Background
The decrease in incidence of cervical dysplasia and carcinoma has not been as dramatic as expected with the development of improved research tools and test methods. The human papillomavirus (HPV) test alone has been suggested for screening in some countries. The National Cancer Screening Project in Korea has applied Papanicolaou smears (Pap smears) as the screening method for cervical dysplasia and carcinoma. We evaluated the value of Pap smear and HPV testing as diagnostic screening tools in a single institution.
Methods
Patients co-tested with HPV test and Pap smear simultaneously or within one month of each other were included in this study. Patients with only punch biopsy results were excluded because of sampling errors. A total of 999 cases were included, and the collected reports encompassed results of smear cytology, HPV subtypes, and histologic examinations.
Results
Sensitivity and specificity of detecting high-grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were higher for Pap smears than for HPV tests (sensitivity, 97.14%; specificity, 85.58% for Pap smears; sensitivity, 88.32%; specificity, 54.92% for HPV tests). HPV tests and Pap smears did not differ greatly in detection of low-grade squamous intraepithelial lesion (85.35% for HPV test, 80.31% for Pap smears). When atypical glandular cells were noted on Pap smears, the likelihood for histologic diagnosis of adenocarcinoma following Pap smear was higher than that of high-risk HPV test results (18.8 and 1.53, respectively).
Conclusions
Pap smears were more useful than HPV tests in the diagnosis of HSIL, SCC, and glandular lesions.

Background
Development of chemotherapeutics for the treatment of advanced hepatocellular carcinoma (HCC) has been lagging. Screening of candidate therapeutic agents by using patient-derived preclinical models may facilitate drug discovery for HCC patients.
Methods
Four primary cultured HCC cells from surgically resected tumor tissues and six HCC cell lines were used for high-throughput screening of 252 drugs from the Prestwick Chemical Library. The efficacy and mechanisms of action of the candidate anti-cancer drug were analyzed via cell viability, cell cycle assays, and western blotting.
Results
Guanabenz acetate, which has been used as an antihypertensive drug, was screened as a candidate anti-cancer agent for HCC through a drug sensitivity assay by using the primary cultured HCC cells and HCC cell lines. Guanabenz acetate reduced HCC cell viability through apoptosis and autophagy. This occurred via inhibition of growth arrest and DNA damage-inducible protein 34, increased phosphorylation of eukaryotic initiation factor 2α, increased activating transcription factor 4, and cell cycle arrest.
Conclusions
Guanabenz acetate induces endoplasmic reticulum stress–related cell death in HCC and may be repositioned as an anti-cancer therapeutic agent for HCC patients.

Abstract PDF

Preoperative radiotherapy may improve the resectability and subsequent local control of rectal cancers. However, the extent of radiation induced regression in these tumours varies widely between individuals. To date no reliable predictive marker of radiation sensitivity in rectal cancer has been identified. At the cellular level, radiation injury initiates a complex molecular network of DNA damage response (DDR) pathways that leads to cell cycle arrest, attempts at re-constituting the damaged DNA and should this fail, then apoptosis. This review presents the details which suggest the roles of DNA mismatch repair proteins, the lack of which define a distinct subset of colorectal cancers with microsatellite instability (MSI), in the DDR pathways. Hence routine assessment of the MSI status in rectal cancers may potentially serve as a predictor of radiotherapy response, thereby improving patient stratification in the administration of this otherwise toxic treatment.

Abstract PDF: Injuries from sea urchins are induced by from penetration of the calcareous spines into the skin. Apart from the transient episode of excruciating pain, there is usually no residual disability. Complications arise, however, when spines are embedded over bony prominences, or within joints. Two cases are reported with injury and protracted disability of fingers resulting from contact with the purple sea urchin, Anthocidaris crassispina, a common echinoderm inhabitant of the Korean east coast. After a latent period of several months in both cases, Case 1 presented as caseating granulomas in the synovium and case 2 exhibited as the usual soft tissue nonsynovial foreign body and noncaseating granulomas. There appears to be a paucity of published data regarding the effects of puncture wounds caused by the spines of this animal. The granulomas have appeared after a latent interval of several months in a proportion of the sufferers, suggests a delayed hyperserisitivity reaction similar to that produced by Mycobacterium species.

Abstract PDF: Transbronchial fine needle aspiration(TBNA) is one of the cytologic methods in diagnosing lung cancers. TBNA can be used in cases of hilar, mediastinal or lung masses adjacent to the bronchi. We analyzed and compaired the findings of 27 cases of TBNA and bronchial washing and brushing(BW/BB) in lung cancers confirmed by either biopsy or surgical resection between Jun, 1996 and May, 1997 in Asan Medical Center. They were 18 cases of non-small cell carcinomas(eight squamous cell carcinomas, nine adenocarcinomas, and one large cell undifferentiated carcinoma), eight cases of small cell carcinomas, and one case of metastatic hepatocellular carcinoma. The sensitivity of TBNA was 37%(10/27) and false negative was 63%(17/27). Although the sensitivity of BW/BB was 56%(15/27), it was not different statistically from that of TBNA(Chi square, p=0.38). Overall sensitivity of TBNA and BW/BB in this series was 70%(19/27). Forty-seven percent of false negative TBNA(8/17) were positive in BW/BB. The findings suggest that the addition of TBNA to the standard BW/BB increases diagnostic yield in cytologic diagnosis of lung cancer.

