SCetuximab
Interstitial pneumonia: 2 case reportsTwo men, aged 61 and 65 years, developed interstitial
pneumonia during treatment with cetuximab.The younger man had mesopharynx squamous cell
carcinoma, and the older man had tonsilar squamous cellcarcinoma and oesophageal adenocarcinoma. Theyreceived cetuximab post-radiotherapy, comprising 6 cyclesof 400mg with a 600mg loading dose in the younger man,and a last dose of 450mg in the older man [routes notstated; not all dosages stated]. They presented with fever,cough and shortness and breath 5 or 6 weeks after startingcetuximab, respectively; the younger man also had lungconsolidation. Both men also had skin rashes consistentwith cetuximab-associated skin toxicity. CT scanningrevealed ground-glass changes in their lungs. The youngerman developed chemotherapy-related febrile neutropeniaand an Enterobacter cloacae infection at his percutaneousendoscopic gastrostomy site, and received cefepime andertapenem. The older man developed nosocomialpyelonephritis, and received empiric ceftriaxone.
The men received antibiotics and prednisone. Chest x-ray results for the younger man were almost normal 7 daysafter starting prednisone, and he was discharged 3 dayslater. The older man’s symptoms improved within 5 daysafter starting prednisone. However, he subsequentlydeveloped gastrointestinal bleeding, severe acuterespiratory distress syndrome and multiple organdysfunction syndrome, and died. Autopsy revealedbronchitis with diffuse alveolar dysfunction, lungmetastases, thrombotic endocarditis of his mitral valve, andischaemic infarction of his spleen, kidney, brain and heart[cause of death not stated].
