Aim: This study aimed to identify the most effective treatment mode for locally advanced cervical cancer (LACC) by adopting a network meta-analysis (NMA).
Methods: Randomized controlled trials about treatments were retrieved from PubMed, Medline and Embase. Odds ratios (OR) of overall survival (OS) and progression-free survival (PFS) were calculated by synthesizing direct and indirect evidence to rank the efficacy of nine treatments. Consistency was assessed by node-splitting method. Begg's test was performed to evaluate publication bias. The surface under cumulative ranking curve (SUCRA) was also used in this NMA.
Results: A total of 24 eligible randomized controlled trials with 6,636 patients were included in our NMA. These trials compared a total of nine different regimens: radiotherapy (RT) alone, surgery, RT plus adjuvant chemotherapy (CT), concurrent chemoradiotherapy (CCRT), neoadjuvant CT plus CCRT, CCRT plus adjuvant CT, neoadjuvant CT, RT, CCRT plus surgery. Among those therapeutic modalities, we found that the two interventions with the highest SUCRA for OS and PFS were CCRT and CCRT plus adjuvant CT, respectively. ORs and 95% confidence interval (CI) for the two best strategies were CCRT versus CCRT plus adjuvant CT (OR, 0.84; 95% CI, 0.53-1.31) for OS, CCRT plus adjuvant CT versus CCRT (OR, 0.60; 95% CI, 0.38-0.96) for PFS.
Conclusions: This NMA supported that CCRT and CCRT plus adjuvant CT are likely to be the most optimal treatments in terms of both OS and PFS for LACC. Future studies should focus on comparing CCRT and CCRT plus adjuvant CT in the treatment of LACC.

Background: Nasopharyngeal carcinoma (NPC) is a prevalent form of head and neck cancer, particularly in specific regions with a higher incidence. The optimal treatment strategy for locally advanced NPC (stage III and IVA, LA-NPC) involves various combinations of induction chemotherapy (IC), concurrent chemoradiotherapy (CCRT), and adjuvant chemotherapy (AC), each with distinct advantages. This one institutional study aims to retrospectively analysis the efficacy and clinical outcomes of IC with CCRT (IC+CCRT), CCRT with AC (CCRT+AC), and the comprehensive approach of IC followed by CCRT and subsequently AC (IC+CCRT+AC) in the management of LA-NPC.

Objective: The aim of this study was to assess the effect of postoperative chemotherapy on the survival of surgically treated patients with T1b uterine cervical cancer.
Methods: Overall, 1687 patients with T1b cervical cancer who received concurrent chemoradiotherapy (CCRT) or chemotherapy as postoperative adjuvant therapy were retrospectively analyzed using the Japan Society of Obstetrics and Gynecology cancer registry program data from 2015 to 2016. After propensity score matching, overall survival (OS) was compared between 643 patients treated with CCRT and 643 patients treated with chemotherapy.

Background: Sinonasal squamous cell carcinoma (SCC) is a rare disease entity, comprising less than 5% of malignancies of the head and neck. While surgery is the primary treatment approach, neoadjuvant and adjuvant therapies play crucial roles in enhancing the prognosis of patients undergoing treatment with the goal of cure. In this study, we aimed to explore the treatment outcomes of neoadjuvant chemotherapy (NAC) in patients with locally advanced sinonasal SCC.

Article Synopsis
- * A specific case is discussed where a patient with intrahepatic cholangiocarcinoma experienced lymphatic recurrence post-surgery and adjuvant therapy but responded exceptionally well to a combination of Opdivo (nivolumab), chemotherapy, and hyperthermia.
- * The patient achieved a complete response with no further lymph node metastasis and a significant drop in tumor marker CA 19-9, indicating the potential effectiveness of combining different therapies in treating this challenging cancer type.
