Primary duodenal adenocarcinoma is a rare malignant neoplasm accounting for 0.3% of all gastrointestinal tract carcinomas. We herein present one case of duodenal adenocarcinoma after duodenal neuroendocrine carcinoma. Poorly differentiated duodenal neuroendocrine carcinoma with liver metastasis (TxNxM1) was confirmed, and eight cycles of palliative chemotherapy (5-fluorouracil/etoposide/cisplatin) were administered. The patient was then in a clinically complete response status. About 1 year later, newly developed adenocarcinoma was detected at the same site. It was completely surgically resected, and the patient was cured.

The paraneoplastic nephrotic syndrome can be diagnosed by clinical and immunologic features. We have had a case of paraneoplastic nephrotic syndrome in the patients with aadeno-carcinoma of the lung, whose diagnosis was made by excluding other causes of nephrotic syndrome. The type of renal lesion was membranous glomerulopathy which commonly occurs in carcinoma. The quantity of proteinuria in this patient had decreased according to the improvement of lung cancer with combination chemotherapy. After fourth chemotherapy he was refractory to treatment, and unfortunately he had passed away with cardiac tamponade.

Double primary cancer means that more than two cancers with different origin exist independently in an individual. The diagnosis of double primary cancer was determined by following criteria. Each of the tumors must present a definite picture of malignancy, and each must be distinct, and the probability of one being a metastasis of the other must be excluded. Small cell carcinoma has a distinct biological behavior such as, early invasion and metastasis, a rapid clinical course, and significant sensitivity to chemotherapy. Small cell carcinoma in the esophagus is relatively rare, and rarer when it is combined with other malignant disease. We have experienced a case of double primary cancer, a 70-year-old man with esophageal small cell carcinoma and gastric adenocarcinoma, which were diagnosed by gastrointestinal endoscopic biopsy. A review of the Korean medical literature failed to reveal any previously described case of esophageal small cell carcinoma with gastric adenocareinoma. We report this case with review of literatures.

Trophoblastic differentiation in gynecologic nontrophoblastic tumor is very rare. Here we present a 66-year-old female with poorly differentiated endometrial carcinoma showing trophoblast-like differentiation. This tumor was in advanced stage with metastases to lung, liver, and bone at diagnosis. The multinucleated, syncytiotrophoblast-like cells were positive for beta-human chorionic gonadotropin (beta-hCG) by immunochemical stain. The level of beta-hCG was also elevated (219 mIU/ml) in the patient's serum, but dropped after surgery and chemotherapy. beta-hCG may be used as tumor marker in this case.

Pancreatic adenocarcinoma is a common disease that is rarely cured. Surgical resection remains the only treatment modality that has a curative potential, although the majority of patients are unsuitable for resection at the time of diagnosis. Chemoradiation therapy prior to a pancreaticoduodenectomy ensures that a patient who undergoes a complete resection multimodality therapy, avoids a resection in patients who have a rapidly progressive disease, and allows radiation therapy to be given to well oxygenated cells before, surgical devasculation. This permits the chance of resection of an unresectable pancreatic cancer by downstaging. A patient with cytologic proof of localized adenocarcinoma of the pancreatic head received an intravenously chemoradiation (Taxol, 50 mg/m2 intravenously for 3 hours week on 5 cycles, of Gemcytabine 1000 mg/m2/day intravenously for 3 days week on 2 cycles, of 4500 cGy) with the intention of proceeding to a resection operation, restaging was performed by computed tomography, magnetic resonance imaging from 5 weeks every months due to ongoing decreasing of tumor size after the chemoradiation. At laparotomy, the patient didn't have suspected metastatic disease, the tumor size was 2 x 3 cm on the pancreas head and was infiltrating into the portal vein for about 3 cm length on right side. A pancreaticoduodenectomy along with a portal vein and superior mesenteric vein resection was done and then reconstruction of a vascular anastomosis by using the right side of the internal jugular vein. Perioperative complications didn't occur. In conclusion, preoperative chemoradiation of a localized advanced pancreatic tumor has no added risk to the operative complications and the prospects for resectability are enhanced.

BACKGROUND: The incidence of adenocarcinoma of the lung has been increasing worldwide, and it has been generally been accepted to be relatively unrelated to smoking with a female preponderance. The aim of this study was to examine the gender-related pathological and survival differences in patients with an adenocarcinoma of the lung. MATERIAL AND METHOD: A retrospective review of the clinical information of patients diagnosed with an adenocarcinoma of the lung at Kosin Medical Center from January 1999 to September 2005 was performed. The patient's demographics (age, gender), smoking history, stage, serum tumor marker, pathology classification, EGFR mutation, K-ras mutation, treatment methods, and survival time were analyzed. RESULT: Of the 438 patients, 179 (40.9%) were female. The median age at the diagnosis was 58 years for females and 59 years for males. However, 25.8% of women and only 17.7% of men were under 50 years of age (p=0.02). The distribution of the disease stage was similar in both men and women. The bronchioloalveolar carcinoma component was diagnosed more often in women (11.2%) than in men (5.0%). The overall survival rate was higher in women than in men (p=0.01), and women had a superior therapeutic response to a combined treatment of surgery and chemotherapy. CONCLUSION: This study showed significant genders differences in terms of the smoking history, bronchioloalveolar carcinoma component, overall survival, and survival after combined treatment of surgery and chemotherapy. Therefore, gender differences should be considered when diagnosing and treating adenocarcinomas of the lung.

