- Tested in people
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: A chemotherapy taken as a capsule. It is the P in the PCV combination used for some gliomas. See the glossary to lomustine: A chemotherapy you take as a capsule. You take it now and then, not every day. It lowers your blood counts weeks after a dose. That is why the doses are spaced out. See the glossary 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: A chemotherapy you take as a capsule. You take it now and then, not every day. It lowers your blood counts weeks after a dose. That is why the doses are spaced out. See the glossary alone with lomustine plus procarbazine: A chemotherapy taken as a capsule. It is the P in the PCV combination used for some gliomas. See the glossary after glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and 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: A chemotherapy you take as a capsule. You take it now and then, not every day. It lowers your blood counts weeks after a dose. That is why the doses are spaced out. See the glossary 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: A chemotherapy you take as a capsule. You take it now and then, not every day. It lowers your blood counts weeks after a dose. That is why the doses are spaced out. See the glossary on its own may be a fair choice if glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary comes back. Adding procarbazine: A chemotherapy taken as a capsule. It is the P in the PCV combination used for some gliomas. See the glossary 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: A chemotherapy you take as a capsule. You take it now and then, not every day. It lowers your blood counts weeks after a dose. That is why the doses are spaced out. See the glossary is a cure. glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and 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: A chemotherapy taken as a capsule. It is the P in the PCV combination used for some gliomas. See the glossary is wrong for every person. Your own plan is a talk to have with your doctor.
