Wedge resection, segmentectomy, and lobectomy: oncologic outcomes based on extent of surgical resection for ≤2 cm stage IA non-small cell lung cancer.

Background: Long-standing controversy has existed over whether sublobar resection is an adequate oncological procedure for clinical stage IA non-small cell lung cancer (NSCLC) ≤2 cm, despite the recent randomized trial reports of Japanese Clinical Oncology Group (JCOG) 0802 and Cancer and Leukemia Group B (CALGB) 140503 demonstrating non-inferior outcomes with sublobar resection compared to lobectomy. As practice patterns shift, we sought to compare oncologic outcomes in patients with these early-stage tumors after wedge resection, segmentectomy, or lobectomy in a contemporary, real-world, cohort. Methods: A retrospective review of a prospectively maintained database from a single institution was conducted from 2011 to 2020 to identify all patients with clinically staged IA1 or IA2 NSCLC (tumors ≤2 cm with no nodal involvement). The primary outcomes of interest were overall survival (OS) and disease-free survival (DFS), with secondary outcomes of lung cancer-specific survival (LCSS), recurrence patterns, and perioperative morbidity and mortality. Results: A total of 480 patients were identified; 93 (19.4%) patients underwent wedge resection, 90 (18.7%) received segmentectomy, and 297 (61.9%) underwent lobectomy. Patients who underwent wedge resection had worse Eastern Cooperative Oncology Group (ECOG) performance status (23.7% ECOG 1 or 2 vs. 5.6% among segmentectomy and 5.4% among lobectomy, P<0.05). Both wedge resection and segmentectomy patients had lower preoperative mean percentage of predicted forced expiratory volume in one second (%FEV1) compared to the lobectomy group (81.8% and 82.6% vs. 89.6%, P=0.002), a higher proportion of patients with chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD), and a higher Charlson Comorbidity Index. There were no statistically significant differences in 5-year OS, DFS, or LCSS between groups: 90%, 61%, 78% for wedge resections compared with 85%, 75%, 86% for segmentectomy, and 87%, 77%, 87% for lobectomy, respectively. Recurrence was observed in 17 patients who underwent wedge resection (18.3%, 8 local, 9 distant), 12 patients who received segmentectomy (13.4%, 6 local, 6 distant), and 38 patients who underwent lobectomy (12.8%, 11 local, 27 distant), which was not significantly different (P=0.36). Conclusions: Patients with inferior performance status or lower baseline pulmonary function are more likely to receive wedge resection for clinical stage IA NSCLC ≤2 cm in size. For these small tumors, lobectomy, segmentectomy, and wedge resection provide comparable oncologic outcomes.

Preventing Bacterial Contamination of Breast Implants Using Infection Mitigation Techniques: An In Vitro Study.

BACKGROUND: Bacterial contamination of implants has been linked to biofilm formation and subsequent infection, capsular contracture, and breast implant-associated anaplastic large cell lymphoma. Reducing contamination during implant insertion should therefore reduce biofilm formation disease sequelae. OBJECTIVES: The aim of this study was to compare levels of contamination between preventative techniques. METHODS: A model to simulate the passage of implants through a skin incision was designed that utilized a sterile textured polyvinyl plastic sheet contaminated with Staphylococcus epidermidis. In the first stage of the polyvinyl contamination model, implants were subject to infection-mitigation techniques and passed through the incision, then placed onto horse blood agar plates and incubated for 24 hours. In the second stage of the study the same contamination was applied to human abdominal wall specimens. A 5 cm incision was made through skin and fat, then implants were passed through and levels of contamination were measured as described. RESULTS: Smooth implants grew a mean of 95 colony-forming units (CFUs; approximately 1 CFU/cm2) and textured implants grew 86 CFUs (also approximately 1 CFU/cm2). CFU counts were analyzed by the Mann-Whitney U-test which showed no significant difference between implant types (P < .05); independent-sample t-tests showed a significant difference. The dependent-variable techniques were then compared as groups by one-way analysis of variance, which also showed a significant reduction compared with the control group (P < .01). CONCLUSIONS: This in vitro study has shown the effectiveness of antiseptic rinse and skin/implant barrier techniques for reducing bacterial contamination of breast implants at the time of insertion.

Autologous Fat Grafting in Breast Augmentation: A Systematic Review Highlighting the Need for Clinical Caution.

