- Pattern of occurrence and treatment outcome of second primary . . .
Warren and Gate's criteria have been used to designate a case as multiple primary tumors, and the prerequisites are as follows: (1) Each of the tumors must be histopathologically confirmed, (2) each must be geographically separated and distinct, and the lesions should be separated by normal mucosa, (3) probability of one being the metastasis of
- Synchronous and Metachronous Cancers: An Update
According to Warren Gates criteria a diagnosis of MPM require the following criterias to be fulfilled (a) each tumor should present a definite picture of malignancy (b) each tumor should be histologically distinct (c) the possibility that one is metastasis of the other must be excluded [2]

These criteria, particularly the third, can be difficult to satisfy This problem is illustrated in an article written by Hordjik and De Jong7 that addressed the problem of bronchogenic carcinoma related to carcinoma of the larynx

Currently, for designating such non-concurrent malignant lesions of any organ, oncologists and researchers around the globe use one of four distinct sets of guidelines, all of which are based on arbitrary clinical parameters
- Second primary tumors and field cancerization in oral and . . . - PubMed
In most studies the definition of SPT is based on the criteria of Warren and Gates, published in 1932 These criteria, however, are ill-defined and lead to confusion Recent molecular studies have shown that a tumor can be surrounded by a mucosal field consisting of genetically altered cells
- Warren, S. and Gates, O. (1932) Multiple Primary Malignant Tumors A . . .
ABSTRACT: Double primary malignancies could be divided into two categories, depending on the interval between tumor diagnoses A secondary malignancy could be defined as a new cancer that has occurred as a result of previous treatment with radiation or chemotherapy Second primary malignancy can occur at any age but it’s commonly at old age
- Second primary malignancies in patients with head and neck cancers
Patients with head and neck squamous cell carcinoma (HNSCC) are at increased risk for the development of a second primary malignancy (SPM), which is defined as a second malignancy that presents either simultaneously or after the diagnosis of an index tumor
- Second Primary Tumours in Head and Neck Cancer - ScienceDirect
Warren and Gates’ Criteria of Second Primary Tumour Post-treatment follow-up of patients with ECHN is based on control of the primary and the neck, but as time passes the diagnosis of an SPT or distant metastasis becomes more relevant as the risk of local or regional relapse reduces
