Cancer Archeology paper - Hosein Kouros-Mehr


Interesting article in Plos One describing discovery of metastastic carcioma in a young male who lived in Sudan in 1200 BC.  While not necessarily shedding light into the mechanisms of cancer metastasis, the paper presents interesting novel archeological data that can be used for future historical analyses.  The mechanisms that drive metastasis are likely to be as old as the mechanisms that drive normal development.

Abstract


Cancer, one of the world’s leading causes of death today, remains almost absent relative to other pathological conditions, in the archaeological record, giving rise to the conclusion that the disease is mainly a product of modern living and increased longevity. This paper presents a male, young-adult individual from the archaeological site of Amara West in northern Sudan (c. 1200BC) displaying multiple, mainly osteolytic, lesions on the vertebrae, ribs, sternum, clavicles, scapulae, pelvis, and humeral and femoral heads. Following radiographic, microscopic and scanning electron microscopic (SEM) imaging of the lesions, and a consideration of differential diagnoses, a diagnosis of metastatic carcinoma secondary to an unknown soft tissue cancer is suggested. This represents the earliest complete example in the world of a human who suffered metastatic cancer to date. The study further draws its strength from modern analytical techniques applied to differential diagnoses and the fact that it is firmly rooted within a well-documented archaeological and historical context, thus providing new insights into the history and antiquity of the disease as well as its underlying causes and progression.

Authors

  • Highlights
  • RTEL1 is an Fe–S helicase that controls homologous recombination by dismantling D-loop intermediates.
  • RTEL1 maintains telomere integrity by disassembling T-loops and counteracting G4-DNA structures.
  • RTEL1 variants strongly associate with predisposition to glioma, astrocytoma, and glioblastoma.
  • Mutations in RTEL1 give rise to Hoyeraal–Hreidarsson syndrome.
