RESUMEN

A ganglioneuroma is a rare, benign, neurogenic tumor originating from the sympathetic ganglion. Mediastinal ganglioneuroma are mostly detected in children, typically around 10 years of age, and are rarely identified in adults. Herein, we report two surgically resected cases of mediastinal ganglioneuroma in adults. In Case 1, a 53-year-old man, without any symptom, underwent a computed tomography, revealing a 3.2 cm well-defined paravertebral superior mediastinal tumor with long craniocaudal axis. In case 2, a 29-year-old woman presented with newly-developed ptosis and a history of left-sided facial hypohidrosis since the age of 10. Chest computed tomography (CT) revealed a 7.8 cm well-defined paravertebral superior mediastinal tumor with long craniocaudal axis. Both patients were initially suspected to have neurogenic tumors, particularly schwannomas. They underwent mediastinal tumor resections, requiring sympathetic nerve trunk dissection. Pathological examination confirmed the diagnosis of ganglioneuromas in both cases. Mediastinal ganglioneuroma must be differentiated from schwannoma, the most common neurogenic tumor in adults. Unlike schwannoma, ganglioneuroma cannot be enucleated, therefore attention should be focused on complications associated with sympathetic nerve trunk dissection, such as Horner's syndrome, hyperhidrosis, and arrhythmia. Identifying this rare entity and its characteristic imaging aids in preoperative differentiation, strategizing surgical approaches, and predicting complications.

RESUMEN

We report a case of pulmonary metastasis from hilar cholangiocarcinoma successfully treated by stereotactic body radiotherapy. The patient was a 70-year-old woman who underwent extended left hemi-hepatectomy with bile duct reconstruction for hilar cholangiocarcinoma at the age of 67. Pathological diagnosis indicated a well-differentiated adenocarcinoma. We followed up the patient without adjuvant chemotherapy. Nineteen months after the initial resection, a solitary pulmonary metastasis was detected in the right upper lobe. The patient received gemcitabine plus cisplatin(GC)therapy. After 4 courses of GC therapy, the size of the pulmonary metastasis was unchanged. Therefore, we performed a thoracoscopic wedge resection. Pathological diagnosis indicated that the pulmonary metastasis originated from the cholangiocarcinoma. Fifteen months after the pulmonary resection, another solitary pulmonary metastasis was detected in the left lower lobe. As the patient refused further chemotherapy, we performed stereotactic body radiotherapy(SBRT)(50 Gy/4 Fr). An adverse event of Grade 1 radiation pneumonitis was observed. The metastasis disappeared after SBRT. Twenty-eight months after SBRT and 70 months after the initial surgery, the patient is alive without recurrence.

RESUMEN

Pneumothorax induced by Pneumocystis jirovecii( P. jirovecii) pneumonia is often refractory to treatment. A man in his 30's who had malignant lymphoma and received chemotherapy developed P. jirovecii pneumonia. A month after treatment for pneumonia, he developed a secondary pneumothorax. Since drainage was not effective, he underwent right lower lobectomy and bulla resection. Air leakage stopped after surgery but recurred on postoperative day 5. Chest computed tomography showed a new bulla on his right lung. On postoperative day 15, we inserted an endobronchial Watanabe spigot( EWS),and air leakage completely stopped.

RESUMEN

Pulmonary hamartoma (PH) is the most common benign lung tumor, comprising various amounts of mescenchymal components with entrapped epithelial components. We describe an unusual case of PH in the left lower lung lobe of a 60-year-old female. The tumor was 9 × 9 mm in size, light brown, weakly glistening, and microscopically found to be composed of well-developed epithelial and mesenchymal components without atypia. Both components were intermingled but without apparent transition. Epithelial components were occupied by predominant bronchial mucous glands. Serous glands, entrapped bronchioles, and clefts lined by respiratory epithelium were also apparent. Mesenchymal components including cartilage and fat were scattered, and swirling smooth muscle fascicles were interlaced with epithelial components. Collision tumor or other biphasic tumors were unlikely, and hyperplastic change in bronchial glands as in the rare conditions of intraoral minor salivary glands and epithelial entrapments by PH may explain these interesting histological findings. It is important to be aware of the possibility that a large number of bronchial mucous glands may be noted in the peripheral lung, and not to mistake this for other malignancies.

