Specialized Care for Pulmonary Nodules and Early Lung Cancer in Shanghai
The widespread adoption of low-dose CT screening has led to a dramatic increase in the detection of pulmonary nodules — small spots on the lung that may or may not represent early cancer. For patients who discover a nodule on a routine scan, the questions are immediate and anxiety-provoking: Is it cancer? Does it need surgery? How much lung will be removed? At Shanghai Chest Hospital, Dr. Sun Yihua leads a dedicated pulmonary nodule program that answers these questions with precision — and operates with a philosophy of doing as little as necessary, and no more.
Featured Specialist: Dr. Sun Yihua (孙艺华)
Dr. Sun Yihua is a senior thoracic surgeon at Shanghai Chest Hospital (Shanghai Shi Xiongke Yiyuan), affiliated with Shanghai Jiao Tong University School of Medicine. She has established a dedicated Pulmonary Nodule Disease Center at Songjiang Hospital — bringing specialized nodule evaluation and early lung cancer surgery to patients in Shanghai's Songjiang district and surrounding areas.
Dr. Sun's clinical philosophy is built on translating cutting-edge research directly into patient care:
- Minimally invasive surgery as the primary approach for early lung cancer — VATS and uniportal techniques that minimize trauma and accelerate recovery
- Selective lymph node dissection — avoiding unnecessary removal of uninvolved lymph nodes, consistent with the latest evidence showing that over-dissection damages immune function without improving outcomes
- Individualized nodule management — not every nodule requires immediate surgery; Dr. Sun applies evidence-based criteria to determine the optimal timing and approach for each patient
- Translational research application — actively incorporating the latest scientific findings into clinical decision-making
Understanding Pulmonary Nodules
A pulmonary nodule is a small rounded opacity on CT imaging, typically less than 3 cm in diameter. The vast majority are benign — caused by old infections, inflammation, or other non-cancerous processes. However, some nodules represent early-stage lung cancer, and distinguishing between them requires expertise:
- Solid nodules: Appear as dense white spots; risk depends on size, shape, and growth rate
- Ground-glass opacity (GGO) nodules: Appear as hazy, semi-transparent areas; often represent early adenocarcinoma in situ or minimally invasive adenocarcinoma
- Part-solid nodules: Have both solid and ground-glass components; higher malignancy risk than pure GGO
- Multiple nodules: Require careful evaluation to determine if they represent multifocal primary lung cancer, metastases, or benign disease
The Pulmonary Nodule Disease Center: A Dedicated Pathway
Dr. Sun's dedicated Pulmonary Nodule Disease Center at Songjiang Hospital provides a structured, evidence-based pathway for nodule evaluation:
- Comprehensive CT analysis: Size, density, morphology, growth rate assessment using standardized protocols
- Risk stratification: Application of validated risk models (Lung-RADS, Fleischner Society guidelines) to determine malignancy probability
- Multidisciplinary discussion: Complex cases reviewed by thoracic surgery, pulmonology, radiology, and pathology
- Surveillance vs. intervention decision: Clear, evidence-based recommendations on whether to monitor, biopsy, or proceed to surgery
- Minimally invasive resection when surgery is indicated, with maximum lung tissue preservation
Minimally Invasive Surgery for Early Lung Cancer
When surgery is indicated, Dr. Sun performs the full range of minimally invasive thoracic procedures:
- Uniportal VATS (single-incision) — the most minimally invasive approach, with a single small incision typically less than 3 cm
- Multiportal VATS — for more complex anatomical resections
- Anatomical segmentectomy — removal of a specific lung segment rather than a full lobe, preserving maximum lung function for tumors ≤2 cm
- Wedge resection — for very small peripheral nodules or patients with limited pulmonary reserve
- Lobectomy — when oncologically required for larger or more centrally located tumors
- Selective lymph node dissection — guided by intraoperative assessment, avoiding unnecessary dissection of uninvolved nodal stations
Why Avoiding Unnecessary Lymph Node Dissection Matters
Dr. Sun's approach to lymph node management reflects the latest evidence in thoracic oncology. Traditional radical lymph node dissection — removing all accessible lymph nodes regardless of involvement — was once standard practice. Emerging research, including work from FUSCC colleagues, has shown that:
- Uninvolved lymph nodes serve as important immune surveillance stations
- Their unnecessary removal disrupts regional immune function
- For early-stage tumors with low nodal metastasis risk, selective dissection achieves equivalent oncological outcomes with less immune disruption
- Reduced dissection also lowers the risk of postoperative complications including chylothorax and prolonged air leak
Who Should Consider Consulting Dr. Sun?
- Patients with a pulmonary nodule detected on CT who want expert evaluation of malignancy risk
- Patients with ground-glass opacity (GGO) nodules requiring specialized management
- Patients with multiple pulmonary nodules needing comprehensive evaluation
- Patients with early-stage lung cancer (Stage I–II) seeking minimally invasive surgical treatment
- Patients who want a second opinion on whether surgery is necessary for their nodule
- Patients in Songjiang or surrounding areas seeking access to Shanghai Chest Hospital expertise locally
How CMCS Coordinates Your Care
China Medical Concierge Shanghai (CMCS) is a health management company — not a hospital. We connect international patients with Shanghai's leading thoracic specialists, including Dr. Sun Yihua at Shanghai Chest Hospital, and manage every step of the process:
- Review of existing CT imaging and prior nodule evaluation reports
- Consultation scheduling at Shanghai Chest Hospital or the Songjiang Pulmonary Nodule Center
- Coordination of additional imaging (PET-CT, high-resolution CT) or biopsy if needed
- Medical interpretation during consultations and surgical planning discussions
- Logistics support: accommodation, visa assistance, and local transport
- Post-surgical follow-up and remote monitoring coordination
