Radiotherapy for ovarian cancers - redefining the role

Area of Science:

• Gynecologic Oncology
• Radiation Oncology
• Medical History

Background:

• Radiation therapy for ovarian cancer was historically abandoned due to toxicity and lack of survival benefit.
• Chemotherapy became the standard adjuvant treatment, but ovarian cancer recurrence remains high, especially in the abdomen and pelvis (approx. 70%).

Purpose of the Study:

• To review the current literature on radiation therapy for ovarian cancers.
• To redefine the role, rationale, and indications for radiotherapy in ovarian cancer management.
• To explore the impact of technological and biological advancements on radiotherapy's potential in ovarian cancer.

Main Methods:

• A comprehensive literature search of PubMed/MEDLINE was conducted.
• The search covered publications from January 1975 to March 2014.
• The review focused on studies evaluating radiation therapy in ovarian cancers.

Main Results:

• Ovarian cancer recurrence rates after first-line chemotherapy remain significant, particularly in abdominopelvic sites.
• Advances in radiation technology and a deeper understanding of ovarian cancer subtypes necessitate a re-evaluation of radiotherapy's utility.
• The review aims to establish current indications and rationale for using radiation therapy in ovarian cancers.

Conclusions:

• Despite historical limitations, modern radiation techniques may offer new possibilities in ovarian cancer treatment.
• Chemotherapy failures highlight the need to reconsider all available treatment modalities, including radiation therapy.
• A redefinition of radiotherapy's role is crucial given ongoing challenges in ovarian cancer management.
