    Abstract Objectives: There is little data describing the outcomes for patients who develop local recurrences after stereotactic body radiation therapy (SBRT), a standard-of-care treatment for patients with early-stage non-small cell lung cancer. One emerging option is salvage lobectomy. We investigated trends in the use of salvage lobectomy after SBRT and described patient outcomes using a nationally representative sample.
    Methods: This is a retrospective study using the National Cancer Database of patients with non-small cell lung cancer diagnosed from 2004 to 2017. We used descriptive statistics to describe patients who underwent salvage lobectomy. Kaplan-Meier analysis was used to estimate overall survival (OS). Cox proportional modeling was used to identify factors associated with OS.
    Results: We identified 276 patients who underwent salvage lobectomy. Ninety-day mortality was 0%. The median survival time for the cohort was 50 months (95% CI, 44 to 58). Median follow-up was 65 months (Interquartile Range: 39 to 96). The factors associated with decreased OS include squamous cell histology (hazard ratio (HR)=1.72, P =0.005) and high grade (1.50, P =0.038). Increased OS was associated with lobectomy performed between 3 and 6 months after SBRT (HR=0.53, P =0.021), lobectomy performed >6 months after SBRT (HR=0.59, P =0.015), and female sex (HR=0.56, P =0.004).
    Conclusions: Salvage lobectomy after local failures of SBRT was associated with no perioperative mortality and favorable long-term outcomes. Our data suggest that lobectomy performed within 3 months of SBRT is associated with worse OS.

    Abstract Background: A standard of care for nonmetastatic esophageal cancer is trimodality therapy consisting of neoadjuvant chemoradiation and esophagectomy, with evidence for improved overall survival versus surgery alone in the ChemoRadiotherapy for Oesophageal cancer followed by Surgery Study (CROSS) trial. Patients who receive treatment with curative intent but are poor candidates for or decline surgery receive definitive bimodality therapy. Literature characterizing patients who receive bimodality therapy compared to trimodality therapy, and their relative outcomes, is sparse, especially among patients who are too old or too frail to qualify for clinical trials. In this study, we assess a single-institution real-world dataset of patients receiving bimodality and trimodality management.
    Methods: Patients treated for clinically resectable, nonmetastatic esophageal cancer between 2009 and 2019 who received bimodality or trimodality therapy were reviewed, generating a dataset of 95 patients. Clinical variables and patient characteristics were assessed for association with modality on multivariable logistic regression. Overall, relapse-free, and disease-free survival were assessed with Kaplan-Meier analyses and Cox proportional modeling. For patients nonadherent to planned esophagectomy, reasons for nonadherence were recorded.
    Results: Bimodality therapy was associated with greater age-adjusted comorbidity index, worse performance status, higher N-stage, presenting symptom other than dysphagia, and held chemotherapy cycles on multivariable analysis. Compared to bimodality therapy, trimodality therapy was associated with higher overall (3-year: 62%
    Conclusions: Patients receiving trimodality therapy were observed to have superior overall survival compared to bimodality therapy. Patient preference for organ-preserving therapies appears to impact resection rate; further characterization of patient decision-making may be helpful. Our results suggest patients who wish to prioritize overall survival should be encouraged to pursue trimodality therapy and obtain early consultation with surgery. Development of evidence-based interventions to physiologically prepare patients before and during neoadjuvant therapy as well as efforts to optimize the tolerability of the chemoradiation plan are warranted.

    Abstract Background: Robot-assisted esophagectomy (RAE), video-assisted minimally invasive esophagectomy (VAMIE), and open esophagectomy (OE) all have significant roles in the management of esophageal cancer (EC). Few studies have compared efficacy and safety between RAE, VAMIE, and OE for resectable EC after neoadjuvant treatment. Therefore, this study aimed to explore the short-term outcomes between RAE, VAMIE, and OE for resectable EC after neoadjuvant treatment.
    Methods: Ninety-eight patients were consecutively enrolled who underwent esophagectomy. A retrospective study was performed including 98 consecutive patients treated from January 2021 to August 2022 who received neoadjuvant treatment (including immunochemotherapy and chemoradiotherapy) followed by RAE, VAMIE or OE. Evaluated endpoints in the present study consisted of pathological outcomes, intraoperative and postoperative outcomes, as well as postoperative complications.
    Results: No significant differences were seen in the operating time, blood loss, length of intensive care unit (ICU) stay, R0 resection, and number of dissected lymph nodes between the three RAE, VAMIE, or OE groups. The achievement rate of right recurrent laryngeal nerve (RLN) lymph node removal (P=0.01) and the total cost (P<0.001) were higher in RAE. The postoperative hospital stay of OE was longer than the other two groups (P<0.05). There were no significant differences in postoperative complications.
    Conclusions: Compared to VAMIE, no clear benefit exists for RAE in the treatment of resectable EC after neoadjuvant therapy. OE resulted in a longer hospital stay. Although the rate of successful right RLN node removal was higher with RAE, the clinical relevance for this is yet unclear.

