A single-blinded assessment of the effect of communication on psychological burden among oral cancer and oral potentially malignant disorder patients

Precursor Lesions, Overdiagnosis, and Oral Cancer: A Critical Review

Despite the profession placing great emphasis on oral potentially malignant disorders (OPMDs) as a gateway for early recognition and consequently better outcomes for oral cancer, the death rates for lip and oral cavity cancer have remained stagnant for three decades. Evidence shows that only a small fraction of oral cancers are in fact preceded by OPMDs, and that most OPMDs have an annual transformation rate of less than 1%. As OPMDs encompass a very heterogeneous group of oral conditions, it could be argued that only patients with oral mucosal diseases bearing a substantial risk of malignant transformation warrant close surveillance and treatment, these include proliferative leukoplakia, erythroplakia, non-homogeneous leukoplakia, as well as diseases presenting with severe dysplasia at biopsy. In this narrative review, I discuss the intricate epidemiology of the malignancies that we colloquially refer to as oral cancer, explore the limitations of focusing on OPMDs to reduce the incidence and mortality of oral cavity cancer, and argue that a may-be cancer label represents overdiagnosis for most OPMDs.

Association of salivary cortisol and psychological burden in patients with oral cancer and oral potentially malignant disorders: A prospective study

Introduction

This study aimed to find an association between psychological burden (in terms of depression, anxiety, and stress) and salivary cortisol among oral cancer (OC) and oral potentially malignant disorder (OPMD) patients at various time frames.

Methods

In total, 50 patients with OC and OPMD were studied after their informed consent along with 30 healthy controls. Depression, anxiety, and stress scale-21 (DASS-21) was administered and saliva was collected (non-invasively) at different stages including the time of diagnosis, one and three months after intervention (medical or surgical). To avoid diurnal variation, saliva was collected twice (morning and evening). To assess the linear relationship between depression, anxiety, and stress with salivary cortisol, a partial correlation was calculated.

Results

Comparison of salivary cortisol levels among control, OC, and OPMD groups showed a statistically significant difference in both morning and evening values at different point of time intervals. Higher values of salivary cortisol were observed in OC patients (both morning and evening) in comparison to the OPMD or control group. A positive correlation was discerned between stress and salivary cortisol in both OPMD and OC patients, while no association was found for depression and anxiety domains.

Conclusion

The measurement of salivary cortisol effectively demonstrates raised stress levels in OPMD as well as OC patients. Therefore, it is recommended to institute stress management interventions in the patients as part of the treatment of OPMD and OC.

Transcranial direct current stimulation in the treatment of anxiety and depression in patients with oral cancer during perioperative period

This study retrospectively investigated the efficacy of transcranial direct current stimulation (tDCS) in the treatment of anxiety and depression in patients with oral cancer (OC) during the perioperative period (PPP). This retrospective study reviewed the electronic medical records of patients who underwent OC surgery and experienced anxiety and depression during PPP. The patients were divided into the treatment (n = 36) and control (n = 36) groups. The patients in the treatment group received tDCS, whereas those in the control group did not receive tDCS. The primary outcomes included the Self-rating Anxiety Scale (SAS) and the Self-rating Depression Scale (SDS). Secondary outcomes included adverse events (AEs). We analyzed the outcome data before and after treatment. After treatment, patients in the treatment group achieved greater relief in SAS (P < .01) and SDS (P < .01) scores than those in the control group. Regarding safety, no electronic medical records reported any AEs in this study. The results of this study showed that tDCS may help relieve depression and anxiety in patients with OC during PPP. However, high-quality prospective randomized controlled trials are required to confirm these findings.
