ABSTRACT

Purpose@#The treatment of male breast cancer (MBC) has been extrapolated from female breast cancer (FBC) because of its rarity despite their different clinicopathologic characteristics. We aimed to investigate the distribution of intrinsic subtypes based on immunohistochemistry, their clinical impact, and treatment pattern in clinical practice through a multicenter study in Korea. @*Materials and Methods@#We retrospectively analyzed clinical data of 248 MBC patients from 18 institutions across the country from January 1995 to July 2016. @*Results@#The median age of MBC patients was 63 years (range, 25 to 102 years). Among 148 intrinsic subtype classified patients, 61 (41.2%), 44 (29.7%), 29 (19.5%), and 14 (9.5%) were luminal A, luminal B, human epidermal growth factor receptor 2, and triple-negative breast cancer, respectively. Luminal A subtype showed trends for superior survival compared to other subtypes. Most hormone receptor-positive patients (166 patients, 82.6%) received adjuvant endocrine treatment. Five-year completion of adjuvant endocrine treatment was associated with superior disease-free survival (DFS) in patients classified with an intrinsic subtype (hazard ratio [HR], 0.15; 95% confidence interval [CI], 0.04 to 0.49; p=0.002) and in all patients (HR, 0.16; 95% CI, 0.05 to 0.54; p=0.003). @*Conclusion@#Distribution of subtypes of MBC was similar to FBC and luminal type A was most common. Overall survival tended to be improved for luminal A subtype, although there was no statistical significance. Completion of adjuvant endocrine treatment was associated with prolonged DFS in intrinsic subtype classified patients. MBC patients tended to receive less treatment. MBC patients should receive standard treatment according to guidelines as FBC patients.

ABSTRACT

Cancer of unknown primary (CUP) is a heterogenous group of cancers for which the anatomical site of origin is unidentifiable on the basis of standard evaluation and imaging. CUPs account for 2-5% of all malignancies and are characterized by early metastatic dissemination, aggressive clinical course, and poor response to palliative chemotherapy. It is important to identify favorable-risk CUP patients (10-20%), as they harbor chemo-sensitive and potentially curable tumors, and may require long-term disease control. Empirical combination chemotherapy has traditionally been the standard first-line therapy for most patients (80-90%), who do not belong to favorable-risk subsets; however, this approach has only modest benefits, with a median overall survival of < 1 year. Evidence supporting the clinical use of molecular tissue of origin (TOO) tests is still lacking. Two recent randomized clinical trials failed to show the benefit of TOO-based site-specific therapy over empirical chemotherapy. In an era of precision medicine, the use of comprehensive molecular profiling will provide opportunities to identify patient subsets who are susceptible to targeted therapies and immunotherapies.

ABSTRACT

BACKGROUND/AIMS: Colorectal cancer is associated with different anatomical, biological, and clinical characteristics. We determined the impact of the primary tumor location in patients with metastatic colorectal cancer (mCRC). METHODS: Demographic data and clinical information were collected from 1,115 patients from the Republic of Korea, who presented with mCRC between January 2009 and December 2011, using web-based electronic case report forms. Associations between the primary tumor location and the patient's clinical characteristics were assessed, and factors inf luencing overall survival were analyzed using Cox proportional hazards regression models. RESULTS: Of the 1,115 patients recruited to the study, 244 (21.9%) had right colon cancer, 483 (43.3%) had left colon cancer, and 388 (34.8%) had rectal cancer. Liver and lung metastases occurred more frequently in patients with left colon and rectal cancer (p = 0.005 and p = 0.006, respectively), while peritoneal and ovarian metastases occurred more frequently in patients with right and left colon cancer (p < 0.001 and p = 0.031, respectively). The median overall survival of patients with tumors originating in the right colon was significantly shorter than that of patients whose tumors had originated in the left colon or rectum (13.7 months [95% confidence interval (CI), 12.0 to 15.5] vs. 18.0 months [95% CI, 16.3 to 19.7] or 19.9 months [95% CI, 18.5 to 21.3], respectively; p = 0.003). Tumor resection, the number of metastatic sites, and primary tumor location correlated with overall survival in the univariate and multivariate analyses. CONCLUSIONS: Primary tumor location influences the metastatic sites and prognosis of patients with mCRC.

