Transitional Changes of Anxiety, Pain and Other Symptoms in Cancer Patients Admitted to a Palliative Care Unit, Evaluated Using the Support Team Assessment Schedule - Japanese Version.

Objective: Association between physical symptoms and psychosocial difficulties of cancer patients has been reported widely. Nevertheless, the effects of pain and other symptom control on anxiety in such patients have not been investigated well. We investigated the association of improvement of pain and other symptoms with patient anxiety, and assessed factors associated with improvement of such symptoms. Methods: Data of patients with advanced cancer admitted to a palliative care unit during August 2018 - June 2022 were analyzed retrospectively. Severity of pain, other symptoms, and anxiety was assessed by the Support Team Assessment Schedule Japanese version (STAS-J) administered at admission and after 2 weeks. Patients' physical data, their Palliative Prognostic Index (PPI) at admission, and their overall survival were collected and recorded. Results: Data of 701 patients were analyzed. Improvement of pain or other symptoms after 2 weeks was not associated with the PPI total score or actual survival (P = .105 and .999). Patients with higher anxiety on admission experienced improvement of pain or other symptoms more frequently (P = .005). Worsening of anxiety was observed less in patients who experienced improvement in pain or other symptoms after 2 weeks (P = .027). Conclusion: Pain or other symptoms of patients with advanced cancer was improved irrespective of the general condition indicated with actual survival and prognosis-predictive factors. These findings suggest the importance of pain and other symptoms' improvement and its important roles in the management of patient psychosocial problems such as anxiety.

Arteriolar hyalinization at 0-hour biopsy predicts long-term graft function in deceased kidney transplantation.

OBJECTIVES: Regarding the relationship between donor kidney quality and renal graft function after deceased kidney transplantation (KTx) following donation after cardiac death (DCD), the evaluation timing varies depending on the study. Evaluation of histology and changes in long-term renal graft function is limited. METHODS: A retrospective single-center study included 71 recipients who underwent 0-hour biopsy for KTx from DCD. The recipients were divided into two groups to evaluate factors related to renal graft function (study1). The two groups were categorized as stable graft function and poor graft function with the change of estimated glomerular filtration rate (eGFR) after KTx. The recipients were then divided into four groups to assess whether the factors identified in study1 were related to the change in long-term renal graft function (study2). They were categorized as follows: Improved, Stable, Deteriorated, and Primary non-function with the change of eGFR after KTx. RESULTS: In study1, donor age ≥ 50 years (29.5% vs. 65.2%; p = 0.09), banff arteriolar hyalinosis (ah) score (0.66 ± 0.78 vs. 1.2 ± 1.0; p = 0.018), and presence of glomerulosclerosis (43.2% vs. 76.2%; p = 0.017) were significant risk factors for poor long-term graft function. When the recipients were divided into four groups, the severity of ah correlated well with changes in long-term renal function. CONCLUSIONS: We can predict the shift in long-term renal graft function after KTx from DCD according to the severity of ah by 0-hour biopsy.

Propensity score-matched comparison of total arterial off- and on-pump coronary artery bypass with complete revascularization.

Little is known regarding the long-term (> 10 years) outcomes and risk factors of total arterial coronary artery bypass grafting (CABG). This study evaluated the long-term outcomes and risk factors for all-cause mortality and major adverse cardiac and cerebrovascular events (MACCEs) following total arterial on-pump CABG (ONCAB) or off-pump CABG (OPCAB) with complete revascularization. This retrospective cohort analysis enrolled patients with stable angina who underwent total arterial CABG with complete revascularization in our institute between July 2000 and June 2019. The endpoints were all-cause mortality and MACCE incidence, including a comparison between OPCAB and ONCAB. Long-term (10-year) outcomes were analyzed using propensity score-matched pairs, and risk factors were evaluated using univariate and multivariate analyses. Overall, 401 patients who underwent primary total arterial CABG were classified into the OPCAB (n = 269) and ONCAB (n = 132) groups. Using propensity score matching (PSM), 88 patients who underwent OPCAB were matched with 88 patients who underwent ONCAB. The mean follow-up period was 7.9 ± 6.3 years. No significant difference in all-cause mortality (hazard ratio, 1.04; 95% confidence interval, 0.53-2.04; p = 0.9138) and MACCE incidence (hazard ratio, 1.06; 95% confidence interval, 0.68-1.65; p = 0.7901) was observed between the two groups. Renal failure requiring dialysis was a significant risk factor for mortality (p < 0.0001) and MACCEs (p = 0.0003). Long-term outcomes of total arterial OPCAB and ONCAB with complete revascularization showed similar findings using PSM. Renal failure requiring dialysis was a significant risk factor for mortality and morbidity.Journal standard instruction requires an unstructured abstract; hence the headings provided in abstract were deleted.

