[PMID: 40200602 DOI: 10.1111/codi.70086] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2024] [Revised: 01/28/2025] [Accepted: 03/05/2025] [Indexed: 04/10/2025]
Abstract
AIM Chronic radiation proctopathy (CRP) is a significant side-effect of radiotherapy, and poses a challenge in clinical management, necessitating effective and standardized therapeutic approaches. The aim of this review is to investigate the role of endoscopic interventions for CRP, focusing on argon plasma coagulation (APC) and formalin application. METHOD A literature search was undertaken for studies that investigated the clinical responses to endoscopic management in patients with CRP. A systematic review was performed in accordance with PRISMA guidelines, and a meta-analysis of proportions was conducted with a random-effects model. ROBINS-I and the Cochrane Collaboration's tool were used to assess risk of bias in cohort studies and randomized control trials, respectively. RESULTS A total of 82 studies met the inclusion criteria, including 11 randomized control trials, 20 systematic reviews, one cohort study and 50 case series. A robust 89% (95% CI 84%-92%, p < 0.01 and 95% CI 84%-93%, p = 0.03) pooled response rate was demonstrated for both APC and formalin therapies, respectively. Adverse effects were generally minimal. CONCLUSION Endoscopic therapies, particularly APC and formalin, exhibit commendable clinical response rates in the management of CRP. However, the lack of standardized treatment protocols highlights the need for larger prospective studies. Clear guidelines, informed by defined outcomes and quality-of-life assessments, are imperative for enhancing patient outcomes and minimizing the morbidity associated with CRP.

Abstract
BACKGROUND argon plasma coagulation (APC) is the current endoscopic treatment of choice for patients who develop chronic radiation proctopathy. The aim of this study was to identify risk factors associated with treatment failure. METHODS one hundred and ninety-nine patients treated with argon plasma coagulation in a single center were retrospectively analyzed. RESULTS twenty-four (12.06 %) patients were classified as APC treatment failures. Requirement of red blood cells transfusion and/or hemoglobin < 7 g/dl (OR 12.19, 95 % CI: 2.78-53.45, p < 0.001) and severe bleeding frequency (OR 2.76, 95 % CI: 1.13-6.72, p = 0.03) at diagnosis and prior to endoscopic therapy were associated with argon plasma coagulation treatment failure. Nineteen patients of the successful therapy group developed bleeding recurrence; no risk factors were associated with a shorter recurrence-free time. More than four APC sessions were associated to a higher risk of surgical intervention for bleeding control (OR 87.00, 95 % CI: 10.23-740.18, p < 0.001). CONCLUSION requirement of red blood cells transfusion and/or hemoglobin < 7 g/dl and a severe bleeding frequency (more than five days per week) were identified as the most important risk factors for treatment failure in patients with chronic radiation proctopathy.

Cancers (Basel) 2023; 15:cancers15082386. [PMID: 37190314 DOI: 10.3390/cancers15082386] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/07/2023] [Accepted: 04/18/2023] [Indexed: 05/17/2023] Open
Abstract
Medical use of (non-)thermal plasmas is an emerging field in gynaecology. However, data on plasma energy dispersion remain limited. This systematic review presents an overview of plasma devices, fields of effective application, and impact of use factors and device settings on tissues in the female pelvis, including the uterus, ovaries, cervix, vagina, vulva, colon, omentum, mesenterium, and peritoneum. A search of the literature was performed on 4 January 2023 in the Medline Ovid, Embase, Cochrane, Web of Science, and Google Scholar databases. Devices were classified as plasma-assisted electrosurgery (ES) using electrothermal energy, neutral argon plasma (NAP) using kinetic particle energy, or cold atmospheric plasma (CAP) using non-thermal biochemical reactions. In total, 8958 articles were identified, of which 310 were scanned, and 14 were included due to containing quantitative data on depths or volumes of tissues reached. Plasma-assisted ES devices produce a thermal effects depth of <2.4 mm. In turn, NAP effects remained superficial, <1.0 mm. So far, the depth and uniformity of CAP effects are insufficiently understood. These data are crucial to achieve complete treatment, reduce recurrence, and limit damage to healthy tissues (e.g., prevent perforations or preserve parenchyma). Upcoming and potentially high-gain applications are discussed, and deficits in current evidence are identified.

