Multicenter Phase II Trial of Carboplatin/Vinorelbine in Elderly Patients with Advanced Non–Small-Cell Lung Cancer–Efficacy and Impact on Quality of Life: Groupe Français de Pneumo-Cancérologie Study 9902

Use of the lung cancer-specific Quality of Life Questionnaire EORTC QLQ-LC13 in clinical trials: A systematic review of the literature 20 years after its development

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) covers 13 typical symptoms of lung cancer patients and was the first module developed in conjunction with the EORTC core quality-of-life (QL) questionnaire. This review investigates how the module has been used and reported in cancer clinical trials in the 20 years since its publication. Thirty-six databases were searched with a prespecified algorithm. This search plus an additional hand search generated 770 hits, 240 of which were clinical studies. Two raters extracted data using a coding scheme. Analyses focused on the randomized controlled trials (RCTs). Of the 240 clinical studies that were identified using the LC13, 109 (45%) were RCTs. More than half of the RCTs were phase 3 trials (n = 58). Twenty RCTs considered QL as the primary endpoint, and 68 considered it as a secondary endpoint. QL results were addressed in the results section of the article (n = 89) or in the abstract (n = 92); and, in half of the articles, QL results were presented in the form of tables (n = 53) or figures (n = 43). Furthermore, QL results had an impact on the evaluation of the therapy that could be clearly demonstrated in the 47 RCTs that yielded QL differences between treatment and control groups. The EORTC QLQ-LC13 fulfilled its mission to be used as a standard instrument in lung cancer clinical trials. An update of the LC13 is underway to keep up with new therapeutic trends and to ensure optimized and relevant QL assessment in future trials.

Management of elderly patients

SUMMARY

Elderly patients are often excluded from clinical trials, yet more than two-thirds of patients diagnosed with lung cancer are over 65 years old. It is therefore important to develop specific tools and trials for this specific patient population.

METHODS

This chapter first examines the management specificities of elderly patients. Randomized trials specifically involving elderly patients are then described, and likely future developments are considered.

RESULTS

Older people have several specificities. In addition to traditional criteria such as age and performance status, other important factors include the number of comorbidities and age-related changes such as cognitive deficits and depression. Specific indices taking these factors into account have been published and validated. Single-agent therapy has been widely used to treat metastatic lung cancer in the elderly, following publication of negative results from randomized phase III trials of combination chemotherapy. Recently, however, a trial of doublet therapy gave positive results, in a subgroup of independent older patients. The benefit of patient selection based on a combination of these indices has been demonstrated in open-label and randomized trials. These results must now be confirmed in phase III trials including the use of tyrosine kinase inhibitors combined with chemotherapy.

CONCLUSIONS

Indices based on a combination of age-related factors, together with judicious use of biological markers, will further improve the prognosis of elderly lung cancer patients.

Health-related quality of life questionnaires in lung cancer trials: a systematic literature review

BACKGROUND

Lung cancer is one of the leading causes of cancer deaths. Treatment goals are the relief of symptoms and the increase of overall survival. With the rising number of treatment alternatives, the need for comparable assessments of health-related quality of life (HRQoL) parameters grows. The aim of this paper was to identify and describe measurement instruments applied in lung cancer patients under drug therapy.

METHODS

We conducted a systematic literature review at the beginning of 2011 using the electronic database Pubmed.

RESULTS

A total of 43 studies were included in the review. About 17 different measurement instruments were identified, including 5 generic, 5 cancer-specific, 4 lung cancer-specific and 3 symptom-specific questionnaires. In 29 studies at least 2 instruments were used. In most cases these were cancer and lung cancer-specific ones. The most frequently used instruments are the EORTC QLQ-C30 and its lung cancer modules LC13 or LC17. Only 5 studies combined (lung) cancer-specific questionnaires with generic instruments.

CONCLUSIONS

The EORTC-C30 and EORTC-LC13 are the most frequently used health-related quality of life measurement instruments in pharmacological lung cancer trials.