BACKGROUND: Autologous fat grafting (AFG) is a breast augmentation method for treating volume and contour abnormalities. This systematic review aims to summarize complications, radiologic safety, volume retention, and patient satisfaction associated with AFG. METHODS: The PubMed, Embase, Google Scholar, Cochrane Central Register of Controlled Trials, Wiley library, clinical key/Elsevier, and EBSCO databases were searched for relevant studies from January of 2009 to March of 2022. Articles describing AFG for breast augmentation were selected based on predetermined inclusion and exclusion criteria. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were adhered to, and the study was registered on the International Prospective Register of Systematic Reviews. The Risk of Bias in Nonrandomized Studies of Interventions assessment was used to assess the quality of studies and the risk of bias was measured using the Cochrane Risk of Bias Assessment Tool for Nonrandomized Studies of Interventions. RESULTS: A total of 35 studies comprising 3757 women were included. The average follow-up duration was 24.5 months (range, 1 to 372 months). The overall complication rate was 27.8%, with fat necrosis making up 43.7% of all complications. Average fat volume injected was 300 mL (range, 134 to 610 mL), and average volume retention was 58% (range, 44% to 83%). Volume retention was greater with supplementation of fat with platelet-rich plasma and stromal vascular fraction. The most common radiologic changes were fat necrosis (9.4%) and calcification (1.2%). After 1 year of follow-up, patient satisfaction was, on average, 92% (range, 83.2% to 97.5%). The included studies were of good quality and consisted of a moderate risk of bias. CONCLUSIONS: AFG was associated with an overall complication rate of 27.8%. Additional supplementation of fat with platelet-rich plasma and stromal vascular fraction may improve graft survival. Despite poor volume retention being a persistent drawback, patient satisfaction remains high.

Should sampling of three N2 stations be a quality metric for curative resection of stage I lung cancer?

OBJECTIVE: In 2022, the American College of Surgeons Commission on Cancer issued standard 5.8 quality metric for curative lung cancer resections requiring nodal resection from 3 N2 stations. In this report, we compare oncologic outcomes after resection of 3 N2 stations versus 2 N2 stations in stage I non-small cell lung cancer. METHODS: A retrospective review from a single institution database was conducted from 2011 to 2020 to identify patients with clinical stage I non-small cell lung cancer. Patients with a history of lung cancer, carcinoid tumors, and ground-glass lesions less than 50% solid component were excluded. The primary outcome was overall survival. Secondary outcomes included disease-free survival, recurrence patterns, and nodal upstaging. RESULTS: A total of 581 patients were identified and divided into 2 groups based on the number of N2 stations examined: Group A had 2 N2 stations examined (364 patients), and group B had 3 or more N2 stations examined (217 patients). Baseline demographic and clinical characteristics were similar between groups. In group A, N1 and N2 positive nodal stations were present in 8.2% (30/364) and 5.2% (19/364) of patients versus 7.4% (16/217) and 5.5% (12/217), respectively, in group B. Five-year overall survival and disease-free survival were 89% and 74% in group A versus 88% and 78% in group B, respectively. Recurrence occurred in 56 patients (15.4%) in group A (6.6% local and 8.8% distant) and 29 patients (13.4%) in group B (5.1% local and 8.3% distant; P = .73). CONCLUSIONS: There was no significant difference in oncological outcomes in stage I non-small cell lung cancer resections that included 2 N2 stations compared with at least 3 N2 stations examined.

Unicentric Castleman's disease imitating metastatic melanoma: A case report.

INTRODUCTION AND IMPORTANCE: This case report shows a unique case of Castleman's disease in the context of histopathological diagnosis of cutaneous melanoma where clinical and radiological features of Castleman's disease were masked by presumptive diagnosis of metastatic melanoma. The disease is part of a group of lymphoproliferative disorders with characteristic histopathological features that can occur in any lymph node in the body, characterised by slow growing painless masses which are asymptomatic until mass effect occurs. This case highlights the need for caution when considering management of lymphadenopathy with clinically/radiologically suspicious nodes. PRESENTATION OF CASE: A 65 year old man with metastatic melanoma of the left elbow presented for axillary sentinel node mapping and was found to have a hypoechoic enlarged node on ultrasound. This was further investigated and found to be a lymphoproliferative growth pathognomonic for Castlemans disease. DISCUSSION: Whilst clinically detected lymphadenopathy in the draining node basin of a primary cutaneous melanoma is highly suspicious for nodal metastasis, it is sometimes not possible to confirm or exclude this diagnosis without complete histological examination of the node. Multidisciplinary input from the surgeon, histopathologist and radiologist is a key step in confirming diagnosis. CONCLUSION: Alternative diagnoses must be considered in the context of lymphadenopathy, even in the context of malignant melanoma.

