Gemcitabine and carboplatin in the treatment of locally advanced and metastatic non-small cell lung cancer 总被引:1,自引:0,他引:1
OBJECTIVE: The aim of the study was to evaluate the response, survival advantage and toxicity profile of gemcitabine-carboplatin combination cytotoxic chemotherapy in patients with locally advanced and metastatic non-small cell lung cancer (NSCLC). METHODOLOGY: Patients who received gemcitabine-carboplatin combination chemotherapy over a 2.5-years period were analyzed. Carboplatin at a dose of 5 mg/mL/min (area under the concentration-time curve) was given on day 1 and gemcitabine (1000 mg/m(2)) on days 1 and 8, every 3 weeks. RESULTS: Of 49 chemotherapy-naive patients (median age, 62 years) who received this treatment, 57% were males, 12% had stage IIIa, 39% stage IIIb and 49% metastatic disease. The Eastern Cooperative Oncology Group (ECOG) performance status of 70% of the patients was 1 at the time of commencement of chemotherapy and 2 for the remaining 30% of patients. The overall response rate, based on 33 evaluable patients, was 27.3%. The response rate was not affected by age, stage of disease or performance status. The median survival was 9 months. Median survival among patients with an ECOG performance status of 1 was 11 months, as compared with 4 months for patients with an ECOG performance status of 2 (P < 0.001). Toxicity was generally well tolerated and there were no treatment-related deaths. CONCLUSIONS: Gemcitabine-carboplatin combination chemotherapy is an effective and well-tolerated cytotoxic regimen among Malaysian patients with advanced NSCLC. A performance status of 1 or less was associated with a better survival. 相似文献

Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data. 相似文献

A clinical-severity staging system for patients with lung cancer 总被引:4,自引:0,他引:4
The prognostic staging of cancer in general, and lung cancer in particular, has customarily depended mainly on morphologic distinctions. The gross anatomic extensiveness of cancers is cited with TNM stages that describe the primary tumor (T), spread to regional lymph nodes (N), and metastatic dissemination (M) to distant sites. Microscopic characteristics are cited according to the cancer's cell type (e.g., adenocarcinoma, epidermoid carcinoma) and/or grade of differentiation (e.g., well differentiated, poorly differentiated, anaplastic). Although the clinical manifestations, functional effects, and associated co-morbidity of a cancer are universally recognized as having major prognostic importance, they have not been classified with a standard system of taxonomy. When considered at all, clinical phenomena have been cited with a surrogate index of "performance status" that ignores the underlying clinical dysfunctions while being greatly affected by non-clinical phenomena, such as the patient's psychic status, economic motivations, and system of social support. The current research was done to develop a standard system of taxonomy (or "staging") for the prognostic impact of clinical distinctions in patients with primary lung cancer. Appropriate data were obtained, computer-coded, and analyzed from medical records for the complete clinical course of an inception cohort of 1266 patients who were first treated at either the Yale-New Haven Hospital or the West Haven Veterans Administration Hospital during the interval January 1, 1953-December 31, 1964. The information under analysis included clinical phenomena as well as anatomic extensiveness (TNM stage), microscopic histology, the chronometric duration of the interval from the first symptom of lung cancer to zero time, the iatrotropic reason why the patient sought medical attention, the presence of anemia, the amount of customary cigarette use, and the conventional demographic data for age and gender. The main clinical phenomena were expressed in variables for symptom pattern severity, and co-morbidity. Symptom pattern referred to the existence of specific pulmonic symptoms (e.g., hemoptysis), systemic symptoms (e.g., complaint of weight loss), and metastatic symptoms that might be mediastinal (e.g., superior vena cava syndrome), regional (e.g., the Horner syndrome), or distantly metastatic (e.g., central nervous system). The symptom severity variable included the amount of weight loss, and the existence of severe dyspnea or particularly severe tumor effects (such as mental obtundation, rather than hemiparesis in patients with CNS metastasis). Prognostic co-morbidity was cited for coexisting diseases, such as recurrent myocardial infarctions, that might be more lethal than the lung cancer itself.(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献

