The true incidence of multiple cancers is not known, but according to recent studies, it appears to be increasing 8. Annually are diagnosed about , new cases of head and neck cancers all over the world, with a ratio of between men and women 7.

The number of deaths from this disease is around , annually. In men, head and neck cancer is the fourth most common cancer, while in women he is ranked of the ninth 7. Combining both sexes, at global level and in the European Union, squamous cell cancer of the head and neck is ranked sixth in incidence after lung cancer, stomach, breast, colon and cervical and seventh place as mortality in the world 1 , 9 , Other locations are: nasal cavity, pharynx, middle ear, salivary glands, thyroid gland, less soft tissue, bone and cartilage 1 , 2 , 6.

Despite modern treatments and latest medical equipment, the progress regarding survival rate for patients with head and neck cancer had not tremendous growth.

This is due, on the one hand, the high risk of recurrence in these patients and on the other hand, frequent metastasis and development of a second primary cancer, especially in the respiratory and upper digestive tract.

Molecular genetic analysis can differentiate recurrences from second primary tumors Multiple cancers of the head and neck Patients who presented during their life a head and neck cancer and who were treated for it, have a high risk to develop multiple cancers. So, a patient may present during his life, two, tree, four or more cancers, completely separated from each other as histopathological type, place of occurrence, evolution and prognostic.

Most often, second primary tumors following a head and neck cancer, also develops at this level, due to the persistent carcinogenic influence on the mucosa of upper aero-digestive tract, even after termination of exposure to carcinogens factors, due to a genetic instability, chemotherapy and radiotherapy treatments, genetic susceptibility, immune deficiency and prolonged survival after some primary tumors 4 , 11 - First report of synchronous cancers in the same patient belongs to Billroth in , who reported a case of stomach cancer and the second primary cancer in the external ear.

Supratentorial Operative Anatomy

He developed three criteria for the diagnosis of multiple cancers: the two tumors should be different from histological point of view, should grow in different places and the two tumors must produce their own metastasis 16 , In , Warren and Gates have proposed some criteria for the definition of the second primary cancer: tumors have to be malignant and this have to be histologically confirmed, tumors must be separated from normal tissue, non-neoplastic and it must be eliminated the possibility that the second primary tumor to be the metastasis of the index tumor 17 - Hong and colleagues were concerned in especially with the multiple tumors arising in the lung, they stated that any primary tumor that occurs in the lung presenting as a solitary nodule within three years from the original tumor is considered a second cancer until proven otherwise 16 , 19 , Development of multiple malignant lesions can be explained by the so-called "field cancerization", phenomenon that occurs during aero-digestive tract when mucosa at this level is exposed to the same types of carcinogens, if they act consistently and for a long time 8 , 21 , The term "field cancerization" was first used by Slaughter and Southwick, in early , when they studied cancers of the oral cavity.

The authors have not developed a definition, but suggested several criteria to describe the term field cancerization: a Oral cancer develops in multiple areas of precancerous changes.

Organs in which the phenomenon of field cancerization are: squamous cell cancer of the oral cavity, oropharynx and larynx, lung, esophagus, vulva, cervix, colon, breast, bladder and skin With the discovery of molecular genetic studies, there were two hypotheses to explain these findings: abnormal areas represent independent clones with a unique pattern of genetic damage tumors are unrelated genetically speaking and these areas of abnormality are genetically linked and come from a common cell clone cell transformation followed by daughter cell migration and tumor genetic connection 24 , Thus appears the theory of the monoclonal origin beside polyclonal theory.

In the monoclonal theory, malignant tumor cells migrate from the primary carcinoma and form foci development potential of secondary carcinoma. Polyclonal theory assumes that secondary independent foci are formed in the mucosa where "field cancerization" is the most severe It is important to differentiate between recurrence and second primary cancer. Risk of relapse in the first three years after treatment of squamous cell cancer of the upper digestive and respiratory tracts is much greater than the risk of second cancers.

After the third year, second primary tumor development is a major cause of morbidity and mortality Multiple cancers are divided into three types, depending when they appear at patients. Notions of synchronous cancers and metachronous were first introduced by Warren and Gates, in , the concept of simultaneously cancers being more recently So, the tumors can be: simultaneous tumor that develops in parallel with the initial tumor; synchronous tumors, which develop within six months of initial cancer diagnosis and metachronous tumors that occur at least six months initial primary tumor development 13 , The risk of second cancer occurs mainly in patients with early stages of initial tumor due to higher survival rate compared with patients in advanced stages.

Also, the risk of second cancer is higher in people younger than 60 years, for the same reasons The risk of death from second primary cancer in patients with early stage head and neck cancer is greater than the risk of death from the original tumor. The prognosis of patients with multiple cancers is dark, those with synchronous tumors with a worse prognosis than patients who develop metachronous tumors Combinations of multiple cancers in ENT area From the above described, there is a fairly high incidence of multiple cancers in patients with head and neck cancer.

These patients may have two or more malignancies, usually all in ENT area. There were no clear reasons to explain the appearance of multiple cancers in one person. Several hypotheses have been developed: the phenomenon may be due to exposure to the same carcinogens most commonly accepted hypothesis , may be due to genetic susceptibility or to an immune compromised, may be due to initial treatment performed to treat the index tumor or be a random appearance For tumors of the upper aero-digestive tract, the most common site of development of the second primary tumor is also the aero-digestive tract.

Patients with aggressive cancers, such as lung cancer have a lower survival rate and therefore rarely develop multiple cancers because the patient does not live enough.

In addition, other cancers, such as Hodgkin's disease and testicular cancer are associated with a high rate of occurrence of multiple cancers due to higher cure and that patients with these cancers are young Patients suffering from cancer of the larynx, squamous cell variant are most likely to develop multiple cancers. Most of the times, the second primary cancer follows a supraglottic cancer, more rarely after a cancer of the glottic three times more frequently in supraglottic cancer than in glottic cancer 30 , 31 , Patients with supraglottic laryngeal tumors have 14 times greater risk of developing lung cancer than the normal population and three times greater risk of developing a second primary tumor in lung those with glottic cancer Therefore, a patient with laryngeal cancer who presents an isolated pulmonary nodule is considered that this is a second primary cancer and not a metastasis, until certainty histopathological diagnosis So, patients with cancer of the floor of mouth and tongue cancer frequently develop second primary cancer In this book, we review the fundamental knowledge of bariatric surgery, including preoperative nutrition, selection, and surgical complication.

In the second part, new emerging and novel procedures are thoroughly described and discussed.
