ABSTRACT

Objective: To investigate the applicability of the 2021 WHO classification of thoracic tumors' new grading system for invasive pulmonary adenocarcinoma (IPA) with different clinical stages and its correlation with the characteristics of targeted genes' variation. Methods: A total of 2 467 patients with surgically resected primary IPA in Shanghai Pulmonary Hospital, Shanghai, China from September to December 2020 were retrospectively analyzed. Eligible cases were graded using the new grading system of IPA of the 2021 WHO classification of thoracic tumors. The clinicopathological data and targeted-gene abnormality were collected. The utility of new grading system of IPA in different clinical stages was investigated. The correlation of clinicopathological features and targeted-gene abnormality in different grades of IPA were compared. Results: All 2 311 cases of IPA were included. There were 2 046 cases of stage Ⅰ IPA (88.5%), 169 cases of stage Ⅱ (7.3%), and 96 cases of stage Ⅲ (4.2%). According to the new classification system of IPA, 186 cases (9.1%), 1 413 cases (69.1%) and 447 cases (21.8%) of stage-Ⅰ adenocarcinoma were classified as Grade 1, Grade 2 and Grade 3, respectively. However, there were no Grade 1 adenocarcinomas in stages Ⅱ and Ⅲ cases. Among stage-Ⅱ and Ⅲ IPA cases, there were 38 Grade 2 cases (22.5%) and 131 Grade 3 cases (77.5%), and 3 Grade 2 cases (3.1%) and 93 Grade 3 cases (96.9%), respectively. In stage-Ⅰ cases, no tumor cells spreading through airspace (STAS), vascular invasion or pleural invasion was found in Grade 1 of IPA, while the positive rates of STAS in Grade 2 and 3 IPA cases were 11.3% (159/1 413) and 73.2% (327/447), respectively. There was a significant difference among the three grades (P<0.01). Similarly, the rates of vascular and pleural invasion in Grade 3 IPA cases were 21.3% (95/447) and 75.8% (339/447), respectively, which were significantly higher than those of 1.3% (19/1 413) and 3.0% (42/1 413) in Grade 2 (P<0.01). EGFR mutational rates in Grades 1, 2 and 3 IPA were 65.7% (94/143), 76.4% (984/1 288) and 51.3% (216/421), respectively. The differences among the three grades were statistically significant (P<0.01). No fusion genes were detected in Grade 1 IPA, while the positive rates of ROS1 and ALK fusion genes in Grade 3 were 2.4% (10/421) and 8.3% (35/421), respectively, which were significantly higher than that of 0.5% (7/1 288) and 1.6% (20/1 288) in Grade 2 (P<0.01). In stage-Ⅱ cases, only EGFR mutation rate in Grade 2 adenocarcinoma (31/37, 83.8%) was higher than that in Grade 3 adenocarcinoma (71/123, 57.7%; P<0.01). However, the correlation between the new grade system of IPA and the distribution characteristics of targeted-gene variation cannot be evaluated in stage Ⅲ cases. Conclusions: The new grading system for IPA is mainly applicable to clinical stage-Ⅰ patients. Tumor grades of IPA are strongly correlated with the high-risk factors of prognosis and the distribution features of therapeutic targets. It is of great significance and clinical value to manage postoperative patients with early-stage IPA.

ABSTRACT

Objective: To investigate the clinicopathological features of pulmonary granular cell tumors (pGCTs) and to improve the diagnostic accuracy of the tumor. Methods: A total of 5 pGCTs were diagnosed from February 2016 to January 2022 at Shanghai Pulmonary Hospital, Tongji University School of Medicine and Fudan University Shanghai Cancer Center, China. Immunohistochemical staining, and analysis of the clinicopathological characteristics were performed. Results: The average age of the pGCTs patients was 46 years (ranging from 24 to 54 years), with 3 females and 2 males. One case occurred in the bronchus with multiple nodules in the lung, 2 cases occurred in the bronchial opening, and 2 cases were solitary nodules in the lung. The maximum diameter of the tumors ranged from 12 to 15 mm (mean size 14 mm). Microscopically, the tumor showed infiltrative growth and consisted of round, oval or polygonal cells. Abundant eosinophilic cytoplasm was noted, and the nucleoli were prominent. None of the 5 cases showed any mitosis or necrosis. Immunohistochemical and histochemical study showed positive staining for S-100 (5/5), SOX10 (5/5), Vimentin (5/5), TFE3 (4/5), PAS (3/5), and amylase-digested-PAS (3/5), while 4 cases were negative for CD68. TFE3 FISH analyses on 2 cases showed that no signal abnormality was detected in these 2 cases. The average proliferation index of Ki-67 was 2.2% (range 0-5%). There was no recurrence in 4 cases of pGCTs with a follow-up time ranging from 2 months to 60 months. Conclusions: pGCTs are very rare tumors, most likely originating from Schwann cells. Immunohistochemical staining is the conventional diagnostic tool for pGCTs diagnosis. Recognition of this entity is essential for pathologists to avoid misdiagnosis and unnecessary treatments.

