- Background: With a population-based setting, high coverage and accurately recorded data, the validity of a register is guaranteed. The South-East Region Prostate Cancer relies on the National Cancer Register as a basic source of data, thereby ensuring a high coverage of the corresponding geographic area. To assess the reproducibility of the data recorded a random sample of the cases were reviewed a second time and compared to the original recording. Material and methods: The South-East Region Prostate Cancer Register was started in 1987. In addition to the basic data acquired from the Swedish National Register, it also includes tumour stage, grade, treatment and, since 1992, PSA. In the first stage of quality assessment 10 cases for each of the years 1987-1996 from Link÷ping University Hospital were randomly selected for two independent recodings according to the same protocol as the original registration. In the second step 10 cases each for the same years from the remaining 8 hospitals in the region were selected for a single recoding. Results: No systematic deviations were seen between the two independent recodings from Link÷ping, a single recoding was therefore considered sufficient for assessing the reproducibility of the data from the remaining hospitals in the region. The Kappa values for agreement between the original registration and the single recoding ranged from 0.589 to 0.869. Conclusion: The population-based setting and high coverage guarantees the external validity of the register. The internal validity is ensured by the high reproducibility shown in the present study.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Hot flashes are as common in men who have been castrated due to prostate cancer as hot flashes are in women after menopause. The symptom can cause significant discomfort for a considerable length of time. The hot flashes are most likely caused by a reduction in sex-hormone levels, which, in turn, causes an instability in the hypothalamic thermoregulatory center. Calcitonin gene-related peptide is involved in menopausal hot flashes in women and possibly also in castrated men. The mainstays of treatment for castrated men with hot flashes remain estrogens, progesterone, and cyproterone acetate, each of which has different side effects. Other treatments for hot flashes include clonidine and antidepressants and, according to one uncontrolled study, electrostimulated acupuncture. Nonetheless, there is a need for more effective and less toxic treatments. In this review, we will discuss the prevalence, duration, distress, physiology, and treatment options of hot flashes in men subjected to castration therapy due to prostate cancer.
