Filter by:The purpose of this study is to establish the influence of time-interval between preoperative hyperfractionated radiotherapy (5x5 Gy) and surgery on long term overall survival (5 years), local and distant recurrence rate, downstaging rate, sphincter saving procedures, radical resection rate (R0) in patients with locally advanced rectal cancer operated on according to TME technique. In particular 3D endosonography and 3rd generation ultrasonic contrast agents are evaluated to assess response to radiotherapy.
This study aims to investigate the combination of panitumumab and a 5-FU-based RCTX in patients with locally advanced KRAS wild-type rectal cancer.
Phase II pilot study of a preoperative induction chemotherapy in combination with Bevacizumab followed by combined radiochemotherapy for patients with locally advanced rectal carcinoma
Sexual dysfunctions are well-recognized complications after rectal cancer surgery. Damage to the pelvic plexus and pelvic splanchnic nerves results in ejaculatory dysfunction. The purpose of this study is to evaluate the efficacy of Udenafil(Zydena®, Dong-A Pharmaceutical co., Ltd, Seoul, Korea) in penile rehabilitation for patients who undertake total mesorectal excision.
The purpose of this study is to determine whether topical nitroglycerin in addition to 5-flourouracil and radiation therapy are effective in the treatment of operable rectal cancer.
The purpose of this study is to determine whether an optimal dose of [6R] 5,10-methylenetetrahydrofolate (arfolitixorin) in combination with pemetrexed are effective in pre-operative treatment of patients with resectable rectal cancer.
In this phase I trial neoadjuvant CCRT combining IMRT with three escalated dose levels (45 Gy, 50 Gy, and 55 Gy in 25 fractions) and BV-fluorouracil/ leucovorin/oxaliplatin (FOLFOX) regimens is planned for 15 locally advanced rectal cancer patients. The primary goal is to define the maximally tolerated dose of radiotherapy and the treatment related acute toxicity, and to demonstrate that preoperative highly conformal IMRT and concurrent BV-chemotherapy will lead to acceptable acute gastrointestinal morbidity. The secondary goal is to demonstrate that this treatment modality will elicit a comparable or improved rate of T stage downstaging and complete response pathologically.
The aim of this study is to recruit 50 rectal cancer patients planned to receive standard radiochemotherapy. A baseline ultrasonic elastography is performed prior to radiochemotherapy and followed by re-scans two and six weeks after initiation of treatment. The objective quantitative elastography findings are compared with the TRG score. The purpose is to elucidate ultrasonic elastography's ability to predict treatment response at an early stage by comparing quantitative ultrasound parameters before, during and after treatment with MR scan results and histopathological Tumor Regression Grade (TRG score) after operation.
The main purpose of this study is to find the maximum tolerable dose of sorafenib when administered along with another drug called 5-Fluorouracil (5-FU) and to find out more about whether these drugs, along with radiation, can help people with rectal cancer when given before surgery. 5-FU and radiation are both approved by the US Food and Drug Administration (FDA) for use in people with rectal cancer. The investigators will utilize a standard 3 + 3 phase I study design. In the phase I part of the study, the investigators will attempt dose escalation of sorafenib in combination with standard infusional 5-FU and external beam at standard doses. Clinical staging should be done by endorectal ultrasound (ERUS) and/or pelvic magnetic resonance imaging (MRI) for T and N stage; chest and abdomen computed tomography (CT) for staging of metastatic disease; undergo sigmoidoscopy and/or colonoscopy done by crude odds ratios (CORS); biopsy is taken for diagnosis and extra is sent for tissue bank. At the maximum tolerated dose (MTD) of sorafenib we will expand the cohort to 6 more patients to further evaluate toxicity profile and efficacy.
The parameter that best correlates with 5 years disease-free survival (DFS ) in patients (pts) with localized rectal cancer (RC) is the pathological TNM staging (ypTNM) after chemo-radiotherapy (Ch-RT). DFS is 97% in pts with ypT0N0M0 = ypCR and 42% in pts with ypN +. Standard 5-FU Ch-RT achieves 15% of ypCR. The use of IMRT achieves a high proportion of ypCR . This study aimed to demonstrate in a prospective manner the feasibility of personalizing Ch regimen base in TT in combination with IMRT in patients with RC. Secondary objectives included the number of ypCR and safety.