Expression patterns of aquaporins 1, 3, 5 in canine mammary gland carcinomas.

Aquaporins (AQPs) are water channel proteins, and the expression of AQPs in carcinoma cells has received much attention over the last 15 years. In the veterinary field, however, little is known about the expression of AQPs. In the present study using immunohistochemistry, we examined the expression of AQP1, AQP3, and AQP5 in canine mammary gland carcinomas. The 27 samples comprised 10 grade I, 12 grade II, and 5 grade III samples (See Materials and Methods section for grade classification method). AQP1 was expressed in only 2 of the grade III carcinomas, and the expression was limited to spindle-shaped cells in the solid structure and on the outside of the solid mass. AQP3-positive cells were observed in 20 of 22 grade I and II samples. On the other hand, among grade III carcinomas, AQP3 was expressed only in spindle-shaped cells in 1 sample. AQP5 was expressed in all grade I and II carcinomas but not in the grade III tumors. In addition, enhanced expression of basolateral AQP3 and apical AQP5 was observed in lobular hyperplastic cells. These results suggest that the expression patterns of AQP3 and AQP5 can be of help for judging the grading of canine mammary tumors and that AQP1 is likely to be involved in metastasis. Moreover, AQP3 and AQP5 might be relevant to lactation in female dogs.

[Semi-acute Surgery for Ventricular Septal Perforation After Unsuccessful Intra-aortic Balloon Pumping Support:Report of a Case].

Ventricular septal perforation( VSP) after acute myocardial infarction( MI) is a serious condition that requires surgical treatment. However, good outcome is not always obtained. The mortality rate of VSP is particularly high in cases whom emergency surgery is performed early in the course of the disease, and the timing of surgery is known to affect prognosis. In this case report, the patient assisted with intra-aortic balloon pump. VSP closure surgery (a modified David-Komeda technique) underwent 8 days after MI onset. Except for mild residual shunt, the patient experienced no adverse event during postoperative course and was discharged 30 days after the surgery. This case illustrated timing of surgery as well as adequate mechanical cardiopulmonary assistance and surgical technique is important.

Pharmacological study on the enhancing effects of U46619 on guinea pig urinary bladder smooth muscle contraction induced by acetylcholine and α,ß-methylene ATP and the possible involvement of protein kinase C.

We examined whether U46619 (a prostanoid TP receptor agonist) could enhance the contractions of guinea pig urinary bladder smooth muscle (UBSM) in response to acetylcholine (ACh) and an ATP analog (α,ß-methylene ATP (αß-MeATP)) through stimulation of the UBSM TP receptor and whether protein kinase C (PKC) is involved. U46619 (10-7 M) markedly enhanced UBSM contractions induced by electrical field stimulation and ACh/αß-MeATP (3 × 10-6 M each), the potentiation of which was completely suppressed by SQ 29,548 (a TP receptor antagonist, 6 × 10-7 M). PKC inhibitors did not attenuate the ACh-induced contractions enhanced by U46619 although they partly suppressed the U46619-enhanced, αß-MeATP-induced contractions. While phorbol 12-myristate 13-acetate (PMA, a PKC activator, 10-6 M) did not enhance ACh-induced contractions, it enhanced αß-MeATP-induced contractions, an effect that was completely suppressed by PKC inhibitors. αß-MeATP-induced contractions, both with and without U46619 enhancement, were strongly inhibited by diltiazem. U46619/PMA enhanced 50 mM KCl-induced contractions, the potentiation of which was partly/completely attenuated by PKC inhibitors. These findings suggest that U46619 potentiates parasympathetic nerve-associated UBSM contractions by stimulating UBSM TP receptors. PKC-increased Ca2+ influx through voltage-dependent Ca2+ channels may partially play a role in purinergic receptor-mediated UBSM contractions enhanced by TP receptor stimulation.

[Branched Thoracic Endovascular Aortic Repair for Aortic Arch Aneurysm Following Severe Combined Valvular Disease:Report of a Case].

