We report a case of a young patient with hepatocellular carcinoma on hepatitis B virus related liver cirrhosis and multiple lung tuberculosis cavitations. The patient was referred to our centre for liver transplantation. We adopted a strategy with sequential treatments. First a left extra-pericardial pneumonectomy was performed without opening the infected cavern, followed by a therapy with rifampicin, isoniazid and ethambutol for a period of nine months. After the cure of tuberculosis, the monolung patient eventually was listed for liver transplantation. An accurate planning of a multistep therapeutical strategy, an appropriate anesthetic management and a meticulous surgical technique allowed to successfully transplant a young patient suffering from three life-threatening diseases: cavitary tuberculosis, hepatitis B virus cirrhosis and hepatocellular carcinoma. Thirty months after liver transplantation the patient is in good health, with normal liver function, forced expiratory volume in one second of 42% (1.53 liters) and without any tuberculosis disease reactivation.展开更多

It is composed of a mixture of carcinoma and sarcoma elements. We present a case of 64-year-old male with carcinosarcoma of the lung associated with tuberculosis involvement of the same site. The patient was admitted for cough, malaise and fever. Bronchial lavage culture revealed M. tuberculosis. Six months after completion of tuberculosis treatment, the patient was admitted for hemoptysis and headache. CT revealed a solid lesion at the left upper lobe anterior bronchus. Histopathologic examination of the bronchial biopsy specimen revealed carcinosarcoma. Cranial MRI showed a metastatic lesion in the cerebellum which was removed surgically. Four months later, the patient developed bilateral malignant pleural effusions, recurrent cerebellar and skeletal metastases and died in the intensive care unit following intubation for respiratory failure. We describe a case of pulmonary carcinosarcoma occurring at the same localization shortly after successful treatment of tuberculosis with reference to relevant literature.展开更多

文摘BACKGROUND Colorectal cancer(CRC)ranks high among the most common types of malignant tumors.The primary cause of cancer-related mortality is metastasis,with lung metastases accounting for 32.9%of all cases of metastatic CRC(MCRC).However,cases of MCRC in the lungs,which present concurrently with primary peripheral lung adenocarcinoma,are exceptionally rare.CASE SUMMARY This report describes the case of a 52-year-old female patient who,following a colonoscopy,was diagnosed with moderately differentiated adenocarcinoma based on rectal mucosal biopsy findings.A preoperative chest computed tomography scan revealed a ground-glass nodule in the right lung and a small nodule(approximately 0.6 cm in diameter)in the extramural basal segment of the left lower lobe,which suggested multiple lung metastases from rectal cancer.Subsequent treatment and follow-up led to a diagnosis of rectal cancer with left lung metastasis and peripheral adenocarcinoma of the lower lobe of the right lung.CONCLUSION This case report describes the therapeutic journey of a patient with lung metastasis from rectal cancer in addition to primary peripheral adenocarcinoma,thus underscoring the critical roles of multidisciplinary collaboration,personalized treatment strategies,and comprehensive patient rehabilitation guidance.
文摘Lung cancer is among the most prevalent cancers and has the highest mortality rate globally.The diagnosis,pathohistological classification,and molecular testing of lung cancer primarily rely on tissue biopsy or surgical resection.These methods are invasive and associated with limitations,including sample quantity and quality,as well as patient tolerance.Radiomics,an emerging technology,enables the extraction of high-throughput quantitative information from medical images,providing radiomic features applicable to clinical diagnosis and treatment.Significant advancements have been made in the application of radiomics to the diagnosis,molecular detection,efficacy prediction,and prognosis of lung cancer.This review examines the progress in radiomics for individualized and precise diagnosis and treatment of lung cancer in recent years.

