[Experience with the use of a low-calorie diet in breast cancer patients to prevent metastasis]. / Opyt primeneniia nizkokaloriinoi diety u bol'nykh rakom molochnoi zhelezy s tsel'iu profilaktiki metastazirovaniia.

The paper discusses results of three-year follow-up of breast cancer patients keeping to a low-calorie diet after radical mastectomy and chemotherapy. The diet was planned according to age, energy expenditures and body weight and was aimed at a 15% decrease in the total caloricity as compared to corresponding individually-tailored norms for healthy people. This was achieved by reduction in fat (by 30%) and carbohydrates (by 9%). To assure the diet on the domiciliary basis, patients were provided with a table of nutrients for all food products available. Regular examination failed to show any adverse effects of the dietary restrictions on the general status of patients. However, an inhibiting effect of the diet on progression of disease was established, with recurrence being registered in 25% of controls (in 13 out of 52 patients) and only 7% of the study group (in 4 out of 56 cases).

[Effect of electron-acceptor compounds on the immunoregulatory mechanisms and ATPase activity of the erythrocyte membranes from patients with inoperable lung cancer]. / Vliianie élektronaktseptornykh soedinenii na immunoreguliatornye mekhanizmy i ATPaznuiu aktivnost' membran éritrotsitov krovi neoperabel'nykh bol'nykh rakom legkogo.

In 55 inoperable patients with lung cancer the use of tinidizole and metronidazole with X-ray therapy intensified the immunoregulative disbalance, increased the quantity of circulative immune complexes and reduced the Na+K+-ATPase activity of erythrocyte membranes in contrast to the data obtained from patients receiving only X-ray therapy. Thus the data obtained may be the basis for the use of the correcting therapy in inoperable patients with lung cancer.

The activity of erythrocyte membrane Ca2+, Mg2+-ATPase (EC 3.6.1.3) was studied in 22 patients suffering from lung cancer. The enzyme activity was found to increase. The observed changes indicate significant disturbances in the mechanisms of ion transport in organs and tissues during tumour growth.
