Level of Scientific Evidence Underlying the National Comprehensive Cancer Network Clinical Practice Guidelines for Hematologic Malignancies: Are We Moving Forward?

Background: The level of scientific evidence in National Comprehensive Cancer Network (NCCN) guidelines for malignant hematological conditions haven't been recently investigated. We describe the distribution of categories of evidence and consensus (EC) among the 10 most common hematologic malignancies with regard to recommendations for staging, initial and salvage therapy, and surveillance. Methods: We reviewed the level of evidence for the 10 most common hematological malignancies by incidence in the United States as of 2020. The NCCN definitions for EC are: category 1, high level of evidence, such as randomized controlled trials, with uniform consensus; category 2A, lower level of evidence with uniform consensus; category 2B, lower level of evidence without a uniform consensus but with no major disagreement; and category 3, any level of evidence but with major disagreement. We compared our results with previously published results from 2011. Results: Of 1353 recommendations, 5%, 91%, 4%, and 1% fell into EC categories 1, 2A, 2B, and 3, respectively, while in 2011 the comparable percentages were 3%, 93%, 4%, and 0%, respectively. Recommendations with category 1 EC were found in all guidelines, except for Burkitt lymphoma. Of all therapeutic recommendations, 6.3% were category 1 EC, with the majority of these (56.4%) pertaining to initial therapy. Guidelines with highest proportions of therapeutic recommendations with category 1 EC were multiple myeloma (12.4%), chronic lymphocytic leukemia/small lymphocytic lymphoma (6.9%), and acute myeloid leukemia (5.6%). Conclusions: Recommendations in the 2020 NCCN guidelines are largely developed from lower levels of evidence but with uniform expert opinion, underscoring the urgent need and available opportunities to expand the current evidence base in malignant hematological disorders.

MO1037WOMEN REPRESENTATION IN CLINICAL PRACTICE GUIDELINES AMONG MAJOR NEPHROLOGY GUIDELINES

Background and Aims

While the percentage of women entering nephrology has increased over the years, women representation and sex disparities in the authorship of major nephrology Clinical practice guidelines (CPG) has not been examined. Our study evaluates current sex disparities and women representation, and the nationalities of women authors in nephrology CPGs developed by the Kidney Disease: Improving Global Outcomes (KDIGO), Kidney Disease Outcomes Quality Initiative (KDOQI), and the European Renal Best Practice (ERBP), the official guideline body of the ERA-EDTA.

Method

We examined the number of female versus male guideline workgroup members (panelists) for all available CPGs in each of the three organizations as of Dec. 2020, which are available on their respective websites. We discerned the sex of the panelists based on google search and their affiliated institutional websites. We obtained the nationalities of the workgroup members from the authorship information of the respective CPG.

Results

Of the total 488 panelists in all three organizations, 115 (23.6%) were females and 373 (76.4%) males. KDIGO had 184 panelists, of which 46 (25%) were females. The CPGs with the highest and the least women representation are ‘Diabetes in Chronic Kidney Disease (CKD)’ (41.2%) and ‘Anemia in CKD’ (11.8%), respectively. The countries with the highest number of women representations are the USA (20), followed by Canada (6), and China (4). In KDOQI, 39 (31%) of 127 panelists were female. While CPGs related to ‘Evaluation and management of CKD’ and ‘Nutrition in children with CKD’ each had 50% female panelists, ‘Blood pressure management in CKD’ CPG had 10% female panelists. 28 (72%) of the total 39 women were from the USA. The ERBP had 30 (17%) females of the total 177 panelists. ‘CKD in older patients’ CPG comprised 42.1% female panelists. CPGs for ‘Glycemic control in diabetes’ and ‘Glucose lowering drugs in diabetes’ had no female panelists. Belgium and UK each had six women representatives, while France and The Netherlands 4 women representatives each.

Conclusion

The guidelines developed by the most prominent organizations – KDIGO, KDOQI, and ERA-EDTA have less than 25% women representation. While it is encouraging to note that there is more women representation in some of the CPGs developed by KDIGO in 2020, evaluating the barriers contributing to the under-representation of women in major nephrology organizations is warranted. Also notable is a lack of women representation from developing countries.

