Correlation of Bcl-2 Expression with Prognosis and Survival in Patients with Head and Neck Cancer: A Systematic Review and Meta-Analysis. Crit Rev Oncol Hematol 2023:104021. [PMID: 37210016 DOI: 10.1016/j.critrevonc.2023.104021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 04/27/2023] [Accepted: 05/08/2023] [Indexed: 05/22/2023] Open
Abstract
Head and neck cancer (HNC) is a growing disease, affecting more than 700.000 cases per year and ranking as the sixth most prevalent type of cancer worldwide. The impossibility of properly entering into apoptosis directly influences uncontrolled growth and consequently tumor development and progression. Bcl-2 emerged as a key regulator in the balance between cell apoptosis and proliferation in apoptosis machinery. This systematic review and meta-analysis aimed to review all published studies investigating changes in Bcl-2 protein expression assessed by immunohistochemistry (IHC) and related to prognostic and survival values of patients with HNC. After applying the inclusion and exclusion factors, we reached the number of 20 articles included in the meta-analysis. The random-effect pooled HR (CI95%) value of OS related to Bcl-2 IHC expression in tissues from HNC patients was 1.80 (CI95% 1.21-2.67) (p < 0.0001) and DFS was 1.90 (CI95% 1.26-2.86 (p < 0.0001). The OS value for the specific oral cavity tumors was 1.89 (1.34-2.67), while in the larynx it was 1.77 (0.62-5.06), and the DFS in the pharynx was 2.02 (1.46-2.79). The univariate and multivariate analyses of OS were respectively 1.43 (1.11-1.86) and 1.88 (1.12-3.16), while in DFS it was 1.70 (0.95-3.03) and 2.08 (1.55-2.80). The OS considering a low cut-off for Bcl-2 positivity was 1.19 (0.60-2.37) and DFS was 1.48 (0.91-2.41), while studies with a high cut-off demonstrated OS of 2.28 (1.47-3.52) and DFS of 2.77 (1.74-4.40). Our meta-analysis demonstrates that Bcl-2 protein overexpression can result in worse LNM, OS, and DFS in patients with HNC, however, it is not a reliable conclusion, due to the wide divergences between the original studies and the fact that many studies have a very high range of confidence and also a high risk of bias.

Abstract
Laryngeal carcinoma is the second common malignancy of the upper aerodigestive tract after lung cancer; in most cases is a squamous cell carcinoma, whose risk factors include tobacco smoking and alcohol consumption. Despite therapeutic progress, the five-year overall survival rate for this malignancy has remained nearly 50% and many patients already present metastasis at the time of diagnosis. To date, there are no tools that predict the evolution of laryngeal carcinoma: in this light, during the last years, many studies were planned with the aim to investigate the role played by different biomarkers expressed by larynx cancer, which can help make an early diagnosis, predict disease evolution and direct therapeutic choice. This review aims to summarize these markers and correlating them with disease evolution.

Abstract
OBJECTIVE: We sought to study various parameters in laryngeal squamous cell carcinoma (LSCC) that might predict nodal metastasis. STUDY DESIGN AND SETTING: Sixty-four LSCCs were examined with respect to their histopathology and, using immunohistochemistry, their proliferative capacity (MIB1), p53 and cyclin D1 status, and intratumoral microvessel density. The presence of human papillomavirus was ascertained by the polymerase chain reaction. RESULTS: Histopathologically, most tumors had an infiltrating/mixed growth pattern and a diminished inflammatory reaction at the growing margin. In addition, 56% of the tumors were positive for MIB1, with 64% showing p53 overexpression; 70% were positive for cyclin D1; and 59% showed increased tumor microvessel density. Of 42 cases analyzed, 9.5% were positive for human papillomavirus 16. CONCLUSIONS: Of the parameters studied, a diminished lymphocytic inflammatory response at the periphery ( P < 0.05) and cyclin D1 overexpression ( P < 0.001) correlated significantly with cervical nodal metastasis at presentation. SIGNIFICANCE: Cyclin D1 overexpression, easily assessed on biopsy samples, may thus help in optimizing therapy at the outset.

Prognostic value of Bcl-2 expression in squamous cell carcinoma of the larynx: a systematic review. Int J Biol Markers 2015; 30:e155-60.

