Filter by:This phase II trial studies how a diet intervention works in improving bowel dysfunction symptoms related in colon or rectal cancer survivors. Changing a diet may be helpful in reducing the severity of bowel symptoms, including diarrhea and constipation, and improve quality of life in colon or rectal cancer survivors and help doctors learn how to help patients better in the future.
The purpose of the study is to compare pre-operative radio-chemotherapy (RT + capecitabine) to a short course RT associated with a delayed surgery, with two primary objectives: the efficacy evaluation (rate of R0 resection) and the preservation of autonomy (score IADL).
Phase II study of up-front chemotherapy and neo-adjuvant shortcourse radiotherapy for resectable rectal carcinoma. Study Design: Phase II, open-label, single-arm, multi-centre study. STUDY PRODUCT,DOSE,ROUTE,REGIMEN AND DURATION OF ADMINISTRATION: 1. Neoadjuvant Treatment (pre-operative chemo-radiotherapy regimen): FOLFOX4* 2 cycles (WK1+WK3) - Tomotherapy** (WK5) - FOLFOX4* 2 cycles (WK7+WK9) * Oxaliplatin 85 mg/m2 iv: day 1 Levofolinate 100 mg/m2 iv: day 1-2 5-fluorouracil 400 mg/m2 iv in bolus and 600 mg/m2 iv infusion over 22h: day 1-2 Every cycle will last 2 weeks (approximately 48 hours of treatment infusion and 12 days of rest). ** 25 Gy in 5 consecutive fractions, one fraction per day in 5 days on CTV (Clinical Target Volume) at the isodose of the 95% of the total dose. The treatment plan will be elaborated at the work-station dedicated to the Helicoidal Tomotherapy. The treatment could be planned also with linear accelerator with IGRT-IMRT technique or VMAT technique. 2. Restaging (week 11) 3. Surgery (week 12-16) with Total Mesorectal Excision (TME) 4. End Of Treatment (week 16-32) 5. Adjuvant therapy (The maximum interval between surgery and start of adjuvant therapy should be 8 weeks): 6. FOLFOX4* 8 cycles (every 2 weeks) Study Duration: about 5 years. Enrollment period: 36 months. Treatment period: about 8 months. Follow-up: 1 year. NUMBER OF SUBJECTs: · Step A: a maximum of 6 patients. 6 evaluable patients are needed to assess toxicity. If 1 toxicity resulting in discontinuation of treatment will be observed in 6 patients, the treatment can be considered safe (with a confidence > 90%). If 2 or more toxicity resulting in discontinuation of treatment on 6 patients, the study will be stopped because not safe and another type of radiotherapy schedule must be designed. · Step B: a total of 50 patients is required to be recruited in 2 years (including patients enrolled in Step A). The goal is to achieve a proportion of at least 15% of patients with a complete pathological response with the new radiochemotherapeutic treatment.
This is a single arm, single center pilot study of 40 patients with uT3N0 or uT1-3N+ rectal cancer receiving pre-operative chemoradiation. Subjects will undergo PET/MRI scans before and after surgery.
Total mesorectal excision (TME) is a precise dissection of the rectum and all para-rectal lymph nodes within the mesorectal envelope. It is becoming universally recognized and accepted as the standard technique for surgical excision of rectum carcinomas. TME results in lowest rates of local recurrence, especially when combined with pre-operative chemo-radiotherapy. Especially after pre-operative chemo-radiotherapy, the post-operative drainage may be important. The quick decrease of this drainage will enable the early mobilisation of the patient and may shorten the time of hospitalization. If this decrease in fluid production can be achieved, it will have a positive effect on the Quality of Life of the patient and will ensure health economic savings by reduction of hospitalization time and resources. Somatostatin analogues have shown to be able to decrease the secretion of numerous types of bodily fluids. The aim of this study is to investigate if lanreotide Autogel 120mg is capable to reduce the fluid discharge in patients that underwent a TME for rectumcarcinoma. Lanreotide Autogel 120mg compared to placebo, administered post-surgery on the fluid discharge in the drain of the patient that underwent a total mesorectum excision (TME) for rectal carcinoma. Patient planned to have a TME will be asked to participate in the study. When they have provided written informed consent, they will be randomized 1:1 to receive either placebo or lanreotide autogel 120mg. Drain fluid will be checked for hematocrit daily post-surgery. Once hematocrit levels of the drain fluid are <10%, study medication or placebo will be administered. After administration the volume of the drain fluid will be measured every 12 hours for at least 5 days. A sample of the drain fluid will be collected every 24 hours for at least 5 days and frozen at -70°C for total protein content, sodium and chloride analysis afterwards. If the patient has a hematocrit >10% in his drain fluid for a period of 5 days, this patient can not be randomized.
The purpose of this study is to determine whether the tailored management of locally advanced rectal carcinoma can improve the oncologic and functional outcome.
Determine if genotype-directed neoadjuvant chemoradiation, using information from the thymidylate synthase promoter polymorphism, result in a greater degree of tumor downstaging in high risk patients compared to historical controls.
