Major pulmonary embolism occurring insidiously over several weeks (subacute massive pulmonary embolism) has a high mortality and may not respond well to standard anticoagulant or thrombolytic treatment. A priming dose of plasminogen was used to enhance thrombolysis produced by a streptokinase infusion in five consecutive patients with subacute massive pulmonary embolism. In each patient a dramatic clinical improvement occurred with a substantial increase in pulmonary blood flow. All five patients survived to leave hospital. Malignant disease was the underlying cause of embolism in three patients, two of whom died of their malignant disease in the six months after treatment of their pulmonary embolism. The third patient with malignant disease had a choriocarcinoma; at least some of the pulmonary obstruction may have been tumour tissue but this obstruction was dramatically cleared by the treatment. The use of a combination of plasminogen with streptokinase should be considered in severely ill patients with subacute massive pulmonary embolism, particularly if other treatment, including streptokinase alone, has failed.

Malignant disease predisposes to deep venous thrombosis (DVT) or pulmonary embolism (PE) in several ways. One classical situation is that of DVT or PE with no apparent cause which may be the first sign of an occult cancer. In this domain, although the epidemiological data is well known, it is important to recognise the limitations of "blind" investigations. Another situation is more common. The patients have a diagnosed malignancy and thromboembolic disease is the main extra-cancer complication. The approach to this problem is changing, both in primary prevention where many trials have already reported encouraging results, and in the treatment after the event where classical therapeutic protocols are not always well adapted. Ancestral fears of the prescription of anticoagulants in cancer patients must cede to a more objective benefit/risk analysis which seems to be very favourable in some situations. Moreover, some publications have demonstrated a chance finding of a possible anticancer effect of antithrombotic agents.
