The evidence that the principles of surgical adjuvant chemotherapy developed in experimental animal systems also apply to a variety of neoplastic diseases in man has been clearly demonstrated. Micrometastatic disease can be eradicated with effective chemotherapy in several diseases. Prolongation of disease-free interval, if not cure, is now possible in diseases in which curative surgery alone or in combination with radiotherapy does not achieve these goals. The previously fatal childhood solid tumors--Wilms', Ewings' sarcoma, embryonal rhabdomyosarcoma--are curable in a high percentage of patients appropriately treated with combinations of surgery, radiotherapy, and chemotherapy. The prolongation of the disease-free interval in osteogenic sarcoma has permitted consideration of entirely new surgical approaches for this tumor in which radical amputation has traditionally been employed. The spectacular results achieved in the treatment of Stage II breast cancer may potentially save hundreds of thousands of lives in the coming decade. Clinically recognizable metastatic disease is rarely curable by any currently available treatment modality. The prolongation of disease-free intervals and production of cures when surgical adjuvant chemotherapy is employed may be partly explained by relatively more circulation, and thus drug delivery to each tumor cell, more favorable cellular kinetics, and a healthier and more immunocompetent host who is better able to withstand drug effects on normal tissues, and to participate in tumor destruction. Cures of certain patients with neoplastic diseases using surgical adjuvant chemotherapy has increased the incentive to learn more about new and old drugs and their effective use alone and in combination. Chemotherapy, in appropriate combinations with surgery, radiotherapy, and immunotherapy, may well be more efficacious in many clinical situations than the traditional use of single-modality treatment. The data presented in this paper relate solid evidence that the possibility of cure in a variety of neoplastic diseases is real.

Eighty-five patients with a diagnosis of minimal breast cancer were evaluated. The predominant lesion was intraductal carcinoma, and axillary metastases occurred in association with minimal breast cancer in seven of 96 cases. One death occurred due to minimal breast cancer. Bilateral mammary carcinoma was evident in 24% and bilateral minimal breast cancer in 13% of the patients. The component lesions of minimal breast cancer have varied biologic activity, but prognosis is good with a variety of operations. The multifocal nature of minimal breast cancer and the potential for metastases should be recognized. Therapy should include removal of the entire mammary parenchyma and low axillary nodes. The high incidence of bilateral malignancy supports elective contralateral biopsy at the time of therapy for minimal breast cancer.

Breast cancer in association with pregnancy and lactation is rare, but presents a therapeutic problem of considerable magnitude. The outlook for such patients is less favorable than that of nonpregnant, nonlactating women, probably because the stage of the disease is more advanced when it is discovered. The most significant factor in the poorer prognosis is physician delay in diagnosis and therapy. When mastectomy is carried out early in pregnancy, the operation can be as effective as in nonpregnant women of the same age groups. It is emphasized that when pregnancy and breast cancer are found concurrently, prompt therapy for the cancer should be undertaken. Interruption of pregnancy in nondisseminated breast cancer is of little value. If pregnancy is near term when the diagnosis of disseminated breast cancer is made, the desire of the husband and wife for a child should be considered. A modest delay in therapy to allow for delivery probably has no deleterious effect. Castration should be withheld and used only for the patient with metastatic disease. There may be a place for prophylactic castration in the treatment of disseminated disease, but its role is yet to be clearly defined. Subsequent pregnancies in a patient with axillary spread at the time of mastectomy are contraindicated, because of the high rate of treatment failure and decreased rate of survival. In patients desiring future pregnancies following mastectomy, a period of observation of at least 2 years seems wise. At the end of that period, if clinical evaluation, laboratory values, roentgenographic studies, and isotopic bone scanning are negative for disseminated disease, subsequent pregnancies seem safe. Prompt evaluation of any breast mass found during pregnancy and lactation should be carried out by needle or operative biopsies under local anesthesia. Although the prognosis of the pregnant or lactating woman with breast cancer is generally favorable, numerous long-term survivals are encountered in those women who undergo prompt mastectomy early in pregnancy. The former pessimistic outlook for such patients seems unjustified. With modern methods of diagnosis and treatment, therapy can be effective and successful.

