Abdel-Gawad W, Zaghloul A, Fakhr I, Sakr M, Shabana A, Lotayef M, Mansour O. Evaluation of the frequency and pattern of local recurrence following intersphincteric resection for ultra-low rectal cancer. J Egypt Natl Canc Inst 2014; 26:87-92. [PMID: 24841159 DOI: 10.1016/j.jnci.2014.02.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2013] [Revised: 12/26/2013] [Accepted: 02/03/2014] [Indexed: 01/26/2023] Open
Abstract
INTRODUCTION Abdomino-perineal resection has been the standard treatment for rectal tumors located ≤5cm from the anal verge. Recently, intersphincteric resection became a valid option which preserves the bowel continuity with better functional outcome. AIM Is to evaluate the oncological and functional outcome alongside the associated surgical morbidity in patients with T1-3 rectal cancer, who underwent intersphincteric resection (ISR). PATIENTS & METHODS Between the years 2006 and 2011, 55 patients with invasive rectal adenocarcinoma, T1-3 lesions, located 2-5cm from the anal verge underwent ISR with total mesorectal excision. When inevitable, complete. ISR was performed, otherwise partial ISR was done. All T3 patients underwent total meso-rectal excision (TME) while some had lateral lymph node dissection (LND) with concomitant pelvic autonomic nerve preservation (PANP). RESULTS Among the 55 patients, 21 (38.1%) patients were T1-2 and 34 (61.9%) patients were T3. The tumor location range was 0-5cm from the anal verge (median 2.3cm). Partial or complete ISR was done for 35 (63.6%) and 20 (36.4%), respectively. Patients were followed for a median of 1.5 years (range 1-4.6 years). The 3 year local recurrence and distant metastasis free rates were 85.2% and 85.6%, respectively. All the 3 local recurrences occurred in T3 patients group, and had positive circumferential resection margins. Overall 3-year disease-free survival was 82.6%; while the overall 3-year survival was 88.7%. CONCLUSION Intersphincteric resection with TME does not affect the local recurrence or overall survival rate in early rectal cancer T1-2 & 3, with preservation of bowel continuity and better life quality.

Local recurrence rates after radiofrequency ablation or resection of colorectal liver metastases. Analysis of the European Organisation for Research and Treatment of Cancer #40004 and #40983. Eur J Cancer 2014; 50:912-9. [PMID: 24411080 DOI: 10.1016/j.ejca.2013.12.008] [Citation(s) in RCA: 136] [Impact Index Per Article: 13.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2013] [Revised: 12/07/2013] [Accepted: 12/10/2013] [Indexed: 01/03/2023]
Abstract
AIM The aim of this study is to describe local tumour control after radiofrequency ablation (RFA) and surgical resection (RES) of colorectal liver metastases (CLM) in two independent European Organisations for Research and Treatment of Cancer (EORTC) studies. BACKGROUND Only 10-20% of patients with newly diagnosed CLM are eligible for curative RES. RFA has found a place in daily practice for unresectable CLM. There are no prospective trials comparing RFA to RES for resectable CLM. METHODS The CLOCC trial randomised 119 patients with unresectable CLM between RFA (±RES)+adjuvant FOLFOX (±bevacizumab) versus FOLFOX (±bevacizumab) alone. The EPOC trial randomised 364 patients with resectable CLM between RES±perioperative FOLFOX. We describe the local control of resected patients with lesions ≤4 cm in the perioperative chemotherapy arm of the EPOC trial (N=81) and the RFA arm of the CLOCC trial (N=55). RESULTS Local recurrence (LR) rate for RES was 7.4% per patient and 5.5% per lesion. LR rate for RFA was 14.5% per patient and 6.0% per lesion. When lesion size was limited to 30 mm, LR rate for RFA lesions was 2.9% per lesion. Non-local hepatic recurrences were more often observed in RFA patients than in RES patients, 30.9% and 22.3% respectively. Patients receiving RFA had a more advanced disease. CONCLUSIONS LR rate after RFA for lesions with a limited size is low. The local control per lesion does not appear to differ greatly between RFA and surgical resection. This study supports the local control of RFA in patients with limited liver metastases. Future studies should evaluate in which patients RFA could be an equal alternative to liver resection.

Abstract
BACKGROUND Ductal carcinoma in situ (DCIS) often accompanies invasive ductal carcinoma (IDC). The presence of co-existing DCIS is postulated to present as a less aggressive phenotype than IDC alone. PATIENTS AND METHODS Patients diagnosed with hormone receptor-positive breast cancer receiving mastectomy were evaluated. Only patients without adjuvant radio- and chemotherapy were included to decrease treatment bias on local recurrence (LR). RESULTS Of 2239 breast cancer patients, 198 fulfilled the inclusion criteria. The overall LR rate was 11.6%. Tumor stage (p = 0.002), nodal status (pN2 vs. pN0, p = 0.023) and pure IDC compared with IDC-DCIS (p = 0.029) were multivariate independent factors for increased LR risk. Patients with IDC-DCIS were significantly younger (p < 0.001), had smaller tumors (p = 0.001), less lymph node involvement (p = 0.012). The LR rate was significantly increased in patients with pure IDC (p = 0.012). The time to distant metastases was decreased in patients with pure IDC compared with that observed in patients with IDC-DCIS (log rank = 0.030). CONCLUSION Invasive ductal carcinoma accompanied by DCIS is associated with lower LR. The prognostic value of co-existing DCIS in the adjuvant decision-making process may be considered a new independent prognostic marker. This finding needs further studies to evaluate its usefulness in premenopausal women.

Abstract
We report a case of local recurrence of cancer after rectal endoscopic submucosal dissection (ESD). A 52-year-old male underwent a curative resection with ESD for rectal intramucosal cancer. Seventy-four months after ESD, surveillance colonoscopy showed an elevated lesion on the ESD scar, suspicious of a recurrence. The patient subsequently underwent a low anterior resection (intersphincteric) with lymph node dissection. Pathology revealed a well-differentiated adenocarcinoma, similar to the ESD specimen. We suspected that the local recurrence was caused by implantation of tumor cells during the ESD, due to surgical manipulation performed with the tumor in an exposed setting for a long period of time.

