Morphological studies on sarcomas induced in syrian hamsters by cellfree transmission are described. The tumour tissue for the cellfree preparations stemmed from a sarcoma, containing C-particles. Basically, three histological groups have been distinguished: 1. neoplasms of the peripheral nerve-sheath, 2. undifferentiated sarcomas, and 3. liposarcomas. Furthermore, a
rhabdomyosarcoma
, an
angiosarcoma
and, in a heterotransfection on rat, an osteosarcoma have been established. The great majority of tumours could be transmitted by cellfree preparations. To this neoplasms belong the undifferentiated histological structure.

The present study consists of 651 cases of soft tissue tumors originating in the head and neck area. Among these tumors 628 were benign (96%), while there were only 23 malignant cases (4%). In the benign group hemangiomas showed the highest incidence (47%) followed by tumors of adipose tissue (19%) and those of peripheral nerves (12%). Rare tumors consisted of nodular fascitis, hibernoma, lipoblastomatosis, glomus tumor, granular cell tumor, and chondroma. The majority of cases in the malignant group were either those of muscle origin or blood vessel origin. Excepting for two cases of
rhabdomyosarcoma
of the embryonal type and two cases of
angiosarcoma
, all showed recurrence and/or metastasis and terminated in death. Three cases of liposarcoma of either well-differentiated or myxoid type had a good prognosis with all three living for 3 or more years without any recurrence. Other malignant tumors consisted of malignant schwannoma, fibrosarcoma, malignant fibrous histiocytoma, alveolar soft part sarcoma, and chordoma. The age, sex, anatomical location, and differential diagnosis have also been described.

Undiluted, fivefold-diluted, and 25-fold-diluted doses of a stock of Moloney murine sarcoma virus were injected directly, in a volume of 0.025 ml, into the backs of fetal Sprague-Dawley rats by laparotomy through the uterine wall at 18 days of gestation. During the first 8 weeks after birth the young responded to the virus with remarkably high but dose-dependent incidences of neoplasms. When a one-fifth dilution of the virus preparation was inoculated at fetal ages 16, 18, and 20 days, the incidences of lesions decreased with advancing fetal age. The tumors developed preferentially at the virus inoculation site and/or in the proximal parts of the extremeties; all were considered to be of mesenchymal derivation, i.e., malignant mesenchymoma,
rhabdomyosarcoma
, osteosarcoma, fibrosarcoma or fibromyxosarcoma,
hemangiosarcoma
, plasmacytoma, and a giant cell tumor. This injection procedure provided us with a valuable experimental tool for the rapid screening or testing of potential chemical carcinogens and other biologic studies.

Primary giant-cell carcinoma of the lung is an infrequent observation. It is distinguished clinically solely its fairly rapid development but otherwise it does not seem to have any predilection for localization, age or sex. Histologically, differential diagnosis with othe tumours such as
angiosarcoma
,
rhabdomyosarcoma
, chorioepithelioma and others is of interest. Three cases of primary giant-cell carcinoma of the lung are reported and the various clinical and anatomopathological aspects discussed.

During the 5-year period between 1988 and 1989, five patients with primary sarcomas of the liver underwent surgery. Since the patients presented in an early stage of the tumor, all the sarcomas were resectable, in three cases with wide margins (R-0 resection). Five histological types were detected: malignant hemangiopericytoma, malignant fibrous histiocytoma,
hemangiosarcoma
,
rhabdomyosarcoma
, and embryonal sarcoma. Two patients with high-grade sarcomas received adjuvant chemotherapy. The follow-up was favorable in three patients with R-0 resections (two had adjuvant chemotherapy). They were still alive, with no evidence of disease 30, 46, and 63 months after the diagnosis. The two other patients had to be reoperated on for local recurrences. Both died of their tumor disease, 30 and 35 months after the initial diagnosis. Extensive chemotherapy in one of these cases failed to arrest tumor progression. Hence, liver resection with wide margins is a very important measure in such cases.

Tumours of mixed glial and sarcomatous elements occurring in intracranial neoplasms are well recognised and have been termed gliosarcomas. These tumours account for up to 8% of all glioblastomas. The sarcomatous elements are thought to derive from the neoplastic transformation of mesenchymal cells in or adjacent to the tumour. This transformation usually has the appearance of a fibrosarcoma or
angiosarcoma
. Alternative mesenchymal neoplastic differentiation may occur, however, giving rise to the appearances of chondrosarcoma and osteosarcoma. In 1969 Goldman described a case in which the sarcomatous elements of a mixed gliosarcoma appeared, on the basis of light microscopy alone, to differentiate towards skeletal muscle having the features of a
rhabdomyosarcoma
. He coined the term gliomyosarcoma. In 1986 Barnard et al reported a second case and demonstrated the features of
rhabdomyosarcoma
using the electron microscope. A further case characterised with both light microscopic and immunohistochemical techniques is reported.

