Purpose: This study aimed to evaluate and compare the quality of total mesorectal excision (TME) and disease-free and overall survival rates between robotic and laparoscopic surgeries for rectal cancer.Methods: From January 2015 to December 2018, 234 patients underwent curative robotic or laparoscopic surgery for rectal cancer at two centers. Ultimately, 201 patients were enrolled. To control for different demographic factors in the two groups, propensity score matching was used at a 1:1 ratio. Propensity scores were generated with the baseline characteristics, including age, sex, body mass index, American Society of Anesthesiologists score, previous abdominal surgery, tumor location, preoperative chemotherapy, and preoperative radiation. Finally, 134 patients were matched with 67 patients in the robotic surgery group and 67 patients in the laparoscopic surgery group.Results: There was no significant difference in the pathologic stages between the robotic and laparoscopic surgery groups. Distal margin involvement was only observed in the robotic surgery group (1/67, 1.5%). Circumferential resection margin involvement was not different between the robotic surgery and laparoscopic surgery groups (3/67 [4.5%] and 4/67 [6.0%], respectively, P = 1.000). The quality of TME (complete, nearly complete, and incomplete) was similar between the robotic surgery and laparoscopic surgery groups (88.0%, 6.0%, 6.0% and 79.1%, 9.0%, 11.9%, respectively, P = 0.358). The disease-free and overall survival rates were not significantly different between the groups.Conclusion: The quality of TME and disease-free and overall survival rates between the two surgeries were similar. There was no oncologic advantage of robotic surgery for rectal cancer compared to laparoscopic surgery.

Abstract INTRODUCTION Transanal total mesorectal excision (TaTME) for rectal cancer offers a better vision of the dissection planes and facilitates the distal transection of the rectum. The aim of this study was to compare functional outcomes, local recurrence rate y 2-years overall survival and disease free survival rates of TaTME and laparoscopic total mesorectal excision (LPC TME). MATERIAL AND METHODS From December 2016 to October 2018, 50 patients (36 males and 14 females) with low rectal cancer and an age of 67 (55.7-75.2) years underwent TME (20 TaTME and 30 LPCTME). RESULTS Clinical features and quality indicators for rectal cancer surgery were similar in both groups. After a median follow-up of 35 (30-40) months, low anterior resection syndrome rate was 14% (15% vs 13%, p = 0.043), fecal incontinence rate was 8% (15% vs 3%, p = 0.017) and sexual dysfunction was 8% (15% vs 3%, p = 0.017). Systemic recurrence rate was 10% (15% vs 6%, p = 0.377). One patient presented local recurrence 2 years after TATME. 2-years overall survival rate was 98% (95% vs 100%, p = 0.400) and 2-years disease free survival rate was 90 % (85% vs 93%, p = 0.377). CONCLUSION Although 2-years overall survival and disease free survival rates were similar in TaTME and LPC TME group, functional outcomes were worse after TATME in our study.

AbstractBackground:This review evaluates whether brachytherapy can be considered as an alternative to whole breast irradiation (WBI) using criteria such as local recurrence rates, overall survival rates and quality of life (QoL) factors. This is an important issue because of a decline in local recurrence rates, suggesting that some women at very low risk of recurrence may be incurring the negative long-term side effects of WBI without benefitting from a reduction in local recurrence and greater overall survival. As such, the purpose of this literature review is to evaluate whether brachytherapy is a credible alternative to external beam radiation with a particular focus on the impact it has on patient QoL.Methods:The search terms used were devised by using the Population Intervention Comparison Outcome framework, and a literature search was carried out using Boolean connectors and Medical Subject Headings in the PubMed database. The resultant articles were manually assessed for relevance and appraised using the Scottish Intercollegiate Guidelines Network tool. Additional papers were sourced from the citations of articles found using the search strategy. Government guidelines and regulations were also used following a manual search on the National Institute for Health and Care Excellence website. This process resulted in a total of 30 sources being included as part of the review.Results:Three types of brachytherapy were the foundation for the majority of the papers found: interstitial multi-catheter brachytherapy, intra-cavity brachytherapy and permanent seed implantation. The key themes that arose from the literature were that brachytherapy is equivalent to WBI both in terms of 5-year local recurrence rates and overall survival rates at 10–12 years. The findings showed that brachytherapy was superior to WBI for some QoL factors such as being less time-consuming and equal in terms of others such as breast cosmesis. The results did also show that brachytherapy does come with its own local toxicities that could impact upon QoL such as the poor breast cosmesis associated with some brachytherapy techniques.Conclusion:In conclusion, brachytherapy was deemed a safe or acceptable alternative to WBI, but there is a need for further research on the long-term local recurrence rates, survival rates and quality of life issues as the volume of evidence is still significantly smaller for brachytherapy than for WBI. Specifically, there needs to be further investigation as to which patients will benefit from being offered brachytherapy and the influence that factors such as co-morbidities, performance status and patient choice play in these decisions.

