In a prospective study, 44 children receiving
Adriamycin
(
ADR
) for various neoplastic diseases underwent serial estimations of the systolic time intervals (STI) for the noninvasive assessment of left ventricular myocardial performance. Five of the 44 children developed clinical signs of
ADR
-related congestive heart failure at a cumulative dose of less than 550 mg/m2 body surface area. Clinical symptoms, changes in the electrocardiogram and in the chest X-ray were preceded in every case by changes of the STI, mainly a prolongation of the left ventricular pre-ejection period (PEP), or a decrease of the ejection time (ET)/pre-ejection period (PEP) ratio (ET/PEP). A continous increase of the PEP and a decrease of the ET/PEP-ratio also gave an indication of myocardial dysfunction during
ADR
treatment in the other children without clinical signs of congestive heart failure. This subclinical cardiotoxic effect of
ADR
below the critical cumulative dose of 550 mg/m2 was observed in children with pre-existent myocardial damage, with preceding thoracic irradiation, or during concurrent chemotherapy, of which cyclophosphamide seemed to be most important. Thus, the estimation of the STI proved helpful and reliable in the early detection of incipient
heart failure
and in the selection of high risk patients in children receiving
ADR
treatment.

A 20-year-old man with metastatic Ewing Sarcoma developed severe congestive heart failure. Because he had been treated with a large amount of
Adriamycin
, the diagnosis was initially thought to be
Adriamycin
cardiotoxicity. However, ante- and post-mortem studies revealed the presence of massive cardiac metastases. At post-mortem, there was no evidence of
Adriamycin
cardiotoxicity. This case emphasizes that cardiac metastases must be considered in the differential diagnosis of
heart failure
in patients treated with
Adriamycin
.

Between December 1982 and November 1990, 31 patients with advanced urothelial carcinoma were treated with one of two combination chemotherapy regimens. A total of 20 patients were treated with 3 mg/m2 mitomycin C and 300 mg/m2 cyclophosphamide given intravenously every 10-14 days and with 180 mg/m2 5-fluorouracil (5-FU) given intravenously every day for as long as possible (CF-Mito regimen). After the patient had been discharged from the hospital, the same treatment with CF-Mito was performed except that 180 mg/m2 5-FU was replaced by 400 mg/m2 UFT (a mixture of tegafur and uracil) given orally. A total of 11 patients whose tumor had relapsed during the first-line treatment were given 60 mg/m2 cisplatin, 40 mg/m2
Adriamycin
, and 40 mg/m2 methotrexate intravenously every 28 days (PAM regimen). In all, 20 patients received 4-44 (mean, 9.7) courses of CF-Mito over a period of 1.5-24 (mean, 5.3) months. The results obtained in these 20 patients with evaluable lesions included no complete remission (CR), 4 partial remissions (PRs), 9 cases of stable disease (SD), and 7 cases of progressive disease (PD). The PR duration was 1.5-22 (mean, 7.5) months. The side effects encountered in this group included anorexia, nausea, vomiting, myelosuppression, diarrhea, stomatitis, liver damage, and
heart failure
. In all, 11 patients received 3-7 (mean, 4.1) courses of PAM over a period of 3-14.5 (mean, 5.2) months. All 11 patients had evaluable lesions, and their responses included no CR, 5 PRs, 3 cases of SD, and 3 cases of PD. The PR duration was 1-3 (mean, 1.6) months. The side effects encountered in this group included anorexia, nausea, vomiting, myelosuppression,
heart failure
, and hair loss.

Experimental evaluation of new therapy for congestive heart failure has been hampered by the lack of a simple and reliable animal model of
heart failure
. This study was undertaken to develop a canine model of chronic left ventricular dysfunction. A left thoracotomy was performed in 9 adult mongrel dogs. A 1.5-mm Silastic (Dow Corning) catheter with an attached subcutaneous access port was positioned in the left main coronary artery. Six animals received five weekly infusions of
Adriamycin
(doxorubicin hydrochloride) (10 mg/wk), and 3 received saline solution. Hemodynamic studies were performed before insertion of the catheter and 2 weeks after completion of the infusions. In animals that received
Adriamycin
, rest ejection fraction declined from 0.54 +/- 0.03 to 0.35 +/- 0.03, cardiac output fell from 5.6 +/- 0.6 to 3.9 +/- 0.5 L/min, and left ventricular end-diastolic volume increased from 76 +/- 9 to 99 +/- 12 mL (p less than 0.05). There was a small increase in right atrial pressure (2.7 +/- 1 versus 5.7 +/- 1 mm Hg) but no change in right ventricular ejection fraction (0.31 +/- 0.04 versus 0.30 +/- 0.03). In no animal did alopecia, weight loss, neutropenia, or anemia develop. Histological changes consistent with
Adriamycin
-induced cardiac toxicity were found in each dog. No significant hemodynamic or histological changes occurred in the control animals. Administration of
Adriamycin
into the left main coronary artery causes left ventricular dysfunction without resulting in systemic side effects or compromising right ventricular function. This animal model could be used to evaluate the effects of new possible therapy, such as cardiomyoplasty, on left ventricular failure.

