Mycosis fungoides: an Australian experience.

Analysis was undertaken of 107 patients with mycosis fungoides who presented to St. Vincent's Hospital, Melbourne, during 1977-95. The mean age at diagnosis (55 years) was significantly older than the mean age of onset of symptoms (48 years). The mean duration of follow-up was 7.7 years. Urban residence was over-represented in this group of patients and in those with mycosis fungoides recorded at the State Cancer Registry. Eighty-four per cent were diagnosed at Stage I or II of the disease. Presentation with disease more advanced than Stage I was more likely to be found in males. Disease localized only to the trunk accounted for 45% of all patients. The mean number of biopsies prior to diagnosis was 1.4 but two-thirds were diagnosed at first biopsy. Almost 85% of patients had as their initial treatment either PUVA (44.9%), topical steroids (20.6%) or topical nitrogen mustard (18.7%) and 57% received only one or two treatment modalities during the period of the study. Stage at presentation was not related to the likelihood of clearance following treatment, recurrence, progression to a more advanced stage of disease or survival.
