Chemotherapy Drugs, applied like a cream on your sarcoid This may be an effective treatment for certain types of sarcoid. Chemotherapy drugs, injected into the sarcoid This is a treatment that we sometimes use on more resistant sarcoid cases, when they are especially severe. Chemotherapy drugs are not appropriate for every sarcoid, especially for those in which creams would be rubbed easily into other, more sensitive tissues. Immunotherapy may be effective in treating sarcoid tumors around the eyes, but it requires multiple treatments, usually with a lot of sedation.
Trauma A sarcoid a will make it worse, it may involve surgery or applying a cream, and then there is a regimen of treatments. If treatment is stopped before removing sarcoid, a high risk exists for it recurring, sometimes with an even worse lesion than when originally presented. It may take as long as 32 weeks of treatment to get rid of a sarcoid, which is unpalatable to some horses. Larger sarcoid tumors can be surgically debulked before starting the other forms of treatment.
In addition, many sarcoid infections that are originally thought to be relatively benign can become disseminated after the veterinarian has specimend them or treated them. Overall, prognosis is poor due to sarcoid tendencies to return despite treatment, which may be expensive. One of the biggest problems with sarcoid is its propensity to regrow after treatment, often more aggressively than the original tumor.
Because they are so varied in type and severity, there is not one treatment option that works best for every patient. Sarcoids are the most common skin cancers of horses, and because of their higher recurrence rate following treatment, better treatment options are needed. Equine Sarcoids are the most frequently diagnosed tumors of the equine species, comprising 20% of all equine neoplasms and 36% of all skin cancers in horses.
Sarcoids are the most common skin cancers of horses and ponies, and while they can appear as warts, they are locally disruptive and are a form of skin cancer. Mixed Sarcoids are more prevalent in geldings than mares, with the majority occurring initially in horses aged 3-6 years. Although Sarcoids are generally not considered to be life-threatening, they may be disfiguring and unpleasant to a horse, depending partly on where the tumor is located.
Mixed Sarcoids – A single horse might only have one type of sarcoid, while another horse might have a mix of multiple types. Some types of sarcoid, which your veterinarian would feel comfortable identifying simply by appearance, and would give you advice accordingly. When considering treatment options, your vet will take into account many factors, including type of sarcoid, how aggressive it is, location and size, how well your horse or pooch is likely to tolerate any given treatment, and many others.
If you suspect that your horse has sarcoid, a good first step is to call a veterinarian, who can apply a trained, knowledgeable eye to the situation and, if needed, suggest biopsy. If you have a horse with a suspected sarcoid tumor, you might become overwhelmed with all of the obvious treatment options, including the stories of older wives and the suggestions of other horse owners.
If you purchase a horse with sarcoid, insurance companies will refuse to cover the treatment because it is a pre-existing condition, and it may turn out to be expensive. Taking a biopsy without removing the whole sarcoid may cause it to become more aggressive, so we begin treatment based on location and the nature of the lesions most of the time. Excision of small, well-localized lesions with a clean margin of normal tissue surrounding the sarcoid is a helpful treatment.
A small sarcoid in an area that has a lot of loose skin and does not rub against the dressing is easier to manage and less troublesome than a sarcoid in a more sensitive area. Nodular sarcoid that can be lifted away from the underlying tissue is usually just treated with rubber band ligation. Generally, if the ring can pass all the way around the sarcoid and not fall off, that is the first course of treatment.
In one study, the sarcoid located around one horses eye, which was unable to be removed by surgery without removal of its eyes, was treated by electroporation with calcium, which had complete responses. They noted a better response rate was seen with the un-biopsied lesions, suggesting trauma from the calcium electroporation alone did not worsen sarcoid disease in eight horses. The researchers said that although calcium electroporation is viable, dispersing the calcium into tough sarcoid tissue may be challenging.
To assess the effect of the therapy on fully regressed sarcoid numbers, Fishers exact test was used. For all continuous data (sarcoid diameter, sarcoid surface area, and VAS score), the effects of time and treatment on the dependent variables were determined using repeated measures ANOVAs with horse as the blocking factor. Because more than one sarcoid would have been treated similarly in a single horse, each treatment group needed at least 15 horses.
All horses who were brought to the surgery and anaesthesiology department at Ghent Universitys Faculty of Veterinary Medicine for the treatment of a previously untreated, non-visible, or partially-verrucous, equine sarcoid were considered for the study. Horses with fibroblastic or nodular sarcoid tumors as well as occult and/or partially verrucous tumors, and horses who received concurrent veterinary care for other indications, were excluded. When multiple occult or partially verrucous tumours were present in a single horse, all tumours were treated with the same product.
Six out of 27 (22%) sarcoid tumors were totally eliminated with treatment, while another six sarcoid tumors (22%) were reduced by over 30%. As nine horses had more than one lesions, a total of 47 sarcoid lesions were treated with daily topical applications of aciclovir cream over two to six months; four horses had surgery to remove the lesions prior to treatment. As a compensation for participation in the trial, treatments and consultations were offered at no charge, and sarcoids that were treated with placebo during the trial were treated afterward at no extra charge.
