Abstract
BACKGROUND Early-stage lung cancer, primarily treated with surgery, often occur in poor surgical candidates (impaired respiratory function, prior thoracic surgery, severe comorbidities). Stereotactic ablative radiotherapy (SABR) is a non-invasive alternative that provides comparable local control. This technique is particularly relevant for surgically resectable metachronous lung cancer, in patients unable to undergo surgery.. The objective of this study is to evaluate the clinical outcome of patients treated with SABR for stage I metachronous lung cancer (MLC) versus stage I primary lung cancer (PLC). PATIENTS AND METHODS 137 patients treated with SABR for stage I non-small cell lung cancer were retrospectively reviewed, of which 28 (20.4%) were MLC and 109 (79.6%) were PLC. Cohorts were evaluated for differences in overall survival (OS), progression-free survival (PFS), metastasis-free survival, local control (LC), and toxicity. RESULTS After SABR, patients treated for MLC have comparable median age (76.6 vs 78.6, p = 0.2), 3-year LC (83.6% vs. 72.6%, p = 0.2), PFS (68.7% vs. 50.9%, p = 0.9), and OS (78.6% vs. 52.1%, p = 0.9) as PLC, along with similar rates of total (54.1% vs. 42.9%, p = 0.6) and grade 3 + toxicity (3.7% vs. 3.6%, p = 0.9). Previous treatment of MLC patients was either surgery (21/28, 75%) or SABR (7/28, 25%). The median follow-up was 53 months. CONCLUSION SABR is a safe and effective approach for localized metachronous lung cancer.

Pract Radiat Oncol 2021; 12:e110-e116. [PMID: 34861443 DOI: 10.1016/j.prro.2021.11.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Revised: 11/18/2021] [Accepted: 11/19/2021] [Indexed: 11/18/2022]
Abstract
PURPOSE/OBJECTIVES Stereotactic body radiotherapy (SBRT) has increasingly been used to treat early-stage primary lung cancers, but its effectiveness and safety in patients with multiple synchronous primary lung tumors (SPLC) is not as well-established. Our aim was to evaluate clinical outcomes, patterns of recurrence, and toxicities for these patients. METHODS/MATERIALS We queried an institutional database of patients treated with SBRT for primary lung tumors from 2007 to 2019. Patients with known metastatic disease were excluded. Recurrences were described as new primaries (NP) if they occurred as an isolated pulmonary mass outside the previous PTV. RESULTS We analyzed 126 lesions from 60 consecutive patients who received SBRT synchronously to ≥2 lesions for non-metastatic lung cancers. Median total dose per lesion was 50 Gy (range 30-60 Gy), delivered over 3-5 fractions. All but four lesions were treated to a biologically effective dose (BED10) ≥100Gy. The median follow-up time was 47.3 months (IQR 34.1-65.6). Median overall survival (OS) was 46.2 months. Two and 5-year OS for all patients were 70% and 48%, respectively. Median progression-free survival was 26 months (IQR 7.6-32.6), and at the time of data collection 25 patients (42%) had experienced any disease progression. Median time to progression was 36 months: 9 (15%) patients experienced local failure (LF), with 1 and 2-year LF rates of 8% and 13%, respectively. Four patients (7%) experienced regional failure, at 3, 10, 30, and 50 months. Eleven patients (18%) experienced distant failure (DF), with 2-year DF rate of 13%. Thirteen patients (21%) developed NPs, with 2-year NP rate of 15.1%. 14 patients (23%) experienced CTCAE grade ≥2 toxicity, and two patients (3%) experienced CTCAE grade ≥3 toxicity (pneumonitis and hemoptysis). CONCLUSION Synchronous SBRT to BED10 ≥100Gy appears safe and effective for selected patients with SPLC.

Abstract
INTRODUCTION In patients with non-small cell lung cancer (NSCLC) who present with multiple pulmonary nodules, it is often difficult to distinguish metastatic disease from synchronous primary lung cancers (SPLC). We sought to evaluate clinical outcomes after stereotactic body radiotherapy (SBRT) alone to synchronous primary lesions. MATERIAL AND METHODS Patients with synchronous AJCC 8th Edition Stage IA-IIA NSCLC and treated with stereotactic body radiation therapy (SBRT) to all lesions between 2009-2018 were reviewed. SPLC was defined as patients having received two courses of SBRT within 180 days for treatment of separate early stage tumors. In total, 36 patients with 73 lesions were included. Overall survival (OS), progression-free survival (PFS), cumulative incidence of local failure (LF), and regional/distant failure (R/DF) were estimated and compared with a control cohort of solitary early stage NSCLC patients. RESULTS Median PFS was 38.8 months (95% CI 14.3-not reached [NR]); 3-year PFS rates were 50.6% (35.6-72.1). Median OS was 45.9 months (95% CI: 35.9-NR); 3-year OS was 63.0% (47.4-83.8). Three-year cumulative incidence of LF and R/DF was 6.6% (3.7-13.9) and 35.7% (19.3-52.1), respectively. Patients with SPLC were compared to a control group (n = 272) of patients treated for a solitary early stage NSCLC. There was no statistically significant difference in PFS (p = .91) or OS (p = .43). Evaluation of the patterns of failure showed a trend for worse cumulative incidence of R/DF in SPLC patients as compared to solitary early stage NSCLC (p = .06). CONCLUSION SBRT alone to multiple lung tumors with SPLC results in comparable PFS, OS, and LF rates to a cohort of patients treated for solitary early stage NSCLC. Those with SPLC had non-significantly higher R/DF. Patients with SPLC should be followed closely for failure and possible salvage therapy.

[PMID: 33183196 DOI: 10.2174/1389200221999201111193910] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 07/30/2020] [Accepted: 09/22/2020] [Indexed: 12/24/2022]
Abstract
BACKGROUND Cancer is a major problem that threatens human survival and has a high mortality rate. The traditional chemotherapy methods are mainly intravenous injection and oral administration, but have obvious toxic and side effects. Anti-tumor drugs for pulmonary administration can enhance drug targeting, increase local drug concentration, and reduce the damage to systemic organs, especially for the treatment of lung cancer. METHODS The articles on the pharmacokinetics of anti-tumor drugs targeting pulmonary administration were retrieved from the Pub Med database. This article mainly took lung cancer as an example and summarized the pharmacokinetic characteristics of anti-tumor drugs targeting for pulmonary administration contained in nanoparticles, dendrimers, liposomes and micelles. RESULTS The review shows that the pharmacokinetics process of pulmonary administration is associated with a drug carrier by increasing the deposition and release of drugs in the lung, and retarding the lung clearance rate. Among them, the surface of dendrimers could be readily modified, and polymer micelles have favorable loading efficiency. In the case of inhalation administration, liposomes exhibit more excellent lung retention properties compared to other non-lipid carriers. Therefore, the appropriate drug carrier is instrumental to increase the curative effect of anti-tumor drugs and reduce the toxic effect on surrounding healthy tissues or organs. CONCLUSION In the process of pulmonary administration, the carrier-embedded antitumor drugs have the characteristics of targeted and sustained release compared with non-packaging drugs, which provides a theoretical basis for the clinical rational formulation of chemotherapy regimens. However, there is currently a lack of comparative research between drug packaging materials, and more importantly, the development of safe and effective anti-tumor drugs targeting for pulmonary administration requires more data.
