S-1 plus apatinib followed by salvage esophagectomy for irinotecan-refractory small cell carcinoma of the esophagus: A case report and review of the literature.
Ontology highlight
ABSTRACT: RATIONALE:Small cell carcinoma of the esophagus (SCCE) is an uncommon but lethal disease characterized by dismal prognosis. Only 10% of advanced SCCE patients survive longer than 1 year. Resection is a choice for limited-stage cases, whereas the optimal treatment regimen for primary SCCE is yet to be elucidated. To the best of our knowledge, the efficacy of S-1 plus apatinib for irinotecan-refractory SCCE has not been reported before. PATIENT CONCERNS:A 61-year old, previously healthy male was admitted for dysphagia and fatigue. Endoscopic biopsy revealed a tumor in the middle third of the esophagus. Further exams including abdomen computed tomography excluded distant metastasis. DIAGNOSES:Primary SCCE (pT1bN1M0, IIB) was established after salvage operation. INTERVENTIONS:The tumor was enlarged after 1 cycle of first-line chemotherapy using irinotecan plus cisplatin, which indicated drug resistance. Second-line oral apatinib (425?mg daily) plus S-1 (60?mg, twice daily for 4 weeks with a 2-week drug-free interval) for a month showed efficacy, as shown by decreased serum neuron-specific enolase and stable of the esophageal lesion. Thereafter, salvage minimally invasive Ivor-Lewis esophagectomy and 2-field lymph node dissection was performed, followed by oral apatinib plus S-1 at the prior dosage for 6 months. In addition, maintenance therapy using low-dose apatinib (250?mg daily) plus S-1 (40?mg, twice daily for 4 weeks with a 2-week interval) were administered for another 6 months. Then the patient was followed up irregularly at the outpatient clinic. OUTCOMES:The adverse events including hand-foot syndrome, hypertension, vomiting, leukopenia, impaired hepatic function, and fatigue were mainly tolerable. Forty months after the operation, he was readmitted for back pain and disseminated bone metastases appeared in magnetic resonance images. His progression-free survival could not be obtained precisely, and his overall survival was longer than 40 months up to September 2019. LESSONS:S-1 plus apatinib followed by a timely esophagectomy with curative intent might be an alternative option for chemotherapy-refractory SCCE in selected patients. Better evidence is warranted.
