REAL-TIME BIOLOGICAL SIGNALING

Immune Cell (T-Cell)

Cancer Cell Evasion
03
Activated Response
THE FUNDAMENTAL BIOLOGICAL CHALLENGE
Your immune system is part of your body's
natural defense.
“But cancer can sometimes hide from
it.”

Tumors deploy molecular decoys known as immune checkpoints to deactivate
white blood cells. Immunotherapy breaks this camouflage, turning defense
back into active response.

01 / BIOLOGICAL PROGRESSION
How Immunotherapy Changes the Story

From stealth immunosuppression to precision reactivation: follow the cellular milestone
pathway.

01
PHASE 1
Natural Surveillance

White blood cells and
Cytotoxic T-cells continuously scan organs for abnormal
genomic variations and cell mutations.

Constant scanning
02
PHASE 2
Cancer Evades
Detection

Malignant tumors produce PD- L1 and inhibitory ligands,
signaling T-cells to power
down and avoid attack.

Immune checkpoint hijacked
03
PHASE 3
Immunotherapy Helps

Antibody medicines bind
specifically to checkpoint
receptors (PD-1, CTLA-4),
blocking the cancer cell’s
stealth signal.

Molecular unmasking
04
PHASE 4
Immune Response

With brakes released, the host
immune army recognizes tumor
neoantigens and activates
targeted cellular destruction.

Antitumor destruction
03 / CLINICAL QUALIFICATION
Could Immunotherapy Be an Option
for You?

Immunotherapy is never prescribed randomly. Our multidisciplinary tumor board navigates an
interconnected 6-point clinical evaluation matrix to determine if your specific tumor will respond.

STEP 01
Cancer Type & Histology

Cancers with established immunotherapy protocols include lung,
melanoma, bladder, kidney, triple-negative breast, and GI tract
malignancies.

1
Tumor Classification Protocol
Stage III/IV or High-Risk Adjuvant
2
STEP 02
Cancer Staging

Administered in advanced, metastatic diseases, or increasingly as
adjuvant treatment post-resection to eliminate microscopic
circulating cells.

STEP 03
Biomarker Profiling

Biopsy tissue undergoes immunohistochemistry: PD-L1 TPS score,
MSI-H / dMMR status, and Tumor Mutational Burden (TMB-High).

3
Crucial Predictive Testing
First-Line vs Relapsed Lines
4
STEP 04
Treatment Line & Sequencing

Evaluating what previous surgeries, chemotherapies, or radiation
doses have occurred to formulate the safest combination
regimen.

STEP 05
Patient Performance Status

Screening for preexisting severe autoimmune disorders (Lupus,
Crohn’s) along with renal and hepatic tolerance metrics.

5
ECOG 0–2 Health Evaluation
Clinical Transparency Principle

Immunotherapy is not suitable for every cancer patient. Every single protocol is scientifically
matched to unique tumor biology and approved clinical guidelines. Dr. Sunil Navalgund reviews
individual histology before recommending any immune regimen.

04 / ADMINISTRATION EXPERIENCE
The Treatment Journey

Immunotherapy is administered in streamlined, predictable outpatient cycles designed
to minimize disruption to your daily life.

PHASE 01
1. Consultation

Biomarker verification, blood panel
reviews, baseline radiographic imaging,
and multidisciplinary tumor board
recommendation.

PHASE 02
2. Infusion Day

Given as an IV Infusion over 30 to 90
minutes in a comfortable day clinic.
Occasional drugs given via
subcutaneous injection or oral pills.

Every 2 to 6 weeks
PHASE 03
3. Monitoring

Continuous symptom check-ins, routine
hormone/thyroid blood draws, and
scheduled CT or PET scans every 8–12
weeks.

PHASE 04
4. Surveillance

Long-term disease control evaluation.
Many patients remain on active therapy
for up to 2 years if disease remains
stable.

While both are systemic treatments, their biological mechanisms and clinical impact differ
completely.

TARGETED BIOLOGICAL APPROACH
Immunotherapy

Empowers your body’s white blood cells to recognize and destroy
cancer.

Does not attack cells directly. Instead, it reconfigures the body’s
immune system to overcome tumor stealth mechanisms.

