Abstract
AIM Pelvic radiotherapy is limited by dose-dependent toxicity to surrounding organs. The aim of this prospective study was to evaluate the efficacy and safety of intrarectal formalin treatment for radiotherapy-induced haemorrhagic proctopathy (RHP) at the Royal Marsden Hospital. METHOD Adult patients were enrolled. Haemoglobin was evaluated before and after formalin treatment. Antiplatelet and/or anticoagulation treatment and administration of transfusion were recorded. The interval between completion of radiotherapy and the first intrarectal 5% formalin treatment was assessed and the dose of radiotherapy was evaluated. Clinical assessment of the frequency and amount of rectal bleeding (rectal bleeding score 1-6) and endoscopic appearance (grade 0-3) were classified. Complications were recorded. RESULTS Nineteen patients were enrolled, comprising 13 men (68%) and 6 women. The mean age was 75 ± 9 years. The median time between completion of radiotherapy and the first treatment was 20 months [interquartile range (IQR) 15 months] and the median dose of radiotherapy was 68 Gy (IQR 14 Gy). Thirty-two procedures were performed (average 1.7 per patient). In total, 9/19 (47%) patients were receiving anticoagulation and/or antiplatelet medication and 5/19 (26%) received transfusion prior to treatment. The mean value of serum haemoglobin before the first treatment was 110 ± 18 g/L and afterwards it was 123 ± 16 g/L (p = 0.022). The median rectal bleeding score before the first treatment was 6 (IQR 0) and afterwards 2 (IQR 1-4; p < 0.001), while the median endoscopy score on the day of first treatment was 3 (IQR 0) compared with 1 (IQR 1-2) on the day of the last treatment 1 (p < 0.001). One female patient with a persistent rectal ulcer that eventually healed (18 months of healing) subsequently developed rectovaginal fistula (complication rate 1/19, 5%). CONCLUSIONS Treatment with intrarectal formalin in RHP is effective and safe.

Abstract
Background Radiation proctitis is a common complication that occurs as a result of radiation therapy used to treat pelvic malignancies. The most common and bothersome symptom resulting from radiation proctitis is rectal bleeding, which can be persistent or recurrent. This study aimed to review our experience and evaluate the efficacy and safety of transcolonoscopic spraying of formalin solution in patients with hemorrhagic radiation proctitis. Methods A total of 37 patients with hemorrhagic radiation proctitis, aged between 48 and 79 years (mean age 62.56 ± 8.48 years), were divided into three cohorts based on the severity of radiation injury. Under direct endoscopic vision, a 4% formalin solution was applied directly to the rectal hemorrhagic mucosa. The patients were followed for a period of over 6 months after receiving treatment, during which the therapeutic effectiveness and occurrence of complications were observed. Results The study resulted in an overall response rate of 89.2% among all patients. The response rates for patients with grades 1-3 were 100, 100, and 66.7%, respectively. Notably, the rate of response among patients with grade 3 radiation injury was significantly lower compared to those with grades 1-2 (p = 0.009). Mild adverse reactions, such as anal pain and tenesmus, were reported in a small number of patients but could be alleviated without any intervention. Conclusion The endoscopic application of formalin solution for the treatment of hemorrhagic radiation proctitis has shown a significant effect, particularly in patients with grades 1-2 radiation injury. The observed effect is superior to that observed in patients with grade 3 radiation injury.

Endorectal formalin instillation or argon plasma coagulation for hemorrhagic radiation proctopathy therapy: a prospective and randomized clinical trial. Gastrointest Endosc 2021; 93:1393-1400. [PMID: 33220297 DOI: 10.1016/j.gie.2020.11.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 11/09/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND AND AIMS Radiotherapy may cause hemorrhagic radiation proctopathy (HRP). For conservative treatment of refractory HRP, argon plasma coagulation (APC) is the first-choice therapy. Endorectal formalin instillation (EFI), in turn, is an attractive treatment option because of its satisfactory results, great availability, and low cost. Nevertheless, comparative studies between these procedures are rather scarce. This study aims to make a prospective and randomized comparison of the outcomes in 2 HRP patient groups treated with either APC or EFI. METHODS Twenty-seven patients (11 women), with a mean age of 67 years (range, 36-83), were randomized to receive either APC (n = 14) or EFI (n = 13). On completion of the treatment, comparisons were made in relation to the baseline for each patient and between groups for endoscopic findings according to the Vienna score and the telangiectasia distribution pattern score (TDP); the impact of radiation proctitis on patients' lives was made according to the modified radiation toxicity score (MRTS) and hemoglobin levels. Number of sessions, duration of therapy, and adverse events were also compared between groups. The endoscopic therapeutic success (ETS) was defined by the absence or only few residual telangiectasias (TDP ≤1) on conclusion. RESULTS An ETS of 92.8% was achieved in patients treated with APC and 92.3% for those treated with EFI (P > .05); there was an MRTS improvement of 85.7% in APC patients and 69.2% in EFI patients (P > .05). Mild adverse events occurred, respectively, in 23% and 28.5% in the EFI and APC groups (P > .05). CONCLUSIONS The study showed that APC and EFI have similar efficacy and a high safety profile for HRP treatment. (Clinical trial registration number: 3.120.353.).

Abstract
Pelvic radiation therapy is an integral component in the treatment of various gastrointestinal, gynecologic, and genitourinary cancers. As survival rates from these malignancies improve, the prevalence of toxicity secondary to pelvic radiation has increased. Gastrointestinal toxicities are the most common complications and greatly impact quality of life. Toxicities can present in acute or late stages; although symptoms may be similar during both, the management may differ. Acute toxicities represent an inflammatory reaction in response to the radiation exposure, whereas late toxicities may arise as a result of small vessel disease, ischemia, and fibrosis. Currently, there are no large clinical trials and only limited guidelines on the management of late gastrointestinal radiation toxicities. Therapy is generally approached in a stepwise manner from medical to endoscopic to surgical methods. Several endoscopic therapies, such as the treatment of radiation proctitis with argon plasma coagulation and dilation of radiation bowel strictures, may prevent the need for surgical intervention, which may be associated with high morbidity and mortality. Given that late toxicities can occur years after radiation therapy, they are often difficult to recognize and diagnose. Successful management of late toxicities requires recognition, an understanding of the underlying pathophysiology, and a multidisciplinary approach. More dedicated research could clarify the prevalence of gastrointestinal pelvic radiation toxicities, permit a better understanding of the efficacy and safety profile of current therapies, and allow for the development of novel therapeutic approaches.