Abstract
BACKGROUND It has been shown that intraluminal washout (WO) can prevent local recurrence (LR) of rectal cancer. This meta-analysis was to evaluate the association of rectal WO and the risk of LR after anterior resection in patients with rectal cancer. METHODS The relevant studies were identified by a search of the MEDLINE, Embase, Wiley Online Library, and Cochrane Oral Health Group Specialized Register with no restrictions on October 18, 2013, and these studies were included in a systematic review and meta-analysis. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in fixed effects model. RESULTS A total of nine studies were included in our study, yielding a total of 5519 patients, and pooled ORs for overall LR in corresponding subgroups were calculated. Rectal WO was associated with a lower risk for LR (240/4176, 5.75% versus 9.75%, 131/1343, OR = 0.53, 95% CI = 0.42-0.68, and P < 0.00001) in patients with anterior resection, having total mesorectal excisions (234/3942, 5.93% versus 9.34%, 97/1039, OR = 0.59, 95% CI = 0.46-0.75, and P < 0.00001), and after radical resection (RR; 122/2665, 4.99% versus 8.90%, 74/831, OR = 0.56, 95% CI = 0.41-0.78, and P = 0.0005), with an overall LR rate of 6.72% (371/5519). But, the stability of RRs is not high in the total mesorectal excisions or RR subgroup by sensitivity analysis. CONCLUSIONS The use of rectal WO decreases risks of LR in patients after anterior resection of cancer.

Abstract
Elevated levels of circulating cell-free Epstein-Barr virus (EBV) DNA have been detected in plasma and serum samples from nasopharyngeal cancer (NPC) patients by quantitative real time PCR (qPCR) test. This qPCR test for circulating EBV DNA was found to be useful in the clinical management of NPC patients. For instance, EBV DNA qPCR test has good sensitivity and specificity in the detection of NPC at disease onset. Increase of the viral DNA load was found in NPC patients at late stages of disease. High EBV DNA load at disease onset or detectable viral load post-treatment was associated with poor survival or frequent relapse in NPC patients. Residual EBV DNA load after primary treatment could be a useful indicator to justify adjuvant chemotherapy. The qPCR test might also be applied to define a poor prognostic group in patients at early stage (I/II) for implementing concurrent chemo-radiotherapy (chemo-RT) to improve patients' outcome. The test is also useful to monitor distant metastases or response to radiotherapy, chemo-RT or surgery. Supplementary tests, however, are needed to pick up EBV negative WHO type I NPC and test improvement is needed to increase sensitivity in detecting stage I disease and local recurrence.

Abstract
The incidence of anastomotic recurrence after curative resection of colorectal cancer is relatively low compared to that of other types of recurrence, such as hepatic, lung and local recurrence. However, almost all cases of anastomotic recurrence of colorectal cancer occur within 3 years after surgery. We experienced a rare case of anastomotic recurrence in whom colonoscopy revealed no signs of recurrence 3 years after surgery; however, anastomotic recurrence was detected over 5 years after surgery. A 60-year-old female with a history of surgery for cancer of the cecum in her forties underwent sigmoidectomy and right colectomy with D3 lymph node dissection for both stage IIA sigmoid colon cancer and stage IIA transverse colon cancer. Computed tomography and colonoscopy revealed no signs of recurrence 3 years after surgery; however, 5 years and 4 months after surgery, colonoscopy demonstrated surrounding flaring and swelling in the anastomotic area of the sigmoid colon, and a biopsy revealed an adenocarcinoma. Under the diagnosis of anastomotic recurrence over 5 years after surgery, lower anterior resection was performed. The patient has exhibited no other signs of recurrence in the 2 years since the last operation.

Abstract
BACKGROUND Osteosarcoma is a high grade malignant, osteoid forming, primary bone tumor affecting the metaphysis of long bones. Local recurrence (LR) in osteosarcomas is a sinister. Theoretically, a high tumor volume at the time of presentation will limit surgical margins, involve vital neurovascular bundles and show poor response to chemotherapy thereby causing high rates of amputations (as against limb salvage surgery) and should be associated with poor survival rates. This study evaluated objectively if high tumor volume is a significant predictor of local recurrence (LR) in operated cases of osteosarcomas. MATERIALS AND METHODS Operated cases of osteosarcoma (presenting to the Orthopedic outpatient or the Medical Oncology outpatient between January 1, 2004 and January 1, 2011 were included in the study. Their preoperative clinical data and investigations along with the operative notes were traced from the medical/departmental records. Details of chemotherapy received in the neo-adjuvant and postoperative periods were noted. Besides, all demographic data were also noted. Tumor volume was calculated using the available magnetic resonance images using the formula: ([π/6] × length × width × depth). Post data extraction, patients were divided in two groups, Groups I (without LR) and Group II (with LR). RESULTS A total of 95 cases of biopsy proven osteosarcomas were identified. Of which 64 were male and 31 females. There were 15 (15.8%) local recurrences. 71% (57/80) patients without LR fell in the age group of 10-20 years, while 66% (10/15) patients with LR were in the age group of 10-20 years. Limb salvage surgery was done in 81.05% (77/95) patients while a total of 18 patients underwent amputation. Of the 80 cases in Group I (without LR), 40 (50%) patients had tumor volume >200 c.c., 30 patients (37.5%) had tumor volume between 50 and 200 c.c. while only 10 patients had tumor volumes <50 c.c. This was in contrast to the tumor volume noted in Group II (with LR) of 15 patients where 8 patients had a tumor volume between 50 and 200 c.c., five had bigger tumor volumes of >200 c.c. and only two patients were smaller in size, with a tumor volume <50 c.c. The mean tumor volume in the group without LR was 406.74 ± 771.67 c.c. as compared with 195.77 ± 226.8 c.c. in the group with local recurrence. Using Mann-Whitney test, the difference between the two groups was found to be statistically insignificant (P = 1.403). CONCLUSIONS We conclude that high tumor volume is not a significant predictor of LR in osteosarcomas thus patients with high tumor masses should not be denied limb salvage. However, we recommend that the decision on attempting limb salvage should not only be based on the tumor volume alone.

Can computer navigation-assisted surgery reduce the risk of an intralesional margin and reduce the rate of local recurrence in patients with a tumour of the pelvis or sacrum?

Abstract
We hypothesised that the use of computer navigation-assisted surgery for pelvic and sacral tumours would reduce the risk of an intralesional margin. We reviewed 31 patients (18 men and 13 women) with a mean age of 52.9 years (13.5 to 77.2) in whom computer navigation-assisted surgery had been carried out for a bone tumour of the pelvis or sacrum. There were 23 primary malignant bone tumours, four metastatic tumours and four locally advanced primary tumours of the rectum. The registration error when using computer navigation was < 1 mm in each case. There were no complications related to the navigation, which allowed the preservation of sacral nerve roots (n = 13), resection of otherwise inoperable disease (n = 4) and the avoidance of hindquarter amputation (n = 3). The intralesional resection rate for primary tumours of the pelvis and sacrum was 8.7% (n = 2): clear bone resection margins were achieved in all cases. At a mean follow-up of 13.1 months (3 to 34) three patients (13%) had developed a local recurrence. The mean time alive from diagnosis was 16.8 months (4 to 48). Computer navigation-assisted surgery is safe and has reduced our intralesional resection rate for primary tumours of the pelvis and sacrum. We recommend this technique as being worthy of further consideration for this group of patients.

