Purpose: To analyze the time-dose relationship for local control of disease in patients with advanced head and neck neoplasms enrolled in two sequential Phase I dose escalation studies in which concomitant chemotherapy and radiotherapy were delivered on an alternate week schedule (i.e., 1 week of concomitant therapy alternated with 1 week of rest). Cancer Prevention and Control Research Network. Using three methods of analysis, the loss of control consistently approximated 1% per day of treatment prolongation beyond 30 days, although analysis of sta … The Effect of Treatment Duration in the Local Control of Cervix Cancer Radiother Oncol. Of 36 patients with T1 + T2 lesions who had tumorectomy prior to radiotherapy, incomplete excision of tumor was demonstrated on microscopic examination in 18. … The data, which were shared during the 2020 Society of Urologic Oncology Annual Meeting, support the Mohs procedure as a feasible approach for long-term local control in this patient population. Prospective, randomized clinical trials have demonstrated that the alternatives of mastectomy or conservative surgery plus radiation therapy provide e local control of primary cancer of the tongue. This study reports the treatment and local control of advanced breast cancer with a giant ulcer. Purpose: A prospective randomized trial was conducted to determine whether the addition of concurrent cisplatin to preoperative or definitive radiation therapy in patients with muscle-invasive bladder cancer improved local control or survival. Regional control was 77% for node positive patients and 96% for N0 patients (p = 0.01). Username *. The study analyses an impact of volumetric nodal involvement (Total Nodal Volume – TNV) on Local Control of the primary tumour (LTC) in radiotherapy for oral cavity and oropharyngeal cancer. From 1973 to 1980, 701 patients with breast cancer measuring less than 2 cm in pathological diameter and with no palpable axillary lymph nodes were randomized to Halsted mastectomy (349) or to "quadrantectomy" with axillary dissection and radiotherapy to the ipsilateral breast tissue (QUART) (352). Widmark et al. Many prognostic factors may directly and/or indirectly affect the local control, including radiotherapy interruption (RTI), which is a significant independent factor in the local control of lung cancer , laryngeal cancer and NPC [12, 13] using two dimensional radiotherapy. Here, we evaluated the effect of the durvalumab on local control in comparison with the clinical result of patients treated with CCRT … Stage I non-small cell lung cancer patients who were treated with stereotactic radiotherapy between 2005 and 2009 at our hospital were enrolled in this study. The aim of this study was to investigate whether local control after radiotherapy in laryngeal cancer is associated with the ATM‐associated DDR pathway activity.

The local control rate of metastatic lung tumors after SBRT of 48 Gy in four fractions was significantly worse in our series (25% at 2 years) compared with the series of Norihisa et al. These data confirm the comparable effectiveness of TARGIT-IORT versus EBRT in terms of cancer control, with no difference in local recurrence-free survival, invasive local recurrence-free survival, mastectomy-free survival, or distant disease-free survival for at least 12 years from randomisation . The Cancer Prevention and Control Research Network (CPCRN) external icon is a national network of academic, public health, and community partners who work together to reduce the burden of cancer, especially among those disproportionately affected. You can also follow (e) Science News on Twitter or Facebook Cancer control is a term often used by the media, medical centers, and organizations like the American Cancer Society. Patients treated to greater than 7000 cGy do not show a demonstrable improvement in local control, but do show an increase in complications. The duration of BMA use until evaluation of local control in BMA alone and BMA + RT groups were 5 (range, 2–43) and 4 … Local response was classified according to modifications of the Response Evaluation Criteria in Solid Tumors. Rectal cancer is an area where radiation sensitization has been extensively addressed, primarily to improve local control and the major morbidities associated with local pelvic failure after combined-modality therapy. It's free! Can local therapy alter the clinical course of patients with prostate cancer? Local control for clinical stage I non-small cell lung cancer treated with 5-fraction stereotactic body radiation therapy is not associated with treatment schedule Pamela Samson, Sana Rehman, Aditya Juloori, Todd DeWees , Michael Roach, Jeffrey Bradley, … These data confirm that “surgical resection of brain metastases is insufficient to provide durable local control,” the researchers wrote. RSS Feeds . The number of patients presenting with a performance status of 0, 1 or 2 was 15, 7 and 3, respectively. Local control in medically inoperable lung cancer: an analysis of its importance in outcome and factors determining the probability of tumor eradication. It was found that radiotherapy controlled the local disease in 55.4, 50.0, 35.5, and 20.4 percent of the patients initially, but subsequent and further Surgical salvage was successful in 53% of cases with a local recurrence and in 3/8 regional recurrences, resulting in an ultimate locoregional control rate of 83% for N0 patients and 68% for N+ patients. The median follow-up period was 18 (range, 2–90) months. 