Before a patient's first fraction, the therapist reviews a lung cancer chart containing a chest CT describing a peripheral nodule, a bronchoscopic biopsy identifying adenocarcinoma, a PET report showing no uptake outside the chest, and surgical pathology reporting negative margins with every sampled lymph node negative. Which statement correctly attributes each finding to the report that establishes it?

Each document in a treatment chart answers a different clinical question, and credit depends on knowing which question a document can actually settle. Histologic type comes only from tissue examined under the microscope, so the bronchoscopic biopsy is the record that names the tumor. Margin status and lymph node results are decided when the resected specimen is sampled and examined, which places both findings in the surgical pathology report; the operative note describes what happened in the room and may carry an intraoperative impression, but the final word on margins is histologic. Assigning the tumor type to the chest CT fails because imaging shows anatomy, density and location and never establishes cellular type. Assigning margins and nodes to the PET report fails because metabolic activity speaks to spread and biology rather than the microscopic distance between tumor and cut surface. Treating the operative note as the source of final margins fails because frozen impressions are superseded by definitive pathology. Exam caveat: a preoperative biopsy establishes type but never staging, and nodes seen on imaging are suspicion rather than confirmation. Practical check: before the first fraction, match every value you chart to the single report that owns it.