Abstract
We evaluated the risk of late relapse and further outcome in patients with soft-tissue sarcomas who were alive and event-free more than five years after initial treatment. From our database we identified 1912 patients with these pathologies treated between 1980 and 2006. Of these 1912 patients, 603 were alive and event-free more than five years after initial treatment and we retrospectively reviewed them. The mean age of this group was 48 years (4 to 94) and 340 were men. The mean follow-up was 106 months (60 to 336). Of the original cohort, 582 (97%) were alive at final follow-up. The disease-specific survival was 96.4% (95% confidence interval (CI) 94.4 to 98.3) at ten years and 92.9% (95% CI 89 to 96.8) at 15 years. The rate of late relapse was 6.3% (38 of 603). The ten- and 15-year event-free rates were 93.2% (95% CI 90.8 to 95.7) and 86.1% (95% CI 80.2 to 92.1), respectively. Multivariate analysis showed that tumour size and tumour grade remained independent predictors of events. In spite of further treatment, 19 of the 38 patients died of sarcoma. The three- and five-year survival rates after the late relapse were 56.2% (95% CI 39.5 to 73.3) and 43.2% (95% CI 24.7 to 61.7), respectively, with a median survival time of 46 months. Patients with soft-tissue sarcoma, especially if large, require long-term follow-up, especially as they have moderate potential to have their disease controlled.

Abstract
BACKGROUND AND OBJECTIVE Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). PATIENTS AND METHODS The study included six patients with TC and cervical lymphadenopathies evaluated before initial thyroid surgery and 10 patients followed up after TC surgery with cervical lumps discovered. FNA was performed in all 16 masses. Results of cyto-FNA, Tg-FNA and of the combined tests were compared to the final diagnosis of each lesion. RESULTS Among 10 lesions proven to be malignant at surgery, cyto-FNA, Tg-FNA and the combination of both allowed for adequate diagnosis in 7, 9, and 10 cases respectively. Among 6 lesions considered to be benign, cyto-FNA was able to confirm diagnosis in 4, was non-diagnostic in one, and was falsely negative in the remaining case, while Tg-FNA was below the established cut-off value (to consider malignancy) in all cases. CONCLUSIONS In patients with TC and suspect cervical masses, Tg-FNA improved the diagnostic yield of cyto-FNA alone, thus warranting its routine recommendation when FNA is performed. However, universal standardization of the technique and definition of valid cut-off thyroglobulin values (depending on the immunoassay used) above which the lesion should be considered to be malignant are still pending.

Abstract
INTRODUCTION The optimal width of microscopic margin and the use of adjuvant therapy after a positive margin for hepatic resection for colorectal liver metastasis (CRCLM) has not been conclusively determined. The aim of the current study is to evaluate the influence of width of surgical margin and adjunctive therapy upon disease free and overall survival. METHODS All patients undergoing hepatectomy for CRCLM from 1997 to 2012 were identified from a prospectively maintained, IRB approved database. Patients were divided into four subgroups based on the parenchymal margin: positive, <0.1 cm, 0.1 cm-1 cm, and >1 cm. RESULTS A total of 373 patients were included for analysis with a median follow up of 26 months (range 9-103 months) and a median overall survival of 53 months. The resection margin was positive (26 patients median OS 24 months), <0.1 cm (48 patients median OS 36 mon), 0.1 cm-1 cm (82 patients median OS 44 months), and >1 cm (217 patients median OS 64 months). The most common adjunctive therapy was chemotherapy, hepatic arterial therapy, or local. Patients with positive margins also had the shortest disease free survival (DFS), 16 months. The DFS was similar amongst the other margin groups (<0.1 cm: 21 months, 0.1-1 cm: 22 months, >1 cm 25 months). Hepatectomy margin independently influenced survival (p = 0.017) and disease free survival (p = 0.034). Patients with negative margins has similar overall recurrence rates (p = 0.36) and survival rates (p = 0.89). CONCLUSIONS A positive surgical margin indicates a worse overall biology of disease for patients undergoing hepatectomy for CRCLM, and appropriate multi-disciplinary therapy should be considered in this high risk patient population. Marginal width if a complete resection has been achieved does not adversely effect overall surgical in patients with CRCLM.

Abstract
Local recurrence (LR) has an adverse impact on rectal cancer treatment. Neoadjuvant chemoradiotherapy (nCRT) is increasingly administered to patients with progressive cancers to improve the prognosis. However, LR still remains a problem and its pattern can alter. Correspondingly, new risk factors have emerged in the context of nCRT in addition to the traditional risk factors in patients receiving non-neoadjuvant therapies. These risk factors are decisive when reviewing treatment options. This review aims to elucidate the distinctive risk factors related to LR of rectal cancers in patients receiving nCRT and to clarify their clinical significance. A search was conducted on PubMed to identify original studies investigating patients with rectal cancer receiving nCRT. Outcomes of interest, especially potential risk factors for LR in patients with nCRT, were then analyzed. The clinical importance of these risk factors is discussed. Remnant cancer cells, lymph-nodes and tumor response were found to be major risk factors. Remnant cancer cells decide the status of resection margins. Local excision following nCRT is promising in ypT0-1N0M0 cases. Dissection of lateral lymph nodes should be considered in advanced low-lying cancers. Although better tumor response resulted in a relatively lower recurrence rate, the evidence available is insufficient to justify a non-operative approach in clinical complete responders to nCRT. LR cannot be totally avoided by current multidisciplinary approaches. The related risk factors resulting from nCRT should be considered when making decisions regarding treatment selection.

Abstract
BACKGROUND The relationship between surgical margin and local recurrence (LR) in osteosarcoma patients with poor responses to chemotherapy is unclear. Moreover, the incidences of LR according to three different resection planes (bone, soft tissue, and perineurovascular) are not commonly known. METHODS We evaluated the incidence of LR in three areas. To assess whether there is a role of surgical margin on LR in patients resistant to preoperative chemotherapy, we designed a case (35 patients with LR) and control (70 patients without LR) study. Controls were matched for age, location, initial tumor volume, and tumor volume change during preoperative chemotherapy. RESULTS LR occurred at the soft tissues in 18 cases (51.4%), at the perineurovascular tissues in 11 cases (31.4%), and at the bones in six cases (17.2%). The proportion of inadequate perineurovascular margin was higher in the case group than in the control group (p = 0.01). Within case-control group (105 patients), a correlation between each margin status and LR at corresponding area was found in the bone (p < 0.001) and perineurovascular area (p = 0.001). CONCLUSIONS LR is most common in soft tissues. In patients showing similar unfavorable responses to chemotherapy, the losses of perineurovascular fat plane on preoperative magnetic resonance imaging may be a valuable finding in predicting LR.

