– Nearly one-fourth of patients with early-onset colorectal cancer don’t get referrals for genetic counseling or testing, and although acceptance of genetic counseling has improved over the last 10 years, there is still a notable gap between referrals and uptake, investigators have found.

Among 791 patients with young- or early-onset colorectal cancer (YOCRC) seen at a large medical center from 2010 through 2019, 62.1% were referred for genetic counseling, but only 80.1% of this group followed through with the referrals by scheduling an appointment with a counselor or having genetic testing performed, reported Hareem Syed, MD, from the department of internal medicine at the Cleveland Clinic.

“Our findings highlight the need for health systems to implement care pathways to optimize genetic counseling referral and testing in all young-onset colorectal cancer patients,” she said at the annual meeting of the American College of Gastroenterology.

The incidence of CRC diagnosed in persons younger than 50 years is increasing and has been projected to double by 2030, Dr. Syed noted.

In 2009, the Eastern Cooperative Oncology Group recommended that all patients with colorectal cancer be screened for the Lynch syndrome, and earlier this year the National Comprehensive Cancer Network issued a recommendation that patients with YOCRC undergo germline multigene panel testing (MGPT). MGPT has shown that as many as 30% of patients with YOCRC carry a germline pathogenic variant that predisposes them to CRC, regardless of family history, she said.

“We hypothesized that the rate of referral to genetic counseling in this population is low despite the high incidence of pathogenic germline variants, but the uptake of genetic counseling is high [when referred],” Dr. Syed said.
 

How often, and who needs it?

The investigators sought to determine the frequency of referral to genetic counseling and patient uptake of referrals to assess factors associated with referrals and with uptake, and to evaluate the results of genetic testing.

They reviewed records on all patients younger than 50 years seen at the Cleveland Clinic for CRC from 2010 through 2019, excluding those with appendiceal cancers, a family history of a hereditary cancer syndrome, or irritable bowel syndrome.

The information they extracted from electronic medical records included patient age, sex, family history of CRC, income, tumor stage, and the location and time period of CRC diagnosis.

They considered a genetic counseling referral to be either an order for counseling in the record; clinical documentation of a referral in an office visit with colorectal surgery, oncology, or gastroenterology specialists; or documentation of a completed visit with a genetic counselor.

They considered patient uptake of a counseling referral as either a completed visit to the counselor or documentation of genetic testing results.

The mean patient age at diagnosis was 44 years, with 57.3% of patients male, and 42.7% female. The large majority of patients (86.5%) were White. In all, 40.2% of patients had a family history of CRC.

As noted above, 62.1% of the 791 patients included in the study were referred for counseling, and 80.1% of those referred followed through with uptake. Of this group, nearly all (97.1%) completed genetic testing.

In univariate analysis, factors associated with referral included older patient age at diagnosis, which showed that patients approaching 50 were less likely to receive a referral (odds ratio, 0.904), year of diagnosis with patients diagnosed in the most recent period more likely to receive a referral (OR, 1.247), and family history of CRC (OR, 2.195).

In multivariate analysis, factors significantly associated with referral were age at diagnosis (OR, 0.89), family history of CRC (OR, 2.112), and year of diagnosis (for 2017-19 vs. 2010-13, OR, 5.361).

Among 377 patients who completed genetic testing, 21% were found to have a pathogenic variant, 23% had variants of unknown significance, and 56% had no variants detected. The most commonly detected pathogenic variants were the Lynch syndrome and adenomatous polyposis.
 

 

 

Educate patients and physicians

In an interview, Daniel J. Pambianco, MD, from Charlottesville (Va.) Gastroenterology Associates, who was not involved in the study, commented that patient perceptions about the consequences of genetic testing may be a barrier to either getting a referral for counseling or following through on one.

“Oftentimes patients will perceive anything with ‘genetic’ in it as if their genes are somehow being manipulated, and we need to do a better job at educating patients in that regard,” he said.

Physicians, both primary care practitioners and gastroenterologists, also need to fully appreciate the importance of genetic testing in this population, “because in essence there may be a 4%, 5%, or 6% risk of genetic syndromes that we’re missing and cannot pick up just from getting patients’ histories,” he said.

The investigators did not report a study funding source. Dr. Syed and Dr. Pambianco reported having no relevant financial disclosures.

