Abstract
Introduction Despite modern radiotherapy (RT) techniques, radiation-induced proctitis (RIP) remains a significant complication of RT for pelvic organ malignancies. Over the last decades, an enormous therapeutic armamentarium has been considered in RIP, including hyperbaric oxygen therapy (HBOT). However, the evidence regarding the impact of HBOT on RIP is conflicting. This study aims to evaluate the effectiveness and safety of HBOT in the treatment of RIP. Methods Ten-year (2013-2023) retrospective analysis of all consecutive patients with RIP treated with HBOT at Centro de Medicina Subaquática e Hiperbárica (CMSH) (Armed Forces Hospital - Lisbon, Portugal). Patients were exposed to 100% oxygen at 2.5 ATA, in a multiplace first-class hyperbaric chamber, for 70-min periods, once daily, five times per week. Fisher's exact test was performed using SPSS (version 23.0); p<0.05 was accepted as statistically significant. Results Of a total of 151 patients with RIP, 88 were included in the final analysis, of whom 38.6% evidenced other concurrent radiation-induced soft tissue lesions. The most reported primary pelvic tumor treated with RT was prostate cancer (77.3%), followed by cervical cancer (10.2%). Hematochezia was the most observed clinical manifestation (86.4%). After a median of 60 HBOT sessions (interquartile range [IQR]: 40-87.5), 62.5% and 31.8% of patients achieved a clinical complete and partial response, respectively, with a hematochezia resolution rate of 93.7% (complete or partial). While partial and complete responses require fewer than 70 sessions of HBOT in terms of overall RIP symptoms (p=0.069), isolated hematochezia tends to require at least 70 sessions (p=0.075). Individuals with at least two concurrent late radiation tissue injuries were associated with a complete response to HBOT (p=0.029). Only about 5.7% of patients did not respond to the treatment. Eighteen patients (20.5%) developed reversible ear barotrauma. The number of HBOT sessions was a predictor of HBOT side effects (odds ratio: 1.010; 95% confidence interval, 1.000-1.020; p=0.047). Conclusion The HBOT proved to be an effective and safe treatment for RIP refractory to medical and/or endoscopic treatments. This real-world evidence study adds value to published data on the management of RIP with HBOT.

Abstract
Radiotherapy (RT) is the backbone of multimodality treatment of more than half of cancer cases. Despite new modern RT techniques, late complications may occur such as radiation proctitis (RP). The natural history of RP is unpredictable. Minor symptoms may resolve spontaneously or require conservative treatment. On the other hand, for similar and uncomplicated clinical contexts, symptoms may persist and can even be refractory to the progressive increase in treatment measures. Over the last decades, an enormous therapeutic armamentarium has been considered in RP, including hyperbaric oxygen therapy (HBOT). Currently, the evidence regarding the impact of HBOT on RP and its benefits is conflicting. Additional prospective and randomised studies are necessary to validate HBOT’s effectiveness in the ‘real world’ clinical practice. This article reviewed the relevant literature on pathophysiology, clinical presentation, different classifications and discuss RP management including a proposal for a therapeutic algorithm with a focus on HBOT.

Abstract
Radiation proctitis is a common complication after radiotherapy for pelvic malignant tumors. This study was conducted to assess the efficacy of novel almagate enemas in hemorrhagic chronic radiation proctitis (CRP) and evaluate risk factors related to rectal deep ulcer or fistula secondary to CRP. All patients underwent a colonoscopy to confirm the diagnosis of CRP and symptoms were graded. Typical endoscopic and pathological images, risk factors, and quality of life were also recorded. A total of 59 patients were enrolled. Gynecological cancers composed 93.1% of the primary malignancies. Complete or obvious reduction of bleeding was observed in 90% (53/59) patients after almagate enema. The mean score of bleeding improved from 2.17 to 0.83 (P<0.001) after the enemas. The mean response time was 12 days. No adverse effects were found. Moreover, long-term successful rate in controlling bleeding was 69% and the quality of life was dramatically improved (P=0.001). The efficacy was equivalent to rectal sucralfate, but the almagate with its antacid properties acted more rapidly than sucralfate. Furthermore, we firstly found that moderate to severe anemia was the risk factor of CRP patients who developed rectal deep ulcer or fistulas (P= 0.015). We also found abnormal hyaline-like thick wall vessels, which revealed endarteritis obliterans and the fibrosis underlying this disease. These findings indicate that almagate enema is a novel effective, rapid and well-tolerated method for hemorrhagic CRP. Moderate to severe anemia is a risk factor for deep ulceration or fistula.

