VAZQUEZ, Valeria et al. Molecular detection of minimal residual disease in melanoma and solid tumors. Medicina (B. Aires) [online]. 2009, vol.69, n.1, pp. 181-190. ISSN 1669-9106.

The availability of highly sensitive and specific methods for the detection of minimal residual disease in patients with solid tumors may have important prognostic and therapeutic implications. One of the most widely used methods for the molecular detection of cancer cells is the RT-PCR technique, which leads to the amplification of tissue-specific mRNA. It was firstly applied in the detection of circulating tumor cells in peripheral blood of patients with advanced melanoma; and soon it was adapted for the detection of minimal residual disease in other solid tumors. The aim of the present review is to evaluate the published data since the first study in 1991 and to analyze the clinical value of the findings obtained. The importance of sample handling and standardization of RT-PCR procedures is also discussed.
