A system for staging the clinical status of patients with soft tissue sarcomas is presented, based on the clinical characteristics of the primary tumor (size, extension), the involvement of lymph nodes, the presence of metastases, and the grade of the tumor. This represents the TNM system with grade of tumor (G) added. The system evolved was based on examination of 1215 cases of 13 types of soft tissues sarcomas, primarily in the extremities (fibrosarcoma, liposarcoma, etc.). Nine stages are described, and they are correlated with survival in the cases reviewed. The staging system now can be used for case evaluation for therapy determination and for intercomparison of series of patients as to incidence of different kinds of tumors, effects of treatment, and survival.

After all records of patients with breast cancer who received primary treatment at Memorial Hospital in 1960 were reviewed, 304 women with operable, infiltrating carcinoma were identified and classified clinically according to the TNM system of the American Joint Committee for Cancer Staging and End Results Reporting. There were 66 patients (22%) classified under Stage I, 176 (58%) under Stage II, and 62 (20%) under Stage III. There were 82 patients (27%) in whom the nodal status was misclassified clinically. The observed 10-year survival was 59.7%. The 10-year end results (with 95% confidence limits) diminished significantly in relation to advancing clinical stage of disease--90.9% (+/-6.9%) for Stage I, 57.1% (+/-7.3%) for Stage II, and 33.9% (+/-11.8%) for Stage III patients. The 10-year survival in patients with pathologically negative axillary nodes was 71.5%, and in the patients with pathologically positive axillary nodes, 48.3%.

The growth rate of a mammary cancer can be calculated when a recurrence appears in the mastectomy scar. Growth rate can, at times, be approximated from the patient's history with reasonable accuracy. Approximately half of breast cancers exhibit rapid growth (tumor doubling time (Td), up to 25 days); one-third grow at an intermediate rate (Td 26 to 75 days) and 15% grow slowly (Td 76 days or longer). Anatomic (TNM) staging does not define a homogeneous patient group in breast cancer. Within each stage, there are rapid, intermediate, and slow-growing tumors. The prognosis varies importantly with the growth rate characteristics of the tumor. Survival is the product of the tumor doubling time and the number of tumor doublings through which the patient lives. Slowly growing and intermediate growth rate tumors are associated with a high percentage of 5-year survivors after mastectomy (between 80 and 100%). Rapidly growing tumors have few 5-year survivors. When survival after mastectomy is measured in the number of tumor doublings, the differences in survival of the three groups tended to disappear, indicating that in this select group of patients with scar recurrence there was no therapeutic advantage in any of the three groups, despite the differences in the survival times. The appreciable number of patients with tumors exhibiting slow or intermediate growth rates, in any series, suggests that the use of the 5-year interval is an inadequate measure of therapeutic response in breast cancer and may actually be misleading.

132 patients with advanced solid malignomas were treated with a combination of four cytostatic drugs (vinblastine, amethopterine, 5-fluorouracil and cyclophosphamid) given on one day. This was repeated once every 2-3 weeks. In every case the diagnosis was made histologically and the tumour was staged according to the TNM-system. The treatment of breast and ovarian cancer brought the best results, improved by a synchronisation therapy. Good results were achieved also in the treatment of special kind of sarcomas and of carcinoma of the urine bladder. The general condition of patients with colon carcinoma could be improved in about 30%. Only one patient died by drug-induced pancytopenia, otherwise severe side-effects were not noted. Before beginning the therapy the cell-mediated immunity of 31 patients was tested by skin-tests with tuberkulin purified protein derivative (PPD) and dinitrochlorbenzole (DNCB). Before and during cytostatic therapy PPD reactions were proven by 23 patients. In accordance to other authors we found that cell-mediated immunity is decreased in the advanced stage of malignoma. Further we noted that delayed hypersensitivity and the number of lymphocytes and monocytes in peripherel blood are important to prognosis and course in patients with cancer.

The fundamentals of applied oncology involve essential aspects: Intensive cancer prevention is necessary, which may be achieved by the elimination of certain environmental factors and the early recognition of premaligant and maligant growth processes, including an intensive fight against neglect and an extended health education. The WHO classification is an internationally understandable nomenclature. It is established and commented upon with regard to its specific application in practice. The importance of the dignity of tumour classes and types to prognosis and therapy is indicated. It is arranged in 7 qualities of dignity with corresponding types of neoplasms, with regard to transitional types between benign and malignant tumours. The definition of 4 tumoral stages according to the TNM system is intended for obtaining patient groups which permit to compare therapeutical results. The principle and application of the different therapeutical possibilites (surgical intervention, radiation therapy, chemotherapy, hormonotherapy, virus therapy, immunotherapy and complex treatment) are outlined. The rehabilitation and the after-care are of deciding individual, vocational and social importance to the resocialization of the tumour patients.

