“…The most common breed in this study was the Shetland sheepdog; dolichocephalic dogs accounted for 93.8% [2,5,6,11,[13][14][15]. In this study, both the mean and median age of tumor occurrence were 10 years, which was similar to those previously reported [2,3,9,11,[14][15][16].…”

Prognosis of Canine Patients with Nasal Tumors According to Modified Clinical Stages Based on Computed Tomography: A Retrospective Study

et al. 2008

ABSTRACT. To evaluate the efficacy of clinical staging based on computed tomography (CT) imaging over the World Health Organization (WHO) staging system based on radiography for nasal tumors in dogs, a retrospective study was conducted. This study used 112 dogs that had nasal tumors; they had undergone radiography and CT and had been histologically confirmed as having nasal tumors. Among 112 dogs, 85 (75.9%) were diagnosed as adenocarcinoma. Then they were analyzed for survival time according to each staging system. More than 70% of the patients with adenocarcinoma were classified as having WHO stage III. The patients classified under WHO stage II tended to survive longer than those classified under WHO stage III. Dogs classified under WHO stage III were further grouped into CT stages III and IV, and CT stage III patients had a significantly longer survival time than CT stage IV patients. In addition, patients treated with a combination of surgery and radiation had a significantly longer survival time than the patients who did not receive any treatment in CT stage III. On the other hand, different treatment modalities did not show a significant difference in the survival time of CT stage IV dogs. The results suggest that WHO stage III dogs may have various levels of tumor progression, indicating that the CT staging system may be more accurate than the WHO staging system.

“…The mean age of the reported cases is similar with previous studies, which have reported a mean age of onset of nine to 10 years [5,8,14]. The prognosis for paranasal tumors without any treatment is poor and euthanasia is chosen in most animals as a result of progressive local invasion of tumor and related problems within three to six months of the onset of clinical signs [18].…”

“…Epitelial tumors which are different type of carcinomas constitute 51 to 75% of nasal tumors. The remaining tumors mostly originate from connective tissue, cartilage or bone [5][6][7][8]. Dolichocephalic and mesocephalic breeds are more prone to nasal tumors [1].…”

Objective of this study was to report Magnetic resonance imaging (MRI) features of histologically confirmed paranasal sinus tumors and surgical outcomes. Totally 17 dogs and 3 cats were included in the study. Medical records of dogs and cats which were presented between January 2008 and November 2015 due to paranasal sinus tumors were reviewed. Dogs and cats were included if they have full clinical findings, diagnosed by MRI, confirmed histologically, and treated just surgically. Collected data for sex, breed, age, tumor stage, localisation, surgical outcomes, histological diagnosis, survival time and cause of death were included. Soft tissue mass within the nasal cavity replacing the nasal conchae and/or ethmoturbinates and mass invading to the frontal sinuses were determined in 80% (n=16) of the cases in MRI. Nasal and/or frontal bones were destructed in 65% (n=13) of the cases. In 7 dogs bone flap was created to expose and remove the tumor, and the flap was replaced wired after operation. In 10 dogs and 3 cats frontal and/or nasal bone was involved by the tumor, and closure of the defects was carried out with PMMA and wire. In this case series 50% of the tumors were sarcomas, and it was followed by adenocarcinoma (20%) and neuroesthesioblastoma (15%) in decreased rates. Dedicated MRI examination is crucial for diagnosis of paranasal sinus tumors, and surgical intervention as sole treatments looks acceptable for providing better quality of life for certain time.

“…The radiographic diagnosis of inflammatory, infectious, and neoplastic lesions within the nasal cavity can be challenging, as radiographic signs are non-specific 16 . Radiographic signs of diseases of the nasal cavity and sinuses demonstrate a spectrum of appearances ranging from minor increases in soft-tissue opacity to lytic bone lesions and expansible masses 8,13,16,17 . Non-destructive patterns are characteristic of acute bacterial and viral infections, early foreign body reactions, nasal haemorrhage, oedema, and LPR, while a destructive pattern is more suggestive of fungal infection or neoplasia.…”

Chronic nasal disease is a common problem in dogs. To determine the aetiology, a retrospective study in 75 dogs with persistent and chronic nasal disease was done. All dogs were evaluated by means of survey nasal radiographs, antegrade and retrograde rhinoscopy, bacterial and fungal cultures, and histopathology. A definitive diagnosis was made in 74/75 cases (98.6 %). Nasal neoplasia was the most common diagnosis (46.7 %), median age 108 months, followed by lympho-plasmacytic rhinitis (20 %), median age 112 months, and fungal rhinitis (10.7 %), median age 53.5 months. Other diagnoses included nasal foreign body (5.3 %), median age 51 months, and primary bacterial rhinitis (6.7 %), median age 116.5 months. Rare aetiologies identified were nasal polyps, granulomatous rhinitis, oro-nasal fistula and naso-pharyngeal stenosis. This study showed that by using a structured combination of survey radiography, rhinoscopy, cultures and histopathology, a diagnosis could be made in dogs with chronic nasal disease.
