Review
BACKGROUND
Malignant pleural effusion (MPE) is a common and debilitating condition seen in advanced cancer disease, and life-expectancy is short. Symptoms include pain and severe shortness of breath. Current first-line treatment options include pleural drainage using catheters as well as pleurodesis. However, these treatment modalities are often inefficient and patients need repeated procedures. Pressurized IntraThoracic Aerosol Chemotherapy (PITAC) is a minimally invasive procedure, where antineoplastic agents are nebulized under pressure into the pleural space.
CONTENT
We present the preliminary safety, feasibility, and response assessment data for PITAC based on a comprehensive literature review.
SUMMARY
Five retrospective studies reported data on 38 PITACs in 21 patients. Data were heterogeneous and incomplete on several important aspects such as procedure, safety, local effect and long-term outcomes. PITAC seems technically feasible with a low risk of complications and may provide some reduction in MPE in selected cases.
OUTLOOK
PITAC seems feasible, but prospective phase I and II studies are needed to define safety, indications, and efficacy.

During breast cancer recurrence, drug therapy is planned based on the biological characteristics of the primary tumor. However, the mechanisms underlying these changes have not yet been clarified. A 59-year-old woman underwent breast cancer surgery 23 years previously and received postoperative hormone therapy for 2 years. She had abdominal distention and ascites effusion and was diagnosed with carcinomatous peritonitis due to luminal-type breast cancer after ascites puncture. She received up to the fourth line of treatment. Subsequently, pleural effusion was observed and human epidermal growth factor receptor 2 type breast cancer was diagnosed because of pleurodesis. This case suggests that the cell block diagnostic method based on thoracic and ascites fluid cytology is useful not only for confirming the primary tumor but also for diagnosing the biological characteristics of breast cancer. In the treatment of breast cancer recurrence, it is important to plan the treatment, including aggressive re-biopsy of metastases.

Is there a change in the view of treatment for primary spontaneous pneumothorax?: The effect of thoracic CT and autologous blood pleurodesis: a retrospective cohort study.
This study investigated recurrence rates and treatment efficacy based on tomographic findings during a long-term follow-up after primary spontaneous pneumothorax (PSP) treatment. We retrospectively analyzed patients with PSP treated at our hospital between 2003 and 2020. Patients were categorized into 2 groups based on computed tomography (CT) findings: group 1 (no bulla/bleb) and group 2 (bullae-bleb <3 cm). Data on demographics, recurrence, treatment methods, and outcomes were also collected and compared. A total of 251 PSP cases were evaluated, predominantly male (93.6%) with a mean age of 29.23 ± 1.14 years. Most cases (57%) occurred on the right side. Recurrence rates were highest within the first year (77.8%), with the first and second recurrences occurring at rates of 26% and 27.3%, respectively. In group 1 (n = 117), conservative treatment was applied in 15 cases, tube thoracostomy in 81, autologous blood pleurodesis (ABP) in 19, and surgery in 12. Recurrence rates were 46.6%, 21%, 5.3%, and 8.3%, respectively. In group 2 (n = 134), the recurrence rates were 50%, 32.7%, 20%, and 3.1%, respectively (P < .001). No mortality was observed for any patient. The treatment groups included conservative (n = 19), thoracostomy (n = 179), ABP (n = 34), and surgical (n = 44) groups. Recurrence rates were 47.3%, 27.4%, 11.8% (group 1: 5.3%, group 2: 20%, P = .035), and 4.5% (0% vs 6.3%), respectively. ABP effectively reduced recurrence in group 1 PSP patients without bullae or blebs on CT, potentially avoiding surgery. Video-assisted thoracoscopic surgery should be preferred in group 2 cases with bullae or blebs to minimize recurrence. These results underscore the importance of tailoring treatment strategies based on CT findings to optimize PSP management outcomes.