Surgical Treatment at an Academic Medical Center is Associated with Statistically Insignificant Lung Cancer Survival Outcome Differences Related to ZIP Code.

BACKGROUND: Low socioeconomic status is a well-characterized adverse prognostic factor in large lung cancer databases. However, such characterizations may be confounded as patients of lower socioeconomic status are more often treated at low-volume, non-academic centers. We evaluated whether socioeconomic status, as defined by ZIP code median income, was associated with differences in lung cancer resection outcomes within a high-volume academic medical center. METHODS: Consecutive patients undergoing resection for non-small cell lung cancer were identified from a prospectively maintained database (2011-18). Patients were assigned an income value based on the median income of their ZIP code as determined by census-based geographic data. We stratified the population into income quintiles representative of SES and compared demographics (chi-square), surgical outcomes, and survival (Kaplan-Meier). RESULTS: We identified 1,693 patients, representing 516 ZIP codes. Income quintiles were Q1: $24,421-53,151; Q2:$53,152-73,982; Q3:$73,983-99,063; Q4:$99,064-123,842; and Q5:$123,843-250,001. Compared to Q5 patients, Q1 patients were younger (median 69 vs. 73, p < 0.001), more likely male (44 vs. 36%, p = 0.035), and more likely Asian, Black, or self-identified as other than white, Asian, or Black. (67 vs. 11%, p = < 0.001). We found minor differences in surgical outcomes and no significant difference in 5-year survival between Q1 and Q5 patients (5-year: 86 vs. 85%, p = 0.886). CONCLUSIONS: Surgical care patterns at a high-volume academic medical center are similar among patients from varying ZIP codes. Surgical treatment at such a center is associated with no survival differences based upon socioeconomic status as determined by ZIP code. Centralization of lung cancer surgical care to high-volume centers may reduce socioeconomic outcome disparities.

Video- and Robotic-Assisted Thoracoscopic Truncal Vagotomy.

A subset of patients with marginal ulcers after Roux-en-Y gastric bypass (RNYGB) is refractory to medical management. Here we report a retrospective review of a single institution cohort (N = 10) of video- or robotic-assisted thoracoscopic (VATS or RATS) truncal vagotomies performed between 2013 and 2018. All patients had recurrent marginal ulcers following RNYGB complicated by bleeding or perforation, refractory to medical management for a median of 3.5 months prior to undergoing truncal vagotomy. With a median of 23 months' follow-up, only three patients had continued symptoms (70% symptom resolution) post-operatively. Only one patient who had repeat endoscopy after the procedure had documented endoscopic evidence of recurrent marginal ulcer (83% endoscopic resolution). VATS or RATS truncal vagotomy is a safe and effective method to treat complicated marginal ulceration after RNYGB. After an average duration of unsuccessful medical treatment lasting three months, vagotomy led to successful resolution in 70-83% of patients.

Prospective Study of Clinical Outcomes From a Breast Implant Assessment Service.

BACKGROUND: Breast augmentation remains the commonest cosmetic surgical procedure worldwide, in spite of recent regulatory action. OBJECTIVES: The aim of this study was to evaluate women with breast implants attending a breast implant assessment clinic and to capture clinical and implant data in women presenting to the service. METHODS: Patients were enrolled prospectively between January 2018 and December 2021. Clinical, implant, and practitioner data were recorded. Patients reported satisfaction on size, shape, and overall outcome as well as the presence or pain. Radiological evaluation, where indicated, was performed and data were included on these findings. RESULTS: A total of 603 patients were assessed. Their mean age was 42.7 years and mean age at implantation was 29.1 years. The most common complications were capsular contracture followed by pain, waterfall deformity, and double bubble, with rupture/contracture rates increasing after the 10-year mark. The risk of double bubble was significantly lower if patients were operated on by certified practitioners (odds ratio = 0.49, P = 0.011). There was almost universally poor awareness of the risks of breast implants in patients presenting for evaluation. CONCLUSIONS: This study has shown benefit in a breast implant assessment clinic to gather information on adverse events and patient-reported outcomes following breast implant surgery. Having appropriately trained and certified practitioners perform cosmetic augmentation significantly lowers the risk of implant malposition and deformity. Any adverse event occurring within 5 years of initial surgery should be flagged as a mandatory reportable clinical indicator and trigger further investigation.

