title: Periodicity in metastatic tumour growth demonstrated in the human liver at autopsy. Preliminary report.
abstract: The present study is based on 1,069 autopsies made up of stomach, breast, renal and colonic cancer. Periodicity is described in the liver weight index (liver weight/body height) at death in patients with liver metastases. The seasonal variation tended to be more marked in females and among older patients, and it differed with tumour type. A period with maximum deaths tended to follow that of maximum liver weight index. A periodic difference previously reported in a small series of malignant melanomas is thus not an isolated phenomenon. This indicates that basic biological pathways concerned with the control of tumour growth may be involved. How the system works remains an open question.
