Local recurrence is one of the remaining problems in rectal and rectosigmoid cancer, and it is sometimes difficult to treat.

Prospective Trial Evaluating the Surgical Anastomosis at One-Year Colorectal Cancer Surveillance: CT Colonography Versus Optical Colonoscopy and Implications for Patient Care.

The aim of this study was to compare the accuracy of CT colonography versus optical colonoscopy for neoplastic involvement at the surgical anastomosis 1 year after curative-intent colorectal cancer resection.

Peritoneal Involvement Is More Common Than Nodal Involvement in Patients With High-Grade Appendix Tumors Who Are Undergoing Prophylactic Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy.

Right hemicolectomy is routinely recommended in patients with histologic findings of high-grade appendix tumors after appendicectomy. Undetected peritoneal disease may be encountered at surgery. In high-grade appendix tumors with disease detected radiologically, complete cytoreduction may not be possible and outcomes poor. For these reasons, we adopted a policy of prophylactic cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Long-term Deleterious Impact of Surgeon Care Fragmentation After Colorectal Surgery on Survival: Continuity of Care Continues to Count.

Surgical care fragmentation at readmission impacts short-term outcomes. However, the long-term impact of surgical care fragmentation is unknown.

Surveillance of Duodenal Polyposis in Familial Adenomatous Polyposis: Should the Spigelman Score Be Modified?

Duodenal polyposis is a manifestation of adenomatous polyposis that predisposes to duodenal or ampullary adenocarcinoma. Duodenal polyposis is monitored by upper GI endoscopies and may require iterative resections and prophylactic radical surgical treatment when malignancy is threatening.

Cancer stem cells revisited.

The cancer stem cell (CSC) concept was proposed four decades ago, and states that tumor growth, analogous to the renewal of healthy tissues, is fueled by small numbers of dedicated stem cells. It has gradually become clear that many tumors harbor CSCs in dedicated niches, and yet their identification and eradication has not been as obvious as was initially hoped. Recently developed lineage-tracing and cell-ablation strategies have provided insights into CSC plasticity, quiescence, renewal, and therapeutic response. Here we discuss new developments in the CSC field in relationship to changing insights into how normal stem cells maintain healthy tissues. Expectations in the field have become more realistic, and now, the first successes of therapies based on the CSC concept are emerging.

The current status of treatment for colorectal cancer in China: A systematic review.

Colorectal cancer (CRC) is one of the most common cancers all over the world, but its epidemiology is obviously different in various regions.

Diagnostic value of using multiplanar reformation images: Case report for rare endotracheal hamartomas.

Pulmonary hamartomas are the most common benign tumor of the lung. Two types of pathologically similar hamartomas exist based on their location. These tumors have a low incidence, are rarely reported and frequently misdiagnosed because of lack of familiarity and/or understanding concerning their imaging features.

Anti-Ma2-associated limbic encephalitis with coexisting chronic inflammatory demyelinating polyneuropathy in a patient with non-Hodgkin lymphoma: A case report.

We report the rare case of a 74-year-old man with anti-Ma2-associated paraneoplastic neurologic syndrome (PNS), and review and analyze the clinical manifestations, diagnosis, and treatment of the disease.

A case report of tongue metastasis from lung squamous cell carcinoma and literature review.

Tongue metastasis from lung cancer is extremely rare, and the prognosis of these patients is rather poor.

Ovarian torsion of mixed epithelial tumor misdiagnosed as a malignancy in postmenopausal woman: A case report.

Adnexal torsion is 1 of the most common emergency gynecological disease. It is more often diagnosed in reproductive age, but rarely in postmenopausal women. The clinical symptoms of adnexal torsion are nonspecific in postmenopausal women. Epithelial ovarian tumors are common in adults, and the risk of malignancy increases with age, especially after menopause. So, it is difficult to diagnose adnexal torsion precisely compared with reproductive women, and most cases of adnexal torsion with postmenopausal women are diagnosed as a malignancy preoperatively. We report a case of ovarian torsion with mixed epithelial tumor misdiagnosed as a malignancy in postmenopausal woman.

Application of neoadjuvant chemotherapy in occult breast cancer: Five case reports.

Although rare, occult breast cancer (OBC) originates from breast tissue. Its primary lesions cannot be identified by clinical examination or imaging; therefore, the diagnosis, treatment, and prognosis remain controversial.

Outcomes of robotic versus laparoscopic surgery for mid and low rectal cancer after neoadjuvant chemoradiation therapy and the effect of learning curve.

