RESUMO

INTRODUCTION: The benefits of a rehabilitation program before surgical lung cancer resection remain to be defined. The purpose of this prospective observational study was to assess the effects of rehabilitation together with the use of noninvasive ventilation (NIV) in patients who were at a high operative risk. METHODS: Between January 2010 and June 2011, 20 consecutive patients (16 males, four females, mean age: 66 years [44-79]) with a clinical N0 non-small cell lung cancer were included. Eligibility criteria were predicted post-operative respiratory function (FEV1, VO2 max) below the guideline thresholds for eligibility for surgical resection and/or associated with severe co-morbidities. The protocol included a cardiorespiratory rehabilitation program and 3 hours of NIV each day. Functional tests were repeated after 3 weeks of therapy. RESULTS: Participants displayed a significant increase in their FEV1 and VO2 max, which allowed surgical resection to go ahead in all patients (lobectomy, n=15; pneumonectomy, n=3; bilobectomy, n=2). The morbidity rate was 20% (acute renal failure, n=2; pneumonia, n=1; haemothorax, n=1). The mortality rate was 5% (myocardial infarction, n=1). Further postoperative rehabilitation allowed a return at home in 19 patients after a mean hospital stay of 11 days. CONCLUSION: Pulmonary rehabilitation associated with a period of preoperative NIV allows surgery to be performed in patients who are not initially eligible for resection. An evaluation of long-term outcomes survival in comparison to non-surgical therapies is necessary.

RESUMO

The purpose of this multicentric Phase II study was to evaluate the safety and efficacy of a gemcitabine/oxaliplatin/vinorelbine combination as first-line therapy in advanced non-small cell lung cancer patients. Patients followed a fortnightly drug schedule, receiving on day 1, vinorelbine 25mg/m(2) (20-min infusion); gemcitabine 700 mg/m(2) (70-min infusion, fixed 10mg/m(2)/min); and on day 2, oxaliplatin 85 mg/m(2) (2-h infusion). Thirty-nine patients with a median age of 58 years received a total of 306 cycles (median 8 cycles); 67% were males. Most had adenocarcinoma (51%), large-cell (23%) and squamous cell carcinoma (21%); 15% had stage IIIB and 85% stage IV. There was one complete response (3%; 95% CI: 0.1-13%), 15 partial responses (PR) (38%; 95% CI: 23-55%), and 13 patients with stable disease (33%; 95% CI: 19-50%) of at least 2 months duration, for an overall non-progression rate of 74%. Median progression-free survival (PFS) was 4.1 months (95% CI: 3.1-8.7) and overall survival was 11.7 months (95% CI: 7.7-19.4). No treatment-related deaths occurred and very few grade 3-4 events were observed. Overall, the regimen was well tolerated and the planned recommended dose intensity was safely delivered to more than 95% of patients. This triple combination therapy study yielded favourable efficacy and toxicity results, which merit further evaluation in prospective randomised trials.

RESUMO

BACKGROUND: Oxaliplatin and vinorelbine are both active agents against non-small-cell lung cancer (NSCLC). In a previous phase I trial, we showed that oxaliplatin (130 mg/m2, day 1) and vinorelbine (26 mg/m2/day, days 1 and 8) can be safely combined when given every 21 days. We completed the evaluation of this new platinum-based doublet in advanced NSCLC patients in a multicenter phase II study. PATIENTS AND METHODS: Twenty-eight chemotherapy-naïve patients (22 men and six women: median age 58 years, range 33-70), including 20 with stage IV disease, received this out-patient combination, with 5-hydroxytryptamine-3-receptor agonists as the only prophylactic measure. RESULTS: A total of 117 cycles were given, for a median of three per patient (range 1-8). Of 26 eligible patients, nine achieved a partial response (WHO criteria), giving an objective response rate of 35% [95% confidence interval (CI) 17% to 56%]. The median progression free survival was 5.0 months (95% CI 3.1 to 6.9), median overall survival was 9.8 months (95% CI 2.2 to 17.5) and the 1-year survival rate was 37%. Neutropenia was the principal toxicity, grade 4 occurring in 11 patients (39%) and 25 cycles (22%). Four patients (14%) experienced one episode of febrile neutropenia each. Acute oxaliplatin-related neurosensory toxicity was prevalent, but was mild to moderate in the majority of patients (82%) and reversible. Grade 1/2 vomiting (65% of patients) and diarrhea (32% of patients) were easily managed. CONCLUSIONS: The oxaliplatin-vinorelbine doublet is a safe and active out-patient combination. It may represent an interesting alternative in the management of patients with NSCLC, and serve as a new doublet to which other active agents could be added.

