Single vs. Multiple Fraction Trial of Stereotactic Ablative Radiotherapy for Comprehensive Treatment of Oligometastases/Progression

Stereotactic Ablative Radiotherapy (SABR) is a modern RT technique that delivers high doses of radiation to small tumor targets using highly conformal techniques, while trying to avoid healthy tissues and organs. However, SABR treatment requires increased planning, treatment time, cost and potential for higher toxicity due to the higher dose. The purpose of this study is to compare single fraction (SF) SABR vs. multiple fraction (MF) SABR in regards to toxicities, progression-free survival, quality of life (QoL), and cost-effectiveness. In a subset of patients, we will also compare patient QoL, hospitalization rates, and cost-effectiveness between patients who complete QoL questionnaires, record symptoms and receive healthcare provider-guided intervention vs. patients who complete QoL questionnaires only.

This is a phase 2 study to deliver focal radiation with pulsed systemic therapy of Abiraterone, ADT and Lynparza (olaparib) in men with castration sensitive oligometastatic prostate cancer.

Trial of Oligometastasis SBRT With Immediate, Simulation-Free Treatment Delivery (OLIGO-SWIFT)

This study is for participants whose cancer is oligometastatic, meaning it has spread to up to five spots in their body and their doctor recommends that they have stereotactic body radiation therapy (SBRT) to treat these cancer sites. SBRT is a type of radiation therapy that may help people with oligometastatic disease live longer without cancer progression. SBRT is usually given in addition to other cancer treatments, like chemotherapy, immunotherapy, or hormone therapy. Preparing for SBRT can take up to a week or longer. This can make it harder for participants to receive SBRT and coordinate care. This can also mean a longer time until symptoms from cancer sites improve. Doctors would like to treat oligometastatic cancers more quickly by reducing the time it takes to plan for the SBRT. The typical workflow for SBRT includes doctors doing a simulation which requires a CT (Computerized Tomography) scan. The CT scan is used to create a treatment plan. It can take time to schedule this CT scan and then it normally takes another 5-10 days to create a treatment plan. A way to reduce the planning time for SBRT is to use the CT scan (or other radiology scan types, like magnetic resonance imaging \[MRI\] or positron emission tomography \[PET\]) that participants had when their cancer was diagnosed to plan their SBRT. This eliminates the scheduling of an additional CT scan and the 5-10 day planning time. This is called CTsim-free (CT simulation-free) treatment planning. CT-sim-free radiation therapy planning has been shown to be effective in treating cancers that are causing pain in people with more advanced or widespread cancers. This study is being done to find out if it is safe and effective to use CTsim-free planning for SBRT to treat oligometastases.

125I Seed Implantation Plus Systemic Therapy for Oligoprogressive NSCLC or Colorectal Cancer

Most patients with metastatic cancer eventually develop resistance to systemic therapy. A subset of patients experience oligoprogression, characterized by progression at a limited number of lesions while other disease sites remain controlled by ongoing systemic therapy. This randomized phase 2 trial evaluates whether image-guided 125I seed implantation targeting all oligoprogressive extracranial lesions, combined with standard-of-care systemic therapy, improves progression-free survival compared with standard-of-care systemic therapy alone in patients with metastatic NSCLC or CRC.

Lymphocyte Support to SBRT in Patients With Oligo-metastatic Solid Cancer

The goal of this clinical trial is to assess safety of pan-metastases directed SBRT combined with ATRA and the lympho-protective efficacy of ATRA upon radiation-induced lymphopenia. This is a French bicentric, open label, phase I/II clinical study that will comprise two parts. Part I will evaluate the safety of the combination based on a single-arm safety run design, while Part II will be randomized (ratio 1:1) and will study SBRT with or without ATRA. Patients enrolled will be treated with: * SBRT to all lesions more than 1cm, on week days (from Monday to Friday), over a maximum of 2 weeks, * With or without (for part II patients randomized in the control arm) ATRA therapy: ATRA 150 mg/m\^2/day for 3 days every 3 weeks for a maximum of 4 cycles (about 3 months), starting on the first day of radiation therapy. The expected rate of patients who will have lymphopenia of grade 2 or higher in the control arm at 6 weeks post-radiotherapy is 50%. At a one-sided level of statistical significance of 0.07, the randomization of 52 patients (26 patients in each arm) will provide 85% power to detect a decrease in this rate to 15% in the SBRT+ATRA arm, using Fisher's exact test.

Niraparib Rechallenge After Surgery in Ovarian Cancer Patients With Oligometastatic Progression

The ANALLISA study is a fast, proof-of-concept, phase II clinical trial which aims to assess the efficacy of niraparib rechallenge treatment after secondary cytoreductive surgery in ovarian cancer (OC) patients with oligometastatic progression (OMP) after first maintenance therapy with any PARP inhibitor. A total of 30 patients with OC and OMP will be enrolled and will receive treatment with niraparib 300 or 200 mg, according to body weight or platelet count. Patients will start treatment within 6 weeks after surgery and will receive it until progressive disease or treatment discontinuation. The main purpose of the study is to evaluate progression-free survival (PFS) of niraparib rechallenge in OC patients with OMP and no residual disease after secondary cytoreductive surgery.

