A Low Systemic Inflammatory Response Index Is Associated With Improved Survival in Adenoid Cystic Carcinoma Patients

BackgroundPredicting the long-term survival in adenoid cystic carcinoma(ACC) patients remains is challenging. Inflammatory cell-based indices are emerging as prognostic indicators of oncology. PurposeThis study aimed to determine the associations between the preoperative systemic inflammatory response index (SIRI) and, systemic immunoinflammatory index (SII), and the 10-year survival rates in patients with ACC of the head and neck (ACCHN). Study Design, Setting, SampleThis retrospective cohort study comprised ACCHNN patients treated at the Chinese People's Liberation Army General Hospital between November 2003 and December 2020. Predictor VariableThe inflammatory response, assessed using the SIRI and SII, was the predictor variable, The optimal cut-off values were based on the maximum Youden index values (sensitivity ＋ specificity－1), The patients were divided into two-group each, based on the SIRI (low, ≤ 0.15) and (high, > 0.15), and SII (low, ≤ 562.8 and high, > 562.8) values. Outcome VariableOverall survival (OS), or the number of days, weeks, or months between treatment initiation and death (or last follow-up date), was the primary outcome variable. CovariatesThe covariates were classified as demographic (age, gender, body mass index), medical (hypertension, diabetes), inflammatory (neutrophils, lymphocytes, monocytes, platelets, lymphocyte-monocyte ratio, platelet-lymphocyte ratio, neutrophil-lymphocyte ratio), and perioperative (tumor stage, lymph node metastasis, tumor size, treatment type). AnalysesDescriptive, univariate, and multivariate Cox proportional risk regression analyses were performed to determine whether the SIRI and SII were independent prognostic factors for OS. Kaplan–Meier survival curves and log-rank tests were used to determine their associations with the OS. ResultsThe study sample comprised 162 patients (mean age, 52 ± 14; males, 39.5%). The median follow-up time was 6.81 ± 0.23, and the 10-year OS rate was 7.68 ± 0.25. The low and high SIRI groups comprised 109 and 53 patients, while the low and high SII groups comprised 116 and 46 patients, respectively. SIRI was identified as a prognostic factor (P < 0.01; hazard ratio, 2.45; 95% confidence interval, 1.35–4.45). Conclusion and RelevanceThe SIRI has the advantages of reproducibility, convenience, non-invasiveness, and affordability, making it a promising prognostic inflammatory index for patients with ACCHN.

Exploration of High-Grade Transformation and Postoperative Radiotherapy on Prognostic Analysis for Primary Adenoid Cystic Carcinoma of the Head and Neck.

BackgroundDespite Adenoid cystic carcinoma (ACC) with cribriform or tubular components being recognized as a potentially indolent malignancy, ACC displaying solid or, more rarely, high-grade transformation (HGT) components is considered a more aggressive variant of the disease. As it is difficult to measure the proportion of the solid component objectively, and the role of HGT in the current grading system remains unclear, the prognostic influence of tumor grading remains controversial. In addition, postoperative radiotherapy (PORT) has been proven to be effective in local control of ACC of the head and neck (ACCHN) with a high rate of nerve invasion and close surgical margin. However it remains to be explored that whether PORT could improve the survival of patients with ACC, particularly those with HGT.MethodsA series of 73 surgically treated primary ACCHN cases were retrospectively accessed. Immunohistochemical staining was performed to observe the biphasic ductal-myoepithelial differentiation and to identify the HGT components of ACC for tumor grading. The correlation between tumor grading and clinicopathological characteristics was analyzed. Univariate and multivariate prognostic analysis were performed for progression-free survival (PFS) and overall survival (OS).ResultsOf the 73 included cases, 47 were grade I-II ACC and 26 were grade III ACC. Among the grade III cases, 14 with loss of biphasic ductal-myoepithelial differentiation identified by immunostaining were classified as HGT, and could be distinguished from conventional grade III cases. These HGT cases were correlated with a high propensity of lymph node metastases and more advanced stage. Univariate analysis demonstrated that tumor grading, perineural invasion, T stage, stage groups, and PORT were predictors for PFS, whereas tumor grading, margin status, and PORT were predictors for OS. However, only tumor grading and PORT were independent predictors for PFS and OS. The patients with HGT had significantly worse prognosis than those with conventional ACC. Moreover, disease progression tended to occur more frequently in younger patients. Among the patients with HGT, those who received PORT had a longer median survival time than those who did not.ConclusionHGT ACC identified by loss of biphasic differentiation should be considered in tumor grading. Tumor grading and PORT were independent predictors for disease progression and OS in surgically treated ACCHN patients.

