expertise
Oligometastatic Cancer

Oligometastatic cancer represents a biologically distinct state where cancer has spread to only a limited number of distant sites and may still be amenable to treatment with curative or long-term disease-control intent. Dr. Swaroop Revannasiddaiah specialises in evaluating and managing oligometastatic disease using a combination of systemic therapy and targeted local treatment including SABR, tailored to the specific tumour type, number of metastases, and pace of spread. His approach focuses on identifying which patients with Stage IV cancer can benefit from this aggressive combined strategy and guiding them through a structured, evidence-based treatment pathway.

expertise
Oligometastatic Breast Cancer - Diagnosis and Combined Modality Treatment

Oligometastatic breast cancer is Stage IV disease with one to five distant metastatic sites where aggressive combined modality treatment can produce outcomes significantly better than systemic therapy alone. The OLIGOMA trial (ESTRO 2026) demonstrated that adding SABR to standard systemic therapy nearly doubles median progression-free survival. Dr Swaroop Revannasiddaiah provides evaluation and treatment planning for oligometastatic breast cancer at NiSH Clinic, Jayanagar, Bengaluru, integrating CDK4/6 inhibitors, antibody-drug conjugates, and hormone therapy alongside SABR directed at every visible metastatic site, with multidisciplinary tumour board review and management of oligoprogression events to preserve effective systemic therapy.

Phone: +91 9731174360.

expertise
SABR (Stereotactic Ablative Body Radiotherapy) for Breast Cancer Metastases

SABR is a precise outpatient radiation technique delivering ablative doses to metastatic tumours in one to five sessions, using sub-millimetre targeting with real-time image guidance to spare surrounding healthy tissue. In oligometastatic breast cancer, SABR eradicates visible metastatic sites while systemic therapy continues to control microscopic disease. Dr Swaroop Revannasiddaiah coordinates SABR for breast cancer metastases at NiSH Clinic, Jayanagar, Bengaluru, in conjunction with the radiation oncology team. His role encompasses patient selection, systemic therapy optimisation around the SABR course, management of oligoprogression events using SABR to preserve targeted therapy as supported by the AVATAR study, and long-term oncological follow-up with adaptive imaging surveillance.

expertise
Oligometastatic Lung Cancer Treatment (SBRT/SABR)

Oligometastatic lung cancer, defined as non-small cell lung cancer that has spread to a maximum of five distant sites in up to three organs, represents an intermediate disease state where curative-intent local treatment using SBRT (Stereotactic Body Radiotherapy) combined with systemic therapy can produce outcomes previously considered impossible in Stage IV disease. The fundamental principle is that cancer biology, not just staging, determines who benefits: molecular profiling, PET imaging, and tumour board assessment identify the patients whose disease pattern and molecular drivers make them candidates for this aggressive approach. Dr. Swaroop Revannasiddaiah, DM Medical Oncologist with ESMO Certification and Thoracic Oncology Certification from the University of Michigan, leads individualised oligometastatic lung cancer evaluation and treatment at NiSH Clinic, Jayanagar, Bengaluru, coordinating systemic and local therapy in a multidisciplinary framework aimed at maximising the window of disease-free survival.

What is oligometastatic lung cancer and how is it different from fully metastatic Stage IV disease?

Oligometastatic lung cancer is a specific state of Stage IV non-small cell lung cancer in which the disease has spread beyond the lungs and nearby lymph nodes, but only to a limited number of distant sites, defined by the IASLC as a maximum of five distant metastatic spots in up to three organs. This sounds like a technical distinction, but it is a biologically meaningful one. Some lung cancers lack the genetic machinery to spread widely and efficiently. They escape the primary tumour and enter the bloodstream, but they can only establish themselves in one or two highly specific locations: a single adrenal gland nodule, two spots in the brain, a bone metastasis. Before the era of high-resolution molecular PET scanning, we could not identify these patients reliably, because the scans were not sensitive enough to confirm that the few visible spots truly represented all the disease rather than the visible tip of a widely disseminated iceberg. Today, molecular PET imaging can map disease distribution with a precision that changes the clinical decision. In my practice at NiSH Clinic, Jayanagar, Bengaluru, the distinction between oligometastatic and fully metastatic disease determines whether we treat with palliative intent (controlling disease and maintaining quality of life for as long as possible) or curative intent (using aggressive local therapy to eradicate all visible disease combined with systemic therapy to address the microscopic disease). That distinction matters enormously for the patient sitting across the desk from me.

Can CDK4/6 inhibitors and antibody-drug conjugates be combined with SABR?

CDK4/6 inhibitors and antibody-drug conjugates can be combined with SABR. Systemic therapy controls microscopic disease throughout the body while SABR eradicates visible metastatic sites. CDK4/6 inhibitors are typically continued around the SABR course. The exact sequencing is determined by the multidisciplinary team based on the patient's disease, systemic therapy response, and the sites being treated. This coordinated two-pronged approach is the standard strategy for appropriately selected oligometastatic breast cancer patients.

Phone: +91 9731174360.

How many sessions does SABR take and what side effects should patients expect?

SABR delivers a high ablative dose to a metastatic tumour in one to five outpatient sessions, with no admission and no surgical recovery. Each session takes 30 to 90 minutes. Side effects are site-dependent and generally mild. Liver SABR may cause brief fatigue; lung SABR occasionally produces a transient local reaction. The OLIGOMA trial confirmed that adding SABR to systemic therapy caused no major detrimental effect on patients' quality of life.

Phone: +91 9731174360.

What is the difference between oligometastatic breast cancer and Stage IV breast cancer?

All oligometastatic breast cancer is Stage IV, but not all Stage IV breast cancer is oligometastatic. Oligometastatic disease is defined as cancer that has spread to a strictly limited number of distant sites, typically one to five lesions on imaging. This distinction matters clinically: in widespread Stage IV disease, treatment aims at control. In oligometastatic disease, aggressive local treatment alongside systemic therapy can eradicate all visible disease and, in selected patients, produce a functional cure.
