Neoadjuvant chemoradiation (CRT), tailored mesorectal excision, and intraoperative radiotherapy (IORT) have become the leading measures for rectal cancer treatment. The objective of this study was to evaluate early and long-term results of a multimodal treatment model for rectal cancer followed by curative surgery. Prospectively collected hospital records of 338 patients surgically treated for rectal cancer between January 1998 and December 2008 were retrospectively reviewed. Patients with high rectum level cancers and those with middle and low rectum cancers with clinical stage T1 to T2 underwent surgery, whereas those with T3 to T4 and N1 disease at the middle and low rectum received neoadjuvant CRT in 96.2 per cent of cases. Short-course neoadjuvant radiotherapy was not considered for neoadjuvant treatment. Postoperative major complications and mortality rates were 12.7 and 2.3 per cent, respectively. Overall 5-year disease-specific and disease-free survival were 80 and 73.1 per cent, respectively, whereas local recurrence rate was 6.1 per cent. At multivariate analysis, nodal status and circumferential margin status were independently associated with poor survival; local recurrence rates were independently affected by nodal and marginal status and tumor stage. The extent of mesorectal excision should be tailored depending on tumor location and the use of neoadjuvant chemotherapy, combined with IORT in advanced middle and low rectal cancer, leading to remarkable tumor downstaging with excellent prognosis in responding patients.

AbstractThe importance of total mesorectal excision (TME) has been the global standard of care in patients with rectal cancer. However, there is no universal strategy for lateral lymph nodes (LLN). The treatment of the lateral compartment remains controversial and has gone to the opposite directions between Eastern and Western countries in the past decades. In the East, mainly Japan, surgeons consider LLN metastases as regional disease and have performed TME with lateral lymph node dissection (LLND) without neoadjuvant (chemo)radiotherapy ([C]RT) in patients with clinical Stage II/III rectal cancer below the peritoneal reflection. In the West, neoadjuvant radiotherapy or has been the standard, and surgeons do not perform LLND assuming the (C)RT can sterilize most lateral lymph node metastasis (LLNM). Recent evidences show that lateral nodes are the major cause of local recurrence after (C)RT plus TME, and LLND reduces local recurrence particularly from the lateral compartment. Probably a combination of the two strategies, that is, neoadjuvant (C)RT plus LLND, would be needed to improve outcomes in patients with lateral nodal disease.

The purpose of the study was to evaluate the prognostic significance of carcinoerembryonic antigen in patients with rectal cancer and correlate its baseline with the degree of therapeutic pathomorphosis after neoadjuvant chemoradiotherapy.Materials and methods. An estimate of the informative value of carcinoerembryonic antigen (CEA) indices in 179 patients with colorectal cancer determined before and after preoperative chemoradiotherapy (CRT) in SOD 50 Gy.Results. Analysis of the results presented in the study showed that in all patients, CRT caused a significant decrease in the level of CEA (–71%) 10 weeks after its end (p < 0.001). In the course of the pathomorphological study, after the neoadjuvant treatment, the first degree of tumor pathomorphism was recorded in 4.5% of patients, II – 38.5%, III – 45%, IV – 12% (the degree of pathomorphosis is not related to the clinical stage and the degree of differentiation of colorectal cancer). It was revealed that patients with III and IV degrees of therapeutic pathomorphosis initially had a CEA level lower, in comparison with patients with grade I-II. Clinical progression of the disease is diagnosed in 24% of cases (43/179). It was noted that in patients with the IV degree of therapeutic pathomorphism of the tumor, no recurrence of the rectal cancer was detected in either case.Conclusion. The results of the study showed that the problem of individual prediction of the effectiveness of combined treatment of the rectal cancer remains very relevant, rather complicated and yet not completely solved. However, it can be assumed that the use of such an indicator as CEA in monitoring patients after the treatment, can serve as a criterion for the sensitivity of colorectal cancer to CRT. Initially low antigen level can be considered as a positive factor of tumor response to ongoing treatment and disease-free survival of patients with locally advanced rectal cancer.

