PURPOSES: Healing after abdomino-perineal resection is often difficult, especially in patients who have undergone radiation therapy. Vaginal reconstruction is also an important issue for the women who undergo this surgery. We describe and analyze here our series of perineal reconstructions with modified Taylor flaps. Between 2010 and 2016, 68 patients (52 women, 16 men) with cancer of the anal canal (53), adenocarcinoma of the lower rectum (9), or other malignant neoplasms of the perineum underwent reconstruction with a rectus abdominis myocutaneous (RAM) flap with an inferior pedicle and an oblique skin paddle...

Although a rare disease, anal cancer is increasingly being diagnosed in patients with risk factors, mainly anal infection with the human papilloma virus. Magnetic resonance imaging (MRI) with external phased-array coils is recommended as the imaging modality of choice to grade anal cancers and to evaluate the response assessment after chemoradiotherapy, with a high contrast and good anatomic resolution of the anal canal. MRI provides a performant evaluation of size, extent and signal characteristics of the anal tumor before and after treatment, as well as lymph node involvement and extension to the adjacent organs...

Human papillomavirus (HPV) infection is the pathogenesis of anogenital cancers and genital warts in both men and women, whereas there is a scarcity of large studies focused on HPV prevalence in different anogenital sites of both sexes in the same population. From May to July 2014, 2309 men and 2378 women aged 18-55 were enrolled from a community in Liuzhou, China. Penis/glans penis/coronary sulcus (PGC) and perianal/anal canal (PA) specimens of men, and vaginal (VA), vulvar (VU) and PA specimens of women, were collected and genotyped for HPV...

Importance: The incidence of squamous cell carcinoma of the anal canal (SCCAC) is increasing. Although standard management of SCCAC includes the use of concurrent chemotherapy and radiotherapy (chemoradiotherapy), data are lacking on potentially less morbid, alternative management strategies, such as local excision, among patients with node-negative T1 disease. Objectives: To examine the use of local excision among patients with T1 SCCAC and to compare overall survival relative to those who received standard treatment with chemoradiotherapy...

Posterior reversible encephalopathy syndrome (PRES), first introduced in 1996, is a neurotoxic state characterised by seizures, headache, vision change, paresis, nausea and altered mental status. Risk factors include hypertension, eclampsia/pre-eclampsia, infection/sepsis and cancer chemotherapy. Although exposure to toxic agents is a common occurrence in patients who develop PRES, oxaliplatin has rarely been associated with it, with only 10 cases reported worldwide. We present the case of an oxaliplatin-induced PRES in a 23-year-old male patient who was started on oxaliplatin/capecitabine as adjuvant chemotherapy for anal canal adenocarcinoma...

Leiomyosarcoma accounts for only a small percentage of colorectal malignancies and remains a difficult disease to diagnose and treat. Here, we describe a case of leiomyosarcoma in a middle-age female first identified on colonoscopy. The cancer had invaded the posterior vaginal wall necessitating an abdominoperineal resection with partial vaginectomy and pelvic floor reconstruction with neovagina creation. Final pathologic analysis revealed invasion into the posterior vaginal wall without direct involvement of the vaginal squamous mucosa...

BACKGROUND: The incidence of squamous cell carcinoma (SCC) of the anal canal has been rising over the past decades, especially in patients infected with human immunodeficiency virus (HIV). Despite the advent of potent multidrug regimens to treat HIV-termed highly active antiretroviral therapy (HAART), anal SCC rates have not declined, and the impact of HAART on anal SCC remains controversial. AIM: The purpose of this study was to define outcomes of anal SCC treatment in HIV-positive and HIV-negative patients...

Bladder dose constraints in case of conformational radiotherapy/intensity-modulated radiotherapy and stereotactic radiotherapy are reported from the literature, in particular from the French radiotherapy society RECORAD recommendations, according to the treated pelvic tumor sites. The dose-volume effect on urinary toxicity is not clearly demonstrated, making difficult to establish absolute dose constraints for the bladder. In case of high-dose prostate cancer radiotherapy, the bladder dose constraints are: V60Gy<50% and maximum dose<80Gy for standard fractionation and V60Gy<5%, V48Gy<25% and V41Gy<50% for moderate hypofractionation (20 fractions of 3Gy)...

OBJECTIVE: Anal cancer is a common cancer among men who have sex with men (MSM); however, there is no standard screening protocol for anal cancer. We conducted a phase II clinical trial to assess the feasibility of teaching MSM to recognise palpable masses in the anal canal which is a common sign of anal cancer in men. METHODS: A clinician skilled in performing digital anorectal examinations (DARE) used a pelvic manikin to train 200 MSM, aged 27-78 years, how to do a self-anal examination (SAE) for singles or a partner anal examination (PAE) for couples...

We report a case of perianal squamous cell carcinoma and left inguinal lymph node metastasis that showed a complete response more than 5 years after chemotherapy and concomitant proton beam therapy. A 34-year-old woman was referred to our hospital for an anal tumor and a left inguinal tumor. A digital rectal examination revealed a tumor in the anterior wall of the anal canal. In addition, the left inguinal lymph nodes were swollen, leading us to suspect metastases. Biopsy specimens confirmed poorly differentiated squamous cell carcinoma...