A 79-years-old frail man with severe combined valvular disease was referred to our hospital. Furthermore, chest computed tomography( CT) showed a saccular aneurysm in the aortic arch. We chose two staged repairs for risk reduction. As a first stage double valve replacement and tricuspid annuloplasty were performed. Three months later, we performed successful branched thoracic endovascular aortic repair( TEVAR) used physician modified Najuta which had hydrogel-reinforced fenestrations to provide a more secure connection with the bridging graft than fenestrations alone. Staged surgery with branched TEVAR used physician modified Najuta is a useful strategy in patients who have complex cardiac disease combined with aortic arch aneurysm.

Pretransplant BMI Should Be <25 in Japanese Kidney Transplant Recipients: A Single-Center Experience.

BACKGROUND: The aim of this study was to determine the appropriate body mass index (BMI) in Japanese kidney transplant (KTx) recipients. We analyzed the effects of pre- and post-transplant (Tx) obesity on graft and patient survival, perioperative complications, post-transplant diabetes mellitus (PTDM), and cardiovascular disease (CVD) in Japanese KTx recipients. METHODS: This retrospective study included 269 recipients who underwent KTx from 2008 through 2020 at Niigata University Hospital. Obesity was defined as a body mass index (BMI) ≥25 kg/m2. We examined the association between pre- and post-Tx obesity and graft survival, patient survival, the incidence of PTDM and CVD, and perioperative surgical complications. RESULTS: The graft survival rate was lower in the pre-Tx BMI ≥25 kg/m2 group, although there was no significant difference in patient survival. There was no difference in graft and patient survival between the post-Tx BMI ≥25 kg/m2 group and the <25 kg/m2 group. A pre-Tx BMI ≥25 kg/m2 was an independent risk factor for biopsy-proven allograft rejection. New-onset DM after transplantation was significantly more common in the BMI ≥25 kg/m2 group than in the BMI <25 kg/m2 group (36% vs 13%; P = .002). The incidence of CVD was significantly higher in the post-Tx BMI ≥30 kg/m2 group than in the BMI <30 kg/m2 group (50% vs 11%; P = .023). There were no differences in surgical operating time, intraoperative blood loss, or perioperative complications between the obese and non-obese groups. CONCLUSION: Pre-Tx BMI ≥25 kg/m2 may be a risk factor for allograft rejection and graft loss. Post-Tx BMI should be <25 kg/m2 to reduce the risk for PTDM.

[Giant Right Coronary Artery Pseudoaneurysm:Report of a Case].

Giant coronary artery aneurysm is very rare and there is no clear consensus regarding its treatment. Herein, we report a case of this unusual entity. The patient was a 75-year-old man in whom follow-up coronary angiography showed leakage of contrast agent from one of the #4 posterior descending( #4PD) branch of the right coronary artery. Enhanced computed tomography (eCT) revealed a giant pseudoaneurysm with a maximum diameter of 55 mm. Percutaneous balloon angioplasty had been performed in the same vessel for angina pectoris 20 years earlier. We excluded the pseudoaneurysm from arterial perfusion by closing both the wall defect and the culprit branch under cardiopulmonary bypass. There was no need for revascularization because there was another #4PD branch nearby. No adverse events were observed after surgery. Postoperative eCT scans confirmed that the aneurysm was completely thrombosed with no leakage.

A duodenal gastrointestinal stromal tumor mimicking a pancreatic neuroendocrine tumor: a case report.

BACKGROUND: Duodenal gastrointestinal stromal tumors are rare. If tumor growth is extraluminal and involves the head of the pancreas, the diagnosis of a duodenal gastrointestinal stromal tumor is difficult. CASE PRESENTATION: A 44-year-old Japanese woman was referred to our hospital with anemia. An enhanced computed tomography scan showed a hypervascular mass 30 mm in diameter, but the origin of the tumor, either the duodenum or the head of the pancreas, was unclear. Upper gastrointestinal endoscopy revealed bulging accompanied by erosion and redness in part of the duodenal bulb. Mucosal biopsy was not diagnostic. Endoscopic ultrasound fine-needle aspiration was difficult to perform because a pulsating blood vessel was present in the region to be punctured. These findings led to a diagnosis of pancreatic neuroendocrine tumor invasion to the duodenum. The patient underwent pancreaticoduodenectomy. Histologically, the tumor was made up of spindle-shaped cells immunohistochemically positive for c-Kit and CD34. The tumor was ultimately diagnosed as a duodenal gastrointestinal stromal tumor. CONCLUSION: Extraluminal duodenal gastrointestinal stromal tumors are rare and mimic pancreatic neuroendocrine tumors. Endoscopic ultrasound fine-needle aspiration is useful for preoperative diagnosis, but it is not possible in some cases. Intraoperative diagnosis based on a completely resected specimen of the tumor may be useful for modifying the surgical technique.

