The hearts of eight patients aged 22 to 67 years (mean, 41 years) who died during or within 4 days of interleukin-2 (IL-2) based immunotherapy for treatment of renal cell carcinoma or melanoma were studied at necropsy. Death resulted from combined cardiorespiratory failure in two patients, sepsis in four patients, acute myocardial infarction in one patient, and myocarditis in one patient. Transmural left ventricular necrosis was present in one of the two patients with significant atherosclerotic coronary artery narrowing. Noninfectious myocarditis was present in five patients: the inflammatory infiltrate was lymphocytic in four and composed of a mixture of eosinophils and lymphocytes in one. Although treatment-related deaths associated with high-dose IL-2 therapy are uncommon (1.5% in 652 consecutive patients), the potential for significant myocardial ischemia or myocarditis exists, and careful monitoring for arrhythmias or myocardial failure is warranted.

This article is a case report of a 65-year-old white woman with a history of malignant melanoma, resected from her back in 1959. She presented 27 years later with right-sided heart failure and metastatic melanoma to her right ventricle. To the authors' knowledge, a large ventricular mass as the sole site of disease recurrence has not been described previously.

Sixty-five patients with advanced solid tumors were treated with 4'epi-doxorubicin, a new analogue of doxorubicin (DXR). Forty-three of 61 evaluable patients had not received previous chemotherapy and/or hormonal treatment. 4'Epi-doxorubicin has been administered at the dose of 75 mg/m2 i.v. once every 21 days, for a minimum of 2 courses. The pattern of acute toxicity was similar to that of DXR. Transient electrocardiographic abnormalities were found in about 50% of patients. The ratio of pre-ejection period to the left ventricular ejection time (PEP/LVET) increased within 1 h after drug injection and returned to near basal values after 24 h. Three patients received a total dose of more than 550 mg/m2, still maintaining a baseline PEP/LVET ratio near to pretreatment values. Up to now, no patient has developed clinical signs of heart failure. Partial responses were seen in patients with tumors generally sensitive to DXR such as breast carcinoma (6 of 14) and soft tissue sarcomas (2 of 6), and in patients with tumors generally resistant to DXR such as melanoma (1 of 9), colorectal carcinoma (3 of 18) and pancreatic carcinoma (1 of 2). These data suggest that 4'epi-doxorubicin may have a broader spectrum of antitumor activity than DXR.

A surgically confirmed primary leptomeningeal malignant melanoma (PLMM) discovered at the parietal region is reported in a 72-year-old male. He developed progressive right hemiparesis and speech disorders caused by a parietal large mass that simulated a growing meningioma. A well-defined, dark-black tumor was removed completely and was histopathologically diagnosed as a malignant melanoma. No melanomas were detected by systemic clinical and radiological examination, including dermatological and ophthalmologic examinations. Follow-up examination 18 months postoperatively showed no evidence of recurrence of the tumor. The patient gradually became bedridden probably because of decreased general activity possibly due to brain atrophy and died of cardiac failure without any evidence of recurrence. Because of the absence of other systemic localizations, we consider this melanoma as primary. A favorable outcome was obtained by surgical treatment alone.

High-dose ACNU followed by autologous bone marrow transplantation was administered alone or together with other agents such as cyclophosphamide, dacarbazine, carboquone or/and VP-16. The starting dose of ACNU was 200 mg/m2, with gradual escalation up to 400 mg/m2. Median duration of granulocytes of less than 100/mm3 and platelets of less than 30,000/mm3 was 4.5 days (range; 0-9) and 10.5 days (range; 0-43), respectively. Bacteremia occurred in 4 cases, but no case of pneumonia was encountered. Heart failure possibly due to the cyclophosphamide was noted in one case with arrhythmia. Out of 13 cases with measurable diseases, three patients with Hodgkin's disease, two patients with diffuse lymphoma, and one patient with follicular lymphoma attained a complete response. Partial response was obtained in two patients with non-Hodgkin's lymphoma. Two patients with melanoma and one with acute nonlymphocytic leukemia without measurable disease still remain disease-free.