The functional integrity of the beta-adrenergic stimulatory pathway in a rabbit model of
heart failure
induced by long-term adriamycin treatment was investigated.
Adriamycin
-induced cardiomyopathy was produced in 46 rabbits by injecting 0.75 mg/kg of adriamycin, three times per week, for a period of 11 weeks. Biochemical studies performed on isolated membrane preparations revealed a 40 and 55% decrease in basal adenylyl cyclase activity in the left and right ventricles of the adriamycin treated rabbits, respectively. Furthermore, the Vmax of forskolin stimulation was significantly lower in both ventricles with no change in Kact. The Vmax of 5'-guanylylimidodiphosphate stimulation of the stimulatory guanylyl nucleotide binding protein Gs and beta-adrenergic receptor stimulation by isoproterenol were also significantly decreased (42%) in both ventricles of the adriamycin-treated rabbits with no change in Kact. Despite the decrease in receptor-mediated cyclic AMP production, no decrease in beta-adrenergic receptor population was found. Mechanical studies on the isolated right ventricular papillary muscle revealed a decrease in baseline total tension (3.1 +/- 0.4 g/mm2 to 1.8 +/- 0.2 g/mm2) and dT/dt (15.1 +/- 1.6 g/mm2 s to 7.9 +/- 0.8 g/mm2 s) in the adriamycin-treated rabbits. Furthermore, tension generation and dT/dt response to increasing concentrations of forskolin or isoproterenol were both significantly lower in the adriamycin-treated rabbits as compared to normal. We suggest that a decrease in the activity of the adenylyl cyclase component of the beta-adrenergic stimulatory pathway is largely responsible for the decrease in cyclic AMP generation in the adriamycin-treated rabbits. This defect may play an important role in the decrease of contractility in this model of
heart failure
.

Preoperative intraarterial (IA) cisplatin (CDP) was administered to 92 patients with nonmetastatic osteosarcoma. The ages of the patients ranged from 4 to 28 years. Sixty-four patients (70%) received 2 or 3 preoperative courses and 28 (30%) received 4 or more. Sixty-two specimens were available for pathologic examination to assess the degree of tumor necrosis. More than 90% tumor destruction was observed in 16 of 42 patients (38%) who received 1 to 3 preoperative courses as opposed to 17 of 20 (85%) who received 4 or more courses. Patients who received 4 or more courses had a 2-fold probability of achieving more than 90% tumor necrosis, and 68% underwent conservative surgery. Of those who received 3 or less courses, 23% underwent conservative surgery. Postoperatively, patients were treated with intravenous (IV) CDP alternating with doxorubicin (ADR) (
Adriamycin
, Adria Laboratories, Columbus, OH). Pulmonary metastases developed in 36 patients, bone metastases in 2, and local recurrence in 6. Two patients died of
cardiac failure
without evidence of disease. Thus, 46 patients (50%) were continuously free of disease 18 to 78 months after diagnosis. Univariate and multivariate analyses showed that male sex, low grade preoperative chemotherapy-induced necrosis, and nonosteoblastic histologic condition were prognostic factors predictive of recurrence, while male sex and large tumor size were prognostic factors predictive of death. These results are comparable with those reported by other centers and are superior to our previous experiences that yielded survival rates of 5% to 10%. A substantial number of patients also had the opportunity to achieve tumor removal with conservative surgery.

Five patients with high risk multiple myeloma not responsive to standard chemotherapy were treated by high-dose chemotherapy (Melphalan, Cyclophosphamide) (HDC) and total body irradiation (TBI) followed by autografting with blood stem cells. These cells were previously collected by leukaphereses from eight to twelve occasions during hematopoietic recovery following profound aplasia induced by each course of intensive chemotherapy (Vincristine,
Adriamycin
, Cyclosphosphamide, Prednisone) when the patient reached a neutrophil count of 1,000/microliters and a platelet count of 100,000/microliters. No patients had evidence of tumor plasmacells in leukaphereses products using cytology, immunocytochemistry and immunofluorescence. At this time the patient 5 is not evaluable because of the short follow-up. One died at day 30 from
heart failure
. All living patients achieved a complete remission which persisted at a follow-up of 300, 261 and 136 days. Autologous blood derived hematopoietic stem cells induced successful and sustained engraftment in all living patients. Our results indicate the feasibility of this therapeutic approach over allogenic or autologous bone marrow transplantation in selected patients with high tumour mass multiple myeloma.

