Interdisciplinary consensus statement on indication and application of a hydrogel spacer for prostate radiotherapy based on experience in more than 250 patients

Background Dose escalated intensity-modulated radiation treatment (IMRT with radiation doses ≥ 76 Gy) is a highly effective, curative treatment option for localized prostate cancer. Biochemical control is directly related to radiation dose with a dose effect per each additional Gy. 1 For example, escalation from 70 to 80 Gy is connected with a 15% increase in PSA control. This dose effect is described for all risk groups. However, an increased radiation dose is also associated with rising levels of grade ≥ 2 acute and chronic toxicity. 1 Lower

The mysterious relation between inflammation and prostate cancer

responses, and urine reflux [ 5 , 10 , 15 ]. The persistence of these factors is able to contribute to chronic prostatic inflammation. Prostate cancer (PC) is the second common cancer among American men. The role of inflammation or infection remains unclear in different cancer sites and the prostate. Recent studies in different areas, such as epidemiology, histopathology, and molecular pathology, give emerging evidence of the possible role of prostatic inflammation as an important factor involved in PC initiation and progression [ 16 , 17 , 18 ]. Inflammation is

The high-risk HPV infection and urinary system tumor

these studies has resulted in the ambiguity in the correlation between high-risk HPV infection and urinary system tumors. This article describes the progress in the study on the relationship between high-risk HPV infection and tumors of the urinary system. 1 Relationship between high-risk HPV infection and tumors of the urinary system 1.1 High-risk HPV infection and prostate cancer Studies have suggested that HPV infection, especially the high-risk type, is highly detectable in prostate carcinoma tissue. This characteristic indicates that HPV infection has a
