RESUMO
BACKGROUND: Subcutaneous emphysema (SCE) is a common complication in laparoscopic surgery. However, its precise incidence and impact on the clinical course are partially known. In this study, the incidence and risk factors of SCE were retrospectively analyzed. METHODS: Patients who underwent laparoscopic/robotic abdominal surgery (e.g., gastrointestinal, hepatobiliary, gynecologic, and urologic surgery) between October 2019 and September 2022 were retrospectively analyzed. The presence of SCE was confirmed by either conclusive findings obtained through chest/abdominal X-ray examination immediately after operation, or intraoperative palpation conducted by nurses. X-ray examination was performed in the operation room before extubation. RESULTS: A total of 2503 patients treated with laparoscopic/robotic abdominal surgery between October 2019 and September 2022 were identified and all of them were included in the analysis. SCE was confirmed in 23.1% of the patients (i.e., 577/2503). SCE was identified by X-ray examination in 97.6% of the patients. Extubation failure was observed in 10 patients; however, pneumothorax was not observed. Female sex (odds ratio [OR]: 2.09; 95% confidence interval [95%CI]: 1.69-2.57), age ≥ 80 years (OR 1.63; 95%CI 1.19-2.22), body mass index < 20 (OR 1.32; 95%CI 1.06-1.65), operation time > 360 min (OR 1.97; 95%CI 1.53-2.54), robotic surgery (OR 2.54; 95%CI 1.91-3.38), maximum intraabdominal pressure with CO2 > 15 mmHg (OR 1.79; 95%CI 1.02-3.16), and endo-tidal CO2 > 50 mmHg (OR 1.32; 95%CI 1.08-1.62)were identified as independent factors of SCE. Regarding the extubation failure due to SCE, age (OR 5.84; 95%CI 1.27-26.8) and maximum intraabdominal pressure with CO2 (OR 21.7; 95%CI 4.76-99.3) were identified as risk factors. CONCLUSION: Although the presence of SCE is associated with a low risk of severe complications, monitoring of the perioperative intraabdominal pressure is essential for performing safe laparoscopic/robotic surgery, particularly in elderly patients.

In May 2022, Hyogo Medical University Hospital introduced protocol-based pharmacotherapy management(PBPM), which is jointly planned by doctors and pharmacists, for certain cancer drug therapies. Colorectal cancer patients who underwent outpatient cancer chemotherapy in the Department of Lower Gastrointestinal Surgery from October to December 2021(before the introduction of PBPM)and from May to August 2022(after the introduction of PBPM)were retrospectively studied. The proportion of clinical examinations performed, number of prescription questions, and time taken by pharmacists to solve the prescription questions before and after the introduction of PBPM were compared. Additionally, the number of modifications made in the medical record by pharmacists on behalf of doctors in response to the prescription questions was assessed. The proportion of clinical examinations performed(clinical examinations actually performed/clinical examinations that should have been performed)improved from 93.2%(260/279)before to 98.8%(405/410)after the introduction of PBPM(p<0.001). The number of prescription questions decreased from an average of 64.7(±11.9)per month before to an average of 29.5(±3.4)per month after the introduction of PBPM. The average number of modifications made in the medical record by pharmacists on behalf of the doctors in response to the prescription questions was 25.8(±5.4)per month after the introduction of PBPM. There was no significant difference before and after the introduction of PBPM in regard to the median(interquartile range)time taken by pharmacists to solve the prescription questions (before PBPM: 1.88 minutes per case[1.70-2.28 minutes]; after PBPM: 1.71 minutes per case[1.61-2.06 minutes][p= 0.75]). The increased proportion of clinical examinations performed after the implementation of PBPM may have improved the safety of cancer drug management, and the decreased number of prescription questions is speculated to have led to a reduction in physician workload.

