The aim of the study was to determine the prognostic significance of PLR and NLR ratios in patients operated due to non-small cell lung cancer. Material:The study group consisted of 532 (174 women, 358 men) patients with non-small cell lung cancer (NSCLC) staged IA-IIIA. The mean age was 63.6 years (range 36 to 84 years). Together with platelet/lymphocyte ratio (PLR) and neutrophil/lymphocyte ratio (NLR), the following factors were included in the statistical analysis: age, sex, smoking history, the number of leukocytes, neutrophils, and platelets, histopathology, T-stage, N-stage, concomitant diseases according to the Charlson Comorbidity Index (CCI), type of operation, adjuvant chemotherapy, and overall survival. Results: Univariate analysis showed an association between the value of PLR and NLR and the length of survival. Multivariate analysis found that the stage of advancement of the neoplastic disease (p=0.00003), adjuvant chemotherapy (p=0.009), CCI > 4 (0.00008), and PLR > 144 (p=0.001) were negative prognostic factors for survival > 2 years; however, this effect diminishes in patients surviving more than 5 years. Conclusion: PLR might serve as a prognostic factor in patients affected by NSCLC with expected two-year overall survival.

Background: The aim of the study was to determine a survival prognostic value of selected blood morphological rates of patients, operated on due to non-small cell lung cancer (NSCLC). Methods: The study was conducted on 532 patients, surgically treated due to NSCLC, in stages IA-IIIA, 174 females and 358 males, mean age 63.6 years (36-84 years) were included in the study. Blood parameters and clinical factors were included in statistical analysis, in order to determine potential prognostic values of red blood cell distribution width-standard deviation (RDW-SD), mean corpuscular volume (MCV) of red cell and hemoglobin. Factors contained: age, sex, smoking history, histopathological diagnosis , T category, N category, age-adjusted Charlson Comorbidity Index (CCI), number of lymphocytes, neutrophils, monocytes, platelets, the neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR), kind of surgery, patient survival. Results:The univariate analysis revealed a dependence of the value of RDW-SD and CCI values, the number of monocytes, NLR and PLR values, neoplasia stage and the overall survival. The multivariate analysis confirmed that not only N2 category and the value of CCI above 4 are negative prognostication factors, but also RDW-SD above 43 fL (P=0.00007) and PLR above 138 (P=0.001) are such negative factors of survival prognosis. Conclusions: RDW-SD is an independent and significant prognostic factor of patients' survival operated on due to NSCLC.

IntroductionThe indications for videothoracoscopy are very broad and include the treatment of mediastinal tumours.AimTo present our experience of using the minimally invasive technique in treating benign neurogenic tumours.Material and methodsTwenty-two patients were treated due to tumours of the posterior mediastinum from 2003 to 2012. The size of the tumours ranged from 2 cm to 25 cm. Tumours up to the size of 6 cm were treated using videothoracoscopy (VT), bigger ones through thoracotomy.ResultsThe videothoracoscopy technique was used in 17 patients, thoracotomy in 5. In 2 cases conversion was required due to adhesions in the pleural cavity preventing VT treatment. Complications related to the procedure were not observed. The average time of hospital stay after VT treatment was 4 days, while after thoracotomy it was 6 days. Histologically, tumours of benign nature were found in all cases. Schwannoma was diagnosed in 15 patients, ganglioneuroma in 3 patients, neurofibroma in 3 patients, and chemodectoma in 1 patient. None of the 3 cases of neurofibroma was associated with Recklinghausen's disease. At a mean follow-up of 60 months no recurrence of the tumour was found.ConclusionsIn the case of tumours up to 6 cm the best surgical technique is videothoracoscopy. In the case of large tumours the best access is the open technique. The minimally invasive technique allows one to shorten the patient's treatment time, reduce postoperative pain and obtain a good cosmetic effect of the treatment.

