High Dose Rate Interstitial Brachytherapy With Three Dimensional Printing Template for Recurrent Gynecologic Tumors
Condition: Cervical Cancer Intervention: Sponsor: Peking University Third Hospital Recruiting
mande Jin-Xiong She Molecular biomarkers that can predict survival and therapeutic outcome are still lacking for cervical cancer. Here we measured a panel of 19 serum proteins in sera from 565 patients with stage II or III cervical cancer and identified 10 proteins that have an impact on disease specific survival (DSS) (Hazzard’s ratio; HR = 1.51–2.1). Surprisingly, all ten proteins are implicated in senescence-associated secreted phenotype (SASP), a hallmark of cellular senescence. Machine learning using Ridge regression of these SASP proteins can robustly stratify patients with high SASP, which ...
The aim of this work was to analyze the exposure rates measured in the proximity of patients who underwent prostate low-dose-rate brachytherapy with I-125 implant. Effective doses to relatives and to population were computed to estimate the time to reach radioprotection dose constraints.
High dose-rate (HDR) brachytherapy (BT) is commonly used to treat prostate and cervical cancer by irradiating the target volume using dedicated applicators and/or catheters. BT offers sharp dose gradients which may lead to decreased dose to organs at risk compared to external beam radiotherapy.[1,2] Image-guided implant reconstruction has become standard practice, using medical imaging such as CT, MR or ultrasound acquired before treatment planning.[3,4] After reconstructing the applicator and/or interstitial catheters, a treatment plan is created using the target and organ at risk delineations by optimizing dwell times in...
Minimally invasive surgery (MIS) decreases postoperative morbidity after radical hysterectomy (RH) for early-stage cervical cancer. However, a randomized trial and large retrospective data question its safety after observing lower rates of survival than open surgery [1,2]. The causes of this higher recurrence rate are not definitely established but may result from cancer exposure to peritoneum during vaginal section and cancerous-cells spillage enhanced by pneumoperitoneum or uterine manipulator.
Abstract •PIVOTALboost evaluates benefits/toxicity of pelvic node RT and focal boost dose escalation.•Unfavourable intermediate/high risk and bulky local disease are most likely to benefit.•Functional MRI imaging is used to select patients for different types of dose escalation.•HDR brachytherapy or focal dose escalation with IMRT are used as options.•Training and support is provided to reduce variations of contouring and radiotherapy planning.•The trial is recruiting patients in 38 radiotherapy centres through the UK.

CONCLUSION: Prostate cancer treatment choices differ substantially between men diagnosed in private and public health services in Victoria. These differences are not explained by disease severity or comorbidity. PMID: 32996611 [PubMed - as supplied by publisher]
Conclusion: To the best of our knowledge, this is the first report and analysis of the most cited articles on cervical cancer radiotherapy. This bibliographic study presents the history of technological development in external radiation therapy and brachytherapy. Brachytherapy is an indispensable part of radiotherapy for cervical cancer. The International Journal of Radiation Oncology Biology Physics is the journal with the most publications related to cervical cancer radiotherapy.
Mature results from randomised trials of external beam radiotherapy (EBRT) show that biochemical control of disease improves with increasing radiation dose [1 –4]. High-dose-rate afterloading brachytherapy (HDR-BT) can deliver a high, localised radiation dose to the prostate with excellent biochemical control of disease and has advantages over external beam radiotherapy (EBRT) because of its ability to overcome problems of organ movement, which confound the external beam techniques used [5–7]despite modern image guided approaches.
CONCLUSION: At 12 years there remains a significant improvement in RFS after EBRT + HDR-BTb; both treatments were equitoxic for severe late urinary and bowel events and urethral strictures. PMID: 33011207 [PubMed - as supplied by publisher]
Authors: Singh MP, Chauhan AS, Rai B, Ghoshal S, Prinja S Abstract INTRODUCTION: Cervical cancer is a major public health problem in India leading to high economic burden, which is disproportionately borne by the patients as out-of-pocket expenditure (OOPE). Several publicly financed health insurance schemes (PFHIs) in India cover the treatment for cervical cancer. However, the provider payment rates for health benefit packages (HBP) under these PFHIs are not based on scientific evidence. We undertook this study to estimate the cost of services provided for treatment of cervical cancer and cost of the package...