Abstract PDF: Fine needle aspiration cytology (FNAC) has been known as a very sensitive and effective method for preoperative diagnosis. We studied cases preoperatively diagnosed by FNAC and confirmed by the histopathologic examination to define the effectiveness of FNAC. A total of 567 cases including breast, thyroid gland, lymph node, and soft tissue confirmed histologically after FNAC were enrolled, among 2,844 FNAC cases from January 1996 to March 2000. Overall sensitivity and specificity of FNAC were 93% and 100%, respectively. Sensitivity and specificity of FNAC by sites or organs were 91% and 100% in breast, 100% and 100% in thyroid, 97% and 100% in lymph node, and 71% and 100% in soft tissue, respectively. Nine cases showed diagnostic discrepancy; eight cases of sampling error and one case of interpretation error. Five cases, diagnosed as fibrocystic change at FNAC but invasive ductal carcinoma after the histopathologic examination, were categorized as sampling error due to the presence of diffuse fibrosis or deep seated location. One case of breast, diagnosed descriptively as atypical ductal and stromal cells suggesting invasive ductal carcinoma at FNAC but malignant phyllodes tumor histologically, was categorized as interpretation error. Other cases of sampling errors were two cases of soft tissue, a case of lymph node, and a case of salivary gland.

Abstract PDF: OBJECTIVE: The sensitivity of the AutoPap Primary Screening System with Location-Guided Screening (AutoPap LGS) for identifying atypical cells in cervicovaginal smears was evaluated. METHODS: Two hundred forty one slides with atypical cervical cytology randomly sampled were rescreened both manually and by the AutoPap LGS. The AutoPap LGS localized the atypical cells as 15 fields of view(FOVs), which were reexamined by manual review. The sensitivity was also evaluated in accordance with the cellularity of the smears. RESULTS: The AutoPap LGS successfully processed 232 out of 241 slides. The sensitivity of the AutoPap LGS identifying the atypical cells in successfully processed slides was 97.4%(226/232). The false negative rate was 2.6%(6/232). There was no false negative case in high grade squamous intraepithelial lesion (HSIL) or squamous cell carcinoma(SCC) smears in the AutoPap LGS. The FOVs localized the diagnostic-atypical cells in 97.8%(221/226). The number of diagnostic-atypical FOVs was increased in higher-degree of atypical cytology. The AutoPap LGS localized the atypical cells in 100% of adequately cellular smears and in 92.5% even in low cellular smears. CONCLUSION: The AutoPap LGS showed relatively good sensitivity to detect atypical cells. It can be a valuable system to localize atypical cells, especially in HSIL or cancer slides, even in smears with low cellularity.

Abstract PDF: To analyze the accuracy and usefulness of sputum cytology as a screening method, 103 cases of histologically proven lung cancer registered from 1998 to 2000 at Kangbuk Samsung Hospital were retrospectively examined. We reviewed the original cytologic and surgical diagnoses for the cases, and the cytology slides of all cytologically negative cases. The overall sensitivity of sputum cytology was 0.83 ; the sensitivity of prebronchoscopy sputum cytology for bronchogenic carcinoma was 0.87. Central tumor location (P=0.002), tumor size (>2.4 cm), (P=0.027) and the number of sputum samples (> or =3) (P=0.001) were associated with a positive cytologic diagnosis. Of the 18 cytologically negative cases, 9 cases (38% of smears) were determined to be insufficient for diagnosis, due strictly to low cellularity and saliva. After a review of the cytology slides of cytologically negative cases, we identified several atypical clusters in one case of bronchioloalveolar carcinoma. This negativity was thus attributed to an interpretation error (1/18, 5.6%). Our results suggest that its sensitivity is more strongly related to the specimen adequacy and the times of sampling than to interpretation error. In terms of sensitivity, specificity, accessibility, cost, and morbidity associated with the screening tests, sputum cytology was found to be an accurate effective screening method for lung cancer.

Abstract PDF: Complete androgen insensitivity syndrome (CAIS) is a rare disorder sometimes referred to as male pseudohermaphroditism. This syndrome is characterized by a 46,XY karyotype with internal bilateral testes, female external genitalia, absence or scantiness of pubic and axillary hair and normal breast development. A variety of gonadal tumors can develop in individuals with CAIS. A 57-year-old patient was admitted to urology with intermittent gross hematuria for one month. CT revealed a left ureteric mass, measuring 2.5 x 2 cm. Ureteroscopic biopsy was performed and the result was a diagnosis of high grade urothelial carcinoma. The patient underwent laparotomy which revealed slightly enlarged gonads in the pelvic cavity. However, a uterus and fallopian tubes were not identified. Left nephroureterectomy and bilateral gonadectomy were performed. The right gonad measured 3.9 x 2.5 x 2 cm and the cut surface showed a well circumscribed, firm, brownish gray colored 2 x 1.8 cm sized nodule. Microscopically, this nodule consisted of uniform and solid tubules containing immature Sertoli cells and Leydig cells which were both positive for alpha-inhibin. The left gonad measured 3.5 x 2 x 1.9 cm and showed atrophic testicular tissue.
