Role of dietary iodine and cruciferous vegetables in thyroid cancer: a countrywide case-control study in New Caledonia.

Exceptionally high incidence rates of thyroid cancer have been reported in New Caledonia, particularly in Melanesian women. To clarify the reasons of this elevated incidence, we conducted a countrywide population-based case-control study in the multiethnic population of Caledonian women. The study included 293 cases of thyroid cancer and 354 population controls.

Limb body wall complex and amniotic band sequence in sibs.

We report on a woman who gave birth consecutively to an infant with limb body wall complex (LBWC) and then to an infant with amniotic band sequence (ABS). This paper reviews the different etiological hypotheses and the classification problems for the amniotic band diseases. No maternal factors were found, but this clinical report suggests further research in this direction, as well as the need to look more closely at the relation between LBWC and ABS.

Alcohol drinking, tobacco smoking, and anthropometric characteristics as risk factors for thyroid cancer: a countrywide case-control study in New Caledonia.

Exceptionally high incidence rates of thyroid cancer are observed in New Caledonia, particularly in Melanesian women. To investigate further the etiology of thyroid cancer and to clarify the reasons of this elevated incidence, the authors conducted a countrywide population-based case-control study in this multiethnic population. The study included 332 cases with histologically verified papillary or follicular carcinoma (293 women and 39 men) diagnosed in 1993-1999 and 412 population controls (354 women and 58 men) frequency matched by gender and 5-year age group.

Pleural mesothelioma in New Caledonia: an acute environmental concern.

Background: In 1991, a relationship was established between excess cases of pleural cancer in New Caledonia and a traditional lime, called "Pö", to cover houses. Our study aimed to determine whether the Pö is the only cause of mesothelioma in New Caledonia.

Methods: Eligible cases were pleural tumor diagnosed between 1984 and 2002 with histological diagnosis of mesothelioma.

Time trends and geographic variations for thyroid cancer in New Caledonia, a very high incidence area (1985-1999).

Thyroid cancer incidence in New Caledonia is the highest reported in the world and is approximately 10-fold higher than in most developed countries. We describe the incidence patterns in this country according to histological and sociodemographic characteristics to give clues about potential etiologic factors. Another objective is to see whether the incidence figures are related to enhanced detection of small size carcinomas.

Role of goiter and of menstrual and reproductive factors in thyroid cancer: a population-based case-control study in New Caledonia (South Pacific), a very high incidence area.

Exceptionally high incidence rates of thyroid cancer have been reported for Melanesian women in New Caledonia (South Pacific). To investigate the occurrence of thyroid cancer in that country and to clarify the role of goiter and hormonal factors in that disease in women, a countrywide population-based case-control study was conducted in 1993-1999. The study included 293 cases, identified through pathology registers and whose thyroid cancer was verified histologically, and 354 population controls.
