An extremely rare primary sarcoma of the lung with peritoneal and small bowel metastases: a case report.

BACKGROUND: Primary sarcoma of the lung is a very rare malignant tumor accounting for less than 0.5% of all lung tumors and presenting diagnostic and treatment challenge. We describe a case of a patient diagnosed with primary lung undifferentiated pleomorphic sarcoma developing subsequent peritoneal and small bowel metastases, which stand for highly unusual disease presentation. CASE PRESENTATION: A 57-year-old male presented with extensive partially necrotic tumor in the left upper lobe (LUL) of the lung that involved LUL bronchus and extended to the visceral pleura. There was no evidence of nodal or visceral dissemination. After initial presentation, the patient was admitted to the hospital's pulmonology department for further workup. The most likely diagnosis based on biopsy specimen was poorly differentiated sarcoma. Left pneumonectomy with mediastinal lymph node dissection was performed. The final pathohistological diagnosis (PHD) was undifferentiated pleomorphic sarcoma (UPS). Three months after lung surgery, a follow-up CT scan was done which showed a 60-mm obstructive metastatic intraabdominal lesion with small bowel infiltration and further separate peritoneal deposits. Unfortunately, an urgent surgery had to be performed as the patient developed signs of acute abdomen due to bowel perforation. Only 2 months later, the patient passed away at home. CONCLUSIONS: Treatment options of UPS are based on algorithms used in treatment of extremity lesions with well-established role of surgery. However, the role of perioperative chemotherapy remains equivocal with no strong evidence-based data due to the rarity of the disease. Small bowel is an unexpected metastatic site, but of significant clinical relevance.

Cancer cachexia, sarcopenia and biochemical markers in patients with advanced non-small cell lung cancer-chemotherapy toxicity and prognostic value.

PURPOSE: Cancer cachexia and sarcopenia are frequently observed in cancer patients and associated with poor survival. The majority of studies of cancer cachexia and sarcopenia have been done in patients with solid tumors of different origins, and there are currently no good predictors of the benefit of chemotherapy or factors that predict survival in advanced cancer. The purpose of our prospective study was to evaluate prevalence of cachexia and sarcopenia using international consensus definition and criteria for diagnosis in patients with diagnosed advanced non-small cell lung cancer (NSCLC) stage IIIB and IV and their relation to chemotherapy toxicity and survival prediction. A secondary aim was to compare several biochemical markers (CRP, IL-6, protein, and albumin) with time to tumor progression in order to assess prognostic value or to guide a treatment. METHODS: Between December 2013 and April 2015, the prospective cohort study of 100 Caucasian patients with advanced NSCLC stage IIIB or IV, who were referred consecutively to Department for Respiratory Diseases "Jordanovac," was evaluated. Anthropometric measurements and biochemical data (CRP, albumin, protein, IL-6, haemoglobin) together with body composition measurements (total muscle cross-sectional area, lumbar skeletal muscle index) were obtained for each patient before starting with platinum-doublet therapy. Skeletal muscle cross-sectional area at the third lumbar vertebra was measured by computerized tomography, and sarcopenia was defined using a previously published cutoff point. Toxicity was assessed after cycle 1 of treatment and time-to-tumor progression was determined prospectively. RESULTS: One hundred patients with advanced lung cancer were recruited: 67 were male and median age was 64 years. The median time to disease progression was 187 days. The prevalence of cachexia and sarcopenia in study cohort was 69 and 47 %, respectively. CRP, IL-6, and albumin concentration in cachectic compared to non-cachectic patients demonstrated statistically significant difference (p = 0.020, p = 0.040, p = 0.003). Cachexia and sarcopenia were not found to be predictors of chemotoxicity nor was time to tumor progression. On the contrary, albumin concentration with established cutoff point of 37.5 g/L was clearly proved as the predictive factor of both chemotoxicity (OR (95 % CI) = 0.85; p < 0.001) and survival (HR (95 % CI) = 0.55). CONCLUSIONS: Albumin level has been shown to be more important predictive marker of chemotherapy toxicity and survival than cachexia and sarcopenia are. This approach in clinical settings can be used to guide the choice of oncologic treatment.

Efficacy and safety of nintedanib and docetaxel in patients with previously treated lung non-squamous non-small cell lung cancer: a multicenter retrospective real-world analysis.

