    Every patient undergoing curative treatment for primary lung cancer is a candidate for metachronous lung cancer, with a reported risk of 5% per year. The majority of cases are stage I patients. Patients who undergo resection for lung cancer should be followed regularly. A metachronous lung cancer that develops as bilateral synchronous lung cancer is very rare.

  2. Lung cancer: assessing resectability

    Staging classification in patients with non-small cell lung cancer does not always correlate perfectly with surgical resectability. Therefore, it is important to evaluate individual features of a patient’s tumor in order to determine if surgical resection is the optimal method of treatment, regardless of tumor stage. Such features include characteristics of the primary tumor, regional lymph nodes and distant sites.

  3. Assessing resectability of lung cancer

    International Nuclear Information System (INIS)

    In order to assess the value of computed tomography (CT) of the mediastinum, upper abdomen and head in the assessment of resectability of lung cancer, the CT findings of 262 patients, of whom 198 underwent thoracotomy, were anlyzed retrospectively and the stagings obtained at CT and thoracotomy were compared. Mediastinal CT reliably predicted resectability when there was no evidence of mediastinal involvement. However, it was often impossible to determine whether tumour with apparent mediastinal infiltration on CT was resectable or not. The sole finding of lymph node enlargement did not permit differentiation of benign from malignant lymphadenopathy when the lymph node diameter as < 25 mm and the lymphadenopathy was confined to one lymph node station. Upper abdominal metastases were found in 6.1% and brain metastases in 4.6% of patients and neither the histological type nor other features of the tumour were found to be useful predictors of their presence. The large number of non-specific findings decreased the utility of abdominal CT. The appropriate strategy for the pre-operative evaluation of patients with lung cancer is discussed.

    BACKGROUND—Surgical resection is the recognised treatment of choice for patients with stage I or II non-small cell lung cancer (NSCLC). In the UK surgical resection rates have remained far lower (20%), despite the recent introduction of fast access investigation units. It remains unclear therefore why UK surgical resection rates lag so far behind those of other countries.

    Full Text Available Aim: Pediatric lung resection is a relatively uncommon procedure that is usually performed for congenital lesions. In recent years, thoracoscopic resection has become increasingly popular, particularly for small peripheral lesions. The aim of this study was to review our experience with traditional open lung resection in order to evaluate the existing "gold standard." Materials and Methods: We carried out a retrospective analysis of all children having lung resection for congenital lesions at our institution between 1997 and 2004. Data were collected from analysis of case notes, operative records and clinical consultation. The mean follow-up was 37.95 months. The data were analyzed using SPSS. Results: Forty-one children (13 F/28 M underwent major lung resections during the study period. Their median age was 4.66 months (1 day-9 years. The resected lesions included 21 congenital cystic adenomatoid malformations, 14 congenital lobar emphysema, four sequestrations and one bronchogenic cyst. Fifty percent of the lesions were diagnosed antenatally. Twenty-six patients had a complete lobectomy while 15 patients had parenchymal sparing resection of the lesion alone. Mean postoperative stay was 5.7 days. There have been no complications in any of the patients. All patients are currently alive, asymptomatic and well. None of the patients have any significant chest deformity. Conclusions: We conclude that open lung resection enables parenchymal sparing surgery, is versatile, has few complications and produces very good long-term results. It remains the "gold standard" against which minimally invasive techniques may be judged.

  6. Assessing non-resectability of lung cancer

    International Nuclear Information System (INIS)

    To investigate whether the assessment of resectability of lung cancer can be reliably made on the basis of computed tomography (CT), the thoracic CT scans of 96 lung cancer patients who were operated on, and in whom the tumour was classified to be of stage III at preoperative CT or at thoracotomy, were analysed. Of the patients, 58 underwent complete resection of the tumour, whereas thoracotomy resulted in non-complete resection or exploration only in 38 cases. Overlapping of the CT findings in the groups of complete and non-successful resection was observed. The majority of tumours with apparent growth to the carina, trachea, oesophagus or great vessels at CT were completely resected. Tumours that only bordered on the pleura could not be distinguished from those with pleural invasion. Mediastinal lymph node enlargement did not always mean metastatic spread. We conclude that there is no definite sign that identifies non-resectability of lung tumours, and a certain proportion of non-curative thoracotomies must be accepted. (orig.)

    Full Text Available Objective. Improve the effectiveness of surgical treatment in patients with bilateral destructive pulmonary tuberculosis by mini-invasive resection and collapse therapy. Materials and Methods: Retrospective analysis of 222 patients’ cards with bilateral destructive pulmonary tuberculosis who were treated in the period from 1995 to 2014 in the thoracic department of Dnepropetrovsk regional clinical therapeutic and prophylactic association "Phthisiology". Patients were divided into 2 groups: basic (111 patients who underwent mini-invasive surgery and control (111 patients, who underwent standard surgical approach. The distribution of patients in investigated groups was representative by the majority of parameters. Results and discussion. The average duration of simultaneous bilateral VATS lung resections was 1,90 ± 0,12 hour, standard thoracotomies - 2,13 ± 0,19 per hour, estimated blood loss was 234±5,20ml and 433±3,70ml respectively. The average postoperative time in-patient was 52,40±2,63 days in basic and 80,10±3,58 days in the control group. Number of postoperative complications after lung resection with VATS was significantly lower (1.6 times, as compared with standard surgical approach. Volume of blood loss less than 400 ml was 93,40±3,20% in basic and 72,60±4,80% in the control group, the amount of intraoperative complications reduced by 2.2 times. Complete clinical response (decontamination and closing of cavities have been achieved in patients of the basic group by 1.6 times more often. Conclusions: For patients with bilateral pulmonary tuberculosis to perform mini-invasive surgical approach is the best option. Mini-invasive interventions with VATS due to its good abilities to visualize tissues and anatomical structures may significantly decrease the amount of intraoperative blood and plasma loss in the first postoperative day. It leads to the stabilization of tuberculosis process in the contralateral lung, responsible for

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

    Full Text Available We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.

    There is sparse information concerning approaches to metachronous lung cancer in patients who had a previous pneumonectomy for lung carcinoma. We describe the case of a 55-year-old woman who underwent a left pneumonectomy for lung carcinoma. Four years later, a radiological examination revealed a hypermetabolic nodule in the right upper lobe, which was located in the left hemithorax because of right lung hyperinflation and a mediastinal shift to the left. Wedge resection was carried out through a left anterior mediastinotomy. We believe that an anterior mediastinotomy represents a valuable option for the management of recurrent lung cancer after previous surgery. PMID:26124429

  12. Prediction of postoperative pulmonary reserve in lung resection patients

    International Nuclear Information System (INIS)

    We performed Ventilation/Perfusion scans for patients planned for thoracotomy with resection of the primary or metastatic lung tumors. We predicted the post-operative FEV1 (Forced Expiratory Volume in first second) using Differential Lung Analysis software. Methods: 34 patients were evaluated with Ventilation/Perfusion (V/Q) scans. Ventilation scan was performed with Tc-99m DTPA Aerosol and Perfusion Scan with Tc99m MAA, on 2 different days. The numbers of counts in anterior and posterior views of V/Q scans were calculated individually. Anterior and posterior arithmetical mean was calculated and post-operative FEV1 was predicted with the use of Differential Lung Analysis software. In most of the patients, the counts in the ventilation scan were lower and they were related to preoperative FEV1. Depending on the volume of lung resection, i.e. Upper, Middle and Lower zones or Total Pneumonectomy, FEV1 was calculated. Whenever FEV1 was >0.8 (L), the patient was taken up for resection (and if there were no other risk factors, such as cardiac complications, chronic obstructive pulmonary diseases, and any other pathological conditions involving the contralateral lung). Results: Most of the 34 patients were taken up for lung resection based on our FEV1 predictions. In 7 patients, repeat spirometry (i.e. pulmonary function test) was done at varying intervals after surgical procedures and the variation between preoperative FEV1 and postoperative FEV1 was only ± 15%, at the most. Conclusion: Postoperative FEV1 based on V/Q scan and pulmonary function tests helped us to proceed with lung resection after assessment of the pulmonary reserve. (authors)

    Full Text Available OBJECTIVE: The aim of this study is to determine clinical, pathological, and treatment-relevant variables associated with long-term (90-month overall survival in patients with lung metastases undergoing pulmonary metastasectomy. METHODS: A retrospective review was performed of patients who were admitted with lung metastases, and who underwent thoracotomy for resection, after treatment of a primary tumor. Data were collected regarding demographics, tumor features, treatment, and outcome. RESULTS: Patients (n = 529 were submitted to a total of 776 thoracotomies. Median follow-up time across all patients was 21.6 months (range: 0-192 months. The postoperative complication rate was 9.3%, and the 30-day mortality rate was 0.2%. The ninety-month overall survival rate for all patients was 30.4%. Multivariate analysis identified the number of pulmonary nodules detected on preoperative CT-scan, the number of malignant nodules resected, and complete resection as the independent prognostic factors for overall survival. CONCLUSION: These results confirm that lung metastasectomy is a safe and potentially curative procedure for patients with treated primary tumors. A select group of patients can achieve long-term survival after resection.

  17. Changes of left ventricular function at exercise after lung resection

    International Nuclear Information System (INIS)

    To determine the effect of lung resection on left ventricular function, 29 surgical patients were examined by using a nuclear stethoscope as a non-invasive means for measuring ventricular function at exercise. Pre- and post-operative parameters were obtained at rest and exercise. At rest, postoperative stroke volume (SV), end-diastolic volume (EDV), ejection fraction (EF), and ejection rate (ER) were significantly decreased; heart rate (HR) was significantly increased; and both filling rate (FR) and cardiac output (CO) remained unchanged. At maximum exercise, postoperative EDV, SV, ER and FR were significantly decreased; and there was no significant difference in either HR or EF, resulting in a significantly decreased CO. A ratio of CO and FR at maximum exercise to at rest was significantly decreased after surgery, as compared with that before surgery. According to the number of lobe resection, similar findings for all parameters, except for EF, were observed in the group of two lobe or more resection (n=13); and only two parameters, ER and FR, had the same tendency as those mentioned above in the group of a single lobe resection (n=16). The age group of 60 years or less (n=14) had similar findings for all parameters. In the group of 65 years or more (n=10), resting HR after surgery was not different from that before surgery; and postoperative CO was significantly decreased at rest, but not different from preoperative value at maximum exercise. In conclusion, left ventricular function associated with lung resection is reflected by decreased EDV and SV resulting from reduced pre-load. These changes may be corrected at rest, but not corrected at maximum exercise, resulting in decreased CO. More noticeable decrease in EDV and SV seems to be associated with larger lung resection. In older patients, HR is not corrected well, resulting in a decrease in CO at rest. (N.K.)

    Physiotherapy is considered an important component of the perioperative period of lung resection surgery. A systematic review was conducted to assess evidence for the effectiveness of different physiotherapy interventions in patients undergoing lung cancer resection surgery. Online literature databases [Medline, the Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, SCOPUS, PEDro and CINAHL] were searched up until June 2013. Studies were included if they were randomized controlled trials, compared 2 or more perioperative physiotherapy interventions or compared one intervention with no intervention, included only patients undergoing pulmonary resection for lung cancer and assessed at least 2 or more of the following variables: functional capacity parameters, postoperative pulmonary complications or length of hospital stay. Reviews and meta-analyses were excluded. Eight studies were selected for inclusion in this review. They included a total of 599 patients. Seven of the studies were identified as having a low risk of bias. Two studies assessed preoperative interventions, 4 postoperative interventions and the remaining 2 investigated the efficacy of interventions that were started preoperatively and then continued after surgery. The substantial heterogeneity in the interventions across the studies meant that it was not possible to conduct a meta-analysis. The most important finding of this systematic review is that presurgical interventions based on moderate-intense aerobic exercise in patients undergoing lung resection for lung cancer improve functional capacity and reduce postoperative morbidity, whereas interventions performed only during the postoperative period do not seem to reduce postoperative pulmonary complications or length of hospital stay. Nevertheless, no firm conclusions can be drawn because of the heterogeneity of the studies included.

  20. Prediction of postoperative lung function after pulmonary resection

    International Nuclear Information System (INIS)

    Lung scintigraphy and ordinary lung function test as well as split lung function test by using bronchospirometry was performed in 78 patients with primary lung cancer and clinical significance of ventilation and perfusion scintigraphy was evaluated. Results obtained from this study are as follows. 1) The ratio of right VC to total VC obtained by preoperative bronchospirometry was well correlated to the ratio of right lung count to the total lung count obtained by ventiration and/or perfusion scintigraphy (r = 0.84, r = 0.69). 2) Evaluation of the data obtained from the patients undergoing pneumonectomy indicated that the right and left VC obtained preoperatively by bronchospirometry have their clinical significance only in the form of left to right ratio not in the form their absolure value. 3) As to the reliability of predicting the residual vital capacity after pneumonectomy on the basis of left-to-right of lung scintigraphy, ventilation scintigraphy is more reliable than perfusion scintigraphy. 4) Irrespective of using ventilation scintigraphy or perfusion scintigraphy, Ali's formular showed high reliability in predicting the residual vital capacity as well as FEV1.0 after lobectomy. 5) Reduction of the perfusion rate in the operated side of the lung is more marked than of the ventilation rate, resulting in a significant elevation of ventilation/perfusion ratio of the operated side of the lung. From the results descrived above, it can be said that lung ventilation and perfusion scintigraphy are very useful method to predict the residual lung function as well as the change of ventilation/perfusion ratio after pulmonary resection.

Rather, she was treated presumptively for Wilms tumor based primarily on radiologic findings. Neoadjuvant chemotherapy consisting of vincristine, dactinomycin and doxorubicin was given to facilitate nephron-sparing surgery for tumor resection. Her initial chemotherapeutic course was complicated by tumor lysis syndrome manifested by elevated serum uric acid and was treated effectively with hyperhydration and alkalization of intravenous fluids. The patient's disease responded well to chemotherapy, and she underwent successful tumor excision after 12 weeks of chemotherapy. The resected tumor was identified as anaplastic Wilms tumor, illustrating that pathologic identification of Wilms tumor is possible even after multiple cycles of neoadjuvant chemotherapy and marked tumor shrinkage.

    An analysis of results of surgical treatment of 28 patients with lung cancer who underwent resection of the left atrium has shown that squamous cell cancer was diagnosed in 18 patients (64%), adenocarcinoma--in 5 (18%), dimorphous cancer--in 2 (7%), mucoepidermoid cancer in 2 (7%), atypical carcinoid--in 1 patient (4%). The degree of regional lymphogenic spread of the tumor NO took place in 11 patients (39%), N1--in 6 patients (22%), N2--in 11(39%). True invasion of the tumor to the left atrium myocardium took place in 20 patients (71%), involvement of the pulmonary vein orifices in the tumor process--in 8 (29%). Resection of the atrium was made using mechanical suturing apparatuses. The right side resections were fulfilled in 16 patients (57%), left side resections in 12 patients (43%). Pneumonectomy was fulfilled in 26 patients (93%), lobectomy--in 2 patients (7%). The operative interventions in five cases (18%) were estimated as microscopically non-radical (R1). The average time in the intensive care unit after operation was 3 days (from 1 till 12), in the surgical thoracal department--18 days (from 13 till 37). In the early postoperative period one patient died (4%), complications were noted in 5 patients (18%). The total one year survival was 69%, three year survival--39%, 5 year survival--17%. The survival median was 23 months. Resection of the left atrium in the selected lung cancer patients was not followed by growing operative lethality and the acceptable long term results were obtained. PMID:18050636

    Robotic-assisted pulmonary lobectomy can be considered for patients able to tolerate conventional lobectomy. Contraindications to resection via thoracotomy apply to patients undergoing robotic lobectomy. Team training, familiarity with equipment, troubleshooting, and preparation are critical for successful robotic lobectomy. Robotic lobectomy is associated with decreased rates of blood loss, blood transfusion, air leak, chest tube duration, length of stay, and mortality compared with thoracotomy. Robotic lobectomy offers many of the same benefits in perioperative morbidity and mortality, and additional advantages in optics, dexterity, and surgeon ergonomics as video-assisted thoracic lobectomy. Long-term oncologic efficacy and cost implications remain areas of study. PMID:27261913

    Small cell lung cancer (SCLC) often presents with either regional or systemic metastases, but approximately 4% of patients present with a solitary pulmonary nodule. Surgical resection can be an option for these patients and is endorsed by the National Comprehensive Cancer Network (NCCN) guidelines. There are no prospective randomized clinical trials evaluating the role of adjuvant systemic therapy in these resected SCLC patients. A recent National Cancer Database analysis found that the receipt of adjuvant chemotherapy alone [hazard ratio (HR), 0.78; 95% CI, 0.63-0.95] or with brain radiation (HR, 0.52; 95% CI, 0.36-0.75) was associated with significantly improved survival as compared to surgery alone. As it is unlikely that a randomized prospective clinical trial addressing this question will be completed, these data should assist with decision making in these patients. PMID:27620199

We report a case of left lower lobe torsion in a 76-year-old female following elective upper lobectomy for underlying lung adenocarcinoma. Diagnosis was made following highly suggestive radiographic findings prompting bronchoscopy and revision thoracotomy. An emergency detorsion failed to restore lung viability and was followed by completion pneumonectomy. The patient recovered and was discharged on the seventh postoperative day.

    Lobar torsion is a fatal but fortunately rare occurrence following lung resection. Early clinical signs and radiographic features may be nonspecific resulting in diagnostic delay. A high index of suspicion is vital for early diagnosis and intervention to avoid further parenchymal necrosis and deadly gangrene.

    Accurate post-operative prognostication and management heavily depend on pathologic nodal stage. Patients with nodal metastasis benefit from post-operative adjuvant chemotherapy, those with mediastinal nodal involvement may also benefit from adjuvant radiation therapy. However, the quality of pathologic nodal staging varies significantly, with major survival implications in large populations of patients. We describe the quality gap in pathologic nodal staging, and provide evidence of its potential reversibility by targeted corrective interventions. One intervention, designed to improve the surgical lymphadenectomy, specimen labeling, and secure transfer between the operating theatre and the pathology laboratory, involves use of pre-labeled specimen collection kits. Another intervention involves application of an improved method of gross dissection of lung resection specimens, to reduce the inadvertent loss of intrapulmonary lymph nodes to histologic examination for metastasis. These corrective interventions are the subject of a regional dissemination and implementation project in diverse healthcare systems in a tri-state region of the United States with some of the highest lung cancer incidence and mortality rates. We discuss the potential of these interventions to significantly improve the accuracy of pathologic nodal staging, risk stratification, and the quality of specimens available for development of stage-independent prognostic markers in lung cancer.

    Backgrounds/Aims Aggressive surgical resection for hepatic metastasis is validated, however, concomitant liver and lung metastasis in colorectal cancer patients is equivocal. Methods Clinicopathologic data from January 2008 through December 2012 were retrospectively reviewed in 234 patients with colorectal cancer with concomitant liver and lung metastasis. Clinicopathologic factors and survival data were analyzed. Results Of the 234 patients, 129 (55.1%) had synchronous concomitant liver and lung metastasis from colorectal cancer and 36 (15.4%) had metachronous metastasis. Surgical resection was performed in 33 patients (25.6%) with synchronous and 6 (16.7%) with metachronous metastasis. Surgical resection showed better overall survival in both groups (synchronous, p=0.001; metachronous, p=0.028). In the synchronous metastatic group, complete resection of both liver and lung metastatic lesions had better survival outcomes than incomplete resection of two metastatic lesions (p=0.037). The primary site of colorectal cancer and complete resection were significant prognostic factors (p=0.06 and p=0.003, respectively). Conclusions Surgical resection for hepatic and pulmonary metastasis in colorectal cancer can improve complete remission and survival rate in resectable cases. Colorectal cancer with concomitant liver and lung metastasis is not a poor prognostic factor or a contraindication for surgical treatments, hence, an aggressive surgical approach may be recommended in well-selected resectable cases.

  16. Effect of lung resection on regional lung function assessed by 133Xe radiospirometry

    International Nuclear Information System (INIS)

    The regional lung function of 39 patients, 19 with lung cancer and 20 with a non-malignant condition, was studied radiospirometrically before partial lung resection and 2.6 and 12 months postoperatively. Dynamic spirometry was also performed at each stage. Initially, the postoperative reduction of total FEV1 was 19% and of VC 18%. There was 26% reduction of unilateral ventilation. 34% of perfusion and 30% of VC at two months post-operatively. At six months there was significant improvement in all parameters, whereas at twelve months there was no further notable change with the exception of total VC. At twelve months the reduction of FEV1 was 14% and of VC 8%. The unilateral perfusion was reduced 30%, ventilation 19%, and VC 17%. The V/Q ratio was 1.00 preoperatively and 1.11 12 months post-operatively. The results show that the final reduction of both unilateral and total function caused by partial lung resection is smaller than would be expected considering the anatomical extent of the operation. However, the V/Q mismatch ensuing from the operation may increase the functional impairment. Lung function appears to become stabilized at its permanent postoperative level during the first six months after operation. (orig.)

    Ventilation and perfusion lung scans were performed in 58 patients before operation for bronchial carcinoma to determine in which patients the lung scan was most useful for assessing mediastinal spread and resectability of the tumour. Perfusion of the affected lung was less with larger and more centrally situated tumours. Perfusion was also less for left-sided than for right-sided tumours but this is explained by the normal differential perfusion of the right and left lungs. The lung scan was...

    Full Text Available Bilateral hydatid cyst of lung in a child is a challenge to anaesthesiologist. The benefits of one lung versus two lung ventilation is still a question. A 9-yr-old male child presented with respiratory distress. The chest X-ray showed the presence of two cysts bilaterally in the lung fields. A possibility of bilateral hydatid cyst in lung was considered. The child was taken up for emergency single stage bilateral thoracotomy under general anaesthesia. Two lung ventilation technique was used. Postoperatively the child was kept on controlled ventilation in the paediatric intensive care unit. The child was weaned off from ventilatory support and extubated 48 hours after the surgery.

    Full Text Available To investigate the feasibility of thoracoscopic resection, a pilot study was performed in patients with clinically resectable lung tumors. In 40 patients, Video-assisted thoracic surgery (VATS was performed because of suspicion of malignancy. There were 29 men and 11 women with a median age of 54.8 years (range 18 to 78. Preoperative indications were suspected lung cancer and tumor in 27 patients, assessment of tumor resectability in 7 patients, and probability of metastatic tumors in 6 patients. The final diagnoses in the 27 patients with suspected lung cancer were 12 primary lung cancers, 6 lung metastases, and 9 benign lesions. The success rates for VATS (no conversion to thoracotomy were 1 of 12 (8.3% for resectable stage I lung cancer, 8 of 12 (66.7% for metastatic tumors, and 9 of 9 (100% for benign tumors. With VATS, 6 of 7 patients (85.7%, possible stage III non-small cell lung cancer, an explorative thoracotomy with was avoided, significantly reducing morbidity. The reasons for conversion to thoracotomy were 1 oncological (N2 lymph node dissection and prevention of tumor spillage and 2 technical (inability to locate the nodule, central localization, no anatomical fissure, or poor lung function requiring full lung ventilation. The ultimate diagnoses were 19 lung cancers, 12 metastatic lung tumors, and 9 benign lung tumors. Our data show the limitations of VATS for malignant tumors in general use. These findings, together with the fact that experience in performing thoracoscopic procedures demonstrates a learning curve, may limit the use of thoracoscopic resection as a routine surgical procedure, especially when strict oncological rules are respected.

  2. Anaesthesia for Lung Volume Reduction Surgery in Bilateral Bullous Lung Disease: A Case Report

    2008-01-01

    Full Text Available Lung Volume Reduction Surgery (LVRS has become an accepted modality for chronic pulmonary emphy-sema. Bilateral involve excision of emphysematous alveoli, which results in a 20% to 30% reduction in the volume of each lung. The goal of LVRS is to improve the respiratory mechanics in severe emphysema by re-expanding func-tional lung tissue that has been compressed by over-distended emphysematous alveoli, thus restoring diaphragmatic mobility and improving the bellows function of the chest wall structures. Anaesthesia for LVRS is a significant challenge to the anaesthetist as a result of high risk patient population and the nature of surgery. Management requires good understanding of the pathophysiology of the disease and surgical procedure. Close co-ordination be-tween the anaesthetist, surgeon and other support staff are of paramount importance.

    Full Text Available Heterotopic pregnancy is the simultaneous occurrence of two or more implantation sites. A 25-year-old infertile patient with a history of bilateral salpingectomy, uterine septum resection, and left cornual resection was diagnosed with heterotopic pregnancy in her second in vitro fertilization trial. She attended our clinic when she was 7-week pregnant, complaining initially of severe abdominal pain. Findings associated with peritoneal irritation were positive during the physical examination. Transvaginal ultrasound revealed right cornual ectopic pregnancy with a live fetus in the middle of the uterine cavity. Also free fluid was noted in the pelvis. A diagnosis of heterotopic pregnancy with rupture of the cornual pregnancy was made. She underwent emergency laparoscopy with aspiration of the ruptured ectopic pregnancy, suturing to the entire visible cornual margins, and assurance of good haemostasis. Her recovery was uneventful and she continued receiving care in our obstetric unit. She delivered a healthy newborn by cesarean section at term.

    Full Text Available The use of sublobar resections as definitive management in stage I non-small cell lung carcinoma is a controversial topic in the medical community. We intend to report the latest developments and trends in relative indications for each of the above-mentioned surgical approaches for the treatment of stage I non-small cell lung carcinoma as well as the results of studies regarding local recurrence, disease-free survival and five-year survival rates. We reviewed 45 prospective and retrospective studies conducted over the last 25 years listed in the Pubmed and Scopus electronic databases. Trials were identified through bibliographies and a manual search in journals. Authors, citations, objectives and results were extracted. No meta-analysis was performed. Validation of results was discussed. Segmentectomies are superior to wedge resections in terms of local recurrences and cancer-related mortality rates. Sublobar resections are superior to lobectomy in preserving the pulmonary parenchyma. High-risk patients should undergo segmentectomy, whereas lobectomies are superior to segmentectomies only for tumors >2 cm (T2bN0M0 in terms of disease-free and overall 5-year survival. In most studies no significant differences were found in tumors <2 cm. Disease-free surgical margins are crucial to prevent local recurrences. Systematic lymphadenectomy is mandatory regardless of the type of resection used. In sublobar resections with less thorough nodal dissections, adjuvant radiotherapy can be used. This approach is preferable in case of prior resection. In pure bronchoalveolar carcinoma, segmentectomy is recommended. Sublobar resections are associated with a shorter hospital stay. The selection of the type of resection in T1aN0M0 tumors should depend on characteristic of the patient and the tumor. Patient age, cardiopulmonary reserve and tumor size are the most important factors to be considered. However further prospective randomized trials are needed to

    In order to detect and track a small magnet embedded in the vicinity of a target tumor during surgery, we have developed a magnetic navigation system based on three-dimensional measurements with micro-fluxgate magnetic sensors. In this paper, we present an image overlay method for superimposing the embedded magnetic marker through a bronchoscope. To evaluate the performance of the proposed system and its applicability in clinical use, we set up an in vivo experiment, in which surgeons used this system to perform thoracoscopic surgery on a pig with transbronchial marking and oblique-viewing, and we succeeded in a partial resection of the pig lung including the target area. Next, we tried a wedge resection for a lung tumor in a clinical case. We successfully performed the partial resection of the lung including the target area, which corresponded to the tumor lesion, under the guidance of the magnetic navigation system.

    During one-lung ventilation (OLV) in the lateral position, the dependent, ventilated lung receives more blood flow than the non-dependent, non-ventilated lung owing to gravity, improving the match of ventilation and perfusion. Conversely, in the rare clinical situations when OLV is applied to the non-dependent lung, arterial oxygenation can get worse due to considerable shunt flow to the dependent non-ventilated lung. We report a case of severe hypoxemia during carinal resection under OLV of a non-dependent lung. In this case, OLV had to be applied to the non-dependent lung in the lateral position because the bronchus of the non-dependent lung was anastomosed with the trachea, whereas the bronchus of the dependent lung had already been resected for carinal resection. The subsequent hypoxemia resulting from the shunt flow to the dependent non-ventilated lung was treated successfully by ligating the pulmonary artery of the dependent lung. PMID:27274375

    The objective of this study was to assess the residual quality of life (QoL) in elderly patients submitted to major lung resection for lung cancer. From July 2004 through August 2007 a total of 218 patients, 85 of whom were elderly (70 years), had complete preoperative and postoperative (3 months) quality of life measures assessed by the Short Form 36v2 health survey. QoL scales were compared between elderly and younger patients. Furthermore, limited to the elderly group, we compared the preoperative with the postoperative SF36v2 measures and the physical component summary (PCS) and mental component summary (MCS) scores between high-risk patients and low-risk counterparts. The postoperative SF36 PCS (50.3 vs. 50, P=0.7) and MCS (50.6 vs. 49, P=0.2) and all SF36 domains did not differ between elderly and younger patients. Within the elderly, the QoL returns to the preoperative values three months after the operation. Moreover, we did not find any significant differences between elderly higher-risk patients and their lower-risk counterparts postoperatively. The information that residual QoL in elderly patients will be similar to the one experienced by younger and fitter individuals may help them in their decision to proceed with surgery. PMID:18940832

    The International Association for the Study of Lung Cancer, American Thoracic Society, and European Respiratory Society (IASLC/ATS/ERS) proposed a new classification for lung adenocarcinoma (AD) based on predominant histologic subtypes, such as lepidic, papillary, acinar, solid, and micropapillary; this system reportedly reflects well outcomes of patients with surgically resected lung AD.

In this study, we compared predominant subtypes between primary lung tumors and lymph node metastatic lesions in 24 patients with surgically treated lung adenocarcinoma with lymph node metastases. Additionally, we analyzed prognostic implications of these predominant histologic subtypes. We observed several discordance patterns between predominant subtypes in primary lung tumors and lymph node metastases. Concordance rates were 22%, 64%, and 100%, respectively, in papillary-, acinar-, and solid-predominant primary lung tumors. We observed that the predominant subtype in the primary lung tumor (HR 12.7, P = 0.037), but not that in lymph node metastases (HR 0.18, P = 0.13), determines outcomes in patients with surgically resected lung AD with lymph node metastases.

    The authors aimed to evaluate the efficacy of application of ultrasound dissection technology and coagulation by using "Harmonic Focus" (HF) instrument, while performing anatomical resection of the lung in open thoracic surgery. The method was carried out in serial 20 patients with lung cancer, whom the lung anatomical resection was performed. A long attachment (17 cm) with curved branches was applied. There were 11 lobectomies and 9 pneumoectomies. The application of HF allowed the dissection of pleural adhesions, pulmonary ligament, a separation of roots of the lung elements, lymphatic nodes of roots of the lung and mediastinum, in spite of being very close to vessels. A fatty tissue of the mediastinum was removed quickly and practically without blood. The HF considerably accelerated the process of vessel treatment, especially, while performing the lobectomy. At the same time, the attempts of application of HF instrument for separation of interlobal fissure resulted in not quite satisfactory aerostasis and hemostasis. The duration of the lobectomy was 127 +/- 35 minutes at the average and in the case of pneumoectomy, it consisted of 120 +/- 45 minutes. An intraoperative hemorrhage was 300 +/- 145 ml. A quantity of exudates was 440 +/- 280 ml by drainage on the first day. The pleural cavity drainage was used during 3 +/- 1 days. The HF instrument, which was applied for ultrasonic dissection and coagulation, was characterized by multifunctionality and simplicity of usage. It was recommended for a wide application in the thoracic surgery for performing the anatomical lung resections by thoracotomy method. PMID:25055517

    Pulmonary nodule could be identified by intraoperative fluorescence imaging system from systemic injection of indocyanine green (ICG) which achieves enhanced permeability and retention (EPR) effects. This study was performed to evaluate optimal injection time of ICG for detecting cancer during surgery in rabbit lung cancer model. VX2 carcinoma cell was injected in rabbit lung under fluoroscopic computed tomography-guidance. Solitary lung cancer was confirmed on positron emitting tomography with CT (PET/CT) 2 weeks after inoculation. ICG was administered intravenously and fluorescent intensity of lung tumor was measured using the custom-built intraoperative color and fluorescence merged imaging system (ICFIS) for 15 hours. Solitary lung cancer was resected through thoracoscopic version of ICFIS. ICG was observed in all animals. Because Lung has fast blood pulmonary circulation, Fluorescent signal showed maximum intensity earlier than previous studies in other organs. Fluorescent intensity showed maximum intensity within 6-9 hours in rabbit lung cancer. Overall, Fluorescent intensity decreased with increasing time, however, all tumors were detectable using fluorescent images until 12 hours. In conclusion, while there had been studies in other organs showed that optimal injection time was at least 24 hours before operation, this study showed shorter optimal injection time at lung cancer. Since fluorescent signal showed the maximum intensity within 6-9 hours, cancer resection could be performed during this time. This data informed us that optimal injection time of ICG should be evaluated in each different solid organ tumor for fluorescent image guided surgery.

    Using a double-blind cross-over design, a single dose of 100 mg almitrine bismesylate and placebo were administered orally to eight patients with chronic airflow obstruction having undergone bilateral carotid body resection (BCBR) up to two years earlier to alleviate their extreme dyspnoea. In an open study, two other patients have been given almitrine before and three weeks after BCBR. In all patients, arterial blood gases, ventilation and breathing patterns, neuromuscular drive and hypoxic responsiveness have been studied before and three hours after drug administration. Almitrine failed to improve gas exchange in the patients with BCBR, nor did it affect ventilation, ventilatory or hypoxic drive. In the patients studied before and after BCBR, almitrine only improved gas exchange significantly before BCBR. It is concluded that in man almitrine acts solely as a peripheral chemoreceptor agonist and that the well-documented improvement in V/Q relationship is mediated through carotid body stimulation.

