A review of over 400 primary bone tumors yielded 11 lesions with features allowing classification as malignant fibrous histiocytoma on a purely histological basis. Correlation with roentgenograms and clinical data indicated that these tumors occurred as osteolytic lesions associated with a high incidence of pathologic fractures in the metaphyses of skeletally mature long bones. Nine patients developed pulmonary
metastases
and 3 developed lymph node
metastases
within 21 months following diagnosis. The average survival was 12 months in 6 of the 9 patients who had no secondary treatment in their
metastases
. Treatment of 3 patients with metastatic lesions with chemotherapy or radiotherapy has been clinically encouraging. Some evidence was obtained that either or both the histiocytic and fibroblastic component may
metastasize
. There is a need for biopsy of metastatic lesions and autopsy followup to more accurately assess the mode of spread and histologic type of the
metastases
.

Paralleled clinical studies of radioisotopic imaging or tumor
metastases
in the bone were undertaken with Tc99m pyrophosphate, Ga67 citrate, and Tc99m sulfur colloid. All three were capable of anticipating the bone roentgenograms. A critical analysis suggested that positive delineation with Ga67 citrate would sometimes be superior to the others. This deserves further investigation. Clinically the combined use of Tc99m pyrophosphate with Ga67 for the chest areas and extremties or with Tc99m colloid for the pelvic and abdominal areas would be more frutiful in early detection and exact localization of bone metastases.

In 30 cases of breast-cancer, including 24 primary cases, the tumor-associted fibrinolysis was investigated using agar plate method. In 60% of the tissue sample fibrinolytic activity was found. No activity could be detected in the remaining 40%. There was evidence of a positive correlation between tumor-associated fibrinolysis and tumor size as well as the rate of axilla
metastases
. Among the fibrinolytic active cases there was a disproporionate number of adenocarcinoma, whereas in the inactive collective the solid and scirrhous carcinoma prevailed. There was no relation between the tumor-associated fibrinolysis and the percentage of tumor cells in the tissue. The firbinolytic inactive tumors showed a better histopathological adaptation to the surrounding tissue than the active ones. There was less small-cell infiltrate in the stroma of the fibrinolytic active tumors than in the inactive cases. No significant difference was found in the form of growth and the occurence of fibre structure. For clinical assessment a longer period of observation and a larger study are necessary.

To evaluate the presence or absence of hepatic
metastases
or primary hepatoma 106 patients were examined by liver scintigram as well as laparoscopy or laparotomy. A definite diagnosis was established in all patients by histology, autopsy or observation of clinical course for at least one year. Only scintigrams resulted in false positive diagnosis (in 5%). False negative diagnoses were obtained in 29% of laparoscopies and in 36% of scintigrams when evaluated routinely with knowledge of the clinical findings and laboratory examinations. Analysis of the same scintigrams by an experienced examiner without knowledge of the clinical findings lowered the proportion of false negative scintigrams to 12%. In 5 patients with liver metastases or hepatoma coexisting in liver cirrhosis or advanced chronic liver congestion, both methods of examination gave false negative results.

One hundred and seven patients with carcinoma of the lung underwent immunologic testing, and 62 of these patients were randomized to an immunotherapy protocol comparing the effects of Pasteur strain BCG, either alone or combined with allogeneic tumor cells, to the effects of no immunotherapy. Patients with residual disease left at the time of surgery or with
metastatic disease
at the time of diagnosis showed no increase in survival as a result of this form of immunotherapy. An insufficient number of patients with less advanced disease, in whom we would expect the most beneficial effect, have been entered in this study. In general, we were unable to document substantial effects of immunotherapy on the immunologic parameters tested. Only in recall antigen skin testing was there a statistically significant increase in reactivity in the immunotherapy groups. Tests of general immune status appeared to have a predictive value in monitoring lung cancer patients. Anergic patients had a poorer prognosis than did patients who demonstrated skin test reactivity. Patients with normal percentages of lymphocytes (T cells) forming rosettes with sheep erythrocytes at 29 degrees C were generally normal in other tests of immune competence. In serial studies of rosette formation, all patients who developed recurrent disease had a pattern of depressed or falling rosette values, and these abnormalities occurred an average of 3.1 months prior to clinical detection of recurrence. Patients with large-cell anaplastic carcinoma were found to have a significantly higher incidence of depressed rosette levels than the other histologic types. Both large and small-cell anaplastic patients had significantly depressed lymphocyte proliferation by mitogens and allogeneic cells. Although lung cancer patients have been described as immunologically depressed, they are capable of recognizing tumor-associated antigens. When tested in leukocyte migration inhibition assays with tumor-associated antigens, the majority of the patients in our study were found to be reactive. The use of a 3 M KCl extract of pleural effusion cells from a patient with pulmonary adenocarcinoma has given good reactivity and specificity in lung cancer patients of all histologic types. In addition, these patients have been shown to respond in a mixed lymphocyte/tumor interaction to tumor-associated antigens (Dean, 1976b).

