In situ ascending aortic thrombus in a patient with metastatic lung adenocarcinoma and no aortic atherosclerosis or cisplatin exposure: a case report.

BACKGROUND: An ascending aortic thrombus is exceedingly rare. Two instances have been reported in the setting of lung cancer, but only after cisplatin use, which is associated with hypercoagulability. We present the first case of a patient with lung cancer who developed an ascending aortic thrombus without structural risk factors or chemotherapy use. CASE: A 60-year-old white female with significant smoking history presented with several weeks of malaise. A chest computed tomography scan revealed a 2.2-cm right upper lobe mass. As an outpatient, right hilar lymph node immunohistochemistry (IHC) samples via endobronchial ultrasound confirmed thyroid transcription factor-1 adenocarcinoma. After the procedure, the patient endorsed dyspnea and was advised to go to the emergency department. A chest computed tomography angiography identified a new 2.4 × 1.1 × 1.1 cm thrombus within the proximal aortic arch. No pulmonary emboli or intrapulmonary shunts were identified. A hypercoagulable workup was negative. Transthoracic echocardiogram was without left ventricular thrombus, akinesis or hypokinesis, left atrial dilation, or intracardiac shunts. A lower extremity ultrasound was negative for deep vein thrombosis. Given the procedural risk, thrombectomy was deferred. The patient was transitioned to enoxaparin, and a repeat computed tomography for resolution is in process. CONCLUSION: To our knowledge, this is the only case detailing an in situ ascending aortic thrombus in the setting of lung cancer, without structural risk factors, chemotherapy use, or other hypercoagulable comorbidities. Optimal management for an aortic thrombus and malignant disease is less clear. Clinicians should be vigilant for unusual arterial thromboses in patients with high metastatic burden.

A Case of Gallbladder Cancer with Trousseau Syndrome Successfully Treated Using Radical Resection.

Trousseau syndrome is characterized by cancer-associated systemic thrombosis. We describe the first case of a successfully treated gallbladder adenocarcinoma accompanied by Trousseau syndrome. A 66-year-old woman presented with right hemiplegia. Magnetic resonance imaging identified multiple cerebral infarctions. Her serum carbohydrate antigen 19-9 and D-dimer levels were markedly elevated, and a gallbladder tumor was detected via abdominal computed tomography. Venous ultrasonography of the lower limbs revealed a deep venous thrombus in the right peroneal vein. These findings suggested that the brain infarctions were likely caused by Trousseau syndrome associated with her gallbladder cancer. Radical resection of the gallbladder tumor was performed. The resected gallbladder was filled with mucus and was pathologically diagnosed as an adenocarcinoma. Her postoperative course was uneventful, and she received a one-year course of adjuvant therapy with oral S-1. No cancer recurrence or thrombosis was noted 26 months postoperatively. Despite concurrent Trousseau syndrome, a radical cure of the primary tumor and thrombosis could be achieved with the appropriate treatment.

Testicular metastasis of prostate adenocarcinoma: the other side of orchiepididymitis.

Background: Metastatic prostate adenocarcinoma is a rare event and there are few references to this topic. We report an unusual case of prostate cancer metastasis and review of contemporary literature. Moreover, we discuss the pathogenesis and the clinical aspects of this event. Case presentation: A 70-year-old patient was admitted to the hospital for right scrotal pain. The ultrasound examination described an increase in testicular size, suggesting the possibility of orchiepididymitis. Past medical history reported a previous prostate adenocarcinoma. Inflammatory blood tests were normal. Importantly, PSA was 3.3 ng/ml. PET scan positivity in the scrotum raised suspicion of a relapse. Therefore, he underwent right orchiectomy. Conclusion: Although metastatic prostate adenocarcinoma is rare, a correct diagnosis is of paramount importance because the therapy changes accordingly. Patients who complain of scrotal pain need to be examined accurately. Although the most common cause behind this symptom is infectious, the patient's past medical history should be reviewed to exclude previous malignancies.

Body composition measurements and clinical outcomes in patients with resectable pancreatic adenocarcinoma - analysis from SWOG S1505.