Trends in female representation in clinical practice guidelines (CPGs) among major cancer organizations

11006

Background: While women representation and sex disparities in National Comprehensive Cancer Network (NCCN) and European Society of Medical Oncology (ESMO) has been studied in a limited set of CPGs, the sex representation and disparity trend over time among all NCCN and ESMO CPG panelists has not been studied. Our study evaluates the current sex disparities and female representation for all NCCN and ESMO CPGs as of 2020 and compared it to the 2010 CPGs of both organizations. Methods: The 2010 and 2020 version of NCCN and ESMO CPGs were examined from their respective websites and archives. We catalogued the number of female versus male panelist for each CPG. We discerned the sex of the panelists based on google search and the panelists’ affiliated institutional websites. Results: 60 NCCN (2020), 51 NCCN (2010), 78 ESMO (2020) and 55 ESMO (2010) CPGs inclusive of all cancers by site, detection prevention and risk reduction, supportive care, and guidelines for specific population were reviewed. NCCN 2020 CPGs had 55.5% female representation. 35 (58%) NCCN CPGs had predominant female representation (>50% of the members being female) whereas 24 CPG (40%) were male predominant (>50% of the members being male). Solid tumors had 24 CPGs with male predominance and hematological malignancies had 14 CPGs with female predominance. Cancers specific to women had higher proportion of female panelist. NCCN 2010 CPGs had 27.1% female representation. Both solid tumors and hematological malignancies had male predominance (82% and 75% respectively). Breast cancer screening, palliative care and older adult oncology CPGs were female predominant. ESMO 2020 had 27.8% female representation. Both solid tumors (37 CPGs) and hematological malignancies (17 CPGs) had predominant male representation (72% and 85% respectively). Breast and ovarian cancer CPGs were female predominant. ESMO 2010 had 23.2% female representation. Male representation was predominant in both solid tumors (35 CPGs) and hematological malignancies (9 CPGs). Breast, cervical and ovarian cancer CPGs were female predominant. Conclusions: Over the last decade, proportion of female panelists in NCCN CPGs has doubled with more than 50% representation among its 60 CPGs, indicating adequate representation of women. In ESMO, although there has been a significant improvement in female representation in hematological malignancies over time, it continues to have overall female underrepresentation (<30%).[Table: see text]

Conflicts of interest (COI) among the UpToDate oncology management authors

e13573

Background: UpToDate is an evidence based clinical resource designed to provide current clinical information. It is a widely used clinical practice tool providing evidenced based recommendations for diagnosis, management, and therapy. The extent of COI among the UpToDate authors has not been well studied. Our study evaluated the extent of COI of UpToDate authors involved in medical management recommendations for the 10 most common cancers in United States. Methods: We examined the latest November 2020 version of the UpToDate clinical management recommendations for 10 most common cancers. Using disclosure lists, we catalogued COIs for participants in each work group. The categories included: Category I- Grant/Research/Clinical Trial Support; Category II- Consultant/Scientific Advisory Boards/Expert witness; Category III- Speakers Bureau; Category IV- Equity Ownership/Stock Options/Patent holder/Employment/Other Financial Interest; and Category V- Spouse/Domestic Partner/Dependent Potential Conflict. We cataloged the companies/institutions involved in each disclosure. An “episode” describes 1 instance of participation of an individual in 1 company in 1 category for each cancer section. Results: There was a total of 207 authors including section and deputy editors of oncology management section. All authors completed their COI disclosures (100%). 128 (62%) of a total of 207 individuals reported COIs. A total of 1343 episodes were disclosed. We found that each author had an average of 10.49 episodes overall. Authors involved in Category I, II, III, IV & V were 6.3%, 13.5%, 3.2%, 4.7% and 1.6% respectively. 29.36% authors were involved both in Category I and II. A total of 672 company affiliations were associated with COI disclosure. AstraZeneca (6.10%), Merck (4.31%) and Novartis (2.68%) were the companies most frequently reported. The guideline with the maximum episodes (223) was prostate cancer. Conclusions: COIs are prevalent among authors of UpToDate clinical management recommendations. More than ½ of the participants disclosed at least 1 COI, but there appears to be a substantial number of experienced experts without COIs. Further research studies are necessary to determine the impact of these COIs on clinical practice patterns and resource utilization. Distribution of COI and total episodes.[Table: see text]

