    The performance of an improved intraoperative gamma-probe for radioassisted oncological surgery is presented and discussed. The probe is based on a square array of four 5x5 mm sup 2 coplanar CdTe room temperature semiconductor detectors and each detector has an independent read out electronic chain, allowing an original handling of the signal. Therefore, the search for gamma-emission hot points may be carried out in two different, independent ways: (1) Finding out the position of the probe corresponding to the maximum value of the total counting rate, on the basis of a trial and error procedure (typical for the conventional probe; (2) Finding out the position of the probe where both the differences between the counting rate performed by orthogonal, adjacent halves of the array vanish (differential method). This makes the new probe sensitive to the bidimensional gradient of the gamma-ray flux, measured on the scanned plane. Furthermore, the algebraic sign of the difference indicates in which direction the prob...

    Full Text Available Robotic surgery for the management of gynecologic cancers allows for minimally invasive surgical removal of cancer-bearing organs and tissues using sophisticated surgeon-manipulated, robotic surgical instrumentation. Early on, gynecologic oncologists recognized that minimally invasive surgery was associated with less surgical morbidity and that it shortened postoperative recovery. Now, robotic surgery represents an effective alternative to conventional laparotomy. Since its widespread adoption, minimally invasive surgery has become an option not only for the morbidly obese but for women with gynecologic malignancy where conventional laparotomy has been associated with significant morbidity. As such, this paper considers indications for robotic surgery, reflects on outcomes from initial robotic surgical outcomes data, reviews cost efficacy and implications in surgical training, and discusses new roles for robotic surgery in gynecologic cancer management.

    IMPORTANCE Large patient cohorts are necessary to validate the efficacy of transoral robotic surgery (TORS) in the management of head and neck cancer. OBJECTIVES To review oncologic outcomes of TORS from a large multi-institutional collaboration and to identify predictors of disease recurrence and disease-specific mortality. DESIGN, SETTING, AND PARTICIPANTS A retrospective review of records from 410 patients undergoing TORS for laryngeal and pharyngeal cancers from January 1, 2007, through December 31, 2012, was performed. Pertinent data were obtained from 11 participating medical institutions. INTERVENTIONS Select patients received radiation therapy and/or chemotherapy before or after TORS. MAIN OUTCOMES AND MEASURES Locoregional control, disease-specific survival, and overall survival were calculated. We used Kaplan-Meier survival analysis with log-rank testing to evaluate individual variable association with these outcomes, followed by multivariate analysis with Cox proportional hazards regression modeling to identify independent predictors. RESULTS Of the 410 patients treated with TORS in this study, 364 (88.8%) had oropharyngeal cancer. Of these 364 patients, information about post-operative adjuvant therapy was known about 338: 106 (31.3) received radiation therapy alone, and 72 (21.3%) received radiation therapy with concurrent chemotherapy. Neck dissection was performed in 323 patients (78.8%). Mean follow-up time was 20 months. Local, regional, and distant recurrence occurred in 18 (4.4%), 15 (3.7%), and 10 (2.4%) of 410 patients, respectively. Seventeen (4.1%) died of disease, and 13 (3.2%) died of other causes. The 2-year locoregional control rate was 91.8% (95% CI, 87.6%-94.7%), disease-specific survival 94.5% (95% CI, 90.6%-96.8%), and overall survival 91% (95% CI, 86.5%-94.0%). Multivariate analysis identified improved survival among women (P = .05) and for patients with tumors arising in tonsil (P = .01). Smoking was associated with worse overall

    The objective of this article was to review the published scientific literature pertaining to robotic surgery and its applications in gynecologic malignancies and to summarize the impact of robotic surgery on the field of gynecologic oncology. Summarizing data from different gynecologic disease-sites, robotic-assisted surgery is safe, feasible, and demonstrates equivalent histopathologic and oncologic outcomes. In general, benefits to robotic surgery include decreased blood loss, fewer perioperative complications and decreased length of hospital stay. Disadvantages include accessibility to robot surgical systems, decreased haptic sensation and fixed cost as well as cost of disposable equipment. As robotic surgery becomes readily available it will be imperative to develop standardized training modalities. Further research is needed to validate the role of robotic surgery in the treatment of gynecologic malignancies.

    To describe our experience using Minimally Invasive Surgery (MIS) techniques in tertiary center with specific oncological pediatric surgery unit. Retrospective review of patients undergoing MIS techniques in pediatric oncology surgery unit between January 2011 and December 2014. MIS procedures were considered made by both techniques such as laparoscopy and thoracoscopy with both diagnostic and therapeutic intent. 4 procedures were diagnostic and the rest were therapeutic: During the study, 56 procedures were performed by MIS. By type of technique, 13 were thoracoscopic (7 metastasectomies, 6 thoracic masses) and 43 laparoscopic (3 hepatic masses, 3 pancreatic masses 7 abdominal masses, 2 ovarian masses, 2 typhlitis 1 splenic mass and 25 oophorectomy for ovarian cryopreservation). In 5 cases (2 thoracic masses 1 pancreatic mass abdominal masses) conversion to open surgery to complete the procedure (2 for caution in the absence of vascular control bleeding 1 and 2 for lack of space) was necessary. In all cases safety principles of oncological surgery were respected. Providing an adecuate selection of patiens, MIS techniques are safe, reproducible and fulfill the objectives of quality of cancer surgery.

    Full Text Available SUMMARY: The Father of Maxillofacial Surgery is General Surgery and not Oral Surgery, as it may seem from a clinical point of view. General Surgery was the precursor of the specialty of Maxillofacial Surgery since the era of the Hippocratics and up to the end of the 18th century and the begining of the 19th century, having as pioneers eminent general surgeons, such as Heister, von Graefe, C. Langenbeck, Syme, Dupuytren,Roux, Chassaignak, Hulihen, Mott, Billroth, B. Langen -beck, Kocher, Macewen, Albert, Broca, and others.The range of action of the a forementioned surgeons included mostly (in 80% of the cases surgical procedures in the maxillofacial area, mainly in the fields of Traumatology (facial fractures, Osteoplasty, reconstructive surgery (cleft lip and cleft palate operations,and the treatment of tumors.In the present article the historical elements connected with the roots of Oncologic Surgery in the maxillofacial area are outlined, an activity developed by the general surgeons of these eras, which are at the same time the pioneers of modern Maxillofacial Surgery.

    Objective: To report oncological cases (excluding those related to breast cancer) for which radioguided surgery has been used in combination with the Radioguided Occult Lesion Localization technique. Introduction: Radioguided surgery enables a surgeon to identify lesions or tissues that have been preoperatively marked with radioactive substances. The Radioguided Occult Lesion Localization technique has been widely used to identify the sentinel lymph node and occult lesions in patients with breast cancer. However, few studies have reported the use of this technique for non-breast cancer pathologies. Methodology: In all cases, injection of Technetium-99m sulfur colloid was performed, directly inside or near by the suspicious lesion, guided by ultrasound or computed tomography, up to 36 hours prior to the surgical procedure. Intraoperative lesion detection was carried out using a gamma-probe. Results: We report five oncology cases in which preoperative markings of the lesions were carried out using the Radioguided Occult Lesion Localization technique. The patients presented with the following: recurrence of renal cell carcinoma, cervical recurrence of papillary carcinoma of the thyroid, recurrence of retroperitoneal sarcoma, lesions of the popliteal fossa, and recurrence of rhabdomyosarcoma of a thigh. In each case, the lesions that were marked preoperatively were ultimately successfully excised. Conclusions: Radioguided surgery has proven to be a safe and effective alternative for the management of oncology patients. The Radioguided Occult Lesion Localization technique can be useful in selected cases where suspect lesions may be difficult to identify intraoperatively, due to their dimensions or anatomical location. The procedure allows for more conservative excisions and reduces the surgery-related morbidity. (author)

  14. Stromal targets for fluorescent-guided oncologic surgery

    Full Text Available Pre-operative imaging techniques are essential for tumor detection and diagnosis, but offer limited help during surgery. Recently the applicability of imaging during oncologic surgery has been recognized, using near infrared fluorescent dyes conjugated to targeting antibodies, peptides or other vehicles. Image-guided oncologic surgery (IGOS assists the surgeon to distinguish tumor from normal tissue during operation, and can aid in recognizing vital structures. IGOS relies on an optimized combination of a dedicated fluorescent camera system and specific probes for targeting.IGOS probes for clinical use are not widely available yet, but numerous pre-clinical studies have been published and clinical trials are being established or prepared. Most of the investigated probes are based on antibodies or peptides against proteins on the membranes of malignant cells, whereas others are directed against stromal cells. Targeting stroma cells for IGOS has several advantages. Besides the high stromal content in more aggressive tumor types, the stroma is often primarily located at the periphery/invasive front of the tumor, which makes stromal targets particularly suited for imaging purposes. Moreover, because stroma up-regulation is a physiological reaction, most proteins to be targeted on these cells are ‘universal’ and not derived from a specific genetic variation, as is the case with many upregulated proteins on malignant cancer cells.

    A small percentage of pediatric solid cancers arise as a result of clearly identified inherited predisposition syndromes and nongenetic lesions. Evidence supports preemptive surgery for children with genetic [multiple endocrine neoplasia type 2 (MEN2), familial adenomatous polyposis syndrome (FAP), hereditary nonpolyposis colorectal cancer (HNPCC), and hereditary diffuse gastric cancer (HDGC) and nongenetic [thyroglossal duct cysts (TGDC), congenital pulmonary airway malformations (CPAM), alimentary tract duplication cysts (ATDC), and congenital choledochal cysts (CCC)] developmental anomalies. Our aim was to explore the utility of risk reduction surgery to treat and prevent cancer in children. A systematic review of the available peer-reviewed literature on PubMed was performed using a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) search strategy, where possible. Search items included "risk reduction surgery", "hereditary cancer predisposition syndrome", "multiple endocrine neoplasia type 2", "familial adenomatous polyposis", "hereditary nonpolyposis colorectal cancer", "hereditary diffuse gastric cancer", "thyroglossal duct cysts", congenital pulmonary airway malformations", "alimentary tract duplication cysts", "malignant transformation", and "guidelines". We identified 67 articles that met the inclusion criteria describing the indications for prophylactic surgery in surgical oncology. For the genetic predisposition syndromes, 7 studies were related to professional endorsed guidelines, 7 were related to surgery for MEN2, 11 were related to colectomy for FAP, 6 were related to colectomy for HNPCC, and 12 related to gastrectomy for HDGC. Articles for the nongenetic lesions included 5 for techniques related to TGDC resection, 9 for surgery for CPAMs, and 10 for resection of ATDCs. Guidelines and strategies varied significantly especially related to the extent and timing of surgical intervention; the exception was for the timing of

    Robotic surgery represents a new horizon in minimally-invasive urological surgery. This systematic review of the literature and meta-analysis examines the effectiveness of robotic surgery compared with laparoscopic or open surgery for major uro-oncological procedures. 25 articles reported findings from 8 trials of prostatectomy (4 trials) and cystectomy (4 trials) including 1033 participants. Robotic surgery is comparable to laparoscopic or open surgery for oncological outcomes, overall complications, and provides somewhat better functional outcome, when compared to laparoscopic and open surgery.

    Full Text Available A workshop of experts from France, Germany, Italy and the United States took place at Humanitas Research Hospital Milan, Italy, on 10-11 February 2016, to examine techniques for and applications of robotic surgery to thoracic oncology. The main topics of presentation and discussion were: robotic surgery for lung resection; robot-assisted thymectomy; minimally invasive surgery for esophageal cancer; new developments in computer-assisted surgery and medical applications of robots; the challenge of costs; and future clinical research in robotic thoracic surgery. The following article summarizes the main contributions to the workshop. The Workshop consensus was that, since video-assisted thoracoscopic surgery (VATS is becoming the mainstream approach to resectable lung cancer in North America and Europe, robotic surgery for thoracic oncology is likely to be embraced by an increasing numbers of thoracic surgeons, since it has technical advantages over VATS, including intuitive movements, tremor filtration, more degrees of manipulative freedom, motion scaling, and high definition stereoscopic vision. These advantages may make robotic surgery more accessible than VATS to trainees and experienced surgeons, and also lead to expanded indications. However the high costs of robotic surgery and absence of tactile feedback remain obstacles to widespread dissemination. A prospective multicentric randomized trial (NCT02804893 to compare robotic and VATS approaches to stage I and II lung cancer will start shortly.

    Local flaps are a group of surgical procedures that can solve the thoracic closure of large defects after breast cancer surgery with low morbidity. Its use in skin necrosis complications after conservative surgery or skin sparing mastectomies facilitates the initiation of adjuvant treatments and reduces delays in this patient group. This article describes the anatomical basis for the planning of thoracic and abdominal local flaps. Also, the application of these local flaps for closing large defects in the chest and selective flaps for skin coverage by necrosis in breast conserving surgery.

    Laparoscopic rectal surgery continues to be a challenging operation associated to a steep learning curve. Robotic surgical systems have dramatically changed minimally invasive surgery. Three-dimensional, magnified and stable view, articulated instruments, and reduction of physiologic tremors leading to superior dexterity and ergonomics. Therefore, robotic platforms could potentially address limitations of laparoscopic rectal surgery. It was aimed at reviewing current literature on short-term clinical and oncological (pathological) outcomes after robotic rectal cancer surgery in comparison with laparoscopic surgery. A systematic review was performed for the period 2002 to 2014. A total of 1776 patients with rectal cancer underwent minimally invasive robotic treatment in 32 studies. After robotic and laparoscopic approach to oncologic rectal surgery, respectively, mean operating time varied from 192-385 min, and from 158-297 min; mean estimated blood loss was between 33 and 283 mL, and between 127 and 300 mL; mean length of stay varied from 4-10 d; and from 6-15 d. Conversion after robotic rectal surgery varied from 0% to 9.4%, and from 0 to 22% after laparoscopy. There was no difference between robotic (0%-41.3%) and laparoscopic (5.5%-29.3%) surgery regarding morbidity and anastomotic complications (respectively, 0%-13.5%, and 0%-11.1%). Regarding immediate oncologic outcomes, respectively among robotic and laparoscopic cases, positive circumferential margins varied from 0% to 7.5%, and from 0% to 8.8%; the mean number of retrieved lymph nodes was between 10 and 20, and between 11 and 21; and the mean distal resection margin was from 0.8 to 4.7 cm, and from 1.9 to 4.5 cm. Robotic rectal cancer surgery is being undertaken by experienced surgeons. However, the quality of the assembled evidence does not support definite conclusions about most studies variables. Robotic rectal cancer surgery is associated to increased costs and operating time. It also seems to be

    Navigation with fluorescence guidance has emerged in the last decade as a promising strategy to improve the efficacy of oncologic surgery. To achieve routine clinical use, the onus is on the surgical community to objectively assess the value of this technique. This assessment may facilitate both Food and Drug Administration approval of new optical imaging agents and reimbursement for the imaging procedures. It is critical to characterize fluorescence-guided procedural benefits over existing practices and to elucidate both the costs and the safety risks. This report is the result of a meeting of the International Society of Image Guided Surgery (www.isigs.org) on February 6, 2015, in Miami, Florida, and reflects a consensus of the participants' opinions. Our objective was to critically evaluate the imaging platform technology and optical imaging agents and to make recommendations for successful clinical trial development of this highly promising approach in oncologic surgery.

    Ranking systems and comparisons of quality and performance indicators will be of increasing relevance for complex "high-risk" procedures such as esophageal cancer surgery. The identification of evidence-based standards relevant for key performance indicators in esophageal surgery is essential for establishing monitoring systems and furthermore a requirement to enhance treatment quality. In the course of this review, we analyze the key performance indicators case volume, radicality of resection, and postoperative morbidity and mortality, leading to continuous quality improvement. Ranking systems established on this basis will gain increased relevance in highly complex procedures within the national and international comparison and furthermore improve the treatment of patients with esophageal carcinoma.

    Full Text Available Chylous ascites is an uncommon form of ascites characterized by milky-appearing fluid caused by blocked or disrupted lymph flow through chyle-transporting vessels. The most common causes of chylous ascites are therapeutic interventions and trauma. In this report, we present four cases of chylous ascites following robot-assisted surgery for endometrial staging and the treatment strategies that we used. After retroperitoneal lymph node dissection, leaving a drain is very useful in diagnosing chylous ascites and observing its resolution; furthermore, the use of octreotide in conjunction with TPN appears to be an efficient treatment modality for chylous ascites and should be considered before any invasive intervention.

    The effect of postmastectomy radiation therapy (PMRT) on immediately reconstructed abdominal wall-based tissue remains imprecisely defined. We evaluated evidence from all fields involved in care of the breast cancer patient in order to advance a unified recommendation regarding this therapeutic sequence. We performed a MEDLINE and manual reference search to identify studies of PMRT with immediate autologous breast reconstruction. Inclusion criteria required studies to describe patients, flaps, and complication rates. Analyses were based on a random effects model. Surgical and radiation oncology literature was reviewed. Eleven retrospective studies of 337 patients with an average follow-up of 18-60 months (out of 268 patients) were selected for inclusion. Overall rates of fat necrosis, revisional surgery, volume loss, and fibrosis/contracture ranged from 16.9% to 35.4%. One out of 260 patients experienced total flap loss. There was an increased probability of fat necrosis in the irradiated breast (OR = 3.13, 95% CI = 1.42-6.89, P = 0.005) among three studies with non-irradiated controls. Five studies evaluated aesthetics with variable outcomes. There is mixed evidence for the utility of PMRT with immediate autologous abdominal wall breast reconstruction. Further investigation requires prospective studies with collaboration among surgical oncologists, radiation oncologists, and plastic surgeons. © 2014 Wiley Periodicals, Inc.

    Robotic surgical platforms were first developed with telesurgery in mind. Conceptualized by NASA and the military to provide surgical expertise to remote locations, some telesurgical success has been documented, but progress has been held back by communication bandwidth limitations. Telepresence surgery, where the surgeon is in proximity to the patient but is provided with an ergonomic console equipped with three-dimensional vision and autonomous control of wristed laparoscopic surgical instruments and energy sources, has shown efficacy first in cardiac and then urologic cancer surgery. Interest is currently focused on the application of this technology in the field of gynecology, with techniques being described to perform simple hysterectomy, myomectomy, tubal anastomosis, and pelvic reconstruction procedures. This article will review the application of robotic- and computer-assisted surgery in the specialty of gynecologic oncology.

    In pediatric endoscopic surgery, a limited view and lack of tactile sensation restrict the surgeon's abilities. Moreover, in pediatric oncology, it is sometimes difficult to detect and resect tumors due to the adhesion and degeneration of tumors treated with multimodality therapies. We developed an augmented reality (AR) navigation system based on preoperative CT and MRI imaging for use in endoscopic surgery for pediatric tumors. The patients preoperatively underwent either CT or MRI with body surface markers. We used an optical tracking system to register the reconstructed 3D images obtained from the CT and MRI data and body surface markers during surgery. AR visualization was superimposed with the 3D images projected onto captured live images. Six patients underwent surgery using this system. The median age of the patients was 3.5 years. Two of the six patients underwent laparoscopic surgery, two patients underwent thoracoscopic surgery, and two patients underwent laparotomy using this system. The indications for surgery were local recurrence of a Wilms tumor in one case, metastasis of rhabdomyosarcoma in one case, undifferentiated sarcoma in one case, bronchogenic cysts in two cases, and hepatoblastoma in one case. The average tumor size was 22.0±14.2 mm. Four patients were treated with chemotherapy, three patients were treated with radiotherapy before surgery, and four patients underwent reoperation. All six tumors were detected using the AR navigation system and successfully resected without any complications. The AR navigation system is very useful for detecting the tumor location during pediatric surgery, especially for endoscopic surgery. Crown Copyright © 2013. All rights reserved.

    Antibiotic prophylaxis is commonly used in head and neck oncologic surgery, due to the clean-contaminated nature of these procedures. There is a wide variety in the use of prophylactic antibiotics regarding the duration of application and the choice of agent. The purpose of this study was to determine whether short-term or long-term antibiotic prophylaxis has an impact on the development of head and neck surgical wound infection (SWI). Retrospective chart review was carried out in 418 clean-contaminated head and neck surgical oncology cases at our department. More than 50 variables including tumour type and stage, type of surgical treatment, co-morbidities, duration and choice of antibiotic prophylaxis, and the incidence of SWI were analysed. Following descriptive data analysis, Chi square test by Pearson and Fisher's exact test were used for statistical evaluation. Fifty-eight of the 418 patients (13.9 %) developed SWI. Patients with advanced disease and tracheotomy showed a significantly higher rate of SWI than those with early stage disease and without tracheotomy (p = 0.012 and p = 0.00017, respectively). However, there was no significant difference between the SWI rates in the short term and long term treatment groups (14.6 and 13.2 %, respectively; p = 0.689). Diabetes and body weight were not found to be risk factors for SWI. Long-term antibiotic prophylaxis was not associated with a decrease in SWI in the entire cohort of patients undergoing clean-contaminated major head and neck oncologic surgery. Our data confirmed the extent of surgery and tracheotomy as being risk factors for postoperative SWI.

    Full Text Available Purpose To assess the oncologic and functional outcomes of salvage renal surgery following failed primary intervention for RCC. Materials and Methods We performed a retrospective review of patients who underwent surgery for suspected RCC during 2004-2012. We identified 839 patients, 13 of whom required salvage renal surgery. Demographic data was collected for all patients. Intraoperative and postoperative data included ischemic duration, blood loss and perioperative complications. Preoperative and postoperative assessments included abdominal CT or magnetic resonance imaging, chest CT and routine laboratory work. Estimated glomerular filtration rate (eGFR was calculated according to the Modification of Diet in Renal Disease equation. Results The majority (85% of the patients were male, with an average age of 64 years. Ten patients underwent salvage partial nephrectomy while 3 underwent salvage radical nephrectomy. Cryotherapy was the predominant primary failed treatment modality, with 31% of patients undergoing primary open surgery. Pre-operatively, three patients were projected to require permanent post-operative dialysis. In the remaining 10 patients, mean pre- and postoperative serum creatinine and eGFR levels were 1.35 mg/dL and 53.8 mL/min/1.73 m2 compared to 1.43 mg/dL and 46.6 mL/min/1.73 m2, respectively. Mean warm ischemia time in 10 patients was 17.4 min and for all patients, the mean blood loss was 647 mL. The predominant pathological stage was pT1a (8/13; 62%. Negative surgical margins were achieved in all cases. The mean follow-up was 32.9 months (3.5-88 months. Conclusion While salvage renal surgery can be challenging, it is feasible and has adequate surgical, functional and oncological outcomes.

    To describe the development of an enhanced recovery after surgery (ERAS) protocol for people undergoing surgery for head and neck cancer. Service improvement project. Head and neck oncology patients. The programme was developed in a series of structured meetings over a 6-month period. Stakeholders included oral and maxillofacial surgeons, otolaryngologists, anaesthetists, dieticians, physiotherapists, speech and language therapists (SALT) and nursing staff. Based on evidence within current literature and a consensus among the group, an ERAS programme for head and neck surgery patients was formulated. A 12-month study of compliance with the ERAS programme was undertaken from February 2014 to January 2015. The process has resulted in the realisation of a head and neck ERAS programme. Key elements include a patient diary, nutritional optimisation, avoiding tracheostomy when possible, goal-directed fluid therapy intra-operatively and a specific head and neck postoperative pain management protocol. Overall compliance was high. Important areas showed lower levels of compliance - only 55% of people were given an explanation of the ERAS programme preoperatively, 75% took preoperative carbohydrate drinks, 10% had individualised goal-directed fluid therapy, and 7% were mobilised in the first 24 h after surgery. The mean length of hospital stay was 14.55 days (sd 7.48). The ERAS programme developed is now embedded in the care pathway for people undergoing head and neck cancer surgery in our unit. The mean length of hospital stay has reduced since the introduction of the programme. © 2015 John Wiley & Sons Ltd.

    All parts of the gastrointestinal tract are accessible for study using nuclear medicine techniques. It has been studied the effect of esophageal reconstruction surgery, in different periods of time, after surgical procedure. Oncologic patients (19) were evaluated after esophageal reconstruction surgery with gastric (group II-14 patients) or colonic tube (group III - 5 patients) and they were compared with 15 healthy volunteers (group I). Gastric emptying was performed in the same subjects using solid food (egg sandwich) labeled with 99mTc-phytate. In emptying gastric studies, the mean (T1/2) of the patients was much faster than those of the control (p<0.05) when 1/3 distal tube was considered as stomach. However, there was no difference between the T1/2 of group II and group III. It could be concluded that this nuclear medicine method could be useful in the monitoring the surgical reconstruction of the esophagus.

    Full Text Available Laparoscopic surgery for middle and lower rectal cancer remain controversial because anatomical and complex surgical procedures specifically influence oncologic outcomes. This study analyzes the long-term outcomes of laparoscopic versus open surgery for middle and lower rectal cancer.Patients (laparoscopic: n = 129, open: n = 152 who underwent curative resection for middle and lower rectal cancer from 2003 to 2008 participated in the study. The same surgical team performed all operations. The mean follow up time of all patients was 74.3 months.No statistical difference in local recurrence rate (7.8% vs. 7.2%; log-rank = 0.024; P = 0.876 and distant recurrence rate (20.9% vs.16.4%; log-rank = 0.699; P = 0.403 between laparoscopic and open groups were observed within 5 years. The 5-year overall survival rates of the laparoscopic and open groups were 72.9% and 75.7%, respectively; no significant statistical difference was observed between them (log-rank = 0.163; P = 0.686. The 5-year survival rates between groups were not different between stages: Stage I (92.6% vs. 86.7%; log-rank = 0.533; P = 0.465; stage II (75.8% vs. 80.5%; log-rank = 0.212; P = 0.645; and Stage III (63.8% vs. 69.1%, log-rank = 0272;P = 0.602. However, significant statistical difference amongst different stages were observed (log-rank = 1.802; P = 0.003.Laparoscopic and open surgery for middle and lower rectal cancer offer equivalent long-term oncologic outcomes. Laparoscopic surgery is feasible in these patients.

  17. Less stress, more success? Oncological implications of surgery-induced oxidative stress.

    Reactive oxygen species (ROS) possess important cell signalling properties. This contradicts traditional thought which associated ROS activity with cell death. Emerging evidence clearly demonstrates that ROS signalling acts as a key regulator in tumour cell survival and in the cellular processes required for tumour cells to successfully metastasise and proliferate. The discovery of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) family of enzymes in the last decade has unravelled much of the mystery surrounding how ROS are generated. Tumour cells are now known to express Nox enzymes which produce ROS required for cellular signalling. Activation of Nox enzymes occurs via interaction with proinflammatory cytokines and growth factors, all of which are released following surgical trauma. As our understanding of the signalling capabilities of ROS grows, the oncological implications of ROS activity are gradually being revealed. Nox-derived ROS are known to play a central role in each step of the metastatic cascade including invasion, adhesion, angiogenesis and proliferation. This article describes how surgery creates a ROS-rich environment, which facilitates redox signalling, and also examines the role played by Nox enzymes in this process. The authors then explore current knowledge of the oncological implications of surgery-induced redox signalling, and discuss current and future therapeutic strategies targeted at ROS and Nox enzymes in cancer patients.

    Full Text Available Background Today, with improvements in laparoscopy technique, surgery of rectal cancer is performed by laparoscopy. Objectives This study was performed to evaluate oncologic results of open versus laparoscopic surgery of rectal cancer in terms of resection margins, removal of lymph nodes and recurrence rate. Patients and Methods This descriptive-analytic study was performed on 88 patients with middle and lower rectal cancer in the two equivalent groups of laparoscopic and open surgery in Mashhad Ghaem and Omid hospitals during 2011 - 2013. Information including age, sex, number of removed and involved lymph nodes, proximal, distal, and radial margins, tumor stage and location, recurrence and disease-free survival collected in the questionnaire and analyzed using descriptive statistics and frequency distribution tables and t-test. Results Both groups of open and laparoscopic surgery had similar characteristics of age, sex, recurrence and disease-free survival, tumor margins and one-year mortality. The number of removed and involved lymph nodes was higher in the laparoscopic group (5.16 vs. 3.55, respectively, with P < 0.050, and 1.74 vs. 0.59 with P = 0.023, but the ratio of involved lymph nodes to the total number of removed lymph nodes was not different between the two groups (LNR (P = 0.071. Tumor stage was higher in the laparoscopic group and most were in stages II and III (P < 0.001. Conclusions Laparoscopic surgery is an effective technique for safe margin and removing lymph nodes in rectal cancer.

    The present study was designed to compare oncologic outcomes of T2 upper tract urothelial carcinoma patients treated with retroperitoneoscopic nephroureterectomy (RNU) or open radical nephroureterectomy (ONU). T2 upper tract urothelial carcinoma patients were treated with RNU (n = 110) or ONU (n = 118) and followed-up for > 5 years. Demographic and clinical data, including preoperative indexes, intraoperative indexes, and oncological outcomes, were retrospectively compared to determine the efficacy of the 2 procedures. The RNU and ONU groups were statistically similar in age, sex, tumor location, and tumor pathologic grade. The original surgery time required for RNU and ONU was statistically similar, but RNU was associated with a significantly smaller volume of intraoperative estimated blood loss and shorter length of postoperative hospital stay. Follow-up (average: 43.2 months; range, 6-72 months) revealed that the estimated 5-year overall survival rate and the estimated 5-year disease-specific survival rate after RNU was slightly worse than after ONU (66.0% vs. 67.1%, and 80.8% vs. 83.8%, respectively), and the estimated 5-year recurrence-free survival rate and the estimated 5-year intravesical recurrence-free survival rates were slightly better than ONU (79.5% vs. 77.9%, and 68.3% vs. 65.6%, respectively). However, none of these differences were statistically significant. The open surgery strategy and the RNU strategy are equally effective for treating T2 upper tract urothelial carcinoma. However, the RNU procedure is safer, less invasive, and requires a shorter duration of postoperative hospitalized care; thus, RNU is recommended as the preferred strategy.

    The aim of this study was to evaluate the oncologic safety of robot thyroid surgery compared to open thyroid surgery for papillary thyroid carcinoma (PTC). We enrolled 722 patients with PTC who underwent a total thyroidectomy with central compartment node dissection (CCND) from January 2009 to December 2010. These patients were classified into open thyroid surgery (n = 610) or robot thyroid surgery (n = 112) groups. We verified the impact of robot thyroid surgery on clinical recurrence and ablation/control-stimulated thyroglobulin (sTg) levels predictive of non-recurrence using weighted logistic regression models with inverse probability of treatment weighting (IPTW). Age, sex, thyroid weight, extent of CCND, and TNM were significantly different between the two groups (p robot groups (1.5% vs. 2.7%; p = 0.608). The proportion of patients with ablation sTg 0.05). Logistic regression with IPTW using the propensity scores estimated by adjusting all of the parameters demonstrated that robot thyroid surgery did not influence the clinical recurrence (OR; 0.784, 95% CI; 0.150-3.403, p = 0.750), ablation sTg (OR; 0.950, 95% CI; 0.361-2.399, p = 0.914), and control sTg levels (OR; 0.498, 95% CI; 0.190-1.189, p = 0.130). Robot thyroid surgery is comparable to open thyroid surgery with regard to oncologic safety in PTC patients.

    Full Text Available Defects of the perineum may result from ablative procedures of different malignancies. The evolution of more radical excisional surgery techniques resulted in an increase in large defects of the perineum. The perineogenital region per se has many different functions for urination, bowel evacuation, sexuality and reproduction. Up-to-date individual and interdisciplinary surgical treatment concepts are necessary to provide optimum oncological as well as quality of life outcome.Not only the reconstructive method but also the timing of the reconstruction is crucial. In cases of postresectional exposition of e. g. pelvic or femoral vessels or intrapelvic and intra-abdominal organs, simultaneous flap procedure is mandatory. In particular, the reconstructive armamentarium of the plastic surgeon should not only include pedicled, but also free microsurgical flaps so that no compromise in terms of the extent of the oncological resection has to be accepted. For intra-abdominally and/or pelvic tumors of the rectum, the anus or the female reproductive system, which were resected through an abdominally and a sacrally surgical access, simultaneous VRAM flap reconstruction is recommendable. In terms of soft tissue sarcoma of the pelvic / caudal abdomen / proximal thigh region, two-stage reconstructions are possible.This review focuses on the treatment of perineum, genitals and pelvic floor defects after resection of malignant tumors, giving a distinct overview of the different type of defects faced in this region and describing a number of reconstructive techniques, especially VRAM flap and pedicled flaps like ALT flap or free flaps. Finally, this review outlines some considerations concerning timing of the different operative steps.

    Full Text Available Abstract Background Quality of life (QoL measurements are important in evaluating cancer treatment outcomes. Factors other than cancer and its treatment may have significant effects on QoL and affect assessment of treatments. Baseline data from longitudinal studies of women with endometrial or ovarian cancer or adnexal mass determined at surgery to be benign were analyzed to determine the degree to which QoL is affected by baseline differences in demographic variables and health. Methods This study examined the effect of independent variables on domains of the Functional Assessment of Cancer Therapy (FACT-G pre-operatively in gynecologic oncology patients undergoing surgery for pelvic mass suspected to be malignant or endometrial cancer. Patients also completed the Short Form Medical Outcomes Survey (SF-36 questionnaire (a generic health questionnaire that measures physical and mental health. Independent variables were surgical diagnosis (ovarian or endometrial cancer, benign mass, age, body mass index (BMI, educational level, marital status, smoking status, physical (PCS and mental (MCS summary scores of the SF-36. Multiple regression analysis was used to determine the influence of these variables on FACT-G domain scores (physical, functional, social and emotional well-being. Results Data were collected on 157 women at their pre-operative visit (33 ovarian cancer, 45 endometrial cancer, 79 determined at surgery to be benign. Mean scores on the FACT-G subscales and SF-36 summary scores did not differ as a function of surgical diagnosis. PCS, MCS, age, and educational level were positively correlated with physical well-being, while increasing BMI was negatively correlated. Functional well-being was positively correlated with PCS and MCS and negatively correlated with BMI. Social well-being was positively correlated with MCS and negatively correlated with BMI and educational level. PCS, MCS and age were positively correlated with emotional well

    In an attempt to ensure high standards of cancer care, there is increasing interest in determining and monitoring the quality of interventions in surgical oncology. In recent years, this has been particularly the case for melanoma surgery. The vast majority of patients with melanoma undergo surgery. Usually, this is with combinations of wide excision, sentinel lymph node biopsy and lymphadenectomy. The indications for these procedures evolved during a time when no effective systemic adjuvant therapy was available, and whilst the rationale has been sound, the justification for differences in extent and thoroughness has generally been supported by inadequate or low-level evidence. This has led to a substantial variation among melanoma centres or even among surgeons within a centre in how these procedures are done. With recent rapid progress in the efficacy of systemic treatments that are impacting on overall survival, the prospect of long-term survival in these previously high risk patients means that more than ever long-term locoregional control of melanoma is imperative. Furthermore, the understanding of effects of systemic therapy on locoregional disease will only be interpretable if surgeons use standardized, high quality techniques. This article focuses on standardization and evolution of quality indicators for melanoma surgery and how these might have a positive impact on patient care.

    -term outcomes - Urinary continence - Erectile function Summary of Findings Robotic use for gynecologic oncology compared to: Laparotomy: benefits of robotic surgery in terms of shorter length of hospitalization and less blood loss. These results indicate clinical effectiveness in terms of reduced morbidity and safety, respectively, in the context of study design limitations. The beneficial effect of robotic surgery was shown in pooled analysis for complications, owing to increased sample size. More work is needed to clarify the role of complications in terms of safety, including improved study designs, analysis and measurement. Laparoscopy: benefits of robotic surgery in terms of shorter length of hospitalization, less blood loss and fewer conversions to laparotomy likely owing to the technical difficulty of conventional laparoscopy, in the context of study design limitations. Clinical significance of significant findings for length of hospitalizations and blood loss is low. Fewer conversions to laparotomy indicate clinical effectiveness in terms of reduced morbidity. Robotic use for urologic oncology, specifically prostate cancer, compared to: Retropubic surgery: benefits of robotic surgery in terms of shorter length of hospitalization and less blood loss/fewer individuals requiring transfusions. These results indicate clinical effectiveness in terms of reduced morbidity and safety, respectively, in the context of study design limitations. There was a beneficial effect in terms of decreased positive surgical margins and erectile dysfunction. These results indicate clinical effectiveness in terms of improved cancer control and functional outcomes, respectively, in the context of study design limitations. Surgeon skill had an impact on cancer control and functional outcomes. The results for complications were inconsistent when measured as either total number of complications, pain management or anastomosis. There is some suggestion that robotic surgery is safe with respect to

    Approximately 20% of laparoscopic colonic tumor resections result in conversion to open surgery. This result may be related to an increased risk in terms of the oncologic outcome. This study aimed to investigate the oncologic consequences of early and late conversion in laparoscopic colonic surgery. For this study, 45 male WAG-Rij rats were randomized into three operation groups of 15 animals each: laparotomy (LT group), laparoscopy followed by early conversion after 20 min (EC group), and laparoscopy followed by late conversion after 40 min (LC group). The total procedure time for the LT and EC groups was 60 min, compared with 80 min for the LC group. Hematogenous metastatic spread was induced in each operation group by tumor cell inoculation of a rat colon adenocarcinoma (CC 531) into the portal vein after 15 min of surgical intervention. A cecal resection was performed after 30 min in the LT and EC groups and after 50 min in the LC group. On day 28 after surgery, hepatic tumor growth was evaluated by measuring the diameter of tumor nodules, the tumor volume, the weight of the liver, and the cancer index. Hepatic tumor volume was significantly increased after LC than after EC (p = 0.01) and LT (p = 0.04). The liver weights in the LC group were significantly higher than in the EC (p = 0.01) and LT (p = 0.01) groups. No significant difference between EC and LT was observed in any parameters surveyed. The LC procedure resulted in greater tumor growth than EC and LT. The EC procedure did not lead to significantly more hepatic tumor growth than the same procedure performed using the conventional open technique. From the oncologic point of view, an early decision for conversion must be recommended as soon as any prolonged operating time has to be hypothesized.

