About Jennifer L Marti, MD, FACS

Site Director, Breast & Endocrine Surgery, NYP/LMHPI for COMET trial at Cornell (active surveillance for DCIS)I am a surgeon specializing in breast surgical oncology and endocrine surgery. At Weill Cornell Medicine, I am proud of our multidisciplinary teams that provide the most advanced treatment options available in the New York area, to our patients with breast, thyroid, and parathyroid diseases. As a surgeon, my role is to help patients navigate this process and make the most informed decisions. I am a dual-fellowship trained surgeon, an Assistant Professor of Surgery at Weill Cornell Medicine and an Assistant Attending Surgeon at New York Presbyterian Hospital. Following medical school and general surgery residency at New York University School of Medicine, I completed advanced surgical fellowships at Memorial Sloan Kettering Cancer Center and Yale. My practice focuses on the treatment of benign and malignant disorders of the breast, thyroid, and parathyroid glands. These conditions include breast cancer, breast masses, abnormal mammograms and breast biopsies, a family history of breast cancer, thyroid nodules, thyroid cancer, hyperthyroidism (such as due to Graves disease), thyroid cancer, and hyperparathyroidism. I have expertise in all aspects of breast surgery (including newer techniques such as nipple-sparing mastectomy), and endocrine surgery (minimally invasive parathyroidectomy, thyroidectomy, modified radical neck dissection, carotid body tumor excision, and intraoperative nerve monitoring). In addition, we now offer patients with small papillary thyroid cancers the option of active surveillance, which can avoid unnecessary surgery. For patients with indeterminate thyroid nodules, I have published research on the optimal use of molecular assays such as Thyroseq and Afirma.I am also the PI for the COMET trial at Cornell. Some cancers, such as prostate cancer and thyroid cancer, occur in healthy persons and do not necessarily require treatment. At Cornell, women with a new diagnosis of Ductal Carcinoma In Situ (DCIS, also known as stage 0 breast cancer or ‘precancer’) identified on screening mammography may be candidates for a new approach of active surveillance (vigilant observation) instead of breast surgery. This approach is carried out as part of a national clinical trial called COMET (Comparison of Operative to Monitoring and Endocrine Therapy), which is offered at Cornell. For more information, call the office or visit am an active member of the New York Surgical Society, American Association of Endocrine Surgeons, American Society of Breast Surgeons, and the Society of Surgical Oncology.I am a regular speaker at national conferences and serve on several national society committees. I see patients at Weill Cornell on the upper east side at the David H Koch Center, and at Lower Manhattan Hospital downtown.NYP/Lower Manhattan Hospital 156 William Street 12th Floor New York, NY 10038 (646) 962-5213NYP/David H Koch Center 1283 York Avenue, 4th floor New York, NY 10065 (646) 962—5213
