The aim of the present study was to determine whether oncologic outcomes and adverse events associated with active on/off intermittent antiandrogen monotherapy (daily bicalutamide, 50 mg per day) are comparable with those of standard external beam radiation therapy (EBRT) or combined androgen blockade (CAB) therapy in prostate cancers with positive surgical margins after radical prostatectomy. Two hundred twenty-three patients with positive surgical margins post-radical prostatectomy who underwent active surveillance (AS, n = 32), EBRT without hormone therapy (n = 55), intermittent antiandrogen monotherapy without EBRT (IAAM, n = 50), or CAB without EBRT (n = 86), between 2007 and 2014, were reviewed retrospectively. Pathologic outcomes, biochemical recurrence rates, radiological disease progression, and adverse events were collected from medical records. Biochemical recurrence rates, biochemical recurrence-free survival rates, and radiological recurrence were not different between the groups (P = 0.225, 0.896, and 0.284, respectively). Adverse event rates and severities were lower for IAAM compared with EBRT or CAB (both P < 0.05), but were comparable to those for AS (P = 0.591 and 0.990, respectively). Grade ≥3 adverse events were not reported in the IAAM or AS groups. Erectile dysfunction and loss of libido rates were lower in the IAAM group compared with the EBRT and CAB groups (P = 0.032). Gastrointestinal complications were more frequently reported in the EBRT group (P = 0.008). Active on/off IAAM treatment might be an appropriate treatment option for patients with positive surgical margins after radical prostatectomy. Furthermore, regarding oncologic outcomes, IAAM was comparable to standard EBRT but had a milder adverse event profile.

OBJECTIVE: To investigate the role of radiotherapy (RT) in patients who underwent hysterectomy for uterine carcinosarcoma (UCS). METHODS: Patients with the International Federation of Gynecology and Obstetrics stage I–IVa UCS who were treated between 1990 and 2012 were identified retrospectively in a multi-institutional database. Of 235 identified patients, 97 (41.3%) received adjuvant RT. Twenty-two patients with a history of previous pelvic RT were analyzed separately. Survival outcomes were assessed using the Kaplan-Meier method and Cox proportional hazards model. RESULTS: Patients with a previous history of pelvic RT had poor survival outcomes, and 72.6% of these patients experienced locoregional recurrence; however, none received RT after a diagnosis of UCS. Univariate analyses revealed that pelvic lymphadenectomy (PLND) and para-aortic lymph node sampling were significant factors for locoregional recurrence-free survival (LRRFS) and disease-free survival (DFS). Among patients without previous pelvic RT, the percentage of locoregional failure was lower for those who received adjuvant RT than for those who did not (28.5% vs. 17.5%, p=0.107). Multivariate analysis revealed significant correlations between PLND and LRRFS, distant metastasis-free survival, and DFS. In subgroup analyses, RT significantly improved the 5-year LRRFS rate of patients who did not undergo PLND (52.7% vs. 18.7% for non-RT, p<0.001). CONCLUSION: Adjuvant RT decreased the risk of locoregional recurrence after hysterectomy for UCS, particularly in patients without surgical nodal staging. Given the poorer locoregional outcomes of patients previously subjected to pelvic RT, meticulous re-administration of RT might improve locoregional control while leading to less toxicity in these patients.

