Søreide K, Stättner S, Hallet J. Surgery as a Principle and Technical Consideration for Primary Tumor Resection of Small Bowel Neuroendocrine Tumors. Ann Surg Oncol 2024; 31:1125-1137. [PMID: 38006527 PMCID: PMC10761444 DOI: 10.1245/s10434-023-14610-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Accepted: 10/31/2023] [Indexed: 11/27/2023]
Abstract
Small bowel neuroendocrine tumors (SB-NETs) are increasingly identified and have become the most frequent entity among small bowel tumors. An increasing incidence, a high prevalence, and a prolonged survival with optimal modern multidisciplinary management makes SB-NETs a unique set of tumors to consider for surgical oncologists. The major goals of surgical treatment in the setting of SB-NET include control of tumor volume, control of endocrine secretion, and prevention of locoregional complications. Key considerations include assessment of multifocality and resection of mesenteric nodal masses with the use of mesenteric-sparing approaches and acceptance of R1 margins if necessary to clear disease while avoiding short bowel syndrome. A description through eight steps for consideration is presented to allow for systematic surgical planning and execution of resection. Moreover, some controversies and evolving considerations to the surgical principles and technical procedures remain. The role of primary tumor resection in the presence of (unresectable) liver metastasis is still unclear. Reports of feasibility of minimally invasive surgery are emerging, with undetermined selection criteria for appropriateness or long-term outcomes. Resection of SB-NETs should be considered in all patients fit for surgery and should follow principles to achieve surgical oncological control that is appropriate for the stage and tumor burden, considering the age and comorbidity of the individual patient.

[PMID: 38144202 PMCID: PMC10749088 DOI: 10.7717/peerj.16687] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 11/26/2023] [Indexed: 12/26/2023] Open
Abstract
Objective To explore the potential value of magnetic resonance (MR) and computed tomography (CT) enterography in the diagnosis of small intestinal tumor (SIT). Methods Articles reporting on the diagnosis of SIT by MR and CT enterography deposited in Chinese and foreign literature databases were identified and evaluated using the quality assessment of diagnostic accuracy studies (QUADAS). The diagnostic data extracted from the articles were adopted for meta-analysis using Meta-disc 1.40 software. Analysis was undertaken to compare the sensitivity, specificity, positive and negative likelihood ratios, and the diagnostic odds ratio (DOR) of MR and CT enterography in the diagnosis of SIT. The diagnostic values of the two imaging methods were analyzed by summary receiver operating characteristic (SROC) curves. The meta-analysis was registered at INPLASY (202380053). Results A total of eight articles, including 551 cases of SIT were included in this analysis. The pooled sensitivity and specificity of MR enterography were 0.92 (95% CI [0.89-0.95]) and 0.81 (95% CI [0.74-0.86]), respectively, whilst CT enterography had a sensitivity of 0.93 (95% CI [0.90-0.95]) and a specificity of 0.83 (95% CI [0.76-0.88]). For MR enterography, the combined positive likelihood ratio was 4.90 (95% CI [3.50-6.70]), the combined negative likelihood ratio was 0.10 (95% CI [0.07-0.14]), and the area under the receiver operating characteristic curve (AUROC) was 0.940. For CT enterography, the corresponding values were 5.40 (95% CI [3.90-7.40]), 0.08 (95% CI [0.06-0.12]), and 0.950, respectively. When the pretest probability for MR was assumed to be 50%, the posterior probabilities for positive and negative results were calculated as 83% and 9%, respectively. For CT enterography with a pretest probability of 50%, the posterior probabilities of positive and negative results were 84% and 8%, respectively. Conclusion MR and CT enterography have high accuracy in the diagnosis of SIT and have a valuable role in the diagnosis and management of these tumors.

[PMID: 37974218 PMCID: PMC10652443 DOI: 10.1186/s12920-023-01736-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 11/10/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND Small bowel cancer (SBC) is a very rare solid malignancy. Consequently, compared with other malignant gastrointestinal tumors, our knowledge regarding SBC, specifically its molecular attributes, remains limited. Herein, we aim to provide an overview of the gene characteristics of Chinese patients with SBC, We particularly focus on elucidating the genetic intricacies that differentiate SBC patients whose primary tumors originate in distinct anatomical regions within the small bowel. METHODS During the period ranging from February 2018 to December 2022, a total of 298 tumor samples were consecutively collected from Chinese patients diagnosed with small bowel cancer.. Next-generation sequencing (NGS) was performed to detect gene mutation, assess microsatellite instability (MSI), and evaluate tumor mutational burden (TMB). Additionally,, IHC was used to analyze the level of PD-L1 expression within the samples. RESULTS The outcomes of the next-generation sequencing (NGS) unveiled the predominant gene mutations observed in Chinese patients with small bowel cancer (SBC). The top ten gene mutations identified were as follows: TP53 (53%), KRAS (51%), APC (31%), SMAD4 (19%), VEGFA (15%), CDKN2A (15%), RAC1 (15%), LRP1B (14%), MGMT (14%, CD74 (13%). Subsequent analysis revealed disparities in the gene landscape between the cohort in this study and that of the Memorial Sloan Kettering Cancer Center (MSKCC), Notably, distinguishable mutational frequencies were identified in several genes, including ERBB2, FBXW7, PIK3CA, etc. which exhibited contrasting presence in both this cohort and the MSKCC cohort.. Furthermore, we noticed variations in the frequency of gene mutations among SBC patients depending on the specific anatomical site where the tumors originated within the small bowel. In addition, the distribution of patients with high microsatellite instability (MSI-H) and tumor mutational burden (TMB) levels varied among SBC patients with tumors originating from the duodenum, jejunum, and ileum. CONCLUSION Chinese patients with small bowel cancer exhibited a distinct genetic profile in comparison to other populations, highlighting a unique genetic landscape. Furthermore, noticeable disparities in the genetic landscape were observed between patients with cancer situated in the duodenum and those with cancer affecting other regions of the small bowel, this suggests that these patients should be treated differently.

