The importance of quality assurance in surgical oncology

SUCCOR quality: validation of ESGO quality indicators for surgical treatment of cervical cancer

OBJECTIVE

To evaluate whether compliance with European Society of Gynaecological Oncology (ESGO) surgery quality indicators impacts disease-free survival in patients undergoing radical hysterectomy for cervical cancer.

METHODS

In this retrospective cohort study, 15 ESGO quality indicators were assessed in the SUCCOR database (patients who underwent radical hysterectomy for International Federation of Gynecology and Obstetrics (FIGO) stage 2009 IB1, FIGO 2018 IB1, and IB2 cervical cancer between January 2013 and December 2014), and the final score ranged between 0 and 16 points. Centers with more than 13 points were classified as high-quality indicator compliance centers. We constructed a weighted cohort using inverse probability weighting to adjust for the variables. We compared disease-free survival and overall survival using Cox proportional hazards regression analysis in the weighted cohort.

RESULTS

A total of 838 patients were included in the study. The mean number of quality indicators compliance in this cohort was 13.6 (SD 1.45). A total of 479 (57.2%) patients were operated on at high compliance centers and 359 (42.8%) patients at low compliance centers. High compliance centers performed more open surgeries (58.4% vs 36.7%, p<0.01). Women who were operated on at centers with high compliance with quality indicators had a significantly lower risk of relapse (HR=0.39; 95% CI 0.25 to 0.61; p<0.001). The association was reduced, but remained significant, after further adjustment for conization, surgical approach, and use of manipulator surgery (HR=0.48; 95% CI 0.30 to 0.75; p=0.001) and adjustment for adjuvant therapy (HR=0.47; 95% CI 0.30 to 0.74; p=0.001). Risk of death from disease was significantly lower in women operated on at centers with high adherence to quality indicators (HR=0.43; 95% CI 0.19 to 0.97; p=0.041). However, the association was not significant after adjustment for conization, surgical approach, use of manipulator surgery, and adjuvant therapy.

CONCLUSIONS

Patients with early cervical cancer who underwent radical hysterectomy in centers with high compliance with ESGO quality indicators had a lower risk of recurrence and death.

Quality assurance and quality control in surgical oncology

Even though surgery has remained a key component within multi-disciplinary cancer care, the expectations have changed. Instead of serving as a modality to free a patient of a mass at all means and at the risk of high morbidity, modern cancer surgery is expected to provide adequate tumor clearance with lowest invasiveness. This review summarizes the evidence on quality assurance in surgical oncology and gives a comprehensive overview of quality improvement tools.

Assessment of ESGO Quality Indicators in Cervical Cancer Surgery: A Real-World Study in a High-Volume Chinese Hospital

The ESGO developed a list of fifteen quality indicators for cervical cancer surgery in order to audit and improve clinical practice in 2020. However, data from the developing countries with high incidence rates of cervical cancer is still lacking. Therefore, we conducted a retrospective study of 7081 cases diagnosed as cervical cancer between 2014 and 2019 in a Chinese single center according to the quality indicators proposed by ESGO. A total of 5952 patients underwent radical procedures, with an average of 992.0 per year. All surgeries were performed or supervised by a certified gynecologic oncologist as surgical qualification grading system has been established. Compared with the low-volume group, patients in the high-volume group (≥15 cases/year) had a shorter hospital stay (P<0.001), more free surgical margins (P=0.031), and less complications (P<0.001), but the 5-year recurrence-free survival and overall survival rates were similar (P>0.05). Treatment was not planned at a multidisciplinary team meeting but with the consultation system. The required preoperative workup was incomplete in 19.7% of patients with pelvic MRI and 45.7% of patients with PET-CT. A total of 1459 (20.6%) patients experienced at least one complication after surgery. The CDC grade IIIb or higher complications occurred in 80 patients, accounting for 5.5% complications. The urological fistula rate within 30 postoperative days were 0.3%. After primary surgical treatment, 97.4% patients had clear vaginal and parametrial margins. After restaging FIGO 2009 to FIGO 2018 system, 14.7% patients with a stage T1b disease were T-upstaged. After a median follow-up of 42 months, recurrence occurred in 448 patients, and 82.1% patients recurred within 2 years. The 2-year RFS rate of patients with pT1b1N0 was 97.3% in 2009 FIGO staging system. Lymph node staging was performed in 99.0% patients with a stage T1 disease. After a primary surgical treatment for a stage pT1b1N0 disease, 28.3% patients received adjuvant chemoradiotherapy. Above all, most of quality indicators reached the targets, except four quality indicators. The quality indicators of ESGO should be popularized and applied in China to guarantee quality of surgery.

