Outcome Squares Integrating Efficacy and Safety, as Applied to Functioning Pituitary Adenoma Surgery.

CONTEXT: Transsphenoidal surgery is standard care in the treatment of hormone-secreting pituitary adenomas. Current clinician-reported surgical outcome measures are one-dimensional, typically focusing primarily on complete or partial resection, and secondarily on complication rates. However, outcomes are best reflected by the delicate balance of efficacy and complications at patient level. OBJECTIVE: This study proposes a novel way to classify and report outcomes, integrating efficacy and safety at the patient level. METHODS: Retrospective chart review of all pure endoscopic transsphenoidal surgical procedures for acromegaly, Cushing's disease, and prolactinoma between 2010 and 2018 in a single tertiary referral center. We present our results in a classic (remission and complications separate) and in a novel outcome square integrating both outcomes, focusing on intended and adverse effects (long-term complications). This resulted in 4 outcome groups, ranging from good to poor. We use this approach to present these outcomes for several subgroups. RESULTS: A total of 198 surgical procedures were included (44 reoperations). Remission was achieved in 127 operations (64%). Good outcome was observed after 121 (61%), and poor outcome after 6 (3%) operations. When intended effect of surgery was applied (instead of remission), good outcome as intended was achieved after 148 of 198 surgeries (75%) and poor outcome after 4 (2%). CONCLUSION: Quality of a surgical intervention can be presented in 4 simple categories, integrating both efficacy and safety with flexibility to adapt to the individualized situation at patient, disease, and surgical strategy and to the outcome of interest.

How we do it: Changes in thyroid and salivary gland surgery since 1989: who's doing it and what are they doing?

Keypoints * The aim of this study was to identify changes in the provision of parotid, submandibular and thyroid gland surgery between surgical specialties since 1989, as well as changes in surgical practice. * Data from the Department of Health's Hospital Episode Statistics (HES) was extracted from 1989/1990 and 2003/2004 records by operation and surgical specialty in England. * The data reveals a considerable decline in the amount of parotid and submandibular surgery performed by General surgeons; with the majority of this surgery currently being performed by ENT surgeons, and to a lesser extent, Oral and Maxillo-Facial surgeons. * Thyroid surgery has undergone less radical change, with General surgeons continuing to perform the majority of cases; however, an increasing proportion is now provided by ENT surgeons. * There also seems to be changes in the types of thyroid operation being performed; with large increases in total thyroidectomy and reductions in subtotal thyroidectomies.

[The impact of the extent and time of operation on the survival in patients with differentiated thyroid carcinoma (DTC)]. / Znaczenie zakresu i czasu leczenia operacyjnego u chorych na zróznicowane raki tarczycy.

INTRODUCTION: To analyze the impact of time and extent of operation on overall and disease-free survival in patients with differentiated thyroid carcinoma (DTC). MATERIAL AND METHODS: Retrospective analysis of 1235 DTC patients, a representative probe of patients diagnosed or treated between 1986 to 1998 was performed. 277 patients were staged T1M0 and 958 ones staged > T1M0. 10-year outcomes were analyzed by Kaplan-Meier survival curves and Cox proportional-hazard model. RESULTS: The T1M0 patients were characterized by the best overall and disease-free survival independently of the time and the extent of operation (98% and 96% respectively); in > T1M0 group the survival was better in patients who were treated by total thyroidectomy (94% and 68% respectively) than in patients treated by non-total thyroidectomy (78% and 47% respectively). In patients treated by completion of total thyroidectomy delayed more than 1 year post cancer diagnosis the incidence of carcinoma in postoperative pathological material was twice as high in comparison to the group in whom total thyroidectomy was performed within the first year of therapy (p = 0.000). CONCLUSIONS: 1. In differentiated thyroid carcinoma the prognosis is related to the extent of operation only in patients staged more than T1M0. 2. A delay > 12 months in completion surgery in patients with differentiated thyroid cancer (tumors > 1 cm of diameter) significantly increases the risk of progression of multifocal disease in thyroid remnants.
