Hypothesis
Does the pleural effusion fluid of patients with metastatic spread contain scatter factor?
Conclusion
The study identified significant amounts of hepatocyte growth factor/scatter factor in the pleura of patients with metastatic spread.
Supporting Evidence
- Four out of eleven pleural effusion samples showed positive scattering activity.
- Two samples with high titres were further purified and identified as hepatocyte growth factor/scatter factor.
- Heat and trypsin treatment reduced the scattering activity, indicating it is protein-based.
Takeaway
The researchers found a special protein called scatter factor in the fluid from the lungs of some cancer patients, which might help cancer cells spread.
Methodology
Pleural effusion samples were collected and screened for scattering activity using MDCK cell colonies.
Limitations
The sample size is small, limiting the generalizability of the findings.
Participant Demographics
Patients with metastatic spread to the pleura and one case of primary pleural malignancy.
