Acute Thoracic Findings in Oncologic Patients

CT of the esophagus in the ER: what you need to know and what you need to remember

Computed tomography (CT) imaging is a crucial diagnostic tool in the emergency department (ED) for evaluating non-traumatic esophageal conditions. Advanced imaging techniques such as multidetector CT (MDCT) quickly provide detailed 3D images with high spatial resolution, making it ideal for rapid assessment of a variety of esophageal pathologies. This pictorial essay presents 10 illustrative cases to highlight the clinical applications of MDCT and its critical role in diagnosing conditions like perforation, foreign body impaction, inflammatory or infectious esophagitis, achalasia, fistulae, and neoplasms. Optimized CT protocols, such as contrast-enhanced imaging and advanced postprocessing techniques like maximum intensity projection (MIP) images and volumetric rendering technique (VRT), in addition to 3D cinematic rendering, are crucial in improving diagnostic accuracy and enhancing visualization of anatomical structures. The cases presented emphasize the importance of early detection and timely management of esophageal conditions, as small delays can lead to significantly increased morbidity and mortality. Ultimately, a multidisciplinary approach that coordinates clinical, radiological, and pathological evaluations ensures appropriate management and improved patient outcomes in esophageal emergencies.

Side Effects of Oncologic Treatment in the Chest: Manifestations at FDG PET/CT

Fluorodeoxyglucose (FDG) PET/CT is a vital imaging technique used for staging, assessing treatment response, and restaging following completion of therapy in patients who are undergoing or have completed oncologic treatment. A variety of adverse effects from chemotherapy, targeted therapy, immunotherapy, and radiation therapy are commonly encountered in oncologic patients. It is important to be aware of the manifestations of these adverse effects seen on FDG PET/CT images to avoid misinterpreting these findings as disease progression. Furthermore, early identification of these complications is important, as it may significantly affect patient management and even lead to a change in treatment strategy. The authors focus on the FDG PET/CT manifestations of a broad spectrum of oncologic therapy-related adverse effects in the thorax, as well as some treatment-related changes that may potentially mimic malignancy.

Chest CT accuracy in the diagnosis of SARS-CoV-2 infection: initial experience in a cancer center

OBJECTIVE

To evaluate the accuracy of chest computed tomography (CT) in patients with suspected severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) infection at a cancer center.

MATERIALS AND METHODS

This retrospective single-center study selected 91 patients who had chest CT and real-time polymerase chain reaction (RT-PCR) test collected at the same day. CT results were classified in negative, typical, indeterminate or atypical findings. Diagnostic accuracy, sensitivity and specificity were calculated for two different scenarios: in the first, only typical findings on CT were considered positive; in the second, both typical and indeterminate findings were considered positive.

RESULTS

Mean patients' age was 58.2 years, most were male (60.4%) and had prior diagnosis of cancer (85.7%). CT showed typical findings in 28.6%, indeterminate findings in 24.2% and atypical findings in 26.4%. RT-PCR results were positive for SARS-CoV-2 in 27.5%. The sensitivity, specificity and accuracy in the first and second scenarios were respectively 64.0%, 84.8% and 79.1%, and 92.0%, 62.1% and 70.3%.

CONCLUSION

CT has a high accuracy for the diagnosis of SARS-CoV-2 infection. Different interpretation criteria can provide either high sensitivity or high specificity. CT should be integrated as a triage test in resource-constrained environments during the pandemic to assist in the optimization of PCR-tests, isolation beds and intensive care units.

Phase III study of tri-modality combination therapy with induction docetaxel plus cisplatin and 5-fluorouracil versus definitive chemoradiotherapy for locally advanced unresectable squamous-cell carcinoma of the thoracic esophagus (JCOG1510: TRIANgLE)

A randomized phase III trial commenced in Japan in February 2018. Definitive chemoradiotherapy (CRT) with cisplatin plus 5-fluorouracil is the current standard treatment for locally advanced unresectable esophageal carcinoma. The purpose of this study is to confirm the superiority of induction chemotherapy with docetaxel plus cisplatin and 5-fluorouracil (DCF) followed by conversion surgery or definitive CRT over definitive CRT alone for overall survival (OS) in patients with locally advanced unresectable squamous-cell carcinoma of thoracic esophagus. A total of 230 patients will be accrued from 47 Japanese institutions over 4.5 years. The primary endpoint is OS, and the secondary endpoints are progression-free survival, complete response rate of CRT, response rate of DCF, adverse events of DCF and CRT, late adverse events and surgical complications. This trial has been registered at the Japan Registry of Clinical Trials as jRCTs031180181.

Adaptation of the Nursing Activities Score for oncologic care

OBJECTIVE

To adapt the contents of the Nursing Activities Score (NAS) tool to assist patients with cancer.

METHOD

Methodological research that according to the Delphi Technique is a method aiming at the validation of content through agreement of experts.

RESULTS

It took two rounds of opinion of experts, which added content contributions without modifying the structure and score of the original tool. The level of agreement ranged from 71 to 86%, and biological factors and assistance were more suggested: Monitoring and controls; Laboratory investigations; Support and care for family members and patients; Intravenous replacement; Renal support; Management activities.

