Abstract

Objective:

To explore the correlation between the marital status and prognosis of patients with laryngeal squamous cell carcinoma (LSCC).

Study Design:

MPSM was adopted to minimize the maximum standardized average difference of the covariates among the four groups with different marital status.

Setting:

Multinomial propensity scores matching (MPSM) based on data from the surveillance, epidemiology, and end results (SEER) database.

Methods:

The Kaplan-Meier method and log-rank test were used to compare the survival outcomes of these groups with different marital status.

Results:

Totally, 16,981 LSCC patients (median [IQR] age 62 [55-69] years; 829 [76.41%] males) from 2004 to 2016 were included in this study. Among them, 9112 (53.66%) were married, 2708 (15.95%) divorced or separated, 1709 (10.06%) widowed, and 3452 (20.33%) single. After MPSM, the weights make the characteristics of four groups with different marital status sufficient balance. The Kaplan-Meier method and log-rank test showed widowed patients may lead to the highest mortality rate while married patients have a higher survival rate than the other three groups. Single and divorced or separated patients had no significant difference in the survival rate. In addition, multivariate analysis by controlling for confounding factors showed that in male, well-differentiated, and early stage patients, compared with married, unmarried was an independent risk factor for CSS (P < 0.05).

Conclusion:

Marital status showed a significant association with the survival status of LSCC patients. Importantly, the outcome of married patients was better, while widowed patients tended to have worse prognosis.

Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Comparing the Survival Analysis of Two or More Groups

Comparing the Survival Analysis of Two or More Groups

Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Assumptions of Survival Analysis

Assumptions of Survival Analysis

Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Kaplan-Meier Approach

Kaplan-Meier Approach

The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

The Mantel-Cox Log-Rank Test

The Mantel-Cox Log-Rank Test

The Mantel-Cox log-rank test is a widely used statistical method for comparing the survival distributions of two groups. It tests whether a statistically significant difference exists in survival times between the groups without assuming a specific distribution for the survival data, making it a non-parametric test. This flexibility makes the log-rank test particularly valuable in medical research and other fields where the timing of an event, such as death or disease recurrence, is of...

Truncation in Survival Analysis

Truncation in Survival Analysis

Truncation in survival analysis refers to the exclusion of individuals or events from the dataset based on specific criteria related to the time of the event. This exclusion can happen in two primary forms: left truncation and right truncation.
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...
