Purpose
This study aimed to compare treatment outcomes and toxicity profile between imaged-guided brachytherapy (IGBT) versus conventional brachytherapy (CBT) performed by the same practitioner during the same time period.
Materials and Methods
Medical records of 104 eligible patients who underwent brachytherapy for locally advanced cervical cancer were retrospectively reviewed. Fifty patients (48.1%) underwent IGBT, and 54 (51.9%) patients underwent CBT. All patients underwent concurrent chemoradiation with cisplatin. High-dose-rate intracavitary brachytherapy with dose prescription of 25-30 Gy in 4-6 fractions was performed for all patients. Late lower gastrointestinal (GI) and urinary toxicities occurred more than 3 months after the end of brachytherapy were included for comparative and dosimetric analyses.
Results
The median follow-up period was 18.33 months (range, 3.25 to 38.43 months). There were no differences in oncologic outcomes between the two groups. The IGBT group had lower rate of actuarial grade ≥ 3 toxicity than the CBT group (2-year, 4.5% vs. 25.7%; p=0.030). Cumulative equieffective D2cc of sigmoid colon was significantly correlated with grade ≥ 2 lower GI toxicity (p=0.033), while equieffective D2cc of rectum (p=0.055) and bladder (p=0.069) showed marginal significance with corresponding grade ≥ 2 toxicities in the IGBT group. Half of grade ≥ 3 lower GI toxicities impacted GI tract above the rectum. Optimal thresholds of cumulative D2cc of sigmoid colon and rectum were 69.7 Gy and 70.8 Gy, respectively, for grade ≥ 2 lower GI toxicity.
Conclusion
IGBT showed superior toxicity profile to CBT. Evaluating the dose to the GI tract above rectum by IGBT might prevent some toxicities.

Venous Invasion in Colorectal Cancer: Impact of Morphologic Findings on Detection Rate
Chungsu Hwang, Sojeong Lee, Ahrong Kim, Young-Geum Kim, Sang-Jeong Ahn, Do Youn Park
Cancer Res Treat. 2016;48(4):1222-1228.   Published online February 12, 2016
DOI: https://doi.org/10.4143/crt.2015.429
AbstractAbstract PDFPubReaderePub
Purpose
Venous invasion (VI) is widely accepted as a poor prognostic factor in colorectal cancer (CRC), and is indicated as a high-risk factor determining the use of adjuvant chemotherapy in CRC. However, there is marked interobserver and intraobserver variability in VI identification and marked variability in the real prevalence of VI in CRC.
Materials and Methods
We investigated the detection rate of VI in 93 consecutive cases of T3 or T4 CRC based on the following: original pathology report, review of hematoxylin and eosin (H&E) slides with attention to the “protruding tongue” and “orphan arteriole” signs, and elastic stain as the gold standard.
Results
Overall, the detection rate of VI was significantly increased as follows: 14/93 (15.1%) in the original pathology report, 38/93 (40.9%) in review of H&E slides with attention to the “protruding tongue” and “orphan arteriole” signs, and 45/93 (48.4%) using elastic stain. VI detection based on morphologic features showed 77.8% sensitivity and 91.1% specificity and showed a linear correlation (Spearman correlation coefficient, 0.727; p < 0.001) with VI detected by elastic stain. In addition, improved agreement between detection methods (detection on the basis of morphologic features, κ=0.719 vs. original pathology report, κ=0.318) was observed using kappa statistics.
Conclusion
Slide review with special attention to the “protruding tongue” and “orphan arteriole” signs could be used for better identification of VI in CRC in routine surgical practice.

Preliminary Suggestion about Staging of Anorectal Malignant Melanoma May Be Used to Predict Prognosis
Won Young Chae, Jong Lyul Lee, Dong-Hyung Cho, Chang Sik Yu, Jin Roh, Jin Cheon Kim
Cancer Res Treat. 2016;48(1):240-249.   Published online March 6, 2015
DOI: https://doi.org/10.4143/crt.2014.305
AbstractAbstract PDFPubReaderePub
Purpose
Anorectal malignant melanomas (AMM) are rare and have poor survival. The study aims to evaluate the clinicopathologic characteristics and outcomes of patients with AMM, and to devise a staging system predictive of survival outcome.
Materials and Methods
This was a retrospective study of 28 patients diagnosed with, and treated for AMM. Patients classified by clinical staging of mucosal melanoma (MM) were reclassified via rectal and anal TNM staging. Survival outcomes were compared among patients grouped by the three different staging systems.
Results
The three staging systems were equated with similar figures for 5-year overall survival (OS) and 5-year disease-free survival (DFS) of patients diagnosed with stage I disease. Patients (n=19) diagnosed with MM stage II disease were reclassified by rectal TNM staging into three subgroups: IIIA, IIIB, and IIIC. For these patients, both 5-year OS and 5-year DFS differed significantly between the subgroups IIIA and IIIC (OS: IIIA vs. IIIC, 66.7% vs. 0%, p=0.002; DFS: IIIA vs. IIIC, 51.4% vs. 0%, p < 0.001).
Conclusion
The accuracy of prognosis in patients diagnosed with AMM and lymph node metastasis has improved by using rectal TNM staging, which includes information regarding the number of lymph node metastases.