RESUMO

PURPOSE: Oxaliplatin is a platinum compound active in non-small-cell lung cancer (NSCLC) patients, and vinorelbine (VNB) is an active reference agent. This phase I/II study was performed to determine the dose-limiting toxicity (DLT), the maximum-tolerated dose (MTD), and the recommended dose (RD) of a VNB/oxaliplatin combination given to previously untreated patients with advanced NSCLC. PATIENTS AND METHODS: Oxaliplatin was given at the fixed dose of 130 mg/m2 (2-hour intravenous [IV] infusion) on day 1. VNB was administered on days 1 and 8 (10-minute IV infusion), with doses starting at 22 mg/m2/d and escalated by 2 mg/m2 increments until MTD. Treatment was repeated every 3 weeks. No special hydration measures or prophylactic granulocyte colony-stimulating factors were used. RESULTS: Twenty-seven patients (20 men, 7 women) received 110 cycles total at six different VNB dose levels. Neutropenia was the DLT. Although no patient experienced DLT at the highest dose level (32 mg/m2/d), multiple treatment delays (54% of cycles) and dose reductions (34% of cycles) were required at this dose level. Others toxicities were mainly limited to grade 1 peripheral neuropathy and grade 1/2 nausea/vomiting. The relative dose-intensity of administered VNB from dose levels 3 to 6 (26 to 32 mg/m2) remained stable, whereas grade 3/4 neutropenia increased. All patients were assessable for activity; there were 10 objective responses, including one complete response (37% response rate). CONCLUSION: The present combination can be safely administered in an outpatient setting. The RD is VNB 26 mg/m2 days 1 and 8 with oxaliplatin 130 mg/m2 day 1 every 3 weeks.

RESUMO

The aim of this phase II study was to determine the antitumour activity and safety of trans-1-diaminocyclohexane-platinum (oxaliplatin) in previously untreated advanced non-small cell lung cancer (NSCLC) patients. 33 patients with unresectable and measurable NSCLC were entered into this phase II study between January 1992 and January 1994. Patients had either locoregional disease with performance status 2 (19 patients) or a stage IV disease (14 patients). Oxaliplatin (130 mg/m2) was given on an out-patient basis (2-h infusion, every 21 days) without hydration. Response was assessed after every two courses. One hundred courses were administered, with a mean of three courses per patient (range 1-12). All patients were evaluable for response; 1 had a complete response, and 4 a partial response (overall response rate 15%, 95% confidence interval 5.1-31.9%). The median response duration was 5.9 months. All cycles (n = 100) were evaluable for toxicity assessment. Transient reversible, cold-related finger dysesthesias occurred in 29 patients, but were mild, and disappeared in most cases within a few days. We observed brief episodes of pharyngolaryngeal discomfort (8 patients, 11 episodes) accompanied in 4 cases (3 patients), by transient episodes of inspiratory stridor, leading 2 patients to treatment withdrawal. We conclude that oxaliplatin has activity in poor-prognosis NSCLC and that this treatment is feasible in out-patients; the absence of renal and haematological toxicity makes this drug a good candidate for further evaluation in NSCLC.

RESUMO

Although respiratory changes induced by tobacco smoke have been extensively described, no study has focused on ciliary abnormalities associated with chronic smoking. Ciliary ultrastructure was studied in 37 adults with chronic sputum production (CSP) consisting of 13 current smokers (Group 1), 5 ex-smokers (Group 2), and 19 nonsmokers (Group 3). Five healthy nonsmokers constituted the control group (Group 4). Clinical and radiologic data and respiratory function tests were recorded. Acute respiratory infection was diagnosed by culture of tracheobronchial secretions obtained during bronchoscopy. Bronchial ciliated cells were obtained and processed for transmission electron microscopy. Within each group, the percentages of abnormal cilia were similar in patients with either chronic bronchitis or bronchiectasis and in patients with or without acute infection. The percentage of axonemal ultrastructural abnormalities (AUA) was higher in smokers (16.5% +/- 2.7%) and ex-smokers (17.5% +/- 7%) than in nonsmokers (5.2% +/- 1%) or control subjects (0.7% +/- 0.2%) (p < 0.0002). The AUA were polymorphic, characteristic of acquired ultrastructural changes. These results suggest that chronic smoking may induce an increased number of abnormal cilia which could participate in impairment of tracheobronchial clearance and which appears to be independent of the etiology of CSP.

