The characteristics and comparison of countries regarding clinical trials for cancer were unknown. The World Health Organization-International Clinical Trials Registry Platform (WHO-ICTRP) are providing data from various countries and releases them generally in a downloadable format. https://www.selleckchem.com/products/skf96365.html We aimed to examine and descriptively identify the number of cancer clinical trials registered in the world and the fundamental characteristics in Asian 4 countries of China, India, Japan and South Korea, focusing on study characteristics, e.g., phase or targeted size, using the WHO-ICTRP.

We extracted information on cancer clinical studies in the ICTRP database on September 20, 2019. Then, we performed a cross-sectional study on the annual number of registered studies and country, registered registry, phase, target sizes and sponsors.

We identified 80,677 cancer clinical studies. The annual number of registered cancer clinical studies significantly increased between 2005 and 2018 (3,172 to 8,156, β =382.2, 95% CI 329.6, 434.8). Among the Asian 4 countries, the numbers of trials were significantly increasing in 2005-2018 (P<0.001). The characteristics on interventional studies for cancer differed in those 4 countries, e.g., the registered registries, phase and sponsors, compared with the US.

This study descriptively clarified an increase and the characteristics of cancer clinical trials in Asian 4 countries. It suggests to take that characteristics into account and select a database or data source discreetly for analysis of clinical trials, according to the purpose of the research and the required data.

Clinically, it can present as unilateral, sometimes painful, increasing breast resistance, or as a hard, irregular mass. Sonography is the most useful diagnostic method for GM evaluation. The only method for definitive diagnosis is the use of biopsy. In histological findings, GM is characterized by non-caseifying granulomas, often associated with microabscess and fistula formation. There is considerable heterogeneity in treatment options; this may explain the high recurrence rate which is close to 50%. Such a high recurrence rate is alarming and proves that current treatments are suboptimal. Two treatment options are discussed worldwide conservative strategies involving drug therapy with corticosteroids versus a surgical approach involving partial or total mastectomy. All conservative treatment options are associated with a high risk of recurrence, and most patients require surgery in the end. Thorough excision of inflammatory tissue is crucial for successful treatment while negative surgical margins are associated with a low recurrence rate. The surgical approach to GM requires sufficient radicality and presumes knowledge in the field of reconstructive breast surgery, similarly to oncosurgical breast conservation operations. However, alternatives to GM treatment with oral steroids may be acceptable for patients concerned about surgery. This article presents six case reports of patients treated at our department.

Damage of the skin and its underlying structures is acommon side effect of radiotherapy. These conditions limit further treatment and dealing with these complications is aroutine practice of clinical oncologist. The majority of the complications are immediate, with aperspective of healing ad integrum within afew weeks. Less frequently, but sometimes with severe manifestations, chronic toxicity occurs belatedly after months, or even many years after irradiation, in form of post-radiation ulcer, for instance with potential of secondary malignant transformation. Regarding surgery, it might be one of the most challenging chronic wounds to treat. In extreme cases, extensive resection of the entire affected area is needed, inevitably ending with demanding reconstruction of the resulting defect.

This case report presents afemale patient with rapidly progressive post-radiation chest wall defect 33 years after the irradiation, when relatively insignificant skin injury occured. Prior to this sudden deterioration, only long-term, non-progressive changes, without acutaneous defect, were described during the dispensarisation. After aprotracted outpatient treatment with unsatisfactory results, when the patient repeatedly refused mastectomy, the condition inevitably led to the complex surgical procedure with necessary cooperation of breast, plastic and thoracic surgeons.

Although changes of the similar severity rarely occur even after many years following the treatment, we havent found such adramatic change of the patientscondition three decades after the therapy with urgency of this type of complex, surgical intervention in current literature.

The purpose of this study was to compare the radiation dose to organs at risk for deep-inspiration breath hold (DIBH) and free-breathing (FB) radiotherapy in patients with lef-sided breast cancer undergoing adjuvant radiotherapy after partial mastectomy. Methods One hundred patients with left-sided breast cancer underwent DIBH and FB planning computed tomography scans, and the 2 techniques were compared. Dose-volume histograms were analyzed for heart, left anterior descending coronary artery (LAD), and left lung. Results Radiation dose to heart, LAD, and left lung was significantly lower for DIBH than for free breathing plans. The median mean heart dose for DIBH technique in comparison with FB was 1.21 Gy, and 3.22 Gy respectively; for LAD, 4.67 versus 24.71 Gy; and for left lung 8.32 Gy versus 9.99 Gy. Conclusion DIBH is an effective technique to reduce cardiac and lung radiation exposure.
