[Over-estimation of incidence in the Quebec Tumor Registry 1981-1982].
Since 1981, the Quebec Tumor Registry (FTQ) is using form AH-101P which is filled out for all patients seeking care in Quebec hospitals. From a list of 8,000 names in 1981-82, we have found that 4.8% was constituted of cases reported 2, 3 and 4 times. In two major hospitals, we have checked 71 medical records of patients reported more than once to FTQ using the AH-101P form with what was found in the hospital records. Only 6 multiple cancers (8.5%) were found. All other cases were constituted of invasions, infiltrations or metastasis. It is concluded that, despite the new procedure, cancer incidence is still overestimated in FTQ in 1981-82 but this problem should disappear in the near future.