Self-reported Financial Conflict of Interest in Nephrology Clinical Practice Guidelines

INTRODUCTION

There is ongoing controversy concerning the potential influence of industry and financial conflict of interest (FCOI) in the development of clinical practice guidelines (CPG). The influence of industry in renal guideline development has been discussed in the past with emphasis on the National Kidney foundation (NKF) and Kidney and Dialysis Outcomes Quality Initiative guidelines. In this study we evaluate the self-reported FCOI among guideline panel members in Kidney Disease: Improving Global Outcomes (KDIGO) CPGs.

METHODS

We examined 10 of the most recent KDIGO CPGs developed between 2009 and 2018. Using disclosure lists, we catalogued FCOIs for panelists for each individual CPG. The categories were Advisor/Consultant, Honoraria, Travel Stipend, Grant/Research Support, Speaker, Equity Interest, Employee, Board of Trustees, Royalties, Advisory Board, Employment, Ownership, Data Monitoring Committee, Expert Testimony, and Development of Education Materials. We also reviewed FCOIs for members of evidence review team (ERT). We also catalogued the company involved in each disclosure. One conflict describes 1 instance of participation of an individual in 1 category in each guideline. "Company" describes a commercial, industry, or institute affiliation reported in each episode.

RESULTS

One hundred two (66.4%) of the total 151 panelists reported FCOI. A total of 662 conflicts were disclosed. Being a consultant or advisor was the most common category. One hundred fifty-one companies were associated with FCOI disclosure. One company was most frequently reported, involving 60 (9%) of 662 conflicts. Of the 52 members in the ERT, there was 1 instance of FCOI.

CONCLUSION

FCOI is prevalent in KDIGO guidelines with almost two thirds of the panelists self-reporting FCOI. The evidence review team had only 1 instance of FCOI.

Financial conflicts of interest among National Comprehensive Cancer Network clinical practice guideline panelists in 2019

BACKGROUND

Clinical practice guidelines (CPGs) are evidence-based guidelines that serve as a standard of care in oncology practice, reimbursements, and quality improvement initiatives. To our knowledge, the extent of financial conflicts of interest (FCOIs) in National Comprehensive Cancer Network (NCCN) guidelines have not been systemically evaluated. The current study evaluated the extent of FCOIs in the NCCN CPGs for the most common malignancies in the United States.

METHODS

The authors examined the latest 2019 versions of the NCCN CPGs for the 10 most common cancers by incidence in the United States. Using disclosure lists, they catalogued the FCOIs for the panelists under various categories outlined in the CPG. The authors also tabulated the companies and institutions involved in each panel disclosure. An "episode" describes 1 instance of participation of a panelist in 1 company in 1 category of each guideline. "Affiliation" describes an industrial, commercial, or institutional affiliation reported by a panelist in each episode.

RESULTS

Of the 491 panelists on the CPG panel, 483 (98.3%) completed FCOI disclosures. A total of 224 (46.4%) reported at least 1 FCOI episode. A total of 1103 episodes were disclosed with an average of 4.9 episodes reported per panelist with FCOIs. Acting as part of scientific advisory boards, as a consultant, or as an expert witness was the most common FCOI category (19.9%). A total of 191 companies were associated with 1103 episodes of FCOI. The top companies were Bristol-Myers Squibb, Merck, Genentech, and AstraZeneca. Among cancers, the prevalence of FCOIs was highest for lung cancer (56%), bladder cancer (52%), pancreatic cancer (52%), non-Hodgkin lymphoma (50%), kidney cancer (49%), colorectal cancer (43%), breast cancer (42%), melanoma (40%), prostate cancer (38%), and uterine cancer (32%). Among the panelists with FCOIs, 26%, 17%, and 57%, respectively, reported 1, 2, and >3 episodes. There were 127 episodes noted among the CPG chairs and/or vice chairs who reported FCOIs (mean, 6.4 episodes). The chairs and/or vice chairs of CPGs for uterine cancer, pancreatic cancer, melanoma, and prostate cancer were not found to have any FCOIs.

