[Efficacy of early interdisciplinary palliative care based on WARM model in non-small-cell lung cancer].

Objective: To assess the therapeutic effect of the early interdisciplinary palliative care based on WARM model (whole, assessment, revaluation, management) on the quality of life, psychological state, pain and nutritional status in patients with non-small-cell lung cancer (NSCLC). Methods: A total of 60 patients from Chongqing University Cancer Hospital with newly diagnosed advanced NSCLC from Oct 15, 2019 to Jun 12, 2020 were enrolled. According to the method of random number table, the patients were divided into two groups: standard oncologic care group (SC, n=30) and early palliative care group (EPC, n=30). SC group only received standard oncological care, while EPC group received standard oncological care and additional comprehensive treatment from a MDT consisted of medical oncologists, palliative care nurses, dietitians and psychologists. The quality of life [functional assessment of cancer therapy-lung (FACT-L) scale], psychological state [hospital anxiety and depression scale (HADS) and patient health questionnaire-9 (PHQ-9)], nutritional status [patient-generated subjective global assessment (PG-SGA)], and cancer pain status [numerical rating scale (NRS)] were observed and compared between the two groups before and after the 6 months treatment, respectively. Results: A total of 45 patients completed 6 months treatment, including 24 males and 21 females, aged 38-82 (60.5±1.7), with 23 patients in the EPC group and 22 patients in the SC group. Patients assigned to EPC group had a better quality of life than those assigned to SC group [FACT-L scale: (122.3±1.6) vs (111.8±2.1), P<0.001]. Fewer patients had anxiety and depressive symptoms in the EPC group than those in the SC group [HADS anxiety subscale: (1.1±0.3) vs (2.9±0.4), P<0.001; HADS depression subscale: (0.7±0.3) vs (3.6±0.4), P<0.001]. The PHQ-9 results showed that 100.0% (23/23) patients were free of depression in the EPC group, while 45.5% (10/22) patients were free of depression in SC group (P<0.001). Furthermore, patients in the EPC group had a better nutritional status [moderate malnutrition: 60.9% (14/23); no malnutrition: 39.1% (9/23)] than those in the SC group [severe malnutrition: 40.9% (9/22); moderate malnutrition: 50.0% (11/22); no malnutrition: 9.1% (2/22)] (P<0.001). There was no significant difference in NRS score between EPC group and SC group (P=0.140). Conclusion: Early interdisciplinary palliative care based on WARM model can improve the quality of life, psychological state and nutritional status in NSCLC patients.

Structural difference analysis of adult's intestinal flora basing on the 16S rDNA gene sequencing technology.

OBJECTIVE: Through 16S rDNA technology, we aimed at separating adults aging 20-50 years old into a few groups and processing the high-throughput sequencing analysis, in order to explore the features and differences of intestinal flora in each age group in a microcosmic perspective. PATIENTS AND METHODS: 120 stool specimens were collected strictly in accordance with acceptance criteria and exclusion criteria. 49 subjects aging 20-29 years old (Group AGE1), 51 subjects aging 30-39 years old (Group AGE2), and 20 subjects aging 40-49 years old (Group AGE3) were divided into 3 groups. Bacteria DNA from fresh stool specimens of 3 groups were abstracted. Illumina MiSeq high-throughput sequencing platform was applied to process 16S rDNA sequencing in Area 338F_806R for intestinal flora detection. I-Sanger Bio-cloud platform was applied for the analysis of intestinal flora structure changes in phylum level and genus level. RESULTS: Among the age of 20-50, with older age, the abundance of intestinal flora decreased among healthy adults more than 40 years old. In addition, the diversity and sample dispersion of intestinal flora is significantly different from people among 20-40 years old. The decrease ratio of Firmicutes/Bacteroidetes indicated that as the age grows, glucose tolerance might decrease. Comparing with people among 20-40 years old, the amount of Bifidobacterium and Eubacterium in people over 40 years old have significantly decreased. The decrease of Bifidobacterium and Eubacterium may increase the risks of cognitive impairment and lower the anti-inflammation and anti-cancer efficacy in human body, respectively. Subdoligranulum relates to poor metabolism and chronic inflammation and it happens more in people aged over 40 than young people who are among 20-40 years old. CONCLUSIONS: There are differences in the intestinal flora of healthy adults aged 20-50. Effective intervention of the intestinal flora may play a role in delaying aging and preventing diseases.