BACKGROUND: Sarcopenic obesity and muscle attenuation have been associated with survival in patients with borderline resectable and advanced pancreatic ductal adenocarcinoma (PDA); however, these relationships are unknown for patients with resectable PDA. This study examined the associations between skeletal muscle and adipose tissue as measured on baseline computed tomography (CT) and the overall survival (OS) of participants with resectable PDA in a secondary analysis of the Southwest Oncology Group S1505 clinical trial (identifier: NCT02562716). METHODS: The S1505 phase II clinical trial enrolled patients with resectable PDA who were randomized to receive modified FOLFIRINOX or gemcitabine and nab-paclitaxel as perioperative chemotherapy, followed by surgical resection. Baseline axial CT images at the L3 level were analyzed with externally validated software, and measurements were recorded for skeletal muscle area and skeletal muscle density, visceral adipose tissue area (VATA) and density, and subcutaneous adipose tissue area and density. The relationships between CT metrics and OS were analyzed using Cox regression models, with adjustment for baseline participant characteristics. RESULTS: Of 98 eligible participants with available baseline abdominal CT, 8 were excluded because of imaging quality (eg, orthopedic hardware), resulting in 90 evaluable cases: 51 men (57.0%; mean age, 63.2 years [SD, 8.5]; mean body mass index [BMI], 29.3 kg/m2 [SD, 6.4]), 80 White (89.0%), 6 Black (7.0%), and 4 unknown race (4.0%). Sarcopenia was present in 32 participants (35.9%), and sarcopenic obesity was present in 10 participants (11.2%). Univariable analyses for the 6 variables of interest indicated that the standardized mean difference (hazard ratio [HR], 0.75; 95% CI, 0.57-0.98; P = .04) was statistically significantly associated with OS. In models adjusted for sex, race, age, BMI, performance score, contrast use, sarcopenia, and sarcopenic obesity, VATA was statistically significantly associated with OS (HR, 1.58; 95% CI, 1.00-2.51; P = .05). No difference was observed in OS between participants according to sarcopenic obesity or sarcopenia categories. The median OS estimates were 25.1 months for participants without sarcopenic obesity, 18.6 months for participants with sarcopenic obesity, 23.6 months for participants without sarcopenia, and 27.9 months for participants with sarcopenia. CONCLUSION: This was the first study to systematically evaluate body composition parameters in a prospective multicenter trial of patients with resectable PDA who received perioperative chemotherapy. Visceral adipose tissue was associated with survival; however, there was no association between OS and sarcopenia or sarcopenic obesity. Further studies should evaluate these findings in more detail.

A successful endovascular aortic repair of aortoesophageal fistula following esophagectomy: a case report and literature review.

BACKGROUND: Aortoesophageal fistula (AEF) is an extremely rare and highly fatal complication leading to a high risk of morbidity and mortality. Successful management of AEF after esophagectomy for esophageal carcinoma has rarely been reported in the literature. CASE PRESENTATION: Here we present a rare case of a 44-year-old female with complications of AEF after esophagectomy for esophageal carcinoma, mainly presented as vomiting of blood. Both computed tomographic and computed tomography angiography of the chest showed bilateral pleural effusion and atelectasis, while gastroscopy showed large gastrointestinal bleeding. Emergency surgery was performed that included the removal of the mediastinal abscess, left lower pulmonary wedge resection, and thoracic endovascular aortic repair (TEVAR), followed by supportive treatment. The surgery went successful, and the patient was followed up for 1 year after discharge and showed good recovery. We also reviewed previous literature on the history, causes, pathophysiology, clinical presentation, diagnosis, and treatment of AEF after esophagectomy for esophageal adenocarcinoma. CONCLUSIONS: In our case, thoracotomy combined with TEVAR was effective in treating AEF after esophagectomy for esophageal adenocarcinoma. This case provides successful experiences for clinical diagnosis and treatment of AEF after esophagectomy for esophageal carcinoma.

The "double-fired" gastro-jejunostomy as a form of improved efficiency during Whipple procedure.

