We observed a rare case of invasive mucinous adenocarcinoma (IMA) with a lepidic-predominant pattern accompanied by pulmonary tuberculosis. An 85-year-old man with repeated cough and sputum was admitted to Xinhua Hospital. T-SPOT test result was 212 pg/ml (reference value of negative is < 14 pg/ml), Mycobacterium tuberculosis culture was positive, and tuberculin skin test (PPD) was negative (skin induration < 5 mm). The patient was treated with several courses of antibiotics and anti-tuberculosis treatments. Repeated chest CT scans showed disease progression. Bronchoscopy yielded negative results. PET-CT scans showed negative results. A percutaneous lung biopsy revealed mucin-secreting cells lining the alveolar walls. IMA with a lepidic-predominant pattern was diagnosed after invasiveness was found after experimental treatments. Simultaneous occurrence of pulmonary tuberculosis and lung cancer are common; however, the present case of IMA having a lepidic-predominant pattern and coexisting with active tuberculosis has not been reported yet.

OBJECTIVE: This is a retrospective study aimed at clarifying the details of recurrence patterns and sites in patients with cervical cancer treated with definitive radiation therapy (RT). METHODS: Data were analyzed from consecutive patients, admitted to the University of Tokyo Hospital (Tokyo, Japan) between 2001 and 2013, who had received definitive RT, with or without chemotherapy, for International Federation of Gynecology and Obstetrics stages IB-IVA cervical cancer. RESULTS: One hundred and thirty-seven patients formed the patient cohort. The median follow-up period for surviving patients was 57.0 months. A complete response was achieved in 121 patients (88%). Of these, 36 (30%) developed a cancer recurrence during follow-up. The first sites of recurrence were located in intra-RT fields in nine, outside RT fields in 20, and both in seven patients. In the intra-RT field group, all patients showed a local recurrence, while no one experienced an isolated pelvic lymph node (PLN) recurrence. In the outside RT field group, the most frequent site of recurrence was lung (60%), and three-quarters of patients were free from intra-RT field recurrence until the last follow-up. Of the entire cohort, including 48 PLN-positive patients, only seven patients (5.1%) developed PLN persistence or recurrence, all in the common iliac, internal iliac, and/or obturator nodes, and all with another synchronous relapse. CONCLUSION: Local disease was a major type of intra-RT field recurrence, while PLN control was favorable even in initially PLN-positive patients. The predominance of outside RT field recurrence alone highlights issues concerning distant control, including the intensity enhancement of systematic therapy.

OBJECTIVETo investigate the predictive value of P53, Ki-67, HER2 protein detection in neoadjuvant chemotherapy for adenocarcinoma of gastroesophageal junction (AGEJ).

METHODSPreoperative biopsy specimens and clinical data of 72 patients of locally advanced Siewert II AGEJ between June 2010 and December 2013 were reviewed. All the patients received SOX scheme neoadjuvant chemotherapy, and were divided into effective group (complete response plus partial response) and ineffective group (stable disease plus progressive disease). Expressions of above 3 proteins were detected by immunohistochemistry in all the patients before neoadjuvant chemotherapy. The relationship between various proteins and efficacy of chemotherapy was analyzed by univariate and logistic multivariate regression analyses.

RESULTSAll the 72 patients successfully completed 2 cycles of SOX neoadjuvant chemotherapy, among them, 5 cases (6.9%) with complete response, 30 cases (41.7%) with partial response, 31 cases (43.1%) with stable disease, 6 cases (8.3%) with progressive disease, including 35 cases in effective group and 37 cases in ineffective group. Compared with ineffective group, the positive expression rate of P53 was significantly reduced (25.0% vs. 45.9%, P=0.020), and that of Ki-67 significantly increased (77.1% vs. 43.2%, P=0.003), however, there was no significant difference in the expression rate of HER2 between the two groups (P>0.05). Multivariate analysis showed that Ki-67 was the independent predictive factor for the efficacy of neoadjuvant chemotherapy (P=0.015). Spearman rank correlation showed that Ki-67 expression was positively correlated with HER2 expression (r=0.259, P=0.028), but P53 expression was not correlated with Ki-67 or HER2 (r=0.140, 0.042, P=0.240, 0.725, respectively).