IntroductionOver 80% of patients with esophageal cancer are qualified only for palliative treatment. The main goal of the therapy is to eliminate symptoms of dysphagia.AimTo analyze complications after insertion of prostheses and stents in patients with inoperable cancer of the esophagus/cardia.Material and methodsFrom 1996 to 2015 prostheses of the esophagus were implanted in 1309 patients. In the strictures of the lower part of the esophagus, Barbin-Mousseau prostheses (102 cases) and Häring prostheses (324 cases) were placed. In the strictures of the upper and middle part of the esophagus, Wilson-Cook prostheses (65 cases) and Sumi prostheses (51 cases) were implanted using rigid oesophagoscopy. Since 2001, 867 esophageal stents have been implanted.ResultsComplications occurred in 146 (11%) patients, including 7 (0.6%) cases of death. The most common complication was the recurrence of swallowing disorders (74 patients). In 51 patients, tumor overgrowth over the stent/prosthesis was responsible for that symptom, and in 23 patients its clogging. A fistula (22 cases) and the passage of the prosthesis/stent (25 cases) were the second most common group of complications. Compression of the trachea, bleeding, and dehiscence of wounds occurred in a total of 18 patients. Complications were mostly treated through the repositioning of the prosthesis/stent or the insertion of an additional one.ConclusionsThe most common complications after esophageal prosthetics are the recurrence of dysphagia, a fistula and the displacement of the prosthesis/stent. The basic treatment of complications is the repositioning or insertion of an additional prosthesis.

(I) In patients with the N2 feature, the type of performed surgery, type of tumour and the occurrence of metastases in the lymph nodes of the lung hilum do not affect 5-year survival; (II) involvement of only one nodal group allows to achieve 5-year survival in 20% of patients; (III) involvement of three and more nodal groups with the N2 feature results in decreased 5-year survival.

IntroductionProgress in the development of surgical techniques has led to the growing use of video-assisted thoracoscopic surgery (VATS) techniques in mediastinal cyst treatment.AimTo present our experience of treating mediastinal cysts with the minimally invasive technique.Material and methodsFifty patients with mediastinal cysts were treated from 2001 to 2011. There were 32 women and 18 men. The age of the patients ranged from 17 to 72, the mean age being 42 years. All patients underwent basic preoperative diagnostic tests of the chest: X-ray, computed tomography (CT), bronchoscopy and spirometry; 4 patients underwent endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and 3 fine needle aspiration biopsy (FNAB) of the described lesions.ResultsThe VATS was performed in each case. Conversion was carried out due to superior mediastinal location in 10 cases and pleural adhesions in 3 cases. The partial resection of a cyst was performed in 3 patients. One patient was treated conservatively due to heart failure. In that patient the transthoracic needle aspiration of a cyst under ultrasound guidance using alcoholisation with 76% ethanol with a good effect was performed twice. Cyst recurrence was observed in 1 case.ConclusionsThe surgical access depends on the location of a cyst. The VATS resection of a superior mediastinal cyst is not always feasible. Surgery of mediastinal cysts is both diagnostic and curative.

A 38-year-old man presenting expiratory stridor and high-grade dyspnoea was admitted to hospital in Lodz in February 2013. Chest radiographs and computed tomography scans showed a solid lesion in the upper part of the trachea occluding 85% of the airway lumen. A segmental resection of the trachea with a subsequent end-to-end anastomosis was performed. Histopathology showed an extracutaneous glomus tumour. There were no postoperative complications. Tracheal resection is the primary curative method in cases of this rare tumour.

Aim of the studyAim of the study is to present our own experiences in the treatment of people suffering from penetrating neck traumas.Material and methodsIn the years 1996-2012, 10 patients with penetrating neck traumas were treated, including 3 women and 7 men. The patients’ age ranged from 16 to 55 (the average age being 40.7 years). In 9 cases the wound was caused by cutting or stabbing, while in one case it was inflicted by a gunshot. In 8 patients it was a single cut wound, while one patient suffered from 34 stab wounds to the neck, chest and stomach. Two cut wounds resulted from a suicide attempt. The remaining injuries were the result of a crime.ResultsAll patients underwent immediate surgery, which involved revision of the neck wounds in 8 cases, one longitudinal sternotomy and one left-sided thoracotomy. The indications for surgery included increased subcutaneous emphysema in 5 patients, bleeding from the wound in 3 patients, and mediastinal hematoma in 2 patients. The damage assessed intraoperatively included tracheal damage in 6 patients, damage to carotid vessels in 3 patients, larynx in 2 patients, thoracic vessels in 2 patients, oesophagus in 1 patient and thyroid gland in 1 patient. In 9 patients, the treatment yielded positive results. The patient with a gunshot wound died during the surgery due to massive bleeding from the aorta.ConclusionsIn patients with penetrating neck wounds, early and rapid diagnostics allows one to determine the indications for surgery and prevent serious fatal complications.
