Re-irradiation for pelvic recurrences of gynecological cancers

Phase II Clinical Study on the Re-irradiation of Lateral Pelvic Recurrences of Gynecological Malignancies

Not applicable Interventional CNAO National Center of Oncological Hadrontherapy · NCT05457595

This study is testing if a special type of radiation therapy can help people with recurring gynecological cancers in the pelvis who have already had radiation treatment before.

What this trial studies

This study evaluates the effectiveness of carbon ion radiation therapy (CIRT) in treating patients with lateral pelvic recurrences of gynecological malignancies that have previously undergone radiation. The primary aim is to assess clinical response rates, while secondary aims include analyzing the safety profile of CIRT and its impact on patient survival. Patients eligible for this study must have specific criteria, including prior radiation therapy and the ability to undergo necessary imaging. The study is conducted at the CNAO National Center of Oncological Hadrontherapy in Pavia, Italy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a history of pelvic and groin recurrence of gynecological malignancies who are not suitable for radical surgery.

Not a fit: Patients with conditions that prevent adequate imaging or those with distant progression of cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide improved local control and survival rates for patients with recurrent gynecological cancers.

How similar studies have performed: Other studies utilizing carbon ion therapy have shown promising results, indicating potential for success in this novel approach.
