Combination of irradiation and surgery

Area of Science:

• Oncology
• Radiation Oncology
• Surgical Oncology

Background:

• Surgery can remove macroscopic tumors, but microscopic disease may remain.
• High-dose irradiation is ineffective for large tumor volumes.
• Current treatment paradigms often consider surgery or irradiation as exclusive options.

Purpose of the Study:

• To advocate for the combined use of irradiation and surgery in cancer management.
• To challenge the traditional "either/or" approach to cancer treatment.
• To highlight the benefits of combined-modality treatment for improving patient outcomes.

Main Methods:

• Review of existing literature and clinical data on combined-modality cancer treatment.
• Analysis of treatment sequences, considering factors like tumor volume, location, and surgical extent.
• Presentation of case examples and results from various disease sites.

Main Results:

• Combined treatment can eradicate microscopic disease missed by surgery.
• Irradiation as a sole treatment is insufficient for large tumor volumes.
• The optimal sequence of surgery and irradiation is case-dependent.

Conclusions:

• The "either irradiation or surgery" concept should be abandoned.
• A conservative, combined approach enhances cure rates and quality of life.
• Preoperative irradiation is theoretically advantageous, but treatment sequencing requires careful consideration of multiple factors.
