Recurrence Of Rectal Cancer

Abstract Purpose To compare the diagnostic performance of 18F-fluorodeoxyglucose-PET/MRI and MRI in the diagnosis of pelvic recurrence of rectal cancer. Methods All PET/MRIs of patients in the follow-up of rectal cancer performed between 2011 and 2018 at our institution were retrospectively reviewed. Recurrence was confirmed/excluded either by histopathology or imaging follow-up (> 4 months). Four groups of readers (groups 1/2: one radiologist each, groups 3/4: one radiologist/one nuclear medicine physician) independently interpreted MRI and PET/MRI. The likelihood of recurrence was scored on a 5-point-scale. Inter-reader agreement, sensitivity, specificity, PPV/NPV and accuracy were assessed. ROC curve analyses were performed. Results Fourty-one PET/MRIs of 40 patients (mean 61 years ± 10.9; 11 women, 29 men) were included. Sensitivity of PET/MRI in detecting recurrence was 94%, specificity 88%, PPV/NPV 97% and 78%, accuracy 93%. Sensitivity of MRI was 88%, specificity 75%, PPV/NPV 94% and 60%, accuracy 85%. ROC curve analyses showed an AUC of 0.97 for PET/MRI and 0.92 for MRI, but the difference was not statistically significant (p = 0.116). On MRI more cases were scored as equivocal (12% versus 5%). Inter-reader agreement was substantial for PET/MRI and MRI (0.723 and 0.656, respectively). Conclusion 18F-FDG-PET/MRI and MRI are accurate in the diagnosis of locally recurrent rectal cancer. Sensitivity, specificity, PPV, NPV and accuracy are comparable for both modalities, but PET/MRI increases readers’ confidence levels and reduces the number of equivocal cases. Graphic abstract

The Difference

433 Background: Neoadjuvant fluoropyrimidine-based chemotherapy (ChT) plus radiotherapy (Rt) is a standard approach for locally advanced rectal cancer. Polymorphisms of thymidylate synthase (TS), the target for fluoropyrimidines, are recognized prognostic factors in colon cancer. The aim of this study was to evaluate the prognostic value of the polymorphisms of TS in rectal cancer after neoadjuvant ChT plus Rt. Methods: We studied one-hundred consecutive patients with stage II/III rectal cancer between November 2001 and March 2009. Patients underwent surgery 6-8 weeks after neoadjuvant Rt (5,040 cGy) plus fluoropyrimidine-based ChT. DNA was extracted from paraffin embedded biopsies. TS1494del6 and 5′-28bp repeat +G/C SNP polymorphisms were determined. Results: Sixty-seven percent were men and median age was 67 years. ypT stage was: T0 9%, T1 2%, T2 27%, T3 60% and T4 2%; 32% had locoregional adenopathies. The median follow-up was 45 months and relapse occurred in 20% of patients. Polimorphisms could be determined in 98% of pt: -6bp/-6bp 10%, - 6bp/+6bp 39%, +6bp/+6bp 51% and 2R/2R 72%, 2R/3R 21%, 3R/3R 6%. The grade of pathological tumour regression was not associated with polymorphisms. Relapses occurred in 40% of patients -6bp/-6bp, 22% of patients -6bp/+6bp and 21% of patients +6bp/+6bp. The difference in disease- free survival (DFS) between the first and the third groups was stadistically significative (p=0.049). No relation between 5′-28bp repeat +G/C SNP polymorphism and DFS was found. Conclusions: Our data suggest that the TS1494del6 polimorphism may be an important prognosis factor in rectal cancer receiving neoadjuvant chemoradiotherapy. No significant financial relationships to disclose.

Objective This study was performed to evaluate the diagnostic value of the neutrophil CD64 index in patients with sepsis in the intensive care unit (ICU). Methods Patients with sepsis who were treated at the ICU of the authors’ institution from December 2016 to June 2018 were retrospectively reviewed. The controls comprised age- and sex-matched patients who underwent coronary bypass and had no evidence of infection. The neutrophil CD64 index, C-reactive protein (CRP) level, and procalcitonin level were compared between the two groups. The diagnostic performance of these measures, including the sensitivity, specificity, and area under the receiver operating characteristic (ROC) curve, was examined. Results In total, 35 patients with sepsis and 27 control patients were included in the data analysis. The sensitivity of the neutrophil CD64 index, CRP level, and procalcitonin level was 83%, 74%, and 77%, respectively. The specificity was 88%, 86%, and 81%, respectively. The area under the ROC curve was 0.923 [95% confidence interval (CI), 0.856–0.989], 0.904 (95% CI, 0.832–0.976), and 0.863 (95% CI, 0.776–0.950), respectively. Conclusion The neutrophil CD64 index is a valuable biomarker for diagnosing sepsis in patients in the ICU.