Personalising the risk of conversion from laparoscopic to open hysterectomy in benign conditions: Development and external validation of risk prediction models

OBJECTIVE

To develop and validate novel prediction models to personalise the risk of conversion from laparoscopic to open hysterectomy in benign conditions.

DESIGN

Retrospective cohort study.

SETTINGS

English NHS Hospitals between 2011 and 2018.

POPULATION

68 752 women undergoing laparoscopic hysterectomy for benign conditions.

METHODS

We developed two multivariable logistic models using readily available clinical information, one for the pre-operative setting and another for operative decision-making using additional surgical information, using 2011-2016 data in five regions (24 806 women). We validated them (a) temporally in the same regions using 2017-2018 data (12 438 women); (b) geographically in the same time-period using data from three different regions (22 024 women); and (c) temporally and geographically using 2017-2018 data in three different regions (9484 women).

MAIN OUTCOME MEASURES

Conversion from laparoscopic to open hysterectomy.

RESULTS

Conversions occurred in 6.8% (1687/24 806) of hysterectomies in the development group, and in 5.5% (681/12 438) in the temporal, 5.9% (1297/22 204) in the geographical and 5.2% (488/9484) in the temporal and geographical validation groups. In the development cohort, the area under the receiver operating characteristic curve values for the pre-operative and operative models were 0.65 and 0.67, respectively. In the validation cohorts the corresponding values were 0.65 and 0.66 (temporal), 0.66 and 0.68 (geographical) and 0.65 and 0.68 (temporal and geographical), respectively. Factors predictive of conversion included age, Asian ethnicity, obesity, fibroids, adenomyosis, endometriosis and adhesions. Adhesions were the most predictive (odds ratio 2.54, 95% confidence interval 2.22-2.90).

CONCLUSION

The models for predicting conversions showed acceptable performance and transferability.

TWEETABLE ABSTRACT

Novel tool to personalise the risk of conversion from laparoscopic to open hysterectomy in benign conditions.

Textbook outcome and survival of robotic versus laparoscopic total gastrectomy for gastric cancer: a propensity score matched cohort study

Textbook outcome is a composite quality measurement of short-term outcomes for evaluating complex surgical procedures. We compared textbook outcome and survival of robotic total gastrectomy (RTG) with those of laparoscopic total gastrectomy (LTG). We retrospectively reviewed 395 patients (RTG, n = 74; LTG, n = 321) who underwent curative total gastrectomy for gastric cancer via minimally invasive approaches from 2009 to 2018. We performed propensity score matched analysis to adjust for potential selection bias. Textbook outcome included a negative resection margin, no intraoperative complication, retrieved lymph nodes > 15, no severe complication, no reintervention, no unplanned intensive care unit admission, hospitalization ≤ 21 days, no readmission after discharge, and no postoperative mortality. Survival outcomes included 3-year overall and relapse-free survival rates. After matching, 74 patients in each group were selected. Textbook outcome was similar in the RTG and LTG groups (70.3% and 75.7%, respectively), although RTG required a longer operative time. The quality metric least often achieved was the presence of severe complications in both groups (77.0% in both groups). There were no differences in the 3-year overall survival rate (98.6% and 89.7%, respectively; log-rank P = 0.144) and relapse-free survival rate between the RTG and LTG groups (97.3% and 87.0%, respectively; log-rank P = 0.167). Textbook outcome and survival outcome of RTG were similar to those of LTG for gastric cancer.

European Society of Gynaecological Oncology quality indicators for surgical treatment of cervical cancer

BACKGROUND

Optimizing and ensuring the quality of surgical care is essential to improve the management and outcome of patients with cervical cancer.To develop a list of quality indicators for surgical treatment of cervical cancer that can be used to audit and improve clinical practice.

METHODS

Quality indicators were developed using a four-step evaluation process that included a systematic literature search to identify potential quality indicators, in-person meetings of an ad hoc group of international experts, an internal validation process, and external review by a large panel of European clinicians and patient representatives.

RESULTS

Fifteen structural, process, and outcome indicators were selected. Using a structured format, each quality indicator has a description specifying what the indicator is measuring. Measurability specifications are also detailed to define how the indicator will be measured in practice. Each indicator has a target which gives practitioners and health administrators a quantitative basis for improving care and organizational processes.

DISCUSSION

Implementation of institutional quality assurance programs can improve quality of care, even in high-volume centers. This set of quality indicators from the European Society of Gynaecological Cancer may be a major instrument to improve the quality of surgical treatment of cervical cancer.

