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.
ObjectiveTo explore the clinical features, primary lesions and prognosis of optic nerve metastases.MethodsSeven patients (11 eyes) with optic nerve metastatic tumor diagnosed by the examinations of ophthalmology, laboratory and pathology in Chinese PLA General Hospital from April 2015 to September 2017 were included in this study. All patients underwent BCVA, flash VEP, OCT, orbital MRI, serum tumor marker, cerebral spinal fluid detection and PET-CT. Histopathological examination of primary or near superficial metastases was performed. The follow-up period was ranged from 16 to 44 months, with the mean of 23.0±10.9 months. The clinical characteristics, primary tumor, imaging features, treatment and clinical prognosis in the patients were analyzed.ResultsAmong 7 patients, there were 5 males and 2 females, with the mean age of 53.90±14.99 years; 3 patients with unilateral optic nerve involvement, 4 patients with bilateral optic nerve involvement; 5 patients (71.4%) first diagnosed in ophthalmology. Five patients (45.5%) were misdiagnosed as optic neuritis, optic disc edema in 6 eyes (54.5%). All of them appear loss of visual acuity, including 8 eyes (72.7%) with BCVA＜0.1, 2 eyes (18.2%) with BCVA 0.1-0.5, 1 eye (9.1%) with BCVA＞0.5. MRI results show that 1 patient with intraorbital segment, 1 patient with internal segment of optic canal, 4 patients with intracranial segment, 1 patient with intracranial segment and optic chiasma involved simultaneously, 4 patients involving surrounding tissue. There were 4 patients (57.1 %) with lung cancer, 2 patients (28.6%) with kidney cancer, 1 patient (14.3%) with gastric cance; 6 patients (85.7%) with metastasis from other sites, 2 patients with brain metastasis (1 patient with meningitis carcinomatosa). There were 2 patients (28.6%) with previous primary cancer surgery. After diagnosis, 1 patient received chemotherapy, 1 patient received radiotherapy, 5 patients gave up treatment. At the end of follow-up, 1 patient (1 eye) of chemotherapy with BCVA increased by 2 line; 1 patient (2 eyes) of radiotherapy with no change in BCVA; of the 5 patients who gave up treatment, 1 patient died of disease, 1 patient lost follow-up, and 3 patients (4 eyes) had no change in BCVA.ConclusionsWith atypically clinical manifestations, the optic nerve metastases easily misdiagnosed as optic neuritis, and with poor therapeutic effect. Primary lesions are mostly found in lung cancer.
Objective To investigate the prevalence of cognitive impairment and identify its influencing factors among lung cancer patients undergoing chemotherapy, providing a scientific basis for targeted interventions. Methods A convenience sample of lung cancer patients receiving chemotherapy at West China Hospital, Sichuan University between April and October 2024 was enrolled. Data were collected using a general information questionnaire, the Mini-Mental State Examination, Nutritional Risk Screening 2002, Hospital Anxiety and Depression Scale, Barthel index, and FRAIL scale. Univariate analyses and multivariate logistic regression were performed to determine factors associated with cognitive impairment. Results A total of 380 patients undergoing chemotherapy for lung cancer were enrolled, and 205 (53.9%) of them had cognitive impairment. Univariate analyses revealed that there were statistically significant differences between the cognitively normal group and the cognitive impairment group in age, educational level, work status, nutritional status, Barthel index, and FRAIL scale score (P<0.05). Multivariate logistic regression showed that advanced age [odds ratio (OR)=1.045, 95% confidence interval (CI) (1.015, 1.075), P=0.002] and FRAIL scale score [OR=1.369, 95%CI (1.165, 1.609), P<0.001] were identified as independent risk factors for cognitive impairment, whereas higher educational attainment served as a protective factor, compared with patients with primary school education or below, patients with junior high school, high school/secondary vocational school, college, or undergraduate education and above had a lower risk of cognitive impairment [OR=0.437, 0.258, 0.243, 0.120, P<0.05]. Conclusions Cognitive impairment is highly prevalent among lung cancer patients undergoing chemotherapy and is significantly influenced by age, educational level, and frailty. Healthcare providers should develop targeted interventions based on these factors to reduce the prevalence of cognitive impairment.