ABSTRACT

PURPOSE: Although chemotherapy is recommended by various guidelines for advanced biliary tract cancer (BTC), the evidence supporting its use over best supportive care (BSC) is limited. The aim of this study was to investigate the survival benefit of chemotherapy over that of BSC in advanced BTC patients. MATERIALS AND METHODS: Advanced BTC patientswith a good performance status (Eastern CooperativeOncologyGroup [ECOG] 0-2) were eligible for the study. Data were retrospectively collected from four tertiary cancer centers and analyzed using propensity score matching (PSM). Of the 604 patients enrolled, 206 received BSC and 398 received chemotherapy. PSM analysis was performed using the following variables: age, ECOG status, carcinoembryonic antigen (CEA) level, white blood cell level, albumin level, total bilirubin level, and aspartate aminotransferase level. The sample size of each group was 164 patients after PSM. Median survival was compared between the two groups by using the Kaplan-Meier method, and prognostic factors were investigated using Cox proportional regression analysis. RESULTS: In post-PSM analysis, the respective median survival for the chemotherapy and BSC groups was dependent on the following prognostic factors: total population, 12.0 months vs. 7.5 months (p=0.001); locally advanced disease, 16.7 months vs. 13.4 months (p=0.490); cancer antigen 19-9 ≤ 100 IU/mL, 12.7 months vs. 10.6 months (p=0.330); and CEA ≤ 3.4 ng/mL, 17.1 months vs. 10.6 months (p=0.052). CONCLUSION: Chemotherapy improved overall survival of patients with advanced BTC who had a good performance status. However, this survival benefit was not observed in BTC patients with locally advanced disease or with lower tumor marker. Individualized approach is needed for initiation of palliative chemotherapy in advanced BTC.

ABSTRACT

BACKGROUND/AIMS: Because of rarity, role of chemotherapy of bladder adenocarcinoma are still unidentified. Therefore, we performed a retrospective analysis of the clinical features and chemotherapy outcomes of bladder adenocarcinoma. METHODS: Eligible patients for this retrospective analysis were initially diagnosed with bladder adenocarcinoma and presented with a clinically no other primary site of origin. The collected data included age, gender, performance status, stage, hemoglobin, albumin, initial date of diagnosis, treatment modality utilized, response to treatment, presence of relapse, last status of patient, and last date of follow-up. RESULTS: We retrospectively reviewed 29 patients, who were treated with chemotherapy for bladder adenocarcinoma at 10 Korean medical institutions from 2004 to 2014. The median age of patients was 58 years (range, 17 to 78) and 51.7% of the patients were female. Urachal adenocarcinoma was identified in 15 patients. Of 27 symptomatic patients, 22 experienced gross hematuria. Twelve patients were treated with 5-f luorouracil based chemotherapy, five were gemcitabine based, three were taxane and others. Thirteen of them achieved complete response (10.3%) or partial response (34.5%). Median progression-free survival (PFS) and overall survival (OS) for all patients were 10.6 months (95% confidence interval [CI], 9.5 to 11.6) and 24.5 months (95% CI, 1.2 to 47.8), respectively. The cases of urachal adenocarcinoma exhibited worse tendency in PFS and OS (p = 0.024 and p = 0.046, respectively). CONCLUSIONS: Even though bladder adenocarcinoma had been observed moderate effectiveness to chemotherapy, bladder adenocarcinoma is a highly aggressive form of bladder cancer. PFS and OS were short especially in urachal carcinoma.