Impact of central surgical review in a study of malignant germ cell tumors

BACKGROUND

Verification of surgical staging has received little attention in clinical oncology trials. Central surgical review was undertaken during a study of malignant pediatric germ cell tumors.

METHODS

Children's Oncology Group study AGCT0132 included central surgical review during the study. Completeness of submitted data and confirmation of assigned stage were assessed. Review responses were: assigned status confirmed, assignment withheld pending review of additional information requested, or institutional assignment of stage disputed with explanation given. Changes in stage assignment were at the discretion of the enrolling institution.

RESULTS

A total of 206 patients underwent central review. Failure to submit required data elements or need for clarification was noted in 40%. Disagreement with stage assignment occurred in 10% with 17/21 discordant patients reassigned to stage recommended by central review. Four ovarian tumor patients not meeting review criteria for Stage I remained in that stratum by institutional decision. Two-year event free survival in Stage I ovarian patients was 25% for discordant patients compared to 57% for those meeting Stage I criteria by central review.

CONCLUSIONS

Central review of stage assignment improved complete data collection and assignment of correct tumor stage at study entry, and allowed for prompt initiation of chemotherapy in patients determined not to have Stage I disease.

Evaluating population-based breast cancer surgical practice in real time with a web-based synoptic operative reporting system

BACKGROUND

A Web-based synoptic operative reporting system (WebSMR) incorporates implicit guidelines and real-time feedback of a surgeon's practice compared with provincial data. This study compares rates of total mastectomy (TM) between the overall provincial and WebSMR patients and examines decision-making factors in WebSMR patients.

METHODS

Patients treated for invasive breast cancer (2007 to 2011) were identified from WebSMR and the Alberta Cancer Registry. Reports include surgery type and reasons for TM.

RESULTS

Among 5,787 patients in WebSMR (2007 to 2011), TM rate decreased from 48% to 42% (P < .001). In 2011, the provincial cancer registry recorded a 56% TM rate compared to 42% in WebSMR patients. Patient preference accounted for 36% in the latter group.

CONCLUSIONS

In WebSMR patients, TM rates were lower than the overall provincial rate and decreased significantly during the study period. Reasons are unclear, but guidelines and real-time feedback likely plays a role.

Clinical relevance of conversion rate and its evaluation in laparoscopic hysterectomy

STUDY OBJECTIVES

To estimate the current conversion rate in laparoscopic hysterectomy (LH); to estimate the influence of patient, procedure, and performer characteristics on conversion; and to hypothesize the extent to which conversion rate can act as a means of evaluation in LH.

DESIGN

Prospective cohort study (Canadian Task Force classification II-2).

SETTING

The study included 79 gynecologists representing 42 hospitals throughout the Netherlands. This reflects 75% of all gynecologists performing LH in the Netherlands, and 68% of all hospitals.

PATIENTS

Data from 1534 LH procedures were collected between 2008 and 2010.

INTERVENTION

All participants in the nationwide LapTop registration study recorded each consecutive LH they performed during 1 year.

MEASUREMENTS AND MAIN RESULTS

Conversion rate and odds ratios (OR) of risk factors for conversion were calculated. Conversions were described as reactive or strategic. The literature reported a conversion rate for LH of 0% to 19% (mean, 3.5%). In our cohort, 70 LH procedures (4.6%) were converted. Using a mixed-effects logistic regression model, we estimated independent risk factors for conversion. Body mass index (BMI) (p = .002), uterus weight (p < .001), type of LH (p = .004), and age (p = .02) had a significant influence on conversion. The risk of conversion was increased at BMI >35 (OR, 6.53; p < .001), age >65 years (OR, 6.97; p = .007), and uterus weight 200 to 500 g (OR, 4.05; p < .001) and especially >500 g (OR, 30.90; p < .001). A variation that was not explained by the covariates included in our model was identified and referred to as the "surgical skills factor" (average OR, 2.79; p = .001).

CONCLUSION

Use of estimated risk factors (BMI, age, uterus weight, and surgical skills) provides better insight into the risk of conversion. Conversion rate can be used as a means of evaluation to ensure better outcomes of LH in future patients.

Surgical specialization and training - its relation to clinical outcome for colorectal cancer surgery

RATIONALE, AIMS AND OBJECTIVES

Surgical sub-specialization has been considered to be a major factor in improving cancer surgery-related outcomes in terms of 5-year survival and disease-free intervals. In this article we have looked at the evidence supporting the improvement in colorectal cancer outcomes with 'colorectal specialists' performing colon and rectal surgery.