High resolution computed tomography showed bilateral pneumothorax and numerous round and oval, thin-walled lung cysts. Microscopically, each small cyst was composed of distended subpleural alveolar spaces. Tumor cells, characteristic of acinar adenocarcinoma, obstructed and narrowed the terminal bronchioles. There was no tumor necrosis or mucin production. This suggested check-valve as a possible mechanism of the thin-walled cysts and pneumothorax. Genetic analysis suggested that the tumors were positive for epidermal growth factor receptor mutation L858R in exon 21. Bilateral spontaneous pneumothorax and thin-walled cysts in association with lung cancer is rarely reported and may be confused with cystic benign lung lesions. PMID:27042232

    Full Text Available Abstract Background Myocardial infarction can be difficult to diagnose after lung surgery. As recent diagnostic criteria emphasize serum cardiac markers (in particular serum troponin we set out to evaluate its clinical utility and to establish the long term prognostic impact of detected abnormal postoperative troponin levels after lung resection. Methods We studied a historic cohort of patients with primary lung cancer who underwent intended surgical resection. Patients were grouped according to known postoperative troponin status and survival calculated by Kaplan Meier method and compared using log rank. Parametric survival analysis was used to ascertain independent predictors of mortality. Results From 2001 to 2004, a total of 207 patients underwent lung resection for primary lung cancer of which 14 (7% were identified with elevated serum troponin levels within 30 days of surgery, with 9 (64% having classical features of myocardial infarction. The median time to follow up (interquartile range was 22 (1 to 52 months, and the one and five year survival probabilities (95% CI for patients without and with postoperative troponin elevation were 92% (85 to 96 versus 60% (31 to 80 and 61% (51 to 71 versus 18% (3 to 43 respectively (p T stage and postoperative troponin elevation remained independent predictors of mortality in the final multivariable model. The acceleration factor for death of elevated serum troponin after adjusting for tumour stage was 9.19 (95% CI 3.75 to 22.54. Conclusion Patients with detected serum troponin elevation are at high risk of early mortality with or without symptoms of myocardial infarction after lung resection.

    To determine the effect of lung resection on left ventricular function, 29 surgical patients were examined by using a nuclear stethoscope as a non-invasive means for measuring ventricular function at exercise. Pre- and post-operative parameters were obtained at rest and exercise. At rest, postoperative stroke volume (SV), end-diastolic volume (EDV), ejection fraction (EF), and ejection rate (ER) were significantly decreased; heart rate (HR) was significantly increased; and both filling rate (FR) and cardiac output (CO) remained unchanged. At maximum exercise, postoperative EDV, SV, ER and FR were significantly decreased; and there was no significant difference in either HR or EF, resulting in a significantly decreased CO. A ratio of CO and FR at maximum exercise to at rest was significantly decreased after surgery, as compared with that before surgery. According to the number of lobe resection, similar findings for all parameters, except for EF, were observed in the group of two lobe or more resection (n=13); and only two parameters, ER and FR, had the same tendency as those mentioned above in the group of a single lobe resection (n=16). The age group of 60 years or less (n=14) had similar findings for all parameters. In the group of 65 years or more (n=10), resting HR after surgery was not different from that before surgery; and postoperative CO was significantly decreased at rest, but not different from preoperative value at maximum exercise. In conclusion, left ventricular function associated with lung resection is reflected by decreased EDV and SV resulting from reduced pre-load. These changes may be corrected at rest, but not corrected at maximum exercise, resulting in decreased CO. More noticeable decrease in EDV and SV seems to be associated with larger lung resection. In older patients, HR is not corrected well, resulting in a decrease in CO at rest. (N.K.).

    [Purpose] The purpose of this study was to evaluate the effects of a pulmonary rehabilitation education program for caregivers on patients who underwent lung resection surgery. [Subjects] Subjects who underwent lung resection by visual assisted thoracotomy (VATs) were selected and divided into a control group of 19 and an experimental group of 22. [Methods] The experimental group received a pulmonary rehabilitation education program for caregivers, while the control group received typical care for 4 weeks. This study assessed the subjects 2 weeks (baseline) and 6 weeks after surgery (4 weeks). The forced vital capacity (FVC) and forced expiratory volume in 1 sec (FEV1) were measured to evaluate pulmonary function. A visual analogue scale (VAS) was utilized to evaluate pain. [Results] Pulmonary function (FVC and FEV1) increased more in the experimental group compared with the control group. Furthermore, VAS scores were lower in the experimental group compared with the control group. [Conclusion] A pulmonary rehabilitation education program for caregivers had a positive effect on pulmonary function in patients with lung cancer after lung resection. PMID:25729198

    During one-lung ventilation (OLV) in the lateral position, the dependent, ventilated lung receives more blood flow than the non-dependent, non-ventilated lung owing to gravity, improving the match of ventilation and perfusion. Conversely, in the rare clinical situations when OLV is applied to the non-dependent lung, arterial oxygenation can get worse due to considerable shunt flow to the dependent non-ventilated lung. We report a case of severe hypoxemia during carinal resection under OLV of ...

    An 88-year-old woman, with a history of resection of stage IIA lung cancer in 1998, was referred to our hospital in August 2010 complaining of upper abdominal pain, vomiting, and dark brown stools. After endoscopic examination, she was admitted with a diagnosis of Mallory-Weiss syndrome. Vomiting occurred when food intake was resumed after fasting. Intestinal obstruction was suspected on abdominal radiography, and complete small bowel obstruction was confirmed by contrast-enhanced imaging after placement of an ileus tube. A small intestinal tumor with intussusception was detected by computed tomography. At laparotomy, there was no ascites. Intussusception was found due to an ileal tumor located approximately 50 cm from the ileocecal valve, and we performed partial small bowel resection. The resected small intestine contained a submucosal tumor approximately 40 mm in diameter that had penetrated the bowel wall to reach the serosa. Pathological examination revealed a submucosal tumor that showed poor continuity with the surrounding mucosa, while the histology was squamous cell carcinoma. Immunohistochemistry showed that the tumor was CK7 positive, CK20 negative, TTF-1 negative, and CK10 positive. Based on these findings, we made a diagnosis of small intestinal metastasis at 12 years after radical resection of squamous cell carcinoma of the lung. PMID:26662663

    Background To assess the safety and efficacy of combined surgery for patients with concurrent lung cancer and severe coronary heart disease (CHD). Methods Between 2003 and 2014, 34 patients with stage I or II lung cancer and simultaneous severe CHD underwent combined off-pump coronary artery bypass (OPCAB) grafting and lung resection. Surgically, myocardial revascularization was performed first and followed by lobectomies through the same or a second incision. Video-assisted thoracoscopes were used in some cases. Five patients also received chemotherapy before or after combined surgery in an effort to improve the long-term survival. Results All patients survived the operation and no new myocardial infarctions (MIs) occurred in the perioperative period. The most frequent complications were cardiac arrhythmias (5 cases), atelectasis (4 cases), and pulmonary infections (2 cases). All patients were followed up for 5–60 months. Within this period, 6 patients (17.6%) died due to cancer recurrence. The 3- and 5-year survivals were 75% and 67% for these lung cancer patients, respectively. Conclusions Combined OPCAB and pulmonary resection for early stage lung cancer patients with concurrent severe CHD is a relatively safe and effective treatment with satisfactory long-term survival rates, especially for those patients with three-vessel disease who are not usually candidates for percutaneous coronary intervention (PCI) before open surgery.

    Thirty eight patients with non-small cell lung cancer have been treated with radiation therapy after non-curative resection or exploratory thoracotomy during the past 20 years. Tumors were surgically staged; Three patients were Stage I, 6 Stage II, and 29 Stage III. Twenty four patients had epidermoid carcinoma, 11 adenocarcinoma and 3 large cell carcinoma. Fifteen patients underwent incomplete mediastinal lymph node resections, 19 had macroscopic or microscopic residual tumors and 4 underwent only biopsies. The dose of radiation to microscopic or macroscopic residual tumors was more than 60 Gy. Chemotherapy was not used as part of the initial therapy in any patient. The overall 5-year survival rate was 44%. The actuarial 5-year survivals for the patients with Stage II and those with Stage III were 44% and 39% respectively. 5-year survivals for those with a relatively non-curative resection and those with an absolutely non-curative resection were 48% and 43% respectively. Of the 8 patients who are alive more than 5 years, 4 had epidermoid carcinoma and 4 had adenocarcinoma. Two patients had recurrences within the irradiated area. No radiation injuries were observed. Radiation therapy after non-curative resection appears to be effective for local control and survival. (author).

    Full Text Available Abstract Background Predicting postoperative lung function is important for estimating the risk of complications and long-term disability after pulmonary resection. We investigated the capability of vibration response imaging (VRI as an alternative to lung scintigraphy for prediction of postoperative lung function in patients with intrathoracic malignancies. Methods Eighty-five patients with intrathoracic malignancies, considered candidates for lung resection, were prospectively studied. The projected postoperative (ppo lung function was calculated using: perfusion scintigraphy, ventilation scintigraphy, and VRI. Two sets of assessments made: one for lobectomy and one for pneumonectomy. Clinical concordance was defined as both methods agreeing that either a patient was or was not a surgical candidate based on a ppoFEV1% and ppoDLCO% > 40%. Results Limits of agreement between scintigraphy and VRI for ppo following lobectomy were -16.47% to 15.08% (mean difference = -0.70%;95%CI = -2.51% to 1.12% and for pneumonectomy were -23.79% to 19.04% (mean difference = -2.38%;95%CI = -4.69% to -0.07%. Clinical concordance between VRI and scintigraphy was 73% for pneumonectomy and 98% for lobectomy. For patients who had surgery and postoperative lung function testing (n = 31, ppoFEV1% using scintigraphic methods correlated with measured postoperative values better than projections using VRI, (adjusted R2 = 0.32 scintigraphy; 0.20 VRI, however the difference between methods failed to reach statistical significance. Limits of agreement between measured FEV1% postoperatively and ppoFEV1% based on perfusion scintigraphy were -16.86% to 23.73% (mean difference = 3.44%;95%CI = -0.29% to 7.16%; based on VRI were -19.56% to 28.99% (mean difference = 4.72%;95%CI = 0.27% to 9.17%. Conclusions Further investigation of VRI as an alternative to lung scintigraphy for prediction of postoperative lung function is warranted.

    Several landmark study elucidated that adjuvant cisplatin-based chemotherapy for stage II-IIIA non-small cell lung cancer (NSCLC)patients after appropriate surgical resection can significantly improve 5-year survival rate. Meta-analysis of modern cisplatin based adjuvant chemotherapy trial confirmed this benefit. Furthermore, in Japan, large randomized trial and metaanalysis assessing the efficacy of uracil-tegafur(UFT)for stage I patients with completely resected NSCLC reported that UFT can significantly improve 5-year survival rate. Meta-analysis of subgroup assessed that effectiveness of UFT for stage I NSCLC patients with a tumor lager than 2 cm. According to these evidence, cisplatin-based adjuvant chemotherapy for stage II-III A NSCLC and UFT for stage I NSCLC patients with a tumor lager than 2 cm are used standard postoperative adjuvant chemotherapy in Japan. In recent year, it is presumed that personalized care will be necessary to re-evaluate strategies for postoperative adjuvant chemotherapy of lung cancer. Considering histological subtype of lung cancer, several randomize trial for postoperative adjuvant chemotherapy with non-squamous NSCLC or high neuroendocrine tumor of lung are ongoing. In addition, recent studies of biological research indicate that some tumor marker such as ERCC1 may had a predictive value for selecting patients who will derive the benefit from adjuvant chemotherapy.

  16. Effect of resection on local failure in irradiated non-oat cell carcinoma of the lung

    International Nuclear Information System (INIS)

    From January 1969 through December 1979, 171 patients completed a course of high dose definitive radiotherapy alone for non-oat cell carcinoma of the lung. During the same period, 53 patients completed a course of definitive postoperative radiotherapy after undergoing resection of the primary tumor. The two groups were otherwise very similar with regard to patient related and tumor related variables. A detailed analysis of the incidence of clinically documented local (in-field) failure on the basis of clinical T and N stages was performed. A comparison of the incidence of local failure as the first site of failure for patients with T/sub 1-2/ tumors demonstrated a statistically significant decrease in local failure in patients whose primary tumors were resected. Histology (epidermoid vs. non-epidermoid) had no apparent effect on the frequency of local failure, either with or without resection. A review of past experience indicates that local failure is common after definitive irradiation alone, and is due to a low rate of sterilization of the primary tumor, even with tolerance doses of irradiation. Data are presented to support a reappraisal of the role of combined resection and irradiation in future clinical trials, to reduce the present unacceptably high rate of local failure in potentially curable patients treated by irradiation alone

  17. Stability and Heterogeneity of Expression Profiles in Lung Cancer Specimens Harvested Following Surgical Resection

    Full Text Available One of the major concerns in microarray profiling studies of clinical samples is the effect of tissue sampling and RNA extraction on data. We analyzed gene expression in lung cancer specimens that were serially harvested from tumor mass and snap-frozen at several intervals up to 120 minutes after surgical resection. Global gene expression was profiled on cDNA microarrays, and selected stress and hypoxia-activated genes were evaluated using real-time reverse transcription polymerase chain reaction (RT-PCR. Remarkably, similar gene expression profiles were obtained for the majority of samples regardless of the time that had elapsed between resection and freezing. Real-time RT-PCR studies showed significant heterogeneity in the expression levels of stress and hypoxia-activated genes in samples obtained from different areas of a tumor specimen at one time point after resection. The variations between multiple samplings were significantly greater than those of elapsed time between sampling/freezing. Overall samples snap-frozen within 30 to 60 minutes of surgical resection are acceptable for gene expression studies, thus making sampling and snap-freezing of tumor samples in a routine surgical pathology laboratory setting feasible. However, sampling and pooling from multiple sites of each tumor may be necessary for expression profiling studies to overcome the molecular heterogeneity present in tumor specimens.

    Background and Purpose To report on the outcomes of treating children with a persistent esotropia with an injection of botulinum toxin in a medial rectus muscle. Patients and Methods The medical records of all children at one institution with a persistent esotropia after bilateral medial rectus recessions and bilateral lateral rectus resections who were then treated with a botulinum toxin injection were reviewed. Results Five patients with a mean preoperative esotropia of 37 PD (range, 25-50 PD) underwent bilateral medial rectus recessions and then bilateral lateral rectus resections. Their residual esotropia (mean, 25 PD; range, 18-35) was then treated with a single injection of 3- 5 units of botulinum toxin into one medial rectus muscle. The patients were then followed for a mean of 34 months (range, 14 to 79 months). At last follow-up, 2 patients had an esotropia <10 PD. The other 3 patients had no long-term improvement in their ocular alignment. Two of these patients then underwent additional strabismus surgery. In both cases, they then developed a consecutive exotropia. Conclusion Treatment with a single injection of botulinum toxin was beneficial in 2 of 5 children. Botulinum toxin treatment alone did not result in a consecutive exotropia in any patients treated. PMID:24260804

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether a fine-needle aspiration (FNA) diagnosis is of sufficient reliability for the diagnosis of lung cancer prior to a major lung resection. Altogether, 112 papers were found using the reported search, of which 13 papers presented the best evidence to answer the clinical question. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. The tabulated studies include two meta-analyses, one systematic review, one randomized controlled trial (RCT) and nine cohort studies. The specificity reported for FNA in the diagnosis and staging of lung cancer ranged from 96.2 to 100%. One meta-analysis reported a specificity of 97%. Another meta-analysis reported a specificity of 98.8%. A systematic review reported a specificity of 97%. An RCT reported a specificity of 96.2-100%. We conclude that the FNA for lung cancer is reported to be highly specific prior to major lung resection with a very low false positive rate. However, although a false positive may occasionally be acceptable in lobectomies, where the lobes are often removed without histology, all steps should be taken to avoid a false positive result in pneumonectomy considering the serious consequences of embarking upon such an operation in the small number of patients with a false positive result, and we recommend that a positive FNA result should be confirmed by means of alternative sampling methods. We also acknowledge that obtaining an additional biopsy specimen would add to the risk of morbidity and costs; therefore, any benefits should be weighed against risks and additional costs.

    Thanks to the experience gained through the improvement of video-assisted thoracoscopic surgery (VATS) technique, and the enhancement of surgical instruments and high-definition cameras, most pulmonary resections can now be performed by minimally invasive surgery. The future of the thoracic surgery should be associated with a combination of surgical and anaesthetic evolution and improvements to reduce the trauma to the patient. Traditionally, intubated general anaesthesia with one-lung ventilation was considered necessary for thoracoscopic major pulmonary resections. However, thanks to the advances in minimally invasive techniques, the non-intubated thoracoscopic approach has been adapted even for use with major lung resections. An adequate analgesia obtained from regional anaesthesia techniques allows VATS to be performed in sedated patients and the potential adverse effects related to general anaesthesia and selective ventilation can be avoided. The non-intubated procedures try to minimize the adverse effects of tracheal intubation and general anaesthesia, such as intubation-related airway trauma, ventilation-induced lung injury, residual neuromuscular blockade, and postoperative nausea and vomiting. Anaesthesiologists should be acquainted with the procedure to be performed. Furthermore, patients may also benefit from the efficient contraction of the dependent hemidiaphragm and preserved hypoxic pulmonary vasoconstriction during surgically induced pneumothorax in spontaneous ventilation. However, the surgical team must be aware of the potential problems and have the judgement to convert regional anaesthesia to intubated general anaesthesia in enforced circumstances. The non-intubated anaesthesia combined with the uniportal approach represents another step forward in the minimally invasive strategies of treatment, and can be reliably offered in the near future to an increasing number of patients. Therefore, educating and training programmes in VATS with non

    Full Text Available Abstract Background Pulmonary air leaks are common complications of lung resection and result in prolonged hospital stays and increased costs. The purpose of this study was to investigate whether, compared with standard care, the use of a synthetic polyethylene glycol matrix (CoSeal® could reduce air leaks detected by means of a digital chest drain system (DigiVent™, in patients undergoing lung resection (sutures and/or staples alone. Methods Patients who intraoperatively showed moderate or severe air leaks (evaluated by water submersion tests were intraoperatively randomized to receive just sutures/staples (control group or sutures/staples plus CoSeal® (sealant group. Differences among the groups in terms of air leaks, prolonged air leaks, time to chest tube removal, length of hospital stay and related costs were assessed. Results In total, 216 lung resection patients completed the study. Nineteen patients (18.1% in the control group and 12 (10.8% patients in the sealant group experienced postoperative air leaks, while a prolonged air leak was recorded in 11.4% (n = 12 of patients in the control group and 2.7% (n = 3 of patients in the sealant group. The difference in the incidence of air leaks and prolonged air leaks between the two groups was statistically significant (p = 0.0002 and p = 0.0013. The mean length of hospital stay was significantly shorter in the sealant group (4 days than the control group (8 days (p = 0.0001. We also observed lower costs in the sealant group than the control group. Conclusion The use of CoSeal® may decrease the occurrence and severity of postoperative air leaks after lung resection and is associated with shorter hospital stay. Trial registration Not registered.

    A colopleural fistula is a rare condition reported to be caused by Crohn's disease, a malignant tumor of the gastrointestinal tract, and other clinical conditions. Some studies have noted that a sub-diaphragmatic abscess, usually organized following abdominal surgery, may play some role in the formation of this type of fistula. Therefore, a colopleural fistula is a complication very rarely encountered by thoracic surgeons after lung resection.We experienced an extremely rare case of colopleural fistula following a left lower lobectomy for lung aspergillosis. Here, we report a 71-year-old man with a surgical history of proximal gastrectomy for gastric cancer. He underwent left lower lobectomy of the lung for aspergillosis, and a colopleural fistula occurred on the second operative day as a complication. Aspergillus might be responsible for forming a fistula between the colon and lung via the diaphragm, and lung surgery manifested this rare condition. Although some reports suggest that surgical treatment is mandatory to cure this fistula, an immediate colostomy in our case reduced the internal pressure of the colon, thus enabling spontaneous closure of the fistula with appropriate drainage and antibiotics. The patient was discharged in a good condition. PMID:27108124

    Full Text Available Background and objective The treatment for early-stage non-small cell lung cancer is primarily surgical. However, the optimal extent of mediastinal lymph node resection remains to be determined. The aim of the current study is to investigate the effect of a pulmonary wedge resection on aged patients with lung cancer. Methods A total of 15 lung cancer patients aged over 70 years were treated via video-assisted thoracoscopic surgery (VATS wedge resection and mediastinal lymph node sampling from June 2004 to February 2008. Mediastinal lymph node sampling included stations 2R, 4R, 8 and 9 for the right-sided cancers and stations 5, 6, 8 and 9 for the left-sided cancers. Results VATS wedge resection and mediastinal lymph node sampling for aged patients with peripheral lung cancer are minimally invasive treatments with a short operative time and low postoperative morbidity. The 1-year and 3-year survival rates were 100% and 86.6%, respectively. Conclusion VATS wedge resection and mediastinal lymph node sampling can be an alternative treatment for aged patients with early peripheral lung cancer.

    Acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) in lung cancer patients is a critical factor in post-operative mortality. The cause of AE development is unknown and AE may occur in patients without the diagnosis of IPF. We have conducted a retrospective study of consecutive patients who underwent lung cancer surgery since January 2004. Sixty-two patients with fibrous findings in preoperative high-resolution computed tomography were enrolled in the present study and clinicopatho...

    Full Text Available The metastasis of the lungs develop in proportion as 30% of all cancers. Spontaneous pneumothorax is a rarely found but clinically significant complication in lung and trachea tumors. Spontaneous pneumothorax may also occur in metastatic tumors. Different levels of dispnea are observed in metastatic lung tumors according to the prevalance of the lesions. Sudden or progressive incline in the shortness of breath in these patients may be the harbinger of a spontaneous pneumothorax. In this presentation, underwent left nephrectomy with a diagnosis of renal cell carcinoma, bilateral pulmonary metastases after nephrectomy for two years due to the development of spontaneous pneumothorax in consecutive patients given chemotherapy was discussed with the development of literature.

  7. Takotsubo cardiomyopathy associated with pulmonary resections after induction chemoradiotherapy for non-small cell lung cancer

    International Nuclear Information System (INIS)

    Takotsubo cardiomyopathy (TTC), also known as transient left ventricular (LV) apical ballooning syndrome, is characterized by transient LV dysfunction. We present the case of a 72-year-old man who was diagnosed as having TTC after surgery for two lung tumors. The patient was treated with induction chemoradiotherapy (CRT) followed by pulmonary resections for double primary non-small cell lung cancers (NSCLC): cT4N1M0 disease in the right lung and cT2N0M0 in the left lung. Induction CRT was performed. A right upper lobectomy was initially performed, and a left upper divisionectomy was subsequently performed. At 3 days after the second surgery, he developed dyspnea and general fatigue accompanied by a T-wave inversion on electrocardiography (ECG). An echocardiogram revealed akinesis at the apex with a 30% ejection fraction. He was diagnosed as having TTC and recovered with supportive care. This case is the first report of TTC occurring after tri-modality therapy for NSCLC. (author)

  8. Prediction of lung cancer spread and functional resectability by 133Xe radiospirometry

    International Nuclear Information System (INIS)

    Sixty-six patients with primary lung cancer who underwent thoracotomy were studied to determine the correlations among 133Xe radiospirometry, surgical procedures and histological extension of the lung cancer. Disturbance in the regional perfusion (Q radical per cent) was more prominent than disturbance of the regional ventilation (V radical per cent), as the pathological stage and t factor proceeded, while V radical per cent and Q radical per cent were disturbed almost equally in relation to the pathological n factor. Lobectomy was impossible in patients with a Q radical per cent of less than 33 per cent of the total, but low perfusion did not necessarily contraindicate surgery. The predicted postoperative FEVsub(1.0) was calculated according to the equation of (1 - b/a x (V radical per cent or Q radical per cent)) x (preoperative FEVsub(1.0)), where a and b were the number of subsegments in the lung lobes on the involved side and the resected lobe. The predicted and actually measured postoperative FEVsub(1.0) showed significant correlations (<0.001) in both equations. We conclude that Q radical per cent reflects a complex pattern of lung cancer spread more sensitivity than dose V radical per cent, and the significance of V radical per cent and Q radical per cent in terms of prediction of postoperative EFVsub(1.0) seems to be equivocal.

    To assess the diagnostic performance of PET/MR in patients with non-small-cell lung cancer. Fifty consecutive consenting patients who underwent routine {sup 18}F-FDG PET/CT for potentially radically treatable lung cancer following a staging CT scan were recruited for PET/MR imaging on the same day. Two experienced readers, unaware of the results with the other modalities, interpreted the PET/MR images independently. Discordances were resolved in consensus. PET/MR TNM staging was compared to surgical staging from thoracotomy as the reference standard in 33 patients. In the remaining 17 nonsurgical patients, TNM was determined based on histology from biopsy, imaging results (CT and PET/CT) and follow-up. ROC curve analysis was used to assess accuracy, sensitivity and specificity of the PET/MR in assessing the surgical resectability of primary tumour. The kappa statistic was used to assess interobserver agreement in the PET/MR TNM staging. Two different readers, without knowledge of the PET/MR findings, subsequently separately reviewed the PET/CT images for TNM staging. The generalized kappa statistic was used to determine intermodality agreement between PET/CT and PET/MR for TNM staging. ROC curve analysis showed that PET/MR had a specificity of 92.3 % and a sensitivity of 97.3 % in the determination of resectability with an AUC of 0.95. Interobserver agreement in PET/MR reading ranged from substantial to perfect between the two readers (Cohen's kappa 0.646 - 1) for T stage, N stage and M stage. Intermodality agreement between PET/CT and PET/MR ranged from substantial to almost perfect for T stage, N stage and M stage (Cohen's kappa 0.627 - 0.823). In lung cancer patients PET/MR appears to be a robust technique for preoperative staging. (orig.)

  12. Efficacy of lung ventilation scintigram and exercise pulmonary hemodynamic measurement to evaluate operability for pulmonary resection

    International Nuclear Information System (INIS)

    Preoperative evaluation of patients with lung cancer should include data concerning both resectability and operability. Operability addresses the question how much pulmonary tissue can be safely removed. The purpose of this study is to demonstrate an efficacy of the lung ventilation scintigram and measurement of exercise change in pulmonary hemodynamic parameters by detecting respiratory and circulatory reserve of pulmonary function. Predicted postoperative forced vital capacity (FVC) were calculated from the data of lung scintigram and preoperative spirometry by means of subsegmental formula. Accuracy of prediction was confirmed by spirometry 6 months after the operation. Correlation coefficient between predicted value and actually measured one was R=0.95, and simple regression formula was y=0.98x-10.4. It was recommended that the lower limit should be setted at 40% by the calculated postoperative %FVC. Exercise test were performed by means of bicycle ergometer with the measurement of pulmonary arterial pressure and cardiac output. Pulmonary arterial resistance index (PARI) were also calculated. In younger group rise of pulmonary arterial pressure during exercise was gentle, and PARI was settled between 150 to 200 in high output state. But in older group rise of pulmonary aerial pressure was steep and PARI was over 200 in some cases, just like the case of COLD. It should be recommended to set the upper limit of PARI at 400 in maximum exercise. (author)

    Full Text Available Lymphangioleiomyomatosis (LAM is a rare disease that leads to airways and lymphatic channels obstruction due to abnormal smooth muscle proliferation. It presents with dyspnea, pneumothorax or chylothorax. Lung transplantation (LT has emerged as a valuable therapeutic option with limited reports. We report a case of LAM that underwent double LT and complicated by refractory bilateral chylothorax which was managed successfully by povidone-iodine pleurodesis and the addition of sirolimus to the post-transplantation immunosuppressive therapy. The patient has no recurrence with 24 months follow-up.

  16. Pulmonary resection after chemoradiotherapy for advanced non-small cell lung cancer. The impact of presurgical radiation therapy

    International Nuclear Information System (INIS)

    Chemoradiation therapy (CRT) is recommended as standard care for stage III non-small cell lung cancer (NSCLC), but some patients experience local recurrence after the treatment. Surgical resection after CRT involves high surgical risk, but is expected to increase the curability. This study was performed to investigate the impact of presurgical CRT on the postoperative outcome, focusing especially on the effect of radiation therapy. Twenty-six patients with stage III (N2 or T3-4) NSCLC underwent pulmonary resection after CRT. A radiation dose up to 40-70 Gy was given with concurrent chemotherapy. The morbidity, mortality and survival after surgical resection were examined. Lung resection was performed as lobectomy (73%) or pneumonectomy (19%). Postoperative complications occurred in 12 patients (morbidity 46.1%). The overall 5-year survival of the entire cohort was 69.7%. The factors associated with favorable long-term survival included a pathological complete response (CR) and mediastinal node negative condition after CRT, and microscopic complete resection. Surgical resection for stage III patients after CRT may provide a survival benefit with acceptable morbidity. The surgical morbidity may be increased by prior radiation therapy, thus, surgeons should be familiar with the available countermeasures to reduce the surgical risk. (author)

  17. Predominant histologic subtype in lung adenocarcinoma predicts benefit from adjuvant chemotherapy in completely resected patients: discovery of a holy grail?

    2016-01-01

    The recently published 2015 World Health Organisation (WHO) classification of lung tumors, which is based on the 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ATS) multidisciplinary classification, recommends diagnosis of resected lung adenocarcinoma according to the predominant histologic subtype. This has been shown to correlate with overall and disease-free survival (DFS) in many studies from four continents. Now classification according to predominant histologic subtype has been demonstrated to predict benefit from adjuvant chemotherapy in a subset of patients with completely resected lung adenocarcinoma previously included in the International Adjuvant Lung Cancer Trial (IALT), JBR.10, Cancer and Leukemia Group B (CALGB) 9633 and Adjuvant Navelbine International Trialist Association 01 (ANITA) adjuvant chemotherapy trials, all of which were part of the LACE-Bio study. This "hot-off-the press" landmark investigation further cements the clinical importance of classification of resected lung adenocarcinoma according to predominant histologic subtype and suggests that it could be a critical factor for patient stratification in future clinical trials.

    Full Text Available Abstract Background CD44s is a cell adhesion molecule known to mediate cellular adhesion to the extracellular matrix, a prerequisite for tumor cell migration. CD44s plays an important role in invasion and metastasis of various cancers. In the present study, we sought to determine whether CD44s is involved in clinical outcomes of patients with resected non-small cell lung cancer (NSCLC. Methods Using immunohistochemical staining, we investigated CD44s protein expression using tissue array specimens from 159 patients with resected NSCLC (adenocarcinoma (AC; n = 82 and squamous cell carcinoma (SCC; n = 77. Additionally, the immunoreactivity of cyclooxygenase (COX-2 was also studied. The clinicopathological implications of these molecules were analyzed statistically. Results High CD44s expression was detected more frequently in NSCLC patients with SCC (66/72; 91.7% than in those with AC histology (P 0.001. Additionally, high CD44s expression was significant correlated with more advanced regional lymph node metastasis (P = 0.021. In multivariate analysis of survival in NSCLC patients with AC histology, significant predictors were lymph node metastasis status (P P = 0.046, and high CD44s expression (P = 0.014. For NSCLC patients with SCC histology, the significant predictor was a more advanced tumor stage (P = 0.015. No significant association was found between CD44s and clinical outcome (P = 0.311. Conclusions High CD44s expression was a negative prognostic marker with significance in patients with resected NSCLC, particularly those with AC histology, and was independent of tumor stage.

    Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the "Plan Cancer") according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005-2007, 2008-2010 and 2011-2013.Global crude IHM was 3.9%: 4.3% during 2005-2007, 4% during 2008-2010 and 3.5% during 2011-2013 (p43 resections per year (adjusted (a)OR 1.48, 95% CI 1.197-1.834). The risk of death was lower in the period 2011-2013 than in the period 2008-2010 (aOR 0.841, 95% CI 0.764-0.926). Adjustment variables (age, sex, Charlson score and type of resection) were significantly linked to IHM, whereas the type of hospital was not.The French national strategy for quality improvement seems to have induced a significant decrease in IHM.

    Full Text Available Abstract Background adenosquamous carcinoma (ADSQ of non-small cell lung cancer (NSCLC is a rare disease and the biological behavior and clinicopathological characteristics have not yet been thoroughly described. Method This study reviewed the patient charts of 11 (1.6% ADSQ cases among 779 patients with primary lung cancer who underwent a lung resection. The characteristics and clinicopathological factors were evaluated retrospectively. Results Six of the 11 patients with ADSQ were male and five were female. The mean age was 67.3 years' olds. Three patients had pathological stage IA, one patient each had stage IB and IIA, five patients had stage IIIA, and one patient stage IIIB. Five patients had coexistent double cancer including 2 gastric, 1 rectal, 1 prostate and 1 bladder cancer. ADSQ was found less frequently in males than squamous cell carcinoma (SQ. ADSQ was found more frequently in older patients, with advanced stage, advanced T status, and lymph node metastases than adenocarcinoma (AD. The proportion with coexistent double cancer of AD, SQ, and ADSQ were 21.1, 17.6, and 45.5%, respectively. ADSQ had a significantly correlation with double cancer (ADSQ vs. non- ADSQ p = 0.03. A multivariate analysis showed no significant prognostic difference between the patients with ADSQ and non- ADSQ. Conclusions In this study, cases with ADSQ showed no significantly prognostic difference in comparison to AD and SQ. However, surgeons must be cautious of any coexistent double cancer because approximately half of all patients with ADSQ of the lung have double cancer.

    When suitable, surgery still remains the therapeu-tic option to be preferred for patients carrier of colorectal liver and lung metastases. Since thoracophrenolaparotomy should be helpful during liver resection for some of these patients, si-multaneous removal of right lung metastases can be proposed through this approach. Eleven consecutive patients (median age of 53 years) carrier of colorectal liver and lung metastases, underwent single session surgical resection of both liver and right lung lesions by means of J-shaped thoracophrenolapa-rotomy. The median number of liver metastases removed was 5 (range 2-30) and of lung metastases removed was 2 (range 1-3). Lung metastases were located in the upper lobe in 1 pa-tient, in the middle lobe in 2, in the lower lobe in 6, and in the upper and lower lobe in 2. Mortality and major morbidity were nil. Two patients had a minor morbidity: one had wound infection and bile leakage treated conservatively and the other had transient fever. Mean overall survival was 24.4 months. An aggressive surgical approach should be undertaken for colorectal metastases: in case of multifocal liver disease with complex presentations, J-shaped thoracophrenolaparotomy could be considered as safe approach for combined liver and right lung metastasectomies.

