e22040 Background: Introduction of independent prognostic markers may play a significant role in future treatment of early stage colorectal cancer (CRC). CEA is still the only recommended (ASCO and EGTM) serological marker in CRC. However, Tissue Inhibitor of Metallo Proteinases-1 (TIMP-1), which is a glycoprotein that acts as an inhibitor of most of the active matrix metalloproteinases, has previously been shown to carry independent prognostic information in patients with primary CRC. The purpose of the present study was to assess the combination of preoperative serum CEA and plasma TIMP-1as prognostic markers in patients undergoing resection for primary CRC. Methods: In the present prospective study serum and plasma samples were collected before surgery from 422 patients with primary CRC stage I-III. CEA was determined in serum by a commercial assay and TIMP-1 was determined in plasma using a thoroughly validated, in-house ELISA. Time to recurrence or death of CRC was registered and the association to serum CEA and plasma TIMP-1 levels were studied in a Cox multivariate model including age, gender, disease stage and tumor location. Hazard ratios and 95% confidence intervals (HR (95%CI)) for disease free survival (DFS) were calculated. Results: An event was recorded in 186 patients, 75 had local recurrence, 103 had a distant metastases (28 of these patients had both local recurrence and distant metastases) and 36 died from their cancer without a registered recurrence. Scoring CEA and TIMP-1 as continuous variables on a logarithmic scale (base 2), both serum CEA and plasma TIMP-1 were statistically significant in a multivariable analysis with HR=1.12 (1.03–1.21) and HR=1.51 (1.12–2.04), respectively. Additional calculations of low CEA plus low TIMP-1, high CEA plus low TIMP-1, low CEA plus high TIMP-1 and high CEA plus high TIMP-1 showed that high plasma TIMP-1 levels carried prominent information of poor prognosis independent of CEA. Conclusions: Preoperative serum CEA and plasma TIMP-1 levels were independent predictors of disease free survival for patients with primary CRC. Combination of the two proteins showed that TIMP-1 was a prominent predictor of poor DFS independent of CEA. [Table: see text]

Introduction: Serum carcinoembryonic (CEA) antigen is used as a diagnostic screening tool during follow-up in colorectal cancer patients. However, it remains unclear whether preoperative serum CEA is a reliable marker in the follow-up to predict recurrence. The aim of the study is to determine the value of elevated pre- and postoperative serum carcinoembryonic antigen levels (CEA > 5 µg/L) as an independent prognostic factor for locoregional and distant recurrence in patients who underwent curative surgery for colorectal cancer. Methods: This single center retrospective observational cohort study includes patients who underwent curative surgery for colorectal cancer between 2005 and 2015 and had pre- and postoperative serum CEA measurements. Five-year disease-free survival and multivariate Cox regression analyses were performed to adjust for confounding factors. Results: Preoperative serum CEA level was measured in 2093 patients with colorectal cancer. No significant association was found between an elevated preoperative serum CEA and locoregional recurrence (adjusted hazard ratio (HR) 1.29 (95% confidence interval (CI) 0.91, 1.84; P=0.26)). However, a significant association was found between an elevated preoperative serum CEA and systemic recurrence (adjusted HR 1.58 (95% CI 1.25, 2.00; P<0.01)]. The five-year disease-free survival was lower in patients with elevated preoperative serum CEA levels ( P<0.01). Postoperative serum CEA level was the most sensitive for hepatic metastases during follow-up (73.3%). Conclusions: The preoperative serum CEA level is an independent prognostic factor for systemic metastasis after curative surgery for colorectal cancer in patients with stage I–III disease. The level is the most sensitive for hepatic metastasis compared to metastasis to other anatomic sites.

