Anticancerdrug-induced cardiac toxicity has been recognized since the introduction and widespread use of the anthracycline derivative doxorubicin in the 1970's. Risk factors for cardiac toxicity have increased along with the development of multidisciplinary therapy, high-dose combination chemotherapy, and molecular-targeted therapy. Cardiac toxicity is now recognized as a common adverse effect. Cardiac toxicity as an adverse event caused by molecular targeted agents such as trastuzumab may lead to irreversible cardiac dysfunction. The developmental mechanism of cardiac toxicity has not been fully defined for any agent. At present, practical strategies include the evaluation of cardiac function before treatment and the monitoring of cardiac function during treatment to determine whether chemotherapy should be administered or withdrawn. Edema caused by molecular-targeted agents such as imatinib is considered a relatively new adverse event. Prompt and accurate differential diagnosis of edema is essential, followed by appropriate action. Currently, however, only symptomatic treatment is available. Future studies should attempt to elucidate the mechanisms of cardiac toxicity and edema associated with molecular-targeted agents, as well as develop new treatment strategies.

The development of digital oedema, adhesion formation, and resistance to digital motion at days 0, 3, 5, 7, 9 and 14 after primary flexor tendon repairs using 102 long toes of 51 Leghorn chickens was studied. Oedema presented as tissue swelling from days 3 to 7, which peaked at day 3. After day 7, oedema was manifest as hardening of subcutaneous tissue. The degree of digital swelling correlated with the resistance to tendon motion between days 3 and 7. At day 9, granulation tissues were observed around the tendon and loose adhesions were observed at day 14. Resistance to digital motion increased significantly from day 0 to day 3, but did not increase between days 3 and 9. The early postoperative changes appear to have three stages: initial (days 0-3, increasing resistance with development of oedema), delayed (days 4-7, higher resistance with continuing oedema) and late (after day 7-9, hardening of subcutaneous tissue with development of adhesions).
