Article Abstract
Purpose/objective(s): T4 locally advanced squamous cell cancers of the head and neck (SCCHN) with bone and cartilage invasion (BCI) traditionally have been treated with resection followed up with chemoradiotherapy (CRT). Because the organ preservation trials, more patients with BCI, as well as those with soft tissue invasion (STI), have been treated with definitive CRT. This is a review of our experience.
Materials/methods: We performed a retrospective review of patients who underwent definitive CRT or radical resection followed up with postoperative CRT for T4N0-3M0 locally advanced SCCHN. We analyzed outcomes based on STI/BCI and types of treatment. Radiotherapy doses ranged from 59.4 to 72 Gy. Concurrent chemotherapy was platinum based in all CRT patients.
Results: From 1995 to 2006, 101 patients with locally advanced SCCHN were treated definitively. Of these, 51 had STI and 50 had BCI. Of the 51 patients with STI, 42 were treated with CRT, 5 patients were treated with resection followed by CRT, and 4 patients were treated with radiotherapy alone. Of the 50 patients with BCI, 26 patients were treated with CRT, 20 patients were treated with radical resection followed by radiotherapy or CRT, and 4 patients were treated with radiotherapy alone. Five-year local-regional control was 51% and 43% for STI and BCI patients treated with CRT, respectively, and 44% for BCI treated with radical resection. Five-year overall survival was 23%, 51%, and 28% for STI treated with CRT, BCI treated with CRT, and BCI treated with radical resection. Outcomes were not statistically different between these groups.
Conclusions: This study suggests similar outcomes for CRT or resection followed up with chemoradiotherapy for patients with locally advanced SCCHN with BCI. Concurrent CRT may be viable alternative to upfront resection in these patients. Further studies should be performed to validate these provocative findings.

Introduction: Herpes encephalitis is known to affect patients undergoing brain radiotherapy, but early diagnosis and treatment, the foremost determinants of disease outcome, remain challenging in this patient population. This can be due to attribution of symptoms to the brain tumor and radiation side effects, as well as patients' atypical clinical presentation. Here we sought to highlight pearls and pitfalls in the clinical course and diagnostic workup which may facilitate timely diagnosis and improve disease outcome.

Surface receptor-targeted Protein-based nanocarriers for drug delivery: Advances in cancer therapy.

Significant progress has been made in cancer therapy with protein-based nanocarriers targeted directly to surface receptors for drug delivery. The nanocarriers are a potentially effective solution for the potential drawbacks of traditional chemotherapy, such as lack of specificity, side effects, and development resistance. Peptides as nanocarriers have been designed based on their biocompatible, biodegradable, and versatile functions to deliver therapeutic agents into cancer cells, reduce systemic toxicity, and maximize therapy efficacy through utilizing targeted ligands such as antibodies, amino acids, vitamins, and other small molecules onto protein-based nanocarriers and thus ensuring that drugs selectively accumulate in the cancer cells instead of healthy organs/drug release at a target site without effects on normal cells, which inherently caused less systemic toxicity/off-target effect.

Background: Patients with Crohn's disease face an elevated risk of colorectal cancer, in part due to underlying chronic inflammation. Biologic therapy is the mainstay of medical treatment; however, the impact of treatment on colorectal cancer-related outcomes remains unclear.
Objective: To investigate the association between prior exposure to biologic treatment and colorectal cancer-related outcomes in patients with underlying Crohn's disease.
