The benefit of adjuvant radiotherapy (ART) for extrahepatic cholangiocarcinoma (EHCC) and gallbladder carcinoma (GBC) is unclear, with conflicting results from nonrandomized studies. We reported a meta-analysis to determine the impact of adjuvant radiotherapy on survival. PubMed, EMBASE, Cochrane Library and CNKI databases were searched to identify clinical trials of postoperative ART versus no radiotherapy for EHCC and GBC. The obtained data were analyzed using RevMan 5.3 and Stata 14.0 statistical software. Differences between two groups were estimated by calculating the odds ratio (OR) and 95% confidence interval (CI). A total of 21 clinical trials involving 1465 EHCC and GBC patients were selected according to the inclusion and exclusion criteria and included in this meta-analysis. The meta-analysis showed the following: The 5-year overall survival (OS) rate was higher in the ART group than in the no radiotherapy group (OR = 0.63; 95% CI = 0.50-0.81, p = 0.0002). The 5-year OS rate was significantly

MONDAY, Aug. 12, 2019 (HealthDay News) - Adjuvant radiotherapy after radical prostatectomy compared with surgery alone may prolong biochemical recurrence-free survival in patients with locally advanced prostate cancer, according to a study published online July 29 in European Urology.. Greetta Hackman, of the University of Helsinki, and colleagues recruited a total of 250 patients at eight hospitals in Finland who had either pT2 prostate cancer with positive margins or pT3a, pN0, M0 cancer regardless of margins. Patients were randomly assigned to an adjuvant radiotherapy or observation group. The adjuvant radiotherapy group received a radiation dose of 66.6 Gy. The median follow-up time was 9.3 years for patients in the adjuvant radiotherapy group and 8.6 years for patients in the observation group.. The researchers found that the group receiving adjuvant radiotherapy had a higher 10-year recurrence-free survival rate than the observation group (82 versus 61 percent; hazard ratio, 0.26; 95 ...

Whats more, a separate, but related study, found that urologists were less likely than radiation oncologists to recommend adjuvant radiation therapy or to believe it improves overall survival.. There has been question over whether administering adjuvant radiation therapy after removing the prostate is an appropriate course of action because of associated toxicities, risk of overtreatment and costs, even with data supporting its benefits to overall survival, but a new decision analysis published online in the Annals of Oncology on June 9 found that the procedure is a practical option for patients.. This work demonstrates that adjuvant radiation therapy is a cost-effective strategy for selected patients after prostatectomy, said Laura Pizzi, PharmD, Associate Professor at the Jefferson School of Pharmacy, and senior author of the study. It is typical for cancer treatments to provide clinical benefit at a cost; however, the cost per success that we reported for adjuvant radiation therapy is on ...

We investigated postmastectomy radiotherapy (RT) use and evaluated clinicopathologic and treatment factors influencing RT use in Korean women with pT1-2N1 breast cancer. We identified women diagnosed with pT1-2N1 breast cancer between 1994 and 2009 using the Korean Breast Cancer Registry. Factors associated with RT use were evaluated using logistic regression analysis. The median follow-up was 95 months. Of the 6196 women, 11.9% underwent ...

The delivery of cancer treatment following local treatment with surgery is referred to as adjuvant therapy and may include chemotherapy, radiation therapy, hormonal therapy and/or biologic therapy. The goal of adjuvant radiation therapy is to eradicate any remaining cancer cells after surgery. Adjuvant radiation therapy may consist of brachytherapy and/or external beam radiation.. Stage I Uterine Cancer: Although it is still being evaluated in clinical trials, many patients with stage IB and IC uterine cancer are often treated with adjuvant radiation therapy. When the uterus is surgically removed, the cut ends of the vagina are surgically sewn together forming a vaginal cuff. The vaginal cuff is a common site of local cancer recurrence following treatment with surgery alone. Women with stage I uterine cancer who receive treatment with surgery and postoperative radiation therapy have a 5-year survival of 80-90% and a local cancer recurrence rate of only 4-8%.. A large clinical trial that ...

The American Society for Radiation Oncology (ASTRO) has issued a new guideline, The Role of Postoperative Radiation Therapy for Endometrial Cancer: An ASTRO Evidence-Based Guideline, that details the use of adjuvant radiation therapy in the treatment of endometrial cancer. The guidelines executive summary is published in the May-June 2014 issue of Practical Radiation Oncology.. ASTROs Guidelines Panel of 17 leading gynecologic specialists compiled and reviewed extensive data from 330 studies from MEDLINE, EMBASE and the Specialized Register of the Cochrane Gynaecological Cancer Review Group published from 1980 to 2011. The data population selected for the guideline was defined as women of all races, age 18 or older, with stage I to IV endometrial cancer of any histologic type or grade. The studies included patients who underwent a hysterectomy followed by no adjuvant therapy, or pelvic and/or vaginal brachytherapy with or without systemic chemotherapy.. The panel identified five key ...

