The changes in lung function were prospectively studied for patients with lung carcinoma who were treated with relatively high doses of irradiation. Their dyspnoea score, lung volume spirometry, diffusion capacity and ipsilateral hemithorax perfusion were measured at presentation, again between 5 and 6 months after irradiation (Group 1, 36 evaluable patients), and once more between 11 and 12 months (Group 2, 16 evaluable patients). There was a worsening of the dyspnoea score from 1 to 2, in a large percentage of patients, but only 6% developed a dyspnoea score of 3. The largest change in lung function tests was a decrease in the diffusion capacity (DLCO) to 14% at 6 months and 12% at 12 months (statistically significant, P < 0.0001 paired t-test). The forced vital capacity (FVC) and the total lung capacity (TLC) showed a lesser decrease at 6 and 12 months, and the smallest decrease, which was not statistically significant, was in the forced expiratory volume in 1 s (FEV1). There was also a statistically significant decrease in the ipsilateral hemithorax lung perfusion of 16% at 6 months and 20% at 12 months. There was a weak correlation between the decrease in the DLCO and the FEV1 at follow-up. There was no statistically significant correlation between initial perfusion or decreased perfusion and the decrease in lung function. Lung irradiation should be regarded as an ablative form of therapy, analogous to surgery, in patients with a projected survival of 6 months or more. The DLCO is the most sensitive indicator of clinical damage and its pretreatment assessment should be useful in predicting clinical tolerance to irradiation.

We describe a patient with recurrent respiratory papillomatosis (RRP) associated with human papilloma virus (HPV), who developed a fatal squamous cell carcinoma of the lung. At the age of 1 year he presented with hoarseness, dyspnoea and inspiratory stridor but the diagnosis of RRP was made only 1 year later. At the age of 4 years he was tracheostomized because of upper airway obstruction. In spite of multiple surgical excisions and topic treatment with 5-fluorouracil the papillomata extended to the lung parenchyma. At the age of 16 years he developed a squamous-cell carcinoma of the lung and died 4 months later. Transformation to pulmonary carcinoma is a rare complication in non-irradiated patients with lung papillomatosis. We found only 11 similar cases in the literature.

Thirty-eight horses with confirmed thoracic neoplasia included 28 (37.7%) with lymphosarcoma, 4 (10.5%) with metastatic renal cell carcinoma, 2 (5.3%) with primary lung carcinoma, 2 (5.3%) with secondary squamous cell carcinoma from the stomach, 1 (2.6%) with pleural mesothelioma, and 1 (2.6%) with malignant melanoma. The major clinical features included weight loss, inappetence, dyspnoea and coughing, but in cases of lung metastases, they related more to the primary site of tumour formation. Haematological and serum biochemical abnormalities were non-specific. Specific pre-mortem diagnosis was made in 14 horses; this was most readily achieved when exfoliated neoplastic cells were present in pleural fluid.

To clarify clinical significance of symptoms presented at the beginning of treatment, we analyzed the symptoms in 240 patients with non-small cell lung cancer treated with definitive radiation therapy. Symptoms were classified into four groups: no symptom (Grade 0), cough, sputum/hemosputum and fever up (Grade 1), chest pain and breathlessness (Grade 2), appetite loss, body weight loss, SVC syndrome, hoarseness, and pain in the upper limb/shoulder (superior sulcus tumor) (Grade 3), and their therapeutic outcomes were examined. The 2- and 5-year overall actuarial survival rates for patients with squamous cell carcinoma were 38.5% and 15.4% for Grade 0, 40.5% and 20.1% for Grade 1, 17.9% and 2.6% for Grade 2, and 15.8% and 5.3% for Grade 3. A statistical difference was noted in survival between Grades 0-1 and Grades 2-3 (P < 0.01), but was not seen between Grades 0 and 1, or between Grades 2 and 3. As for patients with stage III disease alone, the difference in survival was still significant between Grades 0-1 and 2-3 (P < 0.05). In patients with adenocarcinoma/large cell carcinoma, however, no obvious relationship was found between symptoms and prognosis, except for body weight/appetite loss. In conclusion, though the symptoms closely related to clinical stage and performance status and not an independent prognostic factor, chest pain and breathlessness correlated with poor therapeutic outcome as well as body weight loss and T3-4 related symptoms, while cough, sputum (hemosputum), and fever were favorable symptoms in patients with squamous cell carcinoma who received definitive radiation therapy.

