Evidence Based Handbook on Diagnosis and Staging in Oncology

With the rapid expansion of imaging technologies, molecular markers, and onco‑pathological tests, clinicians increasingly face uncertainty about selecting the most appropriate investigations for diagnosing and staging cancer. This lack of clarity often results in under‑ or over‑investigating, leading to delays in initiating timely treatment.This book provides a structured, subsite‑wise—and in some sections, histology‑wise—overview of the ideal investigations required to diagnose, stage, prognosticate, and predict cancer and its treatment responses. It offers evidence based recommendations  (based on sensitivity, specificity, negative predictive value, etc.) and concise guidance that clinicians can readily apply in daily practice. Each chapter outlines the essential investigations needed during post‑treatment follow‑up of cancer patients.The book serves oncology residents across surgical, medical, and radiation oncology, as well as junior and senior faculty seeking to strengthen their investigative approach and apply evidence‑based practices consistently in clinical settings.
