positive breast cancer patients in Saudi ArabiaASIA-PACIFIC JOURNAL OF CLINICAL ONCOLOGY, Issue 2 2010Ezzeldin M IBRAHIM Abstract Aim: Women in Saudi Arabia develop breast cancer at a young age with high prevalence of poor prognostic features. Because of such features, it is necessary to examine prognostic factors in this population. One such factor is the prognostic role of lymph node ratio (LNR). Methods: We performed retrospective analyses of patients with invasive non-metastatic breast cancer who underwent axillary lymph node dissection and had one or more positive axillary lymph nodes. Results: Two hundred and seventeen patients were considered eligible for the analysis. The median age was 46 years. At a median follow-up of 39.8 months, the median disease-free survival (DFS) was 67.3 months (95% CI, 50.4 to 84.3 months). Neither the classification of patients based on positive lymph node (pN) staging system, nor the absolute number of pN prognosticated DFS. Conversely, age , 35 years at diagnosis, grade 3 tumors and the intermediate (>0.20 to ,0.65) and high (>0.65) LNR categories were the only variables that were independently associated with adverse DFS. Using these variables in a prognostic model allowed the classification of patients into three distinctive risk strata. The overall survival (OS) in this series was 92.5 months (95% CI, 92.1,92.6). Only ER negative tumor adversely influenced OS. Conclusion: Analysis of survival outcome of mostly young patients with early breast cancer identified adverse prognostic variables affecting DFS. If the utility of the derived model including LNR is proven in a larger patient population, it may replace the use of absolute number of positive axillary lymph nodes. [source] Locoregional recurrence of triple-negative breast cancer after breast-conserving surgery and radiation,,CANCER, Issue 5 2009Gary M. Freedman MD Abstract BACKGROUND: The results of radiation on the local control of triple receptor-negative breast cancer (negative estrogen [ER], progesterone [PR], and HER-2/neu receptors) was studied. METHODS: Conservative surgery and radiation were used in 753 patients with T1-T2 breast cancer. Three groups were defined by receptor status: Group 1: ER or PR (+); Group 2: ER and PR (,) but HER-2 (+); and Group 3: triple-negative (TN). Factors analyzed were age, menopausal status, race, stage, tumor size, lymph node status, presentation, grade, extensive in situ disease, margins, and systemic therapy. The primary endpoint was 5-year locoregional recurrence (LRR) isolated or total with distant metastases. RESULTS: ER- and PR-negative patients were statistically significantly more likely to be black, have T2 disease, have tumors detectable on both mammography and physical examination, have grade 3 tumors, and receive chemotherapy. There were no significant differences noted with regard to ER, and PR, patients by HER-2 status. There was a significant difference noted in rates of first distant metastases (3%, 12%, and 7% for Groups 1, 2, and 3, respectively; P = .009). However, the isolated 5-year LRR was not significantly different (2.3%, 4.6%, and 3.2%, respectively; P = .36) between the 3 groups. CONCLUSIONS: Patients with TN breast cancer do not appear to be at a significantly increased risk for isolated LRR at 5 years and therefore remain appropriate candidates for breast conservation.

[source] Clinicopathologic characteristics and prognostic factors in 420 metastatic breast cancer patients with central nervous system metastasisCANCER, Issue 12 2007Kadri Altundag MD Abstract BACKGROUND. Breast cancer is the second most common cause of central nervous system (CNS) metastases. Several risk factors for CNS metastases have been reported. The objective of the current study was to describe clinicopathologic characteristics and prognostic factors in breast cancer patients with CNS metastases. METHODS. The authors retrospectively evaluated clinical data from 420 patients who had been diagnosed with breast cancer and CNS metastasis between 1994 and 2004 at the University of Texas M. D. Anderson Cancer Center. RESULTS. The median age of the patients at the time of diagnosis of breast cancer was 45 years (range, 25,77 years). Premenopausal and postmenopausal patients were distributed equally. Most patients had invasive ductal histology (91.2%), grade 3 tumors (81.4%) (using the modified Black nuclear grading system), T2 tumor classification (40.1%), and N1 lymph node status (59.7%) diagnosis. Forty percent of patients had estrogen receptor (ER)-positive disease, and 34% had progesterone receptor-positive disease. HER-2/neu status was recorded for only 248 patients, and 39% of the patients in that group had HER-2/neu -positive disease. The most common sites of first metastasis were liver, bone, and lung. CNS metastasis was the site of first recurrence in 53 patients (12%). In total, 329 patients had received either neoadjuvant treatment (113 patients) or adjuvant chemotherapy (216 patients). The majority of those patients (74.4%) had received anthracycline-based regimens. Metastasis was solitary in 111 patients (26.4%), and 29 patients had only leptomeningeal metastases. The median time from breast cancer diagnosis to CNS metastasis was 30.9 months (range, from ,5 months to 216.7 months). The median follow-up after a diagnosis of CNS metastasis was 6 months (range, 7,95.9 months). In all, 359 patients died, and the overall median survival was 6.8 months. Only age at diagnosis and ER status were associated significantly with overall survival in the multivariate analysis. CONCLUSIONS. The current results indicated that the prognosis remains patients with breast cancer metastatic to the CNS. More effective treatment approaches are needed for patients with CNS metastases, even for those with favorable prognostic factors, such as ER-positive tumors or younger age.
