TL;DR: It is confirmed that sun exposure prior to diagnosis of melanoma is associated with improved survival, and intermittent sun exposure had a tendency to be inversely associated with the risk of death.

TL;DR: Comparing repeated self-reports of weight, height, derived body mass index, and waist and hip circumferences, obtained between 1999 and 2008, with clinical measurements taken in 2008 provides new evidence that self-reported anthropometric variables remain suitable for use in analyses of associations with disease outcomes in cohort studies over at least a decade of follow-up.
Abstract: In prospective epidemiological studies, anthropometry is often self-reported and may be subject to reporting errors. Self-reported anthropometric data are reasonably accurate when compared with measurements made at the same time, but reporting errors and changes over time in anthropometric characteristics could potentially generate time-dependent biases in disease-exposure associations. In a sample of about 4000 middle-aged UK women from a large prospective cohort study, we compared repeated self-reports of weight, height, derived body mass index, and waist and hip circumferences, obtained between 1999 and 2008, with clinical measurements taken in 2008. For self-reported and measured values of each variable, mean differences, correlation coefficients, and regression dilution ratios (which measure relative bias in estimates of linear association) were compared over time. For most variables, the differences between self-reported and measured values were small. On average, reported values tended to be lower than measured values (i.e. under-reported) for all variables except height; under-reporting was greatest for waist circumference. As expected, the greater the elapsed time between self-report and measurement, the larger the mean differences between them (each P < 0.001 for trend), and the weaker their correlations (each P < 0.004 for trend). Regression dilution ratios were in general close to 1.0 and did not vary greatly over time. Reporting errors in anthropometric variables may result in small biases to estimates of associations with disease outcomes. Weaker correlations between self-reported and measured values would result in some loss of study power over time. Overall, however, our results provide new evidence that self-reported anthropometric variables remain suitable for use in analyses of associations with disease outcomes in cohort studies over at least a decade of follow-up.

TL;DR: Recent developments in the national cancer control agenda have included an increasing emphasis on outcome measures, with short-term cancer survival an operational measure of variation and progress in cancer control giving strong support for this strategy.

TL;DR: The data suggest that Kaposi's sarcoma is caused by a sexually transmissible agent which was introduced into the British homosexual population mainly from the United States.
Abstract: OBJECTIVE--To determine whether the risk of Kaposi9s sarcoma in patients with AIDS is increased by sexual contact with groups from abroad with a high incidence of Kaposi9s sarcoma. DESIGN--Analysis of risk of Kaposi9s sarcoma in patients with AIDS, according to country of origin of their sexual partners. SETTING--United Kingdom. PATIENTS--2830 patients with AIDS reported to the Communicable Disease Surveillance Centre and the Communicable Disease (Scotland) Unit up to March 1990, of whom 566 had Kaposi9s sarcoma. MAIN OUTCOME MEASURES--Percentage of patients with AIDS who had Kaposi9s sarcoma. RESULTS--537 of 2291 homosexual or bisexual men (23%) with AIDS had Kaposi9s sarcoma; 10% (14/135) of the men and women who acquired HIV by heterosexual contact had Kaposi9s sarcoma. None of the 316 subjects who acquired HIV through non-sexual routes had Kaposi9s sarcoma. Kaposi9s sarcoma was more common among homosexual men whose likely source of infection included the United States (171/551, 31%) or Africa (9/34, 26%) than among those infected in the United Kingdom (119/625, 19%) (p less than 0.05). CONCLUSION--The data suggest that Kaposi9s sarcoma is caused by a sexually transmissible agent which was introduced into the British homosexual population mainly from the United States [corrected].

TL;DR: The objective of this study was to evaluate the use of the cell cycle–related proteins p27kip1 and MIB‐1 as prognostic indicators of survival in PMMs.
Abstract: BACKGROUND
Pleural malignant mesothelioma (PMM) is a rare and highly aggressive tumor, whose development is strictly related to occupational exposure to asbestos. The prognosis of PMM is generally poor (median survival, 4–12 months), but a few have a relatively long survival. The objective of this study was to evaluate the use of the cell cycle–related proteins p27kip1 and MIB-1 as prognostic indicators of survival in PMMs.
METHODS
Of 621 PMMs, the authors selected 27 cases with a relatively long-term survival (> 24 months) and a control group of 36 PMMs having a shorter (usual) survival (< 24 months).
RESULTS
The expression of the p27kip1 was significantly higher in the long-term survival group compared with the control (short survival) group (81.41% vs. 31.94%; P < 0.0001). The PMMs of epithelioid histotype had a significantly higher p27kip1 immunoreactivity compared with those of biphasic type (59.24% vs. 38.94%; P = 0.02). In agreement with the data in the literature, the proliferative activity (as detected by MIB-1 immunoreactivity) was significantly higher in short than long survival PMMs (43.53% vs. 14.11%; P < 0.0001) and in the biphasic histotype than in the epithelioid type (43.19% vs. 26.02%; P = 0.006).
CONCLUSIONS
The combined expression of high/low p27kip1 and low/high Ki-67 values identified with 100% specificity and sensitivity long versus short survivors. p27kip1 represents a reliable additional predictive factor for PMMs and a useful marker to identify patients having a more favorable prognosis.
