Assessment, Investigations and the Decision making process
Initial Investigations and Assessment
1. Full history and physical examination as outlined in the Neuro Oncology Data Sheet (NDS). A copy of NDS can be obtained by writing to us.
2. Baseline investigations:
a) Laboratory (we do not carry out any baseline investigations except when indicated as in unknown primary with brain metastases.)
b) Imaging review of all previous imaging
3. Review of histology:
Submit slides with full details to our pathology department Attach outside histopathology report. In cases of NHL, round cell tumors and PNETs or where the diagnoses is doubtful or not correlating with radiological diagnoses, we ask for paraffin blocks or 4-6 unstained slides for immunohistochemistry.
4. Evaluation of physical, functional and psychological status:
All new patients seen in the NeuroOncology Clinics are also evaluated in the simultaneously running BTF clinics, where patients are evaluated for their physical, functional and psychological assessments. Special emphasis is laid on identifying their potential needs during and after treatment and a plan of action charted detailing appropriate steps to meet their and family's needs.
The Decision Making Process
All new cases are evaluated by a consultant and a treatment plan is formalized. Patients requiring multidisciplinary postoperative management, those with a diagnostic or therapeutic problem, interesting cases and patients eligible for trial are discussed in the weekly Joint NeuroOncology Meeting (JNOM). JNOM is held every Thursday at 2 pm at ‘Dr. Sirsat Room’, Dept of Pathology, 8th floor, Annexe Bldg.
Guidelines for Medical Decompressive Therapy
Starting dose of Dexamethasone / Mannitol:
A) Headache (not severe*) and or vomiting (not severe#): |
Dexamethasone 6mg daily (2mg, 8 hourly). |
B) Headache (not severe*) and or vomiting (not severe#) WITH new or worsening focal neurological deficit: |
Dexamethasone 12mg daily (4mg, 8 hourly). |
C)*Severe Headache OR #Severe vomiting OR deteriorating consciousness: |
Dexamethasone 24mg daily (8mg, 8 hourly) with 20% Mannitol, 1g/kg, 6-8 hourly. |
*Severe Headache: perceived as severe or incapacitating by patient
#Severe vomiting: persistent for >12 hours, unable to retain any food
Tapering schedule :
If no improvement is seen within 24 hours, increase dose to the next level/s (B or C) and stop steroids if no improvement even after 48 hours of 24mg dexamethasone with mannitol. If symptoms improve and then stabilize or continue improving, taper dexamethasone every 48 hours: 24,20,16,12,8,6,4,2mg/day and stop. For deterioration while tapering, revert to the previous dose/s every 48 hours, and then attempt tapering. If escalation is required twice (steroid dependence), attempt tapering every 5th day.
Intensity Modulated Radiotherapy (IMRT)
Indications: Mainly for base of skull meningiomas, chordomas.
Rationale: To try to deliver higher doses to chordomas and atypical or malignant meningiomas
Technical policies: To use rigid positioning device only. CT and MR fusion for tumour delineation. CTV and PTV are contoured as for individual sites. Libraries for dose constraints for individual sites devised.
Stereotactic Irradiation (SRS and SRT)
Stereotactic Conformal Radiotherapy (SCRT)
Immobilisation in BrainLAB mask/frame system
Imaging
- Localisation/planning CT scan in the frame (Double contrast, 3/3mm in the tumour bearing are and 5/6mm outside)
- Planning MRI with 1-3 mm cuts. Contrast enhanced 3DFSPGR axial sequence only.
- Fusion of planning CT and MRI on Brain LAB
Target Delineation
- GTV = enhancing mass including areas presumed to contain active tumour Critical structures including eyes, optic nerves/chiasm (and hypothalamus) and brain stem to be outlined
- CTV margin = 0 to 5 mm and edited appropriately
- PTV margin = 2 mm
Planning technique: 6-8 non-coplanar fields, individually shaped with microMLC of the BrainLAB.
