被撤回的出版物: Bleomycin/interleukin-12 electrochemogenetherapy for treating naturally occurring spontaneous neoplasms in dogs (Retracted article. See vol. 17, pg. 826, 2010)

On the basis of superior outcomes from electrochemogenetherapy (ECGT) compared with electrochemotherapy in mice, we determined the efficacy of ECGT applied to spontaneous canine neoplasms. Intralesional bleomycin (BLM) and feline interleukin-12 DNA injection combined with translesional electroporation resulted in complete cure of two recurrent World Health Organization stage T2bN0M0 oral squamous cell carcinomas (SCCs) and one T2N0M0 acanthomatous ameloblastoma. Three remaining dogs, which had no other treatment options, had partial responses to ECGT; one had mandibular T3bN2bM1 melanoma with pulmonary and lymph node metastases; one had cubital T3N0M1 histiocytic sarcoma with spleen metastases; and one had soft palate T3N0M0 fibrosarcoma. The melanoma dog had decrease in the size of the primary tumor before recrudescence and euthanasia. The histiocytic sarcoma dog had resolution of the primary tumor, but was euthanized because of metastases 4 months after the only treatment. The dog with T3N0M0 fibrosarcoma had tumor regression with recrudescence. Treatment was associated with minimal side effects and was easy to perform, was associated with repair of bone lysis in cured dogs, improved quality of life for dogs with partial responses and extended overall survival time. ECGT seems to be a safe and resulted in complete responses in SCC and acanthomatous ameloblastoma. Cancer Gene Therapy (2010) 17, 571-578; doi:10.1038/cgt.2010.13; published online 23 April 2010
