Purpose The prognostic relevance of preoperative high-resolution magnetic resonance imaging (MRI) assessment of circumferential resection margin (CRM) involvement is unknown. This follow-up study of 374 patients with rectal cancer reports the relationship between preoperative MRI assessment of CRM staging, American Joint Committee on Cancer (AJCC) TNM stage, and clinical variables with overall survival (OS), disease-free survival (DFS), and time to local recurrence (LR). Patients and Methods Patients underwent protocol high-resolution pelvic MRI. Tumor distance to the mesorectal fascia of ≤ 1 mm was recorded as an MRI-involved CRM. A Cox proportional hazards model was used in multivariate analysis to determine the relationship of MRI assessment of CRM to survivorship after adjusting for preoperative covariates. Results Surviving patients were followed for a median of 62 months. The 5-year OS was 62.2% in patients with MRI-clear CRM compared with 42.2% in patients with MRI-involved CRM with a hazard ratio (HR) of 1.97 (95% CI, 1.27 to 3.04; P < .01). The 5-year DFS was 67.2% (95% CI, 61.4% to 73%) for MRI-clear CRM compared with 47.3% (95% CI, 33.7% to 60.9%) for MRI-involved CRM with an HR of 1.65 (95% CI, 1.01 to 2.69; P < .05). Local recurrence HR for MRI-involved CRM was 3.50 (95% CI, 1.53 to 8.00; P < .05). MRI-involved CRM was the only preoperative staging parameter that remained significant for OS, DFS, and LR on multivariate analysis. Conclusion High-resolution MRI preoperative assessment of CRM status is superior to AJCC TNM–based criteria for assessing risk of LR, DFS, and OS. Furthermore, MRI CRM involvement is significantly associated with distant metastatic disease; therefore, colorectal cancer teams could intensify treatment and follow-up accordingly to improve survival outcomes.

Abstract Aim The utility of Circumferential Resection Margin (CRM) status in predicting prognosis in oesophageal cancer remains controversial, with two different definitions of a positive CRM, one from the College of American Pathologists (CAP) (tumour at margin) and the other from the Royal College of Pathologists (RCP) (tumour within 1 mm)1-3. This study aimed to analyze the validity of these definitions in oesophageal tumours and explore the optimal cutoff value for CRM to predict survival. Background & Methods Patients who underwent curative radical oesophageal resection for locally advanced (>pT2) adenocarcinoma or squamous cell carcinoma of the oesophagus were selected from 2007 to 2016. Patients with positive longitudinal resection margins were excluded. CRM was histologically reassessed using an ocular micrometer. Overall survival (OS) and disease-free survival (DFS) were estimated with uni and multivariate analyses. Results From 860 resected patients, 283 fulfilling the inclusion criteria were selected. CRM was measured as follows: CRM=0mm (n=48), 0<CRM ≤1mm (n=123) and CRM>1mm (n=112). In univariate (figure 1) and multivariate analysis R1 resection, according to both definitions was significantly associated with poor OS (CAP: HR=2.26,p<0.001; RCP: HR=1.42,p=0.035). However only CAP definition accurately predicted DFS (CAP: HR=2.25,p<0.001; RCP: HR=1.28,p=0.094). When comparing the 3 CRM groups and taking 0 < CRM ≤1mm as reference, only CRM=0 predicted OS and DFS (p<0.001). A CRM cutoff at 0.1 mm was the best to predict OS and differed according to histology. Conclusion Among existing definitions of CRM, CAP definition was more accurate to predict prognosis and recurrence. New cutoffs are promising.

