Domestic shorthair cat – 16 years old
Calvin presented unable to defecate with a firm colonic mass at the pelvic inlet.
Exploratory laparotomy surgery is performed with resection of a colonic mass and colocolonic anastamosis. Biopsy revealed a colonic fibrosarcoma. Calvin did well for 11 months but clinical signs returned and evaluation revealed that the mass had returned. The prognosis was grave because surgery to remove the mass was high risk or not possible due to the tumors size and location. The owners sought an alternative therapy.
X-ray prior to ThermoWave treatment reveals a large pelvic fibrosarcoma with colonic obstruction. (Note large colon and pelvic mass).
ThermoWave therapy administered for 1 hour at 41°C over the distal colon and pelvic canal immediately after giving Carboplatin I.V. at a dose of 200mg/m2. ThermoWave therapy was continued for 8 more sessions roughly every other day (Mon, Wed, Fri) with heat applied to the area of the distal colon and pelvic canal for one hour at 41°C.
04/04/2011 (Monday 4th week – 9th session)
ThermoWave therapy was administered for 1 hour at 41°C over the distal colon and pelvic canal immediately after again giving Carboplatin I.V. at a dose of 200mg/m2.
Two days later (Wednesday, 4/6/2011)
ThermoWave therapy was administered for 1 hour at 41°C over the distal colon and pelvic canal alone. This completed a standard ThermoWave protocol.
However, since ThermoWave's heat and strong electromagnetic field can kill cancer cells under 1 cm and stimulate the immune system, we heated the kidney and thymus/heart hilar lymph node region (heart base) was heated for 10 minutes each at therapeutic temperature of 41°C for 4 more sessions every other day to further stimulate the immune system and destroy any small cellular metastasis that may have be present.
Note a greater than 50% reduction in the size of the pelvic mass with return to normal function after about 1 week of ThermoWave therapy.
Calvin's quality of life has been maintained, and his is his usual grump self...not bad for a 16 year old cat with a grave prognosis!