[PMID: 27350738 PMCID: PMC4917620 DOI: 10.3748/wjg.v22.i24.5598] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2016] [Revised: 04/05/2016] [Accepted: 05/04/2016] [Indexed: 02/06/2023] Open
Abstract
AIM: To assess the efficacy and safety of diverting colostomy in treating severe hemorrhagic chronic radiation proctitis (CRP).
METHODS: Patients with severe hemorrhagic CRP who were admitted from 2008 to 2014 were enrolled into this study. All CRP patients were diagnosed by a combination of pelvic radiation history, clinical rectal bleeding, and endoscopic findings. Inclusion criteria were CRP patients with refractory bleeding with moderate to severe anemia with a hemoglobin level < 90 g/L. The study group included patients who were treated by diverting colostomy, while the control group included patients who received conservative treatment. The remission of bleeding was defined as complete cessation or only occasional bleeding that needed no further treatment. The primary outcome was bleeding remission at 6 mo after treatment. Quality of life before treatment and at follow-up was evaluated according to EORTC QLQ C30. Severe CRP complications were recorded during follow-up.
RESULTS: Forty-seven consecutive patients were enrolled, including 22 in the colostomy group and 27 in the conservative treatment group. When compared to conservative treatment, colostomy obtained a higher rate of bleeding remission (94% vs 12%), especially in control of transfusion-dependent bleeding (100% vs 0%), and offered a better control of refractory perianal pain (100% vs 0%), and a lower score of bleeding (P < 0.001) at 6 mo after treatment. At 1 year after treatment, colostomy achieved better remission of both moderate bleeding (100% vs 21.5%, P = 0.002) and severe bleeding (100% vs 0%, P < 0.001), obtained a lower score of bleeding (0.8 vs 2.0, P < 0.001), and achieved obvious elevated hemoglobin levels (P = 0.003), when compared to the conservative treatment group. The quality of life dramatically improved after colostomy, which included global health, function, and symptoms, but it was not improved in the control group. Pathological evaluation after colostomy found diffused chronic inflammation cells, and massive fibrosis collagen depositions under the rectal wall, which revealed potential fibrosis formation.
CONCLUSION: Diverting colostomy is a simple, effective and safe procedure for severe hemorrhagic CRP. Colostomy can improve quality of life and reduce serious complications secondary to radiotherapy.

Abstract
As clinical outcomes for patients with clinically localized prostate cancer continue to improve, patients and physicians are increasing making treatment decisions based on concerns regarding long-term morbidity. A primary concern is late radiation proctitis, a clinical entity embodied by various signs and symptoms, ranging from diarrhea to rectal fistulas. Here, we present a comprehensive literature review examining the clinical manifestations and pathophysiology of late radiation proctitis after low-dose-rate brachytherapy (BT), as well as its incidence and predictors. The long-term risks of rectal bleeding after BT are on the order of 5-7%, whereas the risks of severe ulceration or fistula are on the order of 0.6%. The most robust predictor appears to be the volume of rectum receiving the prescription dose. In certain situations (e.g., salvage setting, for patients with increased radiosensitivity, and following aggressive biopsy after BT), the risk of these severe toxicities may be increased by up to 10-fold. A variety of excellent management options exist for rectal bleeding, with endoscopic methods being the most commonly used.

Abstract
Pelvic radiation disease (PRD) occurs in 2-11% of patients undergoing pelvic radiation for urologic and gynecologic malignancies. Hyperbaric oxygen therapy (HBOT) has previously been described as a noninvasive therapeutic option for the treatment of PRD. the purpose of study was to analyze prospectively the results of HBOT in 44 consecutive patients with PRD who were resistant to conventional oral or topical treatments. Material and Methods. The median age of the cohort was 65.7 years (39-85). Twenty-seven percent of patients required blood transfusion (n = 12). The median of delay between radiotherapy and HBOT was 26 months (3-175). We evaluated the results of HBOT, using SOMA-LENT Scale. Results. SOMA-LENT score was decreased in 59% of patient. The median of SOMA-LENT score before HBOT was significantly higher, being equal to 14 (0-36), than after HBOT with the SOMA-LENT score of 12 (0-38) (P = 0.003). Tenesmus (P = 0.02), bleeding (P = 0.0001), and ulceration (P = 0.001) significantly decreased after HBOT. Regarding patients with colostomy, 33% (n = 4) benefited from colostomies closure. HBOT was generally well tolerated. Only one patient stopped precociously due to transient myopia. Conclusion. This study is in favor of the interest of HBOT in pelvic radiation disease treatment (PRD).