RESUMO

Two-hundred two patients with limited small cell lung cancer were tested by four consecutive alternating radiotherapy and chemotherapy protocols. The alternating schedule consisted of six cycles of chemotherapy (doxorubicin, etoposide, and cyclophosphamide, plus methotrexate in the first protocol; cisplatin replaced methotrexate in the other three protocols) and three courses of thoracic radiotherapy at a total dose of 45, 55, 65 and 61 Gy in the four consecutive protocols, respectively. A 1-week rest followed each chemotherapy cycle and each course of radiotherapy. Seventy-six percent of patients were in complete remission at the end of the induction treatment. Overall results showed a 2-year cumulative incidence rate of failure of 75%. The first cause of failure was local recurrence only, 33%; distant only, 25%; distant and local simultaneously, 9%; and intercurrent death, 8%. Overall survival rate at 5 years was 16%. No significant differences were observed between the four treatment groups. Alternating radio-chemotherapy approaches are feasible and currently included in Phase III trials.

RESUMO

A 24-year-old man had a mediastinal embryonal carcinoma containing yolk sac foci. Combination chemotherapy with cisplatin, bleomycin, etoposide, and vinblastine was given, and the residual mass was then resected. Histology showed only necrotic cells. No other treatment was given. Two years later the patient presented with episodes of flushing and syncopes related to a systemicmastocytosis. Bone marrow examination showed a diffuse infiltration with large, atypical mast cells often with multilobulated nuclei. The patient suffered several episodes of cardiovascular collapse and died during one of these episodes, 8 months after the diagnosis of systemic mastocytosis and 40 months after the diagnosis of mediastinal tumor. Autopsy findings included the absence of mediastinal tumor and a diffuse liver and spleen mast cell infiltration. This was the second case with the similar clinicopathologic picture of two rare diseases being associated. This fact supports the hypothesis of a distinct entity, part of the mediastinal germ cell tumor/hematologic malignancy syndrome. The hypothesis of a cytokine secretion induced by mediastinal germ cell tumor supporting mast cell proliferation may be considered.

RESUMO

Two chemotherapy regimens for patients with extensive small-cell lung cancer were prospectively compared in a randomized multicentric trial with crossover. Every four weeks, 60 consecutive previously untreated patients received either DPE (doxorubicin, cisplatin and etoposide), or CIV (carboplatin, ifosfamide and vincristine) with crossover as soon as progression or end of response were observed. Pretreatment characteristics were similar in the two groups. Fifty-seven patients were evaluated for response. The response rate was higher with the DPE regimen both in first-line (for DPE: response rate 62% (18/29), including 17% (5/29) of complete response (CR), and for CIV: response rate 29% (8/28) with no CR, p < 0.02) and in second-line after crossover (for DPE: response rate 45% (9/20) including 5% (1/20) of CR, and for CIV response rate 0%, p < 0.02). Major toxicities were equally frequent in both groups. No significant difference was found between median survival times (9.7 months for the DPE group and 10.4 months for the CIV group). We conclude that: 1) DPE is a more active regimen than CIV, both in first- and second-line; 2) no alternating scheme may be considered with these two combinations. Of particular note is the similar median survival times in the two groups, contrasting with the different activities of the two regimens.

RESUMO

Dyskeratosis congenita (DC) is an unusual familial disorder primarily affecting the skin and its appendages. We report the case of a DC patient with chronic respiratory tract involvement, confirming the features previously reported by a small number of authors: 1) chronic bronchoalveolar involvement is not unusual in this disorder; 2) the main features are early sputum production with subsequent bronchial and alveolar destruction; 3) after onset of dyspnoea the course is rapidly fatal, with progressive respiratory failure. Immune deficiency and repeated bronchoalveolar infections may be involved in the pathogenesis of these manifestations.

RESUMO

The cytogenetic study of five cases of untreated adenosquamous carcinoma of the lung allows us to propose a number of characteristic anomalies. All tumor cells were hyperdiploid, with a mean chromosome number ranging from 59 to 83, and had many clonal chromosome rearrangements. The chromosomes the most frequently affected by these rearrangements were, by decreasing order, 1, 3, and 15; 7 and 8; and 17. No recurrent breakpoints were observed in euchromatic regions, most breaks (45/66) involving juxtacentromeric heterochromatin or immediately adjacent regions. Although chromosome 3 was frequently rearranged, no recurrent deletions of its short arm were observed.

