Abstract:

In this study, we examined the treatment and outcomes of pancreatic adenocarcinoma in New Mexico Native Americans (NA).

Methods:

A retrospective review of patients treated for pancreatic adenocarcinoma at a university cancer center from 2002-2016 comparing demographic characteristics, disease presentation, treatment, and outcomes among three main ethnic groups in New Mexico.

Results:

We identified 457 patients: 240 (52.5%) non-Hispanic Whites, 186 (40.7%) Hispanics, and 31 (6.8%) NA. Non-Hispanic Whites (OR 2.41; p=.026) and Hispanics (OR 2.37; p=.032) were more likely to receive or be offered chemotherapy than NA. More NA than non-Hispanic Whites died within one month of diagnosis (25.8% and 7.5%, respectively; p=.004). The NAs demonstrated a 26.2% one-year survival (CI 11.7-43.3), compared with 48.3% in non-Hispanic Whites (CI 40.9-55.2; p=.015).

Conclusion:

Significant disparities exist in the treatment and outcomes of pancreatic adenocarcinoma in New Mexico NA populations.

Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Survival Curves

Survival Curves

Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
The Kaplan-Meier estimator is the most common method for constructing survival curves. This...

Introduction To Survival Analysis

Introduction To Survival Analysis

Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...

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...

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...

Censoring Survival Data

Censoring Survival Data

Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...