Abstract
AIM This study aimed at investigating factors associated to late rectal and bladder toxicity following radiation therapy and the effectiveness of Hyperbaric Oxygen Therapy (HBOT) when toxicity is grade ≥2. BACKGROUND Radiation is frequently used for prostate cancer, but a 5-20% incidence of late radiation proctitis and cystitis exists. Some clinical and dosimetric factors have been defined without a full agreement. For patients diagnosed of late chronic proctitis and/or cystitis grade ≥2 treatment is not well defined. Hyperbaric Oxygen Therapy (HBOT) has been used, but its effectiveness is not well known. MATERIALS AND METHODS 257 patients were treated with radiation therapy for prostate cancer. Clinical, pharmacological and dosimetric parameters were collected. Patients having a grade ≥2 toxicity were treated with HBOT. Results of the intervention were measured by monitoring toxicity by Common Toxicity Criteria v3 (CTCv3). RESULTS Late rectal toxicity was related to the volume irradiated, i.e. V50 > 53.64 (p = 0.013); V60 > 38.59% (p = 0.005); V65 > 31.09% (p = 0.002) and V70 > 22.81% (p = 0.012). We could not correlate the volume for bladder. A total of 24 (9.3%) patients experienced a grade ≥2. Only the use of dicumarinic treatment was significant for late rectal toxicity (p = 0.014). A total of 14 patients needed HBOT. Final percentage of patients with a persistent toxicity grade ≥2 was 4.5%. CONCLUSION Rectal volume irradiated and dicumarinic treatment were associated to late rectal/bladder toxicity. When toxicity grade ≥2 is diagnosed, HBOT significantly ameliorate symptoms.

Abstract
PURPOSE The aim of this study was to review the available literature and define clinical practice guidelines for the use of agents for the prevention and treatment of gastrointestinal mucositis. METHODS A systematic review was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO). The body of evidence for each intervention, in each cancer treatment setting, was assigned an evidence level. Based on the evidence level, one of the following three guideline determinations was possible: recommendation, suggestion, and no guideline possible. RESULTS A total of 251 clinical studies across 29 interventions were examined. Panel members were able to make one new evidence-based negative recommendation; two new evidence-based suggestions, and one evidence-based change from previous guidelines. Firstly, the panel recommends against the use of misoprostol suppositories for the prevention of acute radiation-induced proctitis. Secondly, the panel suggests probiotic treatment containing Lactobacillus spp., may be beneficial for prevention of chemotherapy and radiotherapy-induced diarrhea in patients with malignancies of the pelvic region. Thirdly, the panel suggests the use of hyperbaric oxygen as an effective means in treating radiation-induced proctitis. Finally, new evidence has emerged which is in conflict with our previous guideline surrounding the use of systemic glutamine, meaning that the panel is unable to form a guideline. No guideline was possible for any other agent, due to inadequate and/or conflicting evidence. CONCLUSIONS This updated review of the literature has allowed new recommendations and suggestions for clinical practice to be reached. This highlights the importance of regular updates.

Abstract
Background Radiation proctitis after intensity-modulated radiation therapy (IMRT) differs from that seen after pelvic irradiation in that this adverse event is a result of high-dose radiation to a very small area in the rectum. We evaluated the results of treatment for hemorrhagic proctitis after IMRT for prostate cancer. Methods Between November 2004 and February 2010, 403 patients with prostate cancer were treated with IMRT at 2 institutions. Among these patients, 64 patients who developed late rectal bleeding were evaluated. Forty patients had received IMRT using a linear accelerator and 24 by tomotherapy. Their median age was 72 years. Each patient was assessed clinically and/or endoscopically. Depending on the severity, steroid suppositories or enemas were administered up to twice daily and Argon plasma coagulation (APC) was performed up to 3 times. Response to treatment was evaluated using the Rectal Bleeding Score (RBS), which is the sum of Frequency Score (graded from 1 to 3 by frequency of bleeding) and Amount Score (graded from 1 to 3 by amount of bleeding). Stoppage of bleeding over 3 months was scored as RBS 1. Results The median follow-up period for treatment of rectal bleeding was 35 months (range, 12–69 months). Grade of bleeding was 1 in 31 patients, 2 in 26, and 3 in 7. Nineteen of 45 patients (42%) observed without treatment showed improvement and bleeding stopped in 17 (38%), although mean RBS did not change significantly. Eighteen of 29 patients (62%) treated with steroid suppositories or enemas showed improvement (mean RBS, from 4.1 ± 1.0 to 3.0 ± 1.8, p = 0.003) and bleeding stopped in 9 (31%). One patient treated with steroid enema 0.5-2 times a day for 12 months developed septic shock and died of multiple organ failure. All 12 patients treated with APC showed improvement (mean RBS, 4.7 ± 1.2 to 2.3 ± 1.4, p < 0.001) and bleeding stopped in 5 (42%). Conclusions After adequate periods of observation, steroid suppositories/enemas are expected to be effective. However, short duration of administration with appropriate dosage should be appropriate. Even when patients have no response to pharmacotherapy, APC is effective.

