Diagnosis Score of Lortholary et al for a Paraneoplastic Syndrome

Does the patient have a tumor?

Can the findings be explained by a direct effect of the tumor or the metastases?

Is there an alternative explanation for the findings that does not involve the tumor?

Does the severity of symptoms vary with the tumor burden (worse with tumor progression, better with regression)?

Has there been a previous report of these clinical findings being associated with this tumor?
