Ongoing, gentler treatment given after the main course has shrunk the cancer, to hold it in check for as long as possible rather than to shrink it further.
Maintenance is standard in several settings: PARP inhibitors after platinum chemotherapy in ovarian cancer, pemetrexed or immunotherapy after induction chemotherapy in lung cancer, lenalidomide after transplant in myeloma, and rituximab in follicular lymphoma. The rationale is that the disease remaining after induction is small and slow-growing, so a tolerable long-term drug can delay progression by months or years, while the cost is cumulative side effects and expense during a period when the patient feels well. Trials of maintenance measure progression-free survival above all, and whether they extend overall survival is often debated.
Showing the molecule this term concerns: Olaparib.
The authors' conclusion is that ibrutinib-rituximab should be considered a new standard-of-care option for first-line treatment of older patients with mantle-cell lymphoma. The subgroup split means it is clearly better than R-CHOP and roughly equivalent to bendamustine-rituximab.
Twenty-eight extra months of progression-free survival, with no survival gain and a high rate of severe adverse events in both arms. It set up the two trials that followed: ECHO, which substituted a more selective inhibitor, and ENRICH, which removed the chemotherapy.
The number to give a patient deciding about maintenance: a median of six and a half extra years before the next treatment, and no difference in how long they live. Both halves belong in the conversation.
A clean example of a progression-free survival benefit that did not become a survival benefit. Lenalidomide maintenance did not become standard practice after this trial, and the figures are the reason.
One of the few maintenance strategies in lymphoma that improved overall survival rather than only progression-free survival, and the reason three years of rituximab became standard after autologous transplantation in mantle cell lymphoma.
The trial that made two years of rituximab maintenance a routine offer after first-line immunochemotherapy for follicular lymphoma with a high tumour burden.