RESUMO

PURPOSE: We report results in terms of relapse-free survival (RFS), obtained in patients with limited small-cell lung carcinoma (SCLC) treated by four consecutive alternating protocols, using a competing risk approach with local recurrences, distant metastases, and death unrelated to cancer as competing events. PATIENTS AND METHODS: Two hundred two patients with limited SCLC were included in four consecutive protocols alternating radiotherapy and chemotherapy (CT). The alternating schedule consisted of six cycles of CT (doxorubicin, etoposide [VP16213], and cyclophosphamide [CAVP16], plus methotrexate in the first protocol; cisplatin replaced methotrexate in the other three protocols) and three courses of thoracic radiotherapy at a total dose of 45, 55, 65, and 61 Gy in the four consecutive protocols, respectively (accelerated hyperfractionation was used in the first course of the fourth protocol). A 1-week rest followed each CT cycle and each course of radiotherapy. Seventy-six percent of patients were in complete remission at the end of the induction treatment. RFS variables were determined according to a model assuming competing risks to define the first cause of failure (local disease, distant metastasis, or intercurrent death). RESULTS: No significant differences were observed between the four treatment groups. Overall results showed a 2-year cumulative incidence rate of failure of 75%. When analyzed, the first cause of failure was local recurrence only, 33%; distant only, 25%; distant and local simultaneously, 9%; and intercurrent death, 8%. CONCLUSIONS: The methodology of competing risks allowed an unequivocal description of first events in limited SCLC. The extent of the local problem has been relatively overshadowed by the use of conventional descriptive methods.

RESUMO

Seventy-five patients with locally advanced non small cell lung carcinoma were entered in a phase II study combining chemotherapy (vindesine, lomustine, cisplatin and cyclophosphamide) and radical thoracic radiotherapy delivering a total dose of 60-65 Gy. Patients were regularly assessed by radiological and fiberoptic bronchoscopy examinations in order to evaluate local control. An objective response was observed in 22 patients (29%) after initial chemotherapy (2 complete remissions and 20 partial responses). The complete response rate after the combined schedule was 30%. Toxicity of this combination was acceptable. Median survival was 13.5 months. Actuarial risk of developing distant metastases at 3 years was 60%. However, the main cause of failure was local with 80% of uncontrolled or recurrent thoracic tumor in the first 2 years of follow-up. The present study shows that local control remains a major problem in the management of patients with inoperable non metastatic non small cell lung cancer.

RESUMO

To evaluate the prevalence of inherited respiratory ciliary structure and underlying mucus abnormalities in the diffuse bronchiectasis syndrome, we investigated 53 subjects comprising 38 patients with diffuse bronchiectasis confirmed by high-resolution thoracic computed tomography, ten with chronic bronchitis and no diffuse bronchiectasis and five healthy nonsmoking control subjects. The clinical history was determined by means of a standardized questionnaire. Axonemal abnormalities of respiratory cilia were evaluated on bronchial or nasal mucosa samples by transmission electron microscopy (structure) and stroboscopic observation (function). Cystic fibrosis (CF) and Young's syndrome were detected by means of the sweat test and semen analysis when male infertility was suspected. Among the 38 patients with diffuse bronchiectasis, a primary ciliary dyskinesia (PCD) was detected in five (13%) with a high proportion (range: 55-100%) of cilia showing axonemal ultrastructural abnormalities always involving the dynein arms. The prevalence of this inherited condition was higher in North African (36%) than in European patients (4%) (p less than 0.01). After exclusion of the five patients with PCD, the patients with diffuse bronchiectasis showed axonemal ultrastructural abnormalities similar to those with chronic bronchitis. The diagnosis of underlying mucus disorders was based on two types of criterion, i.e. for CF, sweat chloride levels greater than 80 mmol.l-1, or the combination of diagnostic criteria proposed by Stern et al. Respectively, five (three Young's syndrome and two CF) and seven (one Young's syndrome and six CF) cases of inherited mucus disorders were suspected. Our results showed that PCD was highly prevalent among the adult North African patients with diffuse bronchiectasis but relatively rare in the Europeans.

