Modalitas Diagnostik Tumor Paru Perifer (Diagnostic Modality for Peripheral Lung Tumor)

---

Peripherallung tumor is defined in most studies as tumorthat are not visible beyond the visual segmental bronchi and located >2 cm in all directions around the proximal bronchial tree. Localised peripheral pulmonary tumor is commonly encountered in clinical practice and frequently require tissue diagnosis to project a treatment plan. The investigation of a peripheral lung tumor is a challenging diagnostic problem. Some pulmonologist prefer to diagnose peripheral lung tumor from tissue samples obtained by percutaneous needie aspiration cytology or biopsy. Although success rates of these techniques might be very high, with 76-97% diagnostic accuracy, these techniques have several problems. Flexible fibreoptic bronchoscopy (FFB) as a traditional technique in diagnosing peripheral lung tumor, with diagnostic accuracy at 20-84% for malignant tumors and at 35-56% for benign tumors. Flexible fibreoptic bronchoscopy has a lower diagnostic yield in smaller tumor, detecting only 11-42% of those < 2 cm in diameter under radiographic fluoroscopic guidance. Unfortunately FFB cannot always reach peripherallung tumor, in particular the smaller tumor. Therefore.new guidance techniques like endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB) are now available and used as a diagnostic tool.
