Jejunum free flap for head and neck reconstruction, a step-by-step surgical technique videos.

Circular pharyngolaryngectomy for oncologic resection requires a tubular reconstruction. Different options can be proposed to the patient: digestive free flap, fasciocutaneous flap, or musculocutaneous flap. The jejunum free flap is a tubular flap commonly used in esophageal and pharyngeal reconstruction with good functional outcomes and an acceptable rate of complications. Reconstruction with a jejunum free flap is an ideal choice. Patients at Gustave Roussy Institute (Villejuif, France) were offered a jejunum flap free flap for all circular pharyngolaryngectomies. The surgical technique is explained with a step-by-step video. The jejunum flap free flap has many advantages in circular pharyngolaryngectomy. This video article explains surgical steps for other teams.

Oncological Outcomes of Concurrent Chemoradiotherapy and Surgical Treatment for Patients With T3 Hypopharyngeal Cancer: A Single-Center Retrospective Analysis.

Background Since the larynx and pharynx are vital for respiration, swallowing, and speech, chemoradiotherapy (CRT) has been widely applied for T3 hypopharyngeal cancer (HPC) as an organ-preserving treatment. However, CRT can lead to severe late adverse events such as dysphagia and aspiration pneumonia, especially in patients who have difficulty swallowing and/or aspiration at the time of initial diagnosis. Patients and methods Between 2012 and 2020, 86 patients with T3 HPC treated with curative intent at Kobe University Hospital were included in this study. The average age was 69 years old, ranging from 43 to 89. Diseases were classified as Stage III in 29 patients, Stage IVA in 52 patients, and Stage IVB in five patients. Thirty-five (41%) patients were treated by CRT, and 51 (59%) patients were treated by surgery. Patients were followed up for at least two years, and the follow-up period ranged from four to 128 months (median: 45 months). Results Three-year progression-free survival (PFS) rates of patients treated by CRT and patients treated by surgery were 56.2% and 60.3%, respectively. Three-year disease-specific survival (DSS) rates of patients treated by CRT and surgically treated patients were 79.0% vs. 70.8%, respectively. Three-year overall survival (OS) rates of patients treated by CRT and surgically treated patients were 64.5% and 69.0%, respectively. Of note, a significant difference was observed between three-year DSS and three-year PFS (79.0% vs. 56.2%, p = 0.0014) in the patients treated by CRT but not in the patients treated by surgery. Conclusions No significant differences were observed between the PFS, DSS, and OS rates of patients treated by CRT and those of surgically treated patients. Locoregional recurrences after CRT were significantly successfully salvaged by surgical intervention. These results suggest that CRT can be applied as an alternative to surgery without reducing survival, especially for patients without severe clinical symptoms. Meticulous follow-up is mandatory for early detection of recurrence to salvage by surgery and for the management of late adverse events.

Salvage surgery following tyrosine kinase inhibitor treatment for advanced non-small cell lung cancer.

BACKGROUND: No standard therapy for non-small lung cancer patients that have acquired resistance to tyrosine kinase inhibitor (TKI) therapy has been established. Some can be effectively treated by salvage surgery, though indications for that procedure remain unclear. Reported here is the clinical course of a patient who experienced early post-operative distant metastases. CASE PRESENTATION: A 48-year-old woman without symptoms was referred to another hospital for abnormal chest radiography findings and diagnosed with adenocarcinoma of the left lower lobe (cT2aN3M1b, stage IVB; TNM staging 7th edition). Gene mutation analysis revealed positive for epidermal growth factor receptor exon 19 deletion. Afatinib treatment was started, resulting in partial response, though regrowth of the main tumor was noted 1.5 years later. Bronchoscopic re-biopsy findings revealed a T790M point mutation and afatinib was switched to osimertinib. At 1.5 years following the start of osimertinib administration, the primary tumor was found to have regrown again and stereotactic radiation therapy was administered. Findings at 3.5 years after osimertinib administration indicated that all lymph nodes and distant metastases, excluding the primary tumor, were well controlled, and the patient was referred to our hospital for salvage surgery. Osimertinib was discontinued, and a left lower lobectomy with a left lingular segmentectomy and pleural biopsy were performed. The patient was discharged following an uneventful postoperative course. Three days after discharge, glossodynia developed and examination findings revealed tongue metastasis. The symptoms improved following re-administration of osimertinib, though right adrenal gland metastasis appeared 8 months after surgery. Radiation therapy was performed for tongue and right adrenal gland metastases, and the patient was alive 1 year after salvage surgery without out-of-control lesion appearing after the radiation therapy under the administration of osimertinib. CONCLUSION: The present patient experienced multiple instances of systemic recurrence after undergoing salvage surgery. Experience with this case indicates that systemic therapy is essential for patients with distant metastatic lung cancer even following salvage surgery for the primary tumor.