RESUMEN

A primary desmoid tumor arising from the chest wall is extremely rare. We report the case of a 57-year-old man presenting with a desmoid tumor arising from his chest wall. Chest radiograph at a regular medical checkup indicated an abnormal shadow. By computed tomography-guided biopsy, he was diagnosed as having a desmoid tumor. He underwent right-sided chest wall resection and reconstruction. Desmoid tumor is histopathologically benign tumor, however, they tend to show high rates of local recurrence after surgery. In case of recurrence on unresectable case, radiotherapy or some medical treatment should be chosen as a treatment option.

RESUMEN

BACKGROUNDS: The neutrophil-lymphocyte ratio (NLR) is a simple and low-cost index that may be a benchmark for systemic inflammatory response and antitumor immunity. The goal of the study was to investigate the prognostic value of preoperative NLR in patients with lung adenocarcinoma after complete resection. METHODS: The subjects were 361 consecutive patients with lung adenocarcinoma who underwent complete resection between 2000 and 2009. Perioperative clinical and laboratory data were evaluated retrospectively. The cohort was divided using the cut-off value for preoperative NLR identified in receiver operating characteristic analysis. Correlations of NLR with clinicopathological characteristics and prognosis were examined. RESULTS: A high NLR was significantly correlated with a smoking history >10 pack-years (p = 0.023), pathological stage II or III (p < 0.001), lymphatic invasion (p = 0.003), and pleural invasion (p = 0.039). In univariate analysis, the high NLR group had significantly lower 5-year overall survival (86.0 vs. 77.1 %, p < 0.001) and 5-year recurrence-free survival (75.1 vs. 59.9 %, p < 0.001). Multivariate analysis showed that NLR was an independent prognostic factor (hazard ratio 1.822, 95 % confidence interval 1.133-2.931, p = 0.013). CONCLUSION: These results show that preoperative NLR is an independent prognostic factor in patients with lung adenocarcinoma after complete resection. NLR may reflect host immunity and systemic inflammation that facilitates tumor growth.

RESUMEN

INTRODUCTION: Pulmonary metastases are the most common among extrahepatic recurrences from hepatocellular carcinoma (HCC). It causes high risk of HCC-related death, despite recent progress in therapeutic options. However, a role of pulmonary metastasectomy as well as prognostic factors after metastasectomy has not been well established. We aimed to investigate survival outcomes and prognostic factors after pulmonary resection for metastases from HCC. METHODS: A series of 93 patients who underwent pulmonary resections for metastases from HCC between June 1990 and July 2013 from multi-institutional database were retrospectively evaluated. Perioperative clinicopathological data and their association with prognosis were investigated. RESULTS: Of 93 patients, 77 had one pulmonary metastasis, and 16 had two or more. Recurrence after pulmonary resection was noted in 60 patients (64.5 %). The estimated 5-year overall survival rate was 41.4 % with median survival time after pulmonary metastatectomy of 39.0 months. Univariate prognostic analysis showed that disease-free interval of ≥12 months was significantly associated with favorable outcomes in both overall survival (5-year rate, 59.3 vs. 28.7 %, p = 0.026) and disease-specific survival (5-year rate, 62.5 vs. 36.2 %; p = 0.038) after pulmonary metastatectomy. A multivariate analysis revealed that disease-free interval was an independent prognostic factor (HR = 2.020, 95 % CI, 1.069-3.816, p = 0.030). CONCLUSION: We have shown that a disease-free interval was an independent prognostic factor in patients who underwent pulmonary resection for metastasis from HCC. Also, pulmonary metastasectomy can be one of the therapeutic choices for select patients.

