Author/s: 
Laura Boucai, Mark Zafereo, Maria E Cabanillas

Importance: Approximately 43 720 new cases of thyroid carcinoma are expected to be diagnosed in 2023 in the US. Five-year relative survival is approximately 98.5%. This review summarizes current evidence regarding pathophysiology, diagnosis, and management of early-stage and advanced thyroid cancer.

Observations: Papillary thyroid cancer accounts for approximately 84% of all thyroid cancers. Papillary, follicular (≈4%), and oncocytic (≈2%) forms arise from thyroid follicular cells and are termed well-differentiated thyroid cancer. Aggressive forms of follicular cell-derived thyroid cancer are poorly differentiated thyroid cancer (≈5%) and anaplastic thyroid cancer (≈1%). Medullary thyroid cancer (≈4%) arises from parafollicular C cells. Most cases of well-differentiated thyroid cancer are asymptomatic and detected during physical examination or incidentally found on diagnostic imaging studies. For microcarcinomas (≤1 cm), observation without surgical resection can be considered. For tumors larger than 1 cm with or without lymph node metastases, surgery with or without radioactive iodine is curative in most cases. Surgical resection is the preferred approach for patients with recurrent locoregional disease. For metastatic disease, surgical resection or stereotactic body irradiation is favored over systemic therapy (eg, lenvatinib, dabrafenib). Antiangiogenic multikinase inhibitors (eg, sorafenib, lenvatinib, cabozantinib) are approved for thyroid cancer that does not respond to radioactive iodine, with response rates 12% to 65%. Targeted therapies such as dabrafenib and selpercatinib are directed to genetic mutations (BRAF, RET, NTRK, MEK) that give rise to thyroid cancer and are used in patients with advanced thyroid carcinoma.

Conclusions: Approximately 44 000 new cases of thyroid cancer are diagnosed each year in the US, with a 5-year relative survival of 98.5%. Surgery is curative in most cases of well-differentiated thyroid cancer. Radioactive iodine treatment after surgery improves overall survival in patients at high risk of recurrence. Antiangiogenic multikinase inhibitors and targeted therapies to genetic mutations that give rise to thyroid cancer are increasingly used in the treatment of metastatic disease.

Question: Among children who snore without frequent obstructive events, does early adenotonsillectomy compared with watchful waiting with supportive care improve neurodevelopment, behavior, or other symptoms at 12-month follow-up?

Findings: In this randomized clinical trial of 458 children with mild sleep-disordered breathing (SDB), adenotonsillectomy compared with watchful waiting resulted in no significant differences in executive function or attention at 12 months. The adenotonsillectomy group had improved quality of life, symptoms, behavior, and blood pressure, which were among the secondary outcomes measured.

Meaning: In children with mild SDB, adenotonsillectomy resulted in no statistically significant differences in changes in executive function or attention but led to improved secondary outcomes including symptoms, behavior, and blood pressure.

Perioperative Management of Anticoagulant and Antiplatelet Therapy

The management of patients who are receiving an anticoagulant or antiplatelet drug and require surgery or an invasive procedure is a common clinical problem encountered by a broad spectrum of health care professionals. This review provides an evidence-based but practical approach to common clinical scenarios involving patients who require an elective surgery/procedure and are receiving either a vitamin K antagonist, a direct oral anticoagulant, or single or dual antiplatelet therapy. This review also addresses the role of perioperative heparin bridging and the management of patients who are receiving an anticoagulant drug and need urgent surgery.

Long-term patient-reported outcomes are needed to inform treatment decisions for localized prostate cancer.

METHODS
Patient-reported outcomes of 1643 randomly assigned participants in the ProtecT (Prostate Testing for Cancer and Treatment) trial were evaluated to assess the functional and quality-of-life impacts of prostatectomy, radiotherapy with neoadjuvant androgen deprivation, and active monitoring. This article focuses on the outcomes of the randomly assigned participants from 7 to 12 years using mixed effects linear and logistic models.

RESULTS
Response rates exceeded 80% for most measures. Among the randomized groups over 7 to 12 years, generic quality-of-life scores were similar. Among those in the prostatectomy group, urinary leakage requiring pads occurred in 18 to 24% of patients over 7 to 12 years, compared with 9 to 11% in the active monitoring group and 3 to 8% in the radiotherapy group. In the prostatectomy group, 18% reported erections sufficient for intercourse at 7 years, compared with 30% in the active monitoring and 27% in the radiotherapy groups; all converged to low levels of potency by year 12. Nocturia (voiding at least twice per night) occurred in 34% in the prostatectomy group compared with 48% in the radiotherapy group and 47% in the active monitoring group at 12 years. Fecal leakage affected 12% in the radiotherapy group compared with 6% in the other groups by year 12. The active monitoring group experienced gradual age-related declines in sexual and urinary function, avoiding radical treatment effects unless they changed management.

