ABSTRACT

A 50-year-old woman was diagnosed with iron deficiency anemia on general medical examination. Further, contrast-enhanced abdominal CT and magnetic resonance imaging revealed a large hypervascular mass with internal degeneration and necrosis in the retroperitoneal space. She was referred to our hospital for further evaluation and treatment. Because the paraganglioma was most likely as the imaging diagnosis, 123I-MIBG scintigraphy was performed. It revealed the marked abnormal accumulation in the retroperitoneal lesion indicating the paraganglioma and no other abnormal accumulation was noted. Several plasma catecholamines and their urinary metabolites were normal. On the subsequent 18F-FDG PET/CT, high FDG uptake was found in the retroperitoneal lesion (SUVmax=38). FDG uptake was also found in a small nodule at the base of the lower lobe of the right lung (SUVmax= 9.8). Contrast-enhanced imaging revealed a hypervascular nodule at the base of the right lung, suggesting pulmonary metastasis of a paraganglioma. The abdominal lesion and right lung nodule were excised, and retroperitoneal paraganglioma and pulmonary metastasis were diagnosed based on the pathology findings. In this case, 18F-FDG PET/CT was useful in the search for paraganglioma metastasis. We report a relationship between 123I-MIBG accumulation and 18F-FDG uptake in paraganglioma and review the relevant literature.

ABSTRACT

BACKGROUND: Preoperative computed tomography-guided marking can help identify small non-palpable pulmonary nodules during surgery. However, this technique is associated with the risk of air embolism. We retrospectively evaluated whether small pulmonary nodules could be intraoperatively localized using cone-beam computed tomography (CBCT). METHODS: A hybrid operating room permitting stable lateral positioning and scanning from the pulmonary apex to the base was used in all patients. CBCT images were obtained using a 10-s protocol with 180º rotation of the C-arm flat panel detector around the patient. Clips were placed on the visceral pleura to help guide pulmonary nodule localization. Partial pulmonary resection was performed using video-assisted thoracoscopic surgery at the predicted nodule site. RESULTS: Between July 2013 and June 2019, 132 patients with 145 lesions underwent this procedure at our center. The detection rate of lesions on CBCT was 100%. The pathological diagnoses were primary lung cancer, metastatic pulmonary tumors, and benign lesions. The average consolidation-to-tumor ratio was 0.65 for all nodules, with ratios of 0.33, 0.96, and 0.70 for primary lung cancer, metastatic pulmonary tumors, and benign lesions, respectively. No complications related to this localization method were observed. CONCLUSIONS: CBCT-guided intraoperative localization is safe and feasible for non-palpable small pulmonary nodules. This technique may eliminate the risk of serious complications such as air embolism.

ABSTRACT

INTRODUCTION: When the management of an anterior mediastinal tumor requires general anesthesia, airway narrowing and obstruction may occur secondary to muscle relaxation. PRESENTATION OF CASES: Two men (ages, 15 and 36 years) presented with a giant anterior mediastinal tumor and central airway obstruction. We used Dumon stents to effectively secure the airway in both patients. After chemotherapy, stent removal was safely performed in each case because the tumor was substantially smaller. DISCUSSION: Dumon stents effectively secured the airway. These stents were easily removed after chemotherapy without severe complications. CONCLUSION: Temporary stenting is useful in patients with a giant anterior mediastinal tumor who require general anesthesia.

ABSTRACT

BACKGROUND: Pulmonary interstitial emphysema is a rare, abnormal condition in which air pressure from the alveolar airspace tears the adjacent interstitial tissues of the lung and causes the formation of cystic spaces. Pulmonary interstitial emphysema is a known indication for mechanical ventilation in premature infants with neonatal respiratory distress syndrome, and it can be observed in various types of interstitial lung disease. Nevertheless, its pathogenesis and clinical impact remain unknown. METHODS: We reviewed data from 433 cases of interstitial lung disease from an external consultation archive. Multidisciplinary diagnosis along with clinical and follow-up data, including events of air leaks such as pneumothorax and mediastinal emphysema, were obtained and compared to those of 150 control cases of interstitial lung disease without pulmonary interstitial emphysema. RESULTS: We found 22 (5.1%) cases of interstitial lung disease with pulmonary interstitial emphysema. The diagnoses included idiopathic pulmonary fibrosis (5/22 [22.7%]), pleuroparenchymal fibroelastosis (4/22 [18.2%]), chronic hypersensitivity pneumonia (4/22 [18.2%]), and others (9/22 [40.9%]). Cases involving pulmonary interstitial emphysema demonstrated a significantly higher frequency of air leaks than did those without pulmonary interstitial emphysema (12/22 [54.5%] versus 23/150 [15.3%]; P < 0.001; odds ratio, 6.63) and were associated with worse prognosis (P = 0.009 [log-rank]) and a lower median percent forced vital capacity (73.2% versus 84.0%; P < 0.001). CONCLUSIONS: We found that pulmonary interstitial emphysema is an independent factor for poor prognosis, which also shows a trend to cause air leaks, including pneumothorax and mediastinal emphysema.