Surgical resection after neoadjuvant durvalumab and radiation is feasible and safe in non-small cell lung cancer: Results from a randomized trial.

OBJECTIVE: Several trials have recently reported the safety of pulmonary resection after neoadjuvant immunotherapy with encouraging major pathological response rates. We report the detailed adverse events profile from a recently conducted randomized phase II trial in patients with resectable non-small cell lung cancer treated with neoadjuvant durvalumab alone or with sub-ablative radiation. METHODS: We conducted a randomized phase II trial in patients with non-small cell lung cancer clinical stages I to IIIA who were randomly assigned to receive neoadjuvant durvalumab alone or with sub-ablative radiation (8Gyx3). Secondary end points included the safety of 2 cycles of preoperative durvalumab with and without radiation followed by pulmonary resection. Postoperative adverse events within 30 days were recorded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (version 4.0). RESULTS: Sixty patients were enrolled and randomly assigned, with planned resection performed in 26 patients in each arm. Baseline demographics and clinical variables were balanced between groups. The median operative time was similar between arms: 128 minutes (97-201) versus 146 minutes (109-214) (P = .314). There was no 30- or 90-day mortality. Grade 3/4 adverse events occurred in 10 of 26 patients (38%) after monotherapy and in 10 of 26 patients (38%) after dual therapy. Anemia requiring transfusion and hypotension were the 2 most common adverse events. The median length of stay was similar between arms (5 days vs 4 days, P = .172). CONCLUSIONS: In this randomized trial, the addition of sub-ablative focal radiation to durvalumab in the neoadjuvant setting was not associated with increased mortality or morbidity compared with neoadjuvant durvalumab alone.

Ten-Year Survival and Recurrence Patterns After Three-Field Lymph Node Dissection for Squamous Cell and Adenocarcinoma of the Esophagus.

OBJECTIVE: The aim was to determine the prevalence of metastases to the cervical and recurrent laryngeal cervicothoracic (CT) nodes as well as survival and recurrence patterns after esophagectomy with three-field lymph node dissection (TFD) in patients with predominately adenocarcinoma (AC) of the esophagus. BACKGROUND: Although esophagectomy with TFD is commonly practiced in Japan and Southeast Asia for squamous cell cancer (SCC) of the esophagus, there are only a handful of reports about its' utilization and survival benefit in North American patients. METHODS: This is a retrospective case series of patients who had an esophagectomy with TFD. The primary outcomes of interest were the prevalence of nodal metastases to the CT nodes as well as overall survival (OS) and disease-free survival. Secondary outcomes included time to recurrence, recurrence patterns, operative morbidity as well as 30 and 90-day mortality. RESULTS: Two hundred forty-two patients with esophageal cancer (AC: 67%) underwent esophagectomy with TFD. Metastases to the CT nodes were present in 56 patients (23%: AC 20% and SCC 30%). Positive CT nodes were present in 14% of pT1/T2 tumors and 30% of pT3 tumors. For the 56 patients with CT positive nodes, 5-year OS was 25% (AC:16%; SCC:39%). Fifteen of 56 (26.7%) patients with metastases to the CT nodes were alive and disease-free at a minimum of 5 years postoperatively. Ten-year OS was 43% for all patients with SCC and 28% for patients with AC. CONCLUSIONS: Metastases to the CT nodes are common in both SCC and AC of the esophagus and may be present in at least 14% of early lesions. Five-year survival is encouraging particularly for patients with esophageal SCC cancer.

Combined minimally invasive repair of pectus excavatum and robotically assisted mitral valve repair: A case report and considerations.

INTRODUCTION: Severe pectus excavatum (PE) is considered a relative contraindication to robotic cardiac surgery and information is lacking on surgical solutions to allow for a robotic approach in this setting. OBJECTIVE: We present a case of concomitant minimally invasive treatment of severe PE with initial pectus correction with Nuss bar insertion followed by robotically assisted mitral valve repair. METHODS: A multidisciplinary team planned and executed the operation. Thoracoscopic assessment at the onset of the case demonstrated mediastinal exposure was inadequate for robotic repar without PE correction. Forced sternal elevation demonstrated sternal laxity sufficient to provide adequate exposure. Nuss bars were placed and robotic repair proceeded uneventfully. RESULTS: The patient underwent successful concomitant minimally invasive PE and robotically assisted mitral repair. CONCLUSION: Successful combined minimally invasive pectus repair and robotic mitral valve can be achieved if sufficient chest wall laxity is present on forced sternal elevation and access sites are planned properly in a multidisciplinary approach.

