Objectives: Whether to perform elective neck dissection (END) or apply the observation (OBS) policy in patients with early-stage oral squamous cell carcinoma (OSCC) without clinical evidence of cervical lymph node metastasis (cT1/T2N0) remains uncertain. The two most recent meta-analyses include many studies published before the widespread availability of CT scanning in the 1990s. With the rapid advancement in imaging studies since 1990, the early clinical detection of cervical node metastasis has become more reliable without the need for END or pathological staging. Thus, we conducted a systematic review and meta-analysis of studies comparing survival outcomes between END and OBS in patients with cT1/T2N0 OSCC.

Methods: We performed a systematic search of MEDLINE, PubMed, and Scopus for retrospective and prospective studies published between January 1, 1990, and January 1, 2018, comparing clinical outcomes between END and OBS in patients with cT1/T2N0 OSCC. Information on population characteristics, study design, overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS) was extracted and estimated. Effect measures for outcomes were hazard ratios (HRs) and 95% confidence intervals (CIs).

Results: Thirteen retrospective and two prospective randomized studies (3,158 patients) met the inclusion criteria. Compared to OBS, END failed to significantly improve OS (HR, 1.02; 95% CI, 0.95-1.09; = .77; fixed-effects model), DSS (HR, 1.07; CI, 1.02-1.13; = .31; fixed-effects model), and DFS (HR, 0.86; CI, 0.72-1.01; = .12; random-effects model).

Conclusions: Our findings indicate that in patients with cT1T2N0 OSCC, the OBS policy can yield markedly similar OS, DSS, and DFS to those resulting from END.

Level Of Evidence: 2.

Objectives: To address controversies regarding target volume delineation for adjuvant intensity-modulated radiation therapy for oral cavity squamous cell carcinoma with pedicled flap reconstruction and elective nodal irradiation (ENI).

Materials And Methods: During target volume delineation, the primary tumor bed was the pre-surgical gross tumor volume with an additional isotropic margin of 5-10 mm. Additionally, the flap and body tissue junction were given a margin of 5-10 mm (if not already given).

An obturator hernia (OH) is a rare type of hernia that accounts for a very small proportion of all hernias and cases of small bowel obstruction. This condition predominantly affects older, underweight individuals, with the vast majority of patients being women. Laparotomy with simple suture closure of the defect is commonly used as surgical treatment for OH.

Article Synopsis
  • The study examined the risk factors for developing type I endoleak in patients undergoing elective endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA).
  • A total of 105 patients were analyzed, dividing them into those who experienced endoleak (23) and those who did not (82), comparing demographic and clinical characteristics between the two groups.
  • High hostile neck index (HNI) was identified as a significant independent predictor of type I endoleak, with a specific cut-off value determined for predicting endoleak risk.

Purpose: To evaluate treatment outcomes and toxicity in patients with stage T1-3N0M0 oral cancer treated with surgery followed by high-dose-rate brachytherapy (HDR-BT).

Methods And Materials: Retrospective study of 50 patients with stage T1-T3N0 tongue and floor-of-mouth cancer who underwent tumour excision (+ elective neck dissection) followed by postoperative HDR-BT due to the presence of negative prognostic factors (close or positive resection margins, lymphovascular and/or perineural invasion, deep invasion). The plastic tube technique (dose: 18 x 3 Gy b.
