Lung cancer from suspicion to treatment: An indicator of healthcare access in Turkey.

BACKGROUND: Lung cancer is the leading cause of cancer-related deaths worldwide. Before beginning lung cancer treatment, it is necessary to complete procedures such as suspecting lung cancer, obtaining a pathologic diagnosis, and staging. This study aimed to investigate the processes from suspicion of lung cancer to diagnosis, staging, and treatment initiation. METHODS: The study was designed as a multicenter and cross-sectional study. Patients with lung cancer from various health institutions located in all geographic regions of Turkey were included in the study. The sociodemographic and clinical characteristics of the patients, the characteristics of the health institutions and geographic regions, and other variables of the lung cancer process were recorded. The time from suspicion of lung cancer to pathologic diagnosis, radiologic staging, and treatment initiation, as well as influencing factors, were investigated. RESULTS: The study included 1410 patients from 29 different medical centers. The mean time from the initial suspicion of lung cancer to the pathologic diagnosis was 48.0 ± 52.6 days, 39.0 ± 52.7 days for radiologic staging, and 74.9 ± 65.5 days for treatment initiation. The residential areas with the most suspected lung cancer cases were highly developed socioeconomic zones. Primary healthcare services accounted for only 0.4% of patients with suspected lung cancer. The time to pathologic diagnosis was longer in the Marmara region, and the wait time for staging and treatment initiation was longer in Eastern and Southeastern Anatolia. Patients who presented to chest disease referral hospitals with peripheral lesions, those with early-stage disease, and those who were diagnosed surgically had significantly longer wait times. CONCLUSION: The time between pathologic diagnosis, staging, and treatment initiation in lung cancer was longer than expected. Increasing the role of primary healthcare services and distributing socioeconomic resources more equally will contribute to shortening the time to diagnosis and improve treatment processes for lung cancer.

Lung Cancer Surgery in Patients With a History of Coronary Artery Bypass Graft: A Multicentre Study.

BACKGROUND: Lung cancer surgery may be required for patients with a history of coronary artery bypass graft (CABG). In this study, we evaluated the general characteristics of patients, the difficulties experienced during and after lung cancer surgery and complications and mortality rates. METHOD: Patients who were operated on for primary lung cancer between January 2012 and July 2017 in the participating centres were analysed retrospectively (n=7,530). Patients with a history of CABG (n=220) were examined in detail. This special group was analysed and compared with other patients operated on for lung cancer who did not have CABG (n=7,310) in terms of 30-day mortality and revision for haemorrhage. RESULTS: Of the 7,530 patients operated on for primary lung cancer, 2.9% were found to have undergone CABG. Surgical revision was required in the early postoperative period for 6.8% of those who had CABG and 3.5% in those who did not have CABG (p=0.009). Thirty-day (30-day) mortality was 4.5% in those who had CABG and 2.9% in those who did not have CABG (p=0.143). Further analysis of patients who had undergone CABG demonstrated that video-assisted thoracoscopic surgery (VATS) resulted in fewer complications (p=0.015). Patients with a left-sided left internal mammary artery (LIMA) graft had a higher number of postoperative complications (p=0.30). CONCLUSIONS: Patients who had CABG suffered postoperative haemorrhage requiring a revision twice as often, and a tendency towards higher mortality (non-statistically significant). In patients with a history of CABG, VATS was demonstrated to have fewer complications. Patients with a LIMA graft who had a left-sided resection had more postoperative complications.

Is there any relationship between quality of life and the level of sympathectomy in primary palmar hyperhidrosis? Single-center experience.