METHODS

A literature review was carried out using search engines such as Pubmed, Ovid and Cochrane Databases. Only studies looking at colorectal cancer outcome related to surgery were included in our review.

RESULTS

Specialist surgeons performing a high volume of colorectal cancer surgery demonstrated better 5-year survival rates in patients, with less local recurrence. This was most evident in surgery for rectal cancer, where an association with increased sphincter saving surgery was also seen. Total mesorectal excision is now the accepted treatment for rectal cancer and has markedly improved survival rates and decreased local recurrence.

CONCLUSION

The outcomes in colorectal surgery continue to steadily improve. The training of specialized colorectal surgeons is a major contributing factor towards this improvement.

The role of the pathologist in rectal cancer diagnosis and staging and surgical quality assessment

Since the introduction of the total mesorectal excision by Heald, many changes in the therapeutic management of rectal cancer have been incorporated. The multidisciplinary approach to colorectal cancer, integrated in a team of different specialists, ensures individualised treatment for each patient with rectal cancer. Therefore the role of the pathologist has acquired an important relevance, not only in diagnosing but also managing and evaluating the surgical specimen. The knowledge of preoperative staging, distance between tumour and anal verge or in patients subjected to a neoadjuvant treatment is necessary for the pathologist to make a detailed, accurate and good-quality report. Parameters such as the macroscopic quality of the mesorectum, the status of the circumferential resection margin and the lymph node harvest are considered basic criteria recommended by the current guidelines for the multidisciplinary team audit.

Opening the black box of cancer surgery quality: WebSMR and the Alberta experience

A web-based synoptic operative report, the WebSMR (Surgical Medical Record), was developed to define and improve the quality of cancer surgery. Surgeons accurately record the essential steps of an operation including important decision-making in an analyzable format. Outcomes can be reviewed with provincial aggregates for quality improvement and maintenance of certification. Future synoptic pathology and follow-up templates will open the "black box" of surgical processes to define quality indicators for the improvement of cancer outcomes.

Clinically important aspects of lymph node assessment in colon cancer

There has been considerable discussion in the literature regarding the importance and validity of lymph node retrieval and lymph node count for patients with colon cancer. In this article we summarize the importance of lymph node resection and assessment in contemporary colon cancer care, key clinical determinants of lymph node assessment, and discuss the role of lymph node assessment as a quality marker in colon cancer care.

The number of pelvic lymph nodes in the quality control and prognosis of radical hysterectomy for the treatment of cervical cancer

AIMS

To determine if the number of removed lymph nodes in radical hysterectomy with lymphadenectomy (RHL) influences survival of patients with early stage cervical cancer and to analyze the relation of different factors like patient age, tumour size and infiltration depth with the number of nodes examined in node-negative early stage cervical cancer patients.

METHODS

Of consecutive patients, who underwent RHL between January 1984 and April 2005, 331 had negative nodes (group A) without adjuvant therapy and 136 had positive nodes (group B). The Kaplan-Meier method and Cox regression model were used to detect statistical significance. Factors associated with excision of nodes were confirmed with linear regression models.

RESULTS

The median number of removed nodes was 19 and 18 for group A and group B, respectively. There was no significant relationship between the number of removed nodes and the cancer specific survival (CSS) or disease free survival (DSF) for patients of group A (p=0.625 and p=0.877, respectively). The number of removed nodes in group B was not significantly associated with the CSS (p=0.084) but it was for the DSF (p=0.014). Factors like patient age, tumour size and infiltration depth were not associated with the number of nodes.

CONCLUSIONS

No relation was found between the number of negative nodes examined after RHL for the treatment of early stage cervical cancer and CSS or DFS. However, a higher amount of removed lymph nodes leaded to a better DFS for patients with positive nodes. It is suggested that patients with positive nodes benefit from a complete pelvic lymphadenectomy and a sufficient yield of removed nodes.

Evaluation of a protocol-based management of rectal cancer

INTRODUCTION

The management of rectal cancer is multidisciplinary. We have devised and implemented a standardized protocol. This study was designed to evaluate the protocol and identify areas for improvement.

METHODS

All patients with a diagnosis of rectal cancer were staged preoperatively. Magnetic resonance imaging and computed tomography were used to predict whether surgical resection would be complete (RO) or involved (R1/2). Data were collected on preoperative adjuvant therapy, surgical procedure, and subsequent pathologic stage, including circumferential resection margin status.