BACKGROUND: Gastro-jejunostomy (GJ) after pylorus-resecting pancreatoduodenectomy (PD) is most commonly performed in a hand-sewn fashion. Intestinal stapled anastomosis are reported to be as effective as hand-sewn in terms of patency and risk of leakage in other indications. However, the use of a stapled gastro-jejunostomy hasn't been fully assessed in PD. The aim of the present technical report is to evaluate functional outcomes of stapled GJ during PD, its associated effect on operative time and related complications. METHODS: The institutional database for pancreatic duct adenocarcinoma (PDAC) was retrospectically reviewed. Pylorus resecting open PD without vascular or multivisceral resections were considered for the analysis. The incidence of clinically significant delayed gastric emptying (DGE from the International Stufy Group of Pancreatic Surgery (ISGPS) grade B and C), other complications, operative time and overall hospitalization were evaluated. RESULTS: Over a 10-years study period, 1182 PD for adenocarcinoma were performed and recorded in the database. 243 open Whipple procedures with no vascular and with no associated multivisceral resections were available and constituted the study population. Hand-sewn (HS) anastomosis was performed in 175 (72 %), stapled anastomosis (St) in 68 (28 %). No significant differences in baseline characteristics were observed between the two groups, with the exception of a higher rate of neoadjuvant chemotherapy in the HS group (74 % St vs. 86 % HS, p = 0.025). Intraoperatively, a significantly reduced median operative time in the St group was observed (248 min St vs. 370 mins HS, p < 0.001). Post-operatively, rates of clinically relevant delayed gastric emptying (7 % St vs. 14 % HS, p = 0.140), clinically relevant pancreatic fistula (10 % St, 15 % HS, p = 0.300), median length of stay (7 days for each group, p = 0.289), post-pancreatectomy hemorrhage (4.4 % St vs. 6.3 % HS, p = 0.415) and complication rate (22 % St vs. 34 % HS, p = 0.064) were similar between groups. However, readmission rates were significantly lower after St GJ (13.2 % St vs 29.7 % HS, p = 0.008). CONCLUSION: Our results indicate that a stapled GJ anastomosis during a standard Whipple procedure is non-inferior to a hand-sewn GJ, with a comparable rate of DGE and no increase of gastrointestinal related long term complications. Further, a stapled GJ anastomosis might be associated with reduced operative times.

Short-Term Prognostic Effect of Comprehensive Complication Index in Patients With Gastric Cardia Adenocarcinoma.

INTRODUCTION: The Clavien-Dindo Classification (CDC) has been traditionally used for assessing postoperative complications. Recently, the Comprehensive Complication Index (CCI) has been introduced as a new tool. However, its prognostic significance in Gastric Cardia Adenocarcinoma (GCA) is yet to be determined. METHODS: The CCI and CDC of 203 patients who underwent radical surgery for GCA at Jinling Hospital from 2016 to 2023 were evaluated. Primary outcome variables included Hospital Length of Stay, duration of intensive care unit stay postoperatively, time to return to normal activities, and total hospitalization cost. The area under the curve was used to measure the correlation strength of the CCI and CDC for these outcomes. RESULTS: The CCI demonstrated superior association strength, indicated by higher area under the curve values for all primary outcome variables compared to the CDC: Hospital Length of Stay (0.956 versus 0.910), intensive care unit stay duration (0.969 versus 0.954), time to return to normal activities (0.983 versus 0.962), and total hospitalization cost (0.925 versus 0.911). CONCLUSIONS: The CCI showed a stronger positive association than the CDC with short-term postoperative complications in GCA. It has potential implications for improving postoperative patient management.

Clinical features and prognostic factors of patients with cancer-associated stroke.

BACKGROUND: Cerebrovascular diseases in cancer patients significantly aggravate their condition and prognosis; therefore, prompt and accurate diagnosis and treatment are important. The purpose of this study was to investigate patient demographics, laboratory data, brain magnetic resonance imaging (MRI) findings, and prognosis among patients with stroke and cancer, especially cancer-associated ischemic stroke (CAIS). METHODS: We performed a retrospective, single-center study. We enrolled consecutive patients who had acute stroke and were admitted to our hospital between January 2011 and December 2021. We collected general demographic characteristics, cancer histopathological type, laboratory data, brain MRI findings, and prognosis data. RESULTS: Among 2040 patients with acute stroke, a total of 160 patients (7.8%) had active cancer. The types of strokes were cerebral infarction, cerebral hemorrhage, subarachnoid hemorrhage, and transient ischemic attack in 124, 25, 5, and 6 patients, respectively. Among the patients with ischemic stroke, there were 69 cases of CAIS. Pancreas and adenocarcinoma were the most frequent types of primary tumor and histopathology. Patients with adenocarcinoma and those with cerebral infarctions in both bilateral anterior and posterior cerebral circulation areas showed higher D-dimer levels. Pancreatic cancer and high plasma D-dimer levels were associated with poor survival rate. CONCLUSION: CAIS was seen more frequently in patients with pancreatic cancer and adenocarcinoma. Pancreatic cancer and high plasma D-dimer levels were potential factors of poor prognosis in patients with CAIS.

Spontaneous tumour lysis secondary to gastric adenocarcinoma.

