Prognostic significance of lymph node density in squamous cell carcinoma of the tongue
Head & Neck, 2015
Background. Lymph node density (LND) is more useful than the TNM classification in predicting survival after surgery for many cancers. The purpose of this study was to clarify independent prognostic factors for hypopharyngeal squamous cell carcinoma (HPSCC) and broaden the staging system to improve its predictive value. Methods. The present study included 105 patients with HPSCC treated with hypophagectomy and neck dissection between 1993 and 2014. Results. The median LND in patients with HPSCC was 0.060 (range 0.026-0.620). We found a significant difference in LND values between patients with and without recurrence (0.063 vs. 0.030, respectively; p = 0.001). The cutoff value of LND for recurrence was 0.055, with a sensitivity of 68% and specificity of 71%. Cervical lymph node metastasis, advanced pathologic T stage, lymphovascular invasion, LND C0.055, and extracapsular spread had significant adverse effects on 5-year overall and disease-specific survival in a univariate analysis. Multivariate analysis confirmed a significant association between 5-year overall survival and LND C0.055 [hazard ratio (HR) 2.19; 95% confidence interval (CI) 1.06-4.51; p = 0.035] and extracapsular spread (HR 2.47; 95% CI 1.09-5.61; p = 0.030). Furthermore, LND C0.055 (HR 2.30; 95% CI 1.07-4.93; p = 0.034) and extracapsular spread (HR 2.95; 95% CI 1.20-7.29; p = 0.019) were associated with 5year, disease-specific survival. Conclusions. The median LND cutoff values C0.055 are associated with a greater risk of recurrence and survival in patients with HPSCC.
Histopathologic prognostic indices in tongue squamous cell carcinoma
European Archives of Oto-Rhino-Laryngology, 2020
Purpose Consistent prognosticators are needed to guide adjuvant treatment in tongue squamous cell carcinoma (SCC). We validate the prognostic significance of histopathologic parameters in surgically treated tongue SCC. Methods Archival specimens of 88 consecutive patients who were treated surgically for tongue SCC from 2003 to 2016 were re-analyzed by one pathologist. Patient records were retrospectively reviewed. Prognosticators of recurrence-free survival (RFS), overall survival (OS), and disease-specific survival (DSS) were identified using multivariate analysis. Results Tumor depth of invasion (DOI) > 6 mm (OR 4.76; 95%CI 1.22-18.5; p = 0.024) and lymphovascular invasion (OR 5.61; 95%CI 1.00-31.5; p = 0.05) were independent predictors of nodal metastases. The overall 5-year RFS, OS and DSS were 70%, 82% and 84% respectively. Positive margins predicted poor RFS (HR 3.91; 95%CI 1.58-9.65; p = 0.003) and local recurrence-free survival (HR 4.96; 95%CI 1.36-18; p = 0.015). Presence of nodal metastases (HR 5.03; 95%CI 1.73-14.6; p = 0.003), tumor DOI > 6 mm (HR 9.91; 95%CI 1.26-78.0; p = 0.029) and positive margins (HR 8.26; 95%CI 2.75-24.8; p < 0.001) were independent predictors of poor OS. Presence of nodal metastases (HR 3.87; 95%CI 1.17-12.8; p = 0.027) and positive margins (HR 12.3; 95%CI 3.54-42.9; p < 0.001) also independently predicted poor DSS. Conclusion Margins' status was the only independent predictor of local recurrence. Tumor DOI, nodal and margin status were key prognosticators of survival and may determine the necessity for adjuvant therapy.