    Full Text Available Background: Surgical treatment of non-small cell lung cancer (NSCLC with aortic invasion is still debated.Methods: Thirteen patients with locally advanced (T4 NSCLC and invasion of the descending aorta underwent pneumonectomy (n=9 or lobectomy (n=4 together with aorta en bloc resection and reconstruction (n=8 or subadventitial dissection (n=5, complete lymph node dissection, and had microscopic unsuspected node metastasis at N1 (n=5 and N2/3 (n=8 levels of whom 12 received radiation therapy. Clamp-and-sew was used to resect and reconstruct the aorta.Results: Operative mortality and morbidity rate was 0% and 23%, respectively. Four patients died of systemic tumor relapse and 2 of local recurrence. Six patients were alive after a median follow-up of 40 months (range 15–125 months. Overall 5-year survival rate was 45%. Median survival time and 5-year survival rate of patients after aortic resection was 35 months and 67%, respectively, and was 17 months and 0%, respectively, after aortic subadventi-tial dissection (p=0.001. N1 and N2 nodal status adversely affected survival, but survival difference was not significant (N1 versus N2/3; 52% versus 39% at 5 years; p=0.998.Conclusions: Aortic resection with single station node positive T4 lung cancer can achieve long-term survival. The data indicate that aortic resection-reconstruction is associated with better outcome than subadventitial dissection.

    Background Radical lung resection is the best chance for cure in patients with anatomically resectable non-small cell lung cancer.A retrospective study was performed in an attempt to investigate general rules of major lung resection for non-small cell lung cancer in patients with compromised pulmonary function.Methods Between June 2002 and December 2008,major lung resection was performed in 127 non-small cell lung cancer patients at our institution,who met the criteria of compromised pulmonary function defined as preoperative forced vital capacity <50% of prediction or preoperative forced expiratory volume in one second <50% of prediction.Clinical data of the patients were retrospectively reviewed.Results The patients consisted of 108 males (85.0%) and 19 females (15.0%) with a mean age of 61.7 years.The morbidity rate was 44.1% (56/127) and the mortality rate was 4.7% (6/127).Multivariate analysis identified PaCO2 (P=0.023,OR=2.959,95% C/ 1.164-7.522),the percent predicted postoperative diffusing capacity of the lung for carbon monoxide (P=0.001,OR=0.176,95% C/ 0.064-0.480) and comprehensive preoperative preparation (P=0.048,OR=0.417,95% C/ 0.176-0.993) as the independent predictors of postoperative cardiopuimonary complications that were found in 45 cases.Overall 1-,3- and 5-year survival rates were 90%,55% and 37% respectively.For overall survival,multivariate analysis revealed that TNM staging (P=0.004,OR=1.585,95% C/ 1.154-2.178) was the only independent prognostic factor.Conclusions On the premise of integrated preoperative evaluation and comprehensive preoperative preparation,major lung resection provides an optimal therapeutic for selected non-small cell lung cancer patients with compromised pulmonary function.Hypercapnea and the percent predicted postoperative diffusing capacity of the lung for carbon monoxide <40% could be considered as the independent predictive factors for operative risk in those patients.Chin Med J

  6. Clinicopathologic analysis of resected primary lung cancer with idiopathic pulmonary fibrosis

    International Nuclear Information System (INIS)

    The aim of the present study was to define the clinicopathological features and operative prognosis of patients with primary lung cancer with idiopathic pulmonary fibrosis (IPF). Of the patients who underwent surgery for non-small cell lung cancer from January 2006 to January 2008 in our hospital, 94 patients who had been preoperatively evaluated with high resolution computed tomography (HRCT) were enrolled in this study. We retrospectively analyzed 9 patients (9.6%) who were given a diagnosis of IPF based on HRCT findings. The patients with IPF consisted of 8 men and 1 woman with an average age of 74.7 years. All 9 patients had a smoking history. Patients with IPF had tumors located adjacent to the pleura significantly more frequently than in 85 patients without IPF (77.8% vs 36.5%; P=0.02). Pathologically, squamous cell carcinoma, and moderately or poorly differentiated tumors were detected significantly more frequently in patients with IPF than without IPF (55.6% vs 20.0%; P=0.05, 88.9% vs 42.4%; P=0.01). The standardized uptake value (SUV) of F-18 fluorodeoxyglucose (FDG) on positron emission tomography (PET) of patients with IPF showed a high average value of 11.1 (range, 3.4-31.6). The Ki-67 labeling index also showed a high average value of 46.1%. Up-staging migration from the clinical stage to the pathological stage was noticed in 4 cases due to underestimation of the tumor diameter in 3 cases and intrapulmonary metastasis in 1 case. Recurrences were observed in 4 of 9 cases. Local recurrence was observed in 2 cases (hilar lymph nodes and mediastinal lymph nodes), and distant recurrence was in 2 cases. As primary lung cancer with IPF seems to have a high potential for malignancy and the preoperative T factor can be often underestimated, we should be cautious selecting limited resection as a curative procedure.

    Full Text Available OBJECTIVE: To evaluate whether external suction is more advantageous than water seal in patients undergoing selective pulmonary resection (SPR for lung neoplasm. SUMMARY OF BACKGROUND DATA: Whether external suction should be routinely applied in postoperative chest drainage is still unclear, particularly for lung neoplasm patients. To most surgeons, the decision is based on their clinical experience. METHODS: Randomized control trials were selected. The participants were patients undergoing SPR with lung neoplasm. Lung volume reduction surgery and pneumothorax were excluded. Suction versus non-suction for the intervention. The primary outcome was the incidence of persistent air leak (PAL. The definition of PAL was air leak for more than 3-7 days. The secondary outcomes included air leak duration, time of drainage, postoperative hospital stay and the incidence of postoperative pneumothorax. Studies were identified from literature collections through screening. Bias was analyzed and meta-analysis was used. RESULTS: From the 1824 potentially relevant trials, 6 randomized control trials involving 676 patients were included. There was no difference between external suction and water seal in decreasing the incidence of PAL [95% confidence interval (CI 0.81-2.16; z = 1.10; P = 0.27]. Regarding secondary outcomes, there were no differences in time of drainage (95% CI-0.36-1.56, P = 0.22, postoperative hospital stay (95% CI -.31-.54, P = 0.87 or incidence of postoperative pneumothorax (95% CI 0.18-.02, P = 0.05 between external suction and water seal. CONCLUSIONS: For participants, no differences are identified in terms of PAL incidence, drainage time, length of postoperative hospital stay or incidence of postoperative pneumothorax between external suction and water seal. The bias analysis should be emphasized. To the limitations of the bias and methodological differences among the included studies, we have no recommendation on

    Full Text Available Purpose: The purpose of this study is to evaluate the dosimetric effect of rotational setup errors on the synchronous bi-lateral lung cancer plans generated by the intensity modulated proton therapy (IMPT technique.Methods: The original IMPT plans were generated in for the left planning target volume (PTV and right PTV of the left lung and right lung, respectively. Each plan was generated using two beams (lateral and posterior-anterior with an isocenter placed at the center of the corresponding PTV. The IMPT plans were optimized for a total dose of 74 Gy[RBE] prescribed to each PTV with 2 Gy(RBE per fraction. Original plans were recalculated by introducing simulated rotational errors. For each PTV, 18 rotational plans (±1⁰, ±2⁰, and ±3⁰ for each of the yaw, roll, and pitch rotations were generated. Results: Rotational errors caused the reduction in the clinical target volume (CTV and PTV coverage in new rotational IMPT plans when compared to the original IMPT lung plans. The CTV D99 was reduced by up to 13.3%, 9.1%, and 5.9% for the yaw (+3⁰, roll (-3⁰, and pitch (+3⁰, respectively. The PTV D95 was reduced by up to 8.7%, 7.3%, and 4.6% for the yaw (+3⁰, roll (-3⁰, and pitch (+3⁰, respectively. The PTV V100 showed the highest deviation with a reduction of dose coverage by up to 40.1%, 31.8%, and 33.9% for the yaw (-3⁰, roll (-3⁰, and pitch (+3⁰ respectively. Conclusion: The rotational setup errors with magnitude of ≥2⁰ can produce a significant loss of dose coverage to the target volume in the IMPT of a synchronous bi-lateral lung cancer. The yaw had the most severe impact on the dosimetric results when compared to other two rotational errors (roll and pitch.

  9. Local Failure in Resected N1 Lung Cancer: Implications for Adjuvant Therapy

    International Nuclear Information System (INIS)

    Purpose: To evaluate actuarial rates of local failure in patients with pathologic N1 non–small-cell lung cancer and to identify clinical and pathologic factors associated with an increased risk of local failure after resection. Methods and Materials: All patients who underwent surgery for non–small-cell lung cancer with pathologically confirmed N1 disease at Duke University Medical Center from 1995–2008 were identified. Patients receiving any preoperative therapy or postoperative radiotherapy or with positive surgical margins were excluded. Local failure was defined as disease recurrence within the ipsilateral hilum, mediastinum, or bronchial stump/staple line. Actuarial rates of local failure were calculated with the Kaplan-Meier method. A Cox multivariate analysis was used to identify factors independently associated with a higher risk of local recurrence. Results: Among 1,559 patients who underwent surgery during the time interval, 198 met the inclusion criteria. Of these patients, 50 (25%) received adjuvant chemotherapy. Actuarial (5-year) rates of local failure, distant failure, and overall survival were 40%, 55%, and 33%, respectively. On multivariate analysis, factors associated with an increased risk of local failure included a video-assisted thoracoscopic surgery approach (hazard ratio [HR], 2.5; p = 0.01), visceral pleural invasion (HR, 2.1; p = 0.04), and increasing number of positive N1 lymph nodes (HR, 1.3 per involved lymph node; p = 0.02). Chemotherapy was associated with a trend toward decreased risk of local failure that was not statistically significant (HR, 0.61; p = 0.2). Conclusions: Actuarial rates of local failure in pN1 disease are high. Further investigation of conformal postoperative radiotherapy may be warranted.

    A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether preoperative physiotherapy/pulmonary rehabilitation is beneficial for patients undergoing lung resection. Ten papers were identified using the reported search, of which five represented the best evidence to answer the clinical question. In 2007 a report showed in 13 subjects receiving a preoperative rehabilitation programme (PRP) an improvement of maximum oxygen uptake consumption (VO(2) max) of an average 2.4 ml/kg/min (95% confidence interval 1-3.8; P=0.002). A report in 2008 showed in 12 patients with chronic obstructive pulmonary disease (COPD) and VO(2) max COPD. It was shown in 2006 that by using a cross-sectional design with historical controls that one day of chest physiotherapy comprising inspiratory and peripheral muscle training compared with routine nursing care was associated with a lower atelectasis rate (2% vs. 7.7%) and a median length of stay that was 5.73 days vs. 8.33 days (Pexercise capacity and preserves pulmonary function following surgery. Whether these benefits translate into a reduction in postoperative pulmonary complication is uncertain. PMID:21586476

  11. Nodal involvement pattern in resectable lung cancer according to tumor location

    International Nuclear Information System (INIS)

    The aim in this study was to define the pattern of lymph node metastasis according to the primary tumor location. In this retrospective cohort study, each of the operable patients diagnosed with lung cancer was grouped by tumor mass location. The International Association for the Study of Lung Cancer nodal chart with stations and zones, established in 2009, was used to define lymph node levels. From 2006 to 2010, 197 patients underwent a lobectomy with systematic nodal resection for primary lung cancer at Chiang Mai University Hospital. There were 123 male and 74 female patients, with ages ranging from 16– 85 years old and an average age of 61.31. Analyses of tumor location, histology type, and nodal metastasis were performed. The locations were the right upper lobe in 63 patients (31.98%), the right middle lobe in 18 patients (9.14%), the right lower lobe in 30 patients (15.23%), the left upper lobe in 55 patients (27.92%), the left lower lobe in 16 patients (8.12%), and mixed lobes (more than one lobe) in 15 patients (7.61%). The mean tumor size was 4.45 cm in diameter (range 1.2–16.5 cm). Adenocarcinoma was the most common histological type, which occurred in 132 cases (67.01%), followed by squamous cell carcinoma in 41 cases (20.81%), bronchiolo alveolar cell carcinoma in nine cases (4.57%), and large cell carcinoma in seven cases (3.55%). Eighteen cases (9.6%) had skip metastasis (mediastinal lymph node metastasis without hilar node metastasis). Adenocarcinoma and intratumoral lymphatic invasion were the predictors of mediastinal lymph node metastases. There were statistically significant differences between a tumor in the right upper lobe and the right lower lobe. However, there were no statistically significant differences between tumors in the other lobes. In conclusion, tumor location is not a precise predictor of the pattern of nodal metastasis. Systematic lymph node dissection is the only way to accurately determine lymph node status. Further studies

    Purpose Brain metastasis is the most common complication of brain cancer; nevertheless, primary lung cancer accounts for approximately 20%–40% of brain metastases cases. Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC) in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases ...

In the present study, we examined the correlation of serum and lung inflammatory marker levels following bilateral femur fracture.Materials and methods: 45 Sprague Dawley rats underwent sham operation or bilateral femoral intramedullary pinning and mid-diaphyseal closed fracture via blunt guillotine. Animals were euthanized at specific time points after injury. Serum and lung tissue were collected, and 24 inflammatory markers were analyzed by immunoassay. Lung histology was evaluated by a blinded pathologist.Results: Bilateral femur fracture significantly increased serum markers of inflammation including interleukin (IL-2, IL-6, IL-10, GM-CSF, KC/GRO, MCP-1, and WBC. Femur fracture ­significantly increased serum and lung levels of IL-1a and KC/GRO at 6 hours. Lung levels of IL-6 ­demonstrated a trend towards significance. Histologic changes in pulmonary tissue after fracture included pulmonary edema and bone elements including cellular hematopoietic cells, bone fragments and marrow emboli.Discussion and conclusion: Our results indicate that bilateral femur fracture with fixation in rats results in increases in serum markers of inflammation. Among the inflammatory markers measured, rise in the serum KC/GRO (CINC-1, a homolog to human IL-8, correlated with elevated levels of lung KC/GRO. Ultimately, analysis of serum levels of KC/GRO (CINC-1, or human IL-8, may be a useful adjunct to guide clinical decisions regarding surgical timing.Keywords: blunt trauma, injury, cytokine, IL-8, bone marrow emboli

This study retrospectively analyzed the clinicopathologic features of patients with any operable stage of NSCLC to identify the prognostic factors that influence tumor recurrence, including intratumoral blood vessel invasion (IVI, tumor size, tumor necrosis, and nodal involvement. Methods: From January 2002 to December 2011, 227 consecutive patients were enrolled in this study. They were divided into two groups: the “no recurrence” group and the “recurrence” group. Recurrence-free survival was analyzed by multivariable Cox regression analysis, stratified by tumor staging, chemotherapy, and lymphatic invasion. Results: IVI, tumor necrosis, tumor diameter more than 5 cm, and nodal involvement were identified as independent prognostic factors of tumor recurrence. The hazard ratio (HR of patients with IVI was 2.1 times higher than that of patients without IVI (95% confident interval [CI]: 1.4–3.2 (P = 0.001.The HR of patients with tumor necrosis was 2.1 times higher than that of patients without tumor necrosis (95% CI: 1.3–3.4 (P = 0.001.

  15. Bilateral vagotomy or atropine pre-treatment reduces experimental diesel-soot induced lung inflammation

    International Nuclear Information System (INIS)

    To investigate the role of the vagus nerve in acute inflammatory and cardiorespiratory responses to diesel particulate (DP) in the rat airway, we measured changes in respiration, blood pressure and neutrophils in lungs of urethane anesthetized Wistar rats 6-h post-instillation of DP (500 μg) and studied the effect of mid-cervical vagotomy or atropine (1 mg kg-1) pre-treatment. In conscious rats, we investigated DP, with and without atropine pre-treatment. DP increased neutrophil level in BAL (bronchoalveolar lavage) fluid from intact anesthetized rats to 2.5 ± 0.7 x 106 cells (n = 8), compared with saline instillation (0.3 ± 0.1 x 106, n = 7; P 6 cells (n = 8; P 6 (n = 4; P 6, n = 4, was reduced by pre-treatment with atropine to 2.2 ± 1.2 x 106 cells, n = 3. Hyperventilation occurred 6 h after DP in anesthetized rats with intact vagi, but not in bilaterally vagotomized or atropine pre-treated animals and was abolished by vagotomy (P < 0.05, paired test). There were no significant differences in the other variables (mean blood pressure, heart rate and heart rate variability) measured before and 360 min after DP. In conclusion, DP activates a pro-inflammatory vago-vagal reflex which is reduced by atropine. Muscarinic ACh receptors in the rat lung are involved in DP-induced neutrophilia, and hence muscarinic antagonists may reduce airway and/or cardiovascular inflammation evoked by inhaled atmospheric DP in susceptible individuals

    2014-10-01

    Full Text Available Congenital Pulmonary Airway Malformations (CPAMs are abnormalities of lung parenchyma that are often diagnosed upon prenatal imaging as opposed to postnatal symptoms. With a clinical presentation identical to CPAMs, Pleuropulmonary Blastoma (PPB is a rare pulmonary neoplasm of highly malignant potential. We present a rare case of a female infant with a vague medical history of respiratory distress syndrome (RDS at birth, presenting with a tension pneumothorax at three months of age, thought initially to be secondary to CPAM, but found to be PPB upon surgical resection and histological analysis. PPB is a rare pulmonary neoplasm of childhood that originates from the primitive interstitium of the lung, resulting in lesions that can be highly malignant. It is classified as type I (cystic, type II (cystic/solid or type III (solid, with a progression of disease and worsening prognosis from type I to type III. Due to the cystic nature of CPAM and PPB it is difficult to differentiate on imaging alone; diagnosis must be made based on histological analysis. The highly malignant nature and potential for morbidity and mortality of PPB should make clinicians consider early resection of cystic lung lesions preferentially on an elective basis.

  17. Effect of 32P-colloid interstitial irradiation on the treatment of occult lymphatic metastasis during lung cancer resection

    International Nuclear Information System (INIS)

    Objective: To study the effectiveness of interstitial irradiation by 32P-colloid on the occult metastasis during lung cancer resection. Methods: Seventy-three patients with lung cancer underwent resection of the tumor and interstitial administration of 32P-colloid. At the same period, 58 matched patients underwent surgical therapy only and served as the control group. After operation the dynamic distribution of body surface 32P-colloid activity, incidence of complications, rates of supra-clavicular lymph node (SCL) metastasis in different pathologic patterns, and survival rates at 1, 3, 5 years after treatment were studied. Results: No operative death occurred in these two groups. The incidences of lymph node metastasis and the incidences of major complications after operation were of no prominent differences between these two groups (χ2=0.012, 2.082, 0.003, P>0.05; χ2=0.021-0.144, P>0.05). The incidence of post-operative SCL metastasis in surgery plus 32P-colloid group was prominently lower than that in control group (χ2=4.507-5.348, P2=0.659, P>0.05), but the differences of the 3-, 5-year survial rates between the groups were prominent (χ2=4.207, 3.997, P32P-colloid during resection of lung cancer is a safe and effective procedure for controlling the occult lymphatic metastatic lesions and diminishing the focal relapse and distant metastasis, and it is bound to prolong the survival time of the patients.

  19. Efficacy of total lymphoid irradiation for chronic allograft rejection following bilateral lung transplantation

    International Nuclear Information System (INIS)

    Purpose: To assess the safety and efficacy of total lymphoid irradiation (TLI) in patients experiencing chronic rejection following bilateral lung transplantation (BLT). Patients and Materials: Eleven patients received TLI for chronic allograft rejection (bronchiolitis obliterans syndrome) refractory to conventional treatment modalities. Radiation therapy (RT) was prescribed as 8 Gy delivered in 10 0.8-Gy fractions, 2 fractions/week, via mantle, paraaortic, and inverted-Y fields. Serial pre- and post-RT pulmonary function values, complete blood counts, and immunosuppressive augmentation requirements [use of methylprednisolone, murine anti-human mature T-cell monoclonal antibody (OKT3), polyclonal antithymocyte globulin (ATG), and tacrolimus] were monitored. Results: In the 3 months preceding TLI, the average decrease in forced expiratory volume in 1 s (FEV1) was 34% (range 0-75%) and the median number of immunosuppression augmentations was 3 (range 0-5). Only 4 of 11 patients completed all 10 TLI treatment fractions. Reasons for discontinuation included progressive pulmonary decline (four patients), worsening pulmonary infection (two patients), and persistent thrombocytopenia (one patient). Seven of the 11 patients failed within 8 weeks of treatment cessation. One patient had unabated rejection and received bilateral living related-donor transplants; he is alive and well. Six patients died. Two of these deaths were due to pulmonary infection from organisms isolated prior to the start of RT; the other four deaths were from progressive pulmonary decline. The four remaining patients had durable positive responses to TLI (mean follow-up of 47 weeks; range 24-72). Comparing the 3 months preceding RT to the 3 months following treatment, these four patients had improvements in average FEV1 (40% decline vs. 1% improvement) and fewer median number of immunosuppressive augmentations (3.5 vs. 0). None of these patients has developed lymphoproliferative disease or has died

  20. Failure Rates and Patterns of Recurrence in Patients With Resected N1 Non-Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To examine the local and distant recurrence rates and patterns of failure in patients undergoing potentially curative resection of N1 non-small-cell lung cancer. Methods and Materials: The study included 60 consecutive unirradiated patients treated from 2000 to 2006. Median follow-up was 30 months. Failure rates were calculated by the Kaplan-Meier method. A univariate Cox proportional hazard model was used to assess factors associated with recurrence. Results: Local and distant failure rates (as the first site of failure) at 2, 3, and 5 years were 33%, 33%, and 46%; and 26%, 26%, and 32%, respectively. The most common site of local failure was in the mediastinum; 12 of 18 local recurrences would have been included within proposed postoperative radiotherapy fields. Patients who received chemotherapy were found to be at increased risk of local failure, whereas those who underwent pneumonectomy or who had more positive nodes had significantly increased risks of distant failure. Conclusions: Patients with resected non-small-cell lung cancer who have N1 disease are at substantial risk of local recurrence as the first site of relapse, which is greater than the risk of distant failure. The role of postoperative radiotherapy in such patients should be revisited in the era of adjuvant chemotherapy.

  1. The value of performing head CT in screening for cerebral metastases in patients with potentially resectable non-small cell lung cancer: experience from a UK cardiothoracic centre

    International Nuclear Information System (INIS)

    AIM: To evaluate the whether screening for cerebral metastases in neurologically intact patients with potentially resectable non-small cell lung cancer patients is both worthwhile and cost-effective. METHODS: We prospectively performed computed tomography (CT) of the head in 105 consecutive patients with potentially resectable lung cancer over an 18-month period. None of these patients had neurological symptoms or signs. RESULTS: Five patients (4.8%) with cerebral metastases were identified using CT. At our institution the financial saving of avoiding five thoracotomies was 45,000 Pounds, whilst the cost of performing 105 head CTs was 16,000 Pounds. This represented a substantial saving for the healthcare provider and preserved the quality of life in five patients. CONCLUSIONS: We conclude that screening for cerebral metastases in neurologically intact patients with potentially resectable non small cell lung cancer patients is both worthwhile and cost effective

    This study was conducted to observe the outcomes of postoperative radiotherapy (PORT) with or without concurrent chemotherapy in resected non-small cell lung cancer (NSCLC) in single institution. From 2002 to 2013, 78 patients diagnosed with NSCLC after curative resection were treated with radiotherapy alone (RT, n = 48) or concurrent chemoradiation (CCRT, n = 30). The indications of adjuvant radiation therapy were N2 node positive (n = 31), close or involved resection margin (n = 28), or gross residual disease due to incomplete resection (n = 19). The median radiation dose was 57.6 Gy (range, 29.9 to 66 Gy). Median survival time was 33.7 months (range, 4.4 to 140.3 months). The 5-year overall survival (OS) rate was 49.5% (RT 46% vs. CCRT 55.2%; p = 0.731). The 3-year disease-free survival rate was 45.5% (RT 39.4% vs. CCRT 55.3%; p = 0.130). The 3-year local control rate was 68.1% (RT 64.4% vs. CCRT 77.7%; p = 0.165). The 3-year DMFS rate was 56.1% (RT 52.6% vs. CCRT 61.7%; p = 0.314). In multivariate analysis, age > or =66 years and pathologic stage III were significant poor prognostic factors for OS. Treatment failure occurred in 40 patients. Four patients had radiologically confirmed grade 3 radiation pneumonitis. In NSCLC, adjuvant RT or CCRT after curative surgery is a safe and feasible modality of treatment. OS gain was seen in patients less than 66 years. Postoperative CCRT showed a propensity of achieving better local control and improved disease-free survival compared to RT alone according to our data.

  3. Quantitative evaluation of regional pulmonary functions after lung resection using three-dimensional images of ventilation and perfusion SPECT

    International Nuclear Information System (INIS)

    In 60 patients who underwent lung resection, ventilation (99mTc-phytate aerosol inhalation) and perfusion (99mTc-MAA) SPECT were performed before and one month after surgery. 3-D images were obtained from SPECT by the volume-rendering method setting thresholds at three levels, and the 3-D functional capacity of the right and left lung was determined at a threshold of 25%. Changes were evaluated using the ratio of the value obtained after surgery to the one obtained before surgery. The remaining rate of perfusion in the remaining lung was 0.58±0.22 after the right upper lobectomy, 0.32±0.04 after the right upper and middle bilobectomy, 0.86±0.11 after the right middle lobectomy, 0.55±0.17 after the right lower lobectomy, 0.24±0.18 after the left upper lobectomy, 0.46±0.05 after the left lower lobectomy, and 0 after the left pneumonectomy. The remaining rate was significantly low in the right upper and middle bilobectomy and the left upper lobectomy. The large decrease in the rate in these operations was considered to have resulted from a shift of the remaining lung towards the head and excessive expansion of the remaining lung. The distribution of the aerosol inhalation decreased more significantly than that of perfusion in almost all patients. The remaining rate of ventilation of the remaining lung after the lower lobectomy was lower than that after the upper lobectomy. This may have been due to the characteristics of the aerosol particles. This analysis is usefulness in evaluation of function preservation surgery. (K.H.)

  4. Patterns of Local-Regional Failure in Completely Resected Stage IIIA(N2) Non-Small Cell Lung Cancer Cases: Implications for Postoperative Radiation Therapy Clinical Target Volume Design

    International Nuclear Information System (INIS)

    Purpose: To analyze patterns of local-regional failure (LRF) for completely resected stage IIIA(N2) non-small cell lung cancer (NSCLC) patients treated in our hospital and to propose a clinical target volume (CTV) for postoperative radiation therapy (PORT) in these patients. Methods and Materials: From 2005 to 2011, consecutive patients with pT1-3N2 NSCLC who underwent complete resection in our hospital but who did not receive PORT were identified. The patterns of first LRF were assessed and evaluated as to whether these areas would be encompassed by our proposed PORT CTV. Results: With a median follow-up of 24 months, 173 of 250 patients (69.2%) experienced disease recurrence. Of the 54 patients with LRF as the first event, 48 (89%) had recurrence within the proposed PORT CTV, and 6 (11%) had failures occurring both within and outside the proposed CTV (all of which occurred in patients with right-lung cancer). Ninety-three percent of failure sites (104 of 112) would have been contained within the proposed PORT CTV. For left-sided lung cancer, the most common lymph node station failure site was 4R, followed by 7, 4L, 6, 10L, and 5. For right-sided lung cancer, the most common site was station 2R, followed by 10R, 4R, and 7. Conclusions: LRF following complete surgery was an important and potentially preventable pattern of failure in stage IIIA(N2) patients. Ipsilateral superior mediastinal recurrences dominated for right-sided tumors, whereas left-sided tumors frequently involved the bilateral superior mediastinum. Most of the LRF sites would have been covered by the proposed PORT CTV. A prospective investigation of patterns of failure after PORT (following our proposed CTV delineation guideline) is presently underway and will be reported in a separate analysis

    2007-01-01

    Objective: To evaluate the effect of postoperative adjuvant chemotherapy on survival after complete resection of stage Ⅲ-N2 non-small-cell lung cancer. Methods: From Jan. 1999 to Dec. 2003, one-hundred and fifty patients, who were diagnosed as stage Ⅲ-N2 non-small cell lung cancer after operation, were randomly devided into chemotherapy group and control group. The former received four cycles of chemotherapy with NVB (25 mg/m2,D1, D5)/paclitaxel (175 mg/m2, DI) and Carboplatin (AUC=5, D1). Results: In chemotherapy group, 75.8% (68/79) of patients had finished the 4 cycles of chemotherapy and no one died of toxic effects of chemotherapy.Twenty-five percent of the patients had grade 3-4 neutropenia and 2% had febrile neutropenia. The median survival for the entire 150 patients was 879 d, with 1-year survival rate of 81%, 2-year survival rate of 59% and 3-year survival rate of 43%. There was no significant difference in median survival between chemotherapy and control group (897 d vs 821 d, P=0.0527), but there was significant difference in the 1-year and 2-year overall survival (94.71%, 76.28% vs 512 d, P=0.122), but there was significant difference in the 2-year survival rate between two groups with brain metastases (66.7% vs 37.6% P<0.05). The median survival after brain metastasis appeared was 190 days. Conclusion: Postoperative adjuvant chemotherapy does not significantly improve median survival among patients with completely resected stage Ⅱ-N2 non-small-cell lung cancer, but significantly improves the 1-year and 2-year overall survival. It neither decreases the incidence of brain metastasis but put off the time of brain metastasis.

    Background:Despite numerous previous studies, the consideration of tumor location as a prognostic factor in resectable non–small cell lung cancer (NSCLC) remains controversial. The present study analyzed the association between tumor location and clinical outcome in patients with resectable NSCLC who had undergone lobectomy with systematic lymphadenectomy and who had presented with varying nodal statuses. Methods:The data from a cohort of 627 eligible patients treated in Sun Yat‑sen University Cancer Center between January 2000 and December 2008 were retrospectively collected, and the nodal statuses of patients with different tumor locations were compared. Cox proportional hazards regression model was used to determine the independent factors related to cancer‑speciifc survival (CSS). Results:Multivariate analysis demonstrated that left lower lobe (LLL) tumors [hazard ratio (HR): 1.465, 95% conif‑dence interval (CI) 1.090–1.969,P= 0.011], lymph node metastasis (HR: 2.742, 95% CI 2.145–3.507,P 4cm (HR: 1.474, 95% CI 1.151–1.888,P= 0.002) were three independent prognosticators in patients with resectable NSCLC. However, LLL tumors were associated only with CSS in node‑positive patients (HR: 1.528, 95%CI 1.015–2.301,P= 0.042), and a tumor size of >4cm was the only independent risk predictor in the node‑negative subgroup (HR: 1.889, 95% CI 1.324–2.696,P Conclusions:Tumor location is related to the long‑term CSS of NSCLC patients with lymph node metastasis. LLL tumors may be upstaged in node‑positive patients to facilitate an optimal treatment strategy.

    A 65-year-old man with right central type of lung squamous carcinoma was admitted to our department. Bronchoscopy displayed complete obstruction of right upper lobe bronchus and infiltration of the bronchus intermedius with tumor. Chest contrast computed tomography revealed the tumor invaded right pulmonary artery, superior vena cava, and the persistant left superior vena cava flowed into the coronary sinus. The tumor was successfully removed by means of bronchial and pulmonary artery sleeve resection of the right upper and middle lobes combined with resection and reconstruction of superior vena cava (SVC) utilizing ringed polytetrafluoroethylene graft. To the best of our knowledge, this was the first report of complete resection of locally advanced lung cancer involving superior vena cava, right pulmonary artery trunk and main bronchus with persistant left superior vena cava.

    A prospective analysis of results of combined treatment of 22 patients with central stage II-III non-small cell lung cancer (NSCLC) was performed (the defeat of the main bronchi or lower parts of the trachea), which initially had been regarded as unresectable or inoperable (12 patients for functional reasons could not pass pneumonectomy, and in 10 patients a contraindication to primary surgery was the involvement of the distal trachea in tumor), but underwent surgery after preoperative treatment.Combination therapy included preoperative endobronchial photodynamic therapy (PDT) and chemotherapy followed by surgery and intraoperative PDT resection margins. PDT was carried out with the use of chlorine E6 (Radachlorin) and light wavelength of 662 nm. Overall response rate after neoadjuvant treatment was 82 %, endoscopic remission was observed in 21 of 22 patients (95%). 10 patients underwent pneumonectomy, 12--lobectomy. 19 surgical interventions were regarded as radical (R0--86%), 3--as microscopically non-radical (R1--14%). Degree of lymphatic metastasis spreading pN0 was detected in 6 patients (27 %), pN1--in 14 (64%) and pN2--in 2 patients (9%). Surgical lethality was 5%. In the late time of the whole observation period none of the patients developed local recurrence. One-year survival was 95%, 3-year--91%. PDT can play an important role in combination with surgical treatment for NSCLC and reduces the amount of resection in part of initially unresectable or inoperable patients. PMID:24624784

    Acute kidney injury (AKI) is a serious problem in critically ill patients of intensive care units. It has been reported previously that AKI can induce acute lung injury (ALI), as well as cause injuries to other remote organs, including the lungs. Patients with AKI complicated by ALI show remarkably high mortality. ALI is characterized by neutrophil infiltration into the lung. Neutrophil elastase (NE) is a key enzyme for tissue injury caused by activated neutrophils, such as occurs in ALI. The...

    @@ Lung transplantation has been performed internationally as an effective treatment for a variety of end-stage lung diseases. A great disparity between the supply of donor organs and the demand of potential recipients has resulted in longer waiting time and annual increases in deaths on the lung transplant waiting list. Living-donor lobar lung transplantation (LDLLT) has become an established strategy to deal with the shortage of cadaveric donors. Encouraged by Starnes et al1 and Date et al,2 we began to apply the operation to a critically ill patient with bronchopulmonary dysplasia (BPD) firstly at Shanghai Pulmonary Hospital in China.