RESUMEN

BACKGROUND: Early detection of non-small-cell lung cancer (NSCLC) and accurate prognostic risk assessment could improve patient outcome. We examined the significance of urinary N(1), N(12)-diacetylspermine (DiAcSpm) in the detection and prognostic stratification of NSCLC patients. METHODS: A DiAcSpm/cutoff ratio (DASr) was established for 260 NSCLC patients, 99 benign lung disease patients, and 140 healthy volunteers, using colloidal gold aggregation methods. The DASr was compared between patients and healthy controls, and the prognostic significance of DASr was examined. RESULTS: The median urinary DASr of NSCLC patients was significantly higher than that of healthy controls (0.810 vs 0.534, P<0.001). The DASr was higher in squamous cell carcinoma (SqCC) patients than in adenocarcinoma patients (1.18 vs 0.756, respectively, P=0.039). An increased urinary DASr value was significantly associated with pathological stage, other histological invasive factors and unfavourable outcomes in patients with completely resected NSCLC. Multivariate Cox regression analysis showed that increased urinary DASr was an independent prognostic factor (hazard ratio=4.652, 95% confidence interval (CI), 2.092-10.35; P<0.001). CONCLUSIONS: Urinary DASr was significantly increased in NSCLC, especially in SqCC. Urinary DASr was an independent poor prognostic indicator in patients with completely resected NSCLC. The DASr could be a useful biomarker for detecting malignancies and predicting prognosis.

RESUMEN

BACKGROUND: The immune system has been shown to play an important role in preventing cancer progression. The neutrophil-lymphocyte ratio (NLR) has been proposed to be an indicator of a systemic inflammatory response. We investigated the prognostic significance of NLR in patients with completely resected stage I non-small lung cancer (NSCLC). METHODS: A series of 343 pathological stage I NSCLC patients, completely resected between 2000 and 2008 at a single institution, were evaluated retrospectively. Perioperative clinical and laboratory data were collected, and the cohort was divided into two groups according to preoperative NLR. We examined the correlation between NLR and clinicopathological parameters and determined the prognostic significance. RESULTS: High NLR was significantly correlated with patients of older age (p = 0.045), preoperative hypoalbuminemia (p = 0.030), and nonadenocarcinoma histology (p = 0.045). Upon univariate analysis, the high NLR group had significantly lower 5-year recurrence-free survival (81.2 vs. 59.9 %, p < 0.001) and 5-year overall survival (89.2 vs. 72.8 %, p < 0.001) than the low NLR group. Multivariate analysis showed that NLR was an independent prognostic factor (hazard ratio 2.141, 95 % confidence interval; 1.306-3.515, p = 0.003). In terms of initial recurrent sites, the proportion of patients who developed distant metastasis was significantly higher in the high NLR group than in the low NLR group (p < 0.001). CONCLUSIONS: Preoperative high NLR is a significant predictor of poor prognosis and is associated with more frequent distant metastasis in patients with completely resected stage I NSCLC. This readily available and simply calculated ratio provides useful information for the clinician to consider in terms of perioperative management.

RESUMEN

BACKGROUND: To select optimal candidates for limited lung resection, it is necessary to accurately differentiate the non-invasive tumors from other small-sized lung cancer. Urinary N(1), N(12)-diacetylspermine (DiAcSpm) has been reported to be a useful tumor marker for various cancers. We aimed to examine the correlation between preoperative urinary DiAcSpm levels and specific clinicopathological characteristics such as the histological tumor invasiveness in patients with clinical stage IA non-small cell lung cancer (NSCLC). METHODS: We defined non-invasive tumors as NSCLC showing no vascular invasion, lymphatic permeation, pleural invasion, or lymph node metastasis. Preoperative urine samples were obtained from 516 consecutive patients with NSCLC resected at our institution between April 2008 and January 2013. Urinary DiAcSpm values were determined for all preoperative urine samples using the colloid gold aggregation procedure. Among these patients, 171 patients with clinical stage IA NSCLC met the criteria of our study cohort. Finally, we investigated the correlation between non-invasive tumor and urinary DiAcSpm levels. RESULTS: The median urine DiAcSpm for males was 147.2 nmol/g creatinine and 161.8 nmol/g creatinine in females. These median values were set as the cut-off values for each gender. Patients with higher urinary DiAcSpm levels frequently had significantly elevated serum CEA (p = 0.023) and greater lymph node metastasis (p = 0.048), lymphatic permeation (p = 0.046), and vascular invasion (p = 0.010). Compared with patients with non-invasive tumors, patients with invasive tumors had a tumor size >2.0 cm (p = 0.001), serum CEA >5.0 mg/dL (p < 0.001), high urinary DiAcSpm (p = 0.002), and a tumor disappearance rate (TDR) <0.75 (p < 0.001). Multivariate analysis revealed that a tumor size < 2.0 cm (RR = 2.901, 95% CI; 1.372-6.136, p = 0.005), high urinary DiAcSpm (RR = 3.374, 95% CI; 1.547-7.361, p = 0.002), and TDR < 0.75 (RR = 4.673, 95% CI; 2.178-10.027, p < 0.001) were independent predictors for invasive tumors. CONCLUSIONS: We successfully showed that there was a significant correlation between urinary DiAcSpm levels and pathological tumor invasiveness in patients with clinical stage IA NSCLC. Further research would elucidate the clinical usefulness of DiAcSpm levels as a predictor of tumor invasiveness.

