Oral changes in interleukin-2 treated patients: a preliminary report
1Department of Oral Diagnosis, Hebrew University-Hadassah School of Dental Medicine, Jerusalem, Israel.
Summary
High-dose interleukin-2 (IL-2) immunotherapy caused oral side effects in cancer patients. All patients experienced mucositis and reduced salivary flow, with increased salivary sodium and protein.
Area of Science:
- Oncology
- Immunology
- Oral Medicine
Background:
- High-dose interleukin-2 (IL-2) immunotherapy is used for metastatic cancer.
- This treatment is associated with significant multiorgan side effects.
- The impact of IL-2 on oral tissues is not well-documented.
Purpose of the Study:
- To investigate the effects of recombinant IL-2 (rIL-2) on oral tissues in cancer patients.
- To document oral pathology and subjective complaints during IL-2 therapy.
- To assess changes in salivary parameters alongside routine blood and urine values.
Main Methods:
- Five cancer patients receiving rIL-2 immunotherapy were monitored.
- Oral examinations were performed to note pathology and patient complaints.
- Whole saliva was collected daily for parameter analysis.
- Routine blood and urine tests were conducted daily.
Main Results:
- All patients developed oral mucositis.
- A significant diminution of salivary flow was observed in all patients.
- Elevated levels of salivary sodium and protein were recorded concurrently.
Conclusions:
- High-dose IL-2 immunotherapy adversely affects oral tissues.
- Mucositis and reduced salivary flow are common side effects.
- Alterations in salivary composition, including increased sodium and protein, accompany IL-2 treatment.
