Triumph Over Butchery: Guest Editorial for Indian Journal of Surgical Oncology.

While once considered "butchery," thyroid cancer surgery is now considered a safe surgery in the setting of the increasing incidence of thyroid nodules. Several changes in the approach to patients and advancements in technology have paved the way for the technical feasibility of thyroid surgery. International guidelines have enabled a personalized, and less invasive approach to patients and thus reducing the morbidity attributed tumors from potential injury to the recurrent laryngeal nerve or long-term thyroid hormone replacement- particularly for papillary microcarcinomas.

Impact of prior cholecystectomy on diagnosis and outcomes of choledochal cyst resection in adults.

Introduction: The diagnosis of choledochal cysts in the adult population is complicated by the expected physiologic dilation of the common bile duct after cholecystectomy. We aimed to compare patients who underwent choledochal cyst resection based on cholecystectomy status.

Methods: A retrospective analysis was conducted of patients who underwent choledochal cyst resection between 1/1/1998-12/31/2021.

The utility of axial imaging among selected patients in the early postoperative period after pancreatectomy.

Background: Postoperative computed tomography imaging has been shown to play an important role in avoiding failure-to-rescue. We sought to examine the impact of the timing of such imaging studies on outcomes after pancreatectomy.

Methods: Patients who underwent pancreatic resection at our institution from 2017 to 2022 were reviewed retrospectively to identify those undergoing computed tomography for any indication before discharge.

Approach to postpancreatectomy care Impacts outcomes: Retrospective Validation of the PORSCH trial.

Background: In the recent PORSCH trial, a three-part postpancreatectomy care algorithm was employed with a near 50 ​% reduction in mortality. We hypothesized that clinical care congruent with this protocol would correlate with better outcomes in our patients.

Methods: Real-world postoperative care was compared to the pathway described by the PORSCH trial and patients were assigned into groups based on congruence with its recommendations.

Characteristics and malignancy rates of adult patients diagnosed with choledochal cyst in the West: a systematic review.

Background: The approach to patients with choledochal cysts (CCs) remains varied and subject to institutional practices. Owing to the rarity of the disease, the optimal treatment remains poorly defined, particularly in the adult population. This study aimed to review the literature on adult patients with CCs to evaluate trends of diagnosis and management in Western countries.

Novel prognostic nomogram for predicting recurrence-free survival in medullary thyroid carcinoma.

Aims: Recently, there have been attempts to improve prognostication and therefore better guide treatment for patients with medullary thyroid carcinoma (MTC). In 2022, the International MTC Grading System (IMTCGS) was developed and validated using a multi-institutional cohort of 327 patients. The aim of the current study was to build upon the findings of the IMTCGS to develop and validate a prognostic nomogram to predict recurrence-free survival (RFS) in MTC.

Morbidity and Outcomes of Primary Tumor Management in Patients with Widely Metastatic Well-Differentiated Small Bowel Neuroendocrine Tumors.

Background: The benefit of primary tumor resection in distant metastatic small bowel neuroendocrine tumors (SBNETs) is controversial, with treatment-based morbidity not well-defined. We aimed to determine the impact of primary tumor resection on development of disease-specific complications in patients with metastatic well-differentiated SBNETs.

Patients And Methods: A retrospective analysis was performed of patients diagnosed with metastatic well-differentiated jejunal/ileal SBNETs at a single tertiary care cancer center from 1980 to 2016.

Minimally Invasive Robotic Techniques for Hepatocellular Carcinoma Resection: How I Do It.

The adoption of minimally invasive techniques for hepatocellular resection has progressively increased in North America. Cumulative evidence has demonstrated improved surgical outcomes in patients who undergo minimally invasive hepatectomy. In this review, the authors' approach and methodology to minimally invasive robotic liver resection for hepatocellular carcinoma is discussed.

Association of the Genomic Profile of Medullary Thyroid Carcinoma with Tumor Characteristics and Clinical Outcomes in an International Multicenter Study.

The prognostic importance of and mutations and their relationship to clinicopathologic parameters and outcomes in medullary thyroid carcinoma (MTC) need to be clarified. A multicenter retrospective cohort study was performed utilizing data from 290 patients with MTC. The molecular profile was determined and associations were examined with clinicopathologic data and outcomes.

Cooperative Genomic Lesions in HRAS-Mutant Cancers Predict Resistance to Farnesyltransferase Inhibitors.

The clinical development of farnesyltransferase inhibitors (FTI) for -mutant tumors showed mixed responses dependent on cancer type. Co-occurring mutations may affect response. We aimed to uncover cooperative genetic events specific to -mutant tumors and study their effect on FTI sensitivity.

Tumor Grade Predicts for Calcitonin Doubling Times and Disease-Specific Outcomes After Resection of Medullary Thyroid Carcinoma.

Tumor grade is a new validated prognostic factor for medullary thyroid cancer (MTC). Calcitonin doubling time can predict MTC recurrence. We aimed to describe the association of tumor grade with calcitonin doubling and its effect on disease-specific outcomes times after resection.

