Brief summary
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.
Detailed description
Patients with oligometastatic squamous cell carcinoma were enrolled and 2:1 randomly assigned to receive either PD-1 inhibitor +/- chemotherapy combined with local therapy (radiotherapy, surgery, radiofrequency/microwave ablation, etc.) or PD-1 inhibitor +/- chemotherapy alone. Different local therapy techniques are allowed to be used on different lesions in the same patient.All suspected malignant lesion should be included in local treatment planning in principle. The primary end point was progression-free survival (PFS). The second end points included overall survival, side effects and local control.
Interventions
1. PD-1 inhibitor +/- Chemotherapy PD-1 inhibitor: all FDA approved PD-1 inhibitor producter is suitable First line: i. TP: paclitaxel 135-175mg/m2,d1+ DDP25mg/m2, d1-3 or 75mg/m2,d1;q21d (albumin-bound paclitaxel or paclitaxel liposomes as alternative of paclitaxel permitted as alternative) or ii. PF: DDP Second line (other platinum-based agents permitted as alternative such as carboplatin, nedaplatin, oxaliplatin, lobaplatin, etc.) i. Docetaxel or ii. Irinotecan or iii. Paclitaxel (albumin-bound paclitaxel or paclitaxel liposomes as alternative of paclitaxel permitted as alternatives) 2. Local therapy i. Radiotherapy GTV=all suspected lesions. SBRT: for lung, liver, adrenal gland, celiac lymphnode metatstases 48Gy/6fx; for spine metastatic disease 30Gy/10Fx; for brain metastases 24Gy/30fx; IMRT: for bone metastatic disease 30Gy/10fx; for esophageal lesion or lesion unsuitable of SBRT 50.4Gy/28fx; ii. Surgery iii. Radiofrequency/microwave ablation