Sebastia Sabater, Meritxell Arenas, Roberto Berenguer, Ignacio Andres, Esther Jimenez-Jimenez, Ana Martos, Jesus Fernandez-Lopez, Mar Sevillano, Angeles Rovirosa
Cancer Res Treat. 2015;47(3):473-479.   Published online November 24, 2014
DOI: https://doi.org/10.4143/crt.2014.115
AbstractAbstract PDFPubReaderePub
Purpose
Association between body mass index (BMI) and doses in organs at risk during postoperative vaginal cuff brachytherapy (VCB) treatment has not been evaluated. The aim of this study was to analyse the impact of BMI on the dose delivered to bladder and rectum during high-dose-rate VCB using computed tomography (CT) scans at every fraction.
Materials and Methods
A retrospective analysis of 220 planning CT sets derived from 59 patients was conducted. Every planning CT was re-segmented and re-planned under the same parameters. Rectum and bladder dose-volume histogram values (D0.1cc, D1cc, and D2cc) were extracted and evaluated. The mean values for all applications per patient were calculated and correlated with BMI, as well as other factors influencing rectal and bladder doses. Multiple regression analysis performed to model organ at risk dose-volume parameters.
Results
According to World Health Organization (WHO), 6.8% of patients were normal, 35.6% were overweight, and 57.6% were class I obese. Median rectal doses were 133.5%, 110.9%, and 99.3% for D0.1cc, D1cc, and D2cc, respectively. The corresponding median bladder doses were 96.2%, 80.6%, and 73.3%, respectively. BMI did not show significant association with rectal doses. However, BMI did show a significant association with evaluated bladder dose metrics (D0.1cc, r=–0.366, p=0.004; D1cc, r=–0.454, p < 0.001; D2cc, r=–0.451, p < 0.001). BMI was retained in the multivariate regression models (D0.1cc, p=0.004; D1cc, p < 0.001; D2cc, p=0.001).
Conclusion
In this group of Mediterranean, overweight, and moderately obese patients, BMI showed association with lower bladder dose values, but not with rectal doses.

AbstractAbstract PDFPubReaderePub
Purpose

Anatomy of deep pelvis, narrow distal margin and tumor invasion into neighbor organ are obstacles for curative radical resection for advanced cancer of distal rectum. Technically, laparoscopic application after downstaging the tumor with preoperative concurrent chemotherapy (CCRT) may give a solution to overcome the anatomical difficulties. We compared the results of laparoscopic surgery in the patients who received CCRT with those of patients who had conventional surgery.

Materials and Methods

A continuous infusion of 5FU plus leucovorin and radiotherapy (50.4 Gy) in 28 fractions was given each patient as CCRT. They underwent D2 radical resection with TME and ANP for the rectal cancer in 4 weeks.

Results

Thirty three patients had laparoscopic resection such as LAR, colo-anal anastomosis and APR. The results were compared with 12 cases of the conventional resections. As a result of preoperative CCRT, the cancer was down-staged in 71%. Two year disease free survival was 75% and 74% in the group of conventional and laparoscopic resection, respectively (p=0.427). Ileus, voiding difficulty and leakage after surgery were not different between two groups. Weakness of ejaculation was noted in 9~11% of both groups. The DFS of the preoperative CCRT followed by radical resection in the groups with a response was more favorable than that in the group with progressive or stable disease.

Conclusion

Radical resection of advanced distal rectal cancer could be done with performing a laparoscopic assisted operation after CCRT induced down-staging. We may suggest that laparoscopic assisted resection is a good treatment option as it doesn't increase the complications and it has a compatible survival rate to conventional surgery.

Hee Chul Kim, Chang Nam Kim, Choon Sik Jeong, Chang Sik Yu, Byung Sik Kim, Hun Kyung Lee, Jin Cheon Kim
J Korean Cancer Assoc. 1998;30(3):521-526.
AbstractAbstract PDF
PURPOSE
Signet ring cell carcinoma is a rare type of adenocarcinoma in the colon and rectum. We evaluated the differences of clinical features between colorectal signet ring cell carcinoma and ordinary adenocarcinoma.
MATERIALS AND METHODS
The clincopathologic data of 13 cases with primary colorectal signet ring cell carcinoma were reviewed. The primary colorectal signet ring cell carcinoma was diagnosed when following criteria were met: 1) the tumor was primary; 2) histologic material was adequate; 3) signet ring cells represented more than 50% of the cancer.
RESULTS
Patients ranged in age from 20 to 68 (median, 45) years; 7 were male, and 6 were female. Three tumors were located in the proximal colon, 3 in the distal colon, and 7 in the rectum. There was no case that had family history. Most cases (77%) were stage III, one was stage II, and two were stage IV with peritoneal seeding. There were 9 cases that showed local recurrence or distant metastases during follow-up periods 6 cases with peritoneal seeding, 3 with bone metastases, 2 with brain metastases and 1 with pelvic recurrence (two cases had either bone and brain metastasis, and one case had bone and peritoneal seeding). Prognosis was extremely poor, and overall two years survival rate was 25%. CONCLUSION: Early onset, mode of metastasis and poor prognosis may imply the different biologic behavior of signet ring cell carcinoma, compared with ordinary adenocarcinoma. To improve outcome, early diagnosis and radical operation should be stressed.