The aim of the studywas to summarize data on the role of tumor-associated dendritic cells (DC) in the formation of squamous cell carcinoma microenvironment, their participation in the development of immune inflammatory responses in the tumor stroma and relation to tumor progression.Material and Methods. We analyzed 79 publications available from Pubmed, Google Scholar, Elibrary databases from January 2000 to December 2017.Results. The characteristics of different types of DC, including Langerhans cells (CR), were presented. The different methods of DC identification were described. The information on the presence of DC in squamous cell carcinomas was analyzed. The influence of the tumor on DCs, as well as the relationship between the number and functional characteristics of DCs and invasive/metastatic tumor potentialities was described. The prognostic value of DCs and their effect on disease-free, metastasis-free and overall survival rates were analyzed. The data on the association between DCs and the response to chemoradiotherapy were presented. The analysis of the relationship between the DC characteristics and the development of immuno-inflammatory responses in the tumor microenvironment was carried out.Conclusion. The methodological approaches to the detection of DCs are variable, but the sensitivity of each method, as well as the comparison of different methods for estimating the number and functional characteristics of DCs, have been little studied. There is no data on the relationship between the length of DC dendrites and the parameters of invasive/metastatic tumor potentialities, disease-free, metastasis-free and overall survival rates. Numerous studies indicate the association between the number of DCs and the tumor progression, however these data are contradictory. There is no data about the relationship between the number of DCs and hematogenous metastasis of squamous cell carcinomas. The association of tumor-associated DC with the types of immunoinflammatory responses in the tumor microenvironment has been insufficiently studied.

11041 Background: Postoperative tumor board recommendations for breast cancer are mainly based on patient characteristics and tumor parameters such as size, histologic grade, lymphovascular invasion (LVI), hormone receptor and HER2/neu status. In the era of potential avoidance of axillary surgery in clinically node-negative patients we evaluate the impact of pathologic nodal status for adjuvant treatment decisions. Methods: The postoperative tumor board records of 207 consecutive breast cancer patients over a 1-year period were rediscussed without knowledge of pathologic nodal status. Differences between the two board recommendations for each patient were classified as major (chemo- and/or radiotherapy: present/absent) or minor (different chemotherapeutic protocols) discrepancies. The disease-free and overall survival rates among subgroups with different recommendations were calculated using Adjuvant! Online tool. The binary logistic regression was performed to analyze the impact of factors for prediction the major discrepancy subgroup. Results: The tumor board without information of pathologic nodal status resulted in treatment changes in 72 of the 207 patients studied (34.8%). Major discrepancies were observed in 37 patients (17.9%) leading to a complete shift of postoperative management. Disease-free and overall survival rates were not significantly different due to a balanced over- and undertreatment in this subgroup (21 cases with under-, 16 cases with overtreatment). The major discrepancies were related to LVI (P=0.001), postmenopausal status (P=0.047), and positive hormone receptor status (P=0.17) in the univariate setting. LVI was an independent parameter to predict the subgroup with major discrepancies performing a multivariate analysis (P=0.006; RR=4.5 [95%CI: 1.5–13.4]). Conclusions: The knowledge of pathologic nodal status is important for postoperative chemotherapy and postmastectomy radiotherapy indications. There is a risk for one third of all patients when avoiding axillary surgery to get an adjuvant therapy which differ from the current treatment guidelines. It is mandatory to know the nodal status for breast tumors with LVI. No significant financial relationships to disclose.