Abstract
INTRODUCTION Radiation proctitis is a common complication following radiation therapy for pelvic malignancies. There have been no formal trials of treatment for radiation proctitis and a variety of methods are currently used. We assessed the efficacy of rebamipide enema to control symptoms and proctoscopic findings from radiation proctitis. MATERIALS AND METHODS Fifteen patients with radiation proctitis were enrolled. Enemas containing 150 mg rebamipide per dosing were administered after morning bowel movement, and always prior to bedtime, twice daily for 4 weeks. The efficacy of treatment was assessed from clinical symptoms (Subjective Objective Management Analysis Scale for Rectal Toxicity) and endoscopic findings. RESULTS The mean bleeding score improved from 2.67 to 0.53 (P < 0.01). The mean symptom scores improved in those patients who had pain (0.40 to 0.13), tenesmus (0.40 to 0.20), and stool frequency (0.27 to 0.13). The mean improvement in telangiectasia scores (2.13 to 0.80, P < 0.01), bleeding point scores (1.80 to 0.27, P < 0.01), and friable mucosa scores (1.33 to 0.20, P < 0.01) were all statistically significant. No side effects were noted in any patients. CONCLUSION Rebamipide enema therapy for radiation proctitis is a safe and effective treatment of radiation proctitis. We suggest the value of rebamipide enema in the treatment of radiation proctitis when other conservative management or first treatment has failed.

Abstract
This prospective randomised controlled study of 40 patients could not show a statistically significant advantage with 6 months of pentoxifylline compared with standard measures for late radiation-induced rectal bleeding. However, a modest benefit cannot be excluded and larger randomised placebo-controlled trials with longer durations of pentoxifylline treatment may be justified.

Abstract
PURPOSE The short-term safety and efficacy of 2 percent formalin administered as a retention enema for hemorrhagic radiation proctitis was studied. METHODS A group of 24 patients with hemorrhagic radiation proctitis who received radical radiotherapy were administered 2 percent formalin as a retention enema and the treatment was followed up from 1 to 29 (mean, 15.34) weeks. The enema was performed on an outpatient basis under sedation with pentazocine and promethazine with a retention time of two minutes. The symptoms and proctoscope findings were graded and converted into a numeric score, ranging from 1 to 4. The mean improvements in scores before treatment and after the last follow-up were analyzed for statistical significance by using the paired t-test. RESULTS There was complete cessation of bleeding in 47.8 percent of patients and very negligible bleeding in 30.4 percent. A total of 78.2 percent responded positively to treatment with 2 percent formalin retention enema. More than one application was required in 34.7 percent of the patients. The procedure was well tolerated and most of the side effects were mild. Side effects were diarrhea in 23.5 percent, abdominal pain and tenesmus in 8.8 percent, and fever with vomiting in 2.9 percent of patients. There was a statistically significant reduction in bleeding and proctoscopy scores (P<0.01). None of the patients in this study required surgery to palliate their symptoms. CONCLUSIONS Two percent formalin when given as a retention enema is a safe, inexpensive, and effective intervention for hemorrhagic radiation proctitis. Any trained health worker using simple precautions can perform this procedure. The long-term efficacy and safety of 2 percent formalin retention enemas need further assessment with randomized, controlled trials.

