My name is Rodrigo Arrangoiz I am a breast surgeon/ thyroid surgeon / parathyroid surgeon / head and neck surgeon / surgical oncologist that works at Center for Advanced Surgical Oncology in Miami, Florida. I was trained as a surgeon at Michigan State University from (2005 to 2010) where I was a chief resident in 2010. My surgical oncology and head and neck training was performed at the Fox Chase Cancer Center in Philadelphia from 2010 to 2012. At the same time I underwent a masters in science (Clinical research for health professionals) at the University of Drexel. Through the International Federation of Head and Neck Societies / Memorial Sloan Kettering Cancer Center I performed a two year head and neck surgery and oncology / endocrine fellowship that ended in 2016.

  - Abstract:
    - Objective:
      - To determine the impact of tumor biology on rates of breast-conserving surgery and pathologic complete response (pCR) after neoadjuvant chemotherapy.
    - Summary Background Data:
      - The impact of tumor biology on the rate of breast-conserving surgery after neoadjuvant chemotherapy has not been well studied.
    - Methods:
      - They used data from ACOSOG Z1071, a prospective, multicenter study assessing sentinel node surgery after neoadjuvant chemotherapy in patients presenting with node-positive breast cancer from 2009 through 2011, to determine rates of breast-conserving surgery and pCR after chemotherapy by approximated biologic subtype.
    - Results:
      - Of the 756 patients enrolled on Z1071, 694 had findings available from pathologic review of breast and axillary specimens from surgery after chemotherapy.
      - Approximated subtype was triple-negative in 170 (24.5%) patients, HER2-positive in 207 (29.8%), and hormone- receptor-positive, HER2-negative in 317 (45.7%).
      - Patient age and clinical tumor and nodal stage at presentation did not differ across subtypes.
      - Rates of breast-conserving surgery were significantly higher in patients with triple-negative (46.8%) and HER2-positive tumors (43.0%) than in those with hormone-receptor-positive, HER2-negative tumors (34.5%) (P = 0.019).
      - Rates of pCR in both the breast and axilla were 38.2% in triple-negative, 45.4% in HER2-positive, and 11.4% in hormone-receptor-positive, HER2-negative disease (P < 0.0001).
      - Rates of pCR in the breast only and the axilla only exhibited similar differences across tumor subtypes.
    - Conclusions:
      - Patients with triple-negative and HER2-positive breast cancers have the highest rates of breast-conserving surgery and pCR after neoadjuvant chemotherapy:
        
        Patients with these subtypes are most likely to be candidates for less invasive surgical approaches after chemotherapy.

Does microscopic positive tumor margin in papillary thyroid cancer really matter?

Does microscopic positive tumor margin in papillary thyroid cancer really matter?

Kyorim Back, Seo Ki Kim, Young Jun Chai, Jung-Han Kim, Jun-Ho Choe, Jee Soo Kim

https://doi.org/10.1016/j.surg.2019.07.021

Background

The clinical impact of microscopically positive tumor margin in papillary thyroid cancer is not well studied. The aim of this study is to evaluate the clinical importance of a microscopically positive margin for recurrence in papillary thyroid cancer patients and to examine whether recurrence and recurrence-free survival were affected by the location of the positive margin—anterior or posterior.

Methods

We conducted a retrospective cohort study at a single institution. From January 1997 to June 2015,6,293 papillary thyroid cancer patients who underwent total thyroidectomy with or without neck dissection (central and/or lateral) at the Thyroid Cancer Center of Samsung Medical Center (Seoul, South Korea) were included in the analyses.

Results

Of the 6,293 papillary thyroid cancer patients, an operative margin was microscopically involved in 313 (5.0%) on final pathologic report. The mean follow-up time was 77.5 months, and locoregional recurrence was observed in 244 (3.9%) patients. The presence of a microscopically positive margin did not increase the risk of locoregional recurrence (adjusted hazard ratio = 1.079, P = .140) after adjustment for other statistically significant factors in the Cox proportional hazard model. In addition, posterior positive margin was not a risk factor for locoregional recurrence as well (adjusted hazard ratio = 1.24, P = .672). In a propensity score–matching analysis, a microscopically positive margin did not increase the risk of locoregional recurrence.

Conclusion

Microscopic involvement of the operative margin in papillary thyroid cancer patients, whether anteriorly or posteriorly, does not appear be an independent prognostic factor in recurrence-free survival rates.

Rodrigo ARRANGOIZ MS, MD, FACS Nos Habla Sobre el Cancer de Tiroides

November 15, 2019November 15, 2019 Rodrigo Arrangoiz MS, MD, FACS, FSSO

👉El cáncer de tiroides diferenciado es un diagnóstico frecuente e incluye tumores malignos con un comportamiento clínico diverso.

👉Aunque el pronóstico en general es excelente, el tratamiento conlleva riesgos sustanciales de morbilidad.

👉La estratificación del riesgo, basada en la patología, la biología del tumor, las evaluaciones bioquímicas y de imagen continuas, y las comorbilidades del paciente, ahora forman la base esencial del manejo del cáncer de tiroides diferenciado con un imperativo para proporcionar atención individualizada y apropiada para la enfermedad.

Rodrigo ARRANGOIZ MS, MD, FACS Thyroid Surgeon Talks About Differentiated Thyroid Cancer

November 15, 2019 Rodrigo Arrangoiz MS, MD, FACS, FSSO

👉Differentiated thyroid cancer is a frequent diagnosis and includes malignancies with diverse clinical behavior. Although overall prognosis is excellent, treatment carries substantial morbidity risks. Stratification of risk, based on pathology, tumor biology, ongoing biochemical and imaging assessments, and patient comorbidities, now forms the essential basis of DTC management with an imperative to provide care that is individualized and disease appropriate.