CONCLUSIONS

FCOIs are very prevalent among NCCN CPG panelists. In nearly one-half of the CPGs, the majority of the panelists had at least 1 FCOI. Greater than one-half of the CPG chairs and/or vice chairs reported multiple FCOIs. Further research studies are necessary to determine the impact of these FCOIs.

Impact of adjuvant chemotherapy on outcomes in appendiceal cancer

BACKGROUND

The impact of using adjuvant chemotherapy following cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with appendiceal adenocarcinoma is not known. The aim of this study was to assess the impact of adjuvant chemotherapy following complete cytoreduction in patients with appendiceal adenocarcinoma.

METHODS

Retrospective medical record review of all patients with appendiceal adenocarcinoma treated at our institution between 2006 and 2015. Kaplan-Meier plots were used to summarize overall survival (OS) and relapse-free survival over time, and log-rank tests and Cox proportional hazards models were used to test for differences in survival between groups.

RESULTS

A total of 103 patients with appendiceal adenocarcinoma received care at our institution during the study period. Complete cytoreduction (cytoreductive score 0-1) was achieved in 68 patients (66%). Of these 68 patients, 26 received adjuvant chemotherapy. The most common regimens were capecitabine (n = 11), capecitabine plus oxaliplatin (n = 7), and 5-FU plus oxaliplatin (n = 6). Tumor histopathology and grade, and the ability to achieve complete cytoreduction were significant predictors of overall survival. The median OS for non-low-grade and well-differentiated tumor patients who received adjuvant chemotherapy following complete cytoreduction was 9.03 years, compared to 2.88 years for patients who did not receive adjuvant chemotherapy (P = .02). Among low-grade and well-differentiated tumor patients who underwent complete cytoreduction, there was no statistically significant difference in OS between those who received adjuvant chemotherapy and those who did not.

CONCLUSION

Adjuvant chemotherapy seems to have benefit in appendiceal cancer patients with non-low-grade or well-differentiated tumor type but not in low-grade or well-differentiated tumors.

Acute Interstitial Nephritis and Checkpoint Inhibitor Therapy

Background

The objective of this case cohort study was to describe our experience in the care of patients with immune checkpoint inhibitor–related acute interstitial nephritis (ICI-AIN) including rechallenge.

Methods

A descriptive case series of patients that received an ICI and had an AKI (defined as a ≥1.5-fold increase in serum creatinine) as an immune-related adverse event (irAE), with biopsy-proven or clinically suspected ICI-AIN from January 1, 2014 to December 1, 2018 at Mayo Clinic, Rochester. We studied details regarding diagnosis, clinical course, management, and outcomes of rechallenge of immunotherapy. Complete response (CR) was defined as return of kidney function back to baseline or <0.3 mg/dl above baseline creatinine; partial response (PR) was defined as creatinine >0.3 mg/dl from baseline, but less than twofold above the baseline by the end of steroid course.

Results

A total of 14 cases of biopsy-proven (35%) or clinically suspected (65%) ICI-AIN was identified. All patients had their ICI withheld and 12 patients received steroids. Steroid regimens were highly variable. The starting equivalent dose of prednisone was higher in those that had a CR versus a PR (median 0.77 mg/kg versus 0.66 mg/kg). Proton pump inhibitors (PPIs) were used in 11 patients and were stopped in eight (73%) patients at the time of the AKI event. A CR was seen in five (63%) of the eight patients who discontinued PPIs. Rechallenge was attempted in four of the 14 patients: three were successful with no recurrence of AKI, but one patient had recurrent AKI and fatal pneumonitis.

Conclusions

Careful review, withholding ICI and concomitant known AIN-inducing medications, along with prompt initial steroid management were the key in complete renal kidney recovery. A kidney biopsy should be strongly considered. Rechallenge of immunotherapy after a kidney irAE, although challenging, is possible and would need careful evaluation on an individual basis.

