ELECTROCHEMOTHERAPY - STATISTICS.
ECT is applied in three ways: sole, adjuvant or intra-operative therapy. The mode used depends on the site and extent of the tumour. In the graphs below the disease-free survivals of 219 patients are shown. Vertical drops mark recurrences, small vertical lines indicate latest report without recurrence for individual patients. The graphs can be enlarged by clicking on them.
Where surgery is not possible or has unacceptable functional or cosmetic sequelae and where the tumour is small enough, ECT can be used alone. This was used in 89 cases in all. The graph below shows disease-free survival.Click image to enlarge
All adjuvant treated
Where surgery had been performed but the histopathology report showed that there was tumour tissue at the margins of tissue removed, ECT was applied about 2 weeks post-op. This was carried out in 64 cases.Click image to enlarge
Where tumours were relatively large, the bulk of the tumour was removed surgically and ECT was applied to the operation site and margins before suturing. There was often, but not always, some wound breakdown in these cases. There were 66 of these cases in all to date.Click image to enlarge">
Canine mast cell tumours
All but one canine mast cell cases had grade 2 tumours. Many were in difficult site such as the paw, muzzle or perianal. 62 patients were treated for mast cell tumours, some had multiple tumours treated.Click image to enlarge
Squamous cell carcinomas
40 patients were treated for SCC in various sites.Click image to enlarge
Spindle cell tumours
Fibrosarcomas, haemangiopericytomas, nerve sheath tumours and soft tissue sarcomas can be bundled with spindle cell tumours. 87 patients had this class of tumours.Click image to enlarge