Dose Prescription: Dose prescribed at isocentre (plans normalised to 100% at isocentre) with PTV covered by 95% isodose line as per ICRU 50 guidelines
- Pituitary adenoma 45Gy in 25# in 5 weeks
- Craniopharyngioma 54Gy in 30# in 6 weeks
- Meningioma and Acoustic neuroma 54Gy in 30# in 6 weeks
- Optic nerve meningioma 50.4 Gy in 30# in 6 weeks
Trial Consider patients between 6-25 years with low-grade glioma, craniopharyngioma and meningioma for SCRT Trial (conventional vs SCRT).
Stereotactic RadiosurgeryCommon Indications: Solitary brain metastasis and AVM
Immobilisation and Imaging: as in SCRT
Target Delineation
- TGTV = enhanced lesion
- PTV = GTV + 2mm in 3D
Planning technique: 6-9 non-coplanar individually conformed fixed fields
Dose Prescription
- Solitary brain metastasis 15-20 Gy in single fraction, prescribed at 90-95% isodose (plans normalised to 100% at isocentre).
- Recurrent high grade glioma 30-35Gy in 6-7 daily fractions
- AVM- assess the suitability of SRS after discussing in the JNOM. Check size, location and supply of the lesion. Planning MRI and MRA a few days before actual day of the procedure. Dose- 12-25 Gy (individualised).
Performance Scales Follow-Up Policy
KPS (Karnofsky Performance Score)
- 100% = Normal; no complaint; no evidence of disease.
- 90% = Able to carry on normal activity; minor signs of disease.
- 80% = Normal activity with effort, some signs or symptoms of disease.

Astrocytic Tumors (Gliomas) Ependymomas
The diagnosis of a brain tumour comes with a host of problems - fear of the future, readjustments in life, loss of job, change of lifestyle, anxiety about treatment or commitments, practical coping problems, depression, a sense of isolation or weariness caused by the disease and the side effects of the treatment. There may also be concerns regarding treatment, fears of relapse, coping with pain and a host of questions which you will have. To help you cope better, discuss these concerns with trained counsellors at the BTF. They will guide you through options, and search out ways to ease your problems - whether physical, psychological or social - and help in equipping you to face the uncertainties of life.
Children with brain tumour have a different set of coping problems and need sensitive and careful handling. It is essential that all those concerned and affected seek comfort during this physically demanding and confusing period. The BTF counsellor can be very useful at this time.
Financial Assistance: BTF will assess patients who cannot afford necessary investigations or treatment and if appropriate, refer them to the hospital social worker or other support agencies for help.
Craniospinal Radiotherapy
Brain tumour patients have reported varying degrees of psychological and sometimes physical relief from alternative or complimentary systems such as Ayurveda, homeopathy, reiki, accupuncture, meditation and yoga. In our scientific opinion, these complimentary systems of medicine cannot cure a brain tumour but we also realise that a lot of our patients do try these.A word of caution though: Many of these alternative therapists make tall claims of "Sure Cure" treatments in order to extort large sums of money from patients and families desperately looking for hope.
Consult your doctor or the BTF staff, if you decide to undergo any alternative therapies. This will help in ensuring that:
- you are not exploited.
- the therapy does not conflict with our hospital treatment.
- the efficacy of the treatment is evaluated by experts.
Pituitary Tumors, Craniopharyngiomas, Meningiomas, Chordomas
At times, the illness can compel you to remain at home. If you are unable to reach the hospital, you can ask your family member to inform BTF, who will try to arrange home visits of professionals and volunteers from BTF and the Palliative Care Team of Tata Hospital to help you.
If a patient needs terminal care outside the home:
Should the family find that adequate care cannot be arranged for a terminally ill patient at home, a hospice that is equipped with medical facilites can be arranged by BTF. A list of hospices is with the BTF staff and they can help you arrange one. Here are a couple of such hospices in Mumbai.

Primary CNS Lymphomas
The treatment of brain tumour involves a lengthy process, which requires you to be close to the hospital. This can be a problem if you do not live, or have relatives, in Mumbai. Often those affected may face difficulties in movement, especially travelling in buses and trains while commuting to and from the hospital. Talk to the BTF staff and your hospital social workers about your problems. They will advise you about special buses organised by the hospital, and also suggest places you and your family can stay during the course of your treatment - of course, depending on your need and affordability.A list of accommodations, their addresses, name of person to contact, and charges, if any, are with the BTF staff.