CONCLUSIONS
ProtecT provides robust evidence about continued impacts of treatments in the long term. These data allow patients newly diagnosed with localized prostate cancer and their clinicians to assess the trade-offs between treatment harms and benefits and enable better informed and prudent treatment decisions.

Background: This study aims to compare conservative versus surgical management for patients with full-thickness RC tear in terms of clinical and structural outcomes at 1 and 2 years of follow-up.

Methods: A comprehensive search of CENTRAL, MEDLINE, EMBASE, CINAHL, Google Scholar and reference lists of retrieved articles was performed since the inception of each database until August 2020. According to the Cochrane Handbook for Systematic Reviews of Interventions, two independent authors screened all suitable studies for the inclusion, extracted data and assessed risk of bias. Only randomised controlled trials comparing conservative and surgical management of full-thickness RC tear in adults were included. The primary outcome measure was the effectiveness of each treatment in terms of Constant-Murley score (CMS) and VAS pain score at different time points. The secondary outcome was the integrity of the repaired tendon evaluated on postoperative MRI at different time points. The GRADE guidelines were used to assess the critical appraisal status and quality of evidence.

Results: A total of six articles met the inclusion criteria. The average value of CMS score at 12 months of follow-up was 77.6 ± 14.4 in the surgery group and 72.8 ± 16.5 in the conservative group, without statistically significant differences between the groups. Similar results were demonstrated at 24 months of follow-up. The mean of VAS pain score at 12 months of follow-up was 1.4 ± 1.6 in the surgery group and 2.4 ± 1.9 in the conservative group. Quantitative synthesis showed better results in favour of the surgical group in terms of VAS pain score one year after surgery (- 1.08, 95% CI - 1.58 to - 0.58; P < 0.001).

Conclusions: At a 2-year follow-up, shoulder function evaluated in terms of CMS was not significantly improved. Further high-quality level-I randomised controlled trials at longer term follow-up are needed to evaluate whether surgical and conservative treatment provide comparable long-term results.

Preoperative Evaluation Before Noncardiac Surgery

Bierle, DM, Raslau, D, Regan, DW, Sundsted, KK, Mauck, K.F.

The medical complexity of surgical patients is increasing and medical specialties are frequently asked to assist with perioperative management surgical patients. Effective pre-anesthetic medical evaluations are a valuable tool in providing high-value, patient-centered surgical care and should systematically address risk assessment and identify areas for risk modification. This review outlines a structured approach to the pre-anesthetic medical evaluation, focusing on the asymptomatic patient. It discusses the evidence supporting the use of perioperative risk calculation tools and focused preoperative testing. We also introduce important key topics that will be explored in greater detail in upcoming reviews in this series.

How Will Treating My Early-Stage Prostate Cancer Affect My Quality of Life?

Author/s:

Early-stage prostate cancer can be treated in different ways. The three main ways are active surveillance, surgery, and radiotherapy. Active surveillance means having your prostate checked every few months to make sure the cancer is not spreading. Surgery would take out the prostate, and radiotherapy uses high-energy rays to kill cancer cells in the prostate.

Two recent PCORI-funded studies compare the effects of these choices on the quality of life for men with early-stage prostate cancer. These studies looked at three effects treatment might have on a man’s quality of life. These are problems having sex, urinary problems, and bowel problems.

Current Treatments for Localized Prostate Cancer and Symptom-Related Quality of Life

Author/s: 
Patient-Centered Outcomes Research Institute

Given the evidence of high 5- and 10-year survivorship rates for localized prostate cancer, the effect of treatment on symptom-related quality of life is an important consideration for men choosing among available treatment options. Two PCORI-funded studies published in the March 21, 2017 issue of JAMA compare the impact of current treatments on symptom-related quality of life for men with localized prostate cancer. Quality of life scores refer to symptoms, how much men were bothered by symptoms, or a combination of the two. The studies looked at observed outcomes from a combined total of 3,600 men for periods of two and three years following treatment. This evidence offers information that can help patients make treatment decisions.
