Purpose: Variations in the levels of systemic inflammatory biomarker levels have been linked with outcomes in various malignancies including cervical cancer. In this study, we investigated prognostic implications of pretreatment hematological factors/indices in locally advanced cervical cancers treated with radical radio(chemo)therapy.

Methods And Materials: Electronic medical records of 1051 patients with cervical cancer of FIGO (International Federation of Gynecology and Obstetrics) stage IB2-IVA treated in various prospective trials at our institute between 2003 and 2017 were reviewed.

Purpose: Recent evidence from EMBRACE shows that around 16% patients with locally advanced cervical cancer (LACC) have residual tumor in distal parametrium (DP) and pelvic wall disease (LPW) after concurrent radio-chemotherapy (CCRT). Adequate target coverage with standard brachytherapy approaches represents a challenge. Therefore, we modified the Vienna I applicator with an add-on cap allowing for additional oblique needles into the DP/LPW (Vienna II).

Purpose: Although magnetic resonance imaging (MRI) represents the gold standard for image guided adaptive brachytherapy (IGABT) for cervical cancer, the majority of brachytherapy (BT) continues to be guided by computed tomography (CT). However, CT seems to overestimate the target-volume definition, and the potential of transrectal ultrasonography (TRUS) needs further evaluation. This prospective, comparative study aimed to evaluate CT-based target contouring with the incorporation of TRUS during BT.

Purpose Of Review: Cervical cancer is still a major cause of morbidity and mortality among women worldwide. Surgery and chemoradiation are widely utilized treatments for cervical cancer. Despite the available standard treatment of choice, outcome is suboptimal among patients with LACC.

Purpose: The purpose of the study was to evaluate the feasibility and efficacy of an accelerated radiotherapy schedule using weekend boost in terms of tumor response, compliance, and acute toxicities for head and neck squamous cell carcinoma, and to report long-term clinical outcomes.

Materials And Methods: Twenty-six patients with stages III-IV head and neck squamous cell carcinoma receiving radical chemoradiotherapy were accrued prospectively into the study. External beam radiation therapy to a total dose of 66-70 Gy in 33-35 fractions, 1.

Purpose: To quantify and compare dose-volume and dose-length parameters of cervical esophagus between three-dimensional conformal radiotherapy (3DCRT) and intensity-modulated radiation therapy (IMRT) and to correlate with incidence of cervical strictures in head and neck cancer irradiation with radical intent.

Materials And Methods: Forty consecutive head and neck cancer patients who received radical radiation therapy, either with 3DCRT (n = 20) or IMRT (n = 20), between December 2011 and August 2012 were retrospectively analyzed and followed up for at least 4 years post-treatment completion.

Results: The volumes of cervical esophagus receiving ≥54 Gy (V54) and ≥60 Gy (V60) and lengths receiving circumferential dose of ≥50 Gy (L50) and ≥54 Gy (L54) were significantly higher in patients treated with IMRT as compared to 3DCRT (P ≤ .
