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...

Treatment Resistent Cancers

Treatment Resistent Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Background:

Colorectal cancer (CRC) is a prevalent malignancy in the UK.
Survival rates for CRC patients can differ significantly across healthcare centers.
District hospitals play a crucial role in managing CRC patient outcomes.

Purpose of the Study:

To report 5-year survival rates for colorectal cancer patients treated at a district hospital.
To investigate the impact of various patient and treatment-related factors on CRC survival.
To compare local CRC survival data with national benchmarks.

Main Methods:

Retrospective review of 405 colorectal cancer patients who received curative treatment between 2017-2019.
Kaplan-Meier method used to analyze survival rates.
Cox regression models employed to assess the relationship between survival time and influencing variables.

Main Results:

Overall 5-year survival rate was 59.3% (2-year survival: 78.5%).
Five-year survival rates by stage: Stage I (80.9%), Stage II (67.3%), Stage III (55%), Stage IV (10.9%).
Lower survival rates were observed in male patients, those with colon cancer, patients over 50, those without curative resection, and those receiving adjuvant therapy.

Conclusions:

The district hospital's CRC survival rates are comparable to other centers, considering local population demographics.
Patient age, tumor location, gender, curative resection status, and adjuvant therapy significantly affect colorectal cancer survival.
These findings highlight the importance of personalized treatment strategies and further research into disparities in CRC outcomes.
