Study Groups

Tislelizumab plus chemoradiation group
In the single experimental arm, patients with nonresectable stage IIIb-IVa disease were subjected to receive neoadjuvant tislelizumab (200mg) plus chemoradiation (TP regimen plus 30Gy/12F irradiation) for conversion therapy. If conversion therapy succeeds, patients would proceed to surgery and adjuvant therapy. Otherwise, if patients were still not resectable after the conversion therapy, an additional radiation dose of 15Gy/6F would be scheduled for the ESCC lesions to achieve a definite radiotherapy dose, then, patients proceeded to consolidation therapy.
Tislelizumab
The 1st and 2nd doses were administered concurrently with TP regimen chemotherapy, 200 mg each, on D1 and D22 by intravenous infusion. In patients with successful conversion therapy, one dose of 200 mg on D60, was administered sequentially at the time before surgery after radiation therapy, and two doses of immunotherapy, on D150 and 171, were administered 8 weeks after surgery in concurrent with the 3rd and 4th cycles of chemotherapy as adjuvant therapy; in patients with failed conversion, two doses of chemotherapy combined with tislelizumab, on D60 and D81, were administered 2 weeks after the completion of radiation therapy.
Paclitaxel
A TP regimen with paclitaxel 135 mg/m\^2 + carboplatin AUC=5 was used, on D1 and D22 infused intravenously. Two cycles of adjuvant chemotherapy, on D150, 171, were started 8 weeks after surgery in patients with a successful conversion, and 2 cycles of consolidation chemotherapy, on D60, 81, were started 2 weeks after the end of radiotherapy in patients with unsuccessful conversion therapy.
Carboplatin
A TP regimen with paclitaxel 135 mg/m\^2 + carboplatin AUC=5 was used, on D1, 22 infused intravenously. Two cycles of adjuvant chemotherapy, on D150,171, were started 8 weeks after surgery in patients with a successful conversion, and 2 cycles of consolidation chemotherapy, D60,81, were started 2 weeks after the end of radiotherapy in patients with unsuccessful conversion therapy.
Radiotherapy
Radiotherapy was scheduled to be given on D1 of the 2nd cycle of chemotherapy. The primary lesions and/or lymph nodes in the operation area would be radiated in 2 stages. A dose of 30Gy/12F would be given in the first stage. When 12 Fractions were given, our MDT team would evaluate the regression of the lesions according to CT and MR results. If surgery is feasible, radiotherapy would be stopped for the primary lesions and lymph nodes in the operation area; if not resectable, the 2nd stage of radiotherapy would be given with a dose of 15Gy/6F, totaling to 45Gy/18F to the ESCC lesions. Radiotherapy for all lymph nodes outside the operation area was with DT of 45Gy/18F. All radiotherapy in this study was scheduled to be 2.5Gy/F, 1F/d, 5F/w. The preoperative radiotherapy target area was outlined by the consensus of the thoracic surgeon and radiotherapist.
