Survival from cancer in the north region of Portugal: results from the first decade of the millennium.

The aim of this study was to evaluate net survival from cancer diagnosed during the period 2001/2010 in the north region of Portugal to identify the tumours that need actions to improve the outcomes. Data were retrieved from the North Region Cancer Registry of Portugal database. The top 20 cancer sites in adults were considered: oesophagus, stomach, colon, rectum, pancreas, liver, larynx, lung, skin melanoma, breast, cervix, corpus uteri, ovary, prostate, kidney, bladder, brain and central nervous system, thyroid, non-Hodgkin lymphoma and multiple myeloma. Net survival was estimated using the Pohar-Perme estimator. The effect of diagnosis period was evaluated using flexible parametric models adjusted for age and sex where appropriate. Thyroid and prostate cancers presented the best 5-year survival (>90%), whereas oesophagus, pancreas, liver and lung cancers the worst 5-year survival (