Abstract
Introduction Chronic radiation proctitis is a common chronic complication of malignant pelvic diseases after pelvic radiation therapy. Although, the incidence has decreased after advent of intensity-modulated radiotherapy due to better control of radiation dose to rectum. In the era of conventional two-field radiotherapy to pelvis, this was a common complication usually presenting after 1-2 years of treatment completion. Rectal bleeding caused by radiation proctitis is difficult to manage. Argon plasma coagulation (APC) is an electrocoagulation technique that appears to be an effective and low-cost alternative to the use of lasers in gastrointestinal endoscopy. The aim of this study was to evaluate the efficacy of APC, as well as patients' tolerance of the procedure, in the treatment of bleeding radiation-induced proctitis. Materials and Methods Between January 2015 and August 2017, 29 patients of cancer cervix treated with definite radiotherapy both external and brachytherapy who suffered from rectal bleeding due to radiation proctitis were included for treatment with argon plasma laser (APC). Twenty-three patients suffered from anemia, 16 of whom required blood transfusion. APC was performed, applying the no-touch spotting technique at an electrical power of 40 Watt and an argon gas flow of 1.5-2.0 l/min. Pulse duration was <0.5 s. Treatment sessions were carried out at intervals of 3 weeks. Subjects received 2-4 treatment sessions. Results Twenty-eight out of 29 patients were accessible for effects and results. APC led to persistent clinical and endoscopic remission of rectal bleeding after a median of three sessions. No adverse effects were encountered after initial treatment. All the patients were in complete remission. Conclusions APC is an effective, safe, and well-tolerated treatment for rectal bleeding caused by chronic radiation proctitis. It should be considered as a first-line therapy for radiation proctitis.

Abstract
Anemia was a risk factor for a worse prognosis of many diseases. This study aims to investigate the relationship between anemia and the severity and prognosis of acute pancreatitis (AP). Inpatients hospitalized at the First Affiliated Hospital of Guangdong Pharmaceutical University with a primary diagnosis of AP between 1st July 2016 to 31st December 2020 were enrolled. Subsequently, disease severity, the incidence of complications, and the prognosis of patients with AP were compared between the anemic group and the non-anemic group. A total of 282 patients with acute pancreatitis were enrolled; 68.43% of them were also diagnosed with anemia. Notably, these patients had more severe disease (higher RANSON, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, and multiple organ dysfunction syndrome scores); higher incidence of organ failure (acute kidney injury [AKI] and acute heart failure); worse prognosis (higher incidence of vasoactive and diuretic agent use, longer hospital stays, and higher hospital costs) compared to that of patients without anemia (all P < .05). After adjusting for potential confounders, acute physiologic assessment and chronic health evaluation-II, bedside index for severity in acute pancreatitis, multiple organ dysfunction syndrome scores, hospital stay, and hospital costs in anemic patients were higher than those in non-anemic patients; besides, the incidence of AKI and using a diuretic agent in anemic patients was 6.645 and 4.053 times that of non-anemic patients in AP, respectively (all P < .05). Acute pancreatitis patients with anemia have more disease severity, higher incidence of AKI, and worse prognosis compared to those without anemia.

Abstract
AbstractMalignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this pathology. Despite the prevalence of radiation-induced proctopathy, there is no definitive standardized treatment strategy so far. The first approach can be tried with local agents, such as mesalazine and formalin. For refractory cases, control can usually be achieved with argon plasma coagulation, hyperbaric oxygen, and radiofrequency ablation therapies. Regarding the study of radiation-induced proctopathy, there is a lack of robust studies with large samples and standardized therapies to be compared. There is a lack of double-blinded, randomized controlled studies to determine a definitive standard treatment algorithm.

Risk Prediction and Treatment of LE-DVT in Patients with Chronic Radiation Intestinal Injury: A Retrospective Case-Control Study. Cancer Manag Res 2021; 13:6611-6619. [PMID: 34466031 PMCID: PMC8397618 DOI: 10.2147/cmar.s319918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Accepted: 07/26/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Chronic radiation intestinal injury (CRII) is the most common complication after pelvic malignancy radiation. Once hemorrhagic CRII patients suffer from lower extremity deep venous thrombosis (LE-DVT), hemostasis and anticoagulation therapy will be adopted simultaneously, but the treatment strategy is a paradox, as the condition is extremely intractable and serious. The aim of this study was to investigate the prevalence of and risk factors for LE-DVT in CRII patients and explore the treatment of hemorrhagic CRII patients with LE-DVT. METHODS This was a retrospective study, and a total of 608 hospitalized CRII patients after pelvic radiotherapy were included from November 2011 to October 2018. Univariate and multivariate analyses were conducted to investigate the potential risk factors for LE-DVT in CRII patients. Furthermore, the treatment of hemorrhagic CRII patients with LE-DVT was explored. RESULTS Among the CRII patients, 94 (15.5%) were with suspicious symptoms of LE-DVT in the lower limbs, and 32 (5.3%) were diagnosed with LE-DVT. Among the patients with LE-DVT, 65.6% (21/32) had bleeding simultaneously, and 29 (90.6%) had anemia with 24 (75.0%) having moderate to severe anemia. Multivariate analysis showed that a recent surgical history (≤6 months) (OR = 5.761, 95% CI: 2.506~13.246, p < 0.001), tumor recurrence or metastasis (OR = 3.049, 95% CI: 1.398~6.648, p = 0.005) and the hemoglobin (Hb) level (OR = 0.960, 95% CI: 0.942~0.979, p < 0.001) were significantly associated with the development of LE-DVT. ROC curve analysis showed that the AUC of the merged risk score of the independent risk factors was 0.822 (95% CI: 0.789~0.852), and the optimal Hb cutoff was 82.5 g/L. After colostomy, obvious bleeding remission was rapidly found in 84.6% of hemorrhagic CRII patients with LE-DVT. CONCLUSION The prevalence of LE-DVT in hospitalized CRII patients was 5.3%. A recent surgical history, tumor recurrence or metastasis and a lower Hb level were independently associated with LE-DVT development in CRII patients. Colostomy could be a good choice for intractable hemorrhagic CRII patients with LE-DVT.