[Clinical study on bilamina cortical grafting technique for reconstruction of severely atrophic alveolar ridges in anterior maxillae].

Objective: To evaluate the efficacy and long-term outcome of the bilaminar cortical wall building grafting technique for reconstruction of vertical and horizontal alveolar ridge defects in the esthetic zone. Methods: The retrospective study was conducted between January, 2007 and December, 2015. The sample was composed of 24 patients who received bilaminar cortical wall building augmentation in the esthetic zone in Department of Fourth Clinical Division, Peking University School of Stomatology. The 24 patients (11 female and 13 male) had age of (37.8±13.4) years (20-54 years). A bone block harvested from the lateral aspect of the mandibular ramus was bisected into two cortical laminae, which were then used to reconstruct the buccal and palatal walls of an alveolar ridge defect. The inter-laminar space was filled with particulate autogenous bone and the whole graft was covered with anorganic bone graft and collagen membrane. Bone width and vertical measurements were measured at the time of surgery and reentry surgery. Integration of the graft, implant survival rates and complications were recorded. Results: Overall, 24 patients with 35 sites who were included were followed for (7.1±1.9) years. Graft integration (24/24) and implant survival rates (35/35) were determined as 100%. The average horizontal and vertical bone gain was (6.47±2.46) and (5.01±1.12) mm with resorption rates of 9.0% and 10.9%, respectively. One patient showed soft-tissue dehiscence with peri-implant mucositis were observed 9 years after surgery. More than 1.5 mm of buccal bone plate were observed using cone beam computed tomography. Conclusions: This technique was effective and reliable for three-dimensional reconstruction of severely atrophic alveolar ridges in anterior maxillae. Autogenous graft combined with coverage by allogeneic bone graft and collagen membrane provided successful augmentation with low bone resorption.

Automated Skeletal Classification with Lateral Cephalometry Based on Artificial Intelligence.

Lateral cephalometry has been widely used for skeletal classification in orthodontic diagnosis and treatment planning. However, this conventional system, requiring manual tracing of individual landmarks, contains possible errors of inter- and intravariability and is highly time-consuming. This study aims to provide an accurate and robust skeletal diagnostic system by incorporating a convolutional neural network (CNN) into a 1-step, end-to-end diagnostic system with lateral cephalograms. A multimodal CNN model was constructed on the basis of 5,890 lateral cephalograms and demographic data as an input. The model was optimized with transfer learning and data augmentation techniques. Diagnostic performance was evaluated with statistical analysis. The proposed system exhibited >90% sensitivity, specificity, and accuracy for vertical and sagittal skeletal diagnosis. Clinical performance of the vertical classification showed the highest accuracy at 96.40 (95% CI, 93.06 to 98.39; model III). The receiver operating characteristic curve and the area under the curve both demonstrated the excellent performance of the system, with a mean area under the curve >95%. The heat maps of cephalograms were also provided for deeper understanding of the quality of the learned model by visually representing the region of the cephalogram that is most informative in distinguishing skeletal classes. In addition, we present broad applicability of this system through subtasks. The proposed CNN-incorporated system showed potential for skeletal orthodontic diagnosis without the need for intermediary steps requiring complicated diagnostic procedures.

Donor-derived marrow mesenchymal stromal cell co-transplantation following a haploidentical hematopoietic stem cell transplantation trail to treat severe aplastic anemia in children.

Haploidentical hematopoietic stem cell transplantation (haplo-HSCT) is associated with an increased risk of graft failure and severe graft-versus-host disease (GVHD). Recent studies have shown that mesenchymal stromal cells (MSCs) display potent immunosuppressive effects and can support normal hematopoiesis. In a multi-center trial, we co-transplanted culture-expanded donor-derived bone marrow MSCs (BM-MSCs) into 35 children with severe aplastic anemia (SAA) undergoing haplo-HSCT. All 35 patients (100%) achieved hematopoietic reconstitution and showed sustained full donor chimerism. The median time for myeloid engraftment was 14 days (range 10-22 days), while that for platelet engraftment was 18 days (range 9-36 days). The incidence of grade II-IV acute GVHD and chronic GVHD was 25.71 and 22.86%, respectively. The overall survival rate was 85.71% with a median of 22 months (range 3.5-37 months). The combined transplantation of haploidentical HSCs and BM-MSCs into children with SAA without an HLA-identical sibling donor is relatively safe and may represent an effective new therapy to improve survival rates and reduce the risk of graft failure.

