Primary angiosarcoma of the chest wall.

We report the case of a 15-year-old boy with primary high grade angiosarcoma of the 6th rib. The patient underwent chest wall resection (3 ribs) and reconstruction by using a sandwich of Marlex mesh with strips of methyl methacrylate. No adjuvant treatment was administered. A favourable outcome was observed, with no recurrence at 6-year follow-up. Functional results were excellent as well, with complete return of the patient to normal activities.

Surgical treatment of stage I lung cancer. Results and prognostic factors.

BACKGROUND: The aims of the present study were: 1) to study the type and extent of resection in patients with pathological stage I lung cancer; 2) to evaluate the results of surgical treatment; 3) to assess prognostic factors. SETTING: a tertiary referral general hospital. METHODS: Retrospective review of clinical records of 296 patients operated on for pathologic stage I lung cancer between 1989 and 1998. Mean follow-up period was 33.1+/-28.1 months. Survivals were calculated by the actuarial method and compared by the long-rank test. Age, sex, tumor size, type and extent of resection and histologic type were evaluated by univariate and multivariate analisis. RESULTS: Two hundred and forty-five lobectomies, 39 pneumonectomies, 5 segmental resections and 7 wedge resections were performed. Overall actuarial 5- and 10-year survivals were 62 and 49%, respectively. Stage Ia patients showed significantly better 5- and 10-year survivals (76 and 54%, respectively) as compared to Stage Ib patients (57 and 46%, p=0.007). Univariate analysis showed no significant difference in survival according to the age, the sex or the extent of resection. The histological type influenced the outcome (p=0.05): 5-year survival rate were 57, 67, 75% in squamous cell carcinoma, adenocarcinoma and bronchoalveolar carcinoma, respectively. At multivariate analysis stage and histology were identified as independent prognostic factors. CONCLUSIONS: Satisfactory results in terms of suvival can be achieved following surgery for stage I lung cancer. The T status and the histologic type significantly influence survival.

Surgical treatment of lung cancer invading the chest wall: results and prognostic factors.

BACKGROUND: The study was performed to assess prognostic factors in patients with lung cancer invading the chest wall treated by surgery. METHODS: We reviewed retrospectively clinical records of all patients operated on for lung cancer invading chest wall structures between 1984 and 1998. RESULTS: Two hundred one patients were operated on in this 14-year period. One hundred thirty-seven lobectomies, 55 pneumonectomies, and 9 wedge resections were performed. Extrapleural resection (when invasion was limited to the parietal pleura) and chest wall resection (in the case of invasion of deeper structures) were combined with pulmonary resection in 79 (39%) and 122 (61%) cases, respectively. Pathologic TNM stages were T3N0 in 116 (57.5%) cases, T3N1 in 52 (26%), T3N2 in 27 (13.5%), and T4N0-N1 in 6 (3%). A complete resection was achieved in 167 (83%) cases. Fourteen postoperative deaths (7%) occurred. One hundred thirty-nine patients (74%) underwent postoperative radiotherapy. Actuarial 5-year survival was 24% and 13% after complete and incomplete resection, respectively (p < 0.05). Actuarial 5-year survival after complete resection was 25% in T3N0 patients, 20% in T3N1, and 21% in T3N2. In completely resected patients, univariate and multivariate analyses identified three independent prognostic factors: nodal involvement, depth of parietal invasion, and age. Radiation therapy did not improve survival if a complete resection was possible. CONCLUSIONS: Completeness of resection, nodal involvement, depth of invasion, and age affect survival of patients with lung cancer invading the chest wall. N2 disease should not be considered a contraindication to surgery.

Recurrence of thymoma: analysis of clinicopathologic features, treatment, and outcome.

