Randomized Controlled Trial Multicenter Study Clinical Trial
Locally advanced/inflammatory breast cancers treated with intensive epirubicin-based neoadjuvant chemotherapy: are there molecular markers in the primary tumour that predict for 5-year clinical outcome?
Locally advanced and/or inflammatory breast cancer (LABC) is a heterogeneous disease. Molecular markers may help to understand this heterogeneity. This paper reports the results of a study assessing the potential prognostic or predictive value of HER-2, p53, cyclinD1, MIB1, ER and PgR expression by immunohistochemistry from patients included in an EORTC-NCIC-SAKK trial. ⋯ p53 was an independent factor predicting for survival. In order to clarify whether p53 is a pure prognostic and/or a predictive factor, a phase III trial is being conducted (EORTC 10994/BIG 00-01 study) using functional assay in yeast from frozen tumour samples.

Randomized Controlled Trial Clinical Trial
5-Fluorouracil plus leucovorin is an effective adjuvant chemotherapy in curatively resected stage III colon cancer: long-term follow-up results of the adjCCA-01 trial.
Adjuvant postoperative treatment with 5-fluorouracil (5-FU) and leucovorin in curatively resected stage III colon cancer significantly reduces the risk of cancer recurrences and improves survival. The impact of 5-FU plus leucovorin on survival and tumor recurrence was analyzed in a long-term follow-up study in comparison with the effects of 5-FU plus levamisole in the prospective multicenter trial adjCCA-01. ⋯ After curative resection of a stage III colon cancer, adjuvant treatment with 5-FU plus leucovorin is generally well tolerated. This long-term follow-up study demonstrates that adjuvant treatment with 5-FU plus leucovorin given for 12 cycles is significantly more effective than 5-FU plus levamisole (Moertel scheme) in reducing tumor relapse and improving survival.
