Bevacizumab Allows Preservation of Liver Function and its Regenerative Capacity after Major Hepatectomy

The Safety Profile of Hepatectomy Following Preoperative Systemic Therapy with Lenvatinib Plus Anti-PD-1 Antibodies Versus Hepatectomy Alone in Patients With Hepatocellular Carcinoma

Objective

To determine the safety of hepatectomy after combined lenvatinib and anti-PD-1 preoperative systemic therapy (PST) in patients with marginally resectable hepatocellular carcinoma (HCC).

Background

PST followed by hepatectomy (PSTH) is an emerging treatment for HCC. However, the impact of PST with lenvatinib plus anti-PD-1 antibodies on surgical safety is unknown.

Methods

Medical records from consecutive patients with marginally resectable advanced HCC who underwent hepatectomy after PST with lenvatinib and anti-PD-1 antibodies between January 2018 and August 2021 were retrieved from a prospectively designed database. Propensity score matching (1:2) was performed with a further 2318 HCC patients who underwent upfront hepatectomy (UH) without initial antitumor treatment during the same period.

Results

In total, 49 and 98 matched patients were included in the PSTH and UH groups, respectively. Compared to the UH group, individuals in the PSTH group experienced more intraoperative blood loss, blood transfusions, and longer postoperative hospital stays. Moreover, posthepatectomy liver failure was more common in the PSTH group, who also had worse albumin-bilirubin (ALBI) scores on postoperative days 1-7. A significantly greater amount of drainage was also required in the PSTH group. However, the 30-day morbidity and 90-day mortality were similar among the two groups. Additionally, the duration of surgery, use of hepatic inflow occlusion during surgery, and the levels of postoperative inflammation-based markers were not statistically different between the two groups.

Conclusions

Despite more intraoperative and postoperative adverse events, PSTH had comparable 30-day morbidity and 90-day mortality as UH. Thus, PSTH appears to be a viable treatment option for marginally resectable HCC patients with careful preoperative evaluation.

Bilateral adrenal haematoma complicated by adrenal insufficiency in a patient treated with bevacizumab

Bevacizumab (bev) significantly improves outcomes of patients with metastatic colorectal cancer (mCRC). However, the addition of bev to concurrent chemotherapy significantly increased the risk of haemorrhage. We describe the case of a patient with mCRC who presented with acute diffuse abdominal pain following four cycles of bev-containing systemic chemotherapy. A CT revealed the appearance of bilateral adrenal enlargement suggestive of acute adrenal haematoma. Blood test results showed a dramatic decrease in cortisol level and highly elevated Adrenocorticotropic Hormone (ACTH) level suggesting an adrenal insufficiency. After differential diagnosis, we hypothesised that bev may have contributed to the development of a bilateral adrenal haematoma complicated by adrenal insufficiency. Bev was immediately withdrawn and the patient was subsequently treated with hydrocortisone substitution with favourable outcome. This case highlights for the first time the possibility of adrenal bleeding with bev-containing chemotherapy.