CONCLUSION

A high level of complexity of patients with cancer, and the demand for care and biopsychosocial-spiritual care was diagnosed. This tool will enable the measurement of the workload of the Oncology Nursing team, which can contribute to the staffing dimensioning.

Imaging of Oncologic Emergencies

Oncologic emergencies can be either the result of the primary tumor, its metastasis, a paraneoplastic syndrome or reaction to the chemotherapy. Imaging plays a crucial role in ensuring a prompt diagnosis as well as assisting in the therapeutic management. In this article, we discuss the common thoracic and abdominal oncological emergencies that may be encountered in an emergency department.

Vascular spinal cord obstruction associated with superior vena cava syndrome: A case report and literature review

RATIONALE

Superior vena cava syndrome (SVCS) is the obstruction of blood flow through the SVC, causing complete or partial blockade of the collateral circulation of returning venous blood. SVCS is frequently presented with facial, neck, trunk, and upper limbs swelling and so on. However, to the best of our knowledge, the obstruction of the venous return in the spinal veins is rarely a manifestation of SVCS.

PATIENT CONCERNS

We presented a rare case of a 52-year-old male patient with 2-month history of progressive right upper limb numbness and swelling and 10-day history of extremities malfunctioning. Cervical magnetic resonance imaging (MRI) detected obstruction of the spinal venous return. Lung computed tomography (CT) revealed lesions in the esophagus, which indicated esophageal cancer with mediastinal lymph nodes metastasis and signified SVCS.

DIAGNOSES

With the results of laboratory findings, cervical MRI, lung CT findings, and physical examination, the patient was diagnosed with SVCS manifesting as spinal vein obstruction.

INTERVENTIONS AND OUTCOMES

The family abandoned further treatment, and the patient passed away 2 months after discharge.

LESSONS

The case indicates that SVCS can induce systemic and spinal cord diseases affecting the venous return. Further studies are necessary to reveal the mechanism for SVCS inducing spinal veins obstruction and to explore whether SVCS patients with and without vascular spinal cord obstruction have different prognoses.

Management of superior vena cava syndrome in critically ill cancer patients

PURPOSE

The purpose of this study is to describe the management and outcome of critically ill cancer patients with Superior Vena Cava Syndrome (SVCS).

METHODS

All cancer patients admitted to the medical intensive care unit (ICU) of the Saint-Louis University Hospital for a SVCS between January 2004 and December 2016 were included.

RESULTS

Of the 50 patients included in the study, obstruction of the superior vena cava was partial in two-thirds of the cases and complete in one-third. Pleural effusion was reported in two-thirds of the patients, pulmonary atelectasis in 16 (32%), and pulmonary embolism in five (10%). Computed tomography of the chest showed upper airway compression in 18 (36%) cases, while echocardiography revealed 22 (44%) pericardial effusions. The causes of SVCS were diagnosed one (0-3) day after ICU admission, using interventional radiology procedures in 70% of the cases. Thirty (60%) patients had hematological malignancies, and 20 (40%) had solid tumors. Fifteen (30%) patients required invasive mechanical ventilation, seven (14%) received vasopressors, and renal replacement therapy was implemented in three (6%). ICU, in-hospital, and 6-month mortality rates were 20, 26, and 48%, respectively. The cause of SVCS was the only factor independently associated with day 180 mortality by multivariate analysis. Patients with hematological malignancies had a lower mortality than those with solid tumors (27 versus 80%) (odds ratio 0.12, 95% confidence interval (0.02-0.60), p < 0.01).

CONCLUSION

Airway obstruction and pleural and pericardial effusions contributed to the unstable condition of cancer patients with SVCS. The vital prognosis of SVCS was mainly related to the underlying diagnosis.

Placement of transnasal drainage catheter and covered esophageal stent for the treatment of perforated esophageal carcinoma with mediastinal abscess

BACKGROUND AND OBJECTIVES

Perforated esophageal carcinoma with mediastinal abscess is a clinically life-threatening emergency. Herein, we summarize our experience with placement of transnasal drainage catheters and covered esophageal stents for the treatment of this condition.

METHODS

We retrospectively assessed the medical records of 20 patients who were treated using our intervention protocol. Patients received local anesthesia and sedation prior to transnasal drainage catheter placement into the mediastinal abscess, which was followed by esophageal stent placement. Once the fluid was completely drained and the abscess was completely closed, the drainage catheter was removed.

RESULTS

The placement of the drainage catheter and stent was successful in all patients. The drainage catheter was successfully removed from the mediastinum after 7-60 days in 14 patients. During the follow-up of 1-18 months, six patients died from hemorrhage, eight from cancer progression or pulmonary infection, one from atrial fibrillation, and one from asphyxia caused by tracheal compression. The remaining four patients can eat normally.

CONCLUSIONS

Placement of transnasal drainage catheters and covered esophageal stents may be an appropriate palliative therapy for patients with perforated esophageal carcinoma with mediastinal abscess who are not candidates for surgery or have a high postoperative risk.
