Comparative effectiveness of perioperative physical activity in older adults with lung cancer and their family caregivers: design of a multicenter pragmatic randomized trial.

BACKGROUND: With a median age at diagnosis of 70, lung cancer remains a significant public health challenge for older Americans. Surgery is a key component in treating most patients with non-metastatic lung cancer. These patients experience postoperative pain, fatigue, loss of respiratory capacity, and decreased physical function. Data on quality of life (QOL) in older adults undergoing lung cancer surgery is limited, and few interventions are designed to target the needs of older adults and their family caregivers (FCGs). The primary aim of this comparative effectiveness trial is to determine whether telephone-based physical activity coaching before and after surgery will be more beneficial than physical activity self-monitoring alone for older adults and their FCGs. METHODS: In this multicenter comparative effectiveness trial, 382 older adults (≥ 65 years) with lung cancer and their FCGs will be recruited before surgery and randomized to either telephone-based physical activity coaching or physical activity self-monitoring alone. Participants allocated to the telephone-based coaching comparator will receive five telephone sessions with coaches (1 pre and 4 post surgery), an intervention resource manual, and a wristband pedometer. Participants in the self-monitoring only arm will receive American Society of Clinical Oncology (ASCO) physical activity information and wristband pedometers. All participants will be assessed at before surgery (baseline), at discharge, and at days 30, 60, and 180 post-discharge. The primary endpoint is the 6-minute walk test (6MWT) at 30 days post-discharge. Geriatric assessment, lower extremity function, self-reported physical function, self-efficacy, and QOL will also be assessed. DISCUSSION: The trial will determine whether this telephone-based physical activity coaching approach can enhance postoperative functional capacity and QOL outcomes for older adults with lung cancer and their FCGs. Trial results will provide critical findings to inform models of postoperative care for older adults with cancer and their FCGs. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT06196008.

Per-Oral Endoscopic Myotomy for Esophagogastric Junction Outflow Obstruction: A Multicenter Pilot Study.

Esophagogastric junction outflow obstruction (EGJOO) is a rare but increasingly recognized diagnosis as described by The Chicago Classification of Esophageal Motility Disorders version 3.0 (version 3.0).1 On high-resolution manometry (HRM), EGJOO is characterized by increased integrated relaxation pressure (IRP) of the lower esophageal sphincter (LES), yet with some preserved esophageal peristalsis.2-4 Little consensus exists on the preferred therapeutic approach.3 Although conceptually per-oral endoscopic myotomy (POEM) should address the measurable dysfunction in the LES, few data exist to support this.5 Thus, we aimed to evaluate the safety and efficacy of POEM for the treatment of symptomatic EGJOO.

Weight Bias: Examining Achalasia Therapy in the Obese Patient.

We hypothesize that obesity is a common diagnosis in those with achalasia at our institution but time to diagnosis and treatment is longer compared to normal weight counterparts due to implicit bias. We retrospectively reviewed all adult patients between 1/1/2013 and 6/31/2020 with a diagnosis of achalasia. Demographics, comorbidities, Eckardt scores, interventions, complications, time to consult, duration of symptoms, and follow-up were evaluated. More than half of the patients were seen in the most recent 2 years following POEM introduction and 138 had available BMI data. 46 were obese (33%) and 92 were non-obese (67%). Obese patients reported a shorter duration of symptoms prior to seeking treatment 12 versus 24 months. There was no difference in time to intervention or procedure offered. There was a non-significant trend toward higher leak (11 vs 5%) and overall complication rate (19 vs 17%) in obese patients. In follow-up 98 patients had BMI data. There was a a significant difference in mean BMI change -1.2 +/- 4.2 kg/m2 in obese patients and +0.1 +/- 2.1 kg/m2 in normal weight patients. One year follow-up was available in 16 (47%) obese and 25 (33%) non-obese patients and showed a non-significant trend toward greater weight gain in the normal/overweight group (+3.2 +/- 1.1 kg/m2) compared to obese (+2.0 +/- 3.5 kg/m2). Obese patients with achalasia have unique considerations. Duration of symptoms may be shorter in the obese patient with esophageal dysphagia. We noted trends toward greater weight gain following interventions in non-obese patients with equivalent complication rates.

Impedance Planimetry and the Changing Paradigm of Esophageal Dysphagia.

OBJECTIVES: Patients presenting with dysphagia can encounter a pathway to therapy and relief that is expensive and frustrating. High resolution impedance planimetry (HRIP) is a new mechanism for enhancing and possibly hastening that process. A balloon with integrated pressure sensors is utilized to measure luminal geometry and pressure by volume-controlled distention. Esophagogastric junction (EGJ) distensibility and body contractility are assessed at the time of other endoscopic procedures. Here we describe a single-center experience utilizing HRIP in the endoscopic evaluation of patients presenting with dysphagia. METHODS: A prospectively maintained registry of patients undergoing impedance planimetry assessments at an academic medical center was queried for demographics, procedural details, and patient-reported outcomes. RESULTS: Data was reviewed for 122 procedures performed by two providers. HRIP was performed in 63 (52%) patients for initial dysphagia assessment, 36 (30%) for follow-up assessment, and 20 (16%) as a procedural adjunct at the time of other planned procedures. HRIP contractile response was characterized as normal in 36%, absent in 32%, and diminished/disorganized in 14%. These results motivated clinical planning for surgical referral in 7 (5%) patients, 31 (26%) additional testing, and 82 (68%) continued medical management and follow-up. DISCUSSION: HRIP is an emerging endoscopic modality which can streamline diagnostic work-up and therapeutic planning for patients with symptomatic dysphagia. Using functional esophageal assessment at the time of other diagnostic and therapeutic procedures, HRIP may expedite care and lead to improved patient satisfaction and clinical outcomes.

