In recent years, the incidence of multiple primary lung cancer (MPLC) has been increasing, and it cannot be ignored in clinical practice. The treatment of MPLC is still controversial, but surgical treatment is recognized as the most important treatment. However, current studies have shown that the treatment of MPLC needs to develop multimodal treatment according to different patients. This review summarizes multiple treatment method for MPLC, including surgery, ablation, chemotherapy, radiotherapy, targeted therapy, and immunotherapy in order to enhance understanding of MPLC treatment.

Objective:To explore the clinical manifestations, recurrence factors, and outcomes of revision surgery for recurrent thyroglossal duct cysts and fistulas in children. Methods:A retrospective study was conducted on the clinical manifestations, the relationship between cysts/ fistulas and residual hyoid bone of 10 patients with recurrent thyroglossal cysts and fistulas admitted to our hospital from July 2015 to July 2023, as well as the methods and effects of revision surgery. Results:The recurrence time after the initial surgery was between 7 months and 6 years, with an average of 2 years and 1 month.Clinical manifestations: 50%（5 cases） of patients have recurrent cysts near the incision, 40%（4 cases） had recurrent infections at the incision and eventually form fistulas, and 10%（1 case） experienced sleep snoring and pharyngeal trouble, were diagnosed with lingual thyroglossal duct cyst through laryngoscopy. All cysts or fistulas are connected to residual hyoid bodies, and three cases have intact hyoid bodies.Revision surgery: Nine cases underwent modified Sistrunk surgery, removing cysts, fistulas, and residual hyoid bodies. Suspension laryngoscopy and coblation were employed to treat the lingual thyroglossal duct cyst. After the revision surgery, follow-up was conducted for 8 months to 3 years, and no recurrence was found. Conclusion:All recurrences of thyroglossal duct cysts in this study were associated with residual hyoid bodies. Therefore, for thyroglossal duct cysts or fistulas, whether it is the first surgery or a revision surgery, it is recommended to choose the optimized Sistrunk operation, with the key point being complete resection of the hyoid body. Cases with lingual thyroglossal duct cyst can be treated with suspension laryngoscopy by coblation. Whether to remove the residual hyoid body requires further observation.

Objective:To explore the clinical efficacy of the coblation resection of lingual thyroglossal duct cysts under self-retaining laryngoscopy. Methods:A retrospective analysis was conducted on the clinical data of 22 patients with lingual thyroglossal duct cysts admitted to our hospital from December 2016 to December 2023. There were 16 males and 6 females, aged 2 years to 12 years and 3 months（mean: 4 years 1 month; median: 3 years 3 months）. The lingual thyroglossal duct cysts were removed by coblation under self-retaining laryngoscopy. If the cysts could not be removed completely, the epithelial cells of the remaining cysts would be ablated. Results:There were 22 cases of lingual thyroglossal duct cysts，13 cases （59.1%） of lingual thyroglossal duct cysts had laryngeal stridor and dyspnea. The postoperative follow-up period is 3 months to 7 years. 11 cases （50.0%） underwent secondary laryngoscopic evaluation.There were 4 cases of recurrence （18.2%）, with no laryngeal obstruction,bleeding, or nerve damage. Conclusion:Laryngeal stridor and dyspnea are the main clinical symptoms of lingual thyroglossal duct cysts in children. The coblation resection of lingual thyroglossal duct cysts under self-retaining laryngoscopy is safe and effective. Cyst recurrence correlates strongly with residual cyst walls, emphasizing the need for enhanced intraoperative visualization and refined surgical precision.

OBJECTIVETo investigate the role of transglutaminase 3 (TGM3) gene in laryngeal carcinogenesis.

METHODSThe authors detected the deletion indirectly through loss of heterozygosity (LOH) analysis at DNA level using 4 STR primers within and near TGM3 gene in 72 cases, and detected the differential expression of TGM3 gene in 8 cases of paired normal and cancerous tissue of laryngeal carcinoma by Northern blot.

RESULTSLOH was found existing in all of the microsatellite loci, and the LOH frequencies were 25.76%, 20.00%, 38.10% and 18.75% at D20S17, D20S607, D20S99 and D20S841 respectively; LOH concerning at least one polymorphism locus accounted for 61.11%. No correlation of clinical stage, lymph node metastasis and differentiation with the LOH of TGM3 gene was observed, P>0.05. TGM3 gene expressed significantly higher in normal tissues than in paired cancerous tissues.

CONCLUSIONTGM3 gene might play an important role in laryngeal carcinogenesis and further researches will be needed to clarify the possible mechanisms.