The clinical characteristic treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck

Objective: To explore the clinical characteristics, treatment strategy and prognosis of adenoid cystic carcinoma of the head and neck (ACCHN). Methods: A retrospective analysis of the clinical and follow-up treatment of 79 patients with ACCHN from June 2008 to July 2017 was conducted in the Cancer Hospital of Zhengzhou University. Results: A total of 79 ACCHN cases, including 31 males and 48 females. The age ranged from 19 to 77 (median, 52). The clinical manifestations of ACC were related to the locations of primary tumor.The mean size of the tumor was 2.6 cm (range from 1.5 to 7.7 cm). 50 of 79 patients with a definitive pathological diagnosis received surgical resection. 59 cases received chemotherapy and 62 cases received radiotherapy. With a median follow-up of 55 months, the 5-year, 10-year survival rate of these patients were 69.6% and 54.4%, respectively. Conclusions: ACCHN is an uncommon neoplasm with the characteristics of epithelial nerve growth, being inclined to distant metastasis, and high early misdiagnosis rate. The clinical manifestation, imaging and pathological result are need to be combined together to diagnose ACCHN.

Adenoid cystic carcinoma of the head and neck: a retrospective multicenter study

Background: Adenoid cystic carcinoma of the head and neck (ACCHN) is rare and difficult to study effective treatment at one institute. Our aim is to identify prognostic factors for this disease by conducting a multicenter study at 11 institutions in Japan.Methods: A retrospective multicenter study of ACCHN was performed. One hundred and three patients were identified between 2006 and 2015. The overall survival (OS) rate for all patients was calculated, and OS, locoregional control (LRC) rate, or no distant metastasis (NDM) rate was calculated for patients in that the surgery was performed without distant metastasis (DM). Statistical analyses were performed.Results: A significant difference with multivariate analysis was observed in patients in sublingual glands, stage IV and the use of radiation therapy ≥60Gy (sufficient RT) in OS for all patients. A significant difference was observed in the use of sufficient postoperative RT in the OS and the LRC rate, and in pathological surgical margins in the NDM rate.Conclusion: Sublingual glands or stage IV was a poorer, and sufficient RT was a better prognostic factor for ACCHN. Sufficient RT was effective to prevent local recurrence after surgical resection. Positive surgical margins caused an increase in DM.

Clinical outcome and clinicopathological prognostic factors in adenoid cystic carcinoma of the head and neck

