Randomized Controlled Trial Multicenter Study
Everolimus in metastatic renal cell carcinoma after failure of initial vascular endothelial growth factor receptor-tyrosine kinase inhibitor (VEGFr-TKI) therapy: results of an interim analysis of a non-interventional study.
Everolimus is approved for treatment of anti-vascular endothelial growth factor (VEGF)-refractory patients with metastatic renal cell carcinoma (mRCC). Clinical trials rarely mirror treatment reality. Thus, a broader evaluation of everolimus is valuable for routine use. ⋯ In routine clinical practice, everolimus is effective, as measured by median TTP (longer than median progression-free survival in RECORD-1 trial), and well tolerated. Our results support everolimus use in anti-VEGF-refractory patients with mRCC.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Adjuvant chemotherapy in stage III colon cancer with 5-fluorouracil and levamisole versus 5-fluorouracil and leucovorin.
Adjuvant chemotherapy for colon cancer has been established during the past decade. From 1990 until recently treatment with 5- fluorouracil (5-FU) and levamisole (LEV) lasting 12 months was recommended as standard treatment. At the initiation of this study in 1993 improvement of adjuvant therapy was expected by the modulation of 5-FU with folinic acid (FA). Therefore, we decided to perform a prospective randomized multicenter trial to compare standard 5-FU/LEV to 5-FU/FA for either 6 or 12 months. ⋯ Only a limited number of patients could be recruited in this study. The observed data support the results of other studies, which concluded that 6 months (or 12 months) treatment with 5-FU/FA is equivalent to 12 months treatment with 5-FU/LEV. Therefore the 6 months treatment with 5-FU/FA can be supported as standard for adjuvant therapy of stage III colon cancer.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Adjuvant radio-chemotherapy in stage II-III rectal cancer with 24-hour infusion of high-dose 5-fluorouracil and folinic acid: evaluation of feasibility.
Postoperative radio-chemotherapy has been established as standard treatment for stage II and III rectal cancer patients in the last decade. To improve the efficacy of this therapy, we decided to evaluate continuous 24-hour infusion of 5-fluorouracil (5-FU) with folinic acid (FA) in combination with local radiation versus standard bolus 5-FU/FA with local radiation in a randomized study. Here we report on the first 28 patients to receive the experimental treatment. ⋯ The high rate of premature treatment dropout indicate that the chosen schedule of weekly high-dose 5-FU/FA continuous infusion and combined postoperative radiotherapy should not be recommended for further use in postoperative adjuvant treatment.
