I have a tentative idea about a possible cancer therapy by stimulation
of sympathetic nerve with a NCP(Neuro Cybernetic Prosthesis).

Here below the basis for this idea are provided,

1.Anticarcinogen N-benzyladriamycin-14-valerate (AD198) can induce
apoptosis by activation of protein kinase C-delta. Many studies in
vivo and in vitro have already proved that N-benzyladriamycin-14-
valerate (AD198) have a better antitumous effect than adriamycin.
（1.2.3.4） Some study showed that N-benzyladriamycin-14-valerate
(AD198) have a weak inhibition effect on topoisomerase II and have a
weak binding to DNA. N-benzyladriamycin-14-valerate (AD198) can
activate PKC-delta following by its binding to deltaC1b domain.（5.6.7）

2.Some studies showed that PKC-a induce the apoptosis following by its
activation of K-Ras.（8）

3.cAMP and its analogues 8--Br--cAMP、8--Cl-cAMP can induced
differentiation  of many kinds of cancer cells ,also can suppress
tumor cell growth .（9.10.11.12.13.14）

4.It was reported that nervous tissue are found in tumors.（15.16）

The neurotransmitter noradrenalin releaseed from sympathetic nerve
endings can activate PKC-a and PKC-delta by its interaction with a1
and B receptors, as well as production of cAMP following by activation
of adenylcyclase.

Therefore, it's theoretically possible and feasible to treat cancer
and kill cancer cells by stimulation of sympathetic nerve.

For instance, hepatoma was treated by the stimulation of the
sympathetic nerve which innervated liver by NCP(Neuro Cybernetic
Prosthesis).