In the period 01.01.1991 - 12.31.1996, 523 operations due to rectal carcinoma were performed on the First Surgical Clinic, the Third Department for Colorectal Surgery. Most common localization of tumor was in the distal third of the rectum 65,2%. In the middle third, there were 28,9% and in the upper, intraperitoneal third 5,9%. We performed 286 low anterior stapled resections, 93 anterior resections with hand-sewn anastomosis and 144 Abdominoperineal excisions of rectum (Miles procedure). Pathohistological examination revealed adenocarcinoma in all cases. In this study we analyzed local recurrence and five-year survival after long-term follow-up in the group where Miles procedure was carried out as a potentially curative procedure (except 4,9% cased with Dukes D stage). There were 74,3% males and 23,7% females median age 59,2 years. According to Dukes classification there were 4,9% in stage A, 47,2% in stage B, 43,1% stage C, and 4,9% stage D. There were 4 (2,7%) postoperative deaths. Recurrence of the disease was registered in 44 (30,5%) patients. Local recurrence alone was found in 14 (9,7%) patients, while distant spread was registered in 30 (20,8%) patients. At present, the median follow-up is at 72,9 months. Analysis by the Kaplan-Meier's test shows cumulative survival of 61%, and disease free survival of 63,4% at 60 months of the follow-up. Dukes C is associated with a very poor prognosis; sur-M\al after 60 months of follow up shows cumulative Survival of 0,35 while Dukes B has far better prognosis (0,86). Analysis of disease free survival by Dukes stage shows that Dukes C has the worst prognosis (disease free survival 0,36 after 60 months), while stage B has much better prognosis (0,84). Local recurrence analysis by the Kaplan-Meier's test shows disease free survival of 84,9% at 60 months of follow-up. Analysis of local recurrence by Dukes stage shows 1,00% disease free survival for cases in stage A, 0,94 for Dukes B and 0,66 for Dukes C, while overall comparison between groups regarding local recurrence using the Wilcoxon (Gehan) statistic shows statistically significant difference (p=0,005). There is no statistical difference between Dukes A and Dukes B cases in distribution of local recurrence.

Background: The relationship between neutrophil-lymphocyte ratio (NLR) with outcome is a complex issue. A high NLR reflects systemic inflammation. This study aimed to estimate the relationship between NLR, and platelet-lymphocyte ratio (PLR) in disease-free survival (DFS). Methods: This was a cross-sectional study in which we reviewed the patient files of 102 patients with breast cancer treated at the Babylon Oncology Center from January 2009 to September 2014, who had follow-up for at least 36 months. The following data were collected from patient files: age, diagnosis date, date of recurrence and/or metastasis, follow-up, histological tumor type, tumor size, node metastasis stage, histological differentiation degree, estrogen and/or progesterone receptor expression, HER2 neu status, and metastasis site. Results: The mean age of patients was 50.4 ± 11.7 years and lowest period of follow up was 40 months. Longest DFS was 62 months, with 5 years DFS in 52.5% of patients. Stage N0 was associated with a significantly higher DFS compared to stage N1. Isolated local recurrence was seen in 15% of patients and combined local recurrences with distant metastasis was observed 37%. NLR had the highest discrimination ability to predict recurrence and distant metastasis. Conclusion: An increase in NLR was associated with poor DFS, and it can therefore be a predictive and prognostic factor. NLR’s established prediction model warrants further investigation.

Objective: We assessed the pattern of local recurrence after salvagecryoablation of the prostate, and the impact of local recurrence onintermediate-term outcome.Methods: One hundred twenty-two patients who underwentsalvage cryoablation were studied after a mean follow-up of 56months. Serial prostate biopsy was carried out after cryoablation.The histopathology of prostate biopsies before and after cryoablationwere compared. The prognostic value of post-cryoablationbiopsy was assessed with the Cox regression method.Results: 23.1% of patients had a positive biopsy for prostate cancerfollowing salvage cryoablation. Most cancer recurrences occurredin the apex (51.5%), base (21.2%) and seminal vesicles (18.2%).The presence of cancer at the base of the prostate was found tobe a prognostic factor for eventual biochemical failure. Overall5-year biochemical disease-free survival (bDFS) was 28%, howeverpatients with cancer at the base of the prostate had a 5-yearbDFS of 0%.Conclusion: Cancer recurrences occurred in areas where aggressivefreezing was avoided as it might result in serious problems (e.g.,urethro-rectal fistula and incontinence). Post-cryoablation biopsiesand the location of persistent disease are of prognostic value.

