Outcomes of elacestrant in patients with ER-positive, HER2-negative, ESR1-mutated metastatic breast cancer who received prior endocrine therapy and cyclin-dependent kinase inhibitor in a real-world setting.

BACKGROUND: Real-world data analyses show durable benefits with elacestrant, with or without prior treatment with cyclin-dependent kinase 4/6 inhibitor (CDK4/6i). This cohort focused on patients with ER-positive/HER2-negative estrogen receptor 1 (ESR1)-mutated metastatic breast cancer (mBC) treated with elacestrant after at least one line of endocrine therapy (ET) combined with CDK4/6i (N = 281). PATIENTS AND METHODS: Claims data from the Komodo Research Dataset linked with Foundation Medicine clinical-genomics data were used. Primary outcome was median time-to-next-treatment (mTTNT). RESULTS: In patients with ER-positive/HER2-negative ESR1-mutated mBC who received one to two prior lines of ET + CDK4/6i (n = 108), mTTNT with elacestrant was 8.2 months [95% confidence interval (CI) 6.0-12.2]. In patients who received one to two prior lines of ET + CDK4/6i for ≥12 months (n = 85), mTTNT was 9.0 months (95% CI 7.7-13.7), including an mTTNT of 12.2 months (95% CI 9.0-not reached) in those who received one prior line of ET (n = 31). In patients with liver and/or lung metastasis (n = 169), mTTNT was 6.9 months (95% CI 5.8-8.3), whereas it was 7.4 months (95% CI 5.6-12.9) in patients with brain metastasis (n = 68). In patients with coexisting ESR1- and phosphoinositide 3-kinase-pathway-mutated tumors (n = 115), mTTNT was 6.1 months (95% CI 5.0-8.1). CONCLUSIONS: Elacestrant showed durable benefits in patients with ER-positive/HER2-negative ESR1-mutated mBC previously exposed to at least one line of ET + CDK4/6i, reinforcing the role of elacestrant as a potential first-choice option for patients with endocrine-sensitive tumors.

Treatment of relapsed and refractory acute leukaemia with high-dose cytosine arabinoside and etoposide.

A total of 65 patients under the age of 55 with acute leukaemia received high-dose cytosine arabinoside (Ara-C) in combination with high-dose etoposide without an anthracycline. Complete remission rates for patients with relapsed or refractory acute myelogenous leukaemia (AML) were 15/25 (60%) and 11/16 (69%), respectively. The complete remission rate for patients with refractory or relapsed acute lymphoblastic leukaemia (ALL) was 10/18 (56%). The treatment-related mortality was 17%. Nine patients whose leukaemia relapsed after matched allogeneic, sibling bone-marrow transplantation (BMT) were also treated in this way; the treatment-related mortality in this group was high (7/9) and the duration of remission in the two patients who responded, too short to justify this intensive treatment in such patients. Similarly, patients who underwent BMT after achieving a complete remission with high-dose Ara-C and etoposide did very poorly, only one patient surviving well and disease-free at 8 months. The important finding in this study was the high complete remission rate rapidly obtained in patients with relapsed or refractory AML without using an anthracycline.

Infused vincristine and adriamycin with high dose methylprednisolone (VAMP) in advanced previously treated multiple myeloma patients.

Forty-five patients with relapsed or refractory multiple myeloma received continuous infusions of vincristine (0.4 mg total dose daily for 4 days) and adriamycin (9 mg m-2 daily for 4 days) with a high dose of methylprednisolone (1 g m-2 i.v. or p.o. daily by 1 h infusion), the VAMP regimen. Sixteen (36%) responded, with a median duration of remission of 11 months and median survival of 20 months. Major toxicities encountered were infective and cardiovascular. Two smaller groups of myeloma patients were treated with high dose methylprednisolone (HDMP) alone, or VAMP plus weekly low dose cyclophosphamide (Cyclo-VAMP). HDMP produced short responses in 25% of patients with less toxicity than VAMP. Cyclo-VAMP was used in a highly selected group of patients who had previously responded to high dose melphalan. It was well tolerated and produced responses in 61% of this group.

Hodgkin's disease in an adult with acute lymphoblastic leukaemia.

A 53 year old woman with common acute lymphoblastic leukaemia (ALL) developed Hodgkin's disease 20 months after the initial diagnosis of ALL. This is by far the oldest case of Hodgkin's disease complicating ALL. The unusual presentation and the aetiology of Hodgkin's disease in ALL are discussed.

Transient hydrocephalus in premature infants: Treatment by lumbar punctures.

Three premature infants with post-haemorrhagic hydrocephalus were treated by removing large volumes of cerebrospinal fluid with repeated lumbar punctures. After this treatment, a computerised tomographic brain scan showed that ventricle size had decreased, and subsequent head growth was normal in all three patients. The results suggest that acquired hydrocephalus in premature infants may be transient and that ventricular shunts may not be necessary in all cases.
