Hypothesis
The study aims to find a correlation between the levels of expression of the genes for sensitivity to 5-FU (TS, TP, DPD) within the tumor and the clinical response observed after chemotherapy.
Conclusion
The study suggests that lower levels of expression of sensitivity genes correlate with better clinical responses to chemotherapy in patients with advanced pharyngo-laryngeal cancer.
Supporting Evidence
- The mean expression levels of TS, TP, and DPD were lower in the responder group compared to the non-responder group.
- Five patients had partial responses, one had a complete response, and three had disease progression after chemotherapy.
Takeaway
The study looks at how certain genes in tumors can help predict if chemotherapy will work for patients with throat cancer.
Methodology
This was a prospective genetic study assessing gene expression using quantitative RT-PCR on tumor biopsies and evaluating clinical response after chemotherapy.
Potential Biases
Potential bias due to the subjective nature of clinical assessments and the small, homogeneous sample.
Limitations
The study had a small sample size and only included male patients, which may limit the generalizability of the findings.
Participant Demographics
All participants were male, with a mean age of 58.5 years, presenting with operable epidermoid carcinoma of the larynx or hypopharynx.
