Sensitivity of Various Evaluating Modalities for Predicting a Pathologic Complete Response After Preoperative Chemoradiation Therapy for Locally Advanced Rectal Cancer.

CONCLUSION: The various evaluation methods for predicting a pCR after PCRT show a predictive sensitivity of 0.15-0.41 for primary tumors and 0.52-0.88 for lymph nodes. Endoscopy is a relatively superior modality for predicting the pCR of the primary tumor of LARC patients. PMID: 31726004 [PubMed]

BACKGROUND: In 2016, the American Society of Colon and Rectal Surgeons published a rectal cancer surgery checklist composed of the essential elements of preoperative, intraoperative, and postoperative care for patients undergoing rectal cancer surgery. OBJECTIVE: The purpose of this study was to assess whether compliance with preoperative checklist elements was associated with improved pathologic and 30-day postoperative outcomes after rectal cancer surgery. DESIGN: This was a retrospective cohort study. SETTINGS: The study involved North American hospitals contributing to the American College of Surgeons Nation...

CONCLUSIONS: Resections that were approached laparoscopically were more likely to achieve oncologic success. Minimally invasive approaches did not lengthen operative times and provided benefits of reduced surgical site complications and decreased postoperative length of stay. Further studies are needed to clarify clinical outcomes and factors that influence the choice of approach. See Video Abstract at http://links.lww.com/DCR/B70.

CONCLUSIONS: The rates of total mesorectal excision performance and grade assignment are widely variable throughout the state of Michigan. Overall, grade assignment remains very low. This suggests an opportunity for quality improvement projects to increase total mesorectal excision performance and grading, involving both the surgeons and pathologists for effective implementation.

CONCLUSIONS: Local drainage procedures maintained primary anastomosis in 50% of cases after an anastomotic leakage. See Video Abstract at http://links.lww.com/DCR/B57. ¿PUEDE UN DRENAJE LOCAL SALVAR UNA ANASTOMOSIS COLORRECTAL O COLOANAL FALLIDA? UNA COHORTE PROSPECTIVO DE 54 PACIENTES ANTECEDENTES: Los drenajes locales se pueden utilizar para controlar las fugas en pacientes seleccionados sin peritonitis. OBJETIVO: El objetivo de este estudio fue evaluar la eficacia de los procedimientos de drenaje, para mantener una anastomosis primaria baja, después de una fuga anastomótica. DISEÑO: ...

Authors: Takeuchi N, Koike K, Yoshida S, Fujiwara M Abstract Recent therapeutic advancements have prolonged the survival duration of patients with metastatic or recurrent colorectal cancer even during salvage treatment. Although treatment with regorafenib and trifluridine/tipiracil combination has exhibited apparent survival benefits, clear and objective evidence of a response to these drugs is scarce. Herein, the present study reports the case of a patient with rectal cancer refractory to multiple surgical interventions and standard chemotherapy. Treatment with regorafenib resulted in immediate improvement of resp...

COLLABORATIVE CLUSTERING OF SUBJECTS AND RADIOMIC FEATURES FOR PREDICTING CLINICAL OUTCOMES OF RECTAL CANCER PATIENTS. Proc IEEE Int Symp Biomed Imaging. 2019 Apr;2019:1303-1306 Authors: Liu H, Li H, Boimel P, Janopaul-Naylor J, Zhong H, Xiao Y, Ben-Josef E, Fan Y Abstract Most machine learning approaches in radiomics studies ignore the underlying difference of radiomic features computed from heterogeneous groups of patients, and intrinsic correlations of the features are not fully exploited yet. In order to better predict clinical outcomes of cancer patients, we adopt an unsupervised machine learning ...

We present the case of a patient with tubulovillous adenocarcinoma of the anal canal which relapsed after chemoradiation. The patient refused salvage surgery and was treated with definitive electrochemotherapy under general anesthesia. Tumor electroporation performed with the insertion of three needles in the recurred site was preceded by an intravenous bolus of bleomycin. After the administered treatment, the patient showed a complete clinical response. A year after electrochemotherapy, the patient is free from local disease with excellent preservation of the sphincter function. Electrochemotherapy may be considered as an...

This study reviewed the applicability of laparoscopy in this challenging setting.MethodsRetrospective analysis of patients who underwent trans-abdominal re-operative rectal surgery from 2010-2019 was performed.ResultsSeventy-eight patients [35 females (45%); BMI 25kg/m2) were included. Reasons for reoperation were recurrent cancer in 18 (43%) patients and anastomotic failure in 57 (73%). Twenty-two (28%) had laparoscopic surgery and 4 had attempted laparoscopy converted to laparotomy. A higher success rate was noted for laparoscopy with prior laparoscopic surgery. Benefits of laparoscopy included significant reduction in l...
