Low-Dose Computed Tomography Screening in Relatives With a Family History of Lung Cancer.

INTRODUCTION: The role of a family history of lung cancer (LCFH) in screening using low-dose computed tomography (LDCT) has not been prospectively investigated with long-term follow-up. METHODS: A multicenter prospective study with up to three rounds of annual LDCT screening was conducted to determine the detection rate of lung cancer (LC) in asymptomatic first- or second-degree relatives of LCFH. RESULTS: From 2007 to 2011, there were 1102 participants enrolled, including 805 and 297 from simplex and multiplex families (MFs), respectively (54.2% women and 70.0% never-smokers). The last follow-up date was May 5, 2021. The overall LC detection rate was 4.5% (50 of 1102). The detection rate in MF was 9.4% (19 of 202) and 4.4% (4 of 91) in never-smokers and in those who smoked, respectively. The corresponding rates for simplex families were 3.7% (21 of 569) and 2.7% (6 of 223), respectively. Of these, 68.0% and 22.0% of cases with stage I and IV diseases, respectively. LC diagnoses within a 3-year interval from the initial screening tend to be younger, have a higher detection rate, and have stage I disease; thereafter, more stage III-IV disease and 66.7% (16 of 24) with negative or semipositive nodules in initial computed tomography scans. Within the 6-year interval, only maternal (modified rate ratio = 4.46, 95% confidence interval: 2.32-8.56) or maternal relative history of LC (modified rate ratio = 5.41, 95% confidence interval: 2.84-10.30) increased the risk of LC. CONCLUSIONS: LCFH is a risk factor for LC and is increased with MF history, among never-smokers, younger adults, and those with maternal relatives with LC. Randomized controlled trials are needed to confirm the mortality benefit of LDCT screening in those with LCFH.

Preoperative Transient Elastography in Patients with Esophageal Cancer.

Since excessive alcohol consumption is a shared risk factor for esophageal cancer and liver fibrosis, it is possible that patients with esophageal cancer may develop unknown liver fibrosis or cirrhosis. We applied preoperative transient elastography (TE) to patients without recorded cirrhosis undergoing esophagectomy to clarify the validity in predicting postesophagectomy hepatic failure. The cohort consisted of 107 patients who received TE before esophagectomy between June 2018 and December 2021. Patients were categorized into two groups based on the fibrosis score yielded by preoperative TE (mild group: 0~2, n = 92; severe group: 3~4, n = 15). There was no significant difference in demographic data nor surgical variables between the two groups. None of the cohort encountered hepatic failure, yet the severe fibrosis group had a significantly higher rate of pleural effusion (40.0% versus 15.2%, p = 0.03). The areas under the curve (AUCs) of TE in predicting postoperative complications and 180-day mortality were 0.60 (95% CI: 0.46-0.74) and 0.67 (95% CI: 0.51-0.83), respectively. In conclusion, stratification of patients with esophageal cancer who had liver fibrosis by preoperative TE demonstrates significant validity in predicting postoperative pleural effusions. Recruitment of noncirrhotic patients with higher TE scores is warranted to examine its power in other parameters.

Demoralization and Its Association with Quality of Life, Sleep Quality, Spiritual Interests, and Suicide Risk in Breast Cancer Inpatients: A Cross-Sectional Study.

With decreasing mortality, the quality of life, spiritual needs, and mental health of breast cancer patients have become increasingly important. Demoralization is a poor prognostic factor for cancer patients. The extent of demoralization in breast cancer patients and its association with these factors remains unclear. This cross-sectional study was conducted at a Taiwanese medical center. We enrolled 121 participants (34 with high demoralization and 87 with low demoralization, as per the Mandarin Version of Demoralization Scale). High demoralization was associated with reduced quality of life, sleep quality, and spiritual interests. Multivariate analyses revealed that the scores of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire ≥ 62.5 (OR = 0.21, p = 0.002) and Spiritual Interests Related to Illness Tool Chinese Version ≥ 3.66 (OR = 0.11, p < 0.001) were associated with low demoralization. Demoralized patients with depression had a poorer quality of life and sleep quality. Although not statistically significant, depressed and demoralized participants were at a higher risk of suicide. Cancer patients with both depression and demoralization had the worst prognosis. Breast cancer patients exhibited demoralization when they had unmet bio-psycho-social-spiritual needs. An early assessment of demoralization may improve holistic healthcare for breast cancer patients.

Restoring the perfusion of accidentally transected right gastroepiploic vessels during gastric conduit harvest for esophagectomy using microvascular anastomosis: a case report and literature review.

