We describe the multimodality treatment regimen of a 53-year-old man diagnosed with olfactory neuroblastoma (Kadish stage C) in the right nasal cavity extending into the ethmoid sinus and across the cribriform plate. Endoscopic surgery for tumor resection was followed by a combination of external beam radiotherapy and stereotactic radiosurgery boost with concurrent chemotherapy. The novel combination of dual radiation therapies allowed for the preservation of the nearby optic structures while providing an adequate dosage to a sufficient volume of the afflicted tissue.

Results: To develop a method for reducing the frequency and severity of early radiation reactions in patients with cancer of the uterus or cervix. Material and methods: We analyzed the results of treatment of 60 patients with cancer of the uterus and cervix, patients received a postoperative course of external beam radiotherapy combined with the intramuscular administration of the Derinat® radioprotector (sodium deoxyribonucleate); in the second arm, they received a postoperative course of external beam radiotherapy and standard therapy in case of radiation cystitis. The assessment of radiation reactions severity was performed with the EORTC QLQ-C30 criteria, WBC count, IPSS scale, urine analysis and cystoscopic examination evaluated with the developed by us scale. Results: Evaluation of the quality of life in patients with cervical or uterine cancer at the final stage of treatment using the IPSS scale showed that in the arm of patients with sodium deoxyribonucleate, there was a 30.4 % (p> 0.05) decrease in the symptoms of urinary disorders. The use of the radioprotector sodium deoxyribonucleate also statistically significantly reduced the incidence of radiation cystitis by 73 %. According to cystoscopy, the total bladder injury score at the end of treatment was 147 % lower. The number of leukocytes in the urine analysis at the end of treatment was 116.3 % lower (p≤0.01) in those who received sodium deoxyribonucleate Conclusion: The data obtained indicate the radioprotective efficacy of sodium deoxyribonucleate and make it possible to recommend its intramuscular administration to patients with cancer of the uterus and cervix against the background of external beam radiation therapy to reduce the frequency and severity of acute radiation cystitis in patients with cancer of the uterus or cervical cancer receiving external beam radiation therapy.

Background: Primary spinal tumors are rare and include schwannomas. In the cervical region, these lesions can cause pain, radiculopathy, and/or myelopathy. Case Description: A 53-year-old male presented with 9 months of chronic neck pain and left upper extremity radiculopathy/myelopathy. The MRI revealed an intradural extramedullary C6-C7 mass left-sided mass with foraminal extension. Following a C5-C7 laminectomy with C5-T2 instrumented fusion, the diagnosis of schwannoma with evidence of recent hemorrhage was confirmed by biopsy. Three weeks postoperatively, the patient was pain free, no longer taking opioids, and neurologically intact. Although the MR 6 months later showed no tumor, the MRI 15 months later documented a recurrent enhancing C6-C7 lesion. The patient elected to be treated with external beam radiotherapy and remained asymptomatic. Conclusion: A 53-year-old underwent resection of a cervical C6-C7 schwannoma with intratumoral hemorrhage. Fifteen months following C5-C7 laminectomy with C5-T2 fusion, the tumor recurred and required external beam radiation therapy.

15177 Background: Liver tolerance to reirradiation with multiple doses of 90Y-microspheres is not known. Many patients (pts) have also received external beam radiotherapy to the liver or through the liver and are surviving long enough to be considered for a second and third liver treatments with internal radiation. Methods: The experience of a single center treating liver tumors with resin 90Y-microspheres was used. Pts that received liver radiation prior to or after resin microsphere therapy were studied. Endpoints were toxicity, tumor response, disease type, latency period between radiation treatments, shunting to lung, and effects on liver volume and function. The delivery activity of microspheres selected was not reduced below that which was typically chosen for patients without prior liver radiation which was 25% reduced from the manufacturer’s BSA dose calculation method. All patients received bilobar microsphere delivery during a single session. Results: A total of 40 pts were identified; 14 women, 26 men, treated 6/2003 to 12/2006, with 35 pts receiving 2 courses and 5 pts with 3 courses of liver radiation. Retreatment with resin microspheres 26 pts, prior external beam radiation in 7 pts, prior glass microspheres in 2pts, prior systemic radiotherapy in 2 pts, and prior stereotactic liver radiation in 1 pt. Liver function was stable and adequate in all patients after additional liver radiation, and no pts developed radiation-induced liver dysfunction (RILD) or veno-occlusive disease (VOD). The percentage of shunting to the lung decreased with retreatment. Tumors treated: 14 carcinoid, 11 colorectal, 6 hepatocellular and cholangiocarcinoma, 2 sarcoma, 3 unknown primary, 1 each of breast, esophagus, and head and neck primaries. Conclusions: Repeated radiation to the liver with 90Y-microspheres appears safe in patients that have sufficient normal liver function and reserve based on known laboratory parameters already used for selection of microsphere therapy. No acute life-threatening, fatal, or late liver damage was observed, i.e. RILD or VOD. No specific dose reduction is recommended for retreatment of the liver.