Complete documentation of the pathological spectrum of a great many similar cancer patients requires interdisciplinary coordination and the absence of ambition of any particular branch. The application of a TNM system devised by the authors for the classification of skeletal neoplasms showed in a retrospective study of 600 cases that the degree of infiltration into the periosteum and soft tissue, which opens more lymphatics to metastasizing tumor cells, is a more relevant parameter of the TNM system than the size of the tumor itself.

The choice of surgical and/or X-ray treatment of a laryngeal cancer is usually established by taking into consideration the site of the tumor and its extension. The histologic type is considered only when this is easily identifiable, whereas the histologic grade of cellular differentiation and the tumour-host relationship are always erroneously disregarded. These latter factors are of a basic importance in establishing a "tailor-made" therapeutic programme for each patient and the long-term prognosis. The above factors have led to a new critical approach to laryngeal cancer and have also made it possible to obtain some practical results: 1 degrees the correct definition of the verrucous squamous cell carcinoma of the larynx, which is the result of the highest local defensive reaction to tumour growth (mediated by thymus-dependent lymphocytes); 2 degrees a criticism of the present trend to perform a more conservative surgery decided only opon the basis of the site and extension of the neoplasm; conservation surgery must be adopted for patients with an intense cellular immune response around the tumour and with a moderate histologic grade of malignancy; 3 degrees a criticism of the present criteria in establishing the long-term survival, which do not include the early immune response; 4 degrees the necessity of a systematic histologic study of the surgical specimen so as to evaluate the intensity of the immune reaction both around the tumour and in regional lymph nodes. In the light of these new data, the TNM system of tumour classification is now outdated, as witnessed by the constant efforts to adapt it to the unpredictable behaviour of malignant disease.

A retrospective analysis of 206 patients with lip cancer is presented. Poorly differentiated primary lesions have a high rate of metastases. The metastatic potential of well differentiated lesions, when classified by size in the TNM staging system, is the same as that of intraoral carcinoma. A therapeutic approach is proposed.

The disease male breast cancer has been evaluated on the basis of data concerning 265 cases registered in Denmark over the period from 1 January 1943 to 1 July 1972. The data were obtained by review of hospital records, survey of microscopic preparations and examinations of surviving patients. The results are compared to results reported in the literature. The recent material is the second largest series hitherto published. Male breast cancer comprises 0.8 per cent of all cases of breast cancer in Denmark. The average age at establishment of diagnosis was 65.2 years in 257 cases of breast carcinoma, which is considerably higher than that found in women. The duration of symptoms in breast cancer is considerably longer in males than in females, 16 per cent having a duration of symptoms of 2 years or more. In only 13 per cent was a palpable tumour the only symptom on admission. Twenty-seven percent had ulceration. Ulceration and fixation to the underlying tissue are not, as commonly presumed, early symptoms in male breast cancer. According to the TNM classification, 35 per cent of 253 cases were in clinical stage I, 11 per cent in stage II, 42 per cent in stage III, and 12 per cent in stage IV. Duration of symptoms and histological grade of malignancy were of significant importance or the stage on admission. Assessed on the basis of the distribution into stages, the clinical appearance of the disease showed a significant improvement from the period 1943-1957 to the period 1958-1972. Attempts should be made to differentiate the disease from gynecomastia which is much more frequent. Only during the early stages of breast cancer, however, will there be differential diagnostic problems as the majority of patients do not present themselves until unequivocal clinical signs of malignancy are present. The series has been reviewed with regard to the presence of gynecomastia. Certain facts appear to support the theory that gynecomastia may be a premalignant state. A series of 30 patients with breast cancer were screened for the Klinefelter syndrome. One positive case was found. By pooling series of male breast cancer, in which such screening has been made, it was found that the incidence of the Klinefelter syndrome is higher among men with breast cancer than in the normal male population. Calculated on the basis of the general public were better informed about the existence of this disease and the value of its early diagnosis and treatment, the prognosis should undoubtedly by improved.

The immediate results of radical surgery for cardiac cancer were analysed in 438 patients. During a 20-year period the mortality rate made 23.3%. The analysis has shown that the results of treatment depend: 1) on gravity of the initial patients' state, judged by their distribution according to the degree of surgical risk, that could be estimated by the cancer spread, using TNM symbols necessitating suboperative biopsy; 2) on peculiarities of the operation per se (an approach, character, extent and technic of surgical intervention, and also degree of its being radical; 3) on a rational management of patients postoperatively and gravity of subsequent complications. The most objective criteria in estimating the immediate results of radical surgery for cancer of the cardiac gastric portion are described.
