In advanced Renal Cell Carcinoma (aRCC), systemic therapy is the mainstay of treatment, with no or little role for surgery in these patients. Tyrosine kinase inhibitors (TKIs) and immune-oncological (IOs) therapies, either alone or in combination, are recommended in these patients depending on patient and tumour factors. The sequencing of therapies is critical in RCC because the choice of subsequent line therapy is heavily dependent on the response and duration of the previous treatment.

Chemotherapeutic agents, endocrine therapy and radiotherapy used in the management of breast cancer are known to cause decreased bone mineral density, and thus, increased incidence of fractures. A majority (~60%) of the breast cancer patients in India are either estrogen (ER) or progesterone hormone receptor (PR) positive. Adjuvant treatment with aromatase inhibitors (AIs) is the treatment mainstay for hormone-sensitive disease in postmenopausal (PM) women, with reduced bone mineral density (BMD), which results in increased fracture rates.

EGFR-TKIs have changed the landscape of metastatic NSCLC treatment with a significant improvement in survival of EGFRm patients compared to wild-type EGFR. Even with the newer third generation EGFR TKIs like, Osimertinib, which has proven efficacy against the resistance mutation of EGFRm T790M, progression eventually occurs. There are limited treatment options for patients with metastatic EGFRm NSCLC with other acquired resistance.

More than 50% of non-small cell lung cancer (NSCLC) cases harbor an actionable mutation, and molecular testing at different intervals can help in personalized and targeted treatment. Core tissue biopsy and needle biopsy done at the time of diagnosis/disease progression are interventional, time-consuming and can affect the patients adversely. Noninterventional biomarker testing by liquid biopsy promises to revolutionize advanced stage cancer screening.