    Abstract Background: A survey of medical oncologists (MOs), radiation oncologists (ROs), and surgical oncologists (SOs) who are experts in the management of patients with metastatic colorectal cancer (mCRC) was conducted to identify factors used to consider metastasis-directed therapy (MDT).
    Materials and methods: An online survey to assess clinical factors when weighing MDT in patients with mCRC was developed based on systematic review of the literature and integrated with clinical vignettes. Supporting evidence from the systematic review was included to aid in answering questions.
    Results: Among 75 experts on mCRC invited, 47 (response rate 62.7%) chose to participate including 16 MOs, 16 ROs, and 15 SOs. Most experts would not consider MDT in patients with 3 lesions in both the liver and lung regardless of distribution or timing of metastatic disease diagnosis (6 vs. 36 months after definitive treatment). Similarly, for patients with retroperitoneal lymph node and lung and liver involvement, most experts would not offer MDT regardless of timing of metastatic disease diagnosis. In general, SOs were willing to consider MDT in patients with more advanced disease, ROs were more willing to offer treatment regardless of metastatic site location, and MOs were the least likely to consider MDT.
    Conclusions: Among experts caring for patients with mCRC, significant variation was noted among MOs, ROs, and SOs in the distribution and volume of metastatic disease for which MDT would be considered. This variability highlights differing opinions on management of these patients and underscores the need for well-designed prospective randomized trials to characterize the risks and potential benefits of MDT.

    Abstract With increased therapeutic options in rectal cancer, a central question has become how to tailor therapy to patient preferences to avoid both over and under treatment. Total Neoadjuvant Therapy (TNT), defined as delivering all planned chemotherapy and radiation therapy (RT) before surgery, was developed with the primary goal of improving overall survival through early elimination of micrometastatic disease. In this narrative review assessing patients with operable adenocarcinoma of the rectum, we sought to evaluate TNT versus alternative options with regard to both quality of life (QoL) and oncologic outcomes. Survey data of patient preferences reveal that an increased focus on QoL when discussing options is essential. While evidence favors TNT improving distant metastases-free survival, this has not yet translated to a clear OS benefit. The improved pathologic complete response rate with TNT compared to short course RT or chemoradiation alone suggests proceeding to surgery might result in overtreatment, lending support to a watch-and-wait option for patients with a goal for nonoperative management if a clinical complete response is achieved. Similarly, for select low-risk patients, surgery may be the only local therapy required allowing for safe omission of RT. In the treatment of rectal cancer, the future appears to be moving toward one local therapy. As an alternative to TNT, there is growing support for the concept we define herein as total definitive therapy instead: chemoradiation followed by consolidation chemotherapy, saving surgery only for incomplete responders rather than as part of the initial treatment plan. Also, selective use of RT should be considered for low-risk patients. By thoroughly assessing how these treatment de-escalation options compare to more traditional treatment algorithms, this narrative review provides guidance on how to honor patient preferences for QoL by avoiding treatments that might offer negligible benefits in oncologic outcomes.

    Abstract Meningeal melanocytomas are extremely rare, pigmented tumors of the CNS. They generally carry a favorable prognosis, although recurrence and transformation into the more aggressive malignant melanoma have been reported. We present a case of a patient who reported constipation and abdominal pain around the umbilicus, which progressed into cord compression with lower extremity weakness and gait instability. Spinal MRI revealed a tumor at the level of T11, and she underwent gross total resection of the mass. Pathology demonstrated a meningeal melanocytoma with intermediate features. She received postoperative radiation therapy and had stable disease for 3 years, at which time she developed new weakness and drop metastases. This case represents a rare presentation of a rare disease, in which a spinal cord tumor presented with constipation and abdominal distress. Intradural extramedullary tumors of the thoracic spine are most commonly nerve sheath tumors or meningiomas, but rare entities such as melanocytomas can present in this location; even more rarely, these tumors can have an aggressive course with delayed recurrence.

    Abstract Objectives: Data describing outcomes for patients with early stage lung cancer who undergo expectant management is lacking, despite evidence of a sub-population with indolent malignancies. We used the National Cancer Data Base (NCDB) to identify factors associated with active surveillance for early stage lung cancer. Additionally, we sought to describe outcomes of three different care plans: active surveillance, no treatment, and Stereotactic Body Radiation Therapy (SBRT).
    Methods: Patients diagnosed in 2010 to 2017 with early stage lung cancer who underwent active surveillance, no treatment, and SBRT were retrospectively identified in the NCDB. Multinomial logistic regression was used to assess care plan selection. Kaplan Meier analysis was used to assess overall survival (OS).
    Results: We identified 30,107 patients that met our inclusion criteria: 838 (3%) underwent active surveillance, 6388 patients (21%) received no treatment, and 22,881 (76%) underwent SBRT. Black race (relative risk ratio (RRR): 1.66) and older age (RRR: 1.02) were significant positive predictors of active surveillance selection. Conversely, higher tumor stage (RRR: 0.26) and squamous cell carcinoma (RRR: 0.35) were significant negative predictors of active surveillance selection. Kaplan Meier analysis revealed a longer median OS associated with active surveillance compared to no treatment at 49.3 months versus 26.5 months, respectively. SBRT OS was 43.1 months.
    Conclusions: We identified a population of lung cancer patients who underwent expectant management with favorable outcomes. Additionally, we identified factors associated with active surveillance selection. The selection of active surveillance over no treatment was associated with significantly longer OS.
