Background: Esophagogastric junctional squamous cell carcinoma (EJSCC) is quite rare among all gastric carcinoma, its potential resectable rate is low due to the late diagnosis. Recently, programmed death-1 (PD-1) blockade combined with anti-angiogenesis have gained accumulated clinical experiences in treating solid tumors. This is the first reported case with EJSCC who achieved a partial remission (PR) after neoadjuvant PD-1 blockade, vascular endothelial growth factor receptor 2 (VEGFR-2) inhibitor plus chemotherapy.
Case description: We present an EJSCC case treated with novel neoadjuvant treatment. A 64-year-old Chinese male had the symptom of chocking for 3 months. An enhanced abdominal computed tomography (CT) scan found a locally advanced, potentially unresectable esophagogastric junctional (EGJ) mass, and the preoperative immunohistochemistry result exhibited a highly positive programmed death-ligand 1 (PD-L1) expression, so the patient received three courses of neoadjuvant camrelizumab (200 mg/day), apatinib (750 mg/day), albumin paclitaxel (200 mg/day) and nedaplatin (70 mg/day), he was well tolerant without any adverse event, and he underwent radical surgery after a significant tumor shrinkage. The patient recovered well after surgery, and he has received four cycles of camrelizumab and apatinib as maintenance treatment. There is no recurrence 7 months after surgery.
Conclusions: PD-1 blockade, VEGFR-2 inhibitor plus chemotherapy is effective and safe for the patient with EJSCC.