BACKGROUND: Esophagectomy remains the standard treatment for esophageal cancer or esophagogastric junction cancer. The stomach, or the gastric conduit, is currently the most commonly used substitute for reconstruction instead of the jejunum or the colon. Preservation of the right gastric and the right gastroepiploic vessels is a vital step to maintain an adequate perfusion of the gastric conduit. Compromise of these vessels, especially the right gastroepiploic artery, might result in ischemia or necrosis of the conduit. Replacement of the gastric conduit with jejunal or colonic interposition is reported when a devastating accident occurs; however, the latter procedure requires a more extensive dissection and multiple anastomosis. CASE PRESENTATION: A 61-year-old male with a lower third esophageal squamous cell carcinoma (cT3N1 M0) who received neoadjuvant chemoradiation with a partial response. He underwent esophagectomy with a gastric conduit reconstruction. However, the right gastroepiploic artery was accidentally transected during harvesting the gastric conduit, and the complication was identified during the pull-up phase. An end-to-end primary anastomosis was performed by the plastic surgeon under microscopy, and perfusion of the conduit was evaluated by the ICG scope, which revealed adequate vascularization of the whole conduit. We continued the reconstruction with the revascularized gastric conduit according to the perfusion test result. Although the patient developed minor postoperative leakage of the esophagogastrostomy, it was controlled with conservative drainage and antibiotic administration. Computed tomography also demonstrated fully enhanced gastric conduit. The patient resumed oral intake smoothly later without complications and was discharged at postoperative day 43. CONCLUSION: Although the incidence of vascular compromise during harvesting of the gastric conduit is rare, the risk of conduit ischemia is worrisome whenever it happens. Regarding to our presented case, with the prompt identification of the injury, expertized vascular reconstruction, and a practical intraoperative evaluation of the perfusion, a restored gastric conduit could be applied for reconstruction instead of converting to more complicated procedures.

Demoralization in oral cancer inpatients and its association with spiritual needs, quality of life, and suicidal ideation: a cross-sectional study.

BACKGROUND: Demoralization is a common problem in oral cancer patients owing to the chronic and severe nature of their affliction. However, the association between demoralization and the patient's spiritual needs, quality of life, and suicidal ideation remains unclear. This study aims to provide insights into possible links between demoralization among oral cancer patients and its effects on the patient's spiritual needs, quality of life, and suicidal ideation. METHODS: We examined 155 Taiwanese oral cancer inpatients in Taichung Veterans General Hospital, Taiwan, using the following three rating scales: (a) Demoralization Scale Mandarin Version (DS-MV), (b) Spiritual Interests Related to Illness Tool, and (c) The Taiwan Chinese versions of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. Suicidal ideation was established if at least one of the two suicide-related items on the DS-MV scale were checked. We divided the participants into high- and low-demoralization groups, per the cutoff score of 30. We then explored group associations with sociodemographic features, quality of life, and spiritual needs. Logistic regression and receiver operating characteristic (ROC) curves were used to determine demoralization and its association between these variables. RESULTS: Fifty-five (35.5%) patients were categorized as having high demoralization (DS-MV scale score > 30), with scores for DS-MV for all patients being 27.2 ± 16.8. The rates of suicidal ideation were 29.1% (16/55) in the high-demoralization group and 2% (2/100) in the low-demoralization group, with an odds ratio (95% confidence interval) of 20.10 (4.41-91.55). Logistic regression analysis revealed significant effects of spiritual needs and global health status on the DS-MV scores (p < 0.001). Multivariate analyses further confirmed that only overall quality of life scores < 62.5 and spiritual needs < 3.7 significantly predicted the occurrence of high demoralization. CONCLUSION: High demoralization is associated with low satisfaction with spiritual needs, poor quality of life, and high risk of suicidal ideation. DS-MV may potentially be an effective tool for achieving holistic health care among oral cancer patients.

Diagnostic Accuracy of Whole-Body Computed Tomography for Incidental Ovarian Tumors in Patients with Prior Breast Cancer.

Whole-body computed tomography (WBCT) serves as the first-line imaging modality for breast cancer follow-up. To investigate the imaging characteristics and diagnostic accuracy of WBCT for incidental ovarian tumors in patients with prior breast cancer, we retrospectively reviewed a consecutive cohort of 13,845 patients with breast cancer, of whom 149 had pathologically-proven ovarian lesions. We excluded patients with ovarian diagnosis before breast cancer, CT scan not including ovary, CT-pathology interval >30 days, and severe CT artifact. Among our 60 breast cancer patients (median age, 46 years) with pathologically proven ovarian lesions, 49 patients had benign diseases, seven had primary ovarian cancer and four had ovarian metastasis from breast cancer. The histologic types of breast cancer with ovarian metastases included invasive ductal carcinoma, lobular carcinoma and angiosarcoma. Cystic ovarian lesions identified on WBCT during the breast cancer follow-up are more likely to be benign, while solid-cystic lesions are likely to be primary ovarian cancers, and solid lesions may indicate ovarian metastasis. The diagnostic accuracy, sensitivity, specificity, and areas under the receiver operating characteristic curve of WBCT were 98.3%, 100.0%, 98.0%, and 0.99 (malignant vs. benign); 90.0%, 100.0%, 85.7%, and 0.93 (metastasis vs. primary ovarian cancer), respectively. The only false positive solid lesion was a Sertoli-Leydig tumor. In conclusion, WBCT may help diagnose incidental ovarian tumors in patients with prior breast cancers and guide disease management.