RESUMEN

BACKGROUND: Thymic epithelial tumors (TETs), which comprise thymoma and thymic carcinoma, are rare cancers with specific morphological and clinical features. Their clinical characteristics and outcomes have gradually been clarified by assessing large-scale, retrospective data obtained with international cooperation. METHODS: The study is a retrospective review of 187 Japanese patients with TETs who attended our institution from 1976 to 2012. Relevant clinical features of patients with TETs and their tumors, including histology, staging, treatment strategies, and overall survival, were investigated. Differences in survival were assessed by the Kaplan-Meier method and uni- and multi-variate Cox proportional hazards regression analyses. RESULTS: The 187 patients included 52 patients with stage I, 37 with stage II, 22 with stage III, and 76 with stage IVa/IVb tumors according to the Masaoka-Koga Staging System. As to histological type, five patients had type A, 33 type AB, 19 type B1, 39 type B2, and 15 type B3 thymomas, whereas 68 patients had thymic carcinoma, including 11 with neuroendocrine carcinomas according to the 2004 WHO classification. Either insufficient data were available to classify the tumors of the remaining eight patients or they had rare types. Immunological abnormalities were present in 26 patients, most of whom had thymomas (21.8% of the thymoma group). Most of the patients who presented with symptoms had myasthenia gravis or extensive thymic carcinoma. Secondary cancers were present in 25 patients (13.3%). The overall 5- and 10-year survival rates for thymoma were 85.4 and 71.5%, respectively, and those for thymic carcinoma were 33.8 and 2.3%, respectively. OS differed significantly between stage IVa thymomas and thymic carcinomas. The stage and whether the tumors were thymomas or thymic carcinomas were significant determinants of survival according to multivariate analysis. CONCLUSION: The efficacy of treatments for thymoma and thymic carcinoma should be investigated separately because these tumors differ in their clinical features and prognosis.

RESUMEN

Solitary papilloma of the lung is thought to be a rare benign epithelial tumor, and complete surgical resection is currently the standard treatment for this pathology. However, some cases of papilloma have reportedly shown malignant potential. We report two cases of solitary glandular papilloma of the peripheral lung that were treated by thoracoscopic partial resection. The first patient presented with a nodular lesion in the lower lobe of the left lung that was detected on a follow-up chest computed tomography (CT) scan after treatment for laryngeal cancer. Partial lung resection was performed by video-assisted thoracoscopic surgery. In the second patient, a nodular lesion was incidentally identified in the lower lobe of the left lung during a health check-up. Partial lung resection was again performed by video-assisted thoracoscopic surgery. The postoperative course in both cases was uneventful, and no recurrences have been observed as of 44 months and 41 months postoperatively, respectively. To the best of our knowledge, malignant transformation has been reported both with the squamous type and the mixed type of solitary papilloma of the lung. The glandular variant has shown no tendency toward local recurrence after local excision and has no apparent malignant potential. Local excision is thus recommended for solitary glandular papilloma in order to preserve pulmonary function.

