Active clinical trials for "Neoplasm Recurrence, Local"

Colorectal cancer (CRC) is one of the most leading causes of cancer death in China. Although multiple treatment modalities including surgery, radiotherapy and chemotherapy have been developed, the prognosis of advanced CRC still remains poor. While around 30% of resectable advanced CRC could be cured. This study is designed to compare perioperative FOLFIRI versus adjuvant FOLFIRI in resectable advanced CRC who exposed to oxaliplatin in open-label, phase III mode.

This study is to evaluate the efficacy and toxicity of accelerated partial breast irradiation (ABPI) with intensity modulated radiation therapy (IMRT) in low-risk breast cancer treat with breast-conserving surgery.

All early breast cancer patients are offered adjuvant breast radiation therapy (RT) after breast conserving surgery for an early breast cancer. Breast cancer is heterogeneous, and selected patients have a very low gain from RT, whilst they still have risk of acute and late side effects from RT. This trial will try identify selection criteria for low risk breast cancer patients who can safely omit adjuvant RT without unacceptable high risk of local failure.

The purpose of this study is to determine the maximum dose that is safely tolerated of the experimental drug Rhenium Re 188 P2045. This will be done by first treating patients at relatively low doses of Rhenium Re 188 P2045, observing them closely to assure that there are no bad side effects, then increasing the dose when we are confident that it is safe to do so.

The primary objective of this trial is to investigate whether thermal ablation EMR with soft tip snare coagulation (STSC) reduces the recurrence rate of lateral spreading or sessile polyps ≥20mm compared to standard EMR.

The aim of the study is to evaluate whether tamoxifen at a low dose of 5mg/d reduces in the long term the incidence of invasive breast cancer and ductal carcinoma in situ, DCIS (DIN 1c, 2, 3) of the breast, in woman operated for lobular intraepithelial neoplasia (LIN1, 2 and 3) or ER-positive ductal intraepithelial neoplasia (DIN 1b, DIN2, DIN3, 1a excluded) of the breast. To improve the risk-benefit ratio, the use of lower doses of the drug has been proposed. Biomarker trials revealed that 5 mg/d was noninferior to 20 mg/d in inhibiting proliferation of breast cancer and normal endometrial tissue. By contrast, the risk of endometrial cancer si dose-dependent, and the dose reduction can lead a substantial decrease. Morover a dose of 5 mg/day is associated with an overall decrease of the estrogenic activity of tamoxifen on insulin like growth factor (IGF-I), sex hormone-binding globulin (SHBG) and antithrombin-III, with a decrease of venous thromboembolic events. Moreover, tamoxifen exhibits a high tissue distribution, so that a dose of 5 mg/day attains at the breast tissue level a concentration 10 times higher than that needed to inhibit cell growth in vitro. A prospective cohort study also showed that 10 mg on alternate days halves recurrence of DCIS in postmenopausal women. It has been shown that the treatment of dysplasia or pre-cancer drives the reduction of the invasive neoplasms onset. This is a chemoprevention trial designed to validatate the low-dose Tamoxifen in women with diseases at high evolutionary risk. The demonstration of efficacy and safety of such a treatment for the prevention of the invasive breast cancer would lead improvements in term of survival and quality of life for the patients at increased risk.

This is a phase 3 randomized, active-controlled, open-label, multicenter study that will be conducted in approximately 120 investigational sites worldwide. Subjects with either recurrent or refractory NMIBC (Ta high grade, T1 low or high grade, CIS) will be eligible for participation in this study. Refractory disease is defined as evidence of persistent high grade bladder cancer (Ta HG, T1, and/or CIS) at least 6 months from the start of a full induction course of BCG with or without maintenance/re-treatment at 3 months. Recurrent disease is defined as reappearance of disease after achieving a tumor-free status by 6 months following a full induction course of BCG with or without maintenance/re-treatment at 3 months. Subjects with recurrent disease must have recurred within 18 months following the last dose of BCG. Approximately 450 subjects will be randomized. The primary objective of this study is to evaluate the efficacy of intravesical EN3348 as compared with mitomycin C in the treatment of subjects with recurrent or refractory NMIBC. The secondary objective is to evaluate the safety of EN3348 as compared with mitomycin C in the treatment of subjects with BCG recurrent or refractory NMIBC. This study will consist of 4 phases: Screening, Induction, Maintenance and Follow-Up and will be conducted over 3 years.

Besides liver transplantation, the curative treatment of primary hepatic cancer with cirrhosis remains the surgical resection. Radiofrequency or cryotherapy currently allow local ablation of small cancer, with very good results. However, all these treatments are followed by high rates of recurrence (50 - 70% at 5 years). Then, it seems essential to associate to the surgical resection or to the local ablation as "adjuvant" treatment, in order to prevent or to decrease the rate of recurrence. However, no evidence supports this attitude. Therefore, following curative treatment of primary hepatic cancer with cirrhosis, we propose to compare treated to untreated patients. Postoperative treatment means either intra-arterial chemotherapy or systemic chemotherapy. The main criterion of the study is time of survival without recurrence. The main secondary objective is the safety.

This study is to investigate the safety of NS-9 and to see how well it is tolerated in patients with cancer that has metastasized (spread) to the liver from another primary tumor. NS-9 is a drug developed to go to the liver to cause cell death specifically in tumor cells. This study is also set up to determine the best dose to use.

This prospective, multicentric single arm phase II study is based on the protocol of the international TARGIT-A study. The purpose is to investigate the efficacy of a single intraoperative radiotherapy treatment within elderly low risk patients (≥ 70 years, cT1, cN0, cM0, invasive-ductal) which is followed by WBRT only when risk factors are present. In presence of risk factors postoperative WBRT will be added to complete the radiotherapeutic treatment according to international guidelines.