Puestow's Procedure Performed During Gastric Conduit Harvesting.

Esophageal cancer survival has improved as a result of improvements in surgical techniques and preoperative chemoradiation. Excessive alcohol consumption is a shared risk factor for esophageal cancer and chronic alcoholic pancreatitis. Puestow's procedure is a treatment choice for pain relief and pancreatic duct decompression. It is logical to perform Puestow's procedure in patients undergoing esophagectomy with underlying chronic pancreatitis to preserve pancreatic function and restore quality of life in the setting of improved overall survival of patients with esophageal cancer. This report describes a preliminary experience with 2 patients who underwent both procedures during the same operation and achieved acceptable outcomes.

Transcatheter Arterial Chemoembolization with Drug-Eluting Beads for the Treatment of Hepatocellular Carcinoma: Recommended Selection for Small-Caliber (<100 µm) Beads.

Drug-eluting beads transarterial chemoembolization (DEB-TACE) is an alternative to conventional lipiodol-based TACE (cTACE) to treat hepatocellular carcinoma (HCC). With the advancement in pharmacology, small-caliber DEB-TACE (<100 µm) has been introduced since 2016. For the treatment of hepatic neoplasms or HCC, there is a tendency to use smaller beads by DEB-TACE to achieve more extensive tumor necrosis and a significant reduction in liver toxicity in comparison with that caused by cTACE. However, the indications and potential complications of small-caliber DEB-TACE remain uncertain and have not been well established, due to lack of randomized phase III clinical trials. Instead of systematic or meta-analysis review, this narrative review article describes the suggested indications and contraindications of DEB-TACE with small DEBs, benefit of super-selective embolization of the feeding arteries and the recommended selection of small-caliber DEB. This review was approved by the institutional review board (File Number: 1-105-05-158).

Predictors of Invasive Adenocarcinomas among Pure Ground-Glass Nodules Less Than 2 cm in Diameter.

Benign lesions, atypical adenomatous hyperplasia (AAH), and malignancies such as adenocarcinoma in situ (AIS), minimally invasive adenocarcinoma (MIA), and invasive adenocarcinoma (IA) may feature a pure ground-glass nodule (pGGN) on a thin-slide computed tomography (CT) image. According to the World Health Organization (WHO) classification for lung cancer, the prognosis of patients with IA is worse than those with AIS and MIA. It is relatively risky to perform a core needle biopsy of a pGGN less than 2 cm to obtain a reliable pathological diagnosis. The early and adequate management of patients with IA may provide a favorable prognosis. This study aimed to disclose suggestive signs of CT to accurately predict IA among the pGGNs. A total of 181 pGGNs of less than 2 cm, in 171 patients who had preoperative CT-guided localization for surgical excision of a lung nodule between December 2013 and August 2019, were enrolled. All had CT images of 0.625 mm slice thickness during CT-guided intervention to confirm that the nodules were purely ground glass. The clinical data, CT images, and pathological reports of those 171 patients were reviewed. The CT findings of pGGNs including the location, the maximal diameter in the long axis (size-L), the maximal short axis diameter perpendicular to the size-L (size-S), and the mean value of long and short axis diameters (size-M), internal content, shape, interface, margin, lobulation, spiculation, air cavity, vessel relationship, and pleural retraction were recorded and analyzed. The final pathological diagnoses of the 181 pGGNs comprised 29 benign nodules, 14 AAHs, 25 AISs, 55 MIAs, and 58 IAs. Statistical analysis showed that there were significant differences among the aforementioned five groups with respect to size-L, size-S, and size-M (p = 0.029, 0.043, 0.025, respectively). In the univariate analysis, there were significant differences between the invasive adenocarcinomas and the non-invasive adenocarcinomas with respect to the size-L, size-S, size-M, lobulation, and air cavity (p = 0.009, 0.016, 0.008, 0.031, 0.004, respectively) between the invasive adenocarcinomas and the non-invasive adenocarcinomas. The receiver operating characteristic (ROC) curve of size for discriminating invasive adenocarcinoma also revealed similar area under curve (AUC) values among size-L (0.620), size-S (0.614), and size-M (0.623). The cut-off value of 7 mm in size-M had a sensitivity of 50.0% and a specificity of 76.4% for detecting IAs. In the multivariate analysis, the presence of air cavity was a significant predictor of IA (p = 0.042). In conclusion, the possibility of IA is higher in a pGGN when it is associated with a larger size, lobulation, and air cavity. The air cavity is the significant predictor of IA.

