Unlabelled: 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.

Objective: Acute graft-vs-host disease (aGVHD) remains an important cause of morbidity after reduced-intensity conditioning (RIC) allogeneic transplantation (allo-SCT). It has been shown that antithymocyte globulin (ATG) dose infused during RIC is a major determinant for the likelihood of developing aGVHD. The ATG modulation on aGVHD is likely related to in vivo T-cell depletion., Patients and Methods: We therefore investigated the relationship between the cellular composition of the allograft and clinical outcome in 57 patients who received allogeneic peripheral blood stem cells from HLA-identical siblings following an ATG-based RIC., Results: In a multivariate analysis, the CD8+ T cell dose infused was the only parameter associated with the risk of aGVHD (p=0.031; RR=1.96; 95% CI, 1.1-3.6). When looking at the extremes, patients experiencing grade III-IV aGVHD received a median of 143 x 10(6)/kg CD8+ T cells, while patients without aGVHD received a median of 96 x 10(6)/kg CD8+ T cells (p=0.021). None of the different cell subtypes contained in the allograft was associated with a significant probability of developing chronic GVHD. Patients with grade II aGVHD who received an intermediate dose of CD8+ T cells (median, 111 x 10(6)/kg) had a significantly better overall survival in comparison to patients with grade 0-I or grade III-IV aGVHD (p=0.009)., Conclusion: In comparison to myeloablative allo-SCT, these results demonstrate that a cautious monitoring of the number of cells infused, at least in the context of ATG-based RIC, may represent an important predictive indicator of early transplant-related events and outcome after RIC allo-SCT.