RESUMEN

PURPOSE: Although life-threatening situations can be avoided using an open window thoracostomy (OWT), the closure is often difficult. We investigated the predictors of a successful closure of an OWT at the time of OWT creation. METHODS: Thirty-five consecutive patients who underwent an OWT at our institute between January 1991 and December 2010 were reviewed. We directly compared the patients with and without a successful OWT closure. A logistic regression analysis was employed to determine the predictive factors of a successful closure. RESULTS: OWT closure was only achieved in 12 patients. The closure of the OWT and absence of diabetes mellitus significantly influenced the survival of the OWT patients. The OWT in patients with preceding lung resection was difficult to close, especially if the underlying disease was lung cancer. The existence of a bronchopleural fistula (BPF) was not related to successful closure. Among the post-lung resection patients, the nutritional status tended to affect the success of the closure. CONCLUSION: Successful closure is difficult to predict at the time of the creation of an OWT. A comprehensive approach, including nutritional support and the precise timing of intervention is critical to promote a successful closure.

RESUMEN

A 43-year-old man presented with a pulmonary nodule in the left lower lobe and he consulted our hospital one year after resection of left adrenocortical carcinoma. We performed a wedge resection of the left lower pulmonary lobe for diagnosis. The tumor was diagnosed as a metastatic sarcoma, but the primary site could not be resolved. We assessed the histopathology of the adrenal tumor, which was obtained from the patient's former hospital, and it showed that the tumor consisted of both carcinomatous and sarcomatous components. This enabled us to diagnose the nodule as a pulmonary metastasis from the adrenocortical carcinoma. Adrenocortical carcinoma with a sarcomatous component is very rare. This case is a first report of a resected pulmonary metastasis of sarcomatous component of adrenocortical carcinoma.

RESUMEN

Spontaneous regression (SR) of thymoma is rare. We report a case of a surgically resected thymoma due to cystic changes owing to acute ischemic infarction with an increased anti-acetylcholine receptor antibody level. A 61-year-old male underwent a computed tomography (CT) scan, which showed a 4.9 cm anterior mediastinal tumor and slight right pleural effusion. Blood test results indicated an elevated white blood cell count of 13300/mL. One month later, an enhanced CT scan at our hospital showed spontaneous mediastinal tumor regression to 3.7 cm and no pleural effusion. The tumor contained homogeneous low-density areas on enhanced CT, which showed high intensity on T2-weighted magnetic resonance imaging, indicating cystic changes. He had no symptoms of myasthenia; however, his anti-acetylcholine receptor antibody level was slightly elevated (0.4 nmol/L). Suspecting a thymoma, an extended total thymectomy through a median sternotomy was performed. Histopathological analysis confirmed the diagnosis of thymoma type B2 and Masaoka stage I. SR is due to acute intratumoral infarction. At two years postoperatively, no tumor recurrence or development of myasthenia gravis was observed. Thymomas should be included in the differential diagnosis of anterior mediastinal tumors that regress spontaneously with cystic changes, pleural effusion, and an elevated inflammatory response. Mature cystic teratoma rupture should be differentiated, but preoperative biopsy is often challenging owing to necrotic and fibrous tissues; therefore, early surgical resection is required for diagnosis and treatment.

RESUMEN

The features of intralobar pulmonary sequestration vary on computed tomography (CT). Many cases demonstrate a mass or cystic lesion within a lower lobe. We report herein a case of a 55-year-old, female patient presenting with right back pain. Contrast enhanced (CE) CT revealed multiple, nodular, pulmonary lesions suggesting recurrent infections with surrounding focal emphysema. Three-dimensional (3D) reconstruction demonstrated a sequestrated lung segment with a systemic, arterial blood supply. Based on these findings, intralobar pulmonary sequestration was diagnosed. Intralobar pulmonary sequestration can present as multiple, nodular, pulmonary lesions with focal emphysema rather than as a mass or cyst. CE-CT with 3D reconstruction is useful for diagnosing this condition. Patients with recurrent pulmonary infections have a high index of suspicion of intralobar pulmonary sequestration.