Abstract
Following definitive chemoradiation for anal squamous cell carcinoma (ASCC), patients face a variety of chronic issues including: bowel dysfunction, accelerated bone loss, sexual dysfunction, and psychosocial distress. The increasing incidence of this disease, high cure rates, and significant long-term sequelae warrant increased focus on optimal survivorship care following definitive chemoradiation. In order to establish our survivorship care model for ASCC patients, a multi-disciplinary team of experts performed a comprehensive literature review and summarized best practices for the multi-disciplinary management of this unique patient population. We reviewed principle domains of our survivorship approach: (1) management of chronic toxicities; (2) sexual health; (3) HIV management in affected patients; (4) psychosocial wellbeing; and (5) surveillance for disease recurrence and survivorship care delivery. We provide recommendations for the optimization of survivorship care for ASCC patients can through a multi-disciplinary approach that supports physical and psychological wellness.

Abstract
BACKGROUND This is an updated version of the original Cochrane review published in Issue 5, 2015.Cervical cancer is the fourth most common cancer among women worldwide, with estimated 569,847 new diagnoses and 311,365 deaths per year. However, incidence and stage at diagnosis vary greatly between geographic areas and are largely dependent on the availability of a robust population screening programme. For example, in Nigeria, advanced-stage disease at presentation is common (86% to 89.3% of new cases), whereas in the UK, only 21.9% of women present with International Federation of Gynaecology and Obstetrics (FIGO) stage II+ disease. Women with advanced cancer of the cervix often need palliation for distressing symptoms, such as vaginal bleeding. Vaginal bleeding can be life threatening in advanced disease, with an incidence ranging from 0.7% to 100%. Bleeding is the immediate cause of death in 6% of women with cervical cancer and its management often poses a challenge.Thus, vaginal bleeding remains a common consequence of advanced cervical cancer. Currently, there is no systematic review that addresses palliative interventions for controlling vaginal bleeding caused by advanced cervical cancer. A systematic evaluation of the available palliative interventions is needed to inform decision-making. OBJECTIVES To evaluate the efficacy and safety of tranexamic acid, vaginal packing (with or without formalin-soaked packs), interventional radiology or other interventions compared with radiotherapy for palliative treatment of vaginal bleeding in women with advanced cervical cancer. SEARCH METHODS The search for the original review was run in 23 March 2015, and subsequent searches for this update were run 21 March 2018. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 3) in the Cochrane Library; MEDLINE via Ovid to March week 2, 2018; and Embase via Ovid to March week 12, 2018. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of review articles, and contacted experts in the field. We handsearched citation lists of relevant studies. SELECTION CRITERIA We searched for randomised and non-randomised comparative studies that evaluated the efficacy and safety of tranexamic acid, vaginal packing (with or without formalin-soaked packs), interventional radiology or other interventions compared with radiotherapy techniques for palliative treatment of vaginal bleeding in women with advanced cervical cancer (with or without metastasis), irrespective of publication status, year of publication or language in the review. DATA COLLECTION AND ANALYSIS Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. We found no studies for inclusion and, therefore, we analysed no data. MAIN RESULTS The search strategy identified 1522 unique references of which we excluded 1330 on the basis of title and abstract. We retrieved the remaining 22 articles in full, but none satisfied the inclusion criteria. We identified only observational data from single-arm studies of women treated with formalin-soaked packs, interventional radiology or radiotherapy techniques for palliative control of vaginal bleeding in women with cervical cancer. AUTHORS' CONCLUSIONS Since the last version of this review we found no new studies. There is no evidence from controlled trials to support or refute the use of any of the proposed interventions compared with radiotherapy. Therefore, the choice of intervention will be based on local resources. Radiotherapy techniques for managing vaginal bleeding are not readily available in resource-poor settings, where advanced cases of cervical cancer are predominant. Thus, this systematic review identified the need for a randomised controlled trial assessing the benefits and risks of palliative treatments for vaginal bleeding in women with advanced cervical cancer.

Abstract
BACKGROUND To investigate the effectiveness of topical application of 4% formaldehyde as a minimally invasive treatment of rectal bleeding due to chronic radiation proctitis (CRP) under direct vision of electronic colonoscope. METHODS The clinical data of 13 CRP patients complicated with ≥ grade II bleeding admitted to our hospital between January 2003 and December 2018 were retrospectively analyzed. Under the guidance of electronic colonoscope, 4% formaldehyde combined with 5-aminosalicylic acid (5-ASA) suppositories was topically applied. Patients were followed up for two months after treatment, and the therapeutic effectiveness was observed and analyzed. RESULTS The rectal bleeding due to CRP was markedly reduced after topical application of 4% formaldehyde under colonoscope in all 13 patients. The bleeding stopped after one treatment session in 11 patients and after the second session in 2 patients. 5-ASA was also applied along with the use of 4% formaldehyde. The therapeutic effectiveness was satisfactory during the 1- and 2-month follow-up period. CONCLUSION Topical application of 4% formaldehyde under the direct vision of colonoscope as a minimally invasive treatment for CRB-induced bleeding is a simple, effective, affordable, and repeatable technique without obvious complications, which deserves further exploration and promotion.

Abstract
Radiation proctitis is radiation-induced rectal mucositis, occurring as a result of radiation therapy for various pelvic malignancies. The management of radiation proctitis is challenging as guidelines are not currently available, and studies of the various treatment modalities are limited. There are various medical, endoscopic, and surgical measures for treating chronic radiation proctitis. Medical options such as anti-inflammatory agents, antioxidants, formalin application, and hyperbaric oxygen may improve bleeding related to chronic radiation proctitis. Endoscopic measures such as argon plasma coagulation are effective and safe. Surgery is considered for refractory or severe cases. A review and discussion of the different treatment modalities is presented.