Purpose: The optimal number of axillary nodes to be resected is controversial. This large series investigated the effect of surgery with or without adjuvant radiotherapy among node-negative breast cancer patients in relation to the number of nodes examined. Methods and materials: Node-negative patients from the Saskatchewan registry of 1981-1995 were studied. Because nodal status may be more reliable with more number of nodes examined, we analyzed T1-2 age | 90 patients with | 10 nodes examined treated with surgery alone (Group A_S, n = 509) vs. surgery and adjuvant radiotherapy (Group A_S+R, n = 342); and T1-2 age | 90 patients with | or = 10 nodes examined treated with surgery alone (Group B_S, n = 902) vs. surgery and adjuvant radiotherapy (Group B_S+R, n = 596). Results: For the two radiotherapy groups, patients with | 10 nodes (Group A_S+R) vs. | or = 10 nodes (Group B_S+R), there was no difference in overall survival (p = 0.14). In the two nonradiotherapy groups (A_S and B_S), there is a

Patterns of recurrence were studied for correlation with radiation fields. Potential clinical and treatment variables were tested for possible association with local-regional control (LRC), disease-free survival (DFS), and overall survival (OS).TAt 5, 10, and 15 years, OS rates were 57%, 36%, and 27%, respectively; DFS rates were 46%, 37%, and 34%; and LRC rates were 87%, 87%, and 87%. No clinical or treatment variables were associated with OS or DFS. The use of supplemental axillary radiation (SART) (p = 0.012) and pathologic N stage (p = 0.053) were associated with improved LRC. ...

Neoadjuvant radiotherapy (neoRT) used in tumor treatments is aimed at increasing regional tumor control and individual overall survival. traditional parameters studied such as for example hypoxia vessel matrix and density remodeling. The analysis of tumor-related swelling and immunity shows an elevated circulating NK cell percentage pursuing neoRT when compared with non irradiated mice. Rays treatment and medical procedures were put on tumor-bearing NOD/SCID mice Then. In the lack of NK cells neoRT seems to boost lung metastatic dissemination as compared to non irradiated tumor-bearing mice. Altogether our data demonstrate that the neoRT schedule and the ST timing affect metastasis formation in a pre-clinical model and points out the potential role of NK cells. These findings highlight the importance to cautiously tailor the optimal window for ST following RT. = 0.58) in control group and 0.003 (= 0.93) and 0.67 (= 0.08) in mice subjected to early and late ST respectively).

OUTLINE: This is a randomized, open-label study. Patients are randomized to 1 of 2 treatment arms.. All patients undergo apheresis for the collection of peripheral blood monocytes that are cultured with interleukin-4 and sargramostim (GM-CSF) to produce dendritic cells. The dendritic cells are infected with a recombinant adenoviral vector containing the wild-type p53 gene.. Patients receive doxorubicin IV and cyclophosphamide IV every 2 weeks for 8 weeks (4 courses) followed 2 weeks later by paclitaxel IV every 2 weeks for 8 weeks (4 courses). Patients with stage III disease then undergo surgery. Three weeks after completion of paclitaxel (or after surgery for patients with stage III disease), patients undergo radiotherapy once daily for 6.5 weeks. Patients are then receive vaccine therapy as per the arm to which they were randomized.. ...

In this manuscript, we show that treatment with low doses of fractionated radiotherapy leads to upregulation of PD-L1 expression on tumor cells secondary to CD8+ T-cell production of IFNγ. In models of melanoma, colorectal, and breast cancer, we demonstrate that the efficacy of radiotherapy can be enhanced through combination with αPD-L1 mAb, leading to the generation of memory immunity in LTS mice capable of protecting against tumor recurrence. Furthermore, our data reveal that dose scheduling may be critical for outcome with concurrent but not sequential therapy effective at improving local tumor control and survival.. Recent clinical trials have begun to evaluate blockade of the PD-1/PD-L1 axis with encouraging responses observed in multiple disease settings with mAb targeted against both PD-1 and PD-L1 (18-20, 24, 25). Despite this, combination approaches may be required to improve response rates and to generate durable antitumor immunity. We and others have demonstrated the potential to ...

The function of postoperative radiotherapy (PORT) in patients with completely resected pathologically N2 (pN2) non-small cell lung cancer (NSCLC) remains controversial due to a lack of prospective studies. The present study aimed to evaluate the efficacy of PORT in completely resected pN2 NSCLC when using modern radiation techniques, and to determine the associations between clinicopathological factors and PORT and survival rates. Following patient selection, 246 out of 269 consecutive patients with pN2 NSCLC were enrolled in the present study, with 88 patients having received postoperative chemotherapy (POCT) and PORT, 90 having received adjuvant chemotherapy, 1 having received adjuvant radiotherapy and the remaining 67 having received no adjuvant therapy ...

