Patients with NSCLC staged as T1-2N0 treated with SBRT are aimed for the study. We will include studies in which dose prescription methods and local control rate were described. Articles with at least 25 cases and a median follow-up duration of at least 12 months was included.Articles were published as full reports. Non-English reports will be excluded.The reports are permitted for centrally located tumors, or T3 or T4 tumors consisted of less than 30% of the entire study population.
Articles including metastasis or articles which overall survival and local control rates are not determined on a one-to-one basis will be excluded.
Studies involving patients with metastatic lung tumors, postoperative recurrence or lymph node metastases, or studies restricted to elderly patients are excluded.
The reports were excluded if patients are recruited for a certain property of the tumor or patients characteristics such as pathology, ground-glass opacity, operability, or interstitial pneumonia.
Data that only reported outcomes for specific patient groups (e.g., operable vs. inoperable) or tumor groups (e.g., histologically proven vs. unproven) and for which no overall outcome was given are excluded.
Studies including particle therapy and concurrent chemotherapy are excluded.
Concurrent chemotherapy is not permitted.

Purpose: Local control (LC) is an important outcome of local cancer therapy, besides overall survival (OS). We conducted a comprehensive literature search to investigate whether a high LC rate contributes to good OS in radiotherapy for early-stage non-small cell lung cancer (ES-NSCLC).
Conclusions: Three-year LC was correlated with three-year OS in patients receiving radiotherapy for ES-NSCLC. A 5% increase in 3-year LC is expected to improve the 3-year CSS and OS rates by 3.8% and 2.8%, respectively.

Materials and methods: Studies in patients receiving radiotherapy for peripheral ES-NSCLC, mainly staged as T1-2N0M0 were included for a systematic review. Relevant information was collected including, dose fractionation, T stage, median age, 3-year LC, cancer-specific survival (CSS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and OS. Correlations between outcomes and clinical variables were evaluated.
After screening, 101 data points from 87 studies including 13,435 patients were selected for the quantitative synthesis.
Toxicities of grade 3 or higher were low (3.4%).
Results: After screening, 101 data points from 87 studies including 13,435 patients were selected for the quantitative synthesis. Univariate meta-regression analysis revealed that the coefficients between the 3-year LC and 3-year DFS, DMFS, CSS, and OS were 0.753 (95% confidence interval (CI): 0.307-1.199; p < 0.001), 0.360 (95% CI: 0.128-0.593; p = 0.002), 0.766 (95% CI: 0.489-1.044; p < 0.001), and 0.574 (95% CI: 0.275-0.822; p < 0.001), respectively. Multivariate analysis revealed that the 3-year LC (coefficient, 0.561; 95% CI: 0.254-0.830; p < 0.001) and T1 proportion (coefficient, 0.207; 95% CI: 0.030-0.385; p = 0.012) were significantly associated with the 3-year OS and CSS (coefficient for 3-year LC, 0.720; 95% CI: 0.468-0.972; p < 0.001 and T1 proportion, 0.002; 95% CI: 0.000-0.003; p = 0.012).

This study will be conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses.
Study Search
We will systematically search PubMed on April 1, 2022. The search formula for PubMed is the followings: ((NSCLC OR non-small cell lung cancer OR ((lung OR pulmonary) AND (cancer OR carcinoma OR malignancy OR tumor OR neoplasm OR neoplasms OR carcinomas OR malignancies)) AND ((humans[Filter]) AND (english[Filter]))) AND (SBRT[title] OR SRT[title] OR SABR[title] OR stereotactic[title] AND ((humans[Filter]) AND (english[Filter])))) AND (local control OR local recurrence OR local relapse OR local progression AND ((humans[Filter]) AND (english[Filter]))). Reference lists in the included articles were also checked as hand search.
Data Extraction
Data will be extracted by the two investigators independently and cross-checked.
Data Interpretation
Pearson's or Spearman's correlation coefficient between local control and overall survival rates will be calculated.