Abstract
PURPOSE: To evaluate histopathologically the radioprotective effect of L-carnitine on the colonic mucosa in rats undergoing abdominopelvic irradiation. METHODS: Thirty-two rats were randomly assigned to four experimental groups: intraperitoneal administration of normal saline (group 1) or L-carnitine (300 mL/kg; group 2), followed in groups 3 and 4, respectively, by one dose of abdominopelvic radiation (20 Gy) 30 min later. Rats were sacrificed 5 days after radiation, and their descending colons were resected for histopathological evaluation of the presence and severity of damage. RESULTS: Average damage scores did not differ significantly between groups 1 and 2 (0.13 ± 0.35 and 0.25 ± 0.46, respectively); the group 3 score was highest (10.25 ± 0.71), and the group 4 score (3.63 ± 1.41) was significantly lower than that of group 3 (both p = 0.0001). Pre-radiation L-carnitine administration significantly reduced mucosal thinning, crypt distortion, reactive atypia, inflammation, cryptitis, and reactive lymph-node hyperplasia (all p < 0.01). CONCLUSIONS: L-carnitine had a radioprotective effect on rat colonic mucosa. L-carnitine use should be explored for patients with gastrointestinal cancer, who have reduced serum L-carnitine levels.

Abstract
PURPOSE This study was designed to assess the efficacy and outcomes of argon plasma coagulation (APC) in the management of chronic radiation proctitis after conventionally fractionated, dose-escalated radiation therapy (≥7560 cGy). METHODS AND MATERIALS We retrospectively reviewed the charts on all patients treated with external beam radiation therapy (minimum dose, 7560 cGy) for histologically confirmed prostate cancer at our institution from 2003 to 2011. Five hundred patients met these criteria; of these, 35 patients (7.0%) developed radiation proctitis necessitating intervention with APC. Indications for APC treatment were either the need for blood transfusions resulting from proctitis-related anemia or refractory bleeding despite medical management. RESULTS The median follow-up from the completion of radiation treatment was 78 months (range, 19-129) and the median follow up from the most recent APC treatment was 56 months (range, 3-112). Fifteen men (42.9%) needed blood transfusions because of proctitis-related anemia. For 19 patients (54.3%), bleeding was controlled after 1 or 2 treatments. Eventual bleeding control was obtained in 30 patients (85.7%). The median number of sessions per patient was 2 (range, 1-13). Post-APC ulceration was noted in 8 cases (22.9%). Two patients (5.7%) developed colovesicular fistulas, with 1 patient dying from this complication. A short interval between treatments (≤35 days) was associated with an increased risk of ulcer or fistula formation. CONCLUSIONS APC is an effective treatment for patients with medically refractive radiation proctitis after dose-escalated radiation therapy, frequently controlling bleeding after only one or two sessions. However, rectal ulceration is a common complication, along with a small risk of life-threatening toxicity.

Abstract
Chronic haemorrhagic radiation proctitis (CHRP) is a difficult problem faced by the patients following radiation for pelvic malignancy. There is no standard treatment for this condition, but many methods of treatment are available. The aim of this study was to review the literature to see whether there is an improvement in the available evidence in comparison with previously published systematic reviews in treating patients with CHRP. The PubMed/Medline database and Google Scholar search was selectively searched. Studies, which treated patients with rectal bleeding due to chronic radiation proctitis or CHRP, were included. Seventy studies were finally selected out of which 14 were randomized controlled clinical trials. Though these studies could not be compared, it could be seen that there was an improvement in the methodology of the studies. There was an objective assessment of symptoms, signs and an objective assessment of outcomes. But, still, there were only a few studies that looked into the quality of life following treatment of CHRP. To increase recruitment to trials, a national registry of cases with established late radiation toxicity would facilitate the further improvement of such studies. Some of the conclusions that could be reached based on the available evidence are 4% formalin should be the first line treatment for patients with CHRP. Formalin and argon plasma coagulation (APC) are equally effective, but formalin is better for severe disease. Refractory patients, not responding to formalin or APC, need to be referred for hyperbaric oxygen therapy or surgery. Radio-frequency ablation is a promising modality that needs to be studied further in randomized trials.

Abstract
Although formalin instillation has been proven to be an effective treatment of hemorrhagic radiation proctitis, different tech niques with varying success rates have been reported. The aim of this study was to assess our experience with formalin instillation for the treatment of radiation proctitis. After Institutional Review Board approval, all patients who presented with radiation proctitis and were treated with 4% formalin instillation were identified from a prospective database. Techniques of instillation were as follows: a formalin-soaked sponge stick was applied via a proctoscope (SS) and placed at each quadrant with a mean contact of 2.5 minutes (range, 0.5-3 minutes), or the formalin solution was introduced through a proctoscope in aliquots for a total of 350 to 400 mL irrigation (IR), with a mean contact time of 30 seconds in each aliquot. The patients were divided into two groups according to the method of formalin instillation and their outcomes were compared. Between March 1995 and September 2003, 21 patients who underwent formalin treatment were identified: 17 patients were in the SS and 4 patients were in the IR group. The mean age was 74.8 6.4 years and 70.5 6.8 years and the male/female ratio was 16:1 and 3:1 in the SS and IR groups, respectively. Indications for radiation therapy were prostate cancer in 19 patients: 16 (95.1%) SS patients and 3 (75%) IR patients. Four (23.5%) patients in the SS group were receiving anticoagulants or antiplatelet medications before the procedure. The mean duration of bleeding before formalin instillation was 11.7 months (range, 2-48 months) in the SS and 10.5 months (range, 7-12 months) in the IR group. Sixteen (94.1%) patients in the SS and 4 (100%) in the IR group had previous treatments for radiation proctitis, including hydrocortisone enema, 5-aminosalicylate mesalamine, and endoscopic coagulation. Eight (47.1%) patients in the SS and 2 (50%) in the IR group received a preprocedural blood transfusion, and 1 patient in the SS group required a blood transfusion after the formalin instillation. This patient subsequently underwent restorative proctosigmoidectomy because of persistent bleeding. The mean length of the procedure was 27.1 10.8 minutes in the SS group and 22.5 6.5 minutes in the IR group. The bleeding was successfully stopped on the first attempt in 14 patients (82.4%) in the SS group and 3 (75%) in the IR group. The instillation was repeated in 1 patient (5.9%) in the SS group and in 1 (25%) in the IR group. Four patients (23.5%) in the SS group experienced rectal pain after the procedure. One patient (5.9%) developed a new onset of fecal incontinence, while another (5.9%) had anococcygeal pain accompanied by worsening of fecal incontinence. One patient (25%) in the IR group developed acute colitis consistent with formalin instillation, which was managed by intravenous antibiotics. The patients were followed for a mean of 10 months (range, 1 to 38 months). Formalin instillation is effective in controlling refractory hemorrhage secondary to radiation proctitis.

