Mouth floor cancer

The generic name of tumor occurring in floor of mouth in one of oral cancer with the mouth floor cancer (air strategy cancer to ask for, mouth floor cancer). Occupy 10% - 28% of the whole oral cancer [¹]; [²] [³].

Concept

Mouth floor cancer is tumor which is relatively frequent in oral cancer for a tumor occurring in floor of mouth. Because it is a visible range, the early detection is easy, but when there are not subjective symptoms, I am left unattended and may usually consult medical institutions after a tumor progressed.

Cause

The details refer to "oral cancer # epidemiology"

Epidemiology

In the 1930s, the current sex ratio is done [⁴] that 13:1 and the woman had little sex ratio with approximately 4:1 [¹], and the ratios of female patient increase. About this, the drinking of the woman, increase of the smoking are suggested as a cause [⁴].

It appears most commonly near sublingual caruncle [¹].

Symptom

I form a mass with the oral fundal ulcer and induration.

Lymph node metastases are easy to occur along with tongue cancer from an early stage, and about half of patients have already metastasized to lymph node at the time of the first medical examination [¹].

Inspection

Other than the pathological examination of the tumor part, CT, MRI, PET, US, a chest radiograph, Ga scintigraphy, bone scintigraphy, upper part gastrointestinal tract endoscopy, an examination of gastrointestinal contrasting are carried out as video diagnosis of a nuclear power generation part and the metastasis part [⁵].

Treatment

Or a surgical treatment, radiotherapy, a cure for chemotherapy are provided by a combination alone. In addition, except an early thing, art of rebuilding is carried out when I choose a surgical treatment.

In addition, for lymph node metastases, neck dissection is performed.

Because the functions such as eating, deglutition, starting words decrease after treatment, rehabilitation is performed by a doctor, a dentist, a language hearing person, a dental hygienist, nurses.

Clinical department

A clinical department in charge of includes head and neck surgery mainly at oral surgery and otolaryngology, the National Cancer Center. In addition, a charge clinical department (chemotherapy department) is concerned by the chemotherapy radiology by the radiation therapy plastic surgery when the rebuilding is necessary. In addition, the rehabilitation section including the language hearing person participates, too.

Convalescence

I am said to be a survival rate for 70% - 80% of five years. ^[1]