OBJECTIVE: The aim of this analysis was to examine the management of cervix cancer in elderly patients referred for radiotherapy and the results of treatment in terms of overall survival (OS), relapse-free survival (RFS), and treatment-related toxicities. METHODS: Patients were eligible if they were aged ≥75 years, newly diagnosed with cervix cancer and referred for radiotherapy as part of their treatment. Patient details were retrieved from the gynaecology service database where clinical, histopathological treatment and follow-up data were prospectively collected. RESULTS: From 1998 to 2010, 126 patients aged ≥75 years, met selection criteria. Median age was 81.5 years. Eighty-one patients had definitive radiotherapy, 10 received adjuvant radiotherapy and 35 had palliative radiotherapy. Seventy-one percent of patients had the International Federation of Gynecology and Obstetrics stage 1b–2b disease. Median follow-up was 37 months. OS and RFS at 3 years among those treated with curative intent were 66.6% and 75.9% respectively with majority of patients dying without any evidence of cervix cancer. Grade 2 or more late toxicities were: bladder 5%, bowel 11%, and vagina 27%. Eastern Cooperative Oncology Group (ECOG) status was a significant predictor of OS and RFS with each unit increment in ECOG score increased the risk of death by 1.69 times (p<0.001). CONCLUSION: Following appropriate patient selection, elderly patients treated curatively with radiotherapy for cervix cancer have good disease control. Palliative hypofractionated regimens are well tolerated in patients unsuitable for radical treatment.

OBJECTIVE: Lower extremity lymphedema adversely affects quality of life by causing discomfort, impaired mobility and increased risk of infection. The goal of this study is to investigate factors that influence the likelihood of lymphedema in patients with endometrial cancer who undergo adjuvant radiation with or without chemotherapy. METHODS: A retrospective chart review identified all stage I-III endometrial cancer patients who had a hysterectomy with or without complete staging lymphadenectomy and adjuvant radiation therapy between January 2006 and February 2013. Patients with new-onset lymphedema after treatment were identified. Logistic regression was used to find factors that influenced lymphedema risk. RESULTS: Of 212 patients who met inclusion criteria, 15 patients (7.1%) developed new-onset lymphedema. Lymphedema was associated with lymph-node dissection (odds ratio [OR], 5.6; 95% CI, 1.01 to 105.5; p=0.048) and with the presence of pathologically positive lymph nodes (OR, 4.1; 95% CI, 1.4 to 12.3; p=0.01). Multivariate logistic regression confirmed the association with lymph-node positivity (OR, 3.2; 95% CI, 1.0007 to 10.7; p=0.0499) when controlled for lymph-node dissection. Median time to lymphedema onset was 8 months (range, 1 to 58 months) with resolution or improvement in eight patients (53.3%) after a median of 10 months. CONCLUSION: Lymph-node positivity was associated with an increased risk of lymphedema in endometrial cancer patients who received adjuvant radiation. Future studies are needed to explore whether node-positive patients may benefit from early lymphedema-controlling interventions.

PURPOSE: To analyze treatment outcome and side effects of adjuvant radiotherapy using radiotherapy fields and doses which have evolved over the last two decades in a single institution. MATERIALS AND METHODS: Forty-one patients received radiotherapy after orchiectomy from 1996 to 2007. At our institution, the treatment field for stage I seminoma has changed from dog-leg (DL) field prior to 2003 to paraaortic (PA) field after 2003. Fifteen patients were treated with the classic fractionation scheme of 25.5 Gy at 1.5 Gy per fraction. Other patients had been treated with modified schedules of 25.05 Gy at 1.67 Gy per fraction (n=15) and 25.2 Gy at 1.8 Gy per fraction (n=11). RESULTS: With a median follow-up of 112 months, the 5-year and 10-year survival rates were 100% and 96%, respectively, and 5-year and 10-year relapse-free survival rates were both 97.1%. No in-field recurrence occurred. Contralateral seminoma occurred in one patient 5 years after treatment. No grade III-IV acute toxicity occurred. An increased rate of grade 1-2 acute hematologic toxicity was found in patients with longer overall treatment times due to 1.5 Gy per fraction. The rate of grade 2 acute gastrointestinal toxicity was significantly higher with DL field than with PA field and also higher in the 1.8-Gy group than in the 1.5-Gy and 1.67-Gy groups. CONCLUSION: Patients with stage I seminoma were safely treated with PA-only radiotherapy with no pelvic failure. Optimal fractionation schedule needs to be explored further in order to minimize treatment-related toxicity.