Randomized controlled trials have demonstrated that laparoscopic surgery for rectal cancer is safe and can accelerate recovery without compromising oncological outcomes. However, such a surgery is technically demanding, limiting its application in nonspecialized centers. The operational features of a robotic system may facilitate overcoming this limitation. Studies have reported the potential advantages of robotic surgery. However, only a few of them have featured the application of this surgery in patients with advanced rectal cancer undergoing neoadjuvant chemoradiation therapy (nCRT).From January 2012 to April 2015, after undergoing nCRT, 40 patients with mid or low rectal cancer were operated using the robotic approach at our institution. Another 38 patients who were operated using the conventional laparoscopic approach were matched to patients in the robotic group by sex, age, the body mass index, and procedure. All operations were performed by a single surgical team. The clinicopathological characteristics and short-term outcomes of these patients were compared. To assess the effect of the learning curve on the outcomes, patients in the robotic group were further subdivided into 2 groups according to the sequential order of their procedures, with an equal number of patients in each group. Their outcome measures were compared.The robotic and laparoscopic groups were comparable with regard to pretreatment characteristics, rectal resection type, and pathological examination result. After undergoing nCRT, more patients in the robotic group exhibited clinically advanced diseases. The complication rate was similar between the 2 groups. The operation time and the time to the resumption of a soft diet were significantly prolonged in the robotic group. Further analysis revealed that the difference was mainly observed in the first robotic group. No significant difference was observed between the second robotic and laparoscopic groups.Although the robotic approach may offer potential advantages for rectal surgery, comparable short-term outcomes may be achieved when laparoscopic surgery is performed by experienced surgeons. However, our results suggested a shorter learning curve for robotic surgery for rectal cancer, even in patients who exhibited more advanced disease after undergoing nCRT.

Cutaneous sarcoidosis: A retrospective case series and a hospital-based case-control study in Taiwan.

Sarcoidosis is a systemic granulomatous disorder of unknown etiology often involving skin. Studies on cutaneous sarcoidosis and comorbidities are limited. This study is aimed to describe the clinical features of cutaneous sarcoidosis diagnosed in our hospital and to determine the relationships between cutaneous sarcoidosis and comorbidities.This retrospective study evaluates patients with cutaneous sarcoidosis in a tertiary center in Taiwan from 1996 to 2015. The records of 38 patients with cutaneous sarcoidosis were reviewed for clinical characteristics and evaluated by analysis of variance. A 1:4 case-control analysis was conducted with 152 age- and sex-matched controls who underwent biopsy for other benign skin tumors.The male to female ratio was 1:4.4. The average age at diagnosis was 51.7 years. Female patients were on average 13.9 years older than male patients. The correlation of age with gender was statistically significant (P = .037). The most common cutaneous lesions were plaques (47.4%) and confined to the face (71.1%). Of the 38 patients, 26.3% had diabetes mellitus. Age over 40 (P = .014) and female (P = .014) were associated with facial involvement. In the case-control study, a higher percentage of patients with cutaneous sarcoidosis than of control subjects had diabetes mellitus (P = .001), hearing loss (P = .031) and eye diseases (P = .047).The present study demonstrates a striking female predominance and high proportions of facial involvement. Diabetes mellitus, hearing loss, and eye diseases may be associated with Taiwanese patients with cutaneous sarcoidosis.

The association between diabetes/hyperglycemia and the prognosis of cervical cancer patients: A systematic review and meta-analysis.

The predictive roles of diabetes in the prognosis of many types of cancer have been well studied, but its role in predicting the prognosis of cervical cancer is still controversial. The aim of the study is to evaluate the association between diabetes/hyperglycemia and the prognosis of cervical cancer.

Intensity-modulated radiation therapy for patients with 1 to 3 brain metastases in recursive partitioning analysis class 3.

The prognosis is extremely poor for patients with brain metastases in recursive partitioning analysis (RPA) class 3. It is not clear whether dose elevation for brain lesions in addition to whole-brain radiotherapy could improve survival for those patients. This study aimed to assess the efficacy and safety of dose elevation with intensity-modulated radiation therapy (IMRT) for patients with 1 to 3 brain metastases in RPA class 3.From January 2013 to December 2015, 24 patients with 1 to 3 brain metastases in RPA class 3 were included in this study. The median age was 60 (range 41-85) years and the mean graded prognostic assessment (GPA) score was 1.25 (range 0.5-2). Whole-brain radiotherapy (30 Gy) with a simultaneous integrated boost (SIB) to the brain metastases (totaling 40 Gy) was delivered in 10 fractions using IMRT technique. Survival times and overall safety were assessed. The significance of prognostic variables on survival was assessed by both univariate and multivariate analyses.All of the patients completed the planned SIB schedule. The overall response rate was 66.7%. The median survival time (MST) was 8 months for the entire group of patients. The MST was 5 months for patients with a GPA score of 0.5 to 1 (n = 11 patients) and 12 months with a GPA score of 1.5 to 2 (n = 13 patients). No acute or late toxicities greater than grade 2 were detected. Age and subsequent chemotherapy were significantly associated with MST on univariate and multivariate analyses.It is feasible to elevate radiation doses to 40 Gy using the IMRT technique in RPA class 3 patients with 1 to 3 brain metastases without serious toxicities. The preliminary results are encouraging and further studies with larger cohorts are warranted.

Phase 1 study of the anti-CD22 immunotoxin moxetumomab pasudotox for childhood acute lymphoblastic leukemia.

