Introduction: Stage classification is an important underpinning of management in patients with cancer and rests on a combination of three components-T for tumor extent, N for nodal involvement, and M for distant metastases. This article details the revision of the N and the M components of thymic epithelial tumors for the ninth edition of the TNM classification of malignant tumors proposed by the Thymic Domain of the International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee.
Methods: The N and M components of the eighth edition staging system were verified by a large international collaborative data source through a data-driven analysis.
The annual Eastern Canadian Gastrointestinal Cancer Consensus Conference 2023 was held in Quebec City, Quebec 2-4 February 2023. The purpose of the conference was to develop consensus statements on emerging and evolving treatment paradigms. Participants included Canadian medical oncologists, radiation oncologists, pathologists and surgical oncologists from across Ontario, Quebec, and the Atlantic provinces.

The TNM stage classification system was published as a result of a joint project from the International Association for the Study of Lung Cancer and the International Thymic Malignancy Interest Group for the eighth edition of the American Joint Commission on Cancer and the Union for International Cancer Control stage classification system. The Thymic Domain of the Staging and Prognostic Factors Committee of the International Association for the Study of Lung Cancer received the mandate to make proposals for the ninth edition of the TNM stage classification.

The Thymic Domain of the Staging and Prognostic Factors Committee of the International Association for the Study of Lung Cancer, composed of multispecialty international experts, was charged to develop proposals for the ninth edition. This article outlines the proposed definitions for the T, the N, and the M components and their combination into stage groups.

The International Thymic Malignancy Interest Group created the first map for thymic epithelial malignancies in conjunction with the eighth edition of the TNM classification, representing the first official TNM classification of thymic epithelial malignancies. The map was based on clinical experience and published studies, but it was largely empirical because of limited available data.

The Thymic Domain of the Staging and Prognostics Factor Committee of the International Association for the Study of Lung Cancer developed a new database with the purpose to make proposals for the ninth edition stage classification system. This article outlines the proposed definitions for the T categories for the ninth edition TNM stage classification of thymic malignancies.

Methods And Materials: A retrospective chart review was conducted for all patients treated with HDREB for malignant airway disease between 2010 and 2019 at a single institution. Most patients had a prescription of 14 Gy in two fractions given a week apart.
Purpose: Uncontrolled studies suggest that the addition of high-dose-rate intraluminal brachytherapy (HDRIB) to external beam radiation therapy (EBRT) may improve palliation for patients with advanced non-small cell lung cancer (NSCLC). The purpose of this study was to evaluate the potential clinical benefit of adding HDRIB to EBRT in a multicenter randomized trial.
Methods And Materials: Patients with symptomatic stage III or IV NSCLC with endobronchial disease were randomized to EBRT (20 Gy in 5 daily fractions over 1 week or 30 Gy in 10 daily fractions over 2 weeks) or the same EBRT plus HDRIB (14 Gy in 2 fractions separated by 1 week).
Background: Thymomas are characterized by a low tumor mutation burden and a paucity of actionable mutations. Clinical behavior can vary from relatively indolent to very aggressive and impact survival. Platinum-based chemotherapy is the primary treatment modality for inoperable disease and is palliative in intent.

Methods: This systematic review was developed by Ontario Health (Cancer Care Ontario)'s Program in Evidence-Based Care and by the Lung Cancer Disease Site Group.
Introduction: The aim of this guideline was to provide recommendations for the most effective therapy for patients with thymic epithelial tumors, including thymoma, thymic carcinoma, and thymic neuroendocrine tumors (NETs). This guideline is intended to be used by all health care professionals managing patients with thymic epithelial tumors.
Methods: The guideline was developed by Ontario Health (Cancer Care Ontario)'s Program in Evidence-Based Care and by the Lung Cancer Disease Site Group through a systematic review of the evidence, expert consensus, and formal internal and external reviews.
Thymic epithelial tumors are presently staged using a consistent TNM classification developed by the International Association for the Study of Lung Cancer (IASLC) and approved by the Union for International Cancer Control and the American Joint Committee on Cancer. The stage classification is incorporated in the eight edition of the TNM classification of thoracic malignancies. The IASLC Staging and Prognostic Factors Committee (SPFC)-Thymic Domain (TD) is in charge for the next (ninth) edition expected in 2024.

Purpose: To evaluate a novel navigation system for breast brachytherapy, based on ultrasound (US)-guided catheter needle implantations followed by electromagnetic (EM) tracking of catheter paths.
Methods: Breast phantoms were produced, containing US-visible tumors. Ultrasound was used to localize the tumor pose and volume within the phantom, followed by planning an optimal catheter pattern through the tumor using navigation software.
The 9th International Thymic Malignancy Interest Group's (ITMIG) Annual Meeting was held in Seoul, South Korea in October 2018, and in this article, we discuss three of the cases presented and review the radiology imaging and pathology slides. The first two cases involve thymic carcinoma: the first reviews systemic therapy recommendations for non-resectable recurrence and the second case the optimal treatment recommendations after incomplete resection. The third case discusses treatment recommendations for recurrent thymoma after complete resection.

Furthermore, these studies are usually based on pathology or surgical databases and, therefore, miss many lesions that did not undergo biopsy or resection. Our aim was to identify the distribution of lesions in the mediastinum in a large international, multi-institutional cohort.

Methods: A 50-item, web-based questionnaire was circulated among the members of the major thymic organizations worldwide from September to December 2018. The survey consisted of six sections (general information; overall perception of the TNM system; pretreatment staging; T category; N category; and perioperative treatments).
The International Thymic Malignancy Interest Group (ITMIG) has periodic tumor board meetings to discuss challenging cases. The case of a pediatric thymoma from the April 2018 meeting is discussed in this article. Radiology imaging and pathology slides are reviewed.

Optimal regional management in breast cancer patients has yet to be established. In patients who are clinically node-negative, but sentinel lymph node biopsy (SLNB)-positive, the treatment paradigm has shifted toward the de-escalation of further axillary management. In patients with 2 or fewer positive sentinel nodes, the standard of practice has shifted away from complete axillary lymph node dissection (ALND) as a result of the ACOSOG Z0011 trial.

Previously, conventional RT was offered; however, newer techniques such as stereotactic body RT (SBRT) have become available. The objective of the present systematic review was to investigate the effectiveness of RT with curative intent in patients with early-stage medically inoperable NSCLC.
