Cancers of the Lung
CANCER OF THE LUNG
|CENTRALLY ARISING||PERIPHERALLY ARISING|
|Small Cell Carcinoma – linked to smoking, can produce ACTH and ADH, may be linked to Lambert-Eaton syndrome
Squamous Cell Carcinoma – linked to smoking and the production of ectopic PTrP.
|Adenocarcinoma – is the most common peripherally arising cancer of the lung.
Large Cell Carcinoma – is an undifferentiated carcinoma of the lung.
Bronchioalveolar Carcinoma – this is the lung cancer that is not thought to be related to smoking
Lung cancer can cause a wide array of symptoms (aside from cough, hemoptysis, wheezing, bronchial obstruction). The most common symptoms that can arise from lung cancer are:
– Pancoast’s tumor (a carcinoma that originates in the apex of the lung and can compress the cervical sympathetic plexus, resulting in Horner’s syndrome)
– Superior vena cava syndrome
– Horner’s syndrome (Ptosis, Anhydrosis, Miosis)
– Paraneoplastic disorders (PTrP, ADH, ACTH)
– Recurrent laryngeal nerve symptoms (hoarseness)
