What happened, in summary

A 50-year-old woman developed a worsening skin rash and muscle weakness over 3 months, making it difficult to lift household objects or climb stairs. Autoimmune testing did not identify a cause. Imaging then showed advanced ovarian cancer, and her CA-125 was markedly elevated at 3169. A pelvic lymph-node biopsy confirmed high-grade serous carcinoma.

She received palliative carboplatin, paclitaxel, and bevacizumab. Prednisolone was used for the associated dermatomyositis. The cancer responded so strongly that interval debulking surgery was not performed, and she continued maintenance bevacizumab with surveillance. Her muscle symptoms improved, although skin flares sometimes accompanied cancer activity.

A later CA-125 rise prompted imaging that showed small-volume nodal progression, followed 3 months later by multiple retroperitoneal nodes. Carboplatin and gemcitabine produced a partial response, but the cancer progressed again after 5 months. Liposomal doxorubicin was planned at the latest follow-up.