    Purpose: Current National Comprehensive Cancer Network guidelines recommend postoperative radiation therapy (PORT) for patients with resected non-small cell lung cancer (NSCLC) with N2 involvement. We investigated the relationship between nodal stage and local-regional recurrence (LR), distant recurrence (DR) and overall survival (OS) for patients having an R0 resection. Methods and Materials: A multi-institutional database of consecutive patients undergoing R0 resection for stage I-IIIA NSCLC from 1995 to 2008 was used. Patients receiving any radiation therapy before relapse were excluded. A total of 1241, 202, and 125 patients were identified with N0, N1, and N2 involvement, respectively; 161 patients received chemotherapy. Cumulative incidence rates were calculated for LR and DR as first sites of failure, and Kaplan-Meier estimates were made for OS. Competing risk analysis and proportional hazards models were used to examine LR, DR, and OS. Independent variables included age, sex, surgical procedure, extent of lymph node sampling, histology, lymphatic or vascular invasion, tumor size, tumor grade, chemotherapy, nodal stage, and visceral pleural invasion. Results: The median follow-up time was 28.7 months. Patients with N1 or N2 nodal stage had rates of LR similar to those of patients with N0 disease, but were at significantly increased risk for both DR (N1, hazard ratio [HR] = 1.84, 95% confidence interval [CI]: 1.30-2.59; P=.001; N2, HR = 2.32, 95% CI: 1.55-3.48; P<.001) and death (N1, HR = 1.46, 95% CI: 1.18-1.81; P<.001; N2, HR = 2.33, 95% CI: 1.78-3.04; P<.001). LR was associated with squamous histology, visceral pleural involvement, tumor size, age, wedge resection, and segmentectomy. The most frequent site of LR was the mediastinum. Conclusions: Our investigation demonstrated that nodal stage is directly associated with DR and OS but not with LR. Thus, even some patients with, N0-N1 disease are at relatively high risk of local recurrence. Prospective

    We present the first reported case of lung large cell neuroendocrine carcinoma (LCNEC) with spontaneous regression followed by progression. An 85-year-old woman presented with a 2.8-cm nodule in the right upper lung lobe on chest computed tomography. After four months, the tumor decreased to 1.8 cm and remained unchanged in size for the next three months, but it grew to 8.6 cm and invaded the mediastinal fat tissue after approximately one year. Ultrasound echo-guided percutaneous biopsy revealed the tumor to be LCNEC. The patient underwent a right upper lobectomy with lymph node dissection. She had a good postoperative course with no complications. Physicians and surgeons should be aware that radiographic regression of a pulmonary nodule does not necessarily exclude the possibility of lung cancer. PMID:26443884

Methods: PD-L1 and PD-L2 expression was measured by immunohistochemistry in 143 surgically resected lung adenocarcinomas and was correlated with clinical variables, histologic subtypes, and the mutational status of EGFR, KRAS, HER2, and ALK.Results: Positive PD-L1 expression was significantly associated with more advanced T status, N status, and pathologic stage. Histologically, lung adenocarcinomas with positive PD-L1 staining were less likely to be adenocarcinoma in situ or minimally invasive adenocarcinoma and more likely to have solid predominant subtype. Both PD-L1 expression (odds ratio =1.984, 95% confidence interval =1.010–3.894; P=0.047 and PD-L2 expression (odds ratio =2.328, 95% confidence interval =1.201–4.512; P=0.012 were independent predictors of poor overall survival. When the combined PD-L expression and pathologic stage were used together to predict overall survival, the concordance index increased to 0.763, and the Akaike information criteria value decreased to 356.08.Conclusion: We defined the clinicopathologic features of lung adenocarcinomas with high expression of PD-L1 and PD-L2.

    International Nuclear Information System (INIS)

    The predictive value of staging of primary lung cancer by CT and thoracotomy with respect to survival was assessed in a series of 151 consecutive patients. The new international staging system for lung cancer was used, with an additional indeterminate stage employed for cases in which a definite classification was impossible by CT. The survival rate curves for the stage groups assessed at CT and thoracotomy showed moderate to good parallelism. The patients with tumor stage I at thoracotomy but indeterminate or IIIa at CT had a significantly lower survival rate than those scored stage I at both. It was concluded that a sign of tumor spread obtained at any of the investigations should lead to an active approach, increasing the radicality of surgery or omitting noncurative operations. (orig.)

The aim of this study is to retrospectively associate ever tested IHC markers and prognosis of NSCLC after resection. Methods A total of 722 NSCLC patients underwent surgery by single surgeon team from 2008 to 2013. Twelve molecular markers had been examined by IHC and the staining signals was re-scored with unified standard. Survival analysis by univariate and multivariate was carried out to assess the significance of these markers in prognosis of NSCLC in our prospective database with strict follow-up. Results The following twelve IHC markers had been tested between 2008 and 2013, including platelet-derived growth factor receptor (PDGFR(n=124, excision repair cross complementing 1 (ERCC1(n=124, epithelial growth factor receptor (EGFR(n=131, vascular endothelial growth factor receptor 3 (VEGFR3(n=142, NM23 (n=129, MRP (n=109, P170 (n=104, TS (n=143, Tubulin (n=133, ribonucleotide reductase M1 (RRM1(n=131, ribonucleotide reductase M1 (COX2(n=138, and TOPII (n=127.

    Full Text Available Abstract Background Brain metastases (BM is one of the most common failures of locally advanced non-small cell lung cancer (LA-NSCLC after combined-modality therapy. The outcome of trials on prophylactic cranial irradiation (PCI has prompted us to identify the highest-risk subset most likely to benefit from PCI. Focusing on patients with completely resected pathological stage IIIA-N2 (pIIIA-N2 NSCLC, we aimed to assess risk factors of BM and to define the highest-risk subset. Methods Between 2003 and 2005, the records of 217 consecutive patients with pIIIA-N2 NSCLC in our institution were reviewed. The cumulative incidence of BM was estimated using the Kaplan–Meier method, and differences between the groups were analyzed using log-rank test. Multivariate Cox regression analysis was applied to assess risk factors of BM. Results Fifty-three (24.4 % patients developed BM at some point during their clinical course. On multivariate analysis, non-squamous cell cancer (relative risk [RR]: 4.13, 95 % CI: 1.86–9.19; P = 0.001 and the ratio of metastatic to examined nodes or lymph node ratio (LNR ≥ 30 % (RR: 3.33, 95 % CI: 1.79–6.18; P = 0.000 were found to be associated with an increased risk of BM.

The cumulative incidence of BM was estimated using the Kaplan–Meier method, and differences between the groups were analyzed using log-rank test. Multivariate Cox regression analysis was applied to assess risk factors of BM. Fifty-three (24.4 %) patients developed BM at some point during their clinical course. On multivariate analysis, non-squamous cell cancer (relative risk [RR]: 4.13, 95 % CI: 1.86–9.19; P = 0.001) and the ratio of metastatic to examined nodes or lymph node ratio (LNR) ≥ 30 % (RR: 3.33, 95 % CI: 1.79–6.18; P = 0.000) were found to be associated with an increased risk of BM. In patients with non-squamous cell cancer and LNR ≥ 30 %, the 5-year actuarial risk of BM was 57.3 %. In NSCLC, patients with completely resected pIIIA-N2 non-squamous cell cancer and LNR ≥ 30 % are at the highest risk for BM, and are most likely to benefit from PCI.

  8. Is the predicted postoperative FEV1 estimated by planar lung perfusion scintigraphy accurate in patients undergoing pulmonary resection? Comparison of two processing methods

    International Nuclear Information System (INIS)

    Estimation of postoperative forced expiratory volume in 1 s (FEV1) with radionuclide lung scintigraphy is frequently used to define functional operability in patients undergoing lung resection. We conducted a study to outline the reliability of planar quantitative lung perfusion scintigraphy (QLPS) with two different processing methods to estimate the postoperative lung function in patients with resectable lung disease. Forty-one patients with a mean age of 57±12 years who underwent either a pneumonectomy (n=14) or a lobectomy (n=27) were included in the study. QLPS with Tc-99m macroaggregated albumin was performed. Both three equal zones were generated for each lung [zone method (ZM)] and more precise regions of interest were drawn according to their anatomical shape in the anterior and posterior projections [lobe mapping method (LMM)] for each patient. The predicted postoperative (ppo) FEV1 values were compared with actual FEV1 values measured on postoperative day 1 (pod1 FEV1) and day 7 (pod7 FEV1). The mean of preoperative FEV 1 and ppoFEV1 values was 2.10±0.57 and 1.57±0.44 L, respectively. The mean of Pod1FEV1 (1.04±0.30 L) was lower than ppoFEV1 (p0.05). PpoFEV1 values predicted by both the zone and LMMs overestimated the actual measured lung volumes in patients undergoing pulmonary resection in the early postoperative period. LMM is not superior to ZM. (author)

    moderately increasing the depth of sedation while maintaining spontaneous breathing. Finally, as long as the physiologic impact of awake metastasectomy is definitively elucidated, the authors believe this modality should be used for unilateral procedures, while deserving a staged bilateral approach for bilateral lung metastasectomy. Avoidance of general anesthesia results in a faster recovery with immediate return to many daily life activities, including drinking, eating, and walking, and a reduction in hospital stay and procedure-related costs. If confirmed with future studies, these results could advocate earlier resection of peripheral solitary pulmonary nodules, reducing the risk for delaying a diagnosis of unexpected pulmonary malignancy. Furthermore, potential new frontiers of awake thoracoscopic surgery might include assessment of feasibility and safety of anatomic resections in properly selected instances. Ethical and economical concerns push remorselessly for less frequent and less-invasive surgery. Administrators advocate minimal hospitalization and cost-saving treatments, whereas patients ultimately ask for appropriate health care. Thoracic surgeons of the third millennium must accept the challenge of this dynamic and rapidly evolving scenario without loosing the right root, which probably lays just between well-established conventional surgery techniques and newly available advanced technology tools. Awake thoracic surgery will benefit from evidence-based data that are progressively accumulating. Findings will stimulate experts to continue an active clinical investigation in this unpredictably evolving surgical field, which might ultimately lead to a better understanding of cardiorespiratory physiology and effects of the surgical pneumothorax and thoracic epidural anesthesia on perioperative, respiratory function in awake patients. As the Italian architect Renzo Piano recently stated, "Recovering in the past can be reassuring but the future is the only place

    Full Text Available Objective To explore the therapeutic effect and degree of safety in patients aged 80 years or over with nonsmall cell lung cancer undergoing radical resection. Methods A retrospective survey of 97 elder patients aged 80 years or over, in whom non-small cell lung cancer was pathologically confirmed after partial resection of the lung in Chinese PLA General Hospital from Jan. 2003 to Dec. 2012. The peri-operative features were evaluated, including gender, age, history of smoking, pulmonary function, surgical procedure, histopathologic type, pathologic stage, etc. The relation of the postoperative complications and mortality with the factors mentioned above was analyzed. Results Among all patients, the surgical procedure comprised 36 lobectomies, 31 segmentectomies, and 30 wedge resections. The histopathologic diagnosis showed there were adenocarcinoma in 51 patients, squamous cell carcinoma in 29, large cell carcinoma in 9, adenosquamous cell carcinoma in 6 and neuro-endocrine cell carcinomas in 2. The disease stage was determined as ⅠA in 55 cases, ⅠB in 33, ⅡA in 7, ⅢA in 2. The post-operative complications (POC occurred in 14 of 97 patients (14.4%, and the most common complication was cardiovascular complication (9 cases, followed by pulmonary complication (5 cases. Only two patients died to the complications, one of them was post-operative pneumonia and respiratory failure, and the other one was acute myocardial infarction. The survival rate of the 97 patients was 91.7%, 70.2% and 52.8% at 1, 3 and 5 years, respectively, and in the patients with stage I disease, the survival rate was 93.9%, 73.6% and 54.1%, respectively. Conclusion Advanced age is not a contraindication to radical pulmonary resection in patients over 80 years old suffering from early stage non-small cell lung cancer.

  12. Risk of acute exacerbation of interstitial pneumonia after pulmonary resection for lung cancer in patients with idiopathic pulmonary fibrosis based on preoperative high-resolution computed tomography

    International Nuclear Information System (INIS)

    In patients with lung cancer accompanied by idiopathic pulmonary fibrosis (IPF), acute exacerbation of the IPF often occurs after pulmonary resection; however, few studies have been done to identify its preexisting risk factors. We analyzed the high-resolution computed tomography (HRCT) findings of IPF to identify the radiological characteristics of IPF susceptible to acute exacerbation after lung cancer surgery. We reviewed retrospectively 28 lung cancer patients with IPF who underwent pulmonary resection. Clinical data, respiratory function, HRCT findings, and historical features were compared between the acute exacerbation (n=9) and nonexacerbation (n=19) groups. The classification of radiological findings of IPF on HRCT was done using a scoring system of seven factors related to the interstitial shadow, including fibrosis, ground-glass opacity, and low-attenuation area. There were no significant differences in clinical background, respiratory function, composite physiologic index, or pathological features between the groups; however, the degree of fibrosis on preoperative HRCT was significantly higher in the exacerbation group (P<0.003). The fibrosis score was higher on the opposite side to the lung cancer in the exacerbation group (P<0.05). Although it is difficult to predict postoperative acute IPF exacerbation, the degree and laterality of co-existing fibrosis seem to be predictors. (author)

    Full Text Available Published data suggests that wedge resection for stage I NSCLC results in improved overall survival compared to stereotactic body radiation therapy (SBRT. We report CyberKnife outcomes for high-risk surgical patients with biopsy-proven stage I NSCLC. PET/CT imaging was completed for staging. Three-to-five gold fiducial markers were implanted in or near tumors to serve as targeting references. Gross tumor volumes (GTVs were contoured using lung windows; the margins were expanded by 5 mm to establish the planning treatment volume (PTV. Treatment plans were designed using hundreds of pencil beams. Doses delivered to the PTV ranged from 42-60 Gy in 3 fractions. The 30-Gy isodose contour extended at least 1cm from the GTV to eradicate microscopic disease. Treatments were delivered using the CyberKnife system with tumor tracking. Examination and PET/CT imaging occurred at 3-month follow-up intervals. Forty patients (median age 76 with a median maximum tumor diameter of 2.6 cm (range, 1.4-5.0 cm and a mean post-bronchodilator percent predicted forced expiratory volume in 1 second (FEV1 of 57% (range, 21 - 111% were treated. A mean dose of 50 Gy was delivered to the PTV over 3 to 13 days (median, 7 days. The 30-Gy isodose contour extended a mean 1.9 cm from the GTV. At a median 44 months (range, 12 -72 months follow-up, the 3-year Kaplan-Meier locoregional control and overall survival estimates compare favorably with contemporary wedge resection outcomes at 91% and 75% , respectively. CyberKnife is an effective treatment approach for stage I NSCLC that is similar to wedge resection, eradicating tumors with 1 to 2 cm margins in order to preserve lung function. Prospective randomized trials comparing CyberKnife with wedge resection are necessary to confirm equivalence.

    Full Text Available Background and objective Lung cancer is the leading cause of cancer death in men and women in the world, more than one-half of cases are diagnosed at a advanced stage, and the overall 5-year survival rate for lung cancer is 18%. Lung cancer is divided into non-small cell lung carcinoma (NSCLC and small cell lung carcinoma (SCLC. Approximately 80%-85% of cases are NSCLC which includes three main types: adenocarcinoma (40%, squamous cell carcinoma (SCC (20%-30%, and large cell carcinoma (10%. Although therapies that target driver mutations in adenocarcinomas are showing some promise, they are proving ineffective in smoking-related SCC. We need pay more attention to the diagnosis and treatment of SCC. 18F-FDG positron emission tomography (PET/computed tomography (CT has emerged as an accurate staging modality in lung cancer diagnosis. The aim of this study is to investigate the role of maximum standardized uptake value (SUVmax on PET-CT in prognosis and its correlation with clinicopathological characteristics in resectable SCC. Methods One hundred and eighty-two resectable SCC patients who underwent PET/CT imaging between May 2005 and October 2014 were enrolled into this retrospectively study. All the enrolled patients had underwent pulmonary resection with mediastinal lymph node dissection without preoperative chemotherapy or radiotherapy. Survival outcomes were analyzed using the Kaplan-Meier method and multivariate Cox proportional hazards model. Correlation between SUVmax and clinicopathological factors was analysed using Pearson correlation analysis and Spearman rank correlation analysis. Results The patients were divided into two groups on the basis of SUVmax 13.0 as cutoff value, and patients with SUVmax more than 13.0 had shorter median overall survival than patients less than 13.0 in univariate analysis (56 months vs 87 months; P=0.022. There was remarkable correlation between SUVmax and gender, tumor size, tumor-node-metastasis (TNM stage

  17. An in-silico comparison of proton beam and IMRT for postoperative radiotherapy in completely resected stage IIIA non-small cell lung cancer

    International Nuclear Information System (INIS)

    Post-operative radiotherapy (PORT) for stage IIIA completely-resected non-small cell lung cancer (CR-NSCLC) has been shown to improve local control; however, it is unclear that this translates into a survival benefit. One explanation is that the detrimental effect of PORT on critical organs at risk (OARs) negates its benefit. This study reports an in-silico comparative analysis of passive scattering proton therapy (PSPT)- and intensity modulated proton therapy (IMPT) with intensity modulated photon beam radiotherapy (IMRT) PORT. The computed tomography treatment planning scans of ten patients with pathologic stage IIIA CR-NSCLC treated with IMRT were used. IMRT, PSPT, and IMPT plans were generated and analyzed for dosimetric endpoints. The proton plans were constructed with two or three beams. All plans were optimized to deliver 50.4 Gy(RBE) in 1.8 Gy(RBE) fractions to the target volume. IMPT leads to statistically significant reductions in maximum spinal cord, mean lung dose, lung volumes treated to 5, 10, 20, and 30 Gy (V5, V10, V20, V30), mean heart dose, and heart volume treated to 40 Gy (V40), when compared with IMRT or PSPT. PSPT reduced lung V5 but increased lung V20, V30, and heart and esophagus V40. IMPT demonstrates a large decrease in dose to all OARs. PSPT, while reducing the low-dose lung bath, increases the volume of lung receiving high dose. Reductions are seen in dosimetric parameters predictive of radiation pneumonitis and cardiac morbidity and mortality. This reduction may correlate with a decrease in dose-limiting toxicity and improve the therapeutic ratio

Surgical resection is the preferred treatment for brain metastases. However, no studies have reported the outcome of surgical resection of brain metastases from non–small-cell lung cancer (NSCLC in the People’s Republic of China. Moreover, the optimal treatment for primary NSCLC in patients with synchronous brain metastases is hitherto controversial. Patients and methods: We retrospectively analyzed the cases of NSCLC patients with brain metastases who underwent neurosurgical resection at the Sun Yat-sen University Cancer Center, and assessed the efficacy of surgical resection and the necessity of aggressive treatment for primary NSCLC in synchronous brain metastases patients. Results: A total of 62 patients, including 47 men and 15 women, with brain metastases from NSCLC were enrolled in the study. The median age at the time of craniotomy was 54 years (range 29–76 years. At the final follow-up evaluation, 50 patients had died. The median OS time was 15.1 months, and the survival rates were 70% and 37% at 1 and 2 years, respectively. The median OS

    A 68-year old man with a cardiac tumour was admitted for robotic tumour resection using the da Vinci S Surgical System. While undergoing preoperative examination, he was found to have a persistent left superior vena cava. After general anaesthesia and single-lung ventilation, cardiopulmonary bypass was established, with venous drainage through bilateral internal jugular and right femoral veins and arterial return through the right femoral artery. Robotic tumour resection was performed by four ports in the right chest. There were no difficulties during the operation, and successful tumour resection was achieved with satisfactory margins. He was discharged without complications. Persistent left superior vena cava is very rare, but if diagnosed preoperatively and an appropriate operative plan is made, robotic cardiac surgery can be performed safely. With robotic surgery, cardiac tumour resection can be feasibly performed, with cosmetic benefits. PMID:26989070

  1. Risk factors for brain metastases in completely resected small cell lung cancer: a retrospective study to identify patients most likely to benefit from prophylactic cranial irradiation

    International Nuclear Information System (INIS)

    The role of prophylactic cranial irradiation (PCI) on small cell lung cancer (SCLC) has been established based on the two-stage system of limited versus extensive disease and the treatment modality of chemoradiotherapy. However, the use of PCI after combined-modality treatment with surgery for resectable limited-stage SCLC has not been investigated sufficiently. We conducted a retrospective study to evaluate risk factors for brain metastasis (BM) in patients with surgically resected SCLC to identify those most likely to benefit from PCI. The records of 126 patients with completely resected SCLC and definitive TNM stage based on histological examination between 2003 and 2009 were reviewed. The cumulative incidence of BM was estimated using the Kaplan–Meier method and differences between the groups were analyzed using the log-rank test. Multivariate Cox regression analysis was applied to assess the risk factors of BM. Twenty-eight patients (22.2%) developed BM at some point during their clinical course. The actuarial risk of developing BM at 3 years was 9.7% in patients with p-stage I disease, 18.5% in patients with p-stage II disease, and 35.4% in patients with p-stage III disease (p = 0.013). The actuarial risk of developing BM at 3 years in patients with LVI was 39.9% compared to 17.5% in patients without LVI (p = 0.003). Multivariate analysis identified pathologic stage (hazard ratio [HR] = 2.013, p = 0.017) and LVI (HR = 1.924, p = 0.039) as independent factors related to increased risk of developing BM. Patients with completely resected p-stage II-III SCLC and LVI are at the highest risk for BM

    Full Text Available Background and objective Despite undergoing curative resection, the 5-year survival rate for stage III non-small cell lung cancer (NSCLC patients is less than 25%. There is a need for biomarkers for prediction of survival and guiding individual therapy. MiR-155 is one of most commonly upregulated miRNAs in malignancies, and regulates multiple pro-oncogenic pathways. We aimed to investigate the prognostic impact of miR-155 in resected stage III NSCLC patients. Methods Tumor formalin-fixed, paraffin-embedded (FFPE from 162 resected stage III NSCLC patients were collected. Total RNA including miRNA was extracted, and qRT-PCR was used to determine the expression of miR-155. Results Spearman rank correlation test showed a positive correlation between miR-155 expression and nodal status (r=0.169, P=0.032. MiR-155 expression had a significant prognostic impact in the total cohort (P<0.001, in squamous cell carcinomas (P=0.002 and in adenocarcinomas (P=0.003. In N0-1 subgroup, miR-155 expression did not have a significant prognostic on overall survival in univariate analysis (P=0.319. In N2 subgroup, miR-155 had a negative prognostic effect on OS in univariate analysis (P<0.001. Cox regression analysis revealed that miR-155 expression was unfavorable prognostic factors of OS (RR=2.311, 95%CI: 1.479-3.611, P<0.001. Conclusion High expression of miR-155 represents a valuable marker of poor clinical outcomes in patients with stage III NSCLC.

    We evaluated the prognostic significance of T3 subtypes and the role of adjuvant radiotherapy in patients with resected the American Joint Committee on Cancer stage IIB T3N0M0 non-small cell lung cancer (NSCLC). T3N0 NSCLC patients who underwent resection from January 1990 to October 2009 (n = 102) were enrolled and categorized into 6 subgroups according to the extent of invasion: parietal pleura chest wall invasion, mediastinal pleural invasion, diaphragm invasion, separated tumor nodules in the same lobe, endobronchial tumor <2 cm distal to the carina, and tumor-associated collapse. The median overall survival (OS) and disease-free survival (DFS) were 55.3 months and 51.2 months, respectively. In postoperative T3N0M0 patients, the tumor size was a significant prognostic factor for survival (OS, p = 0.035 and DFS, p = 0.035, respectively). Patients with endobronchial tumors within 2 cm of the carina also showed better OS and DFS than those in the other T3 subtypes (p = 0.018 and p = 0.016, respectively). However, adjuvant radiotherapy did not cause any improvement in survival (OS, p = 0.518 and DFS, p = 0.463, respectively). Only patients with mediastinal pleural invasion (n = 25) demonstrated improved OS and DFS after adjuvant radiotherapy (n = 18) (p = 0.012 and p = 0.040, respectively). The T3N0 NSCLC subtype that showed the most favorable prognosis is the one with endobronchial tumors within 2 cm of the carina. Adjuvant radiotherapy is not effective in improving survival outcome in resected T3N0 NSCLC.

    2016-01-01

    We report a case of an undifferentiated pleomorphic sarcoma in a 73-year-old female, with a solitary lung metastasis involving the pericardium that progressed on first-line chemotherapy. Partial removal of the lesion was achieved after lingular segmentectomy, which required en-bloc pericardial resection due to deep pericardial invasion. However, the residual disease significantly grew despite second-line chemotherapy, and the tumor became unresectable due to near encasement of the left anterior descending coronary artery. Therefore, we opted for a salvage radical dose of intensity-modulated radiotherapy (60Gy in 25 fractions) to the pericardial lesion. No acute side effects were observed, and after three years of follow-up, good local control has been achieved with no significant late effects observed. This case suggests that radical radiotherapy using IMRT could be considered to treat sarcomatous pericardial lesions in patients who do not respond to chemotherapy and who are inoperable or non-resectable.

    Full Text Available Purpose: The main purpose of this study is to perform a treatment planning study on a synchronous bilateral non-small cell lung cancer case using three treatment modalities: uniform scanning proton therapy, RapidArc, and intensity modulated radiation therapy (IMRT. Methods: The maximum intensity projection (MIP images obtained from the 4 dimensional-computed tomography (4DCT scans were used for delineation of tumor volumes in the left and right lungs. The average 4D-CT was used for the treatment planning among all three modalities with identical patient contouring and treatment planning goal. A proton therapy plan was generated in XiO treatment planning system (TPS using 2 fields for each target. For a comparative purpose, IMRT and RapidArc plans were generated in Eclipse TPS. Treatment plans were generated for a total dose of 74 CGE or Gy prescribed to each planning target volume (PTV (left and right with 2 CGE or Gy per fraction. In IMRT and RapidArc plans, normalization was done based on PTV coverage values in proton plans. Results: The mean PTV dose deviation from the prescription dose was lower in proton plan (within 3.4%, but higher in IMRT (6.5% to 11.3% and RapidArc (3.8% to 11.5% plans. Proton therapy produced lower mean dose to the total lung, heart, and esophagus when compared to IMRT and RapidArc. The relative volume of the total lung receiving 20, 10, and 5 CGE or Gy (V20, V10, and V5, respectively were lower using proton therapy than using IMRT, with absolute differences of 9.71%, 22.88%, and 39.04%, respectively. The absolute differences in the V20, V10, and V5 between proton and RapidArc plans were 4.84%, 19.16%, and 36.8%, respectively, with proton therapy producing lower dosimetric values. Conclusion: Based on the results presented in this case study, uniform scanning proton therapy has a dosimetric advantage over both IMRT and RapidArc for a synchronous bi-lateral NSCLC, especially for the normal lung tissue, heart, and

    Full Text Available We aimed to reveal the true status of epidermal growth factor receptor (EGFR mutations in Chinese patients with non-small cell lung cancer (NSCLC after lung resections. EGFR mutations of surgically resected fresh tumor samples from 697 Chinese NSCLC patients were analyzed by Amplification Refractory Mutation System (ARMS. Correlations between EGFR mutation hotspots and clinical features were also explored. Of the 697 NSCLC patients, 235 (33.7% patients had tyrosine kinase inhibitor (TKIs sensitive EGFR mutations in 41 (14.5% of the 282 squamous carcinomas, 155 (52.9% of the 293 adenocarcinomas, 34 (39.5% of the 86 adenosquamous carcinomas, one (9.1% of the 11 large-cell carcinomas, 2 (11.1% of the 18 sarcomatoid carcinomas, and 2 (28.6% of the 7 mucoepidermoid carcinomas. TKIs sensitive EGFR mutations were more frequently found in female patients (p < 0.001, non-smokers (p = 0.047 and adenocarcinomas (p < 0.001. The rates of exon 19 deletion mutation (19-del, exon 21 L858R point mutation (L858R, exon 21 L861Q point mutation (L861Q, exon 18 G719X point mutations (G719X, including G719C, G719S, G719A were 43.4%, 48.1%, 1.7% and 6.8%, respectively. Exon 20 T790M point mutation (T790M was detected in 3 squamous carcinomas and 3 adenocarcinomas and exon 20 insertion mutation (20-ins was detected in 2 patients with adenocarcinoma. Our results show the rates of EGFR mutations are higher in all types of NSCLC in Chinese patients. 19-del and L858R are two of the more frequent mutations. EGFR mutation detection should be performed as a routine postoperative examination in Chinese NSCLC patients.

  8. The prognostic value of ERCC1 and RRM1 gene expression in completely resected non-small cell lung cancer: tumor recurrence and overall survival

    International Nuclear Information System (INIS)

    The roles of excision repair cross-complementing group 1 gene (ERCC1) expression and ribonucleotide reductase subunit M1 gene (RRM1) expression in completely resected non-small cell lung cancer (NSCLC) are still debatable. Previous studies have shown that both genes affected the overall survival and outcomes of patients who received platinum-based chemotherapy; however, some studies did not show this correlation. The aim of this study was to evaluate the prognostic values of ERCC1 and RRM1 gene expression in predicting tumor recurrence and overall survival in patients with completely resected NSCLC who received adjuvant chemotherapy and in those who did not. A retrospective cohort study was conducted in 247 patients with completely resected NSCLC. All patients had been treated with anatomic resection (lobectomy or pneumonectomy) with systematic mediastinal lymphadenectomy between January 2002 and December 2011 at Chiang Mai University Hospital, Chiang Mai, Thailand. They were divided into two groups: recurrence and no recurrence. Protein expression of ERCC1 and RRM1 was determined by immunohistochemistry. Correlations between clinicopathologic variables, including ERCC1 and RRM1 expression and tumor recurrence, were analyzed. Univariate and multivariate Cox proportional hazards regression analysis stratified by nodal involvement, tumor staging, intratumoral blood vessel invasion, intratumoral lymphatic invasion, and tumor necrosis was used to identify the prognostic roles of ERCC1 and RRM1. ERCC1 and RRM1 expression did not demonstrate prognostic value for tumor recurrence and overall survival in patients with completely resected NSCLC. In patients who did not receive adjuvant chemotherapy treatment, those with high ERCC1 and high RRM1 expression seemed to have greater potential for tumor recurrence and shorter overall survival than did those who had low ERCC1 and low RRM1 (hazard ratio [HR] =1.7, 95% confidence interval [CI] =0.6–4.3, P=0.292 and HR =1.6, 95% CI

    Full Text Available Abstract Background Lung transplantation (LTx is widely accepted as a therapeutic option for end-stage respiratory failure in cystic fibrosis. However, airway complications remain a major cause of morbidity and mortality in these patients, serious airway complications like bronchopleural fistula (BPF are rare, and their management is very difficult. Case presentation A 47-year-old man with end-stage respiratory failure due to cystic fibrosis underwent bilateral sequential lung transplantation. Severe post-operative bleeding occurred due to dense intrapleural adhesions of the native lungs. He was re-explored and packed leading to satisfactory haemostasis. He developed a bronchopleural fistula on the 14th post-operative day. The fistula was successfully repaired using pericardial and intercostal vascular flaps with veno-venous extracorporeal membrane oxygenator (VV-ECMO support. Subsequently his recovery was uneventful. Conclusion The combination of pedicled intercostal and pericardial flaps provide adequate vascular tissue for sealing a large BPF following LTx. Veno-venous ECMO allows a feasible bridge to recovery.

    In this manuscript, we present the first experience of evaluating donation after circulatory death (DCD) lungs, using the normothermic preservation Organ Care System (OCS) and subsequent successful transplantation. The OCS could be a useful tool for the evaluation of marginal lungs from DCD donors as it allows a proper recruitment and bronchoscopy in such donations in addition to continuous ex-vivo perfusion and assessment and treatment during transport. The OCS could potentially be a standard of care in the evaluation of marginal lungs from DCD. PMID:25332197

  12. Prognostic significance of the combined score of endothelial expression of nucleolin and CD31 in surgically resected non-small cell lung cancer.

    Full Text Available Nucleolin is implicated to play a role in angiogenesis, a vital process in tumor growth and metastasis. However, the presence and clinical relevance of nucleolin in human non small cell lung cancer (NSCLC remains largely unknown. In this study, we explored the expression and prognostic implication of nucleolin in surgically resected NSCLC patients. A cohort of 146 NSCLC patients who underwent surgical resection was selected for tissue microarray. In this tissue microarray, nucleolin expression was measured by immunofluorescence. Staining for CD31, a marker of endothelial cells, was performed to mark blood vessels. A Cox proportional hazards model was used to assess the prognostic significance of nucleolin. Nucleolin expression was observed in 34.2% of all patients, and 64.1% in high CD31 expression patients. The disease-free survival (DFS was significantly shorter in patients with high nucleolin (CD31(hiNCL(hi compared to patients with low tumor blood vessels (CD31(loNCL(lo (5 ys of DFS 24% vs 64%, p = 0.002. Such a difference was demonstrated in the following stratified analyses: stage I (p<0.001, squamous cell carcinoma and adenosquamous cell carcinoma (p = 0.028, small tumor (<5 cm, p = 0.008, and surgery alone (p = 0.015. Multivariate analysis further revealed that nucleolin expression independently predicted for worse survival (p = 0.003. This study demonstrates that nucleolin is associated with the clinical outcomes in postoperative NSCLC patients. Thus, the expression levels of nucleolin may provide a new prognostic marker to identify patients at higher risk for treatment failure, especially in some subgroups.

    Meandering pulmonary veins is a rare clinical entity that can be mistaken for more complex congenital syndromes such as hypogenetic lung syndrome. We report imaging findings in a rare incidentally detected case of bilateral meandering pulmonary veins. We briefly discuss the role of imaging in diagnosing this condition, with particular emphasis on contrast-enhanced CT. (orig.)

