ABSTRACT
Oral colonization and infection by Candida species are common in cancer patients receiving chemoradiotherapy, which has significantly increased in recent years. This study aimed to evaluate the frequency, distribution, and antifungal susceptibility profiles of Candida species isolates in patients with hematological malignancy and solid tumors. This study was conducted on a total of 45 cancer patients undergoing treatment with concurrent chemoradiotherapy within 2019-2020. The identification of Candida species was accomplished based on conventional examination and molecular assays. The minimum inhibitory concentrations were determined based on the guidelines of Clinical and Laboratory Standards Institute. The highest prevalence rates of oral candidiasis were observed in patients with chronic lymphoid leukemia (24.4%) and lymphoma (20%). The majority of the patients had oral candidiasis caused by non-albicans Candida species (64.4%). The results of the multiplex PCR for the identification of Candida glabrata, Candida nivariensis, Candida bracarensis, and species-specific Candida parapsilosis complex showed that all isolate amplification products at 397 bp and 171 bp were related to C. glabrata and C. parapsilosis, respectively. There was a significant difference in the Candida species distribution between the hematological malignancies and solid tumors patients. The results of MIC showed that clotrimazole, voriconazole, and caspofungin were the most effective antifungal drugs against oral non-Candida albicans isolates. An understanding of the epidemiology of oral candidiasis among hematological malignancies and solid tumors patients is currently imperative to guide optimal empirical treatment strategies for affected patients.
