Article Synopsis
  • The study aims to assess how the size of the primary tumor in T3 N0-3M0 supraglottic cancers affects overall survival (OS) and disease-free survival (DFS) for patients treated with intensity-modulated radiotherapy (IMRT).
  • This retrospective cohort analysis involved 239 patients from Canadian cancer centers, measuring tumor volume via imaging and employing survival analysis methods.
  • Results indicate that larger primary tumor volume correlates with worse OS and DFS, suggesting that patients with significant tumor sizes might benefit more from surgical intervention like laryngectomy followed by radiotherapy.*

Human papillomavirus-associated oropharyngeal squamous cell carcinoma (OPSCC) is increasingly prevalent. Despite the overall more favorable outcome, the observed heterogeneous treatment response within this patient group highlights the need for additional means to prognosticate and guide clinical decision-making. Promising prediction models using radiomics from primary OPSCC have been derived.

Importance: The association of primary tumor volume with outcomes in T3 glottic cancers treated with radiotherapy with concurrent chemotherapy remains unclear, with some evidence suggesting worse locoregional control in larger tumors.

Objective: To evaluate the association of primary tumor volume with oncologic outcomes in patients with T3 N0-N3 M0 glottic cancer treated with primary (chemo)radiotherapy in a large multi-institutional study.

Design, Setting, And Participants: This multi-institutional retrospective cohort study involved 7 Canadian cancer centers from 2002 to 2018.

NTRK gene fusions are rare oncogenic driver mutations that can be found in a broad range of neoplasms. In secretory carcinoma (SC), gene fusion is seen in a majority of the cases and represents a druggable target for patients with advanced disease in the absence of a currently accepted standard of care. In our case, we describe a patient with recurrent, metastatic SC treated with first line entrectinib with clinically meaningful, durable ongoing response after 49 months.
