Purpose: For cervical carcinoma, postoperative radiation therapy (PORT) following radical hysterectomy (RH) is indicated for certain adverse pathological factors. Simple hysterectomy (SH) is considered inadequate treatment for invasive cervical carcinoma and PORT is required for all such cases. Clinical outcome of patients receiving PORT following SH and RH may be different. The aim of our retrospective study is to compare the results of PORT following inadvertent SH or RH in cervical carcinoma.
Materials And Methods: During years 2003-2005, we treated 83 patients with cervical carcinoma with PORT following either SH (Group SH, 33 patients) or RH (Group RH, 50 patients). All patients were treated with pelvic external beam radiation therapy (EBRT) followed by intravaginal brachytherapy (IVBT). The endpoints of the study were local control, recurrence free survival (RFS) and delayed complications.
Results: Median follow period up was 34 months (range 2-75 months). Local control rate observed in Gp SH and RH was 70% and 88% respectively with a p value of <0.05. Cumulative 5-year overall survival (OS) for combined group was 62%. Group RH patients had significantly better 5-year RFS than Group SH patients (72% and 49% respectively; p value 0.04). The frequency of Grade III-IV toxicity (bladder, rectum, and bowel) in Group SH versus Group RH was 6% vs 8% respectively (p value 0.1). The pedal lymph edema was higher in Group RH patients (10% vs 3%, p value<0.05).
Conclusion: PORT provides greater clinical benefit in patients who had undergone RH than SH for early stage invasive cervical carcinoma.

Background: BERIL-1 was a randomized phase 2 study that studied paclitaxel with either buparlisib, a pan-class I PIK3 inhibitor, or placebo in patients with recurrent or metastatic (R/M) head and neck squamous cell cancer (HNSCC). Considering the therapeutic paradigm shift with immune checkpoint inhibitors (ICIs) now approved in the first-line setting, we present an updated immunogenomic analysis of patients enrolled in BERIL-1, including patients with immune-infiltrated tumors.
Objective: The objective of this study was to identify biomarkers predictive of treatment efficacy in the context of the post-ICI therapeutic landscape.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.

Although sialoblastoma (SBL) is defined as a low-grade malignant salivary gland anlage neoplasm in the 2022 World Health Organization (WHO) Classification of Head and Neck Tumors, its histology, genetics, and behavior remain controversial due to the rarity of the tumor. Here, we performed the first comprehensive clinical, histologic, and molecular analyses of 8 SBLs to better understand their pathogenesis and prognosis. This cohort consisted of 5 boys and 3 girls, with ages ranging from birth to 9 years at diagnosis.
