Forty-three patients with disseminated germ cell cancer were treated with a combination of vincristine, Adriamycin, cyclophosphamide, actinomycin-D, and medroxyprogesterone acetate. All the 43 patients were considered evaluable for response. Thirty-one patients (72%) achieved a complete or partial remission and 14 (32.5%) achieved a complete remission. The patients who attained an objective response obtained a significant prolongation of life compared with the nonresponders (median survival 55 vs. 23 weeks). Responses were seen in all histologic categories and most frequently in patients with metastases confined to the lungs. The major side effects were leukopenia and stomatitis. There were no deaths related to toxicity of the chemotherapy.

A profile of acute phase reactant proteins has been studied in patients with cancer of the prostate as an aid to diagnostic staging and therapy control. A linear discriminant function analysis incorporating serum acid phosphatase, prealbumin, alpha1 antitrypsin, alpha1 acid glycoprotein and haptoglobin allows the correct identification of metastatic disease in 88.6% of patients. The profile may also serve to augment other parameters in the assessment of the physiological effect of oestrogen treatment and show whether the prescribed medication is being taken.

Serum AFP was determined serially by radioimmunoassay in 13 patients with ovarian germ cell tumors and in one patient with bilateral pure gonadoblastoma. There were 4 patients with pure dysgerminoma, one with pure endodermal sinus tumor (EST) and 8 with mixed germ cell tumors, all containing EST. The patients with dysgerminoma and gonadoblastoma had normal serum AFP at all times. All patients with tumors containing EST had raised serum AFP, although in most cases it was first determined between 1 and 3 weeks after operation and there was no evidence of metastases. Serum AFP became normal 5 to 7 weeks after operation and began to rise when disease recurred. Serum AFP determinations detected presence of recurrent disease long before it became detectable by other methods. Serum CEA was determined serially by radioimmunoassay in 8 of these patients, including 2 who dies with metastases, and was normal on all occasions.

Is seems indispensable, in consideration of the present investigation results, to revise our actual therapeutic conception for cancer therapy! While palliative cancer therapy was greatly successful, it was not possible to obtain any decisive improvement of cancer recovery rates (in relation to similar stages or tumor volumes), in spite of all the therapeutic endeavour through the last twenty or twenty-five years. From almost 3000 analyses of metastatic growth and from numerous other experimental or clinical observations results as an explication that surgical treatment itself, on certain conditions, may release a relatively great number of metastases. Thus, the failure of our therapeutical endeavor is programmed, too, by the treatment! Consequences for diagnostics, precautions and therapy are discussed.

1020 patients with early breast cancer were treated between March, 1970, and October, 1975, according to a prospective clinical trial. The results have been recorded after a follow-up of two to seven years. 713 cases of clinical stage-1 cancer were randomly allocated to treatment by simple mastectomy and postoperative radiotherapy, or simple mastectomy alone. There was no statistically significant difference in overall survival or in survival without distant metastases between the two groups. There was a significant reduction in the incidence of local recurrence in those who had received early postoperative radiotherapy compared with those who had not. 307 cases of clinical stage-11 cancer were randomly allocated to treatment by simple mastectomy and postoperative radiotherapy or radical mastectomy alone. There was no statistically significant difference in survival or in the incidence of local recurrence or distant metastases between the two groups.

Hypercalcaemia is often associated with malignant disease. Causes of elevated serum-calcium levels in the absence of bony metastases include parathyroid-hormone production by the tumour, osteolytic factors made by the tumour, and coexistent primary hyperparathyroidism. By measuring nephrogenous cyclic-A.M.P. excretion to assess parathyroid-hormone function, we have determined the mechanism of such hypercalcaemia in 15 patients. Nephrogenous cyclic A.M.P. ranges from 0.05 to 2.40 mumol/g of creatinine in normal subjects, from 2.27 to 8.45 mumol/g in patients with primary hyperparathyroidism, and from 0.50 to 1.30 mumol/g in patients with proven non-hyperparathyroid hypercalcaemia without malignancy. 9 patients (60%) with hypercalcaemia and malignancy had normal levels of nephrogenous cyclic A.M.P. (range 0.35-2.07 mumol/g creatinine). The other 6 (40%) had elevated nephrogenous cyclic A.M.P. (range 2.70-5.55 mumol/g) consistent with increased parathyroid-hormone secretion. Surgical exploration of the neck in these patients showed that the increased parathyroid-hormone secretion was secondary to primary hyperparathyroidism, not ectopic hyperparathyroidism. Thus, the data indicate that coexistent hyperparathyroidism may be common in patients with hypercalcaemia and malignancy and that the measurement of nephrogenous cyclic A.M.P. is very useful in identifying patients at risk for hyperparathyroidism.

