Overall survival in low-comorbidity patients with stage I non-small cell lung cancer who chose stereotactic body radiotherapy compared to surgery. J Thorac Cardiovasc Surg 2024; 167:822-833.e7. [PMID: 37500052 DOI: 10.1016/j.jtcvs.2023.07.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 06/10/2023] [Accepted: 07/12/2023] [Indexed: 07/29/2023]
Abstract
OBJECTIVE To evaluate trends in the utilization of stereotactic body radiotherapy (SBRT) and to compare overall survival (OS) of patients with early-stage non-small cell lung cancer (NSCLC) undergoing SBRT versus those undergoing surgery. METHODS The National Cancer Database was queried for patients without documented comorbidities who underwent surgical resection (lobectomy, segmentectomy, or wedge resection) or SBRT for clinical stage I NSCLC between 2012 and 2018. Peritreatment mortality and 5-year OS were compared among propensity score-matched cohorts. RESULTS A total of 30,658 patients were identified, including 24,729 (80.7%) who underwent surgery and 5929 (19.3%) treated with SBRT. Between 2012 and 2018, the proportion of patients receiving SBRT increased from 15.9% to 26.0% (P < .001). The 30-day mortality and 90-day mortality were higher among patients undergoing surgical resection versus those receiving SBRT (1.7% vs 0.3%, P < .001; 2.8% vs 1.7%, P < .001). In propensity score-matched patients, OS favored SBRT for the first several months, but this was reversed before 1 year and significantly favored surgical management in the long term (5-year OS, 71.0% vs 41.8%; P < .001). The propensity score-matched analysis was repeated to include only SBRT patients who had documented refusal of a recommended surgery, which again demonstrated superior 5-year OS with surgical management (71.4% vs 55.9%; P < .001). CONCLUSIONS SBRT is being increasingly used to treat early-stage lung cancer in low-comorbidity patients. However, for patients who may be candidates for either treatment, the long-term OS favors surgical management.

Surgery 2023; 174:618-625. [PMID: 37391325 DOI: 10.1016/j.surg.2023.05.017] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 03/05/2023] [Accepted: 05/24/2023] [Indexed: 07/02/2023]
Abstract
BACKGROUND Surgery is the only potentially curative treatment for non-metastatic upper gastrointestinal cancers. We analyzed patient and provider characteristics associated with non-surgical management. METHODS We queried the National Cancer Database for patients with upper gastrointestinal cancers from 2004 to 2018 who underwent surgery, refused surgery, or for whom surgery was contraindicated. Multivariate logistic regression identified factors associated with surgery being refused or contraindicated, and Kaplan-Meier curves assessed survival. RESULTS We identified 249,813 patients based on our selection criteria-86.3% had surgery, 2.4% refused, and for 11.3%, surgery was contraindicated. Median overall survival was 48.2 months for patients who underwent surgery versus 16.3 and 9.4 months for the refusal and contraindicated groups. Medical and non-medical factors predicted both surgery refusals and contraindications, such as increasing age (odds ratio = 1.07 and 1.03, respectively, P < .001), Black race (odds ratio = 1.72 and 1.45, P < .001), comorbidities (Charlson-Deyo score 2+, odds ratio = 1.18 and 1.66, P < .001), low socioeconomic status (odds ratio = 1.70 and 1.40, P < .001), no health insurance (odds ratio = 3.26 and 2.34, P < .001), community cancer programs (odds ratio = 1.43 and 1.40, P < .001), low volume facilities (odds ratio = 1.82 and 1.52, P < .001), and stage 3 disease (odds ratio = 1.51 and 6.50, P < .001). On subset analysis (excluding patients age >70, Charlson-Deyo score 2+, and stage 3 cancer), non-medical predictors of both outcomes were similar. CONCLUSION Refusal of and medical contraindications for surgery profoundly impact overall survival. The same factors (ie, race, socioeconomic status, hospital volume, and hospital type) predict these outcomes. These findings suggest variation and potential bias that may exist between physicians and patients discussing cancer surgery.