The mouse homolog of the mutant WASp responsible for human X-linked neutropenia renders granulopoiesis ineffective.

Severe congenital neutropenia (SCN) is characterized by severe neutropenia and recurrent critical infections. X-linked neutropenia (XLN) is caused by a gain-of-function mutation in the Wiskott-Aldrich syndrome gene (WAS), the product of which (WASp) is expressed only in blood cells, especially during neutrophil maturation. To investigate the mechanism of neutropenia, we established a novel knock-in mouse line expressing WASp-I292T. WASp-I292T neutrophils exhibited activated (dysregulated) actin polymerization. Although WASp-I292T mice did not recapitulate neutropenia, neutrophil levels were increased in the bone marrow, and extramedullary hematopoiesis was observed. Bone marrow neutrophils from WASp-I292T mice exhibited attenuated transmigration. These abnormalities were associated with downregulation of NFκB and TP53 and faulty activation of their downstream pathways.

[Aortic Regurgitation and Stanford Type A Aortic Dissection with Antiphospholipid Antibody Syndrome:Report of a Case].

Antiphospholipid antibody syndrome (APS) is associated with high morbidity and mortality resulting from hemorrhagic or thromboembolic events and compromised host immunity due to steroid use. We reported a successful surgery for aortic valve regurgitation (AR) and dissecting aortic aneurysm (DAA) in the ascending aorta in a patient with APS. A 75-year-old woman with AR and primary APS was transferred to our institute because of fever and dyspnea. She was given a diagnosis of pneumonia and congestive heart failure (CHF). Enhanced computed tomography (CT) incidentally revealed chronic DAA. After medical treatment for CHF and pneumonia, elective surgery to replace the aortic valve and ascending aorta was performed. We paid special caution to intraoperative hemostasis and perioperative anticoagulation management. No adverse event was observed in this patient's postoperative clinical course, and she was discharged home.

Intracholecystic Papillary Neoplasm Localized to the Cystic Duct: A Case Report.

Intracholecystic papillary neoplasm (ICPN) of the gallbladder is a premalignant lesion. An ICPN arising from the cystic duct is rare. A woman in her 60s exhibited dilatation of the common bile duct on computed tomography (CT) performed for screening of respiratory disease. The CT revealed an enhancing mass, 3.3 cm in diameter, in the cystic duct. Endoscopic ultrasonography showed a well-demarcated, hyperechoic mass in the dilated cystic duct. Endoscopic retrograde cholangiography showed that the common bile duct was slightly retracted by the dilated cystic duct. Cytological analysis of the bile juice did not show any evidence of malignancy. She was diagnosed with a cystic bile duct tumor suggestive of ICPN. Cholecystectomy, resection of the extrahepatic bile duct, and lymph node dissection were performed. Macroscopically, the papillary-proliferated tumor was localized to the cystic duct. No critical lesions were evident in the common bile duct. Histologically, the tumor in the cystic duct showed intraluminal growth with a papillary configuration without malignancy. Based on these findings, the tumor was diagnosed as an ICPN. We encountered a rare case of ICPN localized to the cystic duct of the gallbladder.

Distal Gastrectomy for Symptomatic Stage IV Gastric Cancer Contributes to Prognosis with Acceptable Safety Compared to Gastrojejunostomy.

