Cyclophosphamide is an alkylating chemotherapy that damages DNA in dividing cells. It is part of CHOP for lymphoma, AC for breast cancer and VAC for childhood sarcomas, clears lymphocytes before CAR-T and prevents graft-versus-host disease after transplant; bladder bleeding, infertility and secondary leukaemia are its harms.
Approved 1959. Backbone of CHOP/R-CHOP, AC/TC (breast), VDC/IE (Ewing), VAC (rhabdomyosarcoma), CVP, hyper-CVAD, EMA-CO; lymphodepletion before CAR-T; post-transplant cyclophosphamide for GVHD prophylaxis; low-dose metronomic use. Toxicities: myelosuppression, haemorrhagic cystitis (mesna), infertility, secondary leukaemia, cardiotoxicity at high dose.
Activated by hepatic CYP2B6 to 4-hydroxycyclophosphamide/phosphoramide mustard, which cross-links DNA; acrolein by-product causes bladder toxicity.
1.Cyclophosphamide slips into a pocket on its target.
Oral anticancer drug with an injectable equivalent used for the same indication, so Medicare covers the oral form under Part B (the oral anticancer drug benefit) as well as under Part D; the pharmacy bills whichever applies. IV cyclophosphamide is Part B (HCPCS J9070).
Multi-source generic; covered under the medical benefit without prior authorisation in most plans, as part of standard regimens.

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.
For fit younger patients treated in the intensive German tradition, BrECADD replaces escalated BEACOPP; how it compares with nivolumab-AVD from S1826 is the open question.
Axicabtagene ciloleucel as an option in relapsed follicular and marginal zone lymphoma. Compared with tisagenlecleucel in ELARA, the response rates are higher and the neurological toxicity substantially greater, which is the trade-off a patient and centre weigh.
This trial supplied the randomised proof that was missing for TIL therapy and showed academic centres can run cell-therapy phase 3 trials without industry. It supports TIL as a standard option after checkpoint inhibitor failure in melanoma and underpinned reimbursement in the Netherlands. The comparator, ipilimumab, is itself only modestly effective in this setting, and overall survival did not differ significantly.
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.
R-CHOP remains the standard first-line regimen for diffuse large B-cell lymphoma. The trial is also the clearest lesson in the disease about adopting a regimen on single-arm data: dose-adjusted EPOCH-R had been used widely for a decade before this comparison existed.
Four cycles rather than six for young patients with limited-stage, low-risk aggressive B-cell lymphoma. The saving is two cycles of anthracycline and vincristine in people who will live for decades afterwards.
Confirmation, by a different route from HD18, that the interim scan can safely direct de-escalation in advanced Hodgkin lymphoma, and that most of the toxicity of escalated BEACOPP can be avoided in the 84 per cent of patients who respond early.