A retrospective study was performed in patients diagnosed with primary lung cancer, and admitted to the Instituto Nacional de Enfermedades Respiratorias between 1984 to 1992. One thousand and nineteen patients were studied, 636 males and 383 females. We found a higher incidence in the group among 61-70 years of age in both sexes. The highest percentage of tumors were from the adenocarcinoma variety, followed by the epidermoid carcinoma, while the small-cell carcinoma presented a lower incidence. Smoking has been associated with the development of lung cancer. Many of our patients were smokers. The highest frequency was in smokers with a smoking habit of more than 30 years and a rate of more than 10 cigarettes per day. However, an important part of the patients with cancer did not have a smoking habit, which led us to believe that there are other etiological possibility factors (genetic or environmental) that could be involved. Most of the cases of cancer were staged as stage IIIb and stage IV and the patients had an ECOG of 1-2. The main symptoms were coughing, sputum, dyspnea and thoracic pain. This data shows an increasing frequency of lung cancer in Mexico city as well as other countries, it also shows that it is going to be a serious health problem in the future. We consider that in order to improve the prognosis, it is necessary to increase the educational and orientation campaigns among the adult population with or without a smoking history.

Endobronchial therapy is commonly used in the palliative management of malignant disease, but the optimal combinations of treatment modalities (laser, brachytherapy, external beam radiotherapy) have not been defined. We have undertaken a prospective analysis of symptom response, duration of response, and prognostic factors for 117 patients treated with brachytherapy at a single centre, to identify hypotheses suitable for prospective randomised studies. All but one patient had received previous treatment. The percentage of patients with scores of 0 or 1 (none or mild) for each symptom pre-treatment and at 3 months were as follows: cough 62% to 77% (43% improving by at least one grade, N.S.); dyspnoea 32% to 56% (50% improvement by at least one grade, P = 0.0063); haemoptysis 78% to 97%; performance status 65% to 84% (54% by at least one grade, P = 0.0417). An actuarial risk of fatal haemoptysis at 2 years of 20% was associated with prior laser resection (P = 0.048). Death before 2 months was associated with dyspnoea scores of 3 or 4. Suggestions for randomised studies are made to address some of the uncertainties revealed by the analysis.

More than 30% of lung cancers arise in patients aged 70 years or more; however, because elderly patients are not considered to tolerate chemotherapy, they are generally excluded from clinical trials and are not considered eligible for aggressive cisplatin-based chemotherapy in clinical practice. The aims of the present study were to test tolerability and activity of weekly vinorelbine in advanced non-small cell lung cancer (NSCLC) patients aged 70 years or more, and to define whether minimum conditions existed for a randomised comparison with best supportive care. The study was designed as a multicentre two-stage phase II trial according to Simon's optimal design: 8 or more responses out of 43 treated patients were expected at the end of the trial. Patients aged 70 years or more were eligible if they had a cytological or histological diagnosis of NSCLC at stage IIIb-IV and a performance status less than or equal to two according to the ECOG scale. Vinorelbine was given intravenously (i.v.) at a dose of 30 mg/m2 every week for 12 doses. As planned, 43 patients entered the study; median age was 73 years (range 70-80); 11 patients were older than 75 years. Median dose-intensity (mg/m2/week) of vinorelbine was 21.2 (range 7.5-30) and was not affected by age of patients. Toxicity was generally mild, mainly haematological and never life-threatening. ECOG performance status improved in 26% of patients; cough and pain improved in more than 40% of patients symptomatic at entry, while dyspnoea improved in 28%; approximately half the patients had a stabilisation of their symptoms. 10 patients (23-95% exact confidence interval (CI): 12-39%) obtained a partial response. Median time to progression was 11 weeks (95% CI 8-30) and median survival 36 weeks (95% CI 28-53). One-year estimated progression-free and overall survival rates are 16% and 36%, respectively. In conclusion, vinorelbine was well tolerated and active in the treatment of elderly NSCLC patients. A phase III trial (ELVIS-Elderly Lung Cancer Vinorelbine Italian Study) comparing best supportive care versus best supportive care plus vinorelbine is now ongoing.

