Paclitaxel / nab-paclitaxel

A microtubule poison discovered in the Pacific yew tree, among the most used chemotherapies in breast, lung, and ovarian cancer.

Weekly paclitaxel is a backbone of neoadjuvant TNBC therapy; nab-paclitaxel (albumin-bound) avoids steroid premedication and partners with immunotherapy (IMpassion130) and, in 2026, with relacorilant in ovarian cancer and TTFields in pancreatic cancer.

Medicare
Part B (clinician-administered)

Given by infusion or injection in a clinic or hospital outpatient department, so it is a Part B drug: Medicare pays 80% after the Part B deductible and the patient owes 20% coinsurance, uncapped in Original Medicare unless a Medigap policy applies. HCPCS J9267 for paclitaxel (generic). Nab-paclitaxel (Abraxane) is also Part B; generics launched in 2022.

Commercial insurance
covered on label

Multi-source generic; covered under the medical benefit without prior authorisation in most plans, as part of standard regimens. Some plans apply prior authorisation to nab-paclitaxel because of its higher price.

RUBY: dostarlimab with chemotherapy for advanced or recurrent endometrial cancer

Women with newly diagnosed advanced or recurrent endometrial cancer should receive a PD-1 antibody (dostarlimab or pembrolizumab) with their chemotherapy, and mismatch repair testing is now essential because women with dMMR tumours gain a very large and durable benefit. The gain in mismatch-repair-proficient tumours is real but smaller, and molecular classification (POLE, p53, MMR) is increasingly used to decide who benefits most.

CheckMate 816: three cycles of nivolumab plus chemotherapy before lung cancer surgery

Patients with operable stage II-III lung cancer without EGFR or ALK alterations should have chemo-immunotherapy discussed before surgery rather than only afterwards. Three pre-operative cycles do not compromise the operation and improve cure rates. Whether to continue immunotherapy after surgery, as the perioperative trials do, and whether patients with pCR need any further treatment, remain open questions.

KEYNOTE-522: adding pembrolizumab before and after surgery in early triple-negative breast cancer

For stage II-III triple-negative breast cancer, chemotherapy plus pembrolizumab before surgery and pembrolizumab alone afterwards is now the standard approach worldwide, and the survival gain is real, not just a surrogate. It does not apply to stage I disease or to hormone-receptor-positive or HER2-positive cancers. The price is a year of immunotherapy with a meaningful chance of a permanent endocrine side effect such as hypothyroidism or adrenal insufficiency.
