Pulmonary cancer has one of the highest mortality rates of cancer today. Especially one form of lung cancer has increased over the last years, adenocarcinoma with the subtype brochioloalveolar carcinoma (BAC). It has been suggested that lung cancer in cats could make a good model for research on BAC. The “Lung-digit syndrome” is an often described type of lung cancer in cats. The syndrome has also been seen in humans. The lung tumor metastasizes to the distal phalanges and sometimes it is the first symptom the patients exhibits. This type of metastasis often means a poor prognosis for the patient. In a comparison between human and feline adenocarcinoma you can see similarities in histology, spread and sex distribution. When you compare human and feline BAC you see similar histological types but cats have too low incidence of BAC to yield a good research material. Metastases to the phalanges are more common in cats than humans. This may give an opportunity to study how cancer spreads.
