How Do Elderly Poor Prognosis Patients Tolerate Palliative Concurrent Chemoradiotherapy for Locally Advanced Non–Small-Cell Lung Cancer Stage III? A Subset Analysis From a Clinical Phase III Trial

AbstractBackgroundIn a phase III trial of patients with unresectable, locally advanced, stage III non–small-cell lung cancer (NSCLC) with a poor prognosis, palliative concurrent chemoradiotherapy (CRT) provided a significantly better outcome than chemotherapy alone, except among performance status (PS) 2 patients. In the present subgroup analysis, we evaluated the effect on patients aged ≥ 70 years (42% of all included) compared with patients aged < 70 years enrolled in the trial.Patients and MethodsAll patients received 4 courses of intravenous carboplatin and oral vinorelbine. The experimental arm also received radiotherapy (42 Gy in 15 fractions). The included patients were required to have large tumors (> 8 cm), weight loss (> 10% within the previous 6 months) and/or PS 2.ResultsThe overall survival was increased among the CRT patients in both age groups, but the difference was significant only in patients aged < 70 years (median survival, 14.8 vs. 9.7 months; P = .001; age ≥ 70 years, median survival, 10.2 vs. 9.1 months; P = .09). Patients aged ≥ 70 years experienced better preserved health-related quality of life (QOL) and significantly less hematologic toxicity. The 2- and 3-year survival was significantly increased in both age groups receiving CRT.ConclusionElderly patients aged ≥ 70 years with unresectable, stage III, locally advanced, NSLCL and a poor prognosis can tolerate CRT with the doses adjusted to age and palliative intent. These results indicate that CRT can provide both survival and QOL benefits in elderly patients, except for those with PS 2 or worse. The male predominance in the ≥ 70-year-age group and the reduced chemotherapy intensity for the patients aged > 75 years might explain the lack of significant survival improvement among those patients aged ≥ 70 years

Does chemotherapy improve Quality of Life in NSCLC PS 2?

Introduction Nearly 40% of patients with advanced NSCLC are in performance status (PS) 2. These patients have a shorter life expectancy than PS 0/1 patients and they are underrepresented in clinical trials. Data on how platinum-based combination chemotherapy affects Health Related Quality of Life (HRQOL) of patients with PS 2 are scarce and the treatment of this important group of patients is controversial. Methods A national multicenter phase III study on platinum based chemotherapy to 432 advanced NSCLC patients included 123 patients with PS 2. To explore the treatment impact on HRQOL, the development of HRQOL during the first nine weeks were compared between PS 2 and PS 0/1 patients. We used the EORTC QLQ-C30 and QLQ-LC13 questionnaires. Standardized area under the curve for all HRQOL items, and HRQOL responses classified as better, stable or worse, were compared between the groups. Results Whereas the demographic data at baseline were well balanced between the groups, the PS 2 patients had significantly worse function and more severe symptoms than the PS 0/1 patients. In response to combination chemotherapy, the PS 2 patients had a more profound improvement of global QOL, cognitive function, fatigue, dyspnea, sleeping problems and appetite loss in comparison to the PS 0/1 group. Conclusions PS 2 NSCLC patients seem to achieve valuable HRQOL benefits from platinum-based combination therapy. Prospective clinical studies with predefined HRQOL outcomes in PS 2 patients are needed to confirm these findings

Randomized phase II trial comparing twice daily hyperfractionated with once daily hypofractionated thoracic radiotherapy in limited disease small cell lung cancer

BACKGROUND: Concurrent chemotherapy and thoracic radiotherapy (TRT) is recommended for limited disease small cell lung cancer (LD SCLC). Twice daily TRT is well documented, but not universally implemented - probably mainly due to inconvenience and concerns about toxicity. A schedule of three-week hypofractionated TRT is a commonly used alternative. This is the first randomized trial comparing twice daily and hypofractionated TRT in LD SCLC. MATERIAL AND METHODS: Patients received four courses of cisplatin/etoposide (PE) and were randomized to TRT of 42 Gy in 15 fractions (once daily, OD) or 45 Gy in 30 fractions (twice daily, BID) between the second and third PE course. Good responders received prophylactic cranial irradiation of 30 Gy in 15 fractions. RESULTS: 157 patients were enrolled between May 2005 and January 2011 (OD: n = 84, BID: n = 73). Median age was 63 years, 52% were men, 84% had performance status 0-1, 72% had stage III disease and 11% non-malignant pleural effusion. The treatment arms were well balanced. The response rates were similar (OD: 92%, BID: 88%; p = 0.41), but more BID patients achieved a complete response (OD: 13%, BID: 33%; p = 0.003). There was no difference in one-year progression-free survival (PFS) (OD: 45%, BID: 49%; p = 0.61) or median PFS (OD: 10.2 months, BID: 11.4 months; p = 0.93). The median overall survival in the BID arm was 6.3 months longer (OD: 18.8 months, BID: 25.1 months; p = 0.61). There were no differences in grade 3-4 esophagitis (OD: 31%, BID: 33%, p = 0.80) or pneumonitis (OD: 2%, BID: 3%, p = 1.0). Patients on the BID arm reported slightly more dysphagia at the end of the TRT. CONCLUSION: There was no difference in severe toxicity between the two TRT schedules. The twice daily schedule resulted in significantly more complete responses and a numerically longer median overall survival, but no firm conclusions about efficacy could be drawn from this phase II trial