Abstract: Objective To investigate the feasibility of videoassisted thoracoscopic surgery (VATS) ronchial sleeve lobectomy for lung cancer, and to describe this treatment method. Methods Between December 2010 and April 2011, three patients in our hospital underwent VATS bronchial sleeve lobectomy as treatment for right upper lobe nonsmall cell lung cancer. The patients were one female and two males, aged 61, 65, and 62 years. Surgical incisions were the same as for singledirection VATS right upper lobectomy. The right superior pulmonary vein was firstly transected, followed by the first branch of the pulmonary artery. Then, the lung fissure was transected and the mediastinal lymph nodes, including the subcarinal nodes, were also dissected to achieve sufficient exposure of the right main bronchus. The bronchus was transected via the utility incision, and the anastomosis was accomplished by continuous suture with 30 Prolene stitches. Another 0.5 cm port in the 7th intercostal space at the posterior axillary line was added in the third operation for handling of a pair of forceps to help hold the needle during anastomosis. A sealing test was performed to confirm that there was no leakage after completion of the anastomosis, and the stoma was covered with biological material. Bronchoscopy was performed to clear airway secretions and to confirm that there was no stenosis on postoperative day (POD) 1. Results The lobectomy and lymph node dissection was finished in 5158 minutes (averaging 54.7), and the time needed foranastomosis was 4055 minutes (averaging 45.7). Total blood loss was 55230 ml (averaging 155.0 ml). Number of dissected lymph nodes was 1821 (averaging 19.3). One patient was diagnosed with adenocarcinoma of the right upper lobe with metastatic hilar lymph node invasive to the right upper lobar bronchus. The other two patients were both diagnosed with centrally located squamous cell carcinoma of the right upper lobe, and all the patients achieved microscopically negative margins. There was no stenosis of the anastomosis stoma, and the postoperative course was uneventful. These patients were discharged on POD 810 (averaging 8.7 days), and they recovered well during the followup period, which lasted 2 to 6 months. [WTHZ]Conclusion [WTBZ]For experienced skillful thoracoscopic surgeons, VATS bronchial sleeve lobectomy is safe and feasible. Making the incisions of a singledirection VATS lobectomy with an additional miniport may be an ideal approach for this procedure.
ObjectiveTo compare the cost and efficacy of ambulatory versus hospitalized surgery for lung tumor patients. MethodsTwo researchers independently conducted a computer search on February 14, 2025, in databases including CNKI (China National Knowledge Infrastructure), PubMed, Web of Science, Ovid Medline, Cochrane Library, and Wanfang Database, with the search period covering from the inception of these databases to February 2025. The outcome indicators were postoperative complication rate, length of hospital stay, and hospitalization costs. For the included randomized controlled trials and non-randomized controlled trials, we used the Cochrane risk of bias assessment tool and the Newcastle Ottawa Scale (NOS) respectively to evaluate the quality of the literature, and extracted data from the included studies for meta-analysis using RevMan 5.4 and Stata 18.0 software. ResultsA total of 12 articles were ultimately included, all of which were evaluated as high-quality, consisting of 2 randomized controlled trials, 2 prospective cohort studies, and 8 retrospective cohort studies, involving a total of 76 403 patients. Meta-analysis showed that the ambulatory surgery group had advantages over the hospitalized surgery group in terms of operation time [MD=−21.07, 95%CI (−30.55, −11.58), P<0.001], length of hospital stay [MD=−2.17, 95%CI (−3.25, −1.09), P<0.001], hospitalization costs [SMD=−1.22, 95%CI (−2.18, −0.26), P=0.01], and overall postoperative complications [OR=0.48, 95%CI (0.32, 0.74), P<0.001]. There was no statistically significant difference between the two groups in terms of postoperative hoarseness [OR=0.62, 95%CI (0.24, 1.61), P=0.33] and postoperative chylothorax [OR=0.27, 95%CI (0.07, 1.07), P=0.06]. ConclusionCompared to conventional hospitalized lung tumor resection, ambulatory lung tumor resection can significantly reduce the patient’s surgery and hospital stay time, decrease hospitalization costs, and reduce the incidence of postoperative complications. While improving hospital efficiency and reducing the economic burden on patients, it is worthy of further promotion and application.
Obstractive To observe the clinical effects and safety of endobronchial electrocautery treatment for tracheobronchial obstructive lesions in inoperable tracheobronchial squamous cell carcinoma.Methods Ninety-five patients with advanced and inoperable tracheobronchial squamous cell carcinoma were included. Thirty-four patients with central airway obstruction were treated with endobronchial electrocautery plus chemotherapy ( group A) and 61 patients without central airway obstruction were treated with chemotherapy alone ( group B) . The chemotherapy consisted of cisplatin or carboplatin, plus another thirdgeneration chemotherapy agent. Results In groug A, there were mean improvements in FEV1 of 41. 1% and in peak expiratory flow( PEF) of 65. 6% . There was no significant difference in the survival rates of the patients with and without central airway obstruction. Median survival time of group A was 11. 3 months and those of group B was 11. 6 months. 3, 6, and 12-month survival rates in group A were 87% , 68% and 39% respectively, and those in group B were 93% , 76% , and 45% respectively. Conclusion Endobronchial electrocautery is an effective and safe approach for inoperable tracheobronchial obstructive malignancies with few complications.