OBJECTIVE: The purpose of this study is to investigate the effective of alternating Chemo-radiotherapy for locally Advanced Nasopharyngeal Carcinoma. METHOD: Retrospective analysis 106 cases of patients with locally advanced nasopharyngeal carcinoma between November 2005 and March 2007. All patients received cisplatin-based chemotherapy but 15 patients received radiotherapy(RT) alone. Inducing chemotherapy (IC) + RT + adju-vant chemotherapy (AC) regimen in 36 patients, IC+RT regimen was delivered in 25 patients and AC + RT regimen in 30 patients. 61 patients received 1 to 2 cycles of inducing chemotherapy and 66 patients received 3 to 6 cycles of adjuvant chemotherapy after radiotherapy. Chemotherapy started on the first day after the end of the induction chemotherapy, adjuvant chemotherapy begun after radiotherapy for a week. All patients were treated by radiotherapy using 60 Co r-ray, the nasophyarynx primary site was given a total does of 68 -74 Gy. The lymph nodes of the neck was given 60 to 70 Gy. The prophylactic irradiation does of the neck was 48-50 Gy. RESCULT: The median follow up time was 51 months. A total of 58 patients died, the overall survival rate was 45% in whole groups. The 5-year overall survival rates were 33%, 63%, 60% and 50% in RT, IC + RT + AC, IC + RT and RT+AC group, respectively. The 5-year disease-free survival rates were 13%, 56%, 48% and 40% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year relapse-free survival rates were 13%, 53%, 48% and 50% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year metastasis-free survival rates were 6%, 50%, 44% and 47% in RT, IC + RT + AC, IC+ RT and RT + AC group, respectively. There was significant difference in all groups (P < 0.05). The median time to relapses were 22 months, 29 months, 28 months and 25 months in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The median time to first distant metastasis were 10 months, 19 months, 15 months and 12 months in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. There was no significant difference in all groups (P > 0.05). IC + RT + AC group had heavier acute toxicity effects than other groups, but it did not affect the treatment process, all patients could be tolerated. CONCLUSION This retrospective study has demonstrated that alternating Chemo-radiotherapy and early radiotherapy not only can improve the survival rate for locally Advanced Nasopharyngeal Carcinoma, but also have slight toxicities and side reaction, all patients may tolerated.

PURPOSE: Sorafenib is an effective systemic agent for advanced hepatocellular carcinoma. To increase its efficacy, we evaluated the feasibility and benefit of sorafenib combined with radiotherapy. MATERIALS AND METHODS: From July 2007 to July 2011, 31 patients were treated with a daily dose of 800 mg of sorafenib and radiotherapy. Among them, 13 patients who received radiotherapy on the bone metastasis were excluded. Thirteen patients received 30-54 Gy of radiotherapy on the primary tumor (primary group) and 5 patients received 30-58.4 Gy on the measurable metastatic lesions (measurable metastasis group). Tumor responses at 1 month after the completion of radiotherapy and overall survival were evaluated. RESULTS: The in-field response rate was 100% in the primary group and 60% in the measurable metastasis group. A decrease of more than 80% in the tumor marker alpha-fetoprotein was observed in 7 patients in the primary group (54%). Toxicities of grades 3-4 were hand-foot syndrome in 3 (17%) patients, duodenal bleeding in 1 (6%) patient, thrombocytopenia in 3 (17%) patients and elevation of aspartate transaminase in 1 (6%) patient. The median overall survival was 7.8 months (95% confidence interval, 3.0-12.6). CONCLUSION: The combined treatment of sorafenib and radiotherapy was feasible and induced substantial tumor responses in the target lesions. The results of this study emphasize the importance of individualized approach in the management of advanced hepatocellular carcinoma and encourage the initiation of a controlled clinical trial.

OBJECTIVETo summarize the experiences in gallbladder cancer treatment, evaluate the efficacy of postoperative radiotherapy, and investigate the method of improving the survival of gallbladder cancer patients.

