RESUMO

BACKGROUND: Advanced age is considered a risk factor for lung transplantation (LTX). We sought to evaluate the long-term outcomes of LTX in the septuagenarian. METHODS: LTX recipients in the UNOS transplant registry (May 1, 2005-June 12, 2020) were stratified into 18-59, 60-69, and > = 70 years of age. Recipient and transplant characteristics were evaluated for survival, cause of death (COD), length of stay (LOS), and complications. A Kaplan-Meier analysis examined long-term survival for all patients stratified by age, specifically looking at cause of death. RESULTS: A total of 27 632 recipients were identified. As recipients aged, we found a decrease in proportion of cystic fibrosis and an increase in restrictive disease while obstructive disease peaked in the 60-69yo cohort (P < .001). Septuagenarians had higher rates of single LTX, male gender, and white race (P < .001). Older recipients had significantly longer donor recovery distances traveled with paradoxical shorter ischemic times, shorter hospital LOS and were transplanted at higher volume centers. There was no difference with in-hospital mortality among groups (P = .5). Acute rejection during initial hospitalization, rejection within 1 year, and post-transplant dialysis incidence decreased with age. Graft failure was a common COD in younger patients while malignancy and cardio/cerebrovascular diseases were common COD in > = 70yo. CONCLUSION: Select septuagenarian LTX candidates may be safely transplanted with relatively few complications. Immunosenescence and conditions of the aged are likely contributing factors to the decreased rejection and graft failure observations. Septuagenarians should not be excluded from LTX consideration based solely on age. Transplantation in septuagenarians should only be done in very selected patients (screened for malignancies and atherosclerotic disease) and these recipients should be carefully followed after transplantation because of these risk factors.

RESUMO

BACKGROUND: The role of neoadjuvant therapy (NT) for ampullary carcinoma (AC) has not been clearly established. METHODS: Patients who underwent pancreatoduodenectomy for AC between 2004 and 2016 were identified in the National Cancer Database. Overall survival (OS) was compared between those who received NT before resection and those who underwent surgery first (SF). Propensity score matching (PSM) was performed using age, pathologic T and N stage, and tumor differentiation. RESULTS: Among 8688 patients with AC, 175 (2.0%) received NT before surgery. While patients who received NT were younger (p = .022) and more likely to have nodal metastasis (43.3% vs. 35.1%, p < .001), there was no difference in OS on univariate (43 vs. 33 months; hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 0.88-1.37, p = .401) or multivariate (HR: 1.09, 95% CI: 0.88-1.36, p = .416) analysis between groups. After PSM, there remained no difference in OS between NT or SF groups on univariate (37 vs. 32 months; HR: 1.20, 95% CI: 0.87-1.64, p = .350) or multivariate (HR: 0.99, 95% CI: 0.71-1.38, p = .943) analysis. CONCLUSION: NT followed by surgery was not associated with improved survival outcomes compared with SF among patients with localized AC. While NT is an acceptable alternative for patients with advanced disease, SF should remain the standard of care.

RESUMO

PURPOSE: Neoadjuvant therapy (NT) is increasingly utilized for patients with localized pancreatic ductal adenocarcinoma (PDAC). Patients with cancer have high information needs and the Internet has materialized as a leading source of information for many patients. Nevertheless, little is known about the availability, accessibility, quality, and readability of online information regarding NT for PDAC. METHODS: A search of online patient informational materials (PIMs) pertaining to NT for PDAC was conducted using a combination of common search engines and browsers. Two independent researchers evaluated the readability, quality, and availability of unique PIMs from the top 25 websites from each search using validated measures. RESULTS: Among the 130 websites retrieved, 46 (35.4%) unique PIMs focused on treatment of PDAC. Only 30 (23%) mentioned NT as a possible treatment option. Downstaging was the rationale for NT mentioned in the majority (90%) of websites. The mean quality and reliability of the 30 PIMs, assessed using the DISCERN instrument, was 3.3 ± 0.7, suggesting moderate quality/reliability. The mean readability score, assessed using the SMOG Grade tool, was 10.96 ± 1.49, which is equivalent to an 11th grade reading level. CONCLUSION: The low availability, poor readability, and moderate quality of online informational materials regarding NT for PDAC highlight the need for new patient-centered resources to educate patients and caregivers on an increasingly utilized treatment strategy for localized PDAC.

