The reported incidence of malignant pheochromocytoma varies from series to series. In this series 4 cases (7.2 p. 100) were observed out of a total of 55. In two cases the tumour progressed rapidly but in the other two cases, metastases were detected 3 to 12 years after the apparent cure of a histologically benign pheochromocytoma. The urinary levels of catecholamines and their metabolites gave no indication of the underlying malignancy. The diagnosis was only made from the clinical and radiological detection of metastases (2 hepatic, 2 bone). There is no satisfactory treatment and various therapeutic methods have to be used in succession; surgery for a single metastasis, radiotherapy and antiadrenergic agents to combat clinical manifestations. The natural history of this tumour is relatively long.

Twenty-six patients with metastases from a germinal cancer of the testis were treated with Mithramycin. After an observation time of between one-half-3 one-half years, 18 are still alive, of which 12 appear to be free from cancer. The 2-year survival rate is 50% (5/10). The side effects of Mithramycin therapy are described and discussed.

One hundred and ninety-seven patients with measurable metastatic cancer of the colon have been treated with one of four anticancer drugs which have had little prior trial in this disease. Objective tumor responses lasting a median of 9 weeks occurred with 0.5 g/m of streptozotocin given intravenously every week (10 percent), 130 mg/m of CCNU given orally every 6 weeks (10%), 1.0 mg/kg/day of 6-thioguanine given orally (8%), and 3 mg/kg/day of procarbazine given orally (3%). Performance status declined more rapidly with streptozotocin and 6-thioguanine and the median survival time was less (12 and 16 weeks respectively) than with procarbazine and CCNU (23 and 20 weeks respectively). This study suggests that procarbazine given in this way is ineffective but trials of streptozotocin or 6-thioguanine combined with other agents active against colon cancer should ensue as well as further exploration of the usefulness of other nitrosoureas.

The investigation was performed by using 371 autopsy records collected by the Department of Pathology at Roswell Park Memorial Institute from 1956 till 1967. Only the "head and neck" tumors were taken into consideration. Two hypotheses were tested, i.e. whether metastases diffuse directly from the primary tumor throughout the body or if the metastatic process takes place in steps, requiring, in other words, that one or more organs be seeded first, before any generalized metastasis occurs. It appeared that the lungs and the lymphnodes of the neck are the two organs responsible for generalized metastases in the cancers of the "head and neck" area. The importance of the neck and lungs metastases in disseminating the disease was discussed in the text. It appeared that when metastases are present in the lymphnodes of the neck, the cancer is already generalized with and without metastatic deposits in the lungs. However, the absence of metastases in the neck is no guarantee that the disease is still localized to the "head and neck" area.

Between 1961 and 1974, 5,300 percutaneous, trans-thoracic needle biopsies under image intensifier control were carried out in the Karolinska Sjukhuset, Stockholm. These involved, 2,726 patients with localised intrathoracic disease. The indications, results and complications are discussed. Approximately 15% of cases were suspected of malignancy and showed peripheral infiltrates varying from 0.04 to 2 cm. diameter. Needle biopsy proved to be technically simple and relatively safe; it permits early diagnosis of bronchial carcinomas and solitary metastases with a high degree of accuracy and with few complications. It is assumed that, as a result, the prognosis in a large group of patients with bronchial carcinomas in the pre-clinical stage may be markedly improved.

Thirty-four cases of corticosurrenaloma with clinical onset before 15 years of age have been studied. Higher frequency in girls (65 percent of the cases) and in young age (80 percent before 5 years of age, 43 percent before 2 years), association with personal or familial other tumors and malformations, are noticeable features. Virilism is the major manifestation in children (83 percent of the cases), either isolated or associated with hypercortisolism and/or feminization. Hormonal assays are of little value, and the dynamic adrenal tests are of some help only in small tumors or isolated hypercortisolism. Radiological diagnosis by urography with cavography, arteriography, is easy in most cases. Evaluation of prognosis is very difficult. Clinical and biological data are not significant, histological data are often of little help. Only a very large mass, and occurrence of metastases (liver, lungs) evidence malignancy. This series does not allow to assess definitely the best therapeutic regimen. Surgery has to be performed as soon as possible. The effects of radiations have not yet been ascertained. High doses of op'DDD have led to a sustained remission of the tumor or metastases in 2 patients, and perhaps to a longer survival in 4 others.