An Accessible Laparoscope for Surgery in Low- and Middle- Income Countries. Ann Biomed Eng 2021; 49:1657-1669. [PMID: 33686617 DOI: 10.1007/s10439-020-02707-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Accepted: 12/04/2020] [Indexed: 01/11/2023]
Abstract
Laparoscopic surgery is the standard of care in high-income countries for many procedures in the chest and abdomen. It avoids large incisions by using a tiny camera and fine instruments manipulated through keyhole incisions, but it is generally unavailable in low- and middle-income countries (LMICs) due to the high cost of installment, lack of qualified maintenance personnel, unreliable electricity, and shortage of consumable items. Patients in LMICs would benefit from laparoscopic surgery, as advantages include decreased pain, improved recovery time, fewer wound infections, and shorter hospital stays. To address this need, we developed an accessible laparoscopic system, called the ReadyView laparoscope for use in LMICs. The device includes an integrated camera and LED light source that can be displayed on any monitor. The ReadyView laparoscope was evaluated with standard optical imaging targets to determine its performance against a state-of-the-art commercial laparoscope. The ReadyView laparoscope has a comparable resolving power, lens distortion, field of view, depth of field, and color reproduction accuracy to a commercially available endoscope, particularly at shorter, commonly-used working distances (3-5 cm). Additionally, the ReadyView has a cooler temperature profile, decreasing the risk for tissue injury and operating room fires. The ReadyView features a waterproof design, enabling sterilization by submersion, as commonly performed in LMICs. A custom desktop software was developed to view the video on a laptop computer with a frame rate greater than 30 frames per second and to white balance the image, which is critical for clinical use. The ReadyView laparoscope is capable of providing the image quality and overall performance needed for laparoscopic surgery. This portable low-cost system is well suited to increase access to laparoscopic surgery in LMICs.

Lee SC. Minimally invasive surgery with adenocarcinoma of jejunum diagnosed pathologically before surgery: A case report. Int J Surg Case Rep 2021; 79:354-357. [PMID: 33508617 PMCID: PMC7841214 DOI: 10.1016/j.ijscr.2021.01.061] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 01/14/2021] [Accepted: 01/15/2021] [Indexed: 12/25/2022] Open
Abstract
Adenocarcinoma of jejunum is a very rare malignant tumor worldwide. Small intestine cancer is difficult to diagnose histologically before surgery, and whether it is diagnosed before surgery has an important influence on the surgical method. Multidisciplinary treatment was conducted to diagnose small intestine cancer and determine treatment options, which is a global trend. In this case, the preoperative balloon endoscopy was used to diagnose small intestine cancer histologically, as well as the location of the lesion, so that the operation could be performed by laparoscopy.
Introduction and importance We report a rare case of a patient diagnosed with adenocarcinoma of the jejunum. Presentation of case The patient was a 58-year-old female patient who was tested for vomiting and dyspeptic symptoms at a local hospital and visited the hospital due to suspected small bowel obstruction. CT enteroscopy performed at our clinic revealed “progression of focal wall thickening in small bowel with proximal bowel dilatation”, and it was necessary to differentiate between malignant and infectious lesions. Balloon enteroscopy was planned for endoscopic observation up to the small bowel. The biopsy result was confirmed as adenocarcinoma with moderated differentiated. The patient underwent small bowel resection and anastomosis using standard laparoscopic surgery. Jejunum resection was performed by securing a safety margin of 10 cm or more, and sufficient LN dissection was also performed. The patient was discharged from the hospital without any specific complications, and as a result of pathology examination, it was confirmed as a stage 2 high risk group, and further treatment is in progress. Clinical discussion There are few reports of patients diagnosed with adenocarcinoma of the jejunum through symptoms of obstruction of the small intestine. Conclusions We report on a case of laparoscopic surgery for a rare jejunal cancer confirmed histologically before surgery.

[PMID: 33010797 DOI: 10.1002/rcs.2178] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 09/28/2020] [Accepted: 09/29/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Oesophageal benign to borderline tumours are rare entities, and their optimal treatment strategy remains controversial. Surgical robotic enucleation is an option to optimize their management. METHODS We prospectively collected data on seven consecutive oesophageal benign to borderline tumours operated robotically over a 4-year period. Patient baseline characteristics, perioperative outcomes and medium-term follow-ups were reviewed and analysed retrospectively. RESULTS Two patients underwent a robotic oesophagectomy and five underwent a simple enucleation. These last were the objective of the final analysis. Median operative time was 150 min. Neither deaths nor postoperative complications occurred. Median oral feeding started on postoperative day 3.5. The median postoperative stay was 5 days. Final histopathology confirmed two gastrointestinal stromal tumours, two leiomyomas and one simple cyst. CONCLUSIONS Robotic enucleation of oesophageal benign to borderline tumours is a feasible procedure in a dedicated oesophageal unit, with optimal perioperative outcomes in a small series of cases with limited follow-up.
