Parallel Battles: Managing Synchronous Cervical and Triple-Negative Breast Cancers.

Multiple primary malignancies (MPMs) present diagnostic and therapeutic challenges, especially given their rarity and the distinct treatment strategies required. We report a case of a 66-year-old postmenopausal woman who presented with synchronous triple-negative breast cancer (TNBC) and cervical cancer, an uncommon and complex clinical scenario. Given the complexity of her condition, a comprehensive multidisciplinary approach was employed. The treatment strategy included neoadjuvant chemotherapy for breast cancer, followed by breast-conserving surgery and axillary lymph node dissection. Simultaneously, cervical cancer was addressed with concurrent chemoradiotherapy and brachytherapy. Remarkably, the patient demonstrated complete pathological responses in both the breast and cervical tumors following treatment. At 26 months of follow-up, she remains free of disease recurrence. This case highlights the challenges of managing synchronous TNBC and cervical cancer. It underscores the necessity for individualized treatment plans and seamless multidisciplinary collaboration to achieve optimal patient outcomes.