We retrospectively reviewed the records of the 30 patients with adenoid cystic carcinoma of the head and neck (ACCHN) who had undergone initial treatment in the Department of Otorhinolaryngology, Head and Neck Surgery, Keio University School of Medicine between 1988 and 2007. The primary tumor site was the parotid gland in 10 patients and the submandibular gland in 4 patients, which account for about a half of the subjects. Thirty patients underwent surgical resection with curative intent as the primary treatment, of which 10 patients had post-operative radiotherapy. The 5-and 10-year disease-specific survival (DSS) was 73.9% and 62.4%, respectively, whereas the 5-and 10-year disease-free survival (DFS) was 64.3% and 59.7%, respectively. A univariate analysis revealed that DSS was significantly correlated with perineural invasion (p = 0.010) and lymphatic invasion (p = 0.036), while DFS was significantly correlated with higher T-stage (p = 0.044), a positive surgical margin (p = 0.012) and perineural invasion (p = 0.019). A multivariate analysis demonstrated that perineural invasion (p = 0.034, risk ratio = 9.530) was the independent prognostic factor for DSS, whereas for DFS it was a positive surgical margin (p = 0.038, risk ratio = 8.897). The histological grade classification, defined specifically for ACC, showed no correlation with the survival. Extended resection with wider margin and additional resection in cases with positive margin may improve treatment results, however, surgical resection alone can prevent neither the development of local recurrence mainly attributed to undetectable perineural invasion, nor that of delayed distant metastasis. Therefore, the roles of adjuvant radiotherapy and effective systemic therapies are also significant in ACCHN, although a reliable regimen for the latter has not yet been established. Development of a personalized strategy for the adjuvant therapy, which should be based on the accurate prediction of the long-term prognosis in combination with dependable molecular biomarkers, would be indispensable in the future to improve the clinical outcome of the patients with ACCHN.

Adenoid cystic carcinoma of the head and neck: Clinicopathologic analysis of 218 cases in a Chinese population

The aim of this study was to analyze the clinicopathologic characteristics and prognostic factors of adenoid cystic carcinoma of the head and neck (ACCHN). This was a retrospective study of 218 patients with ACCHN. The cohort included 110 men and 108 women; the parotid and the palate were the most common site of involvement. Of 203 patients with follow-up information (range 2-132 months), 57 had died of the tumor. Distant metastasis (DM) and local recurrence (LR) were documented in 83 (40.9%) and 34 (16.7%) patients, respectively. Cox regression analysis indicated that a solid pattern was a marker for LR and that positive margins and older age were risk factors for DM. Histologic pattern, T stage, N stage, LR, DM, and patient age contributed to the prediction of disease-specific survival. A solid pattern, metastasis, LR, and older age are the most important factors for predicting poor prognosis in Chinese patients with ACCHN.

Clinical Characteristics and Prognostic Factors of Adenoid Cystic Carcinoma of the Head and Neck

This study was intended to evaluate prognostic factors and the role of postoperative radiotherapy (RT) in patients with adenoid cystic carcinoma (ACC) of the head and neck (ACCHN). Retrospective study. Eighty-eight patients with ACCHN who underwent curative intent surgery with or without RT between 1991 and 2009 at a single institute were retrospectively analyzed. Patients with ACC of the sinonasal area (P=.005) and those with diabetes mellitus (DM; P=.027) showed a significantly higher risk of local recurrence. Age (<40 or >60 years, P=.028) and tumor stage III or IV (P=.022) were significant adverse factors predicting distant metastasis. High-grade histology (P=.014) and DM (P=.027) were independently associated with shorter disease-free survival (DFS). In addition, postoperative RT (≥59 Gy) significantly enhanced local control (P=.025) and DFS (P=.001) in both univariate and multivariate analyses. Age, DM, tumor site, histologic grade, and stage were independently significant prognostic factors for ACCHN. In addition, an adequate dose of postoperative radiotherapy can improve local control and DFS of patients with ACCHN.

