Partial response of metastatic cardia neuroendocrine carcinoma with the combined therapy involving PD-1 blockade after failed multi-line chemotherapies: a case report and literature review

This article reported a case that a 68-year-old man presented with belching without obvious reasons who was diagnosed with refractory cardia NEC by gastroscopy and pathological results. After failure of multi-line therapy including etoposide plus cisplatin as the first-line therapy, surufatinib plus toripalimab as the second-line therapy, FOLFIRI combined with bevacizumab as the third-line therapy, he received three cycles of albumin paclitaxel plus carboplatin combined with sintilimab as the fourth-line therapy and still obtained partial response of good efficiency. After the patient received this treatment regimen, the symptoms of dysphagia disappeared and the change trends of neuron-specific enolase were decreased. The computed tomography (CT) examination after three cycles of treatment was performed to show that the measured lesions have shrunk by more than 30% compared to the baseline CT. Additionally, there were no other adverse events such as nausea, vomiting, and diarrhea, except for grade III bone marrow suppression. At present, the patient is still being treated. This is the first case report that the albumin paclitaxel plus carboplatin combined with sintilimab has achieved good efficacy after failure of multi-line treatment of cardia NEC. It is very necessary to further explore the effectiveness and safety of this regimen in the treatment of NEC.
