目的 探讨原发性肺印戒细胞腺癌（PSRCACL）的临床病理学特点、诊断与鉴别诊断及其预后因素等。 方法 收集2000年1月－2012年6月间50例PSRCACL患者的临床资料，进行组织学及免疫组织化学检测观察，并进行随访和结合文献复习分析。 结果 PSRCACL的临床症状及影像学表现与非小细胞肺癌无明显差异，其诊断与鉴别诊断依据其特殊的细胞形态学及免疫组织化学检测。PSRCACL的发病率约占肺腺癌的1.20%，平均发病年龄为53.3岁，中位年龄为54.5岁，男女比例为1.17︰1。患者的中位生存时间约为56个月，1年生存率约为85.4%，3年生存率约为67.4%，5年生存率约为40.9%。患者的生存率与患者的性别、年龄无关（P＞0.05），与肿瘤的大小、是否伴有癌转移及TNM分期有关（P＜0.05）。 结论 PSRCACL是一种比较罕见的、好发于中青年人、恶性程度较高、易发生侵袭和转移、预后较差的恶性上皮性肿瘤，除手术治疗外，目前尚无标准化疗方案。
ObjectiveTo summarize the clinical features of pulmonary mucoepidermoid carcinoma (PMEC) and improve the level of the diagnosis and therapy.MethodsA case of PMEC was reported and related literatures were reviewed in PubMed, WanFang data and China National Knowledge Infrastructure.ResultsA 21-year-old female patient, complaining of cough and expectoration for 5 months, intermittent hemoptysis for 3 months and repeated fever more than 4 days, was hospitalized in March 2017. After admission, the patient was diagnosed as low-grade PMEC and received anti-infection, fibrobronchoscope sputum aspiration and alveolar lavage therapy. During the hospitalization, the anti-infection of the patients was not much effective, and the chest CT examination suggested space-occupying lesions in the middle lobe of the right lung. After the surgical removal of the right lung, the syndrome of the patient was improved. A total of 13 patients were reviewed, there was no obvious gender difference, and the median age was about 40 years old (most frequently occurred in younger adults with an average age less than 50 years). Frequent clinical manifestations were cough, fever and hemoptysis, which were often accompanied with atelectasis. Most of the patients could be improved after surgical resection, and a few need comprehensive treatment including radiotherapy, chemotherapy and targeted treatment, etc.ConclusionsPMEC is rare and the etiology is still unclear. The pathology is mainly low-grade. Majority of patients with PMEC could be cured after surgical resection.
The great clinical efficacy of an enhanced recovery after surgery (ERAS) program has been illustrated by the decreased incidence of perioperative complications and the shortened length of in-hospital stay. Furthermore, the ERAS programs have their own key techniques and strategies in the clinical application to the unique diseases and operative modes. The key technology of an ERAS program is the minimally invasive surgery, which has been widely utilized in the surgical specialties. The main strategy in an ERAS program consists of the intensive pulmonary rehabilitation and optimal perioperative care that aim to improve the in-hospital outcomes of lung cancer patients who are considered at high surgical risk. Pulmonary rehabilitation is regarded as the mainstay of the ERAS strategies but its clinical protocols still remain less mature. The purpose of this overview is to summarize the current pulmonary rehabilitation programs in terms of the suitable crowd, the feasible protocols and the clinical significance.
