[Tumors of the breast in old age].

After reviewing the literature on this topic the authors studied all patients admitted to the Institute of Surgical Pathology I at the University of Pavia for breast cancer between 1-1-1974. An analysis of the findings revealed that: (a) Out of 993 patients with breast cancer, 204 (20.54%) belonged to the geriatric age group (> 65 years old) and of the latter 135 (66.

[Leukocyte adhesiveness and chemotaxis during infusion of Intralipid].

The effect of an intravenously administered lipid emulsion (Intralipid) on granulocyte functions has been studied. The study has been carried out in 20 healthy individuals, divided into two groups: 10 individuals have been infused with Intralipid 10% i.v.

Evaluation of possible causes of delayed hypersensitivity impairment in cancer patients.

The separate roles of malnutrition, advanced age, and stage of tumor growth as causes of impairment of delayed hypersensitivity response (DHR) was studied in 111 patients with solid tumors and in 56 nonneoplastic control patients matched for age, anatomical site of disease, degree of illness, and nutritional status. Pretreatment DHR to recall antigens (tuberculin, Candida, streptokinase-streptodornase, trichophyton) and to dinitrochlorobenzene in cancer patients with 9% anergic, 43% hypoergic, and 48% normoergic; the distribution of DHR in controls was not significantly different. In cancer patients, the serum albumin level showed an inverse correlation with the stage of tumor (p less than 0.

Nutritional and immunological evaluations in cancer patients. Relationship to surgical infections.

Several reports provide evidence of the synergism between malnutrition and infection in hospitalized patients. In this study, preoperative complete nutritional assessment (NA) was performed to: 1) evaluate NA modifications in 21 controls with benign minor surgical diseases and in 71 surgical cancer patients; 2) determine the relative value of nutritional and immunological indicators in relation to the postoperative septic complications in cancer patients. The following parameters were used: percent weight loss/month, percent standard arm circumference, percent standard triceps skinfold; hematocrit, hemoglobin, serum proteins, albumin, iron, transferrin, ceruloplasmin, retinol binding protein (RBP); serum creatinine, urine creatinine, creatinine/height index, percent arm muscle circumference; peripheral lymphocytes, white blood cells, complement (C3c), skin tests.