  15. Accuracy of helical computed tomography for the identification of lymph node metastasis in resectable non-small cell lung cancer

    International Nuclear Information System (INIS)

    The criteria for the diagnosis of lymph node metastasis (LNM) in non-small cell lung cancer were investigated using helical computed tomography (hCT). The conventional criterion (1-cm short axis threshold) is generally accepted; however, this criterion is based on conventional CT. New criteria for LNM were investigated because the resolution of hCT is better than that of conventional CT. Ninety-seven non-small cell lung cancer (NSCLC) patients examined with hCT were enrolled. Both the long axis (LA) and short axis (SA) of the nodes were measured using hCT. Based on the receiver operating characteristic curves, the thresholds that gave optimal sensitivity and specificity for LNM were 13 mm for LA and 9 mm for SA. The LNM diagnosis was re-evaluated using the combination of cutoff values. When the LA was ≥13 mm and the SA was ≥9 mm, the sensitivity, specificity, and accuracy were 56.3%, 92.1%, and 88.1%, respectively. When the LA was ≥13 mm or SA was ≥9 mm, sensitivity, specificity, and accuracy were 75.0%, 74.7%, and 74.7%, respectively. These values were not so different from the conventional criterion recalculated from these data. The new criteria are considered to be useful for making a LNM diagnosis. The conventional criteria for the LNM diagnosis might therefore be applicable even for hCT. (author)

    To understand the pathogenesis of high-grade neuroendocrine carcinoma (HGNEC), we examined the histopathology and immunoreactivity against adenocarcinoma (AD), squamous cell carcinoma (SQ), and neuroendocrine markers in 34 cases with combined HGNEC. The 5 year overall survival rates of patients with combined small cell carcinoma (SCC) (n = 9) and combined large cell neuroendocrine carcinoma (LCNEC) (n = 25) were 33% and 75%, respectively (P = 0.011). Most of the patients were male (94%), smokers (94%), and had tumors located in the peripheral (94%) and upper lobe (65%) of the lung. Histopathologically, non-HGNEC components were predominantly ADs (65%) followed by SQs (26%). In combined HGNEC and AD, a lepidic AD component was found in 12 cases (48%). For the HGNEC components of combined HGNEC and AD, the incidence of positivity of thyroid transcription factor-1 (TTF-1) (8G7G3/1) and TTF1 (SPT24) were 64% and 91%, respectively. For HGNEC components of combined HGNEC and SQ, the incidence of positivity of 34βE12 and p63 were 22% and 11%, respectively. In conclusion, 48% of combined HGNEC and AD cases had a lepidic AD component, suggesting that HGNEC can develop in association with pre-existing AD. AD markers, but not SQ markers, were frequently retained through development of the HGNEC component. PMID:24471967

  18. Thoracoscopic lung volume reduction surgery for emphysema. Evaluation using ventilation-perfusion scintigraphy

    International Nuclear Information System (INIS)

    Thoracoscopic lung volume reduction surgery was conducted in 28 consecutive patients (bilateral 21, unilateral 7). The bilateral procedure was conducted simultaneously in 16 and as a planned staged approach in 5, using stapler resection with Nd: YAG laser ablation. Perfusion and ventilation scintigraphy were used to evaluate status before and after surgery. One operative death (3.6%) due to pneumonia occurred after a simultaneous bilateral procedure. Three to 6 months after surgery, the forced expiratory volume in 1 second (FEV1.0) had improved an average of 44% after the bilateral procedure and 17% after unilateral. Improved ventilation and perfusion distribution in the lower lung field correlated significantly with improved dyspnea scale (p1.0 and maximum oxygen consumption (V'o2max) (p<0.05). In conclusion, we found that bilateral thoracoscopic lung volume reduction surgery produces short-term functional outcomes superior to those of the unilateral procedure, and should be considered the procedure of choice for most patients. Ventilation and perfusion scintigraphy are useful both in determining target areas for resection and in evaluating lung volume reduction surgery effects. (author)

    International Nuclear Information System (INIS)

    Background: In the German CESS-studies, Ewing's sarcoma patients with pulmonary metastases at diagnosis were considered as candidates for additional bilateral lung irradiation. We have retrospectively analyzed the impact of radiotherapy on survival. Material and methods: Out of 42 patients presenting with pulmonary metastases of Ewing's sarcoma between 1981 and June 1992, 30 were evaluable. One patient died of progressive disease prior to lung irradiation. The other patients had a complete radiographic remission either after chemotherapy (n=25) or chemotherapy plus resection of lung metastases (n=4). 22 patients received bilateral lung irradiation with doses of 12 to 21 Gy (once daily 1.5 Gy or twice daily 1.25 Gy), six had no further treatment and one had bone marrow transplantation for consolidation. Results: Ten patients are in complete remission, nine of them had received lung irradiation and one had a complete resection of three lung metastases. Two patients are alive with disease, two have died from treatment-related complications and 16 have died from systemic disease with or without local relapse. NED-patients had received significant higher lung doses than relapsed patients p=0.028. Moreover, a dose-response relationship was detectable: 1/6 patients without lung irradiation vs. 4/10 with 12 to 16 Gy vs. 5/6 with 18 to 21 Gy lung irradiation were in remission. (orig.)

    Full Text Available Acute dacryoadenitis is an uncommon condition that involves inflammation of the lacrimal gland. In rare instances, dacryoadenitis may be bilateral. A delay in proper treatment of an otherwise simple case of dacryoadenitis may lead to significant soft tissue morbidity such as cellulitis, lacrimal gland abscess, or orbital abscess. We report the case of a 24-year-old male who presented to the emergency department with acute bilateral dacryoadenitis. The patient′s symptoms did not respond to oral antibiotics and he subsequently required admission for intravenous antibiotics. During his hospitalization the patient had diagnostic testing to try to determine the etiology for his symptoms. The unique aspects of managing a case of bilateral dacryoadenitis as well as treatment recommendations are discussed in this case report.

  2. Concomitant bilateral testicular epidermoid cysts

    International Nuclear Information System (INIS)

    Epidermoid cyst of the testis is a rare benign germ tumor, comprising 1-2% of all resected benign testicular masses. Approximately 300 cases have been reported to date. Unilateral involvement has often been reported in the English literature. However, bilateral occurrence is very rare and to the best of our knowledge, there only 3 previous reports of bilateral testicular epidermoid cysts. The fact that they are completely benign makes them amenable to treatment by local excision, thereby saving patient from orchidectomy. Recognition of their characteristic ulatrsonographic features is very important to avoid unnecessary intervention. We present here, a case of bilateral epidermoid cyst in which characteristic ultrasound (US) findings allowed testis-sparing enucleation instead of radical orchiectomy. (author)

    Full Text Available Abstract Introduction The distant metastases from differentiated thyroid carcinomas are often untreatable. In particular, bone metastasis is significantly related to poor prognosis since radioactive iodine therapy is generally less effective. Therefore, surgical resection is considered one of the treatments for patients with bone metastases. We report chest wall resection and reconstruction using titanium micromesh covered with polypropylene mesh (Marlex mesh for metastatic rib bones as a result of follicular thyroid carcinoma. Case presentation A 51-year-old man was referred to our institution with a painful chest wall tumor. He presented with a 15 × 10 cm bony swelling on the left chest wall and multiple small lung nodules from follicular thyroid carcinoma. Completion total thyroidectomy, chest wall resection and reconstruction using titanium micromesh covered with Marlex mesh were performed. There were no critical complications associated with surgical treatments and tumor pain disappeared during the postoperative period. Then, he received radioactive iodine therapy and the uptake of radioactive iodine was well observed in bilateral lung fields. Conclusion Reconstruction using titanium micromesh covered with Marlex mesh is possible for repairing the wide chest wall resection required for thyroid carcinoma metastasis. This technique would help to enhance treatment efficacy in the combination therapy of radioactive iodine and surgery in patients with large thyroid carcinoma metastasis in the chest wall.

    2012-01-01

    Full Text Available Background and objective Massive hemoptysis was a rare but severe postoperative complication of lung cancer. The aim of the present study is to investigate the mechanisms, risk factors, early symptoms, prevention, and treatment options for fatal hemoptysis. Methods From April 2007 to May 2011, 1,737 patients with lung cancer were surgically treated in the West China Hospital of Sichuan University. Twenty patients died during the perioperative period, seven of whom died of massive hemoptysis. These seven cases were analyzed, and their clinical data, as well as related literatures, were reviewed. Results Massive hemoptysis is the second cause of death after lung cancer surgery. Six patients died directly of massive hemoptysis. One patient underwent secondary surgery because of massive hemoptysis, but eventually died because of lung infection and respiratory failure. Early symptoms of hemorrhage were observed in four cases, and the overall incidence rate of massive hemoptysis was 0.4% (7/1,737. Conclusion Bronchovascular fistula (BVF caused by bronchopleural fistula (BPF is the mechanism for massive hemoptysis. Diabetes is a high risk factor. Early diagnosis and surgical treatment of BPF or BVF can prevent the occurrence of death as a result of massive hemoptysis.

  16. Impact of Postoperative Radiation Therapy on Survival in Patients With Complete Resection and Stage I, II, or IIIA Non-Small-Cell Lung Cancer Treated With Adjuvant Chemotherapy: The Adjuvant Navelbine International Trialist Association (ANITA) Randomized Trial

    International Nuclear Information System (INIS)

    Purpose: To study the impact of postoperative radiation therapy (PORT) on survival in the Adjuvant Navelbine International Trialist Association (ANITA) randomized study of adjuvant chemotherapy. Methods and Materials: ANITA is a randomized trial of adjuvant cisplatin and vinorelbine chemotherapy vs. observation in completely resected non-small-cell lung carcinoma (NSCLC) Stages IB to IIIA. Use of PORT was recommended for pN+ disease but was not randomized or mandatory. Each center decided whether to use PORT before initiation of the study. We describe here the survival of patients with and without PORT within each treatment group of ANITA. No statistical comparison of survival was performed because this was an unplanned subgroup analysis. Results: Overall, 232 of 840 patients received PORT (33.3% in the observation arm and 21.6% in the chemotherapy arm). In univariate analysis, PORT had a deleterious effect on the overall population survival. Patients with pN1 disease had an improved survival from PORT in the observation arm (median survival [MS] 25.9 vs. 50.2 months), whereas PORT had a detrimental effect in the chemotherapy group (MS 93.6 months and 46.6 months). In contrast, survival was improved in patients with pN2 disease who received PORT, both in the chemotherapy (MS 23.8 vs. 47.4 months) and observation arm (median 12.7 vs. 22.7 months). Conclusion: This retrospective evaluation suggests a positive effect of PORT in pN2 disease and a negative effect on pN1 disease when patients received adjuvant chemotherapy. The results support further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC

    Background:A positive association between the ABO blood types and survival has been suggested in several malig‑nancies. The aim of this study was to assess the role of the ABO blood types in predicting the prognosis of Chinese patients with curatively resected non‑small cell lung cancer (NSCLC). Methods:We retrospectively analyzed 1601 consecutive Chinese patients who underwent curative surgery for NSCLC between January 1, 2005 and December 31, 2009. The relationship between the ABO blood types and survival was investigated. In addition, univariate and multivariate analyses were performed. Results:Group 1 (patients with the blood type O or B) had signiifcantly prolonged overall survival (OS) compared with group 2 (patients with the blood type A or AB), with a median OS of 74.9months versus 61.5months [hazard ratio (HR) 0.83; 95% conifdence interval (CI) 0.72–0.96;P=0.015]. Additionally, group 1 had signiifcantly longer dis‑ease‑free survival (DFS; HR 0.86; 95% CI 0.76–0.98;P=0.022) and locoregional relapse‑free survival (LRFS; HR 0.79; 95%CI 0.64–0.98;P=0.024) than group 2. The association was not signiifcantly modiifed by other risk factors for NSCLC, including smoking status, pathologic tumor‑node‑metastasis stage, pT category, pN category, and chemotherapy. Conclusions:There is an association between the ABO blood types and the survival of Chinese patients with resected NSCLC. Patients with the blood type O or B had signiifcantly prolonged OS, DFS, and LRFS compared with those with the blood type A or AB.

  19. Risk factors for locoregional recurrence in patients with resected N1 non-small cell lung cancer: a retrospective study to identify patterns of failure and implications for adjuvant radiotherapy

    International Nuclear Information System (INIS)

    Meta-analysis of randomized trials has shown that postoperative radiotherapy (PORT) had a detrimental effect on overall survival (OS) in patients with resected N1 non–small cell lung cancer (NSCLC). Conversely, the locoregional recurrence (LR) rate is reported to be high without adjuvant PORT in these patients. We have evaluated the pattern of failure, actuarial risk and risk factors for LR in order to identify the subset of N1 NSCLC patients with the highest risk of LR. These patients could potentially benefit from PORT. We conducted a retrospective study on 199 patients with pathologically confirmed T1–3N1M0 NSCLC who underwent surgery. None of the patients had positive surgical margins or received preoperative therapy or PORT. The median follow-up was 53.8 months. Complete mediastinal lymph node (MLN) dissection and examination was defined as ≥3 dissected and examined MLN stations; incomplete MLN dissection or examination (IMD) was defined as <3 dissected or examined MLN stations. The primary end point of this study was freedom from LR (FFLR). Differences between patient groups were compared and risk factors for LR were identified by univariate and multivariate analyses. LR was identified in 41 (20.6%) patients, distant metastasis (DM) was identified in 79 (39.7%) patients and concurrent LR and DM was identified in 25 (12.6%) patients. The 3- and 5-year OS rates in patients with resected N1 NSCLC were 78.4% and 65.6%, respectively. The corresponding FFLR rates were 80.8% and 77.3%, respectively. Univariate analyses identified that nonsmokers, ≤23 dissected lymph nodes, visceral pleural invasion and lymph node ratio >10% were significantly associated with lower FFLR rates (P < 0.05). Multivariate analyses further confirmed positive lymph nodes at station 10 and IMD as risk factors for LR (P < 0.05). The 5-year LR rate was highest in patients with both these risk factors (48%). The incidence of LR in patients with surgically resected T1–3N1M0 NSCLC is

    BACKGROUND: Inferior vena cava (IVC) filter insertion is a commonly performed procedure for indications such as recurrent pulmonary emboli or contraindication to anticoagulation. Symptomatic duplication of the IVC is exceedingly rare with only a handful of cases being described in the literature. AIM: We report an unusual case of a patient with symptomatic duplication of the IVC. RESULT: A 53-year-old woman presented at our hospital for resection of a cerebral metastasis from a non-small cell lung cancer following a recent diagnosis of bilateral lower limb deep venous thrombosis. This required perioperative reversal of anticoagulation and IVC filter insertion. Conventional venography performed during filter insertion documented the existence of a duplicated IVC. CONCLUSION: We present a case of a symptomatic duplication of the IVC requiring filter insertion. We review the developmental anatomy of the IVC along with the diagnostic findings and management strategies available.

  5. A retrospective analysis of the effect of intraoperative opioid dose on cancer recurrence after non-small cell lung cancer resection

    International Nuclear Information System (INIS)

    Preclinical studies have demonstrated that opioid receptor agonists increase the rate of non-small cell lung cancer (NSCLC) growth and metastasis. Following institutional review board approval, we retrieved data on 901 patients who underwent surgery for NSCLC at MD Anderson Cancer Center. Comprehensive demographics, intraoperative data, and recurrence-free survival (RFS) and overall survival (OS) at 3 and 5 years were obtained. Cox proportional analyses were conducted to assess the association between intraoperative opioid exposure and RFS and OS. The median intraoperative fentanyl equivalents dosage was 10.15 μg/kg. The multivariate analysis by stage indicated that a trend toward significance for opioid consumption as a risk factor in stage I patients (P = 0.053). No effect was found on RFS for stage II or III patients. Alternatively, opioid consumption was a risk factor for OS for stage I patients (P = 0.036), whereas no effect was noted for stage II or III patients. Intraoperative opioid use is associated with decreased OS in stage I but not stage II–III NSCLC patients. Until randomized controlled studies explore this association further, opioids should continue to be a key component of balanced anesthesia

    At present no simple statement can be made relative to the role of radionuclidic lung studies in the pediatric population. It is safe to assume that they will be used with increasing frequency for research and clinical applications because of their sensitivity and ready applicability to the pediatric patient. Methods comparable to those used in adults can be used in children older than 4 years. In younger children, however, a single injection of 133Xe in solution provides an index of both regional perfusion and ventilation which is easier to accomplish. This method is particularly valuable in infants and neonates because it is rapid, requires no patient cooperation, results in a very low radiation dose, and can be repeated in serial studies. Radionuclidic studies of ventilation and perfusion can be performed in almost all children if the pediatrician and the nuclear medicine specialist have motivation and ingenuity. S

    Background and objective The treatment for early-stage non-small cell lung cancer is primarily surgical. However, the optimal extent of mediastinal lymph node resection remains to be determined. The aim of the current study is to investigate the effect of a pulmonary wedge resection on aged patients with lung cancer. Methods A total of 15 lung cancer patients aged over 70 years were treated via video-assisted thoracoscopic surgery (VATS) wedge resection and mediastinal lymph node sampling from June 2004 to February 2008. Mediastinal lymph node sampling included stations 2R, 4R, 8 and 9 for the right-sided cancers and stations 5, 6,8 and 9 for the left-sided cancers. Results VATS wedge resection and mediastinal lymph node sampling for aged patients with peripheral lung cancer are minimally invasive treatments with a short operative time and low postoperative morbidity. The 1-year and 3-year survival rates were 100% and 86.6%, respectively.

  11. Prognostic model for long-term survival of locally advanced non-small-cell lung cancer patients after neoadjuvant radiochemotherapy and resection integrating clinical and histopathologic factors

    International Nuclear Information System (INIS)

    Outcome of consecutive patients with locally advanced non-small cell lung cancer and histopathologically proven mediastional lymph node metastases treated with induction chemotherapy, neoadjuvant radiochemotherapy and thoracotomy at the West German Cancer Center between 08/2000 and 06/2012 was analysed. A clinico-pathological prognostic model for survival was built including partial or complete response according to computed tomography imaging (CT) as clinical parameters as well as pathologic complete remission (pCR) and mediastinal nodal clearance (MNC) as histopathologic factors. Proportional hazard analysis (PHA) and recursive partitioning analysis (RPA) were used to identify prognostic factors for survival. Long-term survival was defined as survival ≥ 36 months. A total of 157 patients were treated, median follow-up was 97 months. Among these patients, pCR and MNC were observed in 41 and 85 patients, respectively. Overall survival was 56 ± 4% and 36 ± 4% at 24 and 60 months, respectively. Sensitivities of pCR and MNC to detect long-term survivors were 38% and 61%, specificities were 84% and 52%, respectively. Multivariable survival analysis revealed pCR, cN3 category, and gender, as prognostic factors at a level of α < 0.05. Considering only preoperative available parameters, CT response became significant. Classifying patients with a predicted hazard above the median as high risk group and the remaining as low risk patients yielded better separation of the survival curves by the inclusion of histopathologic factors than by preoperative factors alone (p < 0.0001, log rank test). Using RPA, pCR was identified as the top prognostic factor above clinical factors (p = 0.0006). No long term survivors were observed in patients with cT3-4 cN3 tumors without pCR. pCR is the dominant histopathologic response parameter and improves prognostic classifiers, based on clinical parameters. The validated prognostic model can be used to estimate individual prognosis and

    Over the past 30 years, there has been considerable controversy regarding the role of segmental and wedge resections in the management of stage I (T1-T2N0M0) non-small-cell lung cancer. Recently, a prospective randomized trial (Lung Cancer Study Group, 1995) revealed unfavorable results after limited resection, which, in early stage lung cancer, remains a reasonable option for patients with compromised pulmonary reserve, especially those in whom a previous contralateral resection has been performed. The following report describes the role of limited resection in the management of patients with T1-T2N0 non-small-cell lung cancer and presents a retrospective review of our series of 125 limited resections out of 1356 resections performed for lung cancer. In particular, long term survival and the frequency of local/regional recurrence were noted in 92 cases operated on with a curative intent. 26.6% vs 12.5% local/regional recurrence rates were observed among patients undergoing limited resections for T2 and T1 lung cancer, respectively. The five year survival in the limited resection group was 13.5% for T1 and 60% for T2 vs 51% and 72% in the standard procedure group, respectively. The lobectomy results were superior to those of sublobar resection. The latter should be reserved for patients in poor general condition contraindicating a standard lobectomy. PMID:10932366

    Full Text Available Abstract Introduction Video-assisted thoracic surgery (VATS has become routine and widely accepted for the removal of solitary pulmonary nodules of unknown etiology. Thoracosopic techniques continue to evolve with better instruments, robotic applications, and increased patient acceptance and awareness. Several techniques have been described to localize peripheral pulmonary nodules, including pre-operative CT-guided tattooing with methylene blue, CT scan guided spiral/hook wire placement, and transthoracic ultrasound. As pulmonary surgeons well know, the lung and visceral pleura may appear featureless on top of a pulmonary nodule. Case description This paper presents a rapid, direct and inexpensive approach to peripheral lung lesion resection by marking the lung parenchyma on top of the nodule using direct methylene blue injection. Methods In two patients with peripherally located lung nodules (n = 3 scheduled for VATS, we used direct methylene blue injection for intraoperative localization of the pulmonary nodule. Our technique was the following: After finger palpation of the lung, a spinal 25 gauge needle was inserted through an existing port and 0.1 ml of methylene blue was used to tattoo the pleura perpendicular to the localized nodule. The methylene blue tattoo immediately marks the lung surface over the nodule. The surgeon avoids repeated finger palpation, while lining up stapler, graspers and camera, because of the visible tattoo. Our technique eliminates regrasping and repalpating the lung once again to identify a non marked lesion. Results Three lung nodules were resected in two patients. Once each lesion was palpated it was marked, and the area was resected with security of accurate localization. All lung nodules were resected in totality with normal lung parenchymal margins. Our technique added about one minute to the operative time. The two patients were discharged home on the second postoperative day, with no morbidity. Conclusion

    nutritional assessment methods. Objective: To study the rate of hyponutrition in patients candidates to lung resection in southern Galicia, and to determine if there were significant differences in the use of 2 different nutritional assessment methods. Patients and methods: 200 patients participated in this study: 144 males (aged 29-83 years and 56 females (aged 20-80 years. All of them were assessed for their nutritional status according to Chang's method and we also performed a patient-generated global subjective assessment (PG-GSA according to the SENBA working group protocol. Results: There is agreement between the 2 methods in assessing 122 patients as having "good nutritional status". There are two cases with agreement between both methods in the diagnosis of "moderate hyponutrition or risk for hyponutrition". No case of "severe hyponutrition" is diagnosed by the Chang's method. Conclusions: We found statistically significant differences between the observations obtained with the two methods. The Chang's method performed more accurately than the PG-GSA, so that we believe it should be the first choice method for the preoperative nutritional assessment of patients candidate to a lung resection.

    Background It is a surgical dilemma when patients present with both severe heart disease and neoplasms. The best surgical treatment remains controversial. This study aimed to analyze the early and long-term results of simultaneous surgical treatment of severe heart disease and neoplasms.Methods We reviewed the clinical records of 15 patients who underwent simultaneous neoplastic resection and cardiac surgery between September 2006 and January 2011. There were 5 male and 10 female patients. The mean age was (59.2±12.5) years and the mean left ventricular ejection fraction was (57.4±11.0)%. All patients were followed up completely for a period of 12 to 51 months (mean, (33.1±11.2) months).Results Fifteen patients underwent simultaneous cardiac surgery and neoplastic resection. Cardiac procedures consisted of off pump coronary artery bypass grafting (n=7), aortic valve replacement (n=3), mitral valve replacement (n=3), mitral valve replacement with coronary artery bypass grafting (n=1) and left atrial myxoma resection (n=1). Neoplastic resection consisted of lung cancer resection (n=5). colonic cancer resection (n=3), gallbladder resection (n=1), colonic cancer resection with gallbladder resection (n=1), hysterectomy (n=2), hysterectomy with bilateral salpingo-oophorectomy (n=2) and left ovariectomy (n=1). Pathological examination confirmed malignant disease in 10 patients and benign disease in 5 patients. There were no perioperative myocardial infarctions, stroke, pericardial tamponade, renal failure or hospital deaths. The most frequent complications were atrial fibrillation (33.3%), pneumonia (26.7%), low cardiac output syndrome (6.7%) and delayed healing of surgical wounds (6.7%). There was 1 late death 42 months after surgery for recurrent malignant disease. At 1 and 3 years, survival rates were 100% (Kaplan-Meier method).Conclusions Simultaneous cardiac surgery and neoplastic resection was not associated with increased early or late morbidity or mortality

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

  18. Unusual Bilateral Rim Fracture in Femoroacetabular Impingement

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

    BACKGROUND Olfactory neuroblastoma (ONB), also known as esthesioneuroblastoma, is a rare malignant head and neck cancer thought to originate from the olfactory epithelium. It typically invades contiguous structures at presentation. We report a very rare case of multifocal and ectopic ONB. CASE REPORT A 41-year-old man presented with left nasal obstruction and occasional left epistaxis associated with headache. Endoscopic examination of the nasal cavities and computed tomography suggested bilateral polypoid masses. Histopathological diagnosis after endoscopic resection established bilateral olfactory neuroblastoma of the ethmoid sinuses. The patient received postoperative radiotherapy. He remains free of disease 4 years after treatment. CONCLUSIONS To the best of our knowledge this is the second documented case of multifocal ectopic olfactory neuroblastoma. Clinicians should consider ONB in the differential diagnosis of bilateral synchronous nasal and paranasal masses to avoid delayed diagnosis. Endoscopic resection of ONB could be an option in selected cases. PMID:27097989

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

  6. Outcome after Radiofrequency Ablation of Sarcoma Lung Metastases

    International Nuclear Information System (INIS)

    PurposeResection is the mainstay of management in patients with sarcoma lung metastases, but there is a limit to how many resections can be performed. Some patients with inoperable disease have small-volume lung metastases that are amenable to thermal ablation. We report our results after radiofrequency ablation (RFA).MethodsThis is a retrospective study of patients treated from 2007 to 2012 in whom the intention was to treat all sites of disease and who had a minimum CT follow-up of 4 months. Treatment was performed under general anesthesia/conscious sedation using cool-tip RFA. Follow-up CT scans were analyzed for local control. Primary tumor type, location, grade, disease-free interval, prior resection/chemotherapy, number and size of lung tumors, uni- or bilateral disease, complications, and overall and progression-free survival were recorded.ResultsTwenty-two patients [15 women; median age 48 (range 10–78) years] with 55 lung metastases were treated in 30 sessions. Mean and median tumor size and initial number were 0.9 cm and 0.7 (range 0.5–2) cm, and 2.5 and 1 (1–7) respectively. Median CT and clinical follow-up were 12 (4–54) and 20 (8–63) months, respectively. Primary local control rate was 52 of 55 (95 %). There were 2 of 30 (6.6 %) Common Terminology Criteria grade 3 complications with no long-term sequelae. Mean (median not reached) and 2- and 3-year overall survival were 51 months, and 94 and 85 %. Median and 1- and 2-year progression-free survival were 12 months, and 53 and 23 %. Prior disease-free interval was the only significant factor to affect overall survival.ConclusionRFA is a safe and effective treatment for patients with small-volume sarcoma metastases

  7. Lung cancer

    International Nuclear Information System (INIS)

    There will be over 160,000 cases of lung cancer diagnosed in the US in 1991, and deaths from this disease account for a quarter of all cancer deaths in this country. The incidence of lung cancer has continued to increase, especially among women. With 31% of American men and 25% of American women identified in the 1985 census as cigarette smokers, it is likely that this trend will continue well into the next century. Unfortunately, the majority of patients present with locally advanced tumors or distant metastatic disease. Presently, most patients with lung cancer will receive radiation therapy either in an attempt to control inoperable or locally advanced disease, or for palliation of symptomatic intrathoracic or metastatic disease. Because of the poor prognosis of all patients excepting those with early stage resectable lesions, lung cancer is appropriately the subject of intense clinical investigation and controversy throughout the world

  9. Phase III study comparing chemotherapy and radiotherapy with preoperative chemotherapy and surgical resection in patients with non-small-cell lung cancer with spread to mediastinal lymph nodes (N2); final report of RTOG 89-01

    International Nuclear Information System (INIS)

    Purpose: To compare the outcome of treatment of mediastinoscopy-verified N2 non-small-cell lung cancer treated with induction chemotherapy followed by either surgery or radiotherapy (RT), with both options followed by consolidation chemotherapy. Methods and Materials: A randomized Phase III trial for Stage IIIA (T1-T3N2M0) non-small cell lung cancer was conducted by the Radiation Therapy Oncology Group (RTOG) and Eastern Cooperative Oncology Group between April 1990 and April 1994. After documentation of N2 disease by mediastinoscopy or anterior mediastinotomy, patients received induction chemotherapy with cisplatin, vinblastine, and mitomycin-C. Mitomycin-C was later dropped from the induction regimen. Patients were then randomized to surgery or RT (64 Gy in 7 weeks) followed by cisplatin and vinblastine. Results: RTOG 89-01 accrued 75 patients, of whom 73 were eligible and analyzable. Twelve patients received induction chemotherapy but were not randomized to RT or surgery thereafter. Forty-five patients were randomized to postinduction RT or surgery. Of the analyzable patients, 90% had a Karnofsky performance score of 90-100, 18% had weight loss >5%, 37% had squamous cell histologic features, and 54% had bulky N2 disease. The distribution of bulky N2 disease was uniform among the treatment arms. The incidence of Grade 4 toxicity was 56% in patients receiving mitomycin-C and 29% in those who did not. Only 1 patient in each group had acute nonhematologic toxicity greater than Grade 3 (nausea and vomiting). No acute Grade 4 radiation toxicity developed. The incidences of long-term toxicity were equivalent across the arms. Three treatment-related deaths occurred: 2 patients in the surgical arms (one late pulmonary toxicity and one pulmonary embolus), and 1 patient in the radiation arm (radiation pneumonitis). Induction chemotherapy was completed in 78% of the patients. Complete resection was performed in 73% of 26 patients undergoing thoracotomy. Consolidation

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    2013-06-15

    Purpose. To analyze the factors associated with favorable survival in patients with inoperable colorectal lung metastases treated with percutaneous image-guided radiofrequency ablation. Methods. Between 2002 and 2011, a total of 398 metastases were ablated in 122 patients (87 male, median age 68 years, range 29-90 years) at 256 procedures. Percutaneous CT-guided cool-tip radiofrequency ablation was performed under sedation/general anesthesia. Maximum tumor size, number of tumors ablated, number of procedures, concurrent/prior liver ablation, previous liver or lung resection, systemic chemotherapy, disease-free interval from primary resection to lung metastasis, and survival from first ablation were recorded prospectively. Kaplan-Meier analysis was performed, and factors were compared by log rank test. Results. The initial number of metastases ablated was 2.3 (range 1-8); the total number was 3.3 (range 1-15). The maximum tumor diameter was 1.7 (range 0.5-4) cm, and the number of procedures was 2 (range 1-10). The major complication rate was 3.9 %. Overall median and 3-year survival rate were 41 months and 57 %. Survival was better in patients with smaller tumors-a median of 51 months, with 3-year survival of 64 % for tumors 2 cm or smaller versus 31 months and 44 % for tumors 2.1-4 cm (p = 0.08). The number of metastases ablated and whether the tumors were unilateral or bilateral did not affect survival. The presence of treated liver metastases, systemic chemotherapy, or prior lung resection did not affect survival. Conclusion. Three-year survival of 57 % in patients with inoperable colorectal lung metastases is better than would be expected with chemotherapy alone. Patients with inoperable but small-volume colorectal lung metastases should be referred for ablation.

    Intra-articular ganglion cysts of the anterior cruciate ligament (ACL) are rare, and bilateral ganglion cysts are even rarer. These cysts may cause intermittent or chronic nonspecific knee discomfort. Although three cases of bilateral ganglion cysts have been reported in the literature, the knees were not simultaneously affected in those cases. Herein, we report the case of a 56-year-old woman who presented with simultaneous bilateral ganglion cysts of the ACL that were symptomatic. She was successfully treated with arthroscopic resection and debridement. We also present a brief review of the literature, highlighting the aetiology, diagnosis and management of ganglion cysts of the ACL. To the best of our knowledge, this is the first report of simultaneous bilateral intra-articular ganglion cysts of the ACL. PMID:25917477

    The authors report three sisters with bilateral isolated apical pleural fibrosis of unknown origin, which did not respond to empirical antituberculosis therapy and oral corticosteroids. The disease evolved in an unrelenting fashion producing pleural fibrosis at the lung bases and leading to the death of two sisters and to lung transplantation in the other one. There was no history of other familial disease or consanguinity. The particular features of these cases and the differences from other reports of apparently cryptogenic pleural fibrosis are outlined.

    Tracheobronchial disruption is uncommon in blunt chest trauma. Many of these patients die before reaching the hospital. In the majority of survivors diagnosis is occasionally delayed resulting in complications like airway stenosis and lung collapse. Thus it is important to have radiological follow up after severe thoracic trauma. Sleeve resection can be an excellent option to conserve lung tissue in delayed presentation of bronchial transection.

