Screening and Management of Oral Cancer at Secondary Level Health Care Facilities

Objectives

This guidance supports India’s operational management component for population-based screening of common non-communicable diseases, with a particular focus on preventing, detecting, diagnosing, referring and managing oral cancer and oral potentially malignant disorders at secondary-level facilities.[1][2]It is intended principally for dental surgeons and other health workers, while linking their work to frontline, primary, secondary and tertiary services.[1][2][3]

• Strengthen early recognition of oral cancer and oral potentially malignant disorders through risk assessment, oral visual examination, mouth self-examination, lesion categorisation, biopsy, histopathology, referral, treatment planning and follow-up.[4][5][3][6]
• Identify people at increased risk from smoking or smokeless tobacco, arecanut, alcohol use, unhealthy diet, chronic physical irritation, human papillomavirus infection, candidiasis and immunosuppression.[7][8]
• Promote tobacco cessation, alcohol de-addiction support where required, oral hygiene, dental prophylaxis and removal of chronic mucosal trauma from sharp teeth, dentures, restorations, implants or malaligned teeth.[9][8]
• Teach individuals and families to undertake mouth self-examination and recognise bleeding spots, ulcers, red or white patches, growths and swelling.[3][10]
• Recognise higher-risk lesions and warning signs, including persistent ulcers, erythroplakia, non-homogeneous or large leukoplakia, lesions of the tongue or floor of mouth, idiopathic leukoplakia and lesions associated with combined tobacco and alcohol exposure.[7][11][6]
• Use biopsy and histopathology to distinguish non-dysplastic lesions, dysplasia, carcinoma in situ and malignancy, with histopathology treated as the diagnostic gold standard.[11][12]
• Stage malignant oral tumours and cervical lymph nodes using the tumour, regional nodes and distant metastases classification to inform prognosis and treatment decisions.[13][14]

The guidance covers a broad spectrum of potentially malignant disorders, including leukoplakia, erythroplakia, proliferative verrucous leukoplakia, oral lichen planus and oral submucous fibrosis.[15][16]It gives particular emphasis to early intervention because an Indian house-to-house survey found that 80% of oral cancers were preceded by oral potentially malignant disorders.[15]

Its clinical objectives include enabling secondary-level dentists to diagnose oral potentially malignant disorders and oral cancer, provide personalised cessation counselling, identify lesions requiring urgent management and maintain recall and referral arrangements.[2][7]The guidance also seeks to reduce functional loss and disease progression through screening of apparently healthy people for oral-cancer risk factors and lesions, prompt treatment and continued surveillance.[2]

For confirmed or suspected malignancy, the intended direction of care is timely specialist assessment and tertiary cancer-centre management, particularly for frank oral squamous cell carcinoma, lymph-node involvement, moderate or severe dysplasia, carcinoma in situ and other cases beyond secondary-level capacity.[3][17][6]

Implementation

The delivery model is tiered: frontline workers promote health, identify risks and visible lesions, provide specific protection and refer patients; dentists and medical officers at secondary level conduct detailed assessment, manage selected potentially malignant disorders, arrange diagnosis and maintain follow-up; tertiary services manage cases requiring specialist investigation or treatment.[2][3]Implementation is supported by management algorithms, clinical proformas, quick-reference cards, examination records, histopathology request forms and referral protocols.[1][6][18][19]

• Develop cadre-specific training and refresher materials for Accredited Social Health Activists, Auxiliary Nurse Midwives, medical officers, specialists and other relevant personnel, using national trainers and state-level master trainers.[1][20]
• Coordinate national training development through the Ministry of Health and Family Welfare’s Non-Communicable Disease Technical Advisory Group, with the National Health Systems Resource Centre serving as secretariat.[1][21][20]
• Engage State Nodal Officers from the National Oral Health Programme and National Tobacco Control Programme, alongside Auxiliary Nurse Midwives, male health workers, Accredited Social Health Activists and non-communicable disease nurses, to channel training and cessation information.[9]
• Conduct systematic extraoral and intraoral examinations with infection control, history-taking, consent, illumination, mirrors, probes, retractors, tongue depressors, gloves, swabs and visual reference materials.[3][22]
• Examine oral tissues sequentially, document abnormal mucosal colour, texture, growths, ulceration, induration and fixity, and assess cervical lymph nodes for characteristics relevant to clinical staging.[13][14]
• Provide personalised tobacco cessation support using tobacco history, the 5 A’s and the 5 R protocol, brief quit advice, withdrawal management, pharmacotherapy where appropriate and follow-up visits.[8]
• Observe selected lesions after removal of contributory factors and cessation counselling, arrange rebiopsy where suspicious changes develop, and refer urgently when clinical findings indicate malignancy or exceed available expertise and facilities.[3][11][17]