目的探讨原发性肺软骨瘤（chondroma）的临床特点、诊断及其治疗方法，以提高临床医师对本病的认识和诊疗水平 方法回顾性分析我院4例（男2例、女2例，年龄50～63岁）肺软骨瘤的临床资料，并结合国内外1983年1月至2013年9月30年文献报道的51例患者的临床资料进行分析和总结。 结果55例患者中男30例，女25例，发病年龄10～84（42.47± 17.27）岁。主要临床表现有咳嗽、咳痰、痰中带血、胸闷、胸痛、呼吸困难、喉部不适等，也有无临床症状，于体检发现。临床诊断以肺癌、结核、错构瘤、炎性假瘤、肺畸胎瘤及肺部包块等。55例患者都行手术治疗，无手术死亡。 结论肺软骨瘤是临床上一种较为罕见的良性肿瘤，临床表现缺乏特异性，术前误诊率较高，影像资料有助于诊断和鉴别诊断，确诊依靠病理诊断以及肺软骨瘤与Carney’s综合征的关系，手术切除治疗疗效确切。
ObjectiveTo explore the independent risk factors for postoperative retention of urinary catheters in the ward of lung tumor patients due to urinary retention under the concept of enhanced recovery after surgery (ERAS).MethodsSeventy-five patients with lung tumors who had urinary catheters left in the postoperative ward between June 2019 and August 2019 were selected as a case group, and 75 patients with lung tumors who did not have urinary catheters in the perioperative period as a control group. Independent risk factors for indwelling urinary catheters in the postoperative ward were screened by univariate and multiple-variate logistic stepwise regression analysis.ResultsThere were 45 males and 30 females in the case group with an average age of 55.33±10.78 years, 28 males and 47 females in the control group with an average age of 57.12±10.06 years. Univariate analysis showed that gender, operative time>2 h, intraoperative fluid volume≥1 200 mL, and fluid volume within 6 h of returning to the ward after surgery>1 200 mL were associated with the occurrence of indwelling urinary catheters in patients with lung tumors in postoperative wards (P<0.05). Multiple-variate logistic regression showed that male (OR=2.311, 95%CI 1.173-4.552, P=0.015), infusion volume within 6 h of returning to the ward after surgery>1 200 mL (OR=2.491, 95%CI 1.149-5.401, P=0.021) and intraoperative infusion volume≥1 200 mL (OR=2.105, 95%CI 1.022-4.340, P=0.044) were independent risk factors for postoperative retention of urinary catheters in patients with lung tumors.ConclusionThe occurrence of indwelling urinary catheter in lung tumor patients under the ERAS concept is the result of a combination of factors, and patients who are male, have infusion volume>1 200 mL within 6 h of returning to the ward after surgery, and have intraoperative infusion volume≥1 200mL are the high-risk group for postoperative ward indwelling urinary catheter, and health care personnel should strengthen the assessment and observation, provide targeted health education, appropriately control the perioperative fluid volume, and take other measures to reduce the occurrence of indwelling urinary catheters due to urinary retention postoperatively in ward.
Objective To explore the incidence and severity of symptoms of the lung cancer patients undergoing concurrent chemoradiation therapy, and reveal the influence of symptom clusters on the patients’ daily activities. Method From December 2016 to June 2017, a total of 150 patients with lung cancer who underwent concurrent chemoradiation therapy were investigated by using M. D. Anderson Symptom Inventory of Chinese Version and the revised lung cancer module. Results For the patients during the period of concurrent chemoradiation therapy, the symptoms with severity score >5 were fatigue, nausea, poor appetite, cough, distress, disturbed sleep, vomiting, expectoration, and grief; the symptoms with incidence >80% were fatigue, nausea, disturbed sleep, poor appetite, grief, and cough. Joy of life (87.33%), emotion (74.38%), and work (72.67%) were the top three in terms of high incidence of symptom distress. Exploratry factor analysis revealed 4 major symptom clusters, which were fatigue-related symptom cluster, gastrointestinal symptom cluster, emotion symptom cluster, and respiratory symptom cluster. Conclusions During the period of concurrent chemoradiation therapy, lung cancer patients suffer from multiple symptom clusters. Medical staff should assess symptoms timely, and provide effective interventions, to improve the patients’ quality of life.