Abstract
OBJECTIVE The purpose of this study was to give an overview of the measures used to prevent chronic radiation proctitis (CRP) and to provide an algorithm for the treatment of CRP. METHODS Medical literature databases including PubMed and Medline were screened and critically analyzed for relevance in the scope of our purpose. RESULTS CRP is a relatively frequent late side effect (5-20%) and mainly dependent on the dose and volume of irradiated rectum. Radiation treatment (RT) techniques to prevent CRP are constantly improving thanks to image-guided RT and intensity-modulated RT. Also, newer techniques like protons and new devices such as rectum spacers and balloons have been developed to spare rectal structures. Biopsies do not contribute to diagnosing CRP and should be avoided because of the risk of severe rectal wall damage, such as necrosis and fistulas. There is no consensus on the optimal treatment of CRP. A variety of possibilities is available and includes topical and oral agents, hyperbaric oxygen therapy, and endoscopic interventions. CONCLUSIONS CRP has a natural history of improving over time, even without treatment. This is important to take into account when considering these treatments: first be conservative (topical and oral agents) and be aware that invasive treatments can be very toxic.

Abstract
Radiation therapy is a widely utilized treatment modality for pelvic malignancies, including prostate cancer, rectal cancer, and cervical cancer. Given its fixed position in the pelvis, the rectum is at a high risk for injury secondary to ionizing radiation. Despite advances made in radiation science, up to 75% of the patients will suffer from acute radiation proctitis and up to 20% may experience chronic symptoms. Symptoms can be variable and include diarrhea, bleeding, incontinence, and fistulization. A multitude of treatment options exist. This article summarizes the latest knowledge relating to radiation proctopathy focusing on the vast array of treatment options.

Abstract
BACKGROUND Cervical cancer is the second most common cancer among women worldwide, with around 500,000 new diagnoses and 273,000 deaths per year. However, incidence and stage at diagnosis vary greatly between geographic areas and are largely dependent on the availability of a robust population screening programme. For example, in Nigeria, advanced-stage disease at presentation is common (86% to 89.3% of new cases), whereas in the UK, only 21.9% of women present with International Federation of Gynaecology and Obstetrics (FIGO) stage II+ disease. Women with advanced cancer of the cervix often need palliation for distressing symptoms, such as vaginal bleeding. Vaginal bleeding can be life threatening in advanced disease, with an incidence ranging from 0.7% to 100%. Bleeding is the immediate cause of death in 6% of women with cervical cancer and its management often poses a challenge.Thus, vaginal bleeding remains a common consequence of advanced cervical cancer. Currently, there is no systematic review that addresses palliative interventions for controlling vaginal bleeding caused by advanced cervical cancer. A systematic evaluation of the available palliative interventions is needed, to inform decision-making. OBJECTIVES To evaluate the efficacy and safety of tranexamic acid, vaginal packing (with or without formalin-soaked packs), interventional radiology or other interventions compared with radiotherapy for palliative treatment of vaginal bleeding in women with advanced cervical cancer. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 2, 2015; the Cochrane Gynaecological Cancer Group Trials Register; MEDLINE from 1980 to March week 3, 2015 and EMBASE from 1980 to February week 12, 2015. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of review articles and contacted experts in the field. We handsearched citation lists of relevant studies. SELECTION CRITERIA We searched for randomised and non-randomised comparative studies that evaluated the efficacy and safety of tranexamic acid, vaginal packing (with or without formalin-soaked packs), interventional radiology or other interventions compared with radiotherapy techniques for palliative treatment of vaginal bleeding in women with advanced cervical cancer (with or without metastasis), irrespective of publication status, year of publication or language in the review. DATA COLLECTION AND ANALYSIS Two review authors independently assessed whether potentially relevant studies met the inclusion criteria. We found no studies were identified for inclusion and, therefore, we analysed no data. MAIN RESULTS The search strategy identified 1335 unique references of which 1160 were excluded on the basis of title and abstract. We retrieved the remaining 22 articles in full, but none satisfied the inclusion criteria. We identified only observational data from single-arm studies of women treated with formalin-soaked packs, interventional radiology or radiotherapy techniques for palliative control of vaginal bleeding in women with cervical cancer. AUTHORS' CONCLUSIONS There is no evidence from controlled trials to support or refute the use of any of the proposed interventions compared with radiotherapy. Therefore, the choice of intervention will be based on local resources. Radiotherapy techniques for managing vaginal bleeding are not readily available in resource-poor settings, where advanced cases of cervical cancer are predominant. Thus, this systematic review identified the need for a randomised controlled trial assessing the benefits and risks of palliative treatments for vaginal bleeding in women with advanced cervical cancer.

