ABSTRACT

The efficacy of local instillation of fusidic acid in the prevention of post-surgical microbial complications during various types of lung resection was studied. Four hundred ninety two consecutive patients who underwent 504 thoracotomies for non-small cell lung carcinoma during April 1998-May 2004 were reviewed. The 290 patients of the first period who underwent 298 thoracotomies received a chemoprophylactic regimen of intravenous cefuroxime while the 202 patients of the second period who underwent 206 thoracotomies were additionally treated with fusidic acid, irrigated with local instillation into the pleural space, for the prevention of postoperative septic complications. Patients were followed postoperatively for development of septic complications (empyema and bronchopleural fistula) as well as of pneumonia and wound infection. Seventeen patients (5.7%) of the first period developed empyema and 13 fistula (4.4%), whereas only 2 patients (1.0%) of the second period developed empyema and fistula (OR = 5.876; 95% CI, 1.343- 25.716; P = 0.008 and OR = 4.193; 95% CI, 1.003-20.130; P = 0.034, respectively). Cases of pneumonia decreased, but not significantly, from 21 (7.0%) during the first period to 9 (4.4%) during the second period (OR = 1.613; 95% CI, 0.724-3.593; P = 0.257) while cases of wound infection decreased significantly from 19 (6.4%) to 2 (1.0%) (OR = 6.567; 95% CI, 1.513-28.510; P = 0.003). During the first period 23 pathogens were found from cases of empyema and 73 pathogens from cases of pneumonia and wound infection, whereas during the second period 3 and 18 pathogens were respectively found (OR = 5.3; 95% CI, 1.570-17.888; P = 0.003, and OR = 2.804; 95% CI, 1.628-4.838; P <0.001, respectively). These results indicate that local instillation of fusidic acid in the pleural space prior to lung resection seems effective in reducing the rate of septic complications as well as of wound infections.

ABSTRACT

PURPOSE: Lung cancer is the most common cause of cancer death in both men and women in our country. It has been estimated that there will be 6,000 lung cancer deaths every year in Greece. However, many patients with bronchogenic carcinoma also have coexistent obstructive lung disease. In these patients, preoperative prediction of functional status after lung resection is mandatory. The aim of our study was to determine the effect of lung resection on postoperative spirometric lung function. PATIENTS AND METHODS: 112 patients underwent spirometric pulmonary tests preoperatively, and at 3 and 6 months after their operation. The predicted postoperative forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1) were calculated using the formula of Juhl and Frost: predicted postoperative FEV1 (or FVC)=preoperative FEV1(or FVC) x[1-(S x 0.0526)], where S=number of segments resected. Statistical significance was defined as a p value < 0.05. RESULTS: The functional percentage losses at 6 months for lobectomies and pneumonectomies were 7.34% and 34.89% for FVC and 7.72%; and 32.53% for FEV, respectively. The linear regression analysis derived from the correlation between predicted and measured FEV1 resulted in 2 equations for lobectomy and pneumonectomy. The first, for lobectomy, was: FEV1POSTOP=0.00211 + 0.896660 x FEV1PREOP; and the second, for pneumonectomy, was: FEV1POSTOP=0.145 + 0.65318 x FEV1PREOP. CONCLUSION: We conclude that our formulas are a reliable method for predicting postoperative respiratory function of the patients with lung cancer.

ABSTRACT

PURPOSE: Superior vena cava (SVC) syndrome is caused by SVC stenosis or occlusion, frequently as a consequence of lung cancer or a mediastinal tumor. SVC syndrome is characterized by unpleasant symptoms and the condition usually leads to death if untreated. Treatment with radiation therapy and chemotherapy may produce an initial relief, whereas operations with bypass are associated with high mortality and morbidity. The PURPOSE of our study was to show the efficiency of percutaneous stenting in the SVC for relieving SVC syndrome secondary to malignant diseases. PATIENTS AND METHODS: From January 1999 to March 2003, 17 patients with malignant SVC syndrome were evaluated at the "Metaxa" Cancer Hospital. Their caval stenoses were confirmed by means of computed tomography and venography. There were 15 males and 2 females with a median age of 62 years (range 47-79). The SCV syndrome was caused by malignant disease in all patients: bronchogenic carcinoma in 14 and lymphoma in 3. All patients underwent placement of a self-expandable (wallstent) endovascular (vena cava) prosthesis. RESULTS: All procedures were successfully carried out without complications. The average time for wallstent placement was 37 min. There was no sign of bleeding and the wallstent was well positioned on chest roentgenograms. All patients, without exception, noticed an immediate improvement, with relief of dyspnea and rapid resolution of headache. Cyanosis disappeared over the first hour and swelling resolved gradually over the first 24 hours. CONCLUSION: Percutaneous venous wallstent placement in the SVC is a simple, safe and effective technique to rapidly relieve SVC syndrome caused by malignant diseases.

ABSTRACT

Small cell lung cancer (SCLC) is considered a systemic disease at diagnosis, because the potential for hematogenous and lymphogenic metastases is very high. For many years, the diagnosis of SCLC was considered a contraindication for surgery because radiotherapy was at least equivalent in terms of local control, and the rate of resectability in SCLC patients was poor. When chemotherapy became the mainstay of treatment for SCLC, radiotherapy was its logical complement, and surgery was progressively abandoned. However, some centers continued to support surgery because experience suggested that in selected patients it was possible to achieve a long-term survival. In the search for predictors of long-term survival it became evident that the TNM staging system was effective for SCLC. The rationale for surgery in the context of SCLC is based on 3 factors: a) Several historical series of patients operated for limited-stage SCLC reported some long-term survivors, showing that cure could be achieved. b) After chemotherapy and radiotherapy, the rate of local relapse is 20%-30%. The assumption that surgical resection might be superior for local disease control has been suggested but not yet proved. c) The surgical intervention can precisely assess pathological (p) response to chemotherapy, identify carcinoids erroneously diagnosed as SCLC, and treat the non-small cell lung cancer (NSCLC) component of tumors with a mixed histology. Even if some controversies exist, it is accepted that surgery can be proposed as the first treatment in patients with T1 or T2 lesions with no evidence of lymph node involvement, followed by adjuvant chemotherapy. In more advanced stages of disease, chemotherapy should be the first step of treatment and surgery can be proposed to responding patients, before radical radiotherapy, depending on the p-stage of disease. Such an intensive multidisciplinary approach should be always employed in the context of controlled clinical trials.
