Do we recognize oral cancer? Primary professional delay in diagnosis of oral squamous cell carcinoma.

OBJECTIVES: The occurrence and causes of primary professional delay in diagnosis of oral squamous cell carcinoma (OSCC) were examined. MATERIALS AND METHODS: Factors related to initial diagnosis or malignancy suspicion were evaluated in patients with primary OSCC. The outcome variable was primary professional delay for missed suspicion of malignancy or wrong diagnosis or delayed referral. The primary predictor variable was active care-seeking. Secondary predictor variables were patients' symptoms and clinical findings. RESULTS: Primary professional delay was found in 9.5% of the 528 patients included. Professional delay was 6.6 times more likely to occur in patients actively seeking care than in those whose tumor was an incidental finding (95% CI 1.58-27.58, p = 0.010). Pain (OR = 2.0, 95% CI 1.07-3.87, p = 0.031), ulceration (OR = 2.3, 95% CI 1.29-4.19, p = 0.005), denture fit problem (OR = 3.1, 95% CI 1.25-7.56, p = 0.014), and unhealed tooth extraction socket (OR = 29.6, 95% CI 8.89-98.71, p < 0.001) were significant predictors for primary professional delay. CONCLUSIONS: OSCC patients seek care actively. Primary professional delay affects the care of every tenth OSCC patient. CLINICAL RELEVANCE: The role of health care professionals is essential for early OSCC diagnosis, especially in urgent care. Clinicians' knowledge of the typical symptoms and findings of OSCC should be improved.

Diagnostic delay in autoimmune oral diseases.

Autoimmune diseases (ADs) affect about 5% of the general population, causing various systemic and/or topical clinical manifestations. The oral mucosa is often affected, sometimes as the only involved site. The misdiagnosis of oral ADs is an underreported issue. This narrative review focuses on diagnostic delay (DD) in oral ADs (oral lichen planus [OLP], oral Pemphigus Vulgaris, mucous membrane pemphigoid, oral lupus erythematosus, orofacial granulomatosis, oral erythema multiforme [EM], and Sjogren syndrome). Extensive literature research was conducted via MEDLINE, Embase and Google Scholar databases for articles reporting the time spent to achieve the correct diagnosis of oral ADs. Only 16 studies reported DD in oral ADs. Oral autoimmune vesiculobullous diseases are usually diagnosed after 8 months from the initial signs/symptoms, the Sjogren Syndrome diagnosis usually requires about 73 months. No data exist about the DD in OLP, oral lupus erythematosus, orofacial granulomatosis, and oral EM. The diagnosis of oral ADs can be difficult due to the non-specificity of their manifestations and the unawareness of dentists, physicians, and dental and medical specialists about these diseases. This can lead to a professional DD and a consequential treatment delay. The delay can be attributed to the physicians or/and the healthcare system (Professional Delay) or the patient (Patient's Delay).

Diagnostic delay of oral squamous cell carcinoma and the fear of diagnosis: A scoping review.

The mortality rate of patients affected with oral squamous cell carcinoma (OSCC) has been stable in recent decades due to several factors, especially diagnostic delay, which is often associated with a late stage diagnosis and poor prognosis. The aims of this paper were to: analyze diagnostic delay in OSCC and to discuss the various psychological factors of patients with OSCC, with particular attention to the patient's fear of receiving news regarding their health; and the professional dynamics related to the decision-making processes in cases of suspected OSCC. A preliminary review of literature focusing on OSCC diagnostic delay was performed. Seven articles were included with the diagnostic delay ranging from 45 days to approximately 6 months. Patients' fears and, to a lesser degree, the concerns of dentists, were found to be still poorly investigated. On the basis of the authors' professional experience, the development of oral lesions of unknown origin may generate different behaviors in the decision-making processes by patients and clinicians, and fear may play a key role in the distinct steps of this process. It is crucial to increase awareness and inform patients about the onset of OSCC, and contemporaneously encourage experimental studies on patients' fear and professional behaviors with respect to communication regarding OSCC.

Factors associated with diagnosis delay in head and neck cancer.

