Epidemiological study (observational study)

A sentinel case series of cancer patients with occupational exposures to electromagnetic non-ionizing radiation and other agents.

Published in: Eur J Oncol 2011; 16 (1): 21-54

Aim of study (acc. to author)

A case series of cancer patients with occupational exposures to electromagnetic non-ionizing fields and other agents was reported by a medical unit in Israel. Furthermore, the hypothesis that latencies for all tumor types were coherently related to high occupational exposures starting at young ages should be examined.

Eligible 47
Other: 47 cancer patients with 55 tumors

Conclusion (acc. to author)

Overall, 47 cancer patients (40 male, 7 female) with different cancer types were presented. 15 patients developed cancer with latent periods between first occupational exposure to electromagnetic fields and diagnosis of cancer of less than 5 years, 12 patients with latent periods between 5 and 10 years, and the remaining 20 patients had longer latent periods. Many of the patients were young (7 patients under 20 years and 17 patients between 20 and 29 years) and had extremely short latent periods, especially for hematolymphatic tumors and testicular cancers. The fact that latent periods for testicular cancer were very short, for hematolymphatic tumors longer and solid tumors still longer suggests a coherent and biologically plausible pattern of latency in relation to the onset of exposure to electromagnetic fields and other agents.

Limitations (acc. to author)

The case series is based on relatively small numbers. Exposure was assessed by interview. No measurements were conducted and other electromagnetic field sources such as mobile phones were not included.