BACKGROUND
Pneumothorax is a non-physiological collection of air in the pleural space. Pneumothoraces can be broadly divided into Primary, Secondary, and Traumatic. Cancer of the lung is a known cause of secondary pneumothorax in both primary and metastatic lesions, however, pneumothorax as the presentation of lung cancer is exceedingly rare. Non-small cell lung carcinoma (NSCLC) has been reported in the literature to present with a pneumothorax, particularly in adeno/squamous cell carcinomas. It is almost completely unheard of for small cell lung carcinoma (SCLC) to present with a pneumothorax.
CASE PRESENTATION
We present the case of a 62-year-old male patient, presenting twice in two months with spontaneous pneumothorax. The initial management involved admission and chest drain insertion. The patient has a past medical history of COPD and a significant smoking history. On the second admission, he underwent a video-assisted thoracoscopic (VATS) bullectomy and talc pleurodesis. The pathology report of the resected specimen confirmed SCLC with extensive infiltration. No gross evidence of metastatic spread was present on CT. Due to the R1 resection and significant risk of recurrence, the management plan included four cycles of adjuvant chemotherapy with carboplatin and etoposide, and radiotherapy as a consideration upon completion.
CONCLUSIONS
Pneumothorax as the presentation of lung cancer imparts a very poor prognosis, however the reasons for this are largely unknown. Furthermore, the mechanisms underlying spontaneous pneumothorax in lung cancer are also not well understood.

Spontaneous pneumothorax is one of the most common conditions encountered in thoracic surgery. This condition can be treated conservatively or surgically based on indications and guidelines. Traditional surgical management includes pleurodesis (mechanical or chemical) in addition to bullectomy if the bullae can be identified. Mechanical pleurodesis is usually performed by surgical pleurectomy or pleural abrasion. In this case report, we present a case of a young patient with spontaneous pneumothorax who needed a surgical intervention. We performed a new, innovative surgical technique for surgical pleurectomy where we used carbon dioxide for dissection of the parietal pleura (capnodissection). This technique may provide similar efficiency to the traditional procedure but with less risk of bleeding and complications.

BACKGROUND
Chylothorax is a seldom encountered complication following lung surgery. However, due to the widespread practice of lung surgery, postoperative complications have inevitably arisen. Chylothorax significantly affects a patient's discharge and recovery. This study investigates the risk factors for postoperative chylothorax at our center and analyzes various treatment modalities and prognostic outcomes.
METHODS
A retrospective analysis was conducted on all postoperative lung resections performed between January 2018 to August 2021 that met the inclusion criteria. Inclusion criteria covered patients undergoing various thoracic surgeries for lung conditions, while exclusion criteria included postoperative referrals for surgeries unrelated to lung tumors.
RESULTS
Postoperative chylothorax occurred in 42 of 5,706 patients after lung surgery. General information and disease-related data of the chylothorax and control group were analyzed by univariate and multivariate analyses. Multivariate analysis showed that serum albumin before surgery [odds ratio (OR) =0.86, 95% confidence interval (CI): 0.81-0.91, P<0.001], γ-glutamyl transferase level before surgery (after logarithmic transformation, OR =1.01, 95% CI: 1.00-1.01, P=0.01), squamous cell carcinoma (OR =2.77, 95% CI: 1.37-5.6, P=0.008), right mediastinal lymph node dissection (OR =3.15, 95% CI: 1.62-6.14, P<0.001) were independent risk factors for postoperative chylothorax. Among the 42 cases of postoperative chylothorax, 26 patients were improved with conservative treatments, and 6 patients were improved with chemical pleurodesis. Eight patients with postoperative chylothorax underwent thoracoscopic thoracic duct ligation. Three patients experienced severe postoperative complications: one was discharged after prolonged treatment, while the remaining two either succumbed or were discharged against medical advice.
CONCLUSIONS
The incidence of chylothorax after lung surgery closely correlates with the intraoperative trauma and nutritional status of patients during the perioperative period. The majority of patients with postoperative chylothorax experienced relief through conservative measures, somatostatin administration, and chemical pleurodesis. Nevertheless, substantial postoperative chylothorax necessitated surgical intervention, involving thoracic duct ligation or drug pleurodesis.

