Presentation
We present a patient with HCS who developed anal squamous cell carcinoma. [ncbi.nlm.nih.gov]
Patients may present with a hard, mobile or fixed mass on digital examination. Symptoms of an anal canal cancer may have been present for months to years before a correct diagnosis is suspected. [lacolon.com]
Gastrointestinal
- Rectal Bleeding
Can be caused by high risk HPV ( Cancer Res 1999;59:753 ) EGFR overexpression is common ( Mod Pathol 2006;19:942 ) Clinical features Presenting symptoms include rectal bleeding, pain, mass Treatment Surgery with chemoradiation Clinical images Images hosted [pathologyoutlines.com]
The most common symptom is rectal bleeding or blood in the stools (poo), with almost half of all patients affected in this way. [beatingbowelcancer.org]
Affecting approximately 7,000 people in the United States each year, anal cancer can cause rectal bleeding and anal pain. Anal cancer is divided into cancers of the anal canal and cancers of the lower part of the anus known as the anal margin. [brighamandwomens.org]
Anal cancer often presents with rectal bleeding. People who experience bleeding, itching, or pain in the anus often go to the doctor before anal cancer progresses past stage one. [healthline.com]
Symptoms and signs Common symptoms of anal cancer may include rectal bleeding noticeable if there is blood on feces or toilet paper pain in the anal area lumps around the anus, which may be mistaken for piles, or hemorrhoids mucus or jelly-like discharge [medicalnewstoday.com]
- Constipation
WHAT IS CONSTIPATION Constipation is a common complaint and usually simple to prevent and easy to treat when it occurs. [fascrs.org]
By the end of October 2009, Tiffany was experiencing extreme fatigue, severe constipation, and progressively worsening rectal pain and pressure. [oncnursingnews.com]
In case 2, a 71-year-old woman underwent a colonoscopy due to constipation, and an elevated lesion, 25 mm in size, was identified from the dentate line to the anal canal. [karger.com]
Side effects may include: diarrhea or constipation soreness and blistering around the target area, which is the anus a higher susceptibility to infections during treatment fatigue loss of appetite nausea or vomiting mouth ulcers or sore mouth loss of [medicalnewstoday.com]
Other symptoms include: Small lumps seen or felt around the anus which could be confused with piles An increase in the number or size of piles Pain in the anal area – affects about 30% of people Difficulty in passing stools and extreme constipation are [beatingbowelcancer.org]
- Fecal Incontinence
WHAT IS FECAL INCONTINENCE? Fecal incontinence (also called anal or bowel incontinence) is the impaired ability to control the passage of gas or stool. This is a common problem, but often not discussed due to embarrassment. [fascrs.org]
Some patients have fecal incontinence after combined chemotherapy and radiation. Biopsies to document disease regression after chemotherapy and radiation were commonly advised, but are not as frequent any longer. [en.wikipedia.org]

- Rectal Pain
By the end of October 2009, Tiffany was experiencing extreme fatigue, severe constipation, and progressively worsening rectal pain and pressure. [oncnursingnews.com]
Within one month of his surgery, the patient developed severe rectal pain and bleeding. Physical exam was limited at this time due to patient discomfort. [jgo.amegroups.com]
Workup
PET-CT Recent research suggests that there are grounds for using PET-CT routinely in the workup of anal cancer, as it alters the initial staging sufficiently frequently 4. [radiopaedia.org]
Workup for Anal Canal Cancer • PET imaging is useful in further evaluating the extent of the primary tumor and the presence of regional lymph node metastases, and distant metastases, as well as in evaluating the response to therapy. • For patients with [slideshare.net]
Treatment
After 2 years, 40% of patients with multimodal treatment and 20% of those without ablative treatment were alive. LIMITATIONS: This study is limited by its retrospective design and modest sample size. [ncbi.nlm.nih.gov]
Prognosis
CONCLUSION: AA confers a significantly worse prognosis than SCCA and RA. Copyright © 2016 Elsevier Inc. All rights reserved. [ncbi.nlm.nih.gov]
Prognosis of Anal Cancer (Squamous Cell Carcinoma of the Anus) Anal cancer prognosis depends upon the size of the anal tumour, where the anal tumour is and whether it has spread to the lymph nodes. [myvmc.com]
They are more common in men and have a good prognosis. Anal canal tumours : are usually poorly differentiated. They are more common in women and have a worse prognosis. The anal canal extends from the anorectal junction to the anal margin. [patient.info]
[…] colorectal SCC be at least 5-7 cm from the anus Squamous Carcinoma of the Anus Perianal Squamous Carcinoma Must involve anal canal ≤5 cm from anal verge and entirely visible outside the anal canal on clinical examination Perianal carcinomas have a better prognosis [surgpathcriteria.stanford.edu]
Etiology
Etiology The most important risk factors for HPV and SCC are behaviors that predispose individuals to HPV infection or immunosuppression. [cancertherapyadvisor.com]
(Etiology) Untreated (or delayed treatment of) squamous cell carcinoma in situ can result in invasive squamous cell carcinoma. [dovemed.com]
Additional hypermetabolic activity was noted in the paraaortic and prevascular lymph node regions, but these findings were thought to be inflammatory in etiology rather than metastatic. [jgo.amegroups.com]

Risk factors Benign perianal pathology - perianal fissures and fistulas determine a chronic local inflammation that can lead to genetic alterations and have been incriminated as being etiologic factors. [medichub.ro]

Methods: We used data from the Surveillance, Epidemiology, and End Results (SEER) registry linked to Medicare claims to evaluate outcomes among a cohort of male HIV+ and HIV- patients diagnosed with SCCA from 1997 to 2009. [croiconference.org]
Pathophysiology

A further complication is that pathophysiologically, cancer of the anal margin (perianal skin) may be more closely related to penile and vulvar cancers than to cervical cancer, and the former are much less well studied than the latter. [10] In current [emedicine.medscape.com]

In the future, cytological screening of male homosexuals with an anal Papanicolaou test may help in identifying high-grade dysplasia and preventing anal cancer. [ncbi.nlm.nih.gov]
What is prevention? Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. [northshore.org]
