ADENOID CYSTIC CARCINOMA OF DISTAL TRACHEA: A CASE REPORT.

Primary malignant tumors of the trachea are very rare with the incidence of less than two per million people per year, and only ten percent of them are adenoid cystic carcinomas. Eighty percent of all tracheal tumors are malignant. Diagnosis is usually late because the symptoms mimic other conditions such as asthma. Clinical picture may sometimes be dramatic when airway is almost closed and emergency recanalization is necessary. Diagnosis is made by chest computed tomography scan or magnetic resonance imaging. Definitive treatment is surgical resection alone or followed by radiation therapy or radiation therapy alone. Radical resection is only accomplished in about half of all cases because of the submucosal tumor growth and limited length of tracheal resection. The role of adjuvant radiation therapy in negative resection margin cases is not clear but all patients with positive resection margin benefit from radiation therapy. We present a case of a 43-year-old patient with primary adenoid cystic carcinoma of distal trachea treated by emergency bronchoscopic recanalization and resection of the tracheal tumor with end-to-end anastomosis.

[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.

Stairs climbing test with pulse oximetry as predictor of early postoperative complications in functionally impaired patients with lung cancer and elective lung surgery: prospective trial of consecutive series of patients.

AIM: To test the predictive value of stairs climbing test for the development of postoperative complications in lung cancer patients with forced expiratory volume in one second (FEV1)<2 L, selected for an elective lung surgery. METHODS: The prospective study was conducted in 101 consecutive patients with an FEV1<2 L selected for elective lung surgery for lung cancer. Preoperative examination included medical history and physical examination, lung function testing, electrocardiography, laboratory testing, and chest radiography. All patients underwent stairs climbing with pulse oximetry before the operation with the number of steps climbed and the time to complete the test recorded. Oxygen saturation and pulse rate were measured every 20 steps. Data on postoperative complications including oxygen use, prolonged mechanical ventilation, and early postoperative mortality were collected. RESULTS: Eighty-seven of 101 patients (86%) had at least one postoperative complication. The type of surgery was significantly associated with postoperative complications (25.5% patients with lobectomy had no early postoperative complications), while age, gender, smoking status, postoperative oxygenation, and artificial ventilation were not. There were more postoperative complications in more extensive and serious types of surgery (P<0.001). The stairs climbing test produced a significant decrease in oxygen saturation (-1%) and increase in pulse rate (by 10/min) for every 20 steps climbed. The stairs climbing test was predictive for postoperative complications only in lobectomy group, with the best predictive parameter being the quotient of oxygen saturation after 40 steps and test duration (positive likelihood ratio [LR], 2.4; 95% confidence interval [CI], 1.71-3.38; negative LR, 0.53; 95% CI, 0.38-0.76). In patients with other types of surgery the only significant predictive parameter for incident severe postoperative complications was the number of days on artificial ventilation (P=0.006). CONCLUSION: Stairs climbing test should be done in routine clinical practice as a standard test for risk assessment and prediction of the development of postoperative complications in lung cancer patients selected for elective surgery (lobectomy). Comparative to spirometry, it detects serious disorders in oxygen transport that are a baseline for a later development of cardiopulmonary postoperative complications and mortality in this subgroup of patients.

Successful use of activated recombinant factor VII in life threatening bleeding after thoracic surgery.

We present three patients in whom life-threatening haemorrhage following lung resection was successfully managed using activated recombinant factor VII (NovoSeven). In one case, activated recombinant factor VII was the only therapy administered to manage bleeding, and in the two remaining cases, activated recombinant factor VII was administered after patients failed to respond to conventional therapy. All patients demonstrated effective haemostasis and improved coagulation parameters as a result of treatment with activated recombinant factor VII. Our experience with the clinical use of rFVIIa suggests that this agent may provide effective hemostasis following lifethreatening postoperative bleeding after major thoracic surgery. Despite these favorable results, randomized, placebo - controlled trials are needed to identify optimal treatment strategy, patient selection, and safety of treatment in patients with massive bleeding following major thoracic surgery.
