•Considered only if •After primary treatment (Sx, ChT, RT) •curative•no residual evidence of tumour
• Few exceptions •Chronic lymphoid malignancies•Early prostate cancer

•CT of whole abdomen •resolution of lymphadenopathy •F/U q 3 months
•18F-FDG PET : negative study
•Condition improved>>returned to flying •Class 1 OML
Re-evaluation after 4th cycle

Discussion•Annual medical examination is not enough
•Accurate assessment of ALCL is challenging
•Limit data in adult patients
![Page 19: Return To Fly After Anaplastic Large Cell Lymphoma …Return To Fly After Anaplastic Large Cell Lymphoma a Case Report Manoj Plaingam MD,MPHAuthorized Medical Examiner Institute of](https://reader034.fdocuments.net/reader034/viewer/2022042023/5e7b6eae9e47fa7ecd4a3366/html5/thumbnails/19.jpg)
Discussion•Weighting time period to re-certification
•Relapse•Malaise, Fatigue, Lymphoid swollen
•Symptomatic relapse >>uncommon
•Sudden incapacitation is rare.

Conclusion
•The key to certification of lymphoma •Fair and Objective•Strong and clear in policy•Multidisciplinary•Need Scientific data support
•Should be audited by board of specialist
