Complete resection significantly improves lung cancer survival rates compared to incomplete resection. Preoperative thoracoscopy and tailored postoperative therapies can enhance patient outcomes.

Area of Science:

Oncology
Thoracic Surgery
Cancer Research

Background:

Analysis of reasons and countermeasures for incomplete resection in lung cancer surgery.
Study included 274 patients with primary non-small cell lung cancer over 12 years.

Observation:

Complete resection was performed in 248 patients; incomplete resection in 26.
Three-year survival: 62% for complete resection vs. 17% for incomplete resection.
No survival difference between palliative reduction surgery and exploratory thoracotomy.

Findings:

Incomplete resection in lung cancer leads to significantly poorer survival.
Preoperative thoracoscopic observation can help avoid unnecessary thoracotomies for undetected pleural dissemination or effusion.
Postoperative radiochemotherapy may improve prognosis, especially when guided by chemotherapy sensitivity assays.

Implications:

Complete surgical resection is crucial for improving non-small cell lung cancer prognosis.
Enhanced preoperative diagnostic methods like thoracoscopy are needed for accurate staging.
Personalized postoperative treatment strategies, including chemotherapy based on sensitivity testing, are warranted.