An open multicenter phase II trial of docetaxel–gemcitabine in Charlson score and performance status (PS) selected elderly patients with stage IIIB pleura/IV non-small-cell lung cancer (NSCLC): The GFPC 02-02a study

The aim of this study was to determine the impact of patient selection based on age, comorbidity and performance status on the efficacy of platinum-free combination therapy on non-small-cell lung cancer after 65 years of age. We analyzed the overall response rate, the median survival time, the 1-year survival rate, toxicity and quality of life after one to three 6-week cycles of docetaxel 30mg/m(2) weekly and gemcitabine 900mg/m(2) at weeks 1, 2, 4 and 5. Fifty patients (median age 73.7 years) were eligible. The mean number of comorbid conditions per patient was 0.8 [Balducci L. Lung cancer and aging. ASCO 2005. Educational book. p. 587-91; Piquet J, Blanchon F, Grivaux M, et al. Primary bronchial carcinoma in elderly subjects in France. Rev Mal Respir 2003;20:691-9; Jatoi A, Hillman S, Stella P, et al. Should elderly non-small-cell lung cancer patients be offered elderly-specific trials? Results of a pooled analysis from the North Central Cancer Treatment Group. J Clin Oncol 2005;23:9113-9; Balducci L, Extermann M. Management of cancer in the older person: a practical approach. Oncologist 2000;5:224-37]. Forty-five patients were assessable: 17 (34%) had an objective response, 18 (36%) had stable disease and 10 progressed (20%). The median survival time was 7 months and the 1-year survival rate 23.5%. The main grade III-IV adverse event was neutropenia (32% of patients).

CONCLUSION

Platinum-free dual-agent chemotherapy gives similar results in patients over 65, selected on the basis of their precise age and comorbidity, to that reported in younger subjects.

Lung cancer in elderly patients: A retrospective analysis of practice in a single institution

Incidence of non-small cell lung cancer is increasing especially among elderly with about 40% arising in patients over 70 years old. Most of these elderly patients are under treated. Seventy-one patients with lung cancer over 70 years old were treated in Institut Paoli-Calmettes from January 2000 until December 2003 (male/female: 57/14). Median age was 75.5 years (70-92). OMS 0-1-2-3=4.2-60.6-25.4-4.2%, respectively. Comorbidities were represented by arterial hypertension, coronaropathy, cardiac failure, thrombo-embolism, respiratory failure, diabetes, vascular cerebral dysfunction, and renal failure. 29.6% of patients were without comorbidity, and 14.1% had at least three comorbidities. The averages of the Charlson comorbidity score and the Age-Charlson comorbidity score were 3.4 and 6.6, respectively. Histological characteristics: epidermoïd/adenocarcinoma/undifferentiated/small cells: 39.4%/26.8%/15.5%/9.9%. Most of them were advanced lung cancer: St IIIB=14 (19.7%) and St IV=37 (52.1%). Forty-six patients received chemotherapy (64.8%) with 40 patients (86.9%) with platin (carboplatin or cisplatin). The median number of treatment cycles was 4.1 (range 1-7). Two patients achieved complete response and 15 had partial response. The response rate was 39.6%. The 1-year survival rate was 48.5% and the estimated median survival time was 11 months (95%; 7-18 months) for all patients. The 1-year survival rate was 75% and 21.6% and the estimated median survival time was 25.9 months (95%; 12.6, ND) and 5.7 months (95%; 4.2-9.6) for stage IIIB and IV, respectively. Toxicities were judged acceptable with 19 hospitalizations after chemotherapy, for 16 patients who represent 34.8% of patients who received chemotherapy.

CONCLUSIONS

Chemotherapy is feasible in elderly patients with lung cancer. Patients should be evaluated for chemotherapy based on their performance status and comorbidities especially with geriatric assessment rather than age alone. The chemotherapy with platinum seems to be tolerable and effective.

A phase II trial of carboplatin/vinorelbine with pegfilgrastim support for the treatment of patients with advanced non-small cell lung cancer

INTRODUCTION

The impact of chemotherapy dose delivery has not been well studied in patients with non-small cell lung cancer (NSCLC). Overlapping hematologic toxicities commonly limit planned dose intensity of combination chemotherapy regimens. A phase II study investigating carboplatin and vinorelbine, supported by pegfilgrastim, in the treatment of patients with advanced NSCLC was performed.

METHODS

Chemotherapy-naïve patients with locally advanced or metastatic NSCLC were treated with carboplatin area under the curve (AUC) 6 mg/ml per minute intravenously on day 1 and vinorelbine 30 mg/m2 intravenously on days 1 and 8 every 3 weeks for four planned cycles. Pegfilgrastim was administered on day 9 of each cycle as a 6-mg subcutaneous injection. The primary endpoint was incidence of cycle 1 febrile neutropenia. Secondary endpoints included incidence of grade 3/4 hematologic and nonhematologic toxicities, delivered dose intensity, and overall survival.

