The role of surgery for stage I non-small cell lung cancer in octogenarians in the era of stereotactic body radiotherapy in the Netherlands

ObjectivesResection is the standard treatment for stage I non-small cell lung cancer (NSCLC) in operable patients. Stereotactic body radiotherapy (SBRT) is recommended for inoperable patients. A shift from surgery to SBRT is expected in elderly patients due to increased frailty and competing risks. We assessed the current influence of age on treatment decision-making and overall survival (OS).Materials and methodsWe performed a retrospective cohort study using data from patients with clinical stage I NSCLC diagnosed in 2012–2016 and treated with lobectomy, segmentectomy, wedge resection, or SBRT, retrieved from the Netherlands Cancer Registry. Patient characteristics and OS were compared between SBRT and (sub)lobar resection for patients aged 18−79 and ≥80 years.Results and Conclusion8764 patients treated with lobectomy (n = 4648), segmentectomy (n = 122), wedge resection (n = 272), or SBRT (n = 3722) were included. In 2012–2016, SBRT was increasingly used for octogenarians and younger patients from 75.3% to 83.7% and from 30.8% to 43.2%, respectively. Five-year OS in the whole population was 70% after surgery versus 39% after SBRT and 50% versus 27% in octogenarians. After correction for age, gender, year of diagnosis, and clinical T-stage, OS was equal after lobectomy and SBRT in the first 2 years after diagnosis. However, after >2 years, OS was better after lobectomy than after SBRT.SBRT is the prevailing treatment in octogenarians with stage I NSCLC. While surgery is associated with better OS than SBRT, factors other than treatment modality (e.g. comorbidity) may have had a significant impact on survival. The wider application of SBRT in octogenarians likely reflects the frailty of this group. Registries and trials are required to identify key determinants of frailty in this specific population to improve patient selection for surgery or SBRT.Stem cells & developmental biolog

Impact of health care organization on surgical lung cancer care

ObjectivesOrganization and governance of national healthcare might play an important role in decision-making and outcomes in patients with lung cancer. Both Denmark and the Netherlands have a high level of healthcare but a different financial coverage, governance and level of centralization. By using both national databases we analyzed the consequences of these differences on patterns of care and outcomes with a focus on morbidity, mortality and clinical staging.Materials and methodsGeneral numbers on both healthcare systems were requested. All patients who had surgery for lung cancer from 2013 to 2016 were included. Mortality, morbidity and clinical staging were analyzed for patients with NSCLC without metastases, only one operation and no neo-adjuvant therapy.ResultsIn 2016 annual budget as share of gross national product was 10.4% for both countries. In Denmark 4 hospitals performed lung surgery in 2016, compared to 43 hospitals in the Netherlands. We included 4030 Danish and 8286 Dutch patients. In the subgroup 30-day mortality was 1.5% in Denmark compared to 1.9% in the Netherlands. The percentage of patients with a complicated course was 24.4% and 34.8% respectively (p ConclusionSurgery for lung cancer is at a high level in both countries, reflected by low mortality-rates. Centralization has been implemented successfully in Denmark, which might explain the lower rate of patients with a complicated post-operative course, although different definitions preclude firm conclusions. In both countries correct clinical staging of lung cancer remains a challenge.</div

Feasibility of salvage resection following locoregional failure after chemoradiotherapy and consolidation durvalumab for unresectable stage III non-small cell lung cancer

Introduction: In patients with unresectable stage III non-small cell lung cancer, high-dose chemoradiotherapy (CRT) followed by consolidation durvalumab improves the 5-year overall survival compared to CRT alone. The feasibility and safety of salvage surgery for such patients who subsequently develop locoregional failure (LRF) is unclear. We evaluated our institutional experience with radical-intent salvage surgery in this patient population. Materials and methods: Details of patients undergoing salvage surgery for locoregional failure after CRT and durvalumab were identified from an institutional surgical database. Each patient's case underwent multidisciplinary discussion at initial disease presentation, and again at time of progression. Results: Ten patients underwent salvage surgery for LRF after prior concurrent (n = 9) or sequential (n = 1) platinum-based high-dose chemo-radiotherapy followed by durvalumab. Consolidation durvalumab was completed in 4 patients, and discontinued in 6, due to either toxicity or disease progression. Median time between end of radiotherapy to detection of LRF was 19 months (range 6-75). Seven patients underwent a lobectomy, 1 a bilobectomy and 2 patients a pneumonectomy. Postoperative morbidity (Clavien-Dindo grade III-V) and 90-day mortality were 10% and 0%, respectively. Median follow-up after surgery was 7 months (range 1-25) during which 2 patients died (both 9 months post-operatively), one due to distant progression, and one of sepsis/ bleeding. Eight patients are alive at 1-23 months post-surgery, with 6 showing no evidence of disease. Conclusions: Our results suggest that salvage pulmonary resection can be performed safely in selected patients with LRF following chemoradiotherapy and durvalumab. This radical-intent treatment option merits consideration by multidisciplinary lung tumor boards.Thoracic Surger

Completeness of lymph node dissection in patients undergoing minimally invasive- or open surgery for non-small cell lung cancer: A nationwide study

Objective: In patients with NSCLC, lymph node metastases are an important prognostic factor. Despite an accurate pre-operative work up, for optimal staging an intrapulmonary-and mediastinal lymph node dissection (LND) as part of the operation is mandatory. The aim of this study is to assess the completeness of LND in patients undergoing an intended curative resection for NSCLC in the Netherlands and to compare performance between open surgery and minimally invasive surgery (MIS).Materials and methods: The intraoperative LND was evaluated in 7460 patients who had undergone a lobectomy for clinically staged N0-1 NSCLC (2013-2018). The LND was considered complete, when three mediastinal (N2) lymph node stations, including station 7, were sampled or dissected, in addition to the lymph nodes from station 10 and 11. A comparison was made between open surgery and MIS.Results: Of 5154 patients, who had MIS, a sufficient intrapulmonary LND was performed in 47.9% and a sufficient mediastinal LND in 58.6%. A complete LND was performed in 31.6%. For 2306 patients who had an open resection, these numbers were 45.0%, 59.0%, and 30.6%, respectively. The overall between hospital variation in a complete LND ranged between 0 and 72.5%.Conclusion: In the Netherlands, a complete LND of both intrapulmonary-and mediastinal lymph nodes is performed only in a minority of patients with clinically staged N0-1 NSCLC, with substantial between hospital variation. No differences were seen between open surgery and MIS. Because of poor performance, completeness of lymph node dissection will be recorded as a mandatory performance indicator in our national audit, to improve the quality of resection.(c) 2020 Elsevier Ltd, BASO The Association for Cancer Surgery, and the European Society of Surgical Oncology.
