Cll Survival Rate By Stage – At age 60, deletion of chromosome 17p (17p-) and high β2-MG were associated with worse OS. Patients with three of these negative outcomes had worse outcomes than patients with only one or two. Patients with 17p- had a lower ORR (P = 0.008) and shorter OS (P = 0.001) than those without 17p-. Treatment based on Rituximab (R) was able to overcome the malignancy associated with 17p-. Furthermore, the addition of R to fludarabine (F) and cyclophosphamide (C) treatment significantly improved OS (P=0.012) compared to FC alone in younger patients. However, there was no significant effect for older patients (P = 0.07). Of course the patient’s age plays an important role in their response to treatment and survival.
Although people with primary lung cancer (CLL) have a life expectancy of more than 10 years, those with chronic or advanced disease (Binet stages B and C) have a life expectancy of 2-7 years (1). Most patients are asymptomatic and can live for decades without treatment, while others develop a severe form of the disease that may lead to death or complications related to treatment immediately after diagnosis. However, most of the research on CLL comes from Western countries, and there are few studies that report results on Chinese patients.
Cll Survival Rate By Stage
For more than 30 years, CLL has been treated with various chemotherapy drugs, including the drug chlorambucil (Ch). In the last decade, combining purine analogs with alkylating drugs, especially fludarabine (F) and cyclophosphamide (C), has improved the clinical response rate and complete remission. (CR) and overall survival (2). In addition, the use of rituximab (R) has improved the efficacy of CLL treatment, with overall response rates of 40-70% (3-5). Since this trial included young patients with good performance and no serious disease, the results of these studies are very important for the treatment of Western patients with CLL. The benefit of anti-CD20 antibodies in Asian patients with CLL remains uncertain. The main purpose of our study is to investigate the clinical characteristics of CLL patients in China and to evaluate the effect of R treatment.
Major Differences Between Leukemia And Lymphoma
Between January 2002 and December 2011, 210 patients with CLL were treated at our institution. History, physical findings and laboratory data of patients were collected for analysis. The diagnostic criteria for CLL are as follows: i) Persistent lymphocytosis of >5 × 109/l for ≥3 months; ii) small to medium lymphocytes without nucleoli; iii) no hair cell formation; iv) CD5+, CD19+ and CD10− immunophenotypes; and v) no D1 cycling exposure. Study protocols were reviewed and approved by the Union Hospital of Fujian Medical University Review Board.
Serum and heparinized blood samples were obtained from all patients before treatment. Serum lactate dehydrogenase (LDH) and serum β2-microglobulin (β2-MG) were assessed by radioimmunoassay.
To determine VH gene status, reverse transcription-polymerase chain reaction (RT-PCR) was performed using VH primers (6). Amplified PCR products were purified and sequenced correctly using a sequencing kit (Applied Biosystems, Carlsbad, CA, USA). Mutation status was determined by comparison with the consensus germline sequence according to IgBlast (www.ncbi.nlm.nih.gov/igblast) and IMGT/V-QUEST (http://www.imgt.org) . We defined a gene as ‘difference’ when the sequence deviated ≥2% from the consensus sequence.