    Background Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is a leading cause of death in cancer patients. The aim of this study was to explore the potential risk factor of VTE in oral and maxillofacial oncological surgery. Material and Methods The data of patients who received operation in our institution were gathered in this retrospective study. A diagnosis of VTE was screened and confirmed by computer tomography angiography (CTA) of pulmonary artery or ultrasonography examination of lower extremity. Medical history and all perioperative details were analyzed. Results 14 patients were diagnosed as VTE, including 6 cases of PE, 7 cases of DVT, 1case of DVT and PE. The mean age of these patients was 62.07 years. Reconstruction was performed in 12 patients of these cases, most of which were diagnosed as malignance. Mean length of surgery was 8.74 hours, and lower extremity deep venous cannula (DVC) was performed in all these patients. Conclusions We analyzed several characters of oral and maxillofacial surgery and suggested pay attention to lower extremity DVC which had a high correlation with DVT according to our data. Key words:Venous thromboembolism, pulmonary embolism, deep vein thrombosis, oral and maxillofacial surgery. PMID:27918738

    Comparative studies suggest that patients treated with oncoplastic breast conservation surgery (OBCS) have similar pathology to patients treated with wide local excision (WLE). However, patients treated with OBCS have never been compared to patients treated with mastectomy. The aim of this study was to identify which control group was comparable to patients undergoing OBCS. Commonly reported histopathological variables of patients treated with OBCS, WLE or mastectomy ± immediate reconstruction (Ms ± IR) were compared using Fisher Exact or Chi squared tests. 1000 patients' data were analysed (OBCS: n = 119; WLE: n = 600; Ms ± IR: n = 281). Tumour size was significantly bigger after OBCS than WLE (p mastectomy patients' histopathological results are in sharp contrast with previously published data. This study suggests that oncological outcomes following OBCS should be compared to mastectomy besides WLE. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Robot-assisted surgery has become more widespread in gynecological oncology. The purpose of this systematic review is to present current knowledge on robot-assisted surgery, and to clarify and discuss controversies that have arisen alongside the development and deployment. A database search in PubMed and EMBASE was performed up until 4 March 2016. The search strategy was developed in collaboration with an information specialist, and by application of the PRISMA guidelines. Human participants and English language were the only restrictive filters applied. Selection was performed by screening of titles and abstracts, and by full text scrutiny. From 2001 to 2016, a total of 76 references were included. Robot-assisted surgery in gynecological oncology has increased, and current knowledge supports that the oncological safety is similar, compared with previous surgical methods. Controversies arise because current knowledge does not clearly document the benefit of robot-assisted surgery, on perioperative outcome compared with the increased costs of the acquisition and application. The rapid development in robot-assisted surgery calls for long-term detailed prospective cohorts or randomized controlled trials. The costs associated with acquisition, application, and maintenance have an unfavorable impact on cost-benefit evaluations, especially when compared with laparoscopy. Future developments in robot-assisted surgery will hopefully lead to competition in the market, which will decrease costs. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    Background Quality of life (QoL) has become increasingly important in cancer treatment. It refers to the patient’s perception of the effects of the disease and therapy, and their impact on daily functioning and general feeling of well being. Material and Methods n this prospective study, a total of 100 patients treated at our institution, completed the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire and the specific EORTC QLQ-H&N35 module. The questionnaires were distributed to the patients between 12 and 60 months postoperatively. Results Global QoL score was 58.3 and mean score for functioning scale was 76.7. Fatigue (28.7 ± 26.1), followed by financial problems (27.7 ± 33.5), insomnia (26.7 ± 34.5) and pain (26.3 ± 29.9) had highest symptom score on QLQ-C30. Fatigue (r=-0.488), insomnia (r=-0.416) and pain (r =-0.448) showed highest value for significantly negative correlation to global QoL. In the H&N35 module, restriction of mouth opening (43.3 ± 38.6), dry mouth (40.7 ± 36.9), sticky saliva (37.3 ± 37.1) and eating in public (33.8 ± 31.9) were the four worst symptoms. Swallowing problem (r=-0.438), eating in public (r=-0.420) and persistent severe speech (r=-0.398) ranked as the three worst symptoms with highest value for significantly negative correlation to global QoL. Conclusions Longterm QoL after oncologic surgery and microvascular free flap reconstruction in patients with oral cancer is satisfactory. Measuring QoL should be considered as part of the evaluation of cancer treatment. Key words:Longterm quality of life, oral cancer, oncologic surgery, microvascular free flap reconstruction.

    The use of a self-expanding metallic stent as a bridge to surgery in acute malignant left colonic obstruction has been suggested as an alternative treatment to emergency surgery. The aim of the present study was to compare the morbi-mortality, cost-benefit and long-term oncological outcomes of both therapeutic options. This is a prospective, comparative, controlled, non-randomized study (2005-2010) performed in a specialized unit. The study included 82 patients with left colon cancer obstruction treated by stent as a bridge to surgery (n=27) or emergency surgery (n=55) operated with local curative intention. The main outcome measures (postoperative morbi-mortaliy, cost-benefit, stoma rate and long-term oncological outcomes) were compared based on an "intention-to-treat" analysis. There were no significant statistical differences between the two groups in terms of preoperative data and tumor characteristics. The technically successful stenting rate was 88.9% (11.1% perforation during stent placement) and clinical success was 81.4%. No difference was observed in postoperative morbi-mortality rates. The primary anastomosis rate was higher in the bridge to surgery group compared to the emergency surgery group (77.8% vs. 56.4%; P=.05). The mean costs in the emergency surgery group resulted to be €1,391.9 more expensive per patient than in the bridge to surgery group. There was no significant statistical difference in oncological long-term outcomes. The use of self-expanding metalllic stents as a bridge to surgery is a safe option in the urgent treatment of obstructive left colon cancer, with similar short and long-term results compared to direct surgery, inferior mean costs and a higher rate of primary anastomosis.

    Pancreaticoduodenectomy (PD) is a very complex operation. Its development took place very slowly at the most prestigious centers in the world. The aim of this investigation is to know who were the first surgeons to perform a PD in Spain as well as its historical circumstances. Despite all kinds of difficulties and very few resources, the first PD in Spain were carried out in Barcelona at the Hospital de la Santa Creu i Sant Pau where from the mid-50s a school of gastrointestinal surgery emerged with surgeons soon to become the spearhead of the Spanish surgery and a reference for the whole country: Pi-Figueras, Vicente Artigas, Antonio Soler-Roig and Antonio Llauradó. Almost simultaneously, in Oviedo, Luis Estrada also introduced the PD and total pancreaticoduodenectomy after a period of training with the pioneers of pancreatic surgery in the United States.

    Dermatosurgery and dermatooncology are an integral part of dermatology as a speciality, and this postulate is strictly respected in a high percentage of European dermatological units. Due to the fact that a number of other specialties interweave with the subject of therapy - the surgical treatment of the patient with skin tumors, the positioning of dermatosurgery as part of dermatology is generally controversial (according to some), and at the same time is often the subject of a number of debates and conflicts. These include maxillofacial surgeons, plastic surgeons, regenerative and reconstructive surgeons, surgical and medical oncologist, etc. The advantages of these specialities are mainly based on good medical practice and good surgical techniques that are applied. In contrast, their disadvantages are based on the lack of good awareness of the initial surgical approach as well as the need for time-adjusted and accurately performed additional surgical interventions which should befurthermore careful scheduled with the relevant oncology units. Losing this thread, in practice, it turns out that we are losing the patients themselves or, looking laconically, we are working with reduced efficiency and effectiveness. Although for the last 15 years the positions of these sub-sectors in Bulgaria had been underdeveloped, a certain ascent has been observed nowadays or from a couple of years ago. This advance is undoubtedly due to the influence of the German Dermatological School, presented by Prof. Dr. Uwe Wollina, Head of Department of Dermatology, Venereology and Allergology in Dresden, Germany, as well as due to other respected representative of the Italian Dermatological School - in the face of Prof. Dr. Torello Lotti, Head of the Dermatology Unit at G Marconi University of Rome, Italy.

    Radical ablative surgery and radial forearm free flap (RFFF) reconstruction provide promising oncologic and functional results in patients with oral or oropharyngeal cancer. To assess the postoperative outcomes and the oncologic and functional results, with their main predictive factors, after radical ablative surgery and RFFF reconstruction for patients with oral or oropharyngeal cancer. Between 2000 and 2006, we prospectively analyzed the postoperative, oncologic and functional outcomes of all previously untreated patients who underwent this type of surgery. A total of 132 patients were enrolled in this study. There were three RFFF failures. The rate of surgical complications was 20%. The 5-year locoregional control and overall survival rates were 68% and 52%, respectively. Advanced age, high comorbidity index, elevated overall stage and tumoral involvement of the inner part of the cheek were correlated with a lower overall survival rate. A good functional result was obtained for oral diet, speech, mouth opening and aesthetic outcome in 87%, 80%, 86% and 88% of the patients, respectively. High comorbidity index, large flap surface, radiotherapy and tumoral involvement of the mobile tongue were significant predictors of poorer functional or aesthetic outcomes.

    There are many papers comparing two antibiotic protocols for the profilaxis of head and neck infections after laryngeal surgery. We present one prospective and randomised study in 60 patients comparing the efficacy of two protocols. The comparison was between ceftriaxone versus the association of clindamicyn and gentamicyn. In our database we included the risk factors for infection, the surgical approach, the duration of surgery and the patient characteristics. We observed an incidence of 28% of infection, with a 23.3% in the clindamicyn + gentamicyn group and a 33.3% in the ceftriaxone group. The differences between the two groups were not statistically significant. In this study we observed a small difference between the amount of alcohol comsuption, the effectiveness of the surgical drainage, the surgical approach and the presence of wound infection. The difference was not statistical significant due to the small group of patients. The profilaxis was adequate for the total laryngectomy and cordectomy group, with a higher incidence of wound infection in patients treated with a supraglottic laryngectomy.

    Costs, length of hospital staying and morbidity are frequently and significantly increased as a result of infections and other complications following surgical procedure for gastrointestinal tract cancer. Recently, improving host defence mechanisms have become a target of interest. Immunonutrition aims at improving immunity, most likely providing key nutrients to maintain T-lymphocyte and other host defence. To evaluate the immunonutrition in cancer patients who are operated by digestive diseases and assess the cost-effectiveness of this supplementation. This study consisted of a systematic review of the literature based on reference analyses retrieved from current databases such as PubMed, Lilacs and SciELO. The search strategy was defined by terms related to immunonutrition [immunonutrition, arginine, omega-3 and nucleotides] in combination with [costs, cost-effective and cost-effectiveness] as well as [gastrointestinal cancer surgery, oesophageal, gastric or pancreatic surgery] in English, Portuguese or Spanish language. For cost analyses, currencies used in the manuscripts were all converted to American dollars (US$) in order to uniform and facilitate comparison. Six prospective randomized studies were included in this review. The cost-effectiveness was positive in most of studies, demonstrating that this diet can significantly reduce hospital costs in the North hemisphere. However, similar studies needed to be carried to determine such results among us. Custos, tempo de hospitalização e morbidade estão frequentemente aumentados na presença de infecções e outras complicações decorrentes de procedimentos cirúrgicos para o câncer gastrointestinal.

    We present the results of a retrospective study of 817 patients treated with conservative surgery for carcinomas of the supraglottic larynx at ENT department of the Gregorio Maranón Hospital between 1962-1993. The disease was staged using the criteria set forth in 1988 by the AJCC, and 36,2% were stages III and IV. From the 817 patients treated with conservative surgery 230 were extended supraglottic laryngectomies. Our theoretic treatment protocol is presented. The 5 years actuarial uncorrected survival rate related to stage was 83,9%, 83,2%, 78,5% and 55,3% for stages I, II, III and IV respectively. Local-regional failure occurred in 32,9% patients overall, and the most common site for local-regional failure was the cervical nodes. The 5 years local control rate related to stage was 86,97%, 89,1%, 82,15% and 66,55% for stages I, II, III and IV respectively. In extended supraglottic laryngectomies the 5 years uncorrected survival rate was 62,6% in supraglottic laryngectomies (SL) extended to the base of the tongue, 62,5% in SL extended to the hypopharynx, 72,5% in SL extended to the arythenoyd and 79,4% in SL extended to the vocal chord. The 5 years local control rate was 87% in SL extended to the base of the tongue, 85,7% in SL extended to the hypopharynx, 97% in SL extended to the arythenoid and 90,8% in SL extended to the vocal chord. Functional results have been evaluated according to a three grade scale. Good and fair results were 97.6% for swallowing, 90% for respiration and 95.8% for the quality of voice.

    Total forearm free flap procedures after forequarter amputations have been sparsely described in the literature. Using the amputated arm as a "free filet flap" remains a viable surgical option after radical forequarter amputations performed for the resection of large, invasive tumors of the shoulder or thoracic wall region. Using the forequarter specimen as a donor site seems favorable in that it eliminates the usual donor site morbidity. Nevertheless, in our patient with invasive ductal carcinoma of the breast and a fibrosarcoma suffering from severe pain and septic conditions - which failed to respond properly to conservative therapy - as well as rapidly progressive tumor ulceration despite repeated radiation therapy, we decided to attempt complete tumor removal by hemithoracectomy as a last resort. This decision was taken following multiple interdisciplinary consultations and thorough patient information. Although technically feasible with complete tumor removal and safe soft tissue free flap coverage, the postoperative course raises questions about the advisability of such ultra radical surgical procedures, as well as about the limitations of respiratory recovery after hemithoracectomy with removal of the sternum. Hence, based on our experience with such radical tumor surgery, we discuss the issues of diminished postoperative pulmonary function, intensive care possibilities and ethical issues.

    Full Text Available Marco Noventa, Salvatore Gizzo, Lorena Conte, Angela Dalla Toffola, Pietro Litta, Carlo Saccardi Department of Woman and Child Health, University of Padua, Padua, Italy Background: Endometrial stromal sarcoma (ESS is a term used to define a rare neoplasm that accounts for approximately 0.2%–1% of all uterine malignancies; it is, however, implicated in an estimated 10%–15% of those malignancies with a mesenchymal component. Recent evidence suggests that while the preservation of the ovaries may be considered appropriate in premenopausal women, hysterectomy and bilateral salpingo-oophorectomy remains the recommended treatment in postmenopausal women. Currently, only a few case series reporting the treatment of ESS in young women with a desire to preserve fertility and thus subjected to a fertility-sparing surgery are available in the literature. Case presentation: We report a peculiar case of early stage ESS treated by laparoscopic fertility-sparing surgery and a strict follow-up program (every 3 months of imaging and clinical evaluation. The patient remained disease free 1 year after primary treatment. Three months after completing oncological follow-up, the patient conceived spontaneously and is, to date, pregnant at 11 weeks of gestation without evidence of recurrent disease or obstetric complications. Conclusion: Based on our case report and in accordance with the data available, we suggest that in young patients affected by early stage ESS who wish to preserve reproductive function, fertility-sparing surgery could represent a valid option, though strict oncological follow-up remains mandatory.

    Full Text Available The use of the oncological principle – en bloc ablastic tumor resection – can expect a breakthrough in the treatment of baseline unfavorable patient groups. In the described case of atypical meningioma, its en bloc resection presents significant technical difficulties when accomplishing the task associated with the giant sizes of a tumor as an iceberg growing outside and into the cranial cavity, its rich vascularization from both the internal and external carotid artery system, with the involvement of the superior sagittal sinus, the presence of a dense bone crown that combines the three-component construction of a neoplasm, which made difficult safe mobilization and scanning in the cranial cavity.In such topographic variants, the criteria for the Simpson radical meningioma resection are inapplicable and only en bloc tumor resection may reflect the oncological principles of surgery. The technologies of en bloc resection of intracranial meningiomas should be more frequently used because preoperative neurovisualization and even histological diagnosis does not always allow the grade of meningiomas to be specified.

Methods We identified 50 patients with a median age of 65 years, who underwent radical surgical treatment for RCC and tumor thrombus of the IVC between 1997 and 2010. The charts were reviewed for pathological and surgical parameters, as well as complications and oncological outcome. Results The median follow-up was 26 months. In 21 patients (42% distant metastases were already present at the time of surgery. All patients underwent radical nephrectomy, thrombectomy and lymph node dissection through a flank (15 patients/30%, thoracoabdominal (14 patients/28% or midline abdominal approach (21 patients/42%, depending upon surgeon preference and upon the characteristics of tumor and associated thrombus. Extracorporal circulation with cardiopulmonary bypass (CPB was performed in 10 patients (20% with supradiaphragmal thrombus of IVC. Cancer-specific survival for the whole cohort at 5 years was 33.1%. Survival for the patients without distant metastasis at 5 years was 50.7%, whereas survival rate in the metastatic group at 5 years was 7.4%. Median survival of patients with metastatic disease was 16.4 months. On multivariate analysis lymph node invasion, distant metastasis and grading were independent prognostic factors. There was no statistically significant influence of level of the tumor thrombus on survival rate. Indeed, patients with supradiaphragmal tumor thrombus (n = 10 even had a better outcome (overall survival at 5 years of 58.33% than the entire cohort. Conclusions An aggressive surgical approach is the most effective therapeutic option in patients with RCC and any level of tumor thrombus and offers a reasonable longterm survival. Due to good clinical and oncological outcome we prefer the use of CPB with extracorporal

    Successful therapeutic interventions to prevent disease progression in patients with nonmetastatic osteosarcoma have included surgery with adjuvant chemotherapy. Presurgical chemotherapy has been advocated for these patients because of putative improvement in event-free survival (EFS). The advantages of presurgical chemotherapy include early administration of systemic chemotherapy, shrinkage of primary tumor, and pathologic identification of risk groups. The theoretic disadvantage is that it exposes a large tumor burden to marginally effective chemotherapy. The contribution of chemotherapy and surgery timing has not been tested rigorously. Between 1986 and 1993, we conducted a prospective trial in patients with nonmetastatic osteosarcoma who were assigned randomly to immediate surgery or presurgical chemotherapy. Except for the timing of surgery (week 0 or 10), patients received 44 weeks of identical combination chemotherapy that included high-dose methotrexate with leucovorin rescue, doxorubicin, cisplatin, bleomycin, cyclophosphamide, and dactinomycin. One hundred six patients were enrolled onto this study. Six were excluded from analysis. Of the remaining 100 patients, 45 were randomly assigned to immediate chemotherapy, and 55 were randomly assigned to immediate surgery. Sixty-seven patients remain disease-free. At 5 years, the projected EFS +/- SE is 65% +/- 6% (69% +/- 8% for immediate surgery and 61% +/- 8% for presurgical chemotherapy; P =.8). The treatment arms had similar incidence of limb salvage (55% for immediate surgery and 50% for presurgical chemotherapy). Chemotherapy was effective in both treatment groups. There was no advantage in EFS for patients given presurgical chemotherapy.

    Disparities in breast cancer incidence and outcome between African American and white American women are multifactorial in etiology. The increased frequency of triple-negative breast cancers (TNBC) in African American patients suggests the possible contribution of hereditary factors related to African ancestry. The University of Michigan (UM)-Komfo Anoyke Teaching Hospital (KATH) Breast Cancer Research Collaborative and International Breast Registry was established in 2004. It features epidemiologic information, tumor tissue, and germline DNA specimens from African American, white American, and Ghanaian women. This research collaborative has generated valuable findings regarding the pathogenesis and patterns of TNBC while concomitantly improving the standard of breast oncology care in Ghana. This partnership has also yielded important opportunities for academic and educational exchange. It has expanded to involve other sites in Africa and Haiti. The UM-KATH collaborative is a model for demonstrating the research and academic exchange value of international partnerships.

    We quantified the underestimation of hospital readmission rates that can occur with institutional databases and the incidence of care fragmentation among patients undergoing urological oncology procedures in a nationally representative database. The 2013 Nationwide Readmissions Database was queried for patients undergoing prostatectomy, cystectomy, nephroureterectomy, nephrectomy, partial nephrectomy and retroperitoneal lymph node dissection for urological malignancies. Nationally representative 30 and 90-day readmission and care fragmentation rates were calculated for all procedures. Readmission rates with and without nonindex hospital readmissions were compared with Pearson's chi-square test. Multivariable logistic regression models were used to identify predictors of care fragmentation at 90-day followup. For all surgical procedures readmission rates were consistently underestimated by 17% to 29% at 90-day followup. The rates of care fragmentation among readmitted patients were similar for all procedures, ranging from 24% to 34% at 90-day followup. Overall 1 in 4 readmitted patients would not be captured in institutional databases and 1 in 3 readmitted patients experienced care fragmentation. Multivariable models did not identify a predictor of care fragmentation that was consistent across all procedures. The high rate of underestimation of readmission rates across all urological oncology procedures highlights the importance of linking institutional and payer claims databases to provide more accurate estimates of perioperative outcomes and health care utilization. The high rate of care fragmentation across all procedures emphasizes the need for future efforts to understand the clinical relevance of care fragmentation in patients with urological malignancies, and to identify patients at risk along with potentially modifiable risk factors for care fragmentation.

    Surgical treatment used in gynecological oncology involves acute postoperative pain which requires efficient treatment. This study covered a group of 128 patients who were randomly divided into two groups. In the postoperative period patients in group I were administered morphine subcutaneously, acetaminophen intravenously and naproxen per rectum. The pain intensity level was checked by means of the pain intensity numeric rating scale (NRS). In the instances of pain rated at 5 or more, patients were additionally administered ketoprofen intravenously. Patients in group II were administered morphine, naproxen, and metamizole instead of acetaminophen and ketoprofen additionally. In group I after the administration of morphine and acetaminophen 22 patients (34.37%) needed additional doses of ketoprofen. In group II 33 women (51.56%) required ketoprofen after the administration of morphine and metamizole (N1 = 22 vs N2 = 33, p metamizol with morphine (without ketoprofen) gave worse analgesic results than acetaminophen with morphine, but the combination of morphine, acetaminophen and ketoprofen or morphine, metamizol and ketoprofen gave satisfactory analgesic results.

    One of the basic prerequisites for generating evidence-based data is the availability of classification systems. Attempts to date to classify breast cancer operations have focussed on specific problems, e.g. the avoidance of secondary corrective surgery for surgical defects, rather than taking a generic approach. Starting from an existing, simpler empirical scheme based on the complexity of breast surgical procedures, which was used in-house primarily in operative report-writing, a novel classification of ablative and breast-conserving procedures initially needed to be developed and elaborated systematically. To obtain proof of principle, a prospectively planned analysis of patient records for all major breast cancer-related operations performed at our breast centre in 2005 and 2006 was conducted using the new classification. Data were analysed using basic descriptive statistics such as frequency tables. A novel two-type, six-tier classification system comprising 12 main categories, 13 subcategories and 39 sub-subcategories of oncological, oncoplastic and reconstructive breast cancer-related surgery was successfully developed. Our system permitted unequivocal classification, without exception, of all 1225 procedures performed in 1166 breast cancer patients in 2005 and 2006. Breast cancer-related surgical procedures can be generically classified according to their surgical complexity. Analysis of all major procedures performed at our breast centre during the study period provides proof of principle for this novel classification system. We envisage various applications for this classification, including uses in randomised clinical trials, guideline development, specialist surgical training, continuing professional development as well as quality of care and public health research.

    For the period from September 2010 to September 2014 there were operated 513 patients with endometrial cancer using laparoscopic installation the Karl Storz company. 304 patients (59.2%) underwent hysterectomy with appendages, 209 (40.8%)--hysterectomy with appendages and pelvic lymphadenectomy, including 11 patients (2.2%) with the addition of omentectomy in serous and serous-papillary forms of endometrial cancer. The average age of patients was 58.4 years (44-75 years). Body mass index over 25.0 was determined in 456 patients (88.9%), of whom 183 patients (35.6%) had an excess of body weight, in 159 (31.0%)--obesity of I degree, in 79 (15.5%)--obesity of II degree and in 35 patients (6.8%)--obesity of III degree. There were no reported complications during surgery. The postoperative period in the majority of patients was characterized by the minimal complications and absence of contraindications for adjuvant radiotherapy. During follow-up period there were registered 4 relapses: in 1 patient with serous--papillary form of endometrial cancer during the first year after surgery--in the form of dissemination of tumor in the abdomen and pelvis; in 3 patients--in the form of a cytological detection of glandular cancer cells in vaginal stump. As a result, regardless of age and comorbidities, laparoscopy allows performing to endometrial cancer patients the entire volume of planned radical surgery with minimum damage and with minimal risk of intra- and postoperative complications, favorable and accelerated rehabilitation period.

    Oncology research has traditionally been conducted using techniques from the biological sciences. The new field of computational oncology has forged a new relationship between the physical sciences and oncology to further advance research. By applying physics and mathematics to oncologic problems, new insights will emerge into the pathogenesis and treatment of malignancies. One major area of investigation in computational oncology centers around the acquisition and analysis of data, using improved computing hardware and software. Large databases of cellular pathways are being analyzed to understand the interrelationship among complex biological processes. Computer-aided detection is being applied to the analysis of routine imaging data including mammography and chest imaging to improve the accuracy and detection rate for population screening. The second major area of investigation uses computers to construct sophisticated mathematical models of individual cancer cells as well as larger systems using partial differential equations. These models are further refined with clinically available information to more accurately reflect living systems. One of the major obstacles in the partnership between physical scientists and the oncology community is communications. Standard ways to convey information must be developed. Future progress in computational oncology will depend on close collaboration between clinicians and investigators to further the understanding of cancer using these new approaches.

    The objective of this study is to analyse local recurrence rates in patients receiving neoadjuvant chemotherapy (nCT) comparing mastecomized (MX) patients with those undergoing breast conserving therapy (BCT). Patients undergoing breast cancer surgery after nCT (3xCMF or 3-6xED) between 1995 and 2007 at our department were retrospectively analysed. The median follow up was 60 months for 308 patients. Patients who were downsized from MX to BCT with partial or complete response (n = 104) had a similar local recurrence free survival (LRFS) compared to patients who did not experience successful downsizing (n = 67) and finally undergoing MX (LRFS MX-BCT 81% vs. MX-MX 91%; P = 0.79). Uni- and multivariate analyses demonstrated that BCT itself was not an independent prognostic factor for a worse LRFS (P = 0.07 and 0.14). After no pathologic change or progressive disease the risk of local recurrence was increased in patients undergoing BCT (MX-BCT; n = 6 LRFS 66%) compared with MX (n = 44; LRFS 90%; P = 0.04). Overall survival in general was better for the BCT group (n = 197) compared with MX group (n = 111) regardless of clinical response (92% vs. 72%; P downsizing by nCT in patients primarily scheduled for mastectomy. These patients, however, should not be treated with breast conservation in the absence of any proven response after nCT.

    In modern multi-disciplinary cancer treatment, rehabilitation and functional results represent utmost intent in reconstructive surgery of the oral cavity. Even in cases where the stage of disease is advanced) and the perspective of survival is limited, it is possible to achieve an acceptable quality of life. The authors report, in this study, the morpho-functional results and the morbidity observed in glossectomies in which the reconstruction was performed using three different methods. In a total of 264 reconstructive flaps of the head and neck regions, the authors considered three groups of 15 patients that had had reconstruction after the demolitive procedure. Respectively these groups were divided by the followed methods: free forearm flap, pectoralis major myocutaneous flap and nasolabial flap. The morbidity showed an extremely low rate of flap loss in all the groups, but "minor" complications, such as fistulas and leakages, were significantly more frequent in the myocutaneous flaps group. Functional evaluation for speech and deglutition showed good results in most patients. Extremely severe postoperative conditions as a permanent NG tube or incomprehensible speech had been observed in less than 15% of the cases. Particularly, the pectoralis major flap, showed its best functional performances in the total or subtotal glossectomies with a sacrifice of the muscles of the oral floor. The free forearm flap is reliable and safe with its low thickness and pliability, especially for partial glossectomies. The nasolabial flap was confirmed to be the first reconstructive choice for selected limited resections of the tongue and of the antero-lateral floor. With this experience it is possible, even in more complex free flaps, to reduce the time consumption and the complication rate. Free flaps do not substitute routinely myocutaneous and conventional flaps, but they represent the "ideal" reconstructive alternatives for specific and selected indications.

    Intraoperative in situ identification of (18)F-FDG-avid tissue sites during radioguided oncologic surgery remains a significant challenge for surgeons. The purpose of our study was to evaluate the 1.5-to-1 ratiometric threshold criteria method versus the three-sigma statistical threshold criteria method for determination of gamma detection probe positivity for intraoperative in situ identification of presumed abnormal (18)F-FDG-avid tissue sites in a manner that was independent of the specific type of gamma detection probe used. From among 52 patients undergoing appropriate in situ evaluation of presumed abnormal (18)F-FDG-avid tissue sites during (18)F-FDG-directed surgery using 6 available gamma detection probe systems, a total of 401 intraoperative gamma detection probe measurement sets of in situ counts per second measurements were cumulatively taken. For the 401 intraoperative gamma detection probe measurement sets, probe positivity was successfully met by the 1.5-to-1 ratiometric threshold criteria method in 150/401 instances (37.4%) and by the three-sigma statistical threshold criteria method in 259/401 instances (64.6%) (P < 0.001). Likewise, the three-sigma statistical threshold criteria method detected true positive results at target-to-background ratios much lower than the 1.5-to-1 target-to-background ratio of the 1.5-to-1 ratiometric threshold criteria method. The three-sigma statistical threshold criteria method was significantly better than the 1.5-to-1 ratiometric threshold criteria method for determination of gamma detection probe positivity for intraoperative in situ detection of presumed abnormal (18)F-FDG-avid tissue sites during radioguided oncologic surgery. This finding may be extremely important for reshaping the ongoing and future research and development of gamma detection probe systems that are necessary for optimizing the in situ detection of radioisotopes of higher-energy gamma photon emissions used during radioguided oncologic surgery.

    There is uncertainty regarding the oncologic effectiveness of kidney-sparing surgery (KSS) compared with radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). To systematically review the current literature comparing oncologic outcomes of KSS versus RNU for UTUC. A computerised bibliographic search of the Medline, Embase, and Cochrane databases was performed for all studies reporting comparative oncologic outcomes of KSS versus RNU. Approaches considered for KSS were segmental ureterectomy (SU) and ureteroscopic (URS) or percutaneous (PC) management. Using the methodology recommended by the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, we identified 22 nonrandomised comparative retrospective studies published between 1999 and 2015 that were eligible for inclusion in this systematic review. A narrative review and risk-of-bias (RoB) assessment were performed using cancer-specific survival (CSS) as the primary end point. Seven studies compared KSS overall (n=547) versus RNU (n=1376). Information on the comparison of SU (n=586) versus RNU (n=3692), URS (n=162) versus RNU (n=367), and PC (n=66) versus RNU (n=114) was available in 10, 5, and 2 studies, respectively. No significant difference was found between SU and RNU in terms of CSS or any other oncologic outcomes. Only patients with low-grade and noninvasive tumours experienced similar CSS after URS or PC when compared with RNU, despite an increased risk of local recurrence following endoscopic management of UTUC. The RoB assessment revealed, however, that the analyses were subject to a selection bias favouring KSS. Our systematic review suggests similar survival after KSS versus RNU only for low-grade and noninvasive UTUC when using URS or PC. However, selected patients with high-grade and invasive UTUC could safely benefit from SU when feasible. These results should be interpreted with caution due to the risk of selection bias. We reviewed the studies that

    This phase II trial evaluated the effect of neoadjuvant chemotherapy with or without second-look surgery before craniospinal irradiation on response rates and survival outcomes in children with newly diagnosed non-germinomatous germ cell tumors. Induction chemotherapy consisted of six cycles of carboplatin/etoposide alternating with ifosfamide/etoposide. Patients demonstrating less than complete response after induction chemotherapy were encouraged to undergo second-look surgery. Patients who did not achieve complete response or partial response after chemotherapy with or without second-look surgery proceeded to high-dose chemotherapy with thiotepa and etoposide and autologous peripheral blood stem-cell rescue before craniospinal irradiation. The study included 102 patients treated between January 2004 and July 2008. Median age was 12 years, and 76% were male; 53.9% had pineal region masses, and 23.5% had suprasellar lesions. Sixty-nine percent of patients achieved complete response or partial response with neoadjuvant chemotherapy. At 5 years, event-free survival was 84% ± 4% (SE) and overall survival was 93% ± 3%. During the median follow-up of 5.1 years, 16 patients recurred or progressed, with seven deaths after relapse. No deaths were attributed to therapy-related toxicity. Relapse occurred at the site of primary disease in 10 patients, at a distant site in three patients, or both in one patient. In two patients, progression was detected by marker increase alone. Increased serum α-fetoprotein was a negative prognostic variable. Histologic subtype and increase of beta-human chorionic gonadotropin were not significantly correlated with worse outcomes. Neoadjuvant chemotherapy with or without second-look surgery achieved high response rates contributing to excellent survival outcomes in children with newly diagnosed non-germinomatous germ cell tumors. This regimen should be included as a backbone for further studies. © 2015 by American Society of Clinical

    To determine the significance of gastric outlet obstruction (GOO) on the outcomes of radical surgery for distal gastric cancer. Three hundred seventy-one patients who underwent radical surgery for advanced gastric cancer arising at the distal stomach were categorized into two groups according to the presence of GOO, that is, 59 patients with GOO and 312 patients without. Clinicopathologic variables, postoperative morbidity and mortality, recurrence pattern, and survival outcomes of the two groups were compared. Distal gastric carcinoma with GOO was usually diagnosed at a more advanced stage with aggressive pathologic features. GOO adversely affected overall survival after radical surgery with an odds ratio of 2.068 (P gastric cancer and provide additional information for identifying patients at higher risk of recurrence and pattern of recurrence during follow-up. Radical surgery in patients with GOO can be performed with acceptable morbidity and mortality.

    Full Text Available An oncologic emergency is defined as any acute, potentially life-threatening event, either directly or indirectly related to a patient′s cancer (ca or its treatment. It requires rapid intervention to avoid death or severe permanent damage. Most oncologic emergencies can be classified as metabolic, hematologic, structural, or side effects from chemotherapy agents. Tumor lysis syndrome is a metabolic emergency that presents as severe electrolyte abnormalities. The condition is treated with aggressive hydration, allopurinol or urate oxidase to lower uric acid levels. Hypercalcemia of malignancy is treated with aggressive rehydration, furosemide, and intravenous (IV bisphosphonates. Syndrome of inappropriate antidiuretic hormone should be suspected if a patient with ca presents with normovolemic hyponatremia. This metabolic condition usually is treated with fluid restriction and furosemide. Febrile neutropenia is a hematologic emergency that usually requires inpatient therapy with broad-spectrum antibiotics, although outpatient therapy may be appropriate for low-risk patients. Hyperviscosity syndrome usually is associated with Waldenstrφm′s macroglobulinemia, which is treated with plasmapheresis and chemotherapy. Structural oncologic emergencies are caused by direct compression of surrounding structures or by metastatic disease. Superior vena cava syndrome is the most common structural oncological emergency. Treatment options include chemotherapy, radiation, and IV stenting. Epidural spinal cord compression can be treated with dexamethasone, radiation, or surgery. Malignant pericardial effusion, which often is undiagnosed in ca patients, can be treated with pericardiocentesis or a pericardial window procedure.

    Radical trachelectomy is the treatment of choice in women with early-stage cervical cancer wishing to preserve fertility. Radical trachelectomy can be performed with a vaginal, abdominal, or laparoscopic/robotic approach. Vaginal radical trachelectomy (VRT) is generally not offered to patients with tumors 2cm or larger because of a high recurrence rate. There are no conclusive recommendations regarding the safety of abdominal radical trachelectomy (ART) or laparoscopic radical trachelectomy (LRT) in such patients. Several investigators have used neoadjuvant chemotherapy in patients with tumors 2 to 4cm to reduce tumor size so that fertility preservation may be offered. However, to our knowledge, no published study has compared outcomes between patients with cervical tumors 2cm or larger who underwent immediate radical trachelectomy and those who underwent neoadjuvant chemotherapy followed by radical trachelectomy. We conducted a literature review to compare outcomes with these 2 approaches. Our main endpoints for evaluation were oncological and obstetrical outcomes. The fertility preservation rate was 82.7%, 85.1%, 89%; and 91.1% for ART (tumors larger than >2cm), ART (all sizes), NACT followed by surgery and VRT (all sizes); respectively. The global pregnancy rate was 16.2%, 24% and 30.7% for ART, VRT, and NACT followed by surgery; respectively. The recurrence rate was 3.8%, 4.2%, 6%, 7.6% and 17% for ART (all sizes), VRT (all sizes), ART (tumors>2cm), NACT followed by surgery, and VRT (tumors>2cm). These outcomes must be considered when offering a fertility sparing technique to patients with a tumor larger than 2cm. Copyright © 2015 Elsevier Inc. All rights reserved.

    Nanotechnology, the manipulation of matter on atomic and molecular scales, is a relatively new branch of science. It has already made a significant impact on clinical medicine, especially in oncology. Nanomaterial has several characteristics that are ideal for oncology applications, including preferential accumulation in tumors, low distribution in normal tissues, biodistribution, pharmacokinetics, and clearance, that differ from those of small molecules. Because these properties are also well suited for applications in radiation oncology, nanomaterials have been used in many different areas of radiation oncology for imaging and treatment planning, as well as for radiosensitization to improve the therapeutic ratio. In this article, we review the unique properties of nanomaterials that are favorable for oncology applications and examine the various applications of nanotechnology in radiation oncology. We also discuss the future directions of nanotechnology within the context of radiation oncology. © 2014 by American Society of Clinical Oncology.

    With the movement towards bundled payments, stakeholders should know the true cost of the care they deliver. Time-driven activity-based costing (TDABC) can be used to estimate costs for each episode of care. In this analysis, TDABC is used to both estimate the costs of anesthesia care and identify the primary drivers of those costs of 11 common oncologic outpatient surgical procedures. Personnel cost were calculated by determining the hourly cost of each provider and the associated process time of the 11 surgical procedures. Using the anesthesia record, drugs, supplies and equipment costs were identified and calculated. The current staffing model was used to determine baseline personnel costs for each procedure. Using the costs identified through TDABC analysis, the effect of different staffing ratios on anesthesia costs could be predicted. Costs for each of the procedures were determined. Process time and costs are linearly related. Personnel represented 79% of overall cost while drugs, supplies and equipment represented the remaining 21%. Changing staffing ratios shows potential savings between 13% and 28% across the 11 procedures. TDABC can be used to estimate the costs of anesthesia care. This costing information is critical to assessing the anesthesiology component in a bundled payment. It can also be used to identify areas of cost savings and model costs of anesthesia care. CRNA to anesthesiologist staffing ratios profoundly influence the cost of care. This methodology could be applied to other medical specialties to help determine costs in the setting of bundled payments. Copyright © 2015 Elsevier Inc. All rights reserved.

    A shortage of surgeons has been a serious problem in recent years. There is an urgent need to utilize female surgeons who tend to resign because of bearing and raising of children. To examine possible measures to deal with the issue, we performed questionnaire survey about work-life balance and career planning on 20 female surgeons in the Department of Surgery and Oncology, Kyushu University. The response rate was 80.0%. In the 16 respondents, seven were unmarried and nine were married. A large fraction of the respondents recognized the importance of work-life-balance. Female surgeons have many difficulties to continue working with good work-life balance; therefore, understanding and cooperation of both their spouses and coworkers is considered to be necessary. Married female surgeons considered that improvement of the working environment and sufficient family support were more important for good work-life balance compared to those who were unmarried. Female surgeons should recognize the importance of improvement of their environment, including the workplace and the family to continue working with good work-life balance in youth and should have the prospects about their career plan of their own.

  10. Current management of surgical oncologic emergencies.

    Directory of Open Access Journals (Sweden)

    Marianne R F Bosscher

    Full Text Available For some oncologic emergencies, surgical interventions are necessary for dissolution or temporary relieve. In the absence of guidelines, the most optimal method for decision making would be in a multidisciplinary cancer conference (MCC. In an acute setting, the opportunity for multidisciplinary discussion is often not available. In this study, the management and short term outcome of patients after surgical oncologic emergency consultation was analyzed.A prospective registration and follow up of adult patients with surgical oncologic emergencies between 01-11-2013 and 30-04-2014. The follow up period was 30 days.In total, 207 patients with surgical oncologic emergencies were included. Postoperative wound infections, malignant obstruction, and clinical deterioration due to progressive disease were the most frequent conditions for surgical oncologic emergency consultation. During the follow up period, 40% of patients underwent surgery. The median number of involved medical specialties was two. Only 30% of all patients were discussed in a MCC within 30 days after emergency consultation, and only 41% of the patients who underwent surgery were discussed in a MCC. For 79% of these patients, the surgical procedure was performed before the MCC. Mortality within 30 days was 13%.In most cases, surgery occurred without discussing the patient in a MCC, regardless of the fact that multiple medical specialties were involved in the treatment process. There is a need for prognostic aids and acute oncology pathways with structural multidisciplinary management. These will provide in faster institution of the most appropriate personalized cancer care, and prevent unnecessary investigations or invasive therapy.

