The implications of hormone treatment for cancer risk, screening and treatment in transgender individuals.

There is evidence that gender-affirming hormone treatment (GAHT) for transgender individuals modulates their risk for specific malignancies including breast and prostate cancer, and meningiomas. However, there is insufficient data to make precise risk estimates accounting for age and inherited cancer risk. As such, screening recommendations remain broad. Even less evidence exists for best practice in the management of active or historical cancers in the transgender population. Guidance is therefore mainly extrapolated from cisgender populations but with considerations of the significant benefits of GAHT in the face of any hormonal risk. Clinical experience, the multidisciplinary team and shared decision making with the patient are vital in providing person-centred care, while further research is acquired.

Anal metastasis in esophageal cancer: A case report.

BACKGROUND: Esophageal cancer is the sixth leading cause of cancer-related death and eighth most common cancer, affecting > 450000 people worldwide. Esophageal squamous cell carcinoma is the most common histological type, whereas esophageal adenoid cystic carcinoma (EACC) is rare. The liver is the most common distant metastatic site in esophageal cancer. Anal metastasis is rare and has not been reported in clinical practice before. Here, we report anal metastases in a patient with EACC after regular chemotherapy and surgical resection. CASE SUMMARY: A 61-year-old esophageal cancer patient was found to have lung and brain metastases during standardized treatment. The patient's treatment plan was continuously adjusted according to the latest treatment guidelines. However, the patient subsequently noticed rectal bleeding and itching, and after obtaining pathology results at the local hospital, anal metastasis of esophageal cancer was diagnosed. CONCLUSION: Postoperative pathology and immunohistochemistry confirmed EACC with rare anal metastasis. More exploration of EACC diagnosis and treatment is needed.

Future patterns in burden and incidence of squamous cell carcinoma of the anus in the United States, 2001-2035.

Squamous cell carcinoma of the anus (SCCA) incidence has been rising in the United States, particularly among older adults (≥65 years). We estimated the impact of this rise on future burden (through 2035) using age-period-cohort modeling. The SCCA burden (cases/year) is expected to rise, reaching ∼2700 among men and ∼7000 among women in 2031-2035 (burden during 2016-2020 among men and women was ∼2150 and ∼4600), with most cases aged ≥65 years (61% in men and 70% in women in 2031-2035; from 40% and 46% in 2016-2020). SCCA incidence (per 100,000) is projected to rise among older men aged 65-74, 75-84, and ≥85 years (5.0, 4.9, and 4.3, in 2031-2035 vs 3.7, 3.8, 3.4 in 2016-2020) and women (11.2, 12.6, 8.0 in 2031-2035 vs 8.2, 6.8, 5.2 in 2016-2020). The projected rise in SCCA burden among older adults is troubling and highlights the importance of improving early detection and clinical care.

Prognostic Value of 18F-FDG PET/CT Assessment After Radiotherapy of Squamous Cell Carcinoma of the Anus in Patients from the National Multicentric Cohort FFCD-ANABASE.