Thoracoscopic salvage esophagectomy with prophylactic mediastinal lymph node dissection after definitive chemoradiotherapy for patients with esophageal cancer.

BACKGROUND: Salvage esophagectomy for residual tumor and localized relapses after definitive chemoradiotherapy (dCRT) for patients with esophageal cancer is associated with a high rate of postoperative complications and in-hospital mortality. In addition, there are many controversial issues associated with salvage esophagectomy, such as the acceptability of minimally invasive surgery and the need for prophylactic dissection of mediastinal lymph nodes. The aim of this study was to evaluate the safety and usefulness of thoracoscopic salvage esophagectomy with prophylactic mediastinal lymph node dissection. METHODS: The study included 31 patients who underwent thoracoscopic salvage esophagectomy with prophylactic mediastinal lymph node dissection after dCRT between 2013 and 2022 (salvage patients) and 610 nonsalvage patients who underwent conventional thoracoscopic esophagectomy during the same time period. RESULTS: Differences between the median ages and sexes of the 2 patient groups were not significant. The dominant location of tumors in the salvage patients was the upper thoracic esophagus. More salvage patients had clinical T4 disease. The salvage patients had a lower median number of retrieved mediastinal lymph nodes than the nonsalvage patients. The differences between the rates of R0, postoperative complications, and in-hospital deaths in the 2 patient groups were not significant. The 3-year overall survival (OS) rates for the salvage patients were 73%, with 3-year OS rates for R0 vs non-R0 of 81% vs 0%, p < 0.01 and pN0 vs pN1-3 of 89% vs 49%, p < 0.01. CONCLUSION: Regarding short-term outcomes, prophylactic mediastinal lymph node dissection for patients undergoing thoracoscopic salvage esophagectomy was as safe as prophylactic dissection for patients undergoing conventional thoracoscopic esophagectomy. R0 surgery and pN0 are important factors for long-term survival in patients undergoing thoracoscopic salvage esophagectomy.

Narrative review of immediate salvage for penile prosthesis infection.

Background and Objective: Implantation of a penile prosthesis is a reliable option for men with erectile dysfunction (ED) refractory to less invasive therapies. While the frequency of penile prosthesis infections have decreased, they remain a devastating complication. Herein we discuss why immediate salvage surgery is an essential technique for the management of implant infections. We will also describe the relevant advancements to this technique. Methods: We conducted a narrative review via computer based search of PubMed for all relevant articles on penile prosthesis infection management, including guidelines, case series, reviews, and expert opinions. Search terms used included: "inflatable penile prosthesis", "IPP", "penile prosthesis", "salvage", "treatment", "delayed", "immediate". Only English peer-reviewed publications were included. Key Content and Findings: Historically, patients who presented with penile prosthesis infections were exclusively managed with complete removal of the prosthesis without replacement. Although this strategy is safe, it hastens immediate ED and corporal fibrosis, resulting in loss of penile length and increased difficulty with subsequent prosthesis replacement. Previous case series have reported successful treatment of localized penile prosthesis infections with nonsurgical treatment, but the role of conservative treatment remains limited. The current standard of immediate salvage entails removal of the infected prosthesis and washout followed by immediate replacement with a new penile prosthesis. This technique has been demonstrated to be safe and effective, thus allowing patients to resume intercourse and maintain penile length. Conclusions: Immediate salvage surgery is safe and effective, and has emerged as the preferred strategy for the management of most patients with a penile prosthesis infection.