BACKGROUND: The role of recurrence-free survival (RFS) as a valid surrogate endpoint for overall survival (OS) in patients who underwent upfront surgery for colorectal liver metastases remains uncertain. The aim of the study was to compare the two survival measures in a nationwide cohort of upfront resected colorectal liver metastasis. METHODS: Data from patients with colorectal liver metastases without extrahepatic metastases who underwent curative surgery for liver metastases were retrieved from the Japanese nationwide database (data collection 2005-2007 and 2013-2014). RFS, OS, and survival after recurrence were estimated using the Kaplan-Meier method. The correlation (ρ) between RFS and OS was assessed using the rank correlation method combined with iterative multiple imputation, to account for censoring. As a secondary analysis, the correlation was evaluated according to adjuvant chemotherapy regimen. In sensitivity analysis, the pairwise correlation between RFS and OS was calculated. RESULTS: A total of 2385 patients with colorectal liver metastases were included. In the primary analysis, there was a moderately strong correlation between RFS and OS (ρ = 0.73, 95 per cent c.i. 0.70 to 0.76). The strength of the correlation was similar regardless of the adjuvant treatment regimen (oxaliplatin plus 5-fluorouracil: ρ = 0.72, 0.67 to 0.77; 5-fluorouracil alone: ρ = 0.72, 0.66 to 0.76; observation: ρ = 0.74, 0.69 to 0.78). The mean(s.d.) pairwise correlation coefficient between 3-year RFS and 5-year OS was 0.87(0.06). CONCLUSION: In surgically treated patients with colorectal liver metastases, there was a moderately strong correlation between RFS and OS, which was unaffected by the treatment regimen. Further validation using a trial-level analysis is required.

BACKGROUND: Total pelvic exenteration, a surgical procedure for patients with highly advanced primary and recurrent rectal cancer, is technically demanding. IMPACT OF INNOVATION: We report the utility of a transanal minimally invasive surgical approach to total pelvic exenteration. TECHNOLOGY MATERIALS AND METHODS: A 2-team approach with a laparoscopic transabdominal approach and transanal minimally invasive surgery was adopted. During the transabdominal approach in the pelvis, dissection was performed to remove the pelvic organs and visceral branches of the internal iliac vessels. The dissection goal via the transabdominal approach is the levator ani. During the transperineal approach, dissection is performed along the levator ani, and the tendinous arch of the levator ani is penetrated at the lateral side to achieve rendezvous between the 2 approaches. The levator ani is then dissected circumferentially, with identification of the internal pudendal vessels passing through the levator ani at the 4 o'clock and 8 o'clock positions, known as Alcock's canal. The anterior wall of Alcock's canal is formed by the coccygeus muscle and sacrospinous ligament, which are dissected by the transperineal approach to open Alcock's canal, thus obtaining a clear view of the internal pudendal vessels. On the anterior side, the urethra is divided with a laparoscopic linear stapler via the transperineal approach. PRELIMINARY RESULTS: Eight patients with rectal cancer underwent this procedure. The median (range) blood loss was 200 (120-1520) mL and operating time was 467 (321-833) minutes. Reoperation was performed in 1 internal hernia case; however, there were no mortalities, and there were no cases with severe complications or conversion to open surgery. CONCLUSIONS AND FUTURE DIRECTIONS: When performing total pelvic exenteration, transanal minimally invasive surgery offers direct visualization behind the tumor from the anal side and shows the deep pelvic structures, including the retroperitoneal space of the pelvic sidewall.

PURPOSE: Although ulcerative colitis-associated colorectal cancer (UC-CRC) has been described, there are few reports regarding recurrent cases of UC-CRC. In this study, we investigated the risk factors for UC-CRC recurrence. METHODS: Recurrence-free survival (RFS) was determined for 144 stage I to III cancer patients among 210 UC-CRC patients from August 2002 to August 2019. The KaplanâMeier method was used to obtain the cumulative RFS rate, and the Cox proportional hazard model was used to extract recurrence risk factors. The interaction term between cancer stage and prognostic factors specific to UC-CRC was evaluated using the Cox model. The KaplanâMeier method was applied by cancer stage to the UC-CRC-specific prognostic factors for which interaction effects were indicated. RESULTS: There were 18 cases of recurrence involving patients with stage I to III cancer, and the recurrence rate was 12.5%. The cumulative 5-year RFS rate was 87.5%. Multivariable analysis showed that age at surgery (hazard ratio (HR): 0.95, 95% CI: 0.91-0.99, p = 0.02), undifferentiated carcinoma (HR: 4.42, 95% CI: 1.13-17.24, p = 0.03), lymph node metastasis (HR: 4.11, 95% CI: 1.08-15.69, p = 0.03), and vascular invasion (HR: 8.01, 95% CI: 1.54-41.65, p = 0.01) were significant risk factors for recurrence. Patients with stage III CRC in the young adult (age < 50 years) group had a significantly worse prognosis than those in the adult (age ≥ 50 years) group (p < 0.01). CONCLUSION: Age at surgery was identified as a risk factor for UC-CRC recurrence. Young adult patients with stage III cancer may have a poor prognosis.