Abstract
Malignant melanoma of the conjunctiva is a rare tumour of middle and old age. It is seen predominantly in whites, and is rare in those of pigmented ethnicity. Its clinical presentation varies, and making a clinical diagnosis may be difficult. The tumour is potentially fatal and displays a high rate of recurrence, which can be attributed to delay in diagnosis, as well as inadequate surgical approach. The literature on this melanoma is scanty, even in the West, particularly regarding the precise surgical technique. We report a case of malignant melanoma of the conjunctiva which showed a local recurrence one year after the primary surgery. However, there was no evidence of distant metastasis on either occasion. This case highlights the need for care in making a diagnosis, meticulous attention to the surgical technique, and careful follow-up to detect further disease activity.

Local recurrence following breast-conserving treatment in women aged 40 years or younger: trends in risk and the impact on prognosis in a population-based cohort of 1143 patients. Eur J Cancer 2013; 49:3093-101. [PMID: 23800672 DOI: 10.1016/j.ejca.2013.05.030] [Citation(s) in RCA: 76] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2013] [Revised: 05/24/2013] [Accepted: 05/29/2013] [Indexed: 11/29/2022]
Abstract
AIM To evaluate trends in the risk of local recurrences after breast-conserving treatment (BCT) and to examine the impact of local recurrence (LR) on distant relapse-free survival in a large, population-based cohort of women aged ≤40 years with early-stage breast cancer. METHODS All women (n=1143) aged ≤40 years with early-stage (pT1-2/cT1-2, N0-2, M0) breast cancer who underwent BCT in the south of the Netherlands between 1988 and 2010 were included. BCT consisted of local excision of the tumour followed by irradiation of the breast. RESULTS After a median follow-up of 8.5 (0.1-24.6)years, 176 patients had developed an isolated LR. The 5-year LR-rate for the subgroups treated in the periods 1988-1998, 1999-2005 and 2006-2010 were 9.8% (95% confidence interval (CI) 7.1-12.5), 5.9% (95% CI 3.2-8.6) and 3.3% (95% CI 0.6-6.0), respectively (p=0.006). In a multivariate analysis, adjuvant systemic treatment was associated with a reduced risk of LR of almost 60% (hazard ratio (HR) 0.42; 95%CI 0.28-0.60; p<0.0001). Patients who experienced an early isolated LR (≤5 years after BCT) had a worse distant relapse-free survival compared to patients without an early LR (HR 1.83; 95% CI 1.27-2.64; p=0.001). Late local recurrences did not negatively affect distant relapse-free survival (HR 1.24; 95% CI 0.74-2.08; p=0.407). CONCLUSION Local control after BCT improved significantly over time and appeared to be closely related to the increased use and effectiveness of systemic therapy. These recent results underline the safety of BCT for young women with early-stage breast cancer.

Abstract
OBJECTIVES Due to concerns about implantation of malignant cells during surgery for rectal cancer, traditionally, intraoperative rectal washout (IORW) has been performed to prevent local recurrence. But with the advent of laparoscopic surgery, many surgeons have abandoned this practice. The aim of this study was to assess current practice among colorectal surgeons in the UK. METHODS A 10-item questionnaire was sent by email to 452 consultant surgeons, who were members of the Association of Coloproctology of Great Britain & Ireland, and had previously agreed to participate in research projects. RESULTS The mean age of the 149 responders (n = 149, 33.0%) was 49.2 years. The mean number of years in independent practice was 12.1, and the mean number of rectal cancer cases performed per year was 20.3 and 20.6, in the years 2010 and 2011 respectively. 74.3% of the responders believed that there is an advantage in performing IORWs in rectal cancer resections. Of the 71.8% of all responders who performed laparoscopic rectal cancer resections, 54.8% routinely performed IORWs during laparoscopic resections. However, 87.2% of all responders performed IORWs in open resections for rectal cancer, and 79.2% had routinely performed IORWs before the advent of laparoscopic rectal cancer surgery. CONCLUSIONS Most colorectal surgeons believe that there is an advantage in performing IORWs. Although, most surgeons would routinely perform IORWs in open resections, they do not routinely perform these in laparoscopic resections.

Abstract
BACKGROUND The status of the surgical margins of lumpectomy is one of the most important determinants of local recurrence in breast cancer. Systematically practicing cavity margin resection is debated but may avoid surgical re-excision and allow the diagnosis of multifocality. METHODS This multicentric retrospective study included 294 patients who underwent conservative management of breast cancer with 2-4 systematic cavity shavings. Clinico-biological characteristics of the patients were collected in order to establish whether surgical management was modified by systematic cavity shaving. Local recurrence rate with a long-term follow up of minimum 4 years was evaluated. RESULTS Cavity shaving avoided the need for re-excision in 25% of cases and helped in the diagnosis of multifocality in 8% of cases. Resection volume was not associated with usefulness of the cavity shaving. No predictive factor of positive cavity shaving was found. The rate of local recurrence was 3.7% and appeared in a median time of 3 years and 8 month. Only one quarter of the patients with local recurrence had initially positive lumpectomy margins but negative cavity shaving. DISCUSSION Systematic cavity shaving can change surgical management of conservative treatment. No specific target population for useful cavity shaving was found, such that we recommend utilising it systematically.

Abstract
Although rare, synovial sarcoma (SS) is one of the most common soft tissue sarcomas affecting young adults. To investigate potential tumor markers related to synovial sarcoma prognosis, we carried out a single-institution retrospective analysis of 103 patients diagnosed with SS between 1980 and 2009. Clinical outcome data were obtained from medical records, and archived tissue samples were used to evaluate the relationship between progression-free survival (PFS) and several prognostic factors, including tumor expression of FGFR3 and FGFR4. No associations were found between PFS and gender, body mass index, tumor site, SS18-SSX translocation, or FGFR4 expression. As seen in previous studies, age at diagnosis (<35, 63% versus ≥35 years, 31% 10-year PFS; P = .033), histologic subtype (biphasic, 75% versus monophasic 34% 10-year PFS; P = .034), and tumor size (≤5 cm, 70% versus >5 cm, 22% 10-year PFS; P < .0001) were associated with PFS in SS patients. In addition, in a subset of patients with available archived tumor samples taken prior to chemotherapy or radiation (n = 34), higher FGFR3 expression was associated with improved PFS (P = .030). To the best of our knowledge, this is the largest study of SS to date to suggest a potential clinical role for FGFR3. While small numbers make this investigation somewhat exploratory, the findings merit future investigation on a larger scale.

