PURPOSE: We analyzed the RESULTS of the GnRH stimulation test to assess its usefulness as a predictor for testicular dysfunction in adolescent varicocele. MATERIALS AND METHODS: We studied 20 adolescents with unilateral varicocele from January 1998 to January 2001. Eight patients were grade II and 12 were grade III. Testicular volume was measured using an orchidometer. The responses of the gonadotropins to GnRH stimulus were compared between grade II and III patients. All patients had varicocelectomy and 7 were followed up. RESULTS: After GnRH stimulus, all patients except one showed excessive response in LH and FSH. LH response(8-fold greater than the baseline) was more exaggerated than that of FSH(1.8-fold greater than the baseline). The 12 patients of grade III varicocele presented greater excessive responses in LH and FSH to GnRH stimulus than those of grade II(p>0.05). After surgical treatment, the exaggerated gonadotropin response to GnRH was not normalized. But the response was less exaggerated, suggesting an improvement of testicular dysfunction. CONCLUSIONS: In this study, the grade of the varicocele was correlated with the excessive responses of the gonadotropins to the GnRH stimulus. Nevertheless, we suggest that the deterioration of the testicular function in adolescents with varicocele was a progressive phenomenon. We think that the GnRH stimulation test could be useful in assessing the testicular dysfunction in adolescent varicocele patients.

Background/Aims: AT-rich interactive domain 1A (ARID1A) is frequently mutated in gastric cancer (GC), especially Epstein-Barr virus (EBV)-associated and microsatellite instability high GC.The loss of ARID1A expression has been reported as a poor prognostic marker in GC. However, the relationships between ARID1A alteration and EBV-associated and microsatellite instability high GC, which are known to have a favorable prognosis, has hampered proper evaluation of the prognostic significance of ARID1A expression in GC. We aimed to analyze the true prognostic significance of ARID1A expression by correcting confounding variables. Methods: We evaluated the ARID1A expression in a large series (n=1,032) of advanced GC and analyzed the relationships between expression pattern and variable parameters, including clinicopathologic factors, key molecular features such as EBV-positivity, mismatch repair protein deficiency, and expression of p53 and several receptor tyrosine kinases including human epidermal growth factor receptor 2, epidermal growth factor receptor, and mesenchymal-epithelial transition factor. Survival analysis of the molecular subtypes was done according to the ARID1A expression patterns. Results: Loss of ARID1A expression was found in 52.5% (53/101) of mutL homolog 1 (MLH1)-deficient and 35.8% (24/67) of EBV-positive GCs, compared with only 9.6% (82/864) of the MLH1-proficient and EBV-negative group (p<0.001). The loss of ARID1A expression was associated only with MLH1 deficiency and EBV positivity. On survival analysis, the loss of ARID1A expression was associated with worse prognosis only in MLH1-proficient and EBV-negative GC. Multivariate analysis revealed that both loss of ARID1A and decreased ARID1A expression were independent worse prognostic factors in patients with advanced GC. Conclusions Only in MLH1-proficient and EBV-negative GC, the loss of ARID1A expression is related to poorer prognosis.