    Full Text Available Background: The standard treatment for locally advanced cancer of the rectum (LACR and selective cases of stage IV disease is preoperative chemoradiotherapy (CRT followed by total mesorectal excision (TME. Despite reductions in local recurrence, disease-free survival (DSF has remained stable in recent years. Objective: The objective of this study is to analyze patterns of recurrence, long-term survival and prognostic factors in a program of neoadjuvant CRT and surgery in LACR. Methods: Between January 1992 and December 2011, 446 patients with LACR and 54 patients (with single metastases were treated with pre-operative long course CRT and surgery. Three hundred forty four (66.8% anterior resections of the rectum and 123 (24.6% abdomino-perineal resections were performed. Results: With a mean follow-up of 70.06 months, local recurrence was 4.8% and distant recurrence 25.5%. No differences were found in the histopathologic prognostic factors across the three groups studied depending on distance (cm from the anal margin. Involvement of the circumferential resection margin (CRM+ was significantly greater in tumors in the distal third of the rectum (8.5%; p = 0.04. 67 patients (13.4% showed a complete pathologic response. DSF at 5 and 10 years was significantly lower in patients with tumors affecting the distal third as compared to the middle third of the rectum (61.9% vs. 57.7%; p = 0.04. Tumors at this distal location resulted in a significantly higher incidence of lung metastases (p = 0.016.

    2011-09-01

    Changing realities in surgery and surgical technique have heightened the need for agile adaptation in training programs. Current guidelines reflect the growing acceptance and adoption of the use of minimally invasive surgery (MIS) in oncology. North American general surgery residents are often not adequately skilled in advanced laparoscopic surgery skills at the completion of their residency. Presently, advanced laparoscopic surgery training during surgical oncology fellowship training occurs on an ad-hoc basis in many surgical oncology programs. We present a rational and template for a structured training in advanced minimally invasive surgical techniques during surgical oncology fellowship training. The structure of the program seeks to incorporate evidence-based strategies in MIS training from a comprehensive review of the literature, while maintaining essential elements of rigorous surgical oncology training. Fellows in this stream will train and certify in the Fundamentals of Laparoscopic Surgery (FLS) course. Fellows will participate in the didactic oncology seminar series continuously throughout the 27 months training period. Fellows will complete one full year of dedicated MIS training, followed by 15 months of surgical oncology training. Minimal standards for case volume will be expected for MIS cases and training will be tailored to meet the career goals of the fellows. We propose that a formalized MIS-Surgical Oncology Fellowship will allow trainees to benefit from an effective training curriculum and furthermore, that will allow for graduates to lead in a cancer surgery milieu increasingly focused on minimally invasive approaches.

    Relapse remains a significant problem in patients with metastatic osteosarcoma. The response to carboplatin of patients with newly diagnosed metastatic or unresectable osteosarcoma was assessed in an upfront phase II window, which was followed-up by surgery and intensive multiagent chemotherapy. Thirty-seven patients, ages 3 to 23 years with histologically confirmed diagnoses of osteosarcoma, were treated between January 1992 and November 1994 with carboplatin 1,000 mg/m2 per dose administered as a 48-hour continuous infusion. Two courses were administered in 3-week intervals, depending on marrow recovery. After radiographic reevaluation, patients underwent surgical removal of tumor (if feasible) and then 40 weeks of chemotherapy with high-dose methotrexate, ifosfamide, doxorubicin, and cisplatin. One of the 37 evaluable patients demonstrated a partial response to carboplatin; there were no complete responses. Patients were additionally analyzed by the response of pulmonary metastases to therapy and the extent of tumor necrosis of the primary lesion. By these criteria, 8 of 37 (22%) of patients showed a response at one or more sites, whereas 20 of 37 (54%) had unequivocal disease progression. Severe myelosuppression was the major toxicity. The projected 3-year event-free and overall survival rates were 23.9% and 31.9%, respectively. Only 1 of 17 patients with unresectable disease or distant bone metastases remains alive, in contrast to 6 of 17 patients with the lung as their only metastatic site and two of three patients with resected regional bone metastases. Continuous-infusion carboplatin demonstrated limited activity as an upfront agent in patients with metastatic osteosarcoma at diagnosis, even at doses that result in severe and prolonged myelosuppression. Patients with isolated pulmonary metastases or resectable bone metastases have a longer median survival time and greater chance of long-term survival than do patients with unresectable bone disease, for whom

    2016-01-01

    Oncology care is becoming increasingly complex. The interprofessional team concept of care is necessary to meet projected oncology professional shortages, as well as to provide superior oncology care. The oncology advanced practitioner (AP) is a licensed health care professional who has completed advanced training in nursing or pharmacy or has completed training as a physician assistant. Oncology APs increase practice productivity and efficiency. Proven to be cost effective, APs may perform varied roles in an oncology practice. Integrating an AP into an oncology practice requires forethought given to the type of collaborative model desired, role expectations, scheduling, training, and mentoring.

    Prompt identification and treatment of life-threatening oncological conditions is of utmost importance and should always be included in the differential diagnosis. Oncological emergencies can have a myriad of presentations ranging from mechanical obstruction due to tumor growth to metabolic conditions due to abnormal secretions from the tumor. Notably, hematologic and infectious conditions may complicate the presentation of oncological emergencies. Advanced testing and imaging is generally required to recognize these serious presentations of common malignancies. Early diagnosis and treatment of these conditions can significantly affect the patient's clinical outcome.

  18. Decision making in surgical oncology.

    2011-09-01

    Decisions in surgical oncology are increasingly being made by multi-disciplinary teams (MDTs). Although MDTs have been widely accepted as the preferred model for cancer service delivery, the process of decision making has not been well described and there is little evidence pointing to the ideal structure of an MDT. Performance in surgery has been shown to depend on non-technical skills, such as decision making, as well as patient factors and the technical skills of the healthcare team. Application of this systems approach to MDT working allows the identification of factors that affect the quality of decision making for cancer patients. In this article we review the literature on decision making in surgical oncology and by drawing from the systems approach to surgical performance we provide a framework for understanding the process of decision making in MDTs. Technical factors that affect decision making include the information about patients, robust ICT and video-conferencing equipment, a minimum dataset with expert review of radiological and pathological information, implementation and recording of the MDTs decision. Non-technical factors with an impact on decision making include attendance of team members at meetings, leadership, teamwork, open discussion, consensus on decisions and communication with patients and primary care. Optimising these factors will strengthen the decision making process and raise the quality of care for cancer patients.

    This review article, the second in a series of articles to examine the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Guidelines for the Use of Parenteral and Enteral Nutrition in Adult and Pediatric Patients, evaluates the evidence related to the use of nutrition support in surgical oncology patients. Cancer patients develop complex nutrition issues. Nutrition support may be indicated in malnourished cancer patients undergoing surgery, depending on individual patient characteristics. As with the first article in this series, this article provides background concerning nutrition issues in cancer patients, as well as discusses the role of nutrition support in the care of surgical cancer patients. The goal of this review is to enrich the discussion contained in the clinical guidelines as they relate to recommendations made for surgical patients, cite the primary literature more completely, and suggest updates to the guideline statements in light of subsequently published studies.

    The validation of the sentinel node concept in oncology has led to the rediscovery of lymphoscintigraphy. By combining preoperative lymphatic mapping with intraoperative probe detection this nuclear medicine procedure is being increasingly used to identify and detect the sentinel node in melanoma, breast cancer, and in other malignancies such as penile cancer and vulvar cancer. In the past lymphoscintigraphy has been widely applied for various indications in oncology, and in the case of the internal mammary lymph-node chain its current use in breast cancer remains essential to adjust irradiation treatment to the individual findings of each patient. In another diagnostic area, lymphoscintigraphy is also useful to document altered drainage patterns after surgery and/or radiotherapy; its use in breast cancer patients with upper limb oedema after axillary lymph-node dissection or in melanoma patients with lower-extremity oedema after groin dissection can provide information for physiotherapy or reconstructive surgery. Finally, the renewed interest in lymphoscintigraphy in oncology has led not only to the rediscovery of findings from old literature reports, but also to a discussion about methodological aspects such as tracer characteristics, image acquisition or administration routes, as well as to discussion on the study of migration patterns of radiolabelled colloid particles in the context of cancer dissemination. All this makes the need for standardized guidelines for lymphoscintigraphy mandatory. (orig.) With 10 figs., 1 tab., 56 refs.

    2014-05-01

    In medical oncology, how can we be sure that the right drug is being administered to the right patient at the right time? The implementation of quality assurance criteria is important in medical oncology, in order to ensure that the patient receives the best treatment safely. There is very little literature about quality assurance in medical oncology, as opposed to radiotherapy or cancer surgery. Quality assurance must cover the entire patient care process, from the diagnosis, to the therapeutic decision and drug distribution, including its selection, its preparation and its delivery to the patient (administration and dosage), and finally the potential side effects and their management. The dose-intensity respect is crucial, and its reduction can negatively affect overall survival rates, as shown in breast and testis cancers for example. In head and neck medical oncology, it is essential to respect the few well-standardized recommendations and the dose-intensity, in a population with numerous comorbidities. We will first review quality assurance criteria for the general medical oncology organization and then focus on head and neck medical oncology. We will then describe administration specificities of head and neck treatments (chemoradiation, radiation plus cetuximab, postoperative chemoradiation, induction and palliative chemotherapy) as well as their follow-up. Lastly, we will offer some recommendations to improve quality assurance in head and neck medical oncology.

    The value of comparative oncology has been increasingly recognized in the field of cancer research, including the identification of cancer-associated genes; the study of environmental risk factors, tumor biology, and progression; and, perhaps most importantly, the evaluation of novel cancer therapeutics. The fruits of this effort are expected to be the creation of better and more specific drugs to benefit veterinary and human patients who have cancer. The state of the comparative oncology field is outlined in this article, with an emphasis on cancer in dogs.

    Our purpose was to assess comparative female representation trends for trainees and full-time faculty in the academic radiation oncology and hematology oncology workforce of the United States over 3 decades. Simple linear regression models with year as the independent variable were used to determine changes in female percentage representation per year and associated 95% confidence intervals for trainees and full-time faculty in each specialty. Peak representation was 48.4% (801/1654) in 2013 for hematology oncology trainees, 39.0% (585/1499) in 2014 for hematology oncology full-time faculty, 34.8% (202/581) in 2007 for radiation oncology trainees, and 27.7% (439/1584) in 2015 for radiation oncology full-time faculty. Representation significantly increased for trainees and full-time faculty in both specialties at approximately 1% per year for hematology oncology trainees and full-time faculty and 0.3% per year for radiation oncology trainees and full-time faculty. Compared with radiation oncology, the rates were 3.84 and 2.94 times greater for hematology oncology trainees and full-time faculty, respectively. Despite increased female trainee and full-time faculty representation over time in the academic oncology physician workforce, radiation oncology is lagging behind hematology oncology, with trainees declining in recent years in radiation oncology; this suggests a de facto ceiling in female representation. Whether such issues as delayed or insufficient exposure, inadequate mentorship, or specialty competitiveness disparately affect female representation in radiation oncology compared to hematology oncology are underexplored and require continued investigation to ensure that the future oncologic physician workforce reflects the diversity of the population it serves.

    The movement to improve healthcare quality has led to a need for carefully designed quality indicators that accurately reflect the quality of care. Many different measures have been proposed and continue to be developed by governmental agencies and accrediting bodies. However, given the inherent differences in the delivery of care among medical specialties, the same indicators will not be valid across all of them. Specifically, oncology is a field in which it can be difficult to develop quality indicators, because the effectiveness of an oncologic intervention is often not immediately apparent, and the multidisciplinary nature of the field necessarily involves many different specialties. Existing and emerging comparative effectiveness data are helping to guide evidence-based practice, and the increasing availability of these data provides the opportunity to identify key structure and process measures that predict for quality outcomes. The increasing emphasis on quality and efficiency will continue to compel the medical profession to identify appropriate quality measures to facilitate quality improvement efforts and to guide accreditation, credentialing, and reimbursement. Given the wide-reaching implications of quality metrics, it is essential that they be developed and implemented with scientific rigor. The aims of the present report were to review the current state of quality assessment in oncology, identify existing indicators with the best evidence to support their implementation, and propose a framework for identifying and refining measures most indicative of true quality in oncologic care.

    Nanomedicine is an interdisciplinary field that combines medicine, engineering, chemistry, biology and material sciences to improve disease management and can be especially valuable in oncology. Nanoparticle-based agents that possess functions such as tumor targeting, imaging and therapy are currently under intensive investigation. This review introduces the basic concept of nanomedicine and the classification of nanoparticles. Because of their favorable pharmacokinetics, tumor targeting properties, and resulting superior efficacy and toxicity profiles, nanoparticle-based agents can overcome several limitations associated with conventional diagnostic and therapeutic protocols in veterinary oncology. The two most important tumor targeting mechanisms (passive and active tumor targeting) and their dominating factors (i.e. shape, charge, size and nanoparticle surface display) are discussed. The review summarizes published clinical and preclinical studies that utilize different nanoformulations in veterinary oncology, as well as the application of nanoparticles for cancer diagnosis and imaging. The toxicology of various nanoformulations is also considered. Given the benefits of nanoformulations demonstrated in human medicine, nanoformulated drugs are likely to gain more traction in veterinary oncology.

Examines technological issues and probe design. Discusses preclinical studies in detail, with particular attention to multimodality imaging. Presents current clinical use of PET/CT, SPECT/CT, and optical imagingWritten by acknowledged experts. The impact of molecular imaging on diagnostics, therapy, and follow-up in oncology is increasing significantly. The process of molecular imaging includes key biotarget identification, design of specific molecular imaging probes, and their preclinical evaluation, e.g., in vivo using small animal studies. A multitude of such innovative molecular imaging probes have already entered clinical diagnostics in oncology. There is no doubt that in future the emphasis will be on multimodality imaging in which morphological, functional, and molecular imaging techniques are combined in a single clinical investigation that will optimize diagnostic processes. This handbook addresses all aspects of molecular imaging in oncology, ranging from basic research to clinical applications in the era of evidence-based medicine. The first section is devoted to technology and probe design, and examines a variety of PET and SPECT tracers as well as multimodality probes. Preclinical studies are then discussed in detail, with particular attention to multimodality imaging. In the third section, diverse clinical applications are presented, and the book closes by looking at future challenges. This handbook will be of value to all who are interested in the revolution in diagnostic oncology that is being brought about by molecular imaging.

    Purpose: To test the hypothesis that medical student radiation oncology elective rotation grades are inflated and cannot be used to distinguish residency applicants. Methods and Materials: The records of 196 applicants to a single radiation oncology residency program in 2011 and 2012 were retrospectively reviewed. The grades for each rotation in radiation oncology were collected and converted to a standardized 4-point grading scale (honors, high pass, pass, fail). Pass/fail grades were scored as not applicable. The primary study endpoint was to compare the distribution of applicants' grades in radiation oncology with their grades in medicine, surgery, pediatrics, and obstetrics/gynecology core clerkships. Results: The mean United States Medical Licensing Examination Step 1 score of the applicants was 237 (range, 188-269), 43% had additional Masters or PhD degrees, and 74% had at least 1 publication. Twenty-nine applicants were graded for radiation oncology rotations on a pass/fail basis and were excluded from the final analysis. Of the remaining applicants (n=167), 80% received the highest possible grade for their radiation oncology rotations. Grades in radiation oncology were significantly higher than each of the other 4 clerkships studied (P<.001). Of all applicants, 195 of 196 matched into a radiation oncology residency. Higher grades in radiation oncology were associated with significantly higher grades in the pediatrics core clerkship (P=.002). However, other medical school performance metrics were not significantly associated with higher grades in radiation oncology. Conclusions: Although our study group consists of a selected group of radiation oncology applicants, their grades in radiation oncology clerkships were highly skewed toward the highest grades when compared with grades in other core clerkships. Student grading in radiation oncology clerkships should be re-evaluated to incorporate more objective and detailed performance metrics to allow for

    Deng, Gary; Cassileth, Barrie

    2014-01-01

    Integrative oncology, the diagnosis-specific field of integrative medicine, addresses symptom control with nonpharmacologic therapies. Known commonly as "complementary therapies" these are evidence-based adjuncts to mainstream care that effectively control physical and emotional symptoms, enhance physical and emotional strength, and provide patients with skills enabling them to help themselves throughout and following mainstream cancer treatment. Integrative or complementary therapies are rational and noninvasive. They have been subjected to study to determine their value, to document the problems they ameliorate, and to define the circumstances under which such therapies are beneficial. Conversely, "alternative" therapies typically are promoted literally as such; as actual antitumor treatments. They lack biologic plausibility and scientific evidence of safety and efficacy. Many are outright fraudulent. Conflating these two very different categories by use of the convenient acronym "CAM," for "complementary and alternative therapies," confuses the issue and does a substantial disservice to patients and medical professionals. Complementary and integrative modalities have demonstrated safety value and benefits. If the same were true for "alternatives," they would not be "alternatives." Rather, they would become part of mainstream cancer care. This manuscript explores the medical and sociocultural context of interest in integrative oncology as well as in "alternative" therapies, reviews commonly-asked patient questions, summarizes research results in both categories, and offers recommendations to help guide patients and family members through what is often a difficult maze. Combining complementary therapies with mainstream oncology care to address patients' physical, psychologic and spiritual needs constitutes the practice of integrative oncology. By recommending nonpharmacologic modalities that reduce symptom burden and improve quality of life, physicians also enable

    Full Text Available Neurologic side effects related to cancer therapy are a common problem in oncology practice. These complications can negatively affect the management of the patient, because they can inhibit treatment and diminish quality of life. Therefore specific skills are required to recognise symptoms and clinical manifestations. This review focuses on the most common neurologic complications to improve physician’s familiarity in determining the aetiology of these symptoms.

    There are many radiological interventions necessary for pediatric oncology patients, some of which may be covered in other articles in this publication. I will discuss a number of interventions including percutaneous biopsy for solid tumor and hematological malignancy diagnosis or recurrence, for the diagnosis of graft versus host disease after stem cell or bone marrow transplantation, and for the diagnosis of complications of immunosuppression such as invasive pulmonary aspergillosis. In the past, tumor localization techniques have been necessary to biopsy or resect small lesions. However improved guidance techniques have allowed for more precise biopsy and the use of thermal ablation instead of excision for local tumor control. A percutaneously placed radio frequency, microwave, laser or cryogen probe can ablate the primary and metastatic tumors of the liver, lung, bone, kidney and other structures in children. This is an alternative treatment for the local control of tumors that may not be amenable to surgery, chemotherapy or radiotherapy. I will also describe how chemoembolization can be used to treat primary or metastatic tumors of the liver that have failed other therapies. This treatment delivers chemotherapy in the hepatic artery infused with emboli to increase the dwell time and concentration of the agents.

    Minimally invasive surgery has revolutionized gynecological interventions over the past 30 years. The introduction of the da Vinci robotic surgery in 2005 has resulted in large changes in surgical management. The robotic platform allows less experienced laparoscopic surgeons to perform more complex procedures. It can be utilized mainly in general gynecology and reproductive gynecology. The robot is being increasingly used for procedures such as hysterectomy, myomectomy, adnexal surgery, and tubal anastomosis. In urogynecology, the robot is being utilized for sacrocolopexy as well. In the field of gynecologic oncology, the robot is being increasingly used for hysterectomy and lymphadenectomy in oncologic diseases. Despite the rapid and widespread adaption of robotic surgery in gynecology, there are no randomized trials comparing its efficacy and safety to other traditional surgical approaches. This article presents the development, technical aspects and indications of robotic surgery in gynecology, based on the previously published reviews. Robotic surgery can be highly advantageous with the right amount of training, along with appropriate patient selection. Patients will have less blood loss, less post-operative pain, faster recovery, and fewer complications compared to open surgery and laparoscopy. However, until larger randomized control trials are completed which report long-term outcomes, robotic surgery cannot be stated to have priority over other surgical methods.

    Oncologic specialty societies and multidisciplinary collaborative groups have dedicated considerable effort to developing evidence-based quality indicators (QIs) to facilitate quality improvement, accreditation, benchmarking, reimbursement, maintenance of certification, and regulatory reporting. In particular, the field of radiation oncology has a long history of organized quality assessment efforts and continues to work toward developing consensus quality standards in the face of continually evolving technologies and standards of care. This report provides a comprehensive review of the current state of quality assessment in radiation oncology. Specifically, this report highlights implications of the healthcare quality movement for radiation oncology and reviews existing efforts to define and measure quality in the field, with focus on dimensions of quality specific to radiation oncology within the “big picture” of oncologic quality assessment efforts.

    In The Netherlands, since September 2003, a legal medicinal cannabis product, constituting the whole range of cannabinoids, is available for clinical research, drug development strategies, and on prescription for patients. To date, this policy, initiated by the Dutch Government, has not yet led to the desired outcome; the amount of initiated clinical research is less than expected and only a minority of patients resorts to the legal product. This review aims to discuss the background for the introduction of legal medicinal cannabis in The Netherlands, the past years of Dutch clinical experience in oncology practice, possible reasons underlying the current outcome, and future perspectives.

    Cambodia, a country of 14 million inhabitants, was devastated during the Khmer Rouge period and thereafter. The resources of treatment are rare: only one radiotherapy department, renovated in 2003, with an old cobalt machine; few surgeons trained to operate on cancer patients; no hematology; no facilities to use intensive chemotherapy; no nuclear medicine department and no palliative care unit. Cervical cancer incidence is one of the highest in the world, while in men liver cancer ranks first (20% of all male cancers). Cancers are seen at stage 3 or 4 for 70% of patients. There is no prevention program - only a vaccination program against hepatitis B for newborns - and no screening program for cervical cancer or breast cancer. In 2010, oncology, recognized as a full specialty, was created to train the future oncologists on site at the University of Phnom Penh. A new National Cancer Center will be built in 2013 with modern facilities for radiotherapy, medical oncology, hematology and nuclear medicine. Cooperation with foreign countries, especially France, and international organizations has been established and is ongoing. Progress is occurring slowly due to the shortage of money for Cambodian institutions and the lay public.

    This book concisely reviews our current understanding of hypoxia, molecular targeting, DNA repair, cancer stem cells, and tumor pathophysiology, while also discussing novel strategies for putting these findings into practice in daily clinical routine. Radiotherapy is an important part of modern multimodal cancer treatment, and the past several years have witnessed not only substantial improvements in radiation techniques and the use of new beam qualities, but also major strides in our understanding of molecular tumor biology and tumor radiation response. Against this backdrop, the book highlights recent efforts to identify reasonable and clinically applicable biomarkers using broad-spectrum tissue microarrays and high-throughput systems biology approaches like genomics and epigenomics. In particular, it describes in detail how such molecular information is now being exploited for diagnostic imaging and imaging throughout treatment using the example of positron emission tomography. By discussing all these issues in the context of modern radiation oncology, the book provides a broad, up-to-date overview of the molecular aspects of radiation oncology that will hopefully foster its further optimization.

Several treatment modalities, such as surgery, glycolytic inhibition, driving CSC proliferation, immunotherapy, and hypofractionated radiotherapy, may have the potential to eradicate CSCs. We propose that monitoring CSCs is important in clinical oncology as CSC populations may reflect true treatment response and assist with managing treatment strategies, such as defining optimal chemotherapy cycles, permitting pretreatment cancer surveillance, conducting a comprehensive treatment plan, modifying radiation treatment, and deploying rechallenge chemotherapy. Then, we describe methods for monitoring CSCs. Keywords: cancer stem cells, glycolytic inhibition, watchful waiting, rechallenge, immunotherapy

    The Canadian Association of Nurses in Oncology (CANO) Standards of Care (2001) provides a framework that delineates oncology nursing roles and responsibilities. The purpose of this study was to explore how oncology nurses perceive their roles and responsibilities compared to the CANO Standards of Care. Six focus groups were conducted and 21 registered nurses (RNs) from a community-based hospital participated in this study. Transcripts were analyzed using qualitative inductive content analysis. Three themes were identified: (1) Oncology nurses perceive a gap between their defined roles and the reality of daily practice, as cancer care becomes more complex and as they provide advanced oncology care to more patients while there is no parallel adaptation to the health care system to support them, such as safe staffing; (2) Oncology nursing, as a specialty, requires sustained professional development and leadership roles; and (3) Oncology nurses are committed to providing continuous care as a reference point in the health care team by fostering interdisciplinary collaboration andfacilitating patient's navigation through the system. Organizational support through commitment to appropriate staffing and matching scope ofpractice to patient needs may lead to maximize the health and well-being of nurses, quality of patient care and organizational performance.

    With chapters on free boundaries, constitutive equations, stochastic dynamics, nonlinear diffusion–consumption, structured populations, and applications of optimal control theory, this volume presents the most significant recent results in the field of mathematical oncology. It highlights the work of world-class research teams, and explores how different researchers approach the same problem in various ways. Tumors are complex entities that present numerous challenges to the mathematical modeler. First and foremost, they grow. Thus their spatial mean field description involves a free boundary problem. Second, their interiors should be modeled as nontrivial porous media using constitutive equations. Third, at the end of anti-cancer therapy, a small number of malignant cells remain, making the post-treatment dynamics inherently stochastic. Fourth, the growth parameters of macroscopic tumors are non-constant, as are the parameters of anti-tumor therapies. Changes in these parameters may induce phenomena that a...

    National insurance companies in Germany support health cures for patients with malignant tumors (malignant melanoma, squamous cell carcinoma, Merkel cell tumor, malignant cutaneous lymphoma). The clinical requirements are an invasively growing tumor, problems of self-assurance, and dis-integration of the patient regarding his social and/or professional environment. The decision for a health cure is made by the treating dermatologist in the hospital. In this context, the following sociomedical criteria should be applied: impairment, disability, and handicap. Usually, rehabilitation starts after the patient is discharged from the hospital. The inpatient rehabilitation program should be performed at an institution capable of providing dermatological and psychological treatment. The dermatologist acts as a manager for the members of the rehabilitation team (psychologists, physiotherapists, social workers, and ergo-therapists). In conclusion, dermato-oncologic rehabilitation plays an important role in re-integrating the patient into his professional life to avoid retirement.

    Although robotic technology aims to obviate some of the limitations of conventional laparoscopic surgery, the role of robotics in colorectal surgery is still largely undefined and different with respect to its application in abdominal versus pelvic surgery. This review aims to elucidate current developments in colorectal robotic surgery.In colon surgery, robotic techniques are associated with longer operative times and higher costs compared with laparoscopic surgery. However, robotics provides a stable camera platform and articulated instruments that are not subject to human tremors. Because of these advantages, robotic systems can play a role in complex procedures such as the dissection of lymph nodes around major vessels. In addition robot-assisted hand-sewn intracorporeal anastomoses can be easily performed by the surgeon, without a substantial need for a competent assistant. At present, although the short-term outcomes and oncological adequacy of robotic colon resection have been observed to be acceptable, the long-term outcomes of robotic colon resection remain unknown.In rectal surgery, robotic-assisted surgery for rectal cancer can be carried out safely and in accordance with current oncological principles. However, to date, the impact of robotic rectal surgery on the long-term oncological outcomes of minimally invasive total mesorectal excision remains undetermined. Robotic total mesorectal excision may allow for better preservation of urinary and sexual functions, and robotic surgery may attenuate the learning curve for laparoscopic rectal resection. However, a major drawback to robotic rectal surgery is the high cost involved.Large-scale prospective randomized clinical trials such as the international randomized trial ROLARR are required to establish the benefits of robotic rectal surgery.

    Full Text Available Introduction. Plastic surgery is a medical specialty dealing with corrections of defects, improvements in appearance and restoration of lost function. Ancient Times. The first recorded account of reconstructive plastic surgery was found in ancient Indian Sanskrit texts, which described reconstructive surgeries of the nose and ears. In ancient Greece and Rome, many medicine men performed simple plastic cosmetic surgeries to repair damaged parts of the body caused by war mutilation, punishment or humiliation. In the Middle Ages, the development of all medical braches, including plastic surgery was hindered. New age. The interest in surgical reconstruction of mutilated body parts was renewed in the XVIII century by a great number of enthusiastic and charismatic surgeons, who mastered surgical disciplines and became true artists that created new forms. Modern Era. In the XX century, plastic surgery developed as a modern branch in medicine including many types of reconstructive surgery, hand, head and neck surgery, microsurgery and replantation, treatment of burns and their sequelae, and esthetic surgery. Contemporary and future plastic surgery will continue to evolve and improve with regenerative medicine and tissue engineering resulting in a lot of benefits to be gained by patients in reconstruction after body trauma, oncology amputation, and for congenital disfigurement and dysfunction.

    Neuro-oncology is a subspecialty attracting physicians from medical disciplines such as neurology, neurosurgery, pediatrics, oncology, and radiotherapy. It deals with diagnosis and management of primary brain tumors, as well as metastatic and non-metastatic neurological manifestations that frequently affect cancer patients including brain metastases, paraneoplastic syndromes and neurological complications of cancer treatment. A neuro-oncology unit was established in Davidoff Cancer Center at Rabin Medical Center. It provides a multidisciplinary team approach for management of brain tumors and services, such as expert outpatient clinics and inpatient consultations for the departments of oncology, hematology, bone marrow transplantation and other departments in the Rabin Medical Center. In addition, expert consultation is frequently provided to other hospitals that treat cancer patients with neurological manifestations. The medical disciplines that closely collaborate for the daily management of neuro-oncology patients include radiotherapy, hematology, oncology, neuro-surgery, neuro-radiology and neuro-pathology. The neuro-oncology center is also involved in clinical and laboratory research conducted in collaboration with researchers in Israel and abroad. The new service contributes substantially to the improved care of cancer patients and to the advance of research topics in the field of neuro-oncology.

    Purpose: A phase 2 study was completed by the Korean Gynecologic Oncologic Group to evaluate the efficacy and toxicity of concurrent chemoradiation with weekly paclitaxel in patients with high-risk endometrial cancer. Methods and Materials: Pathologic requirements included endometrial endometrioid adenocarcinoma stages III and IV. Radiation therapy consisted of a total dose of 4500 to 5040 cGy in 5 fractions per week for 6 weeks. Paclitaxel 60 mg/m{sup 2} was administered once weekly for 5 weeks during radiation therapy. Results: Fifty-seven patients were enrolled between January 2006 and March 2008. The median follow-up time was 60.0 months (95% confidence interval [CI], 51.0-58.2). All grade 3/4 toxicities were hematologic and usually self-limited. There was no life-threatening toxicity. The cumulative incidence of intrapelvic recurrence sites was 1.9% (1/52), and the cumulative incidence of extrapelvic recurrence sites was 34.6% (18/52). The estimated 5-year disease-free and overall survival rates were 63.5% (95% CI, 50.4-76.5) and 82.7% (95% CI, 72.4-92.9), respectively. Conclusions: Concurrent chemoradiation with weekly paclitaxel is well tolerated and seems to be effective for high-risk endometrioid endometrial cancers. This approach appears reasonable to be tested for efficacy in a prospective, randomized controlled study.

This has been associated with the increase in infection of the oropharynx by oncogenic strains of human papillomavirus (HPV. Transoral robotic surgery (TORS has opened the door for minimally invasive surgery for HPV-related and non-HPV-related oropharyngeal cancer. Compared to traditional open surgical approaches, TORS has been shown to improve functional outcomes in speech and swallowing, while maintaining good oncologic outcomes.

  15. Minimally Invasive Liver Surgery for Hepatic Colorectal Metastases.

    Science.gov (United States)

    Nassour, Ibrahim; Polanco, Patricio M

    2016-04-01

    Minimally invasive surgery has been cautiously introduced in surgical oncology over the last two decades due to a concern of compromised oncological outcomes. Recently, it has been adopted in liver surgery for colorectal metastases. Colorectal cancer is a major cause of cancer-related death in the USA. In addition, liver metastasis is the most common site of distant disease and its resection improves survival. While open resection was the standard of care, laparoscopic liver surgery has become the standard of care for minor liver resections. Laparoscopic liver surgery provides equivalent oncological outcomes with better perioperative results compared to open liver surgery. Robotic liver surgery has been introduced as it is believed to overcome some of the limitations of laparoscopy. Finally, laparoscopic radio-frequency ablation and microwave coagulation can be used as adjuncts in minimally invasive surgery to complement or replace surgical resection when not possible.

    Endoscopic examinations provide a valuable, noninvasive adjunct in the diagnosis and staging of many neoplastic disorders (Table 1). Additionally, the clinical applications of endoscopic-guided laser or photodynamic therapy have yet to be investigated thoroughly in companion animals. Endoscopy does not eliminate the need for other diagnostics, rather it should be considered complementary to more "traditional" procedures such as radiography, surgery, and ultrasonography.

    1984-09-08

    As in some other chronic diseases (rheumatism, multiple sclerosis, etc.), unproven methods of diagnosis and treatment have long been current in cancer. Since 1960 the American Cancer Society has published an abundant literature on these "unproven methods", which serves as a basis for a historical review: some substances (Krebiozen, Laetrile) have enjoyed tremendous if shortlived success. The present trend is back to nature and "mild medicine". The proponents of this so-called natural medicine are often disciples of a pseudoscientific religion using irrational arguments. Direct attacks on these erroneous theories and their public refutation fail to convince the adepts, who trust in these methods and are not amenable to a scientific approach. Study of their psychological motivations reveals that in fact they seek something more reassuring than plain medical explanation which is aware of its limits. They feel reassured by theories which often bear some resemblance to the old popular medicine. To protect patients against these dangerous methods and all the disillusionment they entail, the Swiss Society of Oncology and the Swiss Cancer League have decided to gather information and draw up a descriptive list of the commonest unproven methods in Switzerland (our File No. 2, "Total anti-cancer cure", is given as an example). The files are published in French, German and English and are available to physicians, nursing teams, and also patients who wish to have more objective information on these methods.

  18. [Economic limits in oncology].

    Science.gov (United States)

    Hellriegel, K P

    2000-12-01

    Economic aspects require consideration even in oncology. However, they have to be seen in context with open questions concerning especially the evaluation of therapeutic effectiveness, of methodology, and particularly of ethics. Medical procedures and achievements should primarily be measured against objective results, against effectiveness and benefits. Consequently, the suitability of diagnostic and therapeutic strategies has to be evaluated. Overall objective of medical achievements should be their optimalization, not their maximization. For a physician being aware of his responsibility, the optimal care for his patients always has highest priority. Medical guidelines for diagnosis, treatment and follow-up are the basis for effective and economic patient care. They have to undergo economic evaluation and permanent updating. For systematic collection, documentation and evaluation, the clinical register is the appropriate instrument. For the assessment of medical care, a continuous monitoring of its processes has to be established. The documentation of medical care processes should lead to sustainable cost reductions together with an optimalization of the quality of care.

  19. Micronutrients in Oncological Intervention

    Directory of Open Access Journals (Sweden)

    Uwe Gröber

    2016-03-01

    Full Text Available Nutritional supplements are widely used among patients with cancer who perceive them to be anticancer and antitoxicity agents. Depending on the type of malignancy and the gender 30%–90% of the cancer patients supplement their diets with antioxidant and immuno-stabilizing micronutrients, such as selenium, vitamin C, and vitamin D, often without the knowledge of the treating physician. From the oncological viewpoint, there are justifiable concerns that dietary supplements decrease the effectiveness of chemotherapy and radiotherapy. Recent studies, however, have provided increasing evidence that treatment is tolerated better—with an increase in patient compliance and a lower rate of treatment discontinuations—when micronutrients, such as selenium, are added as appropriate to the patient’s medication. Nutritional supplementation tailored to an individual’s background diet, genetics, tumor histology, and treatments may yield benefits in subsets of patients. Clinicians should have an open dialogue with patients about nutritional supplements. Supplement advice needs to be individualized and come from a credible source, and it is best communicated by the physician.

    The objective of this study was to provide a descriptive analysis of registered clinical trials in surgical oncology at ClinicalTrials.gov. Data was extracted from ClinicalTrials.gov using the following search engine criteria: "Cancer" as Condition, "Surgery OR Operation OR Resection" as Intervention, and Non-Industry sponsored. The search was limited to Canada and the United States and included trials registered from January 1, 2001 to January 1, 2011. Of 9,961 oncology trials, 1,049 (10.5%) included any type of surgical intervention. Of these trials, 125 (11.9%, 1.3% of all oncology trials) assessed a surgical variable, 773 (73.7%) assessed adjuvant/neoadjuvant therapies, and 151 (14.4%) were observational studies. Of the trials assessing adjuvant therapies, systemic treatment (362 trials, 46.8%) and multimodal therapy (129 trials, 16.7%) comprised a large focus. Of the 125 trials where surgery was the intervention, 59 trials (47.2%) focused on surgical techniques or devices, 45 trials (36.0%) studied invasive diagnostic methods, and 21 trials (16.8%) evaluated surgery versus no surgery. The majority of the 125 trials were nonrandomized (72, 57.6%). The number of registered surgical oncology trials is small in comparison to oncology trials as a whole. Clinical trials specifically designed to assess surgical interventions are vastly outnumbered by trials focusing on adjuvant therapies. Randomized surgical oncology trials account for <1% of all registered cancer trials. Barriers to the design and implementation of randomized trials in surgical oncology need to be clarified in order to facilitate higher-level evidence in surgical decision-making.

    2015-01-01

    This paper aims to identify the key fields and their key technical points of oncology by patent analysis. Patents of oncology applied from 2006 to 2012 were searched in the Thomson Innovation database. The key fields and their key technical points were determined by analyzing the Derwent Classification (DC) and the International Patent Classification (IPC), respectively. Patent applications in the top ten DC occupied 80% of all the patent applications of oncology, which were the ten fields of oncology to be analyzed. The number of patent applications in these ten fields of oncology was standardized based on patent applications of oncology from 2006 to 2012. For each field, standardization was conducted separately for each of the seven years (2006-2012) and the mean of the seven standardized values was calculated to reflect the relative amount of patent applications in that field; meanwhile, regression analysis using time (year) and the standardized values of patent applications in seven years (2006-2012) was conducted so as to evaluate the trend of patent applications in each field. Two-dimensional quadrant analysis, together with the professional knowledge of oncology, was taken into consideration in determining the key fields of oncology. The fields located in the quadrant with high relative amount or increasing trend of patent applications are identified as key ones. By using the same method, the key technical points in each key field were identified. Altogether 116,820 patents of oncology applied from 2006 to 2012 were retrieved, and four key fields with twenty-nine key technical points were identified, including "natural products and polymers" with nine key technical points, "fermentation industry" with twelve ones, "electrical medical equipment" with four ones, and "diagnosis, surgery" with four ones. The results of this study could provide guidance on the development direction of oncology, and also help researchers broaden innovative ideas and discover new

    Full Text Available This paper aims to identify the key fields and their key technical points of oncology by patent analysis.Patents of oncology applied from 2006 to 2012 were searched in the Thomson Innovation database. The key fields and their key technical points were determined by analyzing the Derwent Classification (DC and the International Patent Classification (IPC, respectively. Patent applications in the top ten DC occupied 80% of all the patent applications of oncology, which were the ten fields of oncology to be analyzed. The number of patent applications in these ten fields of oncology was standardized based on patent applications of oncology from 2006 to 2012. For each field, standardization was conducted separately for each of the seven years (2006-2012 and the mean of the seven standardized values was calculated to reflect the relative amount of patent applications in that field; meanwhile, regression analysis using time (year and the standardized values of patent applications in seven years (2006-2012 was conducted so as to evaluate the trend of patent applications in each field. Two-dimensional quadrant analysis, together with the professional knowledge of oncology, was taken into consideration in determining the key fields of oncology. The fields located in the quadrant with high relative amount or increasing trend of patent applications are identified as key ones. By using the same method, the key technical points in each key field were identified. Altogether 116,820 patents of oncology applied from 2006 to 2012 were retrieved, and four key fields with twenty-nine key technical points were identified, including "natural products and polymers" with nine key technical points, "fermentation industry" with twelve ones, "electrical medical equipment" with four ones, and "diagnosis, surgery" with four ones.The results of this study could provide guidance on the development direction of oncology, and also help researchers broaden innovative ideas and

    Laparoscopic techniques have been extensively used for the surgical management of colorectal cancer during the last two decades. Accumulating data have demonstrated that laparoscopic colectomy is associated with better short-term outcomes and equivalent oncologic outcomes when compared with open surgery. However, some controversies regarding the oncologic quality of mini-invasive surgery for rectal cancer exist. Meanwhile, some progresses in colorectal surgery, such as robotic technology, single-incision laparoscopic surgery, natural orifice specimen extraction, and natural orifice transluminal endoscopic surgery, have been made in recent years. In this article, we review the published data and mainly focus on the current status and latest advances of mini-invasive surgery for colorectal cancer.