Abstract
The aim of this systematic review was to determine the prognostic value of Bcl-2 immunostaining in patients affected by laryngeal squamous cell carcinoma. An appropriate search was conducted on PubMed to retrieve articles dealing with this topic. A double cross-check was performed on citations and full-text articles by 2 investigators independently to review all manuscripts and perform a comprehensive quality assessment. Of 115 abstracts identified, 15 articles were included. These studies reported on 1,150 patients with histologically confirmed diagnosis of laryngeal squamous cell carcinoma. Only a few studies showed a statistical correlation between Bcl-2 immunohistochemical expression and at least 1 of the clinical and histopathological parameters considered by the authors. Moreover, these findings were also discordant between them. Overall the studies analyzed suggested that Bcl-2 expression was statistically connected with N stage (2/14), grading (2/14), disease-free survival (3/14) and overall survival (5/14). Interestingly, all of the 3 studies investigating the relation between Bcl-2 and radioresistance showed significant results in terms of recurrence-free survival and overall survival. Our review strongly suggests that the immunohistochemical staining of Bcl-2 does not correlate with tumoral aggressiveness and prognosis of patients affected by laryngeal squamous cell carcinoma and treated with primary surgery. However, an interesting connection of this protein could be demonstrated with tumoral radioresistance. Further, high-quality prospective studies should be carried out to confirm this hypothesis.

Abstract
Despite their histological resemblance to colorectal adenocarcinoma, there is little information on the molecular events involved in the pathogenesis of intestinal-type sinonasal adenocarcinoma (ITACs). The aim of this paper is to evaluate the possible role of TP53 and Bcl-2 gene defects in ITAC by investigating the immunohistochemical expression of TP53 and Bcl-2 gene products in a group of ethmoidal ITACs associated with occupational exposure. A retrospective study on 15 patients with pathological diagnosis of primary ethmoidal ITAC was conducted. Representative formalin-fixed, paraffin wax-embedded block from each case was selected for immunohistochemical studies using the antibodies against p53 and Bcl-2. Clinical-pathological data were also correlated with the staining results. The results of immunohistochemical examination demonstrated that poorly differentiated cases showed a higher percentage of p53 and Bcl-2 expressing cells in comparison to well-differentiated cases. No correlation was found with other clinico-pathological parameters, including T, stage and relapses. The relationship between up-regulation of p53 and Bcl-2 and poorly differentiated ethmoidal adenocarcinoma suggests a role of these genes, in combination with additional genetic events, in the pathogenesis of ITAC.

Abstract
OBJECTIVES To summarize existing evidence about whether the presence of mutant or upregulated p53 is a prognostic factor for patients presenting with squamous cell carcinoma arising from the larynx, oropharynx, hypopharynx, or oral cavity. METHOD Relevant articles were identified using strict criteria for systematic searches. Associations between mutant or upregulated p53 versus wild-type or low/undetectable p53 in relation to overall survival and DFS were summarized by extracting or deriving hazard ratio (HR) estimates. Random-effects meta-analyses were used to account for between-study heterogeneity and to summarize the effect of p53 across studies. RESULTS The meta-analyses gave a statistically significant pooled HR for overall survival in oral cavity [pooled HR, 1.48; 95% confidence interval, (95% CI), 1.03-2.11], and for disease-free survival in oral cavity (pooled HR, 1.47; 95% CI, 1.12-1.93) and in oropharynx (pooled HR, 0.45; 95% CI, 0.27-0.73). Despite attempts to limit it, between-study heterogeneity was large in the majority of meta-analyses and the prognostic value of p53 was generally inconsistent and inconclusive across studies. CONCLUSION The meta-analysis results highlight that current evidence about the prognostic value of p53 in patients with squamous cell carcinoma of the head and neck is inconclusive. Large heterogeneity exists across studies in study-level and patient-level characteristics, making it difficult to ascertain a clear picture. Future studies are required in which p53 expression is investigated in a more standardized and biologically informative manner. In particular, prospectively planned individual patient data meta-analyses are needed to establish the prognostic importance of p53 for specific subgroups of patients undergoing specific treatments.

