Radiation Segmentectomy for Hepatocellular Carcinoma.

The application of trans-arterial radioembolization (TARE) with Yttrium-90, historically a palliative treatment option for patients with advanced hepatocellular carcinoma (HCC), is evolving. Radiation segmentectomy (RADSEG), the segmental delivery of an ablative radiation dose, is a treatment option for patients with earlier-stage HCC. This review presents an in-depth exploration of RADSEG, emphasizing its technical considerations, dosimetry advancements, and patient selection. The integration of RADSEG into the Barcelona Clinic Liver Cancer (BCLC) paradigm will be highlighted. RADSEG outcomes concerning safety and efficacy will be explored and compared with traditional locoregional cancer treatments like trans-arterial chemoembolization (TACE), percutaneous thermal ablation, and surgical resection, with an eye on future directions and considerations.

Update on Locoregional Therapies for Liver Cancer: Radiation Segmentectomy.

Over 900,000 people worldwide were diagnosed with liver cancer in 2022 alone, with hepatocellular carcinoma (HCC) accounting for 75-85% of cases. Treatment for HCC includes some combination of systemic therapies, surgery, liver transplantation, ablation, and intra-arterial therapies with transarterial chemoembolization (TACE) or transarterial radioembolization (TARE). Currently, the Barcelona Clinic Liver Cancer (BCLC) guidelines have acknowledged liver transplantation, surgical resection, and thermal ablation as curative therapies in very early to early stage HCC (BCLC-0 and BCLC-A). While these modalities are the preferred curative treatments for a very early to early stage disease, there are challenges associated with these options, such as organ availability and patient eligibility. Current data shows the role of radiation segmentectomy as a curative therapeutic option for very early to early stage HCC that is unresectable and not amenable to ablation. As future data continues to elucidate the ability for radiation segmentectomy to achieve complete pathologic necrosis, the goal is for the BCLC staging model to acknowledge its role as a curative treatment in this patient population and incorporate it into the ever-evolving guidelines.

Below-the-Knee Stents and Scaffolds: A Comprehensive Review.

Below-the-knee intervention of chronic limb-threatening ischemia is an area of increasing interest. Due to lower morbidity and possibly better clinical outcomes, endovascular techniques have become increasingly important in this patient population many of who have limited surgical options. This article serves as a review of existing stent and scaffolding devices utilized for infrapopliteal disease. The authors will additionally discuss current indications and review studies that are investigating novel materials used in treating infrapopliteal arterial disease.

Nationwide Bibliometric Analysis of Integrated Plastic Surgery Program Directors.

Studies have linked bibliometric indices with the academic level of plastic surgeons, but this relationship has not been explored with residency program directors (PDs). As teachers of the next generation, PDs' academic performance is an important component of residency program success. We sought to identify distinguishing characteristics of integrated plastic surgery programs, focusing on their PD bibliometric indices. Methods: We identified plastic surgery programs based on 2021 Doximity reputation and research output rankings, respectively, and then divided them into four quartiles (Q1-Q4). PD academic history and bibliometric indices (h-index, the number of publications, and citations) were collected through Doximity profiles and program websites: PubMed, Scopus, Google Scholar, American Society of Plastic Surgeons, and Accreditation Council for Graduate Medical Education. Results: Eighty-four programs were identified. There was a significant positive relationship between h-index, the number of publications, and type of research with reputation ranking (P < 0.05). After adjusting for years of experience post-training, h-index (OR = 1.24; P < 0.001) and the number of publications (OR = 1.05, P < 0.001) were significantly associated with reputation ranking. There was a statistically significant relationship between PD research fellowship completion and research output ranking (P < 0.01). After adjusting for years of experience post-training, h-index (OR = 1.05; P = 0.047) and the number of publications (OR = 1.01; P = 0.04) were significantly associated with research output ranking. Conclusion: Higher ranked programs tend to have PDs who have a strong record of scholarly activity, as evidenced by certain bibliometric indices.

Chemoembolization Plus Ablation: Current Status.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide. The treatment landscape for HCC has evolved significantly over the past decade, with several modalities available to treat various stages of disease. The Barcelona Clinic Liver Cancer (BCLC) system provides a foundation for treatment guidance. However, given the complex nature of HCC, a more nuanced approach is often required, especially for lesions sized between 3 and 5 cm. This review aims to analyze the available treatments for early-stage HCC lesions between 3 and 5 cm, with a focus on the therapeutic potential and efficacy of transarterial chemoembolization (TACE)-ablation. Additional therapies including TACE, ablation, transarterial radioembolization, and surgical resection are also reviewed and compared with TACE-ablation. TACE-ablation is a viable therapeutic option for early-stage HCC lesions between 3 and 5 cm. Surgical resection remains the gold standard. Although recent studies suggest radiation segmentectomy may be a curative approach for this patient population, further studies are needed to compare the relative efficacies between TACE-ablation and radiation segmentectomy.

A clinicopathologic examination of myxofibrosarcoma. Do surgical margins significantly affect local recurrence rates in this infiltrative sarcoma subtype?

BACKGROUND AND OBJECTIVES: Myxofibrosarcoma (MFS) is an aggressive soft tissue tumor with an unpredictable recurrence pattern. We sought to (a) determine whether margin status in MFS is correlated to rates of local recurrence (LR) and (b) identify demographic and treatment variables associated with disease-related outcomes in this population. METHODS: This retrospective study identified 42 surgically treated patients with MFS over 10 years at a single institution. Patient demographics, tumor characteristics, intraoperative variables, and disease-related outcomes were recorded. RESULTS: Thirty-three (83%) patients had negative surgical margins and seven (18%) had positive margins. Four of 32 patients (13%) with negative margins developed subsequent LR compared to six of seven (86%) patients with positive margins (p < .001). Three patients (75%) with metastatic disease were deceased at the end of the study, while five (15%) without metastasis were deceased (p = .024). CONCLUSIONS: Positive margin procedures for MFS were associated with LR. However, negative surgical margins demonstrated a relatively high rate of LR compared to other soft tissue sarcoma subtypes. Furthermore, though MFS tends to locally recur and have a propensity for distant metastasis, patients are observed to have a higher probability of death from other causes.

PROMIS® scores in operative metastatic bone disease patients: A multicenter, prospective study.

BACKGROUND: The prevalence of metastatic bone disease (MBD) grows each year as treatments improve. Little has been published about functional and pain outcomes in this group after surgery. Patient-Reported Outcomes Measurement Information System (PROMIS® ) can collect information, in just minutes, about patient's physical, mental, and social health. This study evaluated PROMIS® pain and functional scores in surgically treated patients with MBD. METHODS: Basic demographics and PROMIS® scores were recorded from a total of 13 patients at 9 periods of time over 6 months. RESULTS: The average change in physical function at week 1 was -2.5 (standard deviation [SD] = 5.4), at 2 weeks 1.7 (SD = 7.6), after 4 weeks 6.9 (SD = 10), after 6 weeks 6.4 (SD = 10.9), after 10 weeks 15.3 (SD = 3.1), and after 3 months 8.6 (SD = 7.6). The average change in pain inference at week 1 was -1.2 (SD = 7.3), at 2 weeks -2.1 (SD = 9.5), after 4 weeks -12.6 (SD = 4.5), after 6 weeks -8.3 (SD = 10.2), after 10 weeks -16.6 (SD = 4.3), and after 3 months -11.4 (SD = 8.2). CONCLUSIONS: PROMIS® provides a feasible means to collect data in this population. Trends of improved function and decreased pain were seen after surgery. Continuing this study will hopefully elucidate more insight into the surgical treatment of MBD.
