Multiple squamous cell neoplasms of the esophagus were induced in 24 inbred F344 rats by sc injection of N-methyl-N-benzylnitrosamine at a dose level of 2.5 mg/kg weekly for 20 weeks. All of these rats also developed papillomas, 67% developed pedunculated papillary carcinomas, and 63% developed carcinomas that invaded the wall. Of 191 total neoplasms, 66% were papillomas, 17% were papillary carcinomas, and 17% were carcinomas that invaded the wall. The neoplasms were well differentiated with various degrees of keratinization. Anaplastic areas were found in most lesions, but were more common in carcinomas. Neoplasms that invaded the wall were sessile, with prominent intraluminal growth, or infiltrating, with predominant intramural growth. Penetration through the wall was observed, but neither metastases nor invasion of adjacent tissues was found. In addition to neoplasms, atypical endophytic proliferation of basal and spinous cells was observed in some of these rats. Proliferative or neoplastic changes were not observed outside the upper gastrointestinal tract.

Receptors for progesterone were found in 27% of 98 human breast tumours, and for oestrogen in 57% of 191 tumours. With one exception, progesterone receptors were found only in tumours which also contained oestrogen receptors. Levels of oestrogen receptor in positive tumours rose significantly with patient age whereas progesterone receptors were unchanged. Progesterone receptor levels were lower in lymph node metastases than in primary tumours, and oestrogen receptor levels were lower in large tumours (greater than 5 cm diameter) compared to small lesions. Receptor levels were not significantly correlated with circulating concentrations of either oestrogen or prolactin. The implications of receptor measurements in assessing hormone responsiveness of breast tumours are discussed.

Primary osteosarcoma of the fifth sternebra is reported in a 6-year-old male Great Dane. Presenting signs were suggestive of myocarditis and pulmonary congestion. Electrocardiography revealed R waves of low and variable amplitude and the plasma alpha-hydroxibutyrate dehydrogenase level was elevated. Radiography revealed neoplasia of the fifth sternebra with extensive bilaterial pulmonary metastases. Histologically the neoplasm showed typical osteosarcoma with plentiful osteoid production.

Levels of alkaline phosphatase were measured in the primary tumor of 26 patients with osteosarcoma. One of seven patients with a tissue alkaline phosphatase level less than 0.6 microM/min/mg developed pulmonary metastases. In contrast, 16 or 17 patients with a tissue alkaline phosphatase level greater than 0.6 microM/min/mg developed pulmonary metastases. It thus appears that tissue alkaline phosphatase levels of primary osteosarcomas are strongly correlated with prognosis (p less than .01).

In three experiments, 87%, 75%, and 85% of female C57BL/6N mice developed pulmonary metastases by 50 days after amputation of legs having autochthonous 3-methylcholanthrene-induced sarcomas. No difference in the incidence of pulmonary metastases was observed when autochthonous tumors of short (49--94 days) and longer (95--119 days) latency periods were compared. These metastasizing autochthonous tumors may provide a useful model for studies of metastases and for the evaluation of cancer therapy in a minimal residual disease setting.

Until chemotherapy is proved more effective in the initial management of squamous cell cancer of the mouth and throat, radiation and surgery will remain the principal treatment modalities. This paper documents a treatment selection process which is used in the Head and Neck Clinic of the Peter MacCallum Hospital. Anatomical resectability, potential of control by radiation, disability and deformity produced by surgery, presence of metastases, psychological factors, and concurrent disease, as well as tumour behaviour, are all factors which influence the choice of radiation or surgery, alone, or in combination, in the treatment of each patient.

The cyclic chemotherapy scheme OS I/75 was tried in 6 patients with newly diagnosed osteosarcoma and in 3 patients with secondary metastases. The treatment consists of high dose methotrexate, followed by citrovorum-factor rescue, doxorubicine (Adriblastin) and cyclophosphamide (Endoxan). All 6 primary patients are in a continuous remission of 6+ to 21+ months (median 12+ months). The length of remission in the patients with metastases is 5.5+ and 8+ months. The haematological side effects led to an average prolongation of the cycle by 11 days in a planned cycle duration of 42 days. However, they were readily manageable. Among the other side effects two cases of Adriblastin myocardiopathy are remarkable which became apparent after methotrexate and ifosfamide. In order to improve possibilities for treatment regional centralisation of patient care and interdisciplinary and supraregional cooperation of treatment centres are necessary. A prospective treatment programme has been developed for the Federal Republic of Germany and Austria.

Sixty-eight patients suffering from conjunctival melanoma were treated by beta-irradiation. The dose given ranged between 15,000 and 20,000 rd at the tumor surface. In 75% the therapy was successful. In 67,4% the melanoma could be cured by beta-irradiation alone with a follow-up period between three and ten years. The lethality rate from proven metastases was only 6.2%. The regression time after beta-therapy, as a rule, exceeded several months. Beta-rays can be used either primarily or after tumor excision. Care should be taken that the applicator covers all the tissue containing tumor cells.

In this study the presence of an amyloid A, antigenically related material was determined in four subpopulations of human leukocytes. Monocytes, granulocytes, thymus-derived lymphocytes, and bone marrow-derived and null lymphocytes were isolated from the peripheral blood of five apparently normal subjects, two patients with secondary amyloidosis, three patients with acute infections, and seven patients with metastatic cancer. Mononuclear leukocytes, isolated from the interface of a Ficoll-Hypaque gradient, were separated into monocytes, thymus-derived lymphocytes, and bone marrow-derived plus null lymphocytes by glass adherence and depletion of sheep erythrocyte rosette-forming lymphocytes. Granulocytes were isolated by sedimentation in 2% methyl cellulose from the erythrocyte-rich pellet formed at the bottom of the Ficoll-Hypaque gradient. The four isolated leukocyte subpopulations were cultured and, at varying intervals, the amyloid A content of the culture medium and of sonicated, 2 x 10(6) cells was determined by radioimmunoassay. Our results indicated a 2-14 times greater amount of amyloid A-related material in the sonicated granulocytes compared with the individuals' serum amyloid A levels. The mononuclear subpopulations showed a low or negligible amyloid A content. The amount of amyloid A antigenic material was further found to increase in cultured granulocytes, reaching a peak value between the 16th and 30th h of culture. The granulocytes of only two out of eight individuals tested released amyloid A antigenically related material into the culture medium. This release was found to be blocked by the presence of colchicine, vincristine, puromycin, or cycloheximide in the culture medium. In contrast, only the presence of puromycin or cycloheximide was shown to significantly inhibit the intracellular increase of amyloid A in the cultured granulocytes. Thus, it appears that among the circulating blood cells, the granulocytes produce amyloid A antigenically related material and could release it under conditions that remain to be further defined.

Two groups of patients with advanced cancer of the prostate received adjuvant immunotherapy by direct intra-tumor injection of BCG. The first group had advanced metastatic disease that was failing to respond to conventional hormone therapy. The second group were new cases of stages III and IV tumor who were previously untreated and who had had a transurethral resection of the prostate and orchiectomy followed by BCG immunotherapy. The clinical and pathologic findings for both groups of patients are described.
