The Italian Association of Radiotherapy and Oncology Recommendation for Breast Tumor Recurrence: Grades of Recommendation, Assessment, Development and Evaluation Criteria.

J Breast Cancer 2021 May 13. Epub 2021 May 13.

Radioterapia, Dipartimento di Biomedicina e prevenzione, Università degli Studi di Roma Tor Vergata, Roma, Italy.

Salvage mastectomy is currently considered the standard of care for ipsilateral breast tumor recurrence (IBTR) after breast-conserving surgery (BCS) and postoperative radiotherapy (RT). Alternative treatment options for these patients, such as a second BCS followed by repeated RT, have been suggested. The panel of the Italian Association of Radiotherapy and Clinical Oncology developed clinical recommendations for second BCS followed by re-irradiation over mastectomy alone for women with IBTR using the Grades of Recommendation, Assessment, Development, and Evaluation methodology and the evidence to decision framework.

Effectiveness of rectal displacement devices during prostate external-beam radiation therapy: A review.

J Cancer Res Ther 2021 Apr-Jun;17(2):303-310

Department of Medical Physics, School of Medicine, Iran University of Medical Sciences; Department of Medical Physics, Roshana Cancer Institute, Tehran, Iran.

Dose-escalated prostate radiotherapy (RT) can improve treatment outcomes, but rectal toxicity is the main limiting factor for introducing dose-escalated RT. Pushing rectal wall away from the prostate reduces the volume of the rectum in high-dose region, which can decrease both short- and long-term rectal toxicities after RT. This review focuses on the literature using different rectal displacement devices such as endorectal balloons, tissue spacers, rectal retractor, and ProSpare during prostate External beam radiotherapy, with regard to dosimetric effects, clinical benefits, prostate motion, and postoperative RT setting.

Updated Treatment for Acne: Targeted Therapy Based on Pathogenesis.

Dermatol Ther (Heidelb) 2021 Jun 11. Epub 2021 Jun 11.

Department of Plastic, Reconstructive and Aesthetic Surgery, Nippon Medical School, Tokyo, Japan.

Previous approaches to acne management have focused on the four main factors implicated in acne, namely, androgen-mediated sebogenesis (considered integral to acne), hyperkeratinization, colonization with Cutibacterium acnes, and inflammation related to both innate and adaptive mechanisms. Recent advances have facilitated potential novel approaches to acne management, as the pathophysiology and the immunological aspects related to acne and wound healing have evolved. Particular targets that have been shown to be closely involved in acne pathophysiology and wound healing include interleukin (IL)-1β, IL-17, IL-23, and tumor necrosis factor alpha (TNFα). Read More

Tumor-to-Gland Volume Ratio versus Tumor-to-Breast Ratio as Measured on CBBCT: Possible Predictors of Breast-Conserving Surgery.

Cancer Manag Res 2021 3;13:4463-4471. Epub 2021 Jun 3.

Department of Breast Surgery, Guangxi Medical University Cancer Hospital, Nanning, Guangxi, People's Republic of China.

Background: Breast-conserving surgery plus postoperative radiotherapy is the standard surgical treatment mode for early breast cancer. Currently, there are no clear predictive indicators to determine whether a patient can choose breast-conserving surgery, which mainly depends on the surgeon's clinical experience and subjective judgment. Cone-beam breast computed tomography (CBBCT) reconstructs the breast 3D image from three mutually perpendicular angles, helping surgeons to locate and accurately measure the volume of the tumor, mammary gland, and breast.

Salvage surgery after definitive chemoradiotherapy through VATS for an initial unresectable locally advanced lung cancer: an alternative consolidative modality to radiotherapy?

Surg Case Rep 2021 Jun 8;7(1):138. Epub 2021 Jun 8.

Division of Thoracic Oncology, Department of Chest Medicine, Taipei Veterans General Hospital, Taipei, Taiwan.

Background: Definitive chemoradiotherapy (dCRT) is the first choice treatment for patients with locally advanced non-small cell lung cancer (NSCLC), but up to 35% of dCRT-treated tumors may have persistent or recurrent disease. Since the last decades, multimodality therapy showing potential for cure has become the mainstream for treatment of locally advanced NSCLCs, even some that were initially inoperable. Although salvage lung resection after dCRT has been reported with acceptable survivals, experiences in this respect are still limited. Read More

No Shinkei Geka 2021 May;49(3):575-587

Department of Radiation Oncology, National Cancer Center Hospital.

Gliomas are infiltrative tumors that are difficult to cure by surgery alone. Postoperative radiotherapy or chemoradiotherapy is the treatment option for patients with high-grade gliomas. However, most pathological types of glioma other than glioblastoma do not have enough evidence, especially concerning the dose-fractionation scheme and clinical target volume definition for radiotherapy.

Preoperative stereotactic ablative body radiotherapy with postoperative conventional irradiation of soft tissue sarcomas: protocol overview with a preliminary safety report.

Radiother Oncol 2021 Jun 2. Epub 2021 Jun 2.

Department of Radiation Oncology & Nuclear Medicine, N.N. Petrov National Medical Research Center of Oncology, St. Petersburg 197758, Russia. Electronic address:

Preoperative radiotherapy in patients with soft tissue sarcomas is characterized by important advantages: high precision of dose delivery, reduction of tumour volume and implantation potential, induction of immunologic response. Postoperative irradiation is associated with a reduced risk of complication, and a comprehensive radiotherapy planning in accordance with the pathologic report. Combination of pre- and postoperative irradiation gives the opportunity to use the best of both methods. Read More

Authors:

BJS Open 2021 May;5(3)

Background: A resection with clear margins (R0 resection) is the most important prognostic factor in patients with locally recurrent rectal cancer (LRRC).

Mucosa plication reinforced colorectal anastomosis and trans-anal vacuum drainage: a pilot study with preliminary results.

Updates Surg 2021 Jun 5. Epub 2021 Jun 5.

Laboratory of Bioinformatics and Biostatistics, Jessenius Medical Faculty in Martin, Biomedical Center Martin, Comenius University in Bratislava, Martin, Slovak Republic.

Dehiscence of colorectal anastomosis is a serious complication that is associated with increased mortality, impaired functional and oncological outcomes. The hypothesis was that anastomosis reinforcement and vacuum trans-anal drainage could eliminate some risk factors, such as mechanically stapled anastomosis instability and local infection. Patients with rectal cancer within 10 cm of the anal verge and low anterior resection with double-stapled technique were included consecutively. Read More