Abstract
Human papillomavirus is involved in the carcinogenesis of tonsillar squamous cell carcinomas. Here, we investigated the expression and the prognostic value of key cell cycle proteins in the pRb and p53 pathways in both human papillomavirus type 16-positive and -negative tonsillar squamous cell carcinomas. Using immunohistochemistry, 77 tonsillar squamous cell carcinomas with known human papillomavirus type 16 status and clinical outcome were analyzed for expression of Ki67, p16(INK4A,) cyclin D1, pRb, p14(ARF), MDM2, p53, p21(Cip1/WAF1), and p27(KIP1). Results were correlated with each other and with clinical and demographic patient data. A total of 35% of tonsillar carcinomas harbored integrated human papillomavirus type 16 DNA and p16(INK4A) overexpression, both being considered essential features for human papillomavirus association. These tumors also showed the overexpression of p14(ARF) (P<0.0001) and p21(Cip1/WAF1) (P=0.001), and downregulation of pRb (P<0.0001) and cyclin D1 (P=0.027) compared with the human papillomavirus-negative cases. Univariate Cox regression analyses revealed a favorable survival rate for non-smokers (P=0.006), as well as for patients with T1-2 tumors (P<0.0001) or tumors showing low expression of cyclin D1 (P=0.028), presence of human papillomavirus and overexpression of p16(INK4A) (P=0.01), p14(ARF) (P=0.02) or p21(Cip1/WAF1) (P=0.004). In multivariate regression analyses, smoking and tumor size, as well as expression of cyclin D1 and p21(Cip1/WAF1), were found to be independent prognostic markers. We conclude that human papillomavirus positivity in tonsillar squamous cell carcinomas strongly correlates with p21(Cip1/WAF1) and p14(ARF) overexpression and downregulation of pRb and cyclin D1. In particular p21(Cip1/WAF1) overexpression is an excellent favorable prognosticator in tonsillar squamous cell carcinomas.

Abstract
The carcinogenesis of human papillomaviruses type 16 (HPV-16) is mainly due to its two oncoproteins, E6 and E7. Their carcinogenic features in term of their relationship with Bcl-2 family are still unclear. We thus aimed to analyze the expression of Bcl-2 family members, Bcl-2, Bax, and Bak in laryngeal cancer cells transfected with the E6 or E7 and to determine the sensitivity of these cells to apoptotic stimuli. We employed two human laryngeal cancer cell lines, UMSCC12 and UMSCC11A in this study. These two cell lines were stably transfected with HPV16 E6, E7 or empty vector, pcDNA3.1. We found that E6 and E7 inhibited apoptosis induced by TNF-alpha/CHX in both UMSCC11A and UMSCC12 cells, enhanced the stability of Bcl-2 protein and increased the degradation of Bak protein. Furthermore, it was found that HPV-16 E7 statistically enhanced the expression of Bcl-2 in laryngeal cancer. The alteration of Bak by E6 and E7 was not through the influence on the Bak promoter, as the luciferase assay showed that neither E6 nor E7 changed the Bak promoter activity. We conclude that the evasion of apoptosis mediated by HPV-16 E6 and E7 is associated with increased Bcl-2 and decreased Bak in laryngeal carcinogenesis and that the decreased level of Bak by E6 and E7 is not caused by the regulation of the Bak promoter but by reducing its protein stability.

Abstract
OBJECTIVE To assess tumor markers in advanced laryngeal cancer. DESIGN Marker expression and clinical outcome. PATIENTS Pretreatment tumor biopsy specimens were analyzed from patients enrolled in the Department of Veterans Affairs Laryngeal Cancer Study. MAIN OUTCOME MEASURES Expression of p53 (OMIM TP53) and Bcl-xL (OMIM 600039) in pretreatment biopsy specimens was assessed for correlation with chemotherapy response, laryngeal preservation, and survival. RESULTS Higher rates of larynx preservation were observed in patients whose tumors expressed p53 vs those that did not (80% [36 of 45 patients] vs 59% [24 of 41 patients], P =.03). Higher rates of larynx preservation were also observed in patients whose tumors expressed low levels of Bcl-xL vs high levels of Bcl-xL (90% [18 of 20 patients] vs 60% [30 of 50 patients], P =.02). Patients were categorized into 3 risk groups (low, intermediate, and high) based on their tumor p53 and Bcl-xL expression status. Patients whose tumors had the high-risk biomarker profile (low p53 expression and high Bcl-xL expression) were less likely to preserve their larynx than patients whose tumors had the intermediate-risk biomarker profile (high p53 expression and low or high Bcl-xL expression) or the low-risk biomarker profile (low p53 expression and low Bcl-xL expression). The larynx preservation rates were 100% (10 of 10 patients), 77% (26 of 34 patients), and 54% (7 of 13 patients) for the low-risk, intermediate-risk, and high-risk groups, respectively (P =.04, Fisher exact test). CONCLUSION Tumor expression of p53 and Bcl-xL is a strong predictor of successful larynx preservation in patients treated with induction chemotherapy and followed by radiation therapy in responding tumors.

