Trends in incidence and prognosis of the histological subtypes of lung cancer in North America, Australia, New Zealand and Europe

Background: Since the incidence of the histological subtypes of lung cancer in industrialised countries has changed dramatically over the last two decades, we reviewed trends in the incidence and prognosis in North America, Australia, New Zealand and Europe, according to period of diagnosis and birth cohort and summarized explanations for changes in mortality. Methods: Review of the literature based on a computerised search (Medline database 1966-2000). Results: Although the incidence of lung cancer has been decreasing since the 1970s/1980s among men in North America, Australia, New Zealand and north-western Europe, the age-adjusted rate continues to increase among women in these countries, and among both men and women in southern and eastern Europe. These trends followed changes in smoking behaviour. The proportion of adenocarcinoma has been increasing over time; the most likely explanation is the shift to low-tar filter cigarettes during the 1960s and 1970s. Despite improvement in both the diagnosis and treatment, the overall prognosis for patients with non-small-cell lung cancer hardly improved over time. In contrast, the introduction and improvement of chemotherapy since the 1970s gave rise to an improvement in - only short-term (<2 years) - survival for patients with small-cell lung cancer. Conclusions: The epidemic of lung cancer is not over yet, especially in southern and eastern Europe. Except for short-term survival of small cell tumours, the prognosis for patients with lung cancer has not improved significantly. Copyrigh

Rising incidence of breast cancer among female cancer survivors: implications for surveillance.

The number of female cancer survivors has been rising rapidly. We assessed the occurrence of breast cancer in these survivors over time. We computed incidence of primary breast cancer in two cohorts of female cancer survivors with a first diagnosis of cancer at ages 30+ in the periods 1975–1979 and 1990–1994. Cohorts were followed for 10 years through a population-based cancer registry. Over a period of 15 years, the incidence rate of breast cancer among female cancer survivors increased by 30% (age-standardised rate ratio (RR-adj): 1.30; 95% CI: 1.03–1.68). The increase was significant for non-breast cancer survivors (RR-adj: 1.41, 95% CI: 1.04–2.75). During the study period, the rate of second breast cancer stage II tripled (RR-adj: 3.10, 95% CI: 1.73–5.78). Non-breast cancer survivors had a significantly (P value=0.005) more unfavourable stage distribution (62% stage II and III) than breast cancer survivors (32% stage II and III). A marked rise in breast cancer incidence among female cancer survivors was observed. Research to optimise follow-up strategies for these women to detect breast cancer at an early stage is warranted

Long-term prognosis of breast cancer: An analysis of 462 patients in a general hospital in south east Netherlands

In this study the long-term prognosis was analysed of all 462 consecutive female breast cancer patients who were diagnosed and carefully staged between 1970 and 1980 in a 600-bed community hospital in Eindhoven, south east Netherlands. Follow-up of recurrence and causes of death was obtained until 1 January 1993. Observed survival rates at 5, 10 and 20 years were 66%, 45% and 32%, respectively, and the corresponding breast cancer-specific survival rates were 71%, 54% and 44%. The yearly risk for a recurrence of breast cancer after treatment steadily decreased from 10% the first year to 1% after 10 years. In a multivariate survival analysis both tumour size and nodal status appeared to be equally important prognostic factors in the first 5 years after diagnosis. After 5 years only tumour size had independent prognostic value, which was not significant any more after 10 years. In patients with a tumour size ⩽ 2 cm and without lymph node involvement at diagnosis, the risk for a recurrence was found to be negligible after 10 years. Those patients may be considered cured, although a search for early diagnosis of a second primary breast cancer in this group is still advisable

Socioeconomic status and breast cancer survival in the southeastern Netherlands, 1980-1989

Socioeconomic differences in breast cancer survival in the southeastern Netherlands between 1980 and 1989 were studied (n = 3928), as was the impact of prognostic factors (stage at diagnosis, morphology, and treatment) on such differences. An area-based measure of Socioeconomic status (SES) in five groups, based on the postcode of residence at the time of diagnosis, was used. In univariate analyses the relative survival rate was used to correct for causes of death other than breast cancer. The measure of outcome in multivariate analyses was the hazard ratio. The results of both univariate and multivariate analyses suggested a small survival advantage for the higher SES groups. In a mode

Incidence, Prevalence and Future Trends of Primary Basal Cell Carcinoma in the Netherlands

Abstract: Basal cell carcinoma (BCC) incidence rates are increasing worldwide. This study’s objective was to estimate the occurrence of BCC in the Netherlands in terms of incidence and prevalence. Data on first primary carcinomas were retrieved from the Eindhoven Cancer Registry and extrapolated to the Dutch population. Extrapolated data showed a total of 444,131, histologically confirmed cases in the Netherlands between 1973 and 2008. During this period, age-adjusted incidence rates (European Standard Population) increased approximately three-fold from 40 to 148 per 100,000 in males and from 34 to 141 in females. Lifetime risk of BCC was 1 in 5–6 for Dutch citizens. Disease prevalence in the Netherlands was 1.4% and almost four times higher than this (5.4%) in the oldest age group (age 65 years or more). Predictions of future trends showed no signs of a plateau in the number of cases. These estimates should urge Dutch policymakers to provide solutions for the growing group of patients with BCC
