Background: There is no agreement regarding a staging system and optimal treatment of Merkel cell carcinoma. Some centres have reported results from larger series of patients, but these do not include Asian or Japanese centres.
Objective: The purpose of this study was to retrospectively review our experience with the surgical treatment of MCC of the face in the Japanese and to study its management and outcome using the staging system described by Clark et al.
Methods: We report our experiences with 16 cases between 1991 and 2004. Patients and tumour characteristics, treatment variables and outcome were analysed.
Results: The follow-up periods ranged from 1 to 180 months. The average was 32.6 months and the median was 17.5 months. The relapse-free survival for all patients was 51% at 2 years. The relapse-free survival was 80% for the patients with Stage I and 33% with Stage II at 2 years.
Conclusion: This staging system was suggested to reflect prognosis although the number of patients in this series was small. Sentinel lymph node biopsy should be considered to determine the accurate nodal staging, and patients with MCC of the head and neck may be treated according to the revised staging system by Clark et al.

Introduction Recently, immune cells within the tumor microenvironment (TME) have become crucial in regulating cancer progression and treatment responses. The dynamic interactions between tumors and immune cells are emerging as a promising strategy to activate the host's immune system against various cancers. The development and progression of hepatocellular carcinoma (HCC) involve complex biological processes, with the role of the TME and tumor phenotypes still not fully understood.

We propose and prioritize important outcome domains that should be considered for future research investigating long-term outcomes (LTO) after new onset refractory status epilepticus (NORSE). The study was led by the international NORSE Institute LTO Working Group. First, literature describing the LTO of NORSE survivors was identified using a PubMed search and summarized to identify knowledge gaps.

Organ transplants are used to treat many end-stage diseases, but a shortage of donors means many patients cannot be treated. Xenogeneic organs have become an important part of filling the donor gap. Many current studies of kidney, heart, and liver xenotransplantation have used gene-edited pig organs on brain-dead recipients.

The insect cell-baculovirus expression vector system (IC-BEVS) has been an asset to produce biologics for over 30 years. With the current trend in biotechnology shifting toward process intensification and integration, developing intensified processes such as continuous production is crucial to hold this platform as a suitable alternative to others. However, the implementation of continuous production has been hindered by the lytic nature of this expression system and the process-detrimental virus passage effect.
