Introduction

Head and neck cancer is a collective name for all of the cancers located in the head and neck area except the brain and eyeball. They may occur in various locations and comprise upper aerodigestive tract anatomic sites. They represent the third most common cause of cancer death worldwide. A 2018 analysis estimated 550,000 head and neck cancer cases worldwide and over 330,000 deaths from the disease yearly [1, 2]. Data from the Nationwide Head and Neck Cancer Prevention Programme indicate that peak morbidity occurs in patients between 55 and 64 years old. Among patients suffering from head and neck cancer, 60% seek medical attention too late, in III and IV clinical stages of cancer. The majority of them die within five years from diagnosis [3].
The development of head and neck cancer is the result of the interaction between environmental factors and genetic inheritance and is, therefore, multifactorial. Smoking and alcohol consumption are the leading risk factors for the development of this disease [2]. However, in the last decade increased incidence of throat, larynx, tongue, and salivary gland carcinoma was observed among young people, under 40 years old, who are nonsmokers and not extensive alcohol consumers [3]. Epidemiological studies indicate a close relationship between the development of middle throat tumors (palatine tonsil, the root of the tongue) and human papillomavirus infection, which is transmitted sexually, and which is the main risk factor in young adults [4]. As reviewed by Galbiatti et al., symptoms of head and neck cancer are often confused with symptoms that occur in colds. They consist of: tongue pain, untreated mouth ulcers, white and red spots on the tongue, sore throat, persistent hoarseness, problems with swallowing, neck tumor, one side stuffed nose, and bleeding from the nose [5]. Due to the “1 for 3 Scheme”, which reveals risk factors related to head and neck cancer, in case of the persistence of one of these symptoms for longer than three weeks a general practitioner should direct the patient to a laryngologist. Early diagnosis and non-invasive treatment allow 95% of patients to return to work with a good quality of life [6].

Laryngeal cancer in Poland

After the Second World War, the Polish population experienced a dramatic increase in the rates of head and neck cancer, especially laryngeal cancer morbidity and mortality. Laryngeal cancer became one of the most frequent malignant neoplasms in the world. The main reason for it was a dramatic increase in tobacco and alcohol consumption after 1945 [7, 8]. In response, the Polish Government asked the Radium Institute (which was created by Maria Curie Skłodowska in 1932) to prepare a National Cancer Control Program. In the 1970s the Polish government built in Warsaw a Comprehensive Oncological Center, which consisted of basic cancer studies departments, departments for cancer registration and epidemiology, as well as departments for primary and secondary cancer prevention. The main part of the Center was the 700 beds strong oncological hospital. This hospital was organised according to human topography and specific organs. For example, in the Head and Neck Department, there were doctors specialized in laryngology, radiotherapy, chemotherapy, surgery etc. This allowed a comprehensive approach to diagnostics, treatment, and rehabilitation from different cancers [8].
The epidemiological part of the Comprehensive Cancer Control Program in Poland – PR7 – was formulated under the leadership of one of the directors of Cancer Institute, Professor Tadeusz Koszarowski, in collaboration with WHO International Agency for Research on Cancer in Lyon (IARC). Dr. Calum Muir, the former epidemiological director of IARC, advised that one of the first research fields of cancer epidemiology in Poland should be laryngeal cancer. This was in relation to the dramatic increase of laryngeal cancer morbidity and mortality in the male population in Poland at the time [9-14]. In the early 1980s, Dr. Witold Zatoński was invited and employed by prof. Tadeusz Koszarowski to coordinate the PR7 program in the field of cancer etiology, cancer regis­tration and epidemiology, and primary and secondary cancer prevention. He in turn invited Profesor Stanisław Iwankiewicz, a pioneer of laryngeal cancer research in Poland, the rector of Wrocław Medical University, and the director of its Department of Laryngology, to join the collaboration on one of the most crucial parts of the PR7 program by taking the lead on a laryngeal cancer control national project. Finally, Prof. Stanisław Iwankiewicz invited two other outstanding Polish ENT (Ear, Nose, Throat) groups led by prof. Jan Kuś from the Department of Head and Neck Surgery of CMKP (Medical Center for Postgraduate Education) in Warsaw [9] and prof. Tatiana Gierek, from the Department of Head and Neck Surgery of the Silesian Medical University to join this project [15]. Prof. Iwankiewicz has established a group of researchers led by Dr. Irena Baran and consisting of two outstanding ENT physicians Dr. Jerzy Rak and Dr. Dariusz Zatoński. The first achievement of this group was the organization of a registry of laryngeal cancer for the district of Lower Silesia. At this time it was one of the first population-based laryngeal cancer registries in Europe. The registry’s database was developed in collaboration with the Wrocław Technical University and Wrocław Computer Factory – it was one of the few international cancer registries to be digitalized at the time [9, 16, 17].
The project has laid the groundwork for all the laryngeal cancer research in Poland and was accompanied by a series of high-quality scientific publications. Prof. Iwankiewicz’s work led to the establishment of proven tools to study, diagnose, prevent and treat laryngeal cancer. The team also conducted the very first case-controlled population-based study in Poland using the population of Lower Silesia as a control sample. Among other papers, they were a base for many PhD theses [18-30]. Having in mind this pioneer history of larynx cancer research, the Wrocław Medical University has been a epidemiological and oncological science hub for nearly forty years now. It led numerous important laryngeal cancer studies which resulted in internationally published and acclaimed papers. Today under the Leadership of prof. Tomasz Zatoński the Department of Laryngology, Head and Neck Surgery at Wrocław Medical University remains one of the leading Polish laryngeal research centers [31]. The team present at the Department of Otolaryngology, Head and Neck Surgery of Wrocław Medical University is continuing the grounbreaking historical work. One of such recent endeavours was the 2019 Oral, Head and Neck Cancer Awareness Week, the results of which are discussed in this article [6].

