Introduction: Lingual neoplasia uncommonly affects dogs, yet the morbidity associated with these tumours is high. Surgical excision is often the treatment of choice, but outcomes after tumour resection are rarely reported. The purpose of this study was to describe the signalment, tumour type, tumour location and outcome in a cohort of dogs undergoing resection of lingual neoplasia. Methods: This study was performed multi-institutionally utilizing the combined caseload of VSSO members. Medical records of dogs diagnosed with lingual neoplasia were reviewed and variables recorded included signalment, tumour type and location, and outcome. Statistical analysis of the recorded variables was performed. Results: Fifty-two dogs were included (23 males, 29 females). Tumour types were primarily squamous cell carcinoma (n = 19) and malignant melanoma (13); however, 20 cases of 11 other tumour types were also noted. Tumours were found in the cranial (n = 12), middle (17), caudal (7), cranial/middle (7) and middle/caudal (7) part of the tongue (two not recorded). Metastatic disease was diagnosed in 12 cases. The median survival time for all tumour types was 376 days. Dogs with malignant melanoma lived significantly longer than dogs with all other tumour types. The presence of metastatic disease and tumours in the caudal tongue resulted in significantly shorter survival times. Conclusions: Dogs with lingual neoplasia live for approximately 1 year after diagnosis when undergoing surgical excision; however, metastatic disease, tumours other than malignant melanoma, and tumours affecting the caudal third of the tongue decrease survival times.

Abstract

Introduction: Lingual neoplasia uncommonly affects dogs, yet the morbidity associated with these tumours is high. Surgical excision is often the treatment of choice, but outcomes after tumour resection are rarely reported. The purpose of this study was to describe the signalment, tumour type, tumour location and outcome in a cohort of dogs undergoing resection of lingual neoplasia. Methods: This study was performed multi-institutionally utilizing the combined caseload of VSSO members. Medical records of dogs diagnosed with lingual neoplasia were reviewed and variables recorded included signalment, tumour type and location, and outcome. Statistical analysis of the recorded variables was performed. Results: Fifty-two dogs were included (23 males, 29 females). Tumour types were primarily squamous cell carcinoma (n = 19) and malignant melanoma (13); however, 20 cases of 11 other tumour types were also noted. Tumours were found in the cranial (n = 12), middle (17), caudal (7), cranial/middle (7) and middle/caudal (7) part of the tongue (two not recorded). Metastatic disease was diagnosed in 12 cases. The median survival time for all tumour types was 376 days. Dogs with malignant melanoma lived significantly longer than dogs with all other tumour types. The presence of metastatic disease and tumours in the caudal tongue resulted in significantly shorter survival times. Conclusions: Dogs with lingual neoplasia live for approximately 1 year after diagnosis when undergoing surgical excision; however, metastatic disease, tumours other than malignant melanoma, and tumours affecting the caudal third of the tongue decrease survival times.
