RESUMO

BACKGROUND: This study aims to compare the safety and diagnostic accuracy of awake and intubated video-assisted thoracoscopic surgery in the diagnosis of pleural diseases. METHODS: This prospective randomized study was conducted between October 2016 and April 2018 and included 293 patients (201 males, 92 females; mean age 53.59 years; range, 18 to 90 years) from five medical centers experienced in video-assisted thoracoscopic surgery. The patients were randomized into two groups as awake video-assisted thoracoscopic surgery with sedoanalgesia (non-intubated) and video-assisted thoracoscopic surgery with general anesthesia (intubated). Patients with undiagnosed pleural effusions and pleural pathologies such as nodules and masses were included. Conditions such as pain, agitation, and hypoxia were indications for intubation. The groups were compared in terms of demographic data, postoperative pain, operative time, complications, diagnostic accuracy of the procedures, and cost. All patients completed a follow-up period of at least 12 months for samples that were non-specific, suspicious for malignancy or inadequate. RESULTS: Awake video-assisted thoracoscopic surgery was performed in 145 and intubated video-assisted thoracoscopic surgery was performed in 148 patients. Pleural disease was unilateral in 83% (243/293) and bilateral in 17% (50/293) of the patients. There was no difference between the groups in terms of presence of comorbidity (p=0.149). One patient in the awake video-assisted thoracoscopic surgery group (0.6%) was converted to general anesthesia due to refractory pain and agitation. As postoperative complications, fluid drainage and pneumonia were observed in one patient in the awake video-assisted thoracoscopic surgery group (0.6%) and fluid drainage was detected in one patient in the video-assisted thoracoscopic surgery group (0.6%). There were no differences in pain intensity measured with visual analog scale at postoperative 4, 8, 12, or 24 hours (p>0.05). Distribution and rates of postoperative pathological diagnoses were also similar (p=0.171). Both operative cost and total hospital cost were lower in the awake video-assisted thoracoscopic surgery group (p<0.001, p=0.001). CONCLUSION: Our study showed that awake video-assisted thoracoscopic surgery is safe, has similar reliability and diagnostic accuracy compared to video-assisted thoracoscopic surgery performed under general anesthesia, and is less costly. Awake video-assisted thoracoscopic surgery can be the first method of choice in all patients, not only in those with comorbidities.

RESUMO

AIM: The early diagnosis and treatment of lung cancer are important for the prognosis of patients with lung cancer. This study was undertaken to investigate patient and doctor delays in the diagnosis and treatment of NSCLC and the factors affecting these delays. MATERIALS AND METHODS: A total of 1016 patients, including 926 (91.1%) males and 90 (8.9%) females with a mean age of 61.5±10.1 years, were enrolled prospectively in this study between May 2010 and May 2011 from 17 sites in various Turkish provinces. RESULTS: The patient delay was found to be 49.9±96.9 days, doctor delay was found to be 87.7±99.6 days, and total delay was found to be 131.3±135.2 days. The referral delay was found to be 61.6±127.2 days, diagnostic delay was found to be 20.4±44.5 days, and treatment delay was found to be 24.4±54.9 days. When the major factors responsible for these delays were examined, patient delay was found to be more frequent in workers, while referral delay was found to be more frequent in patients living in villages (p<0.05). We determined that referral delay, doctor delay, and total delay increased as the number of doctors who were consulted by patients increased (p<0.05). Additionally, we determined that diagnostic and treatment delays were more frequent at the early tumour stages in NSCLC patients (p<0.05). DISCUSSION: The extended length of patient delay underscores the necessity of educating people about lung cancer. To decrease doctor delay, education is a crucial first step. Additionally, to further reduce the diagnostic and treatment delays of chest specialists, multidisciplinary management and algorithms must be used regularly.