Abstract
This study aimed to investigate the robustness of a deep learning (DL) fusion model for low training-to-test ratio (TTR) datasets in the segmentation of gross tumor volumes (GTVs) in three-dimensional planning computed tomography (CT) images for lung cancer stereotactic body radiotherapy (SBRT). A total of 192 patients with lung cancer (solid tumor, 118; part-solid tumor, 53; ground-glass opacity, 21) who underwent SBRT were included in this study. Regions of interest in the GTVs were cropped based on GTV centroids from planning CT images. Three DL models, 3D U-Net, V-Net, and dense V-Net, were trained to segment the GTV regions. Nine fusion models were constructed with logical AND, logical OR, and voting of the two or three outputs of the three DL models. TTR was defined as the ratio of the number of cases in a training dataset to that in a test dataset. The Dice similarity coefficients (DSCs) and Hausdorff distance (HD) of the 12 models were assessed with TTRs of 1.00 (training data: validation data: test data = 40:20:40), 0.791 (35:20:45), 0.531 (31:10:59), 0.291 (20:10:70), and 0.116 (10:5:85). The voting fusion model achieved the highest DSCs of 0.829 to 0.798 for all TTRs among the 12 models, whereas the other models showed DSCs of 0.818 to 0.804 for a TTR of 1.00 and 0.788 to 0.742 for a TTR of 0.116, and an HD of 5.40 ± 3.00 to 6.07 ± 3.26 mm better than any single DL models. The findings suggest that the proposed voting fusion model is a robust approach for low TTR datasets in segmenting GTVs in planning CT images of lung cancer SBRT.

Modeling the COVID Pandemic: Do Delays in Surgery Justify Using Stereotactic Radiation to Treat Low-Risk Early Stage Non-Small Cell Lung Cancer? J Surg Res 2023; 283:532-539. [PMID: 36436290 PMCID: PMC9686123 DOI: 10.1016/j.jss.2022.10.081] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2022] [Revised: 08/02/2022] [Accepted: 10/08/2022] [Indexed: 11/25/2022]
Abstract
INTRODUCTION It was suggested that stereotactic radiation (SBRT) is an "alternative if no surgical capacity is available" for non-small cell lung cancer (NSCLC) care during the COVID-19 pandemic. The purpose of this study was to compare the oncologic outcomes of delayed surgical resection and early SBRT among operable patients with early stage lung cancer. METHODS The National Cancer Database was queried for patients with cT1aN0M0 NSCLC who underwent surgery or SBRT (2010-2016) with no comorbidity. Patients with any comorbidities or age >80 were excluded. The outcome of interest was overall survival. Delays in surgical care were modeled using different times from diagnosis to surgery. A 1:1 propensity match was performed and survival was analyzed using multivariable Cox regression. RESULTS Of 6720 healthy cT1aN0M0 NSCLC patients, 6008 (89.4%) received surgery and 712 (10.6%) received SBRT. Among surgery patients, time to surgery >30 d was associated with inferior survival (HR > 1.4, P ≤ 0.013) compared with patients receiving surgery ≤14 d. Relative to SBRT, surgery demonstrated superior survival at all time points evaluated: 0-30 d, 31-60 d, 61-90 d, and >90 d (all P < 0.001). Among a propensity-matched cohort of 256 pairs of patients, delayed surgery (>90 d) remained association with better overall survival relative to early SBRT (5-year survival 76.9% versus 32.3%, HR = 0.266, P < 0.001). CONCLUSIONS Although longer time to surgery is associated with inferior survival among surgery patients, delayed surgery is superior to early SBRT. Surgical resection should remain the standard of care to treat operable early stage lung cancer despite delays imposed by the COVID-19 pandemic.