Overcoming barriers to immediate penile implant salvage surgery: a narrative review.

Background and Objective: Since immediate salvage (IS) surgery for infected penile prosthesis (PP) was introduced nearly 30 years ago, an abundance of evidence has emerged in support of its use. IS remains underutilized by the modern urologist despite its distinct advantages. While some medical literature proposes reasons for the underuse of IS, no comprehensive review attempts to address the numerous factors limiting its implementation. Our objective is to analyze the barriers to IS surgery for infected PP with the goal of expanding utilization of this technique through a practical and standardized approach for treating urologists. Methods: A narrative review of available English, peer-reviewed, medical literature relevant to the barriers to IS was completed. Searches were expanded to include literature from surgical specialties in general if hypothesized barriers were incompletely described in available PP publications. Key Content and Findings: The major barriers that are likely contributing to the low rates of IS for PP surgery can be broadly classified into three major categories: institutional/systemic, medical/surgical, and patient preference. Institutional/systemically driven barriers include surgeon comfort with PP surgery, low national availability of urologists, inaccessibility of prosthetics or critical ancillary staff at the time of patient presentation and limited operating room (OR) access. Medical/surgical barriers primarily relate to reinfection fears, perceived contraindications to IS, and overall patient stability at the time of presentation. Patient preference factors inhibiting IS involve loss of trust in the medical team, psychosocial distress, dissatisfaction with the initial device prior to infection and anxiety regarding postoperative recovery. Many of the identified barriers can be overcome with increased surgical training, improved patient and surgeon understanding of PP infection, or precautionary planning. Conclusions: Of the factors that contribute to low utilization of IS, many are misunderstood or unknown. Recognition of these barriers may equip urologists to provide better care to patients with prosthesis infection.

Salvage surgery for pouch-related complication after ileal pouch-anal anastomosis: a report of two cases.

BACKGROUND: Pouch-related complications (PRCs), such as pelvic abscesses and perianal complex fistulas, can occur after ileal pouch-anal anastomosis (IPAA) in ulcerative colitis (UC). They are often difficult to treat and require salvage surgery. We report two cases of PRC associated with fistulas. CASE PRESENTATION: First case: A 38-year-old man was diagnosed with UC at age 26 years. Four months after the diagnosis of UC, the patient underwent hand-assisted laparoscopic restorative proctocolectomy, IPAA, and ileostomy for acute fulminant UC. Two years after the closure of the ileostomy, the patient developed a perianal abscess and underwent ileostomy reconstruction. He was referred to our department at 35 years of age, because his symptoms did not improve despite repeated seton drainage of a complicated perineal fistula. We diagnosed PRC with a pelvic abscess and complicated pouch fistula and performed salvage surgery. This diagnosis was revised to Crohn's disease. SECOND CASE: A 50-year-old man was diagnosed with UC at age 18 years and was administered high doses of steroids; however, his symptoms did not improve. He underwent restorative proctocolectomy, IPAA, and ileostomy at another hospital. The ileostomy was closed, and his condition stabilized thereafter. At 35 years of age, perianal pain developed, and he was diagnosed with a complicated pouch-perineal fistula. A fistula was observed near the staple line of the ileal end closure on the head side of the pouch. Reconstruction of the ileostomy and seton drainage were performed; however, his symptoms did not improve, and he was referred to our hospital. We diagnosed PRC with a pelvic abscess and a complicated pouch fistula and performed salvage surgery. The resected specimen showed strictures in two locations: at the oral site of the afferent limb (at the pouch) and at the IPAA. Both patients returned to society and are currently outpatients. CONCLUSIONS: We encountered two cases of PRC after IPAA that did not improve with seton drainage or ileostomy. Pouch resection was performed after considering the patient's quality of life and reintegration into society.

