A Global Record of Patients With Anal Squamous Cell Carcinoma With and Without HIV Infection (ACTION HIV)

August 26, 2026 updated by: Latin American Cooperative Oncology Group

ACTION HIV (Anal Cancer TherapIes and Outcomes iNitiative for Patients Living With and Without HIV): A Global Record of Patients With Anal Squamous Cell Carcinoma With and Without HIV Infection

Due to the scarcity of data on prognostic and predictive influence on CCA, epidemiological studies evaluating these factors need to be developed in patients with CCA. Therefore, the investigators want to evaluate the profile of patients in the real world and from various parts of the world, describing prognostic factors such as CD4 dosage, time of HIV infection, evaluation of viral load, diagnosis of AIDS, geographic region of diagnosis and treatment, clinical staging, medications concomitant with QRT (risk of drug interactions), comorbidities (possible impact on dose-intensity), use of HAART, time of use of HAART, radiotherapy modality (conventional 3D vs Modulated Beam Intensity [IMRT], response to Nigro vs CTII regimens, as well as comparing clinical outcomes with patients without HIV infection.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Median disease-free survival
Time Frame: 3 years
Defined as time from Day 1 from initiation of treatment (or definition of exclusive supportive care) to tumor death or recurrence. Disease-free survival at 3 years after initiation of treatment: proportion of patients free of local or metastatic disease at 3 years after treatment termination according to imaging tests (chest, abdomen and pelvis scans) and clinical examination of anal inspection
3 years
Complete clinical response
Time Frame: 6 months
Absence of neoplasia on magnetic resonance imaging (preferred) or computed tomography of the pelvis and on clinical examination of anal inspection 6 months after the end of QRT or RT isolated
6 months
Overall survival
Time Frame: From first date of treatment to date of death from any cause, assessed up to 3 years.
Defined as the date from the D1 of treatment (or exclusive supportive care) to death from any cause; living patients at the time of the analysis will be censored.
From first date of treatment to date of death from any cause, assessed up to 3 years.
