Abstract Background and objective Five years’ data relative survival (RS) is presented in 3 solid tumours: breast, colorectal (CRC) and lung and 2 haematologic neoplasms: large B cell lymphoma (NHL-B) and multiple myeloma (MM) treated at Institut Catala d’Oncologia between 2010 and 2011 in comparison with the results obtained in a historical special cohort from 1998 to 1999. Material and methods A database was created in a common safe and accessible repository. We have introduced more than 5,000 medical records. To analyze the results the statistical package R ® was used for RS. Results The overall RS at 5 years for 2010–2011 was: CRC 67%, breast 93.6%, lung 28%, NHL-B 68% and MM 62%, while for 1998–1999 is was: CRC 61.8%, breast 88.8%, lung 23.1%, NHL-B 67.7%, and MM 43.4%. Conclusions Comparative results have shown a 5% overall improvement in RS for the 3 solid tumours, a significant increase in MM and a stabilization in the NHL-B.