[Analysis of radiation workers health status in a city].

Objective: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Methods: To investigate the health status of radiation workers in a city and provide evidence for the health management of radiation workers. Results: The majority of radiation workers are engaged in diagnostic radiology, male is more than female. The abnormal rate of micronuclear (0.59‰) and chromosome aberration (0.47%) was highest in nuclear medicine workers. The abnormal rate of micronuclear and chromosome aberration was similar with interventional and diagnostic radiology. Expect for micronuclear (χ(2)=32.945, P<0.01) and chromosome aberration (χ(2)=75149.737, P<0.01) , other radiation sensitive indicators have no difference. The abnormal rate of thyroid function (18.8%) (χ(2)=12.084, P<0.01) , micronuclear (0.25‰) (χ(2)=57.359, P<0.01) , chromosome aberration (0.08%) (χ(2)=17.209, P<0.01) in group whose service length exceeding 20 years was higher than other service length groups. There is no statistical difference in other radiation sensitive indicators among different service length group. Conclusion: Long-term low doses of ionizing radiation could affect radiation worker's health, expecially radiation workers engaged in nuclear medicine and radiotherapy. We must pay attention to occupaitonal health care and management to ensure radiation worker's health.

[Analysis of risk factors of 19 fractured implants].

Objective: To analyze the incidence and possible risk factors of 19 fractured implants out of 8 468 implants in 3 184 cases. Methods: During the 22-year clinical practice, clinical records of 18 patients with 19 fractured implants in 3 184 cases with 8 468 implants were analyzed to determine the following factors: location of the fractured implants, prosthodontics option, date of implant fracture, dimensions of fractured implants, complications prior to implant fracture and parafunctional habit. An evaluation of fractured implants was performed to identify possible factors that may predispose an implant to a higher risk of fracture. Results: Overall, the average duration of service of the implants was (7.0±4.5) years. Implant fracture occurred in 7 Camlog implants, 7 Nobel replace implants, 3 Ankylos implants and 2 Brånemark implants. No Thommen implant fractures were recorded. Amongst the 19 fractured implants, 8 occurred at the thinnest wall portion of the implant neck, 8 at the end of screw and 3 at the self-tapping thread region. All fractures were observed after functional loading. Furthermore, 9/19 (47.4%) of fractures occurred in the maxilla, indicating similar incidence rates in both arches (P=0.065). Most of fractures (16/19) occurred in the molar region and 18/19 in single implant-supported restorations. Totally 17 cases had received metal occlusal restorations. In 6 cases (35.5%), previous bone destruction apically extending to the level of implant fracture was documented before any clinical signs of fracture. Three fractured implants were removed and simultaneously re-implanted with larger-diameter implants, while the rest of the cases were left to heal, followed by a second-stage surgery. Conclusions: Within the limitation of this analysis, the study demonstrated that appropriate implant-abutment connection design, implant diameter, prosthetic strategy and bone resorption are crucial to the long-term performance of implants. There is no significant difference of fractures rates in both archs.

Transoral and endoscope-assisted transoral approaches to resecting benign tumours of the parapharyngeal space located in the medial portion of the carotid sheaths and extending toward the skull base: our experience.

OBJECTIVE: Various surgical approaches have been described to remove tumours in the parapharyngeal space. This study investigated the feasibility of a transoral approach in the surgical management of parapharyngeal space benign tumours located in the medial portion of the carotid sheaths and extending toward the skull base. METHODS: Thirty-two patients were selected and underwent a transoral or an endoscope-assisted transoral approach in the surgical management of parapharyngeal space benign tumours located in the medial portion of the carotid sheaths. Medical photographs were used. RESULTS: All patients underwent complete resection of their lesions via a transoral or endoscope-assisted transoral approach. None of the patients demonstrated residual or recurrent neoplasms, either clinically or radiographically, during their follow up. CONCLUSION: Based on our studies, we assert that transoral and endoscope-assisted transoral approaches are suitable in managing parapharyngeal space benign tumours located in the medial portion of the carotid sheaths and extending toward the skull base.

The association of fruit and vegetable consumption with changes in weight and body mass index in Chinese adults: a cohort study.