Three hundred fifteen patients with operable gastric cancer were randomized to receive fluorouracil,
Adriamycin
(doxorubicin; Adria Laboratories, Columbus, OH), and mitomycin (FAM) or no adjuvant treatment between September 1981 and July 1984. After excluding ineligible patients, 281 patients are included in this analysis. Treatment was moderately well tolerated by the majority of patients, the common side effects being nausea and vomiting (58%) and alopecia (57%). Three possible treatment-related deaths were seen, all due to
cardiac failure
. At median follow-up of 68 months, 164 patients have died, 73 in the treated arm and 91 in the control arm. There was no significant difference in disease-free or overall survival between the two arms of the study (P = 0.21). There is some evidence that patients with more advanced carcinoma (T3-T4) derived some benefit from treatment (P = 0.04). The interpretation of this finding must take into account that all subgroups were defined retrospectively, and this could, therefore, be a chance finding. We conclude that adjuvant chemotherapy as given in this trial is not indicated as routine treatment in operable gastric cancer, but that further evaluation in stage T3-T4 patients is warranted.

To detect
Adriamycin
cardiomyopathy, radionuclide myocardial imagings with Tl-201, Tc-99m pyrophosphate, I-123 metaiodobenzylguanidine and Ga-67 were performed in a 49 year-old-woman receiving
Adriamycin
(a total dose of 230 mg/m2) for the treatment of breast cancer. This patient demonstrated symptoms of congestive heart failure 2 months after the last intravenous administration. At the period of performing the radionuclide studies, echocardiographic LV ejection fraction (EF) was 22%. Despite severe deterioration of cardiac function, Tl-201 SPECT demonstrated no defect and Tc-99m pyrophosphate (PYP) SPECT demonstrated no positive finding. I-123 metaiodobenzylguanidine (MIBG) scintigraphy demonstrated no regional defect. However, I-123 MIBG washout rate during 4 hours was markedly enhanced, probably reflecting abnormalities of norepinephrine kinetics due to the progression of
heart failure
. Compared to these pharmaceuticals, Ga-67 was diffusely accumulated in the heart. Then, 5 months after the first study, when LV EF improved to 30% and congestive symptoms disappeared probably owing to beta-blockade therapy, myocardial accumulation of Ga-67 markedly reduced. It has been reported that Ga-67 accumulates in malignant tumor cells and leukocytes. Since, in
Adriamycin
cardiomyopathy, myocardial accumulation of leukocytes with myocardial fibrotic changes have been histologically demonstrated, the results of Ga-67 scintigraphy may reflect the accumulation of leukocytes. Thus, this case indicates that Ga-67 scintigraphy is advantageous for detecting
Adriamycin
cardiomyopathy and may be more useful than Tl-201 and Tc-99m PYP scintigraphies.

The hemodynamic and hormonal changes produced by adriamycin-induced cardiomyopathic congestive heart failure in rabbits were studied.
Adriamycin
cardiomyopathy in rabbits led to ventricular dilatation, pleural and pericardial effusions, hepatic congestion, and ascites. These pathological changes were associated with the maintenance of a normal blood pressure but a lowered cardiac output and increased total peripheral resistance. Plasma renin activity and plasma norepinephrine were increased twofold in rabbits with congestive cardiac failure. However, plasma vasopressin and osmolality were normal, whereas an increased vascular sensitivity to the infusion of exogenous vasopressin was demonstrated. Despite the normal levels of plasma vasopressin, administration of a specific vascular vasopressin antagonist led to a fall in blood pressure, a significant increase in cardiac output, and a decrease in total peripheral resistance. No such hemodynamic changes occurred on infusing normal rabbits with the vascular vasopressin antagonist, nor did any significant hemodynamic changes occur on injecting vehicle in rabbits with
heart failure
. These results suggest that in adriamycin-induced cardiomyopathic
heart failure
in rabbits, there is activation of the renin-angiotensin system and the sympathetic nervous system together with an increased sensitivity to vasopressin. These three hormonal systems help to maintain blood pressure by increasing total peripheral resistance in this experimental model of
heart failure
.