Abstract
Chronic proctitis refers to persistent or relapsing inflammation of the rectum, which results from a wide range of etiologies with various pathogenic mechanisms. The patients may share similar clinical presentations. Ulcerative proctitis, chronic radiation proctitis or proctopathy, and diversion proctitis are the 3 most common forms of chronic proctitis. Although the diagnosis of these disease entities may be straightforward in the most instances based on the clinical history, endoscopic, and histologic features, differential diagnosis may sometimes become problematic, especially when their etiologies and the disease processes overlap. The treatment for the 3 forms of chronic proctitis is different, which may shed some lights on their pathogenetic pathway. This article provides an overview of the latest data on the clinical features, etiologies, diagnosis, and management of ulcerative proctitis, chronic radiation proctopathy, and diversion proctitis.

Abstract
PURPOSE The purposes of this analysis are to report a modern series of severe gastrointestinal toxic effects after definitive chemoradiotherapy in the treatment of locally advanced cervical cancer at our institution and to review the existing literature on factors that contribute to toxic effects and preventive strategies and management. METHODS Our institution's cervical cancer cohort was evaluated for patients with late grade 3 to 4 gastrointestinal toxic effects who were retrospectively reviewed for clinical or dosimetric parameters that could have contributed to late toxic effects. A review of the published literature was performed to identify factors associated with late toxic effects, prophylactic agents, and corrective therapy. FINDINGS Five of 85 patients were identified as having late grade 3 to 4 gastrointestinal toxic effects with a median follow-up of 13.3 months. Two of 5 patients developed late grade 3 toxic effects, and 3 of 5 developed late grade 4 toxic effects. Three of the 5 patients reviewed ultimately required permanent colostomies. Cumulative median dose (in equivalent dose in 2-Gy fractions) of clinical target volume to the hottest 90% was 107.2 Gy, rectal dose to the hottest 2 cc (D2cc) was 81.7 Gy, sigmoid D2cc was 61.7 Gy, and bladder D2cc was 79.5 Gy. No patient had evidence of disease recurrence in the pelvis. One patient developed oligometastatic disease in the suprarenal gland and was successfully salvaged with adrenalectomy. IMPLICATIONS Despite its risk of toxic effects, intracavitary brachytherapy remains a critical component of the treatment of locally advanced cervical cancer. Even with modern radiotherapy planning and delivery techniques, extra attention is warranted to continue to strive for optimal outcomes.

Abstract
PURPOSE Chronic hemorrhagic radiation proctopathy is not uncommon after radiotherapy for cervical carcinoma. The outcomes of several treatments have been variable. Many studies demonstrate that topical treatment with 4 % formalin is effective and safe. However, a nonrandomized control study showed a high response rate and good tolerance in chronic radiation proctopathy patients treated with 10 % formalin. The optimal concentration of formalin therefore remains unclear. METHODS To compare the effectiveness and safety of 4 and 10 % formalin for the treatment of chronic hemorrhagic radiation proctopathy, a prospective trial was conducted at the Department of Gynecology of the Affiliated Hospital of Binzhou Medical College from January 2009 to December 2012. One hundred and twenty patients with chronic hemorrhagic radiation proctopathy following radiotherapy for cervical carcinoma were recruited and randomized to receive 4 or 10 % formalin. A standard protocol was followed for formalin application. Symptom and rectoscopy scores were evaluated before and at 12 weeks after treatment. RESULTS In the 4 % formalin group, 49 (86.0 %) and 53 (91.4 %) patients showed an improvement in symptom score and rectoscopy score, respectively (P = 0.36). Symptom and rectoscopy scores decreased significantly after treatment in both the 4 % formalin group and the 10 % formalin group (P < 0.001). Symptom score was correlated with rectoscopy score (P < 0.001). More patients in the 10 % group suffered treatment-related complications than did those in the 4 % group (P = 0.03). CONCLUSIONS For the treatment of chronic hemorrhagic radiation proctopathy, 4 % should be the preferred formalin concentration.

Abstract
BACKGROUND Chronic radiation proctitis (CRP) occurs up to 20 % of patients after pelvic radiotherapy, with rectal bleeding as the main presenting complaint. Radiofrequency ablation (RFA) has recently been used in the management of Barrett's esophagus, but its efficacy in CRP has to be studied. The aim of this case series was to describe four cases of patients with CRP treated with RFA that demonstrate the efficacy and safety of the technique. METHODS All the procedures were performed with HALO 90 or HALO 90 Ultra ablation catheter fitted on the distal end of a standard flexible endoscope. For each patient, the severity of symptoms was assessed at baseline and after the last treatment session. RESULTS At least two sessions of RFA (maximum 4) were necessary, at three-month intervals, to completely control the symptoms. No major complications were observed. CONCLUSIONS RFA was effective and safe for control bleeding in this case series. Adequately powered randomized controlled trials are needed to establish the safety and efficacy of RFA for CRP.

Abstract
Radiation damage to the rectum following radiotherapy for pelvic malignancies can range from acute dose-limiting side effects to major morbidity affecting health-related quality of life. No standard guidelines exist for diagnosis and management of radiation proctitis. This article reviews the definitions, staging, and clinical features of radiation proctitis, and summarizes the modalities available for the treatment of acute and chronic radiation proctitis. Because of the paucity of well-controlled, blinded, randomized studies, it is not possible to fully assess the comparative efficacy of the different approaches to management. However, the evidence and rationale for use of the different strategies are presented.

Abstract
AIM Rectal bleeding may occur late after radiotherapy for prostate or bladder cancer, particularly when given by external beam, due to radiotherapy-induced haemorrhagic telangiectasia (RIHT). We present the results of trans-anal rectoscopic ball diathermy (TARD) for RIHT. METHOD Data were collected from patients who received TARD for RIHT. The diagnosis was made during endoscopic examination. Treatment involved discretely spaced spot monopolar diathermy coagulation of the rectal mucosa to the affected areas. RESULTS Thirteen patients [median age 76 (69-80) years] underwent TARD for RIHT between 2005 and 2008. All presented late with rectal bleeding following radiotherapy for prostate or bladder cancer. Eight were treated as a day case, four remained in hospital for one night and one was hospitalized for 2 days. There was no mortality. Eleven patients achieved excellent symptomatic control requiring no further treatment at a median follow-up of 20 (3-36) months. One patient underwent further TARD for recurrence. One patient complained of severe anorectal pain of no obvious cause and one developed constipation. CONCLUSION Trans-anal rectoscopic ball diathermy (TARD) is a safe and effective treatment for patients with rectal bleeding due to RIHT.