INTRODUCTION: Cancer in the elderly is a common health issue in developed societies. We sought to present epidemiology, management and outcome data on fit elderly patients with common metastatic cancers and to identify predictors of clinical benefit from palliative chemotherapy. METHODS: All patients aged >65 years who were diagnosed with metastatic breast, colorectal or non-small cell lung carcinomas and managed with palliative chemotherapy in the context of Hellenic Cooperative Oncology Group (HeCOG) clinical trials or protocols were eligible for electronic data retrieval and analysis. Common eligibility criteria included adequate performance status (ECOG 0-3), organ function and absence of severe co-morbidity forbidding cytotoxic chemotherapy. RESULTS: One thousand three hundred and seventy-two fit patients (PS 0-1 in 73%) with a median age of 70 years diagnosed with metastatic breast (n=250), colorectal (n=621) or lung cancer (n=501) received chemotherapy from 1991 until 2006. Most patients received modern full-dose chemotherapy regimens including platinum, taxanes, anthracyclines, fluoropyrimidines, oxaliplatin or irinotecan. Mild to moderate co-morbidity was present in 35%. At a median follow-up of 3 years, objective responses were seen in 41% of patients with breast cancer, 25% with colorectal cancer and 31% with lung cancer, while median survival was 21, 16 and 9.4 months, respectively. Grade 3 or 4 toxicity was seen in a quarter of patients, the most common being neutropenia (14%), diarrhoea (6%), neurotoxicity (4%), fatigue, nausea and febrile neutropenia (each 2%). In multivariate analysis, diagnosis of colorectal or lung cancer, metastases in multiple organ sites, presence of liver/brain/peritoneal deposits, impaired PS and low baseline serum albumin levels were prognostic factors for adverse outcome. The same factors excluding metastatic sites and with the addition of anemia predicted for resistance to chemotherapy. Toxicity was more likely in females with low serum albumin and renal dysfunction. A six-variable geriatric assessment for palliation (GAP) score that included tumour type, sites of metastatic dissemination, impaired PS, low serum albumin and anemia classified elderly patients to groups with low, intermediate and high risk for disease progression and death (relative risks of 1.59 and 2.50 for resistance to therapy and 1.87 and 3.12 for death in the intermediate and high-risk groups). CONCLUSIONS: Our data indicate that relatively fit elderly patients with advanced cancer safely tolerate modern chemotherapy and enjoy disease control in a manner comparable to younger patients. Our GAP score, if further validated, offers promise for geriatric application in combination to comprehensive geriatric assessment tools for the optimisation of palliative therapy on an individualised basis. 相似文献

To determine the stage of the disease, performance status of the patients on admission and treatment modalities, records of 226 patients with lung cancer diagnosed between January 1992 and December 1999 were evaluated retrospectively. The mean age of the patients were 61.3 +/- 10.3 years (mean +/- standard deviation) and 217 (96%) were men and 9 (4%) were women. Of the 192 cases with non-small cell lung cancer 22.9% were stage 4, 40.6% were stage 3b, 22.4% were stage 3a, 4.2% were stage 2, 9.9% were stage 1. Of the 34 (15.1%) patients with small cell lung cancer, 26.5% were extensive and 73.5% were in limited stages. The performance status according to European Cooperative Oncology Group (ECOG) was between 0-2 in 88.4% and 3-4 in 11.6% of the cases. A positive correlation between the performance status and the stage of the disease was observed (p= 0.0331). It was detected that the performance status of the patients who underwent surgery was better than the patients who treated with radiotherapy (p= 0.0008). Radiotherapy (RT), chemotherapy (CT), surgery, combined therapy (RT + CT), adjuvant RT and palliative therapy were performed in 27%, 20.4%, 11.5%, 1.3%, 1.8% and 14.6% of the cases respectively. No information about treatment protocol was able to obtained in 23.4% of the patients, probably due to referrals, early deaths etc. In conclusion, more than half of our cases with lung cancer were diagnosed in advanced stages as a possible result of late admission to physician and surgery were performed in only a small part of the cases. It was detected that performance status of the patients operated was better than the patients treated with radiotherapy. On the other hand, combination therapy was applied in few cases. 相似文献

Background: Accurate staging of lung cancer is essential in determining the most appropriate management plan, as detection of occult metastasis can significantly alter management. Aims: The aims of this study are to determine the prevalence of occult metastasis in patients undergoing 2‐18F‐fluoro‐2‐deoxy‐D ‐glucose (18F‐FDG) positron emission tomography (PET) for evaluation of suspected/proven lung carcinoma and correlate pre‐PET TNM stage with prevalence of metastasis. Methods: FDG‐PET, which identified patients with metastasis on institutional database, was re‐evaluated by a nuclear medicine physician blinded to clinical information. The confidence level of metastasis was scored on a 5‐point scale, with a score of ≥4 considered positive. Results: There were 67 of 645 (10%) patients identified with suspected occult metastasis on FDG‐PET. Twelve patients scoring ≤3 were excluded. Prevalence of occult metastasis was 10/156 (6%) in solitary pulmonary nodules (SPN); 22/319 (7%) and 23/170 (14%) in proven and suspected lung cancer, respectively. Positive predictive value of FDG‐PET for metastasis was 8/10 (80%) in solitary pulmonary nodules, 14/20 (70%) and 17/21 (81%) in proven and suspected lung cancer, respectively. 18F‐FDG‐avid lesions classified as false positives were patients with cholelithiasis, rib fractures and those with equivocal/negative bone scans or computed tomography on follow up. There was a higher incidence of true positive occult metastasis in patients in all stages of disease, particularly stage III disease. Conclusion: 18F‐FDG PET is predictive for occult metastatic disease in patients with solitary pulmonary nodules and proven or suspected lung cancer and is more likely to be present in all stages, particularly in stage III. PET findings should be actively pursued with correlative investigation to identify benign pathology in patients who remain candidates for curative treatment. 相似文献
