Cytogenetic and fluorescence in situ hybridization analysis of a thymoma revealed the presence of an abnormal clone with a karyotype 46,XY,r(6)(p2?q35?).ish r(6)(p2?q35?)(WCP6+,dJ476O18-,dJ62I11-, PAC59C23+,PAC57H24-),der(21)t(6;21)(p25;q22)(dJ62I11+,cosC9a1-). Histologically, the tumor was encapsulated and classified as thymoma type AB (World Health Organization classification) or mixed thymoma (Muller-Hermelink classification), composed of well-formed lobules with sharp demarcation of both the spindly type A and lymphocyte-rich type B components. This finding, together with literature data, strongly suggests that terminal deletion of the short arm of chromosome 6 is a recurrent aberration in thymoma.

Cardiac Exposure Related to Adjuvant Radiotherapy in Patients Affected by Thymoma: A Dosimetric Comparison of Photon or Proton Intensity-Modulated Therapy.
Cancers (Basel)
January 2025
Radiotherapy and Radiosurgery Department, IRCCS Humanitas Research Hospital, Via Manzoni 56, 20089 Milan, Italy.
Background: Radiotherapy for thymoma is delivered post-operatively in selected cases. Given the particular location of the thymic bed and the excellent prognosis, late cardiac toxicities may be an issue. The purpose of this retrospective dosimetric study is to investigate whether intensity-modulated proton beam therapy (IMPT) compared to photon therapy could better spare cardiac substructures, given prespecified dose constraints.

Background: Neuroendocrine tumors of the thymus (NETT) are rare and malignant tumors that arise in the anterior mediastinum. These tumors can exhibit aggressive behavior and may involve surrounding critical structures, such as the superior vena cava. This case contributes to the literature by presenting a recurrent thymic carcinoma with invasion of major blood vessels, including the superior vena cava, and the complexities involved in its surgical management.

From the Department of Nuclear Medicine.
We report the case of a 71-year-old woman with recurrence of type B3 thymoma in which the diagnostic accuracy has benefited considerably from the additional use of [68Ga]FAPI PET/CT when compared with the standard [18F]FDG PET. [68Ga]FAPI PET/CT confirmed the known lesions with higher lesion-to-background ratio and additionally identified a previously undetected lesion near the FDG-avid apex of the heart. This case demonstrates a potential superiority of [68Ga]FAPI PET/CT in patients suffering from thymoma as detection of local recurrence close to metabolically active organs (ie, liver, heart) is improved.

. The optimal surgical approach for thymoma resection is still an object of debate. The increasing experience in robotic-assisted thoracic surgery (RATS) has led to the progressive affirmation of this technique as a valid alternative to Sternotomy, Thoracotomy and Video-Assisted Thoracic Surgery (VATS) in this setting.

Introduction And Importance: Thymoma is the most common primary anterior mediastinal tumor in adults. Invasive thymomas infiltrate organs adjacent to the mediastinal pleura, including the lungs, great vessels, heart, pericardium, and diaphragm. Complete resection of invasive thymoma leads to a better prognosis.
