1It is of great clinical importance to identify simple prognostic markers from preoperative 2 biopsies that could guide treatment planning. Here, we compared tumor budding (B), depth 3 of invasion (D) and the combined scores (i.e. BD histopathologic model) in preoperative 4 biopsies and the corresponding postoperative specimens of oral tongue squamous cell 5 carcinoma (OTSCC). Tumor budding and depth of invasion were evaluated in the pre-and 6 postoperative samples from 100 patients treated for OTSCC. Sensitivity and specificity 7 statistics were used. Our results showed statistically significant (P< 0.001) relationship 8 between pre-and postoperative BD scores. There was an agreement between the pre-and 9 postoperative BD model scores in 83 cases (83%) with 57.1% sensitivity (95% CI: 39.4% 10 to 73.7%) and 96.9% specificity (95% CI: 89.3% to 99.6%). Our findings suggest that the 11 BD model, analyzed from representative biopsies, could be used for the treatment planning 12 of OTSCC. 13 14 15

The outcome of oral tongue SCC has significantly improved in Finland. However, the relatively high number of disease recurrences in patients with stage I and II disease, when compared with patients with stage III and IV disease, calls for an investigation of new treatment approaches. © 2017 Wiley Periodicals, Inc.

Background:Oral tongue squamous cell carcinoma (OTSCC) metastasises early, especially to regional lymph nodes. There is an ongoing debate on which early stage (T1-T2N0) patients should be treated with elective neck dissection. We need prognosticators for early stage tongue cancer.Methods:Mice immunisation with human mesenchymal stromal cells resulted in production of antibodies against tenascin-C (TNC) and fibronectin (FN), which were used to stain 178 (98 early stage), oral tongue squamous cell carcinoma samples. Tenascin-C and FN expression in the stroma (negative, moderate or abundant) and tumour cells (negative or positive) were assessed. Similar staining was obtained using corresponding commercial antibodies.Results:Expression of TNC and FN in the stroma, but not in the tumour cells, proved to be excellent prognosticators both in all stages and in early stage cases. Among early stages, when stromal TNC was negative, the 5-year survival rate was 88%. Correspondingly, when FN was negative, no cancer deaths were observed. Five-year survival rates for abundant expression of TNC and FN were 43% and 25%, respectively.Conclusions:Stromal TNC and, especially, FN expressions differentiate patients into low- and high-risk groups. Surgery alone of early stage primary tumours might be adequate when stromal FN is negative. Aggressive treatments should be considered when both TNC and FN are abundant.

BACKGROUND: The incidence and survival of oral squamous cell carcinoma (OSCC) patients have increased in recent years. Understanding their long-term survival aspects is essential for optimal treatment and follow-up planning. Almost one in five cancers diagnosed occurs nowadays in individuals with a previous diagnosis of cancer. METHODS: Patients diagnosed with primary OSCC during 1953-2015 were retrieved from the Finnish Cancer Registry. Both standardized incidence ratios (SIR) and excess absolute risk (EAR) per 1,000 person-years at risk (PYR) of second primary cancer (SPC) were calculated relative to the general population. RESULTS: Among 6,602 first primary OSCC patients there were 640 (10%) SPCs. The SIR for

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.

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.

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<0.00001. More patients were treated with postoperative radiotherapy (84%) in the Swedish cohort than in the Finnish (54%), p<0,0002. 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 cutoff size and growth pattern of the tumor warranting reconstruction should be further evaluated in a prospective manner considering both survival and quality of life.