Abstract
Late complications are one of the major factors limiting radiotherapy treatment, and their treatment is not codified. Hyperbaric oxygen (HBO) has been used in combination with radiotherapy for over half a century, either to maximise its effectiveness or in an attempt to treat late complications. In this latter case, retrospective trials and case reports are prevailing in literature. This prompted European Society for Therapeutic Radiotherapy and Oncology and European Committee for Hyperbaric Medicine to organise a consensus conference in October 2001, dealing with the HBO indications on radiotherapy for the treatment and prevention of late complications. This updated literature review is part of the documents the jury based its opinion on. A systematic search was done on literature from 1960 to 2004, by only taking into account the articles that appeared in peer review journals. Hyperbaric oxygen treatment involving complications to the head and neck, pelvis and nervous system, and the prevention of complications after surgery in irradiated tissues have been studied. Despite the small number of controlled trials, it may be indicated for the treatment of mandibular osteoradionecrosis in combination with surgery, haemorrhagic cystitis resistant to conventional treatments and the prevention of osteoradionecrosis after dental extraction, whose level of evidence seems to be the most significant though randomised trials are still necessary. The other treatment methods are also outlined for each location.

Abstract
BACKGROUND Oral and gastrointestinal (GI) mucositis can affect up to 100% of patients undergoing high-dose chemotherapy and hematopoietic stem cell transplantation, 80% of patients with malignancies of the head and neck receiving radiotherapy, and a wide range of patients receiving chemotherapy. Alimentary track mucositis increases mortality and morbidity and contributes to rising health care costs. Consequently, the Multinational Association of Supportive Care in Cancer and the International Society for Oral Oncology assembled an expert panel to evaluate the literature and to create evidence-based guidelines for preventing, evaluating, and treating mucositis. METHODS Thirty-six panelists reviewed literature published between January 1966 and May 2002. An initial meeting in January 2002 produced a preliminary draft of guidelines that was reviewed at a second meeting the same year. Thereafter, a writing committee produced a report on mucositis pathogenesis, epidemiology, and scoring (also included in this issue), as well as clinical practice guidelines. RESULTS Panelists created recommendations from higher levels of evidence and suggestions when evidence was of a lower level and there was a consensus regarding the interpretation of the evidence by the panel. Panelists identified gaps in evidence that made it impossible to recommend or not recommend use of specific agents. CONCLUSIONS Oral/GI mucositis is a common side effect of many anticancer therapies. Evidence-based clinical practice guidelines are presented as a benchmark for clinicians to use for routine care of appropriate patients and as a springboard to challenge clinical investigators to conduct high-quality trials geared toward areas in which data are either lacking or conflicting.

Abstract
Chronic radiation proctitis represents a challenging condition seen with increased frequency due to the common use of radiation for treatment of pelvic cancer. Hemorrhagic radiation proctitis represents the most feared complication of chronic radiation proctitis. There is no consensus for the management of this condition despite the great number of clinical approaches and techniques that have been employed. Rectal resection represents an available option although associated with high morbidity and risk of permanent colostomy. The effectiveness of nonoperative approaches remains far from desirable, and hemorrhagic recurrence represents a major drawback that leads to a need for consecutive therapeutic sessions and combination of techniques. We conducted a critical review of published reports regarding conservative management of hemorrhagic chronic radiation proctitis. Although prospective randomized trials about hemorrhagic radiation proctitis are still lacking, there is enough evidence to conclude that topical formalin therapy and an endoscopic approach delivering an argon plasma coagulation represent available options associated with elevated effectiveness for interruption of rectal bleeding in patients with chronic radiation proctitis.

Abstract
Endoscopic thermal therapy and formalin are being increasingly recommended for the treatment of chronic hemorrhagic radiation proctitis. It may be too early, however, to discard pharmacologic agents from the management process, especially in medical institutions where specialized equipment is unavailable. We prospectively assessed the effectiveness of medical therapy in 14 consecutive patients with chronic hemorrhagic radiation proctitis from July 1999 to June 2001. All 14 subjects were women (mean age 56 years), 13 of whom had had radiotherapy for cancer of the cervix. The median time to onset of symptoms following irradiation was 16 months. Six patients had a hemoglobin level of < 8 g/dl, and blood transfusion was required in 11 patients. In five patients (36%) initially treated with hydrocortisone enemas prior to referral, this treatment continued; and the remaining nine patients were commenced on sucralfate enemas. Two patients given rectal hydrocortisone continued to bleed and were treated with sucralfate enemas and topical formalin, respectively. Rectal sucralfate suspension effectively procured symptomatic alleviation in all 11 patients. Rectal bleeding recurred in two patients who had been managed exclusively with hydrocortisone and sucralfate enemas, respectively, over a mean follow-up of 6 months. Both patients were managed with topical formalin, which controlled their symptoms. Even though the number of subjects in this study is small, sucralfate enema can be recommended as an effective first-line agent for managing patients with chronic hemorrhagic radiation proctitis. The use of more specialized therapy can therefore be reserved for cases where primary treatment failure occurs with sucralfate therapy.

