Start date: September 1, 2020
Phase:

The purpose of this study is to examine the benefits of a clinical implementation of a DPYD-genotype test to patients starting treatment with fluoropyrimidines (Fluorouracil (5-FU), capecitabine, tegafur).

NCT ID: NCT05129215 Completed - Rectal Cancer Clinical Trials

Development and Validation of The Post-RT LARS Prediction Model (PORTLARS)

PORTLARS
Start date: March 6, 2020
Phase:
Study type: Observational

Bowel dysfunction is common after a restorative rectal cancer resection. Neoadjuvant radiotherapy is an influential factor that impairs bowel function and quality of life. However, almost half patients who have received primary surgery with preoperative radiotherapy are able to restore a good or moderate bowel function in the long term. This multicenter observational study aims to identify the risk factors of severe bowel dysfunction after rectal cancer resection and neoadjuvant radiotherapy, in accordance with the LARS score, and to build a model that predicts long-term major LARS in the early stage of follow-up. Development and validation cohorts are enrolled from tertiary hospitals in China.

NCT ID: NCT05108753 Completed - Rectal Cancer Clinical Trials

Short-term Outcomes of Transanal Total Mesorectal Excision With Structured Training Curriculums in China

Start date: February 1, 2017
Phase:
Study type: Observational

Transanal total mesorectal excision (TaTME) is an alternative for mid-low rectal cancer. In China, this procedure has been performed in high-volume centers with structured training curriculums. This study aimed to evaluate the short-term outcomes during the initial implementation of the TaTME procedure in high-volume centers who followed structured training curriculums in China.

NCT ID: NCT05078515 Completed - Rectal Cancer Clinical Trials

Multicenter Validation of the PREDICT Score

Start date: January 1, 2008
Phase:
Study type: Observational

Even after adequate TME with grade III mesorectal grading, local recurrence remains a possible event. Several studies investigated different parameters and assessed their predictive power in regards to local recurrence after TME. These parameters included a variety of patient-related, tumor-related, and treatment-related factors. A recent meta-analysis reviewed the current literature for the predictors of local recurrence after TME for rectal cancer and developed a prognostic scoring system, the PREDICT score. The present study aimed to validate the PREDICT scoring system by applying it to a prospective cohort of patients with rectal cancer who underwent curative TME in three

NCT ID: NCT05074082 Completed - Rectal Cancer Clinical Trials

Perineal Flap Reconstruction Following Surgery for Advanced Pelvic Malignancy

Start date: July 31, 2021
Phase:
Study type: Observational

Flap reconstruction is utilised increasingly for repair of skin and soft tissue defects following pelvic exenteration. Many methods have been proposed but the outcomes associated with each remain largely unknown and the choice dependant on surgeon preference and patient/ disease characteristics. This review sought to assess the preferred methods for perineal reconstruction following pelvic exenteration by retrospectively assessing the outcomes associated with each at an international, multi-centre level.

NCT ID: NCT05040646 Completed - Rectal Cancer Clinical Trials

The Development of a Patient Reported Outcomes Measure Committed to the Watch-and-wait Program for Rectal Cancer

Start date: November 1, 2021
Phase:
Study type: Observational

The purpose of this study to develop an international tool that can be used to assess burden of disease in patients enrolled in the W&W program for rectal cancer

NCT ID: NCT04949672 Completed - Surgery Clinical Trials

Pathology Assessment of Mesorectal Fascia After TME by Laparoscopic, Open, TransAnal and Robotic Approaches (LOTARTME)

LOTARTME
Start date: January 2017
Phase:
Study type: Observational [Patient Registry]

TME is the gold standard surgical treatment of rectal cancer. Specimen quality, integrity of mesorectal fascia and lymph nodes harvest are expression of radicality and good surgery. The LOTARTME study is designed to assess which of the open, laparoscopic, robotic and endoscopic transanal approach is superior. Primary outcome is the evaluation of completeness of mesorectal fascia according to Quirke classification. Secondary outcomes are lymph nodes harvest, local recurrences, overall survivals, cancer related survivals. Inclusion criteria: any patient of any age and sex undergoing to intent-to-treat surgery operated by experienced surgeon. Exclusion criteria: patients with rectal cancer undergoing palliative surgery or multivisceral resection; all patients operated by less experienced surgeons. Study period January 1, 2017 - June 30 2021 and patients enrollment: January 1, 2017 - December 31, 2020. Data collection and analysis: data are collected in a prospective database and statical analysis is carried out using AnalystSoft StatPlus for Windows Software.

NCT ID: NCT04939103 Completed - Rectal Cancer Clinical Trials

TRUS-FNA For The Prediction Of pCR After Neoadjuvant Treatment In Rectal Cancer

Start date: July 1, 2021
Phase:
Study type: Observational [Patient Registry]

Colorectal cancer is one of the most malignancies worldwide. The dominant clinical research strategy of LARC includes neoadjuvant chemoradiotherapy before radical surgery followed combined with adjuvant treatment. Approximately 15% to 20% of the patients after nCRT can achieve a pathologic complete response (pCR)---no residual tumor is reported at histology after a standard resection. Some researchers suggest that those patients with pCR can be spared the morbidities of surgery instead by a nonoperative approach---watch- and-wait(W&W). However, neither FDG-PET, MRI, CT, nor enteroscopy can accurately determine a pCR. EUS-FNA has been an important technique for the diagnosis of rectal cancer for its high accuracy and little harm. However, data on the TRUS-FNA for the cytologic diagnosis of pCR in rectal cancer is scarce. Our hypothesis is that adding transrectal ultrasound-guided fine needle aspiration (TRUS-FNA) compared with enteroscopy , MR, and CT alone can improve the accuracy of predicting pCR after nCRT.Therefore, the aim of the study is to assess the performance characteristics of EUS-FNA in this setting.

NCT ID: NCT04920435 Completed - Rectal Cancer Clinical Trials

Prediction of the Response to Neoadjuvant Radiation Chemotherapy Through Texture Analysis Derived From Medical Imaging

RECTOMICS
Start date: January 2, 2019
Phase:
Study type: Observational

In patient with complete pathological response, surgery could be omitted without compromising progression-free or overall survival. A powerful prediction model is needed to guide management of this population. Radiomics features provide complementary information about tumor heterogenity. The aim of the investigators is to develop a model combining clinical and radiomic criteria able to predict complete pathological response.
