In
questa pubblicazione ad opera di ricercatori coreani, si manifesta una
acclarata associazione tra utilizzo del telefono cellulare e neurinoma del
nervo acustico.
Nello
studio si evidenzia come, prendendo in considerazione gli elevati utilizzatori
e l'ispilateralità, il dato di aumento del rischio quasi quintuplica ! O.R=4.5 e si ricorda come i 10 anni di utilizzo, con almeno 20 minuti al
giorno, le 2000 ore cumulative rappresentino un fattore dirimente nella
valutazione degli effetti.

ABSTRACT
Vestibular schwannomas (VSs) grow in the region where
the energy from mobile phone use is absorbed. We examined the associations of
VSs with mobile phone use. This study included 119 patients who had undergone
surgical tumor removal. We used two approaches in this investigation. First, a
case-control study for the association of mobile phone use and incidence of VSs
was conducted. Both cases and controls were investigated with questions based
on INTERPHONE guidelines. Amount of mobile phone use according to duration,
daily amount, and cumulative hours were compared between two groups. We also
conducted a case-case study. The location and volume of the tumors were
investigated by MRI. Associations between the estimated amount of mobile phone
use and tumor volume and between the laterality of phone use and tumor location
were analyzed. In a case-control study, the odds ratio (OR) of tumor incidence according
to mobile phone use was 0.956. In the case-case study, tumor volume and
estimated cumulative hours showed a strong correlation (r(2) = 0.144,
p = 0.002), and regular mobile phone users showed tumors of a markedly larger
volume than those of non-regular users (p < 0.001). When the analysis was
limited to regular users who had serviceable hearing, laterality showed a
strong correlation with tumor side (OR = 4.5). We found that tumors may
coincide with the more frequently used ear of mobile phones and tumor volume
that showed strong correlation with amount of mobile phone use, thus there is a
possibility that mobile phone use may affect tumor growth.
