Muscle Weakness During Liver Cancer Treatment: What’s Common and How to Manage It

Yes, muscle weakness can happen during liver cancer treatment, and it has several possible causes. Muscle weakness may arise from the cancer itself, treatment side effects (especially immunotherapy combinations), nerve-related complications, inactivity, poor nutrition, or anemia. ^[1] For example, people receiving immune checkpoint inhibitors for advanced liver cancer (such as atezolizumab + bevacizumab or durvalumab + tremelimumab) are advised that muscle weakness and joint or muscle stiffness can occur and should be reported promptly. ^{[2] [3]}

Why Muscle Weakness Happens

• Cancer-related fatigue and weakness: Feeling unusually tired and weak is one of the most common effects of cancer and its treatments. ^[4]
• Immunotherapy side effects: Regimens used in advanced hepatocellular carcinoma can cause muscle or joint stiffness, muscle weakness, tiredness, and headaches; these symptoms should be communicated to your care team early. ^{[2] [3]}
• Nerve toxicity (peripheral neuropathy): Some anti-cancer drugs can irritate or damage peripheral nerves, leading to weakness, numbness, tingling, or pain; onset and severity vary by drug class. ^{[5] [6]}
• Deconditioning and inactivity: Time in treatment can reduce strength, balance, and endurance; rehab can help restore mobility. ^[7]
• Nutrition and metabolic factors: Inadequate calories and protein, or treatment‑related appetite changes, can reduce muscle mass and strength; tailored nutrition support is recommended. ^[8]
• Liver function changes: Treatment in the setting of altered liver function may increase susceptibility to side effects; clinicians adjust doses based on liver status. ^{[9] [10]}

Red Flags That Need Prompt Medical Attention

• Sudden or progressive weakness that affects walking, gripping, or daily tasks. ^[2]
• New severe headaches, confusion, or nerve symptoms (rare but can be serious in immunotherapy). ^[2]
• Signs of liver strain (dark urine, yellowing of eyes/skin, unexplained bruising or bleeding, severe abdominal pain). ^[3]
• Rapidly worsening fatigue not relieved by rest. ^[4]

If any of the above occur, contact your oncology team as soon as possible. Early reporting helps prevent complications and allows timely treatment adjustments. ^{[2] [3]}

Practical Management Strategies

1) Tell Your Care Team Early

Report muscle weakness, stiffness, or joint pain promptly; clinicians may adjust medications, check labs, or prescribe supportive treatments (e.g., pain relief or short steroid courses when appropriate). ^{[2] [3]}

2) Start Cancer Rehabilitation

• Physical therapy (PT): Builds muscle strength, balance, and safe mobility with tailored exercise plans. ^{[11] [12]}
• Occupational therapy (OT): Helps you perform daily activities (dressing, showering, cooking) more safely and with less fatigue. ^[12]
• Integrated rehab programs: Cancer rehabilitation teams support exercise and nutrition, reduce treatment-related morbidity, and help you maintain function during and after therapy. ^{[13] [14]}

3) Exercise: Gentle and Progressive

• Begin with low‑impact aerobic activity (e.g., walking) and light resistance (bands or bodyweight), guided by PT. Listen to your body and rest as needed to avoid over‑fatigue. ^{[4] [12]}
• Use energy-conservation techniques (pace activities, sit when possible, schedule breaks) to reduce strain while staying active. ^[15]

4) Optimize Nutrition and Hydration

• Aim for adequate calories and protein to support muscle rebuilding; registered dietitians can tailor plans to your treatment and appetite. ^[8]
• Address nausea or taste changes early so you can maintain intake; small, frequent meals and nutrient-dense snacks can help. ^[8]

5) Manage Pain and Stiffness

• Use doctor-directed pain relief strategies; sometimes short courses of anti-inflammatory or steroid medication are advised for treatment-related stiffness. ^{[3] [2]}
• Gentle stretching and heat/cold therapies may reduce stiffness and improve comfort. ^[12]

6) Monitor for Neuropathy

• Watch for numbness, tingling, burning, or weakness in hands/feet; report promptly as some nerve toxicities improve with dose adjustments or supportive care. ^{[6] [5]}
• PT can teach balance and safety strategies to prevent falls if sensation or strength is impaired. ^[11]

What’s the Outlook?

Many people improve with early symptom reporting, tailored rehab, and nutrition support. Rehabilitation programs for liver cancer survivorship specifically focus on restoring strength, flexibility, mobility, and endurance so you can return to valued activities. ^[7] With coordinated care, side effects can often be controlled without stopping effective therapy, though your team may modify doses or schedules based on your liver function and symptoms. ^{[10] [9]}

When to Call Immediately

• New yellowing of the eyes/skin, dark urine, severe abdominal pain, or unexplained bleeding/bruising. ^[3]
• Rapid or severe neurological changes (e.g., severe headache, confusion, profound weakness). ^[2]

Timely action helps safeguard your health and keeps treatment on track. Your care team can adjust therapy and provide supportive treatments to reduce weakness and improve function. ^{[2] [3]}
