Randomized Controlled Trial
PURPOSE
Resectable non-small-cell lung cancer (NSCLC) with a high probability of mediastinal nodal involvement requires mediastinal staging by endosonography and, in the absence of nodal metastases, confirmatory mediastinoscopy according to current guidelines. However, randomized data regarding immediate lung tumor resection after systematic endosonography versus additional confirmatory mediastinoscopy before resection are lacking.
METHODS
Patients with (suspected) resectable NSCLC and an indication for mediastinal staging after negative systematic endosonography were randomly assigned to immediate lung tumor resection or confirmatory mediastinoscopy followed by tumor resection. The primary outcome in this noninferiority trial (noninferiority margin of 8% that previously showed to not compromise survival, < .0250) was the presence of unforeseen N2 disease after tumor resection with lymph node dissection. Secondary outcomes were 30-day major morbidity and mortality.
RESULTS
Between July 17, 2017, and October 5, 2020, 360 patients were randomly assigned, 178 to immediate lung tumor resection (seven dropouts) and 182 to confirmatory mediastinoscopy first (seven dropouts before and six after mediastinoscopy). Mediastinoscopy detected metastases in 8.0% (14/175; 95% CI, 4.8 to 13.0) of patients. Unforeseen N2 rate after immediate resection (8.8%) was noninferior compared with mediastinoscopy first (7.7%) in both intention-to-treat (Δ, 1.03%; UL 95% CIΔ, 7.2%; = .0144) and per-protocol analyses (Δ, 0.83%; UL 95% CIΔ, 7.3%; = .0157). Major morbidity and 30-day mortality was 12.9% after immediate resection versus 15.4% after mediastinoscopy first ( = .4940).
CONCLUSION
On the basis of our chosen noninferiority margin in the rate of unforeseen N2, confirmatory mediastinoscopy after negative systematic endosonography can be omitted in patients with resectable NSCLC and an indication for mediastinal staging.

BACKGROUND
Pulmonary complications after thoracic surgery are common and are associated with prolonged hospital stay, higher costs, and increased mortality. This study aimed to evaluate the value of The Assess Respiratory risk in Surgical Patients in Catalonia (ARISCAT) risk index in predicting pulmonary complications after thoracic surgery.
METHODS
This retrospective study was conducted at Almoosa Specialist Hospital, Saudi Arabia, from August 2016 to August 2019 and included 108 patients who underwent thoracic surgery during the study period. Demographic data, ARISCAT risk index score, length of hospital stay, time of chest tube removal, postoperative complications, and time of discharge were recorded.
RESULTS
The study involved 108 patients who met the inclusion criteria. Their mean age was 42.5 ± 18.9 years, and most of them were men (67.6%). Comorbid diseases were present in 53.7%, including mainly type 2 diabetes mellitus and hypertension. FEV1% was measured in 58 patients, with a mean of 71.1 ± 7.3%. The mean ARISCAT score was 39.3 ± 12.4 and ranged from 24 to 76, with more than one-third (35.2%) having a high score grade. The most common surgical procedures were thoracotomy in 47.2%, video-assisted thoracoscopic surgery (VATS) in 28.7%, and mediastinoscopy in 17.6%. Postoperative pulmonary complications (PPCs) occurred in 22 patients (20.4%), mainly pneumonia and atelectasis (9.2%). PPCs occurred most frequently during thoracotomy (68.2%), followed by VATS (13.6%), and mediastinoscopy (9.1%). Multinomial logistic regression of significant risk factors showed that lower FEV1% (OR = 0.88 [0.79-0.98]; p=0.017), longer ICU length of stay (OR = 1.53 [1.04-2.25]; p=0.033), a higher ARISCAT score (OR = 1.22 [1.02-1.47]; p=0.040), and a high ARISCAT grade (OR = 2.77 [1.06-7.21]; p=0.037) were significant predictors of the occurrence of postoperative complications.
CONCLUSION
ARISCAT scoring system, lower FEV1% score, and longer ICU stay were significant predictors of postoperative complications. In addition, thoracotomy was also found to be associated with PPCs.