    Organising pneumonia is a histopathological entity characterised by intra-alveolar buds of granulation tissue, intermixed myofibroblasts and connective tissue. Cryptogenic organising pneumonia (COP) is characterised by this particular histopathological pattern, along with typical clinical and imaging features, when no other underlying aetiology is found. COP (previously known as bronchiolitis obliterans organising pneumonia [BOOP]) is one of the rare variants of interstitial pneumonias. This condition is characterised by a rapid clinical and radiological improvement with steroid treatment. Here we are reporting a case of COP in adult female with discussion on approach and basic pathophysiology of this type of pneumonia. PMID:26731829

    2014-07-01

    Residual tumor resection (RTR) in patients with metastatic testicular cancer plays a pivotal role in a multimodal treatment. It can be performed unilaterally or as an extended bilateral RTR. Additional surgical procedures might be necessary, such as nephrectomy, splenectomy, partial colectomy, or vascular interventions with possible caval resection, cavotomy, or aortic resection with aortic grafting. Consequently, several complications can be seen in the intra- and postoperative course, most common of which are superficial wound infections, intestinal paralysis, lymphocele, and chylous ascites. We sought to describe complication management and how to prevent complications before they arise. PMID:25023235

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge. PMID:9503974

    A clinical feature of bilateral popliteal arterial dissection without involving the descending aorta, bilateral iliac, as well as femoral arteries has never been reported in the past literature. We report a 56-year-old man with hypertension and coronary artery disease who presented to our emergency department with complaints of bilateral knee pain after long-distance walking. Physical examination was notable for elevated blood pressure, but there was no palpable pulsation over dorsalis pedis arteries on his feet. Laboratory evaluation revealed a d-dimer level of 35.2 mg/L (FEU) on the day of the test and 1.2 mg/L one and a half months ago (normal level, <0.55). These findings were suggestive of a recent-onset peripheral arterial occlusive disorder. Computed tomography of the aorta showed bilateral popliteal arterial dissection with arterial intimal flap. Abdominal aorta, bilateral iliac, and femoral arteries remained intact with only arteriosclerotic change. Minimally invasive endovascular stent grafting was then performed. The patient had an uneventful recovery. PMID:21106320

    Full Text Available Morgagni hernia is a rare congenital diaphragmatic hernia. It is seen rarely bilaterally. Patients are usually asymptomatic. Therefore, diagnosis may be delayed until adulthood. Significant morbidity can occur in case complications arise and diagnosis is delayed. The patient, a 74 year-old female, presented in this article, was admitted to the emergency department with abdominal pain, vomiting, and shortness of breath. The plain abdominal radiograph of the patient revealed bowel obstruction and suspicious appearence in favor of the diaphragmatic hernia on both sides of the sternum. Computed tomography revealed bilaterally incarcerated Morgagni hernia with strangulated omentum in the right side of the sternum and a part of colon in the left side of sternum. Incarcerated organs were withdrawn to peritoneal cavity and defects of hernia were sutured primarily on laparatomy. Because bilateral incarcerated Morgagni hernia can be seen rarely, this case was reported.

    Unilateral pallidotomy is a safe and effective treatment for medically refractory bradykinetic Parkinson's disease, especially in those patients with levodopa-induced dyskinesia and severe on-off fluctuations. The efficacy of bilateral pallidotomy is less certain. The authors completed 11 of 12 attempted bilateral pallidotomies among 150 patients undergoing pallidotomy at New York University. In all but one patient, the pallidotomies were separated by at least 9 months. Patients were selected for bilateral pallidotomy if they exhibited bilateral rigidity, bradykinesia, or levodopa-induced dyskinesia prior to treatment or if they exhibited disease progression contralateral to their previously treated side. The Unified Parkinson's Disease Rating Scale (UPDRS) and timed upper-extremity tasks of the Core Assessment Protocol for Intracerebral Transplantation (CAPIT) were administered to all 12 patients in the "off" state (12 hours without receiving medications) preoperatively and again at 6 and 12 months after each procedure. The median UPDRS and contralateral CAPIT scores improved 60% following the initial procedure (p = 0.008, Wilcoxon rank sums test). The second pallidotomy generated only an additional 10% improvement in the UPDRS and CAPIT scores ipsilateral to the original procedure (p = 0.05). Worsened speech was observed in two cases. In the 12th case, total speech arrest was noted during test stimulation. Speech returned within minutes after stimulation was halted. Lesioning was not performed. These results indicate that bilateral pallidotomy has a narrow therapeutic window. Motor improvement ipsilateral to the first lesion leaves little room for further improvement from the second lesion and the risk of speech deficit is greatly enhanced. Chronic pallidal stimulation contralateral to a previously successful pallidotomy may prove to be a safer alternative for the subset of patients who require bilateral procedures. PMID:15096015

    Full Text Available We report a case of adrenal metastasis from colorectal cancer in a 54-year-old woman. Nine months after resection for advanced rectal carcinoma, a computed tomography scan revealed bilateral adrenal metastasis. The level of serum carcinoembryonic antigen was normal. A bilateral adrenalectomy was performed after chemotherapy. Histopathological examination showed adenocarcinoma, compatible with metastasis from the rectal cancer. Adrenal metastasis should be considered in the patients’ follow-up for colorectal cancer.

    Full Text Available Purpose: To report a case of bilateral primary intraocular lymphoma. Case report: A 33-year-old man presented with bilateral blurred vision since two years ago. Examination revealed large keratic precipitates, anterior chamber reaction, posterior subcapsular cataracts, and vitreous infiltration. After a short trial of topical and periocular steroids, diagnostic 25-gauge pars plana vitrectomy was performed and cytologic evaluation of the aspirate confirmed a diagnosis of intraocular lymphoma. The patient was subsequently managed with intravitreal methotrexate in both eyes and responded favorably. Central nervous system workup for lymphoma was negative. Conclusion: Primary intraocular lymphoma should be considered in young adults suffering from chronic recalcitrant panuveitis.

    Paragangliomas of the head and neck are rare neoplasms presented as cervical mass, generally bilateral, that arise from chemoreceptors located at the carotid bifurcation (carotid body tumors), along the vagus nerve (vagal paragangliomas), and in the jugular fossa and tympanic cavity (jugulotympanic paragangliomas). They are typically asymptomatic at the beginning, highly vascular, slow-growing and compressing the surrounding anatomic structures. Only radical surgery is the curative treatment for paragangliomas. We present a case of a 62- year-old woman with a diagnosis of bilateral neck paragangliomas where surgical removal was judged burdened by excessive risk because of the size of the tumor.

Six months after systemic chemotherapy was initiated, all tumours had disappeared with the exception of the liver tumour and a tiny lung tumour 2.5 mm in diameter. Fluoroscopy-assisted thoracoscopic resection of the pulmonary nodule was performed to evaluate whether viable tumour tissue remained in the lung lesion. Before moving the patient to the operating room, the nodule was marked by Lipiodol under CT fluoroscopic guidance with the patient under local anaesthesia. This procedure allowed correct visualisation of the area that should be resected.

  7. Scintigraphy of incidentally discovered bilateral adrenal masses

    International Nuclear Information System (INIS)

    The purpose of this study was to determine the patterns of iodine-131 6β-iodomethylnorcholesterol (NP-59) imaging and the correlation with CT-guided adrenal biopsy and follow-up in patients with bilateral adrenal masses. To this end we investigated a consecutive sample of 29 euadrenal patients with bilateral adrenal masses discovered on CT for reasons other than suspected adrenal disease. Adrenal scintigraphy was performed using 1 mCi of NP-59 injected i.v., with gamma camera imaging 5-7 d later. In 13 of the 29 patients bilateral adrenal masses were the result of metastatic involvement from lung carcinoma (5), lymphoma (3), adrenocarcinoma of the colon (3), squamous cell carcinoma of the larynx (1), and anaplastic carcinoma of unknown primary (1). Among these cases the NP-59 scan demonstrated either bilaterally absent tracer accumulation (8, all with bilateral metastases) or marked asymmetry of adrenocortical NP-59 uptake (5). Biopsy of the adrenal demonstrating the least NP-59 uptake documented malignant involvement of that gland in five of five patients. In two patients an adenoma was found simultaneously in one adrenal with a contralateral malignant adrenal mass. In each of these cases, the adenoma demonstrated the greatest NP-59 uptake. In 16 patients diagnosis of adenoma was made on the basis of CT-guided adrenal biopsy of the gland with the greatest NP-59 uptake of the pair (n=4), or adrenalectomy (n=2), or absence of change in the size of the adrenal mass on follow-up CT scanning performed 6 months to 3 years later (n=10).

    Benign metastasizing leiomyoma (BML) usually are situated in one organ, most often in lungs. BML patients typically have a history of uterine leiomyoma treated with hysterectomy, myomectomy or subtotal hysterectomy. The aim of the study was to present the case of a 53-year-old woman with triple location in the lungs, parametria and appendix. She had undergone a myomectomy 26 years earlier. In 2015, she was admitted to the surgical department because of abdominal pain, whereupon a cholecystectomy was performed. CT scans showed pelvic mass with pulmonary metastasis. Upon discharge the patient was referred to the Gynecology Clinic, where a laparotomy was performed. The intraoperative findings were: 1) uterus with multiple leiomyomas, 2) four tumors in the parametria, 3) tumor connected to the appendix. A subtotal hysterectomy, with a bilateral salpingo-oophorectomy, removal of the tumors from the parametria and appendectomy was performed. Pathology confirmed the diagnosis based on morphology and immunohistochemical staining (strongly positive for estrogen receptors and SMA, while Ki67 was very low, below 1%). Upon postoperative recovery, the patient was referred to the Thoracic Surgery Department. During the thoracotomy, multiple nodes, surrounded by lung parenchyma, were revealed. Wedge resection was performed, for localized pulmonary lesions, and sent for pathological examination. The final pathological diagnosis was benign metastasizing leiomyomatosis. In conclusion, the triple location of BML could possibly be a result of a parallel different metastasizing mechanism, although it is impossible to exclude one mechanism, which may be the cause of the metastases in three locations.

  9. CT-guided resection of pulmonary metastases

    International Nuclear Information System (INIS)

    Purpose: to evaluate the feasibility and potential use of intraoperative computed tomography (IOP CT) as guidance for video-assisted thoracic surgery (VATS). Material and methods: fifteen consecutive patients with peripheral intrapulmonary nodules underwent a thoracoscopy with IOP CT. Solitary lesions were known in 6/15 patients (40%, group II) whereas 9/15 (60%, group I) patients had multiple lesions (n ≥ 2). IOP CT was performed with the mobile CT scanner Philips Tomoscan M. Radiologists intraoperatively placed percutaneous marks of lung lesions after unsuccessful VATS by use of a lung marker set (Somatex, Teltow, Germany). VATS was performed under general anaesthesia and with double lumen endotracheal intubation for single lung ventilation. Imaging quality and imaging of pulmonary nodules were rated. Results: IOP CT was evaluated as feasible combined with VATS. Thoracotomy was avoided in 5/15 patients where lesions could not be detected by VATS. A CT-guided biopsy was performed in two patients after an unsuccessful attempt of thoracoscopy. There were no documented side effects. Conclusion: first clinical results suggest that a combination of VATS and IOP CT is feasible. Thus, the number of open thoracoscopies might be decreased. Intrapulmonary lesions not detectable with VATS could be marked under CT - guidance intraoperatively and then resected by thoracoscopy. (orig.)

    The role of perioperative chemotherapy in the management of initially resectable colorectal liver metastases (CRLM) is still unclear. The EPOC trial [the European Organization for Research and Treatment of Cancer (EORTC) 40983] is an important study that declares perioperative chemotherapy as the standard of care for patients with resectable CRLM, and the strategy is widely accepted in western countries. Compared with surgery alone, perioperative FOLFOX therapy significantly increased progression-free survival (PFS) in eligible patients or those with resected CRLM. Overall survival (OS) data from the EPOC trial were recently published in The Lancet Oncology, 2013. Here, we discussed the findings and recommendations from the EORTC 40983 trial. PMID:25713806

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

    Full Text Available This study was designed to investigate cerebellar lobular contributions to specific cognitive deficits observed after cerebellar tumor resection. Verbal working memory (VWM tasks were administered to children following surgical resection of cerebellar pilocytic astrocytomas and age-matched controls. Anatomical MRI scans were used to quantify the extent of cerebellar lobular damage from each patient's resection. Patients exhibited significantly reduced digit span for auditory but not visual stimuli, relative to controls, and damage to left hemispheral lobule VIII was significantly correlated with this deficit. Patients also showed reduced effects of articulatory suppression and this was correlated with damage to the vermis and hemispheral lobule IV/V bilaterally. Phonological similarity and recency effects did not differ overall between patients and controls, but outlier patients with abnormal phonological similarity effects to either auditory or visual stimuli were found to have damage to hemispheral lobule VIII/VIIB on the left and right, respectively. We postulate that damage to left hemispheral lobule VIII may interfere with encoding of auditory stimuli into the phonological store. These data corroborate neuroimaging studies showing focal cerebellar activation during VWM paradigms, and thereby allow us to predict with greater accuracy which specific neurocognitive processes will be affected by a cerebellar tumor resection.

Surgery is not only the main curative treatment modality in patients with early-stage lung cancer but it also has a significant role in the initial workup for the diagnosis and staging of lung cancer. This article describes the surgical management of patients with lung cancer. Surgical resection for lung cancer is still regarded as the most effective method for controlling the primary tumor, provided it is resectable for cure and the risks of the procedure are low. The 5-year survival rare following complete resection (R0 of a lung cancer is stage dependent [Table 1]. [1-3] Incomplete resection (R1, R2 rarely, if ever, cures the patient.

The bilateral pneumothorax critically deteriorated after 4 days from onset and urgent bilateral chest drainages were performed. Nevertheless the drainages the full expansion of both lungs was not obtained and air leakage only from left side was continued. A video-assisted left bullectomy was performed 9 days after the tube insertion. The two bars penetrating anterior mediastinal pleura were thought to be a cause of the simultaneous bilateral spontaneous pneumothorax. PMID:25352312

    @@ 1 Introduction The feasibility of colon resection using the laparoscope was demonstrated as early as 1991[1~3]. It was shown one year later that it is also possible to use the laparoscope in abdominoperineal resection of the rectum for rectal carcinoma[4, 5]. One year after this, the first study was reported in which the results of anterior resection with the laparoscope were compared with the conventional operation in a small number of patients with carcinoma of the rectum[6]. The first reports on the feasibility of total excision of the mesorectum in patients with carcinoma of the middle or lower third of the rectum were first published at the start of this century[7~9]. It can be stated in summary that resection of the colon or rectum using the laparoscope is not of disadvantage to the patient, given that the surgeon has appropriate experience and the patient has been properly selected.

    The quality of radical oncological operations for patients with rectal cancer determines the rate of local recurrence and long-term survival. Neoadjuvant chemoradiotherapy for locally advanced tumors, a standardized surgical procedure for rectal tumors less than 12 cm from the anus with total mesorectal excision (TME) and preservation of the autonomous nerve system for sexual and bladder function have significantly improved the oncological results and quality of life of patients. The TME procedure for rectal resection has been performed laparoscopically in Germany for almost 20 years; however, no reliable data are available on the frequency of laparoscopic procedures in rectal cancer patients in Germany. The rate of minimally invasive procedures is estimated to be less than 20 %. A prerequisite for using the laparoscopic approach is implicit adherence to the described standards of open surgery. Available data from prospective randomized trials, systematic reviews and meta-analyses indicate that in the early postoperative phase the generally well-known positive effects of the minimally invasive approach to the benefit of patients can be realized without any long-term negative impact on the oncological results; however, the results of many of these studies are difficult to interpret because it could not be confirmed whether the hospitals and surgeons involved had successfully completed the learning curve. In this article we would like to present our technique, which we have developed over the past 17 years in more than 1000 patients. Based on our experiences the laparoscopic approach can be highly recommended as a suitable alternative to the open procedure. PMID:27277556

    A case of bilateral sub-condylar fracture with wide stump dislocation associated with a central facial trauma, fracture-intrusion of the rhino-orbital-maxillary complex and a parasymphyseal mandibular fracture, is reported. After surgery and inter-maxillary fixation an unusual temporo-mandibular ankylosis developed. Maximum mouth opening, lateral and protrusive movements were severely limited. Surgical treatment of ankylosis was requested and performed. The originality of this case lies in the atypical lateral dislocation of condylar neck fractured stumps to the zygomatic arches and in the later appearance of ankylosis between the glenoid fossa, zygomatic arch, condylar neck stump, and the condylar process displaced anteromedially. The ankylosed blocks were resected, displaced condyles were also removed due to the strong adhesion with the ankylotic tissue and the lack of any anatomical continuity or connection with the glenoid fossa. Functional therapy allowed the resolution of the functional limitation. PMID:11723434

    Acquired emphysema is a rare pathology in pediatrics. We report the case of a patient born at term with a neonatal respiratory distress, which had required mechanical ventilation. She developed gradually chronic obstructive pulmonary disease with severe emphysematous lesions, respiratory failure and functional impairments. Bilateral emphysema resection, performed at 16 years old, allowed major functional benefits at rest and during exercise. We present the results of respiratory functional evaluations, walk tests and maximal exercise tests (including measure of dynamic hyperinflation) before and after surgery, which highlights that surgery is a successful option in the treatment of compressive emphysema in childhood.

    Full Text Available Pheochromocytoma is a rare catecholamine secreting neuroendocrine tumor in children. It is usually localized unilaterally in adults but often bilaterally in children. The symptoms are variable related to the level of secreted catecholamine. The most common symptoms are hypertension, tachycardia and headache. Beta blockers, alcohol consumption, injection of contrast substance and surgical procedures may lead to attacks. The most effective treatment is surgical resection. In recent years, laparoscopic surgery has been more preferred. Anesthetic management is very important in this cases. Especially, sudden hemodynamic changes may be observed during laparoscopic adrenalectomy. In our case, the control of hemodynamic changes with esmolol and norepinephrine infusion were discussed during bilaterally laparoscopic adrenalectomy in a 14-year old child with pheochromocytoma.

    We report a case in which an immature teratoma developed following three previous resections for mature cystic teratomas. The patient was a 26-year-old nulliparous woman with a regular menstrual cycle. Twelve years earlier, she had consulted a pediatrician for complaints of lower abdominal pain. Bilateral cystic teratomas were suspected and she underwent a left salpingo-oophorectomy and a right cystectomy laparoscopically, and bilateral mature cystic teratomas were diagnosed histologically. She underwent a right cystectomy twice afterwards and mature cystic teratomas were diagnosed. Three years after the third surgery, a regular checkup performed annually for ovarian cyst recurrence revealed a 9.3 cm ovarian cyst by ultrasonography without marker elevation or complaint of symptoms. Magnetic resonance imaging (MRI) showed a 10 cm multilocular cyst, including a part with heterogeneous medium and high-signal intensity on T2-weighted images, which revealed enhancement on dynamic contrast-enhanced MRI unlike the previous images. Ovarian tumors, including immature teratomas and malignancy, were considered. She had a strong wish to undergo laparoscopic surgery. She was diagnosed with an immature teratoma, grade 1 of the right ovary. Although the frequency of recurrence of immature teratomas after resection of mature cystic teratomas is very low, regular checkups are necessary because there may be no associated symptoms.

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    2003-08-01

    Full Text Available Inverted papilloma is an uncommon benign neoplasm originating from lateral nasal wall. It commonly invades paranasal sinuses and sometimes invasion to orbit and intracranial structures are seen. There are many surgical methods for its treatment, one of them is endoscopic transnasal approach."nMaterials and Methods: Between 1997 and 2001, 11 patients with this tumor were operated in Amiralam hospital in Tehran and Shahid Rahnemun in Yazd. Nine patients were operated by endoscopic transnasal route and two patients by combined Caldwell-luc and endoscopic transnasal routes."nResults: Tumors were on the right side in 3 patients, on the left side in 7 patients, and bilateral in one patient. There were no intracranial or orbital extensions. No pathologic report of malignancy was made. Surgical technique included complete tumor resection, anterior and posterior ethomidectomies, sphenoidectomy, frontal recess tumor resection and wide maxillary antrostomy, in cases in whom tumor was attached to lamina papyracea, the lamina was removed without any manipulation to orbital periosteum. Mean follow-up time was 29.8 months. There was no recurrence in 82% of cases. Tumor recurred in 18% of cases. No complications were seen."nConclusion: Although the standard treatment for this tumor is medial maxillectomy but endoscopic resection is an effective method in surgery of this tumor. It seems that if tumor does not extend to areas unreachable by endoscopic surgery, due to lower morbidity and excellent visualization of tumor, this method is preferable.

  4. Parenteral Nutrition in Liver Resection

    Full Text Available Albeit a very large number of experiments have assessed the impact of various substrates on liver regeneration after partial hepatectomy, a limited number of clinical studies have evaluated artificial nutrition in liver resection patients. This is a peculiar topic because many patients do not need artificial nutrition, while several patients need it because of malnutrition and/or prolonged inability to feeding caused by complications. The optimal nutritional regimen to support liver regeneration, within other postoperative problems or complications, is not yet exactly defined. This short review addresses relevant aspects and potential developments in the issue of postoperative parenteral nutrition after liver resection.

    Purpose/Objectives: The aim of this study was to evaluate the impact of definitive thoracic chemoradiation therapy following surgery or stereotactic radiosurgery (SRS) and whole-brain radiation therapy (WBRT) on the outcomes of patients with non-small cell lung cancer (NSCLC) with synchronous solitary brain metastasis (SSBM). Methods and Materials: A total of 63 NSCLC patients with SSBM were retrospectively evaluated. Patients were staged using positron emission tomography-computed tomography in addition to conventional staging tools. Thoracic radiation therapy (TRT) with a total dose of 66 Gy in 2 Gy fractions was delivered along with 2 cycles of cisplatin-based chemotherapy following either surgery plus 30 Gy of WBRT (n=33) or SRS plus 30 Gy of WBRT (n=30) for BM. Results: Overall, the treatment was well tolerated. All patients received planned TRT, and 57 patients (90.5%) were also able to receive 2 cycles of chemotherapy. At a median follow-up of 25.3 months (7.1-52.1 months), the median months of overall, locoregional progression-free, neurological progression-free, and progression-free survival were 28.6, 17.7, 26.4, and 14.6, respectively. Both univariate and multivariate analyses revealed that patients with a T1-T2 thoracic disease burden (P=.001), a nodal stage of N0-N1 (P=.003), and no weight loss (P=.008) exhibited superior survival. Conclusions: In the present series, surgical and radiosurgical treatments directed toward SSBM in NSCLC patients were equally effective. The similarities between the present survival outcomes and those reported in other studies for locally advanced NSCLC patients indicate the potentially curative role of definitive chemoradiation therapy for highly selected patients with SSBM.

    We present a 10-year-old boy having the bronchiectasis who was subjected to lung perfusion scintigraphy before lung resection surgery to assess the lung parenchymal function. It revealed unusual tracer distribution in right upper body that was mimicking to be liver. It was unusual unless there were some shunts bypassing the lung uptake or faulty radiopharmaceutical preparation. However by bringing down the image window, it became clear that radiopharmaceutical distribution was in thorax only correlating with lung uptake, and not in the liver.

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

    It is believed that primary tumor resection modulates host-tumor immune interaction, but this has not been characterized in a stringent breast cancer tumor model. This report, using the 4T1 murine mammary tumor model, characterizes for the first time the dynamic longitudinal changes in immunosuppressive and effector components of the immune system after resection of an established orthotopic primary tumor with a defined natural history of developing lung metastases. More specifically, we analyzed changes of absolute numbers and frequencies of MDSC, regulatory T cells (Treg), as well as activated CD4 and CD8 positive T cells in spleens and, in some studies, lungs of 4T1 tumor-bearing mice and mice after primary tumor resection. Importantly, using mathematical analyses we established that primary resection of an orthotopic tumor had created a "window of opportunity" with decreased tumor-associated immune suppression that existed for approximately 10 days. Although tumor resection did slightly prolong survival, it did not affect the ultimate development of metastatic disease since animals with resected tumors or intact primary tumors eventually died by day 47 and 43, respectively. This window of opportunity likely occurs in humans providing a rationale and parameters for integration and testing of immunotherapeutic strategies in this critical "window of opportunity" to combat the development of metastatic disease.

    BACKGROUND:Pancreatic adenocarcinoma (PCa) is a disease with dismal prognosis, and the only possibility of cure, albeit small, is based on the combination of complete resection with negative histopathological margins (R0 resection) with adjuvant treatment. Therefore, a lot of effort has been made during the last decade to assess the role of extensive surgery in both local recurrence and survival of patients with PCa. DATA SOURCES:Medline search and manual cross-referencing were utilized to identify published evidence-based data for PCa surgery between 1973 and 2006, with emphasis to feasibility, efifcacy, long-term survival, disease free survival, recurrence rates, pain relief and quality of life. RESULTS: Extended surgery is safe and feasible in high volume surgical centers with comparable short-term results. Organ preserving surgery is a main goal because of quality of life reasons and is performed whenever possible from the tumor extent. Concerning long-term survival major vein resection does not adversely affect outcome. To date, there are no changes in long-term survival attributed to the extended lymph node dissection. However, there is a beneift in locoregional control with fewer local recurrences and extended lymphadenectomy allows better staging for the disease. CONCLUSIONS:Extended PCa surgery is safe and feasible despite the inconclusive results in patient's survival beneift. In the future, appropriately powered randomized trials of standard vs. extended resections may show improved outcomes for PCa patients.

    2016-06-01

    Background Lung volume reduction surgery (LVRS) is a well-established treatment option for pulmonary emphysema, but the most advantageous technical approach remains debatable. Methods Short- and long-term outcomes were comparably assessed in pulmonary emphysema patients who underwent unilateral LVRS with either lobe or sublobe (segment or wedge) resection. Patients were consecutively enrolled in the study after careful conventional and computer-based definition of the target region. Results A total of 36 patients with a mean age of 62.1 ± 8.9 years (range, 41-79 years) were recruited. Video-assisted thoracoscopy (VATS) was performed in 33 patients, while 3 patients with additional early-stage lung cancer received anterolateral thoracotomy. Surgery duration was longer for lobectomy (median 93 minutes, range 44-168 minutes) as compared with sublobe resection (median 52 minutes, range 25-131 minutes; p = 0.0007), but complication rates were similar. After 90 days postsurgery, mortality was zero and lung function improved to a similar degree in both the groups. After 1 year, total lung capacity (TLC) was still reduced by 17.2 ± 20.6% predicted as compared with the baseline values for lobe resection, while TLC was increased by 12.1 ± 14.5% predicted for sublobe resection. In addition, the 6-minute walking distance improved following LVRS, with slightly better results in lobe resection patients. Conclusions By careful definition of the target region, unilateral VATS-LVRS with lobe resection in severely affected pulmonary emphysema patients is a safe procedure that is superior to unilateral sublobe VATS resection in terms of improving long-term 1-year lung hyperinflation. Therefore, unilateral VATS lobe resection is a promising treatment approach that should be further evaluated by randomized controlled trials. PMID:25535772

    Full Text Available Abstract Leiomyosarcoma of the inferior vena cava (IVCL is a rare retroperitoneal tumor. We report two cases of level II (middle level, renal veins to hepatic veins IVCL, who underwent en bloc resection with reconstruction of bilateral or left renal venous return using prosthetic grafts. In our cases, IVCL is documented to be occluded preoperatively, therefore, radical resection of tumor and/or right kidney was performed and the distal end of inferior vena cava was resected and without caval reconstruction. None of the patients developed edema or acute renal failure postoperatively. After surgical resection, adjuvant radiation therapy was administrated. The patients have been free of recurrence 2 years and 3 months, 9 months after surgery, respectively, indicating the complete surgical resection and radiotherapy contribute to the better survival. The reconstruction of inferior vena cava was not considered mandatory in level II IVCL, if the retroperitoneal venous collateral pathways have been established. In addition to the curative resection of IVCL, the renal vascular reconstruction minimized the risks of procedure-related acute renal failure, and was more physiologically preferable. This concept was reflected in the treatment of the two patients reported on.

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    Although there have been many advancements in the multidisciplinary management of non-small cell lung cancer (NSCLC), surgery remains the primary modality of choice for resectable lung cancer when the patient is able to tolerate lung resection physiologically. There have been recent advances in surgical diagnosis and treatment of lung cancer. Increasing use of low-dose computed tomography (CT) screening for lung cancer has resulted in increased detection of small peripheral nodules or semi-solid ground glass opacities. Here, we review different modalities of localization techniques that have been used to aid surgical excisional biopsy when needle biopsy has failed to provide tissue diagnosis. We also report on the current debates regarding the use of sublobar resections for Stage I NSCLC as well as the surgical management of locally advanced NSCLC. Finally, we discuss the complex surgical management of T4 NSCLC lung cancers. PMID:26059591

  1. Bilateral support programmes

    International Nuclear Information System (INIS)

    In the Russian Federation, serious consideration is being given to the safety of nuclear facilities and to security of nuclear material. One important factor in ensuring security of nuclear material and facilities is physical protection. The Ministry of Atomic Energy of the Russian Federation is making great efforts to improve physical protection of nuclear facilities. Some of the measures which are being implemented to improve physical protection are being carried out in the framework of international co-operation in this field. To date, the Russian Federation has established bilateral co-operation with the United States of America, Germany, Belgium, France and Finland, and has studied and taken account of the experience of foreign countries in the field of physical protection and nuclear material accounting and control. At present, over 20 enterprises of the Ministry of Atomic Energy of the Russian Federation representing all the main branches of the nuclear activities of the Ministry are involved in international co-operation on physical protection and nuclear material accounting and control. The main branches of this co-operation are as follows: Scientific and technical co-operation; production of a conceptual design to improve physical protection systems directly at nuclear risk facilities; swift improvement of physical protection (without developing design documentation for the nuclear risk facility as a whole); reinforcement of physical protection during the transport of nuclear material; and training of staff at nuclear risk facilities. During this work, many facilities were equipped with modern physical protection and with nuclear material accounting and control equipment. The Ministry of Atomic Energy of the Russian Federation is pleased with the results of this international co-operation and feels that it should continue. (author)

    Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

  6. Patterns and predictors of recurrence after radical resection of thymoma

    International Nuclear Information System (INIS)

    Background: Recurrence of thymomas even after complete resection is common, but the relapse patterns remain controversial. This study aimed to define the patterns and predictors of relapse after complete resection of thymoma. Methods: A single-institution retrospective study was performed with 331 patients who underwent radical resection of thymoma between 1991 and 2012. Results: After a median follow-up of 59 months, the recurrence rate was 6.9% (23/331). Relapse occurred in 23 patients with the pleura (14) and tumor bed (6) as the most common sites of recurrence. According to the definitions of the International Thymic Malignancy Interest Group, 10 (43.5%) patients had local relapse, 15 (65.2%) had regional relapse, 10 (43.5%) had distant relapse. The difference in survival following relapse between lung and regional relapse was statistically significant (P = 0.027) but that between lung and distant relapse was not (P = 0.808). The recurrence rates correlated with the initial Masaoka stage. Further, recurrence also correlated with World Health Organization (WHO) tumor type. The recurrence-free survival rates in patients with tumor size ⩾8 cm were worse than those of patients with tumor size <8 cm (P = 0.007). Tumor size was also correlated with stage (r = 0.110). As tumor becomes larger, the stage is more advanced (P = 0.023). Multivariate analysis showed that Masaoka stage (P = 0.005), tumor size (P = 0.033), and WHO histological type (P = 0.046) were predictive factors of relapse. Conclusion: Regional recurrence is the most common relapse pattern but local and distant relapse are also common. Advanced Masaoka stage, larger tumor size, and type B3 are risk factors of recurrence. Lung relapse should be considered distant relapse. Further, tumor size was correlated with Masaoka stage and therefore should be considered in the staging system

    Purpose: To evaluate mediastinal nodal clearance (MNC) rates after induction chemotherapy and concurrent, full-dose radiation therapy (RT) in a phase II trimodality trial (Radiation Therapy Oncology Group protocol 0229). Patients and Methods: Patients (n=57) with stage III non-small cell lung cancer (pathologically proven N2 or N3) were eligible. Induction chemotherapy consisted of weekly carboplatin (AUC = 2.0) and paclitaxel 50 mg/m{sup 2}. Concurrent RT was prescribed, with 50.4 Gy to the mediastinum and primary tumor and a boost of 10.8 Gy to all gross disease. The mediastinum was pathologically reassessed after completion of chemoradiation. The primary endpoint of the study was MNC, with secondary endpoints of 2-year overall survival and postoperative morbidity/mortality. Results: The grade 3/4 toxicities included hematologic 35%, gastrointestinal 14%, and pulmonary 23%. Forty-three patients (75%) were evaluable for the primary endpoint. Twenty-seven patients achieved the primary endpoint of MNC (63%). Thirty-seven patients underwent resection. There was a 14% incidence of grade 3 postoperative pulmonary complications and 1 30-day, postoperative grade 5 toxicity (3%). With a median follow-up of 24 months for all patients, the 2-year overall survival rate was 54%, and the 2-year progression-free survival rate was 33%. The 2-year overall survival rate was 75% for those who achieved nodal clearance, 52% for those with residual nodal disease, and 23% for those who were not evaluable for the primary endpoint (P=.0002). Conclusions: This multi-institutional trial confirms the ability of neoadjuvant concurrent chemoradiation with full-dose RT to sterilize known mediastinal nodal disease.