From July 1982 to December 1989, 43 of 1,583 adults (2.7%) with soft tissue sarcoma admitted to the Memorial Sloan-Kettering Cancer Center (MSKCC) had tumors arising from the urinary tract and male genital tract (urological sarcoma). The most common site of origin of the tumor was paratesticular (14 patients), followed by the prostate/seminal vesicle (12), bladder (10) and kidney (7). The most common histological type was leiomyosarcoma (19 patients), followed by
rhabdomyosarcoma
(14), liposarcoma (5) and 5 other histological sarcoma categories (
angiosarcoma
, malignant fibrous histiocytoma, mesenchymoma and 2 undifferentiated sarcomas). Most of the tumors were high grade (86%) and more than half (56%) were greater than 5 cm. in diameter. A total of 9 patients (21%) presented with metastatic disease, 8 of whom had
rhabdomyosarcoma
. Complete resection with negative microscopic margins was possible in 58% of the patients. Actuarial relapse-free survival for all patients at 3 and 5 years was 55% and 40%, respectively. There were no significant differences in survival based on patient age, sex or histological tumor type. Favorable prognostic variables by univariate analysis included tumor diameter less than 5 cm., low histological grade, paratesticular or bladder tumor site and complete surgical resection. Application of the MSKCC sarcoma staging system, which is based on grade, size, depth and presence or absence of metastasis, was useful to predict survival. In our experience patients with stage 3 (high grade, greater than 5 cm., 15 patients) or stage 4 (metastatic disease, 9 patients) had a combined 3-year relapse-free survival rate of only 26% and they should be considered candidates for adjuvant treatment protocols.

There were 79 cases of cardiac tumors seen from 1957 to July 1988. 49 (62.0%) of them were benign and 30 (38.0%) malignant. All the 49 benign tumors except 2 were surgically excised and found to be myxoma. Of them, 18 patients were male and 31 female. 85.7% of the tumors were located in the left atrium, 12.2% in the right atrium and 2.0% in the left ventricle. Palpitation, dyspnea, chest oppression, fever, episodes of syncope and hemiplegia, cough, diastolic and systolic murmurs at the apical or tricuspid area were the common symptoms and signs. Atrial fibrillation was found only in 2 cases. Echocardiographic findings were diagnostic while ECG and X-ray findings were nonspecific. Four patients died after operation. Of the 30 cases of malignant tumors, 15 were secondary tumors metastasized mainly from the lung or mediastinal malignancies. Of 11 primary tumor cases (7 males and 4 females), 3 were malignant lymphoma, 2 mesothelioma of pericardium, 2 malignant myxoma, 1
angiosarcoma
, 1 leiomyosarcoma, 1 fibrosarcoma and 1
rhabdomyosarcoma
. Another 4 cases were not studied histopathologically. The clinical manifestations, ECG and X-ray findings of the 11 primary tumors were nonspecific but echocardiography was helpful to the diagnosis. Six patients were operated on and 1 died during hospitalization.

A Head and Neck Sarcoma Registry was established by the Society of Head and Neck Surgeons to review treatment results of a rare tumor by surgeons with special interest in this anatomic site. Two hundred fourteen patients were analyzed. There were 194 adult tumors and 20 pediatric tumors. The major sites included parotid and neck, 20%; face and forehead, 18%; maxilla and palate, 13%; scalp, 12%; mandible, 11%; paranasal sinuses, 7%; larynx, 2%; and oral cavity, 5%. Eighty-four percent were resectable. The disease-free survival was 56%; overall survival was 70% at 5 years. Major determinants of survival were adequacy of resection (margins free of tumor) and tumor type. Survival differed according to tumor cell type (tumor grade was not available). Patients with chondrosarcoma and dermatofibrosarcoma had survival approaching 100%. Patients with malignant fibrous histiocytoma (MFH) and fibrosarcoma (FSA) had intermediate survival of 60% to 70%. The worst survival, less than 50% at 5 years, occurred in patients with osteosarcoma,
angiosarcoma
, and
rhabdomyosarcoma
in decreasing order. This suggests a rationale for identifying high-risk patients for prospective adjuvant protocols. This study emphasizes the value of recording uncommon tumors to provide relevant information for future study and possibly therapy.

Fifteen patients with biopsy-proven mediastinal germ cell tumors treated with platinum-based chemotherapy were reviewed. They had a period of 4 to 6 weeks between the onset of symptoms and diagnosis. Four patients had sarcomatous elements in their tumor in association with common germ cell histologies. The sarcomatous components consisted of one
angiosarcoma
, one
rhabdomyosarcoma
, and two cases with mixed
angiosarcoma
and
rhabdomyosarcoma
. All patients with sarcomatous elements died; the median survival for these patients was 9 months. In contrast, six (54%) of the patients who did not have sarcomatous elements in their tumor are long-term disease-free survivors 5 to 8 years after diagnosis. The occurrence of sarcomatous elements in a mediastinal germ cell tumor is a poor prognostic sign, and therapy should be oriented to include drugs and regimens that may be effective against sarcoma.
