This was tested in people. That is the most reliable kind of research we share.
Doctors looked back at records of patients who already had these drugs.
The short version
Adding procarbazine to lomustine did not help people live longer.
What was studied. Doctors at seven brain cancer centers in Germany looked back at old patient records. They compared lomustine alone with lomustine plus procarbazine after glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary came back.
What they found. Seventy-seven patients were in each group. The usual time lived after the cancer came back was 11.6 months with lomustine alone. It was 10.0 months with both drugs. The usual time before the cancer grew again was 5.1 months with lomustine alone and 3.7 months with both drugs.
What this means, and what it doesn't
What it could mean: Lomustine on its own may be a fair choice if glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary comes back. Adding procarbazine did not help people in this study. Two drugs can bring more side effects with no clear gain.
What it doesn't mean: This does not mean lomustine is a cure. glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary is still very hard to treat. This study looked back at records that were already there. That kind of study cannot prove what caused what. It also does not mean procarbazine is wrong for every person. Your own plan is a talk to have with your doctor.