Chemoimmunotherapy Followed by Surgery for Oligometastatic Esophagogastric Cancer: (TORO Protocol)

Esophageal cancer and cancers of the gastroesophageal junction (GEJ) are among the most common malignancies worldwide. The outcome for these patients remains very poor. Patients with limited spread of their cancer (oligometastatic disease) have a better prognosis than those with widespread disease. Recent advances in treatment therapies, including use of pre-operative immunotherapy, surgery and/or targeted radiation (SBRT) may help to prolong lifespan in patients with oligometastatic disease. Patients will undergo treatment for their oligometastatic esophageal or gastric cancer with pre-operative chemoimmunotherapy followed by surgery and possibly SBRT to evaluate the value of adding surgery and possibly SBRT to their treatment.

This will be supplementing routine clinical care with the goal of improving outcomes. The treating oncologist will decide to administer standard of care systemic therapy or proceed with treatment recommended by precision medicine testing. Feasibility outcomes include the ability to have the OncoTarget and OncoTreat test performed based on tumor type and pathology, ability to procure agents, change in medication use, and identification of unknown barriers. This study is assessing the use of precision medicine in a population has documented poor outcomes with implications aimed at improving these outcomes.

Radiotherapy Combined with Systemic Therapy Versus Systemic Therapy for Oligometastatic UTUCs

This study was a prospective, open-label, phase II randomised controlled clinical study, enrolling patients with primary oligometastatic uroepithelial carcinoma, oligometastasis was defined as ≤3 organs, and the number of metastatic lesions and size of metastases were not restricted to be able to satisfy the definition of full-coverage radiotherapy, with the exception of patients with brain metastases and more than 3 liver metastases. If regional lymph node recurrence was present, all positive regional lymph nodes were collectively referred to as one lesion. Non-regional lymph node metastases were counted as the number of metastases by lymph node subregion. Patients were divided into two groups according to whether they received radiotherapy or not: 1) systemic therapy group; 2) systemic therapy + radiotherapy group. Systemic drug therapy can be chosen from chemotherapy or immune checkpoint inhibitor therapy, or combination therapy.

Stereotactic Radiotherapy for Oligometastasis (1-5) in Various Tumor Sites vs. Palliative Care

Currently, the usual standard of palliative treatment used in patients with diagnosed oligometastatic cancer in accordance with the local clinical recommendations is chemotherapy and/or a symptomatic course of radiation therapy in doses less than ablative ones The aim of the study is to increase the effectiveness of treatment of patients with tumors of various localizations with oligometastases in the bones and internal organs with the help of stereotactic radiation therapy. The method of stereotactic radiation therapy will be applied in patients with oligometastatic forms of tumors of various localizations after the current line of chemotherapy treatment T1-4, N0-3, M0-1, over 18 years of age at the start of treatment, compared with standard methods of palliative therapy in those same patient models.

Metastasis-directed Therapy for Oligorecurrent Prostate Cancer

The aim is to investigate whether the addition of short-term androgen deprivation therapy (ADT) during 1 month or short-term ADT during 6 months together with an androgen receptor targeted therapy (ARTA) to metastasis-directed therapy (MDT) significantly prolongs poly-metastatic free survival (PMFS) and/or metastatic castration-refractory prostate cancer free survival (mCRPC-FS) in patients with oligorecurrent hormone sensitive prostate cancer.

Outcomes of Local Treatment for Oligometastatic Prostate Cancer Diagnosed Using PSMA PET Imaging: OLIGOMET Study

PSMA-PET/CT or PSMA-PET/MRI are more accurate imaging modalities compared to CT/BS; in approximately 10-20% of high-risk patients diagnosed using conventional imaging PSMA-PET up-stages the disease. Therefore a substantial proportion of high-risk patients previously considered as non-metastatic are expected to be diagnosed with oligometastatic disease. While standard treatment pathways exist for patients with non-metastatic or oligometastatic disease confirmed using conventional imaging, less is known about the optimal management of patients with oligometastatic prostate cancer on PSMA-PET. Currently, data on the safety, effectiveness and oncologic outcomes of local therapies in oligometastatic patients diagnosed using PSMA-PET have been poorly reported so far. Thus, there is a need for a prospectively maintained database to collect real-world clinical data to produce high-quality research on the optimal management in oligometastatic prostate cancer who underwent PSMA-PET for primary staging and subsequent local therapy. This database will allow centers to retro- and prospectively collect data to facilitate analysis and assessment of the outcomes of oligometastatic patients managed with local therapy.

Local Therapy for Oligometastatic ESCC Patients Treated With PD-1 Inhibitor

Patients with oligometastatic squamous cell carcinoma were enrolled and randomly assigned to receive either PD-1 inhibitor +/- chemotherapy combined with local therapy or PD-1 inhibitor +/- chemotherapy alone. The primary end point was progression-free survival (PFS). The secondary end points included overall survival, side effects and local control.
