[Redo Operation for Mediastinal Tumor].

Masaomi Yamane, Shinichi Toyooka

Kyobu geka. The Japanese journal of thoracic surgery 74 ( 10 ) 839 - 844 2021.9

Language：Japanese Publishing type：Research paper (scientific journal)

The mediastinum contains large blood vessels, airways, and spinal cord, which are anatomically important parts of the human body because they survive by injury, obstruction, and compression, and are involved in activities of daily living( ADL). Therefore, even benign tumors have been indicated for aggressive surgical intervention. Dissection procedures from these anatomically important structures is extremely risky and difficult in reoperation for recurrence of mediastinal tumors, so careful consideration and attention must be paid to the surgical indications and methods. In this paper, we have described the points to be noted and points regarding the reoperation of mediastinal tumors with some review of the literature, including our own cases.

International journal of clinical oncology 26 ( 8 ) 1450 - 1460 2021.8

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: The association between sarcopenia and prognosis in patients with locally advanced non-small cell lung cancer (NSCLC) undergoing trimodality therapy, consisting of preoperative concurrent chemoradiotherapy and surgery, has not been reported. Therefore, we aimed to investigate the association of sarcopenia and fat mass with prognosis after trimodality therapy. METHODS: To assess sarcopenia, the psoas muscle mass was measured. Using computed tomography data, including third lumbar vertebra level images, psoas muscle mass and visceral and subcutaneous fat mass were measured. Additionally, body mass indices, and visceral/subcutaneous fat ratio, obtained by dividing the visceral fat index by the subcutaneous fat index, were calculated. We investigated the relationship between these parameters and overall survival. RESULTS: Ninety-nine eligible patients were included. In the univariate analysis, age, clinical stage, tumor location, psoas muscle index, and visceral/subcutaneous fat ratio were significant prognostic factors for overall survival (P = 0.008, P = 0.04, P = 0.04, P = 0.02, and P = 0.02, respectively). In the multivariate analysis, age and psoas muscle index were significant prognostic factors for overall survival (P = 0.01 and P = 0.03, respectively). The 5-year overall survival rates for the high and low psoas muscle index groups were 79.6% [95% confidence interval (CI), 67.1-94.5%] and 66.2% (95% CI, 54.1-81.1%), respectively; whereas, the 10-year overall survival rates were 61.9% (95% CI, 42.0-91.4%) and 25.3% (95% CI, 8.6-74.2%), respectively. CONCLUSION: Sarcopenia was related to poor overall survival in patients with locally advanced NSCLC undergoing trimodality therapy. Assessment of body composition prior to treatment may provide important information for formulating rational therapeutic strategies.

An incomplete interlobar fissure makes thoracoscopic lobectomy difficult and is predictive of morbidity after thoracoscopic lobectomy. This report demonstrates the robot-assisted thoracoscopic (RATS) lobectomy technique for patients with severe incomplete interlobar fissures. A fissureless approach was chosen for pulmonary resection. Near-infrared fluorescence imaging with intravenous indocyanine green (ICG) was used to detect the interlobar line after transection of the bronchus, pulmonary artery and vein. Interlobar fissure was identified and divided by robotic staplers. This combined technique using ICG and fissureless lobectomy made RATS lobectomy safe for patients with severe incomplete interlobar fissures.

PURPOSE: Decreased irisin levels may be associated with the development of emphysema. Similarly, emphysematous changes may develop in patients with chronic lung allograft dysfunction (CLAD) after living-donor lobar lung transplantation (LDLLT). We investigated the severity of emphysematous changes and the relationship between irisin levels and CLAD after bilateral LDLLT and cadaveric lung transplantation (CLT). METHODS: The subjects of this retrospective study were 59 recipients of bilateral LDLLT (n = 31) or CLT (n = 28), divided into a non-CLAD group (n = 41), a LDLLT-CLAD group (n = 11), and a CLT-CLAD group (n = 7). We compared the severity of emphysematous changes, the skeletal muscle mass, and the plasma irisin levels among the groups. RESULTS: The emphysematous changes were significantly more severe in the LDLLT-CLAD and CLT-CLAD groups (p = 0.046 and 0.036), especially in patients with bronchiolitis obliterans syndrome (BOS), than in the non-CLAD group. Although the skeletal muscle mass was similar in all the groups, the plasma irisin levels were significantly lower in the LDLLT-CLAD group (p = 0.022), especially in the patients with BOS after LDLLT, than in the non-CLAD group. CONCLUSION: Emphysematous changes and lower levels of plasma irisin were associated with CLAD, especially in patients with BOS, after bilateral LDLLT.

Lung transplantation for bronchiectasis due to hyper-immunoglobulin E syndrome. International journal

Language：English

Hyper-immunoglobulin E syndrome (HIES) is one of the primary immunodeficiencies characterized by recurrent staphylococcal skin and lung infections that result in lung destruction and critically diminished pulmonary function. Despite the lack of definitive treatment, there have been no reports of successful lung transplantation (LTx) for HIES patients. We report the case of a 42-year-old female HIES patient with progressive bronchiectasis whose pulmonary infection was controlled prior to transplantation and subsequent LTx was uneventful. LTx may be feasible in HIES if the patient is immunologically stable preoperatively, and peri-operative infections, especially Aspergillus infections, are well-controlled.

Language：English Publishing type：Research paper (scientific journal)

BACKGROUND: Trimodality therapy is a treatment option for patients with locally advanced non-small cell lung cancer (LA-NSCLC). Thoracic radiation has both early (radiation pneumonitis) and late (chronic lung injury [CLI]) adverse effects on the lung. While CLI is expected to result in various problems in long-term survivors, these manifestations have not been precisely investigated. METHODS: We enrolled 112 LA-NSCLC patients who had received induction chemoradiotherapy followed by surgery, and then undergone follow-up computed tomography (CT) every 6 months for greater than 1 year. All chest CT images were reviewed to evaluate any injury of the pulmonary parenchyma. RESULTS: CLI at 1 year after surgery and its progression were observed in 94 (84%) and 38 (34%) patients, respectively. Progressive lung fibrosis as the first manifestation of CLI progression was most frequent after right middle and lower lobectomy. Cavity formation was the subsequent manifestation after progressive lung fibrosis , and chronic infection was the final stage of CLI. The cumulative rate of chronic infection was 76.4% at 10 years in patients with cavity formation. Ten patients with chronic infection included 7 cases of pulmonary aspergillosis and 2 cases of cavity infections with methicillin-resistant Staphylococcus aureus or Stenotrophomonas maltophilia. Among them, 4 patients required surgical interventions including completion pneumonectomy or fenestration. CONCLUSIONS: CLI is a common incidence after trimodality therapy for LA-NSCLC. CLI frequently results in cavity formation, which is a precursor of highly refractory chronic infections requiring surgical intervention. Appropriate management needs to be established for CLI developing after trimodality therapy.