Salvage surgery for recurrent transdiaphragmatic thymoma in a patient not eligible for chemotherapy.

The recurrence rate following thymoma surgery has been reported to be as high as 29%. In cases of localized recurrence, complete resection can result in prolonged patient survival. However, surgery is rarely considered in cases of invasive recurrent thymomas with high disease burden. Here, we present the case of a woman with type B2 thymoma (Masaoka-Koga stage IVa) treated with surgery, chemotherapy, and radiotherapy. The disease recurred 6 years later, with invasion of the left lung and the 12th thoracic vertebra, as well as extension into the retroperitoneum. Due to the development of chemotherapy-associated toxicity, she underwent surgery with complete tumor resection and has remained free of disease at a 12-months follow-up. Radical surgery for recurrent invasive thymoma extending through the diaphragm is a feasible and safe therapeutic option in highly selected patients who are not eligible for systemic treatments.

Treatment of the neck in residual/recurrent disease after chemoradiotherapy for advanced primary laryngeal cancer.

Concomitant chemoradiotherapy (CRT) is extensively used as primary organ preservation treatment for selected advanced laryngeal squamous cell carcinomas (LSCC). The oncologic outcomes of such regimens are comparable to those of total laryngectomy followed by adjuvant radiotherapy. However, the management of loco-regional recurrences after CRT remains a challenge, with salvage total laryngectomy being the only curative option. Furthermore, the decision whether to perform an elective neck dissection (END) in patients with rN0 necks, and the extent of the neck dissection in patients with rN + necks is still, a matter of debate. For rN0 patients, meta-analyses have reported occult metastasis rates ranging from 0 to 31 %, but no survival advantage for END. In addition, meta-analyses also showed a higher incidence of complications in patients who received an END. Therefore, END is not routinely recommended in addition to salvage laryngectomy. Although some evidence suggests a potential role of END for supraglottic and locally advanced cases, the decision to perform END should weigh benefits against potential complications. In rN + patients, several studies suggested that selective neck dissection (SND) is oncologically safe for patients with specific conditions: when lymph node metastases are not fixed and are absent at level IV or V. Super-selective neck dissection (SSND) may be an option when nodes are confined to one level. In conclusion, current evidence suggests that in rN0 necks routine END is not necessary and that in rN + necks with limited nodal recurrences SND or a SSND could be sufficient.

Biochemical Response of <0.1 ng/ml Predicts Therapy-free Survival of Prostate Cancer Patients following Prostate-specific Membrane Antigen-targeted Salvage Surgery.

BACKGROUND: In a subset of patients with oligorecurrent prostate cancer (PCa), salvage surgery with prostate-specific membrane antigen (PSMA) radioguided surgery (PSMA-RGS) seems to be of value. OBJECTIVE: To evaluate whether a lower level of postoperative prostate-specific antigen (PSA; <0.1 ng/ml) is predictive of therapy-free survival (TFS) following salvage PSMA-RGS. DESIGN, SETTING, AND PARTICIPANTS: This cohort study evaluated patients with biochemical recurrence after radical prostatectomy and oligorecurrent PCa on PSMA positron emission tomography treated with PSMA-RGS in three tertiary care centers (2014-2022). INTERVENTION: PSMA-RGS. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Postsalvage surgery PSA response was categorized as <0.1, 0.1-<0.2, or >0.2 ng/ml. Kaplan-Meier and multivariable Cox regression models evaluated TFS according to PSA response. RESULTS AND LIMITATIONS: Among 553 patients assessed, 522 (94%) had metastatic soft tissue lesions removed during PSMA-RGS. At 2-16 wk after PSMA-RGS, 192, 62, and 190 patients achieved PSA levels of <0.1, 0.1-<0.2, and >0.2 ng/ml, respectively. At 2 yr of follow-up, TFS rate was 81.1% versus 56.1% versus 43.1% (p < 0.001) for patients with PSA <0.1 versus 0.1-<0.2 versus >0.2 ng/ml. In multivariable analyses, PSA levels of 0.1-0.2 ng/ml (hazard ratio [HR]: 1.9, confidence interval [CI]: 1.1-3.1) and ≥0.2 ng/ml (HR: 3.2, CI: 2.2-4.6, p < 0.001) independently predicted the need for additional therapy after PSMA-RGS. The main limitation is the lack of a control group. CONCLUSIONS: For patients after salvage PSMA-RGS, a lower biochemical response (PSA <0.1 ng/ml) seems to predict longer TFS. This insight may help in counseling patients postoperatively as well as guiding the timely selection of additional therapy. PATIENT SUMMARY: We studied what happened to prostate cancer patients in three European centers who had salvage surgery using a special method called prostate-specific membrane antigen-targeted radioguidance. We found that patients who had low prostate-specific antigen levels soon after surgery were less likely to need further treatment for a longer time.