Abstract Objective To evaluate local recurrence, metastases, and survival outcomes of `wait and watch’ (WW) strategy and local excision (LE) of tumours, in comparison to the present standard practice of total mesorectal excision (TME) for locally advanced rectal cancers. Data Sources MEDLINE, EMBASE, PubMed databases, and sources of Grey literature. Study Selection Randomised and non-randomised prospective studies, retrospective studies with propensity-score-matched analyses. Data Extraction and Synthesis These were carried out independently by two reviewers. A random-effects methodology was used for meta-analyses. Data was presented keeping with the 27-item PRISMA checklist. Main Outcomes The primary outcomes of interest were local recurrence, distant metastases, disease-free-survival and overall-survival, which were assessed in comparison to those associated with radical surgeries (TME). Results 7 of the 16 studies in the systematic review were included for the quantitative synthesis and meta-analysis. Local recurrence rates were comparable amongst patients in WW group and LE group to those undergoing TME. [Risk ratio (RR) 3.07/1.41; 95% Confidence Interval (CI) 0.86-10.95/0.66-3.01; P = 0.08/P=0.89 respectively]. Rates of distant metastases in the WW group and LE group were comparable to those undergoing TME [RR = 0.71/0.94; 95% CI 0.22-2.30/0.55-1.61; P = 0.56/ P = 0.83 respectively]. The median 3-year disease-free survival among patients undergoing WW, LE procedure, and TME were 88%, 80%, and 78.2% respectively; and the median 3-year overall survival among the three groups were 96%, 93%, and 89.5% respectively. Conclusions and Relevance Organ-preservation strategies appear to be a viable treatment option in the management of rectal-cancers. Further research is warranted to provide stronger levels of evidence on organ-preservation strategies.

SummaryThe aim of the present study was to analyse the preoperative platelet count and the platelet-lymphocyte ratio (PLR) in patients with colorectal cancer (CRC) of different stages and with hepatic metastasis of CRC (mCRC) and to compare these factors as potential prognostic markers. Clinicopathological data of 10 years were collected retrospectively from 336 patients with CRC and 118 patients with mCRC. Both in the CRC and the mCRC group overall survival (OS) was significantly worse in patients who had elevated platelet count (hazard ratio [HR] = 2.2, p < 0.001 and HR = 2.9, p = 0.018, respectively). Multivariate analysis indicated that elevated platelet count was an independent prognostic factor of CRC (HR = 1.7, p = 0.035) and mCRC (HR = 3.1, p = 0.017). Disease-free survival (DFS) was significantly worse in patients with elevated platelet count in the CRC group (HR = 2.0, p = 0.011). In the multivariate analysis the PLR was not a prognostic factor in either of the two cohorts (HR = 0.92, p < 0.001 and HR = 0.89, p = 0.789, respectively). The platelet count is a valuable prognostic marker for the survival in patients both with CRC and mCRC while the PLR is not prognostic in either group.

Background: Incidence and mortality estimates are used to measure the burden of cancer in a population and survival estimates are ideal for evaluating the outcome of cancer control activities. Survival studies evaluate the quality and quantity of life of a group of patients after diagnosing the disease. The patient survival after the diagnosis of cervical cancer is indirectly influenced by socio-economic factors. The present study was carried out with an aim to evaluate the success rate of chemo-radiation followed by brachytherapy to the patients of locally advanced carcinoma (Ca.) cervix in a tertiary care center.Methods: All cases were staged according to the International Federation of Gynaecologists and Oncologists (FIGO) staging system. To illustrate the observed survival of cancer patients Kaplan-Meier curve was plotted. All the patients, except one, completed chemo-radiation and were retrospectively analyzed for the presence of local residual disease, local recurrence, distant metastases, radiation reactions, disease-free survival, and overall survival.Results: There were 22 patients of Carcinoma cervix reported in the radiation oncology department in the year 2018 and 2019. The overall treatment time ranged from 30 days to 178 days, with a median of 63 days. All the patients had a complete response after the treatment. The median follow-up time for all the patients was 15 months. Three patients had a metastatic recurrence and one patient developed distant metastases as well as local recurrence. Overall survival rate was 100% while the disease-free survival rate was 81.82%.Conclusions: The response to chemo-radiation in the treatment of locally advanced Carcinoma cervix is comparable to historic data and is well tolerated.

