Surgery, RT, CHT have increased curability Precocious diagnosis and adequate FU have permitted early diagnoses of primary and relapses Cronicization is the goal in a lot of patients The hope of target therapy (magic bullet) is failing
Cancer has a more complex origin than what we know Not only genic alteration saves cancer, but also tumor milieau, metabolic changes and weak host defence Hyperthermia might attack many known and still unknown targets

The use of parachutes to prevent major trauma due to gravitational challenge after jumping out of an aircraft has not been proven in any randomised controlled trial But there are a very small number of anecdotal reports of people surviving falls from planes flying at considerable heights And the use of parachutes is not without the risk of their own inherent complications

"$!1*) The optimal salvage therapy for Relapsed Ovarian Cancer (ROC) has not been clearly established. Response to second-line chemotherapy is low, with a short median survival (8.8-15 months). We investigated the effect of a combined approach consisting of Intraperitoneal administration of Cisplatin and Paclitaxel and whole abdomen hyperthermia (EH)
"$!1*) Intraperitoneal administration of Cisplatin and Paclitaxel is very active against epithelial ovarian carcinoma and showed superior activity than i.v. chemotherapy Armstrong et al New Engl J Med 2006
"$!1*) In animal model and human pharmacokinetic studies, high intraperitoneal drug concentrations and exposure and high peritoneal tumour concentrations were achieved The combination of intraperitoneal chemotherapy with whole abdomen hyperthermia enhances the penetration and cytotoxic activity of cisplatin and induces high response rate Phase II clinical trials suggest a possible increase of i.p. chemotherapy efficacy by transient applications of hyperthermia Jones E et al,, Int J Hyperthermia. 2006

3!( Whole abdomen hyperthermia was administrated by arrangements of capacitive electrodes applied on the abdomen with a radiofrequency field of 13.56 Mhz (Oncotherm). Treatment was carried out at an applied adsorbed power of 80-150 Watt In all patients the number of cumulative equivalent minutes at 43 degrees C exceeded by 90% of monitored points within the abdomen (CEM 43 degrees C T(90)) as a measure of thermal dose.
Intratumor temperatures were measured by 4 thermocouples inserted through angiocatheters which were placed 5 cm to 12 cm deep into the tissues. If tumours were not reachable the thermocouples were applied in the 4 abdominal quadrants
