Randomized Controlled Trial Multicenter Study
Randomized, Double-Blind Phase II Trial With Prospective Classification by ATM Protein Level to Evaluate the Efficacy and Tolerability of Olaparib Plus Paclitaxel in Patients With Recurrent or Metastatic Gastric Cancer.
Gastric cancer cell lines, particularly those with low levels of ataxia telangiectasia mutated (ATM), a key activator of DNA damage response, are sensitive to the poly (ADP-ribose) polymerase inhibitor olaparib. We compared the efficacy of olaparib plus paclitaxel (olaparib/paclitaxel) with paclitaxel alone in patients with recurrent or metastatic gastric cancer and assessed whether low ATM expression is predictive of improved clinical outcome for olaparib/paclitaxel. ⋯ Olaparib/paclitaxel is active in the treatment of patients with metastatic gastric cancer, with a greater OS benefit in ATMlow patients. A phase III trial in this setting is under way.

Randomized Controlled Trial Multicenter Study Comparative Study
Epirubicin Plus Cyclophosphamide Followed by Docetaxel Versus Epirubicin Plus Docetaxel Followed by Capecitabine As Adjuvant Therapy for Node-Positive Early Breast Cancer: Results From the GEICAM/2003-10 Study.
Capecitabine is an active drug in metastatic breast cancer (BC). GEICAM/2003-10 is an adjuvant trial to investigate the integration of capecitabine into a regimen of epirubicin and docetaxel for node-positive early BC. ⋯ Invasive disease-free survival, but not OS, was significantly superior for patients with node-positive early BC who received the adjuvant standard schedule EC-T than for those who received the experimental ET-X regimen. Toxicity profiles differed substantially across arms.

Randomized Controlled Trial Multicenter Study Comparative Study
Capecitabine Plus Oxaliplatin Compared With Fluorouracil/Folinic Acid As Adjuvant Therapy for Stage III Colon Cancer: Final Results of the NO16968 Randomized Controlled Phase III Trial.
To report the final efficacy findings and biomarker analysis from the NO16968 trial comparing bolus fluorouracil/folinic acid (FU/FA) with capecitabine plus oxaliplatin (XELOX) in resected stage III colon cancer. ⋯ XELOX improved OS compared with bolus FU/FA in patients with resected stage III colon cancer after a median follow-up of almost 7 years. XELOX should be considered a standard adjuvant treatment option in patients with stage III disease. Tumoral dihydropyrimidine dehydrogenase expression is a promising predictive, and potentially, highly clinically relevant, biomarker for XELOX efficacy requiring further prospective evaluation.

Randomized Controlled Trial Multicenter Study
Fulvestrant 500 mg Versus Anastrozole 1 mg for the First-Line Treatment of Advanced Breast Cancer: Overall Survival Analysis From the Phase II FIRST Study.
To compare overall survival (OS) for fulvestrant 500 mg versus anastrozole as first-line endocrine therapy for advanced breast cancer. ⋯ There are several limitations of this OS analysis, including that it was not planned in the original protocol but instead was added after time-to-progression results were analyzed, and that not all patients participated in additional OS follow-up. However, the present results suggest fulvestrant 500 mg extends OS versus anastrozole. This finding now awaits prospective confirmation in the larger phase III FALCON (Fulvestrant and Anastrozole Compared in Hormonal Therapy Naïve Advanced Breast Cancer) trial (ClinicalTrials.gov identifier: NCT01602380).

Randomized Controlled Trial
Impact of Subsequent Therapies on Outcome of the FIRE-3/AIO KRK0306 Trial: First-Line Therapy With FOLFIRI Plus Cetuximab or Bevacizumab in Patients With KRAS Wild-Type Tumors in Metastatic Colorectal Cancer.
We investigated choice and efficacy of subsequent treatment, with special focus on second-line therapy, in the FIRE-3 trial (FOLFIRI plus cetuximab [arm A] or bevacizumab [arm B]) for patients with KRAS wild-type metastatic colorectal cancer. ⋯ Our data suggest that the sequence of drug application might be more important than exposure to single agents. In patients with RAS wild-type tumors, first-line application of anti-epidermal growth factor receptor-directed therapy may represent a favorable condition for promoting effective subsequent therapy including antiangiogenic agents.
