Background: To evaluate the overtreatment rate with the see and treat approach in the management of women with abnormal cervical cytology. Materials and Methods: A retrospective review of patients with abnormal cervical cytology who underwent S&T at MSMC between January 2008 and December 2012 was conducted. Loop electrosurgical excision procedure (LEEP), histological results, cytology and colposcopic impression were analyzed to evaluate overtreatment rate, cyto-histologic correlation and related factors. Results: Average age of S&T cases was 42 years. Ninety seven percents were referred from affiliated health care providers. The study revealed 83.2% patients had HSIL or higher from cervical cytology. Correlation between HSIL and final histology was relatively low at 75% compared to other studies. Overtreatment rate was 28%. Conclusions: S&T was done in 197 patients in a tertiary care health facility with patient satisfaction. Overtreatment occurred, but the rate can be reduced with appropriate recommendations. HSIL Pap smears should be reexamined before S&T while low grade and lesser colposcopic impression groups should obtain conventional colposcopic approach for patient future reproductive benefit.

Background: To investigate the indications of loop electrosurgical excision procedure (LEEP) and its overtreatment rates for the see and treat and three step strategies in cases of atypical squamous cells of undetermined cytology (ASC-US) and low grade intraepithelial neoplasia (LGSIL) cytology. Materials and Methods: We retrospectively analyzed colposcopy directed biopsy (CDB) and LEEP results of 176 paients with ASC-US or LGSIL cytologies who underwent colposcopic examination. Results: Initial cytologies were ASCUS in 120 women and LGSIL in 56. According to the see and treat approach immediate LEEP was performed for38 women. Among the remaining 138 women, LEEP was performed for 32 whose CDB results revealed CIN2/3 lesions. In the see and treat group the recognition of CIN2/3 was found to be 39.4%. The overtreatment rate was 60% as compared to 25% in the three step group. In CDB group detection of CIN 2 or greater lesions increased with 3 or more biopsies. Conclusions: In patients with ASC-US/LGSIL cytologies CDB should be performed before LEEP to prevent overtreatment, with attention to all suspected areas and more than 2 biopsies taken.

The aim of this study was to evaluate the outcomes of women with high-grade squamous intraepithelial lesion (HSIL) smears who had undergone the "see and treat" approach compared to those who underwent a conventional approach. The records of women with HSIL smears undergoing colposcopy at Srinagarind Hospital were reviewed. In those undergoing the conventional approach, the final histological diagnosis was made on the most severe histological results obtained after initial colposcopy. In the "see and treat" group, the final histological diagnosis was made on the examination of LEEP specimens obtained after initial colposcopy. Overtreatment in the see and treat group was defined as the LEEP specimens containing cervical intraepithelial neoplasia (CIN) 1 or less. During the study period, 302 women with HSIL underwent colposcopy. Twenty (6.6%) were nulliparous. One hundred and ninety-four (64.2%) underwent conventional management while the remaining 108 (35.8%) received the see and treat management. The prevalence of underlying high-grade lesions in women undergoing the conventional approach was significantly higher than that observed among women undergoing the see and treat approach (89.2% and 47.2%, respectively, P<0.001). The overtreatment rate in the see and treat group was 52.8%. Multivariate analysis revealed that only parity status was a statistically significant factor for predicting the overtreatment after undergoing the see and treat approach. In conclusion, the overtreatment rate among women undergoing see and treat in this study is notably high and therefore this approach should not be routinely practiced.

Cytologic features of inflammatory pseudotumor of the lung have not been described frequently. We report fine needle aspiration cytologic(FNAC) finding of a case of inflammatory pseudotumor misdiagnosed as adenocarcinoma in a 63-year-old man. The FNAC displayed a mixture of histiocytes, myofibroblasts, pneumocytes, and plasma cells. Some histiocytes and myofibroblasts had large nuclei with irregular nuclear membrane and prominent nucleoli, which mislead the diagnosis on adenocarcinoma on FNAC. The heterogeneous cell population is the unique cytologic features of inflammatory pseudotumor, which are helpful to distinguish it from other circumscribed benign and malignant lesions. Familiarity with these features is essential to avoid misdiagnosis and possible overtreatment.