RESUMO

Most patients with locally advanced non small cell lung carcinoma are treated with external thoracic radiotherapy. Because of the high incidence of distant metastasis the addition of chemotherapy has been proposed. The present randomized study was conducted from June 1983 to February 1989 and included 353 patients. The trial compared arm A, thoracic megavoltage radiotherapy alone at a total dose of 65 Gy in 26 fractions and 45 days, to arm B that comprised the same radiotherapy preceded and followed by 3 monthly cycles of VCPC (vindesine 1.5 mg/m2 d 1-2, cyclophosphamide 200 mg/m2 d 2-4, cisplatinum 100 mg/m2 d 2 and lomustine 75 mg/m2 d 3). Disease was deemed unresectable but non-metastatic after bronchoscopic, radiologic, CAT, and nuclear scans and physical examinations. Only patients in clinical, radiological, endoscopic, and histological complete remission were considered as locally controlled; these patients were monitored by fiberoptic bronchoscopy and systematic biopsies to the primary site. One hundred seventy-seven patients received thoracic radiotherapy alone and 176 received the combined modality. Twenty-seven percent of arm B patients had an objective response after 2 VCPC cycles. At the time of final assessment, performed 3 months after the end of thoracic radiotherapy in both arms, there were 20% of complete responders in arm A versus 16% in arm B. The two-year survival rate was 14% in arm A versus 21% in arm B (p = 0.08, logrank test). The distant metastasis rate was 67% in arm A versus 45% in arm B (p less than 0.001). Local control at 1 year was poor in both groups (17% and 15%, respectively). The striking effect of VCPC chemotherapy on the incidence of distant metastasis did not have a significant impact on overall survival. We conclude that thoracic tumor control remains a significant problem in unresectable non small cell lung cancer.

RESUMO

1. Determination of debrisoquine oxidation phenotype was carried out in 119 healthy subjects, 135 patients with chronic bronchitis and 153 patients with lung cancer, all of Caucasian origin. 2. A non-Gaussian distribution of the log D/HD ratio was observed in the three groups. 3. Assuming an antimode of 1.12, the proportion of PMs was found to be 6.7% in healthy subjects, 8.9% in chronic bronchitics and 6.5% in patients with lung cancer. These differences were not significant. 4. The presence of a lung tumour itself had no influence on phenotype in a group of 14 patients who were phenotyped before and after surgery. 5. We conclude that a link between debrisoquine phenotype and lung cancer is unlikely.

RESUMO

The first known case of systemic mast cell disease associated with a germ cell tumor is reported. Six months after the complete remission of a primary mediastinal germ cell tumor treated by chemotherapy and resection, a young man had a series of episodes of hypotension and syncope and, a few months later, a gastric hemorrhage and coagulation disorder. The diagnosis of systemic mast cell disease was made in view of bone marrow and liver biopsies. A transient circulating heparin-like anticoagulant was noted. The occurrence in a short period of these two unusual conditions, given previous knowledge of hematologic disorders associated with germ cell tumors, suggests that the present association is not a coincidence. Systemic mast cell disease should be considered among the hematologic disorders associated with a germ cell tumor.

RESUMO

An analysis of the chest recurrences was conducted in 72 consecutive patients with limited small cell lung cancer treated in two successive phase II trials alternating six induction chemotherapy courses and three series of thoracic radiotherapy, followed by maintenance chemotherapy. The total radiation dose was 45 Gy (3 series of 15 Gy) in the first trial, and 55 (20, 20 and 15 Gy) in the second. The effect of the irradiated volume was investigated by comparing the local relapse rates in the group of patients treated by radiation fields encompassing the initial tumor volume to another group in which the initial target volume was not fully covered by radiation fields. The definition of these two groups was performed retrospectively by examination of radiological, fiberoptic bronchoscopy initial findings, technical radiation charts and check films. The local recurrence rate were 33 and 36% in each group (no significant difference). This finding could suggest that tumor shrinkage after chemotherapy might allow the use of "reduced" radiation volumes. However, the limited number of patients does not permit a definite conclusion. The effect of radiation dose was investigated by comparing the local control rates in the two consecutive trials which delivered 45 and 55 Gy, respectively. No difference in long-term local control was found: the addition of 10 Gy in the second trial only seemed to delay the appearance of local recurrences by 6 months. Twenty percent of patients died from a local relapse without evidence of distant metastases.(ABSTRACT TRUNCATED AT 250 WORDS)