RESULTS

Thirty patients (21 men, 9 women) with a median age of 61 years (range, 43-79) were enrolled. Of 120 planned patient cycles, 101 (84%) were completed. There was one episode of cycle 1 febrile neutropenia. Overall response rate was 27%. Median dose delivered for vinorelbine was 17.2 mg/m2 per week, representing a delivered dose intensity of 86%. Median survival was 9.4 months (95% confidence interval: 6.1-18.0) with a 3-year survival rate of 20%.

CONCLUSIONS

This regimen of carboplatin and vinorelbine with pegfilgrastim support was associated with a low rate of febrile neutropenia and good maintenance of planned dose intensity. Although response and survival are similar to other chemotherapy regimens in advanced NSCLC, studies optimizing chemotherapy delivery in this setting may help inform treatment approaches in patients with earlier stage disease.

An open multicenter phase II trial of weekly docetaxel for advanced-stage non-small-cell lung cancer in elderly patients with significant comorbidity and/or poor performance status: The GFPC 02-02b study

CONTEXT

The objective of this study was to evaluate the feasibility and activity of weekly docetaxel monotherapy in frail elderly patients with advanced-stage non-small-cell lung cancer, selected on the basis of their precise age, general condition, and number of comorbid disorders (Charlson score).

METHODS

Analysis of the response rate, toxicity, quality of life, median survival and 1-year survival rates after 1-3 six-week cycles of docetaxel 30mg/m(2) weekly.

RESULTS

Fifty patients were enrolled and 42 were assessable. Five patients (10%, [3.7-22.6]) had objective responses, 14 (28%, [16.9-41.6]) had stable disease, and 23 (46%, [32.6-52.8]) progressed. The main grade 3-4 toxicity was fatigue (30%). Quality of life remained stable during treatment. The median survival time was 4.3 months, and the 1-year survival rate was 21.8%.

CONCLUSION

In frail elderly patients selected on the basis of their age, general condition and comorbidity, weekly docetaxel monotherapy has acceptable toxicity and does not negatively affect quality of life. In contrast, it has only moderate activity.

Results and Impact of Routine Assessment of Comorbidity in Elderly Patients with Non–Small-Cell Lung Cancer Aged > 80 Years

BACKGROUND

Elderly patients now represent a bigger proportion of patients with non-small-cell lung cancer (NSCLC). However, data from clinical trials are limited for this age group, and the elderly are often excluded from optimal treatment for several reasons, including comorbidity.

PATIENTS AND METHODS

We reviewed a 10-year experience on proven patients with NSCLC aged > 80 years; comorbidity was assessed using the Charlson Comorbidity index (CCI). The main objective was the impact of comorbidity on survival outcome.

RESULTS

Of 109 managed patients aged > 80 years, 74 patients had a proven diagnosis of NSCLC. Performance status was < 2 in 58 patients and TNM classification of malignant tumors was I-II, IIIA-IIIB, and IV in 18, 27, and 29 patients, respectively. Comorbidity was present for 49 patients. Charlson Comorbidity Index ranged from 4 to 12 with 31 patients having a CCI >or= 6. Sixteen patients received supportive care only, whereas 23 patients were operated on, 12 received radiation therapy, and 23 had chemotherapy. Eight grade 3/4 toxicities were reported (3 patients discontinued treatment). Multivariate analysis demonstrated a significant increase in the risk of death for patients with a poor Eastern Cooperative Oncology Group performance status (hazard ratio, 2.64; 95% confidence interval, 1.3-5.36; P = 0.007) and an advanced TNM stage (hazard ratio, 3.31; 95% confidence interval, 1.99-5.5; P < 0.00001). Although statistic significance was not reached, a difference in overall survival was shown between patients with a CCI < 6 and CCI >or= 6 (12.2 months vs. 8.2 months; P = 0.08).

CONCLUSION

These results support a role for the CCI as a routine means to assess comorbidity, because patients with fewer comorbidities tolerate and derive survival benefit of optimal NSCLC management. These findings must be confirmed in prospective studies.