Single Institution Experience of Stereotactic Body Radiation Therapy in Non-small Cell Lung Cancer: Comparison of Two Dose Regimes and a Perspective on Ideal Dose Regimens.

Introduction Stereotactic body radiation therapy (SBRT) is an effective treatment for early-stage non-small cell lung cancer (NSCLC) patients who are either medically inoperable or who decline surgery. SBRT improves tumor control and overall survival (OS) in medically inoperable, early-stage, NSCLC patients. In this study, we investigated the effectiveness of two different SBRT doses commonly used and present our institutional experience. Purpose To determine the clinical outcomes between two treatment regiments (50 Gray [Gy] vs. 55 Gy in five fractions) among Stage I NSCLC patients treated with SBRT at a state academic medical center. Methods We performed a retrospective analysis of 114 patients with Stage I (T1-2 N0 M0) NSCLC treated at a state academic medical center between October 2009 and April 2019. Survival analyses with treatment regimens of 50 Gy and 55 Gy in five fractions were conducted to detect any improvement in outcomes associated with the higher dose. The primary endpoints of this study included OS, local control (LC), and disease-free survival (DFS). Log-rank test and the Kaplan-Meier method were used to analyze the survival curves of the two treatment doses. The SPSS v.24.0 (IBM Corp., Armonk, NY, USA) was used for statistical analyses. Results The 114 early-stage NSCLC patients (median age, 68 years; range 12 to 87 years) had a median follow-up of 25 months (range two to 86 months). The number of males (n = 72; 63.2 %) exceeded the number of females (n = 42; 36.8 %). The majority of patients in this study were Caucasians (n = 68; 59.6 %) and 46 patients were African Americans (40.4 %). Two-thirds of the patients (n = 76; 66.7 %) were treated with 50 Gy in five fractions, and 38 patients (33.3 %) with 55 Gy in five fractions. The one-, two-, and three-year OS and DFS rates were improved in the patients treated with 55 Gy [OS, 81.7 % vs. 72.8 %; 81.7 % vs. 58.9 %; 81.7 % vs. 46.7 % (p = 0.049)], [DFS, 69.7 % vs. 69.7 %; 61.9 % vs. 55.7 %; 61.9 % vs. 52.0 % (p = 0.842)], compared to those treated with 50 Gy. Adenocarcinoma was the most common histology in both groups (51.3 % and 68.4 %). Failure rates were elevated for the 50 Gy regimen [39 (34.2 %) vs. 12 (8.5 %)]. Three year control rates were (66.3 % vs. 96.6 %; p = 0.002) local control; (63.3 % vs. 94.4 %; p = 0.000) regional control; and (65.7 % vs. 97.1 %; p = 0.000) distant control, compared to those treated with 55 Gy. Conclusion Early-stage NSCLC patients treated with SBRT 55 Gy in five fractions did better in terms of local control, overall survival, and disease-free survival rates compared to the 50 Gy in five fractions group.

Substernal reconstruction following esophagectomy: operation of last resort?

BACKGROUND: The posterior mediastinum is the preferred location for reconstruction following esophagectomy. Occasionally alternative routes are required. We examined patient outcomes of esophageal reconstruction in order to determine whether substernal reconstruction (SR) is an equivalent alternative to orthotopic placement. METHODS: Following IRB approval, we performed a retrospective review of all patients who underwent an esophagectomy from 1988-2014. Only patients reconstructed with a gastric conduit and cervical anastomosis by either substernal or posterior mediastinal (PM) routes were included in the study. Endpoints assessed included anastomotic leak rate, post-operative complications, reoperation, hospital length of stay, and 30- and 90-day mortality. RESULTS: Thirty-three patients underwent SR and 182 had a PM gastric conduit with cervical anastomosis. The SR pathology was predominantly benign while PM was mostly malignant. Sixteen SR patients had a delayed reconstruction after prior diversion. Mean hospital LOS was longer in the SR group (P<0.001). There was no significant difference in 30- and 90-day mortality. PM patients had significantly fewer respiratory complications (P<0.04), reoperations (P<0.04), and transfusions (P<0.0001) and a trend towards fewer anastomotic leaks (17.1% vs. 30.3%; P<0.09). CONCLUSIONS: This single institution experience demonstrated no significant difference in mortality between substernal and PM reconstruction following esophagectomy. However, SR was associated with significantly increased LOS and morbidity, including a trend toward increased anastomotic leaks. SR reconstruction should probably be considered an option of last resort.

The role of induction therapy.

The incidence of esophageal cancer has been steadily increasing. The 5-year survival of esophageal cancer has minimally improved over the past 30 years. In this article, we review the management of esophageal cancer, focusing on the literature investigating the role of induction chemotherapy and radiation therapy.

Traumatic disruption of the abdominal wall: lap-belt injuries in children.

Traumatic abdominal wall hernia (TAWH) from high speed mechanism is a unique finding in adult trauma, and exceedingly rare in pediatrics. The majority of reports are of low-speed "handlebar" hernias associated with direct injury by bicycle handlebars. We report a series of three pediatric patients in motor vehicle collisions (MVC) who experienced TAWH by lap-belt and associated intra-abdominal injuries necessitating immediate operative intervention. Different operative approaches were used in each case to manage the varying types of disruptions. This adds to the pediatric literature the largest series of its kind.