National evaluation of patterns and predictors of underuse of multimodal therapy for high-risk extremity soft tissue sarcoma.

Background: Treatment of high-risk extremity soft tissue sarcomas remains widely varied. Despite growing support for a multimodal approach for treatment of these rare and aggressive neoplasms, its dissemination remains underused. This national study aimed to evaluate variations in treatment patterns and uncover factors predictive of underuse of multimodal therapy in high-risk extremity soft tissue sarcomas.

International Medullary Thyroid Carcinoma Grading System: A Validated Grading System for Medullary Thyroid Carcinoma.

Purpose: Medullary thyroid carcinoma (MTC) is an aggressive neuroendocrine tumor (NET) arising from the calcitonin-producing C cells. Unlike other NETs, there is no widely accepted pathologic grading scheme. In 2020, two groups separately developed slightly different schemes (the Memorial Sloan Kettering Cancer Center and Sydney grade) on the basis of proliferative activity (mitotic index and/or Ki67 proliferative index) and tumor necrosis.

Incidental Polyp on Colectomy Specimen is Linked with Higher Odds of Polyp on Interval Colonoscopy.

Background: Incidentally found polyps on surgical pathology after colectomy is an underreported phenomenon, and management guidelines are lacking. Elucidation of the significance of incidental polyps is needed to determine if post-operative endoscopic surveillance modification is warranted. We sought to determine the relationship between incidental polyp on colectomy specimen and findings on post-operative colonoscopy.

Prophylactic Lateral Neck Dissection for Medullary Thyroid Carcinoma is not Associated with Improved Survival.

Background: Patients with medullary thyroid carcinoma (MTC) often receive lateral lymph node dissection with total thyroidectomy when calcitonin levels are elevated, even in the absence of structural disease, but the effect of this intervention on disease-specific outcomes is not known.

Patients And Methods: We retrospectively reviewed patients from 1986 to 2017 who underwent thyroidectomy with curative intent for MTC at our institution. The association of disease-specific survival and clinicopathologic features was examined using univariate and multivariate Cox regression.

Acute abdomen caused by a large solitary jejunal diverticulum that induced a midgut volvulus. Report of a case.

Background: Jejunal diverticula are a rare subtype of false diverticula found in the gastrointestinal tract. When present, they are usually multiple, in the proximal jejunum and asymptomatic. Rarely, they can cause acute complications that can develop into an acute abdomen requiring surgical intervention.

Radical excision for retroperitoneal soft tissue sarcoma: A national propensity-matched outcomes analysis.

Background: Given the rarity of retroperitoneal soft tissue sarcoma, few studies have assessed if radical excision of retroperitoneal soft tissue sarcoma with adjacent organs improves survival outcomes. This propensity score-matched study aimed to evaluate the impact of radical excision versus resection of tumor alone.

Methods: The National Cancer Database 2004 to 2015 was used to assess short- and long-term outcomes of resection of tumor alone versus radical excision (tumor plus ≥1 adjacent organs) via 1:1 propensity-matched analyses.

Inhibition of T-Type calcium channels in mEC layer II stellate neurons reduces neuronal hyperexcitability associated with epilepsy.

Temporal lobe epilepsy (TLE) is a form of adult epilepsy involving the entorhinal cortex (EC). Layer II neurons of the medial EC (mEC) are spared and become hyperexcitable in TLE. Studies have suggested a role for T-type calcium channels (T-type Ca channels) in facilitating increases in neuronal activity associated with TLE within the hippocampus.

Pro-excitatory alterations in sodium channel activity facilitate subiculum neuron hyperexcitability in temporal lobe epilepsy.

Temporal lobe epilepsy (TLE) is a common form of adult epilepsy involving the limbic structures of the temporal lobe. Subiculum neurons act to provide a major output from the hippocampus and consist of a large population of endogenously bursting excitatory neurons. In TLE, subiculum neurons are largely spared, become hyperexcitable and show spontaneous epileptiform activity.

Evidence for a role of Nav1.6 in facilitating increases in neuronal hyperexcitability during epileptogenesis.

During epileptogenesis a series of molecular and cellular events occur, culminating in an increase in neuronal excitability, leading to seizure initiation. The entorhinal cortex has been implicated in the generation of epileptic seizures in both humans and animal models of temporal lobe epilepsy. This hyperexcitability is due, in part, to proexcitatory changes in ion channel activity.

Temporal lobe epilepsy induces intrinsic alterations in Na channel gating in layer II medial entorhinal cortex neurons.

Temporal lobe epilepsy (TLE) is the most common form of adult epilepsy involving the limbic structures of the temporal lobe. Layer II neurons of the entorhinal cortex (EC) form the major excitatory input into the hippocampus via the perforant path and consist of non-stellate and stellate neurons. These neurons are spared and hyper-excitable in TLE.