ABSTRACT

BACKGROUND: Lung function in the late postoperative phase after pulmonary lobectomy is insufficiently characterized. This study aimed to appraise lung function in the late postoperative phase according to vital capacity (VC) and forced expiratory volume in 1 second (FEV1) in patients who underwent pulmonary lobectomy. METHODS: Pre- and postoperative VC and FEV1 were reviewed in 112 patients who underwent pulmonary lobectomy. Postoperative lung volume was assessed >1 year after surgery. Postoperative decreases in VC and FEV1 were compared with preoperative predicted values among patients who underwent resection of specific lobe. Determinants effecting a decrease in lung function were also investigated. RESULTS: A mean postoperative decreased VC of 10.5%±1.8% was recorded in patients who underwent right upper lobectomy (RU), 7.2%±1.5% for right middle lobectomy (RM), 14.3%±2.3% for right lower lobectomy (RL), 16.6%±3.0% for left upper lobectomy (LU), and 14.7%±2.5% for left lower lobectomy (LL). Corresponding FEV1 values were 14.8%±1.8% for RU, 11.9%±4.0% for RM, 14.9%±2.3% for RL, 17.9%±2.9% for LU, and 15.1%±2.4% for LL. The actual decreasing rate of VC was overestimated in patients who underwent RU, RL, LU, and LL. In contrast, FEV1 was overestimated only in patients who underwent RL and LL. Patients with chronic obstructive pulmonary disease (COPD) exhibited significantly better preservation of FEV1. CONCLUSIONS: Patients scheduled for RL and LL, or those with COPD, appeared to exhibit preserved lung function in the late postoperative phase after pulmonary lobectomy.

ABSTRACT

Transforming acidic coiled-coil-containing protein 3 (TACC3), a microtubule regulator, is associated with various cancers. However, the relationship between TACC3 and soft tissue sarcomas (STS) remains unclear. We investigated the expression of TACC3 in 136 STS patient samples using immunohistochemical (IHC) staining, and the statistical associations between TACC3 expression and clinicopathological characteristics were evaluated. Additionally, the expression levels of the tumor suppressor p53 and of the cell proliferation marker Ki-67 were also assessed by IHC. High TACC3 expression was detected in 94/136 of STS cases (69.1%), and significantly correlated with higher grade according to the French Fédération Nationale des Centres de Lutte Contre le Cancer system (P<0.0001), poorer tumor differentiation (P<0.0001), increased mitotic counts (P<0.0001), advanced stage per American Joint Committee on Cancer guidelines (P<0.0001), higher p53 expression (P = 0.0487), higher Ki-67 expression (P<0.0001), and undergoing postoperative therapy (P = 0.0001). Disease-free survival (DFS) and overall survival (OS) of patients with high TACC3 expression were significantly shorter (P<0.0001 and P<0.0001, respectively). On multivariate analyses, high TACC3 expression was an independent negative prognostic factor for both DFS and OS (hazard ratio [HR]: 3.074; P = 0.0235 and HR: 8.521; P = 0.0415, respectively). Our results suggest that TACC3 is an independent prognostic factor and may be a novel therapeutic target for the treatment of STS.

ABSTRACT

BACKGROUND: A clear survival benefit has been reported for lung metastasectomy for colorectal cancer, and several clinicopathological prognostic factors have been proposed in the past. However, clinical advances, such as chemotherapy and radiographic imaging, should have improved patient outcome and may have altered prognosticators. This study aimed to assess patient survival and determine prognostic factors for survival and recurrence in patients who underwent initial lung metastasectomy for colorectal cancer in the modern clinical era. METHODS: Clinicopathological data and outcomes of 59 patients who underwent curative initial lung metastasectomy for colorectal cancer from 2004 to 2012 at a single institution in Japan were retrospectively investigated. Survival was estimated using the Kaplan - Meier method, and Cox proportional hazards regression models were used to estimate the prognostic impacts of each variable in univariate and multivariate analysis. RESULTS: The 5-years overall and disease-free survival rates were 54.3 and 40.6%, respectively. A disease-free interval < 24 months after colorectal cancer resection (P = 0.004) and a serum carcinoembryonic antigen ≥ 5.0 ng/mL before initial lung metastasectomy (P = 0.015) were independent predictors for poor overall survival. Moreover, the disease-free interval after colorectal cancer resection < 24 months (P = 0.010) and a colorectal cancer with N2 stage disease (P = 0.018) were independently associated with poor disease-free survival. On the other hand, the number of lung metastasis was not identified as a poor prognostic factor for both overall and disease-free survival. CONCLUSIONS: Our findings demonstrated similar or slightly better overall survival, and substantially favorable disease-free survival as compared with past reports. Poor prognostic factors for overall survival appeared not to differ from those of past studies, although this modern series did not determine the number of lung metastasis as a poor prognostic factor, which should be investigated in future studies. Moreover, initial lung metastasectomy is not expected to be a curable treatment for patients with both a short disease-free survival after colorectal cancer resection and colorectal cancers with N2 stage disease.

