Year Outcome and Safety in Patients Treated With Immune Checkpoint Biology Diagrams Retrospective pattern-of-failure data in patients with non-small cell lung cancer (NSCLC) led to the initiation of two prospective randomized trials of local therapy plus systemic therapy versus local therapy alone [16, 17]. Both trials demonstrated that improved PFS could be achieved by treating established tumors present at baseline, but in Introduction: Despite remarkably improved outcomes with immune checkpoint inhibition, many patients with metastatic melanoma will eventually require further therapy. Chemotherapy has limited activity when used first-line but can alter the tumour microenvironment and does improve efficacy when used in combination with immunotherapy in lung cancer.
It has been approved as first- or second-line therapy in many cancer types. Unfortunately, a majority of immune checkpoint inhibitor recipients are refractory to the therapy.

J Clin Oncol 2025; DOI: 10.1200/JCO-24-02402. This review will focus on three major areas of cell cycle transition control, with particular attention to the alterations found in human cancer. These areas include the G1/S transition, where most cancerโrelated defects occur, the G2/M checkpoint and its activation in response to DNA damage, and the spindle checkpoint.

Immune checkpoint inhibitors (ICIs) block inhibitory pathways that tumour cells exploit to evade the immune system. They play a key role in the management of aggressive cancers, including non-small cell lung cancer, melanoma and Hodgkin's lymphoma. Despite their efficacy, ICIs can cause severe, potentially fatal, immune-related adverse events (irAEs), including multiorgan failure. Immune checkpoint inhibitors (ICIs), such as pembrolizumab and nivolumab, are associated with high response rates in patients with relapsed or refractory (R/R) classic Hodgkin lymphoma (cHL). 1, 2 Patients responding to ICI often undergo consolidation with an autologous 3 or allogeneic blood or marrow transplantation (BMT; alloBMT). 4, 5 alloBMT carries significant and well-recognized risks of Introduction. Immune system activation is an extremely effective anticancer therapy that has revolutionised oncological clinical practice over the last decade.1 The immune checkpoint inhibitors (ICIs) are a group of drugs that 'take the brakes' off the normal immune response and facilitate immunological, as opposed to traditional cytotoxic, anti-cancer effects.