Abstract
INTRODUCTION Bleeding is a common complication of proctitis secondary to radiotherapy of pelvic tumours. Between 5 and 10% may become severe and refractory to topical and endoscopic treatment. Experience with the application of 4% formaldehyde is presented. PATIENTS AND METHOD A retrospective and descriptive study was performed on a patient cohort with severe radiation proctitis admitted to the Hospital Universitario Donostia between January 2003 and September 2009. All patients were diagnosed by colonoscopy and admitted due to the severity of their treatment. Both 4% formaldehyde and the gauze technique were used, as well as using enemas, in cases refractory to topical and endoscopic treatment with argon. The technique was performed in theatre with regional anaesthetic. Clinical and endoscopic follow up was carried out. RESULTS The study included 25 males (73.5%) and 9 women (26.5%), with a mean age of 69 years (32-80) who had rectal bleeding due to radiation proctitis and required admission. All treatments failed in 6 (28.5%) patients, and 4% formaldehyde was used, with a complete response to the bleeding in all 6 patients, with 3 cases requiring one session, and the 3 others 2 sessions. The gauze technique was used in 4 patients and another 2 were given a formaldehyde enema due to the presence of stenosis. Pain appeared as the main complication in 2 (33.3%) patients. The median follow up was 60 months (interquartile range 26 to 67 months). CONCLUSIONS The use of 4% formaldehyde in bleeding due to radiation proctitis is an effective, easy to reproduce technique, with a low morbidity.

Abstract
BACKGROUND Several treatments have been described for hemorrhagic radiation proctitis. The treatment outcomes are variable. Colonic irrigation and oral antibiotics for hemorrhagic radiation proctitis have been recently reported to be a novel and promising therapeutic approach. However, a comparative study of this treatment has never been investigated. OBJECTIVE This study aimed to compare colonic irrigation and oral antibiotics (irrigation group) versus 4% formalin application (formalin group) for treatment of hemorrhagic radiation proctitis. DESIGN This was a randomized controlled trial. SETTING This study was conducted in a tertiary care/university-based hospital. PATIENTS Fifty patients with hemorrhagic radiation proctitis were randomly assigned to each treatment group (n = 25). INTERVENTIONS For individuals allocated to the irrigation group, daily self-administered colonic irrigation with 1 L of tap water and a 1-week period of oral antibiotics (ciprofloxacin and metronidazole) were prescribed. For individuals allocated to the formalin group, 4% formalin application for 3 minutes was performed. MAIN OUTCOME MEASURES Patients' symptoms and the endoscopic findings of each group were collected. Patient satisfaction was surveyed. The outcomes were evaluated at 8 weeks after the initiation of treatment. RESULTS There was a significant improvement in rectal bleeding and bowel frequency in both treatment groups, but significant improvement in urgency, diarrhea, and tenesmus was demonstrated only in the irrigation group. The comparative study between 2 treatments revealed greater improvement in rectal bleeding, urgency, and diarrhea in the irrigation group. Twenty of 24 patients in the irrigation group and 10 of 23 patients in the formalin group were satisfied with the treatment. LIMITATIONS This trial cannot illustrate whether the antibiotics and the irrigation were equally important because of the limitation of a 2-armed design. CONCLUSIONS The treatment with colonic irrigation and oral antibiotics appears to be more effective than 4% formalin application for hemorrhagic radiation proctitis treatment and achieves higher patient satisfaction.

Abstract
PURPOSE Radiotherapy is one of the important treatment modalities for tumors of pelvic organs. The fixed location of the rectum and its anatomic relationship with other pelvic organs makes it prone to radiation injury resulting in chronic radiation proctopathy in 5% to 20% of patients. Endothelial dysfunction has been associated with a number of pathophysiological processes. Endothelial cells synthesize and release various factors that regulate angiogenesis, inflammatory responses, hemostasis, as well as vascular tone and permeability. METHODS Rectum tissue samples from 20 patients with established chronic radiation proctopathy were analysed for the expression of genes related to oxidative stress, tissue hypoxia, angiogenesis, and inflammation [endoglin (ENG), activin receptor-like kinase 1 (ALK1), platelet endothelial cell adhesion molecule 1 (PECAM), vascular endothelial growth factor (VEGF), fibroblast growth factor 2 (FGF2), hypoxia-inducible factor 1 (HIF-1), and interleukin-1 beta (IL-1β)]. RESULTS Overexpression of HIF-1, VEGF, FGF2, and IL-1β was detected in affected tissue. For the first time, a significant suppression of activin receptor-like kinase 1 and ENG could be revealed. CONCLUSION The data provided here allow further insight into the pathogenesis of radiation-induced rectum injury. Radiation-induced damage is not confined to a single event but involves complex signaling between different pathways, enhancing and maintaining the processes that lead to mucosal damage. The results indicate that postradiation tissue hypoxia is critical for fibrosis, which involves changes in the expression of profibrotic and angiogenic factors in rectal tissue.

Abstract
AIM Radiation-induced haemorrhagic proctitis is not uncommon after radiotherapy for pelvic malignancy. Various treatments have been described. Recurrent bleeding and subsequent complications associated with treatment have been reported. Colonic irrigation has been used to treat defaecation disorders; however, it has not been used to treat radiation-induced proctitis. METHOD A pilot study was undertaken of 12 patients with haemorrhagic radiation proctitis after radiotherapy. Four patients had had cervical cancer, five had uterine cancer, one had prostatic cancer, one had vesical cancer and one had vaginal cancer. Daily self-administered colonic irrigation with tap water and a 1-week period of oral antibiotics (ciprofloxacin and metronidazole) were prescribed. RESULTS The median dose of radiation given was 54 (50-70) Gy. The median interval from radiation to the development of haemorrhagic proctitis was 26 (8-44) months. The median duration of symptomatic rectal haemorrhage prior to treatment was 8 (1-48) months. There was a significant improvement in rectal bleeding after treatment with colonic irrigation and oral antibiotic administration, accompanied by an improvement in bowel frequency and urgency, and diarrhoea. There were no complications. The majority of the patients (11/12) were satisfied with the treatment. The five patients who had previously undergone formalin therapy preferred the treatment regimen used in this study. CONCLUSION The preliminary results of colonic irrigation and oral antibiotics indicate that this treatment is safe and effective for radiation-induced proctitis. Further study is warranted.