1992 Dec;25(4):273-9. doi: 10.1016/0167-8140(92)90247-r. Similarly, a signature was found for Local Control (LC) with p = 0.007 and 0.004 and concordance index 0.69 and 0.75. That's why we're explaining what cancer control is, what its goals are, what cancer control programs do, and what the results of successful cancer control look like. Password * The purpose of this study is to investigate the prognostic factors of stereotactic radiotherapy for stage I NSCLC to improve outcomes. The aim of the current two-phase study was to investigate whether hsa-miR-375-signaling through RASD1 could predict local control (LC) in early breast cancer. The 12-month freedom from local recurrence was 43% in the observation group compared with 72% in the SRS group (hazard ratio, 0.46; 95% CI, 0.24–0.88; P = .015). Event Title: Local Control for Pediatric Cancer During the COVID-19 Pandemic Date & Time: Thursday, May 21, 2020 8:00 am Central Daylight Time (Chicago, GMT-05:00) Moderators Karen Marcus, MD, PROS President (Boston Children’s Hospital) Simone Abib, MD, IPSO President, (Federal University of São Paulo) An expert panel of radiation oncologists The primary endpoint was local control rate. For personal accounts OR managers of institutional accounts. The actuarial 3-year local control rate was 53%. Because our local control rate of Stage I primary lung cancer was comparable to those of literatures, we believe that our SBRT technique was not wrong. 58 cases of breast cancer treated primarily by radiotherapy were evaluated to determine the optimum dose for local control. A 53-year-old woman presented with a large left breast tumor and an associated giant ulcer, with massive exudates, bleeding, and an offensive odor. Dr. Overgaard’s work shows that treating the primary In the low risk group, the median OS and LC in the validation group were 14.4 and 28.6 months while in the high-risk group were 9.0 and 17.5 months respectively. Award-winning work by Dr. Marie Overgaard, of the Department of Oncology, Aarhus University Hospital, Denmark, gives new hope of longer survival for women with breast cancer. The fraction of tumor cells S that survive treatment was estimated for each cancer using Equation 4, substituting 0 for t, 0.9 for TCP (which represents the clinically plausible scenario of 90% local tumor control over 5 years for tumors treated without delay), and the cancer-specific P 0 … The results show significant decrease of the LTC (within a constant GTV) by about 10 – 20%, when the TNV increases from 10 cm 3 to 40 cm 3 . Background: Durvalumab after concurrent chemoradiotherapy (CCRT) for locally advanced non-small cell lung cancer (LA-NSCLC) has been found to significantly improve overall survival (OS).However, the effect of durvalumab on local control remains unclear. The comprehensive cancer control approach is used by state, tribes, tribal organizations, territorial and Pacific Island Jurisdiction cancer coalitions to spur local implementation of cancer plans to reduce the burden of cancer in jurisdictions across the country. The possibility of local control of cancer by neoadjuvant chemoradiation therapy with gemcitabine and surgical resection for advanced cholangiocarcinoma Kei Nakagawa , Yu Katayose, Toshiki Rikiyama, Adoru Okaue, Michiaki Unno Results: The patient and treatment characteristics of 81 individuals were similarly distributed between relapse (n = 27) and control groups (n = 54). Home > Learn more about local cancer control. No articles found about local cancer control. This include an improved local tumour control, but there are also data indicating that local treatment might alter the natural course of metastatic disease. Dosoretz DE(1), Galmarini D, Rubenstein JH, Katin MJ, Blitzer PH, Salenius SA, Dosani RA, Rashid M, Mestas G, Hannan SE, et al. But it's sometimes hard to describe what it is. Abstract. The 1-year local control rate was more than 80% even in radioresistant tumors such as renal cell carcinoma, sarcoma or thyroid cancer, but the details of characteristics, including the histology of thyroid cancer, were unknown . A determinate group of 440 patients with this cancer treated from 1945-1959 at one institute were stud- ied.
