For the first time a new drug has beaten pembrolizumab, the global first-line standard, in a randomised lung cancer trial, and it did so by combining checkpoint blockade with anti-angiogenesis in one molecule. For patients outside China nothing changes yet: the drug is not approved in the West, the trial was single-country, and survival benefit has not been shown. If confirmed in the global HARMONi-3 and HARMONi-7 trials, PD-1 x VEGF bispecifics could replace PD-1 antibodies as the immunotherapy backbone.

IMerge validated telomerase as a drug target in cancer, decades after its discovery, and gave a second-line option for MDS patients whose anaemia no longer responds to erythropoietin or luspatercept. The hint of clonal reduction is what makes the drug interesting beyond transfusion counts. Cytopenias require close monitoring in the first cycles.

For the first time a randomised trial suggests that a vaccine tailored to an individual's tumour can reduce relapse when combined with immunotherapy, which is a proof of concept for a field that had failed for decades. Nothing changes for patients yet: the trial was small, the confidence interval crossed one, and the phase 3 trial in melanoma (and parallel trials in lung and other cancers) must confirm it. If it does, personalised mRNA vaccines could become a routine adjunct to checkpoint inhibitors after surgery.

Women with locally advanced cervical cancer that is node-positive or stage III-IVA should now be offered pembrolizumab alongside and after chemoradiotherapy, which improves the chance of cure. The result matters most in countries where cervical cancer is common but immunotherapy access is poorest, so its global impact depends on pricing and health-system capacity. It does not apply to early-stage disease treated with surgery or to lower-risk locally advanced disease without nodal involvement.

Patients newly diagnosed with an advanced grade 2 or 3 neuroendocrine tumour of the gut or pancreas that shows somatostatin receptors on imaging can now receive lutetium dotatate as their first treatment, gaining more than a year of additional disease control and a much higher chance of tumour shrinkage. It does not settle whether radioligand therapy is better than other first-line options such as capecitabine-temozolomide or everolimus, and long-term marrow safety with earlier use needs surveillance.

Afami-cel showed that T cells can be redirected against an intracellular cancer antigen, something CAR-T cannot do, and produced meaningful responses in a rare sarcoma with few options. It opens a path to TCR-T against other shared antigens and neoantigens. Restriction to one HLA type and one antigen, plus complex manufacturing, means it will help a small, defined group.

Patients with advanced synovial sarcoma, a rare cancer of young adults with few effective drugs, now have an approved cell therapy that produces responses lasting about a year in a substantial minority, if their tissue type and tumour antigen match. It proves that engineered T cells can work against a solid tumour when a good target is present, which had been elusive. It is not a cure for most, requires specialised centres, and only a minority of patients are eligible.

Patients with KRAS G12C lung cancer that has progressed after chemo-immunotherapy can take an oral KRAS inhibitor instead of docetaxel and gain a somewhat longer time to progression with fewer severe side effects, but should understand that most tumours become resistant within a year and that survival is not improved. KRAS G12C testing is worthwhile, but first-generation inhibitors are a step rather than a cure; combinations and next-generation inhibitors are the active research fronts.

COMMANDS moved luspatercept from second line (after ESA failure, MEDALIST trial) to first line, offering transfusion-dependent lower-risk MDS patients a better chance of transfusion freedom from the start. It changed guidelines and labels in 2023. Erythropoietin remains a reasonable and cheaper option for patients without ring sideroblasts or with low transfusion burden.

MOMENTUM addressed the biggest gap left by ruxolitinib: patients whose anaemia makes standard JAK inhibition hard to give. Momelotinib is now the preferred option for anaemic, previously treated myelofibrosis and is being adopted in first line for anaemic patients. The absolute symptom benefit is modest and durable disease modification has not been shown.

For fit patients with newly diagnosed metastatic pancreatic cancer, a FOLFIRINOX-type regimen is now proven to be better than gemcitabine plus nab-paclitaxel, settling a long-standing debate. The absolute gain is about two months of median survival, and the regimen is more toxic for the gut. Whether liposomal irinotecan adds anything over conventional irinotecan (standard FOLFIRINOX) has never been tested head-to-head.

