Malignant pleural mesothelioma(MPM)is strongly associated with a history of asbestos exposure and is characterized by high malignancy,high mortality,and poor prognosis.Current treatments for MPM are limited and generally suboptimal,resulting in a median overall survival(OS)of approximately one year for MPM patients.However,advancements in treatment options,including surgery,radiotherapy,chemotherapy,immunotherapy and targeted therapy,have brought new hope to patients with MPM.For early-stage MPM patients categorized under the TNM staging system,surgical treatment is feasible and can improve survival rates and quality of life.However,there is still debate regarding the optimal surgical approach for MPM.In addition to surgery,radiotherapy plays a vital role in MPM treatment.It is often used as prophylactic treatment or for alleviating local symptoms in advanced stages.Radiotherapy can also serve as neoadjuvant or adjuvant therapy in surgical contexts.For patients experiencing local progression or isolated distant metastases after systemic treatment,radiotherapy is a viable option.The advent of advanced radiotherapy techniques,such as intensity-modulated radiotherapy(IMRT)and volumetric intensity-modulated arc therapy(VMAT),has significantly improved the precision and efficacy of radiotherapy while minimizing damage to healthy tissues.Furthermore,brachytherapy can relieve pain or act as a localized supplemental therapy.Chemotherapy remains the standard treatment for MPM.The combination of pemetrexed and platinum-based drugs is widely applied as first-line therapy and has been shown to significantly extend survival.However,commonly used second-line regimens often yield suboptimal results.In recent years,immunotherapy has developed rapidly.Dual immunotherapy with nivolumab and ipilimumab has demonstrated impressive clinical efficacy and safety.The combination of immunotherapy and chemotherapy has also notably extended patients'median survival.Multiple clinical trials have confirmed that this combination therapy benefits patients.Currently available targeted therapies for MPM primarily focus on anti-angiogenesis.Bevacizumab combined with chemotherapy has established its position as a first-line treatment.Research on ramucirumab and apatinib suggests that these drugs have certain efficacy and safety profiles.Beyond conventional treatment options,the UV1 cancer vaccine combined with dual immunotherapy offers new hope for patients.Chimeric antigen receptor T(CAR-T)cell therapy is an emerging treatment method being investigated in MPM patients,with phase Ⅰ clinical trials demonstrating good antitumor effects.Additionally,some antibody-drug conjugates are becoming therapeutic options for MPM through precise targeting.Tumor treating fields combined with chemotherapy has also shown efficacy in extending survival.Despite the increasing variety of treatment options for MPM,its diagnosis and treatment still face numerous challenges,including difficulties in early detection,treatment resistance,and a lack of large-scale evidence-based clinical studies.Future research should focus on improving early diagnosis rates,developing new treatment strategies,overcoming resistance,and advancing personalized therapy.Strengthening the integration of basic research and clinical trials will also be essential.Through multidisciplinary collaboration and continuous innovation,it is hoped that more effective and safer treatment options will become available,ultimately improving the prognosis of MPM patients.

Objective: To evaluate the value of multi-detector CT (MDCT) upper airway imaging in the diagnosis of obstructive sleep apnea hypopnea syndrome ( OSAHS) and in determining the location of upper airway obstruction． Methods : MDCT was used to scan the upper airways of 85 clinically confirmed adult patients with different degrees of OSAHS (73 males and 12 females) in calm breathing phase and forced inhalation phase and 60 normal adults (50 males and 10 females) in calm breathing phase to obtain nasal cavity，nasopharynx，palatopharynx and oglosopharynx volumes．Parapharyngeal fat volume was measured in OSAHS patients and normal subjects．In addition，three groups of clinical data related to OSAHS patients were recorded，including sleep apnea hypopnea index (AHI) ，body mass index ( BMI) and lowest blood oxygen saturation ( LaSO2 ) ．Finally，the measured data and clinical data of each group were statistically analyzed. Results : The volume of nasopharynx and palatopharynx in the calm breathing group was significantly smaller than that in the control group，with statistical significance．Palatopharyngeal volume forced inspiratory phase was significantly smaller than calm breathing phase in the experimental group．The parapharyngeal fat volume in the experimental group was significantly higher than that in the control group．AHI was positively correlated with BMI and parapharyngeal fat volume．LaSO2 was negatively correlated with AHI and BMI，respectively． Conclusion MDCT upper airway imaging has good clinical application value in the diagnosis，treatment and postoperative evaluation of OSAHS disease due to the significant anatomical difference between OSAHS patients and normal subjects.

