Background: No standard treatment is defined for elderly patients with small cell lung cancer (SCLC). Carboplatin and etoposide are highly active agents against SCLC. In this study, we evaluated the activity and toxicity of a combination of these two agents. Patients and methods: Thirty-four untreated patients with limited or extensive SCLC and median age of 73.9 years entered the study. Chemotherapy consisted of carboplatin i.v. on day 1 (AUC 5 using Calvert's formula) and etoposide 100 mg/m 2 given orally on days 1-5, every 4 weeks, and thoracic irradiation was given to limited disease patients after chemotherapy. Results: The overall response rates was 59% (95% CI: 43-76). The median survival for all patients was 37 weeks (range 3-76 weeks). The toxicity was mainly haematological with grade 3-4 neutropenia in 59% of courses, febrile neutropenia in 15% of courses, and toxic death in 9% of patients. Conclusion: The results of this regimen are disappointing with worse response and survival, and more haematological toxicity than expected and previously reported, despite the use of Calvert's formula. Possible explanations are the use of etoposide per os rather than i.v., the frequent comorbidities of older patients and the inclusion of patients with poor prognosis factors.
Role of Chemoradiotherapy in Elderly Patients With Limited-Stage Small-Cell Lung Cancer
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2015
To investigate outcomes for elderly patients treated with chemotherapy (CT) alone versus chemoradiotherapy (CRT) in the modern era by using a large national database. Elderly patients (age ≥ 70 years) with limited-stage small-cell lung cancer clinical stage I to III who received CT or CRT were identified in the National Cancer Data Base between 2003 and 2011. Hierarchical mixed-effects logistic regression with clustering by reporting facility was performed to identify factors associated with treatment selection. Overall survival (OS) of patients receiving CT versus CRT was compared by using the log-rank test, Cox proportional hazards regression, and propensity score matching. A total of 8,637 patients were identified, among whom 3,775 (43.7%) received CT and 4,862 (56.3%) received CRT. The odds of receiving CRT decreased with increasing age, clinical stage III disease, female sex, and the presence of medical comorbidities (all P < .01). Use of CRT was associated with increased OS...
Treatment of small cell lung cancer in the elderly
Hematology/Oncology Clinics of North America, 2004
Small cell lung cancer (SCLC) accounts for approximately 20% of lung carcinomas. Chemotherapy is the cornerstone of treatment for SCLC. In limited disease, the median survival time is about 12-16 months, with a 4%-5% long-term survival rate; in extensive disease the median survival time is 7-11 months. More than 50% of lung cancer patients are diagnosed when they are over the age of 65, and about 30% are over 70. Elderly patients tolerate chemotherapy poorly compared with their younger counterparts, because of agerelated progressive reductions in organ function and comorbidities. The standard therapy for limited disease is combined chemoradiotherapy, followed by prophylactic brain irradiation for patients achieving complete responses. In the elderly, the addition of radiotherapy to chemotherapy must be carefully evaluated, considering the slight survival benefit and potential for substantial toxicity incurred with this treatment. The best approach is to design clinical trials that specifically include geriatric assessment to develop active and well-tolerated chemotherapy regimens for elderly SCLC patients. Survival improvement for SCLC patients requires a better understanding of tumor biology and the subsequent development of novel therapeutic strategies. Several targeted agents have been introduced into clinical trials in SCLC, but a minority of these new agents offers a promise of improved outcomes, and negative results are reported more commonly than positive ones. This review focuses on the main issues in the treatment of elderly SCLC patients. The Oncologist 2005;10:399-411
Treatment of small-cell lung cancer in elderly patients
Cancer, 2010
Small-cell lung cancer (SCLC) represents 15% to 20% of all lung carcinomas. Approximately 30% to 40% of these cases are diagnosed in patients older than 70 years of age. Staging of SCLC classifies patients as having either limited or extensive-stage disease. The standard treatment for limited-stage disease is platinum-based chemotherapy, combined with external-beam thoracic radiotherapy, whereas platinum-based regimens alone represent the standard of care for extensive-stage disease. In the elderly population, treatment of SCLC is more challenging given the decline in physiological organ reserve and the presence of comorbidities. The majority of data are drawn from retrospective studies, which are likely to suffer from selection bias. However, limited prospective data are available to guide treatment decisions in that special population. Nonetheless, these data demonstrate that standard approaches are feasible in carefully selected elderly patients. The purpose of this article is to review the currently available evidence on treatment of SCLC in patients older than 65-70 years of age.