ABSTRACT

PURPOSE: While the Trastuzumab for Gastric Cancer (ToGA) trial demonstrated the efficacy and safety of trastuzumab-based chemotherapy in HER2-positive metastatic gastric cancer, the overall survival (OS) benefit was not found in Asian and diffuse-type cancer patients. The aim of the study is to investigate predictive markers for trastuzumab-based chemotherapy. MATERIALS AND METHODS: Data of patients with HER2-positive gastric cancer treated with trastuzumab-based chemotherapy were analyzed retrospectively. RESULTS: A total of 168 Asian patients were included. The median age was 60 years (range, 27 to 85 years) and the male:female ratio was 118 (70.2%):50 (29.8%). Fourteen (8.3%), 63 (37.5%), 75 (44.6%), and 11 (6.5%) patients had well, moderately, poorly-differentiated tubular adenocarcinoma and signet ring cell carcinoma, respectively. With 14 complete responses and 73 partial responses, the response rate was 50.6%. The median progression-free survival (PFS) was 10.2 months (95% confidence interval [CI], 8.7 to 11.7), and the median OS was 18.5 months (95% CI, 16.4 to 50.6). Next, we investigated the effect of poorly-differentiated histology (PDH, poorly-differentiated tubular adenocarcinoma+signet ring cell carcinoma) on clinical outcomes. The median PFS (8.9 months vs. 11.5 months, p=0.16) was slightly inferior in PDH patients, and the median OS was significantly shorter in PDH patients (14.6 months vs. 19.0 months, p=0.025). CONCLUSION: While subset analysis of the ToGA trial demonstrated that trastuzumab-based chemotherapy may not be beneficial for Asians and patients with PDH, our data may suggest that even in Asian patients and patients with PDH, trastuzumab-based chemotherapy could be associated with improved clinical outcomes in patients with HER2-positive gastric cancer.

ABSTRACT

The World Health Organization (WHO) defines a perivascular epithelioid cell tumor (PEComa) as a mesenchymal neoplasia composed of perivascular epithelioid cells with characteristic morphological and immunohistochemical features. They are rarely malignant. Indeed, only a few cases have been reported in the English literature, and this is the first case of PEComa reported in Korea. A 64-year-old man presented with an abdominal mass and peritoneal seeding. The patient underwent mass excision with descending colon resection and anastomosis. The primary mass and peritoneal seeding was diagnosed as a PEComa histopathologically. Seven months later, he developed liver metastasis and aggravated peritoneal seeding. Here, we report a case of malignant PEComa of the omentum.

ABSTRACT

Ulcerative colitis (UC) is a chronic idiopathic inflammatory disorder of the colon with a variable clinical course of exacerbation and remission. Extraintestinal manifestations of UC, including hematological disorders, such as the rare immune thrombocytopenic purpura (ITP), may be the presenting symptoms. We encountered the case of a 23-year-old man with UC who showed typical symptoms and endoscopic findings. Despite receiving steroid treatment, the patient developed severe thrombocytopenia. He was diagnosed with ITP, characterized by autoimmunity, a demonstrated low platelet count, normal bone marrow, positivity for autoantibody to platelet membrane antigen, and no splenomegaly. We initiated high dose intravenous immunoglobulin immediately for treatment of his steroid-refractory thrombocytopenia. The patient's hematochezia and platelet count improved following immunoglobulin treatment. After discharge, the patient's platelet count was maintained at a stable level and his condition was good. This case suggests that immunoglobulin therapy may be useful for treatment of ITP in UC.

ABSTRACT

Tuberculous peritonitis is one of the most common extrapulmonary tuberculosis. The presenting signs and symptoms, together with the carbohydrate antigen (CA) 125 status and imaging findings may resemble the primary peritoneal carcinoma or ovarian carcinoma. We herein report a case on a 71-year-old woman who is presented with abdominal distension, abdominal pain, nausea, anorexia. Abdomino-pelvic computed tomography scans reveal large amounts of ascites and mottled omentum with diffuse nodular masses, and the serum CA 125 level is elevated. The initial clinical diagnosis is the primary peritoneal carcinoma, but the final histological diagnosis confirms the tuberculous peritonitis. Thus, we discuss the differential diagnosis of tuberculous peritonitis from primary peritoneal carcinoma and also the problems especially found in old aged patients. In conclusion, although the elderly patients are suspected with malignancy, we should keep in mind the possibility of curable diseases and perform laparoscopic biopsy during the early stage aggressively.

