Malignancy should always be suspected for any soft tissue tumor. Thus, histologic examination of the totally excised growth is mandatory. Amputation is indicated as a curative measure for recurrencies and lesions that cannot be excised locally. It is also indicated for palliation in cases with ulceration, impaired function, and distant metastases. Adjuvant radio- and chemotherapy, based on the type of tumor, is outlined. The importance of cooperation between surgeon, pathologist, radiologist, and chemotherapist and of a central soft tissue tumor register is emphasized.

The syngeneic cytotoxic T-cell response against a metastasizing murine lymphoma variant was investigated and compared with the response against the non-metastasizing parental tumor line Eb. Anti-tumor cytotoxicity was not detectable in a 4-h 51Cr release assay in spleens taken directly from tumor-bearing animals (primary CMC). After restimulation in vitro (secondary CMC) however, high anti-tumor cytotoxic activity was detected. This activity was mediated by immune T lymphocytes as shown by its sensitivity to treatment with anti-Thy 1.2 serum and complement. Ten cells of the metastasizing tumor ESb, inoculated subcutaneously, were sufficient to raise a local tumor and metastases and to induce cytotoxic T memory cells in the spleens. In contrast, about 104 cells were required to raise a local tumor and to induce splenic cytotoxic T memory cells, when the parental tumor Eb was tested. The specificity studies of the anti-tumor cytotoxic activity demonstrated that cytotoxic T cells could distinguish unrelated, chemically induced syngeneic tumors and also recognize antigenic differences between the parental tumor Eb and its variant ESb. Eb and ESb tumor cells were recognized as carrying distinct antigens at the responder cell level, the stimulator cell level and the target cell level. The in vivo significance of these findings is discussed.

Seven autopsy cases of intramedullary metastases, four in the cervical spinal cord, are reported and the literature reviewed. Whereas lung and breast cancer, malignant melanomas and lymphomas are reported as the most common primary tumors, the present series included three cases of breast carcinoma and two cases each of colon and oat cell carcinoma of the lung. Neither the clinical symptoms nor the neurological signs distinguished intramedullary metastases from the more common extradural deposits, but radiological evidence of vertebral metastases and myelographic stop were present in only one case each, and CSF cytology was negative. Intramedullary deposits in this series were neither associated with extradural tumor nor with spread into the subarachnoid space, while cerebral metastases were present in four cases. This favors hematogenous dissemination rather than direct transdural or perineural spread of these lesions.

Tests were made to determine whether cell surface tumor antigens of metastases differed from the tumor antigens of the cell population of the local tumor growth. C57BL/6 mouse spleen lymphocytes sensitized against monolayers of the local growth of the 3LL Lewis lung carcinoma (L-3LL) in the presence of syngeneic serum generated lymphocytes that were cytotoxic to L-3LL but significantly less cytotoxic to target cells derived from lung metastases (M-3LL). Lymphocytes sensitized against M-3LL were significantly more cytotoxic against M-3LL than against L-3LL cells. Anti-M-3LL cytotoxic lymphocytes but not anti-L-3LL, admixed with either L-3LL cells or M-3LL tumor cells, when injected into syngeneic recipients reduced lung metastasis significantly. Results indicated that cells with high metastatic capacity and distinct antigenic properties exist within the tumor cell population and that immunoselection might be involved in the production of lung metastases.

A report is given of 72 patients suffering from carcinoma of the extrahepatic biliary ducts. Carcinoma of the gallbladder usually grow fast invading the surrounding tissue. Thus cholecystectomy can be performed only as a pallouative procedure in most cases, and partial resection of the liver does not yield better results in general. Carcinoma of the ductus hepaticus usually grows slowly and metastases are formed lately in the course; thus patients usually die due to occlusion of the ducts and jaundice rather than due to the malignancy as such. In these cases good drainage of the bile is essential, in an early stage this can be achieved by placing a tube across the tumor, in later stages an intrahepatic cholangiojejunostomy is to be performed. The technique of this procedure and results obtained in 10 cases are reported.

The new radioimmunoassays for AFP and beta-HCG are highly specific for nonseminomatous, germ-cell testicular tumor in genitourinary patients who do not have liver disease or other cancers. When used together, they are an accurate and sensitive indicator of metastases and are helpful in determining the effectiveness of therapy. However, they are not very useful in the differential diagnosis of scrotal masses.

An autopsy case of a rare primary tumor in a 76-year-old man is described. The tumor is histologically comprised of rhabdomyoblasts massively infiltrating without any epithelial elements referable to be as hepatoma. There was no evidence that regarded the hepatic tumor as metastatic secondary tumor in histological examination of other organs. Furthermore, interesting was the production of alpha-fetoprotein from the tumor cells that was detected by immunofluorescent antibody technique. Review of the literature on primary liver rhabdomyosarcomas or adult hepatoblastomas shows no similar case.

Since prolactin has several modes of action on prostatic growth and physiology, the effect of the antiprolactin bromocriptine on plasma kinetics and intraprostatic metabolism of testosterone was studied in patients with untreated prostatic cancer; a therapy protocol was deduced which was controlled in 27 patients with advanced inoperable prostatic adenocarcinoma. Bromocriptine resulted in a significant suppression of prolactin and testosterone as well and favored testosterone elimination from the plasma pool. Prostatic androgen uptake was enhanced and the intraprostatic metabolism altered in relation to tumor grade. Adjunctive administration of bromocriptine to 27 patients, mostly in the state of hormone resistance, resulted in an overall objective regression of 22.2% and in stable disease in 55.6% of the patients. In half of the individuals a prompt relief of bone pain from osseous metastases was observed as well as improvement of micturition and decline of phosphatase activity. This preliminary data justify further investigations under controlled and randomized conditions.

The short range tissue destruction of beta-emitting radioisotopes can be utilized in painful metastatic disease of the skeleton by employing a radionuclide that is specifically metabolized in or adjacent to these lesions. Sodium phosphate P 32 has been used for this purpose for the past 25 yr. It uptake in skeletal tumor and in osteoblastic new bone adjacent to tumor can be markedly increased by pharmacologic stimulation using androgenic steroids, or during rebound deposition after a course of parathyroid hormone. Although efficacy in terms of subjective pain relief is high, more objective signs of success are often lacking, and survival, while more confortable, is not prolonged. Marrow depression is the most significant side effect. A beta-emitting, bone-seeking isotope, 89Sr, may have a better therapeutic/toxic ratio, and should receive further trial. Radiation-induced necrosis has also been applied, though more hesitantly, to the proliferative, destructive, but nonmalignant synovium in rheumatoid disease. Here, a number of colloidal preparations, most commonly 198Au, have been employed. Again, relief of symptoms, particularly recurrent joint effusions, is quite high, although the basic disease process is not reversed. The major hazard here appears to be leakage of material to regional lymph nodes, resulting in irradiation of circulating lymphocytes. Although chromosomal damage can be detected when such cells are then cultured, the actual consequences of this, if any, are not presently known. Both shorter-lived (165Dy) and longer-lived (32P) larger-size colloids are being evaluated, which may prove safer in this regard than 198Au.

Data on 544 patients with esophageal cancer are reported. The main reasons of their refusing the radical treatment were as follows: 1) a considerable local tumor proliferation (31.8%); 2) senile age, concomitant diseases, a general poor condition of patients (25.6%); 3) the presence of distant metastases (11.4%); 4) location of a tumor in the jugular or upper thoracic esophagus for which palliative radiotherapy was performed, but in some cases a palliative surgery (9.7%); 5) fear of surgery (15.4%); 6) no reason (6.4%).
