T1 Rectal Cancer

The Ferguson Operating Anoscope (FOA) is a surgical instrument, which can facilitate transanal excision of appropriate rectal tumors within 15 cm of the anal verge. Previous work showed low recurrence (4.3%) for favorable T1 tumors (no lymphovascular invasion, well/moderate differentiation, negative margins). This follow-up study evaluates outcomes in rectal cancer excised with FOA at a tertiary care center. T1 rectal cancer patients were identified in a prospectively maintained database. Tumor pathology and patient characteristics were reviewed. Primary outcomes include tumor recurrence and patient and disease-free survival. Secondary outcomes are quality of excision (intact specimen). Twenty-eight patients had pathologic stage T1 rectal cancer (average 8 ± 2.6 cm from the anal verge). Final path demonstrated 14 per cent to be well differentiated, 82 per cent moderately differentiated, and 93 per cent without angiolymphatic invasion. All specimens removed were intact. One patient had a true local recurrence and underwent a salvage operation 24 months after her index operation. Patient survival was 96.4 per cent (n = one death from primary lung cancer) at median follow-up 64 ± 35 months. With appropriate tumor selection and quality of initial resection, FOA has demonstrated utility in achieving optimal oncologic resection of T1 rectal tumors.

Abstract Purpose Glove single-port laparoscopy-assisted transanal total mesorectal excision (TaTME) has been successfully carried out in our medical center. The purpose of this study is to evaluate the feasibility of this emerging operation. Methods This technique was performed by self-made glove single-port laparoscopic platform to radically resect low rectal cancer. Short-term postoperative results, including complications, length of hospital stay, and follow-up results were collected and analyzed statistically. Results There are five consecutive patients (three males, two females) who underwent this surgery and included in this study. The mean distance from the tumor to the anal verge was 4.8 cm (range 4.0–6.0). The surgery was completed in all cases, and the rectal tumor was removed successfully without conversion; circumferential margins of all the excised specimens were negative. The mean time of operation was 338.00 min (range 280–400). The average number of lymph node dissection was 12.20. The average postoperative hospital stay was 8.60 days. During the follow-up (14.80 ± 1.92 months), all preventive ileostomies were successfully closed in about 3 months after the surgery, all patients had satisfactory anal function, and no tumor recurrence was found. Conclusion Glove single-port laparoscopy-assisted TaTME has a significant effect in specific patients with low rectal cancer, with rapid recovery and high safety. Prospective randomized studies involving more case counts and long-term follow-up results, especially oncologic outcomes, are needed to validate this technique.

PurposeDistant metastases are currently the main cause of treatment failure in locally advanced rectal cancer (LARC) patients. The aim of this research is to investigate a correlation between the variation of radiomics features using pre- and post-neoadjuvant chemoradiation (nCRT) magnetic resonance imaging (MRI) with 2 years distant metastasis (2yDM) rate in LARC patients.Methods and MaterialsDiagnostic pre- and post- nCRT MRI of LARC patients, treated in a single institution from May 2008 to June 2015 with an adequate follow-up time, were retrospectively collected. Gross tumor volumes (GTV) were contoured by an abdominal radiologist and blindly reviewed by a radiation oncologist expert in rectal cancer. The dataset was firstly randomly split into 90% training data, for features selection, and 10% testing data, for the validation. The final set of features after the selection was used to train 15 different classifiers using accuracy as target metric. The models’ performance was then assessed on the testing data and the best performing classifier was then selected, maximising the confusion matrix balanced accuracy (BA).ResultsData regarding 213 LARC patients (36% female, 64% male) were collected. Overall 2yDM was 17%. A total of 2,606 features extracted from the pre- and post- nCRT GTV were tested and 4 features were selected after features selection process. Among the 15 tested classifiers, logistic regression proved to be the best performing one with a testing set BA, sensitivity and specificity of 78.5%, 71.4% and 85.7%, respectively.ConclusionsThis study supports a possible role of delta radiomics in predicting following occurrence of distant metastasis. Further studies including a consistent external validation are needed to confirm these results and allows to translate radiomics model in clinical practice. Future integration with clinical and molecular data will be mandatory to fully personalized treatment and follow-up approaches.