One of the main changes in the 8th edition of the American Joint Committee on Cancer (AJCC) for staging of oral cancer is the inclusion of depth of invasion (DOI) in the T-category. However, cancers in different oral subsites have variable behavior, with oral tongue squamous cell carcinoma (OTSCC) being the most aggressive one even at early stage. Thus, it is necessary to evaluate the performance of this new T-category in homogenous cohort of early OTSCC. Therefore, we analyzed a large cohort of patients with a small (≤ 4cm) OTSCC to demonstrate the differences in T-stage between the AJCC 7th and 8th editions. A total of 311 early-stage cases (AJCC 7th) of OTSCC were analyzed. We used 5mm and 10mm DOI for upstaging from T1 to T2 and from T2 to T3 respectively, as in the AJCC 8th. We further reclassified the cases according to our own proposal suggesting 2mm to upstage to T2 and 4mm to upstage to T3. According to AJCC 7th, there were no significant differences in the survival analysis. When we applied the 8thedition, many cases were upstaged to T3 and thus associated with worse disease-specific survival (HR 2.37, 95%CI 1.12-4.99) and disease-free survival (HR 2.12, 95%CI 1.09-4.08). Based on our proposal, T3 cases associated with even worse disease-specific survival (HR 4.19, 95%CI 2.27-7.74). The 8th edition provides better survival prediction for OTSCC than the 7th, and can be further optimized by lowering the DOI cutoffs.

The objective was to evaluate the association of the immunoexpression of cancer stem cell (CSC) markers with clinicopathological and survival outcomes in tongue squamous cell carcinoma (TSCC) patients. This systematic review and meta-analysis [PROSPERO (CRD42021226791)] included observational studies that compared the association of clinicopathological and survival outcomes with CSC immunoexpression in TSCC patients. Pooled odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CI) were used as outcome measures. Six studies identified the association with three surface markers (c-MET, STAT3, CD44) and four transcription markers (NANOG, OCT4, BMI, SOX2). The odds of early-stage presentation were 41% (OR = 0.59, 95% CI 0.42–0.83) and 75% (OR = 0.25; 95% CI 0.14–0.45) lower in CSC and SOX2 immuno-positive cases than immuno-negative cases, respectively. The odds of well-differentiated tumors in transcription marker immuno-positive cases were 45% lower compared to immuno-negative cases (OR = 0.55, 95% CI 0.32–0.96). The odds of positive lymph nodes were 2.01 times higher in CSC immuno-positive cases compared to immuno-negative cases (OR = 2.01, 95% CI 1.11–3.65). Mortality in immuno-positive cases was 121% higher than that in immuno-negative cases (HR = 2.21; 95% CI 1.16–4.21). Advanced tumor staging and grading, lymph node metastasis, and mortality were significantly associated with positive immunoexpression of CSC markers.
Tumor lymphangiogenesis in head and neck squamous cell carcinoma
Cancer, 2004
BACKGROUND. Tumor metastasis to regional lymph nodes via the lymphatic system represents the first step of dissemination in head and neck squamous cell carcinoma (HNSCC) and serves as a major prognostic indicator for disease progression and as a guide for therapeutic strategies. In the current study, the authors investigated whether tumor lymphangiogenesis may be related to the risk of lymph node metastasis and to clinical outcome in patients with HNSCC.