MAterial and methods

Oral, Head and Neck Cancer Awareness Week, led by the Head and Neck Cancer Alliance is a weeklong series of events promoting awareness of oral, head, and neck cancer, accompanied by a day of free cancer screenings. Wrocław University hospital has participated in the program by preparing meetings, presentations and inviting patients for the screenings in September 2019 at the Head and Neck Surgery Department. During that week 37 people presented to the University Clinical Hospital in Wroclaw. As a result of the interview and initial survey, ten people (six women and four men) were excluded from the screening due to a lack of risk factors. Twenty-seven people, 12 women, and 15 men qualified for further laryngological consultation. During the ENT consultation, subjects filled out a Patient Concerns Inventory (PCI) questionnaire, which assessed the physical and functional well-being, social, mental, and emotional health problems. The patient could select several problems that he wanted to discuss during the visit. The survey has been translated into Polish. and validated in the experimental group. PCI questionnaire was designed in the University of Washington and is known as UW‐QOLv4 [32]. Polish version of the UW-QoLv4 questionnaire seems to have been translated well, is valid, and is valuable for the assessment of the quality of life among Polish patients with cancers of the head and neck [33]. PCI is a way of alerting clinical teams as to which patients need additional support [34]. In this programme the paper version of the PCI questionnaire was used and then a database containing the answers of patients was created. 

