    ABSTRACT: Background Atypical carcinoids (AC) of the lung are rare intermediate-grade neuroendocrine neoplasms. Prognostic factors for these tumours are undefined. Methods Our cooperative group retrieved data on 127 patients operated between 1980 and 2009 because of an AC. Several clinical and pathological features were studied. Results In a univariable analysis, T-status (p=0.005), N-status (p=0.021), preoperative M-status (previously treated) (p=0.04), and distant recurrence developed during the outcome (p<0.001) presented statistically significant differences related to survival of these patients. In a multivariable analysis, only distant recurrence was demonstrated to be an independent risk factor for survival (p<0.001; HR: 13.1). During the monitoring, 25.2% of the patients presented some kind of recurrence. When we studied recurrence factors in a univariable manner, sublobar resections presented significant relationship with locoregional recurrence (p<0.001). In the case of distant recurrence, T and N status presented significant differences. Patients with preoperative M1 status presented higher frequencies of locoregional and distant recurrence (p=0.004 and p<0.001, respectively). In a multivariable analysis, sublobar resection was an independent prognostic factor to predict locoregional recurrence (p=0.002; HR: 18.1). Conclusions Complete standard surgical resection with radical lymphadenectomy is essential for AC. Sublobar resections are related to locoregional recurrence, so they should be avoided except for carefully selected patients. Nodal status is an important prognostic factor to predict survival and recurrence. Distant recurrence is related to poor outcome.

    ABSTRACT: Chest wall tumors are unfrequent. With the aim of present our results obtained in the treatment of malignant chest wall tumors, we present our cases surgically treated between 1992 and 2009. The series is formed by 35 cases (23 males), with a mean age of 55 (ranges 21-82). The presentation was with symptoms of 8,9 month of average duration in 30 cases. Diagnosis was based in imaging test (chest radiography 100%, computed tomography 85,7%, bone scintigraphy 20,1%, ultrasonography 17,1%, magnetic resonance 14,3%) and tumor biopsy (transthoracic punction 37,1%, incisional biopsy 5,7% and excisional biopsy in 62,9% previous to complete surgical resection). Surgical treatment was complete excision with margin free tumor of 3-5 cm when it was possible and chest wall reconstruction with mesh and myoplastia. Survival analysis was made evaluating age, sex, tumor size and grade. There were affected margins in 2 cases (5,7%). Adjuvant treatment was used in 11 patients (5 chemotherapy, 6 radiotherapy). Postoperative complications were present in 6 cases (17,3%). There was not mortality. Local relapses were present in 6 patients (17,3%) and metastases in 7 (20%). Survival was not related with the tumor grade. We conclude that surgical treatment of malignant chest wall tumors has not mortality in our experience. Postoperative morbidity is low. Survival is not related to tumor grade if enough free tumor margins is obtained.

    ABSTRACT: Though spontaneous pneumothorax (SP) is a well-known complication of pulmonary tuberculosis (TB), there are very few reports addressing this topic. For this reason, we retrospectively analysed the experience of SP in patients diagnosed with TB in our hospital between 1989 and 2010. Out of 872 patients treated for SP during this period, 47 (5.4%) had TB antecedents, 21 with active TB (0.95% of the 2,089 TB cases diagnosed during this period) and 26 with residual inactive TB. 46 cases were treated with pleural drainage (PD): 40 (85%) with only one PD, two with two, and four with three. The mean ± SD length of PD treatment was 12.9 ± 11.3 days. In 11 (23%) cases, a relapse of SP occurred, with no statistical relationship between the different studied variables. In 13 (28%) cases, it became necessary to carry out a resection (atypical segmentectomy in all cases) for persistent air leaks with PD. Survival statistics were unfavourable only in elderly patients and those infected with HIV. We conclude that the treatment of SP secondary to TB with PD is usually a sound response, with a good general prognosis and a low percentage of cases that require another PD and surgical treatment.

    ABSTRACT: Primary pleural leiomyoma is extremely rare and has only been described a few times. We present a case of a young woman with right pleuritic pain. A computed tomography confirmed the existence of a solid right pleural tumor which had compressed and displaced the lung, mediastinum and heart. Percutaneous biopsy showed a 'proliferation of smooth muscle cells without evidence of malignancy'. Surgical excision was done and the tumor was not associated to vascular, broncho-pulmonary or mediastinal structures. The definitive diagnosis was primary pleural leiomyoma. Primary pleural leiomyoma should be included in a differential diagnosis of pleural tumors and suspected in asymptomatic patients with radiologically-apparent benign tumors and the presence of smooth muscle fibers in the biopsy. Complete resection and follow-up is advised because it can grow very large and has malignant potential.