We present a case of a man in his 70s who presented with worsening rectal and back pain associated with weight loss, dyspnoea and brownish discolouration of urine. Physical examination noted abdominal distention and epigastric tenderness. Laboratory investigations revealed acute kidney injury, hyperkalaemia, hyperphosphataemia and hyperuricaemia. Contrast CT of the abdomen/pelvis showed multiple, low-density masses throughout the liver, suspicious for metastatic disease. Oesophagogastroduodenoscopy demonstrated a large, fungating, infiltrative and ulcerated mass in the gastric body and lesser curvature of the stomach. Surgical pathology confirmed invasive moderately differentiated gastric adenocarcinoma. He met both the laboratory and clinical criteria for spontaneous tumour lysis syndrome (STLS) as per the Cairo-Bishop criteria. He was managed with aggressive fluid hydration, rasburicase and allopurinol, resulting in improvement in his renal function and laboratory findings. STLS of solid organ tumours, especially gastric adenocarcinoma, is rare and requires early detection with timely management to ensure favourable outcomes.

Comparison of the 68 Ga-FAPI Versus 18 F-FDG in Gastric Adenocarcinoma and Anthracosis-Associated Lymph Nodes: FAPI Unmasking False-Negatives and False-Positives.

ABSTRACT: A 73-year-old woman with poorly differentiated gastric adenocarcinoma was referred to 18 F-FDG PET/CT for evaluation of the disease. FDG PET/CT showed intense uptake in the disseminated lymph nodes. However, there was no uptake in the primary tumoral lesion. Subsequently, 68 Ga-FAPI-04 PET/CT was performed with the decision of the tumor board and demonstrated intense uptake in the tumoral lesion. However, there was low or no uptake in disseminated lymph nodes. Tru-cut biopsy results revealed that all the lymph nodes were associated with anthracosis.

Unusual complication of pancreatic adenocarcinoma: massive liver necrosis.

Pancreatic adenocarcinoma is a malignant and aggressive disease, whose diagnose is achieved in many cases at advanced stage. We present the case of a 63-year-old woman diagnosed with adenocarcinoma of the pancreatic head and body, which invaded hepatic artery and presented with portal vein thrombosis. She consulted for melena and upper endoscopy showed varicose lesions in the second part of duodenum. The patient developed acute worsening of anemia with hemodynamic inestability. Urgent contrast enhanced computed tomography revealed a massive hepatic necrosis without identification of the hepatic artery. Massive hepatic necrosis is an infrequent clinical condition described in bibliography after invasive procedures. The complete obstruction of the liver vascular system due to pancreatic cancer is an extremely unusual cause of massive liver necrosis.

Meningeal carcinomatosis with decreased visual acuity: a case report.

Meningeal carcinomatosis is a condition in which cancer cells diffusely metastasize to the cerebral pia mater in the cerebrospinal membrane or cerebrospinal cavity. It causes a wide array of symptoms according to the site of metastasis. The prognosis is poor, especially in metastasis from solid tumors. This study reports a case of meningeal carcinomatosis caused by advanced gastric cancer, manifested by headache and vision loss. The patient was a 69-year-old man who underwent head computed tomography (CT) and magnetic resonance imaging (MRI) for persistent headaches. No abnormal findings were found; however, his vision declined, convulsions occurred, and cerebrospinal fluid (CSF) cytology showed poorly differentiated adenocarcinoma. Therefore, meningeal carcinomatosis was diagnosed. The patient died after receiving FOLFOX therapy to relieve symptoms and prolong his life. An autopsy showed no invasion of the optic nerve or surrounding tissues. As the frequency of complications of meningeal carcinomatosis in solid cancers is rare, it is crucial to actively suspect and make an early diagnosis.

Survival by sex and HIV status in patients with anal cancer in the USA between 2001 and 2019: a retrospective cohort study.

BACKGROUND: The risk of anal cancer is increased among people with HIV, particularly men who have sex with men. Estimating survival by HIV status and sex and identifying groups at high risk is crucial for documenting prognostic differences between populations. We aimed to compare all-cause and anal cancer-specific survival in patients with anal cancer with and without HIV, stratified by sex, and to identify predictors of survival, stratified by HIV status. METHODS: In this retrospective cohort study, we used data from the HIV/AIDS Cancer Match Study of 13 population-based HIV and cancer registries throughout the USA. We included individuals aged 20-79 years diagnosed with invasive anal cancer between 2001 and 2019. To estimate associations between HIV status and both all-cause and anal cancer-specific mortality overall, we used Cox proportional hazards models, adjusting for year of and age at diagnosis, sex, race and ethnicity, histology, cancer stage, region, and treatment. We also calculated sex-specific adjusted hazard ratios (HRs). By HIV status, we identified characteristics associated with mortality. Models among people with HIV were further adjusted for AIDS status and HIV transmission risk group. FINDINGS: Between Jan 1, 2001, and Dec 31, 2019, 1161 (43·6%) of 2662 patients with anal cancer and HIV and 7722 (35·4%) of 21 824 patients without HIV died. HIV was associated with a 1·35 times (95% CI 1·24-1·47) increase in all-cause mortality among male patients and a 2·47 times (2·10-2·90) increase among female patients. Among patients with HIV, all-cause mortality was increased among non-Hispanic Black individuals (adjusted HR 1·19, 95% CI 1·04-1·38), people with AIDS (1·36, 1·10-1·68), people who inject drugs (PWID; 1·49, 1·17-1·90), patients with adenocarcinoma (2·74, 1·82-4·13), and those with no or unknown surgery treatment (1·34, 1·18-1·53). HIV was associated with anal cancer-specific mortality among female patients only (1·52, 1·18-1·97). Among patients with HIV, anal cancer-specific mortality was increased among patients with adenocarcinoma (3·29, 1·89-5·72), those with no or unknown treatment (1·59, 1·17-2·17), and PWID (1·60, 1·05-2·44). INTERPRETATION: HIV was associated with all-cause mortality among patients with anal cancer, especially women. Anal cancer-specific mortality was elevated among female patients with HIV. As screening for anal cancer becomes more widespread, examining the effects of screening on survival by HIV status and sex is crucial.