Abstract
Background Very few reports have investigated the role of cell cycle regulators as biomarkers in Basaloid Squamous Cell Carcinoma (BSCC) of the larynx, a definite morphologic, uncommon, very aggressive variant of squamous cell carcinoma. Lower expression of Ki67/Mib-1, a proliferation marker highly expressed in the majority of tumours, and p53, a tumour suppressor protein that can induce an arrest of the G1-S transition, was related to a better prognosis in laryngeal BSCC. In the head and neck, p27kip1, a member of the Cip1/Kip1 family of cyclin-dependent kinase inhibitors, has emerged as an independent prognostic factor, able to identify low-expressing tumours with unfavourable course. Up to date the role of this protein was never studied in BSCC. Aim of our study was to investigate the potential prognostic value of p27kip1 levels and their correlation with Ki67/Mib-1 and p53 expression in BSCC of the larynx. Methods The retrospective study group consisted of 15 male and 1 female patients, affected by laryngeal BSCC, ranging in age from 44 to 69 years (mean 58). The tumour originated from the supraglottis in thirtheen cases and from the glottis in the remaining three. Ten patients had metastatic cervical lymph nodes at presentation and were classified as N+. Post surgical stage was IV in four patients, III in nine, II in two cases and I in the remaining one. Follow-up ranged from a minimum of 5 months up to 9 years. Paraffin-embedded tissue sections of each laryngeal tumour were analyzed for p27kip, Ki67/Mib-1 and p53 expression by immunohistochemistry. Results The immunohistochemical study showed p27kip1 expression in 40% of the patients with no evidence of disease (NED) and in none (0%) of the patients dead of disease (DOD), whilst p53 was expressed in 60% of patients in NED status and in 90% of patients in DOD status. Ki67/Mib-1 was positive in 80% of NED patients and in 100% of DOD patients. At multivariate analysis, performed by means of Discriminant analysis, low levels of p27kip1 expression significantly correlated with poor prognosis (P < 0.05). Conclusion p27kip1 protein has been shown to be a significant independent prognostic factor in laryngeal SCC. In our series of laryngeal BSCC the resulting data seem to confirm the clinical prognostic relevance of p27kip1 low expression, which directly correlated with biological aggressiveness and consequent shortened survival.

Abstract
Head and neck squamous cell carcinoma (HNSCC) involves the upper aerodigestive tract and can destroy the structure and function of organs involved in voice, speech, taste, smell and hearing, as well as vital structures necessary for survival. HNSCC has long been a treatment challenge because of the high rate of recurrences and of advanced disease at the time of diagnosis. Molecular identification of tissue biomarkers in diagnostic biopsy specimens may not only identify patients at risk for developing HNSCC but may also select patients that may benefit from more aggressive treatment modalities. Several biomarkers studied to date such as the proteins p53, cyclin D1, p16, Cox-2 enzyme, epidermal growth factor and vascular endothelial growth factor receptors, matrix metalloproteinases and the Fhit marker for genomic instability could be manipulated for the therapeutic benefit of these patients. This review presents the most updated information on molecular biomarkers with the greatest prognostic potential in HNSCC and discusses some factors that contribute to the controversy concerning their prognostic importance.

Abstract
Bcl-2 and clusterin genes have been related to the inhibition of apoptosis, an event that plays a key role in malignant transformation and in invasive disease. In this work, we determine the significance of clusterin and bcl-2 expression in a large series of laryngeal carcinomas. We used immunohistochemical methods and in situ hybridization to examine the expression of these proteins. Nontumoral epithelial laryngeal tissues did not express clusterin and bcl-2 proteins. However, 9% (14 out of 154) and 25% of these tumors (39 of 154) had positive clusterin and bcl-2 staining, respectively. Clusterin expression was significantly related to the degree of local invasion and higher bcl-2 expression was found in these clusterin-positive tumors (p < 0.05). Bcl-2 expression was significantly correlated with supraglottic localization, nodal metastases, invasion in depth, and poorly differentiated tumors. However, by multivariate analysis, bcl-2 was shown to be an independent predictor of good prognosis in these tumors (OR = 0.12, 95% CI = 0.02-0.91). These findings indicate that clusterin and bcl-2 are upregulated in laryngeal carcinomas and their expression is related to the invasiveness of these tumors.