Background For small-cell lung cancer confined to one hemithorax (limited small-cell lung cancer), thoracic radiotherapy improves survival, but the best ways of integrating chemotherapy and thoracic radiotherapy remain unsettled. Twice-daily accelerated thoracic radiotherapy has potential advantages over once-daily radiotherapy. Methods We studied 417 patients with limited small-cell lung cancer. All the patients received four 21-day cycles of cisplatin plus etoposide. We randomly assigned these patients to receive a total of 45 Gy of concurrent thoracic radiotherapy, given either twice daily over a three-week period or once daily over a period of five weeks. Results Twice-daily treatment beginning with the first cycle of chemotherapy significantly improved survival as compared with concurrent once-daily radiotherapy (P=0.04 by the log-rank test). After a median follow-up of almost 8 years, the median survival was 19 months for the once-daily group and 23 months for the twice-daily group. The survival rates for patients receiving once-daily radiotherapy were 41 percent at two years and 16 percent at five years. For patients receiving twice-daily radiotherapy, the survival rates were 47 percent at two years and 26 percent at five years. Grade 3 esophagitis was significantly more frequent with twice-daily thoracic radiotherapy, occurring in 27 percent of patients, as compared with 11 percent in the once-daily group (P<0.001). Conclusions Four cycles of cisplatin plus etoposide and a course of radiotherapy (45 Gy, given either once or twice daily) beginning with cycle 1 of the chemotherapy resulted in overall two-and five-year survival rates of 44 percent and 23 percent, a considerable improvement in survival rates over previous results in patients with limited small-cell lung cancer.

Between 1978 and 1983, 72 patients aged 70 years or older (median 72, range 70-80) were treated for biopsy-proven, small cell lung cancer (SCLC). Intercurrent disorders were common, including ischaemic heart disease, peripheral vascular disease, chronic airflow limitation and second malignancies. 26 patients (36%) had limited extent of disease, and 46 (64%) had extensive disease. "Intensive" chemotherapy incorporating vincristine, cyclophosphamide and doxorubicin (OCA regimen) was administered to 32 patients [complete response (CR) + partial response (PR) = 84%]; less rigorous regimens (e.g. single agent chemotherapy, planned dose reductions, radiotherapy only) were used in 34 cases (CR + PR = 52%); and 6 received no active treatment. In the intensively treated group, there were 3 treatment-related deaths and 26 episodes of WHO grade 3-4 toxicity. In the less intensively treated group, there were no treatment-induced deaths and only 1 episode of severe toxicity. The overal...

BACKGROUND: Platinum and etoposide with thoracic radiation followed by prophylactic cranial irradiation constitute the standard treatment for limited-stage small cell lung cancer (LS-SCLC). Many patients with LS-SCLC are elderly with comorbidities. METHODS: Individual patient data were collected from 11 phase 2 or 3 trials for LS-SCLC conducted by the National Clinical Trials Network and activated from 1990 to 2010. The primary endpoint was overall survival (OS); the secondary endpoints were progression-free survival (PFS), the rate of severe adverse events, and off-treatment reasons. The outcomes were compared for patients 70 years old or older (elderly patients) and patients younger than 70 years (younger patients). RESULTS: Individual patient data from 1049 younger patients (81%) and 254 elderly patients (19%) were analyzed. In the multivariate model, elderly patients, in comparison with younger patients, had worse OS (hazard ratio [HR], 1.38; 95% confidence interval [CI], 1.18-1.63; median OS for elderly patients, 17.8 months; OS for younger patients, 23.5 months) and worse PFS (HR, 1.19; 95% CI, 1.03-1.39; median PFS for elderly patients, 10.6 months; median PFS for younger patients, 12.3 months). Elderly patients, in comparison with younger patients, experienced more grade 5 adverse events (8% vs 3%; P < .01) and more grade 3 or higher dyspnea (11% vs 7%; P = .03) but less grade 3 or higher esophagitis/ dysphagia (14% vs 19%; P = .04) and less grade 3 or higher vomiting (11% vs 17%; P = .01). Elderly patients completed treatment less often, discontinued treatment because of adverse events and patient refusal more frequently, and died during treatment more frequently. CONCLUSIONS: Elderly patients with LS-SCLC have worse PFS and OS and more difficulty in tolerating therapy. Future trials should incorporate assessments of elderly patients, novel monitoring of adverse events, and more tolerable radiation and systemic therapies.
