Purpose: Laparoscopic total gastrectomy (LTG) for gastric cancer is still uncommon because of technical difficulties, especially in esophagojejunostomy (EJ). There are many reports for various laparoscopic procedures of EJ using linear or circular staplers. On the other hands, there has been no report for hand-sewn anastomosis. We report successfully performed intracorporeally hand-sewn EJ after LTG. Materials and Methods: The clinicopathologic data and short-term surgical outcomes of 6 patients who underwent totally laparoscopic total gastrectomy for upper gastric cancer from December 2010 and July 2011 were retrospectively reviewed. Results: The mean age was 66.5 years and mean body mass index (kg/$m^2$) was 24.6. All patients had medical comorbidities. The mean patient ASA score was 2.17. Among the 6 patients, previous abdominal operation was performed for 2 patients and combined operation was performed for 3 patients. The mean blood loss, operation time, and EJ anastomosis time was 130 ml, 379.7 minutes, and 81.5 minutes, respectively. The mean time to first flatus, first oral intake, and postoperative hospital stay was 3.0, 3.0, and 12.5 days, respectively. There was no 30-day mortality case. Postoperative aspiration pneumonia and multiple periventricular lacunar infarctions developed in 1 patient. There were no anastomosis-related complications and other major surgical complications. Conclusions: When the intracorporeal anastomotic technique becomes popular in LTG the intracorporeally hand-sewn EJ may be accepted as one method among the various laparoscopic procedures of EJ.

Trichoepithelioma is a benign hair follicle tumor that can undergo malignant transformation into basal cell carcinoma in rare cases. Due to the similar clinical and histological features of trichoepithelioma and basal cell carcinoma, distinguishing between these types of tumors can be a diagnostic challenge. Punch biopsy obtains only a small sample of the entire lesion, and thus inherently involves a risk of misdiagnosis between histologically similar diseases. Therefore, if the possibility of misdiagnosis can reasonably be suspected, clinicians should conduct an excisional biopsy or immunohistochemical staining (e.g., CD10 and Bcl-2) to ensure an exact diagnosis. Although trichoepithelioma is benign, the surgical excision of solitary trichoepithelioma should be considered in order to avoid the possibility of malignant transformation, which has occasionally been documented for multiple familial trichoepitheliomas. Herein, we report a case that was initially misdiagnosed as trichoepithelioma before ultimately being diagnosed as basal cell carcinoma through excision and immunohistochemical staining.

Purpose: The purpose of this study was to test the mediating effect of social support and resilience on the relationship between symptom distress and coping in young Korean breast cancer survivors. Methods: A purposive sample of 209 young breast-cancer survivors (mean age 39.9) was recruited for a cross-sectional survey, and the data were collected between June and October 2015. The instruments used in this study were the Memorial Symptom Assessment Scale-Short Form, the Multidimensional Scale of Perceived Social Support, 10-item Connor-Davidson Resilience Scale, and Cancer Coping Questionnaire. The collected data were then analyzed using the SPSS 23.0 and AMOS 23.0 programs. Results: Symptom distress was found to have a significant indirect effect on coping (beta=-.32, p=.002), but not a significant direct effect (beta=.06, p=.577). Additionally, based on the values obtained for the squared multiple correlation, symptom distress, social support, and resilience were found to explain 46.4% of the total variance of coping. Conclusion: Based on the results of this study, it can be suggested that in order to enhance young breast cancer survivors' ability to cope with the distress they commonly feel, intervention methods that strengthen resilience and provide social support should be developed and made available to them.

Cutaneous squamous cell carcinoma (SCC) is the second most common skin malignancy. This report describes the case of an unusual extensive SCC involving the whole hemiface, which required reconstruction with a combination of a dual vascular free transverse rectus abdominis muscle (TRAM) flap and a skin graft. A 79-year-old woman visited our hospital with multiple large ulcerated erythematous patches on her right hemiface, including the parieto-temporal scalp, bulbar and palpebral conjunctiva, cheek, and lip. A preliminary multifocal biopsy was performed in order to determine the resection margin, and the lesion was resected en bloc. Orbital exenteration was also performed. A free TRAM flap was harvested with preserved bilateral pedicles and was anastomosed with a single superior thyroidal vessel. The entire TRAM flap survived. The final pathological examination of the resected specimen confirmed that there was no regional nodal metastasis, perineural invasion, or lymphovascular involvement. The patient was observed for 6 months, and there was no evidence of local recurrence. Usage of a TRAM flap is appropriate for hemifacial reconstruction because the skin of the abdomen matches the color and pliability of the face. Furthermore, we found that the independent attachment of two extra-flap anastomoses to a single recipient vessel can safely result in survival of the flap.

Objectives : A hospital-based case-control study was conducted to evaluate the role of obesity in the development of colorectal cancer. Methods : Three hundred and twenty four histologically confirmed female colorectal cancer cases and 26,998 non-cancer controls were selected from patients invited to the Aichi Cancer Center, Nagoya, Japan between 1989 and 1995. Information concerning demographic factors, medical history, family medical history, reproductive factors and dietary factors were obtained from self-administered questionnaires and medical records. The effects of weight and body mass index to colorectal cancer were examined using multiple logistic regression to control for other risk factors. Results : There was no significant association between female colorectal cancer and obesity. Heavier weight adjusted for height or body mass index did not increase the risk of colorectal cancer. Conclusions : These results suggest that there is no association between colorectal cancer risk and obesity in women.