The Use of Artificial Intelligence in the Differentiation of Malignant and Benign Lung Nodules on Computed Tomograms Proven by Surgical Pathology.

The purpose of this work was to evaluate the performance of an existing commercially available artificial intelligence (AI) software system in differentiating malignant and benign lung nodules. The AI tool consisted of a vessel-suppression function and a deep-learning-based computer-aided-detection (VS-CAD) analyzer. Fifty patients (32 females, mean age 52 years) with 75 lung nodules (47 malignant and 28 benign) underwent low-dose computed tomography (LDCT) followed by surgical excision and the pathological analysis of their 75 nodules within a 3 month time frame. All 50 cases were then processed by the AI software to generate corresponding VS images and CAD outcomes. All 75 pathologically proven lung nodules were well delineated by vessel-suppressed images. Three (6.4%) of the 47 lung cancer cases, and 11 (39.3%) of the 28 benign nodules were ignored and not detected by the AI without showing a CAD analysis summary. The AI system/radiologists produced a sensitivity and specificity (shown in %) of 93.6/89.4 and 39.3/82.1 in distinguishing malignant from benign nodules, respectively. AI sensitivity was higher than that of radiologists, though not statistically significant (p = 0.712). Specificity obtained by the radiologists was significantly higher than that of the VS-CAD AI (p = 0.003). There was no significant difference between the malignant and benign lesions with respect to age, gender, pure ground-glass pattern, the diameter and location of the nodules, or nodules <6 vs. ≥6 mm. However, more part-solid nodules were proven to be malignant than benign (90.9% vs. 9.1%), and more solid nodules were proven to be benign than malignant (86.7% vs. 13.3%) with statistical significance (p = 0.001 and <0.001, respectively). A larger cohort and prospective study are required to validate the AI performance.

A comparison of spring-loaded and vacuum-assisted techniques for stereotactic breast biopsy of impalpable microcalcification lesions: experience at Chang Gung Memorial Hospital at Linkou.

BACKGROUND: The aim of this study was to assess the diagnostic performance of stereotactic core needle breast biopsy using spring-loaded or vacuum-assisted techniques for impalpable microcalcification lesions in Taiwanese women. METHODS: We retrospectively reviewed the data of patients who received stereotactic core needle breast biopsy for impalpable mammographic microcalcification lesions from January 1999 to February 2009. The accuracy, false negative rate, ductal carcinoma in situ (DCIS) upgrade rate and rate of concordance with biopsy procedures were determined. We also compared the diagnostic performance between the vacuum-assisted and spring-loaded techniques. RESULTS: A total of 335 breast stereotactic core needle biopsy procedures (218 by spring-loaded and 117 by vacuum-assisted technique) were enrolled for analysis. The overall accuracy, false negative rate, DCIS upgrade rate and concordance rate with stereotactic core needle biopsy were 88.5%, 17.3%, 23.1% and 83.8% respectively. The vacuum-assisted technique yielded better results than the spring-loaded technique in accuracy (100% vs. 84%), and the false negative (7.1% vs. 21%), DCIS upgrade (0% vs. 37.5%), and concordance rates (95% vs. 79.6%). CONCLUSION: Stereotactic core needle biopsy is a feasible technique in diagnosing impalpable microcalcification lesions of the breast in Taiwanese women. The diagnostic performance of the vacuum-assisted technique was better than that of the spring-loaded technique.

Ultrasound-guided core needle biopsy of cervical lymphadenopathy in patients with lymphoma: the clinical efficacy and factors associated with unsuccessful diagnosis.

This study attempts to identify factors that influence the success or failure of subclassifying 154 cases of neck lymphoma by ultrasound-guided core needle biopsy (UGCNB). Variables including age, gender, nodal size, cutting needle bore, number of core tissues obtained, presence of nodal necrosis or infarct, fragmentation of the specimens and subclassification of lymphoma were reviewed and statistically analyzed to check if they were related to the success of UGCNB. UGCNB was successful in subclassifying lymphoma in 138 (89.7%) cases, in diagnosing lymphoma in 11 (7.1%) and unsuccessful in diagnosing lymphoma in five (3.2%) cases. No complications were encountered. The factors leading to failure in subclassification included the presence of composite lymphoma (p = 0.001), nodal necrosis or infarct (p = 0.001) and insufficiency or fragmentation of the specimens (p < 0.001). UGCNB is a safe and efficient procedure in subclassifying lymphoma. It may obviate surgical biopsy in 89.7% of cases.
