ONCOLOGY & CANCER CARE Procedure

Immune Checkpoint Inhibitor Therapy

Immunotherapy utilizes monoclonal antibodies (Keytruda, Opdivo, Tecentriq) to block PD-1/PD-L1 and CTLA-4 immune checkpoints, unleashing the patient's own T-lymphocytes to recognize and destroy cancer cells.

Clinical Overview & Disease Information

Immunotherapy utilizes monoclonal antibodies (Keytruda, Opdivo, Tecentriq) to block PD-1/PD-L1 and CTLA-4 immune checkpoints, unleashing the patient's own T-lymphocytes to recognize and destroy cancer cells.

Signs & Symptoms

Early Symptoms
  • Mild fatigue following IV infusion
  • Transient low-grade fever and chills
Common Symptoms
  • Immune-related skin rash or itching (pruritus)
  • Mild thyroid dysfunction (hypo/hyperthyroidism)
  • Diarrhea or colitis symptoms
  • Joint pain (arthralgia)
Emergency Symptoms
  • Severe immune-mediated pneumonitis (cough & acute dyspnea)
  • Severe immune colitis (> 6 watery stools/day)
  • Acute adrenal crisis

Causes & Risk Factors

Primary Causes & Etiology

  • High Tumor Mutational Burden (TMB-High)
  • Microsatellite Instability-High (MSI-H)
  • Positive PD-L1 Tumor Proportion Score (TPS > 50%)

Who is at Higher Risk?

  • Advanced Non-Small Cell Lung Cancer (NSCLC)
  • Metastatic Melanoma & Renal Cell Carcinoma
  • Triple-Negative Breast Cancer

Diagnostic Evaluation & Testing

Diagnostic Test Clinical Purpose / What It Shows
PD-L1 Immunohistochemistry (IHC 22C3 / SP263) Quantifies tumor cell PD-L1 expression score to predict immunotherapy response
Microsatellite Instability (MSI) & TMB Test Identifies DNA mismatch repair deficiency (dMMR) for tissue-agnostic approval

Comprehensive Treatment Options

PD-1 / PD-L1 Checkpoint Inhibitor Monotherapy Infusion

Intravenous infusion of Pembrolizumab (Keytruda) or Nivolumab (Opdivo) every 3 to 6 weeks.

Key Advantages:
Durable long-term complete responses in responsive patients
Better safety profile than cytotoxic chemo
No hair loss or severe bone marrow suppression

Dual Immunotherapy (Nivolumab + Ipilimumab) or Chemo-Immunotherapy

Synergistic combination of CTLA-4 plus PD-1 inhibitors for advanced melanoma, renal cell, and lung cancers.

Recommended For:
High-risk metastatic cancers
PD-L1 negative tumors requiring chemo priming

Advanced Medical Technologies Available in Partner Hospitals

Keytruda (Pembrolizumab) Opdivo (Nivolumab) Tecentriq (Atezolizumab) Yervoy (Ipilimumab)

Possible Complications If Untreated

Immune-Related Adverse Events (irAEs)
Immune Pneumonitis
Immune Colitis & Hepatitis
Endocrinopathies

Recovery Timeline, Diet & Lifestyle Care

Recovery Timeline

Procedure / Stage Expected Recovery Duration
IV Infusion Session 30 to 60 minutes
Observation & Monitoring 2 hours
Infusion Cycle Interval Every 3 to 6 weeks
Response Assessment PET-CT Every 9 to 12 weeks

Recommended Post-Treatment Diet

  • Balanced gut microbiome diet rich in fiber and fermented foods
  • Hydration 2.5L/day

Essential Lifestyle Changes

  • Track bowel movement frequency daily
  • Report skin rashes or cough early to oncologist
  • Light exercise
When to Contact a Doctor Urgently:
New onset dry cough or shortness of breath
Severe abdominal cramps with bloody diarrhea
Extreme lethargy

Prevention & Long-Term Health

Baseline thyroid (TSH), liver, and renal function tests before starting each cycle

Frequently Asked Questions

How long can a patient stay on immunotherapy?

Treatment typically continues for up to 2 years if the tumor remains controlled without unacceptable side effects.

Are side effects different from normal chemotherapy?

Yes. Immunotherapy side effects are immune-mediated (inflammation) rather than cytotoxic (hair loss/low counts).
