Article Abstract
Background: The role of completion surgery after concurrent radiochemotherapy (CCRC) for advanced cervical cancer remains controversial. Individual predictive factors of CCRC response and survival are mandatory for treatment adaptation and to determine a population who would take interest in completion surgery after CCRC. The aim of this study was to evaluate the ability of biomarkers to predict the response to CCRC.
Patients And Methods: Between 1996 and 2008, in 58 patients with advanced cervical cancer for whom pre-therapeutic cone biopsy was available, we tested several biomarkers (ALDH1, CD44, CD24, IDO, Ki67, P63, CK7, p-Stat3, Foxp3 and IDO).
Results: Residual disease was found in 49.1% of cases (n=26). We found a significant association between progression-free survival and residual disease on completion hysterectomy (p=0.044). Univariate analysis of the different factors showed that negativity for cytokeratin 7 expression was a strong predictor for the presence of residual tumor (p=0.001).
Conclusion: These results are encouraging and CK7 could be used as a predictive factor of response to CCRC.

Background: Carotid artery stenosis is a major cause of stroke. Non-contrast MR angiography (MRA) using time-spatial labeling inversion pulse (Time-SLIP) may offer potential advantages over 3D time-of-flight (TOF)-MRA for simultaneous visualization of carotid, vertebral, and subclavian arteries, but remains uninvestigated.
Purpose: To determine optimal black blood inversion time (TI) for visualizing the carotid and subclavian arteries using three-dimensional (3D) fast field echo (FFE) Time-SLIP MRA, and to compare its image quality with 3D TOF-MRA.

Objective: We hypothesized that anatomic location of metastatic melanoma is associated with the degree of therapeutic response to TVEC.
Summary: TVEC is the first FDA-approved injectable oncolytic virus to treat unresectable stage IIIB-IV metastatic melanoma patients. Previously published real-world outcomes demonstrated a 39% complete response (CR) rate to TVEC.

Background: Salvage surgery (SS) is one of the best treatment options for recurrent oropharyngeal squamous cell carcinoma (OPSCC) after prior definitive radiation.
Methods: A Medline literature search of articles on open (OSS) and transoral robotic surgery (TORS) for the treatment of recurrent OPSCC was performed. Surgical, functional, and oncological outcomes were analyzed and compared.

Purpose: The fourth most common cause of cancer-related deaths in women is cervical cancer. Though treatment of early-stage cervical cancer is often effective, middle and advanced stage cervical cancer is hard to treat and prone to recurrence. We sought to explore the mechanism underlying cervical cancer progression to identify new therapeutic approaches.
