Controlled ovarian stimulation therapy as a potential risk for the development and progression of renal cell carcinomas: A case report and literature review.

Mol Clin Oncol 2021 Jul 23;15(1):140. Epub 2021 May 23.

The Yale Larynx Laboratory, Department of Surgery, Yale School of Medicine, New Haven, CT 06510, USA.

Renal Cell Carcinoma (RCC) is the most common type of cancer in the kidney and is mostly asymptomatic. Previous studies have supported the important role of sex hormones in RCC pathophysiology and that targeted hormone receptor therapy, such as estrogen receptor targeting, is a promising treatment strategy. However, to the best of our knowledge, it remains unknown whether hormonal therapy, such as controlled ovarian stimulation for fertilization, serves a role in the development and progression of RCC.

Effects of Epstein-Barr Virus Infection on the Risk and Prognosis of Primary Laryngeal Squamous Cell Carcinoma: A Hospital-Based Case-Control Study in Taiwan.

Cancers (Basel) 2021 Apr 6;13(7). Epub 2021 Apr 6.

Faculty of Medicine, Chang Gung University, Taoyuan City 33302, Taiwan.

Vocal-cord Only vs. Complete Laryngeal radiation (VOCAL): a randomized multicentric Bayesian phase II trial.

BMC Cancer 2021 Apr 22;21(1):446. Epub 2021 Apr 22.

Radiation Oncology Department, Western University, London, Ontario, Canada.

Background: Radiotherapy, along with laser surgery, is considered a standard treatment option for patients with early glottic squamous cell cancer (SCC). Historically, patients have received complete larynx radiotherapy (CL-RT) due to fear of swallowing and respiratory laryngeal motion and this remains the standard approach in many academic institutions. Local control (LC) rates with CL-RT have been excellent, however this treatment can carry significant toxicities include adverse voice and swallowing outcomes, along with increased long-term risk of cerebrovascular morbidity.

Squamous Cell Carcinoma Mimicking Neck Paraganglioma on 68Ga-DOTATATE PET/CT.

Clin Nucl Med 2021 Jul;46(7):e368-e370

From the Departments of Nuclear Medicine.

Abstract: Somatostatin receptor (SSTR) imaging with 68Ga-labeled somatostatin analogs has been used for many tumors with high SSTR expression. Increased uptake mostly depends on the SSTR status of tumors; however, false-positive uptake can be demonstrated in benign diseases or other malignancies because of the increased SSTR expression. We present a case of a 50-year-old man with increased SSTR activity on cervical lesion located in internal jugular chain in 68Ga-DOTATATE PET/CT, which was performed for suspicion of paraganglioma.
