Preparing for Vet Appointments After a Suspected or Confirmed HCC Diagnosis

This page is meant to help you prepare for veterinary appointments after HCC is suspected or diagnosed, when testing, treatment options, and next steps may involve uncertainty. The goal is to help you understand the purpose of different steps and prepare for informed conversations with your veterinary team.

If you are still learning about canine hepatocellular carcinoma itself, you may find it helpful to start with our overview on Understanding Canine Hepatocellular Carcinoma.

When HCC Is Suspected or Diagnosed, Appointments Change

After a liver mass is discovered or HCC becomes a possibility, veterinary care may involve additional testing, follow-up appointments, or consultations with specialists. Different appointments may be intended to answer different questions or help guide different parts of care.

At this stage, it's helpful to understand:

• What information each appointment is meant to provide
• What questions may be helpful before deciding on a next step
• How the results or recommendations may affect what happens next
• How each decision might affect quality of life, both now and later

Recommendations may also change as new information becomes available.

Understanding What Diagnostic Steps Can and Cannot Tell You

Ultrasound and Imaging

Ultrasound can reveal liver masses, but imaging alone cannot determine whether a mass is benign or malignant, or identify the specific tumor type.^{Burti et al.; Leela-Arporn et al.} For a dog with a liver mass identified on ultrasound, this means that the imaging findings may raise concern but cannot by themselves establish whether the mass is HCC, another type of cancer, or a benign lesion.

Before imaging appointments, it can be helpful to ask:

• What questions is this imaging meant to answer?
• What information will it not be able to provide?
• How might the findings change recommendations, or not change them?

Fine-Needle Aspiration (FNA) and Liver Biopsy

A fine-needle aspiration (FNA) with cytology and a liver biopsy with histopathology are different diagnostic approaches.

An FNA collects cells for cytologic evaluation and can provide useful information, but it may not provide a definitive diagnosis. A liver biopsy collects tissue for histopathologic examination, which allows tissue architecture to be evaluated and can provide information that cytology alone cannot.^{Center, Liver Cytology; Center, Liver Biopsy; Weir and Stoewen; Whitbread et al.}

Preparing for Surgery Consultations

Surgery consultations may include discussion of whether a liver mass appears surgically removable and what factors may affect the procedure. The location of a liver mass and its relationship to nearby structures can affect surgical risk^{Liptak et al.; Moyer et al.} and can therefore be important considerations when surgical options and risks are evaluated.

Before surgery, it can be helpful to ask:

• How does the location of the mass affect surgical options and risks?
• What complications are possible during or after surgery?
• What circumstances could arise once surgery begins?
• If the mass cannot be safely removed, what might happen instead?
• Are there decisions that should be made in advance about what should happen if different circumstances arise during surgery?
• What should I expect during recovery and post-operative monitoring?

Preparing for Oncology Appointments and Treatment Discussions

Oncology appointments may involve discussing different treatment approaches and what may realistically be expected from them. In veterinary cancer care, treatment places an emphasis on controlling disease while maintaining quality of life.^{UC Davis; Weir et al.} This makes the goal of a proposed treatment an important part of the discussion.

If you are still learning about treatment approaches that may be discussed for canine HCC, our Treatment Options page provides an overview.

Oncology appointments can also introduce unfamiliar terminology. Our Canine HCC Glossary can be a useful reference as new terms come up.

When discussing treatment options, it can be helpful to consider both what a treatment is intended to accomplish and what it may involve for your dog. Questions that may be helpful include:

• What is the goal of this treatment?
• What benefit might realistically be expected?
• How long is treatment expected to continue?
• What will treatment involve day to day?
• How often will veterinary visits be needed, and how long are they expected to take?
• What side effects are possible, and how are they managed?
• Are any precautions needed when handling the medication or my dog's urine, stool, or saliva?
• Will any normal activities or interactions need to change during treatment?
• How might treatment and any required precautions affect my dog's day-to-day quality of life?
• What other options are available, including monitoring or supportive care?

Monitoring and Supportive Care Over Time

Ongoing care may involve monitoring the cancer, evaluating how your dog is doing over time, and revisiting the care plan as necessary. The specific tests, monitoring schedule, and supportive care used will depend on your dog's individual circumstances and veterinary recommendations.

For an overview of tests that may be used during ongoing care, see our Tests and Monitoring in Canine HCC page.

Before follow-up appointments, it can be helpful to write down current medications and supplements, changes you have observed at home, and questions that have come up since the previous visit.

Protecting Quality of Life Alongside Medical Care

Quality of life can be an important part of conversations about treatment, monitoring, and ongoing care. This can include considering not only how your dog is doing medically, but also how care decisions may affect comfort, routine, activity, and day-to-day life.

Before or during appointments, it may be helpful to consider:

• What does good quality of life look like for my dog right now?
• How might treatment, monitoring, or frequent veterinary visits affect my dog's normal routines, activities, and interactions?
• What changes should I watch for that might indicate my dog's quality of life is changing?
• What supportive care options may help maintain comfort and normal routines?

Understanding Timing and Revisiting Decisions

When discussing next steps, it can be helpful to understand whether a decision is time-sensitive and what may change if you wait. Recommendations may also change as new information becomes available or your dog's circumstances change.

Questions that may be helpful include:

• How time-sensitive is this decision?
• What might change if we wait?
• What changes or findings would prompt us to reconsider the plan?
• Can this decision be revisited as circumstances change?
