Paraneoplastic syndromes for the primary care physician

To summarize, we have reviewed the major endocrine, hematologic, neurologic, dermatologic, and miscellaneous paraneoplastic syndromes. These entities are of great importance to the primary care physician because, when recognized, they can permit early diagnosis of the neoplasm. Further, treatment can afford palliation of symptoms. We can expect more definite identification of the causes of the paraneoplastic syndromes in the future because more of the substances that are released by tumors will be identified and analyzed. We need to watch with anticipation for the development of specific treatments for the paraneoplastic syndromes as the causes are identified.
