Factors Contributing to Postoperative Radiotherapy Delays in Head and Neck Cancer: A Comprehensive Review

Area of Science:

• Oncology
• Radiation Oncology
• Cancer Treatment

Background:

• Head and neck cancers are heterogeneous, presenting management challenges.
• Postoperative radiotherapy (PORT) is vital for reducing recurrence and improving survival in head and neck cancer.
• Delays in initiating PORT can significantly impair patient outcomes.

Purpose of the Study:

• To comprehensively review factors contributing to delays in PORT initiation for head and neck cancer.
• To examine the impact of these delays on patient outcomes.
• To discuss strategies for mitigating PORT delays and inform clinical practice and policy.

Main Methods:

• A comprehensive literature review was conducted.
• Factors contributing to PORT delays were categorized into patient-related, treatment-related, and systemic.
• Impact on outcomes and mitigation strategies were analyzed.

Main Results:

• Patient factors (health, socioeconomic, psychological), treatment factors (complications, planning), and systemic factors (resources, administration) all contribute to PORT delays.
• Delays are associated with increased recurrence risk and reduced overall survival.
• Successful interventions involve improved planning, multidisciplinary coordination, patient education, and policy changes.

Conclusions:

• Timely initiation of PORT is critical for optimal head and neck cancer treatment outcomes.
• Addressing patient, treatment, and systemic barriers is essential to mitigate delays.
• Enhanced coordination and policy adjustments are needed to ensure timely PORT delivery.