BACKGROUND: The prognostic prolongation effect of reduction surgery for asymptomatic stage IV gastric cancer (GC) is unfavorable; however, its prognostic effect for symptomatic stage IV GC remains unclear. We aimed to compare the prognosis of gastrectomy and gastrojejunostomy for symptomatic stage IV GC. METHODS: This multicenter retrospective study analyzed record-based data of patients undergoing palliative surgery for symptomatic stage IV GC in the middle or lower-third regions between January 2015 and December 2019. Patients were divided into distal gastrectomy and gastrojejunostomy groups. We compared clinicopathological features and outcomes after propensity score matching (PSM). RESULTS: Among the 126 patients studied, 46 and 80 underwent distal gastrectomy and gastrojejunostomy, respectively. There was no difference in postoperative complications between the groups. Regarding prognostic factors, surgical procedures and postoperative chemotherapy were significantly different in multivariate analysis. Each group was further subdivided into groups with and without postoperative chemotherapy. After PSM, the data of 21 well-matched patients with postoperative chemotherapy and 8 without postoperative chemotherapy were evaluated. Overall survival was significantly longer in the distal gastrectomy group (p = 0.007 [group with postoperative chemotherapy], p = 0.02 [group without postoperative chemotherapy]). CONCLUSIONS: Distal gastrectomy for symptomatic stage IV GC contributes to prognosis with acceptable safety compared to gastrojejunostomy.

Endometrial Cancer After Pancreas-After-Kidney Transplantation: A Case Report and Review of the Literature.

BACKGROUND: As the number of long-term survivors after organ transplantation increases, malignancy has become a problem as a late complication. We herein report a case of endometrial cancer during the follow-up of pancreas transplantation after kidney transplantation. CASE PRESENTATION: A 49-year-old woman was diagnosed with endometrial cancer. The patient had developed type 1 diabetes at 8 years old and started insulin treatment, and at 29 years old, she started hemodialysis for diabetic nephropathy. At 31 years old, she received living donor kidney transplantation and withdrew from dialysis. Hypoglycemia unawareness began to occur frequently from around 36 years old, and at 48 years old, the patient underwent deceased donor pancreas transplantation after kidney transplantation and achieved insulin independence. At 49 years old, she was diagnosed with endometrial cancer. Surgical treatment (total abdominal hysterectomy with left salpingo-oophorectomy) was performed. The pathologic diagnosis was confirmed as stage 1A uterine endometrioid carcinoma grade 1. The postoperative course was uneventful. She was discharged from our hospital on postoperative day 8. There has been no evidence of recurrence and/or metastasis of endometrial cancer for 16 months since the surgery. CONCLUSIONS: Carcinogenesis after pancreas transplantation may be a lethal late complication. It is important to carry out regular screening examinations with carcinogenesis in mind.

Trans-cuff leakage in bio-Bentall operation.

We have reported a case of trans-cuff leakage that occurred in a composite graft of bio-Bentall operation. The leakage resolved several months after surgery, similar to the trans-cuff leakage seen in simple aortic valve replacement. We have proposed hypotheses on the mechanism of trans-cuff leakage during a bio-Bentall operation and suggested ways to prevent it from occurring.

Upregulation of NADPH Oxidase 2 Contributes to Renal Fibrosis in pcy Mice: An Experimental Model of Nephronophthisis.

BACKGROUND: DBA/2FG-pcy (pcy) mice harbor a homozygous Nphp3 missense mutation and develop nephronophthisis with renal interstitial fibrosis. Previous studies have shown that aberrant oxygen homeostasis contributes to the renal pathology in pcy mice, but the underlying molecular mechanism remains largely unknown. METHODS: pcy mice and a control strain, DBA/2N (DBA) mice, were used. Renal levels of 62 mRNAs involved in oxygen homeostasis were investigated by real-time PCR, and the resulting data were used for extraction of pathological pathways. On the basis of the genes found to be upregulated and pathway analysis, further studies were performed using immunoblotting, immunohistochemistry, and pharmacological intervention. RESULTS: In comparison with DBA mice, the levels of 18 mRNAs were altered by >2-fold in pcy mice. Pathway analysis extracted molecular pathways related to oxidative stress, inflammation, and cell adhesion. As the levels of mRNAs relevant to the NADPH oxidase 2 (NOX2) pathway were prominently (4 genes >5-fold) increased in pcy mice, we further analyzed the molecules related to this pathway. A time course study suggested that the pathway was gradually activated in pcy mice from at least 5 weeks of age. Immunohistochemistry study revealed that NOX2 protein was colocalized with a macrophage marker protein in the renal interstitium. Moreover, treatment of pcy mice with apocynin, an inhibitor of the NOX2 pathway, ameliorated the renal fibrosis. CONCLUSION: Our findings suggest that the activation of the NOX2 pathway, possibly mediated by macrophage infiltration, plays a pivotal role in progressive renal fibrosis in pcy mice.

Anal Atresia in a Patient Who Had Undergone Hartmann Procedure.