PURPOSE: The aim of this study was to compare the clinical characteristics of ulcerative colitis (UC) patients who underwent surgery for cancer/dysplasia with those who underwent surgery for refractory disease and to discuss the preoperative preparation for successful hand-sewn IPAA. METHODS: Patients who underwent surgery for UC between January 2014 and December 2021 at Hyogo Medical University were included in the study. A total of 443 UC surgical cases were included in the study, which comprised 188 cancer/dysplasia patients and 255 refractory patients. Clinical records were compared retrospectively. RESULTS: The proportion of surgical UC cases with cancer/dysplasia has been on the rise, accounting for approximately 40% in recent years. The duration of disease (months) was 186 (2-590) in the cancer/dysplasia group and 48 (1-580) in the refractory group (p = 0.02). UC severity (mild/moderate/severe) was 119/69/0 in the cancer/dysplasia group and 18/157/80 in the refractory group (p < 0.01). The four nutrition factors of weight (55.2 (32.7-99.6) kg: 49.9 (20.3-85.2) kg), body mass index (21.0 (13.9-32.5) kg/m2: 18.3 (11.4-34.1)kg/m2), serum albumin level (4.3 (2.7-5.0)g/dl: 3.4 (1.4-5.2)g/dl) and prognostic nutrition index (49.2 (33.2-61.2): 40.9 (17.4-61.1)) were significantly higher in the cancer/dysplasia group (p < 0.01). The degree of obesity was also significantly higher in the cancer/dysplasia group (p < 0.01). CONCLUSION: UC patients with cancer/dysplasia were more likely than refractory patients to have mild inflammation; they also had a longer duration of UC disease and better nutritional status.

BACKGROUND: Fluorouracil infusion for 46±5h from the central venous(CV)port is required for mFOLFOX6, FOLFIRI, and FOLFOXIRI in patients with advanced colorectal cancer(CRC), followed by self-removal of the needle by patients. At our hospital, outpatients were instructed for self-removal of the needle, but the results were unsatisfactory. Therefore, instructions for self-removal of the needle from the CV port have been initiated at the patient ward since April 2019, making use of a hospital stay of 3 days. PATIENTS: We retrospectively enrolled patients with chemotherapy-introduced advanced CRC from the CV port who received instructions for self-removal of the needle in the outpatient department and ward between January 2018 and December 2021. RESULTS: Of all patients with advanced CRC, 21 received instructions at the outpatient department(OP)while 67 at patient ward(PW). Incidences of successful self-removal of the needle without the aid of others were similar: 47% in OP and 52% in PW(p=0.80). However, after several additional instructions involving their families, it was higher in PW than in OP(97.0 vs 76.1%, p=0.005). Incidences of successful self-removal of the needle without the aid of others in those aged≥75/<75, and≥65/<65 years were 0%/61.1%, and 35.4%/67.5%, respectively. OP was as a risk factor for failed self-removal of the needle in the logistic regression analysis(odds ratio: 11.19, 95%CI: 1.86- 67.30). CONCLUSION: Repeated instructions involving patients' families during the hospital stay improved the incidence of successful self-removal of the needle. Involvement of patients' families from the beginning may effectively improve self- removal of the needle, particularly in the elderly patients with advanced CRC.