OBJECTIVES: Findings regarding the benefits of fruit and vegetables (FV) on weight control are inconsistent and little is known among Chinese populations. Therefore, we examined the relationship between change in FV consumption, weight, and change in body mass index (BMI) among Chinese adults, participants of the China Health and Nutrition Survey (CHNS). STUDY DESIGN: A prospective cohort study. METHODS: Two waves of CHNS conducted in 2006 and 2011 were used. Continuous FV consumption increase was considered as the exposure and changes in weight and BMI as outcomes. Change in FV consumption was categorized into quintiles. Analysis of covariance and multiple linear regression models, after controlling for potential confounders such as energy intake, physical activity, and smoking, were used to describe the relationship between change in FV consumption and change in weight and BMI. RESULTS: A total of 4357 participants aged 18-65 years were included in this study. The respective weight and BMI gains in male individuals were 1.81 kg and 0.73 kg/m2 in the fifth quintile of FV change relative to individuals in the first quintile (3.67 kg for weight gain and 1.48 kg/m2 for BMI gain). An increase in FV consumption by 100 g was associated with a 211 g weight loss (B = -2.11; 95% confidence interval [CI], -3.34, -0.89, P < 0.001) and a decrease in BMI by 0.94 kg/m2 (B = -0.94; 95% CI, -1.36, -0.46, P < 0.001) in men; and a 140 g weight loss (B = -0.14; 95% CI, -0.97, 0.69, P = 0.74) and a decrease in BMI by 0.29 kg/m2 BMI (B = -0.29; 95% CI, -0.63, 0.06, P = 0.11) in women. CONCLUSIONS: Increase in FV consumption was associated with statistically significant weight loss and decrease in BMI among Chinese men, and, although suggested, weight loss among women was not significant. Considering the protective effect of FV on human health, increasing FV consumption in the Chinese population is recommended.

Autotransplantation of third molars with completely formed roots into surgically created sockets and fresh extraction sockets: a 10-year comparative study.

The aim of this study was to analyze and compare the long-term clinical outcomes of mature third molar autotransplantation in surgically created sockets and fresh extraction sockets with regard to survival and functional success rates. A total of 65 third molars with completely formed roots were autotransplanted in 60 patients (average age 33.1 years). Thirty-six of the teeth were autotransplanted into surgically created sockets with or without guided bone regeneration (GBR; delayed autotransplantation), while 29 were autotransplanted into fresh extraction sockets (immediate autotransplantation; control group). All patients underwent annual clinical and radiographic examinations (average follow-up 9.9 years, range 7-13 years). The survival rates for the control, GBR, and no GBR groups were 93.1%, 95.2%, and 80.0%, respectively, with no significant differences among the groups. There were no statistically significant differences among the groups with regard to the frequency of inflammatory root resorption or root ankylosis. Age did not influence the clinical outcomes. These results suggest that the autotransplantation of third molars with completely formed roots is effective in both surgically created and fresh extraction sockets and provides a high long-term success rate if cases are selected and treated appropriately.

[Chromosome aberration and micronucleus frequency in peripheral blood lymphocytes in radiation workers].

OBJECTIVE: To investigate chromosome aberration and micronucleus frequency in peripheral blood lymphocytes in workers engaged in radiation for a long time, to reduce occupational hazard caused by ionizing radiation, and to further strengthen health surveillance. METHODS: A total of 366 members of medical staff engaged in radiation work who underwent physical examinations in Hangzhou Hospital of Prevention and Treatment of Occupation Diseases from 2014 to 2015 were enrolled as radiation group, consisting of staff engaged in X-ray diagnosis, diagnostic radiology, radiotherapy, and interventional radiology. Another 100 members of medical staff without exposure to radiation were enrolled as control group. Whole blood culture was used to measure chromosome aberration and micronucleus frequency in peripheral blood lymphocytes. RESULTS: The radiation group had a significantly higher rate of chromosome aberration than the control group (0.30% vs 0.09% , χ(2)= 13.43, P<0.01), as well as a significantly higher micronucleus frequency than the control group (2.09‰ vs 0.08‰, χ(2)=74.4, P<0.01). The abnormal rates of chromosome aberration and micronucleus showed no significant differences across radiation workers with different working years (P>0.05). The staff engaged in X-ray diagnosis, diagnostic radiology, radiotherapy, and interventional radiology had rates of chromosome aberration of 0.25%, 0.25%, 0.23%, and 0.41%, respectively, which showed a significant difference between the staff at these four posts (χ(2)=8.22, P<0.05); the micronucleus frequencies in the staff at these four posts were 1.36‰, 1.28‰, 1.14‰, and 3.79‰, respectively, and showed a significant difference between the staff at these four posts (χ(2)=251.09, P<0.01). CONCLUSION: Radiation workers are exposed to lowdose ionizing radiation for a long time, which may cause significant increases in the rate of chromosome aberration and micronucleus frequency in peripheral blood lymphocytes.