BACKGROUND
Pneumothorax is a rare but serious complication of septic pulmonary embolism (SPE). SPE is a life-threatening disorder wherein infected thrombi bring infarction of the terminal and small caliber parts of the pulmonary vasculature and develop multiple nodular and cavitary lesions. Interventions other than conservative chest tube drainage for pneumothorax due to SPE have rarely been reported. Here, we present a case of bilateral pneumothorax due to SPE treated with intrapleural minocycline pleurodesis.
CASE DESCRIPTION
A 72-year-old male patient previously diagnosed as esophageal carcinoma developed metachronous bilateral pneumothorax while treated for brain metastases. Based on blood cultures and chest computed tomography images, he was diagnosed with pneumothorax secondary to SPE due to methicillin-susceptible bacteremia. Bilateral chest tube drainage was instituted. Continuous air leakage was found bilaterally after chest tube placement. He was treated with broad-spectrum antibiotics based on the susceptibility profile and supportive treatment for sepsis. Approximately 3 weeks later, air leakage significantly reduced. We performed intrapleural minocycline pleurodesis bilaterally to prevent the recurrence of pneumothorax; the left side was firstly treated and the right side was treated 2 weeks later. Both chest tubes were successfully removed two days after procedures. Although the patient finally died of brain metastases 1 month after pleurodesis, he never recurred pneumothorax.
CONCLUSIONS
Intrapleural minocycline pleurodesis may be one of the useful and efficacious options in terms of treating intractable pneumothorax associated with SPE. Intrapleural minocycline pleurodesis could be a consideration for intractable pneumothorax related to SPE.

BACKGROUND
The usefulness of autologous blood pleurodesis for air leak after pulmonary resection is well known; however, factors predicting the therapeutic efficacy are poorly understood. Herein, we aimed to examine the predictors of early autologous blood pleurodesis for air leak following pulmonary resection.
METHODS
Patients who underwent pulmonary resection and autologous blood pleurodesis with thrombin for postoperative air leak between January 2016 and October 2022 were retrospectively analyzed. Patients received 50-100 mL of autologous blood and 20,000 units of thrombin on postoperative days 1-4. If necessary, the same procedure or pleurodesis with other chemical agents was repeated until the air leak stopped. Patients were divided into single-dose and multiple-dose groups based on the number of times pleurodesis had occurred before the air leak stopped and were statistically analyzed. Logistic regression analysis was performed to identify predictors of treatment efficacy.
RESULTS
Of the 922 patients who underwent pulmonary resection, 57 patients (6.2%) were included and divided into single-dose ( = 38) and multiple-dose ( = 19) groups. The amount of air leaks was identified as a significant predictor of multiple dosing, with a cutoff of 60 mL/min, in multivariate logistic regression analyses (odds ratio 1.13, 95% CI 1.03-1.24, = 0.0065). The multiple-dose group showed a significantly higher recurrence of air leak ( = 0.0417).
CONCLUSIONS
The amount of air leaks after pulmonary resection is the only significant factor predicting whether multiple autologous blood pleurodesis is required, and the recurrence rate of pneumothorax is significantly higher in such cases.

Introduction Persistent air leak (PAL) is associated with prolonged hospitalization, high morbidity and increased treatment costs. Conservative treatment consists of observation, chest tube drainage and pleurodesis. Guidelines recommend surgical evaluation if air leak does not respond after 3-5 days. One-way endobronchial valves (EBV) have been proposed as a treatment option for patients with PAL in which surgical treatment is not feasible, high risk or has failed. We aimed to provide a comprehensive overview of reported EBV use for PAL and issue best practice recommendations based on multicenter experience. Methods We conducted a retrospective observational case-series study at four different European academic hospitals and provided best practice recommendations based on our experience. A systematic literature review was performed to summarize the current knowledge on EBV in PAL. Results We enrolled 66 patients, male (66.7%), median age 59.5 years. The most common underlying lung disease was chronic obstructive pulmonary disease (39.4%), and lung cancer (33.3%). The median time between pneumothorax and valve placement was 24.5 days (IQR: 14.0-54.3). Air leak resolved in 40/66 patients (60.6%) within thirty days after endobronchial valve treatment. Concerning safety outcome, no procedure related mortality was reported and complication rate was low (6.1%). 5 patients (7.6%) died in the first 30 days after intervention. Conclusion EBV placement is a treatment option in patients with persistent air leak (PAL). In this multicenter case-series of high risk patients not eligible for lung surgery, we show that EBV placement resulted in air leak resolution in 6 out of 10 patients with a low complication rate. Considering the minimally invasive nature of EBV to treat PAL as opposed to surgery, further research should investigate if EBV treatment should be expanded in low to intermediate risk PAL patients.