目的：运用多层螺旋CT（MSCT）后处理技术显示周围性肺癌与支气管关系，分析其影像表现及诊断价值。方法：采用MSCT对77例周围性肺癌行层厚为0.5 mm的容积靶扫描，通过多平面或曲面重建（MPR或CMRP）以及表面遮盖（SSD）法显示支气管与周围肿块的关系,CT影像表现与手术、病理对照。结果：（1）全部3～7级支气管均全程、较完整显示。42例腺癌中与支气管有关系者为39例（92.9％），20例鳞癌中为15例（75.0％）。（2）肿瘤—支气管关系可分为4型：Ⅰ型，支气管被肿块截断；Ⅱ型，支气管进入肿块内后被截断；Ⅲ型，支气管在肿块内保持通畅；Ⅳ型，支气管紧贴肿块边缘走行，形态正常或受压移位。（3）发生率：Ⅰ型为48.1％（37/77），其中鳞癌略多于腺癌；Ⅱ型为13.0%（10/77），其中鳞癌略多于腺癌；Ⅲ型为16.9％（13/77），仅见腺癌；Ⅳ型为15.6％（12/77），腺癌略多于鳞癌。（4）与第四级支气管相关的肿块，鳞癌多于腺癌；与第六级支气管相关的肿块，腺癌多于鳞癌。结论：采用MSCT超薄层靶扫描后行MPR、CMPR和SSD重建，能准确显示肿块与支气管关系，并反映一定的病理改变关系，对良恶性鉴别或长期预后等相关性研究有着重要意义。
ObjectiveTo compare clinical results between single and double chest tube applications after lung cancer resection, and explore the role of single chest tube in postoperative fast track recovery. MethodNinety-three patients with lung cancer who underwent lobectomy between March and December of 2009 in West China Hospital of Sichuan University were included in this study. All the patients were divided into a single-tube group including 46 patients (39 males and 7 females) with their age of 58.4±9.5 years, and a double-tube group including 47 patients (32 males and 15 females) with their age of 58.2±9.0 years. Drainage amount, duration, postoperative hospital stay, and incidences of pneumothorax and pleural effusion after removal of chest tubes were compared between the 2 groups. ResultsThe percentage of patients undergoing complete video-assisted thoracic surgery (VATS) of the double-tube group was significantly higher than that of the single-tube group, and the percentage of patients undergoing thoracotomy of the double-tube group was significantly lower than that of the single-tube group (P < 0.05). Drainage amount of the double-tube group was significantly larger than that of the single-tube group (824.4±612.5 ml vs. 510.7±406.7 ml, P < 0.05). There was no statistical difference in drainage duration, postoperative hospital stay, the incidences of subcutaneous emphysema, pneumothorax, pleural effusion or re-insertion of chest drain between the 2 groups (P > 0.05). ConclusionClinical results of single chest tube is better than or equivalent to those of double chest tubes after lung cancer resection, and drainage duration of single chest tube application might be shorter.
Objective To evaluate the security and clinical value of the combination of three-dimensional computed tomography-bronchography and angiography (3D-CTBA) and indocyanine green (ICG) staining in video-assisted thoracic surgery (VATS) segmentectomy. Methods The clinical data of 125 patients who received VATS segmentectomy from January 2020 to January 2021 in our hospital were retrospectively analyzed. There were 40 (32.0%) males and 85 (68.0%) females with an average age of 54.8±11.1 years. Results The procedure was almost identical to the preoperative simulation. All intersegment planes were displayed successfully by ICG reverse staining method. There was no allergic patient. A total of 130 pathological specimens were obtained from the 125 patients. The mean operation time was 126.8±41.9 min, the time of first appearance of fluorescence was 22.7±4.9 s, the mean mark time was 65.6±20.3 s, the median blood loss was 20.0 (10.0-400.0) mL, the postoperative hospital stay was 5.6 (4.0-28.0) d, and the postoperative retention of chest tube time was 3.2 (2.0-25.0) d. Pathological results showed that microinvasive adenocarcinoma was the most common type (38.5%, 50/130), followed by invasive adenocarcinoma (36.9%, 48/130); there were 3 metastatic tumors (3/130, 2.3%).Conclusion The combination of 3D-CTBA and ICG reverse staining is proved to be a safe, necessary and feasible method. It solves the difficult work encountered in the procedure of segmentectomy, and it is worth popularizing and applying in clinic.
