sarcoma virus (FeSV)
S0093 - Ultrasensitive qualitative detection of feline sarcomavirus by
real time polymerase chain reaction
sarcoma viruses (FeSV)
arise as a result of recombination of feline leukemia virus (FeLV)
with parts of the host cell genome. The recombinant viruses have
deletions rendering them unable to replicate without the help of
wild-type FeLV. However, because these recombinant viruses still
contain a mutated cellular oncogene as a result of the recombination,
they are capable of causing tumors, mainly of fibroblastic cells.
FeSV has been reported
worldwide, but it is uncommon. FeSV-induced tumors are seen only in
cats persistently infected with FeLV. Since the tumors usually contain
both FeLV and FeSV, the tumors are transmissible experimentally, but
there is no evidence that natural cat-to-cat transmission occurs. In
fact, FeSV is found almost entirely in the tumor itself, and only
wild-type FeLV is shed from affected cats.
usually appear as multiple, ulcerative or nodular, non-healing skin
lesions, which recur after surgical excision. Metastasis to internal
organs may occur late in the course of the disease. All affected cats
have FeLV viremia. Unlike spontaneous fibrosarcomas of cats, which are
usually solitary and seen in older cats, most FeSV-induced tumors are
seen in cats 1-7 years old.
Diagnosis is usually
based on history, FeLV status and histological confirmation of
fibrosarcoma, although complete confirmation of the diagnosis requires
extensive laboratory studies, performed by PCR or other methods (Deim
et al., 2008).