RESULTS

Between January 2000 and October 2002, 163 patients were studied (107 male; median age, 70 (range, 60-77) years). One hundred and fifty seven patients underwent surgical excision for rectal cancer of whom 155 were discussed in the multidisciplinary meeting. One hundred seventeen patients (75 percent) had pelvic magnetic resonance scan and staging computed tomography of chest and abdomen, whereas 38 had computed tomography only. Seventy-seven tumors were predicted as R0 and 78 as likely R1/2. In the predicted RO group, 50 had surgery alone, 25 had short-course radiotherapy, and 2 had chemoradiotherapy. Twelve patients (15.5 percent) had involved circumferential resection margin on the histologic specimen. In the predicted R1/2 group (n = 78), 40 patients received chemoradiotherapy, 11 had short-course radiotherapy, and 27 had surgery alone. Thirty patients (38.4 percent) had involved circumferential resection margin. Circumferential margin involvement was seen in 11 of 40 patients (27.5 percent) who received chemoradiotherapy, 6 of 11 patients (54.5 percent) who received short-course preoperative radiotherapy, and 13 of 27 patients (48.1 percent) who had surgery alone.

CONCLUSIONS

Protocol-driven management of rectal cancer within the context of a multidisciplinary team has been demonstrated to work. Regular audit allows for modification and improvement of the protocol as newer management strategies evolve.

The influence of case load and the extent of resection on the quality of treatment outcome in gastric cancer

AIMS

The background was to analyse the influence of hospital- and surgeon volume and of the extent of resective procedures on the quality of early and late treatment results in gastric cancer.

METHODS

The literature was reviewed by searching the databases of Medline, Cancerlit, Pubmed and the Cochran register.

RESULTS

The levels of evidence showed wide variations. The influence of hospital volume was more important for the outcome than the case load of the individual surgeon. The extent of surgical resection should be adapted to histology--or stage. The value of systematic lymph node dissection is still under discussion.

CONCLUSIONS

We have found that the best treatment results were seen in high volume hospitals with experienced surgeons, even taking into account extended surgical procedures. Further studies are needed to define the optimal number of operations necessary to be carried out each year.

The computer synoptic operative report--a leap forward in the science of surgery

BACKGROUND

Quality of surgery is a proven prognostic factor in many tumors. It is critical to ensure that an effective method is in place to evaluate surgery accurately.

MATERIAL AND METHODS

A provincial Cancer Surgery Working Group designed and piloted a computerized synoptic operative report template (WebSMR) in rectal cancer surgery, to replace the standard narrative operative record (NR). This included a precise description of the procedure, data on demographics, diagnostic evaluation, staging, and functional measures. A total of 70 items for anterior resection (AR) and 63 items for abdominoperinal excision (APR) were included. The WebSMR was assessed for comparison with 40 NR randomly selected from seven hospitals in Southern Alberta from 2001 to 2003.

RESULTS

The NR contained 45.9% of the specified data elements and the WebSMR captured 99%. The most complete NR data (68.8% to 97%) concerned hospital and patient data, anesthetist and surgeon information, approach, and closure details. The important details of laparotomy and tumor resection were the next most complete data (33.5% to 47.5%) and the least complete (0 to 25%) concerned preoperative treatment, comorbidity, and metastatic and local assessment. All differences among these groups were statistically different (P < .001). No statistically significant differences were seen in the completeness of the NR according to the type of surgery (AR vs. APR; P = .1) or the dictating surgeon (colorectal vs. general vs. resident; P = .175). The time needed to complete the WebSMR test was only 6 minutes.

CONCLUSION

The science of surgical technique can be better measured by this unique instrument and will create accountability in surgery.

Management of colorectal cancers

The management of colorectal cancers, published in a recent issue of Effective Health Care, is reviewed.

Good practice and quality assurance in surgical oncology

The Halstedian era of radical surgical extirpation for solid tumours dominated the first half of the 20th century. But as understanding of cancer biology increased, a paradigm shift occurred which moved the focus away from extensive surgery towards less radical procedures. Although surgery is a recognised factor in local disease control, prognosis is now believed to be predetermined at the time of diagnosis by the presence of micrometastatic deposits. Modern cancer management consists of more skilled and conservative surgery to remove the primary tumour; adjuvant therapies are also given before and after the operation to target the subclinical metastatic deposits. The most important components of high-quality care in surgical oncology are: sound clinical judgment, surgical skill, and multidisciplinary care. These prerequisites are best achieved by specialisation, but high operative volume is not essential for excision of many types of tumour. Quality assurance using several readily available tools can ensure that the process of care from presentation to outcome is constantly improved and that institutional variations in number of cases and quality of care are monitored.