Compartment syndrome as a novel complication of extended spectrum beta lactamase Escherichia coli necrotising soft tissue infection - A case report.

INTRODUCTION AND IMPORTANCE: Necrotising soft tissue infections (NSTI) encompass a group of destructive soft tissue disease processes which can involve skin, subcutaneous tissue, fascia and or muscle, associated with rapid spread along tissue planes and mortality. Clinical presentations include progressive pain, suppuration/necrosis and systemic toxicity with haemodynamic instability. While diagnosis is based on clinical findings it can be augmented with imaging. Treatment is typically in the form of resuscitation, immediate administration of broad spectrum intravenous antibiotics and urgent source control through radical surgical debridement. CASE PRESENTATION: An 82-year-old man presented with left forearm/hand pain and fevers in the context of immunocompromise. Examination found tense swelling of the left volar and dorsal forearm and hand, absent distal pulses with pain and paraesthesia over both surfaces. He underwent surgical debridement with fasciotomy and remained in intensive care with blood cultures revealing ESBL E. coli. CLINICAL DISCUSSION: Compartment syndrome is a rare complication of NSTI and its clinical presentation can obscure early diagnosis. ESBL E. coli is an uncommon pathogen to cause monomicrobial infection and must be accounted for when considering broad spectrum empirical antibiotic cover. CONCLUSION: Review of this case and the literature show a rare presentation of NSTI and highlights the importance of early diagnosis based on even a small index of suspicion. It also shows the key significance rationalisation of antibiotics as soon as practicable, given that even broad spectrum empirical cover can be inappropriate in the context of novel microorganisms, particularly in high risk patients.

Genomic and transcriptomic determinants of response to neoadjuvant therapy in rectal cancer.

The incidence of rectal cancer is increasing in patients younger than 50 years. Locally advanced rectal cancer is still treated with neoadjuvant radiation, chemotherapy and surgery, but recent evidence suggests that patients with a complete response can avoid surgery permanently. To define correlates of response to neoadjuvant therapy, we analyzed genomic and transcriptomic profiles of 738 untreated rectal cancers. APC mutations were less frequent in the lower than in the middle and upper rectum, which could explain the more aggressive behavior of distal tumors. No somatic alterations had significant associations with response to neoadjuvant therapy in a treatment-agnostic manner, but KRAS mutations were associated with faster relapse in patients treated with neoadjuvant chemoradiation followed by consolidative chemotherapy. Overexpression of IGF2 and L1CAM was associated with decreased response to neoadjuvant therapy. RNA-sequencing estimates of immune infiltration identified a subset of microsatellite-stable immune hot tumors with increased response and prolonged disease-free survival.

Prolactinoma with apoplexy in the context of thrombocytopaenia: A case report.

INTRODUCTION AND IMPORTANCE: Pituitary apoplexy is a clinical syndrome that occurs secondary to abrupt haemorrhage or infarction and can cause a presentation with headache, visual disturbances, and various neurological deficits. Pituitary apoplexy is a rare clinical syndrome that is often misdiagnosed or discovered late in its clinical course due to its relatively nonspecific clinical presentation. CASE PRESENTATION: The case describes patient with a giant prolactinoma which developed haemorrhagic progression in the context of previously undiagnosed coagulopathy from idiopathic thrombocytopaenia. Transcranial (rather than transnasal) surgery was performed for evacuation and debulking. CONCLUSION: The case highlights the management of an exceedingly large adenoma in the context of coagulopathy contributing to rapid clinical progression, as well as a positive clinical outcome in a patient with restored vision and pituitary function.

Safety of lung cancer surgery during COVID-19 in a pandemic epicenter.