CTC1 increases the radioresistance of human melanoma cells by inhibiting telomere shortening and apoptosis.

Melanoma has traditionally been viewed as a radioresistant cancer. However, recent studies suggest that under certain clinical circumstances, radiotherapy may play a significant role in the treatment of melanoma. Previous studies have demonstrated that telomere length is a hallmark of radiosensitivity. The newly discovered mammalian CTC1­STN1-TEN1 (CST) complex has been demonstrated to be an important telomere maintenance factor. In this study, by establishing a radiosensitive/radioresistant human melanoma cell model, MDA-MB-435/MDA-MB­435R, we aimed to investigate the association of CTC1 expression with radiosensitivity in human melanoma cell lines, and to elucidate the possible underlying mechanisms. We found that CTC1 mRNA and protein levels were markedly increased in the MDA-MB­435R cells compared with the MDA-MB­435 cells. Moreover, the downregulation of CTC1 enhanced radiosensitivity, induced DNA damage and promoted telomere shortening and apoptosis in both cell lines. Taken together, our findings suggest that CTC1 increases the radioresistance of human melanoma cells by inhibiting telomere shortening and apoptosis. Thus, CTC1 may be an attractive target gene for the treatment of human melanoma.

Lipomembranous changes associated with systemic lupus erythematosus.

Lipomembranous changes are distinctive histopathological findings, which include the presence of cystic cavities lined by crenulated, hyaline membranes in adipose tissue. It is likely that ischaemia is fundamental to the development of these lesions, and that lipomembranes are formed from the products of degenerating fat cell membranes by some unknown mechanism. Such changes may be seen, although rarely, in many types of subcutaneous inflammatory processes. However, an association with systemic lupus erythematosus (SLE) is rare. We report a patient with SLE who had the histological features of lipomembranous changes associated with vasculopathy.

Long-term follow-up of autogenous canine transplants with application of guided bone regeneration.

The aim of this study was to evaluate the aesthetics and outcome of autotransplantation of impacted canines unsuitable for orthodontic realignment using a combination of surgery with guided bone regeneration and orthodontic treatment. Ten severely impacted canines in nine consecutive patients (mean age 14.8 years) were included. The recipient mesiodistal space was created orthodontically and the recipient socket prepared using dental implant drills. Following transplantation, bone defects were grafted using guided bone regeneration, teeth were aligned and occlusions adjusted orthodontically. Patients were followed-up every 6 months for an average of 7.1 years (range 2-11 years). The mean pink aesthetic score was 13.33 ± 0.87. Pocket depths were less than 3 mm. Radiographic examination showed an uninterrupted periodontal space and lamina dura in seven cases, unclear periodontal space in two, and replacement resorption in one case. The analysis showed that canine transplantation combined with guided bone regeneration and orthodontic treatment gives acceptable and predictable aesthetic results.

Apoptotic effect of dibenzylideneacetone on oral cancer cells via modulation of specificity protein 1 and Bax.

OBJECTIVE: Dibenzylideneacetone (DBA), an analogue of curcumin, has been shown to have potential anticancer effects against several cancers. However, the molecular mechanism underlying anticancer activity of DBA has not been well established yet. In this study, we investigated the function and molecular mechanism of DBA in human oral cancer cells. MATERIALS AND METHODS: The growth-inhibitory and apoptotic effects and related signaling pathways of DBA were evaluated using trypan blue exclusion assay, 4'-6-diamidino-2-phenylindole staining, Western blot analysis, siRNA, and reverse transcription-polymerase chain reaction. RESULTS: DBA inhibited cell growth and induced apoptosis, as evidenced by PARP cleavage, activation of caspase-3, and nuclear condensation. DBA also decreased specificity protein 1 (Sp1) expression through facilitating protein degradation. In addition, DBA enhanced the induction of pro-apoptotic protein Bax, resulting in their conformational change, translocation into mitochondrial outer membrane, and its oligomerization. The down-regulation of Sp1 by siRNA targeting Sp1 and mithramycin A increasingly activated Bax to trigger apoptosis. Moreover, DBA-induced growth inhibition and apoptosis in various human oral cancer cell lines were associated with Sp1 down-regulation and induction of Bax. CONCLUSION: These findings suggest that DBA may be a potential anticancer drug candidate to induce apoptosis through down-regulation of Sp1 in human oral cancer.

