The use of cellular telephones has increased dramatically during the 1990's in the world. In the 1980's the analogue NMT system was used whereas the digital GSM system was introduced in early 1990's and is now the preferred system. Case reports of brain tumours in users initiated this case-control study on brain tumours and use of cellular telephones. Also(More)
Patients with human papillomavirus DNA positive (HPV(DNA+)) oropharyngeal squamous cell carcinoma (OSCC) have better clinical outcome than those with HPV DNA negative (HPV(DNA-)) OSCC upon intensive oncological treatment. All HPV(DNA+) OSCC patients may not require intensive treatment, however, but before potentially deintensifying treatment, additional(More)
In the county of Stockholm, between 1970 and 2002, we have previously reported a 3-fold parallel increase in the incidence of tonsillar squamous cell carcinoma (SCC) and the proportion of human papillomavirus (HPV) positive tonsillar SCC. Here, we have followed the above parameters in all patients (n = 120) diagnosed with tonsillar SCC during 2003-2007 in(More)
Numerous reports have shown that the incidence for oropharyngeal cancer is increasing and that human papillomavirus (HPV) is a risk factor. However, few studies have investigated the specific subsites of the oropharynx. Following our previous research on tonsillar cancer, we assessed the increase in the incidence of base of tongue cancer and the prevalence(More)
Patients with human papillomavirus (HPV) positive tonsillar and base of tongue squamous cell carcinoma (TSCC and BOTSCC, respectively) have a better clinical outcome than those with HPV negative tumours, irrespective of treatment. However, to better individualise treatment, additional biomarkers are needed together with HPV status. In a pilot study, we(More)
The aim of this review is to present the current knowledge on the status and significance of human papillomavirus (HPV) in tonsillar cancer. An increase in the incidence of tonsillar cancer has been reported and recent data suggest that this increase is due to an increased proportion of HPV in these tumours. Furthermore, patients with HPV positive cancer(More)
Patients with cancer of unknown primary (CUP) in the head neck region are generally treated with neck dissection followed by radiotherapy at times combined with chemotherapy, a treatment associated with considerable side effects. Some of these tumors may originate as human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OSCC), with(More)
From 1970 to 2002 in the Stockholm area, we revealed a parallel three-fold increase in the incidence of tonsillar cancer and the proportion of human papillomavirus (HPV) positive tonsillar cancer cases, indicating a possible role of HPV infection in this disease. We have now examined whether HPV and viral load in pre-treatment tonsillar cancer biopsies(More)
BACKGROUND Human papillomavirus (HPV) is a risk factor for tonsillar squamous cell carcinoma (TSCC) and the presence of HPV is correlated to a better clinical outcome. To find additional biomarkers that, together with HPV, predict clinical outcome, the aim of the present study was to evaluate epidermal growth factor receptor (EGFR) and phosphorylated EGFR(More)
BACKGROUND Human papillomavirus (HPV) is a causative factor for tonsillar squamous cell carcinoma (TSCC) and patients with HPV positive (HPV(+)) TSCC have a better clinical outcome than those with HPV negative (HPV(-)) TSCC. However, since not all patients with HPV(+) TSCC respond to treatment, additional biomarkers are needed together with HPV status to(More)