Thirty-five patients with locally advanced gastric carcinoma were treated with combined modalities of external radiation therapy (RT) and 5-FU based chemotherapy at the Division of Radiation Therapy, Department of Radiology, Kangnam St, Mary's Hospital, Catholic University Medical College from May 1983 to May 1987. The purpose of this retrospective study is for the evaluation of the palliative response to RT. There were 25 men and 10 women. The age ranged from 38 to 80 years (median: 56 years). The pathologic classification showed 14 (40%) poorly differentiated, 12(34%) moderately differentiated, 3 (9%) well differentiated adenocarcinomas, 2 mucinous cystadenocarcinomas, 1 signet ring cell and 3 not specified ones. The time intervals from the initial surgicopathologic diagnosis to the starting day of RT was within 1 year for 18 (51%), 1 to 2 years for 8 (23%) and 2 to 3 years for 5 (14%), respectively. The major symptoms to be treated were pain in 30 (86%), mass for 29 (83%), obstruction for 11 (31%) and jaundice for 9 (26%) patients. The response rate (patient number of positive response/total patient number) according to treated radiation doses were observed as follows; 14/16(88%) for 40~50 gy, 8/10 (80%) for over 50 gy, 6/8 (75%) for 30~40 gy and 8/15 (53%) for 20~30 gy in decreasing order. The over all survival was 3.6 months and that of 5FU+RT, FAM+RT and RT alone groups were 4.6 months, 3.7 months and 2.5 months respectively. Complications induced by RT were nausea and vomiting in 16 (46%), diarrhea in 7 (20%), leukopenia in 6 (17%) and anemia and intercurrent pneumonia in each 3 (9%) patients in decreasing order.

PURPOSE: For malignant diseases, predictions about tumor behavior and determination of appropriate therapy are based on the primary tumor sites, but 2-9% of cancer patients are diagnosed without identifiable primary tumor sites. Metastatic tumors of unknown primary origin (MUO) are a heterogeneous group of tumors with variable natural histories. The majority of these patients fall outside of treatable subjects and seldom respond to therapy. To define further the natural history of MUO and identify prognostic factors, we undertook a clinical analysis of 141 consecutive patients with a presumed diagnosis of MUO. MATERIALS AND METHODS: One hundred forty-one patients were diagnosed with unknown primary tumor from Jan. 1, 1992 through Aug. 31, 1995. The primary end point for the study was survival, which was calculated from the first day of patient registration diagnosed histologically. The survival curves were estimated using the Kaplan-Meier method and compared using the log-rank test. To identify important prognostic factors, univariate and multivariate analyses were conducted. RESULTS: Most of the 141 patients had histologic or cytologic evidence of adenocarcinoma and had more than one site metastatically involved. The predominant sites of tumor involvement were lymph node, peritoneum, bone, liver, lung, and pleura. Univariate and multivariate analyses identified numerous important prognostic factors with a significant influence on survival, including performance status (P 0.0001), specific organ sites involved (lung P 0.0076 or liver P 0.0310), and chemotherapy group (P- 0.0480). CONCLUSION: This study validated clinical courses and important prognostic factors that had an impact on survival in MUO.

Despite improvements in the surgical treatment of gastric adenocarcinomas, the recurrence rates remain high in patients with advanced-stage disease. Most of the recurrence occurs within 3 years of the surgical resection, and nearly 90% of the patients with recurrence die within 2 years of the diagnosis of recurrence. A recent study analyzed recurrence patterns for patients who had undergone a potentially curative gastrectomy. For those patients, 33% of the recurrences involved locoregional sites, 44% the peritoneum, and 38% distant sites. A 51-year-old female patient was diagnosed with stomach cancer and underwent a total gastrectomy with D2 lymph node dissection during Oct. 1999. The pathologic report indicated a T3N1M0 tumor. We performed immunochemotherapy for 2 years with regular follow up. A gastrofiberscopic examination done during Sep. 2004, cancer recurrence was found at the *Kim's tie site of the jejunual loop. We did an abdominal exploration and a segmental resection of cancer site with pathologically negative resection margins. After the operation, we started secondary chemotherapy with TS-1.

The purpose of this study is to report a rare case of mandibular adenocarcinoma that was diagnosed due to metastasis from the prostate. Numb chin syndrome (NCS), which was associated with this case, is also discussed. Computed tomography (CT) and an intraoral incisional biopsy of the left mandibular area were performed. Urology consultation, hormone therapy, chemotherapy and follow-up radiographic images were administered. Histological examination of the incised specimen revealed moderately differentiated adenocarcinoma. The Gleason score was 8 (primary 4/secondary 4). Immunohistochemical features and radiographic results confirmed the diagnosis of metastasis from prostate adenocarcinoma, moderately differentiated. The patient's prostate-specific antigen (PSA) level was very high. After hormone treatment, the patient's PSA levels dropped gradually. Seventeen months later, in May 2015, the PSA level was elevated. The 18-month follow-up CT image indicated that the patient's condition was aggravated. Docetaxel chemotherapy was started in June 2015 (18 months later), and the sixth cycle of the therapy is in progress. Oral metastases that originate from prostate adenocarcinoma are rare and can induce various periosteal reactions. Hormone therapy, chemotherapy and close follow-up could be additional, appropriate treatment, and were applied in this case. Finally, NCS is a valuable indicator of metastatic disease in the mandible.