    Cancer treatments in veterinary medicine continue to evolve beyond the established standard therapies of surgery, chemotherapy and radiation therapy. New technologies in cancer therapy include a targeted mechanism to open the cell membrane based on electroporation, driving therapeutic agents, such as chemotherapy (electro-chemotherapy), for local control of cancer, or delivery of gene-based products (electro-gene therapy), directly into the cancer cell to achieve systemic control. This review examines electrochemotherapy and electro-gene therapy in veterinary medicine and considers future directions and applications. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The use of chemotherapy and radiotherapy in oncological patients may reduce their reproductive potential. Sperm cryopreservation has been already used in men affected by neoplastic disease. Oocyte cryopreservation might be an important solution for these patients at risk of losing ovarian function. A program of oocyte cryopreservation for oncological patients is also present in our center. From June 1996 to January 2000, 18 patients awaiting chemotherapy and radiotherapy for neoplastic disease were included in our oocyte cryopreservation program. Our experience documents that oocyte storage may be a concrete and pragmatic alternative for oncological patients. The duration of oocyte storage does not seem to interfere with oocyte survival as pregnancies occurred even after several years of gamete cryopreservation in liquid nitrogen.

    1993-12-01

    Personality type influences the choice of occupation. The breadth of specialty areas within oncology nursing allows for divergent activities and relationships and, thus, the accommodation of different personality characteristics. This exploratory study examined personality types for a convenience sample of oncology nurses predominantly employed in hospitals. According to the personality typology defined by Carl Jung, a person demonstrates a preference among four dimensions, i.e., extraversion/introversion, sensory/intuition, thinking/feeling, and judging/perceiving. The type with the strongest self-selection for these oncology nurses was ISFJ, where feeling is introverted and perception is practical, so that helping others is both a responsibility and a pleasure. The discussion relates the personality types to Jung's theory and their impact in clinical practice. Strengths and weaknesses of each personality type are described.

  10. Palliative medicine and medical oncology.

    2001-04-01

    Traditionally, medical oncology and palliative care have been considered two distinct and separate disciplines, both as regards treatment objectives and delivery times. Palliative care in terminal stages, aimed exclusively at evaluating and improving quality of life, followed antitumor therapies, which concentrated solely on quantitative results (cure, prolongation of life, tumoral mass shrinkage). Over the years, more modern concepts have developed on the subject. Medical oncology, dealing with the skills and strategic co-ordination of oncologic interventions from primary prevention to terminal phases, should also include assessment and treatment of patients' subjective needs. Anticancer therapies should be evaluated in terms of both the quantitative and qualititative impact on patients' lives. Hence, the traditional view of palliative care has to be modified: it constitutes a philosophical and methodological approach to be adopted from the early phases of illness. It is not the evident cultural necessity of integrating medical oncology with palliative medicine that may be a matter of argument, but rather the organizational models needed to put this combined care into practice: should continuous care be guaranteed by a single figure, the medical oncologist, or rather by an interdisciplinary providers' team, including full-time doctors well-equipped for palliative care? In this paper the needs of cancer patients and the part that a complete oncologist should play to deal with such difficult and far-reaching problems are firstly described. Then, as mild provocation, data and critical considerations on the ever increasing needs of palliative care, the present shortcomings in quality of life and pain assessment and management by medical oncologists, and the uncertain efficacy of interventional programmes to change clinical practice are described. Finally, a model of therapeutic continuity is presented. which in our view is realistic and feasible: an Oncologic

    To identify ways to improve cancer care for older patients, we set out to examine how older patients in the Netherlands are currently being evaluated prior to oncological treatment and to explore the potential obstacles in the incorporation of a geriatric evaluation, using a web-based survey sent to Dutch medical oncology specialists and oncology nursing specialists. The response rate was 34% (183 out of 544). Two-thirds of respondents reported that a geriatric evaluation was being used, although primarily on an ad hoc basis only. Most respondents expressed a desire for a routine evaluation or more intensive collaboration with the geriatrician and 86% of respondents who were not using a geriatric evaluation expressed their interest to do so. The most important obstacles were a lack of time or personnel and insufficient availability of a geriatrician to perform the assessment. Thus, over 30% of oncology professionals in the Netherlands express an interest in geriatric oncology. Important obstacles to a routine implementation of a geriatric evaluation are a lack of time, or insufficient availability of geriatricians; this could be overcome with policies that acknowledge that quality cancer care for older patients requires the investment of time and personnel.

    Survival rate for childhood cancer has increased in recent years, reaching as high as 70% in developed countries compared with 54% for all cancers diagnosed in the 1980s. In the remaining 30%, progression or metastatic disease leads to death and in this framework palliative care has an outstanding role though not well settled in all its facets. In this landscape, surgery has a supportive actor role integrated with other welfare aspects from which are not severable. The definition of surgical palliation has moved from the ancient definition of noncurative surgery to a group of practices performed not to cure but to alleviate an organ dysfunction offering the best quality of life possible in all the aspects of life (pain, dysfunctions, caregivers, psychosocial, etc.). To emphasize this aspect a more modern definition has been introduced: palliative therapy in whose context is comprised not only the care assistance but also the plans of care since the onset of illness, teaching the matter to surgeons in training and share paths. Literature is very poor regarding surgical aspects specifically dedicated and all researches (PubMed, Google Scholar, and Cochrane) with various meshing terms result in a more oncologic and psychosocial effort.

    Purpose: To convene a multidisciplinary panel of breast experts to examine the relationship between margin width and ipsilateral breast tumor recurrence (IBTR) and develop a guideline for defining adequate margins in the setting of breast conserving surgery and adjuvant radiation therapy. Methods and Materials: A multidisciplinary consensus panel used a meta-analysis of margin width and IBTR from a systematic review of 33 studies including 28,162 patients as the primary evidence base for consensus. Results: Positive margins (ink on invasive carcinoma or ductal carcinoma in situ) are associated with a 2-fold increase in the risk of IBTR compared with negative margins. This increased risk is not mitigated by favorable biology, endocrine therapy, or a radiation boost. More widely clear margins than no ink on tumor do not significantly decrease the rate of IBTR compared with no ink on tumor. There is no evidence that more widely clear margins reduce IBTR for young patients or for those with unfavorable biology, lobular cancers, or cancers with an extensive intraductal component. Conclusions: The use of no ink on tumor as the standard for an adequate margin in invasive cancer in the era of multidisciplinary therapy is associated with low rates of IBTR and has the potential to decrease re-excision rates, improve cosmetic outcomes, and decrease health care costs.

Data obtained from high-throughput technologies are deepening our understanding about the molecular and gene network in cancer cells and rapidly emerging in vitro and in vivo evidence is highlighting the role of antisense agents as specific inhibitors of the expression of target genes, thus modulating the response of cancer cells to different therapeutic strategies. Much information is continuously being added into various facets of molecular oncology and it is now understood that overexpression of antiapoptotic proteins, oncogenes, oncogenic microRNAs (miRNA, and fusion proteins make cancer cells difficult to target. Delivery of antisense oligonucleotides has remained a challenge and technological developments have helped in overcoming hurdles by improving the ability to penetrate cells, effective and targeted binding to gene sequences, and downregulation of target gene function. Different delivery systems, including stable nucleic acid lipid particles, have shown potential in enhancing the delivery of cargo to the target site. In this review, we attempt to summarize the current progress in the development of antisense therapeutics and their potential in medical research. We partition this multicomponent

    Remarkably, although 60% of new cancer cases and over 70% of cancer deaths occur in patients aged 65 years and older in Europe, standard treatment strategies have been mostly validated in younger adults. This demographic trend has led to the emergence of a new medical discipline, geriatric oncology and the development worldwide of geriatric oncology programs for the individualized management of elderly cancer patients. Elderly cancer patients represent an increasing share of the population and strategies for treating cancer must evolve to face this ineluctable reality. Treatment should take into account the highly heterogeneous physiological age of the elderly, their individual life expectancy, functional reserves, social support and preferences. French geriatric oncology programs have been mostly based on the interdependence of geriatricians, oncologists and auxiliary nursing people. This approach represent the best way to offer patients optimal management; oncologists and geriatricians collaborate to assess both global health status by means of Comprehensive Geriatric Assessment (CGA) and tumor stage by means of Comprehensive Tumor Assessment (CTA) and to initiate individualized care plans, involving comprehensive management and follow-up of all identified problems. This paper focuses on progress observed in the field of geriatric oncology both in France and worldwide.

    The history of oncology in Slovakia is closely linked to the history of St. Elizabeth Hospital, which was set up in the mid-18th century by nuns of the St. Elizabeth Order in Bratislava. In the first half of the 20th century, a unit was set up in the hospital dedicated to diagnosis and treatment of cancer. Shortly after World War II, the unit was turned into the Institute for Cancer Research and Treatment. In 1950, St. Elizabeth Hospital was nationalized, and the Cancer Research Institute of the Slovak Academy of Science and the Institute of Clinical Oncology were located there as centers for oncological diagnosis and treatment. After the restitution of church property in the early 1990s, the hospital was returned to the Order of St. Elizabeth, which set up the St. Elisabeth Cancer Institute in the hospital premises in January of 1996. This year marks the 20th anniversary of this institute in its new premises and the 85th anniversary of the Institute of Radiumtherapy founded in Bratislava, and thus the establishment of institutional healthcare for cancer patients in Slovakia is the reason for balancing. We present a view of the consecutive changes in the organization, space and staff of the Institute and evaluate the impact of celebrities on medicine who developed oncology as a clinical, scientific and educational discipline in Bratislava and in other cities and regions of Slovakia.

  7. Chances, risks and limitations of neoadjuvant therapy in surgical oncology

    Directory of Open Access Journals (Sweden)

    Lordick Florian

    2016-09-01

    Full Text Available Over the last decades, neoadjuvant treatment has been established as a standard of care for a variety of tumor types in visceral oncology. Neoadjuvant treatment is recommended in locally advanced esophageal and gastric cancer as well as in rectal cancer. In borderline resectable pancreatic cancer, neoadjuvant therapy is an emerging treatment concept, whereas in resectable colorectal liver metastases, neoadjuvant treatment is often used, although the evidence for improvement of survival outcomes is rather weak. What makes neoadjuvant treatment attractive from a surgical oncology viewpoint is its ability to shrink tumors to a smaller size and to increase the chances for complete resection with clear surgical margins, which is a prerequisite for cure. Studies suggest that local tumor control is increased in some visceral tumor types, especially with neoadjuvant chemoradiotherapy. In some other studies, a better control of systemic disease has contributed to significantly improved survival rates. Additionally, delaying surgery offers the chance to bring the patient into a better general condition for major surgery, but it also confers the risk of progression. Although it is a relatively rare event, cancers may progress locally during neoadjuvant treatment or distant metastases may occur, jeopardizing a curative surgical treatment approach. Although this is seen as risk of neoadjuvant treatment, it can also be seen as a chance to select only those patients for surgery who have a better control of systemic disease. Some studies showed increased perioperative morbidity in patients who underwent neoadjuvant treatment, which is another potential disadvantage. Optimal multidisciplinary teamwork is key to controlling that risk. Meanwhile, the neoadjuvant treatment period is also used as a “window of opportunity” for studying the activity of novel drugs and for investigating predictive and prognostic biomarkers of chemoradiotherapy and radiochemotherapy

    Treatment of cancer involves a multidisciplinary approach consisting of surgery, chemotherapy, molecular targeted therapy and radiation therapy. These therapies work on the tumor cells to result in cell stasis or cell death. The same mechanism can result in toxicity to the normal gastrointestinal tract. Radiation therapy can cause acute and chronic injury. The chronic injury results from involvement of the vascular supply of the gastrointestinal tract and by causing fibrosis. The purpose of this article is to describe the imaging of complications resulting from oncologic treatment in the gastrointestinal system.

    Introduction. Laparoscopic radical nephroureterectomy (LNU) is being increasingly performed at several centers across the world. We review oncologic outcomes after LNU procedure and the techniques for the management of distal ureter. Materials and Methods. A comprehensive review of the literature was performed on the oncological outcomes and management of distal ureter associated with LNU for upper tract transitional cell carcinoma (TCC). Results and Discussion. LNU for upper tract TCC is performed pure laparoscopically (LNU) or hand-assisted (HALNU). The management of the distal ureter is still debated. LNU appears to have superior perioperative outcomes when compared to open surgery. Intermediate term oncologic outcomes after LNU are comparable to open nephroureterectomy (ONU). Conclusions. Excision of the distal ureter and bladder cuff during nephroureterectomy remains controversial. Intermediate term oncologic outcomes for LNU compare well with ONU. Initial long-term oncologic outcomes are encouraging. Prospective randomized comparison between LNU and open surgery is needed to define the role of these modalities in the current context.

    Minimally invasive surgery has been shown to offer many advantages to general surgical patients but has not been widely adopted for colorectal disease. Initial fears surrounding the oncological safety of laparoscopic colectomies have largely subsided but the technical challenges still remain. Surgical robots or telemanipulators present the laparoscopic surgeon with unrivaled dexterity and vision, which may allow colonic resections to be completed with greater ease. Although initial studies suggest promising results using currently available systems, it will take further time for patient benefits to be proven, therefore justifying the greater expense of operating with this new technology.

    Full Text Available Cancer is one of the leading causes of death throughout the world. Advancements in early and improved diagnosis could help prevent a significant number of these deaths. Raman spectroscopy is a vibrational spectroscopic technique which has received considerable attention recently with regards to applications in clinical oncology. Raman spectroscopy has the potential not only to improve diagnosis of cancer but also to advance the treatment of cancer. A number of studies have investigated Raman spectroscopy for its potential to improve diagnosis and treatment of a wide variety of cancers. In this paper the most recent advances in dispersive Raman spectroscopy, which have demonstrated promising leads to real world application for clinical oncology are reviewed. The application of Raman spectroscopy to breast, brain, skin, cervical, gastrointestinal, oral, and lung cancers is reviewed as well as a special focus on the data analysis techniques, which have been employed in the studies.

  14. Making cancer visible--Dyes in surgical oncology.

    Dyes share an intricate relationship with oncology. Dyes can cause cancer as chemical carcinogens, but can also be harnessed against cancer when used as diagnostic and therapeutic agents. Histopathology, imaging, and newer molecular diagnostics all rely on dyes, and their use in sentinel lymph node biopsies and intra-operative imaging has helped drive a paradigm shift in cancer surgery towards minimally-invasive and organ sparing approaches with enhanced resection accuracy. As therapeutic agents, the cytotoxicity of specific dyes can be employed in direct chemo-ablation or in photodynamic therapy. The same agent can have dual functionalities in cancer detection and treatment, in a novel field known as theranostics. This is facilitated by newer generation dyes conjugated with tumour-targeting probes such as antibodies, and these bio-conjugate agents can also incorporate nanotechnology or radio-isotopes. Further advances will be closely aligned with our increasing understanding of molecular oncology, and will form a new generation of cancer detection and treatment agents that promote precision medicine for cancer. Dyes and their roles have evolved and been reinvented, but they remain relevant as ever. This review explores the fascinating history of dyes, and their place in the state-of-the-art of oncology.

  15. Generalities of the oncological pain

    Full Text Available Cancer pain can be caused by a malignant tumor, by the therapy used to treat it, or by both causes. It begins with an acute onset that goes towards healing or chronicity. Together with the manifestations of a chronic pain, acute episodes may appear. A bibliographic study was carried out on the oncological pain, using the resources available in the Infomed network, specifically Ebsco, The Cochrane Librery, PubMed, Hinari and SciELO, by means of which the following databases were accessed: MEDLINE, AcademicSearch Premier and MedicLatina. The presence of pain in an oncological process is variable and it depends on the type and extension of the disease, as well as on each person's own individual tolerance. The terminal intense oncological pain is a circumstance both foreseeable and necessarily avoidable. Its relief is a priority in the cancer program of the World Health Organization. To know the classification of pain, its causes, the assessment scales and the way in which it may be described provides a comprehensive treatment for cancer pain. It also helps to optimize the comprehensive care to the patients suffering from this condition and improve their quality of life.

    The progress in oncological treatment has led to the current increase of childhood cancer survival rate to 80%. That is why orthodontists more and more frequently consult patients who had completed a successful anti-cancer therapy in childhood. Oncological treatments such as chemotherapy, radiotherapy or supportive immunosuppressive therapy cause numerous side effects in growing patients, connected i.a. with growth, the development of teeth or the viscerocranium. This is a special group of patients that needs an optimised plan of orthodontic treatment and often has to accept a compromise result. The purpose of the current work is to discuss the results of orthodontic treatment in patients after an anti-cancer therapy. Time of treatment was 12,5 months. In 6 patients (from 40 undergoing orthodontic therapy) we haven't reached a normocclusion, in 9 patients we should have stopped the therapy because of the recurrence. In 11 patients we found mucosa inflammation and in 1 patient the therapy stopped before the end because of very low oral hygiene level. Bearing in mind the limited number of original works on the above topic in Polish medical literature, the study has been carried out in order to make Polish orthodontists more acquainted with the topic and the standards of dealing with an oncological patient.

  17. Provider volume and outcomes for oncological procedures.

    LENUS (Irish Health Repository)

    Killeen, S D

    2012-02-03

    BACKGROUND: Oncological procedures may have better outcomes if performed by high-volume providers. METHODS: A review of the English language literature incorporating searches of the Medline, Embase and Cochrane collaboration databases was performed. Studies were included if they involved a patient cohort from 1984 onwards, were community or population based, and assessed health outcome as a dependent variable and volume as an independent variable. The studies were also scored quantifiably to assess generalizability with respect to any observed volume-outcome relationship and analysed according to organ system; numbers needed to treat were estimated where possible. RESULTS: Sixty-eight relevant studies were identified and a total of 41 were included, of which 13 were based on clinical data. All showed either an inverse relationship, of variable magnitude, between provider volume and mortality, or no volume-outcome effect. All but two clinical reports revealed a statistically significant positive relationship between volume and outcome; none demonstrated the opposite. CONCLUSION: High-volume providers have a significantly better outcome for complex cancer surgery, specifically for pancreatectomy, oesphagectomy, gastrectomy and rectal resection.

    2015-01-01

    Surgical robotic use has grown exponentially in spite of limited or uncertain benefits and large costs. In certain situations, adoption of robotic technology provides value to patients and society. In other cases, however, the robot provides little or no increase in surgical quality, with increased expense, and, therefore, does not add value to health care. The surgical robot is expensive to purchase, maintain and operate, and can contribute to increased consumerism in relation to surgical procedures, and increased reliance on the technology, thus driving future increases in health-care expenditure. Given the current need for budget constraints, the cost-effectiveness of specific procedures must be evaluated. The surgical robot should be used when cost-effective, but traditional open and laparoscopic techniques also need to be continually fostered.

    Colon cancer is the second leading cause of death for cancer disease, after lung cancer, with nearly 18,000 deaths per year in Italy. In spite of the progress that have taken place over the past 30 years, little improvement has been gained in this dismal outcome, and the 5-year survival remains around 50%. Over one half of the patients will suffer from recurrence after a potentially curative resection. A major challenge lies in better detection of recurrences in order to diagnose those patients still amenable to curative resection. Locoregional recurrence is of particular interest and its frequency, diagnostic limitations and surgical treatment are herein discussed.

    2009-09-01

    Full Text Available A robot functioning in an environment may exhibit various forms of behavior emerge from the interaction with its environment through sense, control and plan activities. Hence, this paper introduces a behaviour selection based navigation and obstacle avoidance algorithm with effective method for adapting robotic behavior according to the environment conditions and the navigated terrain. The developed algorithm enable the robot to select the suitable behavior in real-time to avoid obstacles based on sensory information through visual and ultrasonic sensors utilizing the robot's ability to step over obstacles, and move between surfaces of different heights. In addition, it allows the robot to react in appropriate manner to the changing conditions either by fine-tuning of behaviors or by selecting different set of behaviors to increase the efficiency of the robot over time. The presented approach has been demonstrated on quadruped robot in several different experimental environments and the paper provides an analysis of its performance.

    Cancer is a complex disease and unfortunately understanding how the components of the cancer system work does not help understand the behavior of the system as a whole. In the words of the Greek philosopher Aristotle "the whole is greater than the sum of parts." To date, thanks to improved information technology infrastructures, it is possible to store data from each single cancer patient, including clinical data, medical images, laboratory tests, and pathological and genomic information. Indeed, medical archive storage constitutes approximately one-third of total global storage demand and a large part of the data are in the form of medical images. The opportunity is now to draw insight on the whole to the benefit of each individual patient. In the oncologic patient, big data analysis is at the beginning but several useful applications can be envisaged including development of imaging biomarkers to predict disease outcome, assessing the risk of X-ray dose exposure or of renal damage following the administration of contrast agents, and tracking and optimizing patient workflow. The aim of this review is to present current evidence of how big data derived from medical images may impact on the diagnostic pathway of the oncologic patient.

  17. [Therapeutic Aggressiveness and Liquid Oncology].

    Barón Duarte, F J; Rodríguez Calvo, M S; Amor Pan, J R

    2017-01-01

    Aggressiveness criteria proposed in the scientific literature a decade ago provide a quality judgment and are a reference in the care of patients with advanced cancer, but their use is not generalized in the evaluation of Oncology Services. In this paper we analyze the therapeutic aggressiveness, according to standard criteria, in 1.001 patients with advanced cancer who died in our Institution between 2010 and 2013. The results seem to show that aggressiveness at the end of life is present more frequently than experts recommend. About 25% of patients fulfill at least one criterion of aggressiveness. This result could be explained by a liquid Oncology which does not prioritize the patient as a moral subject in the clinical appointment. Medical care is oriented to necessities and must be articulated in a model focused on dignity and communication. Its implementation through Advanced Care Planning, consideration of patient's values and preferences, and Limitation of therapeutic effort are ways to reduce aggressiveness and improve clinical practice at the end of life. We need to encourage synergic and proactive attitudes, adding the best of cancer research with the best clinical care for the benefit of human being, moral subject and main goal of Medicine.

    Cancer is a complex disease, characterized by alteration of different physiological molecular processes and cellular features. Keeping this in mind, the possibility of early identification and detection of specific tumor biomarkers by non-invasive approaches could improve early diagnosis and patient management.Different molecular imaging procedures provide powerful tools for detection and non-invasive characterization of oncological lesions. Clinical studies are mainly based on the use of computed tomography, nuclear-based imaging techniques and magnetic resonance imaging. Preclinical imaging in small animal models entails the use of dedicated instruments, and beyond the already cited imaging techniques, it includes also optical imaging studies. Optical imaging strategies are based on the use of luminescent or fluorescent reporter genes or injectable fluorescent or luminescent probes that provide the possibility to study tumor features even by means of fluorescence and luminescence imaging. Currently, most of these probes are used only in animal models, but the possibility of applying some of them also in the clinics is under evaluation.The importance of tumor imaging, the ease of use of optical imaging instruments, the commercial availability of a wide range of probes as well as the continuous description of newly developed probes, demonstrate the significance of these applications. The aim of this review is providing a complete description of the possible optical imaging procedures available for the non-invasive assessment of tumor features in oncological murine models. In particular, the characteristics of both commercially available and newly developed probes will be outlined and discussed.

    2016-05-01

    OBJECTIVE The authors' objective was to identify the 100 most-cited research articles in the field of spinal oncology. METHODS The Thomson Reuters Web of Science service was queried for the years 1864-2015 without language restrictions. Articles were sorted in descending order of the number of times they were cited by other studies, and all titles and abstracts were screened to identify the research areas of the top 100 articles. Levels of evidence were assigned on the basis of the North American Spine Society criteria. RESULTS The authors identified the 100 most-cited articles in spinal oncology, which collectively had been cited 20,771 times at the time of this writing. The oldest article on this top 100 list had been published in 1931, and the most recent in 2008; the most prolific decade was the 1990s, with 34 articles on this list having been published during that period. There were 4 studies with Level I evidence, 3 with Level II evidence, 9 with Level III evidence, 70 with Level IV evidence, and 2 with Level V evidence; levels of evidence were not assigned to 12 studies because they were not on therapeutic, prognostic, or diagnostic topics. Thirty-one unique journals contributed to the 100 articles, with the Journal of Neurosurgery contributing most of the articles (n = 25). The specialties covered included neurosurgery, orthopedic surgery, neurology, radiation oncology, and pathology. Sixty-seven articles reported clinical outcomes. The most common country of article origin was the United States (n = 62), followed by Canada (n = 8) and France (n = 7). The most common topics were spinal metastases (n = 35), intramedullary tumors (n = 18), chordoma (n = 17), intradural tumors (n = 7), vertebroplasty/kyphoplasty (n = 7), primary bone tumors (n = 6), and others (n = 10). One researcher had authored 6 studies on the top 100 list, and 7 authors had 3 studies each on this list. CONCLUSIONS This study identified the 100 most-cited research articles in the area of

  20. Robotics in gynecologic surgery.

    Science.gov (United States)

    Frick, A C; Falcone, T

    2009-06-01

    Robotic surgery has evolved from an investigational surgical approach to a clinically useful adjunct in multiple surgical specialties over the past decade. Advocates of robotic-assisted gynecologic surgery revere the system's wristed instrumentation, ergonomic positioning, and three-dimensional high-definition vision system as significant improvements over laparoscopic equipment's four degrees of freedom and two-dimensional laparoscope that demand the surgeon stand throughout a procedure. The cost, lack of haptic feedback, and the bulky size of the equipment make robotics less attractive to others. Studies evaluating outcomes in robotic-assisted gynecologic surgery are limited. Multiple small retrospective studies demonstrate the safety and feasibility of robotic hysterectomy. With increased surgeon experience, operative times are similar to, or shorter than, laparoscopic cases. Robotic assistance can facilitate suturing in laparoscopic myomectomies, and is associated with decreased blood loss and a shorter hospital stay, although may require longer operative times. Robotic assistance has also been applied to multiple procedures in the subspecialties of infertility, urogynecology and gynecologic oncology with good success and relatively low morbidity. However, further research is warranted to better evaluate the relative benefits and costs of robotic assisted gynecologic surgery.

  1. Robotic rectal surgery: what are the benefits?

    Science.gov (United States)

    Kim, C W; Baik, S H

    2013-10-01

    Robotic rectal surgery is not a rare event for colorectal surgeons any more. Even patients with colorectal diseases obtain information through the mass media and are asking surgeons about robotic surgery. Since laparoscopic rectal surgery has proved to have some benefits compared to open rectal surgery, many surgeons became interested in robotic rectal surgery. Some of them have reported the advantages and disadvantages of robotic rectal surgery over the last decade. This review will report on the outcomes of robotic rectal surgery. Robotic rectal surgery requires a longer operation time than laparoscopic or open surgery, but many authors reduced the gap as they were accustomed to the robotic system and used various additional techniques. The high cost for purchasing and maintaining the robotic system is still a problem, though. However, except for this reason, robotic rectal surgery shows comparable and even superior results in some parameters than laparoscopic or open surgery. They include pathologic and functional outcomes as well as short-term outcomes such as complication rates, length of hospital stay, time to recover normal bowel function or first flatus, time to start diet, and postoperative pain. Moreover, studies on oncologic outcomes show acceptable results. Robotic rectal surgery is safe and feasible and has a number of benefits. Therefore, it can be an alternative option to conventional laparoscopic and open surgery with strict indications.

  2. Implementation of nanoparticles in therapeutic radiation oncology

    Beeler, Erik; Gabani, Prashant; Singh, Om V.

    2017-05-01

    Development and progress of cancer is a very complex disease process to comprehend because of the multiple changes in cellular physiology, pathology, and pathophysiology resulting from the numerous genetic changes from which cancer originates. As a result, most common treatments are not directed at the molecular level but rather at the tissue level. While personalized care is becoming an increasingly aim, the most common cancer treatments are restricted to chemotherapy, radiation, and surgery, each of which has a high likelihood of resulting in rather severe adverse side effects. For example, currently used radiation therapy does not discriminate between normal and cancerous cells and greatly relies on the external targeting of the radiation beams to specific cells and organs. Because of this, there is an immediate need for the development of new and innovative technologies that help to differentiate tumor cells and micrometastases from normal cells and facilitate the complete destruction of those cells. Recent advancements in nanoscience and nanotechnology have paved a way for the development of nanoparticles (NPs) as multifunctional carriers to deliver therapeutic radioisotopes for tumor targeted radiation therapy, to monitor their delivery, and improve the therapeutic index of radiation and tumor response to the treatment. The application of NPs in radiation therapy has aimed to improve outcomes in radiation therapy by increasing therapeutic effect in tumors and reducing toxicity on normal tissues. Because NPs possess unique properties, such as preferential accumulation in tumors and minimal uptake in normal tissues, it makes them ideal for the delivery of radiotherapy. This review provides an overview of the recent development of NPs for carrying and delivering therapeutic radioisotopes for systemic radiation treatment for a variety of cancers in radiation oncology.

  3. Educating medical students about radiation oncology: initial results of the oncology education initiative.

    Multidisciplinary cancer care requires the integration of teaching across established educational boundaries. Because exposure to oncology and radiation oncology is limited in the undergraduate medical curriculum, the authors introduced an oncology education initiative at their institution. They report on the addition of structured multidisciplinary oncology education to the required radiology core clerkship. An institutional-based cohort study of fourth-year medical students rotating through a required clerkship in radiology at Boston University School of Medicine was conducted, beginning with the class of 2007. An educational questionnaire measuring the perceived quality of oncology education before and after exposure to a structured didactic program was administered. Of the 149 fourth-year students, 121 (81%) have completed the didactics of the initiative. Although 68 of 121 (56%) students reported having limited exposure to cancer care in the clinical years, 107 of 121 (88%) were motivated to learn more about the subject, and 100 of 121 (83%) reported a better understanding of the multidisciplinary nature of cancer care after this oncology education initiative. One hundred ten of 121 (91%) felt that the radiology clerkship was an opportune time to receive oncology and radiation oncology teaching. As a result of the initiative, 32% of the students pursued advanced training in radiation oncology. Of students who before the initiative were not planning on taking oncology electives, 70 of 99 (71%) agreed or strongly agreed that the lecture motivated them to learn more about the subject, and 43 of 99 (43%) agreed or strongly agreed that the lecture motivated them to take oncology electives. Systematic exposure to multidisciplinary oncology education as part of a radiology core clerkship provides an excellent opportunity for the integrated teaching of oncologic principles and patient management. This type of experience addresses an important yet underrepresented

    Musculoskeletal surgery is associated with a high risk of venous thrombosis and pulmonary embolism. The introduction of direct oral anticoagulants (DOAK) has broadened the possibilities for prevention of venous thromboembolism in the course of orthopedic and trauma surgery. Addressing this recent development, the Austrian Societies of Orthopedics and Orthopedic Surgery (ÖGO), Trauma Surgery (ÖGU), Hematology and Oncology (OeGHO) and of Anaesthesiology, Reanimation und Intensive Care Medicine (ÖGARI) have taken the initiative to create Austrian guidelines for the prevention of thromboembolism after total hip and knee replacement, hip fracture surgery, interventions at the spine and cases of minor orthopedic and traumatic surgery. Furthermore, the pharmacology of the DOAK and the pivotal trial data for each of the three currently available substances - apixaban, dabigatran, and rivaroxaban - are briefly presented. Separate chapters are dedicated to "anticoagulation and neuroaxial anesthesia" and "bridging".

By contrast, referral to a psychosocial specialist has typically been based on the patients expressed request for psychosocial support or the health care team's observation of the patient's limited adjustment or poor coping with the diagnosis, treatment, or end-of-life distress. These observations are usually based on clinical acumen not on metrics. In psychosocial oncology, by committing to the science of caring and relying on the use of standardized tools to screen for distress, the multidisciplinary cancer care team assess, communicate, and intervene on what is measured. That is, health care providers can begin to address the patients' identified concerns. Branding distress as the 6th vital sign and incorporating screening for distress into standard cancer practice can be an effective strategy to challenging the resistance in implementation of psychosocial oncology in cancer care institutions. Accreditation agencies are endorsing the need to assess patient distress and better manage symptoms of distress as part of routine and standardized patient care. While many international organizations and societies support the importance of screening, implementing screening for distress still has a long way to go to be operationalized in many cancer care programs. Screening for distress when implemented does, however, create an opportunity for psychosocial oncology to extend its reach into cancer care programs and institutions.

    Since 2003, genetics and genomics information has led to exciting new diagnostics, prognostics, and treatment options in oncology practice. Profiling of cancers offers providers insight into treatment and prognostic factors. Germline testing provides an individual with information for surveillance or therapy that may help them prevent cancer in their lifetime and options for family members as yet untouched by malignancy. This offers a challenge for oncology nurses and other oncology health care providers to become comfortable with incorporating education about genetics/genomics into their clinical practice and patient education.

    Fluorodeoxyglucose-PET is increasingly being integrated into multiple aspects of oncology. PET/computed tomography (PET/CT) has become especially important in radiation oncology. With the increasing use of advanced techniques like intensity-modulated radiation therapy and proton therapy, PET/CT scans have played critical roles in the target delineation of tumors for radiation oncologists delivering conformal treatment techniques. Use of PET/CT is well established in lung cancer and several other thoracic malignancies. This article details the current uses of PET/CT in thoracic radiation oncology with a focus on lung cancer and describes expected future roles of PET/CT for thoracic tumors.

    Objective Because the cancer population is aging, interprofessional education incorporating geriatric principles is essential to providing adequate training for oncology fellows. We report the targeted needs assessment, content, and evaluation tools for our geriatric oncology curriculum at MD Anderson Cancer Center. Methods A team comprising a geriatrician, a medical oncologist, an oncology PharmD, an oncology advanced nurse practitioner, and two oncology chief fellows developed the geriatric oncology curriculum. First, a general needs assessment was conducted by reviewing the literature and medical societies’ publications and by consulting experts. A targeted needs assessment was then conducted by reviewing the fellows’ evaluations of the geriatric oncology rotation and by interviewing fellows and recently graduated oncology faculty. Results Geriatric assessment, pharmacology, and psychosocial knowledge skills were the three identified areas of educational need. Curriculum objectives and an evaluation checklist were developed to evaluate learners in the three identified areas. The checklist content was validated by consulting experts in the field. Online materials, including a curriculum, a geriatric pharmacology job aid, and pharmacology cases, were also developed and delivered as part of the curriculum. Conclusion An interprofessional team approach was a successful method for identifying areas of learners’ educational needs, which in turn helped us develop an integrated geriatric oncology curriculum. The curriculum is currently being piloted and evaluated. PMID:25487037

    Full Text Available The National Cancer Institute clinical cooperative groups have been instrumental over the past 50 years in developing clinical trials and evidence based process improvements for clinical oncology patient care. The cooperative groups are undergoing a transformation process as we further integrate molecular biology into personalized patient care and move to incorporate international partners in clinical trials. To support this vision, data acquisition and data management informatics tools must become both nimble and robust to support transformational research at an enterprise level. Information, including imaging, pathology, molecular biology, radiation oncology, surgery, systemic therapy and patient outcome data needs to be integrated into the clinical trial charter using adaptive clinical trial mechanisms for design of the trial. This information needs to be made available to investigators using digital processes for real time data analysis. Future clinical trials will need to be designed and completed in a timely manner facilitated by nimble informatics processes for data management. This paper discusses both past experience and future vision for clinical trials as we move to develop data management and quality assurance processes to meet the needs of the modern trial.

    Full Text Available The aim of the present study was to quantify drug interactions in prescriptions for women undergoing supportive therapy in an oncology setting at a women’s hospital in Brazil and compare the information provided by different databases regarding these drug interactions. A convenience sample was selected of prescriptions for patients diagnosed with breast or gynecological tumors hospitalized in the clinical oncology and surgery wards from April to June 2009. DRUGDEX/Micromedex (Thomson Micromedex was the main database used for the identification of drug interactions and was compared with two other databases: Drugs.com and Lexicomp. The search was performed by inputting all drug combinations found in the prescriptions in Micromedex and Drugs.com. All interactions identified and classified by Micromedex and/or Drugs.com as of major severity were then checked in Lexicomp. A total of 152 interactions were identified by Micromedex (61 major, 69 moderate and 22 minor. In Drugs.com, 614 interactions were identified (85 major, 464 moderate and 65 minor. Forty-four were classified as major drug interactions in at least one of the databases: 30 in Micromedex, 26 in Drugs. com and 14 in Lexicomp. The present findings reveal discrepancies among the three databases analyzed. Thus, standardization should be proposed. Moreover, both the pharmacist and multidisciplinary team should perform a critical analysis of prescriptions to promote safe practices in the use of medications and minimize potential complications caused by drug interactions.

    Use of complementary and alternative medicine (CAM) has increased globally, particularly among oncology patients. This study investigated the knowledge, experience and attitudes of oncology nurses towards CAM. A quantitative study was conducted in tertiary care hospitals in Karachi, Pakistan, where 132 oncology nurses were surveyed. The survey revealed that more than 50% of nurses had never heard about many of the CAM therapies used in Pakistan. Approximately 65% of the nurses had knowledge about prayer and less than 30% had experience of CAM education or training. In addition, the majority of nurses had seen patients using CAM and felt that their health status could be enhanced with the use of CAM. This study showed that oncology nurses had a positive experience of and attitude towards CAM, although they needed to enhance their knowledge of it to maximise patient satisfaction and quality of care.

    Park, Seungwan; Kim, Nam Kyu

    2015-07-01

    The conventional laparoscopic approach to rectal surgery has several limitations, and therefore many colorectal surgeons have great expectations for the robotic surgical system as an alternative modality in overcoming challenges of laparoscopic surgery and thus enhancing oncologic and functional outcomes. This review explores the possibility of robotic surgery as an alternative approach in laparoscopic surgery for rectal cancer. The da Vinci® Surgical System was developed specifically to compensate for the technical limitations of laparoscopic instruments in rectal surgery. The robotic rectal surgery is associated with comparable or better oncologic and pathologic outcomes, as well as low morbidity and mortality. The robotic surgery is generally easier to learn than laparoscopic surgery, improving the probability of autonomic nerve preservation and genitourinary function recovery. Furthermore, in very complex procedures such as intersphincteric dissections and transabdominal transections of the levator muscle, the robotic approach is associated with increased performance and safety compared to laparoscopic surgery. The robotic surgery for rectal cancer is an advanced technique that may resolve the issues associated with laparoscopic surgery. However, high cost of robotic surgery must be addressed before it can become the new standard treatment.

    2013-01-01

    Resilience has been suggested as an important coping strategy for nurses working in demanding settings, such as paediatric oncology. This qualitative study explored paediatric oncology nurses' perceptions of their development of resilience and how this resilience underpinned their ability to deal with work-related stressors. Five paediatric oncology nurses were interviewed about their understanding of the concept of resilience, their preferred coping mechanisms, and their day-today work in paediatric oncology. Using thematic analysis, the interviews were subsequently grouped together into seventeen initial themes. These themes were then grouped into seven major aspects that described how the participants perceived resilience underpinned their work. These "seven aspects of forming resilience" contributed to an initial understanding of how paediatric oncology nurses develop resilience in the face of their personal and professional challenges. Several key strategies derived from the findings, such as improved rostering, support to a nurse's friend and family, and a clinical support nursing role, could be implemented at an organizational level to support resilience development within the paediatric oncology setting.