This study aimed to evaluate the prognostic value of 18F-FDG PET/CT qualitative assessment in terms of recurrence-free survival (RFS), colostomy-free survival (CFS), and overall survival (OS) after radiation therapy (RT) of squamous cell carcinoma of the anus (SCCA). Secondary objectives were to evaluate the prognostic value of baseline and posttherapeutic quantitative 18F-FDG PET/CT parameters in terms of RFS, CFS, and OS. Methods: We included all consecutive patients from the French multicentric cohort FFCD-ANABASE who had undergone 18F-FDG PET/CT at baseline and 4-6 mo after RT or chemoradiotherapy for a localized SCCA. Qualitative assessments separated patients with complete metabolic response (CMR) and non-CMR. Quantitative parameters were measured on baseline and posttreatment 18F-FDG PET/CT. RFS, CFS, and OS were analyzed using the Kaplan-Meier method. Associations among qualitative assessments, quantitative parameters, and RFS, CFS, and OS were analyzed using univariate and multivariate Cox regression. Results: Among 1,015 patients treated between January 2015 and April 2020, 388 patients (300 women and 88 men) from 36 centers had undergone 18F-FDG PET/CT at diagnosis and after treatment. The median age was 65 y (range, 32-90 y); 147 patients (37.9%) had an early-stage tumor and 241 patients (62.1%) had a locally advanced-stage tumor; 59 patients (15.2%) received RT, and 329 (84.8%) received chemoradiotherapy. The median follow-up was 35.5 mo (95% CI, 32.8-36.6 mo). Patients with CMR had better 3-y RFS, CFS, and OS, at 84.2% (95% CI, 77.8%-88.9%), 84.7% (95% CI, 77.2%-89.3%), and 88.6% (95% CI, 82.5%-92.7%), respectively, than did non-CMR patients, at 42.1% (95% CI, 33.4%-50.6%), 47.9% (95% CI, 38.1%-56.8%), and 63.5 (95% CI, 53.2%-72.1%), respectively (P < 0.0001). Quantitative parameters were available for 154 patients from 3 centers. The following parameters were statistically significantly associated with 3-y RFS: baseline SUVmax (primitive tumor [T]) (hazard ratio [HR], 1.05 [95% CI, 1.01-1.1; P = 0.018]), SUVpeak (T) (HR, 1.09 [95% CI, 1.02-1.15; P = 0.007]), MTV 41% (T) (HR, 1.02 [95% CI, 1-1.03; P = 0.023]), MTV 41% (lymph node [N]) (HR, 1.06 [95% CI, 1.03-1.1; P < 0.001]), MTV 41% (T + N) (HR, 1.02 [95% CI, 1-1.03; P = 0.005]), and posttreatment SUVmax (HR, 1.21 [95% CI, 1.09-1.34; P < 0.001]). Conclusion: Treatment response assessed by 18F-FDG PET/CT after RT for SCCA has a significant prognostic value.18F-FDG PET/CT could be useful for adapting follow-up, especially for patients with locally advanced-stage tumors. Quantitative parameters could permit identification of patients with a worse prognosis but should be evaluated in further trials.

Isolated bladder exstrophy with normal phallus and imperforated anus: "A case report".

This case report presents a rare occurrence of isolated bladder exstrophy with a normal phallus in a one-day-old male newborn. The patient also presented with imperforated anus, congenital heart disease, and a left ectopic kidney. Surgical interventions included cut-back anoplasty, bilateral ureteral reimplantation, and primary bladder closure in a single operation, resulting in a successful outcome without complications. Three months of follow-up showed satisfactory results.

Perianal Angioleiomyoma: A Case Report and Review of the Literature.

Angioleiomyomas are rare benign tumors, which take origin from smooth muscle fibers of the tunica media of veins. Even though angioleiomyomas can appear anywhere in the body, these masses are rarely occurred in the gastrointestinal system. This is the first reported case of perianal angioleiomyomas, where the tumor in close relation with the anal canal was investigated with endoanal ultrasonography. Local excision of such lesion is generally curative.

A Neonatal Case of Lower Urinary Tract Obstruction and Imperforate Anus: Urethral Decompression Due to Rectourinary Fistula.

Lower urinary tract obstruction (LUTO) is a rare fetal condition associated with significant perinatal morbidity and mortality. Herein, we report a neonatal case of LUTO with anal atresia complicated by anhydramnios and pulmonary hypoplasia. After treatment for severe postnatal respiratory distress, the neonate underwent vesicostomy and colostomy. Postoperatively, respiratory status and renal function improved. This case highlights a unique feature where a large rectovesical fistula channeled fetal urine into the colon, which minimized obstructive damage to the urinary tract and preserved renal morphology. Fetal colonic dilatation and numerous enteroliths indicate urine influx into the intestinal tract. Our case suggests the importance of recognizing such exceptions in complete LUTO to predict postnatal outcomes diagnosed in utero.

