Maxillectomy for the treatment of a recurrent nasal adenocarcinoma in a cat

“…A buccal mucosal flap was used to close the resulting defect. Although eating and grooming are only rarely affected after maxillectomy in cats (Martano and others 2012), due to the extent of surgical invasion in our patient, an oesophagostomy tube was placed to facilitate feeding in the early postoperative period. In cases of extensive orofacial surgery, effective perioperative analgesia is also crucial.…”

“…(Morris and Dobson 2001) Radiation therapy is considered the standard of care for control of a local disease (Martano and others 2012). Nevertheless, reports of treatment for feline non-lymphoproliferative nasosinal tumours are only few, and case numbers in studies are small (Withrow and others 2013).…”

Video‐Assisted Thoracoscopic Extirpation of the Tracheobronchial Lymph Nodes in Dogs

“…We report a minimally invasive technique for excisional biopsy of the TBLN, which could be used for evaluation of nodal metastasis in dogs with pulmonary or other intrathoracic neoplasia, and have described histologic artifacts associated with this method of biopsy in normal lymph nodes. Primary lung tumors are highly aggressive and tend to metastasize to the TBLN and other lung lobes . A very important prognostic factor in dogs with solitary lung tumors is regional lymph node involvement .…”

“…Assessment of TBLN for metastatic disease is an important predictor of outcome in dogs with primary bronchoalveolar carcinoma, but TBLN are very challenging to access for percutaneous preoperative fine needle aspiration or biopsy because of their location at the pulmonary hilus, dorsal to the heart, and intimately associated with major neurovascular structures. Because of this, it is currently recommended that when lung tumor excision is performed, as part of the surgical procedure TBLN should be palpated and biopsied if enlarged …”

Advances in Video-Assisted Thoracic Surgery, Thoracoscopy

“…21,22 Identification of surgical margins is challenging and tracheobronchial lymphadenectomy and histopathology is recommended to better assess prognosis and the need for adjunctive treatment in dogs with lung tumors. 22,24,25 Recently, near-infrared field fluorescent (NIRF) technology has been investigated for pulmonary neoplasia VATS applications experimentally. 26 NIRF allows for activation of cancer cells in tissues, such as the pleura and lung.…”