Abstract
Background Clinical decision-making for patients with stage I lung cancer is complex. It involves multiple options [lobectomy, segmentectomy, wedge, stereotactic body radiotherapy (SBRT), thermal ablation], weighing multiple outcomes (e.g., short-, intermediate-, long-term) and multiple aspects of each (e.g., magnitude of a difference, the degree of confidence in the evidence, and the applicability to the patient and setting at hand). A structure is needed to summarize the relevant evidence for an individual patient and to identify which outcomes have the greatest impact on the decision-making. Methods A PubMed systematic review from 2000-2021 of outcomes after SBRT or thermal ablation vs. resection is the focus of this paper. Evidence was abstracted from randomized trials and non-randomized comparisons with at least some adjustment for confounders. The analysis involved careful assessment, including characteristics of patients, settings, residual confounding etc. to expose degrees of uncertainty and applicability to individual patients. Evidence is summarized that provides an at-a-glance overall impression as well as the ability to delve into layers of details of the patients, settings and treatments involved. Results Short-term outcomes are meaningfully better after SBRT than resection. SBRT doesn't affect quality-of-life (QOL), on average pulmonary function is not altered, but a minority of patients may experience gradual late toxicity. Adjusted non-randomized comparisons demonstrate a clinically relevant detriment in long-term outcomes after SBRT vs. surgery. The short-term benefits of SBRT over surgery are accentuated with increasing age and compromised patients, but the long-term detriment remains. Ablation is associated with a higher rate of complications than SBRT, but there is little intermediate-term impact on quality-of-life or pulmonary function tests. Adjusted comparisons show a meaningful detriment in long-term outcomes after ablation vs. surgery; there is less difference between ablation and SBRT. Conclusions A systematic, comprehensive summary of evidence regarding Stereotactic Body Radiotherapy or thermal ablation vs. resection with attention to aspects of applicability, uncertainty and effect modifiers provides a foundation for a framework for individualized decision-making.

Abstract
Objectives Stereotactic body radiation therapy (SBRT) is an established primary treatment modality in patients with lung cancer who have multiple comorbidities and/or advanced-stage disease. However, its role in otherwise healthy patients with stage I lung cancer is unclear. In this context, we compared the effectiveness of SBRT versus surgery on overall survival using a national database. Methods We identified all patient with clinical stage I non–small cell lung cancer from the National Cancer Database from 2004 to 2016. We defined otherwise healthy patients as those with a Charlson-Deyo comorbidity index of 0 and whose treatment plan included options for either SBRT or surgery. We further excluded patients who received SBRT due to a contraindication to surgery. We first used propensity score matching and Cox proportional hazard models to identify associations. Next, we fit 2-stage residual inclusion models using an instrumental variables approach to estimate the effects of SBRT versus surgery on long-term survival. We used the hospital SBRT utilization rate as the instrument. Results Of 25,963 patients meeting all inclusion/exclusion criteria, 5465 (21%) were treated with SBRT. On both Cox proportional hazards modeling and propensity-score matched Kaplan-Meier analysis, surgical resection was associated with improved survival relative to SBRT. In the instrumental-variable–adjusted model, SBRT remained associated with decreased survival (hazard ratio, 2.64; P < .001). Both lobectomy (hazard ratio, 0.17) and sublobar resections (hazard ratio, 0.28) were associated with improved overall survival compared with SBRT (P < .001). Conclusions In otherwise healthy patients with stage I NSCLC, surgical resection is associated with a survival benefit compared with SBRT. This is true for both lobar and sublobar resections.

Abstract
Due to the demographic change prevailing in Germany, the age pyramid is shifting more and more upwards. According to the WHO, a patient over the age of 75 is considered to be old. Whether or not and to what extent an old patient can tolerate thoracic surgery purely based on his age and comorbidities remains unclear. Under most circumstances the surgeon's experience seems to be crucial in this decision. PATIENTS AND METHODS: The data analysis included data from 01. 2016-01. 2018 based on the German Thorax Register (Project ID: 2017-03), which was set up under the patronage of the German Society for Anesthesiology and Intensive Care Medicine (DGAI) and the German Society for Thoracic Surgery (DGT). A total of 1357 patients were included, 658 patients had histologically proven lung cancer stage I-II. These were divided into three groups according to their age; group I (< 65 years), group II (65- ≤ 75) years and group III (> 75 years). We were able to show that group III had essentially no increased postoperative complication rates (all = 48.00 %; group I = 40.90 %; group II = 53.00 %; group III = 52.90 %) and even performed better than group II (65 to ≤ 75) regarding pulmonary complications. (postoperative pneumonia group II = 19.20 %, group III = 12.90 %) The mortality was lowest in patients who were operated on in centers of the German Thorax Register (all = 1.70 %, group I = 1.90 %; group II = 1.70 %; group III = 1.30 %), compared to national german average. (all = 1.99 %; group I = 1.23 %; group II = 2.18 %; group III = 3.78 %) In particular, patients of group III showed the greatest difference. Furthermore, we saw that the majority of anatomical resections performed in centers of the German Thorax Register were resected by VATS (Video-assisted Thoracoscopic Surgery) as opposed to patients operated on in hospitals not affiliated with the German Thorax Register. DISCUSSION: Considering these results, the question arises whether in Germany all old patients were treated according to current guidelines. Although there is a certain selection bias in group III, operative candidates fit for surgery are operated in the centers of the German Thorax Register. Our results permit us to conclude that this group of patients should be given optimal surgical therapy when indicated. Age alone should not be the sole determining factor in decision-making regarding thoracic surgery.