Objective: Laparoscopic colorectal cancer (CRC) surgery has increasingly become the standard of care world-wide. However, the availability within the rural Western Australian setting remains heterogenous and the long term outcome is largely unknown. This study reviews our experience and 5 year outcomes in laparoscopic colorectal cancer surgery (CRC) in a major rural surgical unit in Western Australia. Materials and Methods: This is a retrospective study based in Albany Regional Hospital, Western Australia. All patients who underwent elective laparoscopic colorectal surgery for cancer by a single surgeon over a five-year period (2007- 2012) were included. All case records were reviewed. All cases had been discussed in multidisciplinary meeting and recommendations were followed in regards to staging modalities and / or neo-adjuvant and adjuvant treatments. Patients were followed up in the surgical clinic six monthly with serial CEA and a yearly CT Chest, abdomen and pelvis and colonoscopy as per guidelines, thereafter they were discharged for GP follow. The primary outcomes were local recurrence, metastatic disease, five year disease free survival, anastomotic stricture, incisional hernia and small bowel obstruction. Results: Sixty-seven patients were reviewed. Two required conversion to open (3%) and were not considered further. A total of 65 patients were included (30 male, mean age: 69 years). The most common site of tumour was at the ascending colon which comprised of 38% of all cases. The mean operating time was 161 minutes. Five year disease free survival was 97%, no Local recurrence of anastomotic strictures were detected in our study, The overall cancer related mortality was one case out of the 65 cases. Conclusions: Laparoscopic colorectal cancer surgery is safe and feasible in the rural Western Australian setting with comparable 5 year outcomes with international literature. Provided this is performed by appropriately trained general surgeons with suitable case selection.

AbstractResistance to chemotherapy remains the major cause of treatment failure in patients with colorectal cancer (CRC). Here, we identified TRIM25 as an epigenetic regulator of oxaliplatin (OXA) resistance in CRC. The level of TRIM25 in OXA-resistant patients who experienced recurrence during the follow-up period was significantly higher than in those who had no recurrence. Patients with high expression of TRIM25 had a significantly higher recurrence rate and worse disease-free survival than those with low TRIM25 expression. Downregulation of TRIM25 dramatically inhibited, while overexpression of TRIM25 increased, CRC cell survival after OXA treatment. In addition, TRIM25 promoted the stem cell properties of CRC cells both in vitro and in vivo. Importantly, we demonstrated that TRIM25 inhibited the binding of E3 ubiquitin ligase TRAF6 to EZH2, thus stabilizing and upregulating EZH2, and promoting OXA resistance. Our study contributes to a better understanding of OXA resistance and indicates that inhibitors against TRIM25 might be an excellent strategy for CRC management in clinical practice.

Second-generation radiofrequency ablation (RFA) probes and their successors have more power, shorter ablation times, and an increased area of ablation compared with the first-generation probes used before 2000. We examined whether the use of the newer probes has improved the clinical outcome of RFA for hepatic metastases of colorectal cancer at our tertiary cancer center. Of 160 patients who underwent RFA between 1997 and 2003, 52 had metastases confined to the liver: 21 patients underwent 46 ablations with the first-generation probes and 31 patients underwent 58 ablations with the newer probes. The two groups had similar demographic characteristics. At a median follow-up of 26.2 months, patients treated with the newer probes had a longer median disease-free survival (16 months vs 8 months, P < 0.01) and a lower rate of margin recurrence (5.2% vs 17.4%); eight patients had no evidence of disease and one patient was alive with disease. By contrast, of the 46 patients treated with the first-generation probes, 2 patients had no evidence of disease and 1 patient was alive with disease. Newer-generation probes are associated with lower rates of margin recurrence and higher rates of disease-free survival after RFA of hepatic metastases from colorectal cancer.
