  • Clinical impact of multiple pectus bars on surgical outcomes following pectus excavatum repair

    Oka N., Masai K., Okubo Y., Kaseda K., Hishida T., Asakura K.

    Interdisciplinary Cardiovascular and Thoracic Surgery 39 ( 4 )  2024.10

    　View Summary

    OBJECTIVES: The Nuss procedure, a minimally invasive surgery for pectus excavatum, has undergone various improvements. However, the impact of using multiple bars on thoracic shape changes and surgical outcomes remains unclear. METHODS: We retrospectively evaluated patients who underwent the Nuss procedure for pectus excavatum between August 2014 and September 2021. We divided the patients into 2 groups based on the number of bars placed and identified differences in surgical outcomes and morphological characteristics. RESULTS: A total of 225 patients were evaluated, of whom 132 were classified into the ≤2 bar group (using 1 or 2 bars) and 93 into the ≥3 bar group (using 3 or more bars). There was no difference in the preoperative Haller index [median (interquartile range), 4.59 (3.67–6.16) vs 4.67 (4.12–6.14), P ¼ 0.227], and asymmetric excavatum was more frequently observed in the ≥3 bar group (81% vs 51%, P < 0.001). The preoperative sternal torsion angle was larger in the ≥3 bar group, but no difference was found between the 2 groups postoperatively. The incidence of postoperative complications (≥grade 3) was comparable between groups (10% vs 17%, P ¼ 0.105); however, postoperative pleurisy was more frequently observed in the ≥3 bar group (12% vs 4%, P ¼ 0.021). In univariable and multivariable analyses, ≥3 bar placement was the only risk factor for postoperative pleurisy. CONCLUSIONS: The placement of multiple bars (≥3 bars) is useful for the correction of asymmetric pectus excavatum, but attention should be paid to the potential risk of postoperative pleurisy.

  • Surgically resected sarcomatoid carcinoma of the lung: a nationwide retrospective study in 2010

    　View Summary

    BACKGROUND: Sarcomatoid carcinoma of the lung is a rare histological type of non-small cell lung cancer with a poor prognosis. We aimed to investigate the clinicopathological characteristics and prognostic factors of surgically resected sarcomatoid carcinoma of the lung. METHODS: We retrospectively reviewed 14999 patients who underwent surgical resection for non-small cell lung cancer accumulated by the Japanese Joint Committee of Lung Cancer Registry in 2010. Clinicopathological characteristics and survival were compared between the sarcomatoid carcinoma and other non-small cell cancer groups. The prognostic factors in the sarcomatoid carcinoma group were identified using a multivariate Cox proportional hazard model. RESULTS: Patients with sarcomatoid carcinoma comprised 1.4% of all patients. The sarcomatoid carcinoma group demonstrated a more aggressive pathology with presentation at more advanced stages, requiring more frequent extensive surgical resections. The sarcomatoid carcinoma group had remarkably poorer overall and recurrence-free survival than the other non-small cell lung cancer group. Adjuvant chemotherapy was associated with improved survival for pathological stage II-III sarcomatoid carcinoma cases rather than for pathological stage I disease. In the multivariate analysis, larger tumor size, lymphatic permeation, and no adjuvant chemotherapy were associated with the sarcomatoid carcinoma group's overall and recurrence-free survival. CONCLUSIONS: Surgically resected sarcomatoid carcinoma of the lung has a higher aggressive and metastatic potential and a worse prognosis than other non-small cell lung cancers. Adjuvant chemotherapy, which was associated with enhanced survival in patients with pathological stage II-III of the disease, could be considered for treating patients with pathological stage II-III sarcomatoid carcinoma of the lung.

