We will report the result obtained from sensitivity tests on various anti-cancer agents for malignant bone and soft-tissue tumors based on SDI (Succinic Dehydrogenase Inhibition Test) method with the use of enzymic activities as marker since 1976. Our study comprised 27 cases altogether 15 cases of osteosarcoma, one case each of Ewing's sarcoma, malignant fibrous histiocytoma and malignant lymphoma, 3 cases of metastatic bone tumor and one case each of angiosarcoma, fibrosarcoma, rhabdomyosarcoma, liposarcoma, 2 cases of metastatic lung tumor among soft-tissue sarcomas. In all cases, sensitivity tests were done on the tumor tissues according to SDI method at the same time as biopsy for the determination of the appropriate medications. Four to six weeks of pre-operative intra-arterial infusion was done followed by radical operation. The results obtained are as follows. Observing the long-term results between subjects that applied anti-cancer agents decided by sensitivity test and those without sensitivity test. The 5 years cumulative survival rate jumped from 30.5% to 50.5%, showing a clear improvement.

Since 1970, we have carried out cancer chemotherapy and immunotherapy in cooperation with Japanese scientists, particularly Prof. H. Umezawa, who has generously supplied bleomycin, peplomycin, acalcinomycin A (ACM), THP-adriamycin (THP), neothramycin and bestatin. Malignant tumors curable by pharmacotherapy are polycythemia vera (CR 100%), acute lymphoid leukemia (ALL) (CR 80%), Burkitt tumor (CR 80 or 50%), Hodgkin disease (CR 80%), chorioepithelioma (CR 80%), testicular cancer (CR 80%), ovary cancer of children (CR 80%), Wilms renal cancer (CR 60%), rhabdomyosarcoma (CR 75%), osteosarcoma (CR 60%), Ewing tumor (CR 60%), brain tumor of children (CR greater than 50%), testicular embryonal cancer of children (CR greater than 50%), acute myeloid leukemia (AML) (CR 50%), non-Hodgkin lymphoma (NHL) (CR 50%), ovary cancer of adults (CR 40%), small cell lung cancer (CR 20%) and breast cancer. Our experimental and/or clinical experience with ACM, THP, methoxy-9-ellipticine lactate, navelbine, 4-demethyl-epipodophyllotoxin-beta-d-ethyledene glucoside, bestatin and interferon is presented. ACM is effective against AML, ALL, NHL, Burkitt tumor, breast cancer. We have comparatively investigated cardiac and dermal toxicity of 12 kinds of anthracycline antibiotics and mitoxantrone, using golden hamsters. Of the drugs examined, ACM, THP, AD-32 and AD-143 cause much less cardiomyopathy and alopecia than the other agents. The results have been confirmed by electron microscopic studies. Bestatin is an immunorestorator, which recovers immunological functions decreased in aged animals. We hope that cancer chemotherapy and immunotherapy will progress in future and contribute to cure of neoplasms. Japanese scientists have been making a great contribution in the field of cancer pharmacotherapy, and we are eager to cooperate with Japanese scientists in cancer treatment studies.

In a study of 21 malignant Mullerian mixed tumors of the uterus seen at The New York Hospital from 1957 to 1977, we found an unexpectedly high incidence (67%) of heterologous tumors which we attribute to an assiduous search for striated cells. Four patients, all of whom had had heterologous tumors, were free of tumor 3 1/2 to 17 years after diagnosis. The tumors were confined to the corpus and exhibited no more than moderate myometrial invasion. The heterologous element was rhabdomyosarcoma in three cases and osteosarcoma in one. Fifteen cases were treated in the last decade as compared with six in the previous decade.

The histological diagnosis of malignant fibrous histiocytoma (MFH) seems to have become recently fashionable among pathologists, although its histogenesis and diagnostic criteria are not entirely settled as yet. For practical purposes the differential diagnosis with other easily mistakable mesenchymal tumors should be strictly made with great caution, because of variable histological features of this tumor. The authors attempted to elucidate the differential points from other tumors in a review of 189 cases of malignant soft tissue tumors. Some cases of carcinoma mimicking MFH were also reviewed. No single criterion for making the histological diagnosis of MFH was obtained. Its histological features and differential points from pleomorphic rhabdomyosarcoma and fibrosarcoma were tabulated. The recognition of a true tumor osteoid was emphasized as a single differential point between osteosarcoma and MFH often with fibrous areas mimicking osteoid. Renal cell carcinoma metastasizing to bone, which was misinterpreted as MFH on biopsy tissue, was also described and its differential point was stated.

beta-Adrenergic receptors were demonstrated in membrane preparations from 6 human Ewing's sarcomas and compared to those from 46 other pediatric cancers with the use of the beta-adrenergic antagonist (-)-(3H)dihydroalprenolol [(-)[3H]DHA]. In contrast to the high numbers of receptor sites found in Ewing's sarcomas (55-640 fmol x mg-1 protein; dissociation constant Kd, 1-2 nM), other childhood cancers (neuroblastoma, rhabdomyosarcoma, brain tumors, lymphoma, osteosarcoma, hepatoblastoma, yolk sac, and Wilms' tumor) contained in general fewer beta-adrenergic receptor sites. Characteristics of (-)-[3H]DHA binding were therefore more fully characterized in the Ewing's tumors. Competition of (-)-[3H]DHA binding by classical catecholamine agonists, as well as by subtype selective agents metoprolol and zinterol, demonstrated the presence of a homogeneous population of beta 1-adrenergic sites in several Ewing's tumors. Adenylate cyclase activity in all Ewing's sarcomas was enhanced by GTP and NaF. However, in spite of high numbers of beta-adrenergic receptors, (-)-isoproterenol was not very effective in the activation of adenylate cyclase activity in several of the Ewing's tumors tested. Neither guanyl-5'-yl-imidophosphate nor GTP altered agonist potency for the receptor site in these catecholamine-insensitive tumors. Hill coefficients obtained from the competition experiments with (-)-isoproterenol (in the presence or absence of guanine nucleotide) were approximately 1.0. These uncoupled receptors were resistant to N-ethylmaleimide denaturation and were densensitized only 50% during culture in the presence of (-)-isoproterenol. Thus Ewing's sarcomas are relatively rich in beta-adrenergic sites, and several tumors appear to have a coupling lesion involving guanine nucleotide-dependent regulatory protein interaction with beta-adrenergic receptors and adenylate cyclase, similar in phenotype to that described in the (unc) variant of S49 mouse lymphoma.