Abstract Background Transanal total mesorectal excision (TaTME) for mid and low rectal cancer has been shown to improve short-term outcomes, mostly due to lower conversion rates and with improved quality of the specimen. However, robust long-term oncological data supporting the encouraging clinical and pathological outcomes are lacking. Methods All consecutive patients undergoing TaTME with curative intent for mid or low rectal cancer in two referral centers in The Netherlands between January 2012 and April 2016 with a complete and minimum follow-up of 36 months were included. The primary outcome was local recurrence rate. Secondary outcomes were disease-free survival, overall survival and development of metastasis. Results There were 159 consecutive patients. Their mean age was 66.9 (10.2) years and 66.7% of all patients were men. Pathological analysis showed a complete mesorectum in 139 patients (87.4%), nearly complete in 16 (10.1%) and an incomplete mesorectum in 4 (2.5%). There was involvement of the CRM (< 1 mm) in one patient (0.6%) and no patients had involvement of the distal margin (< 5 mm). Final postoperative staging after neoadjuvant therapy was stage 0 in 11 patients (6.9%), stage I in 73 (45.9%), stage II in 31 (19.5%), stage III in 37 (23.3%) and stage IV in 7 (4.4%). The 3-year local recurrence rate was 2.0% and the 5-year local recurrence rate was 4.0%. Median time to local recurrence was 19.2 months. Distant metastases were found in 22 (13.8%) patients and were diagnosed after a median of 6.9 months (range 1.1–50.4) months. Disease-free survival was 92% at 3 years and 81% at 5 years. Overall survival was 83.6% at 3 years and 77.3% at 5 years. Conclusions The long-term follow-up of the current cohort confirms the oncological safety and feasibility of TaTME in two high volume referral centers for rectal carcinoma. However, further robust and audited data must confirm current findings before widespread implementation of TaTME.

Background: Management of rectal cancer has been evolved over the past two decades with the introduction of total mesorectal excision (TME) and laparoscopic resection. Objective: This study aims to assess the difference in the long term outcomes after laparoscopic and open resection for potentially curable, non-metastatic rectal cancer patients.Methods: This is a retrospective study which has been conducted in a single tertiary care center where the patients were recruited from the colorectal database of the Section of Colon and Rectal Surgery at King Faisal Specialist Hospital & Research Centre (KFSH&RC). It included all the patients who had non-metastatic rectal cancer and underwent laparoscopic or open curative resection regardless of their age or the comorbid status during the period from January 2012 – December 2015. We studied the long-term outcomes for those patients which included the completeness of resection of the tumor, overall 3-year survival, 3-year disease free survival, local recurrence and distal recurrence of the cancer.Results:120 patients were included in this study, 69 of them were males and 51 were females. 86 (71.7%) of them underwent open surgery while 34 (28.3%) underwent laparoscopic surgery. After a mean follow up of 32.4 months: 104 patients were alive, 7 deceased and 9 were lost of follow up. Local recurrence in the open approach (OA), and laparoscopic approach (LA) groups was 3/86 (3.5%) and 4/34 (11.8%) respectively. Distal recurrence occurred in 12/86 (14%) of OA and 5/34 (14.7%) of LA. Overall 3-years survival for OA and LA was 89% and 97% respectively and the 3-years disease free survival was 49% and 57% respectively.Conclusion: Laparoscopic and open rectal excision were similar in their outcome.

AbstractBackground:Olfactory neuroblastoma is a rare sinonasal malignancy, with poorly defined treatment protocols. Management at a tertiary centre was retrospectively evaluated to inform future treatment and follow up.Methods:Cases treated with curative intent (2000–2014) were included. Data were collected, and overall and disease-free survival rates were calculated.Results:Eleven cases were identified, with a median follow up of 87 months. One patient was Kadish stage A, one was stage B, eight were stage C and one was stage D. The latter patient underwent chemoradiotherapy alone. The remaining patients proceeded to: endoscopic-assisted wide local excision (n = 2), anterior craniofacial resection (n = 4) or endoscopic craniofacial resection (n = 4). No patients had primary nodal disease or elective neck treatment. One patient had neoadjuvant chemoradiation. Six patients had post-operative radiotherapy; three received adjuvant chemotherapy. Two patients had late cervical node failure, and proceeded to neck dissection and post-operative radiotherapy. Two patients had late local recurrence. Ten-year overall and disease-free survival rates were 68.2 and 46.7 per cent, respectively.Conclusion:Longer-term follow up is supported given the incidence of late regional and local recurrence. Prophylactic treatment of cervical nodes in locally advanced disease is an area for further investigation.