The accumulation of bone-seeking radiopharmaceuticals in extraosseous lesions has been reported in patients with myocardial infarctions, cerebral infarctions, and some soft-tissue tumors. While the precise mechanisms involved remain uncertain, the spectrum of abnormalities exhibiting such accumulation increases. In our laboratory, 99mTc-diphosphonate concentrated in four hepatic tumors (one cholangiocarcinoma and three
metastases
from colon carcinoma). This property of phosphate-related radiopharmaceuticals has not been reported previously. Awareness of the possibility of focal diphosphonate accumulation in the liver should help avoid confusion with right lower rib-cage metastasis or pleural effusion.

A new histochemical method is described for the differentiation of mucins that utilizes two different Schiff reagents and allows single section identification of side chain O-acylated, and nonacylated, sialic acids in contrasting colors. In the event of mucins containing only one type of sialic acid, it may allow their specific identification (e.g., C7 or C8 side chain O-acylated). It has been shown to be useful in the identification of some
metastases
from adenocarcinomas of colon (where the primary is potassium hydroxide/periodic acid-Schiff positive) and should prove of great value in the investigation of diseases of the gastrointestinal tract and particularly those of the colon. It should also be valuable in the general field of epithelial mucin histochemistry, particularly for those mucins of the salivary and parotid glands, etc.

A primary pulmonary tumour in a four year old boy arising from the subpleural zone of the lung is described. It contains both stromal and epithelial elements at the primary site and in the bony
metastases
. The combination of the age of the patient, the site of the tumour, the stromal and epithelial elements present in the tumour suggest that this is a true pulmonary blastoma. Electronmicroscopy showed the presence of intranuclear viral particles.

Angiographic findings in one giant cell carcinoma, one cystadenocarcinoma, one poorly vascularized mucinous cystadenocarcinoma, as well as in two avascular (gastrin- and glucagon-producing) islet-cell tumors of the pancreas are described. Two hypervascularized islet-cell tumors are presented for comparison and a case of tumorous chronic pancreatitis in a child is reported because ot its rarity. The aggressiveness of the giant cell carcinoma of the pancreas was demonstrated by its expansive growth. In the case of cystadenocarcinoma angiography revealed the tumor with hepatic
metastases
not diagnosed at explorative laparotomy. The relative hypovascularity in the case of mucinous cystadenocarcinoma was unusual. Both avascular islet-cell tumors simulated a pancreatic pseudocyst and the final diagnosis was made only by immunoassay. Chronic pancreatitis in a child presented with marked hypervascularization.

Two cases of carcinoid adenomata of the bronchus in children are added to 25 previously reported cases of bronchial adenomata in children in the literature. Carcinoid tumors represent close to 50 per cent of bronchial adenomata in children, with cylindromas (adenoid cystic) forming 13 per cent and mucoepidermoids two per cent. Over 1/3 of bronchial adenomata have
metastases
at the time of diagnosis. No cases of carcinoid syndrome have been reported in children. The treatment of choice is lobectomy with sleeve resection or, failing that, pulmonary resection. The overall five-year survival time varies from 50 to 80 per cent and is enhanced by surgical resection.
