Below is an update on the condition of 4-year-old thoroughbred racehorse Lost in the Fog, prepared by David Wilson, veterinary professor and director of the Large Animal Clinic at UC Davis' Veterinary Medical Teaching Hospital. Wilson and a team of veterinary specialists from UC Davis examined Lost in the Fog Thursday at Golden Gate Fields near San Francisco to evaluate his condition.

Lost in the Fog was brought to UC Davis' Veterinary Medical Teaching Hospital on Aug. 13 with a suspected case of colic. However, diagnostic tests revealed the horse has lymphoma with tumors detected on or near his spleen.

*** Lost in the Fog Update -- Sept. 1, 2006

Veterinary specialists Gary Magdesian, Larry Galuppo, Mary Whitcomb, Suzanne Brenner and David Wilson traveled to Golden Gate Fields near San Francisco on Thursday, Aug. 31, to examine Lost in the Fog and repeat the abdominal ultrasound examination in conjunction with Don Smith, the horse's veterinarian, who was present for the entire procedure.

Lost in the Fog was very bright, alert, comfortable, eating well, and physically looked very good and in good spirits. He has not shown any signs of abdominal discomfort this week. The tumor in his spleen and the second tumor high in the abdomen between his kidneys and below his spinal column have not changed in size during the past two weeks, and no new tumors were detected in the spleen or liver or other abdominal or thoracic organs.

These findings indicate that the dexamathasone treatment has controlled the previously rapid growth of the tumors but has not caused them to shrink.

The location and size of the tumor high in the abdomen precludes the possibility that it can be removed surgically; however, chemotherapy remains an option, with the goal of inducing remission of the tumor masses.

Lost in the Fog's trainer, Greg Gilchrist, and Dr. Smith are currently weighing the potential benefits of chemotherapy against potential adverse side effects and will engage in further discussions with UC Davis veterinarians Gary Magdesian and Alain Theon before making a final decision regarding whether to embark on chemotherapy.