ABSTRACT

The stomach is the most common site of gastrointestinal tract lymphoma, while synchronous mucosa-associated lymphoid tissue (MALT) lymphomas of the stomach and duodenum are very rare. A literature review found no reported case of synchronous gastroduodenal MALT lymphomas with involvement of the bone marrow and spleen. Here, we describe the case of a 62-year-old male who was diagnosed with synchronous MALT lymphomas of the stomach and duodenum based on upper gastrointestinal endoscopy and pathology. Other staging evaluations, including colonoscopy, abdominopelvic and chest computed tomography (CT), 18F fludeoxyglucose-positron emission tomography (FDG-PET), and a bone marrow examination, showed involvement of the bone marrow and spleen. We diagnosed stage EIV MALT lymphoma and began systemic chemotherapy. We report the first case of MALT lymphomas arising synchronously in both the stomach and duodenum with bone marrow involvement and review the literature.

ABSTRACT

Common variable immunodeficiency (CVID) is the most common symptomatic primary antibody deficiency syndrome and has a high prevalence of gastrointestinal complications. We report the case of a 36-year-old male with CVID who presented with chronic intractable diarrhea and malabsorption. A comprehensive evaluation revealed no secondary causes of his symptoms. He was treated symptomatically without improvement. After receiving systemic steroid treatment, his symptoms improved, but returned soon after tapering the steroid. When he was subsequently administered oral budesonide, his symptoms and quality of life improved; this effect lasted for 20 months without unacceptable side effects.

ABSTRACT

PURPOSE: Little is known about the clinical features of advanced gastric cancer (AGC) combined with disseminated intravascular coagulation (DIC). The main objective of this study was to determine the clinical outcome of patients with AGC complicated by DIC. MATERIALS AND METHODS: We conducted a retrospective review of 68 AGC patients diagnosed with DIC at four tertiary medical centers between January 1995 and June 2010. RESULTS: Sixty eight patients were included. The median age was 55 years (range, 25 to 78 years). Nineteen patients received chemotherapy, whereas 49 patients received only best supportive care (BSC). The median overall survival (OS) of the 68 patients was 16 days (95% confidence interval [CI], 11 to 21 days). Significantly prolonged OS was observed in the chemotherapy group, with a median survival of 61 days compared to 9 days in the BSC group (p or =65 vs. <65; hazard ratio [HR], 0.38; 95% CI, 0.18 to 0.78; p<0.001), chemotherapy (BSC vs. chemotherapy; HR 0.31; 95% CI, 0.15 to 0.63; p<0.001), and previous chemotherapy (yes or no; HR, 0.49; 95% CI, 0.25 to 0.98; p<0.045) were consistently independent prognostic factors that impacted OS. CONCLUSION: Our study showed that patients with AGC complicated by DIC had very poor OS, and suggested that chemotherapy might improve OS of these patients.

ABSTRACT

Skin metastasis from internal carcinoma rarely occurs and it has an incidence of 0.7% to 9%. Although the prognosis of the skin metastases varies considerably depending on the type of the primary malignancy, presence of metastatic skin cancer usually implies a widespread systemic disease and a high mortality. A 50-year-old Korean male patient visited Dankook University Hospital for evaluation of skin rash on his whole abdomen of about 1 month's duration. He had undergone laparoscopy-assisted distal gastrectomy due to early gastric cancer about 3 months ago. He did not complain of any noticeable symptoms like febrile sense or pruritus. Skin biopsy was performed on the periumbilical area at previous port site and around the scar. Microscopic examination revealed multiple malignant cells in lymphatic spaces, consistent with metastatic carcinoma. He was therefore diagnosed with isolated skin metastasis from early gastic cancer. Because of patient's poor liver function, systemic chemotherapy could not be performed and only best supportive care was provided. Herein, we report a rare case of cellulitis-like skin metastasis from early gastric cancer with a brief review of the literature.

ABSTRACT

Hepatitis C virus (HCV) is one of the main viral causes of hepatocellular carcinoma (HCC) and is associated with lymphoproliferative disorder such as non-Hodgkin's lymphoma (NHL). However, there are only few case reports on concomitantly induced NHL and HCC by HCV. Herein, we report a case of synchronous NHL and HCC in a patient with chronic hepatitis C which was unexpectedly diagnosed during liver transplantation surgery. This case suggests that although intrahepatic lymph node enlargements are often considered as reactive or metastatic lymphadenopathy in chronic hepatitis C patients with HCC, NHL should also be considered as a differential diagnosis.

