The Laser Probe, The iKnife and The Cutting Edge of Surgery

If the thought of going under the knife fills you with fear, be reassured. No longer is surgery the brutal and hazardous experience faced by our ancestors. Thanks to wonders such as laparoscopy, robotic solutions, and, more recently, the iKnife and the laser probe, surgical intervention is getting safer all the time. Archaeologists believe that people have been carrying out surgery for up to 11,000 years. Cranial surgery, known as trephination, probably dates back to the Neolithic era. It involved drilling a hole in the skull of a living person. Speculation suggests it was done to cure disorders such as convulsions, fractures, headaches, and infections. The Ancient Egyptians used the same operation for "letting out" headaches and migraine. From 1812 onward, the New England Journal of Medicine offers accounts of procedures that would now be considered gruesome, such as passing a hook through a man's pupil during the removal of a cataract, and using leeches for bloodletting. Pioneers of their time, both surgeons and patients displayed remarkable courage. Leap from there to the present, and you have minimally invasive surgery where even a heart transplant is now relatively routine. From January 1988 to July 2016, 64,055 cardiac transplants have taken place in the United States, according to the United Network for Organ Sharing (UNOS). Advances in minimally invasive surgery In 1987, a French gynecologist performed the first recognized laparoscopic surgery to re...

CONCLUSION: This is the first case to our knowledge describing both such lesions in one patient and the first case describing the use of 2-(3-{1-carboxy-5-[(6-[18F]fluoro-pyridine-3-carbonyl)-amino]-pentyl}-ureido)-pentanedioic acid (18F-DCFPyL)-PSMA PET/CT to detect IPAS. Furthermore we highlight the value of nuclear medicine diagnostic work up in complex cases. PMID: 30006647 [PubMed - as supplied by publisher]

CONCLUSION: Our results from this totally original study indicated that radioactive isotope 125I labeled to caerin peptide 1.9 may be used to treat breast cancer while at the same time the response to treatment may be monitored by simultaneous imaging.

CONCLUSION: A method of tumor size determination, using PHL on 18F-FDG PET/CT, showed more linear relationship and smaller size differences with pathology than MRI (average 0.6 vs. 1.9cm). It provides sufficient reliability and reproducibility for measuring tumor size in breast cancer. PMID: 30006644 [PubMed - as supplied by publisher]

Abstract Breast-conserving surgery (BCS) followed by radiation therapy is the current standard of care for early stage breast cancer. Successful BCS necessitates complete tumor resection with clear margins at the pathologic assessment of the specimen ("no ink on tumor"). The presence of positive margins warrants additional surgery to obtain negative final margins, which has significant physical, psychological, and financial implications for the patient. The challenge lies in developing accurate real-time intraoperative margin assessment techniques to minimize the presence of "ink on tumor" and ...

Management of the Axilla in the Patient with Breast Cancer. Surg Clin North Am. 2018 Aug;98(4):747-760 Authors: Park KU, Caudle A Abstract Evaluation of the axillary lymph nodes is critical in the management of breast cancer because it is a key predictor of survival outcome. Surgeons must not only be able to perform sentinel lymph node dissection with high accuracy but also understand the implications of the results. Management of clinically node-negative and node-positive cases can vary significantly, as described in this review. With emerging data, management of the axilla in breast cancer will...

Abstract Ductal carcinoma in situ has been stable in incidence for a decade and has an excellent prognosis. Breast conservation therapy is safe and effective for most patients. Adjuvant whole breast radiation therapy is recommended to reduce the risk of local recurrence. Accelerated partial breast irradiation is a promising alternative to decrease toxicity and improve cosmetic results. Adjuvant hormonal therapy can reduce local recurrence, but should be used cautiously. Future directions in management include developing predictive tools for guidance for use of adjuvant therapy and selecting low-risk patients ...

Abstract New emerging breast imaging techniques have shown great promise in breast cancer screening, evaluation of extent of disease, and response to neoadjuvant therapy. Tomosynthesis, allows 3-dimensional imaging of the breast, and increases breast cancer detection. Fast abbreviated MRI has reduced time and costs associated with traditional breast MRI while maintaining cancer detection. Diffusion-weighted imaging is a functional MRI technique that does not require contrast and has shown potential in screening, lesion characterization and also evaluation of treatment response. New image-guided preoperative locali...

Abstract The American Joint Committee on Cancer staging system has evolved in response to improved imaging, refined surgical techniques, enhanced pathologic evaluation, and greater understanding of tumor biology. The 8th edition has introduced clinical and pathologic prognostic stages for breast cancer that incorporate biologic variables (grade, estrogen/progesterone receptor status, HER2 status, multigene panels) with TNM categories that define the anatomic stage. The prognostic staging system facilitates more refined stratification than the anatomic stage with respect to survival and is an important advance that...

Abstract As more genetic information becomes available to inform breast cancer treatment, screening, and risk-reduction approaches, clinicians must become more knowledgeable about possible genetic testing and prevention strategies, including outcomes, benefits, risks, and limitations. The aim of this article is to define and distinguish high- and moderate-risk breast cancer predisposition genes, summarize the clinical recommendations that may be considered based on the identification of pathogenic variants (mutations) in these genes, and indications for risk-reducing and contralateral prophylactic mastectomy. ...
