Approximately 2-5 % of patients with breast cancer (BC) develop leptomeningeal metastasis (LM). 103 consecutive patients with BC were diagnosed with LM and initially treated with intra-CSF liposomal cytarabine from 2007 to 2011 at a single institution. Correlations were determined with respect to patient characteristics and BC subtype with regard to overall survival (OS). At LM diagnosis, 61 % of patients had a 0-2 performance status (PS), the remaining 39 % were severely neurologically impaired. Regardless of PS, all patients received intra-cerebrospinal fluid (CSF) liposomal cytarabine as first-line treatment. Systemic treatment and radiotherapy were also given in 58 and 17 % of patients respectively as clinically appropriate. Second- (intra-CSF thiotepa) and third-line (intra-CSF methotrexate) treatment was administered in 24 and 6 patients respectively. Median OS was 3.8 months (range 1 day-2.8 years). In multivariate analysis, an initial combined treatment, a second-line treatment with intra-CSF thiotepa, an initial clinical response, and a non-'ER/PR/HER2 negative' BC were significantly associated with a better OS. Median OS in this heterogeneous retrospective case series was similar to that of previously observed BC patients treated with intra-CSF methotrexate suggesting intra-CSF liposomal cytarabine is a reasonable first choice therapy of BC-related LM.

The SARS-CoV-2 pandemic has significantly impacted cancer patient management. National and local recommendations to reduce SARS-CoV-2 transmission have been applied in a comprehensive cancer center located in Northern France. We prospectively measured key indicators for three successive eight-week periods: directly before, during, and right after the containment (from 16 March to 10 May 2020). Overall, the number of newly diagnosed and referred cancer patients in our hospital steadily increased (1027; 1135 and then 1704; +11% during containment and +50% just after). To reduce patient transportation, teleconsultations were implemented. Teleconsulting activity steadily increased during the three periods (5, 2025, and 2351). However, a marked decrease in the number of surgical procedures was observed (448; 330 and 288; −26% during containment and −13% just after). We observed a slight decrease in the number of radiation therapy sessions (7761; 7328 and 7075; −6% during containment and −3% just after) and in day-hospital cycles of IV systemic treatment (2891; 2736 and 2717; −5% during containment and −1% just after). We observed an increase in the number of patients admitted to palliative care and a dramatic reduction in clinical trial enrollment. During this 24-week period, organizational changes were mainly characterized by an increase in newly diagnosed cancer patient referral and the implementation of protective measures, such as teleconsultations. Activities in cancer surgery have decreased while radiotherapy and chemotherapy activities were stable.

Introduction Drug interactions involving everolimus are fairly well known because of its common use, primarily as an immunosuppressant. Several recommendations regarding therapeutic drug monitoring are also available for the use of everolimus-based immunosuppression regimens. However, everolimus use in oncology differs substantially, particularly because of the high doses involved. Therapeutic drug monitoring, although sometimes necessary, is not recommended as a routine in oncology. Thus, it was deemed inapplicable due to the lack of clear recommendations. Case report Here, we present a case where a patient was prescribed everolimus for renal cell carcinoma. The patient benefitted from a pharmaceutical consultation prior to treatment initiation, and a drug interaction with verapamil was suspected. Management and outcome: Therapeutic drug monitoring of everolimus was proposed. Based on the everolimus values reported in the literature, trough plasma concentration in the patient was greatly increased. The patient was then diagnosed with grade 4 oral mucositis, thereby requiring temporary suspension of everolimus treatment. Management of adverse effects was performed through multiple medicated mouthwashes. Discussion Therapeutic drug monitoring for everolimus is important for potential drug interactions or the occurrence of severe adverse events. In such cases, dose adjustments should be managed according to everolimus plasma concentrations. Clear oncological recommendations regarding plasma everolimus thresholds are required for a successful follow-up of the patient’s condition and to ensure adequate response to treatment.

The treatment of leptomeningeal metastasis is based on protocols linking systemic chemotherapies and intrathecal injections of antineoplastic agents. Since the late 1960s, cases of accidental intrathecal injections of vinca-alkaloids, which have almost always proved fatal, have been documented. The most concerned countries, supported by the WHO, have published numerous recommendations aimed at reducing this type of risk. The aim of our work was to improve safety procedures for the intrathecal administration of antineoplastic drugs in an oncology hospital: the Centre Oscar Lambret, Lille, France. To this end, we compiled and analyzed a total of eight international recommendations. Our method was to meet the requirements of the AFSSAPS (French agency for the safety of health products), then to adopt recommended procedures in other countries, where appropriate. We considered the whole drugs circuit from prescription to administration. Improvements basically focused on the computerization of prescription, the dilution in mini-bags of vinca-alkaloids, and the additional labeling of intrathecally administered preparations as well as those with some vinca-alkaloids. This multidisciplinary approach to improve our practices complements the precautions taken by healthcare teams.