Limited prognostic role of routine serum markers (AP, CEA, LDH and NSE) in oligorecurrent prostate cancer patients undergoing PSMA-radioguided surgery.

INTRODUCTION: We evaluated the prognostic role of pre-salvage prostate-specific membrane antigen-radioguided surgery (PSMA-RGS) serum levels of alkaline phosphatase (AP), carcinoembryonic antigen (CEA), lactate dehydrogenase (LDH), and neuron-specific enolase (NSE). MATERIALS AND METHODS: Patients who consecutively underwent PSMA-RGS for prostate cancer (PCa) oligorecurrence between January 2019 and January 2022 were selected. Biomarkers were assessed one day before surgery. Cox regression and logistic regression models tested the relationship between biochemical recurrence-free survival (BFS), 6- and 12-month biochemical recurrence (BCR), and several independent variables, including biomarkers. RESULTS: 153 consecutive patients were analyzed. In the univariable Cox regression analysis, none of the biomarkers achieved predictor status (AP: hazard ratio [HR] = 1.03, 95% CI 0.99, 1.01; p = 0.19; CEA: HR = 1.73, 95% CI 0.94, 1.21; p = 0.34; LDH: HR = 1.01, 95% CI 1.00, 1.01; p = 0.05; NSE: HR = 1.02, 95% CI 0.98, 1.06; p = 0.39). The only independent predictor of BFS was the number of positive lesions on PSMA PET (HR = 1.17, 95% CI 1.02, 1.30; p = 0.03). The number of positive lesions was confirmed as independent predictor for BCR within 6 and 12 months (BCR < 6 months: odds ratio [OR] = 1.1, 95% CI 1.0, 1.3; p = 0.04; BCR < 12 months: OR = 1.1, 95% CI 1.0, 1.3; p = 0.04). CONCLUSION: The assessment of AP, CEA, LDH, and NSE before salvage PSMA-RGS showed no prognostic impact. Further studies are needed to identify possible predictors that will optimize patient selection for salvage PSMA-RGS.

Expandable endoprostheses in skeletally immature patients: Where we are.

Approximately 45 percent of malignant bone tumors are seen under the age of 16 and one of the important results of growth plate sacrification in patients with immature skeletons is limb inequality. Until the early 1990s, the treatment options for these patients were rotationplasty or amputation. Multimodal approaches that combine imaging, chemotherapy, and surgical techniques have enabled the development of limb-preserving methods with satisfactory results. In order to overcome inequality problems, expandable prostheses have been developed in the 1980s. Extendable endoprosthesis replacements have been improved over the years and are now an established and safe alternative. Noninvasive prostheses appear to be advantageous compared to minimally invasive expandable prostheses that require multiple surgical procedures, but the complication rate remains high. Therefore, although expandable prostheses are not the definitive answer to the treatment of bone sarcomas in skeletally immature children, they are still a suitable interim choice until full adulthood is achieved. Due to reported high complication rates, the procedures require significant experience and are recommended for use only in specialized cancer centers.

