AbstractBackgroundWe hypothesized full‐thickness chest wall resection (FTCWR) with advanced surgical techniques and modern systemic therapy is safe, provides local control, and good overall survival.MethodsRetrospective review of FTCWR (including rib or part of sternum) for breast cancer between 2000 and 2020. Primary endpoints included 90‐day morbidities and all‐cause mortality. Secondary endpoints were loco‐regional and distant recurrence, DFS and overall survival (OS).ResultsA total of 35 patients met the criteria. 34 FTCWR were for recurrence and the median time to chest wall recurrence was 6 years. Tumor subtype was triple‐negative in 51% and the remainder HR+ Her2−. 58% were palliative resections. FTCWR included rib(s) in 89% and portion of sternum in 57%; 94% required reconstruction and 80% were R0 resections. There were no 90‐day mortalities. Overall morbidity was 10/35(28%). 17(49%) patients received neoadjuvant systemic therapy for their recurrence and three received neoadjuvant radiation. Adjuvant treatment included chemotherapy (8), endocrine therapy (3), and both (8). Ten patients (28%) received adjuvant radiation. The Median follow‐up was 31 months and there were 6 (17%) loco‐regional and 7 (20%) distant recurrences. OS was 86% and 67% at 1 and 3 years, respectively.ConclusionFTCWR was associated with low morbidity, mortality, recurrence rates, and good OS. Selective FTCWR is safe and has acceptable short‐term survival rates.

For donation after circulatory death, procurement is performed after the heart has arrested. This technique has been employed and adopted by clinicians to overcome the shortage of available hearts for transplant. Warm ischemia time plays a pivotal role in the survival outcome of the heart recipients. We describe a fast and safe technique to flush the heart during recovery from circulatory death donors in order to shorten the warm ischemia time.

AbstractDespite advancements in local‐regional and systemic therapies, non‐small cell cancer (NSCLC) remains a leading cause of death worldwide. Among those treated with standard‐of‐care modalities, 30–60% experience disease recurrence. Carbon ion radiotherapy (CIRT) is a form of densely ionizing radiotherapy with unique physical and biological advantages over traditional photon and proton modalities. CIRT is expected to have a superior biological impact on tumors, and is believed to be less impacted by the presence of tumor hypoxia or cell cycle state. It also shows highly conformal physical dose deposition due to reduced lateral scattering of the particles, limiting the radiation dose delivered to adjacent organs at risk. To implement CIRT as a viable option in the treatment of NSCLC, technical aspects of treatment delivery – including appropriate beam arrangements, dose calculation algorithms, radiobiological models, and methods of motion management – must be thoroughly investigated. Furthermore, randomized clinical trials comparing CIRT versus traditional radiation modalities must be performed to show the benefits and risks associated with this novel treatment modality. This review discusses the rationale for utilizing CIRT in NSCLC, available clinical data to date, and the potential for future investigations that may pave the path for improving outcomes in those diagnosed with NSCLC.

The coexistence of expiratory central airway collapse and diaphragmatic paralysis presents a diagnostic and treatment challenge. Both entities are underrecognized causes of dyspnea, cough, sputum production, and orthopnea. Optimal treatment must be individualized and is best achieved by a multidisciplinary team. We present a case of a patient with profound functional impairment from dyspnea and hypoxemia due to expiratory central airway collapse, complicated by bronchiectasis from recurrent respiratory infections, and diaphragmatic paralysis.

A 53-year-old male patient was presented to our institution with the clinical picture of biventricular failure. The echocardiogram revealed congenitally corrected transposition of the great arteries, dextrocardia with situs solitus, atrioventricular discordance and ventriculoatrial discordance, severe systemic and mitral valves regurgitation, and severe pulmonary hypertension (mean pulmonary artery pressure: 51 mm Hg). He underwent heart–lung transplant. He was discharged on postoperative day 25 with left ventricular ejection fraction of 60%–65%, and with oxygen independency.

Background. Retained hemothorax (RH) is a common problem in cardiothoracic and trauma surgery. We aimed to determine the optimum agitation technique to enhance thrombus dissolution and drainage and to apply the technique to a porcine-retained hemothorax. Methods. Three agitation techniques were tested: flush irrigation, ultrasound, and vibration. We used the techniques in a benchtop model with tissue plasminogen activator (tPA) and pig hemothorax with tPA. We used the most promising technique vibration in a pig hemothorax without tPA. Statistics. We used 2-sample t tests for each comparison and Cohen d tests to calculate effect size (ES). Results. In the benchtop model, mean drainages in the agitation group and control group and the ES were flush irrigation, 42%, 28%, and 2.91 ( P = .10); ultrasound, 35%, 27%, and .76 ( P = .30); and vibration, 28%, 19%, and 1.14 ( P = .04). In the pig hemothorax with tPA, mean drainages and the ES of each agitation technique compared with control (58%) were flush irrigation, 80% and 1.14 ( P = .37); ultrasound, 80% and 2.11 ( P = .17); and vibration, 95% and 3.98 ( P = .06). In the pig hemothorax model without tPA, mean drainages of the vibration technique and control group were 50% and 43% (ES = .29; P = .65). Discussion. In vitro studies suggested flush irrigation had the greatest effect, whereas only vibration was significantly different vs the respective controls. In vivo with tPA, vibration showed promising but not statistically significant results. Results of in vivo experiments without tPA were negative. Conclusion. Agitation techniques, in combination with tPA, may enhance drainage of hemothorax.