Adenocarcinoma Of The Prostate

201 Background: Traditional wisdom has suggested that under some circumstances radiation therapy may be immunosuppressive, thus obviating effective combination approaches with immunotherapy. Our purpose was to test whether standard radiation therapy for high-risk prostate cancer are immune modulating, thereby prohibiting potential combination with cellular based immunotherapies such as sipuleucel-T. Methods: Retrospective analysis of complete blood count with differential (CBC) data was performed on 26 patients with high-risk adenocarcinoma of the prostate undergoing external beam radiation therapy between January 2008 and November 2010. CBC data were collected prior to radiation therapy and at up to 4 time points thereafter, and compared to normal ranges from an outside reference lab (WBC 3,800-10,700/μL; ALC 910-4,280/μL). Results: The median age was 73 (range 62-86), and 16 patients were on concurrent androgen deprivation therapy. Patients received intensity modulated, dose-escalated external beam radiotherapy. Baseline and subsequent median white blood counts (WBC) and absolute lymphocyte counts (ALC) remained within the normal ranges. In the clinically relevant time frame of <3 months following radiation therapy where sipuleucel-T could be considered, the WBC and ALC were 5,350 and 970, respectively. The median WBC and ALC then gradually increased to 5,800 and 1,250, respectively, at 6-12 months post radiation therapy. Conclusions: These data suggest that in the setting of external beam radiation approaches for high-risk adenocarcinoma of the prostate, no significant changes in either WBC or ALC were observed. The hematologic status in these patients remained stable, suggesting that combination radiation / cellular based immunotherapy approaches are feasible. Further analysis is warranted to test the potential of novel immunotherapeutic agents with radiation therapy. [Table: see text]

For many years the main method of treatment of patients with prostate cancer remains surgical treatment, which consists in performing a difficult and traumatic operations, leading to reduced quality of life. Currently, as an equal alternative to radical prostatectomy is radiotherapy, presented with a standard 3D conformal beam radiation, stereotactic radiotherapy and brachytherapy using sources with a low or high dose. Brachytherapy using sources of high power is a safe and effective treatment for localized prostate cancer, providing a summing fatal dose to the tumor with the short period of hospitalization, minimal complications, which may be used in combination with external beam radiotherapy and standalone version. A brief review of the literature on the use of combined radiation therapy in the treatment of prostate cancer. Describes the comparative characteristics of results of treatment of this pathology, complications, early and late toxic reactions when used brachytherapy isotopes of different dose in combination with external beam radiation therapy. The vector of further research in this direction is justified.

e16147 Background: Prostate cancer is the most common male malignancy, and there is no one standard treatment modality. One treatment option is the combination of external beam radiotherapy and permanent transperineal brachytherapy seed implant Methods: Retrospective review of prostate cancer and side effect outcomes at a single institution in the community setting. All patients were treated with a combination of low dose rate transperineal brachytherapy seed placement and external beam radiation. Results: A total of 897 patients were analyzed, 781 had a minimum follow-up of one year. Median pre-treatment PSA was 8.1 (range 0.3 to 106) and the median Gleason score was 6. With a median follow-up of 3.6 years, 33 (3.4 %) patients had biochemical failure based on the phoenix definition of Nadir + 2. Not including impotence, acute toxicity greater than or equal to Grade 2 was seen in 115 patients (102 GU and 13 GI) and 193 patients had late toxicity greater than or equal to Grade 2 (155 GU and 38 GI). 563 patients received hormone therapy prior to or concurrent with the radiation. Conclusions: This is the largest series reporting on the outcome of combination brachytherpay implant and external beam radiation in the treatment of prostate cancer. Combination treatment using brachytherapy and external beam radiation is well tolerated, with a low rate of biochemical failure and should be considered one of the treatment options for prostate cancer.