BACKGROUNDS: Comprehensive genomic profiling(CGP)has been covered by health insurance since June 2019. However, the clinical impact of CGP on patients with metastatic colorectal cancer(mCRC)remains unclear. To date, there are very limited reports regarding patient-oriented outcomes of CGP in mCRC. PATIENTS: A questionnaire was completed by patients with mCRC who had already received their CGP results after April 2021. Eight questions were posed, covering the degree of satisfaction and timing when CGP was conducted. RESULTS: Of the 51 patients with mCRC who had received their CGP test results by August 2021 in our department, 21 patients responded to our questionnaire. In total 66.7% patients with mCRC answered "(very)satisfied"with the CGP testing. 28.6% of the patients already knew about CGP testing before their local doctors informed them. Except for 3 patients who did not answer, 47.6% and 9.5% of patients with mCRC"agreed"and "moderately agreed"with the timing of the CGP test. CONCLUSION: Although most patients with mCRC failed to access promising new treatment via CGP, approximately half of the patients answered that they were satisfied with the CGP testing. Conversely, a few patients already knew about CGP testing before it was proposed by their doctors. Thus, the provision of information at an early stage is necessary.

JCOG-CCSG has been conducting several surgical trials and experienced several challenges. The first point is the appropriate timing of conducting the trial. Once a certain number of surgeons acquire the new technique and its utility is accepted, it suddenly becomes difficult to maintain 'equipoise' between the standard and new treatment, which may lead to poor patient accrual. Smooth preparation and commencement of the trial at an appropriate timing is necessary for its success. Second is the appropriate quality assurance of surgery. High-level quality assurance will strengthen the comparability of randomized control trials and minimize the heterogeneity among hospitals. On the other hand, it may impair the generalizability of the trial. Large observational studies help to bridge the gap of heterogeneity among hospitals. Third is the selection of an appropriate endpoint. Overall survival (OS) is the gold-standard primary endpoint; however, the number of events is much less due to more effective treatment. JCOG0212 and JCOG0404 were unable to demonstrate the non-inferiority of omission of lateral lymph node dissection and laparoscopic surgery partly due to a lack of power. Disease-free survival (DFS) is also a promising candidate for primary endpoint, but as in JCOG0603, special attention must be paid when DFS does not correlate with OS. Although careful discussion is required because the precision of the hazard ratio depends on the number of events, an alternative population-level summary of variables, including restricted mean survival time, can be considered as the primary endpoint. Future surgical trials should be planned considering these points.

INTRODUCTION: It is well known that the infectious complications and mortality rates are increased among elderly individuals with ulcerative colitis (UC) during medical treatment. However, there have been few reports on surgery in elderly individuals with UC, and some cohort studies have reported surgical complication and mortality rates similar to those in nonelderly individuals. METHODS: UC patients who underwent colectomy at the Hyogo College of Medicine between April 2012 and March 2020 were included in this study. The patients were classified as elderly (≥65) or nonelderly (<65). Characteristics and postoperative complications were analyzed and compared between the groups; possible risk factors for infectious and fatal complications were also analyzed. RESULTS: In all, 136/599 (22.7%) elderly patients were included. The incidence of infectious and fatal complications was 177/599 (29.5%) and 18/599 (3%), respectively. These complication rates were significantly higher in the elderly than the nonelderly group (p < 0.01). Age ≥65 years at surgery (OR = 2.92, 95% CI: 1.87-4.57, p < 0.01) was identified as an independent risk factor for infectious complications. Age ≥65 years at surgery (OR = 8.03, 95% CI: 2.16-29.83, p < 0.01), American Society of Anesthesiologists score ≥3 (OR = 6.00, 95% CI: 1.40-25.6 p = 0.02), and urgent/emergent surgery (OR = 16.24, 95% CI: 1.70-154.95, p = 0.02) were identified as independent risk factors for fatal complications. DISCUSSION/CONCLUSION: Age ≥65 years was identified as a risk factor for infectious and fatal complications. It is important to avoid urgent/emergent surgery in elderly patients with an ASA score >3 by emphasizing surgical and medical collaboration and optimizing the timing of surgery.

