Adjuvant therapy of biliary tract cancers.

Biliary tract cancers (BTCs) are rare and heterogeneous malignant tumours including cholangiocarcinoma and gallbladder cancer. They are very aggressive, often refractory to chemotherapy and associated with an overall poor prognosis. Surgical resection remains the only potentially curative treatment option but less than 35% present with resectable disease. Adjuvant treatments have been widely used but until recently, supportive data were limited to non-randomised, non-controlled retrospective studies. Recent evidence from the BILCAP trial has established adjuvant capecitabine as the standard of care. But there are still unanswered questions as to the role of adjuvant therapy. Further prospective data and translational research with reproducible evidence of clinical benefit are needed. In this review of adjuvant therapy in resectable BTCs, we will summarise the latest evidence setting current treatment standards and highlight future prospects.

Small vessel vasculitis and dry gangrene secondary to combined CTLA-4 and PD-1 blockade in malignant mesothelioma.

BACKGROUND: Malignant pleural mesothelioma (MPM) is a rare and aggressive tumour with an overall poor prognosis. In October 2020, first line treatment with the PD-1 antagonist nivolumab and the CTLA-4 antagonist ipilimumab for unresectable disease was FDA approved-the first approved treatment regime since 2004. Interim analyses from the phase 3 CHECKMATE-743 study shows improvements in overall survival. Skin-related toxicities are the most commonly reported any-grade treatment-related adverse event from combined nivolumab and ipilimumab therapy. CASE PRESENTATION: Here we report a case of a 35-year-old white male who developed digital ischaemia secondary to small vessel vasculitis after receiving PD-1 and CTLA-4 blockade therapy for MPM. His progressive ischaemia became gangrenous, and he required multi-speciality input and treatment with prednisolone, prostacyclin, mycophenolate mofetil and hydroxychloroquine. CONCLUSIONS: Our case highlights the importance of early detection, intervention, and a multispecialty approach to managing such complications in order to minimise the associated morbidity and mortality.

Caring for our cancer patients in the wake of COVID-19.

In response to our current global pandemic, unprecedented healthcare changes may have significant consequences for cancer patients in the United Kingdom. We explore why cancer patients may be more susceptible to severe infection and complications, highlighting various interventions that may help to ensure continuity of care in this unique cohort.

Intravenous thrombolysis in a patient taking warfarin with an international normalised ratio of 1.9.

Intravenous thrombolysis is the mainstay medical treatment for acute ischaemic strokes, but has strict eligibility criteria. Symptomatic intracranial haemorrhage (sICH) is the most adverse complication. A woman aged 76 years presented with signs of an acute stroke and despite not meeting the eligibility criteria, given her background use of warfarin, she received intravenous thrombolysis with an excellent outcome. This is the first fully documented case report of the contraindicated use of intravenous thrombolysis in a patient presenting with an acute ischaemic stroke on a background of concurrent use of warfarin with an international normalised ratio (INR) as high as 1.9. It has been perceived that the risk of thrombolysis with a raised INR outweighs the potential benefits. However, documenting its use outside of the current eligibility criteria is key to future developments.