  • Loeys-Dietz syndrome associated with scoliosis progression after combined Ravitch and Nuss procedure for severe pectus excavatum: A case report

    　View Summary

    <p>Loeys-Dietz syndrome (LDS) is a congenital connective tissue disorder that shares certain typical features with Marfan syndrome. Pectus excavatum is a common skeletal comorbidity in LDS. We report a case of LDS characterized by scoliosis progression following pectus excavatum repair. A 9-year-old boy, who was diagnosed with LDS by genetic tests at the age of 5, was referred to our division for severe pectus excavatum (Haller index: 9.81). He also had mild scoliosis (Cobb angle of 8.5°). The pectus deformity was repaired through a combined Ravitch and Nuss procedure, involving the insertion of two pectus bars beneath the sternum, partially resecting the costal cartilages. Post-surgery, the Haller index reduced to 3.57, but the initial lumbar scoliosis markedly progressed, with the Cobb angle increasing to 34.2°. Treatment with a brace was initiated as scoliosis progressed immediately after the surgery. Scoliosis improved markedly by the 4<sup>th</sup> month post-surgery. In patients with pectus excavatum complicated with scoliosis, it can progress after pectus excavatum repair. In this case, due to the background of tissue fragility associated with LDS, excessive spinal deformity occurred due to pectus excavatum repair.</p>

  • Clinicopathological predictors of postoperative long-term myasthenic status in resected thymoma with myasthenia gravis

    　View Summary

    Purpose: Surgical patients with thymoma and myasthenia gravis (MG) must have their MG status and oncological outcomes critically monitored. We aimed to identify clinicopathological predictors of the postoperative MG status. Methods: We conducted a retrospective review of 40 consecutive surgical patients with MG-related thymomas between 2002 and 2020. The quantitative myasthenia gravis score (QMGS) and Myasthenia Gravis Foundation of America post-intervention status (MGFA-PIS) were used to evaluate postoperative MG status. Results: All patients underwent extended total thymectomy. The most common WHO type was type B2 (32%), while 65% of patients had type B1–B3 and 35% had type A–AB thymomas. Eleven patients (28%) achieved controlled MG status in MGFA-PIS 6 months after surgery. This controlled status was observed more frequently in type A–AB than in B1–B3 (57% vs. 12%, p = 0.007). In a multivariate analysis, WHO type (A–AB or B1–B3) was an independent predictor of worsening episodes of MG based on the QMGS (Type B1–B3, hazard ratio: 3.23, 95% confidence interval: 1.12–9.25). At the last follow-up, 23 patients (58%) achieved controlled MG status. The 5-year overall survival rate of all patients was 93.7%. Conclusion: The WHO type of thymoma is an informative predictor of postoperative MG status in patients with MG-related thymoma.

    　View Summary

    Cryotherapy and cryoimmunotherapy were performed to 1.5cm femoral tumor that originated from Lewis Lung Cancer cell. Histologically, the area of nonviable tumor was significantly increased in size in cryoimmunotherapy group than cryotherapy group (Average: 88% vs 73%). Our data suggest that cryoimmunotherapy is superior than cryotherapy in local control and the most effective route is local administration. On the other hand, there was no difference in the effectiveness of local control between these three immune checkpoint inhibitors.

  • Hemoglobin vesicles ameriolate allograft airway rejection

    　View Summary

    Acute rejection after lung transplantation is the main risk factor for the development of bronchiolitis obliterans (BO). Hemoglobin-vesicles (HbV) have been developed for use as artificial oxygen carriers and this can provide anti-inflammatory effects and may serve to limit tissue injury in airway transplant. Here, we tested the ability of HbV to prevent airway rejection. Tracheal grafts from BALB/c or C57BL/6 were transplanted to C57BL/6 recipients. Experimental groups were treated with HbV. Histopathological evaluation of luminal obliteration was blindly reviewed. Immunohistochemistry and real-time RT-PCR analyses were performed. Allografts treated with HbV revealed a reduction of thickening in epithelial and subepithelial airway layers at day 7 in orthotopic trachea transplantation model compared with allografts treated with vehicle. There was also a concordant decrease in CD3+ lymphocytes and macrophages in HbV treated allografts.
