Expert Question

I have an 18year old rescue Mexican Red Head. He has been showing a choking motion or trying to push something down his throat. My vet did an upper gi on her. She said she either has esophical (sp) cancer or a fungus. She now wants to take a biopsy which I'm hesitant to do as the bird has to be under anestesia(sp).

If it is cancer and they use chemo to treat it, what are the odds that this would "cure" her. Do you recommend the biopsy or could we treat the fungus first and if it doesn't cure it, then we know it is cancer and then go to chemo treatments? Please let me know what you think asap. The doctor will be calling next week to make a decision. Thanks, Barbara

Expert Answer

Hi, Barbara, the answers to your questions and concerns best come specifically from your attending veterinarian. On-line, and in the absence of having examined your bird, viewed your diagnostic images and other diagnostic findings, it is functionally impossible to guide you with any succinct recommendations. 

Part of the reasoning behind a recommendation for obtaining a biopsy is specifically to confirm the nature of the disease process at the identified site. Should this be in the cervical esophagus, surgically obtained biopsies are comparatively easier as compared to lesions that are identified in the thoracic esophagus or glandular stomach. Cervical esophageal cancers are less commonly identified in the literature as compared to tumors lower in the gastrointestinal system, but if present, are more straight forward for potential for surgical removal. For the potential cancers that may be present, chemotherapeutic interventions and successful outcomes are uncommon, at best, in the literature. Oftentimes, with confirmed or strongly suspected cancer in that thoracic esophagus / glandular stomach area, treatments have been palliative with hopes only to comfortably extend quality of life. Your best prognostic hope is that the cause of the observed clinical signs is related to any other factor, excluding cancer.