Cellular selectivity: Targets immune interactions
Immunological memory: Long-term protection potential
Side effects: Related to immune system activation
PARADIGM: HOST-DRIVEN RESPONSE
DIRECT CYTOTOXIC APPROACH
Chemotherapy
Directly targets and interrupts rapidly multiplying cells
throughout the body.

Chemical agents interfere with cell division processes to kill growing
cells, regardless of whether they are malignant or healthy.

Broad cytotoxic impact: Hits all fast-dividing cells
Immediate shrinkage: Rapid tumor reduction action
Side effects: Hair loss, low blood counts, nausea
PARADIGM: DIRECT CHEMICAL CYTOTOXICITY

Clinical Insight: In many current oncology protocols (such as non-small cell lung cancer), both therapies are administered concurrently for enhanced synergistic response.

06 / PATIENT VIGILANCE
Your Body May Respond in Different Ways

Because immunotherapy stimulates the immune system, healthy organs may sometimes
experience temporary inflammation. Recognizing symptoms early ensures rapid clinical
management.

General Fatigue

Feeling persistently tired or with
diminished energy that doesn’t
fully improve with rest.

Skin Changes

Mild itching, rashes, or dry
patches responding readily to
topical corticosteroid creams.

Cough or Shortness of
Breath
Early sign of pneumonitis (lung
inflammation) requiring
immediate oncology alert.
Diarrhea or Bowel Changes
Frequent loose stools or cramping indicating mild colitis,managed with anti-inflammatories.
Fever & Flu-like
Symptoms

Low-grade fever, chills, or
headache following infusion that
generally settles in 24 hours.

Joint & Muscle Stiffness

Mild arthralgia or muscular
discomfort that is safely managed
with supportive care.

Patient Golden Rule: Always report new or changing symptoms to Dr. Sunil Navalgund’s nursing coordinator immediately rather than waiting for your next routine cycle.

07 / SCIENTIFIC HONESTY & REALISTIC EXPECTATIONS
Can Immunotherapy Cure Cancer?

“Immunotherapy can produce profound, durable, and sometimes long-lasting
remissions in responsive patients. However, it does not work for everyone,
and it is not a universal cure for cancer.”

The Hope of Long-Term Control

For patients whose tumors possess high PD-L1
expression or high mutation loads,
immunotherapy has achieved sustained disease
control lasting for years beyond historic
averages.

Tumor Heterogeneity & Resistance

Some cancers develop molecular resistance or
lack neoantigen targets altogether. Precision
genomics ensure we avoid unnecessary
toxicities when immunotherapy is unlikely to
benefit.

Hi- We visited Sparsh Hospital for my mother's cancer treatment, and our experience was very positive. Dr. Sunil, who treated my mother, was exceptionally professional, knowledgeable, and compassionate. He took the time to explain the diagnosis and treatment plan in detail, ensuring that we understood every step of the process. What stood out the most was his calm and reassuring approach. Cancer treatment can be overwhelming for both patients and their families, but Dr. Sunil's patience, confidence, and positive attitude helped ease our fears and prevented unnecessary panic. He was always approachable and willing to answer our questions, which gave us great confidence throughout the treatment journey. We are truly grateful for the care, support, and guidance provided by Dr. Sunil and the team at Sparsh Hospital. Thank you for making a challenging time more manageable for our family.

Review for Dr. Sunil Navalgund. Oncology surgen. Rating: ★★★★☆ I am a 75-year-old patient who recently underwent surgery performed by Dr. Sunil Navalgund for Stage 3 colon cancer. I am writing this to express my sincere gratitude for his skill and professionalism during a very difficult time in my life. The surgery was successful, and I am now well on my road to recovery. Dr. Sunil Navalgund is clearly a very talented surgeon who knows his craft. He took the time to explain the procedure to me and my family, which helped ease some of our anxieties. The clinical outcome has been excellent, and for that, I am truly thankful to Dr Sunil Navalgund. In terms of the actual medical care and the success of the operation itself, I couldn't have asked for a better result. If you are facing a similar diagnosis, I would certainly recommend Dr. Sunil Navalgund.He is a man of great competence, and I am glad he was the one looking after me and he is epitome of simplicity.
