practice of head and neck oncology, including but not limited to Head and Neck
Surgery,

Reconstructive Surgery, Radiation Oncology, Medical
Oncology, Pathology, Radiology, Nuclear Medicine, Dietetics, Speech/ Swallowing
Therapy,

Psychological Counselling, Nursing Supervisors, social

4. Training in allied specialties (Even though the presence of all of the below-mentioned
allied specialists at the training center is ideal, trainees should be scheduled for
rotations at outside affiliated centers if the above is not practicable)

a) Dental oncology

FNB trainees may interact with the dental surgeon regarding pre-radiation prophylaxis, post-radiation conservative dental management, and

prevention/management of osteoradionecrosis. Maxillofacial prosthesis training is important, as dental
and prosthetic rehabilitation is integral for patients to return to their
premorbid state.

b) Speech and swallowing rehabilitation:

Trainees will be encouraged to participate in rehabilitation
following management of laryngeal/hypopharyngeal cancer, speech articulation/dysphagia management post glossectomy, and
dysphagia rehabilitation post organ preservation treatment. The fellow is expected to become proficient in TEP
troubleshooting, compensatory maneuvers/rehabilitation, and other aspects of
voice and dysphagia management.

c) Diagnostic anatomical and functional imaging/nuclear
medicine: A week-long interactive rotation between the trainee and a
radiologist experienced in head and neck imaging is suggested. This
allows for discussion of a wide variety of cases by the trainee to
allow understanding of radiological staging and subsequent surgical planning
wherever indicated. The trainee should be able to understand the
decision-making as regards the choice of investigation modality, and also
understand the indications of therapeutic nuclear medicine.

d) Pathology:

A week-long interactive rotation with an experienced
pathologist is recommended. Training will include essential aspects such as
cytopathology,

processing of diagnostic biopsy, surgical specimen
orientation, margin assessment, and a basic overview of routine as well as
intraoperative pathology.

e) Radiation oncology:

The recommendation is for 2 weeks of rotation each year. After this rotation, the trainee should be able to understand
the interplay

between the two specialties in guiding decision-making,
understand the indications of radiation therapy in head and neck cancers,
and understand

the sequelae and toxicities of radiation therapy and their
management/mitigation.

f) Medical Oncology:

The recommendation will be for 2 weeks of training. After this rotation, the trainee should be able to understand the
rationale of decision-making as regards cytotoxic and biological agents
including immunotherapy, and regimen choice based on treatment setting
and performance status. He/she should also be able to understand and recognize the toxicities of common chemotherapeutic agents and their basic
management.

g) Pain management and palliative care:

This is recommended as ongoing interaction with the
pain/palliative care specialist to understand cancer-associated pain and the
pharmacological/

interventional modalities utilized to manage the same. This
interaction will be aimed at gaining further perspective on end-of-life
issues.

h) Preventive Oncology:

This constitutes an essential recommendation and will
incorporate strategies of tobacco cessation, community and physician
initiatives,

the current role of HPV and the appropriate counseling,
management of leucoplakia and other premalignant lesions, and trismus
rehabilitation, among others. The fellow is expected to have conducted at least one
screening camp & one public education activity.

5. Research experience

a) Candidate should fulfill the minimum following requirements in
2 years to be eligible for examination.

b) One paper publication as lead author in PubMed indexed
journal/One conference presentation per year.

c) Candidate should attend at least two HN conferences
(national/international or equivalent) in tenure.

rest on a mutual decision made together by the trainee, program faculty, and
the institution.

6. Rotations at outside centers:

a) External rotation (outside the institute) is recommended if
the institute doesn’t have necessary allied departments suggested for internal
rotation. (especially for Rotations are preferred for dysphagia, dental rehab, and
reconstruction, pain palliative, and psychology)

b) It needs to be done under an External Mentor.

c) The external mentor will have the following
responsibilities: ensuring a beneficial supplemental training period by providing
perspectives of

management practiced by another institution, signing off on
the operative log book at the end of the rotation, and ensuring that the
trainee gets adequate operating room experience during the rotation.

d) Trainees need to log their observations and participation
during these external postings. The trainee also has to submit a written report on
their experience.

e) Upon the fulfillment of the above prerequisites, a
certificate signifying the satisfactory completion of the external rotation will be
issued. This will be an essential document at the time of completion of the fellowship.

7. Meetings/Conferences:

a) The trainee is encouraged to participate and present
papers (at least 2 in tenure of 2 years) at regional, national and international
meetings, which will inspire confidence, bolster awareness and enhance study patterns.

b) The institution may, at its discretion, choose to
reimburse the registration cost of the meeting attended.

c) Candidate must attend at least one meeting every year.

d) Candidate must present one paper every year in the head neck
or allied meetings

8. Suggested syllabus

a) A selected collection of textbooks including basic
science texts, operative and lab manuals, and compendia will be suggested for reading
