Covid-19 pandemic: A new contributing factor to diagnostic and treatment delay in oral cancer patients

Delay in diagnosis of oral cancer: a systematic review

Background

Oral cancer represents a worldwide public health problem, being among the most prevalent, associated with high morbidity and mortality rates. This systematic review aimed to review the causes of the delayed diagnosis of oral cancer mainly in the elderly, in developed and developing countries.

Material and Methods

Search strategy was developed for MEDLINE databases (via PubMed), EMBASE, Web of Science, SCOPUS, and LILACS and for grey literature (Google Scholar, ProQuest and OpenGrey), without language or period restrictions. The risk of bias was assessed using instruments from the Joanna Briggs Institute and the quality of evidence according to the GRADE system.

Results

The search resulted in 14,473 records, of which only 13 met the eligibility criteria. The total sample was 1,705 participants, with a predominance of males. All studies included reported causes of delayed diagnosis of oral cancer related to the patient and five also reported causes related to health professionals. The scarce knowledge of the population was pointed out as the main cause of delayed diagnosis of this cancer. Regarding the risk of bias, ten studies were classified as low risk and three, as moderate risk. The quality of the evidence was very low for the outcome related to delayed diagnosis of oral cancer.

Conclusions

Wide dissemination of information on oral cancer is needed, especially for the elderly, such as its initial signs and symptoms, in developed and developing countries. Further studies should be conducted to better understand the causes of delayed diagnosis of oral cancer in countries with different socioeconomic statuses.

Impact of COVID-19 pandemic on oral and maxillofacial surgery in Japan: A report from a questionnaire survey during the different phases of the pandemic

COVID-19 pandemic has provided a new challenge to healthcare systems and medical care providers. In the current study, we describe the challenges faced and actions taken to provide optimum healthcare in Japan during the COVID-19 pandemic based on the results of a questionnaire survey that was conducted by oral and maxillofacial surgeons. A total of 24 Japanese institutions participated in the study. The first survey was conducted between June 22, 2020 and June 26, 2020, and the second survey was conducted between October 23, 2020 and November 8, 2020. The questionnaire focused on the practical situation in the respondent's hospital, personal protective equipment (PPE) availability, and what alterations had occurred compared to the situation before the COVID-19 pandemic. The commonest reported duration of restrictions to the outpatient clinic was 1–2 months. All of the institutions had lifted their restrictions on outpatient services by September 2020. Surgical procedures in the operating room were restricted in 74% of hospitals in the first wave of the pandemic; however, 88% lifted their restrictions and restarted their regular surgical services by November 2020. Although, non-urgent or elective procedures were delayed, surgeries for malignant tumors, maxillofacial infections, and trauma were performed at almost all hospitals during the pandemic. Health care institutions will require a new approach to maintain patient volume and recover from the pandemic. Going forward, it is also necessary to minimize the risk of exposure and transmission to health care personnel as well as patients.