Clinical analysis of twenty-one cases of acute ischemic stroke related to Trousseau syndrome.

BACKGROUND: Trousseau syndrome (TS) is relatively rare and easily overlooked by clinicians, causing misdiagnosis and affecting subsequent treatment. OBJECTIVE: In this study, clinical features, laboratory examination, imaging features, treatment, and prognosis of patients with TS were discussed. METHODS AND MATERIAL: From February 2018 to April 2022, cases of 21 patients with malignant tumors complicated by acute ischemic stroke (AIS) were admitted to the Neurology Department of the hospital, and were retrospectively analyzed and discussed based on the literature. RESULTS: Twenty-one cases were included in the study. Of these, 95.23% (20/21) developed AIS 6-21 months after the onset of malignant tumors, 9.52% (2/21) had ischemic stroke as the first symptom, 4.76% (1/21) had recurrent ischemic stroke, and 14.29% (3/21) subsequently experienced venous and arterial thrombosis events; 80.95% (17/21) were pathologically confirmed to have adenocarcinoma; and 90.47% (19/21) of infarction cases involved multiple blood vessel feeding sites. MRI showed multiregional, multifocal patchy infarcts. D-dimer concentration was higher than normal in all patients. In addition, 61.90% (13/21) of the patients had poor outcomes according to mRS. CONCLUSION: TS is a rare clinical type. It is often associated with adenocarcinoma, and the treatment is different from that of conventional cerebral infarction and the prognosis is very poor. In clinical practice, for AIS of unknown cause, if MRI shows multiple small lesions accompanied by a significant increase in D-dimer, routine screening for latent malignant tumors is recommended.

Risk of Esophageal Cancer in Achalasia: A Matched Cohort Study Using the Nationwide Veterans Affairs Achalasia Cohort.

INTRODUCTION: Achalasia is a postulated risk factor of esophageal cancer (EC); however, EC-associated risk in achalasia is understudied. We aimed to evaluate EC risk among individuals within the nationwide Veterans Affairs Achalasia Cohort. METHODS: We conducted a matched cohort study among US veterans aged 18 years or older from 1999 to 2019. Individuals with achalasia were age matched and sex matched 1:4 to individuals without achalasia. Follow-up continued from study entry until diagnosis with incident/fatal EC (primary outcome), death from non-EC-related causes, or end of the study follow-up (December 31, 2019). Association between achalasia and EC risk was examined using Cox regression models. RESULTS: We included 9,315 individuals in the analytic cohort (median age 55 years; 92% male): 1,863 with achalasia matched to 7,452 without achalasia. During a median 5.5 years of follow-up, 17 EC occurred (3 esophageal adenocarcinoma, 12 squamous cell carcinoma, and 2 unknown type) among individuals with achalasia, compared with 15 EC (11 esophageal adenocarcinoma, 1 squamous cell carcinoma, and 3 unknown type) among those without achalasia. EC incidence for those with achalasia was 1.4 per 1,000 person-years, and the median time from achalasia diagnosis to EC development was 3.0 years (Q1-Q3: 1.3-9.1). Individuals with achalasia had higher cumulative EC incidence at 5, 10, and 15 years of follow-up compared with individuals without achalasia, and EC risk was 5-fold higher (hazard ratio 4.6, 95% confidence interval: 2.3-9.2). DISCUSSION: Based on substantial EC risk, individuals with achalasia may benefit from a high index of suspicion and endoscopic surveillance for EC.