BACKGROUND: The standard first-line systemic treatment for patients with non-oncogene addicted advanced nonsquamous non-small cell lung cancer (NSCLC) is immunotherapy with immune checkpoint inhibitors (ICI) and/or chemotherapy (ChT). Therapy after failing ICI +/- ChT remains an open question, and docetaxel plus nintedanib represent a valid second line option. PATIENTS AND METHODS: A multicenter retrospective trial of real-life treatment patterns and outcomes of patients with advanced lung adenocarcinoma treated with docetaxel plus nintedanib after the failure of ICI and/or ChT was performed. Patients from 2 Slovenian and 1 Croatian oncological center treated between June 2014 and August 2022 were enrolled. We assessed objective response (ORR), disease control rate (DCR), median progression free survival (PFS), median overall survival (OS), and safety profile of treatment. RESULTS: There were 96 patients included in the analysis, with ORR of 18.8%, DCR of 57.3%, median PFS of 3.0 months (95% CI: 3.0-5.0 months), and a median OS of 8.0 months (95% CI: 7.0-10.0 months). The majority of patients (n = 47,49%) received docetaxel plus nintedanib as third-line therapy. The ORR for this subset of patients was 19.1%, with a DCR of 57.4%. The highest response rate was observed in patients who received second-line docetaxel plus nintedanib after first-line combination of ChT-ICI therapy (n = 24), with an ORR of 29.2% and DCR of 66.7% and median PFS of 4.0 months (95% CI: 3.0-8.0 months). Fifty-three patients (55.2%) experienced adverse events (AEs), most frequently gastrointestinal; diarrhea (n = 29, 30.2%), and increased liver enzyme levels (n = 17, 17.7%). CONCLUSIONS: The combination of docetaxel and nintedanib can be considered an effective therapy option with an acceptable toxicity profile for patients with advanced NSCLC after the failure of ICI +/- ChT.

Croatian National Cancer Patient Experience Survey.

BACKGROUND: Cancer patients' experiences of the healthcare system, care, and treatment are increasingly viewed as important in order to inform and improve quality of care, patient safety, and treatment efficacy. Understanding patient experience is a key step in moving toward patient-centred care. The aims of this study were to determine the experience of cancer patients in Central and Eastern European countries and to identify the needs and perspectives of oncological patients during the cancer treatment. In this paper, results from Croatia are presented. METHODS: A sixty-nine item online survey was translated by native-language participating countries. Only registered members (subjects with confirmed cancer diagnosis) of the national patient oncology associations in each participating country were allowed to access and complete the online questionnaire (n = 16,458). Data were collected between October 2018 to February 2019. The Croatian Coalition of Health Associations enabled the authors of this paper to use the collected data from a sample of the Croatian participants (n = 2460) for the purposes of publication. RESULTS: Two-thirds (67.3%) of the respondents reported satisfaction with the length of time needed for getting tests done. Bad news was delivered sensitively to 52.97% of the participants, and 52.76% received a cancer treatment plan. During the hospitalisation, 45.93% responded that they did not find someone from the hospital staff whom they could talk to about their worries and fears, and 57.48% were not given any contact information in case of concerns about their condition or treatment following the discharge. Regarding the patients' preferences, needs, and values, 60.81% of the respondents felt that the greatest improvement would be to perform all services in one place, and 55.28% felt that improvement would be achieved through a multidisciplinary team coordinated by one person. CONCLUSIONS: The study reveals domains that need to be addressed in the overall Croatian healthcare system for oncology patients. Based on the obtained data, we can conclude that there is a large need for improvement in patient experience on the oncology pathway.

[Clinical recommendations for diagnosing, treatment and monitoring patients with non-small cell lung cancer]. / Klinicke upute za dijagnozu, lijecenje i pracenje bolesnika oboljelih od karcinoma pluca nemalih stanica.

In Croatia, lung cancer is the most common malignant disease among male population and the third common among female population where 85% of patients have non-small cell lung cancer. Due to significance of this disease it is necessary to define and implement standardized approach for diagnostic and treatment algorithm as well to patients monitoring. Several multidisciplinary sessions were organized in achieving this goal. The sessions' results are given in the form of the Clinical guidelines.

Pulmonary hypertension in patient with elevated homocystein level and blast injuries.

