The results obtained in irradiation of 106 patients with metastases of different malignant tumors in the skeleton are reported. Radiotherapy was carried out on a distance gamma-apparatus by two fractions, with a single dose of 650 or 850 rad. As a result of the therapy, pains disappeared in 32 patients, and in 60 patients these were diminished considerably. A prompt therapeutic effect of the method, its simplicity and effectiveness (an opportunity to raise the capacity of the apparatus and clinic where a patient stays) made it possible to recommend it for practical purposes of palliative irradiation.

The authors studied tissue reactions in the regional lymph nodes of 68 patients with an invasive cancer of the uterine cervix at stage I and II of neoplastic disease. Two basic types of the lymph nodes reactions have been distinguished. In the first type of changes a reactive hyperplasia of sinusoidal histiocytosis predominated, as well as distinct activation of lymphocyte production within the follicles and numerous aggregates of plasmacytoid cells within the medullary cords. The second type of reaction was characterised by fibroplastic reaction causing constriction and block of capsular lymphatic and blood vessels, the pseudotransformation into hemolymph node and hematoxyphilic atrophy of lymphoreticular tissue. The authors' observations indicate that in case with the predominance of the second type reaction within regional lymph nodes arise favourable conditions for the production of distant metastases.

As tables show, hormone treatment may be useful for control of the growth of endometrial and mammary cancers. Although endocrine treatment is to be used only where metastasis has already occurred 70% of all breast cancer patients eventually reach this stage, lending importance to endocrine treatment as well as chemotherapy as life-lengthening (though not curative) methods. Control of tumor growth is possible through altering the hormonal milieu of the host organ and through direct influence on the tumor cells. Measures may be ablative (removal of hormone-producing glands) or additive (e.g., use of steroids, as shown in detail in the tables). Progestagen, in high doses, produces atrophy of the endometrium and is associated with objective remission in at least 30-40% of cases of progressive endometrial carcinomas. In breast cancer cases, endocrine treatment is most suitable for premenopausal women or women at least 5 years past menopause; location of the metastases is among the other factors to be considered.

Evidence for a thyroid origin of tumorous metastases may be facilitated by a histochemical determination of colloid. It is supported by the presence of proteins, demonstrable especially by the reaction for tyrosine, and a simultaneous absence, or only traces of acid mucosubstances. Contrary to existing literary reports, an intraplasmatic formation of mucin has been detected in certain thyroid carcinomas and their metastases. The most difficult to diferentiate histochemically from thyroid colloid is the secrete of certain adenocarcinomas of the prostate.

Regan isoenzyme, variant alkaline phosphatase, and alpha-fetoprotein were found in the serum of a patient with gastric cancer. The histology of the tumor was tubular adenocarcinoma. There were metastases in the retroperitoneal lymph nodes, but not in the liver. The liver was normal microscopically, with no evidence of bile duct obstruction. alpha-Fetoprotein in the tumor tissue was detected by immunoprecipitation reaction in agar. Regan isoenzyme and variant alkaline phosphatase were also detected in the tumor tissue and total alkaline phosphatase activity of the tissue was very high. These findings suggested their tumor origin.

Leukocytes from patients with limited cancer display LAI reactivity whereas leukocytes from patients with metastatic cancer frequently demonstrate no reactivity in the tube LAI assay. The leukocytes (monocytes) of reactive patients react with tumour antigen through specific cytophilic anti-tumour IgG antibody bound to the monocyte's Fc cell surface receptors. The non-reactive monocytes from patients with advanced cancer lacked the ability to bind free cytophilic anti-tumour antibody. Moreover, the serum of the non-reactive patient contained no free cytophilic anti-tumour antibody capable of "arming" normal leukocytes. The serum of patients with large tumour burdens contained free tumour antigenic determinants capable of absorbing free cytophilic anti-tumour antibody from the serum of reactive patients or when preincubated with reactive leukocytes abrogating their LAI responsiveness immunologically specifically. Blocking was immunologically specific; therefore, the specificity must reside in the tumour antigenic determinant since immune complexes are bound nonspecifically. The tumour antigen coat was removed by gentle trypsinization of the monocyte's surface. This restored the monocyte's capacity to react with the sensitizing tumour antigen and to bind free cytophilic antibody from the microenvironment. Nonreactivity in the tube LAI assay of patients with metastatic cancer was not the result of a numerical deficit of circulating monocytes but was mediated by an excess of tumour antigen in the microenvironment of the sensitized monocyte.

There were 22 patients with vertebral metastases and impending neurologic damage from prostatic, vesical and renal cell carcinoma treated by decompressive laminectomy combined with local radiotherapy and chemotherapy. The neurological recovery was complete in the prostatic carcinoma patients (10 of 10), partial in the vesical carcinoma patients (2 of 5) and unsatisfactory in the renal cell carcinoma patients (1 of 7).

The best combination of methods for managing primary breast cancer may not yet be known. Radiation therapy has been proved effective in decreasing the incidence of local and regional recurrence following mastectomy. Thus, until a superior regimen is established, I recommend local and regional irradiation for patients at high risk for recurrence. Local irradiation is also an effective means of achieving palliation of symptoms associated with metastatic disease.

Of 145 women with metastatic breast carcinoma who survived palliative surgical castration, 40.7% had objective remission and another 11.0% had subjective improvement. Favorable response was more frequent in ovulating patients who had small masses of recurrent tumor in fewer locations, with skeletal spread especially well tolerated. Palliation appeared to be related to the site of metastatic disease and numbers (mass) of metastatic sites, but not to the age of the patient, tumor histology, or the disease-free interval. Survival was better for the patients who showed improvement after castration. Such improvement may predict continued relief from the use of other modalities of systemic treatment.

The pyrimidine analog, 5-azacytidine (NSC 102816), was administered by continuous intravenous infusion in Ringer's lactate in increasing doses to sets of patients with metastatic cancer to establish a dose sufficient to produce mild toxicity. Twenty-one patients (23 trials) were treated with doses of 50-200 mg/sq/m/day for 5 days every 2-4 wk. Nausea and vomiting were moderate and easily preventable. Doses of 100-200 mg/sq/m for 5 days every 14 days produced granulocytopenia, usually after two courses. Less toxicity was observed when courses were given every 21-28 days. Forty-five patients with previously treated and refractory acute myeloblastic leukemia were treated. The majority received doses of 150 mg/sq m for 5 days every 2 wk. Eleven (24%) complete remissions and four partial remissions were observed. The number of courses to achieve remission averaged three and required an average of 59 days. Nine patients with blastic crisis of chronic myeloblastic leukemia and four with refractory acute lymphoblastic leukemia failed to respond. 5-Azacytidine administered by continuous infusion is well tolerated and is an active compound in acute myeloblastic leukemia.