Review
OBJECTIVE
To compare the clinicopathological features and perioperative outcomes of video-assisted mediastinoscopy esophagectomy (VAME) compared to video-assisted thoracoscopy esophagectomy (VATE) in esophageal cancer.
METHODS
We comprehensively searched online databases (PubMed, Embase, Web of Science and Wiley online library) to find available studies exploring the clinicopathological features and perioperative outcomes between VAME and VATE in esophageal cancer. Relative risk (RR) with 95% confidence interval (CI) and standardized mean difference (SMD) with 95% CI were used to evaluate the perioperative outcomes and clinicopathological features.
RESULTS
A total of seven observational studies and one randomized controlled trial involving 733 patients were considered eligible for this meta-analysis, of which 350 patients underwent VAME in contrast to 383 patients underwent VATE. Patients in the VAME group had more pulmonary comorbidities (RR = 2.18, 95% CI 1.37-3.46, = 0.001). The pooled results showed that VAME shortened the operation time (SMD = -1.53, 95% CI -2.308--0.76, = 0.000), and retrieved less total lymph nodes (SMD = -0.70, 95% CI -0.90--0.50, = 0.000). No differences were observed in other clinicopathological features, postoperative complications or mortality.
CONCLUSIONS
This meta-analysis revealed that patients in the VAME group had more pulmonary disease before surgery. The VAME approach significantly shortened the operation time and retrieved less total lymph nodes and did not increase intra- or postoperative complications.

Northeast India, a region of geographic, cultural, and ethnic diversity comprises of Assam, Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Tripura, and Sikkim. Geographically, two-thirds of the area is hilly terrain. The North Eastern Region (NER) shows marked diversity in customs, cultures, cuisines, traditions, and languages. The Aizawl district of Mizoram (269.4) and the Papumpare district of Arunachal Pradesh (219.8) have the highest age-adjusted incidence rates (AAR) of cancer among males and females, respectively. Meghalaya has the highest relative proportion of cancers associated with tobacco use, with 70.4% in men and 46.5% in women. This correlates with the high prevalence of tobacco use. The Dr Bhubaneswar Borooah Cancer Institute, Guwahati, was inaugurated in 1973. The Institute currently conducts M.Ch. Surgical Oncology, Head and Neck Oncology and Gynaecologic Oncology, and DM courses in Medical Oncology and Onco-pathology. The year 2019 saw the creation of a high-dose radioisotope therapy ward. Allogenic Bone Marrow Transplantation (BMT) was started in 2021-2022. State Cancer Institute (SCI), Guwahati, houses a medical cyclotron, which is the only one in Northeast India. Assam Cancer Care Foundation (ACCF) is a joint venture between the Government of Assam and the Tata Trusts, with a three-level cancer grid. The Cachar Cancer Hospital and Research Centre (CCHRC) offers holistic, subsidised cancer care to over 4000 new patients every year. North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences (NEIGRIHMS) offers endobronchial ultrasound (EBUS) and mediastinoscopy services, enabling accurate staging of lung cancers. While the cancer care facilities in NER have grown over the years, it is not commensurate with the high incidence of cancers in the region.

OBJECTIVE
To compare the short-term outcomes and postoperative quality of life in patients with esophageal cancer between inflatable videoasisted mediastinoscopic transhiatal esophagectomy (IVMTE) and minimally invasive Mckeown esophagectomy (MIME), and to evaluate the value of IVMTE in the surgical treatment of esophageal cancer.
METHODS
A prospective, nonrandomized study was adopted. A total of 60 esophageal cancer patients after IVMTE and MIME December 2019 to January 2022 were included. Among them, 30 patients underwent IVMTE and 30 patients underwent MIME. Shortterm outcomes (including the operation time, intraoperative blood loss, postoperative drainage 3 days, total postoperative tube time, postoperative hospital stay, number and number of thoracic lymph node dissection stations, postoperative complications and so on), postoperative quality of life, [including Quality of Life Core Questionnaire (QLQ-C30) and the esophageal site-specific module (QLQ-OES18)] were compared between the 2 groups.
RESULTS
The operation time, intraoperative blood loss, postoperative drainage volume and total postoperative intubation time in IVMTE group were significantly lower than those in MIME group ( < 0.05). A total of 22 patients had postoperative complications, including 7 patients in IVMTE group (23.3%) and 15 patients in MIME group (50.0%). There was significant difference between the two groups ( = 0.032). The physical function, role function, cognitive function, emotional function and social function and the overall health status in the IVMTE group were higher than those in the MIME group at all time points after operation, while the areas of fatigue, nausea, vomiting and pain symptoms in the MIME group were lower than those in the MIME group at all time points after operation.
CONCLUSION
IVMTE is a feasible and safe alternative to MIME. Therefore, when the case is appropriate, IVMTE should be given priority, which is conducive to postoperative recovery and improve the quality of life of patients after operation.

