Introduction

Cancer treatment has evolved significantly over the last several decades, with an increasing emphasis on precision medicine, targeted therapies, and immunotherapy. However, despite the advancements in these areas, radiation therapy remains one of the cornerstones of cancer treatment, particularly when used in combination with other treatment modalities. Radiation therapy is often employed as part of a comprehensive treatment plan to enhance therapeutic outcomes, reduce recurrence, and improve survival rates. In this article, we will explore the role of radiation therapy in combined cancer treatment plans, its mechanisms of action, and its synergy with other therapies such as surgery, chemotherapy, and immunotherapy [1].

Radiation therapy, also known as radiotherapy, involves the use of high-energy radiation to target and kill cancer cells. The radiation works by damaging the DNA of the tumor cells, either directly or through the generation of free radicals. This damage prevents cancer cells from replicating and triggers their death. Since cancer cells are often more sensitive to radiation than normal cells, radiation can be highly effective in shrinking tumors or eliminating remaining cancerous tissue after surgery [2].

Radiation therapy can be delivered in different forms, the most common being external beam radiation, where focused beams of radiation are directed at the tumor from outside the body, and internal radiation (also known as brachytherapy), where radioactive sources are placed inside or near the tumor. Radiation can also be delivered using proton therapy, which uses protons instead of X-rays to treat the tumor more precisely [3].

Radiation therapy works by inducing DNA damage in cancer cells, which leads to their death either by direct damage or by triggering cellular pathways that activate apoptosis (programmed cell death). Tumor cells, which are often rapidly dividing, are particularly vulnerable to radiation. Normal cells can repair some of the damage caused by radiation, but cancer cells typically have defects in their repair mechanisms, making them less able to recover [4].

Radiation therapy is particularly effective when cancer cells are actively dividing, and tumors that are well-oxygenated (having a good blood supply) tend to be more sensitive to radiation. On the other hand, tumors with low oxygen levels (hypoxic tumors) are more resistant to radiation, a factor that clinicians must consider when planning treatment [5].

Radiation therapy is rarely used in isolation, particularly for cancers that are more advanced or difficult to treat. It is often integrated into a broader treatment plan that includes surgery, chemotherapy, targeted therapies, and immunotherapy. The combination of radiation with other treatment modalities is aimed at maximizing tumor destruction while minimizing side effects. Let's explore some of the common combinations of radiation therapy and other treatments [6].

Surgery is often the first line of treatment for localized tumors, particularly when the cancer is confined to a specific area. However, surgery may not always be able to remove the entire tumor, especially if it has spread or is located near critical structures. In such cases, radiation therapy is used in combination with surgery to improve outcomes [7].

Radiation may be administered before surgery (called neoadjuvant therapy) to shrink the tumor, making it easier to remove and increasing the likelihood of a complete resection. In some cases, radiation is used after surgery (known as adjuvant therapy) to eliminate any remaining cancer cells that may have been left behind, reducing the risk of recurrence. For example, radiation therapy is commonly used after the surgical removal of breast cancer or brain tumors to address any residual disease [8].

Chemotherapy and radiation therapy are two of the most commonly used treatments for cancer, and their combination is often referred to as chemoradiation. This combination approach is particularly useful for cancers that are difficult to treat with one modality alone, such as esophageal cancer, head and neck cancers, and non-small cell lung cancer [9].

Chemotherapy works by killing rapidly dividing cells, and when used alongside radiation therapy, it can enhance the effectiveness of radiation. The chemotherapy drugs may make tumor cells more sensitive to radiation, increase the damage caused by radiation, and help overcome radiation resistance. This combination is especially useful for treating larger tumors or tumors that have already spread to nearby tissues or lymph nodes [10].

Conclusion

Radiation therapy remains a critical component of many cancer treatment plans, and when combined with other therapies such as surgery, chemotherapy, targeted therapies, and immunotherapy, it can significantly improve treatment outcomes. By targeting tumors with a multifaceted approach, clinicians can enhance tumor control, reduce the risk of recurrence, and improve survival rates. While challenges remain, ongoing research and advances in radiation delivery techniques offer hope for more effective and personalized cancer treatments in the future. As part of a comprehensive treatment plan, radiation therapy continues to play a pivotal role in the fight against cancer.