Results

Social interviews of patients reported twenty-six people with secondary education, seven people with higher education, two people with a bachelor’s degree, one person with matriculation and basic vocational education. Twelve people worked non-manually, five manually and twenty did not work. Patients reported learning about the head and neck cancer prevention initiative from the media – 46%, from their primary care physician – 13% and from other sources – 41%. The most common symptoms reported are hoar­seness (43% of people) and burning in the throat and mouth pain (35%). Fifteen people reported bleeding during brushing their teeth. Thirteen respondents felt an unpleasant smell from their mouths. The feeling of dry mouth is reported by ten people. One person reported complaints such as spontaneous bleeding when speaking or eating, increased tooth mobility and swollen gums. 46% of the respondents have dentures.
Fifteen people reported to be smokers, three people quit smoking and six smoke e-cigarettes. The second carcinogen is alcohol consumption. Forty-six percent of those surveyed do not drink alcohol, and fifty-four percent drink occasionally (20 people). Fifty-seven percent of people had a history of cancer in the family. Four people had cancer themselves, including one in the head and neck. Respondents visit the dentist at various frequencies: ten people every six months, fifteen people once a year, eleven less than once a year, and one person did not answer. The frequency of brushing teeth varies more: 68% of respondents brush their teeth twice a day, three and more times a day – 24% and only once a time – 8%. The patients were aged between 21-84 years old. The study sample characteristics are summarized in Table 1.
Symptoms that led to a visit during the prevention program are hoarseness (60%), burning in the mouth (45%), swallowing problems (20%), and other (30%). Ten people smoke cigarettes, one quit smoking about fifty years ago. Three respondents drink alcohol one to two times a week, five occasionally and twelve people declare that they do not consume alcohol at all. To the question about the number of life sexual partners, the respondents answered: up to three (80%), from three to seven (10%), above seven (5%) and 5% did not answer the question. Thirteen people in the family had cancer, including two in the head and neck. Two qualified people had cancer, including one with head and neck cancer. During the visit, subjects filled out a PCI questionnaire, which assessed the physical and functional well-being, social, mental and emotional health problems. The answers are presented in the Table 2. The biggest concern on the part of respondents was pain in the neck and head area (40% of patients). Other factors are: phlegm (35%), dry mouth (25%), swallowing (25%), cough (25%), breathing (20%), fatigue (20%) and sleeping (20%). Other issues that patients wanted to talk about were: intestinal problems (like a bowel and a diarhoea constipation – 15%), shoulder (also 15%) and depression (10%), deal (10%), swelling (10%) and hearing (10%). All concerns that patients wanted to raise during the ENT visit were presented in Figures 1 and 2.
In the experimental group, there were no ear diseases. Only one person had a plug of earwax. After throat laryngological assessment it was found that three people had tonsillectomy (15%), two had papillomas present on the palatopharyngeal arch (10%), one person had raid in the mouth (5%), cleft palate in the area of the tongue, hemangioma of the root tongue (5%), pre-epiglottic cyst (5%) and hypertrophy of the root tongue (5%). Larynx endoscopy showed one case of vocal folds dysfunction, swelling of the interarytenoid area, hyperplasia of false vocal cords and Reinke’s edema (Fig. 3). The study has shown a middle cyst of neck, thyroid nodules, and parotid gland tumors among the surveyed patients. The salivary gland tumor imaging was sent for radiological diagnostics and then qualified for surgery in the Department of Otolaryngology. The most common diagnosis on the assessment of the nose in this group of patients was nasal septum deviation – which was found in as many as 30% of the respondents (n = 6), including one with a perforated septum. Allergic mucosal edema was observed in one person. One patient was qualified and operated at the Otolaryngology Clinic, and one is under the constant supervision of a specialist.

Discussion

The PCI has shown that respondents wanted to talk about symptoms that are related to head and neck cancer risk factors. Symptoms include mainly: coughing (25%), phlegm (35%), dry mouth (25%), hearing (10%), tiredness (20%), pain in head and neck (40%), swallowing (25%). Despite the fact that patients reported to the Clinic with physical problems related to Head and Neck cancer genuine need for mental, emotional and spiritual support was revealed. Respondents want to talk about problems as: depression (10%), anxiety(5%), dealing with problems (10%), anger (5%), memory(5%).These results indicate the fact that psychological support is indispensable in diagnosis and prevention of Head and Neck cancer.  Subjects either did not notice correlation or it was not relevant for them to talk about factors as: lifestyle and habitat, indigestion, mobility, cancer treatment, PEG tube, wound healing, financial benefits, home care/district nurse, recreation, relationships, appearance, fear of cancer coming back, fear of adverse events, intimacy, mood, self-assessment, sex, religious aspect, temperament and personality. Reluctance to provide answers could have been potentially caused by lack of access to information about cancer treatment. Superstitious beliefs and illiteracy may also be contributory factors [34].
Among experimental group cases of the following diseases were detected: papillomas on the palatopharyngeal arch (2), raid in the mouth (1), hemangioma of the roof of the tongue (1), pre-epiglottic cyst (1), hypertrophy of the roof of the tongue (1). The research shows a correlation between risk factors and presented diseases. Major risks factors include smoking and alcohol abuse.  Despite the correlation between risk factors and head and neck diseases the research shows that in some cases risk factors do not contribute to the development of the disease. As an example among the experimental group there was one patient who smoked more than 16 cigarettes per day, but the ENT study did not reveal any hypertrophic changes, only nasal septum deviation which is not associated with smoking.

Conclusion

The PCI questionnaire is a practical tool in Cancer Prevention Programmes. This questionnaires inform the doctor about general health issues of the patient. The research shows that the most important part of prevention is continuous education of all patients. Additionally, prophylactic tests may ensure success in oncological diagnosis and treatment.