BACKGROUND: The discussions at the surgical levels (sympathectomy levels) about endoscopic thoracic sympathectomy (ETS) method, which is applied in hyperhidrosis treatment in the present day and acknowledged as the golden treatment method, continue. Mainly, most of the studies evaluates postoperative early period results. Our aim in this study is to compare the long-term quality of life depending on the different surgical levels (sympathectomy levels) and evaluate the postoperative complications. METHODS: 165 patients operated due to palmar hyperhidrosis between January 2012 and July 2017 were evaluated. Sympathectomy was performed either by clipping or cauterization and sympathetic nerves included were T2-4, T3-4, or T3 levels. Data were retrospectively reviewed for complications, factors affecting the postoperative quality of life. RESULTS: Ninety of the patients were male (54.5%) and 75 (45.5%) were female. The level of ganglion block was T2-T4 in 62 patients (37.6%), T3-T4 in 46 patients (27.9%), and T3 in 57 patients (34.5%). Early complications were observed in 27 patients (16.4%). Compensatory hyperhidrosis (CH) was observed in 62 patients (37.6%). There was a significant difference in the postoperative quality of life according to ETS level (p < 0.001). Patients who underwent T2-T4 sympathectomy had a lower quality of life than patients who underwent isolated T3 or T3-T4 sympathectomy. CONCLUSION: Based on our results, we recommend performing lower level resections to increase the long-term quality of life in palmar hyperhidrosis patients. The lower risk of CH and comparable quality of life suggest that T3 sympathectomy is more effective.

Long-Term Outcomes of Carinal Sleeve Resection in Non-Small Cell Lung Cancer.

BACKGROUND: Carinal resections for non-small cell lung cancer (NSCLC) invading the carina are challenging cases that require a therapeutic strategy. The aim of this study was to compare the oncologic outcomes and complications of patients who underwent carinal resection. METHODS: Sixty-four patients who underwent carinal resection between 2005 and 2016 were evaluated. Data were retrospectively reviewed for indications, complications, and factors influencing long-term survival. RESULTS: The study included 51 patients (79.7%) who underwent sleeve pneumonectomy (sP) and 13 patients who underwent carinal sleeve lobectomy (csL) as a curative therapy. Nine patients (14.1%) received induction chemotherapy. Complications were observed in 31 patients (48.8%), including 24 patients (47.1%) in the sP group and 7 patients (53.8%) in the csL group (p = 0.662). Six patients (9.4%) developed bronchopleural fistula. The 30-day mortality rate was 10.9% (n = 7). The 5- and 10-year survival rates were 42.2 and 23.1%, respectively. N2 and R1 were identified as factors affecting survival (p = 0.029 and p = 0.047). CONCLUSION: Carinal resections have acceptable morbidity, mortality, and long-term survival outcomes in central NSCLC. The main factors affecting survival are complete resection and nodal status. The results of csL were similar to those of sP. Therefore, we believe that csL should be performed in all eligible patients.

Is Right Sleeve Lower Lobectomy Necessary? Is It Safe?

OBJECTIVES: The right sleeve lower lobectomy is the least used of the bronchial sleeve operations. There are only case-based studies in the literature. In this study, we compared this technique to those used in patients who underwent a right lower bilobectomy. METHODS: We retrospectively reviewed the data of patients who had been operated on due to non-small cell lung cancer (NSCLC) from January 2005 to December 2015 from a dataset that was formed prospectively. Of the 4,166 patients who underwent resections due to NSCLC, the files of those who had a right sleeve lower lobectomy (group S) and those who had a right lower bilobectomy (group B) were evaluated. The remaining 25 patients in group B and 18 patients in group S were compared in terms of demographic data, morbidity, hospitalization time, mortality, histopathology, recurrence, and total survival. RESULTS: No significant differences in the demographic or clinical characteristics were observed between the two groups, except that group S had more female patients. Postoperative complications developed in 52% of the patients in group B and 11.1% of the patients in group S (p = 0.006). Mean hospitalization time was 9.6 ± 3.6 (range, 6-19) days in group B and 6.72 ± 1.5 (range, 4-9) days in group S (p = 0.001). All patients received complete resections. The mean patient follow-up time was 42.9 months. No significant difference was found between local and distant recurrences (p = 1, p = 0.432). Mean survival time was 89.6 months (5-year rate = 73%), which was 90.6 months (5-year rate = 75.3%) in group B and 63.1 months (5-year rate = 69.3%) in group S (p = 0.82). CONCLUSION: This technique allows for reduced filling of the thoracic cavity by a prolonged air leak and a reduced prevalence of complications. Additionally, the hospitalization time is shortened. It does not produce any additional mortality burden, and total survival and oncological outcomes are reliable. This technique can be used in selected patients at experienced centers.

Transcervical mediastinoscopy in patients with a permanent tracheostomy: is it feasible?

