Understanding Carcinoid Cancer in Cats
Carcinoid cancer, also known as neuroendocrine tumors, is a relatively rare form of cancer that can affect cats. These tumors can develop in various regions of the body, including the digestive tract, liver, heart, and lungs (VCA Hospitals). Carcinoid tumors in cats are typically small neuroendocrine tumors that secrete serotonin, histamine, and other peptides into the bloodstream, leading to various symptoms and tissue contractions.
Overview of Carcinoid Tumors
Carcinoid tumors are a widespread group of tumors that can occur in cats. These tumors arise from neuroendocrine cells and can produce biogenic amines and peptides, leading to endocrine malfunctions. In cats, carcinoid tumors are commonly found in the stomach, small intestine, liver, and heart. While they are generally small in size, they can cause significant health issues due to the substances they secrete into the bloodstream.
Signs and Symptoms of Carcinoid Cancer
The signs and symptoms of carcinoid cancer in cats can vary depending on the location of the tumor. General clinical symptoms of carcinoid tumors include anorexia, vomiting, weight loss, dyschezia (difficulty or pain during bowel movements), and manifestations of liver failure or heart disease. Carcinoid tumors in the intestine can cause symptoms similar to gastrinomas and may even lead to intestinal obstruction as they grow larger (VCA Hospitals).
Early detection and diagnosis are crucial for effective treatment. If you notice any abnormal signs or symptoms in your cat, such as persistent vomiting, weight loss, or changes in bowel movements, it’s important to consult with a veterinarian for a thorough examination and appropriate diagnostic procedures.

Specific Types of Carcinoid Cancer
Carcinoid cancer in cats can manifest in various forms, affecting different areas of the body. In this section, we will explore two specific types of carcinoid cancer that can occur in cats: Merkel cell carcinomas and neuroendocrine tumors.
Merkel Cell Carcinomas in Cats
Merkel cell carcinomas are a type of skin tumor that can develop in cats. These tumors are typically found on the head, neck, or limbs of the cat. Surgery is often the primary treatment for Merkel cell carcinomas in cats, involving the removal of the skin tumor. In some cases, additional treatment such as chemotherapy or radiation therapy may be recommended by veterinarians to further manage the cancer (VCA Hospitals).
Neuroendocrine Tumors in Cats
Neuroendocrine tumors, another form of carcinoid cancer, can occur in various regions of the body in cats. These tumors can develop in the digestive tract, liver, heart, or lungs. Due to the rarity of neuroendocrine tumors in cats, it is important to seek specialized care if suspected or diagnosed. Veterinarians may refer the case to a veterinary oncologist for further evaluation and treatment.
The treatment approach for neuroendocrine tumors in cats depends on the location and extent of the tumor. Surgical removal of the tumor may be possible, followed by additional treatment options such as chemotherapy or radiation therapy to target any remaining cancer cells.
By understanding the specific types of carcinoid cancer that can affect cats, pet owners can be more vigilant in monitoring their cats’ health. Regular veterinary check-ups are essential for early detection and prompt treatment of any potential cancerous growths. If you notice any concerning symptoms or changes in your cat’s behavior, it is important to consult with a veterinarian for a thorough evaluation.
Rare Cases and Prognosis
While carcinoid cancer in cats is relatively uncommon, there are some rare cases that have been documented in the literature. Two specific types of carcinoid cancer that are rarely seen in cats are hepatic neuroendocrine carcinomas and gallbladder carcinoids.
Hepatic Neuroendocrine Carcinomas
Hepatic neuroendocrine carcinomas are extremely rare in cats, with only a few case reports documented in the literature. These tumors arise from neuroendocrine cells in the liver and can have varying clinical presentations.
A case study described a 5-year-old castrated Japanese domestic cat with hepatic neuroendocrine carcinoma that was immunopositive for chromogranin A and gastrin. Immunohistochemical stains confirmed that most of the tumor cells were immunopositive for chromogranin A and gastrin, indicating their neuroendocrine origin. The text also highlights the possibility of a functional tumor in the cat resembling Zollinger-Ellison syndrome, caused by gastrin-producing cells.
Due to the rarity of hepatic neuroendocrine carcinomas in cats, the prognosis and optimal treatment approach are not well established. Detailed histological and immunohistochemical examinations are essential for the definitive diagnosis of hepatic neuroendocrine carcinoma in cats. If you suspect any issues with your cat’s liver or notice abnormal behavior, it’s important to consult with a veterinarian for a proper diagnosis and guidance on the best course of action.
Gallbladder Carcinoids in Cats
Carcinoid tumors originating in the gallbladder are also rare occurrences in cats. These tumors are typically slow-growing and may not cause noticeable symptoms until they reach an advanced stage.
Gallbladder carcinoids in cats are challenging to diagnose, and often the tumor is discovered incidentally during surgery or necropsy. The prognosis for gallbladder carcinoids depends on various factors, such as the extent of the tumor and whether it has metastasized to other organs. Treatment options may include surgical removal of the tumor and supportive care, but the overall prognosis can be guarded.
It’s important to note that while rare, hepatic neuroendocrine carcinomas and gallbladder carcinoids can occur in cats. Regular veterinary check-ups play a vital role in detecting any abnormalities or potential health issues early on.
