RESUMO

(1) Background: Computed tomography (CT) plays a paramount role in the characterization and follow-up of COVID-19. Several score systems have been implemented to properly assess the lung parenchyma involved in patients suffering from SARS-CoV-2 infection, such as the visual quantitative assessment score (VQAS) and software-based quantitative assessment score (SBQAS) to help in managing patients with SARS-CoV-2 infection. This study aims to investigate and compare the diagnostic accuracy of the VQAS and SBQAS with two different types of software based on artificial intelligence (AI) in patients affected by SARS-CoV-2. (2) Methods: This is a retrospective study; a total of 90 patients were enrolled with the following criteria: patients' age more than 18 years old, positive test for COVID-19 and unenhanced chest CT scan obtained between March and June 2021. The VQAS was independently assessed, and the SBQAS was performed with two different artificial intelligence-driven software programs (Icolung and CT-COPD). The Intraclass Correlation Coefficient (ICC) statistical index and Bland-Altman Plot were employed. (3) Results: The agreement scores between radiologists (R1 and R2) for the VQAS of the lung parenchyma involved in the CT images were good (ICC = 0.871). The agreement score between the two software types for the SBQAS was moderate (ICC = 0.584). The accordance between Icolung and the median of the visual evaluations (Median R1-R2) was good (ICC = 0.885). The correspondence between CT-COPD and the median of the VQAS (Median R1-R2) was moderate (ICC = 0.622). (4) Conclusions: This study showed moderate and good agreement upon the VQAS and the SBQAS; enhancing this approach as a valuable tool to manage COVID-19 patients and the combination of AI tools with physician expertise can lead to the most accurate diagnosis and treatment plans for patients.

RESUMO

Aorto-enteric fistulas are serious complications of aortic surgery that require swift, effective surgical intervention. We report a case of a secondary aortoenteric fistula treated with prosthesis replacement and an intestinal suture subsequently complicated by the dehiscence of the previously constructed anastomosis. We opted for reconstruction re-intervention, closing the intestinal lesion by means of a mechanical suture above the jejunal dehiscence, making a side-to-end jejuno-jejunal Roux anastomosis and an end-to-side anastomosis at the base of the loop. The operation was completed by performing a gastrostomy and transforming the fistula into a jejunostomy. This intervention enabled us to discharge the patient in good general condition after 30 days.

RESUMO

BACKGROUND: Gemcitabine has been widely studied in elderly patients affected by advanced non-small cell lung cancer (NSCLC). A prolonged constant infusion (10 mg/m2/min) has been proposed as a way to improve its efficacy. Aim of this study is to describe activity and toxicity of single-agent gemcitabine given as prolonged infusion in the treatment of elderly patients with advanced NSCLC. PATIENTS AND METHODS: Patients aged 70 years or older, with stage IV or IIIB (effusion/supraclavicular nodes) NSCLC, good performance status (0 or 1 according to ECOG classification) who had never received chemotherapy were eligible. Gemcitabine was administered at the dose of 1200 mg/m2 by prolonged infusion (10 mg/m2/min) on days 1 and 8 of each cycle. Courses were repeated every 21 days, for a maximum of 6 cycles, unless disease progression or severe toxicity. A single stage phase 2 design was applied, with 51 patients required to estimate a 25% +/- 10% response rate. Ten responses were required to define the treatment as active. RESULTS: Fifty-one patients were enrolled, with a median age of 76 years (range 70-83). Two complete responses and seven partial responses were observed, for an overall response rate of 17.6% (95% exact C.I.: 8.4-30.9%). The median time to disease progression was 16.1 weeks (95% C.I.: 11.1-20.6) and the median overall survival was 41.3 weeks (95% C.I.: 27.6-50.6). There were 2 toxic deaths, due to bleeding and liver toxicity, and one patient had an ischemic stroke. Other non-haematological toxicities were: fatigue (44% of patients), grade 2-3 pulmonary toxicity (8%), grade 2-3 hepatic toxicity (16%). Nausea and stomatitis were mild and no cases of cardiac toxicity were observed. Haematological toxicity was mild, with no case of febrile neutropenia. CONCLUSION: Gemcitabine at prolonged constant infusion produced a response rate lower than that required by study design and should no longer be of interest for the treatment of elderly patients with advanced NSCLC.

RESUMO

PURPOSE: To study the prognostic value for overall survival of baseline assessment of functional status, comorbidity, and quality of life (QoL) in elderly patients with advanced non-small-cell lung cancer treated with chemotherapy. PATIENTS AND METHODS: Data from 566 patients enrolled onto the phase III randomized Multicenter Italian Lung Cancer in the Elderly Study (MILES) study were analyzed. Functional status was measured as activities of daily living (ADL) and instrumental ADL (IADL). The presence of comorbidity was assessed with a checklist of 33 items; items 29 and 30 of the European Organisation for Research and Treatment of Cancer (EORTC) core questionnaire QLQ-C30 (EORTC QLQ-C30) were used to estimate QoL. ADL was dichotomized as none versus one or more dependency. For IADL and QoL, three categories were defined using first and third quartiles as cut points. Comorbidity was summarized using the Charlson scale. Analysis was performed by Cox model, and stratified by treatment arm. RESULTS: Better values of baseline QoL (P = .0003) and IADL (P = .04) were significantly associated with better prognosis, whereas ADL (P = .44) and Charlson score (P = .66) had no prognostic value. Performance status 2 (P = .006) and a higher number of metastatic sites (P = .02) also predicted shorter overall survival. CONCLUSIONS: Pretreatment global QoL and IADL scores, but not ADL and comorbidity, have significant prognostic value for survival of elderly patients with advanced non-small-cell lung cancer who were treated with chemotherapy. Using these scores in clinical practice might improve prognostic prediction for treatment planning.

RESUMO

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment. Supportive care data were available for 1185 out of 1312 (90%) enrolled patients. Gastrointestinal drugs (45.7%), corticosteroids (33.4%) and analgesics (23.8%) were the most frequently observed categories. The mean number of drugs per patient was 2.43; 538 patients (45.4%) assumed three or more supportive drugs. Vinorelbine does not produce substantial variations in the SC pattern, while cisplatin-based treatment requires an overall higher number of supportive drugs, with higher use of antiemetics (41 vs 27%) and antianaemics (10 vs 4%). Patients with worse PS are more exposed to corticosteroids (42 vs 30%). Elderly patients require drugs against concomitant diseases significantly more than adults (20 vs 7%) and are less frequently exposed to antiemetics (12 vs 27%). In conclusion, polypharmacotherapy is a relevant issue in patients with advanced NSCLC. Chemotherapy does not remarkably affect the pattern of SC, except for some drugs against side effects. Elderly patients assume more drugs for concomitant diseases and receive less antiemetics than adults.