    Full Text Available Mathew C Raynor, Raj S PruthiDivision of Urologic Surgery, University of North Carolina at Chapel Hill, Chapel Hill, NC, USAAbstract: The past decade has seen a dramatic shift in the surgical management of certain urologic conditions with the advent of a robotic surgical platform. In fact, the surgical management of prostate cancer has seen the most dramatic shift, with the majority of cases now being performed robotically. Technical refinements over the years have led to improved outcomes regarding oncologic and functional results. Recently, robotic surgery has also been utilized for the surgical management of bladder cancer, renal cancer, and other benign conditions. As further experience is gained and longer-term outcomes are realized, robotic surgery will likely play an increasing role in the surgical management of many urologic conditions.Keywords: robot-assisted surgery, robotic surgery, cystectomy, prostatectomy, partial nephrectomy

    The use of clinical pathways in oncology care is increasingly important to patients and oncology providers as a tool for enhancing both quality and value. However, with increasing adoption of pathways into oncology practice, concerns have been raised by ASCO members and other stakeholders. These include the process being used for pathway development, the administrative burdens on oncology practices of reporting on pathway adherence, and understanding the true impact of pathway use on patient health outcomes. To address these concerns, ASCO's Board of Directors established a Task Force on Clinical Pathways, charged with articulating a set of recommendations to improve the development of oncology pathways and processes, allowing the demonstration of pathway concordance in a manner that promotes evidence-based, high-value care respecting input from patients, payers, and providers. These recommendations have been approved and adopted by ASCO's Board of Directors on August 12, 2015, and are presented herein.

  6. Hand-assisted laparoscopic surgery using Gelport

    2005-01-01

    Full Text Available Introduction: Minimally invasive surgery has revolutionized general surgery during the past 10 years. However, for more advanced surgical procedures, the acceptance of the minimally invasive approach has been slower than expected. Advanced laparoscopic surgery is complex and time-consuming. The major drawbacks of laparoscopic surgery are two-dimensional view, lack of depth perception and loss of tactile sensation. This has led to the innovation of hand-assisted laparoscopic surgery (HALS. The objective of the present study was to determine that safety of HALS. Materials and Methods: We preformed 18 HALS procedures in our department between July 2003 and January 2005 on patients who had given their informed consent for the use of Gelport. Out of these, 15 were colectomy, 2 nephrectomy and 1 splenectomy. Out of the 18 patients, 13 were males and 5 were females with the age group ranging from 44 to 72 years. Results: Hand-assisted laparoscopic surgery could be completed in 17 patients maintaining all the oncological principals of surgery. The mean operating times were 120 min for right haemicolectomy, 135 min for left colectomy, 150 min for splenectomy, and 150 min for nephrectomy. The patient undergoing radical nephrectomy by HALS had to be converted to open surgery. As the tumour was large and adherent to the spleen and posterior peritoneal wall. Postoperative recovery was excellent with an average hospital stay of 5 days. Histopathology report showed wide clearance and till date we have a good follow up of 30-380 days. Conclusion: Hand-assisted laparoscopic surgery allows tactile sensation and depth perception thereby may simplify the complex procedures. This may result in reduction of operating time and conversion rates at the same time maintaining all the oncological principles. Hand-assisted laparoscopic surgery strikes a perfect balance between an extended open laparotomy incision and an excessively tedious laparoscopic exercise. Hand

  7. Anesthetic Techniques and Cancer Recurrence after Surgery

    Directory of Open Access Journals (Sweden)

    Vincenzo Fodale

    2014-01-01

    Full Text Available Many of the most common anesthetics are used in surgical oncology, yet effects on cancer cells are still not known. Anesthesia technique could differentially affect cancer recurrence in oncologic patients undergoing surgery, due to immunosuppression, stimulation of angiogenesis, and dissemination of residual cancer cells. Data support the use of intravenous anesthetics, such as propofol anesthesia, thanks to antitumoral protective effects inhibiting cyclooxygenase 2 and prostaglandins E2 in cancer cells, and stimulation of immunity response; a restriction in the use of volatile anesthetics; restriction in the use of opioids as they suppress humoral and cellular immunity, and their chronic use favors angiogenesis and development of metastases; use of locoregional anesthesia compared with general anesthesia, as locoregional appears to reduce cancer recurrence after surgery. However, these findings must be interpreted cautiously as there is no evidence that simple changes in the practice of anesthesia can have a positive impact on postsurgical survival of cancer patients.

    2016-01-01

    Robotic surgery, used generally for colorectal cancer, has the advantages of a three-dimensional surgical view, steadiness, and seven degrees of robotic arms. However, there are disadvantages, such as a decreased sense of touch, extra time needed to dock the robotic cart, and high cost. Robotic surgery is performed using various techniques, with or without laparoscopic surgery. Because the results of this approach are reported to be similar to or less favorable than those of laparoscopic surgery, the learning curve for robotic colorectal surgery remains controversial. However, according to short- and long-term oncologic outcomes, robotic colorectal surgery is feasible and safe compared with conventional surgery. Advanced technologies in robotic surgery have resulted in favorable intraoperative and perioperative clinical outcomes as well as functional outcomes. As the technical advances in robotic surgery improve surgical performance as well as outcomes, it increasingly is being regarded as a treatment option for colorectal surgery. However, a multicenter, randomized clinical trial is needed to validate this approach.

    2016-02-01

    Imatinib, the first and arguably the best targeted therapy, became the springboard for developing drugs aimed at molecular targets deemed crucial to tumours. As this development unfolded, a revolution in the speed and cost of genetic sequencing occurred. The result--an armamentarium of drugs and an array of molecular targets--set the stage for precision oncology, a hypothesis that cancer treatment could be markedly improved if therapies were guided by a tumour's genomic alterations. Drawing lessons from the biological basis of cancer and recent empirical investigations, we take a more measured view of precision oncology's promise. Ultimately, the promise is not our concern, but the threshold at which we declare success. We review reports of precision oncology alongside those of precision diagnostics and novel radiotherapy approaches. Although confirmatory evidence is scarce, these interventions have been widely endorsed. We conclude that the current path will probably not be successful or, at a minimum, will have to undergo substantive adjustments before it can be successful. For the sake of patients with cancer, we hope one form of precision oncology will deliver on its promise. However, until confirmatory studies are completed, precision oncology remains unproven, and as such, a hypothesis in need of rigorous testing.

  10. Psycho-oncology: Searching for practical wisdom?

    Science.gov (United States)

    Butlin, Helen

    2015-10-01

    The debate is vigorous in psycho-oncology about whether spiritual, existential, and psychosocial are the most comprehensive terms for academic research discourses investigating meaning and purpose. A call-to-action email from the International Society of Psycho-Oncology included the term soul. The current essay highlights the historical and contemporary uses of "soul" to suggest that the re-emergent soul signifies a tacit quest for an "intangible" that seems missing in current constructs of clinical domains reflected in the vigor of the debates. It is suggested that the re-emergence of the pre-Medieval meaning(s) of the notion of soul affirms a growing need for integrative paradigms on "being human" to guide psycho-oncology practitioners and their research. As a paradigmatic example, a clinical support group entitled Soul Medicine is described as employing the term soul to open up the more marginal discourses about experiences of illness arising from philosophical reflection, arts, humanities, and spirituality within a clinical oncology context. A link between soul and wisdom is suggested for further exploration with the view that phronesis ("the virtue of practical wisdom"), an emerging concept in health professional education research, is of ultimate value to the people psycho-oncology seeks to serve. This group holds that garnering wisdom from the expertise of those living with cancer should be a central aim of our field.

    An analysis of economic and logistical problems of radiation oncology is presented based on domestic and foreign literature. Despite the high efficacy of radiotherapy this branch of oncology is not financed enough in most countries. As a consequence, it is ubiquitously marked radiotherapy capacity deficit that does not allow to fully realize its therapeutic potential. Medical electron accelerators and related equipment have become increasingly complex and expensive and radiotherapy techniques more consuming. Even in developed countries growing waiting times for radiotherapy, not using the most modern and efficient radiotherapy technologies (image guiding, etc.) has become a daily reality. Based on these data, we assessed the prospects and possibilities of upgrading the technical base of radiation oncology in Russia including the development of hadron therapy.

    To test the hypothesis that recent resident research productivity might be different than a decade ago, and to provide contemporary information about resident scholarly activity. We compiled a list of radiation oncology residents from the 2 most recent graduating classes (June 2014 and 2015) using the Association of Residents in Radiation Oncology annual directories. We queried the PubMed database for each resident's first-authored publications from postgraduate years (PGY) 2 through 5, plus a 3-month period after residency completion. We abstracted corresponding historical data for 2002 to 2007 from the benchmark publication by Morgan and colleagues (Int J Radiat Oncol Biol Phys 2009;74:1567-1572). We tested the null hypothesis that these 2 samples had the same distribution for number of publications using the Wilcoxon rank-sum test. We explored the association of demographic factors and publication number using multivariable zero-inflated Poisson regression. There were 334 residents publishing 659 eligible first-author publications during residency (range 0-17; interquartile range 0-3; mean 2.0; median 1). The contemporary and historical distributions were significantly different (Presearch (75%). In the historical cohort, half of all articles were published in 3 journals; in contrast, the top half of contemporary publications were spread over 10 journals-most commonly International Journal of Radiation Oncology • Biology • Physics (17%), Practical Radiation Oncology (7%), and Radiation Oncology (4%). Male gender, non-PhD status, and larger residency size were associated with higher number of publications in the multivariable analysis. We observed an increase in first-author publications during training compared with historical data from the mid-2000s. These contemporary figures may be useful to medical students considering radiation oncology, current residents, training programs, and prospective employers. Copyright © 2016 Elsevier Inc.

    endoscopic diagnosis is likely to be impacted by a combination of biomarkers and technology, and 'endoscopic molecular imaging' should be defined as "visualization of molecular characteristics with endoscopy". These innovations will allow us not only to locate a tumor or dysplastic lesion but also to visualize its molecular characteristics (e.g., DNA mutations and polymorphisms, gene and/or protein expression), and the activity of specific molecules and biological processes that affect tumor behavior and/or its response to therapy. In the near future, these methods should be promising technologies that will play a central role in gastrointestinal oncology.

    The objective of the study was to analyze a group of patients with low grade parosteal osteosarcoma treated with limb salvage surgery and reconstructed with bone allograft. A retrospective review from our oncologic data base between 1980 and 2010 was done and all patients with diagnosis of low grade parosteal osteosarcoma, treated with limb salvage surgery and reconstructed with allograft were included. Twenty-two patients were included for the analysis. The mean age was 32±11 years (10-59) y the mean follow-up 93±69 months (8-237). Ten year overall survival of the series was 91% (95% CI: 79-100). Four patients developed local recurrence, 2 of them histological classified after the resection dedifferentiated parosteal osteosarcoma. Two patients developed distant recurrence, being the lung the only site of metastasis. Ten year limb salvage reconstruction survival was 65% (95% CI: 44-86). Long term survival rate in low grade parosteal osteosarcoma is over 90%. Surgical resection wide margin should be the elective treatment and biological limb salvage reconstruction is a good alternative.

    The articles on thoracic oncology published in this journal during the year 2008 are briefly commented on. As regards the epidemiology, it is noted that the standardised incidence rate of lung cancer in males is starting to decline, and there is another study that analysed links between two common diseases, COPD and lung cancer. Other works have focused on aspects such as diagnosis, staging or prognosis, and analysing the value of positron emission tomography in the assessment of a solitary pulmonary nodule, the effectiveness of aspiration transbronchial needle aspiration in mediastinal staging, the prognostic significance of the over-expression and amplification of c-erbB-2 in patients with small cell carcinoma. As regards treatment, other authors analysed the survival of patients with N2 lung cancer detected during or after lung resection surgery. The new therapeutic technique of ablation of lung tumours by radiofrequency in the early stages is the subject of two publications that describe its basis, indications, contraindications and first results. Lastly, the communication skills needed to inform patients, surgery of lung metastases, and the presentation of an unusual case of carcinoid tumour were the subjects of other articles.

    Based on necropsy review, neoplasia in reptiles has a comparable frequency to that of mammals and birds. Reptile neoplasia is now more frequently diagnosed in clinical practice based on increased use of advanced diagnostic techniques and improvements in reptilian husbandry allowing greater longevity of these species. This article reviews the current literature on neoplasia in reptiles, and focuses on advanced diagnostics and therapeutic options for reptilian patientssuffering neoplastic disease. Although most applied clinical reptile oncology is translated from dog and cat oncology, considerations specific to reptilian patients commonly encountered in clinical practice (turtles, tortoises, snakes, and lizards) are presented.

    The scientific literature contains a wealth of information concerning spontaneous fish neoplasms, although ornamental fish oncology is still in its infancy. The occurrence of fish neoplasms has often been associated with oncogenic viruses and environmental insults, making them useful markers for environmental contaminants. The use of fish, including zebrafish, as models of human carcinogenesis has been developed and knowledge gained from these models may also be applied to ornamental fish, although more studies are required. This review summarizes information available about fish oncology pertaining to veterinary clinicians.

    2013-01-01

    In just over a decade, robotic surgery has penetrated almost every surgical subspecialty and has even replaced some of the most commonly performed open oncologic procedures. The initial reports on patient outcomes yielded mixed results, but as more medical centers develop high-volume robotics programs, outcomes appear comparable if not improved for some applications. There are limitations to the current commercially available system, and new robotic platforms, some designed to compete in the current market and some to address niche surgical considerations, are being developed that will change the robotic landscape in the next decade. Adoption of these new systems will be dependent on overcoming barriers to true telesurgery that range from legal to logistical. As additional surgical disciplines embrace robotics and open surgery continues to be replaced by robotic approaches, it will be imperative that adequate education and training keep pace with technology. Methods to enhance surgical performance in robotics through the use of simulation and telementoring promise to accelerate learning curves and perhaps even improve surgical readiness through brief virtual-reality warm-ups and presurgical rehearsal. All these advances will need to be carefully and rigorously validated through not only patient outcomes, but also cost efficiency.

    Full Text Available In her experiential world, the oncology nurse experiences unique, challenging and rewarding relationships in a multidimensional, dynamic way. The aim of this study was to describe, from her viewpoint and perspective, how she experiences and reacts to this world. Through this study the researcher wants the oncology nurse’s voice to be heard, the richness of her story acknowledged and the derived data to be applied to the benefit of the field of oncology. In-depth, unstructured phenomenological interviews provided the saturated data from which the uniqueness of the world of the oncology nurse unfolded as the uniqueness of the oncology patients and their world emerged clearly. Findings show that the oncology nurse, attending to the cancer patients and their family, experiences many different relationships. The uniqueness of the oncology nurse-patient relationship is described as unlike any other nurse-patient relationship. The challenging interpersonal relationships with management and other members of the multiprofessional team, as experienced from the perspective of the oncology nurse, are also highlighted. Furthermore, a unifying intrapersonal relationship with the self was identified. This enables the oncology nurse to be both on the giving and receiving end of the intensely emotional environment she works in, explaining, at least partly, the high job satisfaction that permeated the interviews in this study. Recommendations for nursing practice, education and research were formulated.

    Full Text Available Objectives: A survey was conducted among freshly passed undergraduate doctors of a medical college in Eastern India with the aim to investigate their exposure to oncology patients, their knowledge about various aspects of oncology patient management and their confidence in managing patients with cancer. Materials and Methods: One hundred and twelve newly passed interns of a Government Medical College in Kolkata were interviewed using semi-structured partly open ended and partly closed end questionnaire. The questionnaire dealt with the qualitative and quantitative aspects of knowledge and perception of the interns about the problem of cancer and its management. Results: A total of 82 interns responded to the questionnaire, with a response rate of 73.2%. About 53% of the respondents have seen less than five patients during their undergraduate ward/clinical postings. Among the respondents, 71% felt they were confident in diagnosing cancer, and about 56% were confident in counseling of patient and their relatives about cancer. About 63% were aware about the role of surgery; however, only 32% and 37.5% were aware about the role of radiotherapy and chemotherapy, respectively. A dismal 12.5% were confident of care of terminal and late stage patients. Preparedness was correlated with exposure to patients with cancer ( P = 0.03. Majority (87% felt the need for incorporating oncology training at the undergraduate level and the most frequent method (67% suggested for doing so was having separate posting in radiotherapy department/oncology wards. Conclusion: There is glaring knowledge gap among newly passed doctors and integrated oncology postings during undergraduate training and during internship may help seal this gap.

  12. Intraoperative OCT in Surgical Oncology

    Science.gov (United States)

    South, Fredrick A.; Marjanovic, Marina; Boppart, Stephen A.

    The global incidence of cancer is rising, putting an increasingly heavy burden upon health care. The need to effectively detect and treat cancer is one of the most significant problems faced in health care today. Effective cancer treatment typically depends upon early detection and, for most solid tumors, successful removal of the cancerous tumor tissue via surgical procedures. Difficulties arise when attempting to differentiate between normal and tumor tissue during surgery. Unaided visual examination of the tissue provides only superficial, low-resolution information and often with little visual contrast. Many imaging modalities widely used for cancer screening and diagnostics are of limited use in the operating room due to low spatial resolution. OCT provides cellular resolution allowing for more precise localization of the tumor tissue. It is also relatively inexpensive and highly portable, making it well suited for intraoperative applications.

    The Oncology Education Initiative was established in 2007 in an effort to advance oncology and radiation oncology education at the undergraduate level. As a continuation of the initiative, the aim of this study was to determine whether these structured didactics would continue to increase overall medical student knowledge about oncologic topics. Preclerkship and postclerkship tests examining concepts in general oncology, radiation oncology, breast cancer, and prostate cancer were administered. The 21-question, multiple-choice examination was administered at the beginning and end of the radiology clerkship, during which a 1.5-hour didactic session was given by an attending radiation oncologist. Changes in individual question responses, student responses, and overall categorical responses were analyzed. All hypothesis tests were two tailed with a significance level of .05. In the 2009-2010 academic year, 155 third-year and fourth-year students had average examination score improvements from 62% to 68.9% (P students and decreased among fourth-year students. In the successive years since its inception, the Oncology Education Initiative continues to show a significant improvement in medical students' knowledge of cancer. The initiative has also succeeded in providing radiation oncology education to all graduating medical students at the authors' institution. Dedicated oncology education in the undergraduate medical curriculum provides students with a better understanding of multidisciplinary oncology management.

    2012-01-01

    Full Text Available In spite of the recent improvements in drug therapy, surgery still represents the most frequent treatment for Crohn's disease (CD complications. Laparoscopy has been widely applied over the last twenty years in colorectal surgery and was associated with lower postoperative pain, shorter hospitalization, faster return to daily activities, and better cosmetic results. Laparoscopy experienced a slower diffusion in inflammatory bowel disease surgery than in oncologic colorectal surgery, but proved to be safe and effective, and is currently considered the gold standard for the treatment of primary uncomplicated ileocolic CD. Indications for laparoscopy in CD have recently been widened to embrace more complicated or recurrent CD. This paper reviews the available data on the subset of recurrent CD patients. The reported results indicate that laparoscopy may be safely applied even in selected recurrent CD cases in hands of IBD surgeons with broad laparoscopic experience.

    Gonca Elçin

    2015-12-01

    Full Text Available A considerable number of dermatolologist in Turkey perform standard surgical excision of non-melanoma skin cancer and repair the defects functionally and cosmetically. It is possible to appropriately treat most basal cell carcinomas (BCCs and squamous cell carcinomas (SCCs with standard excision and even with curettage and electrodessication. However, for a group of patients at high risk of recurrence, standard excision cannot provide the desired oncologic cure rates. In order to increase the possibility of oncologic cure, it is recommended that high risk BCCs and SCCs should be excised with larger than 4-6 mm safety margins. On the other hand the most common localization for BCCs and SCCs are the face, and using safety margins larger than 4-6 mm on the face might contradict with the principles of tissue-preserving surgical approach. A more unfavorable situation is that the oncologic cure rates remain below 80% for high-risk BCC and SCC even after standard excisions with safety margins of wider than 4-6 mm. The goal of Mohs micrographic surgery is complete tumor removal with maximum preservation of healthy tissue.. Mohs micrographic surgery is a staged surgery that enables 100% assessment of the entire lateral and deep surgical margins microscopically in minutes after excision with horizontally cut frozen sections for residual cancer. Thus, it increases the oncologic cure rate especially for a certain group of patients with high-risk BCC and SCC. The aim of this paper was to review the Mohs technique, the most thorough method for treating BCC and SCC.

    2004-10-01

    Laser surgery represents the evolution of endoscopic surgery and, as far as concerns treatment of laryngeal tumours, CO2 laser cordectomy is considered a valid alternative to conventional surgery (laryngofissure cordectomy) and to exclusive radiotherapy for glottic carcinomas, classified as T1a, T1b and T2. The present report focuses on personal experience with CO2 laser cordectomy over the last 11 years, evaluating oncological and functional results. Between October 1990 and December 2001, micro-laryngoscopy has been performed with CO, laser, in 606 cases (benign and malignant lesions), of which 150 laser cordectomies, at the ORL Department, Eastern Piedmont University of Novara. An analysis is made of 63 patients (mean age 64.3 years) who underwent laser cordectomy for glottic carcinoma, observed at follow-up for at least 3 years. Vocal function has been studied on a sample of 20 patients. Of those who underwent CO2 laser cordectomy for T1a and T1s, 95.8% were disease free after a minimum of 3 years follow-up. Video-larynx-stroboscopic test highlighted the presence of a "satisfying" fibrous neocord in cases treated with Type III cordectomy. The speech compensation was of the "cord-neocordal" type (35%), false cordal (40%) and with arytenoideus hyperadduction (25%). The electro-acoustical analysis of the voice highlighted a "serious dysphonia" compatible with Type IV cases according to Yanagihara (70%) and moderate-severe dysphonia (30%). Mean values of vocal parameters were 5.8% for Jitter, 12.2% for Shimmer, 0.34 for NHR. CO2 laser cordectomy is first choice treatment for T1a glottic carcinoma, offering intra- and post-operative advantages: reduced traumatism, lack of tracheostomy, low bleeding, fast functional recovery (deglutition and speech), brief hospital stay, and low management costs. Dysphonia resulting from treatment, characterised by breathed voice, allows the patient to lead a normal life.

    Radiation therapy is an effective, personalized cancer treatment that has benefited from technological advances associated with the growing ability to identify and target tumors with accuracy and precision. Given that these advances have played a central role in the success of radiation therapy as a major component of comprehensive cancer care, the American Society for Radiation Oncology (ASTRO), the American Association of Physicists in Medicine (AAPM), and the National Cancer Institute (NCI) sponsored a workshop entitled "Technology for Innovation in Radiation Oncology," which took place at the National Institutes of Health (NIH) in Bethesda, Maryland, on June 13 and 14, 2013. The purpose of this workshop was to discuss emerging technology for the field and to recognize areas for greater research investment. Expert clinicians and scientists discussed innovative technology in radiation oncology, in particular as to how these technologies are being developed and translated to clinical practice in the face of current and future challenges and opportunities. Technologies encompassed topics in functional imaging, treatment devices, nanotechnology, and information technology. The technical, quality, and safety performance of these technologies were also considered. A major theme of the workshop was the growing importance of innovation in the domain of process automation and oncology informatics. The technologically advanced nature of radiation therapy treatments predisposes radiation oncology research teams to take on informatics research initiatives. In addition, the discussion on technology development was balanced with a parallel conversation regarding the need for evidence of efficacy and effectiveness. The linkage between the need for evidence and the efforts in informatics research was clearly identified as synergistic.

  7. Excisional surgery for cancer cure: therapy at a cost.

    LENUS (Irish Health Repository)

    Coffey, J C

    2012-02-03

    Excisional surgery is one of the primary treatment modalities for cancer. Minimal residual disease (MRD) is the occult neoplastic disease that remains in situ after curative surgery. There is increasing evidence that tumour removal alters the growth of MRD, leading to perioperative tumour growth. Because neoplasia is a systemic disease, this phenomenon may be relevant to all patients undergoing surgery for cancer. In this review we discuss the published work that addresses the effects of tumour removal on subsequent tumour growth and the mechanisms by which tumour excision may alter residual tumour growth. In addition, we describe therapeutic approaches that may protect patients against any oncologically adverse effects of tumour removal. On the basis of the evidence presented, we propose a novel therapeutic paradigm; that the postoperative period represents a window of opportunity during which the patient may be further protected against the oncological effects of tumour removal.

    Purpose: The aim of this study was to report on the development of a standardized target and organ-at-risk naming convention for use in radiation therapy and to present the nomenclature for structure naming for interinstitutional data sharing, clinical trial repositories, integrated multi-institutional collaborative databases, and quality control centers. This taxonomy should also enable improved plan benchmarking between clinical institutions and vendors and facilitation of automated treatment plan quality control. Materials and Methods: The Advanced Technology Consortium, Washington University in St. Louis, Radiation Therapy Oncology Group, Dutch Radiation Oncology Society, and the Clinical Trials RT QA Harmonization Group collaborated in creating this new naming convention. The International Commission on Radiation Units and Measurements guidelines have been used to create standardized nomenclature for target volumes (clinical target volume, internal target volume, planning target volume, etc.), organs at risk, and planning organ-at-risk volumes in radiation therapy. The nomenclature also includes rules for specifying laterality and margins for various structures. The naming rules distinguish tumor and nodal planning target volumes, with correspondence to their respective tumor/nodal clinical target volumes. It also provides rules for basic structure naming, as well as an option for more detailed names. Names of nonstandard structures used mainly for plan optimization or evaluation (rings, islands of dose avoidance, islands where additional dose is needed [dose painting]) are identified separately. Results: In addition to its use in 16 ongoing Radiation Therapy Oncology Group advanced technology clinical trial protocols and several new European Organization for Research and Treatment of Cancer protocols, a pilot version of this naming convention has been evaluated using patient data sets with varying treatment sites. All structures in these data sets were

    On October 31, 2015, the first Sino-Dutch symposium on oncology was organized in Guangzhou (China). The sym-posium revealed similarities between Chinese and Dutch efforts to improve the care of tumor patients and to create enhanced insight into the nature of cancers. In particular, it became evident for some types of cancer that immuno-therapy should focus on counteracting interleukin-17-associated immunity and targeting cancer stroma. Targeting specific cancer microenvironment and stroma also opens new therapeutic options, including the use of radio-active theranostics and live tumor imaging-guided surgeries.

    ABSTRACT: BACKGROUND: The objective was to understand patients' views of treatment after acute anterior cruciate ligament (ACL) injury, and their reasons for deciding to request surgery despite consenting to participate in a randomised controlled trial (to 'cross-over'). METHODS: Thirty-four in......-depth qualitative interviews were conducted with young (aged 18-35), physically active individuals with ACL rupture who were participating in a RCT comparing training and surgical reconstruction with training only. 22/34 were randomised to training only but crossed over to surgery. Of these, 11 were interviewed...... before surgery, and 11 were interviewed at least 6 months after surgery. To provide additional information, 12 patients were interviewed before randomisation. Interviews were audio-recorded, transcribed and analysed using the Framework approach. RESULTS: Strong preference for surgery was commonplace...

    Delaying initiation of adjuvant chemotherapy more than 8 weeks after surgical resection for colorectal cancer adversely affects overall patient survival. The effect of a laparoscopic surgical approach on initiation of chemotherapy has not been studied. The goal of this study was to determine if a laparoscopic approach to colon cancer resection affects the timing of adjuvant chemotherapy and outcomes. Patients who underwent curative surgery for stage II or III colon cancer and received adjuvant chemotherapy between 2003 and 2010 were identified from a prospectively maintained database. Patients were categorized according to surgical approach: open or laparoscopic. Patient demographics, clinicopathologic variables, postoperative complications, time from surgery to initiation of chemotherapy, and long-term oncologic outcomes were compared. Age, gender, ASA class, BMI, tumor stage, and postoperative complications were similar for laparoscopic and open cases, while length of stay was 2 days shorter for laparoscopic cases (5.4 vs 7.6 days, p < 0.01). The proportion of patients who received adjuvant chemotherapy more than 8 weeks after surgery did not differ between the groups (35.6 % open vs 38.7 % laparoscopic, p = 0.77). In the open group, delay in chemotherapy after surgery was associated with decreased disease-free and overall survival (p = 0.01, 0.01, respectively). However, delay in chemotherapy more than 8 weeks did not affect disease-free or overall survival in the laparoscopy group (p = 0.93, 0.51, respectively). The benefits of quicker recovery after laparoscopic surgery did not translate into earlier initiation of adjuvant chemotherapy in this retrospective study. However, a laparoscopic approach negated the inferior oncologic outcomes of patients who received delayed initiation of chemotherapy.

The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery.Results: Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001, but the time to soft food intake (6.0 vs 6.6 days, P=0.036 and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018 were shorter in the laparoscopic group.

    Elkins, Gary; Fisher, William; Johnson, Aimee

    2010-12-01

    There is growing interest in mind-body therapies as adjuncts to mainstream cancer treatment, and an increasing number of patients turn to these interventions for the control of emotional stress associated with cancer. Increased research funding has enabled many such interventions to be evaluated for their efficacy, including studies of mind-body interventions to reduce pain, anxiety, insomnia, anticipatory, and treatment-related nauseas, hot flashes, and improved mood. Mind-body treatments evaluated for their utility in oncology include relaxation therapies, biofeedback, meditation and hypnosis, yoga, art and music therapy, tai chi, and qigong. Although studies are not always methodologically sound and results mixed, a growing number of well-designed studies provide convincing evidence that mind-body techniques are beneficial adjuncts to cancer treatment. The evidence is sufficient to recommend further investigation and adoption of these techniques in mainstream oncology care.

    Goitein, Michael

    2007-01-01

    Radiation Oncology: A Physicist's-Eye View was written for both physicists and medical oncologists with the aim of helping them approach the use of radiation in the treatment of cancer with understanding, confidence, and imagination. The book will let practitioners in one field understand the problems of, and find solutions for, practitioners in the other. It will help them to know "why" certain approaches are fruitful while, at the same time, encouraging them to ask the question "Why not?" in the face of assertions that some proposal of theirs is impractical, unreasonable, or impossible. Unlike a textbook, formal and complete developments of the topics are not among the goals. Instead, the reader will develop a foundation for understanding what the author has found to be matters of importance in radiation oncology during over thirty years of experience. Presentations cover, in largely non-technical language, the principal physical and biological aspects of radiation treatment and address practical clinical c...

    2014-09-10

    In the current health care system, high costs without proportional improvements in quality or outcome have prompted widespread calls for change in how we deliver and pay for care. Value-based health care delivery models have been proposed. Multiple impediments exist to achieving value, including misaligned patient and provider incentives, information asymmetries, convoluted and opaque cost structures, and cultural attitudes toward cancer treatment. Radiation oncology as a specialty has recently become a focus of the value discussion. Escalating costs secondary to rapidly evolving technologies, safety breaches, and variable, nonstandardized structures and processes of delivering care have garnered attention. In response, we present a framework for the value discussion in radiation oncology and identify approaches for attaining value, including economic and structural models, process improvements, outcome measurement, and cost assessment.

    Full Text Available Resilience like ability to overcome adversity and even learn and get out “strengthened” them has become, in the last decade, the focus of many studies throughout the life cycle and in different cultures. On the other hand, oncological disease was introduced globally in a high percentage of the population requiring labor and health team including psychologists for coping on the part of the patient and their family members. The authors cited in the course of this article refer to the importance of developing resilience at the personal, family and cultural level, started with the presence of trust relationships, cultivating positive emotions, the acceptance of different cycles of life and belief in a just world. These promoting resilience factors are the springs that allow the experience of oncological disease and even death and mourning as opportunities to generate personal and familiar learning.

    Evrard, Serge

    2016-01-01

    The evidence base for the effectiveness of surgical interventions is relatively poor and data from large, randomized prospective studies are rare with often a poor quality. Many efforts have been made to increase the number of high quality randomized trials in surgery and theoretical proposals have been put forward to improve the situation, but practical implementation of these proposals is seriously lacking. The consequences of this policy are not trivial; with very few patients included in surgical oncology trials, this represents wasted opportunity for advances in cancer treatment. In this review, we cover the difficulties inherent to clinical research in surgical oncology, such as quality control, equipoise, accrual, and funding and promote alternative designs to the randomized controlled trial. Although the classic randomized controlled trial has a valid but limited place in surgical oncology, other prospective designs need to be promoted as a new deal. This new deal not only implicates surgeons but also journal editors, tender jury, as well as regulatory bodies to cover legal gaps currently surrounding surgical innovation.

    Background Robotic-assisted surgery has potential benefits over laparoscopy yet little has been published on the integration of this platform into complex surgical oncology. We describe the outcomes associated with integration of robotics into a large surgical oncology program, focusing on metrics of safety and efficiency. Methods A retrospective review of a prospectively maintained database of robotic procedures from July 2009 to October 2014 identifying trends in volume, operative time, complications, conversion to open, and 90-day mortality. Results Fourteen surgeons performed 1236 cases during the study period: thyroid (246), pancreas/duodenum (458), liver (157), stomach (56), colorectal (129), adrenal (38), cholecystectomy (102), and other (48). There were 38 conversions to open (3.1%), 230 complications (18.6%), and 13 mortalities (1.1%). From 2009 to 2014, operative volume increased (7 cases/month vs 24 cases/month; P robotic surgical oncology program utilizing multiple surgeons is safe and feasible. As operative volume increased, operative time, complications, and conversions to open decreased and plateaued at approximately 3 years. No unanticipated adverse events attributable to the introduction of this platform were observed.

    The continual and increasing complexity of diagnostic and treatment options in oncology demands careful communication, coordination and decision making. Cancer care could be improved by multidisciplinary teamwork. Although this sort of teamwork has many advantages in theory, we know very little about its effectiveness in practice. We have to answer questions such as how teams can accomplish their task most effectively and how we must manage organizations in such a way that team-based working contributes optimally to organizational effectiveness.

    2007-01-01

    Oncologists and related health care professionals (HCPs) do not only have to follow professional protocols in their everyday work, but also have to communicate proper attitudes towards patients suffering from malignant diseases. This task is often a heavier load than the implementation of professional activities themselves. The present article is based on a survey on HCP work motivation, employment parameters and correlations with emotional labour. Fifty oncology HCPs at Debrecen University Medical Health Sciences Centre volunteered to participate in this survey containing 20 simple-choice questions. More than 90 percent of HCPs make an effort to hide their emotional state, giving way to possible negative side effects. The survey showed significant differences between the level of emotional labour of those working in the field of oncology longer or shorter than ten years. Surface and deep emotional labour is more frequent among professionals already working in oncology for a longer period of time. This can serve us with explanation to the burn-out syndrome so frequent in this profession. To diminish the load of emotional labour, healthcare institutes have to aim at hiring employees that spontaneously fit the emotional and behavioural norms facing them, and do not need officially prescribed behavioural norms for everyday work. Their constant need for respect and appreciation of their values must be kept in mind, because the capability of genuine emotional labour diminishes parallel to the number of years spent in work.

    With the ready availability of powerful desktop computers, the ability to manage large clinical databases has become practical. A computer can enhance the capability of a gynecologic oncology service to catalog, recall, and analyze data about patients, tumors, and therapies. While commercially available database packages can be used for this purpose, we have developed a custom database for tracking the clinical activity of a busy gynecologic oncology service. The system catalogs data about patients, admissions, tumors, and therapeutic modalities and uses this information to generate several useful reports. The reports are used for daily patient care, fellow and resident case statistics, and clinical research. What is unique about the system is that it is optimized for ease of use. The development of this tumor registry, its user friendliness, and advantages over a manual recordkeeping system are described. Unlike other tumor registries, our system is utilized on a daily basis for patient care. Therefore, the data being entered have an immediate usefulness in addition to being simultaneously added to the tumor register for retrospective clinical research. One may hypothesize that it would be useful if all gynecologic oncology services used a common computerized tumor registry that could allow for the sharing of information on a national or global scale.

    2014-06-01

    This article attempts to answer the following normative questions: Can one consider the design of Phase 1 trials ethically appropriate due to the unfavorable ratio of risks and benefits? What are some ethical safeguards for Phase 1 oncology research? A comparative review of literature contributed to the consolidation of the proposed ethical framework for Phase 1 oncology trials. This framework gives a special attention to issues of therapeutic misconception and vulnerability. The benefits and dangers associated with the enrollment in trials are described as well as the absence of alternatives, treatment-specific optimism, and vagueness in factual presentation during the informed consent process. The notion of therapeutic misconception is contrasted with optimism despite realism that stems from psychological, cultural, and religious factors and not necessarily from the lack of information. Close attention is given to the possible ways in which the inherent uncertainty and resulting cognitive biases may affect the informed consent process and the definition of therapeutic misconception. The article ends with recommendations for an ethical way of enrolling palliative patients in early stages of oncology research, giving special attention to provision of adequate consent, protection of vulnerability, and avoidance of therapeutic misconception.

    Over the past decade, robotic surgery has gained wide popularity, making a significant impact on multiple surgical specialties. In the head and neck arena, transoral robotic surgery has proven to be safe and associated with acceptable oncological and superior functional outcomes for surgery of the oropharynx, hypopharynx, supraglottis, and glottis; thus, changing the paradigm for the management of tumors in these anatomic locations. Robotic surgery of the ventral skull base is at an early stage of development. In this article reviews the literature discussing the role of robotic surgery in managing sinonasal and ventral skull base malignant lesions.

  11. Rational application of tumor marker CA 125 in gynecological oncology

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Introduction CA 125 determination started in 1981, when Bast et al. discovered monoclonal antibody OC-125 belonging to immunoglobulin G class (IgG1 using Köhler and Milstein's technique of hybridization. CA 125 antigen is produced in amniotic cells of the 7 week-old embryo, while in adults it can be detected in epithelium of most organs which originate from Müller ducts. The upper level of referent values for CA 125 in serum is 35 U/mL and can be seen in about 99% of healthy people. Application of tumor marker CA 125 in gynecological oncology More than 83% of patients with epithelial ovarian carcinoma have elevated values of CA 125 higher than 35 U/mL at the moment of diagnosing the disease. In cases of ovarian carcinoma, preoperatively determined values of CA 125 in serum are correlated with the extent of the expansion of the disease , histological type of tumor and degree of differentiation of malignant cells. Elevated values up to 65 U/mL in serum can also be found in other malignant tumors (pancreas, breast, colon, bladder, lungs, liver and in different benign diseases. The level of serum CA 125 after the surgery can indicate regression or progression of ovarian carcinoma in more than 90% of the patients who had had elevated values of CA125 prior to the surgery. Postoperative levels of CA 125 >35 U/mL in patients with no residual tumor and values >65 U/mL in those with residual tumor implants represent a separate prognostic factor in further course of the disease. Conclusion The importance of continuous determination of CA 125 tumor marker has to be adjusted to each single case.

    Curative treatment of head and neck squamous cell carcinoma includes surgery and/or (chemo)radiation, whereas in the palliative setting, chemotherapy and/or immunotherapy represent(s) the standard approach. With regard to quality control, methods for determining treatment response are sorely needed. For surgical therapy, histopathology is the standard quality control. Established criteria for high-risk patients include resection margins of the primary tumor and extracapsular extension of lymph node metastases. After definitive chemoradiation, treatment response is generally evaluated by tomographic imaging combined with endoscopy including re-biopsy of the tumor region. Single-cycle induction chemotherapy may be used to determine the radiosensitivity of tumors, helping to define surgical and nonsurgical treatment options. Innovative approaches with implications for prognosis include the analysis of immune infiltrates, liquid biopsy, molecular characterization (proteomics, genomics), molecular and functional imaging (PET-CT, PET-MRI), as well as advanced imaging data analysis (radio[geno]mics/texture analysis). Human papilloma virus, as a prognostically relevant parameter, is currently being investigated for de-escalation strategies. With regard to the extended personalization of oncologic therapy, markers predicting treatment response are desirable and seem to be important, also from a socioeconomic perspective. © 2017 S.