RESUMO

BACKGROUND: Surgical resection is typically necessary for curative-intent treatment of most solid organ cancers. However, even with meticulous preoperative evaluation, operative procedures are occasionally aborted. The incidence, outcomes, and long-term prognoses of aborted cancer surgery have not been thoroughly investigated. METHODS: All oncologic operations performed at a single tertiary cancer center between 2011-2021 were retrospectively queried; natural language processing of operative reports was used to identify aborted cancer surgeries. Surgical indications, clinicopathologic characteristics, short- and long-term outcomes, and palliative care involvement were retrospectively reviewed from the electronic medical record. RESULTS: Overall, 345 patients underwent aborted cancer surgery for a rate of 36 patients per year. The most common cancers were pancreatic (28%), biliary (14%), and colorectal (9%). The most commonly aborted operations were pancreatoduodenectomy (34%) and hepatectomy (22%). Most operations were aborted due to unanticipated tumor unresectability (47%) and occult metastatic disease (43%). Sixty percent of patients returned to cancer-directed therapy; 9% underwent successful reattempt at resection. The median overall survival of all patients after aborted surgery was 13.6 months (95% confidence interval, 11.2-16.0 months). Those who returned to oncologic therapy had longer survival (18.6 months vs 5.4 months, P < .001). Palliative care consultation was received by 34% and 13% of patients overall and within 30 days of surgery, respectively. CONCLUSION: Aborted cancer surgery was associated with poor outcomes, particularly in patients with aggressive cancer types and those who did not receive further cancer-directed therapy. Future studies should identify interventions such as palliative care consultation that may improve patient-centered outcomes.

RESUMO

Sentinel lymph node mapping in patients with axillary breast carcinoma is technically challenging and poorly described in the literature. We report a patient with primary ectopic breast carcinoma of the axilla in whom concurrent peri-tumoral and intra-tumoral injection of radionuclide tracer allowed for identification and biopsy of sentinel lymph nodes.

RESUMO

Colorectal carcinoma (CRC) is one of the leading causes of cancer-related deaths worldwide, and up to 50% of patients with CRC develop colorectal liver metastases (CRLM). For these patients, surgical resection remains the only opportunity for cure and long-term survival. Over the past few decades, outcomes of patients with metastatic CRC have improved significantly due to advances in systemic therapy, as well as improvements in operative technique and perioperative care. Chemotherapy in the modern era of oxaliplatin- and irinotecan-containing regimens has been augmented by the introduction of targeted biologics and immunotherapeutic agents. The increasing efficacy of contemporary systemic therapies has led to an expansion in the proportion of patients eligible for curative-intent surgery. Consequently, the use of neoadjuvant strategies is becoming progressively more established. For patients with CRLM, the primary advantage of neoadjuvant chemotherapy (NCT) is the potential to down-stage metastatic disease in order to facilitate hepatic resection. On the other hand, the routine use of NCT for patients with resectable metastases remains controversial, especially given the potential risk of inducing chemotherapy-associated liver injury prior to hepatectomy. Current guidelines recommend upfront surgery in patients with initially resectable disease and low operative risk, reserving NCT for patients with borderline resectable or unresectable disease and high operative risk. Patients undergoing NCT require close monitoring for tumor response and conversion of CRLM to resectability. In light of the growing number of treatment options available to patients with metastatic CRC, it is generally agreed that these patients are best served at tertiary centers with an expert multidisciplinary team.

RESUMO

BACKGROUND: We determined the availability and pricing of laboratory testing in the Northern Region of Ghana to identify current gaps with respect to the WHO's Essential Diagnostics List (EDL). METHODS: A representative sample of facilities offering diagnostic testing within the Northern Region was geographically mapped and evaluated, with random sampling stratified by population density. Data were collected on testing menus, volumes, turn-around times, and out-of-pocket test prices. A total of 27 health centers and 39 clinical laboratories were surveyed between June and August 2019. RESULTS: Health centers offered a median of 2 of 20 tests recommended by the WHO for facilities without laboratories. The most common tests offered included point-of-care tests for malaria, HIV, and pregnancy. Clinical laboratories offered a median of 11 of 72 tests on the EDL. These facilities most commonly provided testing for malaria, HIV, pregnancy, HBsAg, urinalysis, HCV Ab, syphilis, glucose, and CBC. Urban laboratories had a total of 36 EDL tests available while rural laboratories had 12. Test prices were higher in private compared to public laboratories. National Health Insurance reimbursements were lower than out-of-pocket prices (38%), and when controlling for test price, test availability was negatively associated with this gap in reimbursement. CONCLUSIONS: Availability of diagnostic testing in Ghana's Northern Region is severely limited compared to the WHO's EDL. The disparity is pronounced in rural facilities. Reimbursement rates should be reset to more closely match out-of-pocket test prices in order to achieve the Universal Health Coverage target of the Sustainable Development Goals.

