Background: About 15-20 % of patients with metastatic breast cancer (mBC) can experience oligoprogressive disease (OPD) in ≤ 5 sites of disease. Patients with OPD may benefit from metastasis-directed stereotactic radiotherapy (SBRT) to all sites of cancer progression while maintaining the same systemic treatment, aiming to prolong the time to next systemic treatment (NEST). This study aims to assess the outcomes provided by this multimodal strategy.

Malignant melanoma is third most common cause of brain metastasis after lung and breast cancer. Most patients with brain metastases from malignant melanoma are diagnosed after treatment for known extracranial metastases and have a poor outcome despite various local and systemic therapeutic approaches. Here we discuss an unusual case of a 61-year-old male patient who presented with a brain metastasis as the initial disease presentation and the presumed primary lesion was later found in the gastrointestinal tract and the scalp.

Metastasis-directed therapy (MDT) has been tested in clinical trials as a treatment option for oligorecurrent prostate cancer (PCa). However, there is an ongoing debate regarding the impact of using different imaging techniques interchangeably for defining lesions and guiding MDT within clinical trials. We retrospectively identified oligorecurrent PCa patients who had 5 or fewer nodal, bone, or visceral metastases detected by choline or prostate-specific membrane antigen (PSMA) PET/CT and who underwent MDT stereotactic body radiotherapy with or without systemic therapy in 8 tertiary-level cancer centers.

Objective: Poly (ADP-ribose) polymerase inhibitors (PARPi) have become a new standard of care for the maintenance treatment of advanced epithelial ovarian cancer. This study aims to evaluate the efficacy and safety of combining stereotactic body radiotherapy with PARPi continuation as a strategy to treat ovarian cancer oligoprogression on PARPi.
Methods: This is a multicenter retrospective study including ovarian cancer patients treated with stereotactic body radiotherapy and PARPi continuation for oligoprogression under PARPi maintenance therapy between June 2012 and May 2023 in three Italian centers.