Objective:To Investigate the application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal and hypopharyngeal cancer.Methods:A total of 60 patients with laryngeal and hypopharyngeal cancer occurred serious postoperative complications, including 31 cases of severe postoperative neck infection, 8 cases of dyspnea, 5 cases of massive hemorrhage and 16 cases of seriously intractable aspiration. The tracheal cannula with inner cannula and outer cuff was immediately worn on these patients and the cuff was inflated. Different treatments were carried out according to different complications. The outer cuffs were inflated for patients with severe neck infections to prevent a large amount of neck secretions inhaled to the trachea. Patients with dyspnea immediately received ventilator-assisted ventilation. For those with massive hemorrhage on the wound, doctors should prevent bleeding and stop bleeding under general anesthesia. Patients with severely coughing should perform eating training to prevent food aspiration. The inner cannula was regularly replaced once a month for all of these patients.Results:Through targeted treatment, the complications of 60 patients with cuffed tracheostomy tube with inner cannula were effectively controlled. After dressing change, the neck wounds of 31 patients with neck infection were shrunk or healed. Finally, all of the patients were replaced with metal tracheal tubes. Eight cases with dyspnea were rescued with the symptomatic and related special treatment, and finally replace by metal tracheal tube. Five cases with massive bleeding in the neck wound were successfully rescued and replaced with metal tracheal cannula. Thirteen patients among 16 cases with intractable aspiration were removed the tracheal cannula and other 3 cases of old and severely ill were replaced with metal tracheal cannula.Conclusions:The cuffed tracheostomy tube with inner cannula is of great value in the treatment of severe postoperative complications of laryngeal or hypopharyngeal cancer. It is strongly recommended that the operators should fully understand and use it reasonably after the operation of laryngeal or hypopharyngeal cancer.

Objective: To investigate the clinical efficacy of preoperative-, postoperative-radiotherapy and surgery for preserving laryngeal function in patient over 70 years of age with medial wall pyriform sinus cancer. Methods: Clinical data of 48 patients over 70 years of age with medial wall pyriform sinus cancer who received surgical treatment from January 2001 to December 2010 were retrospectively analyzed. Among them, 21 cases were given preoperative radiotherapy and surgery (R+ S). The radiation therapy dose was 45 Gy. And 14 cases′ larynx is preserved. In addition, 27 cases were given postoperative radiotherapy and surgery (S+ R). The radiation therapy dose was 65 Gy. And 10 cases had preserved laryngeal function. Survival rates were analyzed by the Kaplan-Meier method. Chi-square test was used to compare complications between two groups. Results: The larynx preservation rate in R+ S group [66.7% (14/21)] was significantly higher than that in S+ R group [37.0% (10/27), P<0.05]. The complication rate and decannulation rate in R+ S group were 42.9% (9/21) and 64.3% (9/14), respectively, showing no difference compared with those in S+ R group [37.0% (10/27) and 50.0% (5/10), respectively] (all P>0.05). The complication rates of patients with and without larynx preservation were 41.7% (10/24) and 37.5% (9/24), respectively, showing no difference between two groups (P>0.05). The overall 3-years and 5-years survival rates for all patients were 54.2% (26/48) and 35.4% (17/48), respectively. There was no significant difference in survival rates between R+ S [38.1% (8/21)] group and S+ R group [33.3% (9/27), P>0.05)]. In the R+ S group, the survival rates in patients with and without larynx preservation were 40.0% (4/10) and 29.4% (5/17), respectively, showing no significant difference between two groups (P>0.05). Conclusions It is secure and effective to choose the operation with laryngeal preservation for patient over 70 years of age with medial wall pyriform sinus cancer based on their physical conditions and the tumor extension. The preoperative- and postoperative-radiotherapy have the similar effect. Preoperative radiotherapy and surgery increases the laryngeal preservation rate.