EUS-guided RF ablation doubles survival for unresectable pancreatic cancer

Article Type

Wed, 10/26/2022 - 13:25

In a small proof-of-concept study, patients with small unresectable pancreatic cancers treated with endoscopic ultrasound–guided radiofrequency ablation (EUS-RFA) had a more than twofold improvement in overall survival compared with historical controls with a similar disease history, investigators in Thailand found.

In a weighted analysis, median weighted overall survival – the primary outcome – was 14 months among 11 patients who underwent EUS-RFA, compared with 6.1 months for 35 matched controls, translating into a hazard ratio for death with EUS-RFA of 0.38 (P = .016), reported Chawin Lopimpisuth, MD, from King Chulalongkorn Memorial Hospital in Bangkok, Thailand.

Median weighted progression-free survival (PFS) was longer among cases than controls, but did not differ significantly, at 6.1 months and 3.9 months, respectively.

“In patients with unresectable pancreatic ductal adenocarcinomas that are less than 4 cm, EUS-RFA alone or combined with chemotherapy resulted in significantly improved overall survival and tended to improve progression-free survival with minimal adverse events,” Dr. Lopimpisuth reported at the annual meeting of the American College of Gastroenterology.
 

Small but unresectable tumors

Endoscopically guided radiofrequency ablation of pancreatic ductal tumors has been shown to be both feasible and safe in previous studies, he said, prompting his group to explore whether EUS-RFA could help to control the primary tumor and improve survival outcomes.

They enrolled 11 patients with primary pancreatic ductal adenocarcinoma tumors less than 4 cm in diameter that were unresectable due to blood vessel involvement or distant metastasis, and used propensity-score matching to pair them with a total of 35 controls. Controls were matched by tumor size, staging, age-adjusted Charlson Comorbidity Index, chemotherapy regimen received, and interactions between CCI, regimen, and staging.

The results were weighted to assure that covariate distribution among patients treated with chemotherapy only equaled that of patients who underwent EUS-RFA.

Patients underwent EUS-RFA with a 19-gauge needle, with 50 watts of energy delivered with an impedance of 100 ohms. Those patients deemed able to tolerate chemotherapy received that as well.

After a minimum of 1 year of follow-up, the median weighted survival, as noted before, was 14 months for patients who received EUS-RFA, compared with 6.1 months for controls.

Adjusted survival probabilities at 6 and 12 months were 73% and 64%, respectively, for patients in the EUS-RFA group, compared with 69% and 17% for controls. Adjusted PFS rates at 6 and 12 months were 55% and 36% in the EUS-RFA group, compared with 28% and 4% in the control group.

The only adverse event of significance was mild abdominal pain, reported by 8.3% of total EUS-RFA procedures.
 

Promising but preliminary

In an interview with this news organization, ACG President Samir A. Shah, MD, from Brown University and Miriam Hospital in Providence, R.I., who was not involved in the study, commented that “we have limited options with these patients, so it’s really exciting to see an initial trend toward efficacy, and their survival improvement was significant by several months.”

Dr. Shah was a moderator of the presidential symposium where the data were presented.

Comoderator Brooks D. Cash, MD, from the University of Texas Health Science Center at Houston, said that the advantage of EUS-RFA is that it’s only minimally invasive and appears to offer a significant survival advantage for patients with few effective treatment options.

He cautioned, however, that “it’s a small study and needs to be replicated in a larger venue and different sites as well, but I think it looks very promising.”

The investigators did not report a funding source for the study. Dr. Lopimpisuth, Dr. Shah, and Dr. Cash all reported having no relevant financial relationships to disclose.

Pancreatic cancer screening appears safe, effective for high-risk patients

Article Type

Wed, 11/09/2022 - 13:47

Pancreatic cancer screening appears to be safe and effective for certain patients with high-risk indications due to genetic susceptibility, according to a prospective multicenter study presented at the annual meeting of the American College of Gastroenterology.

Screening in high-risk patients detected high-risk lesions in 0.8% of patients, which was lower than the typical range found in the literature, at 3%, said Andy Silva-Santisteban, MD, a research fellow at Beth Israel Deaconess Medical Center at Harvard Medical School in Boston.

Pancreatic cancer is the third leading cause of cancer death in the U.S., which is estimated to become the second leading cause by 2030. About 15%-20% of patients are candidates for surgical resection at the time of diagnosis, with survival rates below 10%.

“These statistics have led pancreatic cancer screening to be studied with the goal of detecting earlier stages of the disease to improve survival,” Dr. Silva-Santisteban said. “However, pancreatic cancer screening is not recommended for the general population.”

