From: Rib fracture after stereotactic radiotherapy for primary lung cancer: prevalence, degree of clinical symptoms, and risk factors

 

Lung cancer patients (n = 177)

Mean age (range)

77.3 ± 7.0 (55–92)

Gender (male: female)

132:45

Pathology of the tumor (Ad: SCLC: SCC:spindle cell carcinoma*: unspecified**:unknown***)

89:7:47:1:9:24

Tumor diameter (average ± standard deviation)

8–55 mm(30.0 ± 9.1)

Tumor-chest wall distance (median)

0–53 mm(6)

**Range of follow-up period (median)

  1. Abbreviations: Ad = adenocarcinoma, SCLC = small cell lung cancer, SCC = squamous cell carcinoma, BED = biologically effective dose.
  2. *Suspicious of pleomorphic carcinoma, but a definitive diagnosis was not made because of needle biopsy.
  3. **“unspecified” indicates pathologically definitive non-small cell lung carcinoma, but unspecified for the subtype.
  4. ***“unknown” indicates clinically highly suspicious for lung cancer but no pathology obtained.