Interleukin-2 (IL-2) is a cytokine with proven activity against metastatic renal cell carcinoma (RCC) and malignant melanoma (MM). The intravenous administration of high-dose IL-2 is limited by important cardiovascular side effects such as hypotension, fluid retention, arrhythmias, and myocardial ischemia, which often cause dose reduction and/or treatment withdrawal. The occurrence of these toxic events is not predicted by routine pretreatment examinations. The aim of the present study was to test the reliability of serial echocardiography in predicting subsequent cardiac adverse effects in patients undergoing IL-2 administration. In 19 patients (15 men, 4 women; median age: 51 years, range 27-71 years; 10 affected by metastatic RCC and 9 affected by MM) we performed two-dimensional and Doppler echocardiography before and immediately after 28 continuous intravenous infusions (CIVI) of IL-2 at the dose of 18 MIU/m2/day for 4 days. Left ventricular systolic function and the diastolic transmitral flow pattern were assessed before and after IL-2 administration. Significant changes of two indexes of left ventricular filling were noted: a decrease of the ratio of maximal flow velocity in early diastole to that in late diastole (E/A) (basal: 1.12 +/- 0.46, mean +/- SD; posttreatment: 0.83 +/- 0.27; p < 0.01) and an increase of the percentage of the atrial contribution to left ventricular filling (basal: 37.75 +/- 11.58%; posttreatment: 49.43 +/- 16.48%; p < 0.01). Eight major cardiovascular events causing IL-2 infusion withdrawal were observed (two ischemic electrocardiographic modifications, three grade III-IV hypotension, one atrial fibrillation, one pericardial effusion, one acute heart failure). These major cardiovascular events were observed more often when an abnormal basal E/A ratio < 1.0 (p < 0.05) was found. We conclude that Doppler transmitral flow pattern analysis before and subsequent to IL-2 infusion is a useful and easily available procedure for the monitoring of cardiac modifications during CIVI IL-2 administration. It might also predict a major cardiovascular event during IL-2 administration. Patients with basal E/A ratio < 1.0 should be more carefully monitored during treatment and/or should be treated with lower IL-2 doses to avoid cardiovascular toxicity.

A superficial spreading melanoma (Breslow thickness 0.4 mm) was diagnosed in a 65-year-old candidate for heart transplantation due to refractory end stage heart failure. After extensive review of the literature (USA and Europe), no clear guidelines about the management of candidates for transplantation with a previous diagnosis of melanoma were found. As this patient had a 5-year probability of survival higher than 95% and heart transplantation was necessary for saving his life, the final decision was to perform the transplantation. Unfortunately, the patient died of heart failure before a suitable heart became available. This case stresses the need for early and continuous dermatological evaluation of all candidates for solid organ transplantation. Clear guidelines for screening of skin cancer before transplantation are needed.

Adaptive physiologic buffers enable organisms to respond to environmental variation with appropriate plasticity. Modern humans have substantially remodeled their environment such that many interactions with the environment have become relatively discontinuous functions compared to the past. Examples include sunlight, temperature, and altitude. We propose that environmental discontinuity represents a Darwinian maladaptation and may promote disease by inducing buffer dysfunctions. Skin pigmentation is an adaptive, dynamic buffer that normalizes sunlight exposure to balance the potential harm of damaging rays with the importance of sunlight in driving systemic biologic functions such as melatonin and vitamin D. Due to lifestyle characteristics such as indoor-outdoor living, well-intended sun-avoidance campaigns, and inhomogeneous use of apparel and sunblock techniques, modern humans increasingly experience sunlight variation as a discontinuous function. The resulting skin pigmentation buffer dysfunction may promote diseases associated with over- or under-exposure to sunlight, the most striking example being melanoma. In addition to promoting discontinuity of sunlight exposure, sun-avoidance campaigns may undermine sun-dependent biologic pathways such as melatonin and vitamin D that appear to protect against cancer. These issues may partly explain the rise in melanoma rates despite the implementation of sun-avoidance campaigns. Also discussed is the potential role that discontinuous temperature variation associated with modern lifestyles plays in diseases such as viral infection, heart failure, and acute coronary syndromes. Acute discontinuous changes in pressure and oxygen levels related to air travel may contribute to autonomic dysfunction, venous thromboembolism, and viral infections. Therapeutic implications are discussed.

Whether primary or metastatic, cardiac neoplastic diseases are relatively uncommon disorders. Although any malignancy may involve the heart, malignant melanoma (MM) has a significant tendency to metastasize to the heart. Cardiac involvement may occur during the course of MM or years after surgical therapy, but rarely metastasis may be the initial manifestation of the disease. This article reports a metastatic MM case that was initially manifested by heart failure symptoms because of right ventricle outflow obstruction and for which the primary focus could not be determined.

Malignant melanoma has a very high tendency to metastasize to the heart. Although most cardiac metastases of melanomas are clinically silent, the lesions may present with life-threatening cardiac morbidities, including dysrhythmia, right ventricular outflow tract obstruction, myocardial dysfunction, pericardial effusion, or heart failure. In selected patients who have a solitary intracardiac melanoma, surgical resection can provide relief from clinical symptoms and minimize potential cardiac sequelae of the tumor. Because tumor embolization of cardiac melanoma has been reported, the presence of atrial metastatic melanoma can be another indication for surgery.Herein, we present the case of a 31-year-old man who had a right atrial metastatic melanoma of unknown primary origin. He underwent surgical resection of the tumor before beginning a course of chemotherapy. After 1 year, he was well and had no symptoms. We describe the clinical features of this rare presentation of melanoma.
