Surgery for patients with gastric cancer in the terminal stage of the illness - TNM stage IV.

PURPOSE: To assess any survival advantage in patients with incurable gastric cancer who had undergone resection, bypass or exploratory surgery. In nonresectable patients with pain, the effect of celiac plexus neurolysis was assessed. METHODS: We retrospectively analysed data of 330 patients, operated between 1992 and 2006. The patients were followed until death or last examination. Incurable gastric cancer was defined as TNM stage IV disease: locally advanced (LA), with solitary distant metastasis (SM) or with multiple metastases and/or peritoneal carcinomatosis (MMC). The patients were divided into these 3 groups. Their postoperative survival was calculated and compared in relation to the surgical technique used. Factors which influenced mortality and survival were identified. RESULTS: 131 patients (39.7%) had locally LA cancer, 98 (29.7%) SM, and 101 (30.6%) belonged to the MMC group. The surgical procedures included 138 (41.8%) exploratory laparotomies, 84 (25.5%) bypass procedures and 108 (32.7%) resections. Thirty-three (10%) unresectable patients with pain underwent celiac plexus neurolysis. The mean survival was 21.8 months after resections, 7 months after by-passes and 4.8 after exploratory laparotomies (p = 0.0001). It was 14.57 months (p=0.001) in the LA group, 12.53 (p = 0.005) in the SM group, and 5.2 in the MMC group. Survival was shorter in patients with preoperative weight loss of more than 20 kg (3.2 months, p <0.0001). Postoperative 30-day mortality was 23.2% after exploratory laparotomies, 23.8% after bypasses and 20.4% after resections. Increased mortality was observed in the MMC group (27.7%) and in multivisceral resections (41%, p > 0.05), while significantly increased mortality occurred in patients with weight loss of over 20 kg (32%, p=0.03). Celiac plexus neurolysis was immediately effective in 30 out of 33 (91%) patients (p=0.0001), while 3 months later it was still effective in 15 (45.5%) patients (p=0.08). CONCLUSION: Resections are suggested in the LA and SM groups, and neurolysis in all nonresected patients with pain.

The effect of Nd:YAG laser resection on symptom control, time to progression and survival in lung cancer patients.

PURPOSE: The aim of this study was to determine the effect of Nd:YAG laser resection of centrally located tumors on the control of various symptoms and signs, time to progression and survival in lung cancer patients. PATIENTS AND METHODS: We evaluated the effects of Nd: YAG laser resection in combination with high-dose rate (HDR) brachytherapy and external beam radiotherapy (EBRT) vs. combination of HDR brachytherapy and EBRT alone on lung cancer symptoms and signs, ECOG performance status, time to progression and overall survival in lung cancer patients. Patients in group I (n=81) were treated with combination of HDR brachytherapy and EBRT, while patients in group II (n=97) were treated with Nd:YAG laser in combination with HDR brachytherapy and EBRT. Patients were evaluated before and after treatment, and were followed-up regularly every 3 months until the end of life. After RT +/- laser treatment all patients received standard chemotherapy (cisplatin plus etoposide) during the course of disease. RESULTS: After treatment in both groups significant improvement in all investigated parameters was seen. Improvement in dyspnoea, thoracic pain, body weight loss and ECOG performance status was significantly better in group II (p <0.05), as were time to progression and overall survival (p <0.05). CONCLUSION: Laser resection improves symptom control in lung cancer patients with central airway obstruction (CAO). Longer time to progression and survival of lung cancer patients could be the result of imminent airway desobstruction accomplished with Nd:YAG laser.

Interventional pulmonology techniques for immediate desobstruction of malignant central airway obstruction.

