OBJECTIVE: To compare the quality of tissue from punch biopsy forceps (PB group) with round loop electrode (LE group) in colposcopically directed biopsy along with the evaluation of pain associated with each procedure. METHODS: Patients with abnormal cervical cytologic results and abnormal colposcopic findings were enrolled into a randomized trial into either a PB group or LE group. The quality of tissue was evaluated in regards to the size of tissue, site of tissue, and tissue damage. Each quality had 1 to 3 points and the sum of each quality contributed to the total tissue score that ranged from 3 to 9. Pain associated with each procedure was assessed by a visual analog scale (VAS). This was a clinical trial study and was registered at www.clinicaltrials.in.th (Identifier: TCTR20160404001). RESULTS: Ninety-six women who met all eligibility requirements were enrolled in the study. Forty-eight patients were randomly assigned to the PB group and 48 patients were randomized into the LE group. The characteristics of the patients were similar between the 2 groups with the exception of the median age. The median total tissue score was 8 points in the LE group which was more than the median of 7 points in the PB group with a statistically significant difference (p=0.014). However, the median VAS pain score in both groups was 3.4 (p=0.82). CONCLUSION: The quality of cervical tissues obtained from biopsy with a round loop electrode was better than the punch biopsy forceps with no difference in the level of pain.

Purpose: The standard treatment for locally advanced rectal cancer (LARC) is neoadjuvant chemoradiation (nCRT) followed by surgery. Several parameters are associated with patient survival in LARC. One of these parameters is tumor regression grade (TRG); however, the significance of TRG remains controversial. In this study, we aimed to examine the correlations of TRG with 5-year overall (OS) and relapse-free survival (RFS) and identify other factors that influence the survival rates in LARC after nCRT followed by surgery. Methods: This retrospective study included 104 patients diagnosed with LARC who underwent nCRT followed by surgery at Songklanagarind Hospital from January 2010 to December 2015. All patients received fluoropyrimidine-based chemotherapy at a total dose of 45.0 to 50.4 Gy in 25 daily fractions. Tumor response was evaluated using the 5-tier Mandard TRG classification. TRG was categorized into good (TRG 1–2) and poor (TRG 3–5) responses. Results: TRG (classified by either the 5-tier classification system or the 2-group classification system) was not correlated with 5-year OS or RFS. The 5-year OS rates were 80.0%, 54.5%, 80.8%, and 67.4% in patients with TRG 1, 2, 3, and 4, respectively (P=0.22). Poorly differentiated rectal cancer and systemic metastasis were associated with poor 5-year OS. Intraoperative tumor perforation, poor differentiation, and perineural invasion were correlated with inferior 5-year RFS. Conclusion: TRG was probably not associated with either 5-year OS or RFS; however, poor differentiation and systemic metastasis were strongly associated with poor 5-year OS.

Background/Aims: Narrow Band Imaging (NBI) International Colorectal Endoscopic (NICE) and Workgroup Serrated Polyps and Polyposis (WASP) classifications were developed for optical diagnosis of neoplastic and sessile serrated polyps, respectively. Near-focus NBI with NICE combined with WASP criteria for optical diagnosis of colonic polyps has not yet been evaluated. We aimed to compare the accuracy of near-focus NBI (group A) with normal-focus NBI (group B) in real-time optical diagnosis of colorectal polyps using combined NICE and WASP criteria. Methods: Among 362 patients, 118 with 227 polyps were recruited. Groups A and B included 62 patients with 130 polyps (three lost polyps) and 56 patients with 106 polyps (six lost polyps), respectively. Optical diagnoses were compared with pathological reports. Results: The accuracy of optical diagnosis of neoplastic polyps in groups A and B was not significantly different (76% vs. 71%, p=0.52). WASP criteria provided all false positive diagnoses of sessile polyps as serrated polyps in 31 (16.2%) patients. Conclusions: Near-focus NBI was not superior to normal-focus NBI in optical diagnostics of neoplastic polyps using NICE criteria. In our study, WASP classification yielded all false positives in the diagnosis of sessile serrated adenomas/polyps. Routine real-life optical diagnosis of polyps is still unadvisable.
