“…Still, there has been a rapid rise in melanoma incidence not only in adults but also in adolescents during the later half of the 20th century. [10][11][12][13][14][15] In a previous report, we found that the incidence of CMM in Sweden in individuals aged 12-19 years doubled in 1983-1992 compared with [1973][1974][1975][1976][1977][1978][1979][1980][1981][1982]. 10 In 1992, CMM was the fifth most common cancer in 15-19 year old Swedish adolescents, constituting 10% of all cancer cases in this age group.…”

The incidence of cutaneous malignant melanoma rose rapidly in teenagers in Sweden during 1973Sweden during -1992, while it remained low in younger children. To study the further trends and characteristics of melanoma in this young population, data on all cases in individuals under 20 years of age reported to the Swedish Cancer Registry during [1993][1994][1995][1996][1997][1998][1999][2000][2001][2002], and the corresponding pathology reports were examined. Seventy-nine cases were reported to the Registry. There were 24 males and 55 females. Most melanomas occurred on the trunk followed by the legs in both genders. The median tumor thickness was 0.8 mm. Children under age 15 had thicker melanomas than individuals aged 15-19. Superficial spreading melanoma was the most common histological subtype (43/78, 55%). The melanoma-specific 5-year survival rate was 90%. During 1993-2002, the age-standardized incidence fell to 3.6/million from 5.0/million in 1983-1992 (RR 0.74, 95% CI 0.58-0.92). The most pronounced decrease was for melanomas on the trunk in boys and on the legs in girls. The incidence for 15-19-year-old boys peaked for the cohort born between 1968 and 1972 and for girls between 1973 and 1977. The decrease in incidence may be a result of public health campaigns aiming at reducing sun exposure in childhood. A contributing effect from an increased immigration of individuals with darker complexions and at a lower melanoma risk is probable. ' 2007 Wiley-Liss, Inc.

RESUMO ABSTRACTNeoplasias de cabeça e pescoço; Prevalência; Criança; Adolescente.Head and neck neoplasms; Prevalence; Child; Adolescent. Objecti ve: To verify the prevalence of malignant tumors of the head and neck region in infant and juvenile pati ents registered at the Cancer Hospital of Pernambuco, Recife, PE, Brazil. Method: This study was a retrospecti ve and cross-secti onal investi gati on in which 126 pati ent records were reviewed between 1995 and 2000. Informati on on the variables gender, age group, primary anatomic localizati on and histological type was recorded and transcribed to a specifi c chart. The data were analyzed using the Stati sti cal Package for Social Sciences (SPSS) soft ware, version 13.0. Results: 23 cases (18.3%) were malignant tumors aff ecti ng the head and neck region of children and adolescents. The age range was between 2 and 17 years (mean age 13 years), and most pati ents were aged 13 to 18 years (65.2%). There was a predominance of male pati ents (65.2%), with a male-tofemale rati o of 1.8:1. The nasopharynx was the most aff ected anatomic region (21.7%), followed by the paroti d gland and oral cavity (17.4%). The most frequent histological types were those derived from the epithelial lineage (48%), among which the undiff erenti ated carcinoma (13%). Among the tumors derived from the mesenchymal ti ssue, the most frequent were rhabdomyosarcoma (30%) and lymphoma (17%). DESCRITORES KEYWORDS Conclusion:Research on infant and juvenile cancer in Brazil address the populati on basis and the mortality in a general manner. Data on the prevalence of malignant tumors of the head and neck region in children and adolescents are sti ll scarce. Further studies on this area should be encouraged because they are important in the elaborati on and planning of nati onal or regional public policies and health programs.

Trends in childhood acute lymphoblastic leukemia in Western Australia, 1960–2006

Increases in the incidence of childhood acute lymphoblastic leukemia (ALL) have been reported in some countries, while other reports from similar geographical regions have indicated stable rates. The reasons for the discrepancies have been debated in the literature, with the focus on whether the observed increases are “real” or an artifact resulting from improvements in diagnosis, case ascertainment and population coverage over time. We used population‐based data from Western Australia to investigate trends in the incidence of childhood ALL between 1960 and 2006. Age‐standardized incidence rates (ASRs) and rate ratios (indicating annual percent change) were estimated using Poisson regression. Between 1960 and 2006, the ASR was 3.7 per 100,000 person‐years, with an annual percent increase of 0.40% (95% CI: −0.20, 1.00). Between 1982 and 2006, the ASR was 3.8, with an annual percent increase of 0.80% (95% CI = −0.70 to 2.30). This increased to 1.42% (95% CI: −0.30, 3.0) when a sensitivity analysis was undertaken to assess the effect of excluding the final 2 years of data. Annual increases of 3.7% (95% CI: −0.50, 8.00) among children aged 5–14 years, and of 3.10% (95% CI: 0.50, 5.70) in girls, were observed for this latter period. These results were supported by national Australian incidence data available for 1982–2003. There may have been a small increase in the incidence of ALL since 1982 among girls and older children, but an overall increase appears unlikely. No impact of folate supplementation or fortification is apparent. © 2007 Wiley‐Liss, Inc.
