Possible Risk Factors Associated with Radiation Proctitis or Radiation Cystitis in Patients with Cervical Carcinoma after Radiotherapy

Radiation proctitis and radiation cystitis are major complications for patients with cervical carcinomafollowing radiotherapy. In the present study, we aimed to determine the potential risk factors for the developmentof radiation proctitis and radiation cystitis after irradiation. A total of 1,518 patients with cervical carcinomareceived external beam radiotherapy (EBRT) followed by high-dose-rate intracavitary brachytherapy (HDRICB)in our hospital. The incidences of radiation proctitis and radiation cystitis were recorded and associations withdifferent factors (age, time period, tumor stage) were analyzed with c2 (chi-squared) and Fisher exact tests. Wefound that 161 and 94 patients with cervical carcinoma were diagnosed with radiation proctitis and radiationcystitis, respectively, following radiotherapy. The prevalence of Grade I-II radiation proctitis or radiation cystitiswas significantly lower than that of Grade III (radiation proctitis: 3.82% vs. 6.76%, P < 0.05; radiation cystitis:2.31% vs. 3.87%, P < 0.05) and was significantly enhanced in patients with late stage (IIIb) tumor progressioncompared to those in early stage (Ib, IIa) (P < 0.05). Moreover, the incidence of radiation proctitis and cystitiswas not correlated with age or, time period following radiation, for each patient (P > 0.05). These observationsindicate that a late stage of tumor progression is a potential risk factor for the incidence of radiation proctitisand cystitis in cervical carcinoma patients receiving radiotherapy.

Comparing dosimetric and cancer control outcomes after intensity-modulated radiation therapy and tomotherapy for advanced cervical cancer

Concurrent chemoradiation therapy (CCRT) is the standard treatment for locally advanced cervical cancer. The present study aimed to compare the therapeutic responses, toxicities and dosimetric parameters between intensity-modulated radiation therapy (IMRT) and tomotherapy (TOMO) in patients with advanced cervical cancer. This retrospective study included 310 patients with stage IIB-IIIB cervical cancer who underwent CCRT, with 155 patients in each group. Intracavitary brachytherapy was performed after a course of external beam radiation therapy (EBRT), or in the last week of pelvic EBRT. The treatment planning aim at point A (defined as a reference location 2 cm above the vaginal fornix and 2 cm beside the mid axis of the uterus) was >85 Gy in an equivalent dose at 2 Gy. There was no statistical difference with regard to clinicopathological characteristics between the two groups (P>0.05). Improved dose conformity and dose homogeneity (P<0.05) were observed in TOMO planning. TOMO provided more efficacious critical organ sparing than IMRT when assessing the percentage of normal tissue receiving at least 20 Gy (V20) for the bladder, the percentage of normal tissue receiving at least 40 Gy (V40) for the femoral head, and the V40 and V20 for the rectum (P<0.05). TOMO demonstrated a greater ability to protect the ovary (P<0.05). The acute radiation toxicity of proctitis and leukopenia were significantly lower in the TOMO group (P<0.05). The chronic radiation toxicity of radiation enterocolitis and cystitis was lower in the TOMO group (P<0.05). Thus, TOMO provided better critical organ sparing than IMRT. The radiation toxicities were acceptable. Therefore, TOMO appears to be a good option for the treatment of stage IIB-IIIB cervical cancer.

