The Impact of Enhanced Recovery on Long-Term Survival in Rectal Cancer.

INTRODUCTION: Implementing perioperative interventions such as enhanced recovery pathways (ERPs) has improved short-term outcomes and minimized length of stay. Preliminary evidence suggests that adherence to the enhanced recovery after surgery protocol may also enhance 5-year cancer-specific survival (CSS) in colorectal cancer surgery. This retrospective study presents long-term survival outcomes and disease recurrence from a high-volume, single-center practice. METHODS: All patients over 18 years of age diagnosed with rectal adenocarcinoma and undergoing elective minimally invasive surgery (MIS) were retrospectively reviewed between February 2005 and April 2018. Relevant data were extracted from Mayo electronic records and securely stored in a database. Short-term morbidity and long-term oncological outcomes were compared between patients enrolled in ERP and those who received non-enhanced care. RESULTS: Overall, 600 rectal cancer patients underwent MIS, of whom 320 (53.3%) were treated according to the ERP and 280 (46.7%) received non-enhanced care. ERP was associated with a decrease in length of stay (3 vs. 5 days; p < 0.001) and less overall complications (34.7 vs. 54.3%; p < 0.001). The ERP group did not show an improvement in overall survival (OS) or disease-free survival (DFS) compared with non-enhanced care on multivariable (non-ERP vs. ERP OS: hazard ratio [HR] 1.268, 95% confidence interval [CI] 0.852-1.887; DFS: HR 1.050, 95% CI 0.674-1.635) analysis. CONCLUSION: ERP was found to be associated with a reduction in short-term morbidity, with no impact on long-term oncological outcomes, such as OS, CSS, and DFS.

Factors Associated With Long-term Survival in Children With Bronchial and Lung Carcinoid Tumors.

BACKGROUND AND AIMS: Bronchial carcinoids are rare in children and the treatment is based on tumor behavior in adults. The purpose of this study was to determine factors and management strategies associated with long-term survival in the pediatric population using a national cohort. METHODS: Patients aged ≤20 years with bronchial carcinoid tumors were identified in the 2004-2020 National Cancer Database using ICD-O-3 codes. Tumor characteristics and management were compared among typical (TC) and atypical (AC) histological subtypes using Chi-square and Fisher's exact tests. Kaplan-Meier and univariate Cox proportional hazards analyses were used to assess survival. RESULTS: Of 273 patients, 251 (92%) had TCs, and 22(8%) had ACs. The median (IQR) age was 18 (16,19) years. Most patients underwent lobectomy or bilobectomy (67%), followed by sublobar resection (17%), no resection or bronchoscopic excision or ablation (8%), and pneumonectomy (7.7%). Margins were negative in 96%. Lymph node (LN) assessment was performed in 216 patients (84%) with a median (IQR) of 7(3,13) LNs, and 50 (23%) had ≥1 positive LN. There was no difference in age, resection, margin status, LN assessment, or positivity between TC and AC (all p > 00.05). Detection of nodal metastasis did not increase beyond the resection of 1-3 LNs (p = 0.72). Ten-year survival was worse for AC than TC (79% (41, 100) vs 98% (95, 100), HR = 6.9 (95% CI: 1.2-38.3, p = 0.03). Ten-year survival among those with and without LN assessment was 97% (94, 100) vs 91% (81, 100), HR = 4.0, 95% CI: 0.8-19.9, p = 0.09). There were no deaths in those with negative LN while 10-year survival was 89% (72, 100) in those with ≥1 positive LN. CONCLUSION: Among children with bronchial carcinoids, survival is excellent with TC or negative LN. Atypical histology and positive LN have poor survival and should prompt close monitoring. These risk factors may be missed in the absence of surgical resection and lymph node sampling. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Retrospective Study.

Unveiling the Hidden Consequences: Initial Impact of COVID-19 on Colorectal Cancer Operation.