Preemptive skin treatment led by nurses and pharmacists was started for patients with metastatic colorectal cancer (mCRC)who received anti-EGFR antibody treatment. Incidence of skin-related toxicities, amount of topical moisturizers used, and administered cycles of anti-EGFR antibody were retrospectively compared between a preemptive skin treatment group and a control group. Thirty-four mCRC patients before the introduction of preemptive skin treatment led by nurses and 23 mCRC patients treated with preemptive skin treatment led by nurses were evaluated. The incidence of 6- and 12- week Grade 2 or higher skin-related toxicity was 23.5% in the control group and 8.7% in the preemptive group(p=0.18), and 67.7% in the control group and 30.4% in the preemptive group(p=0.0076), respectively. Mean amounts of moisturizer used were both lower in the control group than in the preemptive group at both 6 weeks and 7-12 weeks(6 weeks; 275 g vs 550 g, p=0.036, 7-12 weeks; 575 g vs 1,175 g, p=0.013). However, the amount of topical steroid used was similar in both groups. Preemptive moisturizer skin treatment led by nurses and pharmacists may decrease the incidence of skin- related toxicity.

The anatomical spread of lymph node (LN) metastasis is of practical importance in the surgical management of colon cancer (CC). We examined the effect of KRAS, BRAF, and microsatellite instability (MSI) on LN count and anatomical spread pattern in stage III CC. We determined KRAS, BRAF, and MSI status from stage III CC patients. Biomarker status was correlated with LN count and anatomical spread pattern, which was classified as sequential or skipped. Relapse-free survival (RFS) was estimated using Kaplan-Meier method, and correlations were assessed using log-rank and Cox regression analyses. We analyzed 369 stage III CC patients. The proportion of KRAS mutant (mt), BRAF mt, and MSI-high (H) were 44.2% (163/344), 6.8% (25/344), and 6.8% (25/344), respectively. The mean number of metastatic LN was higher in microsatellite-stable (MSS) compared with MSI patients (3.5 vs. 2.7, P = .0406), although no differences were observed in accordance with KRAS or BRAF status. Interestingly, patients with BRAF mt and MSI-H were less likely to harbor skipped metastatic LN (9.3% vs 20% and 4% vs 10.5% compared with BRAF wild-type (wt) and MSS, respectively), but KRAS status did not predict anatomical spread pattern. Patients with KRAS wt and MSI-H showed superior RFS compared with KRAS mt and MSS patients, respectively, whereas BRAF status did not affect RFS. Differences exist in the anatomical pattern of invaded LN in accordance with the molecular status of stage III CC. Patients with MSI-H CC have less invaded and skipped LN, suggesting that a tailored surgical approach is possible.

BACKGROUND: Lateral pelvic lymph node dissection (LLND) combined with removal of the internal iliac vessels is a challenging surgical procedure in minimally invasive surgery. We herein report our dissection approach and short-term outcomes. METHODS: We conducted a study on rectal cancer patients who underwent laparoscopuic LLND combined with removal of the internal iliac vessels at our institution in March 2017-December 2019. In performing the surgery, we identified and dissected along the three pelvic sidewall fasciae (ureterohypogastric, umbilical prevesical and parietal pelvic fascia), located the internal ilial vein at the level of the common iliac vessels and carried out our dissection along the medial anterior surface of the internal iliac before transecting the vein. The duration of LLND was recorded as was the blood loss. RESULTS: There were 16 patients (10 males, mean age 65.4 ± 10.8 years). Five patients had primary surgery, and 11 had surgery for recurrence. The median blood loss of LLND was 10 ml (range, 0-250 ml), the median operating time was 173 min (range, 65-358 min), and post-operative complications were relatively mild. Seven of 16 patients (43.8%) were diagnosed with positive lateral nodes. The 2-year local recurrence-free and disease-free survival rates were 87.5% and 58.0%. CONCLUSION: Recognizing the pelvic anatomical points illustrated in the present study contributes to the surgical safety of LLND combined with removal of the internal iliac vessels.

