14601 Continued efforts to improve local control and to maximize sphincter preservation in patients with rectal carcinoma led to consideration of preoperative chemoradiation. The purpose of this retrospective study is to examine clinical outcomes and find out which prognostic factors are related to survival in patients treated with neoadjuvant chemoradiation in Sparrow Hospital from 1998–2003. Forty two patients with biopsy proven rectal carcinoma without evidence of extra pelvic spread were treated in this fashion. Radiation therapy was administered for a total dose of 5.00 cGy. Chemotherapy used was 5-FU in 37 patients, and in combination with leucovorin in additional 5 patients. Surgical treatments performed were abdominoperineal resection (23 pts), low anterior resection in 13 pts., transanal excisions (2 pts), 2 patients had only exploratory laparotomy and for 2 patients records were not available. Cox proportional hazards regression techniques were used to estimate survival rates. Univariate and multivariate Cox proportional hazards analyses were used to evaluate relationship between risk factors and the survival. The SAS system (V9.1.3, Cary NC) was used for all analyses. Out of 42 patients analyzed 25 were males and 17 females. Mean age was 65 years (range 31 - 85). Median follow-up time was 57 months with a range from 7 to 98 months. After the surgery 4 patients had complete response, 12 were stage I, 10 stage II, 12 patients stage III, one patient had metastatic disease and for 2 patients records were inadequate. Analysis of disease free survival showed actuarial 5-year disease free survival to be 59%. Actuarial 5-year overall survival was 67%. Median overall survival was still not reached, while median disease-free survival is 78 months . Univariate and multivariate analyses showed that only postoperative stage was associated significantly with overall survival. Specifically, there was an increase in the risk of mortality of just over 3-fold for each increment in post-operative stage. In conclusion, in the community settings preoperative chemoradiation seem to provide good overall and disease free survival for patients with rectal cancer. Postoperative stage appears to be the most important prognostic factor for the survival. No significant financial relationships to disclose.

Background. The objective of this study was to explore the role of preoperative fibrinogen-to-prealbumin ratio (FPR) in evaluating the prognosis of patients with stage I–III colorectal cancer (CRC). Methods. This retrospective study enrolled 584 stage I–III CRC patients undergoing surgical resection. Logistic regression analysis was used to explore the correlation between FPR and postoperative complications. The Kaplan-Meier curve and Cox proportional hazards model were used to identify the prognostic factors. The nomograms were constructed based on the prognostic factors. The concordance index and calibration curve were used to determine the accuracy of the nomograms. Time-dependent receiver operating characteristic was used to compare the predictive prognostic efficacy of nomograms and TNM stage. Results. FPR was determined to be an independent factor affecting postoperative complications. Patients with a low-FPR had a significantly better prognosis than those with a high-FPR (disease-free survival, p = 0.028 ; overall survival, p = 0.027 ), especially patients with stage I CRC (disease-free survival, p = 0.015 ; overall survival, p = 0.017 ). The Cox proportional hazards model identified FPR as an independent poor prognostic factor of disease-free survival (hazard ratio HR = 1.459 , 95% confidence interval CI = 1.074 –1.954, p = 0.011 ) and overall survival ( HR = 1.405 , 95% CI = 1.034 –1.909, p = 0.030 ). The prognostic nomograms had good accuracy and were superior to the traditional TNM stage. Conclusions. FPR is a potential indicator for predicting short- and long-term prognosis of stage I–III CRC patients undergoing surgical resection.