Blocks of axillary lymph nodes from 78 patients with invasive breast cancer, which after "routine" pathological examination were regarded as negative for metastases, were step-sectioned at 20 u intervals. Occult metastases were detected in 24% of the cases. A significant association between such metastases and a lack of or slight degree of an intraductal carcinomatous component of the dominant cancer was noted. There was no relationship between occult metastases and 15 other histopathological and 3 clinical features investigated, including an average 5 year survival rate. Similarly there was no correlation between any of the possible discriminants investigated in the 24% of patients who have died of their diseases or are living with recurrence regardless of the presence of occult metastases. Factors accounting for the lack of universal survival in patients with Stage I (and those with occult metastases that might be designated as stage 11/2) remain enigmatic. It is concluded that attempts to detect occult metastases by extending histopathological methods may be more academic than practical or therapeutically significant.

A colony of mice suffering from dominant hemimelia associated with agenesis of the spleen has been developed and characterized during the past 7 years. The hereditarily asplenic (Dh/+) mice have a very low incidence (9%) of spontaneous mammary tumors (SMT). Asplenic (Dh/+) females were mated with mice homozygous (nu/nu) for hereditary athymia (nude) having a BALB/c background. BALB/c females heterozygous for the nu gene and with spleen (nu/+,+/+) have a moderate incidence (12%) of SMT, whereas nu/+,Dh/+ breeders have a drastic increase in the incidence of SMT to 46% when bred under identical conditions. Since all parent strains have a very low incidence of SMT, it appears that the spleen agenesis is a major factor accounting for an earlier and higher incidence of SMT in hereditarily asplenic (nu/+,Dh/+) mice than in normal (nu/+,+/+) siblings. The SMT express mammary tumor virus antigen(s) and possess estrogen, progesterone, and glucocorticoid receptors. The SMT rapidly metastasize and kill the host within 30 to 45 days. The BALB/c asplenic mice with SMT represent a unique model relevant to human breast cancer and for study of the function of the spleen in the development of solid tumors in general and of SMT in particular.

Thirteen patients who were referred to the Oncology Unit with the diagnosis of metastatic cancer to the choroid were studied and found to have other conditions. All of the patients were female. Nine of the 13 had a history of systemic cancer of which 6 were breast cancer. Five patients were currently being treated with chemotherapeutic agents for their systemic cancer. Three of the 13 patients had bilateral fundus lesions. The most common diagnostic entities confused with metastatic disease were either inflammatory or hemorrhagic lesions of the retina. The preceding history of cancer in the patient with a puzzling fundus lesion may predispose the referring ophthalmologist to suggest a diagnosis of metastatic cancer to the choroid.

The case of a 65 old woman who had a rapidly progressive neurologic symtomatology is reported. The autopsy disclosed a carcinoma of the breast with metastases in brain, cerebellum, brainstem, pituitary, thyroid gland and the adrenals. The frequency of the pituitary metastases is discussed, especially in cases of breast cancer. The macro and microscopic aspects of the metastatic pituitary gland are studied.

There are indications that the status of hormone receptors in breast cancer tissue is related to the success of chemotherapy to treat breast cancer. Remissions are recorded in 60% of the cases of endocrine treatment of patients with positive evidence of cytoplasmic hormone receptors. It must be kept in mind, however, that any given cancer tissue sample is not representative for all metastases locations. Depending on the hormone receptor content of each section, different parts of the tumor could react differently to hormone treatment, and even sections with the same receptor content can react differently to treatment. The criteria for the determination of a remission are too strict. The carbon absorption method or the more common agargel electrophoresis can be used to determine the level of receptor content in a tissue sample.

Histopathology data from 298 patients with breast cancer have been stored in a computer, and features influencing survival have been analysed by the life table method and presented in survival curves. Prognostic features assessed were the size, type, and grade of neoplasm, the amount of stromal elastosis and lymphocytic infiltrate, and the presence and number of axillary metastases. The most reliable indications of short survival are the presence of axillary metastases and a high tumour grade. These two features are correlated, as high-grade tumours are much more likely to have metastases at presentation. No statistical difference is found in the survival of patients with metastases in one or two axillary nodes compared with those with larger numbers involved. There are differences in survival in different types of carcinoma; the well-differentiated infiltrating duct carcinoma with tubular pattern has the best prognosis, followed by the medullary carcinoma. The size of the tumour has some prognostic significance, but this is outweighed by its grade.