38-year-old man had chronic deep venous thrombosis (DVT) as a result of multiple injuries caused by an explosion of grenade 12 years ago, with recurrent pulmonary thromboembolisms and pulmonary hypertension which was unrecognized for a decade. Patient was admitted with a progressive dyspnea and exercise intolerance (NYHA II). The diagnosis was established according to clinical symptoms, transthoracic echocardiography, phlebography, lung scintigraphy and pulmonary angiography. Oral anticoagulant therapy was introduced and cava filter indicated to implant. During phlebography a floating thrombus was found in the inferior cava vein underneath renal vein. Implantation was delayed and patient received systemic fibrinolytic therapy with streptokinase (7500 000 UI within 4 days), followed by heparin infusion and warfarin. Post-fibrinolytic phlebography showed clear lumen of inferior vena cava. Fibrinolysis had also affected pulmonary hypertension-systolic pressure in the right ventricle measured by Doppler echocardiography decreased from 90 to 65 mmHg. Permanent intravenous cava filter was implanted.

Efficacy and safety of budesonide/formeterol combination therapy in asthma patients.

Budesonide/formoterol as single inhaler was developed for treating asthma patients who are not adequately controlled on glucocorticoides alone. The aim of this study was to evaluate efficacy, safety and patient/physician satisfaction of budesonide/formoterol therapy.Total of 268 asthma patients (120 men, mean age 38.8 +/- 37.2 years, and 148 women, mean age 42.2 +/- 32 years) were included in the study. All patients received budesonide/formoterol bid (640 mcg of budesonide and 18 mcg of formoterol daily) during run-in period for three weeks. Patients were followed during 14 weeks at 5 visits. At each visit lung function (FEV1 and PEF) was measured,presence of side affects was recorded and questionnaire was given to patients and physicians to estimate the level of satisfaction with budesonide/formoterol therapy (1 very unsatisfied to 5 very satisfied). Significant improvement was noticed in FEV1, from 76.25% of predicted value to 86.94% (p < 0.01); and in PEF from 380.84 L/min to 442.29 L/min (p < 0.01) in all patients. At the end of the study patients' satisfaction with budesonide/formeterol therapy was significantly improved comparing with satisfaction with previously taken therapy, in average grade, from 2.94 to 4.56 (p < 0.01), and similar results were noticed with physicians' satisfaction, from 2.60 to 4.41 (p < 0.01). Budesonide/formoterol in single inhaler, significantly improved lung function in patients with asthma.

Recombinant factor VIIa in massive haemoptysis associated with chronic necrotising aspergillosis.

The successful use of recombinant activated factor VII (rFVIIa), in treating massive, life-threatening haemoptysis in a 55-year-old male patient with chronic necrotising aspergillosis, is reported. Patient diagnosed with chronic necrotising aspergillosis three months ago was admitted to our department with massive haemoptysis. Patient was treated as outpatient with itraconazole. One day post-admission, two doses of rFVIIa (30 microg x kg(-1)) were administered and the haemoptysis was successfully resolved. Two further doses of rFVIIa (30 microg x kg(-1) were given the following day, and after that there were no more recurrences of pulmonary haemorrhage. No thromboembolic or other adverse events were observed following rFVIIa therapy. Our findings suggest that use of rFVIIa may represent a safe and effective treatment choice for patients with haemoptysis due to aspergillosis.

[Erlotinib in non-small cell lung cancer: experience of clinical hospital for lung diseases Jordanovac]. / Erlotinib u lijecenju bolesnika s uznapredovalim karcinomom pluca nemalih stanica: iskustvo klinicke bolnice za plucne bolesti "Jordanovac".

Treatment with erlotinib, an inhibitor of the epidermal growth factor receptors, has significantly improved the overall survival rate and quality of life in patients with non-small cell lung cancer who had failed the standard first- or second-line chemotherapy. In Clinical hospital for lung diseases "Jordanovac" a total of 36 patients were treated with erlotinib. The response rate was as follows: in four patients (11%) complete response was achieved, in five (4%) partial response, while fourteen patients (39%) had stable disease. Hence, the evident clinical benefit of treatment with erlotinib was registered in 23 patients (64%) altogether. The treatment was well tolerated and it was not associated with significant toxicity. Our results confirm the antitumour efficacy of erlotinib and show a clear treatment benefit for patients with non-small cell lung cancer in our country.

Correlation Between Occurrence and Deterioration of Respiratory Diseases and Air Pollution Within the Legally Permissible Limits.