Great Debates: Surgery or Watch and Wait After Total Neoadjuvant Therapy for Rectal Cancer.

Locally advanced rectal cancer has traditionally been treated with multimodal therapy including neoadjuvant chemoradiotherapy followed by surgical resection. More recent data suggests that in appropriate patients, total neoadjuvant treatment (TNT) makes it possible to adopt a "watch and wait" approach. Advocates for watch and wait argue that patients with a complete or near-complete clinical response to TNT have comparable overall and disease-free survival to their counterparts who undergo surgical resection, and also have a better quality of life, fewer complications, and potentially avoid a stoma. The dogma of surgery as regional curative intent therapy has been challenged by similar recurrence rates among those treated with total mesorectal excision (TME) and those treated with watch and wait. Furthermore, those who develop local recurrence in the watch and wait groups are equally salvageable, either by surgery, brachytherapy, or chemotherapy. While watch and wait is not appropriate in all patients, this manuscript highlights the benefits and drawbacks of both therapeutic modalities.

Assessing Circulating Tumour DNA (ctDNA) as a Biomarker for Anal Cancer Management: A Systematic Review.

This systematic review investigates the potential of circulating tumour DNA (ctDNA) as a predictive biomarker in the management and prognosis of squamous cell carcinoma of the anal canal (SCCA). PubMed, EMBASE, and Cochrane Central Registry of Controlled Trials were searched until 7 January 2024. Selection criteria included research articles exploring ctDNA in the context of anal cancer treatment response, recurrence risk assessment, and consideration of salvage surgery. A total of eight studies were therefore included in the final review, examining a total of 628 patients. These studies focused on three main themes: SCCA diagnosis and staging, treatment response, and patient outcomes. Significant heterogeneity was observed in terms of patient cohort, study methodology, and ctDNA biomarkers. Four studies provided information on the sensitivity of ctDNA biomarkers in SCCA, with a range of 82-100%. Seven studies noted a correlation between pre-treatment ctDNA levels and SCCA disease burden, suggesting that ctDNA could play a role as a biomarker for the staging of SCCA. Across all seven studies with paired pre- and post-treatment ctDNA samples, a trend was seen towards decreasing ctDNA levels post-treatment, with specific identification of a 'fast elimination' group who achieve undetectable ctDNA levels prior to the end of treatment and may be less likely to experience treatment failure. Residual ctDNA detection post-treatment was associated with poorer patient prognosis. This systematic review identifies the broad potential of ctDNA as a useful and decisive tool in the management of SCCA. Further analysis of ctDNA biomarkers that include larger patient cohorts is required in order to clearly evaluate their potential role in clinical decision-making processes.

An academic achievements visualization research since the 21st century: research on salvage surgery for head and neck cancer.

Background: Head and neck cancer is the 6th most common malignancy worldwide, and its incidence is still on the rise. The salvage surgery has been considered as an important treatment strategy for persistent or recurrent head and neck cancer. Therefore, we conducted a bibliometric analysis of salvage surgery for head and neck cancer since the 21st century. Methods: The literature about salvage surgery of head and neck cancer in Web of Science was searched. CiteSpace and VOSviewer were used to analyze main countries, institutions, authors, journals, subject hotspots, trends, frontiers, etc. Results: A total of 987 papers have been published since the 21st century. These publications were written by 705 authors from 425 institutions in 54 countries. The United States published 311 papers in this field and ranked first. Head & Neck was the most widely published journal. The main keyword clustering included terms such as #0 stereotactic radiotherapy (2012); #1 randomized multicenter (2007); #2 salvage surgery (2004); #3 functional outcomes (2014); #4 transoral robotic surgery (2013); #5 neck high-resolution computed tomography (2010); #6 complications (2008); #7 image guidance (2019). The current research frontiers that have been sustained are "recurrent", "risk factors", and "reirradiation". Conclusion: The current situation of the salvage surgery for head and neck cancer in clinical treatments and basic scientific research were summarized, providing new perspectives for the development of salvage surgery for head and neck cancer in the future.

