Objective: We report on the incidence and the gender, age, and ethnic distribution of sarcomas diagnosed between 1980 and 2008 in the multi-ethnic Republic of Suriname.

Methods: Total and average yearly number of cases, crude rates, as well as relevant population data were derived from the records of the Pathologic Anatomy Laboratory and the General Bureau of Statistics, respectively, and stratified according to gender, age groups 0-19, 20-49 and 50+ years, and the largest ethnic groups (Hindustani, Creole, Javanese and Maroons).

Results: Between 1980 and 2008, 258 sarcomas were diagnosed in Suriname, ie at a frequency of nine per year and an annual rate of two per 100 000.

In this study, we describe the incidence, treatment, and outcome of breast cancer (BC) during the period 1994-2003 in the South-American country of Surinam and compare these with those of BC in the Netherlands. Pathology reports and hospital charts from all BC cases diagnosed between 1994 and 2004 were retrieved from Surinam's single pathology laboratory and its five hospitals. Data on demographics, tumor characteristics, treatment, and follow-up were gathered.

Multiple human papilloma virus (HPV) infections have been detected in cervical cancer. To investigate the significance of multiple HPV infections, we studied their prevalence in cancer samples from a low-risk (Dutch) and a high-risk (Surinamese) population and the correlation of HPV infection with tumor cell aneuploidy. SPF(10) LiPA was used for HPV detection in formalin-fixed cervical carcinoma samples from 96 Dutch and 95 Surinamese patients.

Incidence rates of cervical cancer and its precursors vary considerably, with the highest rates found in developing countries. Differences are influenced by endogenous and exogenous factors. Comparing cytologic abnormality incidence rates from a high-risk population in the original high-risk area, with those of women from this high-risk population who have immigrated to a low-risk area could give insight in the significance of endogenous versus environmental factors.

Objective: To determine the prevalence of cytologic abnormalities in cervical smears from women attending the first organized screening program in Suriname and to compare the prevalences in 4 Surinamese ethnicities with different cervical carcinoma incidences.

Study Design: Cervical scrapes were taken from women with 4 different ethnicities: Maroons, Amerindians, Javanese and Hindustani. Papanicolaou staining and cytologic screening were performed on 807 cervical smears.
