What is Frailty in Prostate Cancer Patients and Why is it Important?

Frailty is a complex condition characterised by a decline in physical, psychological, and social functions. In prostate cancer patients, particularly those receiving androgen deprivation therapy (ADT), frailty becomes a significant concern. ADT, along with other treatments like surgery and radiotherapy, can exacerbate frailty, particularly in older patients or those with advanced disease.

Key Symptoms of Frailty in Prostate Cancer: What to Watch For

Frailty manifests through various symptoms, including:

  • Weakness: Reduced muscle strength and grip.
  • Slowness: Decreased walking speed.
  • Exhaustion: Persistent tiredness.
  • Low Physical Activity: Decreased engagement in daily activities.
  • Unintentional Weight Loss: Significant loss of weight without trying.
  • Cognitive Decline: Difficulty with memory, attention, and decision-making.

Why Are Prostate Cancer Patients More Vulnerable to Frailty?

Androgen Deprivation Therapy (ADT) and Frailty: Understanding the Link

ADT lowers testosterone levels to slow down or stop the growth of prostate cancer. However, this reduction in testosterone can lead to muscle loss, decreased bone density, and increased fatigue—all contributing factors to frailty.

Impact of Surgery and Radiotherapy on Frailty in Prostate Cancer Patients

Surgery, including robot-assisted radical prostatectomy (RARP), is a common treatment for localised prostate cancer. However, research indicates that frailty is a significant concern for patients undergoing surgery. Frail patients are at higher risk of postoperative complications, extended hospital stays, and delayed recovery. The physical stress of surgery can worsen frailty, especially in patients who were already vulnerable before the procedure. Postoperative reduced mobility and physical function can further deteriorate overall health, making preoperative frailty assessments and tailored interventions essential.

Radiotherapy is another standard treatment for prostate cancer, often used in combination with ADT. The combination of radiotherapy and ADT significantly increases the risk of developing frailty. This treatment can lead to a decline in physical strength, bone density, and energy levels, with chronic fatigue and muscle loss being common. These effects are particularly severe in older patients or those already experiencing frailty, highlighting the importance of careful management to prevent further health decline.

How Metastases Increase Frailty Risk in Prostate Cancer Patients

Patients with metastatic prostate cancer are at a higher risk of frailty due to the advanced nature of their disease and treatment involves androgen deprevation as mainstay. Metastases often cause pain, reduced mobility, and weight loss, all of which contribute to the frailty phenotype. The systemic effects of metastases, combined with aggressive treatments, can lead to rapid physical decline.

Cognitive Decline in Prostate Cancer Patients: A Key Component of Frailty

Frailty is not only a physical condition but also has significant cognitive aspects. Patients with prostate cancer, particularly those undergoing ADT or experiencing advanced disease, may face cognitive decline. This includes issues with memory, attention, and executive function, making it harder for patients to manage their daily activities and adhere to treatment regimens. Cognitive frailty increases vulnerability to other health complications and can significantly impact a patient's overall quality of life.

How to Diagnose Frailty in Prostate Cancer Patients: Key Tests and Indicators

The Fried Frailty Phenotype: A Standard Tool for Diagnosis

One common method to diagnose frailty is the Fried Frailty Phenotype, which assesses five criteria:

  • Unintentional weight loss
  • Exhaustion
  • Weakness (measured by grip strength)
  • Slow walking speed
  • Low physical activity

Inflammatory Markers and Frailty: Understanding the Connection

Research shows that certain blood markers, such as C-reactive protein (CRP) and interleukin-6 (IL-6), are associated with higher levels of frailty. These markers indicate inflammation, which is often elevated in frail individuals.

Effective Management of Frailty in Prostate Cancer Patients

Can Frailty Be Reversed or Improved in Prostate Cancer Patients?

Interventions to manage frailty in prostate cancer patients are vital. Nutritional coaching, supervised exercise, geriatric input, frailty specialist and psychological counselling might help, the evidence is mixed. For instance, high-dose vitamin D supplementation has shown promise in reducing frailty, but not all interventions are equally effective.

Long-Term Impact of Frailty on Prostate Cancer Patients: Quality of Life, Cognitive Function, and Survival

How Frailty Affects Quality of Life and Survival in Prostate Cancer Patients

Frailty can lead to a lower quality of life, increased risk of falls and fractures, higher chances of hospitalisation, and cognitive decline. It is also associated with a shorter survival rate in prostate cancer patients, making early intervention critical.

Practical Strategies to Reduce Frailty Risk in Prostate Cancer Patients

Patients can reduce their risk of frailty by staying active, maintaining a balanced diet, and engaging in regular strength training exercises. Monitoring bone density, managing cognitive health, and taking steps to prevent falls are also important.
