Aims In the time period near to the diagnosis of a new cancer, other tumors (synchronous cancers), especially slow-growing tumors, may be detected because several diagnostic examinations are performed. The frequency of synchronous in comparison with metachronous carcinomas has been evaluated in a population-based series of multiple primary cancers. Methods The case series of multiple primary cancers of the Tuscany Tumor Registry, incident during the period 1985-1991 was analyzed. For each site of a second independent tumor, the proportions of synchronous (diagnosed within 2 months of the first primary) and metachronous cancers were compared with the mean distribution (all sites except the specific one). Results During 1985-1991, 1095 patients had two independent tumors diagnosed; 216 were synchronous. The proportion of synchronous compared to metachronous cancers was significantly higher for bladder, prostate and renal cell carcinomas; it was significantly lower for lung cancer. When cancers following skin epitheliomas were evaluated, only the proportion of synchronous skin cancers was significantly increased. Conclusions Silent slow-growing tumors are suspected to be more frequent in patients with prostate, bladder or renal cell carcinomas. In fact, they were most frequently diagnosed during ascertainment for another cancer. When few examinations were performed, as after the diagnosis of a skin epithelioma, no difference between metachronous and synchronous cancers was evident, except for skin.

Multiple Primary

Population-based cancer registry data provide a key epidemiological resource for monitoring cancer in defined populations. Validation of the data variables contributing to a common data set is necessary to remove statistical bias; the process is currently performed centrally. An ontology-based approach promises advantages in devolving the validation process to the registry level but the checks regarding multiple primary tumours have presented a hurdle. This work presents a solution by modelling the international rules for multiple primary cancers in description logic. Topography groupings described in the rules had to be further categorised in order to simplify the axioms. Description logic expressivity was constrained as far as possible for reasons of automatic reasoning performance. The axioms were consistently able to trap all the different types of scenarios signalling violation of the rules. Batch processing of many records were performed using the Web Ontology Language application programme interface. Performance issues were circumvented for large data sets using the software interface to perform the reasoning operations on the basis of the axioms encoded in the ontology. These results remove one remaining hurdle in developing a purely ontology-based solution for performing the European harmonised data-quality checks, with a number of inherent advantages including the formalisation and integration of the validation rules within the domain data model itself.
