Mycosis fungoides: epidemiologic observations
Cancer Treatment Reports
|April 1, 1979
Summary
This study explored the causes of mycosis fungoides (MF), a skin cancer. Findings suggest potential links between MF and prior allergies, skin infections, sun sensitivity, family history of cancers, and specific manufacturing jobs.
Area of Science:
- Dermatology
- Oncology
- Epidemiology
Background:
- Mycosis fungoides (MF) is a type of cutaneous T-cell lymphoma.
- The etiology of MF remains incompletely understood, necessitating further investigation into potential risk factors.
Purpose of the Study:
- To investigate the etiology of mycosis fungoides (MF).
- To identify potential environmental and occupational risk factors associated with MF development.
Main Methods:
- Analysis of a multi-hospital, pathologically verified clinical series of MF cases.
- Examination of US mortality statistics at the county level from 1950-1975 (excluding 1972).
Main Results:
- Cases showed a high frequency of antecedent allergies, fungal and viral skin infections, and sun sensitivity.
- Familial aggregation of lymphoma and leukemia was noted.
- Mortality data indicated a predominance among males, nonwhites, and northeastern US residents.
- Excessive MF mortality rates were observed in counties with specific manufacturing industries (petroleum, metal, machinery, printing).
Conclusions:
- Potential associations between MF and antecedent allergies, infections, sun sensitivity, and family history warrant further study.
- Occupational exposures in certain manufacturing sectors may contribute to MF etiology.
- Geographic and demographic patterns suggest environmental influences on MF incidence.