In this study a state of temporary defibrinogenation was induced in rats by Defibrase treatment. It was found that the formation of pulmonary metastases after intravenous tumour cell injection was decreased in defibrinogenated rats. However, defibrinogenation did not influence the effect of trauma and infusion of dextran 1000 on metastasis formation. Both these procedures stimulated the formation of metastases in defibrinogenated rats. These results indicate, that fibrinogen and/or fibrin are of importance for the formation of metastases but that the stimulating effect of trauma and dextran 1000 on metastasis formation is independent of fibrinogen and/or fibrin.

From 1971-1973, 1046 patients underwent laparoscopy in the gynecological department; 256 of the cases were surgical problems. In contrast to gastroenterological laparoscopy, surgical laparoscopy was performed in the operating room under general anaesthesia and everything prepared for immediate surgery. Major surgical interventions--if necessary--were performed immediately after laparoscopy. Indications for surgical laparoscopy were the following: preoperative evaluation of nature, extent and eventual metastases of tumors. Preoperative differentiation of acute and chronic appendicitis from other affections, particularly in younger female patients. Suspected intraabdominal hemorrhage of traumatic or non-traumatic origin. Evaluation of pathological palpatory findings in the abdominal cavity. Differential diagnosis of chronic relapsing intraabdominal complaints of unknown origin. Differential diagnosis of putrid, tuberculous or carcinomatous peritonitis with eventual biopsy. Preoperative evaluation of questions concerning surgery of liver, gallbladder or pancreas in connection with occlusive jaundice, hepatic cirrhosis or malignancy. The results of this study show, that by laparoscopy in over 50% of the patients, major surgical interventions could be avoided. Contraindications were primarily limited to pulmonal or cardiac insufficiency. The only complication (intestinal perforation), was adequately dealt with under the given operative conditions.

We studied the effects of PS-K, a protein polysaccaride isolated from a basidiomycete, on the formation of blood-borne metastases. Experimental tumors were fifth-generation isotransplants of a spontaneous C3Hf mouse squamous cell carcinoma that was weakly antigenic. A single-cell suspension from fourth generation tumors was transplanted, and the tumor-bearing legs of the mice were amputated when transplants reached a certain diameter. Daily administrations of PS-K followed immediately, and both lungs were excised on the 21st postamputation day. The number of lung colonies formed on the surfaces of both lungs was counted and total volumes of metastatic colonies were estimated. PS-K, if administered alone, did not inhibit the lung colony formation. Marked reduction in this formation was observed when five daily doses of PS-K were administered simultaneously with cyclophosphamide. These observations indicate that PS-K may be a potent agent in the therapy of cancer if used as an adjuvant to a chemotherapeutic agent.

The in vitro cytotoxicity of lymphocytes from patients suffering from breast carcinoma against autochthonous, allogeneic and established breast carcinoma cells was evaluated. Lymphocytotoxicity to breast carcinoma cells was observed in all stages of the disease. Control lymphocytes from healthy donors or patients suffering from other carcinoma are not cytotoxic for the breast carcinoma cell lines. A follow-up study of the cell mediated immune reactions before and after surgical removal of the breast carcinoma showed that the cytotoxic lymphocyte population which is demonstrated in the presence of the tumor disappears quickly after excision of the carcinoma. The non-reactivity of lymphocytes is not due to a general immune defect. Serum of the tumor bearers did not block the lymphocytotoxicity in early stage breast carcinoma; in metastatic disease inhibition occurred in more than half of the cases. Preincubation of lymphocytes with antigen preparations of allogeneic breast carcinoma cells did not inhibit the cytotoxicity to breast carcinoma cells whereas autologous serum preincubated with the antigen preparation diminished the lymphocyte reactivity to the target cells in some cases.
