Long-term disease-free survival in three ovarian cancer patients with a single relapse

Recurrent ovarian cancer with long-term survival is uncommon and often associated with poor prognosis. We report three cases of patients with advanced ovarian cancer who have achieved long-term disease-free survival following a single prior relapse. Case 1 relapsed with a localized bulky tumor and received a complete surgical resection and chemotherapy. Case 2 had a persistent central pelvic tumor after debulking surgery and second-line chemotherapy, and yet achieved excellent control with concurrent chemoradiation to the true pelvis. Case 3 relapsed with paraaortic lymph node metastasis and probable lung metastasis (subsequently negated by positron emission tomography) and received chemotherapy alone. These three patients have since remained disease-free for 13, 12, and seven years, respectively, since their first relapse. We conclude that select patients can obtain long-term disease-free survival after the first relapse by accurate restaging and aggressive multimodality treatment.
