Earlier literature suggested there may be a seasonal rhythm of onset of Hodgkin's disease.
This issue has been re-examined using population-based prospectively-collected data with high ascertainment levels.
The Data Collection Study (DCS) of the Leukaemia Research Fund (LRF) Centre for Clinical Epidemiology (University of Leeds) generated the information used, which was based on a population of 13.5 million - about one quarter of England and Wales - over 10 years.
The RYE histopathological classification was employed.
The findings show that in patients with nodular sclerosing histopathology there was a highly significant circannual rhythm with a low amplitude (extent of seasonal variation) and a peak in March.
A significant, but different, rhythm with a high amplitude and a peak in August was found in lymphocyte predominant Hodgkin's disease.
However, this finding is less certain, due to smaller numbers and a lower significance level.
The main conclusion is that there is a highly significant seasonality in nodular sclerosing Hodgkin's disease.
The findings provide further evidence that nodular sclerosing and lymphocyte predominant may be two different diseases, The differing seasonality rhythms may provide aetiological clues.
