Mediastinoscopy

Mediastinoscopy is a minimally invasive surgical procedure used to examine and biopsy the mediastinal lymph nodes.
It is commonly employed in the diagnosis and staging of lung cancer, as well as the evaluation of other thoracic conditions.
The procedure involves making a small incision in the neck and inserting a thin, lighted instrument called a mediastinoscope into the chest to visualize the mediastinal structures.
Mediastinoscopy allows for the collection of tissue samples for pathological analysis, aiding in the accurate diagnosis and treatment planning.
This important diagnostic tool helps healthcare providers make informed decisions about the most appropriate course of management for their patients.

This single-group study was developed by the authors and conducted at two medical centers in the United States. The patients received two doses of intravenous nivolumab (at a dose of 3 mg per kilogram of body weight) every 2 weeks. It was planned that surgery would be performed approximately 4 weeks after the first dose. All the patients provided written informed consent.
The primary end points were safety and feasibility. The key secondary and exploratory end points were radiologic and pathological responses to treatment and immunologic, genomic, and pathological correlates of response in blood and tumor (Fig. S1 in Supplementary Appendix 1, available with the full text of this article at NEJM.org).
All the patients were monitored for adverse events, according to the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0.12 Feasibility was prospectively defined as any delay in the planned surgery of no more than 37 days (i.e., a surgical delay of >30 days and 7 days for scheduling). In a safety run-in phase, an initial 6 patients were followed for perioperative adverse events of grade 3 or 4 for 90 days after the administration of the last nivolumab dose (or day 30 after surgery). With the goal of exploring the antitumor immune response in depth, the study then expanded to enroll a total of 20 patients who underwent complete tumor resection.
All the patients underwent baseline tumor staging, including pretreatment biopsy, pathological evaluation of mediastinal lymph nodes (if indicated) by means of bronchoscopy or mediastinoscopy, positron-emission tomography–computed tomography (PET–CT), and contrast-enhanced CT or magnetic resonance imaging of brain and chest; chest CT was repeated within 7 days before surgery. Changes in tumor size were evaluated according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1.13 (link) Resection of the primary tumor and lymph nodes was completed according to institutional standards. All the patients were offered conventional adjuvant chemotherapy or radiotherapy, if such therapy was clinically indicated, and were followed for recurrence-free and overall survival.

In this Institutional Review Board approved retrospective study, patients aged ≥70 years, who received surgery or SBRT for T1–2 N0 M0 clinically confirmed lung cancer from January 2012 to December 2017 were eligible for inclusion. Clinically confirmed lung carcinoma was defined as a primary suspicious mass, part-solid, or ground-glass opacity nodule with spiculated or smooth margins on CT images, that persisted for ≥3 months and showed an increase in its longest axis. Patients with radiologically suspicious lymph nodes underwent endobronchial ultrasonography or mediastinoscopy. In addition, all patients underwent bone imaging and brain magnetic resonance imaging. Positron emission-computed tomography (PET/CT) was necessary for diagnosis in cases in whom biopsy was not considered medically safe or the patient refused to undergo biopsy, and recommended for all patients. Disease staging was performed using the Union for International Cancer Control TNM Classification of Malignant Tumors, 7th edition. The multidisciplinary team (i.e., surgeons, radiation oncologists, and diagnostic radiologists) examined and discussed the SBRT indications prior to the initiation of treatment. All multidisciplinary consultations were recorded in detail.
Patients with adequate pulmonary function and absence of other contraindicating medical comorbidities – according to the thoracic surgeon – were selected for surgery resection. The performance of a lobectomy, sub-lobectomy, thoracotomy, or video-assisted thoracic surgery (VATS) was discussed among the multidisciplinary team prior to the procedure. Radical lymph node dissection was performed in accordance with the current guidelines [15 (link)].
Inoperable patients – according to the thoracic surgeon – and those who refused surgical resection were selected for SBRT. The whole process of SBRT has been described previously in detail in our previous study [16 (link), 17 (link)]. The gross tumor volume (GTV) included only the primary tumor; the internal target volume (ITV) was determined using CT with a four-dimension CT technique, and the tumor motion was assessed. The planning target volume (PTV) was defined as the ITV expanded by a 5-mm margin in each direction. The dose of SBRT was prescribed to the highest isodose line, which needed to cover 100% of the ITV and > 95% of the PTV. The treatment plans were optimized to limit the administration of high doses to regions of organs at risk. Twenty (20%) SBRT patients received more conservative fractionation schedules with a lower dose per fraction but more fractions, due to larger tumors or those adjacent to critical organs. The biological effective dose (BED) was calculated using BEDα/β = nd (1+ d/α/β), where n = number of fractions, d = dose per fraction, and α/β = 10 for the tumor in line with prior studies.