OBJECTIVES: Cervical mediastinoscopy may become essential in patients with pathological lymph nodes at mediastinum after laryngectomy. However, having had a previous tracheostomy has been reported to be a contraindication for cervical mediastinoscopy. METHODS: Between January 2010 and December 2017, cervical mediastinoscopy was performed for lung cancer staging in 1985 patients at the Department of Thoracic Surgery, Yedikule Chest Diseases and Thoracic Surgery Education and Research Hospital, Istanbul, Turkey. Eighteen of these patients (1%) had a permanent tracheostomy after total laryngectomy and cervical radiotherapy due to laryngeal carcinoma. RESULTS: Cervical mediastinoscopy was performed in 18 patients with a permanent tracheostomy after total laryngectomy. The negative predictive value of cervical mediastinoscopy was 13/14 (93%). The average operative time was 63 min (SD 12.0, range 50-90 min). The negative predictive value of endobronchial ultrasonography was 4/7 (57%). Positron emission tomography-computed tomography had a positive predictive value of 3/15 (20%) and a negative predictive value of 2/3 (67%). CONCLUSIONS: Contrary to the claims of 2 textbooks, cervical mediastinoscopy is a viable method for patients with a tracheostomy after laryngectomy. The negative predictive values of standard cervical mediastinoscopy and mediastinoscopy for patients with a tracheostomy after total laryngectomy are approximately equivalent. Our results indicate that cervical mediastinoscopy is a feasible method in patients with a permanent tracheostomy when applied by experienced thoracic surgeons in specialized hospitals.

Are flexible bronchoscopic cryoextraction practices an alternative to rigid bronchoscopy?

INTRODUCTION: We aimed to evaluate the efficacy of flexible bronchoscopic cryoextraction in the treatment of airw ay obstruction arise from mucus plugs and blood clots and present our experience. MATERIALS AND METHODS: The present study evaluated patients who previously underwent unsuccessful flexible bronchoscopy for the removal of secretions and blood clots in the central airway and who underwent flexible bronchoscopic cryoextraction between January 2013-November 2017. RESULT: The study included seven patients with a mean age of 58.29 ± 18.56 years (28-76). Three patients underwent bedside intervention in the intensive care unit, and four patients underwent an intervention in the bronchoscopy unit. Seven patients underwent a total of nine sessions of cryoextraction. Severe complications or mortality did not occur during the cryoextraction sessions. CONCLUSIONS: Flexible bronchoscopic cryoextraction offers a safe treatment strategy as an alternative to rigid bronchoscopy in patients in whom airway patency cannot be achieved using other flexible bronchoscopic interventions. and accuracy of PET was higher compared to CT with this cut-off value.

Unexpected conversion to thoracotomy during thoracoscopic lobectomy: a single-center analysis.

BACKGROUND: The aim of this study was to discuss indications and outcomes for conversion to thoracotomy during thoracoscopic lobectomy. MATERIALS AND METHODS: Patients who underwent lobectomy for non-small cell lung cancer between January 2012 and December 2016 were evaluated retrospectively. The study included 129 patients who underwent video-assisted thoracoscopic lobectomy (group-V) and 18 patients converted from thoracoscopic lobectomy to thoracotomy due to unexpected intraoperative complications (group-T). RESULTS: The two patient groups showed no statistical differences in terms of demographic characteristics. Causes of unexpected conversions to thoracotomy were hemorrhage in six patients, dense pleural adhesions in seven patients, fused fissure in one patient, and fibrocalcified lymph nodes around the vascular structures in four patients. Operative time was 180.37 ± 68.6 min in group-V and 235 ± 72.6 min in group-T (p = 0.003). Intraoperative blood loss was 263.9 ± 180.6 mL in group-V, compared to 562.7 ± 296.2 mL in group-T (p < 0.001). Patient age ≥ 70 years was a significant risk factor for conversion to thoracotomy (p = 0.015, odds ratio 4.73). The 5-year survival rate in group-V was 71.4% {mean: 65.2 months [95% confidence interval (CI) 59.6-70.8]}, while that in group-T was 80% [mean 54.9 months (95% CI 45.9-63.8)] (p = 0.548). CONCLUSION: Advanced age was identified as the main risk factor for conversion to thoracotomy. However, early- and long-term outcomes were similar in the two groups, indicating that video-assisted thoracoscopic surgery is a safe and applicable method.