Sections from 21 tumours diagnosed as primary or metastatic rhabdomyosarcoma were stained for alpha and beta enolase. The cases were subdivided into embryonal and alveolar subtypes (38% and 62%, respectively). Positive cytoplasmic staining for alpha enolase was seen in all but one case, and cytoplasmic staining for beta enolase was seen in some cells in 18 of the 21 cases (86% of the total, 88% of the alveolar subgroup, and 85% of the embryonal subgroup). No cells stained positively for beta enolase in the control series of neuroblastomas, fibrosarcomas, Wilms' sarcomas, and an osteosarcoma. The results show that beta enolase is a sensitive marker of muscular differentiation in rhabdomyosarcoma.

We studied the effect of total parenteral nutrition on recovery from myelosuppression in patients receiving intensive chemotherapy. Twenty-seven patients (ages 11 to 33 years) with locally recurrent or metastatic Ewing's sarcoma, rhabdomyosarcoma, or osteosarcoma were randomly selected to receive either conventional oral nutrition or total parenteral nutrition concurrently with intensive chemotherapy. The control group (15 patients) received significantly fewer calories (range 380 to 880/m2 per day, median 685 versus range 1,020 to 2,100 median 1,650) and less nitrogen (0-3.7 g/m2 per day, median 1.5 versus range 5.3 to 12.4, median 8.9) than the group receiving total parenteral nutrition (12 patients). Assessment of recovery from myelosuppression was based on the length of time the absolute granulocyte count was below 500/mm3, the length of time the platelet count was below 40,000/mm3, the number of days the platelet count was below 20,000/mm3, and the number of blood transfusions required. There was no statistical difference in any of the parameters evaluated between the group that received total parenteral nutrition and the control group (p less than 0.05); granulocyte and platelet recovery and the difference in transfusion requirements favored the control group with marginal statistical significance (p = 0.05). The frequency of clinical infections was similar in the patients receiving total parenteral nutrition (five of 12) and in those receiving conventional oral nutrition (five of 15). Thus, although total parenteral nutrition could be safely administered in this severely myelosuppressed population, no benefit could be defined in recovery from bone marrow suppression or frequency of clinical infections.

Malignant peripheral nerve sheath tumors are uncommon sarcomas of Schwann cell or fibroblastic derivation which occasionally show histologic evidence of focal divergent differentiation to rhabdomyosarcoma, osteosarcoma, chondrosarcoma, angiosarcoma, epithelial elements, or a combination thereof. The finding of these heterotopic elements in nerve sheath sarcomas is believed to illustrate the differentiating capacity of neuroectodermal tissue. The authors present the clinicopathologic features of 17 such tumors, which represent 14.7% of the malignant peripheral nerve sheath tumors in the authors' institutional experience. Most of the lesions were associated with von Recklinghausen's disease. These tumors do not seem to differ from ordinary malignant peripheral nerve sheath tumors in presentation, operative, gross, and microscopic features, response to therapy, or prognosis.

During the past 2 years percutaneous fine-needle aspiration biopsy has been employed to help establish or confirm diagnosis in 32 infants and children. A 22-gauge needle is used to aspirate the site of suspected disease. For lesions inside the chest or abdomen, the needle is guided with the help of fluoroscopy, ultrasound, or computed tomography (CT) scan. Nineteen of the 32 patients had malignant disease, including lymphoma, neuroblastoma, rhabdomyosarcoma, Ewing's sarcoma, osteosarcoma, and leukemia. In all patients with solid tumors, tissue obtained at operation confirmed the accuracy of the diagnosis. In seven children with suspiciously enlarged lymph nodes, an open biopsy was avoided when the needle aspirate was clearly benign. In four children, the early appearance of metastatic or recurrent malignancy was confirmed without the need for open biopsy. In this small series, there were no false-negative or false-positive needle aspirates, and no complications directly related to the procedure. The skill and experience of the cytopathologist is essential to the success of this technique. Percutaneous fine-needle aspiration biopsy is a safe and reliable alternative method of establishing a diagnosis in infants and children with suspected malignant disease.

The effects of adriamycin and daunomycin on cardiac function were studied in 33 patients with acute leukemia (16 cases), neuroblastoma (5 cases), osteosarcoma (4 cases), malignant lymphoma (3 cases), rhabdomyosarcoma (3 cases) and malignant histiocytosis (2 cases). The left ventricular function was evaluated by serial echocardiographic assessment. Ejection fraction (E.F.) and shortening fraction (S.F.) of left ventricule were calculated from echocardiographic measurements. Seven of 33 cases (21.2%) revealed the decrease of E.F. and S.F. There was the significant correlation between total doses of daunomycin and E.F. Three patients died of severe congestive heart failure probably due to daunomycin administration. Usually, cardiac dysfunction caused by these drugs has improved within 3 months after the discontinuation.
