Prognosis and Patient Management

The strategy of 'watchful waiting' (or 'watch and wait') is predominantly employed for indolent lymphomas, not aggressive ones.

Answer: True

Given their slow growth rate and potential for long-term survival without intervention, indolent lymphomas are often managed with 'watchful waiting.' Aggressive lymphomas require immediate and intensive treatment.

Related Concepts:

  • What is the concept of 'watchful waiting' in the management of indolent lymphomas?: 'Watchful waiting,' sometimes referred to as 'watch and worry,' is a strategy where patients with indolent lymphomas are monitored closely without immediate treatment. This approach is chosen because the lymphomas grow slowly, and monitoring is often less harmful than early intervention.
  • What is the typical initial management strategy for many low-grade lymphomas?: For many low-grade lymphomas, which grow slowly, an initial approach of 'watchful waiting' or monitoring is often employed. This strategy involves closely observing the disease without immediate treatment, intervening only when symptoms appear or the condition progresses.

Palliative care in lymphoma management extends beyond end-of-life support to encompass symptom control and quality of life enhancement throughout the disease trajectory.