ABSTRACT

GATA binding protein-3 (GATA3) is a transcription factor that regulates cell differentiation and maintenance in some types of normal cells. This study aimed to investigate the association between GATA3 expression and primary lung adenocarcinoma and to clarify the clinical significance of GATA3 expression in lung adenocarcinoma. Immunohistochemical GATA3 expression was evaluated using completely resected lung adenocarcinoma samples from 95 cases. GATA3 immunohistochemical staining was performed and scored. Associations between clinicopathological factors and GATA3 expression were analyzed by using the χ2 test and Fisher exact test. The Kaplan-Meier method was used to analyze overall survival (OS) and disease-free survival (DFS). Forty-nine cases expressed high levels of GATA3, which were associated with lymphatic invasion (P=.003). In univariate and multivariate analyses, vascular invasion (P<.001) and high GATA3 expression (P=.023) were identified as independent risk factors for OS. Higher pathological stages (P=.012), vascular invasion (P=.010), and high GATA3 expression (P=.009) were identified as independent risk factors for DFS. The high GATA3 expression group exhibited statistically worse OS (P=.031) and DFS (P=.011) than the low-expression group based on the Kaplan-Meier curves. In resected lung adenocarcinoma, high GATA3 expression is associated with poorer prognosis for both OS and DFS. Therefore, the immunohistochemical evaluation of GATA3 represents a potentially useful prognostic tool for postoperative patients.

ABSTRACT

OBJECTIVE: Recent studies have investigated the significance of GATA3 expression in patients with various malignant tumors. However, no previous studies have evaluated the clinicopathological importance of GATA3 expression in soft tissue sarcomas (STS) patients. METHODS: We evaluated GATA3 expression in 76 STS cases using immunohistochemical analysis, and statistically compared clinicopathological characteristics between GATA3-positive and GATA3-negative cases. RESULT: GATA3-positive expression was significantly associated with a higher mitotic count (P < 0.0001). Disease-free survival (DFS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0104). Overall survival (OS) of GATA3-positive cases was significantly shorter than that of cases without GATA3 expression (P = 0.0006). GATA3-positive expression was significantly associated with shorter DFS in both univariate analysis (hazard ratio [HR], 2.719; P = 0.012) and multivariate analysis (HR, 2.711; P = 0.014). GATA3-positive expression was also significantly associated with worse OS in both univariate analysis (HR, 5.730; P = 0.0007) and multivariate analysis (HR, 5.789; P = 0.0008). CONCLUSION: These results indicate that GATA3 is an independent prognostic factor and suggest that evaluation of GATA3 expression might enable more effective clinical follow-up using prognostic stratification of STS patients.

ABSTRACT

PURPOSE: The immune checkpoint of the programmed death 1/programmed death ligand 1 (PD-1/PD-L1) pathway is believed to play an important role in evasion of host antitumor immune surveillance in various malignancies; however, little is known about its role in thymic carcinoma. This study investigated PD-1/PD-L1 expression and its association with clinicopathologic features, the expression of immune-related proteins in tumor-infiltrating lymphocytes (TIL), and patient prognosis. EXPERIMENTAL DESIGN: PD-L1 and PD-1 expression was evaluated by IHC in 25 thymic carcinoma tissue specimens. Copy number alterations of the PD-L1 gene in 11 cases were assessed in formalin-fixed, paraffin-embedded material using qRT-PCR. RESULTS: Compared with normal subjects, 3 thymic carcinoma patients showed an increase in PD-L1 copy number, whereas 8 did not. PD-L1 was significantly overexpressed in cases with copy number gain as compared with normal cases. High PD-L1 expression was associated with higher disease-free and overall survival rates as compared to cases with low expression. Prognostic analysis revealed low PD-L1 expression and high number of PD-1(+) TILs as significant predictors of poor survival, together with Masaoka-Koga stage IVa/IVb disease and incomplete resection. In the quantitative analysis of TILs, PD-L1 expression correlated proportionally with the number of infiltrating CTLs. CONCLUSIONS: Here, for the first time, we report that PD-L1 and PD-1 expression might be useful prognostic predictors in thymic carcinoma. Further studies are expected to substantiate the prognostic value of PD-L1 and PD-1 expression, and the potential efficacy of targeting the PD-1/PD-L1 pathway in thymic carcinoma via immunotherapy.