Cancer patients, especially active cancer patients have high risk of cancer-associated venous thromboembolism(VTE). Virchow's triad, hyper-coagulability, endothelial cell damage, and blood stasis are often found during cancer treatment. Tissue factor expressed on tumor cells activate coagulation, and decrease in antithrombotic activity by topical inflammation and platelet activation increase the risk of VTE. The risk of VTE is further enhanced by surgical intervention and chemotherapy. Anticoagulation is the most important treatment, however warfarin is not suitable for active cancer patients due to drug- drug interaction and gastrointestinal toxicity. In the Western countries, low molecular weight heparin (LMWH) is the standard choice for cancer-associated VTE. During anticoagulation, risk of recurrence of VTE and major bleeding is very high. Recently, direct oral anticoagulant(DOAC)has been introduced and widely used in Japan after the evidence of DOACs in cancer patients. Gastrointestinal bleeding is one of the frequent adverse events during DOAC treatment. Drug-drug interaction such as P-glycoprotein and CYP3A4 must be considered for safety treatment.

A 55-year-old man was referred for surgery after colonoscopy revealed type 3 advanced lower rectal cancer in the lower rectum. CT and MRI scan showed no distant metastasis but on the left side of the rectum, there was a 34×30 mm large mass suspicious of lymph node metastasis, which had left-sided wall pelvic fascia invasion. We performed preoperative chemoradiotherapy(CRT)to ensure a secure surgical margin. As a result, the tumor volume was reduced and robot-assisted rectal amputation and bilateral lateral lymph node dissection were performed using a combined transperineal speculum approach. The pathological results showed that circumferential resection margin of 3 mm was secured. The lymph nodes on the left side of the rectum were mostly fibrotic and the tumor component had almost disappeared. Preoperative CRT is useful for securing the surgical margin. The multidisciplinary treatment including extended surgery enabled the curative resection of even highly advanced rectal cancer.

Treatment for late-stage cancer patients should be discussed depending on the patients' will, however it is not sometimes fully discussed in our daily practice. Based on this background, the information-sharing tool for metastatic colorectal cancer patients, who are refractory to first-line and second-line chemotherapy and/or who are given a year to live, has been introduced in our university hospital since November 2019. To evaluate the utility of this tool, the influence of the tools on the outcome of the patients was evaluated. Regarding the comparison between the patients before and after the introduction of the information-sharing tool, the period between the day of the consent to the DNAR between the day of the death is longer in the patients after the introduction than those before the introduction(median 43 vs 6 days, p=0.025). The introduction of the information-sharing tool can provide the metastatic colorectal cancer patients with more opportunities to discuss how to spend the rest of their lives and with longer time at the place where they want to stay.

INTRODUCTION: In high sacrectomy, it is difficult to secure the lateral surgical margin and prevent severe postoperative complications. In this report, we present our unique surgical procedure using transanal total mesorectal excision for locally recurrent rectal cancer. TECHNIQUE: A 49-year-old woman was diagnosed with locally rerecurrent rectal cancer, which was located at the height of the S3 vertebra by preoperative imaging, and posterior pelvic exenteration concomitant with high sacrectomy below the S2 vertebra was planned. A multiaccess transperineal platform was placed to secure the lateral surgical margin using transperineal minimally invasive surgery during the perineal and sacral side procedure. Transperineal minimally invasive surgery has several clinical benefits over the conventional approach. For the perineal approach, a 2-team laparoscopic approach was performed. This surgical intervention with laparoscopic perineal assistance contributed to the completion of the dissection of the planned lateral surgical margin, such as the distal piriformis muscles and the sacrotuberous and sacrospinous ligaments, which are the most difficult areas to access in the lithotomy position. Regarding the sacral approach, it facilitated the dissection of the dorsal space of the sacrum; therefore, only a 7-cm transverse skin incision was required during sacrectomy. Small skin incisions and minimal dissection may reduce surgical site infections. RESULTS: The operative time was 933 minutes, with 80 mL of blood loss. There were no major complications, and pathologically confirmed curative resection was achieved. CONCLUSIONS: Our new technique utilizing transanal total mesorectum excision is feasible to secure the lateral surgical margin with minimal skin incision and dissection and may prevent severe postoperative complications.