ABSTRACT

Objective: To investigate and elucidate the clinicopathological and prognostic characteristics of SMARCA4-deficient non-small cell lung cancer. Methods: The clinicopathological and prognostic data were collected in 127 patients with SMARCA4-deficient non-small cell lung cancer diagnosed in Shanghai Pulmonary Hospital, Shanghai, China from January 2020 to March 2022. The variation and expression of biomarkers related to treatment were retrospectively reviewed. Results: One hundred and twenty-seven patients were eligible for enrollment. Among them 120 patients (94.5%) were male and 7 cases (5.5%) were female, while the average age was 63 years (range 42-80 years). There were 41 cases (32.3%) of stage Ⅰ cancer, 23 cases (18.1%) of stage Ⅱ, 31 cases (24.4%) of stage Ⅲ and 32 cases (25.2%) of stage Ⅳ. SMARCA4 expression detected by immunohistochemistry was completely absent in 117 cases (92.1%) and partially absent in 10 cases (7.9%). PD-L1 immunohistochemical analyses were performed on 107 cases. PD-L1 was negative, weakly positive and strongly positive in 49.5% (53/107), 26.2% (28/107) and 24.3% (26/107) of the cases, respectively. Twenty-one cases showed gene alterations (21/104, 20.2%). The KRAS gene alternation (n=10) was most common. Mutant-type SMARCA4-deficient non-small cell lung cancer was more commonly detected in females, and was associated with positive lymph nodes and advanced clinical stage (P<0.01). Univariate survival analysis showed that advanced clinical stage was a poor prognosis factor, and vascular invasion was a poor predictor of progression-free survival in patients with surgical resection. Conclusions: SMARCA4-deficient non-small cell lung cancer is a rare tumor with poor prognosis, and often occurs in elderly male patients. However, SMARCA4-deficient non-small cell lung cancers with gene mutations are often seen in female patients. Vascular invasion is a prognostic factor for disease progression or recurrence in patients with resectable tumor. Early detection and access to treatment are important for improving patient survivals.

ABSTRACT

Objective: To investigate the clinicopathological, immunophenotypic, and molecular genetic features of bronchial sialadenoma papilliferum (BSP). Methods: Four cases of BSP collected at the Shanghai Pulmonary Hospital from May 2018 to June 2021 were retrieved and analyzed. These cases were evaluated for their clinical, histological, immunohistochemical (IHC) and genomic features. The patients were followed up and relevant literature was reviewed. Results: All four patients were male, aged from 55 to 75 years (mean 62 years), with tumor diameter of 6 to 21 mm (mean 13.5 mm), and lesions were located in the left lower lobe (n=2), right lower lobe (n=1), and trachea (n=1). They were characterized by a combination of surface exophytic endobronchial papillary proliferation and an endophytic two-cell layered ductal structure. IHC staining showed that CK7 and EMA were strongly positive in ductal epithelium; p63, p40, CK5/6 were positive in ductal and papillary basal cells; SOX10 was positive in ductal epithelium and basal cells; S-100 was positive in basal cells and ductal epithelium in two cases. Next generation sequencing showed that two cases harbored BRAF V600E mutation. Conclusions: BSP is an extremely rare primary lung tumor arising from the salivary gland under bronchial mucosa. The primary treatment choice of this tumor is complete surgical resection. The diagnosis and differential diagnosis of this tumor depend on classic histomorphologic and IHC features, and BRAF V600E gene mutation can be detected.

