Introduction

 Oral complications are common in patients receiving chemotherapy or undergoing radiation therapy of the head and neck.

 Oral complications during cancer treatment are directly linked to ingestion problems, and may even serve as a source of various infections such as aspiration pneumonia, thereby exacerbating systemic conditions, and sometimes preventing the completion of cancer treatment with negative effects on treatment prognoses. The oral health status of patients with cancer is associated with the incidence rate and the degree of severity of oral complications. Effective oral hygiene management before initiating cancer treatment will contribute to the reduction of oral complications such as mouth sores, oral mucositis, or dental infections, and provide important support to facilitate smooth cancer treatment.

The Team and What We Do

 To prevent or reduce oral complications, we check complication during cancer treatment oral conditions of the patients, identify the patients at risk and start preventive measures before cancer therapy begins.

 Our routine activities for cancer patients are below:

1) Management of oral complications of high-dose chemotherapy and/or stem cell transplant before treatment begins

2) Prevention and treatment of oral complications during chemotherapy and/or radiation therapy

3) Perioperative dental management for the prevention of postoperative pneumonia with oral, pharynx and esophageal surgery

4) Making prostheses for restoration of postoperative facial defects

5) Prevention and treatment of medicationassociated osteonecrosis of the jaw (MRONJ)

6) Cooperation business of a medical department and dentistry for the solution to dental problems of cancer patient.

 Total number of patients: 13,618

 Total number of new patients: 2,590

Education

 Lecture and practice training concerning oral health care were regularly held for nurses and residents.

Future prospects

  • Making at new system that strengthen collaboration with nurse ~ An emphasis on preventive dental intervention, carried out screening of oral cavity problems.
  • Contribute to medicine- and dentistry-related collaboration in cancer care hospitals in the region.
