Compact proton therapy for fight against cancer

The future face of modern-day anti-cancer therapy based on charged particles like protons could potentially involve using laser accelerators. However, these facilities will need to be reduced in terms of both size and cost compared to conventional ones. A medical physicist is the first to present a new design for the entire complex machine – from the accelerator to the radiation site. In the process, he has successfully cut the facility's size in half.

[Guardian] Researchers are unanimous that talc or talcum powder can cause lung, ovarian, stomach and endometrial (uterine) cancers. They said talc consisting of asbestos is generally accepted as being able to cause cancer if it is inhaled or/and used regularly in the genital area. Evidence on asbestos-free talc is however less clear.

Could a simple blood test catch cancer before symptoms appear?Nicola Davis goes beyond the hype and investigates the future of blood diagnostics and cancerA blood test that could detect cancer earlier than current methods has long been a dream of oncologists. The hope is that these “liquid biopsies” could save countless lives by diagnosing cancer before symptoms show. They’re less invasive, quicker and easier than what is available now.However, this area of research has been plagued with hype. This happened most notably when a Silicon Valley startup –Theranos– allegedlyduped investors out of h...

Publication date: Available online 20 March 2019Source: Urology Case ReportsAuthor(s): Fumio Ishizaki, Ryo Maruyama, Kazutoshi Yamana, Takashi Kasahara, Tsutomu Nishiyama, Yoshihiko TomitaAbstractWe herein report an unusual case of brain metastasis from prostate cancer during androgen deprivation therapy and post-docetaxel and definitive local therapy. The brain metastasis was surgically resected followed by Whole-brain radiation therapy. Postoperatively, his PSA again decreased to an undetectable level and remained undetectable with no evidence of new or recurrent disease.

ABSTRACT Objectives: To ascertain the opinions of North American genitourinary (GU) experts regarding inclusion of technologies such as prostate - specific membrane antigen (PSMA) and C – 11 choline positron emission tomography (PET) into routine practice. Materials and Methods: A survey was distributed to North American GU experts. Questions pertained to the role of PSMA and C – 11 PET in PCa management. Participants were categorized as “ supporters ” or “ opponents ” of incorporation of novel imaging techniques. Opinions were correlated with practice patterns. Results: Response rate wa...

Conclusion: There is a great histopathological variation of initial GS versus reviewed GS. There is also a better correlation of reviewed GS and post - surgical GS than with initial GS. The second opinion by an uropathologist improves diagnosis and should be advised for better therapeutic decision.

Conclusion: Length and location of the PSM and the Gleason score detected in the PSM region could not predict bi ochemical recurrence according to the results of this present study. However high preoperative PSA value is an independent prognostic factor for biochemical recurrence.