Abstract
BACKGROUND Although many histopathologic characteristics of oral squamous cell carcinoma (O-SCC) have been identified as prognostic factors, accurate, and unequivocal factors have not been clearly identified. The purpose of this study was to evaluate a potential association between the histologic grade of malignancy at the deep invasive front and the expression of Ki-67 antigen and p53 protein in O-SCC. METHODS The expression of Ki-67 antigen and p53 at the invasive tumor front area of O-SCC was examined by immunohistochemistry of archived tissue from 62 cases. The mean age of patients was 60.7 years (range: 37-89) and the male-female ratio was 1.6:1 (38 men, 24 women). There were 20, 17, 14, and 11 cases classified as stage I to stage IV, respectively. The correlation between the intensity of immunostaining for Ki-67 antigen and p53 and the histologic grade of malignancy at the deep invasive front (invasive front grade, IFG) was analyzed. The expression of Ki-67 antigen and p53 in normal oral epithelia (10 cases) was also investigated. RESULTS The mean Ki-67 labeling index (LI) in the O-SCC samples was 32.8 +/- 12.0% (n = 62). The mean total score of IFG (IFG score) was 9.1 +/- 2.7 points (n = 62). There was a significant linear correlation between the IFG score and the Ki-67 antigen (gamma = 0.651, R2 = 0.596, P < 0.0001). Of 50 tumors examined, 27 (54.0%) exhibited p53-positive nuclear immunostaining. The staining patterns for Ki-67 antigen and p53 were similar. Both Ki-67-LI and p53-positive status were significantly correlated with the IFG scores. CONCLUSION The findings of this study demonstrate that overexpression of Ki-67 antigen and p53 at the deep tumor invasive front of O-SCC is associated with histologic grade of malignancy.

Abstract
BACKGROUND Nonreported and selectively reported information and the use of different definitions may introduce biases in the literature of prognostic factors. We probed these biases in a meta-analysis of a prognostic factor for head and neck squamous cell cancer (HNSCC) mortality that has drawn wide attention--the status of the tumor suppressor protein TP53. METHODS We compared results of meta-analyses that included published data plus unpublished data retrieved from investigators; published data; and only published data indexed with "survival" or "mortality" in MEDLINE/EMBASE, with or without standardized definitions. We also evaluated whether previously published meta-analyses on mortality predictors for various malignancies addressed issues of retrieval and standardized information. All statistical tests were two-sided. RESULTS For the 18 studies with 1364 patients that included published and indexed data, we obtained a highly statistically significant association between TP53 status and mortality. When we used the definitions preferred by each publication, the association was stronger (risk ratio [RR] = 1.38, 95% confidence interval [CI] = 1.13 to 1.67; P = .001) than when we standardized definitions (RR = 1.27, 95% CI = 1.06 to 1.53; P = .011). The addition of 13 studies with 1028 subjects that included published but not indexed data reduced the observed association (RR = 1.23, 95% CI = 1.03 to 1.47; P = .02). Finally, when we obtained data from investigators (11 studies with 996 patients) and analyzed it with all other data, statistical significance was lost (RR = 1.16, 95% CI = 0.99 to 1.35; P = .06). Among 18 published meta-analyses of 37 cancer prognostic factors, 13 (72%) did not use standardized definitions and 16 (89%) did not retrieve additional information. CONCLUSIONS Selective reporting may spuriously inflate the importance of postulated prognostic factors for various malignancies. We recommend that meta-analyses thereof should maximize retrieval of information and standardize definitions.

Abstract
BACKGROUND Chemical carcinogens induce squamous cell carcinoma (SCC) of the head and neck by targeting the p53 and the retinoblastoma (pRb) pathways. Human papillomavirus (HPV) might have an etiologic role in these cancers at particular sites. Few studies have compared cell cycle protein expression in HPV-positive and HPV-negative tumors in this region. METHODS Fifty tonsil SCCs were analyzed for HPV by PCR and for expression of cell cycle proteins (p53, pRb, p16(INK4A), p21(CIP1/WAF1), p27(KIP1), and cyclinD1) by immunohistochemistry. RESULTS HPV was present in 42%; almost all were type 16. There were statistical associations between HPV positivity and reduced expression of pRb and cyclinD1, overexpression of p16, and younger patient age. Tumor with down-regulated p27 tended to have down-regulated pRb and p21. CONCLUSIONS HPV-positive tonsil SCCs have distinct molecular pathways. Their association with younger patient age suggests that they are biologically distinct from HPV-negative tumors.