    ABSTRACT: Thoracic sympathectomy (TS) is the treatment of choice for severe primary hyperhidrosis. However, complications, side effects and satisfaction have not been well defined. To analyze the complications, side effects, satisfaction degree and quality of life of patients after TS for primary upper limb hyperhidrosis. One-year follow-up after 406 consecutive TS for primary upper limb hyperhidrosis. Bilateral TS was completed in all patients. Complications arose in 23 cases (5.6%), with pneumothorax being the most frequent. The success rate after discharge, 6 and 12 months was respectively, 100%, 98.1% and 96.5% for palmo-axillary hyperhidrosis; 100%, 99.3% and 97.8% for isolated palmar hyperhidrosis and 100%, 85.7% and 71.4% for isolated axillary hyperhidrosis. No persistence of hyperhidrosis was observed. Global recurrence was 3.7% (28.5% axillary hyperhidrosis group). Compensatory sweating (CS) appeared in 55% and was not related to the extension of the TS. Being female was a predisposing factor of CS (p<0.004). Excessive dryness appeared at 9% and was associated with extensive TS (P<0.001). Plantar hyperhidrosis improved at 33.6%, worsened at 10% and remained stable during the follow-up. Satisfaction degree decreased with the passage of time and was associated with recurrence. Quality of life was excellent at discharge, 6 and 12 month in 100%, 100% and 97%, respectively. Pneumothorax is the most frequent complication of TS. CS is the main and undesirable side effect, appears with the passage of time, and is not related to the extension of TS. Being female is the only predictor factor of suffering CS. Plantar hyperhidrosis improves initially, although tends to reappear. Excessive dryness appears in extensive TS and does not improve over time. Postoperative satisfaction degree is high but decreases over time owing to the appearance of recurrence. Effectiveness and the absence of CS determine an excellent quality of life. Six percent of the patients regret the surgery because of severe CS. Informing patients of possible side effects before TS is essential.

    ABSTRACT: We undertook a review of patients with chest trauma attended between January 1992 and June 2005 in order to establish severity criteria in these cases. During the study period, 1,772 cases (1,346 [76%] males) were treated, with ages ranging from 7 to 98 years (mean, 46.4 years). The Revised Trauma Score (RTS) was calculated and the following variables were also studied as potential indicators of severity: age, extent of the injury, number of rib fractures, presence of lung contusion, hemothorax, cardiorespiratory repercussions, and need for mechanical ventilation. At the time of admission, 84.4% of patients presented only symptoms related to the injury, with no general repercussions, and 66.7% had an RTS of 12. The number of rib fractures was a reliable indicator of severity, as was the presence of multiple injuries, lung contusion, need for mechanical ventilation, and cardiorespiratory repercussions. Neither age nor presence of hemothorax was found to be an indicator of severity. Pleural drainage was performed in 756 cases and was effective in 670 (88.6%). There are a number of indicators of severity in chest trauma, related more closely to the type and repercussions of the trauma than to the age of the patient. There is a high incidence of fluid or gas accumulation in the pleural space, though this can be easily managed by pleural drainage, which constitutes the main therapeutic procedure in chest trauma.

    ABSTRACT: Soft tissue tumors of the chest wall are rare. Between 1998 and 2007 we treated eight cases of elastofibroma of the thoracic wall, an infrequent primary tumor of the chest. Seven females and one male between 44 and 62 years presented with dorsal subscapular tumors of months and even years of evolution. One case was a relapse from previous interventions and in three cases the tumor was bilateral. A surgical excision was performed in all cases, confirming the source of the tumor. There were no postoperative complications or relapses. We concluded that elastofibroma is a tumor that appears most frequently in middle aged women, and that diagnosis can be established through the use of imaging and fine needle aspiration biopsy. Given its benign character and slow growth, in cases where it is asymptomatic, its evolution can be controlled without surgical intervention.

    ABSTRACT: It has been hypothesized that medical procedures performed in high-volume units carry less risk and achieve a better outcome. To determine the relationship between the number of interventions and the operative morbidity, mortality and long-term survival in the surgery of bronchogenic carcinoma (BC). Prospective, multicenter Spanish study was conducted in 19 departments of thoracic surgery on 2994 patients operated on consecutively with the aim of curing BC. The thoracic surgery departments have been classified into three groups, according to the number of interventions performed per year: I (1-43 cases/year; centers=7; n=565; 18.9%), II (44-54 cases/year; centers=6; n=1044; 34.9%) and III (55 or more cases/year; centers=6; n=1385; 46.3%). When the three groups were compared, the frequency of complete surgery was found to be 84% for group I, 76% for group II and 83% for group III (p=0.001, for comparisons between groups I/II and II/III). The pathological stages were identical in the three groups. The overall morbidity and the mortality in all patients or above the age of 75 or in pneumonectomies were not different among the groups. When considering all the patients with prognostic information (n=2758), no differences were found regarding the 5-year survival among the groups. When only patients in postoperative stage I-II and complete resection were evaluated, excluding operative mortality (n=1128), 5-year survival was 0.58 for group I, 0.57 for group II and 0.50 for group III (p=0.06 between groups II and III; p=0.08 between groups I and III). No significant differences that do not favor the hypothesis that there is increased surgical risk and worse survival in centers having a lower volume were found in this Spanish multicenter study.

