A biochemical definition of cure after brachytherapy for prostate cancer
Since post-treatment PSA values were first introduced into clinical practice in the 1980s, clinicians have grappled with interpretation of these values. Two consensus conferences, ASTRO in 1996 [1] and Phoenix in 2005 [2], defined biochemical failure after external beam radiotherapy (EBRT), but neither included data from patients treated with androgen deprivation therapy (ADT) or brachytherapy [3]. Neither consensus conference attempted to define cure and neither definition is readily comparable...

Ultrahypofractionated vs hypofractionated and conventionally fractionated radiation therapy for localized prostate cancer: a systematic review and meta-analysis of phase III randomized trials
In 2019, approximately 174,650 men will be diagnosed with prostate cancer in the United States.[1] Recent estimates have demonstrated that number to be more than twofold higher in Europe.[2] The Prostate Testing for Cancer and Treatment (ProtecT) trial suggested that conventionally fractionated radiation therapy (CFRT) (1.8-2 Gy, 5 days per week, for 8-9 weeks to a total dose of 70-81 Gy) offers similar oncologic outcomes with improved quality of life when compared to radical prostatectomy.[3,4]...

Although we previously reported that weekly prostate SABR had better bowel and urinary QOL compared to EOD, the updated results show no difference in late toxicity, QOL, BF, or PSA kinetics. Patients should be counselled that QW SABR reduces short-term toxicity compared to QW SABR.

With the current Covid 19 pandemic, healthcare systems are severely strained1–3. So far, infection and severe complications have been less common in children4. Nevertheless the pandemic is expected to have an impact on the capacity to deliver paediatric radiotherapy, particularly where general anaesthesia is required, due toshortages ofpersonnel,protective equipment, ventilatorsand machine time, as well as coping infected children and families5,6. Sudden shortage of resources may also occur during...

Implications for cancer care in iran during COVID-19 pandemic
As the COVID-19 pandemic surges, concerns grow over serious health conditions. Since the healthcare resources are highly stretched taking care of the COVID-19 patients, other parts of the Iranian healthcare system are critically influenced. Cancer care is specifically facing innumerable challenges in our country, putting the clinical decision-makers in a parlous risk of mismanagement, ranging from the risk of the exposure to COVID-19 to the harm caused by the delayed treatment. Regarding the therapies,...

Accelerated hypofractionated radiotherapy with concurrent full dose chemotherapy for locally advanced non-small cell lung cancer: a phase I/II study
The use of chemotherapy (CHT) concomitant with (radiotherapy) RT in locally advanced non-small cell lung cancer (NSCLC) has been demonstrated to prolong overall survival (OS) compared with sequential RT–CHT or with RT alone [1,2]. In one study, radiation dose escalation up to 74 Gy/37 fractions in concomitant RT–CHT was detrimental for OS compared with the standard 60 Gy /30 fractions [3]. A combination of several factors may explain the counterintuitive harmful effects of the higher radiation dose...

Feasibility of 3D tracking and adaptation of VMAT based on VMAT-CT
Volumetric modulated arc therapy (VMAT) is an advanced technique that can deliver highly conformal radiation dose and reduce overall treatment time. However, due to high degree of complexity and dose gradients, the requirement of delivery accuracy has increased for VMAT. Pre-treatment quality assurance (QA) and image guidance can detect certain errors [1–4], but they are not sufficient to detect intra-fractional movement of the patient, change of patient’s anatomy or the errors during VMAT, and image...

The recent outbreak of the novel Coronavirus SARS-CoV-2 has dramatically hit many hospitals, involving an overwhelming number of patients. Most of them suffered a change in their diagnostic and therapeutic program. Cancer patients represent one of the most fragile groups due to their compromised clinical conditions exasperated by age, comorbidities, immunosuppression status and by the number of hospital visits requested for the radiation therapy course.

Universal Do-Not-Resuscitate Orders, Social Worth, and Life-Years: Opposing Discriminatory Approaches to the Allocation of Resources During the COVID-19 Pandemic and Other Health System Catastrophes
These authors share thoughts about discriminatory approaches to the allocation of resources during health care catastrophes, such as the COVID-19 pandemic. They argue that, although prioritization of resources is critical, fairness requires giving each patient his or her due based on clinical criteria applied to the individual rather than assumptions that favor or disfavor groups.

A new, simplified, arthroscopic technique to reposition and suture a displaced anterior disc in the temporomandibular joint
There are several techniques for arthroscopic discopexy reported in the literature. The most widespread is the McCain technique,1 which is technically simple but has some disadvantages. Zhang et al2 proposed modifications to it, which improved the technique, but made it extremely complex and therefore not a feasible option for most surgeons. We aim to describe a new technique that allows for repositioning of the disc, is similar to the modified technique,2 but technically simpler than the original.
