Colorectal cancer (CRC) is a leading cause of cancer morbidity and mortality. A well-defined precursor lesion (adenoma) and a long preclinical course make CRC a candidate for screening. This paper reviews the current evidence for the most important tests that are widely used or under development for population-based screening. ⋯ FS screening reduces CRC incidence and CRC mortality by removal of adenomas; FOBT reduces CRC mortality by early detection of cancer. Several other tests are available, but none has been evaluated in randomised trials. Screening strategies differ considerably across countries.

The FOLFOXIRI regimen developed by the Gruppo Oncologico Nord Ovest (GONO) demonstrated higher activity and efficacy compared with FOLFIRI in metastatic colorectal cancer (mCRC). Panitumumab is effective in some patients with KRAS codon 12-13 wild-type mCRC. KRAS codon 61, HRAS, NRAS, and BRAF V600E mutations might predict resistance to anti-epidermal growth factor receptor antibodies. ⋯ Adding panitumumab to FOLFOXIRI is feasible decreasing the dose of fluorouracil and irinotecan to reduce the risk of diarrhoea. Activity and secondary resectability of metastases among Ras-BRAF wild-type patients are promising.

Multicenter Study
Optimally tolerated dose of lapatinib in combination with docetaxel plus trastuzumab in first-line treatment of HER2-positive metastatic breast cancer.
This phase IB, open-label, dose-escalation study evaluated the safety, tolerability, and optimally tolerated regimen (OTR) of lapatinib in combination with docetaxel and trastuzumab in patients with previously untreated stage IV metastatic breast cancer (MBC) tumors overexpressing human epidermal growth factor receptor 2 (HER2). ⋯ NCT00251433.

To prospectively assess the efficacy of bilateral risk-reducing mastectomy (BRRM) when compared with surveillance on breast cancer (BC) risk and mortality in healthy BRCA1 and BRCA2 mutation carriers. ⋯ In healthy BRCA1/2 mutation carriers, BRRM when compared with surveillance reduces BC risk substantially, while longer follow-up is warranted to confirm survival benefits.
