Our results for 5-year survival are comparable to those in the literature with a treatment based on complete surgical resection. The only significant prognostic factor was tumor histological grade.
OBJECTIVE:We aimed to estimate the overall survival (OS) and conditional survival (CS) in patients diagnosed with oral and oropharyngeal squamous cell carcinoma (SCC) and to determine their survival trends.
METHODS:The study included all consecutive patients treated at the A.C. Camargo Cancer Center for oral or oropharyngeal SCC between 2001 and 2012. Data were obtained from the Hospital Cancer Registry. OS and CS were analyzed using the Kaplan-Meier method to evaluate the probability of survival with Cox predictor models. RESULTS: Data of 505 oral and 380 oropharyngeal SCC patients obtained in 2001-2006 and 2007-2012 were analyzed. Most of the oral SCC (59%) and oropharyngeal SCC (90%) patients had stages III-IV SCC. The 5-year OS for patients with oral SCC was 51.7%, with no significant difference between the first and second periods. The CS rates in 2007-2012 were 65% after the first year and 86% up to the fifth year. For oropharyngeal SCC, the 5-year OS rate was 45.0% in the first period. The survival rate increased to 49.1% from 2007 to 2012, with a reduction in the risk of death (HR=0.69;0.52-09.2). The CS estimates from 2007 to 2012 were 59% after the first year and 75% up to the fifth year. CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients' response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.
Galectin-3 could be a good tool to guide therapeutic decision in patients with thyroid nodules and FNAB results of follicular neoplasm, but available information has methodological flaws that precludes a definitive answer about galectin-3 utility in the clinical setting.
Outcomes with a significant relationship to not obtain complete functional and aesthetic restoration included involvement of both eyelids, upper-eyelid involvement, older age, bilateral involvement, diffuse facial pattern OVAs, and OVAs with dimensions greater than one third of the orbit dimension.
e23550 Background: Head and neck soft-tissue sarcoma (HN-STS) is a rare entity for which a new prognostic risk stratification has been proposed in the 8th AJCC. The tumor size 2cm and 4cm have been adopted as cutoffs for T1 to T3 classification and the invasion of surrounding structures denotes T4. In opposite, in the 7th edition the primary tumor size of 5 cm determines T1 and T2 classification. This study aimed to compare the 8th and 7th AJCC as a prognostic tool for HN-STS. Additionally, we sought to investigate prognostic factors in this group of patients. Methods: This is a single Tertiary Hospital study approved by the institutional ethical review committee from the AC Camargo Cancer Center. We retrospectively evaluated patients with non-metastatic HN-STS whose histology subtypes are included in the 40th chapter of the 8th AJCC version. We compared the AJCC 7th and 8th T staging with Cohen’s kappa coefficient using inter-rater agreement analysis. The Kaplan-Meier (KM) estimator was used to calculate median survival times; differences in time-to-event outcomes were assessed using the log-rank test. Cox proportional hazard model was used to assess the effect of features in overall survival (OS). Results: Ninety-five HN-STS treated with curative intent from 2005 from 2021 patients diagnosed were evaluated. Surgical resection (94.7%), radiotherapy (48.4%) and chemotherapy (23.1%) were the employed therapeutic approaches. Leiomyosarcoma and liposarcoma (10 of each subtype) were the most common histology subtypes; High grade disease was present in 66.3%. Kappa coefficient of inter-rater agreement was 0.46 with statistical significance (p = 0.03), which indicates poor agreement between AJCC 7th and 8th T staging system. Regarding OS stratified by T size in the AJCC 7th (T1 and T2) and 8th (T1, T2, T3 and T4) was not statistically different between groups (P = 0.83 and P = 0.21, respectively). Patients with T4 (47.6% vs 78.7%, P = 0.04) and high grade (64.0% vs 96.2%, P = 0.003) had worst 5-years OS. In Cox multivariate analysis, patients with 8th edition T4 and high grade had 3.15- and 4.16-fold increased risk of death, respectively. Conclusions: In our series of patients with HN-STS, neither 7th nor 8th AJCC T size category groups discriminated prognosis. Tumor with local invasion (8th AJCC T4) and high grade were all associated with increased risk of mortality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