Financial conflicts of interest among the National Comprehensive Cancer Network (NCCN) Clinical Practice Guideline (CPG) Panelists in 2019

15

Background: CPG are evidence-based guidelines, which serve as a standard of care in practice, quality improvement, and reimbursement. The extent of financial conflicts of Interest (FCOI) in NCCN guidelines has not been recently evaluated. Our study evaluated the extent of FCOI in the NCCN CPG among the 10 most common malignancies in the US. Methods: We examined the latest 2019 version of the NCCN CPG for the 10 most common cancers by incidence in the US. Using disclosure lists, we catalogued the FCOIs for the panelists under various categories outlined in the CPG. We also tabulated the companies/institutions involved in each disclosure. An “episode” describes 1 instance of participation of a panelist in 1 company in 1 category of each guideline. “Affiliation” describes a commercial, industry, or institute affiliation reported by a panelist in each episode. Results: Of the 491 panelists on the CPG, 483 (98.3%) completed FCOI disclosures. 224 (46.38%) reported at least 1 FCOI. A total of 1,103 episodes were disclosed with an average of 4.9 episodes per panelist with FCOI. Being a part of scientific advisory boards, consultant, or expert witness was the most common FCOI category (19.9%). A total of 191 companies were associated with 1,103 episodes of FCOI. The top companies were Bristol Myers Squibb, Merck, Genentech and AstraZeneca. Among the top 10 cancers, the prevalence of FCOI were lung (56%), bladder (52%), pancreatic (52%), non-Hodgkin lymphoma (50%), kidney (49%), colorectal (43%), breast (42%), melanoma (40%), prostate (38%), and uterine (32%). Among the panelists with FCOI, 26%, 17%, and 57% reported 1, 2, and > 3 episodes, respectively. There were 127 episodes among the CPG chairs/vice chairs who reported FCOI (mean 6.4). The chairs/vice chairs of uterine, pancreatic, melanoma, and prostate cancer CPG did not have any FCOI. Conclusions: FCOI are very prevalent among the top 10 NCCN CPG panelists. In almost half of the CPG, the majority of the panelists had at least 1 FCOI. Over half of the CPG chairs/vice chairs reported multiple FCOI. Further studies are necessary to determine the impact of these FCOI.

MON-LB069 When a Routine Postoperative Internal Medicine Consultation Unearths a Hidden Diagnosis

Although rare in incidence, acromegaly can present with secondary osteoarthritis due to anabolic effects of Growth Hormone (GH). The diagnosis can be potentially missed until later in its clinical course, leading to a lost opportunity to prevent further complications and irreversible changes attributed to acromegaly. A 32-year-old patient with history of mild Type 1 Von Willebrand (VW) disease and severe crippling bilateral osteoarthritis of the hips was admitted for elective right hip replacement. The etiology of the osteoarthritis was not clear, but was felt to be unlikely to be related to VW disease, in the absence of hemarthrosis. A routine Internal Medicine consult was requested by the Orthopedics service for co-management of the patient postoperatively as he was on placed on VW factor infusion. Intraoperative findings were notable for severe osteopenia and destructive deformity of the femoral head. On examination, the patient was moderately built with largely normal systems examination. Closer examination revealed prominent supraciliary arches and nose. Large hands were noted with sausage like appearing digits. On further questioning, patient mentioned that his shoe size has increased to size 13 from size 10 in the last 3-4 years. A comparison of a previous picture of his face (5 yrs. ago) to now confirmed the pronounced changes in facial features. He recalled his dentist mentioning about significant spacing between his teeth a year ago. An insulin like growth factor 1 (IGF1) level was ordered as a first part of the work up for Acromegaly. The level returned back at 1448 ng/ml (53-332 ng/ml). An MRI scan of the brain revealed a large macro-adenoma extending onto the right cavernous sinus and displacing the optic chiasma. He was referred to the pituitary clinic for further work up and ultimately underwent a partial 2 stage trans nasal endoscopic resection of the tumor followed by fractionated radiotherapy. He continues to be on octreotide and pegvisomant. With the increase in childhood obesity, there has been an increased incidence of osteoarthritis in young patients. The need for joint replacement in relatively young patients has also increased. While it is important to pursue joint replacement surgeries in these patients to prevent disability, careful evaluation of the cause of OA must be looked into, especially in young patients.