Pancreatic cancer screening is recommended for patients with increased risk due to genetic susceptibility, yet recent studies have found that screening studies face limitations from factors like small sample sizes, single-center focus, retrospective nature, nonconsecutive accrual of patients, varied inclusion criteria, and use of nonstandardized screening protocols.

To overcome these limitations, Dr. Silva-Santisteban and colleagues conducted a prospective multicenter study of pancreatic cancer screening in consecutive high-risk patients at five centers in the United States between 2020 and 2022, also called the Pancreas Scan Study. Dr. Silva-Santisteban presented results from the first round of enrollment, which was awarded the Outstanding Research Award in the Biliary/Pancreas Category for Trainee.

The research team evaluated the yield (low-, moderate-, and high-risk pancreatic pathology), safety, and outcomes of screening. Low-risk pancreas pathology was categorized as fatty pancreas and chronic pancreatitis-like changes. Intermediate-risk was categorized as branch duct–intraductal papillary mucinous neoplasm or neuroendocrine tumor under 2 cm. High-risk was categorized as main duct–intraductal papillary mucinous neoplasm (MD-IPMN), pancreatic intraepithelial neoplasia grade III (PanIN-III)/dysplasia, neuroendocrine tumor over 2 cm, or pancreatic cancer.

Patients were included if they were 18 years or older and had at least one of the following: BRCA1, BRCA2, or PALB2 plus a family history of pancreatic cancer; Lynch syndrome plus a family history of pancreatic cancer; Peutz-Jeghers syndrome; familial atypical multiple mole melanoma (FAMMM); ataxia telangiectasia mutated plus family history of pancreatic cancer; hereditary pancreatitis; or familial pancreatic cancer (FPC) syndrome.

 

 


Screening was performed annually with either endoscopic ultrasound (EUS) or magnetic resonance cholangiopancreatography (MRCP). Fasting blood sugar was recorded annually to screen for new-onset diabetes.

Among 252 patients, 208 underwent EUS and 44 underwent MRCP. At the time of enrollment, 38.5% underwent their first screening, and 61.5% had a prior screening. The average age was 60, 69% were women, and 79% were White.

The most common indication was a BRCA1 or BRCA2 pathogenic variant in 93 patients (or 36.5%), followed by FPC syndrome in 80 patients (or 31.7%).

Low-risk pancreas pathology was noted in 23.4% of patients, with 17.5% having chronic pancreatitis-like changes. Intermediate risk was found in 31.7%, with nearly all detected as branch-duct IPMNs without worrisome features, Dr. Silva-Santisteban said.

Two patients (.8%) fell into the high-risk category with pancreatic adenocarcinoma. Both were positive for BRCA2 mutation and family history of pancreatic cancer.

In the first patient, who was compliant with screening, EUS showed a 3-cm adenocarcinoma (T2N1M0 stage IIB). The patient underwent neoadjuvant chemotherapy, followed by total pancreatectomy, and is currently in cancer remission. No complications from surgery were noted.

In the second patient, who was not compliant with screening and was lost to follow-up for 6 years, EUS showed a 2.5-cm adenocarcinoma and four metastatic lesions in the liver (T2N1M1 stage IV). The patient underwent palliative chemotherapy.

EUS was more likely to identify chronic pancreatitis-like changes, but MRCP was more likely to identify BD-IPMN. The two patients with pancreatic adenocarcinoma were identified with EUS. However, there wasn’t a significant difference between EUS and MRCP in identifying high-risk lesions.

In patients undergoing screening, new-onset prediabetes was noted in 18.2%, and new-onset diabetes was noted in 1.7%. However, there was no association between abnormal blood sugar and pancreas pathology.

Twelve patients (4.8%) underwent further pancreatic evaluation because of screening findings. None of the patients underwent low-yield pancreatic surgery, which was lower than reported in the literature, at 2.8%. Overall, there were no complications as a direct result of screening with EUS or MRI.

“Patients should be carefully counseled regarding benefits and harms from pancreatic cancer screening,” Dr. Silva-Santisteban said. “When feasible, such screening should be performed within the confines of a research study so more precise estimates of screening outcomes can be determined.”

The study funding was not disclosed. One author reported a consultant relationship with Pentax Medical, and the other authors indicated no relevant financial relationships.

Pancreatic cancer screening is recommended for patients with increased risk due to genetic susceptibility, yet recent studies have found that screening studies face limitations from factors like small sample sizes, single-center focus, retrospective nature, nonconsecutive accrual of patients, varied inclusion criteria, and use of nonstandardized screening protocols.