The Effectiveness of Sterile Wound Drapes in the Prevention of Surgical Site Infection in Thoracic Surgery.

BACKGROUND: The rate of surgical site infections (SSIs) has decreased in parallel to advances in sterilization techniques. Such infections increase morbidity and hospitalization costs. The use of iodine-impregnated sterile wound drapes (SWDs) is recommended to prevent or reduce the incidence of these infections. However, there is a paucity of data regarding their use in thoracic surgical procedures. The aim of the present study was to evaluate the effectiveness of sterile wound drapes in the prevention of these infections and the effects on hospitalization costs. METHODS: Perioperative iodine-impregnated SWDs have been used since January 2015 in the Thoracic Surgery Clinic of our hospital. A retrospective evaluation was made of patients who underwent anatomic pulmonary resection via thoracotomy with SWD in the period January 2015-2017, compared with a control group who underwent the same surgery without SWD in the 2-year period before January 2015. Factors that may have increased the risk of surgical site infection were documented and the occurrence of SSI was recorded from postoperative follow-up data. The cost analysis was performed as an important criterion to investigate the benefits of SWD. RESULTS: Evaluation was made of 654 patients in the study group (n:380) using SWD, the operation time was significantly longer, and perioperative blood transfusion was significantly higher, whereas treatment costs (p=0.0001) and wound culture positivity (p=0.004) were significantly lower and less surgical wound debridement was performed (p=0.002). CONCLUSION: The findings suggest that the use of sterile wound draping in thoracic surgery procedures reduces surgical site infections and hospitalization costs.

Long-term outcomes of completion pneumonectomy for non-small cell lung cancer.

Background: Completion pneumonectomy (CP) is the removal of remaining lung tissue after initial resection. Our aim in this study was to investigate the factors affecting mortality, morbidity, and survival after CP. Methods: Patients who underwent CP in our clinic between January 2000 and December 2015 were evaluated retrospectively. The patients' demographic information, morbidity, mortality, histopathological characteristics, and 2-, 5-, and 10-year survival were evaluated. Results: Of the 32 non-small cell lung cancer patients in the study, 31 (96.9%) were male and one (3.1%) was female. The postoperative mortality rate was 9.4% and the morbidity rate was 46.9%. The most common complication was atrial fibrillation (31.3%). Median survival time was 67 ± 10.3 months; 5- and 10-year survival rates were 50.3 and 31.2%, respectively. Conclusion: Completion pneumonectomy involves an acceptable mortality rate but high morbidity rate. Based on the results of this study, the interval between initial resection and CP does not affect survival time.

Synchronous chondrosarcoma originating from two distant ribs.

A chondrosarcoma is a rare bone tumour derived from cartilage-producing malignant mesenchymal cells. A 25- year-old male patient was operated upon to treat a chondrosarcoma arising in the left 2nd and 6th ribs. The tumour underwent en bloc wide resection in collaboration with a plastic surgeon for reconstruction of the resected area. Costal chondrasarcoma is very rare but chondrosarcoma arising from two ribs at the same time has not been reported before in the literature.

Videothoracoscopic lobectomy training in non-small cell lung cancer.

BACKGROUND: This study aims to evaluate the outcomes of video-assisted thoracoscopic surgery lobectomies performed by a training consultant or an experienced consultant. METHODS: The study included 103 patients (81 males, 22 females; mean age 59.6±9.5 years; range, 32 to 84 years) who underwent video-assisted thoracoscopic surgery lobectomy due to non-small cell lung cancer. The training consultant assisted on the same side with the experienced consultant during the operations of the experienced consultant. The experienced consultant observed in the operating room and provided advice from a distance during the first five operations of the training consultant. Comorbidities, postoperative complications, and mortality were evaluated. RESULTS: Patients" demographic characteristics, comorbidities, and postoperative complications were similar between the two surgeons (p>0.05). Operative time, incidence of prolonged air leak, and length of hospital stay were higher in procedures performed by the training consultant (p<0.05). There were no significant differences in rates of life-threatening complications or mortality. CONCLUSION: Video-assisted thoracoscopic surgery lobectomy can be performed safely by surgeons in training. Effective training programs may produce outcomes comparable to those of experienced surgeons.

