Summary
For anal cancer patients receiving chemoradiotherapy, only elevated serum alkaline phosphatase (ALP) and lactate dehydrogenase (LD) levels indicated a higher risk of distant metastases, not other common factors.
Area of Science:
- Oncology
- Clinical Medicine
Background:
- Squamous cell carcinoma of the anal canal is a rare malignancy.
- Combined chemoradiotherapy is a standard treatment modality.
- Identifying prognostic factors is crucial for patient management.
Purpose of the Study:
- To evaluate the prognostic significance of commonly recorded clinical and laboratory parameters in patients with anal squamous cell carcinoma.
- To determine if routine assessments can predict treatment outcomes and metastasis development.
Main Methods:
- Retrospective analysis of 77 patients with anal squamous cell carcinoma treated with combined chemoradiotherapy.
- Follow-up assessments included clinical evaluation and laboratory tests.
- Statistical correlation analysis was performed to identify prognostic factors.
Main Results:
- Commonly recorded parameters such as age, sex, performance status, tumor stage, and differentiation grade were not significant prognostic indicators.
- Most blood tests did not correlate with prognosis.
- Elevated serum alkaline phosphatase (ALP) and lactate dehydrogenase (LD) were identified as unfavorable prognostic factors.
- Serum ALP and LD levels significantly correlated with the development of distant metastases.
Conclusions:
- Serum alkaline phosphatase and lactate dehydrogenase are valuable prognostic markers for predicting distant metastasis in anal squamous cell carcinoma patients.
- Routine clinical and pathological parameters have limited prognostic value in this patient cohort.
- Further research may explore the role of these biomarkers in treatment stratification.
