ABSTRACT
Congenital malformations and cancer may share common etiological factors and the association between nonsyndromic cleft lip and/or palate (NSCL/P) and cancers has been observed in different studies. The objective of this study was to evaluate the frequency of cancer in relatives of patients with NSCL/P. This investigation was a cross-sectional, case-controlled study, evaluating 358 patients with NSCL/P treated at a Referral Center for craniofacial deformities (case group) and 358 patients without craniofacial alterations (control group). Information concerning the gender, age and family history of cancer in first-degree relatives for both groups was obtained. The frequency of cancer was 6.4% (n=46) in the studied population, with 18 subjects in the case group (5%) and 28 (7.8%) in control. In both groups, the most frequently reported cases were those of breast, colorectal, stomach, prostate and uterus cancers, but there was no association between the two groups. There was no association with a family history of cancer among the first-degree relatives (odds ratio=0.62; 95% IC 0.34 to 1.15), neither when the analysis was made by type of cancer. In conclusion, both epidemiological and genetic studies have suggested common etiological factors for NSCL/P and cancer. However, in this population-based study, no association between cancer and NSCL/P could be confirmed.
RESUMO
Malformações congênitas e o câncer podem compartilhar fatores etiológicos comuns e a associação entre fissura labial e/ou palatina não sindrômica (FL/PNS) com o câncer tem sido observada em diferentes estudos. O objetivo foi avaliar a frequência de câncer em parentes de pacientes com FL/PNS. Conduziu-se um estudo transversal, do tipo caso-controle, avaliando 358 pacientes com FL/PNS, assistidos em um centro de referência para tratamento de deformidades craniofaciais (grupo caso) e 358 pacientes sem alterações congênitas (grupo controle). Foram obtidas informações a respeito de gênero, idade e histórico familiar de câncer em parentes de primeiro grau para ambos os grupos. A frequência de câncer na população estudada foi de 6,4% (n=46), com 18 históricos no grupo caso (5%) e 28 (7,8%) no grupo controle. Em ambos os grupos, os principais cânceres relatados foram de mama, colorretal, estômago, próstata e útero, mas não houve associação quando comparados os dois grupos. Também não houve associação de histórico familiar de câncer em parentes de primeiro grau (odds ratio=0,62; 95% IC 0,34 a 1,15), nem quando a análise foi feita pelo tipo de câncer. Estudos epidemiológicos e genéticos têm sugerido fatores etiológicos comuns entre FL/PNS e câncer. Contudo, na população do presente estudo, não se verificou a associação entre câncer e FL/PNS.
