Background:
The objective of this study is to provide a structured protocol for the treatment of verrucous carcinoma (VC) based on size, bone invasion, recurrence and whether neck dissection is necessary or not. In addition, the study evaluates the probability of a wrong histopathological diagnosis.
Data Sources:
A search was conducted in the Cochrane Library, PubMed and Google from January 1962 to October 2022 by using MeSH terms and keywords. Studies reporting treatment modalities for VC and different histopathological diagnoses after excision of the lesion were selected except case reports and review articles.
Study Eligibility Criteria:
Thirteen articles were selected. Six hundred and thirty cases of VC were treated by surgery, surgery + neck dissection, radiotherapy, chemotherapy and combination therapy. Statistical analysis revealed surgical treatment as a preferred option. Despite being enlarged, the lymph node was negative for metastasis. So, in OVC cases neck dissection adds only unnecessary morbidity to patients.
Participants And Interventions:
Radiotherapy or chemotherapy can be used to downstage the disease. 23.3% of cases reported wrong histopathology diagnosis.
Study Appraisal And Synthesis Methods:
Patients treated for squamous cell carcinoma (SCC) will only experience unnecessary morbidity unless the correct diagnosis is made between VC and hybrid VC. Irrespective of size VC does not metastasise until there are no foci of SCC.
Conclusions:
Surgical excision of T1- and T2-sized lesions can be performed under local anaesthetic as a biopsy procedure. T3 or T4 lesion can be resected with a safe margin. If it comes as hybrid VC or VC with close margin (0.5 cm, <0.5 cm), neck dissection and further margin should be excised as a second procedure respectively.

However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