Strahlenther Onkol 2021; 198:110-122. [PMID: 34255094 PMCID: PMC8789716 DOI: 10.1007/s00066-021-01811-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Accepted: 06/18/2021] [Indexed: 11/26/2022]
Abstract
PURPOSE The aim of this study was to evaluate the safety and long-term tumor control after stereotactic radiotherapy (SRT) with 12 × 6 Gy of patients with primary bronchial carcinoma (BC) or with pulmonary metastases (MET) of various solid tumors. Local progression-free survival (LPFS), progression-free survival (PFS), overall survival (OS), and prognostic factors were compared. METHODS Between May 2012 and January 2020, 168 patients with 206 pulmonary lesions (170 MET and 36 primary BC) were treated with 12 × 6 Gy (BED10 116 Gy). The irradiated pulmonary MET were from the following cancers: 47 (27.6%) head and neck, 37 (21.8%) rectum or colon, 30 (17.6%) bronchial, 13 (7.6%) malignant melanoma, 9 (5.3%) esophageal, 9 (5.3%) sarcoma, and 25 (14.8%) other. RESULTS The median follow-up was 16.26 months (range: 0.46-89.34) for BC and 19.18 months (0.89-91.11) for MET. Survival rates at 3 years were: OS 43% for BC and 35% for MET; LPFS BC 96% and MET 85%; PFS BC 35% and MET 29%. The most frequently observed grade 3 adverse events (AEs) were pneumonitis (5.9% BC, 4.8% MET), pulmonary fibrosis (2.9% BC, 4% MET), and pulmonary embolism (2.9% BC, 0.8% MET). The favorable prognostic effects on overall survival of patients with MET were female gender (log-rank: p < 0.001), no systemic progression (log-rank; p = 0.048, multivariate COX regression p = 0.039), and malignant melanoma histology (log-rank; p = 0.015, multivariate COX regression p = 0.020). For patients with BC, it was tumor location within the lower lobe (vs. upper lobe, log-rank p = 0.027). LPFS of patients with metastatic disease was beneficially influenced by female gender (log-rank: p = 0.049). CONCLUSION The treatment concept of 12 × 6 Gy is associated with 96% local progression-free survival for BC and 85% for pulmonary metastases after 3 years. There was no difference in response after SRT of primary lung carcinoma or pulmonary metastases.

Clin Oncol (R Coll Radiol) 2021; 33:627-637.