758 Background: A standard therapy for locally advanced rectal cancer (LARC) includes fluoropyrimidine (FP)-based neoadjuvant chemoradiation (nCRT). Previous studies have inconsistently demonstrated that baseline neutrophil- and platelet-to-lymphocyte ratios (NLR and PLR) are predictive of response to nCRT or prognostic of outcomes in LARC. Methods: We performed a review of patients with LARC undergoing nCRT followed by surgery with curative intent from 2005-2013 in 3 academic cancer centers from 2 Canadian provinces. Data regarding demographics, staging, baseline hematologic variables (<4 weeks prior/up to 2 weeks after initiating nCRT) and treatment details were collected. Outcome measures of interest were pathological complete response (pCR), disease-free survival (DFS) and overall survival (OS). Logistic regression and Cox proportional hazard models were used to assess for an association between baseline hematologic variables and outcomes. Results: Of 1081 identified patients, 845 were included in the DFS/OS analysis. Median age was 61 (range 23-87), 70% male, 85% performance status (PS) 0-1. 31% and 67% had clinical stage II and III disease, respectively. 25% had elevated NLR (≥ 4), and 64% had elevated PLR (≥ 150). 98% of patients received FP-based nCRT, with 96% receiving ≥ 44 Gy (median 50 Gy [range 20-74]). 80% completed neoadjuvant chemotherapy and 94% completed neoadjuvant radiotherapy, with a pCR rate of 23%. After a median follow up time of 64 months, 6% developed local recurrence, 20% developed distant recurrence and 19% have died. 5-year OS and DFS were 78% (95% CI 74-81%) and 76% (95% CI 73-79%), respectively. In multivariate analyses, elevated baseline NLR and PLR were not prognostic for OS or DFS. Elevated NLR was a negative predictor of pCR (OR 0.61, p=0.037, 95% CI 0.38-0.97); there was no association with elevated PLR. Conclusions: Elevated NLR was a negative predictor of pCR, but not prognostic for DFS and OS. PLR was neither predictive nor prognostic.

Abstract Objective Transanal total mesorectal excision (taTME) is an alternative to conventional TME owing to its reported superior ability to achieve clear resection margins in low rectal cancers. Yet, nationwide Norwegian data claimed a 12-month local recurrence rate of up to 10%, a three-fold increase compared to conventional TME, questioning the oncological safety of taTME. Methods Consecutive patients with low rectal cancer treated by taTME were prospectively included. Patients who required a partial mesorectal excision were excluded. Perioperative outcomes were reported as median and interquartile range (IQR). Data were independently audited and certified. Results 125 patients (88 men : 37 women) with a low rectal cancer (7 cm to anal verge, IQR 5-9) underwent a taTME. Age and body mass index were 65 years (IQR 56-76) and 26 kg/m2 (IQR 23-29). 87 (70%) patients had neoadjuvant radiochemotherapy. Surgery time was 357 minutes (IQR 303-435), including an ileostomy in all patients. 1 patient (0.8%) required a conversion to laparotomy. Performing taTME in a 2-team technique saved 94 minutes or 19% operating time (p &lt; 0.005, t-test one-team (n = 52, 420 minutes, IQR 349-494) vs. 2-team (n = 73, 326 minutes, IQR 285-372). 30-day morbidity amounted to 36% minor complications (Dindo Clavien I-II) and 25% major complications (Dindo Clavien III-V), including 11 anastomotic leaks (9%) and 3 reoperations (3%). Most of the leaks could be managed endoscopically and the ileostomy reversed at last. Median length of hospital stay was 10 days (IQR 8-14). Median follow-up was 45 months (IQR 25-67; range 13-95). Dissection of the mesorectum was excellent (Quirke 1 incomplete mesorectal excision rate: 1.6%) with 100% clear margins (distal margin 16mm, IQR 10-30; circumferential margin 10mm, IQR 5-15). Median T stage was 3 (IQR 2-3). 24 patients had positive lymphnodes (median 27, IQR 21-38). Local recurrence occurred in 7 (6%) patients and development of metachronous metastasis was present in 36 (29%) patients. This led to a 5-year disease-free survival of 56% and a 5-year overall survival of 86%. Conclusion Transanal total mesorectal excision allows good surgical and oncologic quality to the expenses of a reasonable surgery time and morbidity.
