15 Frequently Asked Questions : Proton Therapy in India for Omani Patients

Q1 · What is Proton Therapy?

Proton Therapy is a form of radiation treatment that uses accelerated protons to deliver radiation to a tumour. Unlike conventional photon radiation, protons can be planned so that most of their radiation dose is deposited within a targeted area, with substantially less radiation beyond the planned treatment depth. This characteristic may be useful when treating tumours located close to sensitive structures.

Proton therapy may be considered for selected

• Brain and skull-base tumours
• Head and neck cancers
• Childhood cancers
• Spinal and paraspinal tumours
• Certain sarcomas
• Selected thoracic tumours
• Other cancers where reducing radiation exposure to nearby normal tissues may be clinically valuable

The suitability of proton therapy must be assessed individually.

Q2 · What is the cost of Proton Therapy in Oman compared with India?

Proton Therapy is generally more specialised than conventional radiotherapy, and the final cost depends heavily on treatment planning and the number of treatment sessions.

Indicative Cost Comparison

*Potential savings are indicative planning estimates and are not guaranteed. Final costs depend on tumour type, treatment complexity, number of fractions, planning requirements, imaging, medicines, hospital charges and complications. Patients should obtain a written quotation that clearly states whether consultation, treatment planning, imaging, radiation sessions, specialist fees and follow-up are included.

Q3 · Which Indian cities can Omani patients consider for Proton Therapy and advanced cancer care?

Omani patients should focus primarily on centres with the required proton-treatment infrastructure and an experienced radiation oncology team. For broader oncology evaluation, treatment planning and multidisciplinary care, patients may consider major Indian medical cities including:

Because proton therapy requires specialised infrastructure, patients should confirm availability of the exact treatment before making travel arrangements.

Q4 · Which hospitals in India can Omani patients consider for Proton Therapy and cancer treatment?

The following hospitals are part of the established Indian medical-hospital reference list. Important: Proton therapy is a highly specialised technology and is not available at every hospital. Availability, treatment capacity and suitability must be confirmed for the individual patient.

Q5 · Which cancers may be considered for Proton Therapy?

Proton therapy may be considered for selected cancers where reducing radiation exposure to nearby normal tissues may be important.

Potential applications include

• Brain tumours
• Skull-base tumours
• Head and neck cancers
• Spinal tumours
• Paraspinal tumours
• Selected paediatric cancers
• Certain sarcomas
• Selected thoracic cancers
• Certain recurrent tumours
• Other tumours near critical organs

The decision depends on the exact tumour location and anatomy. The fact that a cancer can technically be treated with proton therapy does not necessarily mean proton therapy provides a meaningful advantage over modern photon radiotherapy.

Q6 · Who may be suitable for Proton Therapy?

Patients may be evaluated for proton therapy when

• The tumour is close to critical organs
• The patient is a child or young person
• A reduction in radiation exposure to healthy tissue is particularly important
• The tumour has a complex location
• Previous radiation makes additional treatment challenging
• The expected benefit from proton treatment justifies its cost and travel

The radiation oncology team may consider

• Cancer type
• Stage
• Tumour size
• Tumour location
• Previous treatment
• Previous radiation dose
• Age
• General health
• Expected treatment benefit

A treatment-plan comparison between proton and photon radiation may be useful in selected cases.

Q7 · What tests are required before Proton Therapy?

The evaluation may include

• Biopsy
• Histopathology
• Immunohistochemistry
• Molecular or biomarker testing where relevant
• CT scan
• MRI
• PET-CT where appropriate
• Previous radiation treatment records
• Blood tests
• Previous surgical reports

A specialised planning CT is generally required for treatment planning. The radiation team may also need previous radiation plans if the patient has already undergone radiotherapy.

Q8 · What medical documents should Omani patients send before travelling?

Patients should send a complete medical record, including

• Biopsy report
• Histopathology report
• Immunohistochemistry
• Molecular/biomarker reports
• CT reports and images
• MRI reports and images
• PET-CT reports and images
• Previous operation reports
• Previous chemotherapy records
• Previous radiotherapy records
• Previous radiation dose and treatment fields
• Blood-test results
• Current medications
• Discharge summaries

For patients previously treated with radiation, the original radiation treatment plan and dose information can be particularly important. The treating team can then determine whether proton therapy is appropriate and whether it offers a meaningful advantage over other radiation techniques.

Q9 · How does Proton Therapy work?

The treatment process generally involves several stages.

Step 1: Medical Assessment

The patient's diagnosis, stage and previous treatment are reviewed.

Step 2: Radiation Oncology Consultation

The specialist determines whether radiation is appropriate.

Step 3: Proton Therapy Assessment

The team evaluates whether proton therapy offers a potential dosimetric or clinical advantage.

Step 4: Simulation

A planning CT and, when necessary, additional imaging are obtained.

Step 5: Treatment Positioning

A reproducible treatment position is established.