    Number and type of complications after ovarian cancer surgery can vary greatly according to both the patient's characteristics, and the extension and type of surgery. Current literature lacks in mentioning specific gastrointestinal side effects, which could be evidenced during the early postoperative course of patients submitted to major gynecological oncologic surgery. A severe gastroparesis prolonged for 2 months after cytoreductive surgery in an advanced ovarian cancer patient was successfully treated with conservative multidrug therapy. Gastroparesis has to be enumerated as a rare but possible event after major gynecological oncologic surgery. A conservative management involving decompressive nasogastric tube, nutritional support, antiemetic drugs, prokinetic drugs is suggested, while surgical therapy is only recommended in a very small subset of unmanageable patients.

    Medicine has experienced greater scientific and technological advances in the last 50 years than in the rest of human history. The article describes relevant events, revises concepts and advantages and clinical applications, summarizes published clinical results, and presents some personal reflections without giving dogmatic conclusions about robotic surgery. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) defines robotic surgery as a surgical procedure using technology to aid the interaction between surgeon and patient. The objective of the surgical robot is to correct human deficiencies and improve surgical skills. The capacity of repeating tasks with precision and reproducibility has been the base of the robot´s success. Robotic technology offers objective and measurable advantages: - Improving maneuverability and physical capacity during surgery. - Correcting bad postural habits and tremor. - Allowing depth perception (3D images). - Magnifying strength and movement limits. - Offering a platform for sensors, cameras, and instruments. Endoscopic surgery transformed conceptually the way of practicing surgery. Nevertheless in the last decade, robotic assisted surgery has become the next paradigm of our era.

    The WHO describes health as physical, mental and social well being. Ever since the establishment of plastic surgery aesthetic surgery has been an integral part of this medical specialty. It aims at reconstructing subjective well-being by employing plastic surgical procedures as described in the educational code and regulations for specialists of plastic surgery. This code confirms that plastic surgery comprises cosmetic procedures for the entire body that have to be applied in respect of psychological exploration and selection criteria. A wide variety of opinions resulting from very different motivations shows how difficult it is to differentiate aesthetic surgery as a therapeutic procedure from beauty surgery as a primarily economic service. Jurisdiction, guidelines for professional conduct and ethical codes have tried to solve this question. Regardless of the intention and ability of the health insurances, it has currently been established that the moral and legal evaluation of advertisements for medical procedures depends on their purpose: advertising with the intent of luring patients into cosmetic procedures that do not aim to reconstruct a subjective physical disorder does not comply with a medical indication. If, however, the initiative originates with the patient requesting the amelioration of a subjective disorder of his body, a medical indication can be assumed.

    Breast cancer is the leading oncological cause of death in Mexican women over 25 years old. Given the need to improve postoperative cosmetic results in patients with breast cancer, oncoplastic surgery has been developed, which allows larger tumour resections and minor cosmetic alterations. To determine the oncological feasibility and cosmetic outcome of oncoplastic surgery at the Instituto de Enfermedades de la Mama, FUCAM, AC. A review was conducted from January 2010 to July 2013, which included patients with breast cancer diagnosis treated with conventional breast-conserving surgery or with oncoplastic surgery in the Institute of Diseases of the Breast, FUCAM AC. Clinical and histopathological parameters were compared between the two groups, and a questionnaire of cosmetic satisfaction and quality of life was applied. Of the 171 patients included, 95 of them were treated with conventional breast-conserving surgery and 76 with oncoplastic surgery. Pathological tumour size was significantly larger in patients treated with oncoplastic surgery (p = 0.002). There were no differences found between the groups as regards the number of patients with positive surgical margin, the rate of complications, and cosmetic satisfaction. This study demonstrates the oncological feasibility and high cosmetic satisfaction of oncoplastic surgery with minimal psycho-social impact on patients.

    Purpose: Quality cancer care is best delivered through a multidisciplinary approach requiring awareness of current evidence for all oncologic specialties. The highest impact journals often disseminate such information, so the distribution and characteristics of oncology studies by primary intervention (local therapies, systemic therapies, and targeted agents) were evaluated in 10 high-impact journals over a 20-year period. Methods and Materials: Articles published in 1994, 2004, and 2014 in New England Journal of Medicine, Lancet, Journal of the American Medical Association, Lancet Oncology, Journal of Clinical Oncology, Annals of Oncology, Radiotherapy and Oncology, International Journal of Radiation Oncology, Biology, Physics, Annals of Surgical Oncology, and European Journal of Surgical Oncology were identified. Included studies were prospectively conducted and evaluated a therapeutic intervention. Results: A total of 960 studies were included: 240 (25%) investigated local therapies, 551 (57.4%) investigated systemic therapies, and 169 (17.6%) investigated targeted therapies. More local therapy trials (n=185 [77.1%]) evaluated definitive, primary treatment than systemic (n=178 [32.3%]) or targeted therapy trials (n=38 [22.5%]; P<.001). Local therapy trials (n=16 [6.7%]) also had significantly lower rates of industry funding than systemic (n=207 [37.6%]) and targeted therapy trials (n=129 [76.3%]; P<.001). Targeted therapy trials represented 5 (2%), 38 (10.2%), and 126 (38%) of those published in 1994, 2004, and 2014, respectively (P<.001), and industry-funded 48 (18.9%), 122 (32.6%), and 182 (54.8%) trials, respectively (P<.001). Compared to publication of systemic therapy trial articles, articles investigating local therapy (odds ratio: 0.025 [95% confidence interval: 0.012-0.048]; P<.001) were less likely to be found in high-impact general medical journals. Conclusions: Fewer studies evaluating local therapies, such as surgery and radiation, are published in

  12. Current advances in liver surgery

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Hepatobiliary surgery has taken a big step forward in recent decades especially in the minimally invasive approach for hepatectomy. From being sceptical at the beginning of the 1990s when laparoscopic surgery had become prevalent, to now, where laparoscopic hepatectomy has been well-established, especially in minor hepatectomies; this new technique has evolved rapidly over the past 20-years demonstrating better short-term outcomes and equivalent oncological outcomes in selected patients and in expert hands. Laparoscopic hepatectomy is indeed, more difficult to master than the open procedure with restrictions in working space, difficulty in haemostasis and the potential risk of gas embolism. However, with better visibility of the operative field around the liver, especially beneath the costal margin, the magnified view and theoretical advantage of pneumoperitoneum acting as haemostatic pressure have made laparoscopic hepatectomy increasingly popular. Another important advancement is the new surgical technique of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS. This procedure induces more rapid liver hypertrophy within a median period of 9-days, allowing resection to be performed in candidates with borderline functional liver remnant and at an earlier date. However, studies have shown that ALPPS is associated with a relatively higher rate of morbidity and mortality. Therefore, it remains a highly controversial treatment option and more studies have to be performed to establish its usefulness and define its role in liver surgery.

    Full Text Available Introduction. Glottic carcinoma can be successfully diagnosed in its early stages and treated with high percentage of success. Organ preservation and optimal functional outcomes could be achieved with wide array of surgical techniques for early glottic cancer, including endoscopic approaches or open laryngeal preserving procedures, making surgery the preferred method of treatment of early glottic carcinoma in the last few years. Material and Methods. Prospective study was done on 59 patients treated for Tis and T1a glottic carcinoma over a one-year time period in a tertiary medical center. Patients were treated with endoscopic laser cordectomy (types II–IV cordectomies according to European Laryngological Society classification of endoscopic cordectomies and open cordectomy through laryngofissure. Follow-up period was 60 months. Clinical and oncological results were followed postoperatively. Voice quality after the treatment was assessed using multidimensional voice analysis 12 months after the treatment. Results. There were no significant differences between oncological and functional results among two groups of patients, though complications were more frequent in patients treated with open cordectomy. Conclusion. Endoscopic laser surgery should be the first treatment of choice in treatment of early glottic carcinomas, though open approach through laryngofissure should be available for selected cases where anatomical factors present limiting adequate tumor removal.

    To report a fuzzy logic mathematical model to predict postoperative vomiting (POV) in pediatric oncologic patients and compare with preexisting scores. Although POV has a high incidence in children and may decrease parental satisfaction after surgeries, there is only one specific score that predicts POV in children: the Eberhart's score. In this study, we report a fuzzy model that intends to predict the probability of POV in pediatric oncologic patients. Fuzzy logic is a mathematical theory that recognizes more than simple true and false values and takes into account levels of continuous variables such as age or duration of the surgery. The fuzzy model tries to account for subjectiveness in the variables. Preoperative potential risk factors for POV in 198 children (0-19 year old) with malignancies were collected and analyzed. Data analysis was performed with the chi-square test and logistic regression to evaluate probable risk factors for POV. A system based on fuzzy logic was developed with the risk factors found in the logistic regression, and a computational interface was created to calculate the probability of POV. The model showed a good performance in predicting POV. After the analysis, the model was compared with Eberhart's score in the same population and showed a better performance. The fuzzy score can predict the chance of POV in children with cancer with good accuracy, allowing better planning for postoperative prophylaxis of vomiting. The computational interface is available for free download at the internet and is very easy to use. © 2012 Blackwell Publishing Ltd.

    The Oncology Education Initiative was created to advance oncology and radiation oncology education by integrating structured didactics into the existing core radiology clerkship. We set out to determine whether the addition of structured didactics could lead to a significant increase in overall medical student knowledge about radiation oncology. We conducted a pre- and posttest examining concepts in general radiation oncology, breast cancer, and prostate cancer. The 15-question, multiple-choice exam was administered before and after a 1.5-hour didactic lecture by an attending physician in radiation oncology. Individual question changes, overall student changes, and overall categorical changes were analyzed. All hypothesis tests were two-tailed (significance level 0.05). Of the 153 fourth-year students, 137 (90%) took the pre- and posttest and were present for the didactic lecture. The average test grade improved from 59% to 70% (p = 0.011). Improvement was seen in all questions except clinical vignettes involving correct identification of TNM staging. Statistically significant improvement (p cancer, delivery of radiation treatment, and management of early-stage breast cancer. Addition of didactics in radiation oncology significantly improves medical students' knowledge of the topic. Despite perceived difficulty in teaching radiation oncology and the assumption that it is beyond the scope of reasonable knowledge for medical students, we have shown that even with one dedicated lecture, students can learn and absorb general principles regarding radiation oncology.

    Proficiency in minimally invasive surgery requires intensive and continuous training, as it is technically challenging for unnatural visual and haptic perceptions. Robotic and computer sciences are producing innovations to augment the surgeon's skills to achieve accuracy and high precision during complex surgery. This article reviews the current use of robotically assisted surgery, focusing on technology as well as main applications in digestive surgery, and future perspectives. The PubMed database was interrogated to retrieve evidence-based data on surgical applications. Internal and external consulting with key opinion leaders, renowned robotics laboratories and robotic platform manufacturers was used to produce state-of-the art business intelligence around robotically assisted surgery. Selected digestive procedures (oesophagectomy, gastric bypass, pancreatic and liver resections, rectal resection for cancer) might benefit from robotic assistance, although the current level of evidence is insufficient to support widespread adoption. The surgical robotic market is growing, and a variety of projects have recently been launched at both academic and corporate levels to develop lightweight, miniaturized surgical robotic prototypes. The magnified view, and improved ergonomics and dexterity offered by robotic platforms, might facilitate the uptake of minimally invasive procedures. Image guidance to complement robotically assisted procedures, through the concepts of augmented reality, could well represent a major revolution to increase safety and deal with difficulties associated with the new minimally invasive approaches. © 2015 BJS Society Ltd.

    Graiff, Claudio

    2014-10-01

    Donatori di Musica is a network of musicians - both physicians and volunteers - that was initially founded in 2009 with the aim to set up and coordinate classical music concerts in hospitals. This activity was initially started and led by the Oncology Departments at Carrara and Bolzano Hospitals, where high profile professional musicians make themselves available for concerts in support of Oncological in/out-patients of that specific Hospital. A live classical music performance is a deeply touching experience - particularly for those who live a critical condition like cancer. Main characteristics of Donatori di Musica concerts are: continuity (concerts are part of a regular and non-stopping music season); quality (concerts are held by well-established professional musicians); philanthropic attitude (musicians do not wear a suit and usually chat with patients; they also select an easy-to-listen program; a convivial event is usually organized after the performance with the aim of overcoming distinctions and barriers between physician and patient); no profit: musicians perform for free - travel expenses and/or overnight staying only can be claimed; concerts have free access for patients, their families and hospital staff.Patients and musicians therefore do get in close contact and music is able to merge each other experiences - with patients being treated by the beauty of music and musicians being treated theirselves by patients daily-life feedback. The Donatori di Musica experience is therefore able to help Medicine to retrieve its very first significance - the medical act regain that human and cultural dimension that seems to be abandoned in the last decades in favour of a mere technicism. This is the spirit and the deep significance of Donatori di Musica - «[…] the hope that Music can become a key support to medical treatments in every Oncology department» (by Gian Andrea Lodovici).

  18. Laparoscopic rectal cancer surgery: Where do we stand?

    2012-01-01

    Large comparative studies and multiple prospective randomized control trials (RCTs) have reported equivalence in short and long-term outcomes between the open and laparoscopic approaches for the surgical treatment of colon cancer which has heralded widespread acceptance for laparoscopic resection of colon cancer.In contrast,laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer has been welcomed with significantly less enthusiasm.While it is likely that patients with rectal cancer will experience the same benefits of early recovery and decreased postoperative pain from the laparoscopic approach,whether the same oncologic clearance,specifically an adequate TME can be obtained is of concern.The aim of the current study is to review the current level of evidence in the literature on laparoscopic rectal cancer surgery with regard to short-term and long-term oncologic outcomes.The data from 8 RCTs,3 metaanalyses,and 2 Cochrane Database of Systematic Reviews was reviewed.Current data suggests that laparoscopic rectal cancer resection may benefit patients with reduced blood loss,earlier retum of bowel function,and shorter hospital length of stay.Concerns that laparoscopic rectal cancer surgery compromises shortterm oncologic outcomes including number of lymph nodes retrieved and circumferential resection margin and jeopardizes long-term oncologic outcomes has not conclusively been refuted by the available literature.Laparoscopic rectal cancer resection is feasible but whether or not it compromises short-term or long-term results still needs to be further studied.

    The value of magnetic resonance (MR) imaging for the clinical management of brain tumour patients has greatly increased in recent years through the introduction of functional MR sequences. Previously, MR imaging for brain tumours relied for the most part on contrast-enhanced T1-weighted MR sequences but today with the help of advanced functional MR sequences, the pathophysiological aspects of tumour growth can be directly visualised and investigated. This article will present the pathophysiological background of the MR sequences relevant to neuro-oncological imaging as well as potential clinical applications. Ultimately, we take a look at possible future developments for ultra-high-field MR imaging.

    2018-01-01

    Personalized medicine is a keyword in modern oncology summarizing biomarker-driven targeted therapies. Those novel agents enhance our therapeutic portfolio and offer new options for our patients. But the term is often misleading and implicates a tailored therapy to the individual person, but it rather means a treatment stratified on genetic characteristics of the tumor. Molecular therapies raise expectations of curability or long-term treatments making former life-threatening diseases to more chronic ones but this is true only for some patients. So we have to carefully communicate with our patients about the options and limitations of those modern therapies not to trigger disappointments.

    This article outlines the expanding approaches to whole-body imaging in oncology focusing on whole-body MRI and comparing it to emerging applications of whole-body CT, scintigraphy, and above all PET CT imaging. Whole-body MRI is widely available, non-ionizing and rapidly acquired, and inexpensive relative to PET CT. While it has many advantages, WBMRI is non-specific and, when compared to PET CT, is less sensitive. This article expands each of these issues comparing individual modalities as they refer to specific cancers.

    Nanomedicine is based on the fact that biological molecules behave similarly to nanomolecules, which have a size of less than 100 nm, and is now affecting most areas of orthopedics. In orthopedic oncology, most of the in vitro and in vivo studies have used osteosarcoma or Ewing sarcoma cell lineages. In this article, tumor imaging and treatment nanotechnology applications, including nanostructure delivery of chemotherapeutic agents, gene therapy, and the role of nano-selenium-coated implants, are outlined. Finally, the potential role of nanotechnology in addressing the challenges of drug and radiotherapy resistance is discussed. [Orthopedics. 2016; 39(5):280-286.].

    Full Text Available Introduction. Transoral robotic surgery is a step forward in the evolution of minimally invasive surgery in the head and neck, optimizing the two basic requirements of such surgical approaches: excellent vision and freedom of handling. Its development since 2009 has been explosive. Materials and Methods. We describe the technical aspects of the da Vinci robotic surgery system and the basic surgical procedures (radical tonsillectomy, resection of the tongue base and supraglottic laryngectomy. Through a literature review we present the available clinical experience .Results. Transoral robotic surgery has been applied mainly for head and neck cancer. Large enough series have been published with functional and oncological results, which are comparable to those with the standard techniques. Robotic surgery particularly widens the possibilities for the transoral approach to the oropharynx. The surgical approach to the base of the tongue also opens new possibilities in the management of sleep apnea. The robotic approaches to the skull base are still experimental. Discussion. Available data support the use of transoral robotic surgery and prompt towards substantial changes in the management protocols for head and neck cancer.

    More than a decade ago, robotic surgery was introduced into urology. Since then, the urological community started to look at surgery from a different angle. The present, the future hopes, and the way we looked at our past experience have all changed. Between 2000 and 2011, the published literature was reviewed using the National Library of Medicine database and the following key words: robotic surgery, robot-assisted, and radical prostatectomy. Special emphasis was given to the impact of the robotic surgery in urology. We analyzed the most representative series (finished learning curve) in each one of the robotic approaches regarding perioperative morbidity and oncological outcomes. This article looks into the impact of robotics in urology, starting from its background applications before urology, the way it was introduced into urology, its first steps, current status, and future expectations. By narrating this journey, we tried to highlight important modifications that helped robotic surgery make its way to its position today. We looked as well into the dramatic changes that robotic surgery introduced to the field of surgical training and its consequence on its learning curve. Basic surgical principles still apply in Robotics: experience counts, and prolonged practice provides knowledge and skills. In this way, the potential advantages delivered by technology will be better exploited, and this will be reflected in better outcomes for patients. Copyright © 2012 AEU. Published by Elsevier Espana.

    Modern medicine, which is evidence-based and overly scientific, has forgotten its artistic component, which is very important for surgery in general and for geriatric surgery in particular. The surgeon treating an old patient must be a politician more than a technician, more an artist than a scientist. Like Leonardo da Vinci, he or she must use scientific knowledge with intelligence and sensitivity, transforming the elderly patient's last days of life into a beautiful and harmonious painting and not into something like an atomic power station which, while no doubt useful, is deprived of beauty and sometimes very dangerous.

  11. Robotic Surgery in Gynecology: An Updated Systematic Review

    Directory of Open Access Journals (Sweden)

    Lori Weinberg

    2011-01-01

    Full Text Available The introduction of da Vinci Robotic Surgery to the field of Gynecology has resulted in large changes in surgical management. The robotic platform allows less experienced laparoscopic surgeons to perform more complex procedures. In general gynecology and reproductive gynecology, the robot is being increasingly used for procedures such as hysterectomies, myomectomies, adnexal surgery, and tubal anastomosis. Among urogynecology the robot is being utilized for sacrocolopexies. In the field of gynecologic oncology, the robot is being increasingly used for hysterectomies and lymphadenectomies in oncologic diseases. Despite the rapid and widespread adoption of robotic surgery in gynecology, there are no randomized trials comparing its efficacy and safety to other traditional surgical approaches. Our aim is to update previously published reviews with a focus on only comparative observational studies. We determined that, with the right amount of training and skill, along with appropriate patient selection, robotic surgery can be highly advantageous. Patients will likely have less blood loss, less post-operative pain, faster recoveries, and fewer complications compared to open surgery and potentially even laparoscopy. However, until larger, well-designed observational studies or randomized control trials are completed which report long-term outcomes, we cannot definitively state the superiority of robotic surgery over other surgical methods.

    PURPOSE The value of exercise and rehabilitative interventions for cancer survivors is increasingly clear and oncology rehabilitation programs could provide these important interventions. However, a pathway to create oncology rehabilitation has not been delineated. Community-based cardiac rehabilitation (CR) programs staffed by health care professionals with experience in providing rehabilitation and secondary prevention services to individuals with coronary heart disease are widely available and provide a potential model and location for oncology rehabilitation programs. Our purpose is to outline the rehabilitative needs of cancer survivors and demonstrate how oncology rehabilitation can be created using a cardiac rehabilitation model. METHODS We identify the impairments associated with cancer and its therapy that respond to rehabilitative interventions. Components of the CR model that would benefit cancer survivors are described. An example of an oncology rehabilitation program using a CR model is presented. RESULTS Cancer survivors have impairments associated with cancer and its therapy that improve with rehabilitation. Our experience demonstrates that effective rehabilitation services can be provided utilizing an existing CR infrastructure. Few adjustments to current cardiac rehabilitation models would be needed to provide oncology rehabilitation. Preliminary evidence suggests that cancer survivors participating in an oncology rehabilitation program experience improvements in psychological and physiologic parameters. CONCLUSIONS Utilizing the CR model of rehabilitative services and disease management provides a much needed mechanism to bring oncology rehabilitation to larger numbers of cancer survivors.

    Objective. To explore use of pharmacy learners as a means to expand pharmacy services in a layered learning practice model (LLPM), to examine whether an LLPM environment precludes achievement of knowledge-based learning objectives, and to explore learner perception of the experience. Design. An acute care oncology pharmacy practice experience was redesigned to support the LLPM. Specifically, the redesign focused on micro discussion, standardized feedback (eg, rubrics), and cooperative learning to enhance educational gain through performing clinical activities. Assessment. Posttest scores evaluating knowledge-based learning objectives increased in mean percentage compared to pretest values. Learners viewed the newly designed practice experience positively with respect to perceived knowledge attainment, improved clinical time management skills, contributions to patient care, and development of clinical and self-management skills. A fifth theme among students, comfort with learning, was also noted. Conclusion. Layered learning in an oncology practice experience was well-received by pharmacy learners. Data suggest a practice experience in the LLPM environment does not preclude achieving knowledge-based learning objectives and supports further studies of the LLPM.

  4. Combined PET/CT in oncology

    2002-02-01

    Presently, PET is widely used in oncology, but suffers from limitations of poor anatomical information. To compensate for this weakness, a combined PET/CT has been developed by Professor Townsend at the University of Pittsburgh Medical Center. The prototype was designed as PET and CT components combined serially in a gantry. The CT images provide not only accurate anatomical location of the lesions but also transmission map for attenuation correction. More than 300 cancer patients have been studied with the prototype of PET/CT since July, 1998. The PET/TC studies affected the managements in about 20{approx}30% of cancer patients. These changes are a consequence of the more accurate localization of functional abnormalities, and the distinction of pathological from normal physiological uptake. Now a variety of combined PET/CT scanners with high-end PET and high-end CT components are commercially available. With the high speed of multi-slice helical CT, throughput of patient's increases compared to conventional PET. Although some problems (such as a discrepancy in breathing state between the two modalities) still remain, the role of PET/CT in oncology is very promising.

    Medical physics, an applied field of physics, is the applications of physics in medicine. Medical physicists are essential professionals in contemporary healthcare, contributing primarily to the diagnosis and treatment of diseases through numerous inventions, advances, and improvements in medical imaging and cancer treatment. Clinical service, research, and teaching by medical physicists benefits thousands of patients and other individuals every day. This talk will cover three main topics. First, exciting current research and development areas in the medical physics sub-specialty of radiation oncology physics will be described, including advanced oncology imaging for treatment simulation, image-guided radiation therapy, and biologically-optimized radiation treatment. Challenges in patient safety in high-technology radiation treatments will be briefly reviewed. Second, the educational path to becoming a medical physicist will be reviewed, including undergraduate foundations, graduate training, residency, board certification, and career opportunities. Third, I will introduce the American Association of Physicists in Medicine (AAPM), which is the professional society that represents, advocates, and advances the field of medical physics (www.aapm.org).

    Many practitioners in oncology receive no or little training in how to effectively communicate with patients and families who are dealing with cancer. Moreover medical teachers are not always aware of the pedagogy of teaching communication skills in a way that results in performance improvement in this area. In this paper a method of small group teaching that was used to instruct medical oncology fellows in the essentials of communication using a retreat format that lasted three days is described. The paper covers the theoretical basis for the teaching format as well as the specific components of the workshops. It describes the process of facilitation using a "learner-centered" approach using standardized patients who take on the role of cancer patients along the trajectory of the illness. It discuss the use of small group process to facilitate skills acquisition and other strategies that facilitate learning such as reflective exercises, open role play and parallel process. It concludes with a consideration of the various ways that such workshops can be evaluated.

    Burnout is an important occupational problem for health care workers. We aimed to assess the burnout levels among oncology employees and to evaluate the sociodemographic and occupational factors contributing to burnout levels. The Maslach Burnout Inventory, which is designed to measure the three stages of burnout-emotional exhaustion (EE), depersonalization (DP), and personal accomplishment (PA), was used. The study sample consisted of 90 participants with a median age of 34 (range 23-56). The mean levels of burnout in EE, DP and PA stages were 23.80 +/- 10.98, 5.21 +/- 4.99, and 36.23 +/- 8.05, respectively, for the entire sample. Among the 90 participants, 42, 20, and 35.6% of the employees had high levels of burnout in the EE, DP, and PA substage, respectively. Sociodemographic and occupational factors associated with higher levels of burnout included age of less than 35, being unmarried, being childless, >40 work hours per week, working on night shifts, and burnout. Furthermore, employees who are not pleased with working in oncology field, who would like to change their specialty if they have an opportunity, and whose family and social lives have been negatively affected by their work experienced higher levels of burnout. Burnout syndrome may influence physical and mental health of the employee and affects the quality of health care as well. Therefore, several individual or organizational efforts should be considered for dealing with burnout.

    Radiation oncology is one of the three major treatment modalities to manage cancer patient cares, and is a discipline mainly driven by technology and medical devices. Modern radiation treatments have become fairly complex and involve in utilizing a variety of medical devices to achieve the goal of providing conformal radiation dose coverage to the tumor target(s) while maximizing the sparing of normal organ structures. Recently, different forms of linear accelerators/radioactive source based machines have been invented and developed with the aim of providing improved treatments and more treatment options. Besides linear accelerators (Linac) that have been undergoing constant improvement and advancement and can deliver fairly complicated dose distribution patterns, imaging systems, computer information and calculation systems have been more and more integrated into radiotherapy processes. To bring radiotherapy to a potentially higher level, many institutions have either acquired or started to consider particle therapy, especially proton therapy. The complexity of modern radiotherapy demands in-depth understanding of radiation physics and machine engineering as well as computer information systems. This paper is intended to provide an introductory description of radiation oncology and related procedures, and to provide an overview of the current status of medical devices in radiotherapy in the United States of America. This paper covers the radiation delivery systems, imaging systems, treatment planning systems, record and verify systems, and QA systems.

    Health care professionals do not have emotional labour obligations in their employment contract. However, in everyday work it is often inevitable for them to change their true feelings. This is critically true for professionals treating chronic or cancer patients. The suitable emotional state of the treatment staff does not only influence the practitioner-patient relationship but the process of recovery as well. Depending on the way one might get into the appropriate emotional state, the literature distinguishes between surface, deep and genuine acting. While surface and deep emotional labour has numerous negative psychological consequences genuine acting is usually accompanied by positive side effects. For those working in the field of oncology, emotional labour is a part of the role expectations of the professionals. This is how the appropriate attitude is a fundamental part of the professionals' essence. For the in depth analysis of subjects related to emotional labour, the authors adopted ideas from L. Festinger 's cognitive dissonance theory. The best way to alleviate cognitive dissonance and the negative side effects of emotional labour is to prevent the emergence of them. Oncology professionals should fit their role expectations genuinely, without particular efforts. If this was impossible, or the particular life situations did not allow genuine acting, it is the employer's and the workmates' common duty to help professionals, to ease the load of emotional labour, to diminish the occurring cognitive dissonance with the help of appropriate recompense.

  11. Molecular markers in pediatric neuro-oncology.

    2012-09-01

    Pediatric molecular neuro-oncology is a fast developing field. A multitude of molecular profiling studies in recent years has unveiled a number of genetic abnormalities unique to pediatric brain tumors. It has now become clear that brain tumors that arise in children have distinct pathogenesis and biology, compared with their adult counterparts, even for those with indistinguishable histopathology. Some of the molecular features are so specific to a particular type of tumors, such as the presence of the KIAA1549-BRAF fusion gene for pilocytic astrocytomas or SMARCB1 mutations for atypical teratoid/rhabdoid tumors, that they could practically serve as a diagnostic marker on their own. Expression profiling has resolved the existence of 4 molecular subgroups in medulloblastomas, which positively translated into improved prognostication for the patients. The currently available molecular markers, however, do not cover all tumors even within a single tumor entity. The molecular pathogenesis of a large number of pediatric brain tumors is still unaccounted for, and the hierarchy of tumors is likely to be more complex and intricate than currently acknowledged. One of the main tasks of future molecular analyses in pediatric neuro-oncology, including the ongoing genome sequencing efforts, is to elucidate the biological basis of those orphan tumors. The ultimate goal of molecular diagnostics is to accurately predict the clinical and biological behavior of any tumor by means of their molecular characteristics, which is hoped to eventually pave the way for individualized treatment.

    Performing randomised comparative clinical trials in radiation oncology remains a challenge when new treatment modalities become available. One of the most recent examples is the lack of phase III trials demonstrating the superiority of intensity-modulated radiation therapy in most of its current indications. A new paradigm is developing that consists in the mining of large databases to answer clinical or translational issues. Beyond national databases (such as SEER or NCDB), that often lack the necessary level of details on the population studied or the treatments performed, electronic health records can be used to create detailed phenotypic profiles of any patients. In parallel, the Record-and-Verify Systems used in radiation oncology precisely document the planned and performed treatments. Artificial Intelligence and machine learning algorithms can be used to incrementally analyse these data in order to generate hypothesis to better personalize treatments. This review discusses how these methods have already been used in previous studies. Copyright © 2017 Société française de radiothérapie oncologique (SFRO). Published by Elsevier SAS.

    Delivering a cohesive oncology curriculum to medical students is challenging due to oncology's multidisciplinary nature, predominantly outpatient clinical setting, and lack of data describing effective approaches to teaching it. We sought to better characterize approaches to oncology education at US medical schools by surveying third and fourth year medical students who serve on their institution's curriculum committee. We received responses from students at 19 schools (15.2% response rate). Key findings included the following: (1) an under-emphasis of cancer in the curriculum relative to other common diseases; (2) imbalanced involvement of different clinical subspecialists as educators; (3) infrequent requirements for students to rotate through non-surgical oncologic clerkships; and (4) students are less confident in their knowledge of cancer treatment compared to basic science/natural history or workup/diagnosis. Based on these findings, we provide several recommendations to achieve robust multidisciplinary curriculum design and implementation that better balances the clinical and classroom aspects of oncology education.

    Systemic therapy is one of the cornerstones of cancer treatment. In 1972, following representations by American Society of Clinical Oncology (ASCO), the American Board of Internal Medicine (ABIM) recognized medical oncology as a new subspecialty of internal medicine. Subspecialty of Hematology and Medical Oncology was emerged in Iran in 1983. In the past, modern medical treatments and education were started in Dar Al-fonun school and then in Tehran University; now six universities in Iran are training in Subspecialty of Hematology and Medical Oncology. There are also ten active hematopoietic stem cell transplantation centers, thirty-one provincial medical schools use their specialized services. Future goals for Hematology and Medical Oncology in Iran include expansion and reinforcement of multidisciplinary teams across the country, early detection and prevention of cancer, providing educational program and conducting cancer researches. To achieve these goals, it is necessary to establish Cancer Hospitals in each province that link together through a network.

    Purpose: To promote the rational use of scarce research funding, scholars have developed methods for the systematic identification and prioritization of health research needs. The Radiation Oncology Institute commissioned an independent, comprehensive assessment of research needs for the advancement of radiation oncology care. Methods and Materials: The research needs assessment used a mixed-method, qualitative and quantitative social scientific approach, including structured interviews with diverse stakeholders, focus groups, surveys of American Society for Radiation Oncology (ASTRO) members, and a prioritization exercise using a modified Delphi technique. Results: Six co-equal priorities were identified: (1) Identify and develop communication strategies to help patients and others better understand radiation therapy; (2) Establish a set of quality indicators for major radiation oncology procedures and evaluate their use in radiation oncology delivery; (3) Identify best practices for the management of radiation toxicity and issues in cancer survivorship; (4) Conduct comparative effectiveness studies related to radiation therapy that consider clinical benefit, toxicity (including quality of life), and other outcomes; (5) Assess the value of radiation therapy; and (6) Develop a radiation oncology registry. Conclusions: To our knowledge, this prioritization exercise is the only comprehensive and methodologically rigorous assessment of research needs in the field of radiation oncology. Broad dissemination of these findings is critical to maximally leverage the impact of this work, particularly because grant funding decisions are often made by committees on which highly specialized disciplines such as radiation oncology are not well represented.

    The pace of innovation in radiation oncology is high and the window of opportunity for evaluation narrow. Financial incentives, industry pressure, and patients' demand for high-tech treatments have led to widespread implementation of innovations before, or even without, robust evidence of improved outcomes has been generated. The standard phase I-IV framework for drug evaluation is not the most efficient and desirable framework for assessment of technological innovations. In order to provide a standard assessment methodology for clinical evaluation of innovations in radiotherapy, we adapted the surgical IDEAL framework to fit the radiation oncology setting. Like surgery, clinical evaluation of innovations in radiation oncology is complicated by continuous technical development, team and operator dependence, and differences in quality control. Contrary to surgery, radiotherapy innovations may be used in various ways, e.g., at different tumor sites and with different aims, such as radiation volume reduction and dose escalation. Also, the effect of radiation treatment can be modeled, allowing better prediction of potential benefits and improved patient selection. Key distinctive features of R-IDEAL include the important role of predicate and modeling studies (Stage 0), randomization at an early stage in the development of the technology, and long-term follow-up for late toxicity. We implemented R-IDEAL for clinical evaluation of a recent innovation in radiation oncology, the MRI-guided linear accelerator (MR-Linac). MR-Linac combines a radiotherapy linear accelerator with a 1.5-T MRI, aiming for improved targeting, dose escalation, and margin reduction, and is expected to increase the use of hypofractionation, improve tumor control, leading to higher cure rates and less toxicity. An international consortium, with participants from seven large cancer institutes from Europe and North America, has adopted the R-IDEAL framework to work toward coordinated, evidence

    With process optimization and technical innovation, laparoscopic gastrointestinal surgery has evolved dramatically over the last two decades and provided important improvement in the contemporary surgical practice and patients' recovery. With the emergence of many new minimally invasive technologies, including total laparoscopic surgery, single-incision laparoscopic surgery, and natural orifice specimen extraction, patents with gastrointestinal carcinomas may experience less pain and have lower perioperative complications, but the exact efficacy remains to be proven. Large-scale international multi-centre randomized controlled trial data have revealed that laparoscopic colorectal surgery is safe both in terms of short-term perioperative outcomes and long-term oncological efficacy. However, the question whether there is an equivalent oncological outcome compared to the open approach in gastric cancer is still unanswered by now and needs to be proven by future studies.

    In December 2016, the American Society of Clinical Oncology (ASCO) Board of Directors approved the ASCO Strategic Plan to Increase Racial and Ethnic Diversity in the Oncology Workforce. Developed through a multistakeholder effort led by the ASCO Health Disparities Committee, the purpose of the plan is to guide the formal efforts of ASCO in this area over the next three years (2017 to 2020). There are three primary goals: (1) to establish a longitudinal pathway for increasing workforce diversity, (2) to enhance ASCO leadership diversity, and (3) to integrate a focus on diversity across ASCO programs and policies. Improving quality cancer care in the United States requires the recruitment of oncology professionals from diverse backgrounds. The ASCO Strategic Plan to Increase Racial and Ethnic Diversity in the Oncology Workforce is designed to enhance existing programs and create new opportunities that will move us closer to the vision of achieving an oncology workforce that reflects the demographics of the US population it serves.

    Role expansion recognises enlargement of existing scope of practice within radiation therapy (RT). Over the past decade, there has been increasing involvement and movement towards advanced practice in the form of role extension in specialised areas of practice including brachytherapy, image fusion and quality assurance. It is also recognised that radiation therapy expert practitioners exist in the areas of imaging immobilisation, treatment, education and research. The acquisition of additional skills has hastened the need for autonomy within the RT profession and with this comes the responsibility to share our knowledge and specialist abilities with the wider community. Radiation therapy is a highly specialised profession working to treat a commonly encountered ailment like cancer and we should ask ourselves what other community members could benefit from our knowledge and skills. Cancer is not limited to the human population but affects animals as readily and severely. Particular types of cancers have been identified as being comparable with that of humans; one such tumour is squamous cell carcinoma (SCC). Squamous cell carcinoma is the most commonly found tumour of the eye and adnexa in horses. Comparatively, SCC in humans is the most common cancer in Australia. Whilst human treatment is well established with surgery and radiation therapy offering comparable control rates, the treatment within Australia's Veterinary Oncology field is currently at a standstill. It is reported, however, that the use of interstitial brachytherapy has been shown to be highly effective and thoroughly practiced and established within the United States of America (USA). This paper reviews current literature in readiness for the potential for radiation therapy cross-over into the veterinary sphere with regard to the implementation of treatment and radiation safety protocols for the use of interstitial brachytherapy in horses.

    Death with dignity (DWD) refers to the refusal of life-prolonging measures for terminally ill patients by "living wills" forms in advance. More and more oncology physicians are receiving DWD requests from advance cancer patients in mainland China. The study objective was to investigate the attitudes of Chinese oncology physicians toward the legalization and implementation of DWD. A questionnaire investigating the understanding and attitudes toward DWD was administered to 257 oncology physicians from 11 hospitals in mainland China. The effective response rate was 86.8% (223/257). The majority of oncology physicians (69.1%) had received DWD requests from patients. Half of the participants (52.5%) thought that the most important reason was the patients' unwillingness to maintain survival through machines. One-third of participants (33.0%) attributed the most important reason to suffering from painful symptoms. Most oncology physicians (78.9%) had knowledge about DWD. A fifth of respondents did not know the difference between DWD and euthanasia, and a few even considered DWD as euthanasia. The majority of oncology physicians supported the legalization (88.3%) and implementation (83.9%) of DWD. Many Chinese oncology physicians have received advanced cancer patients' DWD requests and think that DWD should be legalized and implemented. Chinese health management departments should consider the demands of physicians and patients. It is important to inform physicians about the difference between DWD and euthanasia, as one-fifth of them were confused about it.

    2010-01-01

    With recent advances in medical and orthopedic oncology, radiation therapy and single- or multiple-agent perioperative chemotherapy are currently applied as an essential part of the multidisciplinary treatment to improve disease-free and overall survival of patients with primary and metastatic bone and soft tissue tumors. However, these treatments have led to unwanted complications. A better understanding of the effects of various antineoplastic agents on bone, soft tissue, and organs may provide the basis for the more efficacious use of antiproliferative drugs when fracture healing or allograft incorporation is required. This knowledge may also provide a rationale for concurrent treatment with drugs that protect against or compensate for adverse effects in osseous repair resulting from chemotherapy.