Abstract
Chronic radiation proctitis produces a range of clinical symptoms for which there is currently no recommended standard management. The aim of this review was to identify the various non-surgical treatment options for the management of late chronic radiation proctitis and evaluate the evidence for their efficacy. Synonyms for radiation therapy and for the spectrum of lower gastrointestinal radiation toxicity were combined in an extensive search strategy and applied to a range of databases. The included studies were those that involved interventions for the non-surgical management of late radiation proctitis. Sixty-three studies were identified that met the inclusion criteria, including six randomised controlled trials that described the effects of anti-inflammatory agents in combination, rectal steroids alone, rectal sucralfate, short chain fatty acid enemas and different types of thermal therapy. However, these studies could not be compared. If the management of late radiation proctitis is to become evidence based, then, in view of its episodic and variable nature, placebo controlled studies need to be conducted to clarify which therapeutic options should be recommended. From the current data, although certain interventions look promising and may be effective, one small or modest sized study, even if well-conducted, is insufficient to implement changes in practice. In order to increase recruitment to trials, a national register of cases with established late radiation toxicity would facilitate multi-centre trials with specific entry criteria, formal baseline and therapeutic assessments providing standardised outcome data.

Abstract
BACKGROUND Chronic radiation proctitis (inflammation of the rectum) may develop after the completion of pelvic radiotherapy. Presently there is no recommended standard management. OBJECTIVES To assess the effects of various non-surgical treatment options for the management of late chronic radiation proctitis. SEARCH STRATEGY We searched the Cochrane Controlled Trials Register, issue 1, 2001, MEDLINE 1966 to 2001, EMBASE 1980 to 2001, CANCERCD 1980 to 2001, Science Citation Index 1991 to 2001, CINAHL 1982 to 2001, as well as sources of grey literature. We also hand searched relevant textbooks and contacted experts in the field. SELECTION CRITERIA Studies (preferentially randomised controlled trials) of interventions for the non-surgical management of late radiation proctitis in patients who have undergone pelvic radiotherapy as part of their cancer treatment. DATA COLLECTION AND ANALYSIS The inclusion criteria were independently applied by two of the reviewers (AD and EJM) and where there was disagreement this was resolved by involving a third reviewer to form a consensus. MAIN RESULTS Six randomised controlled trials were included. None of the trials compared anti-inflammatories with placebo. However rectal sucralfate showed greater clinical improvement for proctitis than anti-inflammatories (odds ratio 14.00, 95% confidence interval 1.46 to 134.26; n=1 study), though no difference was seen for endoscopic improvement (odds ratio 2.74, 95% confidence interval 0.64 to 11.76, n=1 study). The addition of metronidazole to the anti-inflammatory regime also appeared to improve the response rate, as measured by the reduction in rectal bleeding, diarrhoea, erythema and ulceration (n=1 study). Similarly rectal hydrocortisone appeared to be more effective than rectal betamethasone for clinical improvement although no difference was seen in endoscopic improvement (n=1 study). Short chain fatty acid enemas did not appear to be effective compared to placebo (n=2 studies). In the comparison of the heater probe and bipolar electrocautery (n=1 study), there was no discernible difference for severe bleeding after one year, but the heater probe demonstrated a greater increase in the haematocrit and reduced transfusion requirements. REVIEWER'S CONCLUSIONS Late radiation complications are a relatively rare manifestation, with many potential carers and poor diagnostic criteria. Although certain interventions look promising and may be effective (such as rectal sucralfate, adding metronidazole to the anti-inflammatory regime and heater probes), single small studies (even if well conducted) provide insufficient evidence. The episodic and variable nature of late radiation proctitis also requires placebo controlled studies to establish whether particular treatments are effective. Regional or centralised registers of radiation toxicity should be established so that interventions can be administered in the setting of multi-centre trials with specific entry criteria, formal baseline and therapeutic assessments providing standardised outcome data including quality of life evaluations.