A multi-cancer blood test can be run in ordinary clinics, and most positive results can be resolved with imaging. But six in ten positives are false alarms that take months to resolve, and the test misses most cancers. Whether it reduces late-stage cancer or deaths is unknown; that requires randomised trials.

QuANTUM-First gave FLT3-ITD AML patients a second front-line targeted option and showed that continuing a FLT3 inhibitor as long-term maintenance, including after transplant, pays off. Quizartinib was approved for this indication in 2023. Head-to-head data against midostaurin are lacking, and the design leaves open how much of the benefit came from maintenance.

Patients with newly diagnosed advanced stomach cancer should now have Claudin 18.2 tested alongside HER2, PD-L1 and mismatch repair, because roughly a third will be eligible for zolbetuximab, which adds about three months of median survival. The main practical problem is nausea and vomiting during infusions, which needs aggressive prophylaxis. How to sequence or combine it with immunotherapy in PD-L1-positive tumours is unresolved.

TRANSFORM confirmed ZUMA-7's conclusion with a different CD19 CAR-T and a more permissive design that allowed bridging chemotherapy, making the results closer to real-world practice. Liso-cel's low toxicity makes it attractive for older or frailer patients and for outpatient delivery. Together the two trials made CAR-T the standard second-line therapy for early-relapsing aggressive lymphoma.

CARTITUDE-1 showed that a single CAR-T infusion can put late-stage myeloma into deep, multi-year remission, leading to FDA approval of cilta-cel in 2022 for heavily pretreated disease. It set the efficacy bar for BCMA-directed therapy and motivated moving CAR-T earlier (CARTITUDE-4). Late neurological toxicity and secondary malignancies remain the safety questions.

Patients with newly diagnosed advanced stomach or oesophageal adenocarcinoma whose tumour is HER2-negative and PD-L1 positive (CPS 5 or more, or at least 1 in some regions) should receive chemotherapy with nivolumab (or pembrolizumab, from KEYNOTE-859), which adds about three months of median survival and doubles the chance of being alive at three years. The benefit in PD-L1-negative tumours is doubtful, and these patients may be better served by chemotherapy alone or by trials.

School-based vaccination at 12-13 with high uptake nearly abolishes cervical cancer in vaccinated cohorts, even with a vaccine covering only two HPV types. Screening intervals and the future of cervical screening can now be redesigned around vaccination status.

Older patients are more likely to be harmed by standard-dose chemotherapy, and a structured assessment of function, cognition, nutrition and social support lets oncologists adjust treatment safely. Starting lower does not appear to shorten life. Most older patients still do not get such an assessment.

People with Lynch syndrome should be offered daily aspirin, which roughly halves bowel cancer risk with a delayed and durable effect. Whether a lower dose (as tested in CAPP3) is as effective, and whether the finding extends to the general population, are separate questions.

ELEVATE-TN put a more selective BTK inhibitor into first-line CLL and, with the head-to-head ELEVATE-RR trial, showed it is as effective as ibrutinib with fewer cardiac side effects. Continuous acalabrutinib became one of the two main front-line options alongside fixed-duration venetoclax combinations. The trade-off is indefinite therapy and cost versus a time-limited course.

The UCART19 report was the first clinical evidence that a universal, pre-manufactured CAR-T made from a donor can work, avoiding the weeks of autologous manufacturing and the problem of patients whose own T cells are too damaged. It set the template for later allogeneic programmes (including cemacabtagene autoleucel in the ALPHA studies) and for in vivo CAR generation. Short persistence and the need for deep lymphodepletion remain the central weaknesses.

Patients with head and neck squamous cell cancer that has recurred or spread should be treated first with pembrolizumab: alone if their tumour is strongly PD-L1 positive and they can wait for a slower response, or with chemotherapy if the tumour is bulky or PD-L1 low. Cetuximab-based chemotherapy is no longer the default. Long-term follow-up shows a small but real group of patients alive at four to five years, which was almost unheard of before.
