Comorbidities with non-small cell lung cancer: Is there an interdisciplinary consensus needed to qualify patients for surgical treatment?

INTRODUCTION: Radical surgical treatment is the preferred action for patients with early-stage non-small cell lung cancer (NSCLC). Qualification for surgical treatment should consider a risk associated with the effect of comorbidities on the general condition of the patient. The aim of this article was an attempt to identify the risk factors for postoperative complications in patients treated for NSCLC, with a special focus on the coexisting diseases. METHODS: A total of 400 patients with NSCLC were included in this retrospective study. The incidence of postoperative complications (including major complications according to the European Society of Thoracic Surgeons [ESTS]) was analyzed. Factors associated with high risk of postoperative complications were identified. RESULTS: Postoperative complications occurred in 151 patients (39% operated patients), including severe complications according to ESTS in 75 patients (19%). From univariate analysis, risk factors for postoperative complications were arrhythmias, pneumonectomy, and open thoracotomy. According to ESTS, for major complications, the risk factors included age ≥65 years, the presence of comorbidities, hypertension, and arrhythmias. From multivariate analysis, the risk of complications was higher in patients undergoing pneumonectomy and with cardiac arrhythmias, whereas the risk of serious complications according to ESTS was found in people ≥65 years of age and suffering from comorbidities. CONCLUSIONS: The risk of postoperative complications is affected by both surgical factors and the general health of the patient. Elderly patients with chronic disease history, hypertension, and arrhythmias have an increased risk of postoperative complications. Knowledge of these factors will identify a group of patients requiring internal consultation and optimization of preoperative treatment and postoperative follow-up.

Evaluation of risk factors and assessment models for predicting venous thromboembolism in lung cancer patients.

The aim of the study was to investigate the prognostic significance of selected risk assessment models (RAMs) for predicting venous thromboembolism (VTE) events in patients undergoing outpatient chemotherapy for lung cancer. We evaluated the following VTE-risk assessment tools: Khorana risk score (KRS), PROTECHT score, CONKO score and COMPASS-cancer-associated thrombosis score (COMPASS-CAT). Retrospective analyses were performed on 118 patients with lung cancer, 20 of whom developed VTE with a median of 2.5 months from diagnosis. Patients receiving gemcitabine-based regimen (25%), patients with a history of atrial fibrillation (AF) and patients with chronic kidney disease developed VTE more often than other patients. In the multivariate analysis, high COMPASS-CAT score (OR 8.73; 95% CI 1.01-75.22, P = 0.049), gemcitabine chemotherapy (OR 3.37; 95% CI 1.09-10.39, P = 0.035) and AF (OR 7.19; 95% CI 1.89-27.33, P = 0.004) were all significantly associated with VTE development. VTE occurred in; 13% (n = 2) of the KRS high-risk group, 17.7% (n = 11) of the PROTECHT high-risk group, 15% (n = 4) of the CONKO high-risk group and 23.8% (n = 20) of the COMPASS-CAT high-risk group (n = 84). Only the COMPASS-CAT score was able to identify 100% of patients who developed VTE, and best discriminated between patients with high and low risk of VTE development (C statistic 0.89). The ROC analysis indicated a cutoff value of 11 points (95% CI 0.821-0.962) for COMPASS-CAT for VTE development in patients with lung cancer. In conclusion, in our study of all the VTE-RAMs analyzed, the COMPASS-CAT model was the most accurate predictor of VTE development in patients with lung cancer.

Comorbidity in patients undergoing surgery for lung cancer. Do we have an adequate tool to assess it?

INTRODUCTION: In the recent years comorbidity has been discussed as a factor affecting therapeutic decisions, the course of treatment, and prognosis of patients with lung cancer. The aim of the study was 1. to evaluate the occurrence of comorbidities in patients with lung cancer undergoing surgery, and 2. to investigate the utility of Charlson Comorbidity Index (CCI) and Simplified Comorbidity Score (SCS) for preoperative evaluation of Polish patients with lung cancer. MATERIAL AND METHODS: The retrospective study included 476 patients with lung cancer, who underwent surgical treatment. In all patients, data on histopathological type of the tumor, stage, history of smoking, comorbidities, and spirometric parameters were collected. CCI and SCS scores were calculated. The presence of comorbidities was analyzed in relation to sex, histology, and stage of lung cancer. Correlations between CCI and SCS scores and age, number of pack-years, spirometric parameters were assessed. RESULTS: The most prevalent comorbidities were hypertension (42%), chronic obstructive pulmonary disease (COPD) (22%), coronary heart disease (17%), and diabetes (12%). There were no differences in the distribution of comorbidity depending on the histological type and stage of lung cancer. The CCI and SCS scores showed correlations with age, number of pack-years and spirometric parameters, however, their compounds do not reflect the profile of most prevalent comoribidities. CONCLUSION: The burden of comorbidity among patients with lung cancer is significant. Comorbidity should be assessed while considering patients for surgical treatment. However, the CCI and SCS do not seem precise enough for this purpose.

[Granulomatosis with polyangiitis - clinical picture and review of current treatment options]. / Ziarniniakowatosc z zapaleniem naczyn - obraz kliniczny i przeglad aktualnych opcji terapeutycznych.

Granulomatosis with polyangiitis (GPA) is a rare disease of unknown aetiology, characterized by necrotizing inflammation of small and medium-sized vessels and formation of granulomas. The disease typically involves the upper and lower respiratory tracts and the kidneys, but it can occur in many other locations, often giving a surprising clinical picture. The majority of patients have autoantibodies against cytoplasm of neutrophils (ANCA), of which a pathogenetic role is postulated. The disease affects mostly middle-aged and elderly people, with a predominance of Caucasians. Before the era of immunosuppressive therapy GPA was associated with high early mortality. Nowadays, we have a treatment that gives remission in the majority of patients. The decision about the method of treatment should be made depending on the clinical form of the disease (local or generalized, refractory). Standard remission induction therapy in the generalized disease is cyclophosphamide in combination with steroids. This therapy, however effective, is associated with a number of side effects. In addition, some patients are resistant to standard therapy, and half of them experience relapses. Therefore, there is need for further research for alternative treatment and maintenance therapy. Currently, hopes are raised by biological agents. Among them, the best studied so far is rituximab, which found a place in the current recommendations of EULAR as an alternative drug for patients with refractory disease. The article discusses the clinical picture of GPA, diagnosis and currently recommended treatment.
