Complications of Intrathecal Chemotherapy in Adults: Single-Institution Experience in 109 Consecutive Patients.

Complications of Intrathecal Chemotherapy in Adults: Single-Institution Experience in 109 Consecutive Patients. J Oncol. 2019;2019:4047617 Authors: Byrnes DM, Vargas F, Dermarkarian C, Kahn R, Kwon D, Hurley J, Schatz JH Abstract Acute lymphoblastic leukemia and other aggressive lymphoid malignancies like Burkitt leukemia/lymphoma have high incidence of central nervous system (CNS) involvement. Various solid tumors, most notably breast cancer, can also metastasize into the CNS as a late stage complication causing devastating effects. Intrathecal (IT) chemotherapy consisting of methotrexate, cytarabine, or the two in combination is frequently used for the prophylaxis and treatment of CNS metastasis. Because of the high toxicity of these chemotherapeutic agents, however, their side effect profiles are potentially catastrophic. The incidence of neurotoxicity secondary to IT chemotherapy is well defined in the pediatric literature but is poorly reported in adults. Here, we investigated the incidence of neurologic and nonneurologic side effects secondary to IT chemotherapy in 109 consecutive adult patients over a two-year time period at hospitals associated with our institution. Of 355 IT chemotherapy treatments received by these patients, 11 (3.10%) resulted in paresthesias or paralysis, which we defined as significant neurologic events in our analysis. We also examined minor events that arose after IT chemotherapy, including back pain, headache, fever, vomit...

There is an urgent need to share expertise and offer emergency guidance for breast radiation therapy (RT) during the COVID-19 (Coronavirus) pandemic. As per the World Health Organisation (WHO) statement, our aim and obligation should be “to stop, contain, control, delay and reduce the impact of this virus at every opportunity”. In our roles as healthcare professionals and/or breast cancer experts this translates to minimising exposure of our patients to COVID-19 without compromising oncological outcome.

Purpose: The availability of novel imaging modalities (NIM) in prostate cancer (PCa) has overtaken the evidence informing their use. The recent EORTC consensus statement on modern imaging recognises the need for large-scale clinical trials of novel imaging [1]. The UK environment is well placed to conduct such trials; the NCRI prostate cancer CSG wished to benchmark current UK imaging availability and practice to inform future national trials.

Purpose: The role of pelvic nodal irradiation in prostate cancer remains controversial. Nevertheless, many high-risk patients are treated with prostate and pelvis radiotherapy in addition to androgen deprivation therapy (ADT) [1]. A recent retrospective study [2] and data from the UK Stampede control arm [3] suggest that radiotherapy may be of benefit to node positive patients. The aim of our study was to document outcomes in patients with node positive prostate cancer treated with pelvic nodal radiotherapy in a UK cancer centre.

Purpose: Relapsed or progressive prostate cancer frequently manifests as consecutive PSA rises long before disease is clinically detectable. Imaging with novel radiotracers targeting prostate-specific membrane antigen (PSMA) has been shown to be more sensitive in identifying the site of disease at lower PSA levels compared with conventional imaging, which may provide increased opportunity for salvage therapy, more aggressive local management of oligometastatic disease or increased confidence in proceeding with systemic therapy [1].

Purpose: As doctors we are required to take consent for radiotherapy; we typically take written consent [1]. We must tell a patient if a treatment might result in a serious adverse outcome, even if the likelihood is very small [2]. As many cancer centres move towards tumour site-specific consent forms for prostate radiotherapy we wanted to ascertain if there was consensus.