Introduction: Primary testicular lymphoma constitutes a rare subgroup among extranodal non-Hodgkin’s lymphomas. Because of its aggressive clinical behaviour due to high grade histological features developing mainly in older population, patients with this disease usually have a poor prognosis. Orchidectomy followed by combination immunochemotherapy is a traditional treatment method with a rather inferior outcome. Aim: In this retrospective survey the authors analysed the clinical presentation, pathological features and treatment results of patients with primary testicular lymphoma diagnosed and treated in their haematology centre between 2000–2012 Method: During this period 334 patients with aggressive non-Hodgkin’s lymphomas were treated, of whom 8 patients (2.39%; age between 23 and 86 years; median, 60 years) underwent semicastration for primary testicular lymphoma (7 patients had diffuse, large B-cell lymphoma and one patient had Burkitt-like lymphoma). According to the Ann Arbor staging system a limited stage I-IIE was diagnosed in 7 patients and advanced stage was found in one patient. All but one patients were treated with rituximab added to CHOP regimen (6 or 8 cycles in every 21 or 28 days), whereas one patient received radiotherapy only. Central nervous system intrathecal prophylaxis was used in one case and no preventive irradiation of the contralateral testis was used. Results: With a median follow-up of 50 months complete remission was observed in 7 patients. However, two patients died (one due to progression and one in remission from pulmonary solid tumour). Complete remission rate proved to be 87.5%, disease-free survival was between 13 and 152 months (median 38 months) and overall survival rates were between 17 and 156 months (median 43 months). The 5-year disease-free and overall survival rates were 37.5 %. Conclusions: The relatively favourable treatment outcome could be mainly explained by the high number of patients with early-stage of the disease, early surgical removal of testicular lymphomas and the use if immunochemotherapy. This therapeutic regimen was effective to prevent localized and distant relapses. Despite omission of regular prophylaxis of the central nervous system, no relapse was detected. Orv.

✓ The authors conducted a retrospective review of the clinical and treatment characteristics and outcomes in 28 pediatric patients with anaplastic ependymoma treated with radiation therapy since the advent of computerized tomography (CT) (1978–1994). Twelve patients received craniospinal irradiation followed by a boost to the primary site, two received whole-brain radiation therapy followed by a boost to the primary site, and the remaining 14 were treated with focal radiation therapy. The mean dose to the primary site was 5486 cGy. With a median follow-up period of 86 months for the 14 surviving patients (range 31–201 months), the median disease-free survival, measured from the date of diagnosis to the time of recurrence after radiation therapy, was 40 months. The median disease-free survival measured from the start of radiation therapy was 32 months. The median overall survival rate has not been reached and the actuarial estimates of overall survival rates at 5 and 10 years were 56% and 38%, respectively. According to univariate analysis, the disease-free survival rate was significantly improved (p < 0.01) in patients who underwent a gross-total resection at diagnosis. Overall survival rates were negatively influenced by treatment with craniospinal and whole-brain irradiation. As calculated by multivariate analysis, increasing dosage to the primary site (p < 0.05), infratentorial location (p < 0.01), and gross-total resections (p < 0.02) resulted in the longest disease-free survival times. All 19 patients in whom treatment failed after radiation therapy suffered a recurrence at the primary site. In addition, one of these patients experienced subarachnoid dissemination. Radiation treatment recommendations for patients with ependymoma have been based on the tumor's location, perceived risk for dissemination, and malignant propensity. The significance of anaplastic histological classification is controversial. Differences in the disease-free and overall survival rates have been demonstrated between ependymomas and anaplastic ependymomas treated in the pre—CT era. The results of this study show that there is no benefit from craniospinal irradiation in this group of patients.