Metal Ion Release in Cancer Patients Following Megaprosthesis Salvage Surgery.

BACKGROUND: Megaprostheses contain many more modular components than conventional total hip and knee arthroplasty, which may lead to higher serum levels of metal ions. The aim of this study was to determine serum concentrations of titanium, chromium, and cobalt ions in cancer patients after limb salvage surgery with a megaprosthesis. METHODS: A retrospective, descriptive cohort analysis consisting of patients who underwent cancer-related limb salvage surgery with a megaprosthesis at our hospital between 2010 and 2020 was conducted. Baseline and follow-up data were extracted from clinical and surgical records. Blood samples were prospectively obtained. Descriptive statistics were used for the analysis. RESULTS: A total of 71 patients underwent limb salvage surgery during the study period. Of these, 22 (10 women, 12 men) were included in the study. The mean age was 52 years (range, 21 to 80). Most cases (n = 16; 72.7%) involved the femur. Most patients (n = 14, 63.6%) underwent total knee megaprosthesis surgery. Implant revision surgery was required in 45% of cases (n = 10), with a mean interval of 4.32 years between the initial and revision surgeries. The mean follow-up time after revision surgery was 4.05 years. High levels of chromium were observed in 22.7% of patients (n = 5). High cobalt levels were found in 68.2% (n = 15) of patients, with toxic levels in 9.1% (n = 2). Titanium levels were high in 77.3% (n = 17) of cases and toxic in 22.7% (n = 5). Postoperative chemotherapy was significantly associated with titanium levels (P = .017). No correlation was observed between metal ion levels and time from primary or revision surgery or time from the first to revision surgery. CONCLUSIONS: This study shows that cancer-related limb salvage surgery with megaprosthesis is associated with metal ion levels that exceed established safe thresholds. Compared to conventional hip arthroplasty, a higher proportion of the patients in this cohort presented elevated levels of metal ions. LEVEL OF EVIDENCE: III.

Outcomes and pathologic response of primary lung cancer treated with tyrosine kinase inhibitor/immune checkpoint inhibitor before salvage surgery.

PURPOSE: Advances in primary lung cancer drug therapy have extended patients' survival, including patients with stage IV disease. This study assessed the safety and effectiveness of salvage surgery following tyrosine kinase inhibitor (TKI) or immune checkpoint inhibitor (ICI) therapy in primary lung cancer. METHODS: A retrospective chart review was conducted of 2050 primary lung cancer surgeries performed at our institution between 2012 and 2022. The study included patients who underwent salvage surgery for unresectable lesions that became resectable or localized residual lesions after treatment. We investigated patients' clinicopathological characteristics, therapeutic responses, and survival outcomes. RESULTS: We identified eight cases of salvage surgery after TKI treatment and eight cases after ICI treatment. Five patients experienced early recurrence after surgery; however, the long-term outcome in the post-TKI group was favorable, with a median overall survival (OS) of 66 (range: 28-80) months. Postoperative recurrence was confined to local lymph node recurrence in one patient in the post-ICI group. Despite the relatively short observation period, the long-term prognosis remained promising, with a median OS of 18.7 (range: 9.7-55.8) months. CONCLUSIONS: Salvage surgery after TKI or ICI treatment can be safely performed, and the OS may be favorable.

Impact of Level of Surgery on the Functional Outcomes in Patients with Lower Extremity Bone Tumors Undergoing Amputation Versus Limb Salvage Surgery.