Abstract
AIMS To report late toxicity and long-term outcomes of intensity-modulated radiotherapy (IMRT)-based stereotactic ablative body radiotherapy (SABR) in patients with ultra-central lung tumours. MATERIALS AND METHODS This is a single-institution retrospective analysis of patients treated with SABR for ultra-central tumours between May 2008 and April 2016. Ultra-central location was defined as tumour (GTV) abutting or involving trachea, main or lobar bronchi. Respiratory motion management and static-field dynamic-IMRT were used, with dose prescribed homogeneously (maximum <120%). Descriptive analysis, Kaplan-Meier method, log-rank test and Cox regression were used to assess outcomes. RESULTS Sixty-five per cent of patients had inoperable primary non-small cell lung cancer and 35% had lung oligometastases. The median age was 72 (range 34-85) years. The median gross tumour volume and planning target volume (PTV) were 19.6 (range 1.7-203.3) cm3 and 57.4 (range 7.7-426.6) cm3, respectively. The most commonly used dose fractionation was 60 Gy in eight fractions (n = 51, 87.8%). Median BED10 for D98%PTV and D2%PTV were 102.6 Gy and 115.06 Gy, respectively. With a median follow-up of 26.5 (range 3.2-100.5) months, fatal haemoptysis occurred in five patients (8.7%), of which two were directly attributable to SABR. A statistically significant difference was identified between median BED3 for 4 cm3 of airway, for patients who developed haemoptysis versus those who did not (147.4 versus 47.2 Gy, P = 0.005). At the last known follow-up, 50 patients (87.7%) were without local recurrence. Freedom from local progression at 2 and 4 years was 92 and 79.8%, respectively. The median overall survival was 34.3 (95% confidence interval 6.1-61.6) months. Overall survival at 2 and 4 years was 55.1 and 41.2%, respectively. CONCLUSION In patients with high-risk ultra-central lung tumours, IMRT-based SABR with homogenous dose prescription achieves high local control, similar to that reported for peripheral tumours. Although fatal haemoptysis occurred in 8.7% of patients, a direct causality with SABR was evident in only 3%. Larger studies are warranted to ascertain factors associated with outcomes, especially toxicity, and identify patients who would probably benefit from this treatment.

Abstract
In the past two decades, there has been a steady increase in the use of stereotactic body radiotherapy (SBRT) as an alternative to surgical intervention for early-stage non-small cell lung cancer (NSCLC) patients; however, not much is known about the impact of race and socioeconomic status (SES) on the delivery of SBRT. Here, we conduct a narrative review to examine potential disparities in the use of SBRT. Keyword searches of MEDLINE/PubMed, Web of Science, Embase, and Google Scholar databases were performed for studies focused on race, SES, and the use of SBRT published between 2000 and 2020. Six studies were identified, and showed that minority patients, especially Blacks, were less likely to receive SBRT and had a significantly longer median time between diagnosis to SBRT treatment. Patients with lower income or lower education, as well as those from lower socioeconomic regions were less likely to receive SBRT; they were more likely to receive conventionally fractionated external beam radiation (CFRT) or no treatment. These racial and socioeconomic factors were associated with worse survival in other general early-stage NSCLC studies. In conclusion, the limited number of published studies suggest significant disparities in the treatment of early-stage NSCLC with SBRT. These factors potentially lead to worse survival outcomes among vulnerable patient populations. Equal access to SBRT should be a focus of healthcare delivery systems, to ensure optimal clinical outcomes for patients with early-stage NSCLC.

Abstract
Background The effects of transthyretin (TTR) over-expression on the proliferation and cell cycle of non-small cell lung cancer (NSCLC) A549 cells and its possible mechanism were verified. Methods A total of 196 LC patients and 20 healthy controls were enrolled at Tianjin Hospital, Tianjin, China between Apr 2017 and Oct 2017. The serum TTR content was detected by ELISA. Through lentiviral transfection method, NSCLC cells were divided into non-transfected group (group A), negative control group (group B) transfected with empty vector and experimental group (group C) transfected with TTR over-expression. Cell proliferation was detected by CCK-8 method, TTR mRNA expression was detected by real-time quantitative polymerase chain reaction (RT-qPCR), and TTR protein expression was tested by Western blot (WB). Cell cycle was detected by flow cytometry, Wnt3a/β-catenin protein expression was detected by WB, and mRNA expression was detected by RT-qPCR. Results The serum TTR content in early, middle and late LC group was remarkably lower than that in healthy group (P<0.05). Compared with late stage, TTR content in early and middle stages of LC group was higher, and the difference was statistically marked (P < 0.05). The absorbance value of group C was lower than that of groups A and B, indicating that the cell proliferation activity dramatically decreased, with statistically marked difference (P<0.05). LC A549 cells in group C were obviously blocked in G2M, with statistical significance (P<0.05). Conclusion TTR over-expression can inhibit the proliferation of NSCLC A549 cells, and the expression is related to Wnt3a/β-catenin pathway. TTR in serum of patients was helpful for diagnosing LC and has certain clinical value.