Flow cytometry analysis in this study was performed on a FACSCalibur flow cytometer (BD Biosciences, Franklin Lakes, NJ, USA). The expression of CD38 was analyzed by 3-color immunofluorescence ( 7 ) and detection of ZAP-70 was performed according to methods described previously ( 8 ). A cutoff point of 30% positive cells was chosen to distinguish CD38− from CD38+ CLL. A cutoff point of 20% was used to separate ZAP-70− from ZAP-70+ CLL.
In situ hybridization (FISH) was performed to identify trisomy 12 and chromosome deletion at 13q14.3, 11q22.3 and 17p13.1 loci. A chromosome 12-specific α-satellite probe was used to identify trisomy 12. To detect the 13q14.3 deletion, a locus-specific probe (LSI D13D25) was combined with a 13q34 telomeric probe as an internal control for the nullisomy. A combination of two colors using appropriate centromere-specific probes and sequence-specific probes for the ATM (LSI ATM) and TP53 (LSI P53) loci was performed to identify deletions. 11q22.3 and 17p13.1. . All probes were purchased from Vysis (Abbott, Shanghai, China) and FISH procedures were performed according to the manufacturer’s instructions. For each fusion, ≥200 interphase nuclei were examined. Patients were divided into low (13q14.3 deletion and normal), medium- (trisomy 12) and high- (11q22.3 and 17p13.1 deletion) risk groups for the latter phase. from
The treatment consisted of six 28-day sessions of intravenous F at 25 mg/m2 per day and C at 250 mg/m2 per day on the first three days of each treatment course, with or without R at dose of 375 mg / m2 day. 0 for each course. Ch was initially administered at 0.4 mg/kg body weight (BW) once a day and increased by 0.1 mg/kg at each treatment course to 0.8 mg/kg BW if treatment was satisfactory. Maintenance therapy is performed with two cycles of the first course of treatment after CR is achieved.
Driving Out Chronic Lymphocytic Leukemia With Car T Cells
Clinical data are presented using descriptive statistics. The χ2 test was used to compare clinical characteristics between groups. Overall survival (OS) was defined as the time between the date of diagnosis and the date of the last objective or death from any cause. For univariate survival analysis, the Kaplan-Meier method was used for incomplete observations. Survival estimates were compared using the log-rank test. Multivariate analysis of factors affecting OS was performed using the Cox proportional-hamzards regression method. P < 0.05 was considered to indicate a statistical difference. All tests were two-tailed with a multiple significance level α = 5%.
Between January 2002 and December 2011, 210 patients with CLL from a single center in China were enrolled in this study and followed for survival. The main clinical characteristics of the 210 patients in this study are shown in Table I. The median follow-up for the entire group was 68 months (range, 4-110 months). There were 95 men and 115 women in this study, their ages at enrollment ranged from 35-92 years and the average age was 60.2 years (Figure 1). Immunophenotypic data, available in 202 of 210 patients, showed that all cases of leukemia were CD19 +, 196/202 were CD5 +, 188/202 were CD20 + [61/188 i reported (+) and 127/188 reported (++) ] and 200/202 were CD23+. All cases were confirmed to be B-cell type. At the time of enrollment, 53 patients had stage A, 120 had stage B and 37 had stage C according to the Binet system.

And treatment without R was an independent predictor of worse OS in younger patients in multivariate analysis. Binet C stage and elevated β2-MG are independent predictors of OS in elderly patients.

Overall response rates [ORR, CR + partial remission (PR)] were significantly different between treatment regimens (P 60 years (P = 0.112).
The most common adverse reactions resulting from R or F treatment in this study were fatigue, skin sensitization, hematological toxicity and GI reactions (nausea, vomiting and diarrhea). There have been ten reports of cancer lysis syndrome, all in patients who received their first cycle of chemotherapy. Neutropenia was observed in 25% of patients, including grade 3 or 4 in 14% of patients, and thrombocytopenia was observed in 9% of patients. During maintenance therapy, 54% of patients had low Ig serum levels and 47 patients experienced grade 3 or 4 infections, including 26 patients with pneumonia, 10 to appendicitis, 6 cases of myositis and 5 of herpes zoster. Hepatitis B virus was activated in 10% (21 cases) of patients after R-treatment. Acute infection received particular attention because it is the main cause of morbidity and mortality in CLL patients. Of note, 39 patients treated with F, C and R developed grade 3 and 4 disease, whereas, only eight patients who received other treatments (including Ch) died. at level 3 and level 4. 4.

The median OS of the entire cohort was 67 months (Figure 1). Univariate analysis showed that age >60 years, chromosome 17p deletion (17p-) and high levels of β2-MG were associated with worse survival. Patients with 17p – had a lower ORR (40 vs. 72%; P = 0.008; Table I) and a shorter OS (33 vs. 64 months; P < 0.0001; Figure 2) than patients without 17p-.
