“…In contrast, Kirgan and collaborators reported a viral prevalence of 97% in the CRC tissues and 23% in matched normal colon mucosa for HPV, with a significant association between a HPV infection and the CRC risk [ 99 ]. Based on such heterogeneous data, other meta-analyses confirmed a Papillomavirus prevalence of 42–83% in the CRC tissues [ 100 , 101 , 102 , 103 ], and reported ORs of 5-10 for the CRC risk upon infection with HPV [ 104 , 105 ], which is in line with the value of the 4.56 (95% CI: 0.99–21.03) we observed in our study.…”

“…The wide anatomical distribution of HPV infections in tumor tissue with colorectal cancer implies that HPV infection in colorectal cancer is not the result of retrograde viral transmission from the anogenital area and the possibility of hematogenous dissemination is not ruled out. There is evidence of HPV infections in newborns and virgins, which supports that the transmission of HPV through other non-sexual routes may exist [7,[51][52][53][54][55][56]; Since HPV infection is an STI, sexual behavior should be investigated.…”

“…The high percentage of HPV-16 genome integration in the host genome supports the possibility that HPV may have a role in colorectal carcinogenesis. Despite the high prevalence of infection in colorectal tumors with a high-risk type of HPV (HPV-16) and evidence of viral genome integration, HPV infections should be evaluated and whether the E6 and E7 oncoproteins are express and contribute and / or have a causal role in colorectal carcinogenesis [57]; however, it is not enough in the literature to conclude that HPV is a causative agent of colorectal cancer [55][56] as in CaCu [5,[25][26][27][28][29][30][31][32]; HPV has also been detected in precursor lesions of colorectal cancer [6,[57][58][59][60][61][62][63].…”

“…[5][6][7][8][9] HPV infection is associated with benign and malignant diseases such as condyloma acuminatum and respiratory papillomatosis (laryngeal papillomatosis), as well as gastrointestinal, cervical, anal, vulval, vaginal, penile, and head and neck cancers. [10][11][12][13] A high-risk (HR) HPV type (e.g., type 16 or type 18) is likely to cause cervical cell abnormalities that may eventually lead to cancer. 14,15 HR-HPVs were divided into 14 types presented by the CDC, and the remaining types were identified as low-risk (LR) HPVs.…”
