A Retrospective Analysis of the Diagnosis of Gastroenteropancreatic Neuroendocrine Tumors at The Ottawa Hospital Cancer Center over the Last Decade Including COVID-19 Pandemic Period.

Introduction: The incidence of neuroendocrine tumors (NETs) is rising. Our objective was to assess trends in gastroenteropancreatic (GEP)-NETs diagnosis (June 2010 to June 2021) at TOHCC and to explore whether early COVID-19 pandemic data impacted these trends.

Methods: This was a single-center retrospective chart review of data collected from June 2010 to June 2021.

Small Bowel Adenocarcinoma: 10-Year Experience in a Cancer Center-The Ottawa Hospital (TOH).

(1) Small bowel adenocarcinoma (SBA) is one of the predominant primary small bowel cancers that has a dismal outcome. We aim to report 10 years of experience in SBA management at a regional cancer centre in Canada.; (2) We retrospectively analysed clinical and pathological data of patients diagnosed with an SBA between 2011 and 2021 at the Ottawa Hospital (TOH), Ottawa, Canada.

Study of Post-COVID-19 Syndrome in Saudi Arabia.

Background Post-COVID-19 syndrome may be predisposed by organ damage as a complication of COVID-19. Patients may experience persistent symptoms after recovering from their initial illness. Objectives To identify manifestations and predisposing factors for post-COVID-19 syndrome in Saudi Arabia.

Unusual Synchronous Association of Solid Tumors with Hematological Malignancies in Multiple Primary Cancers: Case Series and Literature Review.

The incidence of synchronous multiple primary malignancies (MPMs), which include both solid and hematological malignancy, is considered very rare. In addition, the involvement of sites such as brain, thyroid, and breast are among the least reported in such complex conditions. Here we report five different types of solid tumors including glioblastoma multiforme, thyroid papillary carcinoma, breast invasive ductal carcinoma, colon cancer, and gastric adenocarcinoma that were associated with synchronous five different hematological malignancies in the form of T-cell lymphoblastic non-Hodgkin lymphoma (NHL), nodal marginal zone NHL, diffuse large B-cell NHL, Hodgkin lymphoma, and gastric mucosa-associated lymphoid tissue marginal zone NHL, respectively.

Diagnostic and Therapeutic Challenges Associated with the Rare Cardiac Metastasis Complicating Rectal Adenocarcinoma.

Colorectal cancer (CRC) is one of the most common malignancies in the world. It typically metastasizes to the lymph nodes, liver or lungs. Cardiac involvement is considered the least likely metastatic complication of malignant tumors including CRC.

Testicular Mixed Germ Cell Tumor Combined with Malignant Transformation to Chondrosarcoma: A Very Rare and Aggressive Disease.

BACKGROUND Testicular mixed germ cell tumors (GCTs) represent a spectrum of malignancies that differ in terms of histopathology, clinical complications, and overall outcome. A variety of aggressive combinations containing different histological types have been described among such testicular tumors. However, a histopathology characterized by a combination of teratoma and choriocarcinoma, as seen in this case, in which the teratomatous component shows a secondary transformation to chondrosarcoma, is considered very rare.
