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 factors in the disease-free interval (DFI) of metachronous pulmonary metastasis from rectal cancer.

METHODSClinical data of 92 patients with metachronous pulmonary metastasis from rectal cancer in the Department of Colorectal Surgery at the Changhai Hospital of the Second Military Medical University from January 2001 to December 2013 were analyzed retrospectively. Univariate and multivariate analysis were performed to find the factors affecting disease-free interval of metachronous pulmonary metastasis from rectal cancer using Log-rank test and Cox proportional hazards model, respectively.

RESULTSThe median age of all the cases was 61 (range, 26-81) years. Of the 92 cases, 59 were males and 33 were females. Thirty-six cases were confirmed to have <5 cm distance from lower margin to dentate line. Forty-four cases were examined to have 5 μg/L carcinoembryonic antigen(CEA) level. Of these cases reviewed pathologically, 69 cases were adenocarcinoma, 23 were mucinous adenocarcinoma; 19 cases had stage T1-2 lesions, 73 had stage T3-4 lesions; 43 cases had stage N0 metastasis, 49 had stage N1-2 metastasis. Thirty cases received preoperative radiotherapy, 63 cases received postoperative chemotherapy. The median follow up time of all the cases was 62(range, 3-140) months. The DFI of all the cases was (25.9±21.0) months. Univariate Log-rank test indicated that the factors associated with the disease-free interval of metachronous pulmonary metastasis of rectal cancer were location of the tumor(χ(2)=4.496, P=0.034), preoperative CEA level (χ(2)=5.553, P=0.018), T stage (χ(2)=5.796, P=0.016), N stage (χ(2)=6.780, P=0.009), preoperative neoadjuvant radiotherapy (χ(2)=11.718, P=0.001) and postoperative adjuvant chemotherapy (χ(2)=9.214, P=0.002). A shorter distance from lower margin to dentate line(<5 cm), a lower preoperative CEA level(<5 μg/L), advanced T stage lesions(T3-4), advanced N stage metastasis(N1-2), no use of preoperative radiotherapy and use of postoperative chemotherapy were associated with shorter DFI of patients with metachronous pulmonary metastasis from rectal cancer. Multivariate analysis showed that N stage(OR=0.525, 95% CI: 0.309-0.891, P=0.017), location of the tumor (OR=1.770, 95% CI:1.115-2.812, P=0.016) and preoperative neoadjuvant radiotherapy (OR=1.976, 95% CI:1.228-3.401, P=0.006) were the independent risk factors associated with the disease-free interval of metachronous pulmonary metastasis from rectal cancer.

CONCLUSIONSAdvanced N stage, low location of the tumor and no use of preoperative neoadjuvant radiotherapy are risk factors of shorter disease-free interval of metachronous pulmonary metastasis from rectal cancer.

A 59-year-old man was admitted to the Department of Ear, Nose and Throat with a complaint of six-month history of left facial numbness and toothache. There was no special previous medical history in addition to smoking. No obvious abnormality in routine electrocardiogram, chest X-ray, abdominal B ultrasound were found. (1) CT scans showed heterogeneous shadows in maxillary sinus with the lesions on the left max- illary bone and evidently destruction of alveolar bone. The histopathological examination revealed bone tissue which was partly covered by an intact adenocarcinoma cell. (2) Immunohistochemical staining foe CK7, CD117, thyroid transcription factor-1, and novel aspartic proteinase A were positive and thus compatible with metastatic lung adenocarcinoma. (3) Chest CT scans showed a 1 cm x 2 cm mass on the superior lobe of the left lung, with destruction of sternum and rib, confirming that the lesions in the paranasal sinuses were lung cancer metastases. Therefore, this patient conclusively diagnosed as lung adenocarcinoma with multiple bone metastases.

Vaginal cancer is rare worldwide and represents 2% of all gynaecological cancers in Singapore. Primary vaginal malignancies are rare and vaginal metastases constitute the majority of vaginal malignancies. Most of these metastases arise from the cervix, endometrium or ovary, although they can also metastasise from distant sites such as the colon, breast and pancreas. We report a rare case of vaginal metastasis in a patient with previous gastric and rectal adenocarcinomas. An 89-year-old woman with a history of gastric and rectal malignancy presented with postmenopausal bleeding. A 2-cm vaginal tumour at the introitus was discovered upon examination. This case demonstrates the importance of performing a gynaecological examination during follow-up for patients with a history of malignancy. The prognosis for vaginal metastasis is poor, as it is often associated with disseminated disease. Depending on the extent of the lesions, radiotherapy or surgery can be considered.

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.

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.

OBJECTIVETo study the expression of arginase-1 (Arg-1), glypican-3 (GPC3), hepatocyte paraffin antigen 1 (HepPar-1) and alpha-fetoprotein (AFP) in hepatocellular carcinoma (HCC), benign liver lesions (BLL) and metastatic carcinoma (MC), and their applications in diagnosis and differential diagnosis.

METHODSImmunohistochemical study (EnVision method) for Arg-1, GPC3, HepPar-1 and AFP was carried out in three groups of liver lesions, including 85 cases of HCC, 35 cases of BLL and 19 cases of MC. The relationship between expression of Arg-1, GPC3, HepPar-1 and AFP and clinicopathologic features in HCC was also analyzed.

RESULTSThe positive expression rate of Arg-1 was 90.6% (79/85) in HCC and 100% (35/35) in BLL. Arg-1 expression was observed in 1 of the 19 cases of MC studied. The positive expression rate of GPC3 was 82.4% (70/85) in HCC, 5.3% (1/19) in MC and 0 (0/35) in BLL. The positive expression rate of AFP was 47.1% (40/85) in HCC and 0 in BLL or MC. The positive expression rate of HepPar-1 was 72.9% (62/85) in HCC, 100% (35/35) in BLL and 2/19 in MC. Arg-1 has a higher sensitivity in highlighting hepatocellular lesions than AFP and HepPar-1 (P=0.000 versus P=0.002). The specificity of GPC3 expression in HCC was 98.1%.

CONCLUSIONSArg-1 is a sensitive hepatocellular marker in delineation of liver lesions.GPC3 is a relatively specific marker in diagnosis of HCC.
