Treatment of rectal cancer has markedly improved since the introduction of neoadjuvant strategies and better surgical techniques. However, treatment remains troublesome for patients with locally advanced rectal cancer (LARC) or with peritoneal carcinomatosis (PC). Patients presenting with LARC may now benefit from the integration of intra-operative radiotherapy (IORT) into multimodality treatment. Selected patients with PC now undergo cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC) resulting in improved survival. Some patients present with locally advanced disease and synchronous peritoneal carcinomatosis and fulfill the eligibility criteria for both HIPEC and IORT, raising the question whether the combined application of both modalities within one operative procedure is feasible. ⋯ The current case series shows that a multimodality treatment containing IORT and HIPEC is feasible and safe with promising survival rates. This strategy may, therefore, be considered in selected rectal cancer patients presenting with both LARC and synchronous PC.

Comparative Study
Intensity-modulated radiotherapy vs. parotid-sparing 3D conformal radiotherapy. Effect on outcome and toxicity in locally advanced head and neck cancer.
Intensity-modulated radiotherapy (IMRT) has rapidly become standard of care in the management of locally advanced head and neck squamous cell carcinoma (HNSCC). In this study, our aim was to retrospectively investigate the effect of the introducing IMRT on outcome and treatment-related toxicity compared to parotid-sparing 3D conformal radiotherapy (3DCRT). ⋯ The introduction of IMRT in the radiotherapeutic management of locally advanced head and neck cancer significantly improved late toxicity without compromising tumor control compared to a parotid-sparing 3D conformal radiotherapy technique.

Controlled Clinical Trial
Diffusion-weighted MRI in locally advanced rectal cancer : pathological response prediction after neo-adjuvant radiochemotherapy.
The aim of this study was to assess the predictive potential of diffusion-weighted magnetic resonance imaging (MRI) for the selection of favorable pathological responders after radiochemotherapy for locally advanced rectal cancer. ⋯ Low preradiochemotherapy ADC values and high ΔADC correspond to pathological good response. Diffusion-weighted MRI may be used as an additional tool for selecting good treatment responders after radiochemotherapy.

To create a validated scoring system predicting survival of breast cancer patients with metastatic spinal cord compression (MSCC). ⋯ The survival rates of the validation group were similar to the test group. Therefore, this score was reproducible and can help when selecting the appropriate radiotherapy regimen for each patient taking into account her survival prognosis.

This study aimed to identify independent prognostic factors and to create a survival score for patients with metastatic spinal cord compression (MSCC) from colorectal cancer (CRC). ⋯ This study identified several independent prognostic factors for treatment outcomes in patients irradiated for MSCC from CRC. The survival prognosis of these patients can be estimated with a new score.