ABSTRACT

Objective: To investigate the clinicopathological features, diagnostic criteria and differential diagnosis of primary salivary gland-type duct carcinoma of lung(LSDC). Methods: Two patients with LSDC after surgical resection in Shanghai Pulmonary Hospital from 2020 to 2021 were included; their clinical parameters as well as pathological, immunohistochemical and molecular characteristics of the tumors were analyzed. The relevant literature was also reviewed. Results: Both patients were male, aged 49(case 1) and 64(case 2) years, respectively, and with a history of smoking. The chest computed tomography scan showed both lesions to be centrally located. Gross examination showed the maximum diameters were 16 mm and 35 mm, respectively. The histomorphology of LSDC resembled ductal carcinoma of breast, with intraductal islands of neoplastic cells, which also formed solid nests, papillary, micropapillary and cribriform structures. There was frequent accompanying comedo-like necrosis. The neoplasm cells were markedly heteromorphic, possessing large irregular nuclei with prominent nucleoli, abundant eosinophilic or clear cytoplasm, and mitotic figures were common. Both cases of LSDC were immunoreactive for CKpan, CK7, AR, HER2 staining was (2+) and were negative for TTF1, Napsin A, p40, GATA3, mammaglobin, GCDFP15, SOX10, PSA, P504S, ER, PR, vimentin, S-100, SMA, CK5/6 and p63. The tumor showed double-layer cell structure of the duct, and some basal cells/myoepithelial cells expressed p40 and CK5/6. Case 1 had no gene mutation while case 2 harbored TP53 and KMT2A gene mutation detected by next generation sequencing. Conclusions: LSDC is a very rare and highly aggressive salivary-type malignant tumor. The postoperative diagnosis mainly depends on histopathology and immunohistochemistry, attention should be paid to differential diagnosis to prevent missed diagnosis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the protective effect of exendin-4 against diabetic cardiomyopathy in mice and explore the underlying mechanism.</p><p><b>METHODS</b>C57BL/6J mice were randomly divided into normal control group with normal diet and diabetic group with high-fat diet for 4 weeks before streptozotocin injection. The successfully established diabetic mouse models were divided into diabetic group with exendin-4 treatment and diabetic control group for daily treatment with intraperitoneal injection of 1 nmol/kg exendin-4 and saline of equivalent volume for 8 weeks, respectively. The physiological parameters such as blood glucose and body weight were recorded. RT-PCR was used to examine the transcription levels of genes related with myocardial hypertrophy and fibrosis and the genes related with mitochondrial functions including PGC1α, NRF and CytoC. The expressions of oxidative stress markers and Sirt1/PGC1 proteins were measured using Western blotting. and HE staining was used to observe the myocardial structural changes in the mice.</p><p><b>RESULTS</b>Compared with the normal control mice, the mice in diabetic control group showed significantly increased blood glucose and blood lipid levels (P<0.001), which were obviously improved by Exendin-4 treatment. The expressions of ANP, BNP, TGFβ1, CytoC1 and NOX1 were significantly increased (P<0.05) while Sirt1, PGC1α, NRF and SOD1 expression were markedly decreased in the myocardial tissue of the diabetic mice (P<0.05). Exendin-4 treatment resulted in obviously reduced expressions of ANP, BNP, TGFβ1, CytoC1 and NOX1 (P<0.05) and increased expressions of Sirt1, PGC1α, NRF and SOD1 (P<0.05) in the diabetic mice.</p><p><b>CONCLUSIONS</b>Exendin-4 protects against myocardial injury in diabetic mice by improving mitochondrial function and inhibiting oxidative stress through the Sirt1/PGC1α signaling pathway.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the prevalence, etiology and clinical characteristics of adrenal lesions detected by abdominal computed tomography (CT).</p><p><b>METHODS</b>This retrospective study was conducted in patients with adrenal lesions detected by abdominal CT examinations in Nanfang Hospital between July, 2014 and June, 2015. The clinical data of the patients were collected for analysis of the demographics, comorbidities, imaging characteristics, biochemical profiles, clinical diagnosis and intervention.</p><p><b>RESULTS</b>A total of 939 patients with adrenal lesions were identified from 19 004 patients undergoing abdominal CT scan over the defined period. The mean age of the patients was 53.2 years and 560 of the patients were male. Among the total cases with adrenal lesions, the percentages of cases with adrenal masses tended to increase progressively with age. Endocrine studies were done in 270 of the total patients, which identified non-functioning masses in 38.9%, primary aldosteronism in 16.3%, Cushing's syndrome in 4.1%, subclinical Cushing's syndrome in 7.0%, and pheochromocytomas in 7.0% of the cases. Adrenal incidentalomas was detected in 191 patients, with a detection rate of 1.0% among the overall patients undergoing abdominal CT scans. Imaging study detected adenomas (70.3%), cortical carcinomas (2.4%), and metastases (0.5%). Of 191 patients with adrenal incidentalomas, only 76 (39.8%) underwent endocrine evaluation, including 34 with nonfunctioning adrenal masses, 17 with pheochromocytoma, 7 with primary aldosteronism, and 5 with subclinical Cushing's syndrome.</p><p><b>CONCLUSION</b>s The overall detection rates of adrenal lesions and adrenal incidentalomas by abdominal CT were 4.9% and 1.0%, respectively, in our cohort of patients undergoing the examination over the defined period. Although most of the lesions were benign and nonfunctioning, malignant and functional lesions were also detected. As many as 60% of the patients with adrenal incidentalomas did not have hormonal testing. Clinicians need to have greater awareness of adrenal incidentalomas and standard protocol for its management should be established.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expressions of inflammation- and fibrosis-related genes in perinephric and subcutaneous adipose tissues in patients with adrenocorticotropic hormone (ACTH)-independent Cushing's syndrome.</p><p><b>METHODS</b>The perinephric and subcutaneous adipose tissues adipose tissues were obtained from 8 patients with ACTH-independent Cushing's syndrome undergoing laparoscopic retroperitoneal adrenalectomy. Real-time PCR was used to detect the mRNA expression levels of interleukin 6 (IL-6), tumor necrosis factor-α (TNF-α), matrix metallopeptidase 2 (MMP-2), TIMP metallopeptidase inhibitor 1 (TIMP-1), early growth response 1 (EGR1), CCAAT/enhancer binding protein β(CEBPβ), uncoupling protein 1(UCP-1), PPARγ coactivator 1 alpha (PGC1α) and cell death-inducing DFFA-like effector a (CIDEA).</p><p><b>RESULTS</b>The mRNA level of CIDEA was significantly higher in the perinephric adipose tissue (peri-N) than in the subcutaneous adipose tissue (subQ) (P<0.05). The expressions of CEBPβ, UCP-1, and PGC1α mRNA in the peri-N were similar with those in the subQ. The expressions of IL-6, TIMP1 and EGR1 mRNA in the subQ were significantly higher than those in the peri-N (P<0.05). No significant difference in TNF-α and MMP-2 mRNA levels was found between peri-N and subQ.</p><p><b>CONCLUSION</b>The expression levels of the inflammation- and fibrosis-related genes are higher in the subQ than in the peri-N of patients with ACTH-independent Cushing's syndrome, suggesting that chronic exposure to endogenous hypercortisolism may cause adipose tissue dysfunction.</p>

