Diagnostic Usefulness of Combination of Diffusion-weighted Imaging and T2WI, Including Apparent Diffusion Coefficient in Breast Lesions

Conclusion Combining DWI, T2WI, and ADC values provides increased accuracy for differentiation between benign and malignant lesions, compared with DCE-MRI. A lower ADC value was associated with a higher histologic grade cancer.

Prostate cancer is the leading cause of cancer treatment –related years lived with disability for men worldwide.1 This has driven a disruptive change in management of favorable-risk prostate cancer such that nearly all National Comprehensive Cancer Network (NCCN) very low-risk patients are recommended conservative management rather than radical therapy. 2 Simultaneously, at the other end of the risk spectrum, treatment intensification with more potent systemic therapies has been the subject of recent trials for men with higher-risk disease (eg, NCT02772588).

The authors' letter and translational research work support the question posed in the review1,2: Are we at the tipping point for the era of real-time radiation therapy? The research by Dahele and Verbakel adds additional clinical evidence that real-time 3-dimensional image guided radiation therapy (3D IGRT) can be performed on standard-equipped cancer radiation therapy (RT) systems. Indeed, had it been published or known to us before we wrote the review, their clinical translation of markerless spine tracking3 would have been included as a fourth real-time 3D IGRT implementation on standard-equipped systems.

Multiple randomized studies have demonstrated that breast-conserving therapy (partial mastectomy plus whole breast radiation) can yield survival outcomes equivalent to those of mastectomy (1). However, newer population-based data suggest that breast cancer –specific survival and overall survival with breast-conserving therapy may actually be better than those with mastectomy (2-8). How is this possible? How can removal of the breast yield outcomes inferior to those of a therapy that leaves most of the breast intact and where in-breast failures are r eported to occur in approximately 5% to 10% of patients at 10 y...

In the world of cancer care, Halstedian paradigms for radical surgery have evolved toward organ preservation strategies without compromising the probability of cure. As such, clinicians have increasingly turned their focus toward minimizing the stigmata of treatment, with patient-centered outcomes having greater influence on decision making. Today, patients are typically able to preserve much of their functional anatomy and cosmesis. For example, selected patients with head and neck cancers are routinely offered a strategy of larynx preservation with upfront radiation therapy and chemotherapy, reserving a more morbid total...

Given the high-grade epidural spinal cord compression, we would recommend urgent surgical decompression (1). Separation surgery for metastatic renal cell carcinoma is challenging given its highly vascular nature. As such, provided that the patient is not acutely symptomatic from spinal cord compression or overt mechanical instability, we would perform preoperative embolization of the segmental arterial feeders to improve hemostasis and visualization of the neural elements during the operation. Surgery would include a right costotransverse approach to tumor resection with likely sacrifice of the right T7 and possibly T8 ner...

A 66-year-old ex-smoker presented with metastatic renal cell cancer with lytic lesions in the left femur, T8, and a 1.5-cm lesion in the right lung. A biopsy from the femur confirmed clear cell renal cell cancer; the lung lesion could not be biopsied safely. The patient underwent a radical nephrectomy (pathologically staged as pT3a). He commenced sunitinib, which was stopped owing to severe hypertension, followed by everolimus, stopped after 8 cycles owing to muscle cramping. Repeat imaging demonstrated resolution of the lung nodule but progression in the left femur, T8, and new disease in the anterior right 10th rib and left humerus.

MicroRNA‑506‑3p reverses gefitinib resistance in non‑small cell lung cancer by targeting Yes‑associated protein 1. Mol Med Rep. 2018 Nov 29;: Authors: Zhu J, Tao L, Jin L Abstract Epidermal growth factor receptor‑tyrosine kinase inhibitors, such as gefitinib, have been found to be clinically effective in the treatment of patients with non‑small cell lung cancer (NSCLC). However, the therapeutic effect of gefitinib is often limited by the development of gefitinib resistance. MicroRNAs (miRNAs), a group of small non‑coding RNAs, have been demonstrated to be frequently dysregulated in human ...

MEK inhibitor enhanced the antitumor effect of oxaliplatin and 5‑fluorouracil in MEK1 Q56P‑mutant colorectal cancer cells. Mol Med Rep. 2018 Dec 07;: Authors: Jing C, Li H, Du Y, Cao H, Liu S, Wang Z, Ma R, Feng J, Wu J Abstract Mitogen‑activated protein kinase kinase (MEK) small molecule inhibitors have been investigated in preclinical or clinical trials for the treatment of cancer. In the present study the genetic test results of 120 patients with colorectal cancer (CRC) were screened and the mutation rate of MEK1 was identified to be 1.67%. MEK inhibition by U0126 significantly decreased ...
