Events that took place in medicine during the 15th, 16th, and 17th centuries signaled the end of the Dark Ages. The Renaissance movement, spreading from Italy across Europe, ended the religious and public prohibitions that had prevented progress in medicine. Pioneer physicians and surgeons who gave their attention to discoveries in anatomy, physiology, and chemistry established the foundations for tumor pathology, surgical oncology, and medical oncology. This review is a summary of their accomplishments.

In vitro studies in mantle cell lymphoma (MCL) cell lines and patient-derived cells have demonstrated synergistic apoptosis with combined rituximab and bortezomib (R-bortezomib) compared with single-agent bortezomib. Therefore, the authors of this report evaluated R-bortezomib in a preclinical model and in a phase 2 clinical trial. ⋯ R-bortezomib had significant activity in patients with relapsed or refractory follicular lymphoma and MCL, although an unexpectedly high incidence of grade 3 neurologic toxicity was a potential limiting factor with this combination.

The objectives of this study were to compare tumor volume and patient weight versus traditional factors of tumor size (greatest dimension) and patient age and to determine which parameters best discriminated outcome among pediatric patients with intermediate-risk rhabdomyosarcoma (RMS). ⋯ The factors that had the strongest association with EFS were tumor volume, patient weight, and histology. On the basis of regression modeling, tumor volume and patient weight were superior predictors of outcome compared with greatest tumor dimension and patient age in children with intermediate-risk RMS. The current results indicated that the prognostic performance of tumor volume and patient weight should be assessed in an independent prospective study.

Central venous catheter (CVC) removal has often been recommended for the treatment of central line-associated bloodstream infections (CLABSIs). However, CVC removal is not always practical in patients with cancer, and changing CVCs with noncoated CVCs over guidewire may result in cross-infection of the new CVC. Therefore, the current matched retrospective cohort study was conducted to evaluate the effectiveness of exchanging infected CVCs for minocycline- and rifampin (MR)-coated CVCs in cancer patients with CLABSIs. ⋯ Exchanging CVCs for MR-coated CVCs in cancer patients with CLABSIs may improve the overall response rate and decrease the risk of mechanical failure, disease recurrence, and infection-related mortality.

Comparative Study
Neoadjuvant therapy is associated with improved survival in resectable pancreatic adenocarcinoma.
Neoadjuvant therapy has been used to improve survival in operable pancreatic cancer. The authors' objective was to compare long-term outcomes in patients receiving neoadjuvant versus adjuvant therapy for resectable pancreatic adenocarcinoma. ⋯ This is the first population-based study to compare neoadjuvant versus adjuvant treatment strategies in resectable pancreatic cancer. Neoadjuvant therapy is associated with a lower rate of lymph node positivity and improved overall survival and should be considered an acceptable alternative to the surgery-first paradigm in operable pancreatic cancer.