Objective To observe the clinical and pathological characteristics of choroidal metastatic carcinoma from lung carcinoma.Methods The clinical and pathological data of 6 patients with choroidal metastatic carcinoma from lung carcinima were analysed retrospectively.Results All the 6 patients had severe visual impairment, including 3 with severe ophthalmalgia. Flat neoplasm were seen in the posterior pole of the eyes in all the 6 patients and retinal detachment were found in 5 patients. Fundus fluorescein angiography (FFA) examination had been performed on 1 patient and blocked fluorescence and hyperfluorescence were seen in the lesion with pinpoint fluorescein leakage loop around it. CT examination had been performed on 3 patients and the shadow of flat homogenous tumor was seen. MRI examination had been performed on 1 patient and high signal intensit ies on T1W and low signal intensities on T2W were found. In all the 6 patients with primary lung carcinoma, 5 were diagnosed with adenocarcinoma and 1 with cellule carcinoma through pathological examination, and 5 patients were diagnosed with choroidal metastatic carcinoma from adenocarcinoma and 1 with choroidal metastatic carcinoma from cellule carcinoma through pathological examination.Conclusion Rapid visual acuity decrease, severe ophthalmalgia, flat neoplasm in ocular fundus and secondary retinal detachment are the main clinical characteristics of the choroidal metastatic carcinoma from lung carcinoma. Most histopathologica l manifestations of the metastatic carcinoma like that of the primary focus, and adenocarninoma is the most common histoclassification. (Chin J Ocul Fundus Dis，2003，19：333-404)
China is facing the double burden of high incidence of lung cancer and tuberculosis epidemic. Lung cancer combined with tuberculosis has a high incidence and complexity in clinical practice. High-risk groups include immunocompromised people, long-term smokers and people with a history of tuberculosis. The coexistence of the two diseases not only increases the difficulty of diagnosis and treatment decision-making, but also increases the risk of treatment-related adverse reactions and drug interactions. The guideline was developed by Committee of Integrated Rehabilitation for Lung Cancer, Chinese Anti-Cancer Association; Chinese and Western Integrated Lung Cancer Committee of Chinese Anti-Cancer Association; Society of Tuberculosis, Chinese Medical Association, aiming to standardize the diagnosis and treatment of lung cancer complicated with pulmonary tuberculosis. The guideline emphasizes the core position of combined diagnosis of multimodal imaging, etiology and pathology. It is proposed that anti-tuberculosis and anti-tumor treatment should be coordinated under the framework of multidisciplinary team, and drug interactions and timing optimization should be paid attention to. For surgical treatment, minimally invasive resection combined with systematic lymph node dissection is recommended after infection control. Systemic therapy requires individualized risk stratification and dynamic monitoring of efficacy and adverse reactions. Based on evidence-based medicine and Chinese clinical practice, combined with the accessibility of drugs and technologies, this guideline proposes a whole-process management pathway covering screening, diagnosis, treatment and follow-up, in order to improve the prognosis and quality of life of patients.
ObjectiveTo enhance the understanding of pulmonary epithelioid hemangioendothelioma (PEH), and improve the diagnostic rate of the disease. MethodsThe experience of diagnosis and treatment of a case of PEH in August 2013 was reported in the present study and the related literature was reviewed. The etiology, clinical manifestations, pathological diagnosis, differential diagnosis, therapy and prognosis of this disease were described. ResultsThe etiology of PEH remained unknown. Symptoms of PEH were usually nonspecific and mild. Chest radiograph or computed tomography usually revealed calcification in multiple nodules of half or both lungs. Primitive lumen formed by a single cell was the pathologic feature. Immunohistochemical stains showed that the malignant cells were of endothelial type. Genetic analysis was relatively limited currently. There was no effective treatment for this disease and the prognosis was poor. ConclusionPEH is a low potential malignancy occurring exclusively in young women. Symptoms of PEH are usually nonspecific and variable which can easily lead to misdiagnosis. So, pathological diagnosis should be emphasized.