RESUMO

The aim of this study was to investigate the protective effects of N-acetylcysteine (NAC) on peroxidative and apoptotic changes in the contused lungs of rats following blunt chest trauma. The rats were randomly divided into three groups: control, contusion, and contusion + NAC. All the rats, apart from those in the control group, performed moderate lung contusion. A daily intramuscular NAC injection (150 mg/kg) was given immediately following the blunt chest trauma and was continued for two additional days following cessation of the trauma. Samples of lung tissue were taken in order to evaluate the tissue malondialdehyde (MDA) level, histopathology, and epithelial cell apoptosis using terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay and active caspase-3 immunostaining. In addition, we immunohistochemically evaluated the expression of surfactant protein D (SP-D) in the lung tissue. The blunt chest trauma-induced lung contusion resulted in severe histopathological injury, as well as an increase in the MDA level and in the number of cells identified on TUNEL assay together with active caspase-3 positive epithelial cells, but a decrease in the number of SP-D positive alveolar type 2 (AT-2) cells. NAC treatment effectively attenuated histopathologic, peroxidative, and apoptotic changes, as well as reducing alterations in SP-D expression in the lung tissue. These findings indicate that the beneficial effects of NAC administrated following blunt chest trauma is related to the regulation of oxidative stress and apoptosis.

RESUMO

AIMS AND BACKGROUND: In late 2001 at our institution, we started offering induction radiochemotherapy as a treatment option for superior sulcus tumors. Our aim was to evaluate treatment choices and outcome in this patient group treated over the past 7 years at our institution. METHODS: The records of 34 patients were retrospectively reviewed and 33 were assessable for the analysis. RESULTS: Twenty of 28 patients with M0 disease had operable disease. The induction radiochemotherapy for superior sulcus tumors was possible in about two-thirds (14/20) of the cases with operable disease, with only one-third (5/14) of these having undergone surgery. The most common reason for not proceeding to surgery following induction radiochemotherapy was patient refusal (n = 5). The median follow-up of all 33 patients was 17 months. In curatively treated patients with (n = 11) or without surgery (n = 15), the median overall survival time was 26 months (range, 10-26) and 26 months (range, 7-71), respectively ( P = 0.534). Local-regional and/or distant failure developed in 20 of 26 patients treated curatively. In patients treated with the trimodality regimen (n = 5), no local-regional failure was observed, and distant failure occurred in one case. CONCLUSIONS: The trimodality treatment was possible in 25% of cases with operable disease due to the high rate of patient refusal to proceed to surgery following induction radiochemotherapy. No difference in survival was observed between patients treated with surgery and those treated with radiochemotherapy only because of a limited follow-up. So, the benefit of additional surgery is not clear, and a longer follow-up is needed before final conclusions can be drawn.

RESUMO

Solitary fibrous tumor (SFT) of the pleura is an uncommon neoplasm with non-specific symptoms and non-pathognomonical radiological findings. Surgery allows establishment of a definitive diagnosis as well as a cure of the disease. The role of radiotherapy or chemotherapy in the management of the disease is unclear because of the rarity of the disease and the successful results of the surgical treatment. Long-term clinical follow-up may be useful for the patients with SFT because of the potential adverse biological behavior of this tumor, which may lead to repeated recurrences and/or malignant transformation. We reported a 66-year-old woman with recurrence of SFT in the right lung, which had significant response to external thoracic radiotherapy.

RESUMO

Iodopovidone is an effective, safe, cheap, and easily available agent for pleurodesis. On the other hand, topical applications of iodopovidone may cause thyroid dysfunction. The purpose of this retrospective study was to determine the effects of intrapleural administration of iodopovidone on thyroid function. Twelve patients have undergone iodopovidone pleurodesis so far. A mixture of 20 ml 10% iodopovidone and 80 ml 0.9% saline solution was administered into the pleural cavity through the chest tube. Thyroid hormone (TSH, TT4, TT3, FT4, FT3) levels were routinely measured just before pleurodesis, and at the 24th and 72nd h of pleurodesis. No statistically significant alteration in thyroid function was determined (P>0.05). We did not observe any signs or symptoms of hyper- or hypothyroidism in any patient. Nine patients had a complete response to pleurodesis (75%). One patient who had undergone iodopovidone pleurodesis suffered from a moderate degree of transient chest pain. In conclusion, iodopovidone pleurodesis is safe and does not cause any thyroid dysfunction in normal adults.