Abstract Background The aim of this study is to compare the outcome of patients with adenocarcinoma of the distal oesophagus (AEG Type I) treated with perioperative chemotherapy or neoadjuvant chemoradiation. Methods A retrospective analysis of eligible patients from four Austrian centers was conducted. All patients with AEG type I treated between January 2007 and October 2017 with chemotherapy (EOX-protocol) or chemoradiation (CROSS-protocol, or 5-FU/Cisplatin), followed by oesophagectomy were included in the study. Primary outcomes overall survival, and disease free survival as well as secondary outcomes, achievement of pathological complete response pCR (ypT0N0M0) or downstaging of T- or N-stage were analyzed. Primary outcomes were calculated by the Kaplan-Meier-method. Results Data of 117 patients were analyzed, 59 received chemoradiation (50/59 CROSS and 9/59 5-FU/Cisplatin) and 58 patients received perioperative chemotherapy (EOX). Complete data at time of submission were available in 40 patients in the chemoradiation group and in 37 patients in the chemotherapy group. The median follow-up time in the chemoradiation group was 13,0 months (CI 95%: 11,0–15,0) and in the chemotherapy group 45,0 months (CI 95%: 28,8–61,3). Overall survival rate in the EOX group after ½, 1, 3 and 5 years was 92%, 83%, 63% and 34%. So far long term data are not available after chemoradiation, after ½ year overall survival was 84% and after one year 60%. Disease free survival rate in the EOX group after ½, 1, 3 and 5 years was 91%, 81%, 54% and 32%, in the chemoradiation group after ½ and one year 80% and 50%. A significant difference was found in the pathological complete response (pCR) rate, it was achieved in 19% of patients after chemoradiation and in 3% after chemotherapy (P = 0000). Conclusion Concerning major response of the primary tumor there are clear advantages for chemoradiation. In regards to systemic tumor control there seems a tendency in favor for chemotherapy.

Abstract Background In order to identify the characteristics and factors affecting the treatment and prognosis of primary fallopian tube cancer(PFTC),we analyzed the clinical profile of PFTC in the past 10 years in our hospital, which is center in Western China. Methods A retrospective analysis was performed on 57 patients diagnosed as PFTC at the Department of Obstetrics and Gynecology, the First Affiliated Hospital of Xi’an Jiaotong University from past ten years. The clinical index and a Cox proportional hazards model was used for univariate and multivariate survival analyses. Results The mean age of PFTC at diagnosis was 57.35±9.01 years. Palpable pelvic and/or abdominal mass (68.4%) was the main clinical symptom. Preoperatively, 80.7% patients were misdiagnosed with ovarian cancer, and 43.8% of patients were at stage III. 26 patients were relapsed at the median of 18.5 (3-83) months. The 5-year overall survival (OS) rate was 15.4%, and the 5-year disease-free survival (DFS) was 11.5%. Additionally, univariate analysis showed that tumor stage and size of residual tumor were both related to 5-year OS and DFS. While level of serum carbohydrate antigen 125(CA125) pre-treatment was only related to DFS. The Cox proportional hazards model demonstrated that residual tumor size was the only independent factor related to both 5-year OS and DFS. Conclusions PFTC is a more common malignancy at post-menopause stage in women. The symptoms are not typical in most case and often diagnose at late clinical stage. Tumor stage, level of CA125, and residual lesion size affected the disease-free survival or/ and overall survival. Trial registration Not applicable.

Objective: To determine whether shear-wave elastography (SWE)-measured tumor stiffness is associated with disease-free survival in females with early-stage invasive breast cancer. Methods: This retrospective study included 202 consecutive females (mean age, 52.9 years; range, 25–84 years) with newly diagnosed T1–two breast cancer who underwent preoperative SWE between April 2015 and January 2016. Tumor stiffness was assessed and quantitative SWE features of each breast lesion were obtained by a breast radiologist. Cox proportional hazards models were used to identify associations between SWE features and disease-free survival after adjusting for clinicopathologic factors. Results: Fifteen (7.4%) patients exhibited recurrence after a median follow-up of 56 months. Mean (Emean), minimum, and maximum elasticity values were higher in females with recurrence than in those without recurrence (184.4, 138.3, and 210.5 kPa vs 134.9, 101.7, and 163.6 kPa, respectively; p = 0.005, p = 0.005, and p = 0.012, respectively). Receiver operating characteristics curve analysis for prediction of recurrence showed that Emean yielded the largest area under the curve (0.717) among the quantitative SWE parameters, and the optimal cut-off value was 121.7 kPa. Multivariable Cox proportional hazards analysis revealed that higher Emean (>121.7 kPa) [adjusted hazard ratio (HR), 10.01; 95% CI: 1.31–76.33; p = 0.026] and lymphovascular invasion (adjusted HR, 7.72; 95% CI: 1.74–34.26; p = 0.007) were associated with worse disease-free survival outcomes. Conclusion: Higher SWE-measured Emean was associated with worse disease-free survival in females with early-stage invasive breast cancer. Advances in knowledge: Tumor stiffness assessed with shear-wave elastography might serve as a quantitative imaging biomarker of disease-free survival in females with T1–two breast cancer.
