Outcomes of older patients with diffuse large B-cell lymphoma treated with R-CHOP: 10-year follow-up of the LNH03-6B trial.

ABSTRACT: The LNH03-6B trial was a phase 3 randomized trial evaluating the efficacy of first-line rituximab, cyclophosphamide, doxorubicine, vincristine and prednisone (R-CHOP) delivered every 2 weeks (R-CHOP14) or 3 weeks (R-CHOP21) in patients with diffuse large B-cell lymphoma (DLBCL) aged 60 to 80 years with an aaIPI (age-adjusted International Prognostic Index) score ≥1 (registered as NCT00144755). We implemented a prospective long-term follow-up program at the end of this trial. The primary endpoints were progression-free survival (PFS) and overall survival (OS). Relapse patterns, PFS and OS after the first progression (PFS2 and OS2) were secondary endpoints. LNH03-6B was registered with ClinicalTrials.gov #NCT00144755. In the LNH03-6B trial, 304 and 296 patients were assigned to receive 8 cycles of R-CHOP14 or R-CHOP21, respectively. Long-term follow-up data were investigated for 256 of 384 (67%) patients still alive at the primary analysis. With a median follow-up of 10.1 years, 213 patients progressed, and 140 patients died without progression. The 10-year PFS was 40.4% (95% confidence interval, 35.9-44.9). Ten-year OS was based on 302 deaths and estimated at 50% (43-56). Of the 213 patients, 105 (49%) progressed after second-line therapy, and 77 patients died without a second progression (36%). The 1-year PFS2 and 1-year OS2 were estimated at 37.9% (95% confidence interval, 31.4-44.5) and 55.8% (95% confidence interval, 48.8-62.2), respectively. Ten years after randomization, the outcomes of patients treated for DLBCL were similar according to PFS and OS between the RCHOP-14 and R-CHOP21 groups. Progression or relapse led to poor prognosis after second-line chemotherapy in the pre CAR-T-cell era. Novel approaches in first-line and alternative treatments in second-line treatments are warranted in this population.

Project description:Sotos syndrome is caused by a gene deletion with an autosomal dominant pattern of inheritance. Cerebral gigantism, hypotonia and joint hyperextensibility are characteristic features of this syndrome. A percentage of these patients develop progressive scoliosis early in life. In the literature, few studies on the evolution of scoliosis in Sotos syndrome have been published. We retrospectively evaluated eight patients diagnosed with Sotos syndrome and scoliosis treated at the Garrahan Children Hospital between 1988 and March 2009. Clinical charts and imaging studies were assessed. Eight patients (19%) presented with scoliosis and seven of them (87.5%) required surgical treatment. The mean follow-up was 9.5 years (range 3-18). Mean age at first consultation was 5.2 years (range 1.1-11.2). Mean Cobb angle for scoliosis at first consultation was 34.3° (range 20°-42°) and the mean Cobb angle for kyphosis was 45.6° (range 30°-90°). Mean age at surgery was 11.2 years (range 3.7-18.10). The surgical procedures performed were instrumented posterior arthrodesis, alone or combined with anterior arthrodesis, instrumented anterior arthrodesis, while one patient is currently in treatment with growing rods. Preoperative mean Cobb angle for scoliosis was 72.3° (range 54°-130°) and for kyphosis was 59.8° (range 30°-108°); postoperative mean Cobb angle for scoliosis was 45.5° (range 6°-90°) and for kyphosis was 40.2° (range 30°-80°). There were three early complications (pleural effusion in two cases and death due to sepsis in one) and two late complications (kyphosis above the instrumentation area and dislodgement of the proximal hooks). Incidence of scoliosis in Sotos syndrome is high and thus close monitoring of patients with Sotos syndrome during growth is important for early detection of this entity. Joint hyperextensibility and hypotonia that are characteristic of the syndrome should be considered at the moment of surgery to avoid short fusions.