To overcome these limitations, Dr. Silva-Santisteban and colleagues conducted a prospective multicenter study of pancreatic cancer screening in consecutive high-risk patients at five centers in the United States between 2020 and 2022, also called the Pancreas Scan Study. Dr. Silva-Santisteban presented results from the first round of enrollment, which was awarded the Outstanding Research Award in the Biliary/Pancreas Category for Trainee.

The research team evaluated the yield (low-, moderate-, and high-risk pancreatic pathology), safety, and outcomes of screening. Low-risk pancreas pathology was categorized as fatty pancreas and chronic pancreatitis-like changes. Intermediate-risk was categorized as branch duct–intraductal papillary mucinous neoplasm or neuroendocrine tumor under 2 cm. High-risk was categorized as main duct–intraductal papillary mucinous neoplasm (MD-IPMN), pancreatic intraepithelial neoplasia grade III (PanIN-III)/dysplasia, neuroendocrine tumor over 2 cm, or pancreatic cancer.

Patients were included if they were 18 years or older and had at least one of the following: BRCA1, BRCA2, or PALB2 plus a family history of pancreatic cancer; Lynch syndrome plus a family history of pancreatic cancer; Peutz-Jeghers syndrome; familial atypical multiple mole melanoma (FAMMM); ataxia telangiectasia mutated plus family history of pancreatic cancer; hereditary pancreatitis; or familial pancreatic cancer (FPC) syndrome.

 

 


Screening was performed annually with either endoscopic ultrasound (EUS) or magnetic resonance cholangiopancreatography (MRCP). Fasting blood sugar was recorded annually to screen for new-onset diabetes.

Among 252 patients, 208 underwent EUS and 44 underwent MRCP. At the time of enrollment, 38.5% underwent their first screening, and 61.5% had a prior screening. The average age was 60, 69% were women, and 79% were White.

The most common indication was a BRCA1 or BRCA2 pathogenic variant in 93 patients (or 36.5%), followed by FPC syndrome in 80 patients (or 31.7%).

Low-risk pancreas pathology was noted in 23.4% of patients, with 17.5% having chronic pancreatitis-like changes. Intermediate risk was found in 31.7%, with nearly all detected as branch-duct IPMNs without worrisome features, Dr. Silva-Santisteban said.

Two patients (.8%) fell into the high-risk category with pancreatic adenocarcinoma. Both were positive for BRCA2 mutation and family history of pancreatic cancer.

In the first patient, who was compliant with screening, EUS showed a 3-cm adenocarcinoma (T2N1M0 stage IIB). The patient underwent neoadjuvant chemotherapy, followed by total pancreatectomy, and is currently in cancer remission. No complications from surgery were noted.

In the second patient, who was not compliant with screening and was lost to follow-up for 6 years, EUS showed a 2.5-cm adenocarcinoma and four metastatic lesions in the liver (T2N1M1 stage IV). The patient underwent palliative chemotherapy.

EUS was more likely to identify chronic pancreatitis-like changes, but MRCP was more likely to identify BD-IPMN. The two patients with pancreatic adenocarcinoma were identified with EUS. However, there wasn’t a significant difference between EUS and MRCP in identifying high-risk lesions.

In patients undergoing screening, new-onset prediabetes was noted in 18.2%, and new-onset diabetes was noted in 1.7%. However, there was no association between abnormal blood sugar and pancreas pathology.

Twelve patients (4.8%) underwent further pancreatic evaluation because of screening findings. None of the patients underwent low-yield pancreatic surgery, which was lower than reported in the literature, at 2.8%. Overall, there were no complications as a direct result of screening with EUS or MRI.

“Patients should be carefully counseled regarding benefits and harms from pancreatic cancer screening,” Dr. Silva-Santisteban said. “When feasible, such screening should be performed within the confines of a research study so more precise estimates of screening outcomes can be determined.”

The study funding was not disclosed. One author reported a consultant relationship with Pentax Medical, and the other authors indicated no relevant financial relationships.

Pancreatic cancer screening appears to be safe and effective for certain patients with high-risk indications due to genetic susceptibility, according to a prospective multicenter study presented at the annual meeting of the American College of Gastroenterology.

Screening in high-risk patients detected high-risk lesions in 0.8% of patients, which was lower than the typical range found in the literature, at 3%, said Andy Silva-Santisteban, MD, a research fellow at Beth Israel Deaconess Medical Center at Harvard Medical School in Boston.