ABSTRACT

BACKGROUND: Programmed death ligand 1 (PD-L1) has been reported to be expressed in various malignancies and is considered to be a prognostic factor and an immunotherapeutic target. The aim of this study was to characterize PD-L1 expression in thymoma and determine statistical associations between this expression and clinical features. METHODS: We reviewed formalin-fixed, paraffin-embedded tissue specimens from 82 thymoma cases accumulated at Kurume University, the majority of which achieved surgical complete resection. Expression of PD-L1 was evaluated by immunohistochemistry. Statistical associations between PD-L1 expression and clinicopathologic features were evaluated by using χ(2) test and Fisher's exact test. Disease-free survival and overall survival curves were established by the Kaplan-Meier method and compared using a log-rank test. Predictive factors for disease-free survival after complete resection were analyzed by using a Cox proportional hazards model in univariate and multivariate analysis. RESULTS: Overall, 44 thymoma cases (54%) revealed high PD-L1 expression. High PD-L1 expression was statistically associated with Masaoka stage III/IV disease (p = 0.043) and World Health Organization type B2 or B3 thymoma (p = 0.044). Disease-free survival after complete resection in high PD-L1 expression was significantly worse than that in low PD-L1 expression (p = 0.021), although there was no significant difference in overall survival (p = 0.957). Multivariate analysis also revealed high PD-L1 expression as an independent risk factor for recurrence (p = 0.008). CONCLUSIONS: Characterization of PD-L1 expression in thymoma should enable more effective clinical approaches, including prognostic stratification of patients and potential use of anti-PD-L1 antibody immunotherapy.

ABSTRACT

Primary thymic adenocarcinoma is extremely rare. Moreover, thymic pure epithelial benign neoplasms are extremely rare. We encountered a cystic tumor almost purely composed of goblet cell-like mucus-producing cells of the thymus. A mass lesion of the mediastinum was detected in a 54-year-old man. The gross specimen presented a unilocular cystic lesion containing abundant mucin, measuring 8 × 5.5 × 4.5 cm. Microscopic examination revealed a cystic tumor consisting of bland mucus-producing cells resembling goblet cells and forming tiny daughter cysts within the dense fibrous capsule. No destructive growth or infiltration into surrounding thymic tissue was observed. Papillary growth was found in a small focus. Immunohistochemically, tumor cells were positive for cytokeratin 20 and caudal type homobox 2, which are representative markers of enteric differentiation. The patient has been well without any recurrence for approximately ten years after the operation. Thus, the tumor should be regarded as a mucinous cystic tumor in the thymus. Very recently, thymic adenocarcinoma with enteric differentiation was proposed as a novel subtype of thymic carcinoma. This case could be regarded as a benign counterpart of adenocarcinoma of the thymus, enteric type. A further follow-up study is required to confirm the exact biological behavior of this tumor.

ABSTRACT

Gene and protein abnormalities of anaplastic lymphoma kinase (ALK) play an important role in the pathogenesis of various cancers and serve as important therapeutic targets. We investigated ALK protein expression, phosphorylation, and genetic aberrations using fluorescence in situ hybridization (FISH) in 81 soft tissue tumor samples: inflammatory myofibroblastic tumor, n=1; alveolar soft part sarcoma, n=2; leiomyosarcoma, n=10; well-differentiated liposarcoma, n=7; pleomorphic liposarcoma, n=2; extraskeletal osteosarcoma, n=1; epithelioid sarcoma, n=1; synovial sarcoma, n=4; malignant peripheral nerve sheath tumor, n=4; undifferentiated pleomorphic sarcoma, n=19; rhabdomyosarcoma, n=6; myxofibrosarcoma, n=8; myxoid liposarcoma, n=11; fibrosarcoma, n=4; and desmoid-type fibromatosis, n=1. ALK protein expression, gene signal gain (without translocation), and phosphorylation were observed in 33/81 (40.7%), 55/81 (67.9%), and 30/81 (37.0%) tumor samples, respectively. ALK protein expression was statistically associated with phosphorylation, but not with gene signal gain. ALK phosphorylation-positive cases showed a statistically worse metastasis-free survival compared with phosphorylation-negative cases (P=0.0215). Particularly, metastasis of myxoid liposarcoma was associated with ALK phosphorylation (P=0.0019), but not with ALK protein expression or gene signal gain. However, the prognosis had no association with ALK protein expression, gene signal gain, or phosphorylation. ALK protein expression and phosphorylation play an important role in tumor biology and provide potential therapeutic targets for soft tissue tumors. Future research should focus on the oncogenic role and the efficacy of potential inhibitors of ALK.