Abstract
BACKGROUND We evaluated the clinical implications of human epidermal growth factor receptor (HER)-2 overexpression after adjuvant radiotherapy (RT) for ductal carcinoma in situ (DCIS). METHODS We reviewed 215 patients with DCIS who underwent breast-conserving surgery followed by RT. The association between HER-2 overexpression and ipsilateral breast tumor recurrence (IBTR) was evaluated. RESULTS HER-2 overexpression was associated with comedo-type architecture, high nuclear grade, and negative hormonal receptors. The median follow-up duration was 75 months. Sixteen patients experienced IBTR; seven as DCIS recurrence and nine as invasive recurrence. The IBTR rate was 11.4% at 10 years. There was no significant difference in IBTR according to HER-2 expression (P = 0.1764), neither in invasive nor DCIS recurrence. Time to recurrence was shorter in HER-2 positive tumors (P = 0.0697). CONCLUSION Adjuvant RT seems to counteract the negative effect of HER-2 overexpression in DCIS, while time to recurrence was relatively shorter.

Abstract
Hepatocellular carcinoma (HCC) is the second commonest cancer in Taiwan. The national surveillance program can detect HCC in its early stages, and various curative modalities (including surgical resection, orthotopic liver transplantation, and local ablation) are employed for the treatment of small HCC. Local ablation therapies are currently advocated for early-stage HCC that is unresectable because of co-morbidities, the need to preserve liver function, or refusal of resection. Among the various local ablation therapies, the most commonly used modalities include percutaneous ethanol injection and radiofrequency ablation (RFA); percutaneous acetic acid injection and microwave ablation are used less often. RFA is more commonly employed than other local ablative modalities in Taiwan because the technique is highly effective, minimally invasive, and requires fewer sessions. RFA is therefore advocated in Taiwan as the first-line curative therapy for unresectable HCC or even for resectable HCC. However, current RFA procedures are less effective against tumors that are in high-risk or difficult-to-ablate locations, are poorly visualized on ultrasonography (US), or are large. Recent advancements in RFA in Taiwan can resolve these issues by the creation of artificial ascites or pleural effusion, application of real-time virtual US assistance, use of combination therapy before RFA, or use of switching RF controllers with multiple electrodes. This review article provides updates on the clinical outcomes and advances in local ablative modalities (mostly RFA) for HCC in Taiwan.

Abstract
PURPOSE In case of ipsilateral breast tumour recurrence (IBTR), radical mastectomy represents the treatment option frequently proposed. A second conservative treatment (2ndCT) has been proposed using either lumpectomy alone or associated with a re-irradiation of the tumor bed. However, in both clinical situations, the proof level of such therapeutic approaches remains low, based on cased-series or retrospective studies (level C). MATERIAL AND METHODS In order to assess the different strategies of local treatment proposed in case of IBTR, a PubMed literature review was performed using the following keywords: breast cancer, ipsilateral recurrence, mastectomy, radiation therapy, brachytherapy. Four different salvage options were analyzed: (a) salvage mastectomy alone; (b) salvage mastectomy with postoperative re-irradiation; (c) 2ndCT with surgery alone; (d) 2ndCT with re-irradiation. RESULTS The rate of second local recurrence is about 10% [3-32%], about 25% [7-36%] and about 10% [2-26%], after salvage mastectomy, salvage lumpectomy alone or combined with a re-irradiation of the tumor bed respectively. However, the 5-year overall survival rates after salvage mastectomy and 2ndCT seem to be equivalent (≈75%) mainly influenced by distant metastatic progression. CONCLUSION In terms of Evidence Based Medicine, different options can be discussed such as Phase III or II randomized trials comparing salvage mastectomy versus 2ndCT, retrospective studies based on a matched-pair analysis or observatory studies. Those study designs need to be carefully analyzed to be able to propose new treatment options for women who experience an IBCR.

Abstract
AIM: To identify factors associated with prognosis of hepatocellular carcinoma (HCC) after initial therapy.
METHODS: A total of 377 HCC patients who were newly treated at Katsushika Medical Center, Japan from January 2000 to December 2009 and followed up for > 2 years, or died during follow-up, were enrolled. The factors related to survival were first analyzed in 377 patients with HCC tumor stage T1-T4 using multivariate Cox proportional hazards regression analysis. A similar analysis was performed in 282 patients with tumor stage T1-T3. Additionally, factors associated with the period between initial and subsequent therapy were examined in 144 patients who did not show local recurrence. Finally, 214 HCC stage T1-T3 patients who died during the observation period were classified into four groups according to their alcohol consumption and postprandial glucose levels, and differences in their causes of death were examined.
RESULTS: On multivariate Cox proportional hazards regression analysis, the following were significantly associated with survival: underlying liver disease stage [non-cirrhosis/Child-Pugh A vs B/C, hazard ratio (HR): 0.603, 95% CI: 0.417-0.874, P = 0.0079], HCC stage (T1/T2 vs T3/T4, HR: 0.447, 95% CI: 0.347-0.576, P < 0.0001), and mean postprandial plasma glucose after initial therapy (< 200 vs≥ 200 mg/dL, HR: 0.181, 95% CI: 0.067-0.488, P = 0.0008). In T1-T3 patients, uninterrupted alcohol consumption after initial therapy (no vs yes, HR: 0.641, 95% CI: 0.469-0.877, P = 0.0055) was significant in addition to underlying liver disease stage (non-cirrhosis/Child-Pugh A vs B/C, HR: 0649, 95% CI: 0.476-0.885, P = 0.0068), HCC stage (T1 vs T2/T3, HR: 0.788, 95% CI: 0.653-0.945, P = 0.0108), and mean postprandial plasma glucose after initial therapy (< 200 mg/dL vs≥ 200 mg/dL, HR: 0.502, 95% CI: 0.337-0.747, P = 0.0005). In patients without local recurrence, time from initial to subsequent therapy for newly emerging HCC was significantly longer in the “postprandial glucose within 200 mg/dL group” than the “postprandial glucose > 200 mg/dL group” (log-rank test, P < 0.05), whereas there was no difference in the period between the “non-alcohol group” (patients who did not drink regularly or those who could reduce their daily consumption to < 20 g) and the “continuation group” (drinkers who continued to drink > 20 g daily). Of 214 T1-T3 patients who died during the observation period, death caused by other than HCC progression was significantly more frequent in “group AL” (patients in the continuation and postprandial glucose within 200 mg/dL groups) than “group N” (patients in the non-alcohol and postprandial glucose within 200 mg/dL groups) (P = 0.0016).
CONCLUSION: This study found that abstinence from habitual alcohol consumption and intensive care for diabetes mellitus were related to improved prognosis in HCC patients.