Berberine inhibits acute radiation intestinal syndrome in human with abdomen radiotherapy

Radiation-induced acute intestinal symptoms (RIAISs) are the most relevant complication of abdominal or pelvic radiation. Considering the negative impact of RIAIS on patients’ daily activities, the preventive effects of berberine on RIAIS in patients were investigated. Thirty-six patients with seminoma or lymphomas were randomized to receive berberine oral (n = 18) or not (n = 18). Forty-two patients with cervical cancer were randomized to a trial group (n = 21) and control group (n = 21). Radiotherapy used a parallel opposed anterior and posterior. 300-mg berberine was administered orally three times daily in trial groups. Eight patients with RIAIS were treated with 300-mg berberine three times daily from the third to the fifth week. Toxicities, such as fatigue, anorexia/nausea, etc., were graded weekly according to CTC version 2.0. Patients with abdominal/pelvic radiation in the control group showed grade 1 fatigue, anorexia/nausea, colitis, vomiting, proctitis, weight loss, diarrhea and grade 2 anorexia/nausea, fatigue. Only grade 1 colitis, anorexia/nausea, and fatigue were seen in patients of abdominal radiation treated with berberine. Grade 1 fatigue, colitis, anorexia/nausea, and proctitis occurred in patients of pelvic radiotherapy treated with berberine. Pretreatment with berberine significantly decreased the incidence and severity of RIAIS in patients with abdominal/pelvic radiotherapy when compared with the patients of the control group (P < 0.05). RIAIS were reduced in patients with abdominal radiotherapy/pelvic radiation after receiving berberine treatment. Berberine significantly reduced the incidence and severity of RIAIS and postponed the occurrence of RIAIS in patients with abdominal or whole pelvic radiation.

肺癌患者急性放射性肺损伤发生的相关因素分析

[目的]分析肺癌患者放射治疗后急性放射性肺损伤发生的影响因素。[方法]选取171例肺癌放射治疗的患者,采用Logistic回归分析研究性别、年龄、是否化疗、放疗剂量、V5、V20、平均肺剂量(MLD)等因素与患者3级及以上急性放射性肺损伤发生率的相关性。[结果]171例肺癌放射治疗的患者中,发生3级及以上急性放射性肺损伤50例(29.3%)。单因素分析发现,吸烟、放疗前化疗周期数多、同期放化疗、V5>40%、V20>25%、V20>28%、MLD>10Gy、MLD>13Gy均可导致肺癌患者3级及以上放射性肺损伤发生率的升高。多因素分析显示,吸烟、放疗前化疗周期数多、V20>28%、MLD>13Gy与3级及以上放射性肺损伤发生率有关。[结论]在肺癌放疗计划设计中,应针对中国肺癌患者的特点,设定适合的物理参数;此外,还需考虑患者的吸烟史、化疗史等个体化因素,尽可能降低急性放射性肺损伤的发生率。     

Intensity-modulated Radiotherapy Combined with Endocrine Therapy for Intermediate and Advanced Prostate Cancer: Long-term Outcome of Chinese Patients

Aim: The aim of this study was to evaluate acute adverse events and efficacy of three-dimensional intensitymodulatedradiotherapy (IMRT) combined with endocrine therapy for intermediate and advanced prostatecancer. Methods: Sixty-seven patients were treated with three-dimensional IMRT combined with maximumandrogen blockade. The correlation between radiation-induced rectal injury and clinical factors was furtheranalyzed. Results: After treatment, 21 patients had complete remission (CR), 37 had partial remission (PR), andnine had stable disease (SD), with an overall response rate of 86.5%. The follow-up period ranged from 12.5 to99.6 months. Thirty-nine patients had a follow-up time of ≥ five years. In this group, three-year and five-yearoverall survival rates were 89% and 89.5%, respectively; three-year and five-year progression-free survival rateswere 72% and 63%. In univariate analyses, gross tumor volume was found to be prognostic for survival (χ2 =5.70, P = 0.037). Rates of leucopenia and anemia were 91.1% and 89.5%, respectively. Two patients developedacute liver injury, and a majority of patients developed acute radiation proctitis and cystitis, mainly grade 1/2.Tumor volume before treatment was the only prognostic factor influencing the severity of acute radiation proctitis(P < 0.05). Conclusions: IMRT combined with endocrine therapy demonstrated promising efficacy and was welltolerated in patients with intermediate and advanced prostate cancer.