  13. Bilateral pheochromocytomas and neuroendocrine tumor of pancreas demonstrated with FDG-PET/CT in a patient with von Hippel-Lindau syndrome: A case report

    International Nuclear Information System (INIS)

    manifestations of VHL are: hemangioblastoma [of retina, CNS (especially cerebellum), kidney, bladder and pancreas], angioma (of retina, liver and spleen), hemangioma (of kidney and bone), lymphatic sac neoplasm of labyrinth, cyst (of lung, kidney, epididymis, pancreas, liver, spleen and bone), hypernephroid tumor of epididymis, renal cell adenoma and carcinoma, testicular germ cell tumor, papillary cystadenoma of broad ligament, pheochromocytoma (adrenal and extra-adrenal), paraganglioma, rhabdomyoma of heart, syringomyelia, meningioma, neuroendocrine tumor of pancreas, nevus and cafe au laic spot of skin, carcinoid of the common bile duct. Although half of VHL pheochromocytomas present bilaterally, these patients requires lifelong biochemical and radiological screening for pheochromocytoma., and there is a high incidence of recurrence after surgery. Tumors at various sites are demonstrable by using different imaging modalities, including US, CT, MRI, and angiography. The preferred examination depends on the site or organ involved. CT and MRI best depict intracranial lesions, and MRI is more appropriate for examining spinal lesions. Retinal tumors are visualized best on US, the kidneys and pancreas can be imaged by using US and/or CT scans. The limitation of various techniques depends on the size of the tumor and on problems with atypia. CT and US findings are not reliable in differentiating cystic renal cell carcinomas. Nuclear Medicine studies, such as; bone scan, renal scan (to assess renal function prior to resection of renal tumors), 1-131 MIBG (for diagnostic and therapeutic approach), F-18 DOPA PET, F-18 FDG are increasingly valuable in VHL. PET with F-18 FDG provides an indication of metabolic activity of tumors. Conclusions: In VHL, tumors can be found at various sites. Numerous imaging modalities, including US, CT, MRI, bone and 1-131 MIBG scintigraphy and angiography should be used together to demonstrate all foci. However, FDG PET/CT as a whole body imaging modality

    Objective Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. Design Retrospective, single institution study. Subjects 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. Methods Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery chemosurgery (Melphalan, Carboplatin, Topotecan, Methotrexate) delivered in the same initial session to both naïve and previously treated eyes. Main Outcome Measures Ocular survival, metastatic disease, patient survival from metastases, second cancers, systemic adverse effects, need for transfusion of blood products, electroretinogram before and after treatment. Results 116 eyes were salvaged (4 eyes were enucleated: 3 because of progressive disease, 1 family choice). Kaplan Meier ocular survival was 99.2% at one year, 96.9% at 2 and 3 years and 94.9% for years 4 through 7. There were no cases of metastatic disease or metastatic deaths with a mean follow-up of 3.01 years. Two children developed second cancers (both pineoblastoma) and one of them died. Transfusion of blood products was required in 3 cases (4 transfusions), 1.9%. Two children developed fever/neutropenia requiring hospitalization (0.95%). ERGs were improved in 21.6% and unchanged after treatment in 52.5% of cases (increase or decrease of less than 25μV). Conclusions Bilateral ophthalmic artery chemosurgery is a safe and effective technique for managing bilateral retinoblastoma-even when eyes are advanced bilaterally, and if both eyes have progressed after systemic chemotherapy. Ocular survival was excellent (94.9% at 8 years), there were no cases of of metastatic disease and no deaths from metastatic disease, but children remain at risk for second cancers. In 21.6% of cases ERG function improved. Despite using chemotherapy in both eyes in the same session, systemic toxicity was low. PMID:27258771

Case: This is the case of a 49-year-old man diagnosed with squamous cell carcinoma of the face, scheduled for resection. Preoperative radiographs revealed a left upper lobe mass, found to be squamous cell carcinoma. Diagnosis was changed to Stage IV primary lung cancer. The patient did not undergo resection. Discussion: No previous cases of primary lung cancer presenting as a malar mass have been reported. Facial lesions can be the presenting feature of primary lung cancer. Discovery of the true primary lesion can alter therapy and prognosis.

    It is not readily apparent how pulmonary function could be improved by resecting portions of the lung in patients with emphysema. In emphysema, elevation in residual volume relative to total lung capacity reduces forced expiratory volumes, increases inspiratory effort, and impairs inspiratory muscle mechanics. Lung volume reduction surgery (LVRS) better matches the size of the lungs to the size of the thorax containing them. This restores forced expiratory volumes and the mechanical advantage...

    In the last 10-15 years, strategies and modalities of lung cancer treatment have changed dramatically. Meanwhile, the treatment objectives, the lung cancers themselves, have also changed, probably owing to early detection by computed tomography and aging of the population. In particular, the proportions of smaller lung cancers, lung adenocarcinomas with ground-glass opacity, and lung cancers in older patients are increasing. Along with these changes, surgeons have innovated and evaluated novel procedures for pulmonary resection. These include the application of minimally invasive surgical techniques, such as video-assisted thoracoscopic surgery (VATS) and robotic surgery, and sub-lobar resection, such as wedge resection and segmentectomy, for small peripheral lung cancers. Currently, VATS has gained wide acceptance and several institutions in Japan have started using robotic surgery for lung cancers. Two important clinical trials of sub-lobar resection for small peripheral lung cancers are now underway in Japan. In addition, surgery itself is of growing importance in lung cancer treatment. In particular, recent evidence supports the use of surgery in strictly selected patients with locally advanced disease, lung cancers with N2 lymph node metastases, small cell lung cancers, recurrent oligo-metastasis after pulmonary resection, or relapsed tumors after drug treatment. Surgical treatment also provides abundant tumor samples for molecular analysis, which can be used for drug selection in the adjuvant setting or after disease relapse. In the era of personalized treatment, surgery is still one of the most important treatment modalities to combat lung cancer. PMID:25453375

    Müllerian cysts in the mediastinum were first described by Hattori in 2005 [1]. We report the first known case of multiple müllerian cysts in the thorax in a 35-year-old woman with cough and an abnormal chest roentgenogram. Multiple bilateral cysts were resected thoracoscopically. Histologic examination showed benign ciliated tubal epithelium that stained positive with immunohistochemical stains for estrogen receptor (ER), cancer antigen 125 (CA-125), Wilms' tumor protein 1 (WT-1), and paired box gene 8 (PAX8), confirming müllerian origin. We also review the embryogenesis and pathologic characteristics of müllerian cysts and the rare occurrence of their migration to the thorax. PMID:26522538

Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    1989-02-20

    Lung cancer is the leading cause of death of cancer in Australian men and the third leading cause in Australian women. Efforts are being made to reduce the incidence of this disease by smoking-cessation programmes and improved industrial hygiene, and these measures need to be encouraged strongly by all sectors of the community. On a population basis, insufficient evidence is available to justify screening procedures for the early detection of lung cancer in "at-risk" groups. Cure is possible by surgical resection in early cases. Improvements in therapeutic results with traditional cancer treatments largely have reached a plateau, but a number of newer therapies, and combinations of standard therapies, currently are being evaluated. Of particular interest is concurrent radiotherapy and chemotherapy in localized non-small-cell lung cancer; laser "debulking" in conjunction with radiotherapy in non-small-cell lung cancer, and biological response-modifying agents in non-small-cell and small-cell lung cancer. It is important that data be collected adequately to define epidemiological changes and to evaluate treatment results (including repeat bronchoscopy, to assess local control of tumour), and that the quality of life is recorded and reported in the evaluation process. Finally, phase-III studies in lung-cancer treatments require adequate numbers of subjects to enable meaningful conclusions to be achieve objectives within a reasonable study period. PMID:2469943

  7. Postoperative pneumonia after surgery for lung cancer. Clinical analysis of 23 cases

    International Nuclear Information System (INIS)

    Postoperative pneumonia is sometimes a life-threatening complication of surgery for lung cancer. We retrospectively reviewed patients who developed postoperative pneumonia after surgery for lung cancer in order to assess the clinical, microbiological, and therapeutic features of this complication. Between 2001 and 2009, 836 patients underwent pulmonary resection for lung cancer in our hospital. Postoperative pneumonia developed in 23 patients (2.8%). Diagnoses of pneumonia were performed on postoperative day 6.8±3.4 (mean± standard deviation (SD)). Plain chest radiography revealed abnormal shadows on the operative side in 20 patients; 2 patients had bilateral pneumonia and 1 underwent pneumonectomy. Computed tomography was performed in 17 patients, and, among them, 13 patients (76.5%) had infiltrative shadows in the caudal or dorsal portion of the operative side of the lung. Nine patients (39.1%) were intubated in order to perform mechanical ventilation, and 4 of them died. Sputum cultures were performed in 12 patients, and pathogenic microorganisms were isolated in 4 (33.3%). The culturing of endotracheal specimens was carried out in 12 patients; among them, normal flora of the oral cavity was isolated in 4 patients (33.3%), no microorganisms were identified in 1 patient (8.3%), and pathogenic microorganisms were isolated in 7 patients (58.3%). The patients whose specimens tested positive for pathogenic microorganisms tended to develop severe pneumonia. We conclude that the insufficient drainage of respiratory tract secretions and silent aspiration after lung surgery are associated with the development of postoperative pneumonia. Further, obtaining and analyzing lower respiratory tract secretions is an important step in the management of postoperative pneumonia. (author)

    Full Text Available The abdominoperineal resection is a procedure that combine a low anterior resection and the complete perineal excision of the anus and rectum. The paper discuss the surgical anatomy of the rectum, the history, the indications and complications of the procedure. It is also described the technique of the abdominoperineal resection: the abdominal approach is through a lower midline incision, and then, the small bowell is packed into the upper side of the abdomen. The sigmoid colon is mobilized by the incising the posterior and lateral peritoneum. The peritoneal dissection is continued distally parallel to the rectum. The inferior mesenteric artery is identified and ligated just distal to the take off of the left colic artery or higher. The next step is the total mesorectal excision, performed by entering in the retrorectal space, in the avascular space of areolar tissue, above the promontory of the sacrum and anteriorly the presacral nerves. This plane should be continued by sharp disection laterally and caudally till the pelvic floor. Anterior dissection of the rectum is achived by incision the recto-vesical reflection and dissection of the Denonvilliers fascia (in men and in women the mobilization of the rectum is finished by the incision and the dissection of the recto-vaginal reflection. The colon can be now divided proximally. The next step is the perineal resection: an eliptical incision is made to encompass the anus with an adequate margin of tissue. The skin edges are then grasped and the subcutaneous tissue is divided with cautery; the dissection is continued into the fat of the ischio-anal fossa and the inferior rectal vessels are divided. The levator ani is than divided. After the complete posterior dissection of the rectum, the specimen may be delivered into the perineal wound and then, the anteriorly final dissection can be achived. In men the dissection plane is between the rectum and the prostate / urethra, and in women between the

    2009-07-01

    Pleuropulmonary blastoma (PPB) is an aggressive tumour accounting for less than 1% of all primary malignant lung tumours in the paediatric population. It can be associated with cystic pulmonary lesions, which may be evident at the time of diagnosis or predate the appearance of the tumour. There are contradictory reports about the value of prophylactic resection of pulmonary cysts in protecting patients from developing PPB. We report an individual case where asymptomatic congenital lobar emphysema was incidentally picked up on CXR. Following a period of surveillance the lesion was resected due to increasing size. The histology of the lesion revealed PPB Type I.

    Full Text Available Caroli disease is a cystic congenital malformation of the intrahepatic biliary tract, frequently associated with lithiasis. Commonly, cystic dilatations are bilateral and infrequently they affect only one hepatic lobule or segment. We report six patients with localized Caroli disease, three in the right and three in the left hepatic lobule, that were subjected to a hepatic resection. There were no postoperative complications or mortality. After 28 months of follow up, patients are asymptomatic and with normal hepatic function and ultrasonography. The importance of diagnosing localized Caroli disease, in which hepatic resection can be curative, is emphasized (Rev Méd Chile 2003; 131: 183-9

    1987-08-01

    A patient who had disseminated vascular tumors involving the bilateral ovaries, bilateral lungs and pleura, pericardium, and mediastinum is reported. The tumors were histologically of the capillary, and partly the cavernous, type of hemangioma. However, endothelial cell growth was prominent in some areas, especially in the lung, and the histology of the lung tumor resembled epithelioid hemangioendothelioma or intravascular bronchiolo-alveolar tumor (IVBAT). In the endocardium of the right atrium, an endothelial tumorous projection was observed, and there were tiny foci of tumor cell nests in the abdominal venous wall. Small lymphangiomas were also found in the subcapsular region of the spleen. These findings suggest that there had been an abnormal proliferation of systemic endothelial cells and that tumors of endothelial cell origin with diverse histological patterns developed with this condition as a background. The autopsy finding of fibrin thrombi in multiple organs as well as laboratory data including thrombocytopenia suggest that this case belongs to the "Kasabach-Merritt syndrome." PMID:3673576

  1. Endoscopic resection of sinonasal malignancies.

    Nicolai, Piero; Castelnuovo, Paolo; Bolzoni Villaret, Andrea

    2011-04-01

    Malignant tumors of the sinonasal tract are rare, accounting for only 1% of all malignancies. Although they are associated with substantial histological heterogeneity, surgery plays a key role in their management. This review addresses the evolution of current treatments in view of the introduction of endoscopic resection techniques. The absence of facial incisions and osteotomies, decreased hospitalization time, better control of bleeding, improved visualization of tumor borders, and reduced morbidity and mortality rate are the major advantages of endoscopic techniques in comparison to traditional external approaches. The major criticisms focus on oncologic results in view of the short/intermediate follow-up of large series, which have commonly grouped together several histologies that may be associated with different prognoses. Since prospective studies contrasting the results of endoscopic and craniofacial resections are difficult to carry out given the rarity of the disease together with ethical issues, the creation of a large database would favor the analysis of several variables related to the patient, tumor, and treatment on survival performed on a large number of patients.

    We report the resection of a vaginal septum while preserving the virginity of a 12-year-old girl with Herlyn-Werner-Wunderlich Syndrome (HWWS) having a didelphys uterus, obstructed hemivagina, and an ipsilateral renal agenesis with follow-up at 18 months. Successful resection of the vaginal septum with conservation of the hymenal ring and complete drainage of both the hematocolpos and the hematometra were achieved. Cyclic dysmenorrhea and pelvic pain were completely resolved on follow-up visits at 4, 6, and 18 months. Office hysteroscopy performed during the last follow-up visit revealed a patent vaginal vault without evidence of adenosis or recurrence of the vaginal septum. Vaginoscopy is a safe, convenient, and efficient diagnostic and therapeutic modality that can be used in the management of patients with an obstructed hemivagina. It maintains the patient's virginity and it is useful in patients with a restrictive vaginal opening or narrow vaginal canal. Furthermore, the hysteroscopic excision of the vaginal septum offers minimal risk of recurrence of the septal defect. PMID:23315718

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    2013-12-01

    Pigmented villonodular synovitis (PVNS) is a proliferative disease of synovial tissue characterized by lipid-laden macrophages, multinucleated giant cells, and hemosiderin deposits. PVNS presents either in a localized form with minimal rates of recurrence after surgical resection or in a diffuse form with an expansive growth pattern showing formation of osseous erosions and extra-articular manifestation. In the diffuse form high recurrence rates occur as a result of the challenge of achievement of total synovectomy. Typically only one single joint, being the knee in 80% of cases, is involved with diffuse PVNS. Reports of bi- or multiarticular manifestation are at best rare. Here, a case of a 16-year-old girl with bilateral diffuse PVNS of the knee allows discussion of diagnostic and treatment considerations. PMID:23288770

    We report the case of a 67-year-old male with bilateral proximal tibiofibular synostosis, presenting with unilateral symptoms. The patient complained of pain around the left fibular head, which was attributed to incomplete bone bridging between the proximal tibia and fibula; he underwent proximal fibular head resection, which alleviated the pain and improved knee mobility. Eleven months later, the patient continued to be pain-free and did not experience any adverse effects. An examination of this case and a review of similar cases revealed that participation in sport activities such as long-distance running may be one of the causes of proximal tibiofibular synostosis. In this report, we have also reconsidered the classification of proximal tibiofibular synostosis and provided information for a better understanding of this unusual condition. PMID:24915740

  12. Bilateral perinephric pseudocysts and polycystic kidneys in a ferret

    International Nuclear Information System (INIS)

    A 3-year-old castrated male domestic ferret was evaluated for abdominal distention. Survey lateral and dorsoventral abdominal radiographs were made. There were two soft tissue radiopacities consistent with grossly enlarged kidneys displacing small bowel and colon cranially, ventrally and caudally. Abdominal ultrasound was performed and revealed bilateral perinephric pseudocysts and polycystic kidneys. The perinephric pseudocysts were found to be dilated renal capsules on exploratory surgery and were drained. On follow up examinations, the pseudocysts were drained by ultrasound-guided paracentesis. The perinephric cyst fluid was distinguished from urine by measuring creatinine concentration and plans were made to resect the renal capsules due to rapid re-accumulation of pseudocyst fluid. The ferret's condition deteriorated and euthanasia was performed. Post-mortem examination was declined by the owner. Perinephric pseudocysts are rare and this is the first published report in a ferret. Ultrasound examination is the most rapid, accurate and non-invasive method for diagnosis of perinephric pseudocysts

    Bilateral facial palsy, which is usually combined with other diseases, occurs infrequently. It may imply a life-threatening condition. Therefore, the differential diagnosis of bilateral facial palsy is important. However, the etiology is variable, which makes diagnosis challenging. We report a rare case of progressive bilateral facial palsy as a manifestation of granulomatosis with polyangiitis (GPA). A 40-year-old male with otitis media and right facial palsy was referred for electroneurography (ENoG), which showed a 7.7% ENoG. Left facial palsy occurred after 2 weeks, and multiple cavitary opacities were noted on chest images. GPA was diagnosed by lung biopsy. His symptoms deteriorated and mononeuropathy multiplex developed. The possibility of systemic disease, such as GPA, should be considered in patients presenting with bilateral facial palsy, the differential diagnosis of which is summarized in this report.

    Thoracoscopic surgery can be one of less invasive surgical interventions for early stage lung cancer. Locally advanced lung cancer, however, cannot avoid aggressive procedures including pneumonectomy and/or extended combined resection of chest wall, aorta, esophagus, etc. for complete resection. Surgical approach even for advanced lung cancer can be less invasive by benefit from new anti-cancer treatment, innovated manipulations of bronchoplasty and angioplasty, and bench surgery( lung autotransplantation technique). We herein reviewed the strategy to minimize invasive interventions for locally advanced lung cancer, introducing 2 successful cases with advanced lung cancer. The 1st patient is a 62-year old man with centrally advanced lung cancer invading to mediastinum. Right upper sleeve lobectomy with one-stoma carinoplasty following induction chemoradiation therapy was successful. The operation time was 241 minutes. The performance status is good with no recurrence for 60 months after surgery. The 2nd is a 79-year old man with advanced lung cancer invading to the distal aortic arch. Left upper segmentectomy following thoracic endovascular aortic repair with stentgraft was successful with no extracorporeal circulation. The operation time was 170 minutes. The performance status is good with no recurrence for 30 months after surgery. The invasiveness of surgical interventions for local advanced lung cancer can be minimized by innovated device and new anti-cancer drugs. PMID:27440037

    Placental transmogrification is a very rare lung disease, where the alveoli resemble the chorionic villi of placenta, and this change is a characteristic finding. A 31-year-old female patient presented with cough and dyspnea that had begun 2 weeks prior to admission. Along with giant bulla found in the left upper lung field, subsegmental consolidation was also identified in the lingular segment on plain chest radiograph and CT scan. Wedge resection was performed to remove the bulla. Pathologic examination of the resected bulla revealed destruction of the normal structures and characteristic villous and papillary changes. These changes led to a diagnosis of placental transmogrification. We made an encounter of an unusual placental transmogrification which had different image findings from other reported transmogrification cases. Thus, we report an atypical placental transmogrification case where both consolidation and giant bulla coexist.

    BACKGROUND: Liver resection after liver transplantation is a relatively uncommon procedure. Indications for liver resection include hepatic artery thrombosis (HAT), non-anastomotic biliary stricture (ischemic biliary lesions), liver abscess, liver trauma and recurrence of hepatocellular carcinoma (HCC). Organ shortage and lower survival after re-transplantation have encouraged us to make attempts at graft salvage. METHODS: Eleven resections at a mean of 59 months after liver transplantation were made over 18 years. Indications for liver resection included HCC recurrence in 4 patients, ischemic cholangiopathy, segmental HAT, sepsis and infected hematoma in 2 each, and ischemic segmentⅣafter split liver transplantation in 1. RESULTS: There was no perioperative mortality. Morbidity included one re-laparotomy for small bowel perforation, one bile leak treated conservatively, one right subphrenic collection, one wound infection and 5 episodes of Gram-negative sepsis. One patient underwent re-transplantation 4 months after resection for chronic rejection. There were 3 deaths, two from HCC recurrence and one from post-transplant lymphoproliferative disorder. The overall mean follow-up after resection was 48 months. CONCLUSIONS: Liver resection in liver transplant recipients is safe, and has good outcome in selected patients and avoids re-transplantation in the majority of patients. Recipients with recurrent HCC in graft may beneift from resection, but cure is uncommon.

    Small-cell lung cancer (SCLC) comprises approximately 14% of all lung cancer cases. Most patients present with locally advanced or metastatic disease and are therefore treated nonoperatively with chemotherapy, radiotherapy, or both. A small subset of patients with SCLC present with early-stage disease and will benefit from surgical resection plus chemotherapy. The rationale for radiotherapy in these patients remains controversial. PMID:25441133

  12. Neoadjuvant chemoradiation with IMRT in resectable and borderline resectable pancreatic cancer

    International Nuclear Information System (INIS)

    Purpose: Neoadjuvant chemoradiation is an alternative to the surgery-first approach for resectable pancreatic cancer (PDA) and represents the standard of care for borderline resectable (BLR). Materials and methods: All patients with resectable and BLR PDA treated with neoadjuvant chemoradiation using IMRT between 1/2009 and 11/2011 were reviewed. Patients were treated to a customized CTV which included the primary mass and regional vessels. Results: Neoadjuvant chemoradiation was completed in 69 patients (39 BLR and 30 resectable). Induction chemotherapy was used in 32 (82%) of the 39 patients with BLR disease prior to chemoXRT. All resectable patients were treated with chemoXRT alone. Following neoadjuvant treatment, 48 (70%) of the 69 patients underwent successful pancreatic resection with 47 (98%) being margin negative (RO). In 30 of the BLR patients who had arterial abutment or SMV occlusion, 19 (63%) were surgically resected and all had RO resections. The cumulative incidence of local failure at 1 and 2 years was 2% (95% CI 0–6%) and 9% (95% CI 0.6–17%) respectively. The median overall survival for all patients, patients undergoing resection, and patients without resection were 20, 26 and 11 months respectively. Sixteen (23%) of the 69 patients are alive without disease with a median follow-up of 47 months (36–60). Conclusion: Neoadjuvant chemoXRT can facilitate a margin negative resection in patients with localized PCa

    Objectives: To compare the accuracy of prenatal ultrasonography (US) to magnetic resonance imaging (MRI) in the characterisation of congenital lung anomalies, and to assess their agreement with final diagnosis. To evaluate the influence of additional MRI information on therapeutic management. Methods: 26 prenatal congenital lung anomalies detected consecutively between 2006 and 2012 were retrospectively evaluated. Lesions were initially observed at prenatal US and further investigated with MRI. Prenatal US and MRI imaging findings, and suggested diagnosis were compared with the final diagnosis, obtained from autopsies (4), pathological evaluation following surgical resection (15) and postnatal imaging studies (7). Results: Postnatal diagnoses included 7 congenital pulmonary airway malformations, 8 complex lesions, 7 overinflations, 1 sequestration, 1 bronchogenic cyst, 1 blastoma and 1 bilateral lymphangioma. Suggested prenatal US and MRI diagnosis was correct in 34.6% and 46.2% of patients, respectively, mainly isolated lung lesions with typical imaging findings. Nonspecific imaging findings at US and MRI studies were observed in 38.4% of cases. In 42% of the operated anomalies, pathological dissection revealed the presence of complex anomalies. MRI changed the US diagnosis, but not the further management in 9.7% of the lesions. Conclusions: Prenatal US and MRI showed a high accuracy in the diagnosis of isolated congenital lung lesions with typical imaging findings. However, overall characterisation rates were low, because of both a high percentage of complex lesions and of lesions with nonspecific imaging findings. MRI was better than US in characterising complex lesions, but its additional information did not influence therapy decisions.

    Full Text Available Abstract Background Pancreatic adenocarcinoma (PCA is one of the most lethal human malignancies, and radical surgery remains the cornerstone of treatment. After resection, the overall 5-year survival rate is only 10% to 29%. At the time of presentation, however, about 40% of patients generally have distant metastases and another 40% are usually diagnosed with locally advanced cancers. The remaining 20% of patients are indicated for surgery on the basis of the results of preoperative imaging studies; however, about half of these patients are found to be unsuitable for resection during surgical exploration. In the current study, we aimed to determine the clinicopathological characteristics that predict the resectability of PCA and to conduct a prognostic analysis of PCA after resection to identify favorable survival factors. Methods We retrospectively reviewed the medical files of 688 patients (422 men and 266 women who had undergone surgery for histopathologically proven PCA in the Department of Surgery at Chang Gung Memorial Hospital in Taiwan from 1981 to 2006. We compared the clinical characteristics of patients who underwent resection and patients who did not undergo resection in order to identify the predictive factors for successful resectability of PCA, and we conducted prognostic analysis for PCA after resection. Results A carbohydrate antigen 19–9 (CA 19–9 level of 37 U/ml or greater and a tumor size of 3 cm or more independently predicted resectability of PCA. In terms of survival after resection, PCA patients with better nutritional status (measured as having an albumin level greater than 3.5 g/dl, radical resection, early tumor stage and better-differentiated tumors were associated with favorable survival. Conclusions Besides traditional imaging studies, preoperative CA 19–9 levels and tumor size can also be used to determine the resectability of PCA. Better nutritional status, curative resection, early tumor stage and well

    Objectives The aim of this analysis was to examine prognostic features and outcomes in patients undergoing resection for intrahepatic cholangiocarcinoma (ICC). Methods A retrospective chart review was performed in all patients who underwent R0 or R1 resection for primary ICC between 1995 and 2011. Clinical data were abstracted and statistical analyses were conducted in the standard fashion. Results A total of 82 patients underwent curative hepatectomy for primary ICC; 51 patients in this cohort developed recurrence. The median follow-up of survivors was 27 months (range: 1–116 months). Recurrences were intrahepatic (65%), associated with multiple tumours (54%) and occurred during the first 2 years after hepatectomy (86%). The main factor associated with recurrence after resection was the presence of satellite lesions. Overall 5-year disease-free survival after primary resection was 16%. Factors associated with poor survival were transfusion and perineural invasion. Treatment of recurrence was undertaken in 89% of patients and repeat surgical resection was performed in 15 patients. The 3-year survival rate after recurrence was 25%. Prolonged survival after recurrence was associated with a solitary tumour recurrence. Conclusions Despite curative resection of ICC, recurrence can be expected to occur in 79% of patients at 5 years. Predictors of survival and recurrence after resection vary in the literature. In patients with recurrence, selection of the optimal treatment remains challenging. PMID:25395176

    Extensive lymphangiomas of the facial skeleton result in deforming forces leading to ongoing masticatory, speech, oral hygiene, and airway problems. This paper presents a small series of patients with severe mandibular overgrowth secondary to lymphatic malformations. Following debulking of the malformations and tongue reductions, the authors describe the results of their treatment with bilateral mandibular body resections and setback. The authors' results suggest that severe functional impairment from deforming malformations can be addressed in childhood with orthognathic surgery. Improved occlusion, oral closure, and airway opening can be achieved using this procedure. PMID:27100638

    Schwannomas are benign nerve sheath tumours arising from Schwann cells. Presacral schwannomas are rare with only case report and short case series being reported in literature. Complete surgical resection is the treatment of choice for these rare tumours. Approach to surgical resection depends on the type of the tumour. Type 3 tumours have conventionally been treated with open intra or extra peritoneal approach. With improvement in the laparoscopic surgical skills, more and more complex surgical procedures have been attempted via this approach.

    2004-01-01

    Small-sized peripheral lung cancers have been detected more frequently as a result of recent developments in diagnostic imaging including high-resolution computed tomography (HRCT). Although the diagnosis of small-sized peripheral lung cancers is difficult, it makes an adequate diagnosis possible using transbronchial fine needle aspiration cytology or a new thin-type bronchoscope. Surgical treatment using mini-thoracotomy or video-assisted thoracic surgery is effective for early stage small-sized peripheral lung cancers. Lesser resection of lung cancer may provide many benefits to patients, such as preserving vital lung tissue and providing the chance for further resection if a second primary lung cancer develops, however, lobectomy with systematic hilar and mediastinal lymph node dissection should remain the standard surgical treatment, and an intentional limited resection should be adopted for very limited patients with a definitive early stage because of recurrence rates.

Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    Background The Dextroscope system by Volume Interactions (Singapore) had been applied to minimally invasive neurosurgery in many units.This system enables the neurosurgeon to interact intuitively with the three-dimensional graphics in a direct manner resembling the way one communicates with the real objects.In the paper,we explored its values in pre-operation surgical planning for intracranial meningiomas resection.Methods Brain compuled tomography (CT),magnetic resonance imaging (MRI),and magnetic resonance venography (MRV) were performed on 10 patients with parasagittal and falcine meningiomas located on central groove area; brain CT,MRI and magnetic resonance angiography (MRA) were performed on 10 patients with anterior skull base meningiomas and 10 patients with sphenoid ridge meningiomas.All these data were transferred to Dextroscope virtual reality system,and reconstructed.Then meningiomas,skull base,brain tissue,drainage vein and cerebral arteries were displayed within the system,and their anatomic relationships were evaluated.Also,the simulation operations were performed.Results For parasagittal and falcine meningiomas,the relationships of tumor with drainage vein and superior sagittal sinus were clearly displayed in the Dextroscope system.For anterior skull base and sphenoid ridge meningiomas,the relationships of tumor with bilateral internal carotid arteries,anterior cerebral arteries,middle cerebral arteries and skull base were vividly displayed within the virtual reality system.Surgical planning and simulation operation of all cases were performed as well.The real operations of all patients were conducted according to the simulation with well outcomes.Conclusions According to the virtual reality planning,neurosurgeons could get more anatomic information about meningioma and its surrounding structures,especially important vessels,and choose the best approach for tumor resection,which would lead to better prognosis for patients.

    We encountered a rare case of hypersensitivity pneumonitis associated with bilateral hilar lymphadenopathy (BHL). The patient was a 53-year-old male, who developed dry cough and shortness of breath when using a humidifier since 1982. He was admitted to our hospital for further evaluation in 1987. Chest X-ray films showed BHL and ground glass appearance in the bilateral lung fields. Pulmonary function test indicated disturbance of diffusing capacity. Transbronchial lung biopsy revealed interstitial pneumonitis, and lymph node biopsy by mediastinoscopy showed lymphoid sinus histiocytosis without noncaseating granuloma. Provocation test using the humidifier was positive, and the diagnosis of humidifier lung with BHL was made. PMID:1507691

  1. Lung volume reduction for severe emphysema: do we need a scalpel or a scope?

    Directory of Open Access Journals (Sweden)

    2010-09-01

    Full Text Available Resectional lung volume reduction has proven to be superior to medical treatment in reducing dyspnoea and in increasing lung function, survival and quality of life in a very well selected, low risk group of hyperinflated patients with heterogeneous emphysema predominantly in the upper lobe. Nevertheless, this intervention is hampered by an important pulmonary (30% and cardiovascular (20% morbidity, mainly as a result of prolonged (>7 days air leak, and a 5% risk of death as a result of the surgical intervention. Results from ongoing randomised trials are awaited in order to determine whether less invasive, non-resectional lung volume treatment of emphysema via the bronchoscope using endobronchial valves, airway bypass stents or biological adhesives/heated water vapour will yield similar improvement with less morbidity and reduced mortality, compared with surgical resection. Furthermore, it is hoped that endoscopic lung volume reduction techniques may help patients with homogeneous emphysema currently excluded by most teams for the resectional procedure.

    2013-03-01

    Full Text Available The aim of the investigation was to develop ultrasonic techniques of the resected liver, pancreas, and kidney, and study their normal echosemiotics after different types of resection. Materials and Methods. We examined 404 patients after various hepatectomies, 145 — after extended pancreaticoduodenal resections, and 123 — after different types of nephrectomy. Ultrasound was performed on scanners Voluson 730 PRO (GE, USA and Technos (Esaote, Italy in early postoperative period — on day 2–3 and on day 7–10, and in follow-up care — 3, 6 and 12 months after the operation. Results. We developed an ultrasound technique and established sonographic criteria to assess resected parenchymatous organs, represented normal ultrasound semiotics of the liver, pancreas and kidney after different types of resection. The number and location of hepatic veins in hepatic stump was found to be of primary importance in determining the hepatectomy type; and it was called the hepatic vein rule. An additional criterion was the portal vein branching character. The assessment criteria of pancreatic stump were its size in the body of pancreas and diameter of the major pancreatic duct, as well as spatial location of anastomosed loop of jejunum and gastric remnant. During the first postoperative month slight dilatation of Wirsung duct up to 3–4 mm with its following recovery is permissible. In late postoperative period, the duct dilatation over 3 mm is considered pathological. To determine the nephrectomy type it is necessary to assess the form of the organ and the resection area. Normal echogram can be misinterpreted after frontal nephrectomy due to different parenchymal thickness in its resected and remaining parts. Conclusion. The developed echosemiotics of resected parenchymatous organ in the majority of cases enables to take a correct view of the volume and character of the surgery, and determine postoperative state of the stump.

    2016-05-18

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in China. The Barcelona Clinic Liver Cancer (BCLC) staging system is regarded as the gold standard staging system for HCC, classifying HCC as early, intermediate, or advanced. For intermediate HCC, trans-catheter arterial chemoembolization (TACE) is recommended as the optimal strategy by the BCLC guideline. This review investigates whether liver resection is better than TACE for intermediate HCC. Based on published studies, we compare the survival benefits and complications of liver resection and TACE for intermediate HCC. We also compare the survival benefits of liver resection in early and intermediate HCC. We find that liver resection can achieve better or at least comparable survival outcomes compared with TACE for intermediate HCC; however, we do not observe a significant difference between liver resection and TACE in terms of safety and morbidity. We conclude that liver resection may improve the short- and long-term survival of carefully selected intermediate HCC patients, and the procedure may be safely performed in the management of intermediate HCC.

    Pancreatic cancer is the fourth most common cause of cancer death in the United States. Surgery remains the only curative option; however only 20% of the patients have resectable disease at the time of initialpresentation. The definition of borderline resectable pancreatic cancer is not uniform but generally denotes to regional vessel involvement that makes it unlikely to have negative surgical margins. The accurate staging of pancreatic cancer requires triple phase computed tomography or magnetic resonance imaging of the pancreas. Management of patients with borderline resectable pancreatic cancer remains unclear. The data for treatment of these patients is primarily derived from retrospective single institution experience. The prospective trials have been plagued by small numbers and poor accrual. Neoadjuvant therapy is recommended and typically consists of chemotherapy and radiation therapy. The chemotherapeutic regimens continue to evolve along with type and dose of radiation therapy. Gemcitabine or 5-fluorouracil based chemotherapeutic combinations are administered. The type and dose of radiation vary among different institutions. With neoadjuvant treatment, approximately 50% of the patients are able to undergo surgical resections with negative margins obtained in greater than 80% of the patients. Newer trials are attempting to standardize the definition of borderline resectable pancreatic cancer and treatment regimens. In this review, we outline the definition, imaging requirements and management of patients with borderline resectable pancreatic cancer.