The Difference

Abstract Background: Neoadjuvant chemoradiotherapy (CRT) can downstage rectal carcinoma, resulting in superior resectability, better local control and survival benefits. However, it is unclear whether patients treated with CRT and those who did not have similar outcomes at the same pathological stage. This study aimed to investigate the long-term outcomes of ypT1-3N0 mid-low rectal cancer who received neoadjuvant CRT followed by total mesorectal excision (TME) compared with pT1-3N0 rectal cancer immediately managed with surgery. Methods: We retrospectively enrolled 180 patients with pT1-3N0 or ypT1-3N0 rectal cancer located within 10cm from the anal edge who underwent TME between 2009 and 2015. Of these patients, 63 received neoadjuvant CRT, while 117 underwent radical proctectomy without preoperative therapy. The disease-free survival (DFS) and cancer-specific survival (CSS) were compared between the two groups. Results: Within a median follow-up time of 65 months, the 5-year DFS was lower in the CRT group than the non-CRT group (74.9% vs. 92.6%, P=0.001), and the 5-year CSS presented a similar trend as well (89.6 % vs. 97.1%, P=0.054). By subgroup analysis, the difference in DFS and CSS was mainly caused by the difference between ypT3N0 and pT3N0 disease (71.1% vs. 96.1%, P＜0.001 and 90.9% vs. 100%, P=0.029, respectively). However, patients with ypT1-2N0 had an analogous prognosis to those with pT1-2N0 disease (77.9% vs. 89.0%, P=0.225 and 88.1% vs. 94.2%, P=0.292, respectively). Multivariate analysis indicated that neoadjuvant CRT was not an independent predictor of DFS. Conclusion: After neoadjuvant CRT followed by TME, patients with ypT1-2N0 rectal cancer had an analogous prognosis to those with initial pT1-2N0 disease, whereas patients with ypT3N0 rectal cancer had worse prognosis compared with that of pT3N0 disease.

Abstract Aim To analyze the effect of preserving the left colic artery (LCA) on long-term oncologic outcomes during laparoscopic low anterior resection of rectal cancer. Methods Clinicopathological and follow-up patients undergoing laparoscopic low anterior resection of rectal cancer in general surgery department of Guangdong Provincial People's Hospital from January 2014 to December 2015 were retrospectively collected. According to the difference surgical methods of inferior mesenteric artery (IMA), 159 cases were divided into the LCA preservation group and 225 cases in the LCA non-preservation group. The 5-year rates of overall survival (OS) and disease-free survival (DFS) were compared between two group. Results 384 patients were included in final analysis. Anastomotic leakage occurred in 7 patients (4.4%) in the LCA preservation group and in 16 patients (7.1%) in the LCA non-preservation group. The follow-up rate was 91.2% (145/159) during 5–60 months in LCA preservation group, and 89.8% (202/225) during 5–60 months in the LCA non-preservation group. The number of patients who developed death, local recurrence and metastasis were 59 (37.1%), 13 (8.2%) and 60 (37.7%) in the LCA preservation group, and 86 (38.2%), 20 (8.9%) and 92 (40.9%) in the LCA non-preservation group, without significant differences (all P ༞ 0.05). The 5-year OS and DFS rates were 69.0% and 59.3% in the LCA preservation group, and 68.8% and 55.9% in the LCA non-preservation group, without significant differences (all P ༞ 0.05). After stratification by TNM Stage, the difference on 5-year OS rates and DFS rates of I stage, II stage and III stage in two groups were no significant as well (all P ༞ 0.05). Conclusions The long-term oncologic outcomes of laparoscopic low anterior resection of rectal cancer with preservation of the LCA are comparable with ligation at origin of IMA.
