RESUMO
BACKGROUND: The severity and prognosis of an array of inflammatory diseases have been predicted using systemic inflammatory indices, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio, lymphocyte-to-monocyte ratio (LMR), derived neutrophil-to-lymphocyte ratio (dNLR), and systemic immune inflammation index (SII). The purpose of this study was to examine the association between systemic inflammatory markers and postoperative arrhythmias (PA) in esophageal cancer patients. METHODS: In the study, laboratory-related parameters were gathered and examined in 278 patients (non-PA = 221, PA = 57). Fit separate propensity score matching (PSM) within subgroup strata (surgery approaches); match within strata, and aggregate for main analysis. Finally, we established a 1:1(57:57) model. The ability of inflammatory makers on the first post-esophagectomy day to distinguish PA from postoperative non-arrhythmia (non-PA) by receiver operating characteristic (ROC) analysis. RESULTS: On the first post-esophagectomy day, there was a greater difference between PA and non-PA in terms of white blood cell (WBC) and neutrophil (NE), Neutrophil percentage (NE%), NLR, dNLR, LMR, and SII. After PSM, the following variables were substantially different between non-PA and PA: NE%, NLR, dNLR, and SII. It was found that WBC, NE, NE%, NLR, dNLR, LMR, and SII had the area under the curve (AUC) that was higher than 0.500 in ROC analysis, with NLR and SII having the highest AUC (AUC = 0.661). The indicators were subjected to binary logistic regression analysis, which increased the indicators' predictive ability (AUC = 0.707, sensitivity = 0.877). CONCLUSION: On the first post-esophagectomy day, systemic inflammatory indicators were significantly correlated with both PA and non-PA, and high SII and NLR are reliable markers of PA.

Background: Malignant melanoma is a malignant tumor of melanocytes. All body organs can be invaded by it; however, the skin is the most common site of invasion. Melanomas involving the lungs are almost always metastatic and it is extremely rare to find a true primary malignant melanoma of the lung (PMML). Compared to cutaneous melanoma, mucosal melanoma has a different biology and clinical appearance. Since there are no standards for the diagnosis and treatment of PMML, it is treated differently. We reported a patient with PMML underwent surgery after programmed cell death 1 (PD-1) immunotherapy. Case Description: A 62-year-old female patient presented with an occupying lesion in the right upper lung lobe found on physical examination. A computed tomography (CT) scan was done, and the results showed a lobulated soft tissue mass shadow of roughly 54 mm × 50 mm in the upper lobe of the right lung. The histological results of a CT-guided percutaneous lung biopsy were consistent with malignant melanoma. She was identified as having primary melanoma of the lung after undergoing a full physical examination to rule out occult primary tumor metastases. The patient received a total of 33 cycles of immunotherapy (PD-1). We did a right upper lung lobectomy after shrinking the melanoma in the right lung's upper lobe to a size of 16 mm × 10 mm. After the operation, the patient was monitored for 6 months and made a full recovery without recurrence. Conclusions: The preoperative immune system in combination with a surgical procedure may boost patients' chances of survival. These findings need to be confirmed in more clinical research.