Abstract
Although the incidence of local recurrence after curative resection of rectal cancer has decreased due to the understanding of the anatomy of pelvic structures and the adoption of total mesorectal excision, local recurrence in the pelvis still remains a significant and troublesome complication. While surgery for recurrent rectal cancer may offer a chance for a cure, conservative management, including radiation and chemotherapy, remain widely accepted courses of treatment. Recent improvement in imaging modalities, perioperative care, and surgical techniques, including bone resection and wound coverage, have allowed for reductions in operative mortality, though postoperative morbidity still remains high. In this review, the techniques, including surgical approaches, employed for management of locally recurrent rectal cancer are highlighted.

Abstract
AIM: To investigate the patterns and decisive prognostic factors for local recurrence of rectal cancer treated with a multidisciplinary team (MDT) modality.
METHODS: Ninety patients with local recurrence were studied, out of 1079 consecutive rectal cancer patients who underwent curative surgery from 1999 to 2007. For each patient, the recurrence pattern was assessed by specialist radiologists from the MDT using imaging, and the treatment strategy was decided after discussion by the MDT. The associations between clinicopathological factors and long-term outcomes were evaluated using both univariate and multivariate analysis.
RESULTS: The recurrence pattern was classified as follows: Twenty-seven (30%) recurrent tumors were evaluated as axial type, 21 (23.3%) were anterior type, 8 (8.9%) were posterior type, and 13 (25.6%) were lateral type. Forty-one patients had tumors that were evaluated as resectable by the MDT and ultimately received surgery, and R0 resection was achieved in 36 (87.8%) of these patients. The recurrence pattern was closely associated with resectability and R0 resection rate (P < 0.001). The recurrence pattern, interval to recurrence, and R0 resection were significantly associated with 5-year survival rate in univariate analysis. Multivariate analysis showed that the R0 resection was the unique independent factor affecting long-term survival.
CONCLUSION: The MDT modality improves patient selection for surgery by enabling accurate classification of the recurrence pattern; R0 resection is the most significant factor affecting long-term survival.

Abstract
AIM: To evaluate the oncological outcomes of transanal local excision and the need for immediate conventional reoperation in the treatment of patients with high risk T1 rectal cancers.
METHODS: Twenty five high risk T1 rectal cancers treated by transanal local excision at the Guangdong General Hospital were analyzed retrospectively. Twelve patients received transanal local excision and 13 patients underwent subsequent immediate surgical rescue after transanal local excision within 4 wk. Differences in the local recurrence rates and 5-year overall survival rates between the two groups were analyzed. The prognostic value of immediate conventional reoperation for high risk T1 rectal cancers was also evaluated.
RESULTS: The median follow-up period was 62 mo. The local recurrence rates after transanal local excision for high risk T1 rectal cancer were 50%. By immediate conventional reoperation, the local recurrence rates were significantly reduced to 7.7%. The difference between these two groups was statistically significant (P = 0.030). Kaplan-Meier survival analysis showed a trend for decreased 5-year overall survival rates for patients treated by transanal local excision compared with immediate conventional reoperation (63% vs 89%).
CONCLUSION: Transanal local excision cannot be considered sufficient treatment for patients with high risk T1 rectal cancers. Immediate conventional reoperation should be performed if the pathology of the local excision is high risk.

Abstract
Purpose We evaluated the effect of local recurrence (LR) and regional recurrence (RR) on distant metastasis and survival in patients treated with breast conservation therapy (BCT). Methods We analyzed 907 patients who were treated for invasive breast cancer between 1993 and 2006. With 53 months of follow-up, 28 patients (3.1%) developed LR in the breast and 12 patients (1.3%) developed RR before distant metastasis. LR and RR were separated into four patterns to determine the prognostic relevance of recurrence site and time to recurrence: LR within 3 years (early LR), LR after 3 years (late LR), RR within 3 years (early RR), and RR after 3 years (late RR). Results Early LR (hazard ratio [HR], 4.76; p=0.003) and early RR (HR, 18.16; p<0.001) were independent predictors of distant metastasis. In terms of overall survival, early LR (HR, 5.24; p=0.002), and early RR (HR, 18.80; p<0.001) were significantly related with poor survival. Patients with late LR/RR had a similar favorable prognosis compared with patients who never experienced LR/RR. Conclusion The result suggests that time to LR/RR following BCT is a significant predictor developing a distant metastasis and surviving.

[PMID: 22007278 PMCID: PMC3192216 DOI: 10.4240/wjgs.v3.i8.113] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2011] [Revised: 08/10/2011] [Accepted: 08/16/2011] [Indexed: 02/06/2023] Open
Abstract
AIM: To evaluate patients with proximal rectal cancer (PRC) (> 6 cm up to 12 cm) and distal rectal cancer (DRC) (0 to 6 cm from the anal verge).
METHODS: Two hundred and eighteen patients (120 male, 98 female, median age 58 years, range 19-88 years) comprised 100 with PRC and 118 with DRC. The proportion of T1, T2 vs T3, T4 stage cancers was similar in both groups (PRC: T1+T2 = 29%; T3+T4 = 71% and DRC: T1+T2 = -31%; T3+T4 = 69%). All patients had cancer confined to the rectum - those with synchronous distant metastasis were excluded. Surgical resection was with curative intent with or without pre-operative chemoradiation (c-RT). Follow-up was for a median of 35 mo (range: 12 to 126 mo). End points were: 30 d mortality, complications of operation, microscopic tumour- free margins, resection with a tumour-free circumferential margin (CRM) of 1 to 2 mm and > 2 mm, local recurrence, survival and the permanent stoma rate.
RESULTS: Overall 30-d mortality was 6% (12): PRC 7 % and DRC 4%. Postoperative complications occurred in 14% with PRC compared with 21.5% with DRC, urinary retention was the complication most frequently reported (PRC 2% vs DRC 9%, P = 0.04). Twelve percent with PRC compared with 37% with DRC were subjected to preoperative c-RT (P = 0.03). A tumour-free CRM of 1 to 2 mm and > 2 mm was reported in 93% and 82% with PRC and 88% and 75% with DRC respectively (PRC vs DRC, P > 0.05). However, local recurrence was 5% for PRC vs 11% for DRC (P < 0.001). Three and five years survival was 65.6% and 60.2% for PRC vs 67% and 64.3% for DRC respectively. No patient with PRC and 23 (20%) with DRC received an abdomino-perineal resection.
CONCLUSION: PRC and DRC differ in the rate of abdomino-perineal resection, post-operative urinary retention and local recurrence. Survival in both groups was similar.