Novel therapies are needed to overcome chemotherapy resistance for children with relapsed/refractory acute lymphoblastic leukemia (ALL). Moxetumomab pasudotox is a recombinant anti-CD22 immunotoxin. A multicenter phase 1 study was conducted to determine the maximum-tolerated cumulative dose (MTCD) and evaluate safety, activity, pharmacokinetics, and immunogenicity of moxetumomab pasudotox in children, adolescents, and young adults with ALL (N = 55). Moxetumomab pasudotox was administered as a 30-minute IV infusion at doses of 5 to 50 µg/kg every other day for 6 (cohorts A and B) or 10 (cohort C) doses in 21-day cycles. Cohorts B and C received dexamethasone prophylaxis against capillary leak syndrome (CLS). The most common treatment-related adverse events were reversible weight gain, hepatic transaminase elevation, and hypoalbuminemia. Dose-limiting CLS occurred in 2 of 4 patients receiving 30 µg/kg of moxetumomab pasudotox every other day for 6 doses. Incorporation of dexamethasone prevented further dose-limiting CLS. Six of 14 patients receiving 50 µg/kg of moxetumomab pasudotox for 10 doses developed hemolytic uremic syndrome (HUS), thrombotic microangiopathy (TMA), or HUS-like events, exceeding the MTCD. Treatment expansion at 40 µg/kg for 10 doses (n = 11) exceeded the MTCD because of 2 HUS/TMA/HUS-like events. Dose level 6B (ie, 50 µg/kg × 6 doses) was the MTCD, selected as the recommended phase 2 dose. Among 47 evaluable patients, an objective response rate of 32% was observed, including 11 (23%) composite complete responses, 5 of which were minimal residual disease negative by flow cytometry. Moxetumomab pasudotox showed a manageable safety profile and evidence of activity in relapsed or refractory childhood ALL. This trial was registered at as #NCT00659425.

Differential Prognostic Value of Metabolic Heterogeneity of Primary Tumor and Metastatic Lymph Nodes in Patients with Pharyngeal Cancer.

We aimed to explore the prognostic value of metabolic heterogeneity of (18)F-FDG uptake in chemoradiotherapy-treated pharyngeal cancer patients.

Gastric Spindle Cell Neuroendocrine Tumor Mimicking Gastrointestinal Stromal Tumor: Unique Morphology and Diagnostic Pitfall.

Gastric neuroendocrine tumors (GNETs) with spindle cell morphology are extremely rare. We present a case of a 49-year-old female patient with a history of systemic lupus erythematosus, Sjogren's syndrome, and gastroesophageal reflux disease. She was initially thought to have a spindle cell gastrointestinal stromal tumor per histological studies of the fundic polypectomy samples. Immunohistochemically, the tumor cells were negative for CD117, and CD34, but positive for chromogranin, synaptophysin, and CD56 with a 6% Ki-67 index, consistent with a spindle cell-type well differentiated neuroendocrine tumor, World Health Organization (WHO) Grade 2. To the best of our knowledge, this is the first case report of a gastric spindle cell neuroendocrine tumor in the English literature.

The Association Between Chemotherapy Immediately Before Nivolumab and Outcomes Thereafter.

We investigated whether the efficacy and type of pre-nivolumab chemotherapy influence outcomes in non-small cell lung cancer patients following nivolumab treatment.

miR-223 and Stathmin-1 Expression in Non-tumor Liver Tissue of Patients with Hepatocellular Carcinoma.

Overexpression of stathmin (STMN1) has been reported for several tumor entities. STMN1 expression correlated with the detection of mutant p53, also suggesting loss-of-function-dependent mechanisms for its accumulation in hepatocellular carcinoma (HCC) cells. On the other hand, miR-223 has been identified as one of the most down-regulated miRNAs in HCC, and its expression was shown to be negatively correlated with STMN1 expression. The aim of this study was to investigate the clinical significance of STMN1 and miRNA-223 expression.

Surgical Resection and Outcome of Synchronous and Metachronous Primary Lung Cancer in Breast Cancer Patients.

Women with breast cancer are at increased risk of subsequent primary malignancies, specifically lung cancer. The aim of this study was to report the frequency of lung cancer in patients with breast cancer, and patients' characteristics and surgical outcomes.

Perioperative Red Blood Cell Transfusion Is Associated with Poor Long-term Survival in Pancreatic Adenocarcinoma.

Perioperative red blood cell transfusion (RBCT) can negatively affect the host's immune system. We investigated the effects of perioperative RBCT on long-term survival among patients with pancreatic ductal adenocarcinoma (PDAC).

Predictive Factors for Poor Progression-free Survival in Patients with Non-small Cell Lung Cancer Treated with Nivolumab.

Nivolumab has shown promising effects in patients with non-small-cell lung cancer (NSCLC) as a second- or later-line treatment. This study aimed to identify patients who would not experience any benefit from nivolumab treatment.

A Proposal for Progression-Free Survival Assessment in Patients with Early Progressive Cancer.

Progression-free survival (PFS), which is evaluated in oncology clinical trials, is determined based on tumor progression evaluated according to an assessment schedule. There is possibly a bias in median PFS and hazard ratio (HR) for PFS depending on the assessment schedule referring to randomized controlled trials (RCTs) in patients with metastatic colorectal cancer.

Febuxostat as a Prophylaxis for Tumor Lysis Syndrome in Children with Hematological Malignancies.
