Differential Mobility Spectrometry (DMS) Based Oral Tumor Analysis
Study Purpose
The trial is a single-center, non-randomized feasibility study aiming to evaluate the feasibility of ex-vivo tissue analysis using differential mobility spectrometry (DMS) of tissue smoke generated by the use of an electrosurgical instrument. Patients recruited in the trial receive standard-of-care oral squamous cell carcinoma tumor excision surgery.
Recruitment Criteria
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Trial Details
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

Oral squamous cell carcinoma is the sixth common carcinoma and the cause of 1-2% of cancer related deaths in the world. The incidence of oral squamous cell carcinoma was 255 cases in Finland and 742 270 cases worldwide in year 2015. The number of cases per year has been increasing. The approximate age of tumor occurrence is usually between 60
- - 70 years.
The 5-year survival rate of all diagnosed oral squamous cell carcinoma cases in Finland during the years between 2014 and 2016 was 67% for women and 61% for men. Early diagnostics is relevant, since oral squamous cell carcinoma tumors have a tendency to grow rapidly and metastasize early to regional lymphnodes and later on to lungs, liver and bones. Typical locations of the tumor are tongue, gums and sole of mouth. The primary treatment option for oral squamous cell carcinoma is surgical removal of the tumor with 0,5- - 1cm healthy tissue margin.
The aim of the operation is to remove the tumor entirely so that the healthy tissue margins are as sparing as possible and that the functional and cosmetic outcomes are as satisfactory as possible. Sufficient healthy tissue margin is one of the most important prognostic factors. Nevertheless, there is only little evidence based knowledge of sufficient healthy tissue margins. Differential mobility spectrometry (DMS) based application called automatic tissue analysis (ATAS) can be utilized to identify tumor cells from healthy tissue. Tissue identification is done by analyzing tissue smoke that is generated by the use of an electrosurgical instrument called diathermy. The objective of the trial is to test whether it is possible to identify oral squamous cell carcinoma tissue from normal oral mucosa by using ATAS. A 4mm punch biopsy of an oral squamous cell carcinoma tumor and a control biopsy of healthy oral mucosa will be collected from 30- - 40 patients undergoing oral tumor excision.
The biopsies will be examined in the research laboratory with ATAS to test tissue recognition.Arms

Interventions
Procedure: - Punch biopsy
Punch biopsy of oral squamous cell carcinoma tumor and a control biopsy of healthy oral mucosa are collected during primary tumor excision surgery from each recruited patient.