METHODSOne hundred and twenty-seven gallbladder cancer patients, treated in our center by radical resection (84 cases) and combined with postoperative radiotherapy (43 cases), between June 2003 to December 2009 were included in this study. Their clinical data and follow-up results were retrospectively analyzed. According to AJCC staging criteria, the survival time and 1-, 3- and 5-year survival rates of the surgery group and the postoperative radiotherapy group at the different pathological stages and resection margin status were compared.

RESULTSThe median survival time of postoperative radiotherapy patients in stage III was 16.9 months, and the 1-year, 3-year, and 5-year survival rates were 55.7%, 23.5% and 18.2%, respectively, significantly higher than that of the simple operation group ( median survival time 14.3 months, and 1-year, 3-year, 5-year survival rates 42.7%, 22.6% and 16.7%, respectively) (P<0.05). The median survival time of postoperative radiotherapy patients in stage IV, the median survival time was 9.7 months in the postoperative radiotherapy group and 6.3 months in the simple surgery group, and the 1-year survival rates were 14.2% and 9.8%, the 3-year survival rates were 7.2% and 3.9%, the 5-year survival rates were 7.2% and 1.9%, respectively, all showing a statistically significant difference (P<0.05). Among the stage III and IVpatients, all the 1-, 3- and 5-year survival rates of the postoperative radiotherapy group were higher than that of the simple R0 and R1 surgical resection group (all P<0.05), but with a non-significant difference between the stageIandIIpatients (P>0.05). The main side effects in postoperative radiotherapy patients including nausea, vomiting and abdominal pain, all were successfully alleviated by symptomatic and supportive therapy, and the radiotherapy was successfully completed.

CONCLUSIONSWith regard to the gallbladder cancer patients in stage III and IV, the survival rate can be obviously increased by postoperative radiotherapy. However, for patients in stageIand II, whether postoperative radiotherapy significantly improves the survival or not, needs to be further validated in larger scale studies.

OBJECTIVETo analyze the complications and short-term outcomes of patients receiving intraoperative electron radiotherapy (IOERT) for locally advanced and recurrent periarticular soft tissue sarcomas of the extremities.

METHODSTwenty-one adult patients with locally advanced and/or recurrent periarticular soft tissue sarcomas of the extremities treated with IOERT were included in this study. Among them 14 patients had recurrent diseases after prior operation and 7 patients with locally advanced disease with primary treatment. The total dose of radiation ranged from 11 Gy to 21 Gy of 6 - 12 MeV beta ray given by intraoperative radiotherapy after complete tumor resection with negative margins. Five patients were given external beam radiotherapy (EBRT) with a total dose of 40 - 50 Gy, and 10 patients received chemotherapy.

RESULTSThe median follow-up time was 15 months. Five patients (23.8%) had tumor relapse, including one patients with local recurrence, one patient with regional recurrence, two patients with distant metastasis and one patient with local recurrence and distant metastasis. The actuarial local control rate at 1 year was 95.2% (20/21), and at 2 years was 90.5% (19/21). Acute skin toxicity (RTOG) within 3 months after surgery included grade I in 6 patients and grade II in 3 patients. Two year late skin toxicity (RTOG/EORTC) included grade I in 4 patients and grade II in 2 patients. Fibrosis included grade I in 3 patients and grade II in 3 patients. Six patients had joint dysfunction (3 patients with grade I and 3 with grade II) and 6 patients had healing problems. One patient got ipsilateral schiatic neuritis 9 months after IOERT. No adverse events occurred during surgery.

CONCLUSIONSIOERT brings tolerable complications of acute and late toxicities and favorable local control rate. IOERT should be followed by postoperative radiotherapy or increase the intraoperative radiation dose for locally advanced and recurrent sarcomas to get a better local control. Otherwise, distant metastasis is one of the main reasons of treatment failure, so chemotherapy should be added to the treatment regimen.