Abstract
OBJECTIVES We sought to determine the added value of diffusion-weighted magnetic resonance imaging (DWI) in the differentiation of pelvic insufficiency fracture (PIF) from bone metastasis after radiotherapy in cervical cancer patients. METHODS In the present study, 42 cervical cancer patients after radiotherapy with 61 bone lesions (n = 40, PIFs; n = 21, bone metastasis) were included. Conventional MRI and DWI were performed in all patients. For qualitative imaging diagnosis, two sets of images were reviewed independently by three observers, including a conventional MRI set (unenhanced T1-weighted, T2-weighted, and enhanced T1-weighted images) and a DWI set (conventional MRIs, DW images, and ADC maps). The mean ADC value of each lesson was measured on ADC maps. The diagnostic performance was assessed by using the area under the receiver operating characteristic curve (Az), and sensitivity and specificity were determined. RESULTS For all observers, the Az value and sensitivity of the DWI set showed improvement compared with the conventional MRI set. The observer who had the least experience (3 years) demonstrated significant improvement in diagnostic performance with the addition of DWI; Az value increased from 0.804 to 0.915 (p = 0.042) and sensitivity increased from 75.0 to 92.5% (p = 0.035). The mean ADCs of the PIFs were significantly higher than the bone metastases (p < 0.001); ADC values > 0.97 × 10-3 mm2/s yielded an Az of 0.887, a sensitivity of 92.5%, and a specificity of 76.2%. CONCLUSIONS The addition of DWI to conventional MRI improved the differentiation of PIF from bone metastasis after RT in patients with cervical cancer. KEY POINTS • DWI showed additive value to conventional MRI in the differentiation of PIF from bone metastasis after RT. • For qualitative diagnosis, the addition of DWI can improve diagnostic performance compared with conventional MRI alone and can particularly improve the sensitivity. • Quantitative ADC assessment showed potential value for identifying PIF from bone metastasis.

Abstract
BACKGROUND Chronic radiation proctitis (CRP) is a complication which occurs in 1%-5% of patients who undergo radiotherapy for pelvic malignancies. Although a wide range of therapeutic modalities are available, there is no literature to date showing any particularly appropriate therapeutic modality for each disease stage. Argon plasma coagulation (APC) is currently recommended as the first-choice treatment for hemorrhagic CRP, however, its indication based on long-term follow-up is still unclear. On the hypothesis that the long-term efficacy and safety of APC are not fully understood, we reviewed APC treatment for patients with hemorrhagic CRP from a single center. AIM To assess the long-term efficacy and safety of APC for hemorrhagic CRP. METHODS This is a retrospective study of consecutive patients treated with APC for hemorrhagic CRP from January 2013 to October 2017. Demographics, clinical variables, and typical endoscopic features were recorded independently. Success was defined as either cessation of bleeding or only occasional traces of bloody stools with no further treatments for at least 12 mo after the last APC treatment. We performed univariate and multivariate analyses to identify factors associated with success and risk factors for fistulas. RESULTS Forty-five patients with a median follow-up period of 24 mo (range: 12-67 mo) were enrolled. Fifteen (33.3%) patients required blood transfusion before APC. Successful treatment with APC was achieved in 31 (68.9%) patients. The mean number of APC sessions was 1.3 (1-3). Multivariate analysis showed that APC failure was independently associated with telangiectasias present on more than 50% of the surface area [odds ratio (OR) = 6.53, 95% confidence interval (CI): 1.09-39.19, P = 0.04] and ulcerated area greater than 1 cm2 (OR = 8.15, 95%CI: 1.63-40.88, P = 0.01). Six (13.3%) patients had severe complications involving rectal fistulation. The only factor significantly associated with severe complications was ulcerated area greater than 1 cm2 (P = 0.035). CONCLUSION The long-term efficacy of APC for hemorrhagic CRP is uncertain in patients with telangiectasias present on > 50% of the surface area and ulceration > 1 cm2.
