Endocrine-induced regression of cancers.

Cancer is not necessarily autonomous and intrinsically self-perpetuating. Its growth can be sustained and propagated by hormonal function in the host which is not unusual in kind or exaggerated in rate but which is operating at normal or even subnormal levels. Hormones, or synthetic substances inducing physiologic effects similar thereto, are of crucial significance for survival of several kinds of hormone-responsive cancers in man and animals. Opposite sorts of change of the hormonal status can induce regression and, in some instances, cure such cancers. These modifications are deprivation of essential hormones and hormone interference by giving large amounts of critical compounds. The control of cancer by endocrine methods can be described in three propositions: (i) Some types of cancer cells differ in a cardinal way from the cells from which they arose in their response to change in their hormonal environment. (ii) Certain cancers are hormone-dependent and these cells die when supporting hormones are eliminated. (iii) Certain cancers succumb when large amounts of hormones are administered.

Improved detection of hepatitis B surface antigen (HBsAg) in blood donors by monoclonal radioimmunoassay.

We evaluated the performance of a monoclonal radioimmunoassay (M-RIA) with enhanced sensitivity and high specificity for hepatitis B surface antigen (HBsAg) in blood donors. The results were compared to a conventional RIA that used polyvalent antibodies (P-RIA). Analysis of 6409 American blood donors not reactive by P-RIA revealed an additional 1.4 HBsAg-positive donors per 1000 by M-RIA, or an approximate 60 percent, improvement in HBsAg detection rate. Furthermore, in 995 Israeli blood donors negative by P-RIA, 11 additional HbsAg-positive donors were identified. The 55 percent improvement in detection rate was similar to that observed with American blood donors. Since several of the newly identified HBsAg-positive blood donors had antibodies to the core antigen (anti-HBc) as the only serologic evidence of recent or past hepatitis B exposure, we studied an additional 68 anti-HBc-positive individuals with the M-RIA. It was found that 26 percent (18/68) reacted only by M-RIA and not by P-RIA. These findings suggest that there are blood donors with HBsAg undetectable by P-RIA.