Objective To investigate the safe and effective method for laryngeal microsurgery in difficult la‐ryngeal exposure cases .Methods We selected 62 patients’ clinical data who had received laryngeal microsurgery with difficult laryngeal exposure and could not exposure by normal self -retaining laryngoscope between July 2012 and June 2015 .There were 42 cases of vocal cord polyp ,9 cases of the vocal cyst ,5 cases of the vocal amyloidosis , 4 cases of severe atypical hyperplasia of vocal cords and 2 cases of vocal cord high differentiated squamous carcino‐ma .We completed all kinds of laryngeal microsurgery to expose the glottis by adjusting the postures of patients ,in‐creasing the anesthesia depth ,using self -retaining laryngoscope with endoscopy which can be adjusted and pressing the throat .Results In 62 patients ,58 patients were successfully operated with adjustable self -retaining laryngo‐scope with endoscopy ,the success rate was 93 .55% .And 25 cases was exposed the glottis completely by increasing the anesthesia depth ,however ,when we increased the anesthesia depth ,there were 10 cases needed to combined with pressing the throat to expose .Five patients had retropharyngeal injure with different levels .One case with small jaw deformity of the vocal cord polyp surgery was not successful ,the success of electronic endoscopic under surface anesthesia surgery .The other one case with teeth unkempt and porcelain teeth and two cases of intraoperative frozen tip vocal cord cancer completed the operation of the open throat under the non trachea incision .Conclusion Most of difficult exposed laryngeal can be safely and effectively exposed through using the adjustable self -retaining laryngo‐scope with endoscopy while normal self -retaining laryngoscope can not .When necessary ,we can put 30°endoscope into the side channel of self -retaining laryngoscope to complete all kinds of laryngeal microsurgery .

OBJECTIVE: To study the effectiveness of preserving laryngeal function for senile hypopharyngeal cancer patientsolder than 65. METHOD: The clinical data of 58 surgery cases of senile hypopharyngeal cancer patients more than 65 years old were colleted and analyzed. Thirty-one cases preserved the laryngeal function, while the rest did not. Perfect preoperative preparation was done before surgery. Surgical resection specimens were sent to frozen-section examination. When the negative incisal margin was confirmed, the defect was repaired by the appilication of local stitching, ribbon muscle flap, major myocutaneous flaps, split thickness skin and replacement of esophagus by stomach. Radical radiotherapy was used after surgery. Survival rate was calculated by the Kaplan-Meier method. Chi-square test was used to compare complications of the two groups. RESULT: The 3 years and 5 years survival rate for all cases were 48.3% (28/58) and 27.6% (16/58), respectively. For patients with laryngeal function preservation, the 3 years and 5 years survival rate were 51.6% (16/31), 29.0% (9/31), respectively. For cases without laryngeal function preservation, the 3 years survival rate and 5 years survival rate were 44.4% (12/ 27), 25.9% (7/27), respectively. The result showed no obvious difference in survival rate between two groups (P > 0.05). Surgery complication rate were 45.2% (14/31) and 40.7% (11/27), without obvious differences between the two groups (P > 0.05). CONCLUSION It is feasible for senile hypopharyngeal cancer patients to choose suitable operation based on their physical conditions and the tumor extension. The key issues include well perioperative treatment management, correct indications grasp, and intraoperative repair skills improvement.