The spaced dentition is a common clinical finding. The careful analysis of clinically spaced dentition is a necessity for effective treatment planning. Spaced dentition often exists in the presence of intact teeth. Therefore, special care should be taken in order to obtain the most successful esthetic effect and to prevent overtreatment as well. The aesthetic restorative dental treatment using the porcelain laminate veneers is getting more popular than the complex orthodontic treatment, and prosthetic solutions that require sacrifice of sound tooth structure. The physical strength of porcelain laminate veneers is not as good as porcelain fused metal crowns, and more researches are needed in the field of bonding between composite cement and porcelain laminate veneer. However, the esthetic results from this unprepared porcelain laminate veneers were satisfactory with Authentic (Ceramay, Germany) pressable ceramic technique and resin cement (Rely X Veneer, 3M). This article deals with 2 cases of unprepared porcelain laminate veneers on anterior teeth.

Maintaining the postoperative quality of life (QOL) while ensuring curability without overtreatment is important in the treatment of early gastric cancer. Postoperative QOL is anticipated to be maintained through minimally invasive function-preserving gastrectomy in early gastric cancer. The concept of the sentinel lymph node (SN) basin is essential to maintain the curability of early gastric cancer using minimally invasive function-preserving gastrectomy. However, additional resection after surgery is difficult to perform in gastric cancer. Thus, the SN basin theory is important. Recently, a multicenter randomized phase III trial in South Korea (SENORITA trial) proved that laparoscopic sentinel node navigation surgery (LSNNS) for stomach preservation results in better postoperative QOL compared with standard gastrectomy in patients with early gastric cancer. LSNNS contributes to patients' QOL based on the concept that curability is not impaired. A multicenter nonrandomized phase III trial is ongoing in Japan, and oncologic safety is expected to be demonstrated. LSNNS has been established as a treatment option for selected patients with early gastric cancer, and its application will become widespread in the future.

Ductal carcinoma in situ (DCIS) accounts for approximately 30% of new breast cancer diagnoses. However, our understanding of how normal breast tissue evolves into DCIS and invasive cancers remains insufficient. Further, conclusions regarding the mechanisms of disease progression in terms of histopathology, genetics, and radiology are often conflicting and have implications for treatment planning. Moreover, the increase in DCIS diagnoses since the adoption of organized breast cancer screening programs has raised concerns about overdiagnosis and subsequent overtreatment. Active monitoring, a nonsurgical management strategy for DCIS, avoids surgery in favor of close imaging follow-up to de-escalate therapy and provides more treatment options. However, the two major challenges in active monitoring are identifying occult invasive cancer and patients at risk of invasive cancer progression. Subsequently, four prospective active monitoring trials are ongoing to determine the feasibility of active monitoring and refine the patient eligibility criteria and follow-up intervals. Radiologists play a major role in determining eligibility for active monitoring and reviewing surveillance images for disease progression. Trial results published over the next few years would support a new era of multidisciplinary DCIS care.

Accurately estimating survival times in terminal cancer patients is very difficult for palliative care clinicians. But a reasonably accurate estimate of survival would permit the medical team to : Plan the ideal therapeutic strategy between overtreatment and too early discontinuation of specific therapy. Answer any questions asked by the patient or family. Organize adequate assistance for the patient concerned. Decide on the eligibility of the patient for clinical trials and whether to begin a treatment, the effects of which will not be immediate. This case was a 79 year-old male patient with colon cancer. He complained of dry mouth, anorexia, weight loss and showed KPS $40{\sim}50$ on admission day. 40 days later he died. To improve patient/family quality of life, it is necessary to improve the ability to estimate accurately a patient's length of survival.

Solitary fibrous tumor on the pleura is rare but should be included in the differential diagnosis on a peripheral pulmonary nodule. Cytologic features of solitary fibrous tumor of the pleura is not familar to the pathologist and may be misdiagnosed as malignancy. We report fine needle aspiration cytologic(FNAC) findings of a case of solitary fibrous tumor misdiagnosed as adenocarcinoma in a 48-year-old woman. The FNAC displayed a mixture of bland-looking spindle cells and clusters of epithelioid cells, which have hyperchromatic nuclei with prominent nucleoli. The helpful finding to distinguish It from other circumscribed benign and malignant lesions is the presence of fibromyxoid matrix admixed with blood vessels and thin collagen fibers. Familiarity with these features is essential to avoid misdiagnosis and overtreatment.