BACKGROUND: The influence of SARS-CoV-2 on surgery for non-small cell lung cancer needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. OBJECTIVE: This study reports on the 90-day rate of infection as well as the morbidity and mortality of lung surgery for cancer in a tertiary care hospital located in a pandemic epicenter. METHODS: We conducted a retrospective review of a prospective database to identify consecutive patients who underwent lung cancer resection before (January 1, 2020-March 10, 2020, group 1; 57 patients) and during the COVID-19 pandemic (March 11, 2020-June 10, 2020, group 2; 41 patients). The primary end point was the occurrence of SARS-CoV-2 infection during the first 90-days after surgery. The secondary outcome measure was 90-day perioperative morbidity and mortality. RESULTS: Patient characteristics were not significantly different between the groups. Ninety-day COVID-19 infection rates was 7.3% (3 out of 41) for patients undergoing an operation during the pandemic and 3.5% (2 out of 57) in patients operated on immediately before the pandemic. All patients tested positive 10 to 62 days after the index surgical procedure following hospital discharge. Four COVID-19-positive patients were symptomatic and 4 out of 5 patients required hospitalization, were men, previous or current smokers with hyperlipidemia, and underwent a sublobar resection. Univariate analysis did not identify any differences in postoperative complications before or during the COVID-19 pandemic. Ninety-day mortality was 5% (2 out of 41) for lung cancer surgery performed during the pandemic, with all deaths occurring due to COVID-19, compared with 0% (0 out of 57) mortality in patients who underwent an operation before the pandemic. CONCLUSIONS: During the COVID-19 pandemic, COVID-19 infections occurred in 7.3% of patients who underwent surgery for non-small cell lung cancer. In this series all infections occurred after hospital discharge. Our results suggest that COVID-19 infections occurring within 90 days of surgery portend a 40% mortality, warranting close postoperative surveillance.

Extent of Resection Influences Survival in Early-Stage Lung Cancer With Occult Nodal Disease.

BACKGROUND: Minimal literature exists evaluating the impact of the extent of resection on survival in patients with small, early-stage non-small cell lung cancer (NSCLC) found to have occult nodal disease. We hypothesized that sublobar resection has comparable overall survival to patients undergoing lobectomy for clinical stage IA NSCLC that harbors occult nodal disease. METHODS: The National Cancer Database was reviewed for identification of patients with clinical stage IA NSCLC who underwent wedge resection, segmentectomy, or lobectomy and were found to have occult nodal disease. Overall survival was compared between groups, and a multivariate Cox regression model identified factors associated with worse survival. RESULTS: Occult nodal disease occurred in 6.1% of all patients with clinical stage IA disease undergoing resection. Patients undergoing wedge resection and segmentectomy found to have occult nodal disease were older (67.6 ± 9.6 years of age vs 66.1 ± 9.3 years of age vs 65.6 ± 9.5 years of age; P = .004) and had more advanced pathologic stage (pStage III: 68.7% vs 50.5% vs 41.5%; P < .001) than those receiving lobectomy. There was no difference in the median overall survival between segmentectomy and lobectomy (68.5 months vs 57.6 months; P = .200). However, wedge resection was independently associated with worse overall survival when controlling for other preoperative variables (hazard ratio, 1.23; 95% confidence interval, 1.01-1.51; P = .042). CONCLUSIONS: Review of the National Cancer Database suggests that there is no improvement in overall survival in patients undergoing lobectomy vs segmentectomy in carefully selected patients with clinical stage IA NSCLC harboring occult nodal disease. However, those undergoing wedge resection may have worse overall survival than those undergoing both lobectomy and segmentectomy.

Lung Cancer Stage Shift as a Result of COVID-19 Lockdowns in New York City, a Brief Report.

INTRODUCTION: The COVID-19 pandemic reached New York City in early March 2020 resulting in an 11-week lockdown period to mitigate further spread. It has been well documented that cancer care was drastically affected as a result. Given New York City's early involvement, we attempted to identify any stage shift that may have occurred in the diagnoses of non-small cell lung cancer (NSCLC) at our institution as a result of these lockdowns. PATIENTS AND METHODS: We conducted a retrospective review of a prospective database of lung cancer patients at our institution from July 1, 2019 until March 31, 2021. Patients were grouped by calendar year quarter in which they received care. Basic demographics and clinical staging were compared across quarters. RESULTS: Five hundred and fifty four patients were identified that underwent treatment during the time period of interest. During the lockdown period, there was a 50% reduction in the mean number of patients seen (15 ± 3 vs. 28 ± 7, P = .004). In the quarter following easing of restrictions, there was a significant trend towards earlier stage (cStage I/II) disease. In comparison to quarters preceding the pandemic lockdown, there was a significant increase in the proportion of patients with Stage IV disease in the quarters following phased reopening (P = .026). CONCLUSION: After a transient but significant increase in Stage I/II disease with easing of restrictions there was a significant increase in patients with Stage IV disease. Extended longitudinal studies must be conducted to determine whether COVID-19 lockdowns will lead to further increases in the proportion of patients with advanced NSCLC.