    Full Text Available Bilateral ovarian tumour in a girl presents the dilemma of conservative versus aggressive approach towards these tumours. When faced with suspicious tumour and complete replacement of the ovaries bilaterally, bilateral oophorectomy is a viable option, though the certain possibility of infertility and lifelong hormonal supplementation is unavoidable. We report a case of bilateral ovarian masses in a young girl, which on histopathological examination showed mature teratoma with aggregates of proliferating capillary and cavernous sized vessels in the tumour wall. Such associations are rare and must be differentiated from a vascular neoplasm.

    To determine if the presence of bilateral implants, in addition to other anatomic and treatment-related variables, affects coverage of the target volume and dose to the heart and lung in patients receiving postmastectomy radiation therapy (PMRT). A total of 197 consecutive women with breast cancer underwent mastectomy and immediate tissue expander (TE) placement, with or without exchange for a permanent implant (PI) before radiation therapy at our center. PMRT was delivered with 2 tangential beams + supraclavicular lymph node field (50 Gy). Patients were grouped by implant number: 51% unilateral (100) and 49% bilateral (97). The planning target volume (PTV) (defined as implant + chest wall + nodes), heart, and ipsilateral lung were contoured and the following parameters were abstracted from dose-volume histogram (DVH) data: PTV D{sub 95%} > 98%, Lung V{sub 20}Gy > 30%, and Heart V{sub 25}Gy > 5%. Univariate (UVA) and multivariate analyses (MVA) were performed to determine the association of variables with these parameters. The 2 groups were well balanced for implant type and volume, internal mammary node (IMN) treatment, and laterality. In the entire cohort, 90% had PTV D{sub 95%} > 98%, indicating excellent coverage of the chest wall. Of the patients, 27% had high lung doses (V{sub 20}Gy > 30%) and 16% had high heart doses (V{sub 25}Gy > 5%). No significant factors were associated with suboptimal PTV coverage. On MVA, IMN treatment was found to be highly associated with high lung and heart doses (both p < 0.0001), but implant number was not (p = 0.54). In patients with bilateral implants, IMN treatment was the only predictor of dose to the contralateral implant (p = 0.001). In conclusion, bilateral implants do not compromise coverage of the target volume or increase lung and heart dose in patients receiving PMRT. The most important predictor of high lung and heart doses in patients with implant-based reconstruction, whether unilateral or bilateral, is treatment of

  2. Extended Resection of Chest Wall Tumors with Reconstruction Using Poly Methyl Methacrylate-Mesh Prosthesis

    International Nuclear Information System (INIS)

    This prospective study evaluates the early result of patients with massive chest wall tumors treated by extended resection and reconstruction using Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis. Material and Methods: This surgery was performed on 40 patients with a mean age of 45±18 (12-62) at the Department of Surgery, National Cancer Institute, Cairo University between 1998-2001. Primary chest wall tumors were the indications of surgery in 42.5%, while secondary involvement extending from other sites principally breast cancer were the indications for 57.5%. In 85% of patients more than 3 ribs were involved by tumors and lesions were more than 10 cm in the greatest dimension in 50% of cases. Resection involved sternum in 15 (37.5%) cases and in 45% of cases complete extensive rib resections extended between costovertebral junctions and the costochondral junctions were performed. Additional resections of nearby organs were needed in 20 (50%) of cases including partial lung resection in 14 cases, partial vertebral resection in 3 cases and diaphragm resection for 3 cases. Immediate bony reconstruction by inserting Prolene or Marlex mesh-enforced with Poly Methyl Methacrylate Bone Cement (PMMC) prosthesis to the resulting chest wall defect was performed in 36 cases, whereas, 4 cases had delayed reconstruction. Primary simple soft tissue closure was sufficient for 37.5% of patients; whereas 35% were covered by local rotational flap and 27.5% needed myocutaneous flaps. No patient with this immediate reconstruction needed ventilatory support or tracheostomy and flail chest was not noticed ICU stay was markedly reduced; whereas 85% required less than 7 days. Immediate post operative (40 days) complications were found in 14 patients (35%) and cases with additional lung resection had more complication rate than others (64% vs 19%). Infection occurred in 3 patients and conservative treatment for 3-4 weeks using frequent

    Metastatic adenocarcinoma in bilateral cerebellopontine angles (CPA) is rare. We report a case and review the current literature in order to enhance recognition of metastatic adenocarcinoma in the cerebellopontine angle. A 44-year-old man was referred to the hospital with rightsided diminished hearing for 7 weeks, left-sided facial palsy for 2 weeks, and left-sided sensorineural hearing loss for 1 week. On Magnetic Resonance Imaging (MRI) two tumors in bilateral CPAs were detected. The left-sided tumor was resected and histopathological examination revealed an adenocarcinoma. Many investigations could not find the primary tumor. One should be careful with middle-aged or elderly patients with sudden progressive deficits in the VIII th or VII th cranial nerves, particularly in bilateral CPA. PMID:26617145

    Full Text Available Milia en plaque (MEP is an extremely rare form of milia that is characterized by a number of milia-like cysts on an erythematous base and histologically exhibits features of keratin cysts. The etiology is not exactly known. MEP is generally seen among middle-aged women and especially on the head and neck region. Many of the diagnosed cases are localized in the retroauricular region, eyelids and the nose region. To date, no case of MEP in the auricula has been reported in the literature. In this article, we present the case of a 71-year-old female patient clinically and histologically diagnosed with bilateral auricular milia en plaque (in the external ear canal in the light of current literature.

Clinical findings and complementary studies suggested a bilateral atherogenic embolic event. Initially, she presented a superior branch retinal artery occlusion in her right eye followed by a central retinal artery occlusion with cilioretinal artery sparing in her left eye. Some conservative maneuvers performed did not improve visual acuity in the left eye. Supra-aortic Doppler ultrasonography revealed mild right internal carotid artery stenosis and moderate left internal carotid artery stenosis with a small, smooth, and homogeneous plaque. The transthoracic echocardiography showed a severe calcification of the mitral valve with a mild-moderate rim of stenosis. Central retinal artery occlusion and branch retinal artery occlusion are characterized by painless monocular loss of vision. Clinical approach and management attempt to treat the acute event, find the source of the vascular occlusion, and prevent further vascular events from occurring. Giant cell arteritis is a potentially treatable cause of central retinal artery occlusion and should be excluded in every single patient over 50 years old.Keywords: loss of vision, branch retinal artery occlusion, central retinal artery occlusion, Hollenhorst plaque

    BACKGROUND: Coronoid process hyperplasia is an uncommon finding, characterized by an enlargement of the coronoid process, causing a mechanical obstacle by its interposing in the posterior portion of the maxilla or zygomatic arch. CASE PRESENTATION: The article presents a case report of a bilateral coronoid process hyperplasia in a 3-year-old girl demonstrated with inability to open the mouth and restricted jaw movement. Panoramic x-ray and 3-dimensional computed tomographic reconstruction showed bilateral elongation of the coronoid processes associated with deformation of the mandibular condyle with no involvement of the articular space. A coronoid resection by intraoral approach was done, followed by an aggressive physiotherapy. A considerable improvement in mouth opening of 30 mm was achieved. We strongly suggest early surgical treatment of coronoid hyperplasia to recover morphology and function consequently to reduce skeletofacial deformities in young patients. CONCLUSIONS: The article presents a clinical and surgical case of bilateral coronoidectomy in a 3-year-old girl, with retrognathic mandible. The diagnosis of bilateral coronoid process hyperplasia was confirmed, and the surgical treatment was under general anesthesia, with nasotracheal intubation guided by a nasofiber endoscope, using an intraoral approach.

    Granulomatosis with polyangiitis is autoimmune and rare disease. It affects many organs, but the most often affected organs are the nose, lungs, and kidneys. It is part of vasculitis and causes an autoimmune attack by an abnormal type of circulating antibody termed ANCAs against small blood vessels. Disease concerns both men and women with a peak age of presentation in the sixth and seven decades. Typically upper and lower respiratory tract and kidneys are involved. Otitis externa, otitis media, or mastoiditis rarely occurs in granulomatosis with polyangiitis. Deafness is the most dangerous aural complication. Histological examination of biopsy is often not specific. A case of GPA with bilateral otitis media, bilateral deafness, and bilateral facial palsy with fatal course is presented. PMID:27493820

    We report a case of bilateral complete failure of adduction following bilateral translid antralethmoidal orbital decompression. We believe the probable mechanism is neuropraxia (temporary dysfunction) of the third cranial nerves' supply to the medial recti, owing to these nerves' occupying an anatomically abnormal position. Partial recovery of adduction occurred over the ensuing six months.

    Full Text Available Simultaneous bilateral spontaneous pneumothorax is a very rare clinical event, comprising approximately 1% of all spontaneous pneumothoraces. Clinical signs and symptoms may vary from mild chest pain and dyspnea to severe respiratory failure; nevertheless immediate treatment is mandatory as this condition can deteriorate and progress to tension pneumothorax. An underlying lung disease has been commonly described; in most istances primary or secondary tumors, interstitial diseases, and infectious diseases. Birt-Hogg-Dubè syndrome is a rare inherited disorder clinically characterized by multiple fibrofolliculomas, renal tumors, lung cysts, and, in ~24% of the patients, occurrence of spontaneous pneumothorax. In this case, we firstly report the concurrence of these rare conditions, as a patient presenting a simultaneous bilateral spontaneous pneumothorax was diagnosed with Birt-Hogg-Dubè syndrome based on the typical radiological findings and genetic testing of the folliculin gene located on chromosome 17.

    has a role only in selected cases. Our objectives are to describe clinical features, diagnostic methods and role of surgical treatment in patients with PA VM. Methods: Retrospective review of all patients with PA VM, in whom surgery was performed in our institution, from February 2005 to February 2010. The follow up controls were done through physician or telephone contact. Results: 8 patients, six females (3:1, aged between 16-68 years were analyzed. Most common sigiis and symptoms were dyspnea, cyanosis and clubbing. Right lower lobe was the most frequent location. Four had multiple PA VM and four met criteria for Rendu-Osler- Weber disease. Six patients had polycythemia and two anemia. Radiography was abnormal in all and computed tomography defined anatomy in seven. Angiography was performed in three, two had contrasted echocardiography and four had scintigraphy. Most common surgical treatment was lobectomy. Indications for surgery were the size of PA VM in five cases, failure of embolization in two and one because of intra-operative findings, without a previous diagrwsis. One had postoperative bleeding. Discharge was between day 2 and 10 days after surgery. There was no mortality. At their last control all patients were asymptomatic. Conclusion: PA VMpresents a wide and varied range of clinical and anatomical findings. They can cause major symptoms and serious complications, which justify their treatment. The preoperative study is based primarily on demonstrating the shunt and determining the anatomical characteristics of the lesion. In selected cases lung resection surgery is indicated.

  20. Pulmonary endothelial dysfunction induced by unilateral as compared to bilateral thoracic irradiation in rats

    International Nuclear Information System (INIS)

    Rats were sacrificed 2 mo after a single dose of 10-30 Gy of /sup 60/Co gamma rays delivered to either a right unilateral or a bilateral thoracic port. Four indices of lung endothelial function were measured: the activities of angiotensin converting enzyme (ACE) and plasminogen activator (PLA), and the production of prostacyclin (PGL/sub 2/) and thromboxane (TXA/sub 2/). The experimental results are given. These data indicate that pulmonary endothelial dysfunction induced by hemithoracic irradiation represents a direct response of a endothelium to injury, and is not secondary to other phenomena such as shunting of function to the contralateral lung

  1. Peri-operative chemotherapy in the management of resectable colorectal cancer pulmonary metastases

    International Nuclear Information System (INIS)

    Surgery is often advocated in patients with resectable pulmonary metastases from colorectal cancer (CRC). Our study aims to evaluate peri-operative chemotherapy in patients with metastastic CRC undergoing pulmonary metastasectomy. Patients treated for CRC who underwent pulmonary metastasectomy by a single surgeon were identified. Outcome measures included survival, peri-operative complications, radiological and histological evidence of chemotherapy-induced lung toxicities. Between 1997 and 2009, 51 eligible patients were identified undergoing a total of 72 pulmonary resections. Thirty-eight patients received peri-operative chemotherapy, of whom 9 received an additional biological agent. Five-year overall survival rate was 72% in the whole cohort - 74% and 68% in those who received peri-operative chemotherapy (CS) and those who underwent surgery alone (S) respectively. Five-year relapse free survival rate was 31% in the whole cohort - 38% and ≤18% in CS and S groups respectively. Only 8% had disease progression during neoadjuvant chemotherapy. There were no post-operative deaths. Surgical complications occurred in only 4% of patients who received pre-operative chemotherapy. There was neither radiological nor histological evidence of lung toxicity in resected surgical specimens. Peri-operative chemotherapy can be safely delivered to CRC patients undergoing pulmonary metastasectomy. Survival in this selected group of patients was favourable

    DNA double-strand breaks (DSBs), which arise following exposure to a number of endogenous and exogenous agents, can be repaired by either the homologous recombination (HR) or non-homologous end-joining (NHEJ) pathways in eukaryotic cells. A vital step in HR repair is DNA end resection, which generates a long 30 single-stranded DNA (ssDNA) tail that can invade the homologous DNA strand. The generation of 30 ssDNA is not only essential for HR repair, but also promotes activation of the ataxia telangiectasia and Rad3-related protein (ATR). Multiple fac-tors, including the MRN/X complex, C-terminal-binding protein interacting protein (CtIP)/Sae2, exonuclease 1 (EXO1), Bloom syndrome protein (BLM)/Sgs1, DNA2 nuclease/helicase, and several chromatin remodelers, cooperate to complete the process of end resection. Here we review the basic machinery involved in DNA end resection in eukaryotic cells.

  9. Hepatic resection and regeneration. Past and present

    International Nuclear Information System (INIS)

    Hepatic surgery has been performed on condition that the liver regenerates after hepatic resection, and the development of liver anatomy due to Glisson, Rex, and Couinaud has thrown light on hepatic surgery Understanding of feeding and drainage vessels became feasible for systemic hepatic resection; however, it seems to have been the most important problem to control the bleeding during hepatic resection. New types of devices such as cavitron ultrasonic surgical aspirator (CUSA) and Microwave coagulation were exploited to control blood loss during hepatic surgery. Pringle maneuver for exclusion feeding vessels of the liver and the decrease of central venous pressure during anesthesia enabled further decrease of blood loss. Nowadays, 3D-CT imaging may depict feeding and drainage vessels in relation to liver mass, and surgeons can simulate hepatic surgery in virtual reality before surgery, allowing hepatectomy to be performed without blood transfusion. Thus, hepatic resection has been a safe procedure, but there's been a significant research on how much of the liver can be resected without hepatic failure. A prediction scoring system based on ICGR15, resection rates, and age is mostly reliable in some criteria. Even if hepatectomy is performed with a good prediction score, the massive bleeding and associated infection may induce postoperative hepatic failure, while the criteria of postoperative hepatic failure have not yet established. Hepatic failure is supposed to be induced by the apoptosis of mature hepatocytes and necrosis originated from microcirculation disturbance of the liver. Prostaglandin E1 for the improvement of microcirculation, steroid for the inhibition of cytokines inducing apoptosis, and blood purification to exclude cytokines have been tried separately or concomitantly. New therapeutic approaches, especially hepatic regeneration from the stem cell, are expected. (author)

  10. Urinary function following resection for rectal cancer with preoperative radiation therapy

    International Nuclear Information System (INIS)

    Urinary function was evaluated after personal interview in 34 patients and after examination of the results of a urodynamic study in 15 of these, in whom resection for carcinoma of the rectum with preoperative irradiation therapy was performed. From the results of the personal interview, urinary urgency was found to have occurred in 19.2% when preoperative radiation was over. Urinary function after surgery was preserved in the group of patients who had undergone bilateral and unilateral pelvic plexus nerve preserving operations, whereas urinary dysfunction occurred in 66.7% of the group of patients who had undergone operations without pelvic plexus nerve preservation. Urinary dysfunction was recognized in 53.9% of the group of patients who had undergone abdominoperineal resection, but in none of the group of patients who had undergone low anterior resection. The urodynamic study showed that 21.4% had residual urinary output of more than 40 ml, 23.1% had the first desire to void at less than 100 ml, 15.4% had the maximum desire to void at less than 200 ml, 28.6% had compliance of the bladder at less than 20 ml/cmH2O when preoperative irradiation was over, and these data became worse 1 month after surgery. However, these phenomena were improved 1 year after surgery. (author)

    Breast hypertrophy is often associated with functional limitations. Beyond the aesthetic concerns, breast reduction can improve symptoms and self-esteem. In different countries, health-care system regulations have fixed the threshold for reimbursement in 500 g of predicted tissue resection for each breast. Different preoperative measurements have been proposed to predict breast-tissue weight to be removed, showing a variable correlation with post-operative evaluation. We describe a reliable, simple measurement to predict the quantity of breast reduction in grams, which can be applicable to any surgical technique. A total of 128 patients undergoing bilateral breast reduction were evaluated. The correlation between the preoperative nipple-areola complex (NAC) lift distance and the weight of removed breast tissue was tested with linear regression and Pearson's test. Other anthropometric measurements were tested as a control. The ratio between resected grams and lift distance was explored to find a multiplication coefficient to be used at preoperative planning. The mean resection weight was 686.65 g. The mean NAC-lift distance was 7.6 cm. Positive correlation between the NAC-lift distance and the weight of breast tissue removed was found (r: 0.87; p 12 cm of lift distance. The NAC-lift distance is a single, objective, repeatable measure that can provide a reliable prediction of breast-tissue grams to be removed; it helps in classifying breast-reduction indications.

    Full Text Available OBJECTIVE: The main utility of 18-fluorodeoxyglucose positron emission tomography (FDG-PET lies in the staging of lung cancer. However, it can also be used to differentiate indeterminate pulmonary lesions, but its impact on the resection of benign lesions at surgery is unknown. The aim of this study was to compare the prevalence of benign lesions at thoracotomy carried out for suspected lung cancer, before and after the introduction of PET scanning in a large thoracic surgical centre. MATERIALS AND METHODS: We reviewed our prospectively recorded surgical database for all consecutive patients undergoing thoracotomy for suspected or proven lung cancer and compared the prevalence of benign lesions in 2 consecutive 2-year groups, before (group I and after (group II the introduction of FDG-PET scan respectively. RESULTS: Surgical resection was performed on 1233 patients during the study period. The prevalence of benign lesions at surgery in groups I and II was similar (44/626 and 41/607, both 7%, and also in group II between those who underwent FDG-PET scan and the remainder (21/301 and 20/306 respectively, both 7%. In group II, of the 21 patients with benign lesions, who underwent FDG-PET, 19 had a false positive scan (mean standardised uptake value 5.3 [range 2.6-12.7]. Of these, 13 and 4 patients respectively had non-diagnostic bronchoscopy and percutaneous transthoracic lung biopsy pre thoracotomy. There was no difference in the proportion of different benign lesions resected between group I and those with FDG-PET in group II. CONCLUSION: The introduction of FDG-PET scanning has not altered the proportion of patients undergoing thoracotomy for ultimately benign lesions, mainly due to the avidity for the isotope of some non-malignant lesions. Such false positive results need to be considered when patients with unconfirmed lung cancer are contemplated for surgical resection.

Materials and methods: we reviewed our prospectively recorded surgical database for all consecutive patients undergoing thoracotomy for suspected or proven lung cancer and compared the prevalence of benign lesions in 2 consecutive 2-year groups, before (group I) and after (group II) the introduction of FDG-PET scan respectively. Results: Surgical resection was performed on 1233 patients during the study period. The prevalence of benign lesions at surgery in groups I and II was similar (44/626 and 41/607, both 7%), and also in group II between those who underwent FDG-PET scan and the remainder (21/301 and 20/306 respectively, both 7%). In group II, of the 21 patients with benign lesions, who underwent FDG-PET, 19 had a false positive scan (mean standardised uptake value 5.3 [range 2.6-12.7]). Of these, 13 and 4 patients respectively had non-diagnostic bronchoscopy and percutaneous transthoracic lung biopsy pre thoracotomy. There was no difference in the proportion of different benign lesions resected between group I and those with FDG-PET in group II. Conclusion: the introduction of FDG-PET scanning has not altered the proportion of patients undergoing thoracotomy for ultimately benign lesions, mainly due to the avidity for the isotope of some non-malignant lesions. Such false positive results need to be considered when patients with unconfirmed lung cancer are contemplated for surgical resection. (author)

    A non-communicating rudimentary horn is an uncommon site for ectopic pregnancy. Rudimentary horn pregnancy (RHP) is a rare entity but associated with grave clinical consequences. Majority of these cases if not detected timely end up in uterine rupture and present as an obstetrical emergency. We present this case of a 32-year-old, third gravida with a 12 weeks live gestation in the right rudimentary horn, which was successfully managed with laparoscopic resection. Early diagnosis is the key stone in the management of such cases. Laparoscopic resection is a safe and viable option in the surgical management of unruptured RHP. PMID:26085754

    AIM: To evaluate survival in patients undergoing palliative resection versus non-resection surgery for primary colorectal cancer in a retrospective analysis.METHODS: Demographics, TNM status, operating details and survival were reviewed for 67 patients undergoing surgery for incurable colorectal cancer. Palliative resection of the primary tumor was performed in 46 cases in contrast to 21 patients with non-resection of the primary tumor and bypass surgery. Risk factors for postoperative mortality and poor survival were analyzed with univariate and multivariate analyses.RESULTS: The two groups were comparable in terms of age, gender, preoperative presence of ileus and tumor stage. Multivariate analysis showed that median survival was significantly higher in patients with palliative resection surgery (544 vs 233 d). Differentiation of the tumor and tumor size were additional independent factors that were associated with a significantly poorer survival rate.CONCLUSION: Palliative resection surgery for primary colorectal cancer is associated with a higher median survival rate. Also, the presence of liver metastasis and tumor size are associated with poor survival. Therefore,resection of the primary tumor should be considered in patients with non-curable colon cancer.

    We report herein a case of invasive thymoma simultaneously associated with lung cancer. A 64-year-old man presented with a cough and anterior chest pain, and preoperative examinations revealed an anterior mediastinal tumor as well as lung cancer. The patient underwent a total thymectomy, partial resection of the right lung, left lower lobectomy, and mediastinal lymph node dissection, followed by radiotherapy. Although it is well known that thymomas may be accompanied by nonthymic cancers, invasive thymomas occurring coincidentally with lung cancer are rarely reported in Japan. This case is very interesting in its relation to the oncogenesis of thymomas. PMID:11428602

  1. Pulmonary endothelial dysfunction induced by unilateral as compared to bilateral thoracic irradiation in rats

    International Nuclear Information System (INIS)

    Rats were sacrificed 2 months after a single dose of 10-30 Gy of 60Co gamma rays delivered to either a right unilateral or a bilateral thoracic port. Four indices of lung endothelial function were measured: the activities of angiotensin-converting enzyme (ACE) and plasminogen activator (PLA) and the production of prostacyclin (PGI2) and thromboxane (TXA2). The number of macrophages recovered by bronchoalveolar lavage (BAL) and the degree of right ventricular hypertrophy (an index of pulmonary hypertension) also were determined. Right lung ACE and PLA activity decreased linearly, and PGI2 and TXA2 production increased linearly with increasing radiation dose. The response curves for right unilateral and bilateral thoracic irradiation were not significantly different. In contrast, bilateral irradiation was more toxic than unilateral, since rats exposed to the former exhibited decreased body weight, an increased incidence of pleural effusions, an increase in the number of macrophages recovered by BAL, and right ventricular hypertrophy. These data demonstrate that pulmonary endothelial dysfunction induced by hemithorax irradiation represents a direct response of the endothelium to radiation injury and is not secondary to other phenomena such as shunting of function to the shielded lung

    AIM: To investigate prognostic factors of survival following curative, non-palliative surgical removal of lung metastases secondary to colorectal cancer (CRC). METHODS: Between 1999 and 2009, a radical metastasectomy with curative intent was performed on lung metastases in 21 patients with CRC (15 male and 6 female; mean age: 57.4 ± 11.8 years; age range: 29-74 years) who had already undergone primary tumour resection. RESULTS: The mean number of lung metastases ranged from one to five. The mean overall survival was 71 ± 35 mo (median: 25 mo). After adjusting for potential confounders, multivariable Cox regression analyses predicted only the number of lung metastases (1 vs ≥ 2; hazard ratio: 7.60, 95% confidence interval: 1.18-17.2, P = 0.03) as an independent predictor of poor survival following lung resection for metastatic CRC. CONCLUSION: Resection of lung metastases is a safe and effective treatment in selected CRC patients with single lung metastases. PMID:22363137

    Full Text Available Abstract Background The retroperitoneal margin is frequently microscopically tumour positive in non-curative periampullary adenocarcinoma resections. This margin should be evaluated by serial perpendicular sectioning. The aim of the study was to determine whether retroperitoneal margin involvement independently predicts survival after pancreaticoduodenectomy within a framework of standardized assessment of the resected specimens. Methods 114 consecutive macroscopically margin-free periampullary adenocarcinomas were examined according to a prospective standardized protocol for histopathologic evaluation. The retroperitoneal margin was assessed by serial perpendicular sectioning. The periampullary cancer origin (pancreas, ampulla, distal bile duct or duodenum was registered prospectively and reevaluated retrospectively. Associations between histopathologic factors were evaluated by Chi-square test, Fisher's exact test, Kruskal-Wallis test, and Mann-Whitney test, as appropriate. Survival curves were calculated by the Kaplan-Meier method and compared using the log-rank test. Associations between histopathologic factors and survival were also evaluated by unadjusted and adjusted Cox regression analysis, including stepwise variable selection, in order to identify factors that independently predict a poor prognosis after periampullary adenocarcinoma resections.

    Full Text Available We report the case of a 25-year-old male patient who presented with bilateral panophthalmitis as the initial ocular manifestation of dengue fever. The diagnosis was a little confusing as he initially presented with features suggestive of retrobulbar hemorrhage secondary to his very low platelet count, which is a common feature of dengue fever. Ophthalmic complications are usually seen in young adults who often present at the nadir of thrombocytopenia. Ocular findings may include anterior uveitis, vitritis, retinal hemorrhages, retinal vascular sheathing, yellow subretinal dots, retinal pigment epithelium (RPE mottling, foveolitis that is clinically seen as a round subretinal yellowish lesion at the fovea, retinochoroiditis, choroidal effusion, optic disc swelling, optic neuritis, neuroretinitis, and oculomotor nerve palsy. [1] There is only one reported case of unilateral endogenous panophthalmitis due to dengue fever. Hence, clinicians and ophthalmologists have to be aware of this vision-threatening complication of dengue for early recognition and prompt treatment to save the vision of these young patients and prevent morbidity.

  7. Bilateral symmetry across Aphrodite Terra

    International Nuclear Information System (INIS)

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra

    Full Text Available Leptospirosis is a zoonosis of worldwide occurrence caused by the spirochete Leptospira interrogans. It is an acute feverish disease with a broad clinical spectrum and follows a characteristic biphasic course. Bilateral facial palsy is a rare clinical condition and the differential diagnosis of its causes is extensive. The objective of this exploratory study, presented as a case report, is to describe the occurrence of bilateral facial palsy as an unusual manifestation of leptospirosis. This suggestion should not be overlooked when analyzing the causes for bilateral facial palsy, and should be considered with other possible differential diagnoses, some of which are potentially fatal.

    Full Text Available Abstract Thymic large cell neuroendocrine carcinomas (LCNECs are very rare. We here describe a case in which the tumor could be completely resected. A 55-year-old male was admitted to our hospital for treatment of an anterior mediastinal tumor found at a regular health check-up. The patient underwent an extended thymectomy of an invasive thymoma of Masaoka's stage II that had been suspected preoperatively. The tumor was located in the right lobe of the thymus and was completely resected. Final pathological diagnosis of the surgical specimen was thymic LCNEC. The patient underwent adjuvant chemotherapy with irinotecan and cisplatin in accordance with the diagnosis of a lung LCNEC, and is alive without recurrence or metastasis 16 months after surgery.

    2006-01-01

    BACKGROUND: Nasopharyngeal carcinoma (NPC) has a propensity to develop distant metastases at a high rate and with poor prognosis. Metastatic sites are usually multifocal and involve bones, lungs, liver and distant lymph nodes. Management of metastatic disease is essentially palliative and is based on chemotherapy. METHODS:A 50-year-old man with a solitary liver metastasis from a newly diagnosed NPC was treated by segmentectomy. Prior to surgery, neoadjuvant chemo-therapy followed by concurrent chemoradiotherapy was administered. RESULTS:Complete remission of the primary disease was achieved, although the size of the hepatic lesion was increased. After resection of the liver metastasis, no signs of local or distant recurrence was noted during the 6-month follow up. CONCLUSION:Although surgical treatment has a limited role in metastatic NPC, there are rare cases of localized disease with a reasonable outcome after resection.

    2012-01-01

    Full Text Available This study examined the effect of surgeons’ volume on outcomes in lung surgery: lobectomies and wedge resections. Additionally, the effect of video-assisted thoracoscopic surgery (VATS on cost, utilization, and adverse events was analyzed. The Premier Hospital Database was the data source for this analysis. Eligible patients were those of any age undergoing lobectomy or wedge resection using VATS for cancer treatment. Volume was represented by the aggregate experience level of the surgeon in a six-month window before each surgery. A positive volume-outcome relationship was found with some notable features. The relationship is stronger for cost and utilization outcomes than for adverse events; for thoracic surgeons as opposed to other surgeons; for VATS lobectomies rather than VATS wedge resections. While there was a reduction in cost and resource utilization with greater experience in VATS, these outcomes were not associated with greater experience in open procedures.

    Full Text Available Primary mucoepidermoid tumors of the lung are rare entities. Synchronous primary malignancies of the lung involving mucoepidermoid carcinoma and mucinous adenocarcinoma are even rarer and constitute a unique set of patient population. The presentation, diagnosis and treatment strategies for this patient population are not well described. In most cases, the diagnosis of synchronous primary lung malignancy is made after pathological examination of the resected lung specimen. Molecular and genetic analysis is now being used to supplement the diagnosis of synchronous primary lung malignancies. In this work, we briefly discuss the current state of knowledge of this unique combination of primary lung malignancies and describe the clinical presentation and management of a patient with a rare combination of synchronous primary lung malignancies.

  18. Surgery for nonsmall cell lung cancer

    Loïc Lang-Lazdunski

    2013-09-01

    Full Text Available Surgery remains the best curative option in patients with early stage lung cancer (stage I and II. Developments in minimally invasive techniques now allow surgeons to perform lung resections on elderly patients, patients with poor pulmonary function or significant cardiopulmonary comorbidities. New techniques, such as stereotactic radiotherapy and ablative procedures, are being evaluated in early-stage lung cancer and may represent an alternative to surgery in patients unfit for lung resection. Perioperative mortality rates have dropped significantly at most institutions in the past two decades and complications are managed more efficiently. Progress in imaging and staging techniques have helped cut futile thoracotomy rates and offer patients the most adequate treatment options. Large randomised trials have helped clarify the role of neoadjuvant, induction and adjuvant chemotherapy, as well as radiotherapy. Surgery remains an essential step in the multimodality therapy of selected patients with advanced-stage lung cancer (stage III and IV. Interventional and endoscopic techniques have reduced the role of surgery in the diagnosis and staging of nonsmall cell lung cancer, but surgery remains an important tool in the palliation of advanced-stage lung cancer. Large national/international surgical databases have been developed and predictive risk-models for surgical mortality/morbidity published by learned surgical societies. Nonetheless, lung cancer overall survival rates remain deceptively low and it is hoped that early detection/screening, better understanding of tumour biology and development of biomarkers, and development of efficient targeted therapies will help improve the prognosis of lung cancer patients in the next decade.

  19. Proximal Gastrojejunal Reconstruction after Pancreaticoduodenal Resection

    Directory of Open Access Journals (Sweden)

    M. Wayne

    2012-01-01

    Full Text Available Introduction. Reconstruction by proximal gastrojejunostomy, and distal biliary and pancreatic anastomoses is infrequently used after resection of the head of the pancreas because of fear of fistulas and cholangitis. Pancreaticoduodenectomy is being performed more frequently for cystic malignant and premalignant lesions. Because of this there is a need for endoscopic visualization and biopsy of the residual pancreatic duct, since multi-centricity is characteristic of some of these malignancies. Since endoscopic access of the bile duct and pancreatic duct is difficult and unsuccessful in 50–70% after B II or Roux Y reconstruction, we prospectively studied the merit and complications (early and late of proximal gastrojejunal (PGJ reconstruction after pancreaticoduodenal resection. Material and Methods. Thirty nine consecutive, non-radomized patients underwent pancreaticoduodenectomy and PGJ reconstruction over 14 mos. There were 21 males and 18 females. Results. 7 patients with IPMN have undergone repeat CT scanning for surveillance, with 3 requiring repeat EUS and ERCP. There were no technical difficulties accessing the pancreas or the pancreatic duct, supporting the PGJ reconstruction. Conclusion. Proximal gastrojejunal reconstruction following pancreaticoduodenal resection may be safely done with similar morbidity to traditional pancreaticojejunal reconstructions. PGJ reconstruction may be of greater value when direct visual access to the bile duct or pancreatic duct is necessary, and should be considered when doing resection for mucinous cysts or IPMN of the head of the pancreas.

    Full Text Available BACKGROUND: Prolonged air leak (longer than three days was hypothesized to be the primary cause of extended hospital stays following pulmonary resection. Its effect on length of stay (LOS was compared with that of suboptimal pain control, nausea and vomiting, and other causes. Predictors of prolonged LOS and of prolonged air leaks were investigated.