Anthracosis is an environmental lung disease caused by carbon deposition and pigmentation in the airways. However, in rare instances, it can also have systemic involvement. We present a patient with B-symptoms and diffuse lymphadenopathy who was diagnosed with the infrequently described nodal anthracosis. A 64-year-old Vietnamese gentleman with a 50-pack-year smoking history who was recently diagnosed with prostate cancer post-radical prostatectomy and awaiting radiation therapy presented with generalized weakness, low-grade fever, night sweats, and unquantifiable weight loss for a month. He was hemodynamically stable, and examination revealed bilateral inguinal and axillary lymphadenopathy. Computed tomography (CT) showed diffuse lymphadenopathy involving the mediastinum, hilar, axillary, mesenteric, retroperitoneal, and bilateral iliac chains with multiple diffuse pulmonary nodules. Laboratories disclosed anemia, thrombocytopenia, elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), albumin-globulin (A-G) reversal, and sterile blood cultures. The disseminated intravascular coagulation panel was negative with normal fibrinogen and mildly elevated D-dimer. Autoimmune workup, including antinuclear antibody (ANA), was negative. Infectious workup included , , , Lyme serology, QuantiFERON-TB Gold, HIV, and hepatitis panel, and all were negative. He was managed with broad-spectrum antibiotics, which were discontinued after a negative infectious workup. He also complained of a new-onset holocranial headache with no features of meningitis; an MRI with contrast revealed focal occipital leptomeningeal involvement and cerebral edema with occipital lymphadenopathy. A lumbar puncture was planned but deferred at the patient's request. An excisional lymph node biopsy of the left axillary lymph node revealed reactive follicular hyperplasia with no evidence of malignancy, with flow cytometry negative for any evidence of B- or T-cell malignancies. He continued to have persistent low-grade fevers. A bone marrow biopsy showed 70% cellularity with paratrabecular interstitial lymphoid aggregates composed of both T and B cells, which was nonspecific, and flow cytometry could not be done due to dry tap. An F-18-fluorodeoxyglucose positron emission tomography (FDG PET) scan showed extensive hypermetabolic disease both above and below the diaphragm with bulky mediastinal adenopathy and splenomegaly. Subsequently, he underwent a mediastinoscopy and biopsy of the mediastinal lymph nodes, which demonstrated reactive hyperplasia and abundant anthracitic pigment on microscopic examination, consistent with the diagnosis of nodal anthracosis. He was managed conservatively, discharged, and found to have spontaneously resolved symptoms at a six-week follow-up. Nodal anthracosis with PET-positive mediastinal and hilar lymphadenopathy is a rare presentation of anthracosis that mimics infectious conditions, granulomatous diseases, and malignancies. The pigment deposition can cause persistent inflammatory activity and should be considered an infrequent but important explanation of lymphadenopathy in patients without known biomass exposure.

BACKGROUND
Since its introduction in 1959 by Carlens (1), Mediastinoscopy has been, for long, used for assessment of the mediastinum (superior and middle) for establishing a histological diagnosis of mediastinal masses of undefined cause, and for Lung carcinomas staging. The use of Mediastinoscopy has been decreasing lately due to the introduction of other less invasive techniques (e.g., endoscopic ultrasound-directed fine needle aspiration cytology), however, it is still a cheap and effective tool that can be utilized in underprivileged centers.
OBJECTIVE
To emphasize how does Mediastinoscopy plays an important role in confirming the clinical diagnosis of isolated mediastinal lymphadenopathy and reviewing its utility.
METHODS
These are a retrospective analysis of medical charts for patients who underwent diagnostic cervical mediastinoscopy during (2012 - 2018) at a University hospital in Saudi Arabia. The included patients are presented with an isolated mediastinal lymph node enlargement, in the absence of underlying cause and was found to be significant (>1cm in its short axis) by computed tomography. The patient who had a known cause (e.g., Sarcoidosis) or were diagnosed via other tools, was excluded.
RESULTS
Mediastinoscopy was performed on 56 patients, 38 of them were males (68%) and 18 females (32%), with a mean age of (37.5 ± 10 years). The patients' most common presenting symptoms were persistent cough (49%), fever of unknown origin (38%) and weight loss (36%) with an average of 2 symptoms per patient, while in 4 patients (7%) lymphadenopathy was discovered incidentally during the CT scan for other reasons. In addition, the histopathological examination of specimens obtained confirmed the most common diagnoses, Sarcoidosis in 17 patients (30%), lymphoma in 12 patients (21%) and TB in 10 patients (18%). The mean hospital stay (calculated from the day of the procedure) was (2.5 ± 4 days) including work up, with only one mortality (2%) and 3 patients (5%) had experienced post-operative complications.
CONCLUSION
The diagnostic Mediastinoscopy is both safe and efficient in the diagnosis of patients with isolated mediastinal lymphadenopathy, requiring a minimal surgical setup and is considered cost-effective. Therefore, it is a valid choice of investigating such cases in other underprivileged centers, as it reaches a tissue-based diagnosis, while other techniques are used for staging purposes.
