Radiotherapy in the management of lung oligometastases

Area of Science:

• Oncology
• Radiotherapy
• Medical Imaging

Background:

• Oligometastatic disease is a new clinical entity arising from advances in oncology treatments.
• Systemic therapies (targeted therapy, immunotherapy) and advanced medical imaging have reshaped cancer care.
• Lung oligometastases are common and may benefit from combined local and systemic treatment.

Approach:

• This article reviews the current state-of-the-art in radiotherapy for lung oligometastases.
• It covers pretreatment workup and defines radiotherapy regimens based on metastasis location and size.
• The review also discusses the synergistic combination of systemic medical treatments and radiotherapy.

Key Points:

• Combining radiotherapy with systemic treatment for oligometastases can prolong survival.
• Radiotherapy regimens should be tailored to the specific characteristics of lung oligometastases.
• New systemic agents necessitate careful consideration of pulmonary toxicity in treatment planning.

Conclusions:

• Radiotherapy is a viable local treatment option for lung oligometastases.
• Optimized radiotherapy regimens can be developed for lung oligometastases.
• Future research should focus on the combined use of systemic therapy and radiotherapy for improved oncologic outcomes.