CONCLUSIONSSOX neoadjuvant chemotherapy is safe and effective for AGEJ, especially for patients with depressed expression of P53 and elevated expression of Ki-67, which both may be used as reference for the prediction of chemotherapy efficacy. There is no correlation between P53 and Ki67 proteins, so combined detection may improve the predictive value.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.

The patient was a 70-year-old male whose chief complaints were obstructive jaundice and weight loss. Abdominal imaging studies showed a 2.5 cm sized mass at the distal common bile duct, which was suggestive of bile duct cancer. Eccentric enhancing wall thickening in the transverse colon was also shown, suggesting concomitant colon cancer. A colonoscopy revealed a lumen-encircling ulcerofungating mass in the transverse colon, that was pathologically proven to be adenocarcinoma. The bile duct pathology was also adenocarcinoma. Pylorus-preserving pancreaticoduodenectomy and extended right hemicolectomy were performed under the diagnosis of double primary cancers. Postoperative histopathologic examination revealed moderately differentiated mucinous adenocarcinoma of transverse colon cancer, and mucinous adenocarcinoma of the distal common bile duct. Immunohistochemical staining studies showed that the bile duct cancer had metastasized from the colon cancer. The patient recovered uneventfully from surgery and will be undergoing chemotherapy for three months.

Primary colorectal choriocarcinoma is a rare neoplasm. Only 19 cases have been reported worldwide, most of which involved adenocarcinomas. The prognosis is usually poor, and the standard therapy for this tumor has not been established. A 61-year-old woman presented with constipation and lower abdominal discomfort. She was diagnosed with primary adenocarcinoma with focal choriocarcinomatous differentiation in the sigmoid colon and liver metastasis. Because the serum beta-human chorionic gonadotropin level was not significantly elevated, and because only focal choriocarcinomatous differentiation was diagnosed, we selected the chemotherapy regimen that is used for the treatment of metastatic colorectal adenocarcinoma. The patient survived for 13 months after the initial diagnosis. This is the first case in Korea to assess the suppressive effects of the standard chemotherapy for colorectal adenocarcinoma against coexisting colorectal choriocarcinoma and adenocarcinoma.

Strongyloides stercoralis can cause systemic infection, termed strongyloidiasis, and gastrointestinal ulcer disease in immunocompromised patients. However, to our knowledge, there are no reported cases of comorbid gastric adenocarcinoma and S. stercoralis infection. Here, we report a case of an 81-year-old Korean man who presented with S. stercoralis infection coexisting with early gastric adenocarcinoma (T1aN0M0). S. stercoralis eggs, rhabditiform larvae, and adult females were observed in normal gastric and duodenal crypts. They were also observed in atypical glands representative of adenocarcinoma and adenoma. Preliminary laboratory tests revealed mild neutrophilic and eosinophilic leukocytosis. A routine stool test failed to detect rhabditiform larvae in the patient's fecal sample; however, S. stercoralis was identified by PCR amplification and 18S rRNA sequencing using genomic DNA extracted from formalin-fixed paraffin-embedded tissues. Postoperatively, the patient had a persistent fever and was treated with albendazole for 7 days, which alleviated the fever. The patient was followed-up by monitoring and laboratory testing for 4 months postoperatively, and no abnormalities were observed thus far. The fact that S. stercoralis infection may be fatal in immunocompromised patients should be kept in mind when assessing high-risk patients.

Although hematogenous metastasis of cancer to the gastrointestinal track is rare, it sometime has been reported in patients with malignant melanoma and breast cancer. However, it is extremely rare for lung cancer to metastasize to the stomach, not to mention solitary gastric metastasis. Herein, the authors report a case of a 69-year-old man who was initially diagnosed with lung cancer with synchronous primary gastric cancer which proved to be lung cancer with solitary gastric metastasis after the operation.