ABSTRACT

BACKGROUND/AIMS: In Asia, the incidence of non-Hodgkin lymphoma (NHL) has increased in recent decades. Waldeyer's ring (WR) is the most common site of NHL involving the head and neck. In this study, the pathological distribution of WR-NHL and its clinical features were analyzed retrospectively. METHODS: From January 2000 through December 2010, we analyzed the medical records of 328 patients from nine Korean institutions who were diagnosed with WR-NHL. RESULTS: The study group comprised 197 male and 131 female patients with a median age of 58 years (range, 14 to 89). The rate of localized disease (stage I/II) was 64.9%, and that of low-risk disease (low/low-intermediate, as defined by the International Prognostic Index) was 76.8%. Diffuse large B-cell lymphoma (DLBCL; 240 patients, 73.2%) was the most common pathologic subtype, followed by peripheral T-cell lymphoma (14 patients, 4.3%) and nasal NK/T-cell lymphoma (14 patients, 4.3%). WR-NHL occurred most frequently in the tonsils (199 patients, 60.6%). Extranodal involvement was greater with the T-cell subtype (20 patients, 42.5%) compared with the B-cell subtype (69 patients, 24.5%). Multivariate analyses showed that age > or = 62 years, T-cell subtype, and failure to achieve complete remission were significant risk factors for overall survival. CONCLUSIONS: DLBCL was found to have a higher incidence in Korea than those incidences reported by other WR-NHL studies. T-cell lymphoma occurred more frequently than did follicular lymphoma. T-cell subtype, age > or = 62 years, and complete remission failure after first-line treatment were significant poor prognostic factors for overall survival according to the multivariate analysis.

ABSTRACT

We report here a case of oral myiasis in the Republic of Korea. The patient was a 37-year-old man with a 30-year history of Becker's muscular dystrophy. He was intubated due to dyspnea 8 days prior to admission to an intensive care unit (ICU). A few hours after the ICU admission, 43 fly larvae were found during suction of the oral cavity. All maggots were identified as the third instars of Lucilia sericata (Diptera: Calliphoridae) by morphology. We discussed on the characteristics of myiasis acquired in Korea, including the infection risk and predisposing factors.

ABSTRACT

BACKGROUND: Brachial-ankle pulse wave velocity (baPWV) is known to be a good surrogate marker of clinical atherosclerosis. Atherosclerosis is a major predictor for developing neuropathy. The goal of this study was to determine the relationship between baPWV and diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes. METHODS: A retrospective cross-sectional study was conducted involving 692 patients with type 2 diabetes. The correlation between increased baPWV and DPN, neurological symptoms, and neurological assessment was analyzed. DPN was examined using the total symptom score (TSS), ankle reflexes, the vibration test, and the 10-g monofilament test. DPN was defined as TSS > or =2 and an abnormal neurological assessment. Data were expressed as means+/-standard deviation for normally distributed data and as median (interquartile range) for non-normally distributed data. Independent t-tests or chi-square tests were used to make comparisons between groups, and a multiple logistic regression test was used to evaluate independent predictors of DPN. The Mantel-Haenszel chi-square test was used to adjust for age. RESULTS: Patients with DPN had higher baPWV and systolic blood pressure, and were more likely to be older and female, when compared to the control group. According to univariate analysis of risk factors for DPN, the odds ratio of the baPWV > or =1,600 cm/sec was 1.611 (95% confidence interval [CI], 1.072 to 2.422; P=0.021) and the odds ratio in female was 1.816 (95% CI, 1.195 to 2.760; P=0.005). CONCLUSION: Increased baPWV was significantly correlated with peripheral neuropathy in patients with type 2 diabetes.

ABSTRACT

Multiple primary neoplasms, defined as the occurrence of multiple malignant neoplasms in the same individual, were first reported by Billroth in 1889. With gradual improvements in diagnostics, and the early detection and effective treatment of malignant neoplasms, the prevalence of multiple primary neoplasms seems to be increasing. Although there have been several reports of triple primary neoplasms in Korea, cases of quadruple neoplasms are rare. Recently, we diagnosed a 69-year-old male with primary neoplasms in the lung, esophagus, vocal cords, and hypopharynx. The authors report this rare case of four metachronous primary neoplasms and provide a review of the literature.