A rare intrathoracic mass: Accessory liver lobe.

A heterotopic, supradiaphragmatic liver tissue is an extremely rare entitiy. It is usually asymptomatic and is often detected incidentally. Herein, we report a female case who had coughinduced occasional back and chest pain and in whom an intrathoracic paravertebral mass was radiographically detected.

Is the Outcome of Pulmonary Resections due to Non-Small Cell Lung Cancer in Octogenarian Patients Worse?

PURPOSE: Lung cancer is one of the major sources of mortality in the elderly. This study was undertaken to assess the early and long-term results of surgical resection in patients older than 70 years of age by comparing the results of patients aged 70-79 years (group 1) with patients older than 80 years of age (group 2). METHODS: Data on patient age, gender, spirometry values, side, size, histology and stage of the tumor, surgical procedures, postoperative complications, Charlson comorbidity scores (CCS), and survival were collected. RESULTS: After 1-2 propensity score matching group 1 (70-79 years) included 84 and group 2 (age over 80) 42 cases. The multivariate analysis showed that CCS was the only significant factor affecting the development of complications (p = 0.003). The overall median and 5-year survival of all patients were 55 months and 42.5%, respectively. Although the survival of the elderly group 2 was higher than the first group, the difference did not reach significance (50 vs. 49 months, respectively). CONCLUSION: The outcomes of surgery in terms of morbidity and mortality rates do not differ between the two age groups. The safety of pulmonary resections in the elderly group is comparable to patients under 70 years if the comorbidities are appropriately controlled. In addition, surgery provides satisfactory survival rates in both age groups.

Which is the Best Minimal Invasive Approach for the Treatment of Spontaneous Pneumothorax? Uniport, Two, or Three Ports: A Prospective Randomized Trail.

OBJECTIVE: Video-assisted thoracoscopic surgery (VATS) has become the standard treatment method for primary spontaneous pneumothorax. Concerns about lesser pain and better cosmesis led to the evolution of uniportal access. This study prospectively compared the results of the uniportal, two-port, and three-port thoracoscopic surgery. MATERIAL AND METHODS: One hundred and thirty-five patients were randomized into three groups according to the port numbers. The groups were compared regarding the operation time, hospital stay, amount of drainage, area of pleurectomy, complications, recurrences, and pain scores. RESULTS: Except for the amount of drainage (p = 0.03), no factors were found to be statistically significant. The overall recurrence rate was 5%. Although the first and second week pain scores were not statistically significant, the single-incision group patients had significantly less pain at 4, 24, and 72 hours (p < 0.05). CONCLUSION: The study indicated that uniportal VATS approach is less painful and has better cosmetic results, besides it is as efficient as two- or three-port VATS approach.

Bronchial Stump Recurrence after Complete Resection of Lung Cancer: Effect of the Distance between the Tumor and Bronchial Resection Margin.

PURPOSE: The purpose of this study was to evaluate the following parameters after complete resection in established lung cancer patients: the frequency of bronchial stump recurrence (BSR), the effect of the distance between the tumor and bronchial resection margin (DBTM) on BSR, the survival of patients with BSR, and the effect of the DBTM on survival. PATIENTS AND METHODS: We retrospectively evaluated 553 consecutive lung cancer patients who underwent complete lung resection. The patients were classified as DBTM: ≤ 10 mm (group 1), 11 to 20 mm (group 2), and > 20 mm (group 3). RESULTS: We found BSR in eight (1.5%) patients. Six patients were in group 1, and two were in group 2. The difference was found to be statistically significant (p = 0004; groups 1 vs. 3). In multivariable analysis, we observed a trend toward significance for the effect of a DBTM on BSR development (p = 0.1). The DBTM did not significantly affect survival (p = 0.61). The survival of patients who developed BSR was significantly poor compared with those who did not develop BSR (p = 0.001). CONCLUSION: BSR can develop even after complete resection of lung cancer. The DBTM is associated with BSR risk, and the survival of patients who develop BSR is poor.

Relationship between lung adenocarcinoma histological subtype and patient prognosis.