[Syphilis in surgery-Safe diagnosis and correct treatment]. / Syphilis in der Chirurgie ­ sicher erkennen, richtig behandeln.

BACKGROUND: The incidence of syphilis has clearly increased in Germany in recent years. This infectious disease has many forms of manifestation and can imitate surgical diseases. MATERIAL AND METHODS: Comprehensive footage of experiences in a proctological center demonstrates these manifestations and explains the correct management. RESULTS: The likelihood of confusion of syphilis with anal fissures, anogenital warts, proctitis and rectal cancer is high. CONCLUSION: Surgeons can encounter syphilis, the "chameleon of medicine" and must know the differential diagnoses.

A brief physiology and pathophysiology of the anorectum based on the Integral Theory paradigm.

The remit of this review is confined to the experimental scientific works and surgeries based on the Integral Theory paradigm. The video abstract summarizes the anorectal function, how ligaments cause dysfunction and cure of fecal incontinence and obstructed defecation by ligament repair. Anorectal function is reflex and binary, with cortical and peripheral components. The same three oppositely acting reflex muscle forces which open and close the bladder, contract against the pubourethral (PUL) and uterosacral (USL) ligaments: (I) to close the anorectum for continence when the puborectalis muscle (PRM) contracts forwards; (II) to open the anorectum prior to evacuation when the PRM relaxes; (III) to stretch the rectum in opposite directions to support the anorectal stretch receptors "N" to prevent premature activation of the defecation reflex, (fecal urgency). Weak or loose PULs or USLs may cause dysfunction of closure, of evacuation, and inability to control the defecation reflex (fecal urgency). Repair of the PUL and USL can improve or cure these dysfunctions. The perineal body (PB) acts as an anatomical support for the distal vagina, anorectum and external anal sphincter (EAS). It serves as an anchoring point for the forward action of the pubococcygeus muscle (PCM), which tensions the anterior rectal wall during closure and defecation. Bladder and bowel dysfunction have a similar pathogenesis, ligament laxity, mainly pubourethral and uterosacral, with added PB damage for anorectal dysfunction. PB damage can cause obstructive defecation and descending perineal syndrome (DPS). Repair of damaged PUL and USL can restore the closure and evacuation functions of both bladder an anorectum. DPS can be cured by repair of the PB's suspensory ligaments, deep transversus perinei.

Expanding the clinical spectrum of Coffin-Siris syndrome with anorectal malformations: Case report and review of the literature.

Anorectal malformations (ARMs) represent a wide spectrum of congenital anomalies of the anus and rectum, of which more than half are syndromic. Their etiology is highly heterogeneous and still poorly understood. We report a 4-year-old girl who initially presented with an isolated ARM, and subsequently developed a global developmental delay as part of an ARID1B-related Coffin-Siris syndrome (CSS). A co-occurrence of ARMs and CSS in an individual by chance is unexpected since both diseases are very rare. A review of the literature enabled us to identify 10 other individuals with both CSS and ARMs. Among the ten individuals reported in this study, 8 had a variant in ARID1A, 2 in ARID1B, and 1 in SMARCA4. This more frequent than expected association between CSS and ARM indicates that some ARMs are most likely part of the CSS spectrum, especially for ARID1A-related CSS.

Anorectal Malignant Melanoma Post- Hemorrhoidectomy.

Anorectal malignant melanoma, a rare and aggressive tumor, lacks specific symptoms and frequently presents diagnostic challenges due to its similarity to benign anorectal conditions. This case report describes the diagnostic and treatment process of incidentally discovered anorectal malignant melanoma post-hemorrhoidectomy, guided by the existing literature.

Hospitalization burden associated with anus and penis neoplasm in Spain (2016-2020).

