Insights
This study on chronic lymphocytic leukemia (CLL) found that while survival rates were 64% with a mean of 38.5 months, females had a higher overall survival than males. Clinical features like lymphadenopathy were prevalent.
Area of Science:
- Hematology
- Oncology
- Epidemiology
Background:
- Chronic lymphocytic leukemia (CLL) is a prevalent leukemia in Western adults, yet less common in Asia.
- Key patient complaints include immune hemolytic anemia, Evan's syndrome, lymphadenopathy, organomegaly, and B symptoms.
Purpose of the Study:
- To evaluate correlations between sex, age, and overall survival in 109 chronic lymphocytic leukemia (CLL) patients.
- To analyze clinical features and disease staging in a cohort of Iranian CLL patients.
Main Methods:
- Retrospective analysis of 109 CLL patients hospitalized between 2006 and 2014.
- Statistical analysis of sex and age using IBM SPSS19.
- Overall survival plotted using Kaplan-Meier and Log-rank tests (Graph Pad Prism 5).
Main Results:
- The mean age at diagnosis was 60.73 years, with 59.6% of patients being male.
- Overall survival rate was 64%, with a mean survival of 38.5 months.
- Lymphadenopathy (38.7%) and organomegaly (34%) were the most frequent clinical features; females showed higher overall survival than males.
Conclusions:
- No significant relationship was found between sex and age in this cohort.
- Overall survival rates in females were higher compared to males.
- Findings contrast with Asian prevalence data, which indicate higher CLL incidence in males over 60.
Abstract:
Chronic lymphocytic leukemia (CLL)is the most common leukemia in adults in Western countries but is relatively rare in Asia. Immune hemolytic anemia, Evan's syndrome, lymphadenopathy, organomegaly and B symptoms are the main complaints of patients in CLL. The present retrospective analysis evaluated a group of 109 patients with CLL over a 9-year period, studying correlations between sex, age and overall survival. The patients were hospitalized in the Clinic of Hematology and Oncology, Kermanshah, Iran, between 2006 and 2014. Data analysis for sex and age was performed using IBM SPSS19 and overall survival was plotted by Kaplan- Meier plot, Log-rank test in Graph Pad prism 5 Software for five-year periods. The mean age of diagnosis for CLL patients was 60.73 years, 59.6% male. Survival rate patients was 64% and mean overall survival was 38.5 months. In the Rai system, fourteen patients (12.8%) had stage III and twenty eight patients (25.7%) had stage IV. Most frequent clinical features in patients with CLL were lymphadenopathy (38.7%) and organomegaly (34%), respectively. There is not relationship between sex and age in patients but overall survival rate in females was higher than in males. In Asian countries, CLL is more in male and in age above 60 years. Complaints about lymphadenopathy and virus infection are prevalent.