Patients with radiological N0 disease without distant metastasis either underwent pre-operative EBUS-TBNA or directly proceeded to surgical resection at the discretion of attending physicians, since there was no consistent indication for pre-operative EBUS-TBNA in patients with radiological N0 disease. EBUS-TBNA was performed with a convex probe EBUS bronchoscope (BF-UC260F-OL8; Olympus, Tokyo, Japan) and a 22-gauge needle (NA-201SX-4022; Olympus) under moderate sedation with intravenous midazolam and fentanyl. After systematic inspection of lymph node stations, each visible lymph node was sampled in the standard N3 to N2 to N1 fashion, with size cut-offs of ≥5 mm in the short axis by EBUS. We conducted three passes per node and at least two passes when core tissue was obtained [17 (link), 18 (link)]. Transoesophageal bronchoscopic ultrasound-guided fine-needle aspiration (EUS-FNA-B) using the EBUS bronchoscope was done in selected cases [19 (link)]. Rapid on-site cytopathological evaluation was not available. When the clinical suspicion of mediastinal metastasis remained high despite a negative result in EBUS-TBNA, pre-operative mediastinoscopy was performed. Otherwise, surgical resection with MLND was considered if there was no metastasis to mediastinal lymph nodes in EBUS-TBNA.
The surgical procedures included resection of the affected lung plus lymph node dissection of the ipsilateral hilum and mediastinum, including all visible and palpable lymph nodes irrespective of size [20 (link), 21 (link)]. MLND consisted of en bloc resections of all nodes at stations 10R, 9, 8, 7, 4R, 3 and 2R for right-sided tumours and nodes at stations 10L, 9, 8, 7, 6, 5 and 4L for left-sided tumours.

The following data were recorded during the preoperative examination: Sex, age, height, body weight, BMI, smoking history, complete blood count (leukocytes, hemoglobin, platelets), liver function tests (liver enzymes, albumin), renal function tests, preoperative oxygen saturation, history of previous surgery, and concomitant diseases (type 2 diabetes, hypertension, pulmonary and cardiac diseases).
The following data were also collected: History and physical examination findings, chest radiographs, computed tomographic examinations of the chest (CT), electrocardiography (ECG) and echocardiography (if required), pulmonary function test results (forced expiratory volume (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio), and arterial blood gases. In patients with lung cancer, the type and stage of malignancy were determined, and flexible bronchoscopy was performed.
During the intraoperative process, the type of endotracheal tube, the duration of anesthesia and surgery, the surgical procedure (VATS, thoracotomy, mediastinoscopy, and others) performed, and complications that required intraoperative treatment were also noted.
PPCs have been defined as complications that occur in the postoperative period and cause clinical conditions.

All patients underwent baseline tumor staging, including contrast-enhanced computed tomography (CT) of brain, chest and abdomen, positron-emission tomography-CT (PET-CT), and pathological evaluation of any enlarged mediastinal lymph nodes by means of bronchoscopy and/or mediastinoscopy. Classification of NSCLC was based on the 8th edition of TNM by the International Association for the Study of Lung Cancer (12 (link)). All cases were discussed in multidisciplinary meetings. Decision to initiate systemic treatment was based on advanced unresectable clinical stage IIIB to IVB disease, with treatment protocols varying according to the oncologic center as well as the use of durvalumab “off label”. Introduction of ICI was either at first, second or third line of treatment, depending upon the oncologic center protocols. Radical management of metastases were as followed. Persistent adrenal gland metastases were treated by surgical resection or radiotherapy. Liver metastases and distant lymph nodes metastases disappeared under immunotherapy. Brain and bone metastases were treated by radiotherapy. All patients underwent a complete reassessment of the tumor with CT and PET-CT within 6 weeks before surgery. Upon reassessment, eligibility to surgical resection was suggested in case of well controlled patient and an operable patient. Patients were defined as “well controlled” on the following criteria:
Once the patients were defined as well controlled, selection for surgical resection was based on:

Before surgery, all cases were individually discussed in a multidisciplinary tumour board. Preoperative assessment included a chest CT and fluorodeoxyglucose-positron emission tomography scan with maximum standard uptake values and a transthoracic or bronchoscopic biopsy of the lesion to determine the histology when technically feasible. In case of suspected lymph node involvement on preoperative imaging, an endobronchial ultrasound fine-needle aspiration or mediastinoscopy was performed before surgery. The choice of treatment modality (lobectomy versus segmentectomy) was driven by unmeasured patient characteristics, but we usually favoured a segmentectomy in case of smaller, peripherally located lesions in a specific segment with an achievable surgical margin of ≥2 cm.
Patients were operated under general anaesthesia with single lung ventilation by double lumen intubation. A standardized 3-port anterior approach (utility incision in the 4th intercostal space, 1 incision for the 10 mm 30° thoracoscope in the 7th intercostal space anteriorly and a 3rd incision posteriorly) or 1-port approach (since 2018) were used. Segmentectomy procedures were performed with individual dissection of the segmental bronchus, arteries and veins followed by a systematic hilar and mediastinal lymph node resection. Intersegmental plane was identified using systemic injection of indocyanine green when necessary and the dissection itself was performed by using stapling or energy device. Surgical margins were systematically evaluated and all types of segmentectomies were performed. In case of suspected hilar nodal involvement, a frozen section was performed and a completion lobectomy was undertaken if the nodal status was upstaged (N1). Surgical specimens were extracted through a protective bag.
All cases were discussed again after surgery in a multidisciplinary tumour board to assess the need of adjuvant chemotherapy. The follow-up consisted in chest CT scans every 3 months for the 1st 2 years, then every 6 months for a total of 5 years.