In 2020, there were approximately 50,865 anal cancer cases and 36,068 penile cancer cases worldwide. HPV is considered the main causal agent for the development of anal cancer and one of the causal agents responsible for the development of penile cancer. The aim of this epidemiological, descriptive, retrospective study was to describe the burden of hospitalization associated with anal neoplasms in men and women and with penis neoplasms in men in Spain from 2016 to 2020. The National Hospital Data Surveillance System of the Ministry of Health, Conjunto Mínimo Básico de Datos, provided the discharge information used in this observational retrospective analysis. A total of 3,542 hospitalizations due to anal cancer and 4,270 hospitalizations due to penile cancer were found; For anal cancer, 57.4% of the hospitalizations occurred in men, and these hospitalizations were also associated with significantly younger mean age, longer hospital stays and greater costs than those in women. HIV was diagnosed in 11.19% of the patients with anal cancer and 1.74% of the patients with penile cancer. The hospitalization rate was 2.07 for men and 1.45 for women per 100,000 in anal cancer and of 4.38 per 100,000 men in penile cancer. The mortality rate was 0.21 for men and 0.12 for women per 100,000 in anal cancer and 0.31 per 100.000 men in penile cancer and the case-fatality rate was 10.07% in men and 8,26% in women for anal cancer and 7.04% in penile cancer. HIV diagnosis significantly increased the cost of hospitalization. For all the studied diagnoses, the median length of hospital stays and hospitalization cost increased with age. Our study offers relevant data on the burden of hospitalization for anal and penile cancer in Spain. This information can be useful for future assessment on the impact of preventive measures, such as screening or vaccination in Spain.

Prognostic Significance of Bulky Nodal Disease in Anal Cancer Management: A Multi Institutional Study.

Purpose: This study aimed to assess the prognostic significance of bulky nodal involvement in patients with anal squamous cell carcinoma treated with definitive chemoradiotherapy. Materials and Methods: We retrospectively analyzed medical records of patients diagnosed with anal squamous cell carcinoma who underwent definitive chemoradiotherapy at three medical centers between 2004 and 2021. Exclusion criteria included distant metastasis at diagnosis, 2D radiotherapy, and salvage treatment for local relapse. Bulky N+ was defined as nodes with a long diameter of 2 cm or greater. Results: A total of 104 patients were included, comprising 51 with N0, 46 with non-bulky N+, and 7 with bulky N+. The median follow-up duration was 54.0 months (range, 6.4-162.2 months). Estimated 5-year progression-free survival (PFS), loco-regional recurrence-free survival (LRRFS), and overall survival (OS) rates for patients with bulky N+ were 42.9%, 42.9%, and 47.6%, respectively. Bulky N+ was significantly associated with inferior PFS, LRRFS and OS compared to patients without or with non-bulky N+, even after multivariate analysis. We proposed a new staging system incorporating bulky N+ as N2 stage, with estimated 5-year LRRFS, PFS, and OS rates of 81.1%, 80.6%, and 86.2% for stage I, 67.7%, 60.9%, and 93.3% for stage II, and 42.9%, 42.9%, and 47.6% for stage III disease, enhancing the predictability of prognosis. Conclusion: Patients with bulky nodal disease treated with standard chemoradiotherapy experienced poor survival outcomes, indicating the potential necessity for further treatment intensification.

Development of a Standardized Algorithm for Management of Newly Diagnosed Anorectal Malformations.

