Stereotactic ablative radiotherapy: a potentially curable approach to early stage multiple primary lung cancer
Open accessAbstract
BACKGROUND: Surgical resection has been the standard treatment for early stage multiple primary lung cancer (MPLC). However, a significant proportion of patients with MPLC cannot undergo surgery. For this report, the authors explored the role of stereotactic ablative radiotherapy (SABR) for patients with MPLC. METHODS: Patients with MPLC who received SABR (50 grays [Gy] in 4 fractions or 70 Gy in 10 fractions) for the second tumor were reviewed. Four-dimensional, computed tomography-based, planning/volumetric image-guided treatment was used for all patients. Treatment outcomes/toxicities were analyzed. RESULTS: For the 101 patients who received SABR, at a median follow-up of 36 months and with a median overall survival (OS) of 46 months, the 2-year and 4-year in-field local control rates were 97.4% and 95.7%, respectively. The 2-year and 4-year OS rates were 73.2% and 47.5%, respectively; and the progression-free survival (PFS) rates were 67% and 58%, respectively. Patients who had metachronous tumors had better OS and PFS than patients who had synchronous tumors (2-year OS: 80.6% metachronous vs 61.5% synchronous; 4-year OS: 52.7% vs 39.7%, respectively; P = .047; 2-year PFS: 84.7% vs 49.4%, respectively; 4-year PFS: 75.6% vs 30.4%, respectively; P = .0001). For patients who either underwent surgery or received SABR for an index tumor, the incidence of grade ≥ 3 radiation pneumonitis was 3% (2 of 71 patients); however, this increased to 17% (5 of 30 patients) for those who received conventional radiotherapy for an index tumor. Other grade ≥ 3 toxicities included grade 3 chest wall pain (3 of 101 patients; 3%) and grade 3 skin toxicity (1 of 101 patients; 1%). CONCLUSIONS: SABR achieves promising long-term tumor control and survival and may be a potential curative treatment for early stage MPLC.

Surgery and stereotactic radiosurgery have been shown to produce long-term survivors in patients with a solitary lesion in the contralateral lung.
“Both surgery [169, 170] and SRS [171, 172] have been shown to result in long-term survivors in this setting [IV, B].”

“the OS for patients who had both a stage I index tumor and a stage I second primary tumor was similar to the OS for patients who had a single, pure stage I primary lung cancer.(20) These results further suggest that MPLC should be treated with curative intent rather than palliation as metastatic disease.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