PURPOSE: Lung adenocarcinoma (AC) demonstrates various histological subtypes within the tumour tissue. A panel established jointly by the IASLC, ATS and ERS classified invasive lung ACs based on the predominant histological subtype. We examined the distribution of tumours in lung AC patients according to histological subtype and analysed the effects of this classification on survival. METHODS: The records of patients who had pulmonary resection for lung cancer between January 2000 and December 2009 were reviewed and 226 lung AC patients who fulfilled the inclusion criteria were identified. Histological subtypes of the ACs and their ratios in the tumour tissue were determined. Tumours were classified according to the predominant histological subtype and subsequently graded. The relationship between the predominant histological subtype, grade and survival were analysed. RESULTS: Tumours were predominantly acinar in 99 cases (43.8%), solid in 89 (39.3%), lepidic in 20 (8.8%), and papillary in 11 (4.8%), whereas 7 tumours (3%) were variants of AC. Stage significantly affected survival (p = 0.001); however, the predominant histological subtype had no significant effect. The 5-year survival rate for patients with histologically grade II tumours was 48.6%, whereas that in patients with grade III tumours was 56%. (p = 0.69). CONCLUSION: Invasive lung ACs may be defined by their predominant histological subtype. However, it is not yet possible to conclude that this classification is related to survival.

Squamous cell carcinomas confined to the bronchial wall: the effect of growth patterns.

BACKGROUND: Squamous cell carcinomas confined to the bronchial wall (SCC-CBW) exhibit two distinct patterns of growth: superficially spreading and endobronchial mass lesions. We examined whether differences exist in the histopathological features and prognosis of SCC-CBW exhibiting different growth patterns. MATERIALS AND METHODS: In this study, 37 cases with SCC-CBW were included. Tumors were classified into two groups: superficially spreading squamous cell carcinoma (s-SCC) and nodular squamous cell carcinoma (n-SCC). For each case, the growth pattern, T and N status, lymphovascular and perineural invasions, immunohistochemical expressions of p53 and Ki-67, and survival rates were analyzed. RESULTS: Twenty cases were classified as s-SCC, and 17 cases were classified as n-SCC. There was a significant relationship and correlation between the length of s-SCC in the longitudinal axis and the depth of invasion (p = 0.01, R = 0.557). There was a statistically significant positive relationship between the depth of invasion and the nodal status (N1 involvement) (p < 0.0001, R = 0.71). CONCLUSIONS: SCC-CBW exhibits variable growth patterns. However, despite this variability, there are no biological or histological differences between tumors of different growth patterns, and this variability has very little, if any, effect on survival.

Metachronous lung cancer that presented as bilateral synchronous lung cancer.

Every patient undergoing curative treatment for primary lung cancer is a candidate for metachronous lung cancer, with a reported risk of 5% per year. The majority of cases are stage I patients. Patients who undergo resection for lung cancer should be followed regularly. A metachronous lung cancer that develops as bilateral synchronous lung cancer is very rare.

Primary pulmonary non-Hodgkin's lymphoma: ten cases with a review of the literature.

INTRODUCTION: Primary pulmonary non-Hodgkin's lymphoma (PPNHL) of the lung occurs very rarely. To clarify clinical features, treatment alternatives and outcomes, we evaluated our surgically diagnosed PPNHL cases. MATERIALS AND METHODS: A retrospective review of PPNHL cases from January 2004 to December 2009 was performed. Demographic and clinical data are presented as means or medians. Overall survival was estimated using the Kaplan-Meier method. Survival rates were compared using the log-rank test. A p value < 0.05 was considered significant. RESULTS: Patients were eight males and two females with a median age of 50 years (range, 29-76 years). In 40% of the patients, antigenic stimulation, immune-suppression or auto-immune disease could not been found. All patients were symptomatic at presentation. Surgical procedures were needed to obtain a diagnosis (nine wedge resections and one pneumonectomy). Eight patients had an extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), and two had diffuse large B-cell lymphomas. The patients were treated with observation (pneumonectomy case), chemotherapy (n= 7), and chemotherapy and radiotherapy (n= 1). Five-year survival was 76%. Difference in survival rates of patients with bilateral vs. unilateral disease were not statistically different. CONCLUSIONS: On contrary of the literature, PPNHL can occur with absence of antigenic stimulation, and patients generally have some symptoms. Chemotherapy or surgery can be used to treat PPNHL. Patient survival is good.