Mulsow J, Winter DC. Sphincter preservation for distal rectal cancer - a goal worth achieving at all costs? World J Gastroenterol 2011; 17:855-61.

Abstract
To assess the merits of currently available treatment options in the management of patients with low rectal cancer, a review of the medical literature pertaining to the operative and non-operative management of low rectal cancer was performed, with particular emphasis on sphincter preservation, oncological outcome, functional outcome, morbidity, quality of life, and patient preference. Low anterior resection (AR) is technically feasible in an increasing proportion of patients with low rectal cancer. The cost of sphincter preservation is the risk of morbidity and poor functional outcome in a significant proportion of patients. Transanal and endoscopic surgery are attractive options in selected patients that can provide satisfactory oncological outcomes while avoiding the morbidity and functional sequelae of open total mesorectal excision. In complete responders to neo-adjuvant chemoradiotherapy, a non-operative approach may prove to be an option. Abdominoperineal excision (APE) imposes a permanent stoma and is associated with significant incidence of perineal morbidity but avoids the risk of poor functional outcome following AR. Quality of life following AR and APE is comparable. Given the choice, most patients will choose AR over APE, however patients following APE positively appraise this option. In striving toward sphincter preservation the challenge is not only to achieve the best possible oncological outcome, but also to ensure that patients with low rectal cancer have realistic and accurate expectations of their treatment choice so that the best possible overall outcome can be obtained by each individual.

Abstract
AIM: To evaluate the quality of life and local recurrence for rectal cancer which under vent posterior pelvic exenteration (PPE) with anal sphincter preservation.
METHODS: Sixty cases with rectal cancer invading female reproductive system underwent PPE with anal sphincter preservation (SP group) or colon stoma (CS group) respectively. Thirty cases with low anterior resection rectal cancer were selected as control group (LAR group).Wexner scoring systems and vectorial manometry were used to compare the quality of life between the SP group and LAR group, and compare the 2-year local recurrence rate and survival rate between the SP group and CS group.
RESULTS: Three months after surgery, the Wexner score of SP group was higher than that of the LAR group (10.1 vs 6.1, P < 0.05), but there were no significant difference in score 1 year after surgery between two groups (P > 0.05), and the results of vectorial manometry between two groups also showed no significant difference (P > 0.05). The local recurrence rate and survival rate were 20% and 83.3% for SP group, 23.3% and 80% for CS group with no significant difference observed (both P > 0.05).
CONCLUSION: The quality of life after posterior pelvic exenteration with anal sphincter preservation could reach the level of low anterior resection, and the local recurrence rate and survival rate were similar with colon stoma operation.

Abstract
AIM: To analyze, retrospectively in a population-based study, the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision (TME).
METHODS: All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection (632 patients) were selected from the Amsterdam Cancer Registry. For patients with recurrent disease, information on treatment of the recurrence was collected from the medical records.
RESULTS: Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients (10%). Thirty-two patients had an isolated local recurrence. Ten of these 32 patients (31%) underwent radical re-resection and experienced the highest survival (three quarters survived for at least 3 years). Eight patients (25%) underwent non-radical surgery (median survival 24 mo), seven patients (22%) were treated with radio- and/or chemotherapy without surgery (median survival 15 mo) and seven patients (22%) only received best supportive care (median survival 5 mo). Distant dissemination occurred in 124 patients (20%) of whom 30 patients also had a local recurrence. The majority (54%) of these patients were treated with radio- and/or chemotherapy without surgery (median survival 15 mo). Twenty-seven percent of these patients only received best supportive care (median survival 6 mo), while 16% underwent surgery for their recurrence. Survival was best in the latter group (median survival 32 mo).
CONCLUSION: Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME, patients can benefit from additional treatment, especially if a radical resection is feasible.

Abstract
AIM: To explore the risk factors for local recurrence of middle and lower rectal carcinoma after curative resection.
METHODS: Specimens of middle and lower rectal carcinoma from 56 patients who received curative resection at the Department of General Surgery of Guangdong Provincial People’s Hospital were studied. A large slice technique was used to detect mesorectal metastasis and evaluate circumferential resection margin status. The relations between clinicopathologic characteristics, mesorectal metastasis and circumferential resection margin status were identified in patients with local recurrence of middle and lower rectal carcinoma.
RESULTS: Local recurrence of middle and lower rectal carcinoma after curative resection occurred in 7 of the 56 patients (12.5%), and was significantly associated with family history (χ2 = 3.929, P = 0.047), high CEA level (χ2 = 4.964, P = 0.026), cancerous perforation (χ2 = 8.503, P = 0.004), tumor differentiation (χ2 = 9.315, P = 0.009) and vessel cancerous emboli (χ2 = 11.879, P = 0.001). In contrast, no significant correlation was found between local recurrence of rectal carcinoma and other variables such as age (χ2 = 0.506, P = 0.477), gender (χ2 = 0.102, χ2 = 0.749), tumor diameter (χ2 = 0.421, P = 0.516), tumor infiltration (χ2 = 5.052, P = 0.168), depth of tumor invasion (χ2 = 4.588, P = 0.101), lymph node metastases (χ2 = 3.688, P = 0.055) and TNM staging system (χ2 = 3.765, P = 0.152). The local recurrence rate of middle and lower rectal carcinoma was 33.3% (4/12) in patients with positive circumferential resection margin and 6.8% (3/44) in those with negative circumferential resection margin. There was a significant difference between the two groups (χ2 = 6.061, P = 0.014). Local recurrence of rectal carcinoma occurred in 6 of 36 patients (16.7%) with mesorectal metastasis, and in 1 of 20 patients (5.0%) without mesorectal metastasis. However, there was no significant difference between the two groups (χ2 = 1.600, P = 0.206).
CONCLUSION: Family history, high CEA level, cancerous perforation, tumor differentiation, vessel cancerous emboli and circumferential resection margin status are the significant risk factors for local recurrence of middle and lower rectal carcinoma after curative resection. Local recurrence may be more frequent in patients with mesorectal metastasis than in patients without mesorectal metastasis.

