A new monoclonal antibody (PE‐10) raised against components of pulmonary surfactant has been assessed for its ability to distinguish primary from secondary carcinomas in the lung. We applied this antibody to a series of 107 primary lung carcinomas, 40 adenocarcinomas of other sites, and 26 cases of adenocarcinoma metastatic to lung and pleura. Of the primary lung carcinomas, all the non‐mucinous bronchiolo‐alveolar carcinomas were positive whereas all the mucinous cases were negative; 60% of other types of adenocarcinoma were positive and 10% of large cell undifferentiated carcinomas, 20% of small cell carcinomas and 40% of atypical carcinoids also showed focal positivity. Squamous cell carcinomas were all negative. Adenocarcinomas of the breast, kidney, large bowel and ovaries were all negative, as were all 26 cases of adenocarcinoma metastatic to the lung and pleura. We conclude that this antibody is highly specific and moderately sensitive for primary tumours of the lung.