Neonates with a new diagnosis of anorectal malformation (ARM) present a unique challenge to the clinical team. ARM is strongly associated with additional midline malformations, such as those observed in the VACTERL sequence, including vertebral, cardiac, and renal malformations. Timely assessment is necessary to identify anomalies requiring intervention and to prevent undue stress and delayed treatment. We utilized a multidisciplinary team to develop an algorithm guiding the midline workup of patients newly diagnosed with ARM. Patients were included if born in or transferred to our neonatal intensive care unit (NICU), or if seen in clinic within one month of life. Complete imaging was defined as an echocardiogram, renal ultrasound, and spinal magnetic resonance imaging or ultrasound within the first month of life. We compared three periods: prior to implementation (2010-2014), adoption period (2015), and delayed implementation (2022); p ≤ 0.05 was considered significant. Rates of complete imaging significantly improved from pre-implementation to delayed implementation (65.2% vs. 50.0% vs. 97.0%, p = 0.0003); the most growth was observed in spinal imaging (71.0% vs. 90.0% vs. 100.0%, p = 0.001). While there were no differences in the rates of identified anomalies, there were fewer missed diagnoses with the algorithm (10.0% vs. 47.6%, p = 0.05). We demonstrate that the implementation of a standardized algorithm can significantly increase appropriate screening for anomalies associated with a new diagnosis of ARM and can decrease delayed diagnosis. Further qualitative studies will help to refine and optimize the algorithm moving forward.

Long-term outcome of stem cell transplantation with and without anti-tumor necrotic factor therapy in perianal fistula with Crohn's disease.

BACKGROUND: Stem cell transplantation is a promising therapeutic option for curing perianal fistula in Crohn's disease (CD). Anti-tumor necrotic factor (TNF) therapy combined with drainage procedure is effective as well. However, previous studies are limited to proving whether the combination treatment of biologics and stem cell transplantation improves the effect of fistula closure. AIM: This study aimed to evaluate the long-term outcomes of stem cell transplantation and compare Crohn's perianal fistula (CPF) closure rates after stem cell transplantation with and without anti-TNF therapy, and to identify the factors affecting CPF closure and recurrence. METHODS: The patients with CD who underwent stem cell transplantation for treating perianal fistula in our institution between Jun 2014 and December 2022 were enrolled. Clinical data were compared according to anti-TNF therapy and CPF closure. RESULTS: A total of 65 patients were included. The median age of females was 26 years (range: 21-31) and that of males was 29 (44.6%). The mean follow-up duration was 65.88 ± 32.65 months, and complete closure was observed in 50 (76.9%) patients. The closure rates were similar after stem cell transplantation with and without anti-TNF therapy (66.7% vs 81.6% at 3 year, P = 0.098). The patients with fistula closure had short fistulous tract and infrequent proctitis and anorectal stricture (P = 0.027, 0.002, and 0.008, respectively). Clinical factors such as complexity, number of fistulas, presence of concurrent abscess, and medication were not significant for closure. The cumulative 1-, 2-, and 3-year closure rates were 66.2%, 73.8%, and 75.4%, respectively. CONCLUSION: Anti-TNF therapy does not increase CPF closure rates in patients with stem cell transplantation. However, both refractory and non-refractory CPF have similar closure rates after additional anti-TNF therapy. Fistulous tract length, proctitis, and anal stricture are risk factors for non-closure in patients with CPF after stem cell transplantation.

OIES complex diagnosed by in utero ultrasound a case report.

INTRODUCTION AND IMPORTANCE: OEIS complex is a rare and complex anomaly of the genitourinary and intestinal tract. It includes Omphalocele, Exstrophy of cloaca, Imperforate anus and Spinal defects. PRESENTATION OF CASE: We are reporting a case of OEIS complex. CLINICAL DISCUSSION: Cloacal exstrophy is considered the most severe ventral abdominal wall defect. Diagnosis is primarily antenatal based on the presenting features on ultrasonography. Management requires initial resuscitation and stabilization followed by either single staged closure or multistage procedures by multi-disciplinary surgical team. CONCLUSION: The introduction of better diagnostic techniques and the detection of fetal malformations during pregnancy is it's the cornerstone of care.

Transanal fistula repair for the treatment of rectovestibular fistula with normal anus in female children: a 5-year single-center experience.