The essential characteristic on carcinoma of the lung are presented. With 100 patients with Ca bronche diagnosed by pathology, we evaluated the significance of the clinical manifestation of this disease. The most frequent symptoms are: cough (83%), pectoral pain (65%), dyspnoea (60%), temperature (57%), haemoptysis (29%). It is presented the etiopathogenesis of these symptoms. The significance of history and physical findings in forming a preliminary diagnosis is analysed. This in turn is the basis for the programming examinations and diagnostic procedures.

The efficacy and toxicity profile of gemcitabine was evaluated in this phase II study of chemonaive patients with locally advanced and metastatic non-small cell lung cancer (NSCLC). Eighty patients (62 males, 18 females) were entered into this study. The disease stage was IIIA in ten patients, IIIB in 32, and IV in 38 patients. The median age was 61 (range 41 - 78). Karnofsky performance status was > or = 80 in 88% of patients. All patients were chemonaive, but five patients had received prior radiotherapy and 34 patients had undergone prior surgery. Gemcitabine 1250 mg/m2 was given as a 30-min intravenous infusion on days 1, 8, and 15 of a 28-day cycle. Patients received up to nine cycles (median three cycles). Of 872 doses 815 (93%) were administered without dose delay or modification. Of the 80 patients enrolled, 76 were evaluable for efficacy analysis, and 16 patients had a partial response for an overall response rate of 21.1% (95% CI, 11.9-30.3%). A further 47 patients (61.8%) had stable disease. Partial responses were seen in eight of 41 stage III patients (19.5%) and in eight of 35 stage IV patients (22.9%). The median time to progressive disease was 4.6 months. Median survival for all 80 patients was 7.1 months. Haematological toxicity was mild with grade 3 4 neutropenia in 6.3% of patients, grade 3 thrombocytopenia in 3.8% of patients, and grade 3 anaemia in 2.5% of patients. Grade 3 non-laboratory toxicity was: somnolence (1.3% of patients), infection (1.3%), nausea and vomiting (6.4%) and dyspnoea (5.1%). This study confirms that single-agent gemcitabine is active in advanced NSCLC and its well-tolerated safety profile makes it particularly suited to outpatient use.

Normative data and trends for a disease- and site-specific quality of life (QL) instrument for individuals with lung cancer, the Lung Cancer Symptom Scale (LCSS), are presented to facilitate the user's interpretation of test scores. Data for patients enrolled in two large, identical, randomized trials of a new combination chemotherapy regimen for patients with stages III and IV non-small-cell lung cancer (NSCLC) were combined into one dataset (n = 673). For these patients with a Karnofsky performance status (KPS) of 60-100%, QL had been prospectively measured at baseline, day 29 and every 6 weeks thereafter. Descriptive statistics for the LCSS are presented for three time points (baseline, day 29 and day 71) and for specific demographic and disease-related characteristics (age, gender, race, performance status and stage of disease) to provide expected values and their variability during chemotherapy. Data from a small dataset of 63 NSCLC inpatients with KPS scores of 20-50% are also presented for a comparison sample of supportive care for inpatients and hospice patients. For the 673 NSCLC patients at baseline there were no significant differences in QL by age, gender, or race. Major presenting lung cancer symptoms at baseline for this combined sample were dyspnea 87%, cough 86%, pain 81%, loss of appetite 75%, and hemoptysis 41%. Of these patients, 81% had three or more presenting symptoms at baseline (2% had no symptoms; 5%, one symptom; 12%, two symptoms; 18%, three symptoms; 27%, four symptoms; and 36%, five symptoms). The mean LCSS baseline score (best = 0; worst = 100) was 26.56 (SD 16.10). The mean scores for day 29 and day 71 were 25.46 (SD 16.52) and 25.30 (SD 16.93), respectively, but follow-up assessments on progressers were not obtained. Stage III patients had a mean LCSS score of 23.7 (SD 15.1), whereas stage IV patients reported a mean LCSS score of 27.3 (SD 16.3). The mean LCSS score for the group with KPS 60-70% was 34.8 (SD 15.5), and that for the group with KPS 80-100% was 23.3 (SD 15.1). The mean LCSS score for the lower performance group, with KPS scores of 20-50% at baseline, was 46.85 (SD 17.65).
