Ifosfamide given to 42 patients iv at 2-2.5 g/m2/day X 4 resulted in partial responses in ten of 28 (36%) evaluable patients with adult soft tissue sarcomas, including two of two with chondrosarcoma; none of nine with pediatric sarcomas (Ewing's sarcoma, osteogenic sarcoma, or rhabdomyosarcoma) achieved partial response. All of the pediatric patients had failed to respond to complicated three- to six-drug regimens of up to 18 months in duration. The response rates in patients with and without prior cyclophosphamide (32%; seven responses among 22 patients; and 20%, three responses among 15 patients) were not significantly different, supporting in vitro evidence of a lack of cross-resistance between the two related compounds. Myelosuppression was dose-limiting. Hemorrhagic cystitis was not observed in patients treated with 400-500 mg of mesna iv every 4 hours during ifosfamide treatment. Nausea and vomiting were generally mild or moderate. Alopecia was universal but reversible. Of the first 11 patients, five became somnolent or developed visual hallucinations (during six of the 12 total courses administered to the five patients). Only one patient had two episodes of neurotoxicity. After reduction of the use of iv antiemetics and major narcotics, single episodes of neurotoxicity were seen in five of the next 27 patients. An asymptomatic acidosis developed in most patients, requiring bicarbonate replacement in one. Ifosfamide appears to be active in previously treated patients with sarcomas and should be evaluated in patients with less extensive prior treatment.

An autopsy case of a huge tumor in the right thorax is reported. A 71-year-old man complained of dyspnea and died after three months of hospitalization. The tumor, consisting of a circumscribed mass measuring 24 X 24 X 8 cm and weight 3.7 kg, originated from the right diaphragm and had no metastasis. Histologically, the tumor comprised multiple mesenchymal elements of fibrosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma, and there was no distinct border between these different components. This tumor fulfills the criterion of malignant mesenchymoma (Stout). The histogenesis of the tumor is discussed with a survey of literature.

Twenty children with recurrent or unresponsive tumours (10 Wilms', 3 rhabdomyosarcoma, 4 Ewings's, 1 osteosarcoma, 1 hepatoblastoma, 1 hepatoma) and one untreated patient with renal carcinoma were given ifosfamide as a 24-h infusion (5 mg/m2), with mesna as uroprotective. The number of courses ranged from 1 to 13 (median 3), and the interval between them was 2-3 weeks. Sixteen of these patients had previously received cyclophosphamide. Complete clinical responses were seen in 3 cases (2 Wilms' and 1 Ewing's) and lasted 5, 7, and 9 months. Partial responses were seen in 3 instances, mixed response or stable disease in 4, and progressive disease in 11. Treatment was well tolerated in most patients, with no cystitis or severe myelosuppression, but 2 children developed transient neurological symptoms and 1 became hypertensive. Nausea and vomiting were controlled by high-dose dexamethasone in most children. Plasma ifosfamide levels were estimated by means of gas-liquid chromatography in 10 patients. Peak concentrations ranged from 38 to 125 micrograms/ml (median 80). The elimination half-life, at 2.5-5.2 h (median 3.2) was shorter than previously reported in adults. Future studies should test the possibility that ifosfamide-containing combination chemotherapy may be more effective than the regimens, usually including cyclophosphamide, that are currently used as front-line treatment of embryonal and Ewing's sarcoma.

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 review summarizes the most recent results obtained with present combined adjuvant strategy for the treatment of resectable cancer. Recent important randomized clinical trials, either unicentric or polycentric, are discussed. As far as pediatric tumors are concerned post-surgical adjuvant chemotherapy was proved to play a useful role in prolonging the disease-free survival in Wilms tumor, rhabdomyosarcoma, Ewing sarcoma. Results obtained in the treatment of medulloblastoma and osteogenic sarcoma need further investigations. In adult neoplasms the most important results with combined modality approach are presently being obtained in breast cancer and probably in melanoma. No consistent improvement by adjuvant chemotherapy has been observed in colorectal cancer.

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.

Primary solid tumors were mechanically and/or enzymatically disassociated, and the resulting suspensions of single cells and small clumps of cells were seeded onto three different substrates, i.e., tissue culture plastic, rat smooth muscle cells (SMCs), and SMC-derived extracellular matrix. Tests of the relative effectiveness of these substrates in supporting the survival and/or growth of ten different neoplasms demonstrated that only two explants remained viable for longer than 2 weeks when seeded onto tissue culture plastic while nine of the ten survived on biological substrates for 1 month or longer. Thus, tissue culture plastic was a poor substrate for primary pediatric neoplasms. In general, more than 80% of the most common solid neoplasms in childhood (brain tumor, neuroblastoma, renal tumor, rhabdomyosarcoma, osteogenic sarcoma, and Ewing's sarcoma) routinely survived or grew in long-term cultures when cultured onto SMCs or their matrix. Both substrates were effective in promoting survival and/or growth; however, cells of neuroblastomas and certain brain tumors showed a preference for a living smooth muscle substrate. Tumor cells maintained their characteristic cellular and subcellular morphology when compared with the histology of the in vivo neoplastic lesions. Light and electron microscopy of selected neoplasms cultured on SMCs for various time periods demonstrated areas of distinct cellular invasion and/or partial destruction of the SMC multilayers which correlated with the invasive potentials of the neoplasms in patients. Invasion and destruction of the SMCs were also noticed with quiescent tumor cell cultures, indicating that growth was not a necessary property of invasion. Several neoplasms were also capable of the degradation of connective tissue proteins as indicated by the hydrolysis of radiolabeled SMC matrices, but simple correlations between the extent of matrix degradation and invasive ability could not be drawn. The culture system described consistently provided for the survival and/or growth of the most common pediatric tumors for long time periods. Thus, basic biological properties of primary tumors, e.g., growth, invasive potentials, and differentiation capabilities, could be investigated routinely.

Three cases of heterologous sarcomas of the uterus are presented. Two were mixed tumors; one was a lipoleiomyosarcoma; and one was an osteogenic sarcoma with leiomyosarcoma. The third was a rhabdomyosarcoma. These tumors are believed to behave more aggressively than mixed mesodermal tumors. Six months after initial diagnosis, the lipolieomyosarcoma had metastasized to a vertebra. Following radiation therapy, the metastases recurred at the same site. The rhabdomyosarcoma of the uterus produced lung metastases 4 months following surgery, and the patient died 14 months after initial diagnosis despite extensive chemotherapy. The patient with osteogenic sarcoma of the uterus with leiomyosarcoma had been treated with Adriamycin and is alive and well 1 year following initial diagnosis. The histogenesis of these tumors is reviewed.
