Any other information on results incl. tables

The history of the patient does not report any incident of acute beyllium disease.

Potenial causal exposures:

Asbestos: 0.8 "fibre years"

Be containing dusts (max. 2 %): 0.5 h/week over 18 years

Smoking: 63 - 100 "package years"

Applicant's summary and conclusion

Conclusions:
The BGFA accepts beryllium as cause for lung tumors only if the person has suffered from an acute beryllium disease before.
Executive summary:

The case of a former airplane mechanic with an adenocarcinoma T2 NX M1 (BRA), Stadium IV is discussed with regard to his professional exposure beryllium containing dusts. The exposure was deemed low and as there is no acute beryllium disease on record, the causality of beryllium was denied. Smoking is considered as cause.