INTRODUCTION AND OBJECTIVES: Tumour stage is an important prognostic factor in head and neck tumours. Many tumours are diagnosed in advanced stages despite almost universal healthcare and their being symptomatic. This paper seeks to determine the diagnostic delay in head and neck tumours in our health department, to analyse factors associated with delay and if it is associated with diagnosis in advanced stages. METHODS: Retrospective study of 137 patients with head and neck cancer diagnosed from 2016-2018. Patient delay, delay in primary health care, delay in secondary health care, diagnostic delay and possible associated factors (smoking, location, stage, …) were evaluated. RESULTS: Many patients (44.5%) were diagnosed in advanced stages. The median patient delay was 30 days. The median referral to otorhinolaryngology was 3.5 days. If the referral was made by another specialist (p = .008), the patients were under previous treatment (P=.000) and the tumours were in initial stages (P=.038) this delay was greater. The median from the first visit to otorhinolaryngology was 15 days, higher in regular referrals (43%) (P=.000). The median diagnostic delay was 12 days, higher in surgical biopsies (P=.000). The median professional delay was 58.5 days and total delay was 118.5 days. CONCLUSIONS: Many head and neck tumours are diagnosed in advanced stages. A relationship was not found between diagnosis in advanced stages and diagnostic delay. However, steps must be taken to reduce these excessive delays.

Factores asociados a la demora diagnóstica en tumores de cabeza y cuello / Factors associated with diagnosis delay in head and neck cancer

Introducción y objetivos: El estadio tumoral al diagnóstico es clave en el pronóstico del cáncer de cabeza y cuello. Pese a un sistema sanitario casi universal y ser tumores generalmente sintomáticos, una gran proporción de tumores son diagnosticados en estadios avanzados. El objetivo es conocer el tiempo que se tarda en diagnosticar los tumores de cabeza y cuello en nuestro departamento de salud, analizar si existen factores asociados a su retraso y si este se asocia al diagnóstico en estadios avanzados. Métodos: Estudio retrospectivo de 137 pacientes con cáncer de cabeza y cuello diagnosticados de 2016-2018. Se evaluó la demora del paciente en la búsqueda de atención médica, en la prestación de la atención y en la obtención del diagnóstico, así como la existencia de factores asociados (tabaquismo, localización, estadio, etc.). Resultados: El 44,5% de los pacientes se diagnosticaron en estadios avanzados. Los pacientes tardaron en consultar una mediana de 30 días desde el inicio de los síntomas. Se tardó en derivar a Otorrinolaringología una mediana de 3,5 días. Se evidenció mayor retraso cuando la derivación la hacía otro especialista (p=0,008), si recibieron tratamiento previo (antibiótico, antiinflamatorios no esteroideos, etc.) (p=0,000) y en tumores en estadios iniciales (p=0,038). En la consulta de Otorrinolaringología fueron valorados 15 días después de la derivación. Este tiempo fue mayor en el 43% de los tumores que fueron remitidos de forma ordinaria (p=0,000). Se obtuvo el diagnóstico en 12 días desde la primera visita a Otorrinolaringología, mayor cuando se tomó la biopsia en quirófano (p=0,000). La mediana de retraso médico fue de 58,5 días y el retraso total 118,5 días. Conclusiones: Muchos tumores de cabeza y cuello siguen diagnosticándose en estadios avanzados. No se ha encontrado relación entre el diagnóstico en estadios avanzados y la demora en el diagnóstico. Aun así, es necesario adoptar medidas para disminuir estas excesivas demoras. (AU)

Delays in oral cavity cancer.

While the prognosis for early-stage oral cavity cancer is relatively good; the majority of patients are still diagnosed with advanced-stage disease on presentation with an associated poorer prognosis. The aims of this review are to summarize our current understanding of delays in oral cavity cancer and their impact on stage at diagnosis and survival. The delays pathway can be subdivided into three components: patient, professional, and treatment delays. Patient delay represents the longest interval in the delays pathway usually lasting between 2 and 5 months and being most influenced by cognitive and psychosocial factors. Professional and treatment delays are shorter in most studies, but highly variable depending on the respective healthcare system. Most studies indicate that advanced stage at diagnosis, primary treatment with radiotherapy, treatment at an academic center, and transitions in care are associated with an increased treatment delay. Based on our current understanding, a delay between definitive diagnosis and treatment of 4-6 weeks seems acceptable from an oncologic perspective. Further studies are needed to better define what a 'safe' waiting time is and to understand the psychological impact of delays for patients.