BACKGROUND Hartmann procedure can be necessary for the treatment of rectal cancer and colonic perforation. The distal diverted intestinal tract is usually disregarded, while the proximal colon is diverted with a stoma. Most of the reported complications related to a diverted intestinal tract following Hartmann procedure include inflammation and intestinal tumors; however, there are only a few reports about postoperative anal complications. Herein, we report a rare case of anal atresia following Hartmann procedure. Anal atresia is generally considered as a congenital malformation; therefore, this was an extremely rare case, as there are no previous reports about anal atresia following Hartmann procedure. CASE REPORT An 84-year-old woman presented to our hospital with a persistent feeling of incomplete evacuation. She had undergone Hartmann procedure for diverticular disease of the sigmoid colon, with perforation, 5 years ago and had no major complications after the surgery. She had no history of anal disorders such as hemorrhoids or anal fissures. On examination, her anus was found to be closed by a thin skin, and computed tomography revealed stool retention in the diverted rectum. The anus was surgically opened to remove the stool, after which the feeling of incomplete evacuation resolved with no subsequent recurrence. CONCLUSIONS This is the first report of anal atresia in a patient following Hartmann procedure. The surgical intervention was effective in resolving the blockage and relieving the patient's feeling of incomplete evacuation.

A liver metastasis 7 years after resection of a low-risk duodenal gastrointestinal stromal tumor.

Duodenal gastrointestinal stromal tumors (dGISTs) are rare, and a lack of consensus exists regarding their treatment, particularly for recurrent disease. We herein report a rare case of liver metastasis 7 years after resection of a low-risk duodenal gastrointestinal stromal tumor. A 45-year-old woman revealed positive fecal occult blood. Upper gastrointestinal endoscopy revealed a submucosal duodenal tumor with ulceration and oozing on the apex. Endoscopic ultrasound showed a hypoechoic mass originating in the submucosa. Contrast-enhanced abdominal computed tomography (CT) revealed a 30-mm hyper-vascular tumor in the duodenal bulb. The patient underwent partial resection of the duodenal bulb with distal gastrectomy, followed by Roux-en-Y reconstruction. Histopathological evaluation revealed a tumor comprised of spindle-shaped cells including 5 mitotic figures per 50 high-power fields. Immunohistochemical evaluation indicated that the tumor cells were positive for c-Kit and CD34 expression. The tumor was diagnosed as low-risk dGIST. Postoperative follow-up was continued, and 7 years later, CT revealed a 39-mm enhanced tumor in liver segment 4. The tumor was diagnosed as a metastatic liver tumor, and the patient underwent S4 partial hepatectomy. As a result of histological and immunohistochemical analysis, the tumor was diagnosed as a liver metastasis from dGIST. The patient has been receiving oral imatinib 400 mg daily and remains free of disease 5 years after her last surgery. Low-risk dGIST can metastasize relatively long after surgery. However, an excellent long-term prognosis may be achieved by combining complete resection and imatinib therapy in patients with recurrent liver metastases.

Alpha-fetoprotein-producing Colon Carcinoma with Rapidly Increasing Liver Metastases That Resulted in Death: A Case Report.

Alpha-fetoprotein (AFP) has been widely used as a tumor marker for detecting hepatocellular carcinoma and yolk sac tumors. Recently, cases of gastrointestinal cancer with elevated serum AFP levels have been reported. However, AFP-producing colon cancer is considered rarer than other AFP-producing gastrointestinal cancers. In this study, we report on a case of a 47-year-old woman who was diagnosed with sigmoid colon cancer and underwent sigmoidectomy and lymph node dissection. Postoperative adjuvant chemotherapy (AC) was performed after the curative surgery. After the seventh course of AC, multiple liver masses and enlarged systemic lymph nodes were detected; these were later diagnosed as liver metastases from sigmoid colon cancer. Laboratory examination revealed high AFP levels (14,657.8 ng/mL). After confirming the recurrence, her condition worsened rapidly, and she eventually died 8 months after the operation. Autopsy and histopathological findings showed that the liver mass was positive for AFP staining, but the sigmoid colon cancer tissue was not. We then determined that liver metastases of the colon cancer were more likely than germ cell carcinoma according to the clinical course and pathological findings. We assumed that colon cancer cells can rapidly expand by dedifferentiation, and we diagnosed AFP-producing colon cancer with liver metastases. Despite curative surgery and AC for AFP-producing colon cancer, the patient died of liver and systemic lymph node metastases.