Abstract
BACKGROUND Aberrations of the p53 gene and overexpression of its protein are widely recognized markers of malignancy including oral squamous cell carcinomas. This study was performed to evaluate the relationship of immunoexpression of p53 protein in series of 91 squamous cell carcinomas of the oral cavity with clinicopathologic parameters and to investigate whether p53 immunoexpression might influence the clinical outcome of the disease. METHODS From a group of 287 consecutive patients, 91 surgically treated ones were randomly selected. P53 protein expression was investigated by means of immunohistochemistry. Clinical and histopathologic data were gathered, and the patient survival was analyzed. RESULTS Of the oral carcinomas, 52.7% (n = 48) overexpressed p53, using a threshold of 10% stained cell nuclei. There was a negative correlation of p53 immunoexpression with a histologic grade of differentiation (r = -0.236, p =.06) but not with clinical variables. Overall survival rate was 59% at 5 years. In univariate analysis, tumor size, node status, and advanced clinical stage were significantly associated with shortened overall survival. In patients without neck node metastases, p53 showed a strong correlation with survival (p =.01). In multivariate analysis performed only on N0 patients, tumor extension and p53 immunoexpression were found to be the only independent prognostic parameters with relative risks of 1.9 and 4.3, respectively. CONCLUSIONS A strong relationship was observed between p53 immunoexpression and poor prognosis in patients with oral squamous cell carcinomas without neck node metastases.

Abstract
Human papillomavirus type 16 (HPV 16) plays an etiological role in human laryngeal carcinoma. Apoptosis is closely associated with various biological processes including oncogenesis. This study investigated how HPV 16 oncoproteins E6 and E7 affect apoptosis in human laryngeal cancer cells. We established two human laryngeal cancer cell lines that expressed HPV 16 E6 and E7, respectively. Using these two cell lines, we found that both E6 and E7 exhibited an inhibitive effect on apoptosis induced by tumor necrosis factor alpha and cycloheximide. In both transfected cell lines, the expression of pro-apoptotic Bak was reduced and that of anti-apoptotic Bcl-2 was over-expressed. However, the expression of caspase-3 and caspase-8 was not significantly different between the E6- and E7-transfected cells and the control cells without HPV 16. p53 Protein was not detected in either the transfected or the non-transfected cells. Our study indicates that: (1) HPV 16 E6 and E7 oncoproteins are capable of inhibiting apoptosis in laryngeal squamous carcinoma cells; (2) the mechanism modulated by E6 and E7 involves the over-expression of Bcl-2 and the down-regulation of Bak; (3) the anti-apoptotic pathway is not related to the level of p53, caspase-3, or caspase-8. These results suggest that the dysregulation of apoptotic molecules Bak and Bcl-2 by HPV 16 E6 and E7 plays a role in the prolongation of cell survival, which may subsequently contribute to the development of human laryngeal cancer.

Abstract
Even though the roles of different known or suggested prognostic factors in laryngeal cancer have been studied in detail, clinical stage at time of diagnosis and anatomic subsite of the tumour remain the only practical predictors of clinical outcome and offer the only guidelines in the planning of treatment. In this study, the relative roles of known demographic and clinical prognostic factors, in addition to four histopathological factors, were evaluated in a sample of 100 laryngeal carcinoma patients with multivariate analysis using the Cox regression model. In addition to advanced stage (stage III-IV) (relative hazard of death (HR) 8.9, p=0.01) and supraglottic disease (HR 5.6, p=0.02), high apoptotic index (HR 11.1, p=0.05) was significantly associated with poor survival. Cell proliferation, p53 and angiogenesis did not significantly affect the prognosis. In the future, high degree of apoptosis could be used to identify patients with poor prognosis in laryngeal cancer.

Abstract
Molecular prognostic and predictive factors have extensively been studied in different cancers during the past decades, some of which were found to be useful in diagnosis, follow up or even treatment of some malignant tumors. To assess the significance of c-erbB-1, c-erbB-2 and p53 expression in head and neck tumors among Iranian patients and their correlation with known prognostic factors, samples from 53 patients with squamous cell carcinomas of larynx and tongue were studied immunohistochemically. Strong immunoreactivity of c-erbB-1, c-erbB-2 and p53 was observed in 37 (70%), 40 (76%) and 37 (70%) of cases, respectively. The coexpression of these molecules was detected in 27 (50.9%) samples. Neither histological grading nor nodal involvement revealed correlation with c-erbB-1 and/or c-erbB-2 expression. No correlation was found between p53 expression and histological grade. However, a significant positive association was observed between p53 expression and nodal involvement. This data, which is the first report on head and neck squamous cell carcinomas (HNSCC) in Iran, indicates the significance of p53 protein expression which may result from p53 tumor suppressor gene inactivation in lymph node metastasis of HNSCC among Iranian patients.