Three sensitivity analyses were performed. First, a second matching step was performed in which two controls were selected for each case, where possible using a nearest neighbor and caliper metric. Controls needed to have propensity scores within 0.1 of the case to be selected. Thirty-eight of the 39 cases had at least one control using this method and for 36 cases two controls could be selected. The average difference between case and control propensity adjuvant RT was 0.008 (range 0.00003-0.095). A second sensitivity analysis was performed to guard against immortal time bias. In order to mitigate the possibility of this effect, cases known not to have undergone adjuvant RT have been screened for suitable follow-up without a recurrence (local or regional recurrence, metastatic failure, and/or death) to ensure that if adjuvant RT had been prescribed as part of the multi-modality treatment regimen, that it would have been initiated. Three months was selected as the mandatory follow-up time. One ...

Full-dose intra-operative radiotherapy with electrons (ELIOT) during breast-conserving surgery: experience with 1246 cases U Veronesi1, R Orecchia 2,7, A Lui

Radiotherapy has been considered a local modality and outcomes have emphasized local and regional control of tumors. Recent data suggests that radiotherapy may activate the immune system and the combination of radiation therapy and immune therapies may have the potential to improve both local and distant control of tumor deposits. Below we review principals underlying the concepts of combining both modalities.

The initial literature search identified 7,453 studies. We excluded 1,931 duplicates and excluded 5,504 studies by title screening because they did not meet the eligibility criteria. Eighteen randomized controlled trials were selected for full-text review, and 15 papers were discarded; 6 trials compared surgery alone and surgery plus postoperative radiation, 2 compared surgery alone and preoperative longcourse radiation plus surgery, 6 compared surgery alone and preoperative short-course radiation and surgery, and one was long-term results of a previous reported trial. Three randomized trials comparing preoperative CRT with postoperative CRT in resectable stage II-III rectal cancer were finally identified; Park et al. [9] in 2011, Roh et al. [10] in 2009, and Sauer et al. [5] in 2004 (Fig. 1). All patients in both preoperative and postoperative arms received conventionally fractionated radiotherapy of 50-54 Gy with 1.8-2 Gy per fraction for 5-6 weeks. Concurrent chemotherapy of intravenous ...

The major goal of radiation treatment is to kill meningioma tumor cells while minimizing damage to surrounding normal brain tissue. Radiation therapy for meningiomas involves externally beaming from a machine high energy X-rays at the tumor site (known as external beam radiation). There are variations of radiation therapy and the type chosen is based on factors used for determining treatment options discussed at the beginning of this section (size, location, symptoms, age and health of patient), as well as the extent of tumor removal and the WHO grade of the meningioma.. Radiation therapy is often prescribed following surgery where there has been incomplete tumor removal, regardless of the tumor grade. When used as such, the treatment is called adjuvant radiotherapy, meaning it is used in addition to the primary treatment option of surgery in order to increase the chances of a more positive outcome. In the case of benign meningiomas that were incompletely removed, its use has been effective in ...

Radiotherapy to the breast can sometimes lead to long-term side effects. A few months after radiotherapy some women develop breathlessness (due to the effect of radiotherapy on the lung). This can usually be treated with a short course of steroids. In the longer term there may be some weakness of the ribs in the irradiated area, which makes them more likely to fracture than normal. If you have radiotherapy to your underarm (axilla) there is a very small risk of developing late side effects such as nerve pain, tingling, and weakness or numbness in the arm and hand (peripheral neuropathy ...

Doctors give unbiased, helpful information on indications, contra-indications, benefits, and complications: Dr. Ho on chemo savvy: Definitely you should get an adjuvant radiation therapy following mastectomy. As per- chemo- if you get chemo first before surgery and unfortunately the response is only marginal- that indicates that your cancer is likely is resistant to chemo.So, adding more chemo post mastetcomy doubtfully will give you any benefit. Is this er+ or er-? If this is er+- then you should get aromatase inhibitor.

automatic roll changer: Ferris-wheel type device (usually) which stores 2 to 12 perforated paper rolls and changes them automatically, usually in the sequence in which they are placed on the changer mechanism (or, if desired, a particular roll can be selected). Several variations occur, including a device made by Philipps which incorporates extra roll-holding sections which hang below the basic revolver mechanism; and a 10-roll cartridge-type changer unit, called a 10-roll magazine, by Popper & Co., but constructed on different principles from those used in a standard revolver- or magazine-type mechanism. Perhaps the most sophisticated roll changing device was one developed by Hupfeld, which, in its most elegant form, consisted of two 10-roll changers arranged side by side (for a total selection of 20 rolls) and equipped with a device for selecting a desired roll from a distant control panel or wallbox. In America, the Wurlitzer Automatic Roll Changer (capitalized in Wurlitzers usage) achieved ...