Abstract
Pulmonary carcinosarcoma is a rare lung tumor accounting for <1% of primary lung cancers, characterized by biphasic components with both carcinomatous and sarcomatous mesenchymal features. This report describes a case of pulmonary carcinosarcoma in an octogenarian who was treated with stereotactic body radiation therapy (SBRT) and whose therapeutic response was sustained for 2 years. Along with other treatment modalities, SBRT might be considered for the treatment of medically inoperable localized stage pulmonary carcinosarcoma.

Abstract
INTRODUCTION Stereotactic body radiotherapy (SBRT) has been shown to result in excellent disease control rates for early-stage non-small-cell lung cancer (NSCLC). It remains unknown which patients would most benefit from SBRT in treating NSCLC. PATIENTS AND METHODS We conducted a retrospective analysis of 346 patients treated with SBRT for early-stage NSCLC at 2 institutions (86 patients from City of Hope National Medical Center and 260 patients from The Newport Beach Radiosurgery Center/Hoag Hospital) from February 2010 to July 2019. The primary endpoint was overall survival (OS). The omnibus test of model coefficients was performed to study the associations between clinical factors and OS. Survival analyses were performed by the log-rank test and Cox proportional hazards regression. RESULTS Under the univariate analysis, variables associated with a decreased likelihood of death included age < 65 years (P = .040) and being a surgical candidate (P = .010). Multivariate analysis found that surgical candidates still had a significantly decreased likelihood of death compared to nonsurgical candidates (Hazard ratio 0.360, 95% confidence interval 0.153-0.848, P = .019). Median OS was significantly increased for surgical candidates versus nonsurgical candidates (83 vs 53 months, P = .017). The local failure rate was 9.1%, the locoregional failure rate was 12.7%, and the distant failure rate was 10.7%. CONCLUSION Patients who are deemed to be candidates for surgery have improved OS compared to those who are not when treated with SBRT. This raises the question of selection bias in trials comparing surgery with SBRT in NSCLC, as patients who are deemed to be surgical candidates and then go on to undergo surgery may have an inherent OS benefit.

Abstract
Background Thousands of cancer surgeries were delayed during the peak of the COVID-19 pandemic. This study examines if surgical delays impact survival for breast, lung and colon cancers. Methods PubMed/MEDLINE, EMBASE, Cochrane Library and Web of Science were searched. Articles evaluating the relationship between delays in surgery and overall survival (OS), disease-free survival (DFS) or cancer-specific survival (CSS) were included. Results Of the 14,422 articles screened, 25 were included in the review and 18 (totaling 2,533,355 patients) were pooled for meta-analyses. Delaying surgery for 12 weeks may decrease OS in breast (HR 1.46, 95%CI 1.28–1.65), lung (HR 1.04, 95%CI 1.02–1.06) and colon (HR 1.24, 95%CI 1.12–1.38) cancers. When breast cancers were analyzed by stage, OS was decreased in stages I (HR 1.27, 95%CI 1.16–1.40) and II (HR 1.13, 95%CI 1.02–1.24) but not in stage III (HR 1.20, 95%CI 0.94–1.53). Conclusion Delaying breast, lung and colon cancer surgeries during the COVID-19 pandemic may decrease survival. Delaying cancer surgeries during the COVID-19 pandemic may impact survival. Surgical delays of 12 weeks decreases survival in breast, lung and colon cancers. Surgical delays worsen survival in stage I and II breast cancers but not stage III.

Abstract
The extraordinary demands of managing the COVID-19 pandemic has disrupted the world's ability to care for patients with thoracic malignancies. As a hospital's COVID-19 population increases and hospital resources are depleted, the ability to provide surgical care is progressively restricted, forcing surgeons to prioritize among their cancer populations. Representatives from multiple cancer, surgical, and research organizations have come together to provide a guide for triaging patients with thoracic malignancies as the impact of COVID-19 evolves as each hospital.
