Background and Objectives: We analyzed the data of oropharyngeal squamous cell carcinoma (OPSCC) patients who had transoral surgery with/without adjuvant therapy and experienced recurrence. From the data, the treatment outcomes and prognostic factors of recurrent OPSCC were evaluated, and the predictive factors related to successful salvage treatment were identified.Subjects and Method We used data from patients who were diagnosed with OPSCC and received transoral surgery at the hospital from January 2005 to December 2019. Results: The 5-year survival rate of patients with recurrent OPSCC was 43.9%. The predictors of successful salvage treatment were adjuvant therapy and the p16 status. The 5-year survival rate following salvage treatment for patients who had recurrent OPSCC and also tested p16-positive was 64%; however, it was only 30% for patients who had recurrent OPSCC and tested p16-negative. The 5-year survival rate was 22% for patients who received adjuvant therapy and 64% for those who did not receive it. Conclusion In OPSCC patients who recurred after transoral surgery with/without adjuvant therapy, the salvage treatment success rate was 45%. In recurrent cancer, the HPV status was an important factor associated with successful salvage treatment, as the success rate of salvage treatment was remarkably high in patients who did not receive adjuvant therapy. Thus, we verified that it is crucial to conduct an initial surgery with clear margins and determine the optimal criteria for adjuvant therapy.

Background and Objectives: We analyzed the treatment results and prognostic factors of stage IV oral tongue squamous cell carcinoma (OTSCC) patients and explored the existence of subgroups with distinctive prognoses. In addition, the outcome of salvage therapy was analyzed in recurrent cases, and the survival rates and prognostic factors were investigated.Subjects and Method This study was conducted on patients who were diagnosed with OTSCC and underwent surgery at our hospital between June 2005 and January 2020. A total of 144 patients with stage IV OTSCC was enrolled. Results: A total of 64 recurrences, local (6), regional (21), distant metastasis (33), and locoregional (4), occurred. Seventy-five patients died because of disease progression during the course of study. The 5-year recurrence-free survival rate was 54.5%, and the 5-year disease-specific survival rate was 49.2%. Surgical margins, lymphovascular invasion (LVI), T classification, and lymph nodes (LNs) metastasis exhibited significant correlation with mortality. LVI and advanced T were statistically important factors for predicting distant metastasis. The treatment outcome of the T4N0 patient group without LN metastasis fared the best, while the treatment outcome of the T4N1-3 patient group with advanced T and N findings was the worst. Conclusion The major type of treatment failure in stage IV OTSCC patients was distant metastasis, and the related predictors of distant metastasis were LVI and advanced T. In the stage IV OTSCC patient group, there were subgroups with distinct prognosis according to the combination of T and N classification. The T4N0 group had the best survival rate, and the T4N1-3 group had the worst prognosis.

With advancements in both pharmacologic and non-pharmacologic treatments, significant changes have occurred in heart failure (HF) management. The previous Korean HF registries, namely the Korea Heart Failure Registry (KorHF-registry) and Korean Acute Heart Failure Registry (KorAHF-registry), no longer accurately reflect contemporary acute heart failure (AHF) patients. Our objective is to assess contemporary AHF patients through a nationwide registry encompassing various aspects, such as clinical characteristics, management approaches, hospital course, and long-term outcomes of individuals hospitalized for AHF in Korea. This prospective observational multicenter cohort study (KorHF III) is organized by the Korean Society of Heart Failure. We aim to prospectively enroll 7,000 or more patients hospitalized for AHF at 47 tertiary hospitals in Korea starting from March 2018. Eligible patients exhibit signs and symptoms of HF and demonstrate either lung congestion or objective evidence of structural or functional cardiac abnormalities in echocardiography, or isolated right-sided HF. Patients will be followed up for up to 5 years after enrollment in the registry to evaluate long-term clinical outcomes. KorHF III represents the nationwide AHF registry that will elucidate the clinical characteristics, management strategies, and outcomes of contemporary AHF patients in Korea.