Abstract
A retite actínica hemorrágica é um quadro grave que pode ocorrer em qualquer paciente submetido à radioterapia pélvica, por vezes, sendo necessária terapia transfusional e internação hospitalar. A abordagem terapêutica ainda é bastante controversa. Tanto para o tratamento inicial como para casos refratários, uma das opções é a aplicação de formalina. Este método é barato, facilmente disponível, de simples execução e eficaz no controle da hemorragia. Os autores relatam dois casos de retite actínica hemorrágica de pacientes tratados com instilação de formalina endoluminal, e sua eficácia terapêutica e complicações são discutidas

Abstract
Radiation therapy is commonly utilized as a major component in the treatment of pelvic malignancy. Unfortunately, secondary toxicity to the lower gastrointestinal tract can occur. This most commonly affects the rectum, although injuries to the colon and small intestine are not uncommon. The presentation can be acute or chronic, and different mechanisms are responsible for each. Symptomatology is quite variable but can result in significant compromise for the patient. Numerous preventive and treatment strategies have been applied to this disease process. This article presents a summary of the current knowledge regarding radiation injury to the lower gastrointestinal tract with special emphasis on treatment options for radiation proctitis.

Abstract
Platelet transfusion therapy is the standard of care for thrombocytopenic patients with hemato-oncological disorders and bone marrow failure states due to intensive chemoradiotherapy. Guidelines to lower triggers for prophylactic and therapeutic transfusions are being developed based on better levels of evidence. The optimum transfusion dose, the choice of platelet concentrate and transfusion interval pose a challenge to balance scientific advances with cost-effective strategies. Platelet refractoriness requires "matched" platelets and is a difficult to treat phenomenon. Pathogen inactivation is a crucial issue in view of susceptibility of platelet concentrates to bacterial contamination. This article reviews the current developments and challenges in optimizing platelet transfusion therapy.

Abstract
The present patient developed a severe rectal ulcer more than 1 month after having received external beam radiation therapy for prostate cancer. Surveillance endoscopy every 3 months demonstrated healing of this rectal ulcer using a novel therapy. He was given enemas with ecabet sodium, which provides physical protection and promotes healing by increasing prostaglandin E(2), and this process induced squamous metaplasia that halted the progression of the ulcer of radiation proctitis as a late-phase reaction. Intrapapillary capillary loops were visualized with magnified narrow band imaging at the healing ulcer site as seen via the esophagus and, moreover, demonstrated histologically.

Abstract
The incidence of radiation-induced chronic hemorrhagic proctitis is less than 10 to 20%. The onset of this proctitis is delayed relative to the radiation therapy and generally develops from 6 to 24 months later. There are numerous predisposing factors, the most important of which is the radiation therapy dose: risk increases exponentially above 40-45 Gy. Its pathophysiology involves progressive obliterating endarteritis and transmural interstitial fibrosis, which induce chronic ischemia that is irreversible and progressive during the years after radiation therapy. Its diagnosis depends most often on the combination of clinical history and typical endoscopic appearance (congestive mucosa and/or telangiectases). Topical administrative of sucralfate or corticosteroids as well as argon plasma coagulation, with formalin treatment if necessary, provides relief for most patients.

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
OBJECTIVE Topical formalin has been used as an effective treatment for haemorrhagic radiation proctitis. In the course of reviewing our experience with this modality, we identified two patients who developed anorectal cancer during the follow-up period. METHOD From 2001 to 2005, 49 patients who received pelvic radiation for treatment of prostate, rectal or endometrial cancer subsequently developed haemorrhagic radiation proctitis. Four percent formalin was applied in the office setting under direct visualization with a rigid proctoscope and without sedation. Response to treatment was then reviewed. RESULTS Seventy-eight per cent of patients reported a complete response to formalin application. Only 14% were refractory to formalin treatment. Two patients subsequently presented with anorectal cancer. CONCLUSION Topical formalin application in the outpatient setting appears to be an effective first-line treatment for haemorrhagic radiation proctitis. We report the first cases of anorectal cancer which developed subsequent to formalin application. Pelvic irradiation is known to increase the risk of developing a second malignancy, therefore it is impossible to determine what, if any, role formalin application played in the development of the second malignancies.

Abstract
AIM: To evaluate the prevalent topical therapeutic modalities available for the treatment of acute radiation proctitis compared to formalin.
METHODS: A total of 120 rats were used. Four groups (n = 30) were analyzed with one group for each of the following applied therapy modalities: control, mesalazine, formalin, betamethasone, and misoprostol. A single fraction of 17.5 Gy was delivered to each rat. The rats in control group rats were given saline, and the rats in the other three groups received appropriate enemas twice a day beginning on the first day after the irradiation until the day of euthanasia. On d 5, 10, and 15, ten rats from each group were euthanized and a pathologist who was unaware of treatment assignment examined the rectums using a scoring system.
RESULTS: The histopathologic scores for surface epithelium, glands (crypts) and lamina propria stroma of the rectums reached their maximum level on d 10. The control and formalin groups had the highest and mesalazine had the lowest, respectively on d 10. On the 15th d, mesalazine, betamethasone, and misoprostol had the lowest scores of betamethasone.
CONCLUSION: Mesalazine, betamethasone, and misoprostol are the best topical agents for radiation proctitis and formalin has an inflammatory effect and should not be used.