Clinical characteristics and biomarkers of breast cancer associated with choline concentration measured by 1H MRS.

This study investigated the association between the total choline (tCho) concentration and the clinical characteristics and biomarker status of breast cancer. Sixty-two patients with breast cancer, 1.5 cm or larger in size on MR images, were studied. The tCho concentration was correlated with the MRI features, contrast enhancement kinetics, clinical variables and biomarkers. Pairwise two-tailed Spearman's nonparametric test was used for statistical analysis. The tCho concentration was higher in high-grade than moderate-/low-grade tumors (p = 0.04) and in tumors with higher K(trans) and k(ep) (p < 0.001 for both). The association of tCho concentration with age (p = 0.05) and triple negative biomarker (p = 0.09) approached significance. tCho was not detected in 17 patients, including 15 with invasive ductal cancer and two with infiltrating lobular cancer. Fifteen of the 17 patients had moderate- to low-grade cancers, and 11 had human epidermal growth factor-2-negative cancer, suggesting that these two factors might lead to false-negative choline. Higher tCho concentration in high-grade tumors and tumors with higher K(trans) and k(ep) indicates that choline is associated with cell proliferation and tumor angiogenesis. The higher choline level in younger women may be caused by their more aggressive tumor type. The results presented here may aid in the better interpretation of (1)H MRS for the diagnosis of breast lesions.

An audit of nephroureterectomy for upper tract urothelial carcinoma.

BACKGROUND: The boundary of nephroureterctomy has been revisited and lymph node dissection has been recommended recently. We investigated the role of synchronous ipsilateral adrenalectomy in treating patients with upper tract urothelial carcinoma. METHODS: 110 patients with clinically localized upper tract urothelial carcinoma treated by nephroureterectomy and bladder cuff resection were retrospectively evaluated. 70 patients underwent nephroureterectomy without concomitant ipsilateral adrenalectomy, whereas nephroureterectomy and ipsilateral adrenalectomy was performed in other 40 patients. Cancer specific, metastasis and local recurrence free survival during a follow-up of median 46 months were analyzed. RESULTS: No patient had adrenal metastasis among the 40 adrenalectomized patients. A total of 4 patients developed local recurrences; including 1 of the 70 adrenalectomy-sparing and 3 of the 40 adrenalectomized patients (p = 0.102, chi-square test). Five patients with adrenalectomy and four without adrenalectomy had distant metastases (p = 0.212, chi-square test). The five-year local recurrence free survival (p = 0.09, log-rank test), metastasis-free survival (p = 0.292, log-rank test), and cancer-specific survival (p = 0.117, log-rank test) did not have significant difference between both groups. CONCLUSIONS: This is the only study in recent 2 decades to evaluate the necessity of synchronous adrenalectomy in treating localized upper tract urothelial carcinoma. Adrenal-sparing nephroureterectomy seems justified for clinically localized upper tract urothelial carcinoma.

Urachal adenocarcinoma following kidney transplantation: the first case report.

A 53-year-old man who underwent successful kidney transplantation for stage 5 chronic kidney disease presented to our clinic with intermittent painless gross hematuria. Urachal adenocarcinoma, stage III A by Sheldon system, was diagnosed after serial histopathologic and radiological studies. The patient was treated with extended partial cystectomy, en bloc resection of urachus and umbilicus, pelvic lymphadenectomy, and ileocystoplasty. There were no complications seen in this patient. Neither urachal adenocarcinoma recurrence, metastasis, nor de novo uroileal cancer developed during 48-month follow-up. His reconstructed bladder functioned efficiently, without compromising the transplanted kidney function. Our case demonstrated that conservative surgery and augmentation ileocystoplasty could be offered to kidney transplant recipients with localized urachal carcinoma.
