The most recent guidelines define COPD in a multidimensional way, nevertheless the diagnosis is still linked to the limitation of airflow, usually measured by the reduction in the FEV1/FVC ratio below 70%. However, the severity of obstruction is not directly correlated to symptoms or to invalidity determined by COPD. Thus, besides respiratory function, COPD should be evaluated based on symptoms, frequency and severity of exacerbations, patient’s functional status and health related quality of life (HRQoL). Therapy is mainly aimed at increasing exercise tolerance and reducing dyspnea, with improvement of daily activities and HRQoL. This can be accomplished by a drug-induced reduction of pulmonary hyperinflation and exacerbations frequency and severity. All guidelines recommend bronchodilators as baseline therapy for all stages of COPD, and long-acting inhaled bronchodilators, both beta-2 agonist (LABA) and antimuscarinic (LAMA) drugs, are the most effective in regular treatment in the clinically stable phase. The effectiveness of bronchodilators should be evaluated in terms of functional (relief of bronchial obstruction and pulmonary hyperinflation), symptomatic (exercise tolerance and HRQoL), and clinical improvement (reduction in number or severity of exacerbations), while the absence of a spirometric response is not a reason for interrupting treatment, if there is subjective improvement in symptoms. Because LABA and LAMA act via different mechanisms of action, when administered in combination they can exert additional effects, thus optimizing (i.e. maximizing) sustained bronchodilation in COPD patients with severe airflow limitation, who cannot benefit (or can get only partial benefit) by therapy with a single bronchodilator. Recently, a fixed combination of ultra LABA/LAMA (indacaterol/glycopyrronium) has shown that it is possible to get a stable and persistent bronchodilation, which can help in avoiding undesirable fluctuations of bronchial calibre.
From January 1975 to April 1987, 27 patients underwent surgical resection of non oat cell lung cancer and a single brain metastasis. There were 25 men and 2 women ranging in age from 37 to 70 years. In 21 cases the brain metastasis was synchronous while in 6 cases the onset was metachronous. In 17 cases, the site of the brain metastasis was supratentorial and in 10 cases it was located in the posterior fossa. The chest X-ray confirmed the primary lung tumour in 24 cases. In 3 cases, only bronchoscopy and cytology revealed the primary focus of the tumour. The lung cancer was located in the upper lobe in 25 patients. Upper lobectomy was performed in 23 patients, pneumonectomy in 3, and lower lobectomy in 1. There were no operative deaths. The cell type was adenocarcinoma in 19 cases, squamous cell carcinoma in 4 patients and large cell carcinoma in 4. Only the tumour and nodes were used for staging at thoracotomy. The classification was: 12 patients in stage I, 2 in stage II, and 13 in stage III. At conclusion of the study the longest survival was 68 months after thoracotomy. There was no significant difference in the duration of survival in patients over or under 50 years old. Better results were obtained in patients without node metastases at thoracotomy (median survival of 30 months and an overall 5-year survival of 35%), and in patients with supratentorial metastases (median survival of 22 months and an overall 5-year survival of 23.4%). Our experience confirms that combined surgery prolongs survival and improves the quality of life.
