Salvage surgery using simultaneous clamshell thoracotomy with median sternotomy for mediastinal growing teratoma syndrome.

ABSTRACT: This report describes the case of a 17-year-old man who developed mediastinal growing teratoma syndrome following two cycles of chemotherapy, after an initial diagnosis of primary mediastinal nonseminomatous germ cell tumor. The large, rapidly-growing mediastinal tumor was completely resected in conjunction with right pneumonectomy, using simultaneous clamshell thoracotomy and median sternotomy. The salvage surgery with perioperative management involved in mediastinal growing teratoma syndrome is presented here. KEY POINTS: Significant findings of the study The diagnosis and surgical management are challenging for patients with mediastinal growing teratoma syndrome. Nevertheless, with proper operative planning, favorable outcomes can be attained with complete resection despite the characteristic rapid growth and massive size of these neoplasms. What this study adds In spite of postoperative sternal dehiscence, we believe that a simultaneous clamshell thoracotomy with median sternotomy approach remains a viable option for an extremely large mediastinal growing teratoma, when tumor size prevents safe resection using other approaches due to limited visualization.

Project description:BackgroundThe esophagus has no serosa; therefore, esophageal cancer may quickly invade its adjacent organs. In recent years, reports of conversion surgery (CS) and salvage surgery (SS) have described resection of esophageal cancer previously considered unresectable, with the addition of intensive preoperative chemotherapy or chemoradiotherapy. Currently, there is no established method for determining whether tumor excision is possible. Additionally, differences in surgical approaches between facilities may influence outcome after resection. However, the option for resection is considered a significant factor in determining a patient's prognosis.MethodsPatients who were diagnosed with advanced-stage (T3 or higher) squamous cell carcinoma of the esophagus and subsequently underwent resection with CS or SS were included in the study. Resection was performed through a small thoracotomy using a thoracoscope. Clinicopathologic factors, such as complete resection rate (R0) and prognosis, were investigated.ResultsA total of 49 surgeries were conducted: 39 CS and 10 SS cases. The male-to-female ratio was 37:12. R0:R1:R2 equals 42:3:4, and the R0 resection rate was 85.7%. The 5-year survival rates for CS and SS cases were 69.2% and 32.1%, respectively. The 5-year survival rates for R0, R1, and R2 resections were 63.4%, 0.0%, and 25.0%, and those for R0 and R1 + 2 resections were 63.4% and 14.3%, respectively, indicating that the prognosis for R0 resection cases was significantly better (P = 0.001 and P = 0.001, respectively). Regarding chemotherapy for CS, 29 patients received 5-FU and cisplatin therapy, whereas 10 patients received 5-FU, cisplatin, and docetaxel (DCF) therapy. After 2015, the ratio of DCF was significantly high, and the R0 resection rate was 100% in patients who received DCF therapy.ConclusionsIn this study, a satisfactory R0 rate was achieved using the magnifying effect of the thoracoscope while ensuring safety during thoracotomy.Trial registrationThis was a single-center cohort study wherein clinical data were retrospectively registered. This study was approved by the Chiba Cancer Center review board (H29-262). All procedures adhered to the ethical standards of the responsible committee on human experimentation and the Helsinki Declaration of 1964 and its later amendments.