The purpose of this retrospective study was to provide additional data on the use of toceranib in a wide variety of tumor types in small breed dogs, especially < 8 kg (except 5 dogs). This was a retrospective study of 31 dogs with malignant tumors treated with a 2.5 mg/kg median dose of toceranib (Palladia; Zoetis, USA) on a Monday-Wednesday-Friday schedule. Clinical benefit was observed in 13 of 15 dogs (86.7%, 3 with complete response, 4 with partial response, 6 with stable disease) with gross disease. Distant metastasis, response to treatment, and treatment setting were significantly associated with survival time. Negative prognostic factors were multiple chemotherapy and distant metastasis (affecting progression-free survival [PFS]), surgery, regional enlarged lymph nodes, underlying disease, and toxicity (affecting median survival time [MST]). Positive prognostic factors were epithelial and round cell tumor (affecting PFS), epithelial tumor, microscopic disease, no evidence of disease response, and stable disease (MST). In conclusion, a clinical benefit from toceranib treatment was noted in most of the dogs with gross disease in our study. This study suggested that the toceranib is probably selective treatment to various tumor types in small breed dogs.

Objective : Pituitary adenomas frequently extend into the suprasellar space. After a suprasellar tumor is removed, the superiorly extended arachnoid becomes redundant and sinks down into the intrasellar space which often hiders visualization and accessibility to the hidden space behind the evaginated arachnoid. We introduced arachnoid remodeling by clipping technique, and evaluated its usefulness and safety during TSS. Methods : Total 223 patients who underwent arachnoid remodeling with our new clipping technique were included. Redundant arachnoid was clipped along the dural edge with multiple 2.6-mm titanium clips until the redundant arachnoid membrane no longer blocked the surgical route. To check for possible deterioration of hormonal function by this technique, we assessed anterior pituitary function of 166 patients who underwent arachnoid remodeling by clipping and compared this with those of other 429 control patients. Results : Our technique greatly enhanced the accessibility and visualization of intrasellar and parasellar spaces, both of which are generally hindered by redundant arachnoid during transsphenoidal surgery (TSS). We found no difference in anterior pituitary function between a clip-assisted arachnoid remodeling group and the control group, implying that this technique does not result in hypopituitarism. Conclusion : During TSS for pituitary adenomas with suprasellar extension, arachnoid remodeling by clipping technique is very useful and convenient for the management of the redundant arachnoid membrane to enhance visualization and surgical accessibility.

Janus kinase 2 (JAK2), a non-receptor tyrosine kinase, is a critical component of cytokine and growth factor signaling pathways regulating hematopoietic cell proliferation. JAK2 mutations are associated with multiple myeloproliferative neoplasms. Although physiological and pathological functions of JAK2 in hematopoietic tissues are well-known, such functions of JAK2 in the nervous system are not well studied yet. The present study demonstrated that JAK2 could negatively regulate neuronal differentiation of mouse embryonic stem cells (ESCs). Depletion of JAK2 stimulated neuronal differentiation of mouse ESCs and activated glycogen synthase kinase 3β, Fyn, and cyclin-dependent kinase 5. Knockdown of JAK2 resulted in accumulation of GTP-bound Rac1, a Rho GTPase implicated in the regulation of cytoskeletal dynamics. These findings suggest that JAK2 might negatively regulate neuronal differentiation by suppressing the GSK-3β/Fyn/CDK5 signaling pathway responsible for morphological maturation.

Palisading encapsulated neuroma is a rare, benign, cutaneous nerve sheath tumor. It usually occurs as an asymptomatic solitary skin-colored papule and commonly affects the nose and cheeks. Sometimes, it involves other sites, including the shoulder, upper arm, and trunk, but rarely involves the oral mucosa, including that of the lip. In our case, a 63-year-old female patient complained of a pinkish rubbery nodule on her lower lip. Histopathologic examination demonstrated a well-circumscribed nodule encapsulated by connective tissue stroma in the dermis. The nodule consisted of palisading spindle-shaped tumor cells with wavy and basophilic nuclei. The cells were arranged in streaming fascicles with multiple clefts and were strongly positive for S-100 proteins. To our knowledge, only three cases of palisading encapsulated neuroma on the lower lip have been reported in the Korean literature. Herein, we report a rare case of an oral palisaded encapsulated neuroma.

Purpose: This study aimed to identify attitudes toward advance directives (ADs) among female cancer patients and factors related to ADs. Methods: The study was conducted at a university hospital in Seoul from September 19, 2020, to January 20, 2021. The participants were 153 patients diagnosed with gynecological cancer or breast cancer. Data were collected using questionnaires and included general characteristics, disease- and AD-related characteristics, knowledge and attitudes about ADs, and attitudes about dignified death. Data were analyzed using the t-test, analysis of variance, and multiple regression analysis. Results: Only 2% of the participants completed ADs. The mean score for attitudes toward ADs was 3.30, indicating a positive knowledge and attitude toward dignified death. The factors related to attitudes toward ADs were attitudes toward dignified death (𝛽=0.25, P=0.001), experience discussing life-sustaining treatment (𝛽=0.17, P=0.037), preferred time to have a consultation about ADs (𝛽=0.19, P=0.046), intention to write ADs (𝛽=0.15, P=0.038), and Eastern Cooperative Oncology Group Performance Status (𝛽=-0.37, P<0.001). The explanatory power of these variables for attitudes toward ADs was 38.5%. Conclusion: Overall, patients preferred to have a consultation about ADs when they were still active, mentally healthy, and able to make decisions. Education about ADs should be provided to patients on the first day of hospitalization for chemotherapy or while awaiting treatment in an outpatient setting so patients can write ADs and discuss them with family and friends.