OBJECTIVE AND METHODS: This study reports clinicopathologic features, treatment, and outcome of 30 recurrent thymomas out of 266 totally resected thymomas. RESULTS: The mean disease-free interval to recurrence was 86 months. Recurrence occurred less frequently and after a longer disease-free interval after resection of encapsulated versus invasive thymomas. The presence of associated myasthenia gravis did not affect recurrence proportion, disease-free interval, or survival after recurrence. A local recurrence occurred in 11 patients, 17 patients had a distant recurrence, and the extent of the recurrence could not be determined in 2 cases. Surgical treatment of the recurrent tumor was attempted in 16 cases, and a total resection was possible in 10 cases; exclusive radiotherapy was done in 11 cases. Overall 5- and 10-year survivals were 48% and 24%, respectively. In a univariate analysis, survival was significantly better in the presence of a local recurrence and in case of a total resection of the recurrent tumor. The use of adjuvant therapy after the resection of the initial thymoma had no effect on reducing the incidence of recurrence, in prolonging the disease-free interval, or in improving survival after the development of the recurrence. In a multivariate survival analysis, significant prognostic factors were the presence of a local recurrence and total resection of the recurrent tumor. CONCLUSIONS: Surgical resection is recommended in patients with recurrent thymoma. Local recurrence and total resection of the recurrent tumor are associated with excellent prognosis. A poor prognosis may be anticipated in the presence of distant recurrence and when radical surgical treatment is not done.

Bronchial carcinoid associated with Cushing's syndrome.

Bronchial carcinoid is the most frequent cause of Cushing's syndrome due to ectopic ACTH production. The authors report a case of bronchial carcinoid which diagnosis was difficult because of the presence of pulmonary mycosis, that determined a hypercorticosuprarenalism. Medical treatment with octreotide, ketoconazolo and mitotane was useless, and bilateral suprarenalectomy was performed. A scintigraphy with raced somatostatin revealed a left lung area capting radiation. A CT scan of the thorax revealed a lesion of the lingula and the patient underwent an atypical lung resection with complete solution of the symptom. The problems of diagnosis and treatment of neuroendocrine tumors of the lung are discussed and the importance of SSA in the diagnostic procedure is pointed out.

[Mediastinal Castleman's disease].

Castleman's disease(CD) is an uncommon lymph node syndrome, generally located in mediastinum side, rarely systemic. Two histhologic types are described: the more common, termed the hyaline-vascular type, generally asymptomatic, and the second termed plasma cell type, with systemic manifestations of the disease, like fever, anemia and weight loss. The authors present a case of a young man with Castleman's disease, treated by prednisone without reduction of the adenopathy, and thus successfully operated, and discuss about aetiopathogenic theories and treatment of this disease.

[Benign fibrous mesothelioma of the pleura].

The authors report 4 cases of patients with benign fibrous mesothelioma of the pleura, an extremely rare pathology (not more than 500 cases reported to date in the literature), and discuss biological behaviour, diagnosis and surgical treatment. Benign fibrous mesothelioma is generally diagnosed by chance during chest x-ray given that it is paucisymptomatic; diagnostic procedures include thoracic CT (which may be supplemented by transthoracic needle biopsy) and bronchoscopy. Treatment is surgical and consists of exeresis of the neoplasia; prognosis is excellent and cases are reported in the literature of 24-year follow-up without recurrence. Lastly, the authors underline the importance of modern immunohistochemical techniques which help the surgeon to formulate a precise diagnosis and to differentiate benign fibrous mesothelioma.

[Spontaneous and traumatic pneumomediastinum. Analysis of 34 cases].

Pneumomediastinum (spontaneous, iatrogenic and traumatic) is a relatively uncommon infrequently reported entity. The most common cause is the rupture of marginal pulmonary alveoli, allowing bubbles of air to dissect along the vascular sheaths and connective tissue planes to the mediastinum. Rupture of the trachea or thoracic traumas are other causes of pneumomediastinum. The most common presenting complaint was retrosternal pain, dyspnea, dysphagia, weakness and neck pain. Physical finding revealed: subcutaneous emphysema extended to face, chest or neck, and Hamman's sign. Chest X-ray was made in all cases and diagnosis was completed with chest CT scan and tracheoscopy. We present our series of 34 PM between January 1.1993 to July 31.1995 and discuss about etiology, diagnosis and treatment of this entity.