INTRODUCTION: It has been considered difficult to achieve en bloc resection in cases of locally advanced rectal cancer with lateral pelvic sidewall invasion. The present study demonstrates a novel surgical procedure for these tumors. TECHNIQUE: There are 3 avascular planes of the retroperitoneum in the pelvic sidewall. Two visceral pelvic fasciae, namely the ureterohypogastric fascia and umbilical prevesical fascia, and the parietal pelvic fascia can be identified. In addition, the key structures of these fasciae, the ureter, umbilical artery, and external iliac vessels, can be identified transperitoneally before any dissection. Thus, these 3 avascular planes can be dissected without resorting to dissection of the retrorectal space. The key steps to this technique are: 1) after dissection from the side opposite to the site of tumor invasion to the dorsal side of the rectum, the avascular planes of the retroperitoneum among the 3 above-mentioned fasciae are dissected; and 2) the retrorectal space and pelvic sidewall space are connected by sharp dissection. RESULTS: Recognizing the 3 above-mentioned fasciae enables the dissection of the avascular planes of the pelvic sidewall, which helps to achieve en bloc dissection in cases of locally advanced rectal cancer with lateral pelvic sidewall invasion. CONCLUSION: The pelvic sidewall could be divided into 3 areas based on the visceral pelvic fasciae, which has helped to achieve en bloc dissection in cases of locally advanced rectal cancer with lateral pelvic sidewall invasion.

PURPOSE: Data on long-term outcomes of familial adenomatous polyposis (FAP) are unclear in Japan because a nationwide registry system is lacking. We assessed overall survival, incidence of neoplasms, fecal incontinence, and postoperative follow-up status of patients with FAP treated surgically in our hospital. METHODS: In total, 154 patients with FAP who underwent radical surgery from 1981 to 2017 in our department were available for the questionnaire. Sixty-five patients, 36 of whom were followed at our hospital, were assessed using clinical records and the questionnaire. RESULTS: The median follow-up time was 187 months (interquartile range, 93.5-296 months). The median age at surgery was 36 years (range, 12-69 years). The 5-, 10-, 15-, and 20-year overall survival rate was 100%, 98%, 95%, and 89%, respectively. All five deaths were caused by diseases other than colorectal cancer. FAP-related neoplasms comprised 23 colorectal cancers, five duodenal cancers, three gastric cancers, five thyroid cancers, two ileal pouch cancers, and nine desmoid tumors. The incidence of desmoid tumors was significantly associated with the operation date. The duration from radical surgery to neoplasm onset significantly differed by neoplasm type. Forty-five of 54 patients (excluding those who died or underwent ileostomy) developed fecal incontinence (median Wexner score of 8). Surgical procedures involving hand-sewn sutures with rectal mucosal stripping were significantly associated with fecal incontinence and the Wexner score. Fifty-eight of the 60 surviving patients underwent follow-up examinations. CONCLUSION: Overall survival was favorable. Fecal incontinence depended on the surgical procedures. Most patients continued to receive follow-up examinations. TRIAL REGISTRATION: No. 3112 by Institutional Review Board of Hyogo College of Medicine.

Colorectal cancer is a major public health concern in Japan. While early-stage colorectal adenocarcinoma treatment entails radical resection of the primary tumor, the importance of perioperative treatment is growing as physicians seek to further improve treatment outcomes. For anal squamous cell carcinoma, definitive chemoradiotherapy is superior to radical surgery in terms of improved patient quality of life. The Colorectal Cancer Study Group of the Japanese Clinical Oncology Group was established in 2001 and has worked to provide answers to common clinical questions and improve treatment outcomes for colorectal and anal cancers through 15 large-scale prospective clinical trials. Here, we discuss the current state of perioperative treatment for early-stage colon, rectal and anal cancers in Japan and approaches taken by the Colorectal Cancer Study Group/the Japanese Clinical Oncology Group to improve treatment outcomes for these cancers.
