Abstract:
Limited-stage small cell lung cancer(SCLC)is a highly malignant and rapidly progressing neuroendocrine tumor,while uremia is a complication of the end-stage of chronic renal failure.The patients with SCLC complicated with uremia have poor treatment tolerance,limited options for anti-tumor treatment regimens,and great difficulty in diagnosis and treatment.This study analyzed one case of a 69-year-old male patient with limited-stage SCLC complicated with uremia(with a history of regular hemodialysis,3 times per week),to discuss his first-line treatment regimen,efficacy,and the impact of hemodialysis on the plasma concentrations of the anti-tumor drugs,and reviewed the relevant literature to provide a reference for the treatment of similar patients.The patient was admitted to the hospital due to"cough and hemoptysis for half a month"and was diagnosed with limited-stage SCLC stage ⅢA(T2aN2M0)by computed tomography(CT)and lung puncture biopsy.After discussion by the multi-disciplinary treatment(MDT)team,the patient received 6 cycles of Etoposide(VP-16)+carboplatin chemotherapy combined with adebrelimab immunotherapy,followed by sequential adebrelimab maintenance therapy.The efficacy was evaluated as partial response(PR)and the response is ongoing.During the treatment,level 4 hemoglobin decrease,level 3 neutropenia,and level 2 leukopenia occurred,which were alleviated after symptomatic treatment.The blood concentration monitoring results showed that the plasma concentrations of etoposide and carboplatin increased rapidly during drug infusion,and gradually decreased after the end of infusion.Hemodialysis could rapidly reduce the plasma concentration of carboplatin,but had no significant effect on the plasma concentration of etoposide.Therefore,the immunotherapy combined with reduced-dose chemotherapy regimen is safe and effective for this type of patient.Plasma drug concentration monitoring can be used to observe drug metabolism,but the optimal monitoring time points and clinical value need further study and validation.