    Background Hepatocellular carcinoma (HCC) remains a major health issue because of its increasing incidence and because of the complexity of its management. In addition to the traditional potentially curative treatments, i.e., liver transplantation and surgical resection, other new and emerging local therapies have been applied with promising results. Summary Radiotherapy (RT) and interstitial treatments, such as radiofrequency ablation (RFA), microwave ablation (MWA), and irreversible electroporation (IRE), have recently opened new and interesting treatment scenarios for HCC and are associated with promising results in selected patients. Herein, we describe the emerging role of interventional oncology for the treatment of HCC and focus on the different Western and Eastern approaches. Key Messages Modern RT and modern interstitial therapies, such as RFA, MWA, and IRE, should be considered for inclusion in HCC therapy guidelines. PMID:27995086

    Cancer is currently one of the top non-communicable human diseases, and continual research and developmental efforts are being made to better understand and manage this disease. More recently, with the improved understanding in cancer biology as well as the advancements made in microtechnology and rapid prototyping, microfluidics is increasingly being explored and even validated for use in the detection, diagnosis and treatment of cancer. With inherent advantages such as small sample volume, high sensitivity and fast processing time, microfluidics is well-positioned to serve as a promising platform for applications in oncology. In this review, we look at the recent advances in the use of microfluidics, from basic research such as understanding cancer cell phenotypes as well as metastatic behaviors to applications such as the detection, diagnosis, prognosis and drug screening. We then conclude with a future outlook on this promising technology.

    Medical physics research is providing new avenues for addressing the fundamental problem of radiation therapy-how to provide a tumor-killing dose while reducing the dose to a non-lethal level for critical organs in adjacent portions of the patient anatomy. This talk reviews the revolutionary impact of Positron Emission Tomography on the practice of radiation oncology. The concepts of PET imaging and the development of "tumor" imaging methods using 18F-DG flouro-deoxyglucose are presented to provide the foundation for contemporary research and application to therapy. PET imaging influences radiation therapy decisions in multiple ways. Imaging of occult but viable tumor metastases eliminates misguided therapy attempts. The ability to distinguish viable tumor from scar tissue and necroses allows reduction of treatment portals and more selective treatments. Much research remains before the clinical benefits of these advances are fully realized.

    The Pivot Nurse in Oncology (PNO) is a health care professional dedicated to providing patients with cancer and their families with continuing and consistent supportive care throughout the care trajectory. The purpose of this paper is to describe the variation and frequency of nursing interventions delivered by 12 PNOs at our health centre. An administrative analysis over a three-year period revealed a total of 43,906 interventions that were grouped into 10 categories. This analysis provided a description of the intervention frequency and these interventions were further collapsed into the four role functions of the PNO. Coordination/continuity of care and the assessment of needs and symptoms were identified as the dominant practice domains of the PNO in the professional cancer navigator role.

    1999-01-01

    The paper considers whether it is advisable to use the new acting preparations adaptogens, including phytoadaptogens, in oncological care for prevention of cancer. The adaptogens are shown to have a regulating action, to be able to activate the protective properties of the body, to protect it from extreme exposures and to stimulate regenerative processes. The author associates the antitumor effect of adaptogens with the immunomodulating (they can activate macrophages, natural killer cells, antigen-dependent T lymphocytes) and interferonogenic actions and with the their ability to suppress experimental tumor growth, to enhance tissue differentiation, to improve intercellular adhesion, to reduce the likelihood of metastasis spreading. Furthermore, the use of adaptogens, and phytoadaptogens in particular, decreases the toxic effects of chemotherapy and improves drug tolerance.

The major challenge facing oncology is to achieve more selective, less toxic and effective methods of targeting disseminated tumors, a challenge oncolytic virotherapy may be well-placed to meet. Characterization of coxsackievirus A21 (CVA21 receptor-based mechanism of virus internalization and lysis in the last decade has suggested promise for CVA21 as a virotherapy against malignancies which overexpress those receptors. Preclinical studies have demonstrated proof of principle, and with the results of early clinical trials awaited, CVA21 may be one of the few viruses to demonstrate benefit for patients. This review outlines the potential of CVA21 as an oncolytic agent, describing the therapeutic development of CVA21 in preclinical studies and early stage clinical trials. Preclinical evidence supports the potential use of CVA21 across a range of malignancies. Malignant melanoma is the most intensively studied cancer, and may represent a “test case” for future development of the virus. Although there are theoretical barriers to the clinical utility of oncolytic viruses like CVA21, whether these will block the efficacy of the virus in clinical practice remains to be established, and is a question which can only be answered by appropriate trials. As these data become available, the rapid journey of CVA21 from animal studies to clinical trials may offer a model for the translation of other

    Pediatric hematology and oncology (PHO) is a rapidly expandingfield. It has been our goal to meet the needs and increasing demands for comprehensive medical care of children suffering from chronic blood diseases and malignancies. In the past decade we have been able expand and optimize the PHO services throughout Iran, in general and in respect to their prevalence and clinical importance, by trained pediatric hematologist-oncologists, pediatric surgeons and improved para clinical facilities. Major beta-thalassemics receive blood transfusion and chelation therapy according to the current standards mostly at regional blood banks centers. To curb major beta-thalassemia a premarital screening program has been enacted and abortion has been legitimized if major thalassemia is diagnosed by CVS. Hemophiliacs are supervised and treated as indicated by Iranian Hemophilia Comprehensive Care Centers (IHCCC). Screening for transfusion related complications and transmitted viral diseases (HBV, HCV and HIV) in both cohorts are carried out in regular intervals and necessary management will be then carried out as indicated at respective specialized units. Childhood malignancies are treated according to protocols adopted from accredited institutions in the USA and Europe, with almost comparable results. BMT is available for selected patients with beta-thalassemia or malignancies. By going to public we have been able to rise general awareness about chronic blood diseases and childhood malignancies and have initiated establishment of parents groups and formation of NGOs to support these children and their families. Foundation of Iranian Society of Pediatric Hamatology and Oncology (ISPHO) in the year 2000 has been another step forward to consolidate and coordinate the available manpower and facilities. By evaluation of the country's main problems and shortcomings and conduction of collaborative studies and operation planning one will succeed to get the expected feedback and

    To determine the quality of life (QoL) of breast cancer patients who underwent mastectomy and immediate breast reconstruction with a latissimus dorsi myocutaneous flap (LD), and the oncological safety of the procedure. Between May 2001 and March 2007, 2,566 patients had breast cancer surgery at the National Cancer Center, Korea. Of the 2,566 patients, 1,699 had breast-conserving surgery (BCS) and 120 had a mastectomy with an immediate LD. We retrospectively compared the oncologic safety of the two techniques. We also assessed the QoL using the EORTC QLQ BR-23 and Zung's self-rating depression scale in 52 LD patients, 104 age- and stage-matched patients who underwent BCS, and 104 age-matched healthy women. The LD group had earlier stage disease than the BCS group at baseline, but following surgery, the groups did not differ in the rates of local recurrence or systemic metastases. Compared with the healthy group, the patient groups had poorer functioning and more depression (p Mastectomy with immediate reconstruction should be considered carefully and tailored to the patient's needs and characteristics.

    Full Text Available Oncology nursing, like many other nursing fields, often provides nurses with the opportunity to get to know their patients and their families well. This familiarity allows oncology nurses to show a level of compassion and empathy that is often helpful to the patient and their family during their struggle with cancer. However, this familiarity can also lead to a profound sense of grief if the patient loses that struggle. This self-study provided me the opportunity to systematically explore my own experience with grief as an oncology nurse, helping me to identify specific stressors and also sources of stress release.

    Cardiovascular demands to the care of cancer patients are common and important given the implications for morbidity and mortality. As a consequence, interactions with cardiovascular disease specialists have intensified to the point of the development of a new discipline termed cardio-oncology. As an additional consequence, so-called cardio-oncology clinics have emerged, in most cases staffed by cardiologists with an interest in the field. This article addresses this gap and summarizes key points in the development of a cardio-oncology clinic.

    This Position Paper reviews the role, standards of practice, education, training and staffing requirements for radiation oncology physics. The role and standard of practice for an expert in radiation oncology physics, as defined by the ACPSEM, are consistent with the IAEA recommendations. International standards of safe practice recommend that this physics expert be authorised by a Regulatory Authority (in consultation with the professional organization). In order to accommodate the international and AHTAC recommendations or any requirements that may be set by a Regulatory Authority, the ACPSEM has defined the criteria for a physicist-in-training, a base level physicist, an advanced level physicist and an expert radiation oncology physicist. The ACPSEM shall compile separate registers for these different radiation oncology physicist categories. What constitutes a satisfactory means of establishing the number of physicists and support physics staff that is required in radiation oncology continues to be debated. The new ACPSEM workforce formula (Formula 2000) yields similar numbers to other international professional body recommendations. The ACPSEM recommends that Australian and New Zealand radiation oncology centres should aim to employ 223 and 46 radiation oncology physics staff respectively. At least 75% of this workforce should be physicists (168 in Australia and 35 in New Zealand). An additional 41 registrar physicist positions (34 in Australia and 7 in New Zealand) should be specifically created for training purposes. These registrar positions cater for the present physicist shortfall, the future expansion of radiation oncology and the expected attrition of radiation oncology physicists in the workforce. Registrar physicists shall undertake suitable tertiary education in medical physics with an organised in-house training program. The rapid advances in the theory and methodology of the new technologies for radiation oncology also require a stringent approach

    To quantify and determine the relationship between oncology departmental/division heads and private industry vis-à-vis potential financial conflict of interests (FCOIs) as publicly reported by the Centers for Medicare and Medicaid Services Open Payments database. We extracted the names of the chairs/chiefs in medical oncology (MO) and chairs of radiation oncology (RO) for 81 different institutions with both RO and MO training programs as reported by the Association of American Medical Colleges. For each leader, the amount of consulting fees and research payments received in 2015 was determined. Logistic modeling was used to assess associations between the 2 endpoints of receiving a consulting fee and receiving a research payment with various institution-specific and practitioner-specific variables included as covariates: specialty, sex, National Cancer Institute designation, PhD status, and geographic region. The majority of leaders in MO were reported to have received consulting fees or research payments (69.5%) compared with a minority of RO chairs (27.2%). Among those receiving payments, the average (range) consulting fee was $13,413 ($200-$70,423) for MO leaders and $6463 ($837-$16,205) for RO chairs; the average research payment for MO leaders receiving payments was $240,446 ($156-$1,234,762) and $295,089 ($160-$1,219,564) for RO chairs. On multivariable regression when the endpoint was receipt of a research payment, those receiving a consulting fee (odds ratio [OR]: 5.34; 95% confidence interval [CI]: 2.22-13.65) and MO leaders (OR: 5.54; 95% CI: 2.62-12.18) were more likely to receive research payments. Examination of the receipt of consulting fees as the endpoint showed that those receiving a research payment (OR: 5.41; 95% CI: 2.23-13.99) and MO leaders (OR: 3.06; 95% CI: 1.21-8.13) were more likely to receive a consulting fee.

    Full Text Available Abstract Background Malignant breast neoplasms are among the most frequent forms of cancer in the Western world. Conventional treatment of breast cancer may include surgery, hormonal therapy, chemotherapy, radiation and/or immunotherapy, all of which are often accompanied by severe side effects. Complementary and alternative medicine (CAM treatments have been shown to be effective in alleviating those symptoms. Furthermore, with patient survival rates increasing, oncologists, psychologists and other therapists have to become more sensitive to the needs of cancer survivors that go beyond than the mere alleviation of symptoms. Many CAM methods are geared to treat the patient in a holistic manner and thus are also concerned with the patient’s psychological and spiritual needs. Discussion The use of certain CAM methods may become problematic when, as frequently occurs, patients use them indiscriminately and without informing their oncologists. Herbal medicines and dietary supplements, especially, may interfere with primary cancer treatments or have other detrimental effects. Thus, expertise in this highly specialized field of integrative medicine should be available to patients so that they can be advised about the benefits and negative effects of such preparations and practices. Being a beneficial combination of conventional and CAM care, integrative oncology makes possible the holistic approach to cancer care. The concept of integrative oncology for breast cancer is jointly practiced by the Department of Internal and Integrative Medicine, Kliniken Essen-Mitte, academic teaching hospital of the University of Duisburg-Essen, and the Breast Center at Kliniken Essen-Mitte in Germany. This model is introduced here; its scope is reviewed, and its possible implications for the practice of integrative medicine are discussed. Summary Evidence-based integrative care is crucial to the field of oncology in establishing state-of-the-art care for breast

Statistical analyses were performed to examine the relationships between the apprehension levels and various factors. Results: The total PEAS scores exhibited internal consistency and reliability, with a Cronbach α=0.897 and Pearson’s r=0.9030. Of the 201 nurses, 184 provided a valid response (91.5%. Education level was significantly correlated with personal (P<0.01 and professional apprehension levels (P<0.05. Higher apprehension level was found in nurses with less education. Conclusion: The PEAS quantitative survey is useful for evaluating apprehension levels of nurses toward hospice care. Nurses with more education experienced less anxiety when providing care for terminally ill patients. The findings suggested that education programs on hospice care could be strengthened to help nurses cope with negative attitudes toward end-of-life care.

    Sub-specialty training in otorhinolaryngology and head and neck surgery (ORL-HNS) is not standardised across European Union (EU) states and remains diverse. The objective of this study was to assess the current status of sub-specialty training programmes in head and neck surgical oncology within the European Union (EU-15). A postal questionnaire was distributed to 41 representative members of the European Federation of Otorhinolaryngological Societies (EUFOS) in the specialty of ORL-HNS in 15 EU states. The questionnaire included questions regarding the sub-specialty practice, structure, length, access, examination procedures and certification, future developments and also a space for individual comments. Thirty-one respondents (75.6%) from major training centres in 15 different European countries replied. Overall, the data revealed major diversity for all aspects analysed, between and within the different European countries. Only four EU states had formal sub-specialty training in head and neck surgical oncology. This includes Finland, Germany, The Netherlands, and the United Kingdom. In the rest of EU states, the last year of residency programmes is often spent as an introduction to one of the sub-specialties. Sub-specialty training in head and neck surgical oncology within the EU at present is clearly underdeveloped. Issuing a European diploma in ORL-HNS could be an initial step towards assessing the skills acquired during specialist training within the different European countries and formalising specialist training. This would establish a uniform measure for evaluating candidacy for sub-specialty training both across the EU and for USA, Canada or Australia.

    More than a decade has passed since robotic technology was adopted for abdominal surgery, and virtually every gastrointestinal operation has since been shown to be feasible, safe, and reproducible using the robotic approach. Robotic pancreatic surgery had been left behind at the beginning, because they were technically challenging, requiring not only being very familiar with the robotic technology but also having a perfect knowledge of the anatomical variations, very frequent in this area. Nonetheless in the last few years many authors have approached the robot for pancreatic surgery with very promising results in terms of surgical and oncological outcomes. The aim of this article is to review the literature on robotic pancreatic surgery and to define the state of the art use of the robotic approach for pancreatic disease.

    To evaluate the perceptions of the importance and utility of robot assisted surgery in gynecologic oncology. A 39 question web-based survey was sent to members of the Society of Gynecologic Oncologists. The survey response rate was 28%, with 277 surveys completed. Nearly 40% of respondents felt robotic surgical training was required as a part of their career goals, and 73% of respondents have performed a robotic hysterectomy. Among respondents, 39% felt that robotic surgery was as good as laparoscopic surgery but 23% thought robot assisted surgery should be the gold standard for the treatment of endometrial cancer. Robot assisted surgery is gaining widespread acceptance and is perceived to be as good as laparoscopic surgery for the treatment of early stage endometrial and cervical cancers. Among respondents the greatest benefit of robot assisted surgery was its ease of use and perceived improvement in a patient's quality of life. Copyright © 2010 John Wiley & Sons, Ltd.

    Associating liver partition and portal vein ligation for staged hepatectomy(ALPPS) is a novel approach in liver surgery that allows for extensive resection of liver parenchyma by inducing a rapid hypertrophy of the future remnant liver. However,recent reports indicate that not all patients eligible for ALPPS will benefit from this procedure. Therefore,careful patient selection will be necessary to fully exploit possible benefits of ALPPS. Here,we provide a comprehensive overview of the technical evolution of ALPPS with a special emphasis on safety and oncologic efficacy. Furthermore,we review the contemporary literature regarding indication and benefits,but also limitations of ALPPS.

  7. Hepatic Radioembolization as a Bridge to Liver Surgery

    Full Text Available Treatment of oncologic disease has improved significantly in the last decades and in the future a vast majority of cancer types will continue to increase worldwide. As a result many patients are confronted with primary liver cancers or metastatic liver disease. Surgery in liver malignancies has steeply improved and curative resections are applicable in wider settings, leading to a prolonged survival. Simultaneously, radiofrequency ablation (RFA and liver transplantation (LTx have been applied more commonly in oncologic settings with improving results. To minimize adverse events in treatments of liver malignancies, locoregional minimal invasive treatments have made their appearance in this field, in which radioembolization (RE has shown promising results in recent years with few adverse events and high response rates. We discuss several other applications of radioembolization for oncologic patients, other than its use in the palliative setting, whether or not combined with other treatments. This review is focused on the role of RE in acquiring patient eligibility for radical treatments, like surgery, RFA and LTx. Inducing significant tumor reduction can downstage patients for resection or, through attaining stable disease, patients can stay on the LTx waiting list. Hereby, RE could make a difference between curative of palliative intent in oncologic patient management. Prior to surgery, the future remnant liver volume might be inadequate in some patients. In these patients, forming an adequate liver reserve through RE leads to prolonged survival without risking postoperative liver failure and minimizing tumor progression while inducing hypertrophy. In order to optimize results, developments in procedures surrounding RE are equally important. Predicting the remaining liver function after radical treatment and finding the right balance between maximum tumor irradiation and minimizing the chance of inducing radiation-related complications are still

    Full Text Available Background: While limb salvage surgery has long been established as the standard of care for osteosarcoma, large studies from Indian centers are few. Given the diverse socio economic milieu of our patients, it becomes significant to determine the feasibility and outcome of management of osteosarcoma in our population. We analyzed the early outcome of limb salvage surgery with multimodality treatment of osteosarcoma of the extremity/girdle bones at a tertiary North Indian Cancer Centre. Materials and Methods: A total of 51 limb salvage surgeries performed during the months between November 2008 and November 2012 were studied. Neoadjuvant/adjuvant chemotherapy was given by the pediatric/adult medical oncology teams as applicable. The mean followup was 19.45 months (range 2-50 months. The oncological outcome was correlated with age, sex, size of tumor, stage at presentation, site, histological subtype, type of chemotherapy protocol followed and necrosis seen on postoperative examination of resected specimen. The functional outcome of the patients was evaluated using the musculoskeletal tumor society (MSTS scoring system. Results: Out of a total of 37 males and 14 females with an average age of 18.8 years, the 3 year overall survival was 66% and 3 year event free survival was 61.8%. In this group of patients with a short followup, a better oncological outcome was associated with good postoperative tumor necrosis, nonchondroblastic histology and age <14 years. The average MSTS score was highest in patients with proximal or distal femur prosthesis and the lowest in patients undergoing a knee arthrodesis. Conclusion: The present study shows oncological and functional outcomes of limb salvage combined with chemotherapy in Indian patients with osteosarcoma comparable to those in world literature. Larger studies on Indian population with longer followup are recommended.

    This study aimed to describe the contemporary role of the oncology nurse throughout the entire cancer shared decision-making (SDM) process. Study participants consisted of 30 nurses and nurse practitioners who are actively involved in direct care of patients with cancer in the inpatient or outpatient setting. The major themes that emerged from the content analysis are: oncology nurses have various roles at different time points and settings of cancer SDM processes; patient education, advocacy, and treatment side effects management are among the top nursing roles; oncology nurses value their participation in the cancer SDM process; oncology nurses believe they have a voice, but with various degrees of influence in actual treatment decisions; nurses' level of disease knowledge influences the degree of participation in cancer SDM; and the nursing role during cancer SDM can be complicated and requires flexibility.

    Oncology nurses have a higher risk and rate of compassion fatigue (CF) compared to professionals in other specialties. CF exhibits tangible negative outcomes, affecting nurses' health and professional practice.
. Early-career oncology nurses' unique CF experiences lack thorough scientific exploration. This secondary analysis seeks to qualitatively augment this paucity and illuminate targeted interventions.
. Open-ended interviews were conducted with five early-career inpatient oncology nurses. Subsequent transcripts were explored for CF themes secondarily using thematic analysis.
. Themes indicate that early-career oncology nurses enjoy connecting with patients and families, but over-relating, long patient stays, and high patient mortality rates trigger CF. Symptoms include internalizing patients' and families' pains and fears, being haunted by specific patient deaths, feeling emotionally depleted, assuming that all patients will die, and experiencing burnout, physical exhaustion, and hypervigilance protecting loved ones.

    Due to the uncertainty of the course of diagnoses, patients with neuro-oncological malignancies present challenges to the physical therapist. At times, the presentation of impairments and disabilities of these patients with neuro-oncological diagnoses do not necessarily coincide with the involved area of the brain or spinal cord. It is our intention to provide guidance to the physical therapist who will be working with these patients with neuro-oncological diagnoses, in hopes that their encounters will be more productive and meaningful. This article describes a brief overview of common central nervous system malignancies, its medical treatment, as well as possible complications and side effects that would need to be considered in rehabilitating these patients. Special consideration is given to the elderly patients with neuro-oncological diagnoses. Pertinent physical therapy assessments and interventions are discussed.

    Cancer is a major public health problem in Africa. Advances in the treatment of cancers over the last decade are undeniable. Multidisciplinary approach is essential for improved patient's management. Medical oncology is a recently-recognized speciality in Africa Indeed, many African countries do not have doctors or a sufficient number of doctors qualified to practice in this medical specialty. The fight against cancer in Africa involves oncology speciality training and the development of curricula in order to ensure optimum patient management.

    During the 3 centuries reviewed herein, all that was known regarding cancer was limited to Italy, France, Germany, and England. Practically nothing was written about cancer in the rest of the known world, including the newly discovered geographic areas in the Americas, Africa, and Australia. The 7 pioneer physicians considered in this review lived through some of the most turbulent geopolitical, social, and religious upheavals that Europe had experienced during the Renaissance. Despite their diverse social, political, and religious backgrounds and disparate personalities, they were united in their commitment to the advancement of medicine and oncology and to spreading knowledge through printed texts. Collectively, they established the groundwork for modern anatomy, physiology, chemistry, pathology, surgical oncology, and chemotherapy. It perhaps is noteworthy that 5 of the 7 physicians who contributed the most to the advancement of surgery and surgical oncology served in various wars as army surgeons. Considering everything together, the refusal of physicians of this epoch to use the microscope is a historical enigma. Cancer 2017. © 2017 American Cancer Society.

    2010-01-01

    We evaluated the use of a hyaluronic acid-carboxycellulose membrane (HAC) slurry in complex laparoscopies. A gel-like mixture of HAC was prepared and applied in 171 consecutive complex laparoscopies on a gynecologic oncology service. The HAC slurry was used to coat deperitonealized surfaces and surgical pedicals to prevent postoperative adhesions. The technique is described and the outcomes are prospectively evaluated for feasibility and safety. There were no postoperative bowel obstructions, 1 pelvic hematoma in a patient on clopidogrel (Plavix) immediately prior to surgery, 8 postoperative ilea, and 1 bowel perforation. The bowel perforation occurred in a patient with extensive adhesiolysis and intraoperative bowel suturing. This report describes an easy approach to the laparoscopic application of HAC. Caution should be taken if HAC slurry is applied after significant bowel suturing because 1 of 9 patients with extensive adhesiolysis requiring suturing of the sigmoid colon developed sigmoid perforations.

    The care of children with malignant solid tumors in sub-Saharan Africa is compromised by resource deficiencies that range from inadequate healthcare budgets and a paucity of appropriately trained personnel, to scarce laboratory facilities and inconsistent drug supplies. Patients face difficulties accessing healthcare, affording investigational and treatment protocols, and attending follow-up. Children routinely present with advanced local and metastatic disease and many children cannot be offered any effective treatment. Additionally, multiple comorbidities, including malaria, tuberculosis, and HIV when added to acute on chronic malnutrition, compound treatment-related toxicities. Survival rates are poor. Pediatric surgical oncology is not yet regarded as a health care priority by governments struggling to achieve their millennium goals. The patterns of childhood solid malignant tumors in Africa are discussed, and the difficulties encountered in their management are highlighted. Three pediatric surgeons from different regions of Africa reflect on their experiences and review the available literature. The overall incidence of pediatric solid malignant tumor is difficult to estimate in Africa because of lack of vital hospital statistics and national cancer registries in most of countries. The reported incidences vary between 5% and 15.5% of all malignant tumors. Throughout the continent, patterns of malignant disease vary with an obvious increase in the prevalence of Burkitt lymphoma (BL) and Kaposi sarcoma in response-increased prevalence of HIV disease. In northern Africa, the most common malignant tumor is leukemia, followed by brain tumors and nephroblastoma or neuroblastoma. In sub-Saharan countries, BL is the commonest tumor followed by nephroblastoma, non-Hodgkin lymphoma, and rhabdomyosarcoma. The overall 5-years survival varied between 5% (in Côte d'Ivoire before 2001) to 34% in Egypt and up to 70% in South Africa. In many reports, the survival rate of

    Cancer treatment is a major burden for the patient and its family that requires an individualized management by healthcare professionals. Nurses are in charge of coordinating care and are the closest healthcare professionals to patient and family; however, in Spain, there are not standard protocols yet for the management of oncology patients. The Spanish Oncology Nursing Society developed between 2012 and 2014 the SHARE project, with the aim of establishing strategies to improve quality of life and nursing care in oncology patients. It was developed in 3 phases. First, a literature search and review was performed to identify nursing strategies, interventions and tools to improve cancer patients' care. At the second stage, these interventions were agreed within a group of oncology nursing experts; and at the third phase, a different group of experts in oncology care categorized the interventions to identify the ones with highest priority and most feasible to be implemented. As a result, 3 strategic actions were identified to improve nursing care during cancer treatment: To provide a named nurse to carry out the follow up process by attending to the clinic or telephonic consultation, develop therapeutic education with adapted protocols for each tumor type and treatment and ensure specific training for nurses on the management of the cancer patients. Strategic actions proposed in this paper aim to improve cancer patients' healthcare and quality of life through the development of advanced nursing roles based on a higher level of autonomy, situating nurses as care coordinators to assure an holistic care in oncology patients.

    The SEOM Future Plan is aimed at identifying the main challenges, trends and needs of the medical oncology speciality over the next years, including potential oncologist workforce shortages, and proposing recommendations to overcome them. The estimations of the required medical oncologists workforce are based on an updated Medical Oncologist Register in Spain, Medical Oncology Departments activity data, dedication times and projected cancer incidence. Challenges, needs and future recommendations were drawn from an opinion survey and an advisory board. A shortage of 211 FTE medical oncologist specialists has been established. To maintain an optimal ratio of 158 new cases/FTE, medical oncology workforce should reach 1881 FTE by 2035. Main recommendations to face the growing demand and complexity of oncology services include a yearly growth of 2.5% of medical oncologist's workforce until 2035, and development and application of more accurate quality indicators for cancer care and health outcomes measure.

    2016-02-27

    Minimal access surgery has revolutionised colorectal surgery by offering reduced morbidity and mortality over open surgery, while maintaining oncological and functional outcomes with the disadvantage of additional practical challenges. Robotic surgery aids the surgeon in overcoming these challenges. Uptake of robotic assistance has been relatively slow, mainly because of the high initial and ongoing costs of equipment but also because of limited evidence of improved patient outcomes. Advances in robotic colorectal surgery will aim to widen the scope of minimal access surgery to allow larger and more complex surgery through smaller access and natural orifices and also to make the technology more economical, allowing wider dispersal and uptake of robotic technology. Advances in robotic endoscopy will yield self-advancing endoscopes and a widening role for capsule endoscopy including the development of motile and steerable capsules able to deliver localised drug therapy and insufflation as well as being recharged from an extracorporeal power source to allow great longevity. Ultimately robotic technology may advance to the point where many conventional surgical interventions are no longer required. With respect to nanotechnology, surgery may eventually become obsolete.

    Introduction To assess the oncological outcomes of robotic radical prostatectomy in a country where there are no on-going national screening programs for prostate cancer. Material and methods Between November 2009 and November 2014, 220 robotic radical prostatectomies were performed at our Robotic Surgery Center. We already have the complete data for the 2-year follow-up of the first 105 patients, who were therefore included in the study group. Pre-operative (age, prostate-specific antigen, body-mass index, prostate volume, clinical staging, biopsy characteristics), post-operative (surgical technique, surgical margin status, lymph node status, pathological stage, Gleason score) and follow-up parameters (biochemical recurrence) were assessed. Results The global rate of positive surgical margins was 34.3%, with rates of 17.2% in stage pT2 and 55.3% in stage pT3. The most frequent localization for positive surgical margins was at the base and apex of the prostate. The positive surgical margins rate was correlated with the pre-operative prostate-specific antigen, clinical and pathological Gleason score, lymph node status and the number of positive biopsy cores. The rate of biochemical recurrence at the 2-year follow-up was 11.8%. The most important predictors for the biochemical recurrence were the positive surgical margins, pathological staging and Gleason score on the prostatectomy specimen. Conclusions Robotic surgery is validated by the oncological results at medium follow-up (2 years) for localized and locally advanced prostate cancer, even in countries where there is no on-going national screening program.

    Since laparoscopy was first used in cholecystectomy in 1987, it has developed quickly and has been used in most fields of traditional surgery. People have now accepted its advantages like small incision, quick recovery, light pain, beauty and short hospital stays. In early times, there are still controversies about the application of laparoscopy in malignant tumor treatments, especially about the problems of oncology efficacy, incision implantation and operation security. However, these concerns have been fully eliminated by evidences on the basis of evidence-basis medicine. In recent years, new minimally invasive technologies are appearing continually, but they still have challenges and may increase the difficulties of radical dissection and the risks of potential complications, so they are confined to benign or early malignant tumors. The core value of the laparoscopic technique is to ensure the high quality of tumor's radical resection and less complications. On the basis of this, it is allowed to pursue more minimally invasive techniques. Since the development of laparoscopic colorectal surgery is rapid and unceasing, we have reasons to believe that laparoscopic surgery will become gold standard for colorectal surgery in the near future.

    Imaging biomarkers derived from MRI or CT describe functional properties of tumours and normal tissues. They are finding increasing numbers of applications in diagnosis, monitoring of response to treatment and assessment of progression or recurrence. Imaging biomarkers also provide scope for assessment of heterogeneity within and between lesions. A wide variety of functional parameters have been investigated for use as biomarkers in oncology. Some imaging techniques are used routinely in clinical applications while others are currently restricted to clinical trials or preclinical studies. Apparent diffusion coefficient, magnetization transfer ratio and native T{sub 1} relaxation time provide information about structure and organization of tissues. Vascular properties may be described using parameters derived from dynamic contrast-enhanced MRI, dynamic contrast-enhanced CT, transverse relaxation rate (R{sub 2}*), vessel size index and relative blood volume, while magnetic resonance spectroscopy may be used to probe the metabolic profile of tumours. This review describes the mechanisms of contrast underpinning each technique and the technical requirements for robust and reproducible imaging. The current status of each biomarker is described in terms of its validation, qualification and clinical applications, followed by a discussion of the current limitations and future perspectives.

    Experimental oncology research and preclinical drug development both substantially require specific, clinically relevant in vitro and in vivo tumor models. The increasing knowledge about the heterogeneity of cancer requested a substantial restructuring of the test systems for the different stages of development. To be able to cope with the complexity of the disease, larger panels of patient-derived tumor models have to be implemented and extensively characterized. Together with individual genetically engineered tumor models and supported by core functions for expression profiling and data analysis, an integrated discovery process has been generated for predictive and personalized drug development.Improved “humanized” mouse models should help to overcome current limitations given by xenogeneic barrier between humans and mice. Establishment of a functional human immune system and a corresponding human microenvironment in laboratory animals will strongly support further research.Drug discovery, systems biology, and translational research are moving closer together to address all the new hallmarks of cancer, increase the success rate of drug development, and increase the predictive value of preclinical models.

    This article explores the emergence of a 'regime of hope' in the context of oncology care, practice and research. More specifically, my focus is the emergence, since the 1970s or so, of hope scales and indexes used to metricise the emotional states of cancer patients. These usually take the form of psychometric tests designed and deployed in order to subject affective life to calculative and rational scrutiny. This article locates this within the tensions of a 'turn' towards the emotions in critical social science literature. Scholarship has, for instance, been anxious not to deny the embodied reality of affectivity and the emotions. But it has been equally important to recognise the extent to which emotions are discursively ordered and structured as objects and effects of power. This article charts the emergence of hope scales historically alongside wider historical forces in the metrification of life and health and more specifically the emotions. It locates hope scales in a post-war climate of individual resilience and perseverant enterprise and the significance of hope as a naturalised vitalistic attribute of biopolitical life.

    The history of the term Lean is relatively recent and originates from the Toyota Production System (TPS). The term "Lean" means "thin", which refers to a mental process, operational, productive, no-frills, quick but not hasty, consequential to the previous event. The Lean process flows seamlessly into the result, eliminates unnecessary complications to the effect, prevents unnecessary equipment processes. The idea is to 'do more with less', like using the (few) available resources in the most productive way possible, through the elimination of all types of waste that inevitably accompanies every stage of a production process. Lean management is primarily a management philosophy, a system of values and behaviors that goes beyond the mere application of the instrument and that, once internalized, will form the nucleus of the corporate culture. "Lean Oncology" is a term coined to identify a methodology of care and treatment to cancer patients, consisting on process simplification, streamlining of the organizational and routes of drug treatment, detection and elimination of waste. Its main objective is the centrality of the patient.

    Our objective was to determine whether and how quantitative information about drug benefits and risks is presented to consumers and healthcare professionals on cancer-related prescription drug websites. We analyzed the content of 65 active cancer-related prescription drug websites. We assessed the inclusion and presentation of quantitative information for two audiences (consumers and healthcare professionals) and two types of information (drug benefits and risks). Websites were equally likely to present quantitative information for benefits (96.9 %) and risks (95.4 %). However, the amount of the information differed significantly: Both consumer-directed and healthcare-professional-directed webpages were more likely to have quantitative information for every benefit (consumer 38.5 %; healthcare professional 86.1 %) compared with every risk (consumer 3.1 %; healthcare professional 6.2 %). The numeric and graphic presentations also differed by audience and information type. Consumers have access to quantitative information about oncology drugs and, in particular, about the benefits of these drugs. Research has shown that using quantitative information to communicate treatment benefits and risks can increase patients' and physicians' understanding and can aid in treatment decision-making, although some numeric and graphic formats are more useful than others.

    Since its introduction in the early nineties as a promising functional imaging technique in the management of neoplastic disorders, FDG-PET, and subsequently FDG-PET/CT, has become a cornerstone in several oncologic procedures such as tumor staging and restaging, treatment efficacy assessment during or after treatment end and radiotherapy planning. Moreover, the continuous technological progress of image generation and the introduction of sophisticated software to use PET scan as a biomarker paved the way to calculate new prognostic markers such as the metabolic tumor volume (MTV) and the total amount of tumor glycolysis (TLG). FDG-PET/CT proved more sensitive than contrast-enhanced CT scan in staging of several type of lymphoma or in detecting widespread tumor dissemination in several solid cancers, such as breast, lung, colon, ovary and head and neck carcinoma. As a consequence the stage of patients was upgraded, with a change of treatment in 10%–15% of them. One of the most evident advantages of FDG-PET was its ability to detect, very early during treatment, significant changes in glucose metabolism or even complete shutoff of the neoplastic cell metabolism as a surrogate of tumor chemosensitivity assessment. This could enable clinicians to detect much earlier the effectiveness of a given antineoplastic treatment, as compared to the traditional radiological detection of tumor shrinkage, which usually takes time and occurs much later.

    Given the dramatic demographic shift observed in developed countries, the medical community, especially oncologists, geriatricians, and primary care providers, are confronted with the expanding challenge of the management of elderly people with cancer. Ageing is associated with the accumulation of multiple and various medical and social problems. With a prevalence comparable to that of other chronic conditions in this age group, such as diabetes or dementia, cancer holds a prominent place among diseases of the elderly. The care of elderly cancer patients is fundamentally interdisciplinary. Communication and collaboration between geriatricians/primary care providers and oncologists represent key features of effective care in geriatric oncology. The combination of the disease-oriented approach of oncologists and the patient-oriented approach of geriatricians is the most powerful way to better serve this specific population. The medical approach of elderly cancer patients should ideally be under the lead of geriatricians or primary care providers sensitive to geriatric issues. Oncologists should manage the biologic consequences of the interplay between cancer and ageing. Close collaboration between clinicians will help promote active dedicated clinical research and the development of guidelines on the management of elderly people with cancer.

    Recent advances in the development of functional materials offer new tools to dissect human health and disease mechanisms. The use of tunable surfaces is especially appealing as substrates can be tailored to fit applications involving specific cell types or tissues. Here we use tunable materials to facilitate the three-dimensional (3D) analysis of BRCA1 gene regulatory complexes derived from human cancer cells. We employed a recently developed microchip platform to isolate BRCA1 protein assemblies natively formed in breast cancer cells with and without BRCA1 mutations. The captured assemblies proved amenable to cryo-electron microscopy (EM) imaging and downstream computational analysis. Resulting 3D structures reveal the manner in which wild-type BRCA1 engages the RNA polymerase II (RNAP II) core complex that contained K63-linked ubiquitin moieties—a putative signal for DNA repair. Importantly, we also determined that molecular assemblies harboring the BRCA15382insC mutation exhibited altered protein interactions and ubiquitination patterns compared to wild-type complexes. Overall, our analyses proved optimal for developing new structural oncology applications involving patient-derived cancer cells, while expanding our knowledge of BRCA1’s role in gene regulatory events.

    2012-01-01

    Professional patient boundaries are an issue that is relevant across all realms of nursing practice. By nature, nurses are caring individuals. Therapeutic relationships are integral to the care of patients. When caring for patients on a daily basis for extended periods of time, it can be difficult for nurses to know when their care goes beyond professional boundaries. Providing care to patients in a pediatric oncology situation substantially increases this ethical dilemma. Length of stay, degree of crisis, embedded relationships, and emotional turmoil, along with the nurturing connection between adult and child, are among the reasons that boundaries are often blurred within the context of this sensitive patient population. This article explores the differences between nursing care, boundary crossings, and boundary violations. Strategies to evaluate nursing actions for appropriateness, along with reflection and development of individual boundaries, are offered. The information presented is relevant not only to nursing care of pediatric patients who are facing chronic or life-threatening conditions but also to each nurse-client relationship established in nursing practice.

    2017-01-01

    Patients with brain tumors and systemic malignancies are subject to diverse neurologic complications that require urgent evaluation and treatment. These neurologic conditions are commonly due to the tumor's direct effects on the nervous system, such as cerebral edema, increased intracranial pressure, seizures, spinal cord compression, and leptomeningeal metastases. In addition, neurologic complications can develop as a result of thrombocytopenia, coagulopathy, hyperviscosity syndromes, infection, immune-related disorders, and adverse effects of treatment. Patients may present with typical disease syndromes. However, it is not uncommon for patients to have more subtle, nonlocalizing manifestations, such as alteration of mental status, that could be attributed to other systemic, nonneurologic complications. Furthermore, neurologic complications are at times the initial manifestations of an undiagnosed malignancy. Therefore a high index of suspicion is essential for rapid assessment and management. Timely intervention may prolong survival and improve quality of life. In this chapter, we will discuss the common neuro-oncologic emergencies, including epidemiology, pathophysiology, clinical presentation, diagnosis, and treatment. © 2017 Elsevier B.V.