Abstract
BACKGROUND Between 2 and 5% of patients undergoing pelvic radiotherapy develop chronic radiation proctopathy, occurring as a result of damage to the rectal mucosa during the treatment. Rectal bleeding of varying severity can occur as a consequence. There have been no formal trials of treatment for haemorrhagic radiation proctopathy and a variety of methods are currently used. AIM In a retrospective study of 20 patients treated at a single centre, we assessed the efficacy of small volume topical formalin instillation to control bleeding from radiation proctopathy. METHOD Patients were treated by a single operator using 20 mL of a 5% solution of formalin instilled into the rectum via a flexible sigmoidoscope for 3 min. Patients were followed up for an average of 22.7 months (range: 2-69). RESULTS A single session of formalin treatment was effective in 13 of 20 (65%) patients and a further four (20%) patients responded to a second treatment. No complications of the treatment was identified. CONCLUSION Small volume formalin instillation therapy appears to be safe and effective in the context of haemorrhagic radiation proctopathy. The technique is simple, inexpensive, quick and requires no sedation. We suggest that it should be considered as a first line for patients presenting with this distressing condition.

Abstract
PURPOSE This prospective study evaluated the efficacy and safety of local formalin application in chronic refractory radiation-induced hemorrhagic proctitis. METHODS All patients were treated under anesthesia by direct application of 4 percent formalin to the affected rectal areas. RESULTS The study included 33 patients (17 women) and was conducted between January 1994 and December 2001. There were 11 anal cancers (33 percent), 11 prostate cancers, 9 cervical or endometrial cancers, 1 bladder cancer, and 1 rectal cancer. The mean number of daily rectal bleeds was 2.7 (range, 0.5-15). Nineteen patients (58 percent) were blood transfusion dependent. Twenty-three patients had only one formalin application and 10 patients required a second application because of the persistent bleeding. The treatment was effective in 23 cases (70 percent): 13 patients had complete cessation of bleeding and 10 patients had only minor bleeding. Six anal or rectal strictures occurred: 4 patients had been treated for anal cancer (36 percent) and 2 patients had been treated for other cancers (9 percent). None of the strictures was malignant. Anal incontinence worsened in 5 patients of the 11 who had been treated for anal cancer (45 percent) and occurred in 4 of the 22 other patients (18 percent). CONCLUSION Formalin application is an effective treatment for chronic radiation-induced hemorrhagic proctitis. However, local morbidity is not negligible. This result may be related to the high proportion of anal cancers in the series. In our opinion, therefore, formalin application should be reserved for severe hemorrhagic proctitis refractory to medical treatment and should be thoroughly discussed in cases of anorectal radiation-induced stricture, prior anal incontinence, or treated anal cancer.

Abstract
AIMS We evaluate prospectively effectiveness, tolerance, predictive factors of failure and complications of argon plasma coagulation (APC) in the treatment of hemorrhagic radiation proctitis (HRP). PATIENTS AND METHODS Twenty-seven patients were treated by APC for HRP. Eight patients needed blood transfusion before APC. Six patients were anti-coagulated and one had severe thrombocytopenia. APC was performed without sedation in 25/27 patients. Before APC treatment, bowel preparation was performed by enema (n = 19 sessions), polyethylene glycol or sodium phosphate (n = 53 sessions). APC treatment was performed every 5 weeks. Effectiveness of APC was based on clinical and endoscopic score and biological status before and after APC treatment. RESULTS The mean follow-up was 13.6 months (range, 3-31 months). After one to seven sessions of APC (average, 2.66 sessions), twenty-five patients (92%) had no recurrence of bleeding. The bleeding score decreased from 3.03 to 0.42 (P < 0.001) and the endoscopic score from 3.08 to 0.73 (P < 0.001). Out of the eight patients requiring blood transfusion prior to APC sessions, only one required blood transfusion after APC (P < 0.05). One late relapse was observed and successfully re-treated by APC. Side effects were anal or rectal pain (n = 3) and vagal symptoms (n = 2). Three colonic explosions occurred, with perforation leading to surgery in one case. The incidence of bowel explosion was higher after local preparation (3/19 sessions) compared with oral preparation (0/53 sessions) (P < 0.05). No stricture due to APC appeared, even if telangiectasias coagulated during a session were circumferential. CONCLUSION Coagulation by APC is an effective and safe treatment of HRP if a complete cleansing preparation is performed to avoid explosion.

Abstract
BACKGROUND AND AIMS Management of haemorrhagic radiation proctitis remains controversial. Both endoscopically delivered argon plasma coagulation and rectal administration of formalin have been recommended. We evaluated the efficacy of argon plasma coagulation according to endoscopic severity of radiation proctitis. PATIENTS AND METHODS Fourteen patients treated with argon plasma coagulation for rectal bleeding due to radiation proctitis were reviewed. Patients were classified with a new endoscopic score for haemorrhagic radiation proctitis, comprising three factors: telangiectasia distribution, surface area involved, and presence of fresh blood. Seven patients were categorised as having grade A (mild), four grade B (moderate), and three grade C (severe) radiation proctitis. Rectal bleeding was assessed pre- and post-treatment using a five-point bleeding scale. RESULTS All patients with grade A and B radiation proctitis were treated successfully by argon plasma coagulation (mean 1.5 sessions). In one patient with grade C radiation proctitis argon plasma coagulation was successful after four sessions, but in the other two patients bleeding could not be controlled; a subsequent single formalin administration was successful in both. Overall in 12 patients (85.7%) bleeding ceased or improved significantly. The mean rectal bleeding scale reduced significantly from 2.6 to 0.9. One patient treated with argon plasma coagulation developed an asymptomatic rectosigmoid stenosis. CONCLUSION Argon plasma coagulation is a simple, safe and efficacious therapy for mild/moderate radiation proctitis. In patients with severe radiation proctitis several sessions are usually necessary, and success is not certain; in these cases, topical formalin administration may be more effective. Endoscopic severity of haemorrhagic radiation proctitis may be useful to guide appropriate therapy.