Step 6: Treatment Planning

The radiation team develops a proton treatment plan around the tumour and nearby organs.

Step 7: Plan Verification

The plan undergoes appropriate checks before treatment.

Step 8: Proton Treatment

Treatment is delivered according to the prescribed schedule.

Step 9: Monitoring

The patient is monitored for treatment-related effects.

Step 10: Follow-Up

Follow-up imaging and oncology review are arranged according to the cancer type.

Q10 · Are there alternatives to Proton Therapy?

Yes. Depending on the cancer, alternatives may include:

Modern Photon Radiotherapy

Techniques such as IMRT, IGRT and VMAT can provide highly conformal radiation treatment for many cancers.

Stereotactic Radiotherapy

SRS, SRT or SBRT may be appropriate for selected tumours.

Surgery

Surgery may be the primary treatment for selected localised tumours.

Chemotherapy

Chemotherapy may be used before or after local treatment or as the main treatment for certain cancers.

Targeted Therapy

Targeted medicines may be appropriate where specific molecular alterations are present.

Immunotherapy

Selected cancers may respond to immunotherapy.

Brachytherapy

Brachytherapy may be suitable for certain cancers.

The most appropriate alternative depends on the cancer diagnosis, location, stage and treatment objective.

Q11 · What should Omani patients ask before accepting a Proton Therapy quotation?

Patients should ask

• Is proton therapy medically recommended for this cancer?
• What specific benefit is expected compared with photon radiotherapy?
• Has a proton-versus-photon treatment-plan comparison been performed?
• What is the exact cancer stage?
• How many treatment sessions are required?
• Is treatment planning included?
• Is simulation included?
• Are immobilisation devices included?
• Are imaging and image guidance included?
• Are specialist consultation fees included?
• Are medicines included?
• Are laboratory tests included?
• Are hospital admission charges included if required?
• What side effects should be expected?
• What complications could increase the total cost?
• How long must the patient remain in India?
• Can treatment continue without interruption?
• When can the patient safely return to Oman?
• What follow-up is required?
• Can follow-up be coordinated with an oncologist in Oman?

Patients should request a detailed written quotation before making travel arrangements.

Q12 · How long should Omani patients stay in India for Proton Therapy?

The total stay depends on the complexity of the case and number of treatment sessions.

Initial Evaluation

Several days may be required for consultations, review of medical records, imaging and planning.

Treatment Planning

Planning may require additional time after the initial consultation.

Proton Therapy

The treatment course may involve repeated outpatient sessions over several weeks, depending on the prescribed schedule.

Complex Treatment

Patients receiving surgery, chemotherapy or another treatment together with proton therapy may need a longer stay.

Before travelling, patients should ask

• How many days are needed for planning?
• When will treatment begin?
• How many treatment sessions are required?
• Are treatments given every weekday?
• Is hospital admission necessary?
• When can the patient fly home?
• What follow-up must be completed before departure?

Q13 · What are the side effects and recovery after Proton Therapy?

Proton therapy can cause side effects because it is still a form of radiation treatment.

Possible effects include

• Fatigue
• Skin changes
• Localised irritation
• Hair loss within the treated area
• Nausea depending on the treatment site
• Appetite changes
• Mouth or throat symptoms for some head-and-neck treatments
• Bowel or bladder effects for selected treatment areas

The side effects depend on

• Treatment location
• Radiation dose
• Number of sessions
• Tumour size
• Nearby organs
• Other cancer treatments

One potential advantage of proton therapy is the ability to reduce radiation dose to selected normal tissues, but this does not eliminate radiation-related risks. Patients should receive detailed post-treatment instructions and know which symptoms require urgent medical review.

Q14 · How can follow-up be managed after returning to Oman?

Before leaving India, patients should obtain a complete treatment summary containing

• Final diagnosis
• Pathology report
• Proton treatment summary
• Total radiation dose
• Number of fractions
• Treatment dates
• Treatment area
• Relevant imaging
• Concurrent chemotherapy or other treatment
• Medication list
• Follow-up schedule

The patient should also ask when the next

• Clinical review
• Blood test
• CT/MRI/PET-CT
• Oncology consultation

is required. Follow-up can often be coordinated between the Indian cancer team and the patient's treating doctors in Oman.

Q15 · Should an Omani patient travel to India for Proton Therapy?

India may be considered when a patient requires evaluation for proton therapy, particularly when the tumour is close to critical structures or when reducing radiation exposure to healthy tissues is an important consideration. However, proton therapy is not required for every cancer.

Before travelling, Omani patients should compare

• Cancer diagnosis
• Cancer stage
• Tumour location
• Pathology
• Molecular findings where applicable
• Previous treatment
• Previous radiation dose
• Proton versus photon treatment plans
• Expected clinical benefit
• Number of treatment sessions
• Total treatment cost
• Duration of stay
• Travel requirements
• Follow-up arrangements in Oman

Obtaining a specialist opinion based on complete medical records before travelling can help determine whether proton therapy is appropriate.
