Objective response rate (ORR)

Patients with newly diagnosed metastatic colorectal cancer whose tumour carries a BRAF V600E mutation, which is about 8-12% of cases, should now be offered encorafenib and cetuximab together with FOLFOX from the start rather than after chemotherapy fails; median survival has roughly doubled to about two and a half years. BRAF testing at diagnosis is therefore essential, alongside RAS and mismatch repair testing. The regimen is more toxic than chemotherapy alone.

Patients with high-risk bladder cancer confined to the lining whose disease has not responded to BCG now have a bladder-sparing option that clears the cancer in most cases, delivered through a simple outpatient procedure. It may allow many to avoid or defer cystectomy, a life-changing operation. Whether responses translate into avoided progression and cystectomy over the long term, and how it compares with cystectomy on survival, remain to be shown.

Almost every patient newly diagnosed with advanced bladder or urothelial cancer should now be offered enfortumab vedotin plus pembrolizumab rather than chemotherapy, with median survival extended from about 16 months to over two and a half years. Neuropathy and skin toxicity need monitoring and dose adjustment, and patients with severe diabetes or pre-existing neuropathy need care. Platinum chemotherapy remains an option for those who cannot receive the combination.

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.

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.

Revumenib proved that a transcriptional dependency, rather than a kinase, can be drugged in leukaemia, opening treatment for two genetic subgroups that together cover roughly a third of AML plus most infant ALL. It is now approved and is being combined with venetoclax-azacitidine and intensive chemotherapy in front-line trials. Single-agent remissions are often short without transplant.

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.

Patients with metastatic colorectal cancer carrying a KRAS G12C mutation (about 3-4% of cases) who have exhausted standard chemotherapy now have a targeted option that works far better than trifluridine-tipiracil or regorafenib. The higher sotorasib dose is clearly superior, and the EGFR antibody is essential because KRAS inhibition alone barely works in bowel cancer. Responses are still modest and short-lived compared with EGFR or ALK inhibitors in lung cancer.

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.

Patients with small-cell lung cancer that has relapsed after chemotherapy now have a drug that works far better than topotecan or lurbinectedin, and it is the first T-cell engager approved for a solid tumour. Treatment requires inpatient monitoring for the first doses because of cytokine release syndrome, which most centres now manage on a short-stay basis. It does not yet apply to first-line treatment, where trials are ongoing.

CD20 x CD3 bispecifics gave patients whose lymphoma has failed CAR-T, or who cannot access it, an effective off-the-shelf treatment that can be started within days. Epcoritamab and glofitamab are now standard third-line options and are moving into earlier lines and combinations. They do not yet replace CAR-T, whose remissions appear more durable.

KarMMa-3 was the first randomised evidence that CAR-T beats conventional drugs in myeloma and led to ide-cel's approval after two prior lines. It confirmed that earlier use of CAR-T produces deeper and longer remissions than in the end-stage setting. Because responses are shorter than with cilta-cel and OS was not improved, it also sharpened debate about which BCMA CAR-T to use and when.

Elranatamab confirmed that BCMA bispecifics are a class, not a one-off, and its protocol-built dose reduction after response set a precedent for lowering the immunosuppressive burden of T-cell engagers. Patients now have two approved BCMA bispecifics and one against GPRC5D (talquetamab). Choosing between them, and sequencing them with CAR-T, remains guided by availability and toxicity profile rather than head-to-head data.

Teclistamab showed that an off-the-shelf bispecific can approach CAR-T-like response rates in late myeloma, giving patients who cannot wait for or access cell therapy a real option. It also exposed the price: prolonged T-cell engagement causes profound immunosuppression, so infection prophylaxis and immunoglobulin replacement are now routine. Less frequent dosing after response is being adopted to reduce this burden.

Sacituzumab govitecan is a standard second-line or later treatment for metastatic triple-negative breast cancer, roughly doubling survival compared with the chemotherapies it was tested against. Patients should expect neutropenia and diarrhoea, which are manageable with growth factor support and loperamide. Trials are now testing it earlier, in first-line combinations with pembrolizumab and after surgery for residual disease.

Lifileucel proved that Steven Rosenberg's decades-old TIL concept could be industrialised into a licensed product and gave patients with checkpoint-refractory melanoma, who otherwise have few options, a chance of durable remission. It is the first cell therapy approved for any solid tumour. The treatment requires surgery to harvest tumour, hospitalisation for lymphodepletion and IL-2, and specialised centres, so its reach is limited.

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 clear-cell kidney cancer should receive an immunotherapy-based combination; lenvatinib plus pembrolizumab gives the highest response rate and longest PFS of the available options, at the cost of more side effects requiring dose adjustment. Sunitinib alone is no longer an appropriate standard. Choosing among the combinations depends on risk group, symptoms, comorbidity and the value placed on treatment-free survival, which favours nivolumab plus ipilimumab in intermediate and poor risk.

ZUMA-2 gave patients with BTK-inhibitor-refractory mantle cell lymphoma, who previously had a median survival under a year, a therapy with durable remissions in a substantial fraction. Brexu-cel is now standard after BTK inhibitor failure and CAR-T is being tested earlier in the disease. Neurotoxicity rates are higher than in other lymphoma CAR-T trials.

JULIET, with ZUMA-1, showed that CAR-T could rescue a substantial minority of adults with chemotherapy-refractory lymphoma and that complete responders often stay in remission. The lower toxicity of a 4-1BB construct and the option of bridging therapy made it usable in a broader population. The high drop-out between enrolment and infusion remains a lesson about turnaround time.

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.

ZUMA-1 showed that CAR-T can cure a meaningful fraction of adults whose aggressive lymphoma no longer responds to chemotherapy, a group with a historical median survival of about six months (SCHOLAR-1). Axi-cel became the first CAR-T approved for lymphoma and later the first to beat standard second-line therapy in ZUMA-7. The comparatively high neurotoxicity of CD28-costimulated products was also first characterised here.

A drug that shrinks tumours or delays progression on scans has not necessarily been shown to help patients live longer or better. Patients and clinicians should ask what the endpoint was; regulators should insist on timely confirmatory trials; and trialists should validate surrogates before relying on them.

This study is why PD-1 inhibitors were developed across cancers rather than in melanoma alone: unexpected activity in lung cancer, historically thought immune-resistant, changed drug development priorities industry-wide. It also introduced PD-L1 immunohistochemistry as a candidate biomarker and pneumonitis as a signature toxicity. Within five years PD-1 blockade was approved in more than ten cancers.