In recent years interventional pulmonology techniques have found their place in the palliative treatment of lung cancer invading central airways (trachea and principal bronchi). The curative effect of interventional techniques is reported in a number of studies with very different success ratios, but with excellent potential and perspective. Increase in number and variety of these techniques led to the development of internationally accepted guidelines for their use. The choice of a specific interventional technique in the treatment of lung cancer patients with central airway obstruction (CAO) depends on several factors: patient's general condition and comorbidities, type and characteristics of airway stenosis, availability of techniques and trained personnel. The aim of this review was to introduce interventional pulmonology procedures aimed at urgent desobstruction of central airways obstruction to medical oncologists who are dealing with the problem of malignant CAO. We tried to emphasize indications, contraindications, technique procedure and possible complications in the treatment of malignant CAO. At the Institute for Pulmonary Diseases of Vojvodina Nd: YAG laser resection, electrocautery, argon plasma coagulation and metallic and silicone stent insertions for immediate treatment of malignant CAO are practised.

Combination of interventional pulmonology techniques (Nd:YAG laser resection and brachytherapy) with external beam radiotherapy in the treatment of lung cancer patients with Karnofsky Index < or =50.

PURPOSE: To compare Nd: YAG laser resection with Nd: YAG laser plus brachytherapy and external beam radiotherapy (EBRT) in the palliation of malignant central airway obstruction symptoms due to lung cancer. PATIENTS AND METHODS: In this prospective non-randomized study we evaluated the effects of Nd:YAG laser photoresection alone vs. Nd:YAG laser resection in combination with brachytherapy and EBRT on cough, dyspnoea, thoracic pain, haemoptysis, body weight loss, atelectasis, postobstructive pneumonia, endoscopic findings, disease-free period and survival rate in lung cancer patients. Only patients with Karnofsky index (KI) < or =50 were included. Sixty-four patients were divided into 2 groups: group I patients ( = 20) were treated only with Nd: YAG laser, and group II patients (n = 44) were treated with Nd: YAG laser followed by brachytherapy and EBRT. RESULTS: Group I patients showed statistically significant improvement in all investigated parameters but cough. Group II patients achieved significant improvement in all investigated parameters. Comparative statistical analysis between the 2 groups revealed statistically significant improvement in group II with regard to dyspnoea, haemoptysis, KI and atelectasis. No significant improvement in group II was seen when other investigated parameters were considered. Disease-free period and survival rate were significantly longer in group II (p< or =0.0005). CONCLUSION: The combination of interventional pulmonology procedures with standard modalities is the best option for the treatment of selected lung cancer patients.

Early complications following total gastrectomy for gastric cancer.

BACKGROUND: The study shows operative results with complications occurring in first 30 days after total gastrectomy for stomach cancer. METHODS: A retrospective analysis was performed using medical documentation and histological findings for 76 patients after total gastrectomy was done between 1990 and 1997. Mortality and postoperative complications were analyzed. Complications were sorted as specific and nonspecific. All operations were performed either for intestinal gastric cancer located in proximal stomach or for diffuse stomach cancer. All anastomoses were hand sewn. RESULTS: There were 43 male and 33 female patients. Postoperative mortality was 14.4%. The most frequent complications were dehiscence of the oesophago-jejunal anastomosis in 15.8% of operated patients, postoperative temperature without apparent infection in 5.2%, thrombophlebitis in 5.2%, pneumothorax in 3.9%, hepatic necrosis in one patient (1.3%), and perforation of jejunal loop with nasogastric tube in another (1.3%) ended fatally. The average postoperative intra-hospital treatment lasted 12.3 days. Dehiscence of the oesophago-enteric anastomosis, resulted in generalized peritonitis in 66.6%. Six patients succumbed as a consequence, while two survived with subphrenic and interenteric abscesses. Pneumothorax in combination with total gastrectomy was always fatal. CONCLUSIONS: Routine use of stapling surgery, subspecialization in surgery, and better early intensive care monitoring and treatment could reduce the mortality rate.

[Respiratory tract hemorrhage]. / Krvarenje iz respiratornog trakta.

Bleeding from the respiratory tract can be met in everyday clinical practice. The number of patients with bleeding is not small, which implies that every physician should have adequate knowledge in order to react promptly, when needed. We have underlined the causes and the accessory factors which promote bleeding, localization--upper and lower respiratory tract, diagnostic methods which are available, prevention and treatment of bleeding.