Limb salvage surgery is the preferred treatment for bone tumors in the current surgical practice. The aim of this study was to compare the functional outcomes between amputation and limb salvage surgery based on the level of surgery at two levels: knee and hip. A single institutional analysis of 137 patients with lower extremity bone tumors was done between 2014 and 2020. Eighty-seven patients treated with amputation were compared with 50 patients treated with limb salvage surgery based on following variables: age, gender, histology, anatomic site, and MSTS score. The mean MSTS scores were fairly better in patients who underwent surgery at knee level compared to those who underwent surgery at hip level. The mean MSTS score at 1-year follow-up was 22.0 in amputation group compared to 22.4 in limb salvage group, whereas at 2-year follow-up was 24.1 in amputation group compared to 25.1 in limb salvage group. At knee level, functional outcomes were similar after amputation and limb salvage. At hip level, patients undergoing amputation had poorer MSTS scores compared to limb salvage surgery at 2-year follow-up (p = 0.04). The functional outcomes for patients undergoing surgery at knee level were similar irrespective of type of surgery. At longer follow-up, patients undergoing amputation at hip level had a poorer functional outcome compared to limb salvage surgery. Although limb salvage was associated with similar MSTS scores when compared with amputation, it produced a better functional outcome especially for proximally located tumors.

Salvage extended surgery after immune-checkpoint inhibitor treatment for advanced non-small cell lung cancer.

PURPOSE: We evaluated the surgical outcomes of salvage extended surgery after definitive medical treatment with an immune-checkpoint inhibitor (ICI) for locally advanced or unresectable non-small-cell lung cancer (NSCLC). METHODS: The subjects of this single-center retrospective analysis were 14 patients who underwent salvage surgery after ICI treatment between May, 2017 and April, 2023 at our institute. We reviewed the comprehensive surgical outcomes, including operative procedures, intraoperative findings, and postoperative morbidities. Overall survival (OS) was calculated using a Kaplan-Meier estimation. RESULTS: The initial clinical stage before medical treatment (c-stage) was stage III in eight patients, stage IV in five patients, and one patient had postoperative lung cancer recurrence. The indications for surgery were as follows: local control for relapse or residual tumor in ten patients and discontinuation of systemic therapy because of treatment-related complications in four patients. The surgical modes were segmentectomy (n = 1), lobectomy (n = 4), bilobectomy (n = 3), pneumonectomy (n = 6), and bronchoplasty (n = 7). Grade 3 or higher postoperative morbidities were observed in six patients, including only one case of 90-day mortality. CONCLUSIONS: Our series demonstrated that the surgical outcome of salvage extended surgery after ICI therapy may be positive with careful selection of the procedure and indication.

Redo IPAA for long rectal cuff syndrome after ileoanal pouch for inflammatory bowel disease.

ABTRACT: BACKGROUND: When constructing an ileal pouch-anal anastomosis (IPAA), the rectal cuff should ideally be 1-2 cm long to avoid subsequent complications. METHODS: We identified patients from our IBD center who underwent redo IPAA for a long rectal cuff. Long rectal cuff syndrome (LRCS) was defined as a symptomatic rectal cuff ≥ 4 cm. RESULTS: Forty patients met the inclusion criteria: 42.5% female, median age at redo surgery 42.5 years. The presentation was ulcerative proctitis in 77.5% of the cases and outlet obstruction in 22.5%. The index pouch was laparoscopically performed in 18 patients (45%). The median rectal cuff length was 6 cm. The pouch was repaired in 16 (40%) cases, whereas 24 (60%) required the creation of a neo-pouch. At the final pathology, the rectal cuff showed chronic active colitis in 38 (90%) cases. After a median follow-up of 34.5 (IQR 12-109) months, pouch failure occurred in 9 (22.5%) cases. The pouch survival rate was 78% at 3 years. Data on the quality of life were available for 11 (27.5%) patients at a median of 75 months after redo surgery. The median QoL score (0-1) was 0.7 (0.4-0.9). CONCLUSION: LRCS, a potentially avoidable complication, presents uniformly with symptoms of ulcerative proctitis or stricture. Redo IPAA was restorative for the majority.
