NCT ID: NCT03646955 Recruiting - Pain Clinical Trials

Partial Breast Versus no Irradiation for Women With Early Breast Cancer

Start date: September 5, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02087475 Recruiting - Surgery Clinical Trials

Perioperative FOLFIRI VS Adjuvant FOLFIRI in Resectable Advanced CRC Failed to Oxaliplatin

Start date: January 2011
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT01895673 Completed - Liver Neoplasms Clinical Trials

PET-MRI After Radiofrequency Ablation (RFA) or Microwave Ablation (MWA)

Start date: June 2013
Phase: N/A
Study type: Observational

The primary objective of this study is to evaluate the ability of PET-MRI and to detect a local site recurrence during the first year of follow-up after RFA or MWA of colorectal liver metastases (CRLM) as compared with contrast enhanced (ce) CT and PET-CT. Standard reference will be clear focal uptake in the rim of the lesion on PET-CT, possibly in combination with histology (when available) or clinical follow-up. Secondary outcomes are the inter-observer variability, the ability to diagnose new intrahepatic lesions and in what way PET-MRI is able to influence future treatment compared to PET-CT and ceCT. The patients satisfaction concerning the PET-MRI will be examined with a questionnaire.

NCT ID: NCT01343459 Completed - Toxicity Clinical Trials

Intra-Operative Electron Boost and Hypofractionated Whole-Breast Irradiation During Breast-conserving Treatment (BCT)

HIOB
Start date: January 2011
Phase: N/A
Study type: Interventional

Title: HIOB - Hypofractionated Whole-Breast Irradiation preceded by Intraoperative Radiotherapy with Electrons as anticipated Boost ISIORT- 01 HIOB is defined as hypofractionated WBRT (40,5 Gy in 2,7 Gy per fraction) preceded by an Intraoperative Boost to the tumor bed ( 90 % reference dose of 10 Gy, 11,1 Gy Dmax IOERT). Primary endpoint is the proof of superiority of a new treatment regimen. The HIOB study concept is supposed to test the hypothesis whether such a combined schedule is superior (or iso-effective) towards "standard" RT in terms of local control and cosmetic outcome. In the vast majority of all publications, annual and 5 year in-breast recurrence rates following BCT showed a clear dependency on patient age within the following boundaries (primary references): Age > 50: Bartelink (standard): 0,7% (annual) 3,5% (5y) START B (best): 0,4 %(annual) 2,0% (5y) Age 41-50: Bartelink (standard) 1,2% (annual) 6,0% (5y) Whelan (best) 0,72%(annual) 3,6% (5y) Age ≥ 35-40 Bartelink (standard) 2% (annual) 10% (5y) Whelan (best) 0,72% (annual) 3,6% (5y) long these three different age groups, benchmarking will be performed against the best published results following 'Golden Standard'RT, usually defined as conventionally fractionated WBRT with 50 Gy (25 x2) plus external tumor bed boost with 10-16 Gy electrons (5-8x2Gy). Superiority is defined as going below the lower limit of the estimated 5 year local recurrence rate within the respective age group Inferiority is defined as crossing the respective upper limit . Secondary endpoint: Disease free survival Tertiary endpoint: toxicity assessment (acute and late) including long term cosmetic evaluation Study design and statistics: - Prospective multicenter single-armed - Sequential probability ratio test (SPRT) - Separate analysis within three different age groups Estimated Accrual time: strongly dependent on recruitment per year within the respective age group . Due to the statistical estimation of Szenario A and B the study will close after max. Time-period of 10 years in case of A or 6,4 years in case of B..
