RÉSUMÉ
With a deepened understanding of the pathophysiology and pathogenesis of thoracic malignancies, the treatment has been transited from traditional treatment on the basis of surgery, radiotherapy, and chemotherapy to individualized and precise targeted therapy and immunotherapy. As an antitumor immunotherapy, chimeric antigen receptor gene-modified T (CAR-T) cells have been approved by the FDA for the treatment of hematological malignancies in five CAR-T products. They have also achieved good therapeutic effects in solid tumors. However, significant challenges remain in the clinical application of CAR-T cell immunotherapy in thoracic malignancies. In this review, the latest research progress of CAR-T cell immunotherapy in the treatment of thoracic malignancies were summarized, including the basic characteristics of CAR-T cells, the popular target antigens, and the existing problems and challenges, to provide new ideas and strategies for clinical immunotherapy of thoracic malignancies.

OBJECTIVE:To observe clinical efficacy and safety of Kangfuxin liquid in the treatment of radioactive dermatitis of nasopharyngeal carcinoma patients. METHODS:A total of 73 nasopharyngeal carcinoma patients with radioactive dermatitis in the Third Affiliated Hospital of Kunming Medical University during Feb. 2016 to Feb. 2017 were divided into control group (36 cases) and observation group (37 cases) according to random number table. Both groups received routine treatment as Methylrosanilinium chloride solution,Compound cod liver oil and zinc oxide ointment for external use. Observation group was additionally given gauze soaked with Kangfuxin liquid on affected area,3 times a day on the basis of routine treatment. Both groups were treated for 4 weeks. Clinical efficacies of 2 groups were compared,and RTOG classification and dermatitis area were compared before and after treatment. The occurrence of ADR was recorded. RESULTS:There was statistical significance in the total response rate between observation group (94.6％) and control group (97.2％)(P<0.05). Before and after treatment,there were no RTOG Ⅳ patients in 2 groups. Before treatment,there was no statistical significance in the proportion of RTOG 0-Ⅲpatients or dermatitis area between 2 groups (P>0.05). After treatment,RTOG classification of observation group was improved significantly, the proportion of grade 0 patients was significantly higher than control group, that of gradeⅠpatients was significantly lower than control group,with statistical significance(P<0.05). There was no statistical significance in the proportion of RTOG 0-Ⅲpatients of control group before and after treatment(P>0.05). Two,four weeks after treatment,dermatitis areas of 2 groups were decreased significantly;dermatitis area 4 weeks after treatment was significantly smaller than 2 weeks after treatment;observation group was significantly smaller than control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Additional use of Kangfuxin liquid in the treatment of radioactive dermatitis of nasopharyngeal carcinoma patients can effectively relieve symptoms and reduce dermatitis area with good safety.

Objective To evaluate super-selective renal arterial embolization(SRAE)in treating severe renal hemorrhage when conservative treatment had failed. Methods SRAE was performed in 111 patients with severe renal hemorrhage who had failed to respond the conservative management.The clinical data,the way of embolization,the medication and the follow-up findings were retrospectively analyzed.Results Excellent results were obtained in all patients after SRAE and no serious complications occurred.The technical successful rate with single session was 95.5%(106/111).Gross hematuria disappeared within 1-4 days after the treatment.Two patients developed shock after renal embolization and had to receive surgery after the shock was controlled.Three patients had a recurrence of hematuria,the blood urine subsided after SRAE was employed again.A follow-up with a mean period of 37.4 months was carried out in 92 patients,and the follow-up checkups showed that the renal function was well preserved in all patients.Conclusion Super-selective renal artery catheterization and embolization is a safe and effective treatment for severe renal hemorrhage,it can maximally preserve the healthy renal parenchyma as well as the renal function.Therefore,this technique should be regarded as the treatment of first choice for patients with severe renal hemorrhage.