BACKGROUND: Adenocarcinoma arising in the body or tail of the pancreas tends to be metastasized at the time of diagnosis, is mostly in inoperable stage, and poor in prognosis. In this study, we evaluated the adenocarcinoma arising in the body or tail of the pancreas and investigated the prognostic factors and ideal treatment. MATERIAL AND METHODS: We retrospectively analyzed 33 patients who were cytologically or histologically confirmed as adenocarcinoma in the body or tail of the pancreas at Samsung Medical Center from October 1994 to December 1999. RESULTS: The mean age of the patients in the resectable and unresectable groups were 63.4 and 60.6 year-old, respectively. The mean CA19-9 level was higher in unresectable group (5166.2u/ml), compared to the resectable group (964.7u/ml).(p=0.039) In the resectable group, the body was the most common location of the tumor, and in the unresectable patient group, the tail was more prevalent.(p= 0.021) The mean survival time of the resectable group was 15.1months. The univariate analysis of the resectale group showed that the age, sex, lymph node metastasis, chemotheraeutic modalities, radiotherapeutic modalities, and the location of tumor were not significantly related with the prognosis. In unresetable group, the mean survival time was 6.4months. The mean survival time were 3.3 months in patients over 60 year-old and 9.9 months in patients less than 60, showing statistically significant difference.( p=0.007) The mean survival time were 12.2 months and 3.4 months in patients who received the chemotherapy and who did not, respetively.(p=0.004) Evaluating the relationship between the extent of metastasis and survival, the mean survival length of single metastasis was 9.3 months, showing significantly higher survival length compared that of multiple metastasis.(p=0.027) Patient's sex, radiotherapeutic modality and location of the tumor were not significantly related with the prognosis. Multivariate analysis of prognostic factor showed that the patietnt's age (p=0,842), the extent of metastasis( p=0.458), and chemotherapeutic modality (p=0.078) were unrelated with prognosis. CONCLUSION: In adenocarcinoma arising in the body and tail of the pancreas, the CA19-9 level and tumor location could be utilized as indicating factors of the operability of the tumor. Age, sex, lymph node metastasis, and location of the adenocarcinoma are not significantly related with the survival length in both the resectable and unresectable groups. Also, in both groups, the chemotherapeutic and radiotherapeutic modalities were not related with the survival length.

PURPOSE: Adequate health-related information provided by health professionals may help cancer patients overcome their uncertain situation and manage their healthcare. To provide information effectively, there is a need to understand the content of the patients' essential information. The purpose of this study was to identify recent informational needs of postoperative gastric cancer patients. MATERIALS AND METHODS: Data were collected from 190 postoperative gastric cancer patients who attended the Stomach Cancer Patients' Day ceremony (18 November 2008) held by the Stomach Cancer Center of Samsung Medical Center with the use of a questionnaire which measured informational needs. A questionnaire with 37 items was comprised of domains of diagnostic tests, cancer therapy, prognosis, follow-up, sexual activity, stomach cancer-related information, and 7 single items. RESULTS: The priorities of informational needs were the domains of prognosis, ways of healthcare during treatment (a single item), follow-up, stomach cancer-related information, cancer therapy, and diagnostic tests (in descending order). Items related to prognosis, diet, and management of their healthcare ranked in the top 10 informational need scores. As age decreased, the degree of informational needs about diagnostic tests, cancer therapy, sexual activity, and stomach cancer-related information increased. CONCLUSION: We suggest that prognosis-related information based on the accumulated institutional therapeutic outcomes and objective prognosis data should be incorporated in the current education program. Health professionals should provide comprehensible information content to cancer patients and caregivers and encourage patients to participate in their therapy with a more positive attitude.

The incidence of heterotopic gastric mucosa located in the submucosa in resected stomach specimens has been reported to be 3.0 to 20.1%. Heterotopic gastric mucosa is thought to be a benign disease, which rarely becomes malignant. Heterotopic gastric mucosa exists in the gastric submucosa, and gastric cancer rarely occurs in heterotopic gastric mucosa. Since tumors are located in the normal submucosa, they appear as submucosal tumors during endoscopy, and are diagnosed through endoscopic biopsies with some difficulty. For such reasons, heterotopic gastric mucosa is mistaken as gastric submucosal tumor. Recently, two cases of early gastric cancer arising from heterotopic gastric mucosa in the gastric submucosa were treated. Both cases were diagnosed as submucosal tumors based on upper gastrointestinal endoscopy, endoscopic ultrasound, and computed tomography findings, and in both cases, laparoscopic wedge resections were performed, the surgical findings of which also suggested submucosal tumors. However, pathologic assessment of the surgical specimens led to the diagnosis of well-differentiated intramucosal adenocarcinoma arising from heterotopic gastric mucosa in the gastric submucosa.