Background: Tongue tumors show intra and inter-tumoral heterogenicity with high incidence, relapse and mortality rates necessitating further research. Recurrence/metastasis that occurs after surgical resection of primary cancer is often the reason for poor survival in these patients. Lymph nodes are the most common site of metastasis in tongue tumors. Therefore, premetastatic molecular changes can be best evaluated in lymph nodes which may epitomize the earliest events in the metastasis cascades. The presence of circulating tumor cells(CTCs) in the absence of nodal disease (N0) may represent tumor aggressiveness, suggesting an immune escape which may have high metastatic potential. This trial was developed to investigate the earliest pre-metastatic changes which may regulate tumor dormancy and predict metastasis. A better understanding of organotropism or pre-metastatic changes can help in theragnostic, thereby preventing the outbreak of overt metastasis. Methods: A single-institutional prospective observational cohort study. This trial will be conducted at a tertiary care Centre (Amrita Institute of Medical Sciences Kochi). Eligible patients will be enrolled after obtaining informed consent. The dissected lymph nodes will be subjected to histopathological and immunohistochemical analyses for premetastatic niche (PMN) formation. In addition, circulating tumor cells will be evaluated before treatment and 6 months after treatment. The patients will be followed up for a period of two years to correlate the findings with the recurrence-free survival. Expected results: The pre-metastatic changes, if detected will be a predictive biomarker. It may help to define future drug targets for metastasis chemoprevention. CTCs may define the tumor aggressiveness ,there by prognostication and helps in better disease
Cervical lymph node metastasis from early-stage squamous cell carcinoma of the oral tongue
Acta Oto-laryngologica, 2013
Conclusions: The findings of this study demonstrated that the wait-and-watch strategy for neck metastasis from squamous cell carcinoma (SCC) of oral tongue is a reliable option and that salvage by surgical treatment is effective. However, younger patients should be closely monitored for recurrence. Adjuvant therapy may be recommended for patients with pathologically advanced disease. Objectives: Metastatic involvement of cervical lymph nodes is the most important prognostic indicator in patients with oral tongue SCC. With the objective of determining the most appropriate treatment strategy for regional recurrence, we conducted a retrospective review of clinicopathologic factors. Methods: The clinicopathologic features of 103 patients with oral tongue SCC, in whom the local lesions were treated successfully by low-dose interstitial brachytherapy (LD-IBT), but who subsequently developed cervical lymph node metastases and were treated by salvage surgery, were reviewed. Results: In the patients who underwent surgical treatment at our hospital, 5-year disease-free survival and regional control rates were 69.3% and 85.3%, respectively. The clinicopathologic factors significantly associated with unfavorable disease-free survival were the presence of extracapsular spread (hazard ratio (HR) = 3.005, p = 0.045), multiple and large lymph nodes (HR = 2.850, p = 0.010 and HR = 3.112, p = 0.007, respectively), younger age (HR = 2.429, p = 0.048), and shorter interval from the LD-IBT to detection of neck metastasis (HR = 1.749, p = 0.013).

Objective: To find useful markers for predicting late cervical metastasis in patients with N0 squamous cell carcinoma of the tongue. Patients and Methods: The clinicopathological features of 57 consecutive patients with previously untreated N0 squamous cell carcinoma of the tongue were reviewed. Thirty patients had T1 disease, 20 had T2 disease, and 7 had T3 disease. All patients were treated with partial glossectomy without elective neck dissection. Clinicopathological factors were analysed to determine the factors predicting late cervical lymph node metastasis. Results: The overall cervical lymph node metastasis rate was 19.3%. The clinicopathologic factors significantly associated with the development of cervical lymph node metastasis were tumour size (30 mm), tumour depth (4 mm), differentiation (moderate), mode of invasion (G4C, 4D), microvascular invasion (present), muscle invasion (present), and invasive front grading (12 points). In a multivariate logistic regression analysis, invasive front grading ≥12 points in squamous cell carcinoma of the tongue with a tumour depth ≥4 mm had predictive value for late cervical lymph node metastasis.

90% of the tumors in the head and neck are squamous-cell carcinomas (HNSCC), which have overall 5- year survival rate between 50% -60%. CD44 has been shown to be associated with the prognosis. Biopsy specimens of 51 patients with oral tongue SCC were evaluated by Immunohistochemistry (IHC) for the CD44 antibody. There was no significant correlation between CD44 and survival (P=0.77), age (P=0.4), CD44 and lymph node metastasis (P=0.87), sex (P=0.947), smoking (P=0.287) and tumor size (P=0.813). However, there was significant correlation between smoking and survival. There are widespread discrepancies among the findings in the literature regarding the prognosis of CD44 expression in OCSCC. Our study shows that the expression of CD44 is not a marker of aggressive behavior in oral tongue SCC. Consequently, CD44 cannot be considered as handy tool to establish the tumor behavior, prognosis and 5- year survival rate of these tumors.