ABSTRACT

The paper is aimed at studying the diversity of endophytic fungi community from Paris polyphylla var. yunnanensis, and to provide a scientific basis for the utilization value of the endophytic fungi as bioactive material resources. In the present study, endophytic fungi were isolated from roots, rhizomes and leaves of wild P. polyphylla var. yunnanensis collected from Baoshan, Heqing county and Songming city of Yunnan province, and identified and classified by morphological methods together with its ITS sequence analysis. Seven and forty-nine strains of endophytic fungi were isolated from P. polyphylla var. yunnanensis. They were identified belonging to 41 genus. In these 41 genus, 3 genus exist in root only, 12 genus only exist in rhizome and 8 genus only exist in leaf. There was difference in endophytic fungi isolated from different sample sites. Endophytic fungi diversity from rhizomes of Heqing site was the highest. Endophytic fungi similarity coefficient was low among different sites and tissues. Based on these results, it is reasonable to propose that endophytic fungi of P. polyphylla var. yannanensis from different tissue and different sample sites has a certain difference which is possibly relate to their different habitats, different structure and composition of each tissue.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinical manifestations and radiological characteristics, diagnostic methods and outcomes of pulmonary mucosa-associated lymphoid tissue-derived(MALT) lymphoma.</p><p><b>METHODS</b>A retrospective review of clinical, radiological and follow-up data of 29 pulmonary MALT lymphoma cases at Shanghai Pulmonary Hospital affiliated to Tong Ji University from January 2002 to June 2010 was performed.</p><p><b>RESULTS</b>Among these patients, there were 19(65.5%) males and 10 (34.5%) females aged from 27 to 73 (median 53) years old. Common clinical manifestations were cough (51.7%), fever (20.7%), apnea (17.2%), chest pain (17.2%), fatigue (13.8%) and weight loss (13.8%), while 9(31.0%) cases had no symptoms at diagnosis. The characteristics of the chest CT showed that 22 (75.9%) of the cases had patch infiltration or consolidation of the lung, 7(24.1%) of the cases had mass, and 15 (51.7%) unilateral and 14(48.3%) bilateral lesions. Their diagnosis duration varied between 0.5 and 96 months. 18(62.1%) cases were confirmed by surgery (15 open lung and 7 video-assisted thoracic surgery, VAST), 4 (13.8%) by percutaneous lung biopsy, 5 (17.2%) by bronchoscopic biopsy, and 2 (6.9%) by peripheral lymph node biopsy. The treatment methods included surgery, combined chemotherapy, radiotherapy and Chinese herbal medicine. The 1- and 3-year-survival rates were 92.3% and 87.4%, respectively.</p><p><b>CONCLUSIONS</b>Pulmonary MALT lymphoma is atypical in clinical manifestations and radiological characteristics, and easy to be misdiagnosed. Local diseases are mainly treated by operation while extensive diseases receive combined chemotherapy. A proper diagnosis is mainly based on pathological biopsy. Patients with MALT lymphoma have a favorable outcome. Poor prognosis may be connected with poor performance status and long diagnosis duration.</p>
