Perioperative interstitial high-dose-rate brachytherapy for keloids scar.

Purpose: To evaluate the results of keloids treated with perioperative interstitial high-dose-rate brachytherapy (HDR-BT).

Material And Methods: A retrospective review of 61 keloids in 51 patients treated with perioperative interstitial HDR-BT was performed. Keloid lesions were treated with 12 Gy in 4 fractions within 48 hours.

Expanding an expanded genome: long-read sequencing of Trypanosoma cruzi.

Although the genome of Trypanosoma cruzi, the causative agent of Chagas disease, was first made available in 2005, with additional strains reported later, the intrinsic genome complexity of this parasite (the abundance of repetitive sequences and genes organized in tandem) has traditionally hindered high-quality genome assembly and annotation. This also limits diverse types of analyses that require high degrees of precision. Long reads generated by third-generation sequencing technologies are particularly suitable to address the challenges associated with T.

[Treatment results with external radiotherapy in prostate cancer].

Objective: External irradiation is an accepted curative treatment modality for patients with localized prostatic tumor. The 15-year results in patients treated by radical irradiation alone are presented. The determinant prognostic factors for local tumor control and disease free survival are analyzed.

Control of neck nodes in squamous cell carcinoma of the head and neck by radiotherapy: prognostic factors.

313 patients with cervical metastases from a squamous carcinoma of the head and neck treated with radiotherapy, were studied by means of a multivariant analysis in order to determine the prognostic factors for cure. These were: lymph node response to irradiation (P = 0.0000), size of node (P = 0.
