BACKGROUND: Guidelines for anal cancer recommend assessment of response at 6-12 weeks after starting treatment. Using data from the ACT II trial, we determined the optimum timepoint to assess clinical tumour response after chemoradiotherapy. METHODS: The previously reported ACT II trial was a phase 3 randomised trial of patients of any age with newly diagnosed, histologically confirmed, squamous cell carcinoma of the anus without metastatic disease from 59 centres in the UK...

Intravenously administered for the treatment of rectum cancer, irinotecan produces severe side effects due to very high plasma concentrations. A novel irinotecan-encapsulated double reverse thermosensitive nanocarrier system (DRTN) for rectal administration was developed as an alternative. The DRTN was fabricated by dispersing the thermosensitive irinotecan-encapsulated solid lipid nanoparticles (SLN) in the thermosensitive poloxamer solution. Its gel properties, pharmacokinetics, morphology, anticancer activity and immunohistopathology were assessed after its rectal administration to rats and tumor-bearing mice...

: 222 Background: Rolapitant (VARUBI) is a selective, long-acting neurokinin-1 receptor antagonist (RA) for the prevention of CINV. Rolapitant effectively prevented CINV in phase 3 trials of patients (pts) receiving highly or moderately emetogenic chemotherapy (HEC, MEC). While MEC and HEC regimens are commonly used to treat pts with gastrointestinal and colorectal cancers (GI/CRC), very few studies have evaluated the effectiveness of a neurokinin-1 RA regimen in these pts. We assessed the incidence of CINV and efficacy of rolapitant in a subset of pts with GI/CRC...

The patient was a 53-year-old man who complained of perianal pain. He had a 20-year history of an anal fistula. There was a 10 cm tumor with mucin-like discharge on the left side of the anus. His CEA level was high, at 7.3 ng/mL, and T2-weighted MRI revealed a multilocular cystic tumor with high signal intensity. The second biopsy result indicated mucinous adenocarcinoma. We performed neoadjuvant chemoradiotherapy. The chemotherapy regimen was TS-1 with radiation therapy, along with 4-port irradiation(50.4 Gy)of the primary tumor, located at the interior of the pelvis and inguinal lymph nodes...

RATIONALE: Patients with human immunodeficiency virus (HIV) infection have been shown to be at increased risk for high-risk human papillomavirus (HR-HPV) infection of the anogenital tract. Furthermore, in the last decades, the introduction of highly active antiretroviral therapy (HAART) has increased the longevity of these patients who now live long enough to develop HPV-related cancers; hence, the impact of HPV infection on HIV-positive patients is of increasing concern. PATIENT CONCERNS: We reported the case of an HIV-positive female patient on HAART with a good virological and immunological response and with a long history of HPV-related intraepithelial and invasive lesions of the anogenital tract...

BACKGROUND: Hepatitis C virus (HCV) infection causes hepatocellular carcinoma (HCC) and subtypes of non-Hodgkin lymphoma (NHL). Associations with other cancers are not established. The authors systematically assessed associations between HCV infection and cancers in the US elderly population. METHODS: This was a registry-based case-control study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data in US adults aged ≥66 years. Cases (n = 1,623,538) were patients who had first cancers identified in SEER registries (1993-2011)...

BACKGROUND AND AIMS: Laparoscopic resection is a well-established approach for colorectal cancer surgery. In patients with rectal cancer treated by neoadjuvant chemoradiotherapy, it may be difficult to identify a clear safety margin for endostapling and subsequent anastomosis. We designed an innovative technical approach to assist colorectal anastomosis in these patients. TECHNIQUE: A four-trocar laparoscopic approach is used. After exploration of the abdominal cavity, the left colic flexure is completely mobilized...

PURPOSE: Anorectal gastrointestinal stromal tumors (GISTs) are exceedingly rare, and management remains controversial in regard to local resection (LR) and preoperative chemotherapy. METHODS: The National Cancer Data Base was queried from 1998 to 2012 for cases of GIST resection in the rectum or anus. Patient demographics, type of surgery (LR vs. radical excision [RE]), short-term outcomes, and overall survival (OS) were analyzed. Preoperative chemotherapy was recorded following the US FDA approval of imatinib in 2002...

Squamous cell carcinomas of the anus and anal canal represent a model of a cancer and perhaps the first where level 1 evidence supported primary chemoradiotherapy (CRT) in treating locoregional disease with curative intent. The majority of tumours are associated with infection with oncogenic subtypes of human papilloma virus and this plays a significant role in their sensitivity to treatment. However, not all tumours are cured with CRT and there remain opportunities to improve outcomes in terms of oncological control and also reducing late toxicities...

REVIEW
Rob Glynne-Jones, Sheela Rao
Radical concurrent chemoradiotherapy with 5-fluorouracil and mitomycin C (MMC) remains the standard of care for squamous cell carcinoma of the anus. Phase III trials over 2 decades have used combined radiation doses of 50 to 60 Gy with concurrent fluoropyrimidines, MMC, or cisplatin in various doses and schedules. Modern radiotherapy techniques allow the production of highly conformal plans, decreasing radiation doses to the organs at risk and ensuring a shorter overall treatment time without the need for treatment breaks...

Human papillomavirus (HPV) infection significantly impacts women, as it can cause cancers and precancers of the cervix, vulva, vagina, oropharynx, and anus. However, many of these cancers can be prevented by HPV vaccination. Despite evidence of vaccine effectiveness and safety, vaccination rates remain low. Evidence-based strategies should be utilized to reduce barriers and increase vaccination rates.
