A Breast 3D model as a possible tool for non-invasive tumour localization in breast surgery
Background: For tumour location and surgical planning physicians need to convert 2-D information into a 3D approach. Wire guided surgery is the most common method for preoperative localization of breast cancer lesions. Other localization methods can also be used, such as radioactive seeds, carbon tattooing or ultrasound guided clips, but they are all invasive procedures. In this work, we aimed at building an individualized 3D digital breast model integrating the breast torso and tumor location through MRI/3D fusion algorithms to help in pre-operative tumour location without the use of invasive procedures.
CONCLUSION: The probability of nodal positivity after neoadjuvant chemotherapy was less than 3 per cent in patients with TNBC or HER2-positive disease who achieved a breast rCR on MRI. These patients could be included in trials investigating the omission of sentinel node biopsy after neoadjuvant chemotherapy. PMID: 33031572 [PubMed - as supplied by publisher]
Background: Ultrasound-guided locoregional nerve blocks have been recently used in patients undergoing surgery for breast cancer. In particular, Paravetrebral block (PVB) and newer Pectoralis nerve (PECS) blocks can be used with the main aims of improving postoperative pain control and reducing use of opioids during general anesthesia. In this comparative study we investigated the effects of PVB and PECS in intraoperative opioid consumption, postoperative opioid consumption, postoperative nausea and vomiting (PONV), operative time, and post-operative hospital stay.
CONCLUSION: Our study found that Korean females aged 40-49 years with US-detected breast cancer showed better DFS than those with mammography-detected breast cancer. However, there were no statistically significant differences in OS. PMID: 32901456 [PubMed - as supplied by publisher]
CONCLUSION: The female predominance of diseases of the thyroid and breast makes difficult the separation of an expected association with a casual linkageThe relationship between the co-occurrence of breast and thyroid cancer remains controversial and inconclusive.

CONCLUSIONS: Mean seroma formation at postoperative 24th hour was 112.5±53.3 mL in the control group and 74.5±47.4 mL in the TPVB group (p=0.022). NRS scores were similar between two groups (p=0.367) at postoperative 24th hour but mean morphine consumption at postoperative 24th hour was 5.6±4 mg in the TPBV group, and 16.6±6.9 mg in the control group (p
ConclusionsInvestigation using stringent MRI criteria and ultrasound-guided biopsy could accurately predict patients with pCR after NAC. A larger prospective clinical trial evaluating the clinical safety of breast surgery omission after NAC in selected patients will be conducted based on these findings.
CONCLUSION: The present study provides a patient-specific prediction model for evaluating nodal tumour burden in patients with clinically node-positive breast cancer. PMID: 32492194 [PubMed - as supplied by publisher]
Boguševičius A Abstract Background and objectives: With improved diagnostic means of early breast cancer, the percentage of cases with metastasis in axillary lymph nodes has decreased from 50%-75% to 15%-30%. Lymphadenectomy and sentinel lymph node biopsy are not treatment procedures, as they aim at axillary nodal staging in breast cancer. Being surgical interventions, they can lead to various complications. Therefore, recently much attention has been paid to the identification of non-invasive methods for axillary nodal staging. In many countries, ultrasound is a first-line method to evaluate axillary lym...
Barranger E Abstract OBJECTIVES: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients. MATERIALS AND METHODS: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images. We analyzed the number of additional breast biopsies and axillary lymph node fine needle aspiration (...
l;koğlu UH Abstract STUDY OBJECTIVE: Erector spinae plane (ESP) block is a novel regional anesthesia technique and gaining importance for postoperative pain management. Since it was first described, the clinicians wonder if this new simple technique can replace paravertebral block (PVB). We aimed to compare the postoperative analgesic effect of ESP block and PVB with a control group in breast surgeries. DESIGN: Randomized controlled trial. SETTING: Operating room. PATIENTS: Seventy-five ASA I-II patients aged 25-65, who were scheduled to go under elective unilateral breast surgery for breast cancer...