Abstract
PURPOSE We report the results of hyperbaric oxygen therapy (HBO) used in the treatment of radiation cystitis and proctitis following irradiation of prostate cancer. MATERIALS AND METHODS Between June 1995 and March 2000, 18 men (median age 71 years) with radiation proctitis (n=7), cystitis (n=8), and combined proctitis/cystitis (n=3) underwent HBO therapy in a multiplace chamber for a median of 26 sessions (range 2-60). The treatment schedule (2.2-2.4 atmospheres absolute, 60 min bottom time, once-a-day, 7 days a week) was set at a lower limit of 20 sessions; the upper limit was left open to symptom-related adjustment. Prior to HBO treatment, RTOG/EORTC late genitourinal (GU) morbidity was Grade 2 (n=3), Grade 3 (n=6) or Grade 4 (n=2); modified RTOG/EORTC late gastrointestinal (GI) morbidity was either Grade 2 (n=4) or Grade 3 (n=6). RESULTS Sixteen patients underwent an adequate number of sessions. RTOG/EORTC late GU as well as modified GI morbidity scores showed a significant improvement after HBO (GI, P=0.004; GU, P=0.004; exact Wilcoxon signed rank test); bleeding ceased in five out of five patients with proctitis and in six out of eight patients with cystitis; one of those two patients, in whom an ineffective treatment outcome was obtained, went on to have a cystectomy. CONCLUSIONS HBO treatment seems to be an effective tool to treat those patients with late GI and GU morbidity when conventional treatment has led to unsatisfactory results. Particularly in patients with radiation cystitis, HBO should not be delayed too long, as in the case of extensive bladder shrinkage improvement is hard to achieve.

Abstract
PURPOSE As transperineal interstitial permanent prostate brachytherapy (TIPPB) grows in acceptance as an option in the treatment of organ-confined prostate cancer, its associated toxicities are being defined. This clinical report documents rectal toxicity from a large cohort of men treated by a single practitioner for adenocarcinoma of the prostate. METHODS AND MATERIALS Eight hundred twenty-five men were treated from September 1992 to September 1998 with TIPPB. One hundred-forty were treated in conjunction with external beam irradiation (EBRT) and 685 with TIPPB alone. All patients were implanted under real-time ultrasound guidance. No dose-volume histogram analysis was performed for this study. All patients were followed at 5 weeks after the procedure, then every 3-6 months thereafter. Rectal morbidity was graded by a modified RTOG toxicity scale. Therapy to control symptoms was recommended on an individual basis. RESULTS The median follow-up for the cohort is 48 months. A total of 77 patients (9.4%) reported Grade 1 toxicity at some time following an implant whereas 54 patients (6.6%) reported Grade 2 toxicity. The peak post-TIPPB time for experiencing rectal toxicity was 8 months at which time Grade 1 and 2 rectal toxicity was reported in 9.5% of the patients. This improved over the subsequent months and resolved in all patients by 312 years. Four patients (0.5%) reported Grade 3 rectal toxicity with rectal ulceration identified on colonoscopy at 1 year from implant. Two of the four patients had colonic manipulation in the radiated portion of the colon which subsequently caused it to bleed. None of the patients required blood product transfusion. In 3 of the 4 patients the Grade 3 rectal toxicity has resolved spontaneously and 1 patient continues to heal at the time of this report. No patient required hospitalization or surgical intervention. CONCLUSION TIPPB is a tolerable and acceptable treatment option when used alone in early-stage, organ-confined adenocarcinoma of the prostate and in conjunction with EBRT in more advanced disease. This clinical report adds to the growing literature regarding the potential morbidity associated with this procedure and indicates that serious rectal injury is rare.

Abstract
BACKGROUND Radiation-induced proctosigmoiditis is a serious complication of pelvic radiation therapy. Rectal bleeding occurs among 6% to 8% of these patients and is extremely difficult to manage. Pharmacotherapy is generally ineffective, whereas surgical treatment is associated with high morbidity and mortality. Argon plasma coagulation is a new method of noncontact electrocoagulation well suited for hemostasis of large bleeding areas. METHODS From December 1996 through March 1998, we used argon plasma coagulation to treat 28 patients with hemorrhagic radiation-induced proctosigmoiditis. Indications for treatment were anemia (n = 18) and persistent bleeding despite pharmacotherapy (n = 10). Argon flow and electrical power were set at 1.5 L/min and 50 W. The severity of rectal bleeding was graded from 0 to 4 (highest), and hemoglobin levels were recorded before and after treatment. RESULTS Eighty-two therapeutic sessions were performed (median 2.9 sessions per patient). The severity score for rectal bleeding dropped at least 1 point for all but 2 patients, and the mean value decreased from 2.96 to 0.68. Average hemoglobin level increased 1.2 gm/dL (1.9 gm/dL among anemic patients). No serious complications were observed. CONCLUSIONS Argon plasma coagulation appears to be a simple, safe, and effective technique in the management of hemorrhagic radiation-induced proctosigmoiditis.

