Liver Cancer Recurrence and Treatment Options: A Patient's Guide

Liver tumor treatment

Hello Dr.
Chen,
Last March, my family member was diagnosed with liver cancer during a health check-up.
In April of last year, they underwent surgery for resection, and the pathology report indicated stage 1 or 2.
In October of last year, a follow-up CT scan showed no recurrence, and subsequent ultrasound follow-ups also revealed no abnormalities.
The most recent ultrasound examination was in May of this year, which also showed no abnormalities.
However, during a second CT scan in July of this year, recurrence of liver cancer was detected in the S1 and S8 regions, measuring 1.4 cm and 2.4 cm, respectively.
Subsequently, TACE treatment was performed in early August.
After learning about the recurrence from the CT scan, I sought opinions from other physicians.
Some suggested laparoscopic resection, while others indicated that TACE should be done first (the physician mentioned that surgery or RFA is currently not suitable and that we should wait until after TACE).

I would like to ask Dr.
Chen:
1.
Why was the liver cancer recurrence not detected in the ultrasound in May? Was it due to the location being difficult to detect or because it was too small to be identified?
2.
After TACE treatment, how long should we wait before performing a CT or MRI to confirm the treatment's effectiveness? Is one month sufficient?
3.
Is it not possible to perform laparoscopic surgery or RFA on the liver cancer in the S1 region?
Thank you for your assistance with these questions.

Dr. Chen Shidian reply Gastroenterology and Hepatology

Hello, after the surgery, you can undergo a self-paid EOB-MRI in one month to confirm how many tumors are still viable or newly developed.
S1 electrosurgery requires experienced personnel and carries slightly higher risks.
Changhua Hospital cares about your health.

More Info

Understanding liver cancer recurrence and treatment options is crucial for patients and their families navigating this challenging diagnosis. Liver cancer, particularly hepatocellular carcinoma (HCC), can be aggressive and often recurs after initial treatment. Here, I will address your specific questions and provide additional insights into the management of liver cancer.

1. Why was the recurrence of liver cancer not detected in the May ultrasound?
The sensitivity of imaging modalities can vary significantly. Ultrasound, while a useful tool for monitoring liver conditions, may not always detect small tumors, especially if they are located in challenging areas of the liver or if they are small in size. In your case, the tumors measuring 1.4 cm and 2.4 cm may have been below the detection threshold of the ultrasound. Additionally, factors such as the operator's experience, the patient's body habitus, and the quality of the ultrasound equipment can influence the results. CT scans are generally more sensitive than ultrasounds for detecting liver lesions, particularly when they are small or located in complex anatomical regions.

2. How long after TACE treatment should a follow-up CT or MRI be performed to assess treatment effectiveness?
After Transarterial Chemoembolization (TACE), it is common practice to wait approximately 4 to 6 weeks before performing follow-up imaging studies like CT or MRI. This timeframe allows for the effects of the treatment to manifest, as the embolization process can lead to changes in the tumor's appearance over time. A one-month follow-up may be too early to accurately assess the treatment's effectiveness, as the tumor may still be undergoing necrosis or other changes. Therefore, a follow-up at the 4 to 6-week mark is generally recommended.

3. Is it possible to perform laparoscopic surgery or RFA on the S1 liver cancer?
The decision to perform laparoscopic surgery or Radiofrequency Ablation (RFA) depends on several factors, including the tumor's size, location, and the overall health of the liver. Tumors located in the S1 segment (the caudate lobe) can be particularly challenging due to their anatomical position and proximity to major blood vessels. If the tumor is small and there are no significant underlying liver conditions (like cirrhosis), RFA may be a viable option. However, if the tumor is larger or if there are concerns about the liver's functional reserve, the surgical team may recommend TACE as a first-line treatment to control the disease before considering surgical options.

Additional Insights on Liver Cancer Management
Liver cancer management is multifaceted and often requires a multidisciplinary approach. Here are some key points to consider:
- Regular Monitoring: After initial treatment, regular follow-up with imaging studies is essential to detect any recurrence early. The typical schedule may involve imaging every 3 to 6 months for the first few years post-treatment.

- Treatment Options: Besides TACE, other treatment modalities include surgical resection, liver transplantation, RFA, and systemic therapies (like targeted therapies and immunotherapy). The choice of treatment depends on the tumor's characteristics and the patient's overall health.

- Lifestyle Modifications: Patients are encouraged to adopt a healthy lifestyle, including a balanced diet, regular exercise, and avoiding alcohol, which can help support liver health and overall well-being.

- Support Systems: Emotional and psychological support is crucial for patients and their families. Engaging with support groups or counseling can provide comfort and guidance during this challenging time.

In conclusion, understanding the nuances of liver cancer recurrence and treatment options is vital for making informed decisions. It is essential to maintain open communication with your healthcare team, who can provide personalized recommendations based on your specific situation.