RESUMO

BACKGROUND: Patients with chronic renal failure (CRF) who are undergoing hemodialysis are at increased risk for infective endocarditis (IE). However, outcomes of surgical treatment for IE in these patients have not been well studied. METHODS: Between 1997 and 2017, 539 patients underwent surgical treatment for IE. Of these patients, 125 were undergoing hemodialysis for end-stage renal disease (ESRD), and 414 had no history of CRF. Primary end points compared in this study were short-term survival and long-term survival. RESULTS: Preoperatively, dialysis-treated patients had higher incidences of diabetes (43% vs 18%), hypertension (79% vs 49%), congestive heart failure (63% vs 48%), cardiogenic shock (13% vs 5.3), and sepsis (29% vs 18%) (all P < .05). Postoperatively, they experienced higher rates of prolonged mechanical ventilation (54% vs 22%), pneumonia (17% vs 5.6%), sepsis (6.4% vs 1.0%), cardiac arrest (7.2% vs 1.7%), gastrointestinal events (14% vs 5.1%), and operative mortality (14% vs 5.8%) (all P < .05). The 5- and 10-year survival rates were significantly worse in the dialysis-treated group at 29% and 16%, respectively, compared with 72% and 53% in the patients who did not have CRF (P < .001). ESRD was a risk factor for both short-term mortality (odds ratio, 2.0) and long-term mortality (hazard ratio, 2.7). Rates of reoperation in dialysis-treated patients were very low: 5- and 10-year incidences were 0% and 2.0%, respectively. CONCLUSIONS: In patients with ESRD and IE, poor postoperative outcomes emphasized the importance of prevention and raised the question whether indications for surgical treatment in the general population are appropriate for patients who are dialysis dependent. Additionally, low rates of reoperation supported the use of bioprosthetic valves in these patients.

RESUMO

Patients with glioma whose tumors carry a mutation in isocitrate dehydrogenase 1 (IDH1R132H) are younger at diagnosis and live longer. IDH1 mutations co-occur with other molecular lesions, such as 1p/19q codeletion, inactivating mutations in the tumor suppressor protein 53 (TP53) gene, and loss-of-function mutations in alpha thalassemia/mental retardation syndrome X-linked gene (ATRX). All adult low-grade gliomas (LGGs) harboring ATRX loss also express the IDH1R132H mutation. The current molecular classification of LGGs is based, partly, on the distribution of these mutations. We developed a genetically engineered mouse model harboring IDH1R132H, TP53 and ATRX inactivating mutations, and activated NRAS G12V. Previously, we established that ATRX deficiency, in the context of wild-type IDH1, induces genomic instability, impairs nonhomologous end-joining DNA repair, and increases sensitivity to DNA-damaging therapies. In this study, using our mouse model and primary patient-derived glioma cultures with IDH1 mutations, we investigated the function of IDH1R132H in the context of TP53 and ATRX loss. We discovered that IDH1R132H expression in the genetic context of ATRX and TP53 gene inactivation (i) increases median survival in the absence of treatment, (ii) enhances DNA damage response (DDR) via epigenetic up-regulation of the ataxia-telangiectasia-mutated (ATM) signaling pathway, and (iii) elicits tumor radioresistance. Accordingly, pharmacological inhibition of ATM or checkpoint kinases 1 and 2, essential kinases in the DDR, restored the tumors' radiosensitivity. Translation of these findings to patients with IDH1132H glioma harboring TP53 and ATRX loss could improve the therapeutic efficacy of radiotherapy and, consequently, patient survival.

RESUMO

BACKGROUND: Spinal metastases pose significant morbidity. For many histologies, the spine is a frequent site for bone metastases. This predilection is not fully understood, and there are conflicting reports regarding the distribution within the vertebral body itself. Knowing this distribution will give clues as to the underlying biologic reason for this increased incidence in the spine and lead to a better understanding of tumor dispersion and growth. METHODS: We retrospectively examined magnetic resonance imaging scans of patients undergoing radiation to the spine from 2015 to 2017 for spinal metastases. The anatomical distribution of lesions was categorized. Lesions were sorted along the sagittal plane into 5 groups: anterior only, anterior + middle, middle only, posterior + middle, and posterior only. Lesions that covered all groups were discarded. χ2 and post-hoc analyses were used for statistical analyses. RESULTS: Three hundred metastatic lesions were examined in 89 patients; 203 lesions were used for analysis. Sixty-five percent of all lesions were found in posterior only and posterior + middle aspects of the vertebral body (P < 0.0001). This localization was significant regardless of histology: lung (67%, P < 0.0001), kidney (66%, P < 0.0001), sarcoma (67%, P < 0.0001), prostate (63%, P = 0.01), and breast (63%, P = 0.01). This was consistent across thoracic (n = 96) and lumbar (n = 63) regions (72% and 64%, respectively, P < 0.0001). CONCLUSIONS: Metastatic lesions of the thoracolumbar spine have a greater propensity to localize to the posterior aspect of the vertebral body. These data support the hypothesis that there may be differences within the vertebral body leading to differential tumor dispersion and growth.
