Introduction: Limited data exist regarding head and neck cancer (HNC) burden among immigrants who may have distinct characteristics, and hence different incidence rates from the general population. Variations in behavioral habits, cultural lifestyle, or diet may cause variations across different subgroups., Methods: The whole immigrant population of Finnish residents born abroad, and their children were retrieved for the years 1970-2017. First-generation immigrants are defined as individuals born abroad, excluding their children (even if born abroad). The study comprised 0.5 million first-generation immigrants and 0.3 million children, contributing to 6 million and 5 million person-years of follow-up, respectively. Standardized incidence ratios (SIR) and excess absolute risk (EAR) per 100,000 person-years at risk were calculated to quantify the risk of HNC among immigrants relative to the general Finnish population., Results: The overall risk of any HNC was not increased among first-generation male immigrants (SIR 1.00, 95% CI: 0.88-1.15), but significantly elevated for cancer of the pharynx (SIR 1.56, 95% CI: 1.22-1.95), and larynx (SIR 1.38, 95% CI: 1.02-1.83) and decreased for lip (SIR 0.38, 95% CI: 0.20-0.67). The increased risk of pharyngeal cancer was highest among male immigrants from Asia Pacific (SIR 4.21, 95% CI: 2.02-7.75). First-generation immigrant women had a significantly reduced risk of any HNC (SIR 0.45, 95% CI: 0.37-0.55), which remained even after stratification by site. We observed no increased risk of any HNC among the children of first-generation immigrants., Conclusion: Healthcare professionals need to recognize the groups at higher HNC risk. Efforts to address the main etiological risk factors, such as smoking, are needed among the selected immigrant populations, that haven't yet reached similar decreasing trends, as in for example smoking, as the main population.NOVELTY AND IMPACTCurrently, globally, over 280 million people live outside their country of birth. Limited data exist regarding head and neck cancer (HNC) burden among immigrants who may have distinct characteristics and hence different incidence rates from the general population. Immigrant studies can provide novel data by shedding light on risk alterations and the pace of acculturation of different populations.

Background: Reported patterns of familial aggregation of head and neck cancer (HNC) vary greatly, with many studies hampered by the limited number of subjects., Methods: Altogether 923 early-onset (≤40 years old) HNC probands, their first-degree relatives, spouses, and siblings' offspring were ascertained. Cumulative risk and standardized incidence ratios (SIRs) were estimated., Results: Of all early-onset HNC families, only 21 (2.3%) had familial HNC cancers at any age and less than five familial early onset HNC cancers among first-degree relatives. The cumulative risk of HNC for siblings by age 60 (0.52%) was at population level (0.33%). No increased familial risk of early-onset HNC could be discerned in family members (SIR 2.68, 95% CI 0.32-9.68 for first-degree relatives)., Conclusions: Our study indicates that the cumulative and relative familial risk of early-onset HNC is modest in the Finnish population and, at most, only a minor proportion of early-onset HNCs are due solely to inherited genetic mutations., (© 2020 The Authors.

Background and aims: Stage II cancer of the tongue is mostly managed surgically both locally and regionally. However, indications for postoperative radiotherapy and reconstructive options vary between centers. This paper aims to describe differences in treatment in a geographically homogenous cohort. Methods: A retrospective comparison was made between two cohorts of clinical T2N0 tongue cancer from Finland and Sweden. The Finnish cohort included 75 patients and the Swedish 54. All patients had curative intent of treatment and no previous head and neck cancer. Data analyzed consisted of pathological stage, size and thickness of tumor, frequency of reconstruction, radiotherapy delivered, and survival. Results: The Finnish cohort included a higher proportion of patients managed with reconstructive surgery (67%) than the Swedish cohort (0%), p  < .00001. More patients were treated with postoperative radiotherapy (84%) in the Swedish cohort than in the Finnish (54%), p  < .0002. The Finnish cohort had a higher level of survival and included more frequent downstaging (cTNM to pTNM). Conclusions and significance: Our data indicate a major difference in the management of T2N0 oral tongue cancer. The optimal cut-off size and growth pattern of the tumor warranting reconstruction should be further evaluated in a prospective manner considering both survival and quality of life.

Purpose: Late-stage OTSCC is associated with poor overall survival (OS). Non-curative treatment approach aims to improve quality of life and prolong survival of patients deemed incurable. The purpose of this study was to investigate the used non-curative treatment modalities for OTSSC and patient survival., Methods: All patients diagnosed with OTSCC and treated with non-curative intent at the HUS Helsinki University Hospital (Helsinki, Finland) during the 12-year period of 2005-2016 were included. Survival analysis after the non-curative treatment decision was conducted using the Kaplan-Meier method in this population-based study., Results: Eighty-two patients were identified. A non-curative treatment decision was made at presentation without any previous treatment in 26 patients (7% of all patients diagnosed with OTSCC during the study period). Palliative radiotherapy was administered to 24% of all patients. The average survival time after the non-curative treatment decision was 3.7 months (median 2 and range 0-26)., Conclusions: Due to the short mean survival time after decision for treatment with non-curative intent, and the notable symptom burden in this patient population, a prompt initiation of all non-curative measures is warranted.
