Purpose: To prove the superiority of concurrent radiochemotherapy (RTCT) over radiotherapy (RT) alone in locally advanced cervical carcinoma.
Patients And Methods: In this randomized monocentric phase III study, 566 patients with squamous cell carcinoma of the cervix were included: 284 in arm A (RT) and 282 in arm B (concurrent RTCT with cisplatin 20 mg/m(2) x 5 days). 238 patients (42%) were in stage IIB, 209 (37%) in stage IIIA, and 119 (21%) in stage IIIB. The median follow-up was 62.8 months. RT to the pelvis was delivered to a dose of 46 Gy/23 fractions. A cervical boost was given using the X-ray arch technique or high-dose-rate intracavitary brachytherapy at a dose of 10 Gy. Thereafter, patients were evaluated: those with good response optionally underwent surgery and the others continued RT until 64 Gy/pelvis (with or without CT according to randomization) and 14 Gy/central tumor volume.
Results: The 5-year survival rate was statistically significantly superior in the concurrent RTCT group (74%) versus the RT group (64%; p < 0.05). In patients undergoing surgery after RT or RTCT, superior results were obtained, compared to the nonoperated patients: 5-year survival rate 86% versus 53% (p < 0.01). 192 failures were recorded: 109 (38%) after RT alone versus 83 (29%) after concurrent RTCT (p < 0.01).
Conclusion: The results of this study prove the obvious superiority of concurrent RTCT with 5-day cisplatin compared to RT alone in patients with locally advanced cervical carcinoma, regarding local control (78% vs. 67%) and 5-year survival rates (74% vs. 64%).

Background: Neoadjuvant chemoradiotherapy followed by total mesorectal excision is the standard treatment for patients with nonmetastatic locally advanced rectal cancer (LARC). However, for patients with LARC and synchronous metastasis, the optimal treatment strategy and sequence remain inconclusive. In the present study, we evaluated the efficacy and safety of concurrent radiotherapy in patients with metastatic rectal cancer who received chemotherapy and targeted therapy.

The standard treatment approach in locally advanced cervical cancer (LACC) is exclusive concurrent chemoradiation therapy (RTCT). The risk of local residual disease after six months from RTCT is about 20-30%. It is directly related to relapse risk and poor survival, such as in patients with recurrent cervical cancer.

Cancer growth in host tissues features glutamine (gln) depletion over time, decreasing epithelial cells' optimal functioning. In addition, radiotherapy (RT) and/or chemotherapy (CT) cause damage to normal tissues, probably enhanced by this depletion. The present study prospectively examined the effect of gln supplementation on 72 patients with thoracic and upper aerodigestive malignancies (T&UAM) treated with sequential or concurrent RT-CT or RT alone.

Purpose: Cervical cancer is a global health problem. Despite the growth of prevention programs, there is an important need to improve the effectiveness of treatment for patients with invasive, locally advanced disease. In this study we examined (1) the efficacy of radiation therapy (RT) with cisplatin (RTCT) and an orally administered CXCR4 inhibitor suitable for clinical use, X4-136; (2) biomarkers of response to RTCT and X4-136; and (3) intestinal toxicity from RTCT and X4-136.

Objective: To compare the efficacy and tolerance of 7-days-a-week accelerated postoperative radiotherapy (p-CAIR) postoperative radio-chemotherapy (p-RTCT).
Methods: Between September 2007 and October 2013, 111 patients were enrolled and randomly assigned to receive 63 Gy in 1.8 Gy fractions 7-days-a-week ( = 57, p-CAIR) or 63 Gy in 1.
