Adjuvant Systemic Immunotherapies for Resected Stage III Melanoma: A Single-Centre Retrospective Clinical Practice Review
Melanoma poses significant challenges due to its resistance to conventional therapies and increasing incidence rates. Stage III melanoma, characterised by regional lymph node involvement, has a high risk of recurrence despite surgical resection. Adjuvant immunotherapy, particularly using the PD-1 inhibitors pembrolizumab and nivolumab, has shown promising results in improving recurrence-free survival (RFS) and overall survival (OS) in Stage III melanoma patients. This retrospective analysis examined the effects of adjuvant pembrolizumab or nivolumab on patients with Stage III melanoma treated in a tertiary oncology centre. Of the 110 patients, 95 received pembrolizumab and 15 received nivolumab. The pembrolizumab completion rate was 62.1%, with 31.2% discontinuing due to disease progression or adverse effects. The nivolumab completion rate was lower at 40%, with 60% discontinuing due to toxicity or disease progression. Grade 3 or higher toxicities were observed in 17% of pembrolizumab and 53.3% of nivolumab patients. Disease progression occurred in 27.4% of pembrolizumab and 26.7% of nivolumab patients. Pembrolizumab showed a 12-month RFS of 78.9% and 24-month RFS of 77.6%, with an OS of 97.9% at 12 months. Nivolumab exhibited a 12-month RFS of 86.7% and 24-month RFS of 80%. RFS rates varied by disease stage and mutation status. Adjuvant pembrolizumab and nivolumab both demonstrate efficacy in improving RFS and OS in Stage III melanoma patients. Pembrolizumab has higher completion rates and fewer toxicities compared to nivolumab. Further studies are warranted to explore long-term outcomes and optimise treatment strategies.
Choledochoduodenal fistula: a rare complication of acute peptic ulcer bleeding
A 75-year-old man presented with a 3-week history of melaena and right upper quadrant pain. This was on a background of significant alcohol intake and a complex medical history. He was haemodynamically unstable with investigations indicating a new iron-deficiency anaemia. After resuscitation, urgent intervention was required under general anaesthesia. This involved a triple phase abdominal CT, followed by emergency oesophagogastroduodenoscopy. This revealed deep ulceration with extension to the pancreatic head and common bile duct. There was also evidence of pneumobilia on CT, secondary to a choledochoduodenal fistula. Treatment encompassed an invasive and medical approach. Following treatment, the patient was stable, with follow-up endoscopy exhibiting good duodenal mucosal healing.
Interpreting the Constitution: Supreme Court Constitution Benches since Independence
Constitution benches have been vital for Supreme Court jurisprudence. But, the number of these benches has fallen since the 1960s. This article examines all constitution benches from independence until the end of 2009. Using this analysis, which paints a far more textured picture of these benches than has previously been available, it makes recommendations to help strengthen the Supreme Court's constitution benches.