BACKGROUND: The COVID-19 pandemic has severely affected healthcare systems globally, resulting in significant delays and challenges in various medical treatments, particularly in cancer care. This study aims to investigate the repercussions of the pandemic on surgical interventions for colorectal cancer (CRC) in the US, using data from the National Cancer Database. STUDY DESIGN: We conducted a retrospective analysis of the National Cancer Database, encompassing adult patients who underwent surgical procedures for colon and rectal cancer in 2019 (pre-COVID) and 2020 (COVID). We examined various demographic and clinical variables, including patient characteristics, tumor staging, surgical approaches, and socioeconomic factors. RESULTS: The analysis included 105,517 patients, revealing a 17.3% reduction in surgical cases during the initial year of the pandemic. Patients who underwent surgery in 2020 displayed more advanced clinical and pathological tumor stages compared to those treated in 2019. After diagnosis, no delay was reported in the treatment. Patients operated during the pandemic, Black patients, uninsured, and Medicaid beneficiaries had worse stage colon and rectal cancer, and individuals with lower incomes bore the burden of advanced colon cancer. CONCLUSIONS: The impact of the COVID-19 pandemic on CRC surgery transcends a mere decline in case numbers, resulting in a higher prevalence of patients with advanced disease. This study underscores the exacerbated disparities in cancer care, particularly affecting vulnerable populations. The COVID-19 pandemic has left a significant and enduring imprint on CRC surgery, intensifying the challenges faced by patients and healthcare systems. Comprehensive studies are imperative to comprehend the long-term consequences of delayed screenings, diagnoses, and treatments as healthcare planning for the future must consider the unintended repercussions of pandemic-related disruptions.

Accuracy of a Cancer Registry Versus Clinical Care Team Chart Abstraction in Identifying Cancer Recurrence.

Objective: To evaluate the completeness and reliability of recurrence data from an institutional cancer registry for patients with head and neck cancer. Patients and Methods: Recurrence information was collected by radiation oncology and otolaryngology researchers. This was compared with the institutional cancer registry for continuous patients treated with radiation therapy for head and neck cancer at a tertiary cancer center. The sensitivity and specificity of institutional cancer registry data was calculated using manual review as the gold standard. False negative recurrences were compared to true positive recurrences to assess for differences in patient characteristics. Results: A total of 1338 patients who were treated from January 1, 2010, through December 31, 2017, were included in a cancer registry and underwent review. Of them, 375 (30%) had confirmed cancer recurrences, 45 (3%) had concern for recurrence without radiologic or pathologic confirmation, and 31 (2%) had persistent disease. Most confirmed recurrences were distant (37%) or distant plus locoregional (29%), whereas few were local (11%), regional (9%), or locoregional (14%) alone. The cancer registry accuracy was 89.4%, sensitivity 61%, and specificity 99%. Time to recurrence was associated with registry accuracy. True positives had recurrences at a median of 414 days vs 1007 days for false negatives. Conclusion: Currently, institutional cancer registry recurrence data lacks the required accuracy for implementation into studies without manual confirmation. Longer follow-up of cancer status will likely improve sensitivity. No identified differences in patients accounted for differences in sensitivity. New, ideally automated, data abstraction tools are needed to improve detection of cancer recurrences and minimize manual chart review.

Sublobar Resection, Stereotactic Body Radiation Therapy, and Percutaneous Ablation Provide Comparable Outcomes for Lung Metastasis-Directed Therapy.

BACKGROUND: Prolonged survival of patients with metastatic disease has furthered interest in metastasis-directed therapy (MDT). RESEARCH QUESTION: There is a paucity of data comparing lung MDT modalities. Do outcomes among sublobar resection (SLR), stereotactic body radiation therapy (SBRT), and percutaneous ablation (PA) for lung metastases vary in terms of local control and survival? STUDY DESIGN AND METHODS: Medical records of patients undergoing lung MDT at a single cancer center between January 2015 and December 2020 were reviewed. Overall survival, local progression, and toxicity outcomes were collected. Patient and lesion characteristics were used to generate multivariable models with propensity weighted analysis. RESULTS: Lung MDT courses (644 total: 243 SLR, 274 SBRT, 127 PA) delivered to 511 patients were included with a median follow-up of 22 months. There were 47 local progression events in 45 patients, and 159 patients died. Two-year overall survival and local progression were 80.3% and 63.3%, 83.8% and 9.6%, and 4.1% and 11.7% for SLR, SBRT, and PA, respectively. Lesion size per 1 cm was associated with worse overall survival (hazard ratio, 1.24; P = .003) and LP (hazard ratio, 1.50; P < .001). There was no difference in overall survival by modality. Relative to SLR, there was no difference in risk of local progression with PA; however, SBRT was associated with a decreased risk (hazard ratio, 0.26; P = .023). Rates of severe toxicity were low (2.1%-2.6%) and not different among groups. INTERPRETATION: This study performs a propensity weighted analysis of SLR, SBRT, and PA and shows no impact of lung MDT modality on overall survival. Given excellent local control across MDT options, a multidisciplinary approach is beneficial for patient triage and longitudinal management.
