What exercises are safe for a patient with a port for chemotherapy?

Exercise Safety with Chemotherapy Ports

Patients with chemotherapy ports can safely engage in regular exercise, including moderate-to-vigorous intensity aerobic activity and resistance training, without increased risk of port complications. 1

General Exercise Recommendations During Chemotherapy

Exercise is not only safe but beneficial during active cancer treatment, improving fatigue, physical function, muscle strength, and quality of life. 1 The evidence strongly supports that physical activity does not interfere with chemotherapy efficacy and may even improve treatment completion rates. 1

Starting an Exercise Program

• Begin exercise as soon as possible after diagnosis, avoiding prolonged inactivity 1
• For previously sedentary patients: Start with low-intensity activities like stretching and brief, slow walks, progressing gradually 1
• For those already exercising: Continue at potentially lower intensity or shorter duration during treatment, but maintain activity as much as possible 1
• Discuss timing with your oncology team: Some clinicians recommend waiting to assess chemotherapy side effects before starting, while others encourage immediate initiation 1

Recommended Exercise Parameters

Target at least 150 minutes per week of moderate-intensity aerobic exercise 1

Include strength training at least 2 days per week 1

• Moderate-intensity activities include brisk walking (5 km/h) and stationary cycling 1
• Resistance training is safe and effective, even heavy-load training (85-90% of 1 repetition maximum) has been studied without increased complications 2
• Combined aerobic and resistance exercise provides superior benefits for muscle strength and physical function 1

Port-Specific Safety Considerations

There are no specific restrictions on exercise type or intensity related to having a chemotherapy port. The available evidence demonstrates that ports are durable devices with low complication rates during normal use. 3, 4

What the Evidence Shows About Port Safety

• Ports can be used immediately after implantation (median 102 minutes in one study) without increased acute complications 3
• Common port complications are unrelated to exercise: infection (7.5%), drug extravasation (5.0%), thrombosis (3.3%), and catheter malposition (9.2%) 4
• No evidence suggests exercise increases port-related complications 3, 4

Practical Precautions

While exercise doesn't inherently damage ports, use common sense:

• Avoid direct trauma to the port site (e.g., contact sports, heavy weights directly over the port)
• Monitor for signs of complications: pain, swelling, redness, or warmth at the port site
• If the port is actively accessed with a needle: Secure the needle and tubing properly during movement to prevent dislodgement 5

Special Populations Requiring Modified Approach

Older adults and those with bone metastases, osteoporosis, arthritis, or peripheral neuropathy require careful attention to balance and fall prevention 1

• Consider having a caregiver or exercise professional present during sessions 1
• Progress more slowly with intensity and duration 1
• Emphasize balance training to reduce fall risk 6

During periods of bed rest: Physical therapy is advisable to maintain strength, range of motion, and counteract fatigue and depression 1

Expected Benefits

Exercise during chemotherapy provides:

• Moderate reduction in fatigue (standardized mean difference -0.52) 1
• Improved cardiorespiratory fitness (VO2max improvement, standardized mean difference 0.46) 1
• Increased muscle strength, particularly with resistance training 1
• Better physical function and quality of life 1
• Reduced anxiety and depression 1

Common Pitfalls to Avoid

• Don't assume you must be sedentary during treatment: Inactivity leads to deconditioning, muscle loss, and worsened fatigue 1
• Don't wait indefinitely to start: Early initiation prevents functional decline 1
• Don't avoid resistance training due to lymphedema fears: Heavy-load resistance exercise does not increase lymphedema risk, even in at-risk breast cancer patients 2
• Don't exercise through severe treatment side effects: Adjust intensity and duration based on how you feel, but maintain some activity 1