The aim of the study was to investigate the unknown effect of air pollutants on the occurrence or deterioration of respiratory diseases in the area with a humid continental climate. This retrospective study included 5868 patients with respiratory symptomatology (upper respiratory tract infection (URTI), pneumonia, acute bronchitis, chronic obstructive pulmonary disease (COPD), and asthma) admitted to emergency department (ED). The number of patients, values of meteorological parameters (mean daily values of air temperature pressure and relative humidity) and concentrations of air pollution particles (≤10 µm (PM10), ozone (O3) and nitrogen dioxide (NO2)) were collected during a two-year ( July 2008 - June 2010) period. There were 1839 (31.3%), 1712 (29.2%), 1313 (22.4%), 614 (10.5%) and 390 (6.6%) patients with pneumonia, COPD, URTI, acute bronchitis and asthma, respectively. The mean daily concentrations of NO2 (25.9 (1.7-89.7) µg/m3), O3 (47.1 (4.7-135.4) µg/m3) and PM10 particles (25.7 (4.6-146.6) µg/m3) were below the legally defined thresholds. Among other results, the occurrence of respiratory diseases showed positive Spearman's correlation with the values of air humidity (days 0-3, r=0.15 to 0.19), PM10(days 0-3, r=0.10 to 0.13) and NO2 concentrations (day 0, r=0.11), and negative correlation with the values of air temperature (days 0-3, r=-0.36 to -0.34), pressure (day 0, r=-0.10) and O3 concentrations (days 0-3, r=-0.21 to -0.22) (p<0.05 all). In conclusion, the occurrence of respiratory diseases showed correlation with weather conditions and air pollutants despite the legally permitted values in the region with a humid continental climate.

Color Doppler ultrasonography is reliable in assessing the risk of esophageal variceal bleeding in patients with liver cirrhosis.

PURPOSE: The aim of the study was to examine the role of Doppler ultrasonography of the portal vein in predicting esophageal variceal bleeding in patients with liver cirrhosis and portal hypertension by comparing the ultrasound data to the endoscopic findings. PATIENTS AND METHODS: 99 patients with liver cirrhosis and esophageal varices underwent color Doppler ultrasonography and esophagogastroduodenoscopy. The following portal hemodynamic parameters were analyzed: diameter and cross-sectional area, mean blood flow velocity, blood flow volume, perfusion pressure gradient, congestion index, and platelet count-to-spleen diameter ratio. Variceal characteristics, the size and the presence of red signs, were determined by endoscopic examination. RESULTS: Patients with variceal red signs had significantly higher values of portal diameter (1.538 +/- 0.246 vs. 1.243 +/- 0.167), cross-sectional area (1.286 +/- 0.448 vs. 0.945 +/- 0.256), blood flow volume (965.520 +/- 432.728 vs. 625.117 +/- 320.999) and congestion index (0.165 +/- 0.068 vs. 0.126 +/- 0.051) than patients without red signs, while the perfusion pressure gradient (0.260 +/- 0.087 vs. 0.447 +/- 0.271) and the platelet-to-spleen ratio (522.424 +/- 222.823 vs. 708.921 +/- 230.769) were lower. The same pattern of differences between the ultrasound parameters was found in patients with large varices comparing ones with red signs to the ones without them (diameter, 1.567 +/- 0.234 vs. 1.258 +/- 0.175; cross-section, 1.313 +/- 0.455 vs. 1.061 +/- 0.264; flow volume, 988.195 +/- 443.353 vs. 739.423 +/- 414.281; congestion index, 0.171 +/- 0.067 vs. 0.130 +/- 0.058; perfusion pressure gradient 0.247 +/- 0.078 vs. 0.501 +/- 0.379 and platelet-to-spleen ratio 479.930 +/- 184.302 vs. 699.094 +/- 316.171). Differences in values of ultrasonographic parameters were less obvious among groups of patients with different variceal sizes: only the diameter, cross-sectional area and blood flow volume were significantly different. The mean blood flow velocity did not depend on the variceal size or on the presence of red signs. The sensitivities and specificities of the analyzed parameters were 60-80% and 48.6-78.4%, respectively. CONCLUSIONS: Results suggest that color Doppler ultrasonography is a useful noninvasive method for evaluating the risk of esophageal variceal bleeding in patients with liver cirrhosis.