57Co-Bleomycin (57Co-BLM) was used to visualize malignancies of the head and neck because it does not present the disadvantages of many other radiopharmaceuticals. In a series of 21 patients with 9 control subjects and 12 cases of tumors. 57Co-BLM showed a high and rapid uptake in primary site and metastases of malignant tumors of various histologic types, but not in benign tumors such as angiofibromas. Compared to 67Ga-citrate. 57Co-BLM has many advantages for tumor imaging in the areas of nose, pharynx and larynx: No background activity due to the concentration of 57Co-BLM in normal structures of the head and neck has ever been observed, as opposed to what happens with 67Ga-citrate. Furthermore, the blood clearance of 57Co-BLM is much more rapid than that of 67Ga-citrate, so that an early study may be performed in a 6-24 hr. interval instead of 48-72 hr. with 67Ga-citrate. 57Co-BLM scintigraphy is an easy, non-invasive and sensible diagnostic technique in determining the extent of malignant tumors in ORL patients.

Admixture of androgen-sensitive elements from normal or hyperplastic prostatic tissue interferes with biochemical studies of prostate cancer in its primary site. Heterogeneity of cancer tissues, varying in stromal and epithelial elements, also complicates interpretation of data relating to androgen metabolism. Accordingly, we have compared metastatic deposits composed of epithelial cancer cells to the primary biopsies of 4 patients in respect to uptake of 3H-testosterone and its conversion to 5-alpha-dihydrotestosterone during in vitro incubation. 3H-testosterone uptake was similar for both tissue sites but 3H-dihydrotestosterone formation was reduced by 76% in the metastases compared to primary tissues. This group was not large enough to show statistical significance, whereas a total of 11 such primary studies compared to 6 metastatic specimens was significant. When either primary or secondary tissue results were compared to 12 cases of benign prostatic hyperplasia similarly studied the differences were highly significant. These results demonstrate a major impairment in the formation of dihydrotestosterone by metastatic prostatic cancer and a similar but less evident alteration in the primary site. This abnormality in testosterone metabolism is of major importance in the attempt to obtain effective hormonal control of human prostatic cancer.

Percutaneous transhepatic intubation and combined internal-external drainage of the biliary system was performed in 15 patients with occlusion of the extrahepatic bile ducts due mainly to cholangiocarcinoma, metastases of the hepatoduodenal ligament, and tumors of the periampullary region. The technique is described and the value of the procedure in temporary decompression and combined internal-external bile drainage prior to radical surgery is demonstrated. Its advantages as a palliative method are evident in far-advanced malignancy when extensive and complicated surgical procedures are ill-advised.

The studies reported here explore the relationship between tumor-specific transplantation antigens (TSTA) and (1) the expression of serologically defined specificities, and (2) the immunogenicity of H-2K- or H-2D-determined alloantigens on methylcholanthrene (MCA)-induced murine fibrosarcomas. Expression of H-2K and H-2D serologically-detected private specificities on groups of tumors raised in B10.A, B10.BR or B10.D2 strains varied greatly among tumors. No regular reciprocal or direct relationship to tumor TSTA strength was found. Each tumor, however, expressed H-2K or H-2D alloantigens stably as determined by direct cytotoxicity or absorption techniques. Even those tumors expressing little or no detectable alloantigen by serologic analysis were immunogenic in H-2K or H-2D incompatible congeneic hosts. This was assayed in terms of capacity to evoke primary or secondary tumor resistance, and to induce allo-antibody toward private H-2K or H-2D end specificities. An exception was that B10.BR tumors failed to induce anti-H-2Dk antibody despite strong surface alloantigen expression. While TSTA strength did not correlate with serologically detected alloantigen expression, TSTA strength did tend to correlate inversely with capacity to resist primary growth in the H-2K different host, and directly with resistance in the H-2D different host.
