Precision Lung Cancer Diagnosis Before Treatment Begins
Accurate diagnosis is the foundation of effective lung cancer treatment. Before any treatment decision can be made — surgery, targeted therapy, immunotherapy, or chemotherapy — the cancer must be precisely characterized: its location, stage, histological type, and molecular profile. At Shanghai Chest Hospital, Dr. Chen Zhiwei leads a minimally invasive diagnostic program that gives patients the most accurate possible diagnosis with the least possible discomfort and risk.
Featured Specialist: Dr. Chen Zhiwei (陈智伟)
Dr. Chen Zhiwei is Deputy Director of the Oncology Department at Shanghai Chest Hospital (Shanghai Shi Xiongke Yiyuan) — China's premier dedicated thoracic disease center. He specializes in:
- Early lung cancer diagnosis using advanced minimally invasive techniques
- EBUS-TBNA (Endobronchial Ultrasound-guided Transbronchial Needle Aspiration) — a bronchoscopic technique for sampling mediastinal lymph nodes and central tumors without surgery
- CT-guided percutaneous needle biopsy — precise sampling of peripheral lung nodules under CT imaging guidance
- Individualized comprehensive treatment — chemotherapy and targeted therapy tailored to each patient's molecular profile and clinical situation
Why Accurate Diagnosis Matters So Much in Lung Cancer
Lung cancer treatment has become highly personalized — the right drug for one patient may be completely ineffective for another. Getting the diagnosis right from the start determines everything that follows:
- Histological subtype (adenocarcinoma, squamous cell, small cell, large cell) determines which treatments are appropriate
- Molecular profiling (EGFR, ALK, ROS1, KRAS, MET, RET, HER2, BRAF) identifies targetable driver mutations
- PD-L1 expression guides immunotherapy selection
- Lymph node staging determines whether surgery is appropriate or whether neoadjuvant therapy should come first
- Adequate tissue sampling is essential — insufficient biopsy material can delay or prevent molecular testing
Dr. Chen's expertise in minimally invasive biopsy techniques ensures that patients receive adequate, high-quality tissue samples for comprehensive molecular analysis — without the risks and recovery time of surgical biopsy.
EBUS-TBNA: Staging Without Surgery
Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) is one of the most important advances in lung cancer diagnosis of the past two decades. Dr. Chen is an expert practitioner of this technique:
- A flexible bronchoscope with an ultrasound probe is passed through the mouth into the airways
- Real-time ultrasound imaging allows visualization of lymph nodes and masses adjacent to the airways
- A fine needle is passed through the bronchial wall to sample lymph nodes or tumors under direct ultrasound guidance
- No surgical incision is required — the procedure is performed under conscious sedation or light general anesthesia
- Patients typically recover within hours and can be discharged the same day
- EBUS-TBNA can sample mediastinal lymph nodes that would otherwise require mediastinoscopy (a surgical procedure) to access
- Tissue obtained is sufficient for histological diagnosis, immunohistochemistry, and NGS molecular profiling
CT-Guided Percutaneous Needle Biopsy
For peripheral lung nodules that cannot be reached by bronchoscopy, Dr. Chen performs CT-guided percutaneous needle biopsy:
- The patient lies in the CT scanner while the radiologist or pulmonologist guides a fine needle through the chest wall to the nodule
- Real-time CT imaging ensures millimeter-precise needle placement
- Core needle biopsy provides sufficient tissue for full molecular profiling
- The procedure takes approximately 30–60 minutes and is performed under local anesthesia
- Particularly valuable for small peripheral nodules detected on screening CT
Individualized Treatment: Chemotherapy and Targeted Therapy
Beyond diagnosis, Dr. Chen provides comprehensive individualized treatment for lung cancer patients, including:
- Platinum-based chemotherapy regimens for NSCLC and SCLC, optimized for each patient's performance status and comorbidities
- EGFR-targeted therapy (gefitinib, erlotinib, osimertinib, aumolertinib) for EGFR-mutated NSCLC
- ALK inhibitors (alectinib, brigatinib, lorlatinib) for ALK-rearranged NSCLC
- Anti-angiogenic agents (bevacizumab, anlotinib) in combination with chemotherapy or targeted therapy
- Maintenance therapy strategies to prolong disease control after initial treatment response
- Treatment of brain metastases — CNS-penetrant targeted agents and coordination with radiation oncology
Who Should Consider Consulting Dr. Chen?
- Patients with a lung nodule or mass detected on CT that requires biopsy for diagnosis
- Patients who need mediastinal lymph node staging before surgery or treatment planning
- Patients whose previous biopsy provided insufficient tissue for molecular profiling
- Patients with centrally located tumors or mediastinal involvement requiring EBUS-TBNA
- Patients seeking re-biopsy after disease progression to identify resistance mechanisms
- Patients requiring chemotherapy or targeted therapy coordination alongside diagnostic workup