    By now therapy decision taken by a multi-disciplinary oncology team in cancer care has become a routine method in worldwide. However, multi-disciplinary oncology team has to face more and more difficulties in keeping abreast with the fast development in oncology science, increasing expectations, and financial considerations. Naturally the not properly controlled decision mechanisms, the permanent lack of time and shortage of professionals are also hindering factors. Perhaps it would be a way out if the staff meetings and discussions of physicians in the oncology departments were transformed and provided with administrative, legal and decision credentials corresponding to those of multi-disciplinary oncology team. The new form of the oncotherapy oncoteam might be able to decide the optimal and particular treatment after previous consultation with the patient. The oncotherapy oncoteam is also suitable to carry out training and tasks of a cancer centre and by diminishing the psychological burden of the doctors it contributes to an improved patient care. This study presents the two-level multi-disciplinary and oncotherapy oncology team system at the University of Pécs including the detailed analysis of the considerations above.

    Arterial pseudoaneurysm is an uncommon lethal complication following hepato-pancreato-biliary surgery. Aim of this study is to present and discuss the experience of a high volume oncological center. Since 2007 all major surgeries performed at Sanchinarro Oncological Center have been included in a prospective database looking for postoperative arterial pseudonaurysm. Until June 2014, among 559 hepato-pancreato-biliary procedures, a total of 14 arterial pseudoaneurysms have been identified (2.5%). Sentinel bleeding was in 57% of cases. Failed arterial embolization occurred in 2 cases. Overall mortality rate was 28.5%. We also identified 3 asymptomatic pseudoaneurysms, one of them managed without embolization, developing a sudden bleeding and died after surgery. According to our experience, pseudoaneurysm incidence is higher than reported in current literature and it can be successfully managed through arterial embolization. Furthermore, we found 3 asymptomatic pseudoaneurysms, whose management is still controversial.

    Full Text Available An increasing proportion of patients requiring treatment for malignancy are elderly, which has created new challenges for oncologic surgeons. Aging is associated with an increasing prevalence of frailty and comorbidities that may affect the outcome of surgical procedures. By decreasing complications and shortening length of hospital stay without affecting oncologic safety, surgery performed using the robot, rather than traditional laparotomy, improves the chances of a better outcome in our growing elderly populations. In addition to age, surgeons should take into account factors, such as frailty and comorbidities that correlate with outcome.

    Full Text Available Background: Minimally invasive single-site (MISS surgery has recently been applied to colorectal surgery. We aimed to assess the current state of the art and the adequacy of preliminary oncological results. Methods: We performed a systematic review of the literature using Pubmed, Medline, SCOPUS and Web of Science databases. Keywords used were "Single Port" or "Single-Incision" or "LaparoEndoscopic Single Site" or "SILS™" and "Colon" or "Colorectal" and "Surgery". Results: Twenty-nine articles on colorectal MISS surgery have been published from July 2008 to July 2010, presenting data on 149 patients. One study reported analgesic requirement. The final incision length ranged from 2.5 to 8 cm. Only two studies reported fascial incision length. There were two port site hernias in a series of 13 patients (15.38%. Two "fully laparoscopic" MISS procedures with preparation and achievement of the anastomosis completely intracorporeally are reported. Future site of ileostomy was used as the sole access for the procedures in three studies. Lymph node harvesting, resection margins and length of specimen were sufficient in oncological cases. Conclusions: MISS colorectal surgery is a challenging procedure that seems to be safe and feasible, but the existing clinical evidence is limited. In selected cases, and especially when an ileostomy is planned, colorectal surgery may be an ideal indication for MISS surgery leading to a no-scar surgery. Despite preliminary oncological results showing the feasibility of MISS surgery, we want to stress the need to standardize the technique and carefully evaluate its application in oncosurgery under ethical committee control.

    Full Text Available Purpose To report the outcomes of patients with pathologic T4 UTUC and investigate the potential impact of peri-operative chemotherapy combined with radical nephroureterectomy (RNU and regional lymph node dissection (LND on oncologic outcomes. Materials and Methods Patients with pathologic T4 UTUC were identified from the cohort of 1464 patients treated with RNU at 13 academic centers between 1987 and 2007. Oncologic outcomes were stratified according to utilization of perioperative systemic chemotherapy and regional LND as an adjunct to RNU. Results The study included 69 patients, 42 males (61% with median age 73 (range 43-98. Median follow-up was 17 months (range: 6-88. Lymphovascular invasion was found in 47 (68% and regional lymph node metastases were found in 31 (45%. Peri-operative chemotherapy was utilized in 29 (42% patients. Patients treated with peri-operative chemotherapy and RNU with LND demonstrated superior oncologic outcomes compared to those not treated by chemotherapy and/or LND during RNU (3Y-DFS: 35% vs. 10%; P = 0.02 and 3Y-CSS: 28% vs. 14%; P = 0.08. In multivariate Cox regression analysis, administration of peri-operative chemotherapy and utilization of LND during RNU was associated with lower probability of recurrence (HR: 0.4, P = 0.01, and cancer specific mortality (HR: 0.5, P = 0.06. Conclusions Pathological T4 UTUC is associated with poor prognosis. Peri-operative chemotherapy combined with aggressive surgery, including lymph node dissection, may improve oncological outcomes. Our findings support the use of aggressive multimodal treatment in patients with advanced UTUC.

    Laparoscopic surgery is now an integral technique in the practice of urology, particularly in the management of certain urologic malignancies. Advanced laparoscopy training in urology is primarily reserved for those pursuing fellowship training and is offered both by traditional endourology fellowships and increasingly in urologic oncology fellowships. The purpose of our study was to evaluate and compare current laparoscopy training at the fellowship level. A 17-item questionnaire was developed with support from both the Endourological Society (EUS) and Society of Urologic Oncology (SUO). Surveys were sent to program directors of fellowships recognized by the EUS and SUO. Directors were surveyed on the laparoscopic case volume, degree of oncology training, and career choice of their graduates. Data were analyzed with Wilcoxon rank-sum and Student t tests. Our survey had an overall response rate of 60%. Fellows performed more than 100 laparoscopies during their training period in 57% of EUS and 25% of SUO fellowship programs. Similar trends are demonstrated when analyzing robotic procedures, with 73% of EUS fellows performing more than 50 procedures compared with 43% of SUO fellows. The majority (59%) of EUS programs provide oncologic training. Between 44% and 100% of graduates from EUS and SUO fellowships obtain academic positions. The majority of SUO directors (63%) believe that fellowship training in laparoscopy should be provided in fellowships governed solely by the SUO, while 41% of EUS directors believe this training should be governed solely by the EUS. Endourology fellowships currently provide a greater exposure to laparoscopy and robotics than SUO fellowships. The percentage of fellows seeking academic positions is similar for EUS and SUO fellowship programs and has remained stable for several years. Directors of fellowship programs that offer advanced laparoscopic training have divergent views as to which administrative body should govern its future.

    Surgery can only maintain its role in a highly competitive environment if results are continuously improved, accompanied by further reduction of the interventional trauma for patients and with justifiable costs. Significant impulse to achieve this goal was expected from minimally invasive surgery and, in particular, robotic surgery; however, a real breakthrough has not yet been achieved. Accordingly, the new strategic approach of cognitive surgery is required to optimize the provision of surgical treatment. A full scale integration of all modules utilized in the operating room (OR) into a comprehensive network and the development of systems with technical cognition are needed to upgrade the current technical environment passively controlled by the surgeon into an active collaborative support system (surgery 4.0). Only then can the true potential of minimally invasive surgery and robotic surgery be exploited.

    Th2 immunity and allergic immune surveillance play critical roles in host responses to pathogens, parasites and allergens. Numerous studies have reported significant links between Th2 responses and cancer, including insights into the functions of IgE antibodies and associated effector cells in both antitumour immune surveillance and therapy. The interdisciplinary field of AllergoOncology was given Task Force status by the European Academy of Allergy and Clinical Immunology in 2014. Affiliated expert groups focus on the interface between allergic responses and cancer, applied to immune surveillance, immunomodulation and the functions of IgE-mediated immune responses against cancer, to derive novel insights into more effective treatments. Coincident with rapid expansion in clinical application of cancer immunotherapies, here we review the current state-of-the-art and future translational opportunities, as well as challenges in this relatively new field. Recent developments include improved understanding of Th2 antibodies, intratumoral innate allergy effector cells and mediators, IgE-mediated tumour antigen cross-presentation by dendritic cells, as well as immunotherapeutic strategies such as vaccines and recombinant antibodies, and finally, the management of allergy in daily clinical oncology. Shedding light on the crosstalk between allergic response and cancer is paving the way for new avenues of treatment.

    Standardization of care can reduce the risk of errors, increase efficiency, and provide a framework for best practice. In 2008, the American Society of Clinical Oncology (ASCO) and the Oncology Nursing Society (ONS) invited a broad range of stakeholders to create a set of standards for the administration of chemotherapy to adult patients in the outpatient setting. At the close of a full-day structured workshop, 64 draft standards were proposed. After a formal process of electronic voting and conference calls, 29 draft standards were eliminated, resulting in a final list of 35 draft measures. The proposed set of standards was posted for 6 weeks of open public comment. Three hundred twenty-two comments were reviewed by the Steering Group and used as the basis for final editing to a final set of standards. The final list includes 31 standards encompassing seven domains, which include the following: review of clinical information and selection of a treatment regimen; treatment planning and informed consent; ordering of treatment; drug preparation; assessment of treatment compliance; administration and monitoring; assessment of response and toxicity monitoring. Adherence to ASCO and ONS standards for safe chemotherapy administration should be a goal of all providers of adult cancer care.

    The offer of "integrative oncology" is one option for clinics to provide safe and evidence-based complementary medicine treatments to cancer patients. As known from merger theories, corporate culture and integration models have a strong influence on the success of such integration. To identify relevant corporate culture aspects that might influence the success in two highly visible integrative oncology clinics, we interviewed physicians, nurses, practitioners, and managers. All interviews (11 in a German breast cancer clinic and 9 in an integrative medicine cancer service in the USA) were audio-recorded, transcribed and analyzed with content analysis. According to the theoretical framework of mergers, each clinic selected a different integration type ("best of both worlds" and "linking"). Nonetheless, each developed a similar corporate culture that has a strong focus on research and safe and evidence-based treatments, and fosters a holistic and patient-centered approach. Structured communication within the team and with other departments had high relevance. Research was highlighted as a way to open doors and to facilitate a more general acceptance within the hospital. Conventional physicians felt unburdened by the provision of integrative medicine service but also saw problems in the time required for scheduled treatments, which often resulted in long waiting lists.

    This article describes the results of a simulation analysis of a payment model for specialty oncology services that is being developed for possible testing by the Center for Medicare and Medicaid Innovation at the Centers for Medicare & Medicaid Services (CMS). CMS asked MITRE and RAND to conduct simulation analyses to preview some of the possible impacts of the payment model and to inform design decisions related to the model. The simulation analysis used an episode-level dataset based on Medicare fee-for-service (FFS) claims for historical oncology episodes provided to Medicare FFS beneficiaries in 2010. Under the proposed model, participating practices would continue to receive FFS payments, would also receive per-beneficiary per-month care management payments for episodes lasting up to six months, and would be eligible for performance-based payments based on per-episode spending for attributed episodes relative to a per-episode spending target. The simulation offers several insights into the proposed payment model for oncology: (1) The care management payments used in the simulation analysis-$960 total per six-month episode-represent only 4 percent of projected average total spending per episode (around $27,000 in 2016), but they are large relative to the FFS revenues of participating oncology practices, which are projected to be around $2,000 per oncology episode. By themselves, the care management payments would increase physician practices' Medicare revenues by roughly 50 percent on average. This represents a substantial new outlay for the Medicare program and a substantial new source of revenues for oncology practices. (2) For the Medicare program to break even, participating oncology practices would have to reduce utilization and intensity by roughly 4 percent. (3) The break-even point can be reduced if the care management payments are reduced or if the performance-based payments are reduced.

  14. Stress Levels of Nurses in Oncology Outpatient Units.

    Oncology nursing is often a source of substantial stress for nurses. Many nurses, particularly novice nurses, have inadequate preparation to care for patients at the end of life and their families. Unless nurses prevent or manage work-related stress by using effective coping strategies, oncology nursing staff will continue to suffer from burnout and compassion fatigue. The purpose of this article is to identify stress levels and stressful factors of nurses working in oncology outpatient units and to explore coping behaviors for work-related stress of oncology staff nurses in outpatient units. A descriptive, cross-sectional design was used to identify stress levels and stressful factors for outpatient oncology nurses, investigate differences in stress levels among nurses' demographic characteristics, and explore coping behaviors of the nurses. Study participants (N = 40) included RNs and licensed practical nurses who completed the Nursing Stress Scale, three open-ended questions, and a demographic questionnaire. The highest sources of stress were workload and patient death and dying. Demographic variables of age and work experience in nursing showed a significant positive relationship to work-related stress scores. The three most frequently used coping behaviors were verbalizing, exercising or relaxing, and taking time for self. Continuing education programs on stress management are highly recommended. Outpatient oncology nurses should be nurtured and supported through tailored interventions at multiple levels to help them find effective coping strategies and develop self-care competencies. Although younger and less experienced nurses had lower mean stress scores than older and more experienced nurses, the continuing education programs and tailored interventions would be helpful for all oncology nursing staff.

    Full Text Available Hubertus Feussner,1 Valentin Becker,2 Margit Bauer,1 Michael Kranzfelder,1 Rebekka Schirren,1 Tim Lüth,3 Alexander Meining,2 Dirk Wilhelm1 1Department of Surgery, 22nd Medical Department, 3Institute of Microtechnology and Medical Device Technology, Klinikum rechts der Isar, Technische Universität München, Germany Abstract: Flexible endoscopy is increasingly developing into a therapeutic instead of a purely diagnostic discipline. Improved visualization makes early lesions easily detectable and allows us to decide ad hoc on the required treatment. Deep enteroscopy allows the exploration of even the small bowel – for long a "white spot" for gastrointestinal endoscopy – and to perform direct treatment. Endoscopic submucosal dissection is a considerable step forward in oncologically correct endoscopic treatment of (early malignant lesions. Though still technically challenging, it is increasingly facilitated by new manipulation techniques and tools that are being steadily optimized. Closure of wall defects and hemostasis could be improved significantly. Even the anatomy beyond the gastrointestinal wall is being explored by the therapeutic use of endoluminal ultrasound. Endosonographic-guided surgery is not only a suitable fallback solution if conventional endoscopic retrograde cholangiopancreatography fails, but even makes necrosectomy procedures, abscess drainage, and neurolysis feasible for the endoscopist. Newly developed endoscopic approaches aim at formerly distinctive surgical domains like gastroesophageal reflux disease, appendicitis, and cholecystitis. Combined endoscopic/laparoscopic interventional techniques could become the harbingers of natural orifice transluminal endoscopic surgery, whereas pure natural orifice transluminal endoscopic surgery is currently still in its beginnings.

    The presence of diplopia is an undesirable result following strabismus surgery. There are a variety of scenarios where diplopia exists prior to strabismus surgery, and, after surgery, has either been alleviated or decreased to a magnitude amenable to prism correction. In other cases, the patient does not experience diplopia prior to the strabismus surgery, but there exists a definite risk of diplopia after the surgery. In the current review, I examine the literature to help determine the incidence of diplopia after strabismus surgery.

  11. Resecting diffuse low-grade gliomas to the boundaries of brain functions: a new concept in surgical neuro-oncology.

    Science.gov (United States)

    Duffau, H

    2015-12-01

    The traditional dilemma making surgery for diffuse low-grade gliomas (DLGGs) challenging is underlain by the need to optimize tumor resection in order to significantly increase survival versus the risk of permanent neurological morbidity. Development of neuroimaging led neurosurgeons to achieve tumorectomy according to the oncological limits provided by preoperative or intraoperative structural and metabolic imaging. However, this principle is not coherent, neither with the infiltrative nature of DLGGs nor with the limited resolution of current neuroimaging. Indeed, despite technical advances, MRI still underestimates the actual spatial extent of gliomas, since tumoral cells are present several millimeters to centimeters beyond the area of signal abnormalities. Furthermore, cortical and subcortical structures may be still crucial for brain functions despite their invasion by this diffuse tumoral disease. Finally, the lack of reliability of functional MRI has also been demonstrated. Therefore, to talk about "maximal safe resection" based upon neuroimaging is a non-sense, because oncological MRI does not show the tumor and functional MRI does not show critical neural pathways. This review proposes an original concept in neuro-oncological surgery, i.e. to resect DLGG to the boundaries of brain functions, thanks to intraoperative electrical mapping performed in awake patients. This paradigmatic shift from image-guided resection to functional mapping-guided resection, based upon an accurate study of brain connectomics and neuroplasticity in each patient throughout tumor removal has permitted to solve the classical dilemma, by increasing both survival and quality of life in DLGG patients. With this in mind, brain surgeons should also be neuroscientists.

    Oxidative stress is thought to be an important factor in the onset, progression and recurrence of cancer. In order to investigate how it is influenced by physical activity, we measured oxidative stress and antioxidative capacity (aoC) in 12 women with breast cancer and 6 men with prostate cancer, before and after long hiking trips. Before the hike, the men had a ROS-concentration of 1.8±0.6 mM H2O2 and an aoC of 0.7±0.6 mM Trolox-equivalent (Tro), while the women had a ROS-concentration of 3.1±0.7 mM H2O2 and an aoC of 1.2±0.2 mM Tro. After the hike, women showed no significant change in ROS and a significant increase in aoC (1.3±0.2 mM Tro), while the ROS concentration in men increased significantly (2.1±0.3 mM H2O2) and their aoC decreased (0.25±0.1 mM Tro). After a regenerative phase, the ROS concentration of the men decreased to 1.7±0.4 mM H2O2 and their aoC recovered significantly (1.2±0.4 mM Tro), while the women presented no significant change in the concentration of H2O2 but showed an ulterior increase in antioxidant capacity (2.05±0.43 mM Tro). From this data we conclude that physical training programs as for example long distance hiking trips can improve the aoC in the blood of oncological patients. © Georg Thieme Verlag KG Stuttgart · New York.

  13. Informal patient payments in oncology practice

    Directory of Open Access Journals (Sweden)

    Fomenko, Tetiana

    2012-07-01

    Full Text Available BACKGROUND: In Europe, new cases of cancer are diagnosed in 4 million people yearly, of whom 837 000 die. In Ukraine of 160 000 new cases almost 100 000 die. With proper treatment, one third of cancer cases is curable, but informal payments (IPP in health care limit access to treatment. We aimed to explore the experience of people treated for cancer to identify obstacles in obtaining health care and the expert opinion about health care for cancer patients in Ukraine.METHODS: The study is exploratory. Semi-structured in-depth interviews were conducted with 15 convenience sample patients or their relatives as well as with three experts between October 2011 – April 2012. RESULTS. Solicitation or receipt of IPP depends on the organizational culture. Respondents do not mind about IPP, but want this to be their own decision. IPP are often considered a “thank” to the medical staff for the service. The significant percentage of expenditures while in treatment for patients is due to purchases of medicines at their own expense. The problem of a long process of diagnostics and incomplete information by the medical staff about the stage of cancer and possible prognoses are essential for the respondents. According to experts not sufficient number of specialists and equipment for proper diagnosis and treatment is another problem. The attitude of medical staff to the patient with cancer largely depends on the personal features of the staff.CONCLUSIONS: Significant problems perceived by cancer patients are related to purchase of medicines at their own expense, structural and organizational features of hospitals, where they are staying for the treatment. Informal payments largely depend on the personal qualities of medical staff. The government must ensure fairness and equal access in getting care in oncology practice because it mainly affects the health of the nation.

    Full Text Available Abstract Mitochondria are sub-cellular organelles that produce adenosine triphosphate (ATP through oxidative phosphorylation (OXPHOS. As suggested over 70 years ago by Otto Warburg and recently confirmed with molecular techniques, alterations in respiratory activity and in mitochondrial DNA (mtDNA appear to be common features of malignant cells. Somatic mtDNA mutations have been reported in many types of cancer cells, and some reports document the prevalence of inherited mitochondrial DNA polymorphisms in cancer patients. Nevertheless, a careful reanalysis of methodological criteria and methodology applied in those reports has shown that numerous papers can't be used as relevant sources of data for systematic review, meta-analysis, or finally for establishment of clinically applicable markers. In this review technical and conceptual errors commonly occurring in the literature are summarized. In the first place we discuss, why many of the published papers cannot be used as a valid and clinically useful sources of evidence in the biomedical and healthcare contexts. The reasons for introduction of noise in data and in consequence - bias for the interpretation of the role of mitochondrial DNA in the complex process of tumorigenesis are listed. In the second part of the text practical aspects of mtDNA research and requirements necessary to fulfill in order to use mtDNA analysis in clinics are shown. Stringent methodological criteria of a case-controlled experiment in molecular medicine are indicated. In the third part we suggest, what lessons can be learned for the future and propose guidelines for mtDNA analysis in oncology. Finally we conclude that, although several conceptual and methodological difficulties hinder the research on mitochondrial patho-physiology in cancer cells, this area of molecular medicine should be considered of high importance for future clinical practice.

    Compared to laparotomic surgery, laparoscopically assisted radical vaginal hysterectomy (LARVH) offers decreased blood loss during surgery and faster convalescence of the patient postoperatively, while at the same time delivering similar oncologic results. However, there is no data on outcome and toxicity of LARVH followed by (chemo)radiation. A total of 55 patients (range 28-78 years) with cervical cancer on FIGO stages IB1-IIIA (Tables 1 and 2) with risk factors were submitted to either external beam radiotherapy alone [EBRT, n = 8 (14%), including paraaortic irradiation, n = 4 (2.2%); EBRT and brachytherapy (BT), n = 33 (60%); BT alone, n = 14 (25.5%)] or chemoradiation after LARVH. At a median follow-up of 4.4 years, the 5-year disease-free survival (DFS) was 81.8% with 84.5% overall survival (OS). Acute grade 3 side effects were seen in 4 patients. These were mainly gastrointestinal (GI) and genitourinary (GU) symptoms. Grade 4 side effects were not observed. With similar oncologic outcome data and mostly mild side effects, LARVH followed by (chemo)radiation is a valid alternative in the treatment of cervical cancer patients. (orig.)

    2010-04-01

    The major impediment to the expansion of oncology services is a shortage of personnel. To develop a distance learning course for radiation oncology trainees. Under the sponsorship of the Asia Pacific Regional Cooperative Agreement administered by the International Atomic Energy Agency (IAEA), a CD ROM-based Applied Sciences of Oncology (ASOC) distance learning course of 71 modules was created. The course covers communications, critical appraisal, functional anatomy, molecular biology, pathology. The materials include interactive text and illustrations that require students to answer questions before they can progress. The course aims to supplement existing oncology curricula and does not provide a qualification. It aims to assist students in acquiring their own profession's qualification. The course was piloted in seven countries in Asia, Africa and Latin America during 2004. After feedback from the pilot course, a further nine modules were added to cover imaging physics (three modules), informed consent, burnout and coping with death and dying, Economic analysis and cancer care, Nutrition, cachexia and fatigue, radiation-induced second cancers and mathematical tools and background for radiation oncology. The course was widely distributed and can be downloaded from http://www.iaea.org/Publications/Training/Aso/register.html. ASOC has been downloaded over 1100 times in the first year after it was posted. There is a huge demand for educational materials but the interactive approach is labour-intensive and expensive to compile. The course must be maintained to remain relevant.

    Cancer is the second leading cause of death in the USA, but there is minimal data on how oncology is taught to medical students. The purpose of this study is to characterize oncology education at US medical schools. An electronic survey was sent between December 2014 and February 2015 to a convenience sample of medical students who either attended the American Society for Radiation Oncology annual meeting or serve as delegates to the American Association of Medical Colleges. Information on various aspects of oncology instruction at participants' medical schools was collected. Seventy-six responses from students in 28 states were received. Among the six most common causes of death in the USA, cancer reportedly received the fourth most curricular time. During the first, second, and third years of medical school, participants most commonly reported 6-10, 16-20, and 6-10 h of oncology teaching, respectively. Participants were less confident in their understanding of cancer treatment than workup/diagnosis or basic science/natural history of cancer (p medical oncologists reportedly performed the majority of teaching, whereas during the clinical clerkships, medical and surgical oncologists reportedly performed the majority of teaching. Radiation oncologists were significantly less involved during both periods (p medical schools, suggesting a need for reform.

    In 2009, the NCI launched the Physical Sciences - Oncology Centers (PS-OC) initiative with 12 Centers (U54) funded through 2014. The current phase of the Program includes U54 funded Centers with the added feature of soliciting new Physical Science - Oncology Projects (PS-OP) U01 grant applications through 2017; see NCI PAR-15-021. The PS-OPs, individually and along with other PS-OPs and the Physical Sciences-Oncology Centers (PS-OCs), comprise the Physical Sciences-Oncology Network (PS-ON). The foundation of the Physical Sciences-Oncology initiative is a high-risk, high-reward program that promotes a `physical sciences perspective' of cancer and fosters the convergence of physical science and cancer research by forming transdisciplinary teams of physical scientists (e.g., physicists, mathematicians, chemists, engineers, computer scientists) and cancer researchers (e.g., cancer biologists, oncologists, pathologists) who work closely together to advance our understanding of cancer. The collaborative PS-ON structure catalyzes transformative science through increased exchange of people, ideas, and approaches. PS-ON resources are leveraged to fund Trans-Network pilot projects to enable synergy and cross-testing of experimental and/or theoretical concepts. This session will include a brief PS-ON overview followed by a strategic discussion with the APS community to exchange perspectives on the progression of trans-disciplinary physical sciences in cancer research.

  1. Nutrition in oncology: the case of micronutrients (review).

    Ströhle, Alexander; Zänker, Kurt; Hahn, Andreas

    2010-10-01

    In the course of cancer disease, many oncological patients develop tumor-associated malnutrition characterized by an insufficient supply of macro- and micronutrients. The inadequate nutritional status and the cancer anorexia-cachexia syndrome related to it are clinically relevant, as the response to antineoplastic measures, such as radiation and chemotherapy, is diminished, their side effects aggravated and the patient's quality of life and prognosis negatively affected. Therefore, the supportive nutrition care of oncological patients is of central importance. In this context, vitamins, minerals and long-chain omega -3 fatty acids are becoming more and more relevant in oncology although the benefit of such supplements is discussed controversially. Starting from a description of the etiopathogenesis and the pathophysiological consequences of cancer-associated malnutrition, the present study provides an overview of the importance of micronutrients for oncological patients. In the case of reduced food intake and/or inappropriate food choice the use of a multi-vitamin-multimineral supplement administered in physiological doses, i.e. nutrient quantities approximately corresponding to the recommended daily allowances, can be generally recommended. However, to enhance postoperative wound healing, it seems that cancer patients require higher amounts of micronutrients than healthy individuals. Because vitamin D deficiency is highly prevalent in oncological patients, improvement of vitamin D status is of special interest.

  4. [Advantages and disadvantages of minimally invasive surgery in colorectal cancer surgery].

    Zheng, Minhua; Ma, Junjun

    2017-06-25

    Since the emergence of minimally invasive technology twenty years ago, as a surgical concept and surgical technique for colorectal cancer surgery, its obvious advantages have been recognized. Laparoscopic technology, as one of the most important technology platform, has got a lot of evidence-based support for the oncological safety and effectiveness in colorectal cancer surgery Laparoscopic technique has advantages in terms of identification of anatomic plane and autonomic nerve, protection of pelvic structure, and fine dissection of vessels. But because of the limitation of laparoscopic technology there are still some deficiencies and shortcomings, including lack of touch and lack of stereo vision problems, in addition to the low rectal cancer, especially male, obese, narrow pelvis, larger tumors, it is difficult to get better view and manipulating triangle in laparoscopy. However, the emergence of a series of new minimally invasive technology platform is to make up for the defects and deficiencies. The robotic surgical system possesses advantages, such as stereo vision, higher magnification, manipulator wrist with high freedom degree, filtering of tremor and higher stability, but still has disadvantages, such as lack of haptic feedback, longer operation time, high operation cost and expensive price. 3D system of laparoscopic surgery has similar visual experience and feelings as robotic surgery in the 3D view, the same operating skills as 2D laparoscopy and a short learning curve. The price of 3D laparoscopy is also moderate, which makes the 3D laparoscopy more popular in China. Transanal total mesorectal excision (taTME) by changing the traditional laparoscopic pelvic surgery approach, may have certain advantages for male cases with narrow pelvic and patients with large tumor, and it is in accordance with the technical concept of natural orifice, with less minimally invasive and better cosmetics, which can be regarded as a supplemental technique of the

    Gynecologic cancers present unusual opportunities to explore the fruits of well-designed clinical trials to assess the value of existing treatment using a combined modality approach soon after diagnosis. Cancers of the ovary and uterus have well-defined, familiar natural histories. Pathways of spread are clear and reasons for treatment failure are often blatantly obvious. In the case of ovarian cancer, regional treatment with surgery and radiotherapy has been relatively ineffective and generally has not improved the survival statistics in the last two decades. Spread of tumor cells widely throughout the abdominal cavity outside radiation or surgical fields, even in patients with apparently early disease, is the obvious reason. Studies are underway to assess the impact of long-term postoperative adjuvant chemotherapy with L-phenylalanine mustard, an alkylating agent effective in patients with advanced disease, in early stages of ovarian cancer following surgery and or x-irradiation. The search is on for more effective drugs, or combinations of drugs, that could subsequently serve as more effective adjuvant treatments. In carcinoma of the uterine cervix, chemotherapy as an adjunct to surgery and/or radiotherapy in patients with localized, or locally inoperable disease has been poorly evaluated; little data are available and the value of many established drugs in patients with metastatic cervical cancer is undermined. Some recent evidence suggests the use of hydroxyurea, a drug that by itself is not effective in controlling tumor, may enhance the effect of radiotherapy in patients with Stage II disease. Uterine fundal cancer is often successfully treated by surgery alone. The data for the use of pre- or postoperative radiotherapy are open to considerable question. While the relative nontoxic progesterone compounds are effective in a small but significant fraction of patients with advanced uterine cancer, no properly designed clinical trial has truly evaluated their

    Despite the appeal of discovering the different strengths of various research methods, mixed methods research remains elusive in pediatric oncology nursing research. If pediatric oncology nurses are to succeed in mixing quantitative and qualitative methods, they need practical guidelines for managing the complex data and analyses of mixed methods research. This article discusses mixed methods terminology, designs, and key design features. Specific areas addressed include the myths about mixed methods research, types of mixed method research designs, steps involved in developing a mixed method research study, and the benefits and challenges of using mixed methods designs in pediatric oncology research. Examples of recent research studies that have combined quantitative and qualitative research methods are provided. The term mixed methods research is used throughout this article to reflect the use of both quantitative and qualitative methods within one study rather than the use of these methods in separate studies concerning the same research problem.

    In the oncology specialty, many factors can result in occupational stress in nursing professionals. As an attempt to controlling this situation, individuals may use coping strategies. Coping is a cognitive and behavioral effort one uses to face a stressful situation. The aims of this study were to identify the stressful factors regarding oncology nurses, and to verify what coping strategies they use. Two questionnaires were used: a demographic data inventory, designed by the researcher, and the Folkman and Lazarus coping strategies inventory. The results showed that the main stressful factors for oncology nurses are patient death (28.6%), emergency situations (16.9%), relationship issues with the nursing team (15.5%), and work-process situations (15.5%). In the studied population, the main coping strategy used was positive reappraisal.

    Women have an increasingly significant presence in the oncology physician workforce but remain underrepresented in leadership positions and at the senior levels of academic medicine. Initiatives to close these gaps are underway both in the United States and Europe. However, many areas for improvement remain on an organizational level and in the trenches of career development and mentorship for individual female oncologists in both community and academic settings. Solutions to advance women in the oncology workforce will involve policy initiatives by professional and funding organizations, individual initiatives by universities and practices to recognize and develop female leaders, an increased focus on teamwork and novel practice arrangements, and high-quality mentorship of young women entering the oncology field.

    Clinical imaging plays an essential role in cancer care and research for diagnosis, prognosis, and treatment response assessment. Major advances in imaging informatics to support medical imaging have been made during the last several decades. More recent informatics advances focus on the special needs of oncologic imaging, yet gaps still remain. We review the current state, limitations, and future trends in imaging informatics for oncology care including clinical and clinical research systems. We review information systems to support cancer clinical workflows including oncologist ordering of radiology studies, radiologist review and reporting of image findings, and oncologist review and integration of imaging information for clinical decision making. We discuss informatics approaches to oncologic imaging including, but not limited to, controlled terminologies, image annotation, and image-processing algorithms. With the ongoing development of novel imaging modalities and imaging biomarkers, we expect these systems will continue to evolve and mature.

    Full Text Available The growing demand and the degree of patient care in oncological outpatient services, as well as the complexity of treatment have had an impact on the workload of nurses. This study aimed at measuring the workload and productivity of nurses in an oncological outpatient service. An observational study using a work sampling technique was conducted and included seven nurses working in an oncological outpatient service in the south-eastern region of Brazil. A total of 1,487 intervention or activity samples were obtained. Nurses used 43.2% of their time on indirect care, 33.2% on direct care, 11.6% on associated activities, and 12% on personal activities. Their mean productivity was 88.0%. The findings showed that nurses in this service spend most of their time in indirect care activities. Moreover, the productivity index in this study was above that recommended in the literature.

    Restricted mouth opening (RMO) and trismus are terms commonly used in oral oncology in instances where there is difficulty in mouth opening. The term trismus in oral oncology is mainly used to indicate the radiation-induced fibrosis of the muscles of mastication. The treatment given for RMO as reported in the literature is given for muscular dysfunction trismus, whereas RMO in oral oncology can occur owing to various reasons other than muscular dysfunction. RMO occurs in various conditions of the oral cavity; in posterior pharyngeal infection, where it is termed reflectory trismus; in oral submucous fibrosis; in oral mucosal disorders; in the use of certain drugs; and in minor dental procedures of the posterior oral cavity. The usage of the term trismus in all RMO cases would complicate the treatment; thus, the word should not be used in all RMO cases.

    There is increasing attention in the US healthcare system on the delivery of high-quality care, an issue central to oncology. In the report 'Crossing the Quality Chasm', the Institute of Medicine identified six aims for improving healthcare quality: safe, effective, patient-centered, timely, efficient and equitable. This article describes how current big data resources can be used to assess these six dimensions, and provides examples of published studies in oncology. Strengths and limitations of current big data resources for the evaluation of quality of care are also discussed. Finally, this article outlines a vision where big data can be used not only to retrospectively assess the quality of oncologic care, but help physicians deliver high-quality care in real time.

    Baron Esquivias, Gonzalo

    2015-01-01

    This book is designed for clinical cardiologists and other physicians working with cardiac patients, where specific specialized teams of cardio-oncologists are not available and who are called to perform a clinical consultation to evaluate both the cardiac condition and the eligibility for chemotherapy or radiotherapy treatment, and to evaluate if a cancer treatment produces toxic effects on a patient treated with chemo or radiotherapy and if appearance of new symptoms is due to this treatment. In recent years, progress in oncologic therapy has resulted in important developments and the prognostic improvement of patients with malignancy. The cornerstone of chemotherapy are the anthracyclines (and the analogue Mitoxantrone), that are direct cellular toxic agents and that are among the most powerful anti-neoplastic drugs, but their cardiac toxicity is well known. Significant breakthroughs in cancer therapy have also been achieved with the introduction of signalling inhibitors, such as VEGF inhibitors, HERB2 inh...

    Despite advances in cancer research, the majority of drug applications submitted to the U.S. Food and Drug Administration (FDA) are not approved. It is important to identify the concerns of the Oncologic Drugs Advisory Committee (ODAC) from rejected applications. All applications referred to the ODAC from 2001 to 2012 were reviewed. Of 46 applications, 31 (67%) were for full and 15 (33%) were for supplemental approval, 34 (74%) were for solid and 12 (26%) were for hematologic tumors. In all, 22 (48%) were not approved. ODAC comments addressed missing or inadequate data (65%), excessive toxicity (55%), inappropriate study endpoints (45%), poor study design (40%), and insufficient sample size (30%). To define efficacy, 19 applications used response rates (RR) (median = 38%), and 19 applications used hazard ratios (HR) (median = 0.67). For all organ systems combined, the median cumulative grade 3 or 4 toxicity was 64%. Drugs with higher RR, lower HR, and lower toxicity were more likely to be approved versus other drugs (89% vs. 45%; p = .02). Over time (2001-2004, 2005-2008, 2009-2012), there was an increase in the following: number of applications submitted for review (from 11 to 12 to 23, respectively), number of approvals (from 6 to 6 to 12, respectively), and proportion of trials using progression-free survival as a primary endpoint (from 0% to 50% to 70%, respectively; p = .01). Of all applications, common ODAC concerns included inadequate data, excessive toxicity, and inappropriate study endpoints. Over time, there was an approximate doubling of FDA application submissions and approved oncology drugs.

    Full Text Available Background. Audits of oncology units are part of all quality-assurance programmes. However, they do not always come across as pragmatic and helpful to staff. Objective. To report on the results of an online survey on the usefulness and impact of an audit process for oncology units. Methods. Staff in oncology units who were part of the audit process completed the audit self-assessment form for the unit. This was followed by a visit to each unit by an assessor, and then subsequent personal contact, usually via telephone. The audit self-assessment document listed quality-assurance measures or items in the physical and functional areas of the oncology unit. There were a total of 153 items included in the audit. The online survey took place in October 2016. The invitation to participate was sent to 59 oncology units at which staff members had completed the audit process. Results. The online survey was completed by 54 (41% of the 132 potential respondents. The online survey found that the audit was very or extremely useful in maintaining personal professional standards in 89% of responses. The audit process and feedback was rated as very or extremely satisfactory in 80% and 81%, respectively. The self-assessment audit document was scored by survey respondents as very or extremely practical in 63% of responses. The feedback on the audit was that it was very or extremely helpful in formulating improvement plans in oncology units in 82% of responses. Major and minor changes that occurred as a result of the audit process were reported as 8% and 88%, respectively. Conclusion. The survey findings show that the audit process and its self- assessment document meet the aims of being helpful and pragmatic.

    There are approximately 82 radiation oncology residency programs in the United States, which provide training opportunities for about 400 residents. All accredited radiation oncology residency programs must have at least one basic scientist on the faculty, and it is these individuals who often assume, wholly or in part, the responsibility of teaching radiation and cancer biology to radiation oncology residents in preparation for the American College of Radiology (ACR) In-Training Examination in Radiation Oncology and the American Board of Radiology (ABR) written examinations. In response to a perceived lack of uniformity in radiation and cancer biology curricula currently being taught to residents and a perceived lack of guidance for instructors in formulating course content for this population, a special session was presented at the Forty-eighth Annual Radiation Research Society meeting on April 23, 2001. The session, entitled "Toward a Consensus on Radiobiology Teaching to Radiation Oncology Residents", was focused on issues related to teaching radiobiology to radiation oncology residents and targeted for individuals who actively teach radiation and cancer biology as well as coordinators of residency training programs. The speakers addressed current challenges and future problems facing instructors and programs. Among these were lack of feedback on resident performance on ABR and ACR written examinations and on course content, uncertainty about what topics residents must know to pass the ABR examination, and, in the near future, a reduction (due to retirement) of instructors qualified to teach radiobiology. This article provides a synopsis of the information that was presented during that session, offers a glimpse into how the ABR and ACR examinations are prepared and details of the content of past and future examinations, and summarizes the activities of the Joint Working Group on Radiobiology Teaching which was formed to educate instructors, to establish a