文摘BACKGROUND Tuberculosis is among the most devastating infectious diseases worldwide.Spinal tuberculosis is not easy to detect at an early stage,which without effective treatment often leads to spinal deformity and spinal cord damage which in turn cause complications such as paraplegia and quadriplegia.In this study,we established a model using three concentrations of bacteria and carried out a comprehensive evaluation of the model by imaging,general observations,and histopathological and bacteriological studies.AIM To establish a rabbit model of spinal tuberculosis and examine the effect on the model’s efficacy using different concentrations of Mycobacterium tuberculosis(M.tuberculosis)inoculum.METHODS New Zealand rabbits were randomly divided into experimental,control and blank groups.The experimental and control animals were sensitized with complete Freund′s adjuvant,a hole was drilled beneath the upper endplate of the L6 vertebral body and filled with gelfoam sponge.The experimental group was divided into three subgroups(experimental 1,experimental 2,experimental 3)and infused with M.tuberculosis suspension at various concentrations.The control group was inoculated with saline and the blank group received no treatment.The 12-week post-operative survival rates were 100%,80%and 30%in the experimental groups inoculated with concentrations of 106,107 and 108 CFU/mL bacteria,respectively.RESULTS The survival rate of the control and blank groups was 100%.Vertebral body destruction at 8 weeks in the three experimental groups as determined by X-ray analysis was 33.3%,62.5%and 66.7%,and by computed tomography(CT)and 3-dimensional CT 44.4%,75%and 100%,respectively.At 12 weeks,the figures were 44.4%,75%and 100%by X-ray analysis and 44.4%,100%and 100%by CT and 3-dimensional CT,respectively.All surviving rabbits of the experimental groups had vertebral destruction.The positive bacterial culture rates were 22.2%,75%and 66.7%,respectively,in the experimental groups.After being sensitized with complete Freund's adjuvant,large differences were observed in the extent of spinal tuberculosis after inoculation of the rabbits with different concentrations of H37RV standard M.tuberculosis.CONCLUSION The experimental 1 had a low success rate at establishing an infection.The experimental 3 resulted in high mortality and complication rates.The experimental 2 was optimum for establishing a spinal tuberculosis model based on the high level of symptoms observed and the low rabbit mortality.
文摘Among critically ill patients,severe pulmonary and extrapulmonary tuberculosis has high morbidity and mortality.Yet,it is a diagnostic challenge given its nonspecific clinical symptoms and signs in early stages of the disease.In addition,management of severe pulmonary and extrapulmonary tuberculosis is complicated given the high risk of drug-drug interactions,drug-disease interactions,and adverse drug reactions.To help clinicians acquire an up-to-date approach to severe tuberculosis,this paper will provide a narrative review of contemporary diagnosis and management of severe pulmonary and extrapulmonary tuberculosis in critically ill patients.

文摘Background:Long noncoding RNA,LINC01106 exhibits high expression in lung adenocarcinoma(LUAD)tumor tissues,but its functional role and regulatory mechanism in LUAD cells remain unclear.Methods:LINC01106 expression was analyzed in LUAD tissues and its functional impact on LUAD cells was assessed.LUAD cells were silenced with sh-LINC01106 and injected into nude mice to investigate tumor growth.The downstream transcription factors and molecular mechanism were determined using the Human transcription factor database(TFDB)database and Gene Expression Profiling Interactive Analysis(GEPIA)database.Additionally,the impact of linc01106 on autophagy was analyzed by determining the expression of autophagy-related genes(ATGs)in LUAD cells.Results:Our results showed that LINC01106 exhibited upregulation in both LUAD tissues and cell lines.The silencing of LINC01106 demonstrated a suppressive effect on tumorigenesis in a xenograft mouse model of LUAD.Additionally,LINC01106 was found to recruit TATA-binding protein-associated factor 15(TAF15),an RNA-binding protein,thereby enhancing the mRNA stability of TEA domain transcription factor 4(TEAD4).In turn,TEAD4 served as a transcription factor that bound to the LINC01106 promoter and regulated its expression.Further assays indicated that LINC01106 promoted autophagy in LUAD cells by upregulating the expression of autophagy-related genes(ATGs).The silencing of LINC01106 in LUAD cells inhibited autophagy,and cell proliferation,and promoted apoptosis,which all were effectively reversed by ATG5 overexpression.Conclusions:Overall,LINC01106,transcriptionally activated by TEAD4,interacts with TAF15 to promote the stability of TEAD4 and upregulates the expression of ATGs,promoting malignancy of LUAD cells.

文摘BACKGROUND Small cell lung cancer(SCLC)is the most malignant type of lung cancer.Even in the latent period and early stage of the tumor,SCLC is prone to produce distant metastases with complex and diverse clinical manifestations.SCLC is most closely related to paraneoplastic syndrome,and some cases present as paraneoplastic peripheral neuropathy(PPN).PPN in SCLC appears early,lacks specificity,and often occurs before diagnosis of the primary tumor.It is easy to be misdiagnosed as a primary disease of the nervous system,leading to missed diagnosis and delayed diagnosis and treatment.CASE SUMMARY This paper reports two cases of SCLC with limb weakness as the first symptom.The first symptoms of one patient were rash,limb weakness,and abnormal electromyography.The patient was repeatedly referred to the hospital for limb weakness and rash for>1 year,during which time,treatment with hormones and immunosuppressants did not lead to significant improvement,and the condition gradually aggravated.The patient was later diagnosed with SCLC,and the dyskinesia did not worsen as the dermatomyositis improved after antineoplastic and hormone therapy.The second case presented with limb numbness and weakness as the first symptom,but the patient did not pay attention to it.Later,the patient was diagnosed with SCLC after facial edema caused by tumor thrombus invading the vein.However,he was diagnosed with extensive SCLC and died 1 year after diagnosis.CONCLUSION The two cases had PPN and abnormal electromyography,highlighting its correlation with early clinical indicators of SCLC.