Biopsy delivery requires patient assessment, medical clearance and baseline investigations for medically compromised patients where indicated, informed consent in the patient’s language, sterile equipment and careful selection of the most representative lesion area.[23]Incisional biopsy is preferred for oral potentially malignant disorders, with multiple biopsies where suspicious lesions occur at different sites.[23][24]Specimens should be handled gently, separately labelled, placed in 10% neutral buffered formalin and submitted with relevant clinical information.[24]

Histopathological results should be documented, explained to patients and used to determine conservative management, excision, referral and follow-up.[12]Non-dysplastic lesions are generally managed conservatively with reinforced tobacco and alcohol cessation and regular, usually six-monthly lifelong follow-up.[12]Mild dysplasia may be followed at secondary level, whereas moderate or severe dysplasia and carcinoma in situ require tertiary-level surgical management; surgical excision should use at least a 5 mm margin for moderate or severe dysplasia and carcinoma in situ.[17][25]

Operational accountability relies primarily on complete clinical records, referral identification numbers, case sheets, TNM fields, online records and proposed oral cancer and oral potentially malignant disorders registries.[16][3][18][19]The guidance does not specify a formal programme-level monitoring framework, performance indicators, reporting schedule, budget, financing source or resource-mobilisation plan.[1][26][27][21]

Monitoring & Evaluation

Monitoring is principally embedded in clinical screening, documentation, referral and long-term follow-up rather than in a defined programme-wide performance framework. The guidance requires records for screened individuals, lesion assessment, tobacco counselling, treatment, biopsy, histopathology and referral tracking, while proposing online cancer records and national registries for oral cancer and oral potentially malignant disorders.[3][16]

• Record screening details, presenting symptoms, medical history, oral habits, tobacco and alcohol exposure, lesion characteristics, clinical diagnosis, biopsy decisions and referral identification numbers using structured patient proformas and case sheets.[6][18][3]
• Document tumour site and size, cervical lymph-node findings, and tumour, node and metastasis classification to support clinical staging, treatment planning and prognosis.[13][14][18]
• Maintain histopathology documentation, including specimen and collection details, report numbers and dates, microscopic findings, diagnosis, reporting personnel, signatures and whether reports or slides were provided to the patient.[18][19]
• Communicate oral examination findings and document the need for biopsy, treatment, follow-up or referral.[10]
• Maintain recall and referral arrangements for people at risk of oral cancer, ensuring that patients are not lost during secondary-level follow-up.[7][16]
• Review non-dysplastic and mild dysplastic lesions every six months, manage moderate or severe dysplasia and carcinoma in situ at tertiary level, and continue secondary-level follow-up every three months for these higher-risk conditions.[25]
• Undertake lifelong surveillance at intervals of three to six months for high-risk lesions, and rebiopsy mild atypical changes or mild dysplasia if suspicious clinical changes emerge.[25][17]
• Recall patients after seven days for removal of non-resorbable sutures, document and explain histopathological results, and provide regular, usually six-monthly lifelong follow-up for non-dysplastic lesions.[12]
• Train dentists to maintain online records and cancer registries, and establish or develop National Oral Cancer and National Oral Potentially Malignant Disorders Registries.[16][3]

The guidance includes limited outcome-related figures: awareness among people trained in mouth self-examination could reach up to 80%, while treatment compliance may be below 35%.[10]It does not specify a formal indicator set, targets, reporting timetable, evaluation methodology, surveillance protocol, data review process or accountability framework beyond clinical records, registries, referral tracking and follow-up arrangements.[2][3][19]

Costing & Financing

Costing and financing are largely unspecified. The guidance identifies clinical inputs needed for screening, mouth self-examination, biopsy, specimen handling, histopathology, training and referral, but provides no programme budget, unit costs, resource allocation, financing source, resource-mobilisation plan, funding gap or economic model.[10][23][24][21][20]

• Provide basic mouth self-examination materials, namely a face mirror and reasonably bright light.[10]
• Equip clinical examinations with illumination, mouth mirrors, probes, retractors, tongue depressors, gloves, cotton-tipped swabs, examination forms and visual reference cards.[3]
• Supply biopsy and specimen-handling materials, including sterile instruments, labelled containers, 10% neutral buffered formalin and histopathology request forms.[23][24]
• Develop training and refresher materials and national and state training capacity for Accredited Social Health Activists, Auxiliary Nurse Midwives, medical officers, specialists and other relevant providers, without a stated budget.[1][20]
• Recognise tobacco-cessation counselling as highly cost effective, although no monetary estimate, comparator, time horizon or economic assumptions are provided.[8]

No machine-readable budget, expenditure, allocation, funding commitment or quantified financing gap is provided.[1][12][6]
