Annual Report 2021

Department of Head and Neck, Esophageal Medical Oncology

Ken Kato, Yoshitaka Honma, Shun Yamamoto, Kazuki Yokoyama

Introduction

 The Department of Head and Neck, Esophageal Medical Oncology focuses on the development of new drugs and establishment of standard chemotherapy regimens, including multimodality treatment with surgery and/or radiotherapy for advanced head and neck cancers (HNCs), consisting of malignancies arising from the oral cavity, nasopharynx, oropharynx, hypopharynx, larynx, nasal/paranasal cavity, salivary gland, ear canal, thyroid and so on. We also focus on the multimodality treatment of esophageal cancer (EC), mainly chemotherapy and chemoradiotherapy. The main histology of HNC and EC is squamous cell carcinoma. However, there is still a wide variety of histological types, especially in the nasal/paranasal cavity, salivary glands, and gastroesophageal-junctional cancer. Therefore, pathological diagnosis is essential, making a treatment strategy based on pathological findings significant in advanced HNCs and ECs.

The Team and What We Do

 The staff of the Department of Head and Neck, Esophageal Medical Oncology consists of 4 medical oncologists. We hold a daily case conference together at 6 pm after finishing routine clinical work and also hold a monthly research conference and discuss the progress of clinical trials or in-house research. Intergroup meetings with the Departments of Head and Neck Surgery, Esophageal Surgery, Endoscopy, Radiation Oncology, Diagnostic Radiology, and Diagnostic Pathology are held weekly to decide optimal treatment strategies for each individual case and to discuss treatment consensus for the disease. In 2021, we treated 505 hospitalized patients (206 of whom were newly diagnosed), including 292 with esophageal/esophagogastric junction cancer, 58 with hypopharyngeal cancer, 15 with oropharyngeal cancer, 10 with nasopharyngeal cancer, and 29 with tongue cancer. Rare cancers of the head and neck region, such as undifferentiated thyroid cancer and salivary gland cancer, have also been treated through referrals from other hospitals. Of these patients, 65 were entered into clinical trials.

Research activities

 A trans-oral/percutaneous biopsy and blood sampling before and after cetuximab and nivolumab provide an excellent opportunity to study biomarkers. We are collecting these fresh samples from patients with HNSCC to evaluate the correlations between gene expression or immunogenic profiles and patients’ outcomes by using genome sequencing, immune-panel, microarray, or real-time PCR techniques.

 We have also been measuring the gene expressions of possible predictive biomarkers by using FFPE samples obtained from surgical resection or trans-oral/percutaneous biopsy. These studies are being performed in collaboration with the Center for Medical Genomics, National Cancer Center Research Institute (NCCRI), or other institutions.

 We have performed an investigator-initiated trial (FRONTiER study) regarding patients with locally resectable esophageal squamous cell carcinoma, to evaluate the safety and efficacy of neoadjuvant chemotherapy with nivolumab. Along with this multicenter trial, biomarker analysis of immunotherapy using biopsy samples, fecal samples and other methods has been conducted with collaborators at NCCRI or other institutions. The results were presented in the ASCO-GI meeting. In addition, the results of a comparative study of preoperative treatment for resectable esophageal cancer (JCOG1109) conducted by Kato at JCOG were presented at the Oral Session at ASCO-GI 2022.

 The results of the global CheckMate-648 study (a study demonstrating the add-on effect of nivolumab and the superiority of nivolumab + ipilimumab combination therapy in first-line chemotherapy patients for esophageal cancer) were published in the New England Journal of Medicine. Kato participated as a corresponding author.

Clinical trials

 We carried out clinical trials in collaboration with the Departments of Head and Neck Surgery, Esophageal Surgery, Gastrointestinal Endoscopy, Radiation Oncology, Diagnostic Radiology, and Diagnostic Pathology in our hospital. Details of clinical trials are summarized in the Table, including JCOG (Japan Clinical Oncology Group) trials, company-initiated trials, and other collaborative investigator-initiated trials. The list of trials conducted in our department and the number of registrations are shown (Table 1).

Education

 Residents and staff make rounds every day and provide on-the-job education. Each staff member conducts lectures for residents every three months, and also distributes them as ZOOM and video archives to facilities with former residents and related facilities. Residents made 7 presentations in Japan and 4 overseas, and published 4 papers in English.

Future Prospects

 We are conducting investigator-initiated clinical trials to examine the usefulness of nivolumab in preoperative treatment for esophageal cancer, and we have also enrolled a large number of patients in investigator-initiated clinical trials for salivary gland cancer in the field of head and neck cancer. In addition, we are currently discussing with a company about conducting a doctor-initiated clinical trial of a combination therapy of photoimmunotherapy and an immune checkpoint inhibitor. We are also conducting joint research with China on investigator-initiated clinical trials of CDK4/6 inhibitors for esophageal cancer. In addition, we will collaborate with other hospitals using ZOOM.
