Treatment and survival of patients with small-cell lung cancer: small steps forward, but not for patients >80.
ABSTRACT Seventy-five percent of newly diagnosed patients with small-cell lung cancer (SCLC) are aged 60+ and quite a few are treated less aggressively because of fear of toxic effects. We described trends in treatment and survival of unselected SCLC patients.
For the present study, all 13,007 SCLC patients aged 60+ diagnosed in The Netherlands from 1997 to 2007 were included.
Among patients with limited disease, the proportion receiving chemoradiation increased from 35% to almost 60% for those aged 60-69, from 28% to 48% in age group 70-74, from 17% to 33% in age group 75-79, but remained <10% for those aged 80+. Among patients with extensive disease, the proportion receiving chemotherapy (CT) decreased from 81% of patients aged 60-64 to 23% of those aged 85+, without substantial changes over time. Survival has only improved for patients <80 years.
CT (+radiotherapy) has improved survival for unselected SCLC patients <80. A better understanding of the impact of frailty on completion of treatment and toxic effects among patients aged 80+ would enable the treating physician to anticipate toxic effects better and to discuss risks and benefits of treatment with the patient.

ABSTRACT: Cytotoxic therapy appears to have improved short-term survival for patients with small-cell lung cancer, but little is known about the results for unselected patients and trends in long-term survival. One thousand seven hundred ninety-six patients with small-cell lung cancer diagnosed between 1975 and 1994 in southeastern Netherlands. We studied treatment policy for and survival of unselected patients since 1975, when cytotoxic therapy emerged. The proportion patients receiving chemotherapy, with or without irradiation, almost tripled from 30% to 82% for patients younger than 70 years of age and from 15% to 56% for those over 70, whereas the proportion receiving only radiotherapy decreased from 36% to 5% in both age groups. The short-term (< 2 year) survival rate improved markedly between 1975 and 1989, especially for patients younger than 70 (median survival increased from five to 10 months). Two-year survival remained poor (8%). Two percent of all patients younger than 70 years at diagnosis survived for at least eight years, but these patients still represent an excess five-year mortality of 39%. In southeastern Netherlands short-term survival of patients with small-cell lung cancer improved markedly up to the end of the 1980s, but a major impact on cure rates has not been achieved.Annals of Oncology 05/1998; 9(5):543-7. · 7.38 Impact Factor

ABSTRACT: Combination chemotherapy with irinotecan and cisplatin is one of the standard treatments for patients with small-cell lung cancer (SCLC). In elderly patients, however, its efficacy and toxicity has not been well documented. In this Phase II study, we assessed the efficacy and toxicity of combination chemotherapy with irinotecan and cisplatin and examined whether advanced age compromises it in elderly patients with previously untreated extensive-disease small-cell lung cancer (ED-SCLC). In this study, 46 previously untreated elderly patients (65 years or older) with ED-SCLC were given combination chemotherapy consisting of irinotecan 60 mg/m(2) on days 1, 8 and 15 and cisplatin 60 mg/m(2) on day 1. The treatment was repeated every 4 weeks until patients completed the maximum six cycles. Patients consisted of 37 men and 9 women, whose median age was 70 years (range 65-81 years). A complete response and a partial response were observed in 19.6% (9/46) and 56.5% (26/46), respectively. The overall response rate was 76.1% (95% C.I; 63.8-88.4%). The overall median survival was 10.4 months (range 7.6-13.2 months). The median progression-free survival was 8.32 months (range 6.8-9.8 months). Major toxicities included neutropenia (grade 3-4, 58.7%), leukopenia (grade 3-4, 49.9%), infection (grade 3-4, 39.1%) and diarrhea (grade 3-4, 30.4%). Incidence of febrile neutropenia was significantly higher in patients with ECOG performance status 2-3 compared with ECOG performance status 0-1 (70.4% vs. 5.2%; p<0.001). There were two treatment related deaths in patients ECOG performance status 3. Our results indicate that combination chemotherapy with irinotecan and cisplatin is an effective treatment for elderly patients with ED-SCLC who have good ECOG performance status and physicians should be aware of the mortality and morbidity due to myelosuppression following this treatment in elderly ED-SCLC patients with poor ECOG performance status.Lung Cancer 02/2008; 61(2):220-6. · 3.39 Impact Factor

ABSTRACT: Studies have documented the underrepresentation of women and blacks in clinical trials, and their recruitment is now federally mandated. However, little is known about the level of participation of elderly patients. We determined the rates of enrollment of patients 65 years of age or older in trials of treatment for cancer. We analyzed data on 16,396 patients consecutively enrolled in 164 Southwest Oncology Group treatment trials between 1993 and 1996 according to sex, race (black or white), and age under 65 years or 65 or older. These rates were compared with the corresponding rates in the general population of patients with cancer, derived from the 1990 U.S. Census and from the National Cancer Institute's Surveillance, Epidemiology, and End Results Program for the period from 1992 through 1994. Fifteen types of cancer were included in the analysis. The overall proportions of women and blacks enrolled in Southwest Oncology Group trials were similar to or the same as the estimated proportions in the U.S. population of patients with cancer (women, 41 percent and 43 percent; blacks, 10 percent and 10 percent, respectively). In contrast, patients 65 years of age or older were underrepresented overall (25 percent vs. 63 percent, P<0.001) and in trials involving all 15 types of cancer except lymphoma. The underrepresentation was particularly notable in trials of treatment for breast cancer (9 percent vs. 49 percent, P<0.001). The findings were similar when data on patients who were 70 years of age or older were analyzed, when 15 trials that excluded older patients were eliminated from the analysis, and when community-based enrollment was analyzed separately from enrollment at academic centers. There is substantial underrepresentation of patients 65 years of age or older in studies of treatment for cancer. The reasons should be clarified, and policies adopted to correct this underrepresentation.New England Journal of Medicine 12/1999; 341(27):2061-7. · 51.66 Impact Factor