    ABSTRACT: Spontaneous pneumomediastinum (SP) is a rare disorder. The objective of this study is to examine a series of patients treated during 19 years, analyzing risk, clinical, and diagnostic factors as well as treatment and long-term follow-up. A descriptive, retrospective study was done from 1984 to 2003 on 32 patients admitted to the hospital with SP. The average age was 21.4+/-6.1 years, 24 (75%) males. 34.4% had developed some strain before arriving at the hospital. Nine of the cases were asthmatic (28.1%) and another nine were smokers (28.1%). The most frequent complaint was thoracic pain, 25 (78.1%). In the physical examination, subcutaneous cervical emphysema was observed in 25 patients (78.1%). A simple X-ray of the thorax was used in the diagnosis of 32 cases. In two patients, radiological signs of pneumothorax were discovered. An esophagogram was done on two patients but there were no significant findings. All of the cases were treated conservatively. The average hospital stay was 3.2+/-1.6 days. No relapses were noted in the follow-ups. SP is an entity that evolves correctly without treatment and has no long-term relapses. Once other occasionally associated entities are ruled out, outpatient management can be employed.

    ABSTRACT: objective: To evaluate the current staging system of lung cancer, taking into account different selection criteria for the studied population. Population: A total of 2,991 consecutive patients with surgical lung cancer were prospectively compiled from 19 Spanish hospitals (Bronchogenic Carcinoma. Cooperative Group of the Spanish Society of Pneumology and Thoracic Surgery) between 1993 and 1997. Methods: The Kaplan-Meier method was used to calculate survival at 5 years (S5) for each pathologic stage, and the log-rank test was used for comparison purposes. These studies were performed in the total group (population 1, n = 2,972); excluding operative mortality and small cell lung cancer cases (population 2, n = 2,697); excluding cases with induction therapy (population 3, n = 2,542); excluding cases with exploratory thoracotomy (population 4, n = 2,304); and, lastly, excluding cases with incomplete resection (population 5, n = 2082) [70% of the initial population]. Results: The global S5 was similar in populations 1, 2, and 3: 34% (95% confidence interval [CI] 32 to 36%), 37% (95% CI, 35 to 39%), and 38% (95% CI, 35 to 39%), but different from that of populations 4 and 5: 40% (95% CI, 39 to 43%) and 43% (41 to 45%), respectively. For pathologic stage 1, pathologic stage 11, and pathologic state IIIA (pIIIA), S5 was similar in the five reported populations. In pathologic stage IIIB (pIIIB), there were differences in S5 between populations 1, 2, and 3 (13 to 15%; 95% CI, 10 to 19%) and populations 4 and 5 (26 to 29%; 95% CI, 19 to 38%). In population 4, there was no significant prognostic difference between two specific stage groups, that is between pathologic stage IB (pIB) and pathologic state IIA (pIIA) [p = 0.70] and between pIIIA and pIIIB (p = 0.79); the pathologic T3N2M0 combination has a S5 (13%) lower than that for pIIIB (26%). Conclusion: The definition of the population that constitutes the denominator for the analysis of survival in surgical lung cancer is important in pIIIB. The inclusion or exclusion of cases without resection is the most important factor for the selection of such population. This study detected that there are no prognostic differences between pIB and pIIA, and between pIIIA and pIIIB.

    ABSTRACT: Thymolipoma is an uncommon benign tumor (accounting for 2% to 9% of thymus tumors). We present the case of a 26-year-old man who sought medical attention for left-sided pleural pain of 3 months duration. Computed tomography showed a mass in the left side of the chest occupying both the anterior mediastinum and the left pleural cavity. This mass caused lung collapse and mediastinal shift. Magnetic resonance imaging revealed a large fatty tumor and transthoracic biopsy with radiological guidance confirmed the diagnosis. The tumor was resected through a left thoracotomy. No postsurgical complications occurred and the histopathological diagnosis was thymolipoma.