PURPOSE: In spite of a very poor prognosis for primary gastric cancer invading neighboring organs, combined resection of the involved adjacent organ may improve. Whether pancreaticoduodenectomy in advanced distal gastric cancer improves the survival is controversial. We conducted this study to evaluate the results of pancreaticoduodenectomy in advanced distal gastric cancer. METHODS: We retrospectively analysed 29 patients who underwent surgery at the Department of Surgery, Yonsei University College of Medicine, between January 1994 and December 2001. Patients included in this study had locally advanced distal gastric cancer, without evidence of distant metastases, which had invaded to the duodenum and/or pancreas head, or conglomerated infrapyloric lymph nodes. Patients were divided into two groups: pancreaticoduodenectomy (PD) (n=12), or palliative subtotal gastrectomy (PSTG) (n=17). We compared the clinicopathologic features, operative outcomes, recurrence and survival between these two groups. RESULTS: There were no differences in clinicopathologic features between the two groups. Operation time, incidence and amount of perioperative transfusion, postoperative hospital stay and morbidity were greater in the PD group than in the PSTG group. However, there was no postoperative mortality in either group. Five patients had systemic recurrence (liver, lung, and paraaortic LN metastases) in the PD group, while most patients experienced regional disease progression in the PSTG group. The survival of the PD group was significantly better than that of the PSTG group (P=0.0006). CONCLUSION: Pancreaticoduodenectomy can be safely performed and improves the prognosis for patients with locally far advanced distal gastric cancer that is associated with invasion into the duodenum and/or pancreas head, or conglomerated infrapyloric lymph nodes.

In situ follicular lymphoma is a newly defined entity among the lymphoid neoplasms and is defined as architecturally normal-appearing lymph nodes and other lymphoid tissues that have one or more follicles that demonstrate bcl-2 overexpressing centrocytes and centroblasts, with or without a monomorphic cytologic appearance suggestive of follicular lymphoma. Here we present a case of in situ follicular lymphoma diagnosed during the follow-up after a complete response to the treatment of lymphocyte-rich classical Hodgkin's lymphoma. In our case, because only a few germinal centers contained bcl-2 overexpressing cells, we missed the diagnosis of in situ follicular lymphoma in the initial histological examination. We could establish the diagnosis only after performing bcl-2 immunostaining in the sequential biopsy. Therefore, we recommend that careful histological examination along with bcl-2 immunostaining is needed in patients with suspicious clinical findings.

Historically, digital rectal examination (DRE) had been the only method available to evaluate the prostate gland for malignant tumor. Recently, serum prostate specific antigen (PSA), transrectal ultrasonography (TRUS) and magnetic resonance imaging (MRI) using endorectal coil have been added to the methods used to detect prostate cancer. But the roles of these tests in detecting cancer are currently undefined. Because of its low specificity, some reports have suggested the routine use of TRUS be discouraged. The present study was undertaken to evaluate the value of TRUS in the detection of prostate cancer. In a retrospective study, 123 BPH patients were examined by TRUS and PSA measurement. All patients were planned for prostatectomy and they had no evidence for prostate cancer at DRE. Of 123 patients with pathologically proven diagnosis, 10 patients had prostate cancer and 113 patients had BPH. Among the patients with prostate cancer, 6 patients had elevated PSA level ( >10ng/mL), while a patient had normal PSA level. Of 66 patients whose PSA levels were between 4 and 10ng/mL, only 3 patients had prostate cancer. Among 10 patients with prostate cancer, one patient had positive finding in TRUS, while 9 patients had negative finding. Among 113 patients with BPH, 17 patients had positive findings in TRUS and 96 patients had negative findings. Over all TRUS sensitivity and specificity for prostate cancer detection was 10% and 84.9% respectively. From our data we conclude; 1. The use of TRUS in BPH patients with negative DRE and PSA less than 10ng/mL seems to be questionable. 2. For the patients with negative DRE and PSA higher than 10ng/mL, sono-guided biopsy should be done regardless of the result of TRUS.