Adenoid cystic carcinoma of the head and neck

Adenoid cystic carcinoma (ACC) of the head and neck (ACCHN) is a rare tumor of minor salivary, parotid, and submandibular glands. The biologic behavior of the disease is poorly understood, and nonsurgical treatment strategies have yet to be standardized. The long-term prognosis continues to be guarded, with an estimated 10-year survival of <60%. Population-based studies examining ACC are scarce. The authors aimed to analyze incidence rates and survival outcomes for patients diagnosed with ACCHN using national population-based data. Data were obtained from the US National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. Newly diagnosed ACCHN cases reported to SEER from 1973 through 2007 were categorized according to their sex, race, age, year of diagnosis, marital status, treatment interventions, primary tumor site, and disease stage. Incidence of ACCHN and postdiagnosis survival were examined over time and compared across different demographic and disease-related categories. The authors identified 3026 patients with ACCHN. The mean age at diagnosis among those cases was 57.4 years (range, 11-99 years). Analyses of incidence data demonstrated a decline in ACCHN rates between 1973 and 2007, noted across all sexes and races with no detectable inflexion points. The overall 5-year, 10-year, and 15-year survival outcomes for ACCHN patients were 90.3%, 79.9%, and 69.2%, respectively. Females, patients with localized disease, and younger patients were found to have significantly better survival across all time periods (all comparison-specific log-rank P values <0.001). Multivariate analyses revealed better prognosis among women compared with men (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.65-0.82), among married compared with unmarried individuals (HR, 0.81; 95% CI, 0.71-0.91), with certain sites of origin and stage of disease (HR, 2.788; 95% CI, 2.36-3.29), and in those who had surgery of the primary tumor site (HR, 0.45; 95% CI, 0.37-0.54). The overall incidence of ACC is declining. The noted differences in survival based on sex, marital status, site of origin, and treatment intervention require further investigation.

Expression of intercellular adhesion molecule (ICAM)-1 in adenoid cystic carcinoma of the head and neck.

Adenoid cystic carcinoma of the head and neck (ACCHN) is characterized by late recurrence and frequent distant metastasis. Tumor attack by cytotoxic T lymphocytes and macrophages is mediated by the interaction of leukocyte function-associated antigen (LFA)-1 on lymphocytes with intercellular adhesion molecule (ICAM)-1 on the tumor surface. Thus, the reduced expression of ICAM-1 on tumor cells could contribute to their escape from host immune surveillance. To investigate the relationship between the clinical features of ACCHN and host immune surveillance, the expression of ICAM-1 and infiltration of T/natural killer (NK) cells and macrophages were immunohistochemically examined. Retrospective analysis of immunohistochemical tumor characteristics and clinical outcome. Immunohistochemical study of ICAM-1, T/NK cells, and macrophages was performed on paraffin sections of 42 patients with ACCHN. The expression of T/NK cells and macrophages was represented by T-cell-restricted antigen (TIA)-1 and CD68 expression, respectively. The expression of these molecules and clinical features were analyzed. Of 42 ACCHN cases, 15, 9, and 15 patients were classified as ICAM-1 high, TIA-1 high, and CD68 high, respectively. The TIA-1 expression scores in ICAM-1-low patients were significantly lower than those in ICAM-1-high patients (1.3 +/- 3.7 vs. 8.3 +/- 12.7, P =.0031). The CD68 expression scores in ICAM-1-low patients were also significantly lower than those in ICAM-1-high patients (9.6 +/- 9.6 vs. 21.1 +/- 17.6, P =.0047). Moreover, ICAM-1-high patients had a significantly better disease-free survival rate (P =.043). Reduced expression of ICAM-1 may promote immune evasion and metastasis, resulting in poor prognosis in ACCHN.

Neural cell adhesion molecule expression in adenoid cystic carcinoma of the head and neck.

To investigate whether there is a correlation between neural cell adhesion molecule (NCAM) expression and perineural spread in patients with adenoid cystic carcinoma of the head and neck (ACCHN). Retrospective review of medical records and immunohistochemical staining of specimens from 37 patients treated at the University of Arkansas in Little Rock from 1987 to 1997. Sections from paraffin-embedded specimens were examined for the presence of NCAM using monoclonal anti-NCAM antibody by avidin-biotin-peroxidase immunohistochemical staining. NCAM staining was scored in each specimen and correlated with the data obtained from patient charts. Twenty-five of 37 specimens (68%) showed histopathological evidence of perineural spread. All 37 specimens (100%) stained positive for NCAM, regardless of perineural spread status. Our results suggested that the use of NCAM expression as a predictor of perineural spread is highly unlikely.