Diagnosis and referral delays in primary care for oral squamous cell cancer: a systematic review.

BACKGROUND: The incidence of oral cancer is increasing. Guidance for oral cancer from the National Institute for Health and Care Excellence (NICE) is unique in recommending cross-primary care referral from GPs to dentists. AIM: This review investigates knowledge about delays in the diagnosis of symptomatic oral squamous cell carcinoma (OSCC) in primary care. DESIGN AND SETTING: An independent multi-investigator literature search strategy and an analysis of study methodologies using a modified data extraction tool based on Aarhus checklist criteria relevant to primary care. METHOD: The authors conducted a focused systematic review involving document retrieval from five databases up to March 2018. Included were studies looking at OSCC diagnosis from when patients first accessed primary care up to referral, including length of delay and stage of disease at time of definitive diagnosis. RESULTS: From 538 records, 16 articles were eligible for full-text review. In the UK, more than 55% of patients with OSCC were referred by their GP, and 44% by their dentist. Rates of prescribing between dentists and GPs were similar, and both had similar delays in referral, though one study found greater delays attributed to dentists as they had undertaken dental procedures. On average, patients had two to three consultations before referral. Less than 50% of studies described the primary care aspect of referral in detail. There was no information on inter-GP-dentist referrals. CONCLUSION: There is a need for primary care studies on OSCC diagnosis. There was no evidence that GPs performed less well than dentists, which calls into question the NICE cancer option to refer to dentists, particularly in the absence of robust auditable pathways.

The association of treatment delay and prognosis in head and neck squamous cell carcinoma (HNSCC) patients in a Dutch comprehensive cancer center.

OBJECTIVE: The increasing volume of head and neck squamous cell carcinoma (HNSCC) patients can lead to longer intervals between histopathological diagnosis and primary treatment. This could cause psychological distress to the patient, but more importantly could possibly lead to tumor progression and decreased survival. Accordingly, this study investigates these relationships. METHODS: The correlation of professional delay and clinical characteristics of 2493 patients, treated between 1990 and 2011 with oral, oropharyngeal, hypopharyngeal and laryngeal SCC, was investigated. Patients were divided in two groups based on treatment delay, defined as the interval between histopathological diagnosis and initial treatment. Univariate and multivariate proportional hazards models were used to assess disease specific survival (DSS) and disease free survival (DFS). RESULTS: Year of diagnosis, tumor site and therapy were significantly related to treatment delay. Tumor stage was not related to treatment delay. Multivariate regression models revealed that the group with a delay of more than 30 days had a better DSS (HR .838, CI .697-.922, p=.041) and DFS (HR .816, CI .702-.947), p=.007) than the group treated within 30 days. CONCLUSION: In our study, treatment delay up to 90 days is not related to impaired survival. This argument can be used extremely cautiously to comfort patients who have to wait several weeks for treatment. Although, possible tumor progression during treatment delay could have led to increased morbidity subsequent to more extensive treatment. Also, possible negative psychological impact of delay in treatment should not be underestimated.

Delay in the diagnosis and treatment of oral cancer.

STATEMENT OF PROBLEM: Oral and pharyngeal cancer is one of the most mortal cancers; however, its quick diagnosis and referral is a crucial factor in enhancing the survival rate of the patients. PURPOSE: The aim of this study was to inspect the referral conditions and the reasons for the delay in curing the patients referred to the educational hospitals in Tehran. MATERIALS AND METHOD: In this retrospective -descriptive study, two hundred and fifty six files related to the oral and pharyngeal cancer were inspected. The documents were obtained from 5 educational hospitals specialized in the field of cancers. Eventually data related to the time difference between the first time of attending to lesion and diagnosing the cancer as patient's delay and until the curing as professional's delay were recorded. RESULTS: The majority of cancers were squamous cell carcinoma (SCC). The patient's delay was recorded in 110 files among the whole files. The mean of the time between the patients' first notice of the problem and the time visiting a primary care clinician was 270 days (range, 0-2520 days). The mean of the time from when the patient visited a primary- care clinician to the starting time of definitive treatment was 90 days (range, 0-270 days). CONCLUSION: In this study, like other studies, SCC was the most common occurring cancer. Delays related to the patients were more than those related to the professionals. And at last, accuracy in recording the files and training the patients were recognized to be the most imperative factors to continue the treatment successfully.