RESUMEN

OBJECTIVE: We aimed to identify prognostic factors after pulmonary metastasectomy for colorectal cancer and propose the clinical application of them. Furthermore, we endeavored to provide a rationale for pulmonary metastasesectomy. BACKGROUND: Several prognostic factors have been proposed, but clinical application of them remains unclear. Moreover, there is no theoretical evidence that pulmonary metastasectomy is indicated for colorectal cancer. METHODS: We retrospectively analyzed 1030 patients who underwent pulmonary metastasectomy for colorectal cancer from 1990 to 2008. Prognostic factors were identified and the relationship of recurrent sites after pulmonary resection to pulmonary tumor size was assessed. RESULTS: Overall 5-year survival was 53.5%. Median survival time was 69.5 months. Univariate analysis showed tumor number (P < 0.0001), tumor size (P < 0.0001), prethoracotomy serum carcinoembryonic antigen (CEA) level (P < 0.0001), lymph node involvement (P < 0.0001), and completeness of resection (P < 0.0001) to significantly influence survival. In multivariate analysis, all remained independent predictors of outcome. In patients whose recurrent sites extended downstream from the lung via hematogenous colorectal cancer spread, pulmonary tumor size was significantly larger than in those with recurrent sites confined to the lung and regions upstream from the lung. CONCLUSIONS: We should utilize these prognostic factors to detect patients who might benefit from surgery. Therefore, we should periodically follow up advanced colorectal cancer patients by chest computed tomography to detect small pulmonary metastases before serum CEA elevation. Metastases to the lung or organs upstream from the lung are regarded as semi-local for colorectal cancer. This concept provides a rationale for validating surgical indications for pulmonary metastases from colorectal cancer.

RESUMEN

We report a rare case of fibrosing mediastinitis diagnosed by thoracoscopic biopsy. A 56-year-old female visited our hospital with an abnormal mediastinal shadow on chest X ray. Chest computed tomography revealed a paravertebral tumor from Th9 to Th11. Pathological examination of thoracoscopic biopsy specimen showed fibrous tissue with mild inflammation and no malignant feature. Final diagnosis was idiopathic fibrosing mediastinitis. The paravertebral lesion shrinked spontaneously 5 months later after biopsy.

RESUMEN

Cholesterol granulomas of the thymus are extremely rare benign entities. Herein, we describe a case of cholesterol granuloma in a 45-year-old man who presented with multifocal anterior mediastinal lesions on computed tomography (CT). Positron emission tomography (PET)-CT revealed increased fluorodeoxyglucose uptake, with a maximum standardized uptake value of 8.3. Diffusion-weighted magnetic resonance imaging (MRI) revealed extreme hypointensity. He underwent total thymectomy by median sternotomy for presumed multiple thymoma. On histopathological analysis, cholesterol granuloma of the thymus was confirmed, and the patient had an uneventful postoperative course without recurrence for 28 months. Cholesterol granuloma of the thymus is a PET-CT-positive benign tumor with unique histological findings. The MRI findings were indicative of hypocellularity associated with a benign entity, whereas the PET-CT findings corresponded to granulomatous inflammation. Therefore, concurrent use of PET-CT and MRI can be helpful in distinguishing between benign cholesterol granulomas and malignant anterior mediastinal tumors.

RESUMEN

Combined thoraco-laparoscopic resection can aid in precise resection of an invasive tumor of the diaphragm. A 44-year-old woman was referred to our department for resection of solitary peritoneal seeding from cervical cancer following systemic chemotherapy. The tumor was located in the right diaphragm with an ill-defined border of the liver. Combined thoraco-laparoscopic resection was proposed. Laparoscopy portrayed that the right diaphragm was partially attached to the liver, and the depth of tumor invasion to the diaphragm was ambiguous. Observation from the thoracic cavity indicated a white-colored distortion following the location of peritoneal seeding. Partial resection and repair of the diaphragm were made using the thoracoscopic-assisted approach, followed by laparoscopic hepatectomy. The postoperative course was uneventful, and pathological findings revealed that peritoneal metastases of the diaphragm and surgical margin was negative for cancer. Combined thoraco-laparoscopic resection can cover the drawbacks of each approach and is among the options for minimally invasive surgery for invasive tumor of the diaphragm.
