Coordination and optimization of FDG PET/CT and COVID-19 vaccination; Lessons learned in the early stages of mass vaccination.

As the world embarks on mass vaccination for COVID-19, we are beginning to encounter unintended dilemmas in imaging oncology patients; particularly with regards to FDG PET/CT. In some cases, vaccine-related lymphadenopathy and FDG uptake on PET/CT can mimic cancer and lead to confounding imaging results. These cases where findings overlap with cancer pose a significant dilemma for diagnostic purposes, follow-up, and management leading to possible treatment delays, unnecessary repeat imaging and sampling, and patient anxiety.

Randomized Phase 2 Trial of Pharmacodynamic Separation of Pemetrexed and Intercalated Erlotinib Versus Pemetrexed Alone for Advanced Nonsquamous, Non-small-cell Lung Cancer.

Background: Pharmacodynamic separation of pemetrexed and erlotinib avoids negative cellular interactions and results in antitumor synergy in erlotinib-resistant non-small-cell lung cancer (NSCLC) cells, independent of EGFR (epidermal growth factor receptor) genotype.

Patients And Methods: Patients with platinum-treated metastatic nonsquamous NSCLC were randomly assigned 1:2 to pemetrexed alone (500 mg/m provided intravenously on day 1) or pemetrexed followed by erlotinib (150 mg provided orally once daily on days 2-17) every 21 days. EGFR genotype was centrally confirmed by Sequenom multiplex oncogenotyping assay.

A Phase II Trial of Cetuximab, Gemcitabine, 5-Fluorouracil, and Radiation Therapy in Locally Advanced Nonmetastatic Pancreatic Adenocarcinoma.

Background: Pancreatic cancer is the fourth leading cause of cancer deaths in the United States. A minority of patients present with localized disease and surgical resection still offers patients the only hope for long-term survival. Locally advanced pancreatic cancer is defined as surgically unresectable, but has no evidence of distant metastases.

Phase-I/II study of bortezomib in combination with carboplatin and bevacizumab as first-line therapy in patients with advanced non-small-cell lung cancer.

Background: This study aimed to establish the maximum tolerated dose (MTD) of weekly bortezomib in combination with fixed standard doses of carboplatin and bevacizumab, and to estimate the efficacy (response rate and progression free survival [PFS]) and safety of combination therapy with carboplatin, bortezomib, and bevacizumab as first-line therapy in patients with advanced non-small-cell lung cancer (NSCLC).

Methods: Patients were assigned to three dose levels of weekly bortezomib with the fixed standard doses of carboplatin AUC 6 and bevacizumab (15 mg/kg) every 3 weeks using a standard phase-I design. Bortezomib doses were 1.