Abstract
AIM: To evaluate the risk factors for lateral lymph node metastasis in patients with advanced low rectal cancer, in order to make the effective selection of patients who could benefit from lateral lymph node dissection, as well as the relationship of lateral lymph node metastasis with local recurrence and survival of patients with advanced low rectal cancer.
METHODS: A total of 96 consecutive patients who underwent curative surgery with lateral pelvic lymphadenectomy for advanced lower rectal cancer were retrospectively analyzed. The relation of lateral lymph node metastasis with clinicopathologic characteristics, local recurrence and survival of patients was identified.
RESULTS: Lateral lymph node metastasis was observed in 14.6% (14/96) of patients with advanced low rectal cancer. Lateral lymph node metastasis was detected in 10 (25.0%) of 40 patients with tumor diameter ≥ 5 cm and in 4 (7.1%) of 56 patients with tumor diameter < 5 cm. The difference between the two groups was statistically significant (χ2 = 5.973, P = 0.015). Lateral lymph node metastasis was more frequent in patients with 4/4 diameter of tumor infiltration (7 of 10 cases, 70.0%), compared with patients with 3/4, 2/4 and 1/4 diameter of tumor infiltration (3 of 25 cases, 12.0%; 3 of 45 cases, 6.7%; 1 of 16 cases, 6.3%) (χ2 = 27.944, P = 0.0001). The lateral lymph node metastasis rate was 30.0% (9 of 30 cases), 9.1% (4 of 44 cases) and 4.5% (1 of 22 cases) for poorly, moderately and well-differentiated carcinoma, respectively. The difference between the three groups was statistically significant (χ2 = 8.569, P = 0.014). Local recurrence was 18.8% (18 of 96 cases), 64.3% (9 of 14 cases), and 11.0% (9 of 82 cases) in patients with advanced low rectal cancer, in those with and without lateral lymph node metastasis, respectively. The difference between the two groups was statistically significant (χ2 = 22.308, P = 0.0001). Kaplan-Meier survival analysis showed significant improvements in median survival (80.9 ± 2.1 m, 95% CI: 76.7-85.1 m vs 38 ± 6.7 m, 95% CI: 24.8-51.2 m) of patients without lateral lymph node metastasis compared with those with lateral lymph node metastasis (log-rank, P = 0.0001).
CONCLUSION: Tumor diameter, infiltration and differentiation are significant risk factors for lateral lymph node metastasis. Lateral pelvic lymphadenectomy should be performed following surgery for patients with tumor diameter ≥ 5 cm. Lateral lymph node metastasis is an important predictor for local recurrence and survival in patients with advanced low rectal cancer.

Abstract
Surgical treatment is still the first choice of management for patients with rectal cancer, but the results were unsatisfied. The difficulties in treatment of rectal cancer are high local recurrence, poor postoperative life quality and low long term survival. First of all, reduction of local recurrence should be our goal and introduction of total mesorectal excision (TME) has significantly improved the outcomes following the curative resection hence the local recurrence rate has reduced to less than 10% and 5-year survival rate has been achieved to 78%. Meanwhile, the sphincter preservation resection has been increased to 70% and become the first choice of procedures in rectal cancer surgery. On the other hand, postoperative genitourinary function has also been improved significantly, so the postoperative quality of life in patients with rectal cancer is now much better than before. Application of neoadjuvant chemoradiation has further improved the surgical and oncological results in patients with locally advanced low rectal cancer (T3 and T4 stage) when combined with TME technique. Advances of systemic therapy with new chemotherapeutic agents have been proved to further improve disease-free survival and overall survival in patients with stage Ⅲ colorectal cancer. In general, treatment for patients with rectal cancer has entered into a multidisciplinary treatment era, and the outcomes of the patients with rectal cancer may be further improved effectively upon a new basis.

Abstract
Inflammatory myofibroblastic tumors (IMTs) or inflammatory pseudotumors (IPs) have been extensively discussed in the literature. They are usually found in the lung and upper respiratory tract. However, reporting of cases involving the biliopancreatic region has increased over recent years. Immunohistochemical study of these lesions limited to the pancreatic head or distal bile duct seems to be compatible with those observed in a new entity called autoimmune pancreatitis, but usually intense fibrotic reaction (zonation) predominates producing a mass. When this condition is limited to the pancreatic head, the common bile duct might be involved by the inflammatory process and jaundice may occur often resembling adenocarcinoma of the pancreas. We have previously reported a case of IMT arising from the bile duct associated with autoimmune pancreatitis which is an extremely rare entity. Four years after Kaush-Whipple resection, radiological examination on routine follow-up revealed a tumor mass, suggesting local recurrence. Ultrasound-guided FNA confirmed our suspicious diagnosis. This present case, as others, suggests that persistent follow-up is necessary in order to prevent irreversible liver damage at this specific location.

Abstract
AIM: To clarify the importance of complete treatment by PEIT.
METHODS: A total of 140 previously untreated cases of HCC were enrolled in this study from 1988 to 2002. The inclusion criteria were: a solitary tumor less than 4 cm in diameter or multiple tumors, fewer than four in number and less than 3 cm in diameter, without extrahepatic metastasis or vessel invasion. As general principles for the treatment of HCC, the patients underwent transcatheter arterial chemoembolization (TACE) prior to PEIT. After the initial treatment of the patients, ultrasonography and computed tomography were performed, and measurement of serum levels of α-fetoprotein (AFP) was determined. When tumor recurrences were detected, PEIT and/or TACE were repeated whenever the hepatic functional reserve of the patient permitted. We then analyzed the variables that could influence prognosis, including tumor size and number, the serum levels of AFP, the parameters of hepatic function (albumin, bilirubin, ALT, hepaplastin test, platelet number, and indocyanine green retention at 15 min [ICG-R15]), combined therapy with TACE, distant recurrence, and local recurrence.
RESULTS: Univariate analysis identified the ICG test, serum levels of AFP and albumin, tumor size and number, and local recurrence, but not distant recurrence, as significant prognostic variables. In multivariate analysis using those five parameters, the ICG test, tumor size, tumor number, and local recurrence were identified as significant prognostic factors. In both univariate and multivariate analyses, the relative risk for the ICG test was the highest, followed by local recurrence.
CONCLUSION: We found that local recurrence is an independent prognostic factor of HCC, indicating that achieving complete treatment for HCC on first treatment is important for improving the prognosis of patients with HCC.

Abstract
We report a case of a 77-year-old female with a local recurrence of cancer after right hemicolectomy which infiltrated the pancreatic head affording pancrea-toduodenectomy, who developed 3 years later recurrent tumor masses localized in the mesentery of the jejunum and in the lower pole of the left kidney. Partial nephrectomy and a segment resection of the small bowel were performed. Histological examination of both specimens revealed a necrotic metastasis of the primary carcinoma of the colon. Although intraluminal implantation of colon cancer cells in the renal pelvic mucosa from ureteric metastasis has been described, metastasis of a colorectal cancer in the kidney parenchyma is extremely rare and can be treated in an organ preserving manner. A complex pattern of colon cancer recurrence with unusual and rare sites of metastasis is reported.