PURPOSE: The purpose of this study was to review a 5-year operative experience of transanal fistula repair for the treatment of rectovestibular fistula with a normal anus in female children. METHODS: In this study, we conducted a retrospective review of children diagnosed with rectovestibular fistula with normal anus who underwent transanal fistula repair in the department of General Surgery, Children's Hospital of Chongqing Medical University. Clinical data were retrospectively analyzed. RESULTS: A total of 56 female children were included in the study. The patients' ages ranged from 1 year 10 months to 15 years 11 months, with an average age of 5 years 1 month. These children had a clear history of gas or loose stool leakage through the vestibular area, with or without a history of vestibular infection. All patients had a normal anus and underwent transanal fistula repair. Follow-up was conducted through telephone or outpatient visits for a duration of 10 months to 5 years (average follow-up duration 19 months). Three patients experienced minimal secretion from the external orifice of the vestibular fistula within two weeks after the operation, but were successfully treated with sitting bath therapy without any relapse. Another three cases had a recurrence of the fistula, and two of them underwent transanal fistula repair at our center again, resulting in a successful cure after reoperation. The remaining case has not yet undergone reoperation. In the long-term follow-up, all the children had satisfactory anal appearance, with no fecal incontinence, anorectal stenosis, or fistula infection. CONCLUSION: Transanal fistula repair is a simple, safe, and effective surgical method to treat female children with rectovestibular fistula with a normal anus.

Incidence and clearance of cervical and anal high-risk human papillomavirus in kidney transplant recipients: Results from a Danish prospective clinical study.

This study investigates the incidence and clearance of cervical and anal high-risk human papillomavirus (hrHPV) infection in kidney transplant recipients (KTRs) compared to immunocompetent controls. During 2016-2017, we enrolled 125 female KTRs and 125 female controls. Liquid-based cervical and anal cytology samples collected at enrollment and follow-up were tested for human papillomavirus (HPV) DNA using the CLART HPV2 test. All participants answered a questionnaire on lifestyle and sexual behavior at both examinations. KTRs had an increased age-adjusted risk of incident cervical hrHPV infection compared to controls (hazard ratio [HR] = 3.6, 95% CI = 1.2-11.2). Probability of cervical hrHPV clearance at 18 months was lower among KTRs (8.3%) than controls (66.7%). There was no statistically significant difference in anal hrHPV incidence between KTRs and controls (HR = 0.9, 95% CI = 0.4-2.0). Clearance of anal hrHPV was similar between KTRs and controls at 18 months. During the total follow-up, a lower anal hrHPV clearance, although not statistically significant, was observed among KTRs (HR = 0.3, 95% CI = 0.06-1.2). KTRs had higher incidence of cervical hrHPV and lower probability of clearance, especially of cervical hrHPV infections, than controls. Our findings support that KTRs are at increased risk of HPV infection and point to the need for targeted HPV prevention strategies, such as cervical cancer screening.

Squamous cell carcinoma of the anus successfully treated with multidisciplinary therapy for metachronous metastatic and local recurrences after DCF chemotherapy: a case report.

BACKGROUND: Docetaxel, cisplatin, and 5-fluorouracil (DCF) chemotherapy is reportedly an effective treatment strategy for squamous cell carcinoma of the anus (SCCA). However, studies regarding its use in Japanese patients remain scarce. CASE PRESENTATION: Here, we present the case of an 82-year-old woman with SCCA, cStage IIIB. Chemoradiotherapy was initiated after colostomy of the anorectal mass; however, para-aortic lymph node recurrence was observed 3 months after treatment completion. Five courses of DCF chemotherapy were subsequently administered, resulting in a complete response (CR). Two years and 1 month later, the aortic lymph node was enlarged again, and the patient achieved CR again after radiotherapy. Nine months later, local recurrence was detected in the anal canal, and laparoscopic perineal rectal amputation was performed. The patient remains progression-free 5 years and 10 months after the initial treatment and 1 year and 7 months after the final treatment. CONCLUSIONS: Our findings suggest that complementary treatment after DCF chemotherapy may be efficacious in Japanese patients with SCCA and help achieve CR. Despite occasional local recurrences, this approach may help achieve long-term progression-free survival.
