RT Journal Article SR Electronic A1 Rohan, Pavel A1 Komenda, Stanislav T1 Contribution to the coincidence of malignant tumours and some allergic manifestations. JF Biomedical papers YR 2002 VO 146 IS 2 SP 95 OP 98 DO 10.5507/bp.2002.020 UL https://biomed.papers.upol.cz/artkey/bio-200202-0020.php AB Clinical observations during the past decades led us to the early empirical assumptions that adult patients affected by certain types of allergic manifestations may have a lower prevalence of malignant tumors. In order to test those observations as well as some contradictory reports, we conducted a retrospective study using 32 years of records and statistics of a medium-sized hospital (420 beds) at St. Mary's Hospital, a general, non-chronic, teaching hospital, affiliated with McGill University in Montreal. The study has been realized during two periods: (a) 1965-1989 and (b) 1990-1996.