Abstract
Severe gastrointestinal bleeding is a rare complication of radiation therapy that requires frequent transfusions. This case report describes a patient with severe bleeding from radiation colitis after treatment of bladder cancer. During 5 months of therapy with multiple drugs, the patient needed 26 units of packed red cells. A subsequent hormone therapy consisting of an estrogen-progesterone combination significantly reduced the need for blood transfusions and hospitalization. We conclude that hormones might provide a promising new additional symptomatic therapy for bleeding radiogenic colitis.

Abstract
AIM Our objective was to investigate the effectiveness of hyperbaric oxygenation (HBO) in the treatment of radiation proctitis. The current literature was reviewed with regard to the necessary number of HBO treatments. PATIENTS AND METHODS Two patients with proctitis after pelvic irradiation were treated with 40 and 38 HBO treatments, respectively. Hyperbaric oxygenation was delivered at 240 kPa over 90 min. RESULTS In one patient, proctosigmoidoscopy showed a significant improvement after 40 HBO sessions. The other patient interrupted therapy after 38 HBO treatments without subjective change. The reported number of HBO sessions for a successful treatment of radiation proctitis ranges from 12 to 90. CONCLUSION HBO should be considered before more invasive treatment modalities are performed for radiation proctitis.

Abstract
Radiation proctopathy can be a disabling delayed outcome of radiation therapy directed at pelvic malignancies. Rectal outlet bleeding can be severe enough to result in anemia and transfusion dependency. Bleeding typically develops from 6 months to 1 year after completion of radiation therapy and is caused by friable mucosal angioectasias. Although many approaches to controlling bleeding from chronic radiation proctopathy have been attempted, ranging from topical enema formulations to surgical diversion of the rectum, endoscopic coagulation therapy remains the most effective. This review provides the background issues surrounding the development of chronic bleeding radiation proctopathy and focuses on endoscopic methods of treatment.

Abstract
PURPOSE Treatment of chronic radiation proctitis remains unsatisfactory. Short-chain fatty acids are the preferred energy source for the colonic epithelium. We aimed to determine for the first time whether topical butyric acid enemas relieve symptoms and improve the macroscopic and microscopic findings in chronic radiation proctitis. METHODS A randomized, double-blind, placebo-controlled, cross-over pilot trial compared patients given two weeks of butyric acid enemas (40 mmol) twice per day with those given placebo, with a one-week washout period; 15 patients were randomized and 12 completed both arms of the trial. A total symptom score combined six symptom items per week (rectal pain, episodes of rectal bleeding, amount of blood passed, days with diarrhea, number of stools, and urgency). Symptom, endoscopic, and histologic scores were obtained at the beginning of the study and again at the last week of each treatment arm. RESULTS Total symptom score at baseline (median, 5.5) improved for those patients receiving active treatment (median, 3.5), but compared with placebo (median, 4.5), the change was not significant. Endoscopic appearances were largely unaltered by active treatment. Histology was abnormal in 82 percent of patients receiving placebo compared with 55 percent of those given butyric acid enemas (P = not significant). CONCLUSION Butyric acid enemas do not appear to be superior to placebo in the treatment of chronic radiation proctitis.

Abstract
PURPOSE Our objective was to assess, retrospectively, the efficacy of hyperbaric oxygen treatment in radiation proctitis in all patients who have completed treatment for this disease at the Fremantle Hyperbaric Oxygen Unit. This unit is the only one of its kind in Western Australia. METHODS AND MATERIALS Patients were assessed by a review of hospital records, blood bank records, and clinic review (if this was convenient), and all patients responded to a telephone survey. Patients were questioned regarding radiation proctitis symptoms and the degree to which each had improved. RESULTS Most patients had previously been treated with radiotherapy for prostate carcinoma. Patients with proctitis mainly suffered from bleeding, diarrhoea, incontinence, and pain. In more than half of these patients, symptoms partially or completely resolved after hyperbaric oxygen treatment. CONCLUSION Radiation-induced proctitis is a difficult clinical problem to treat and will probably become more significant with the rising incidence of diagnosis of prostate cancer. Hyperbaric Oxygen should be considered in the treatment of radiation-induced proctitis. Further prospective trials with strict protocol guidelines are warranted.
