Post-mastectomy radiation therapy after breast reconstruction: from historic dogmas to practical expert agreements based on a large literature review of surgical and radiation therapy considerations.

Breast reconstruction (BR) after mastectomy is important to consider for a woman's body image enhancement and psychological well-being. Although post-mastectomy radiation (PMRT) significantly improves the outcome of patients with high-risk breast cancer (BC), PMRT after BR may affect cosmetic outcomes and may compromise the original goal of improving quality of life (QoL). With the lack of practical guidelines, it seems essential to work on a consensus and provide some "expert agreements" to offer patients the best option for PMRT after BR.

Impact of the COVID-19 pandemic on clinical presentation, treatments, and outcomes of new breast cancer patients: A retrospective multicenter cohort study.

Background: The SARS CoV-2 pandemic disrupted healthcare systems. We compared the cancer stage for new breast cancers (BCs) before and during the pandemic.

Methods: We performed a retrospective multicenter cohort study on the data warehouse of Greater Paris University Hospitals (AP-HP).

Limited applicability and implementation of the international oncology treatments guidelines in low- and middle-income countries, an example from the Mediterranean area borders.

The quality of cancer care in the modern era is based on a precise diagnosis and personalized therapy according to patients and their disease based on validated guidelines with a high level of evidence. During cancer patients' management, the objective is first to make an accurate diagnosis and then offer the best treatment, validated beforehand in a multidisciplinary board meeting, with the best benefit/risk ratio. In the context of many low- and middle-income countries, the limited available means do not allow an adequate offer, resulting in non-optimal patients' care.

Quality assurance program and early toxicities in the phase III BONBIS randomized trial evaluating the role of a localized radiation boost in ductal carcinoma in situ.

Purpose: To describe the quality assurance (QA) program and early toxicities in the phase III randomized trial BONBIS (NCT00907868) on the role of a localized radiation boost in ductal carcinoma in situ (DCIS).

Materials And Methods: From November 2008 to July 2014, 2004 patients were randomized in arm A (only whole breast radiotherapy, WBRT) and arm B (WBRT + boost). The QA program involved 44 participant centers that performed the dummy run (DR).

Restaging the Biochemical Recurrence of Prostate Cancer with [Ga]Ga-PSMA-11 PET/CT: Diagnostic Performance and Impact on Patient Disease Management.

Background: Detection rates of [Ga]Ga-PSMA-11 PET/CT on the restaging of prostate cancer (PCa) patients presenting with biochemical recurrence (BCR) have been well documented, but its performance and impact on patient management have not been evaluated as extensively.

Methods: Retrospective analysis of PCa patients presenting with BCR and referred for [Ga]Ga-PSMA-11 PET/CT. Pathological foci were classified according to six anatomical sites and evaluated with a three-point scale according to the uptake intensity.

Radiation Therapy Delivery Challenges in Older Patients During Coronavirus Disease 2019 Pandemic.

Purpose: The management of older patients in radiation therapy (RT) departments has been challenging in the context of the Coronavirus Disease 2019 (COVID-19) outbreak. We report our experience of RT adapted schedules or strategy changes in older patients during the COVID-19 pandemic.

Methods And Materials: Patients aged ≥75 years were recruited during weekly chart rounds.

Axillary nodal irradiation practice in the sentinel lymph node biopsy era: Comparison of the contemporary available 3D and IMRT techniques.

Objective: Our study aimed to compare regional node coverage and doses to the organ at risk (OAR) using conventional technique (CT) "AMAROS" (AT) intensity-modulated radiation therapy (IMRT) techniques in patients receiving regional nodal irradiation (RNI) for breast cancer (BC).

Methods: We included 30 consecutive patients with BC who received RNI including axillary nodes. Two independent and blinded dosimetric RNI plans were generated for all patients.

A Wake-Up Call for Routine Morbidity and Mortality Review Meeting Procedures as Part of a Quality Governance Programs in Radiation Therapy Departments: Results of the PROUST Survey.

Purpose: Morbidity and mortality review (MMR) meetings in radiation therapy (RT) departments aim to monitor radiation-induced toxicities and identify potential factors that may be correlated with their development and severity, particularly treatment planning errors. The aims of the Prospective Registration of Morbidity and Mortality, Individual Radiosensitivity and Radiation Technique (PROUST) survey were to make an inventory of existing MMR procedures and to describe their procedures.

Methods And Materials: The link to the web-based questionnaire of the PROUST survey was sent to 351 radiation oncologists working at 172 centers.

Daily Practice Management of pT1a-b pN0 Breast Carcinoma: A Prospective French ODISSEE Cohort Study.

Background: Most breast cancer (BC) tumors ≤10 mm have an excellent prognosis. The subgroups with a higher risk for distant recurrence requiring adjuvant systemic therapy are not precisely defined in current international guidelines.

Patients And Methods: The OBSERVATOIRE DES PETITS CANCERS DU SEIN HER2 +/- (ODISSEE) study was a prospective, multicenter, cohort study that aimed to describe the daily adjuvant management and outcome of 616 patients with unifocal, invasive pT1a-b pN0 nonmetastatic BC who underwent surgery.

HER2 status for prognosis and prediction of treatment efficacy in adenocarcinomas: a review.

The past few years have seen flourish new biologic parameters for cancer prognosis that are revolutionizing therapeutic strategies. HER-2 is in this perspective a striking example, as it is now a key element for the care of 15-20% of breast cancer. HER-2 overexpression has first been reported as a prognostic factor before its consideration as a main parameter to predict treatment efficacy.
