No survival benefit of RAI seen in early-stage thyroid cancer
CORONADO, CALIF. – In a large cohort of patients with differentiated thyroid cancer, the use of radioactive iodine was associated with improved disease-specific survival in those with advanced disease but not in those with papillary thyroid microcarcinoma.
“Everything in medicine is a risk-benefit balance,” lead author Dr. Ryan K. Orosco said in an interview in advance of the annual meeting of the American Thyroid Association, where the work was presented. “Any two patients that receive radioactive iodine (RAI) for differentiated thyroid cancer are likely to have different survival benefit from that therapy. This study provides a quantitative comparison of the impact of RAI in various patient subgroups.”
In one of the largest studies of its kind, Dr. Orosco of the division of head and neck surgery at the University of California, San Diego, and his associates identified 85,740 patients with differentiated thyroid carcinoma from the Surveillance, Epidemiology, and End Results database from 1973 through 2009. They used multivariate analyses to explore the association between RAI and cancer-specific survival in 149 population subgroups, controlling for age, decade of diagnosis, race, gender, tumor type, nodal involvement, metastasis stage, and RAI therapy.
More than three-quarters of the patients (78%) were female, 68% were white, their mean age at diagnosis was 46 years, and the median follow-up time was 85 months. The researchers found that nearly half of patients (43%) received RAI. By American Joint Committee on Cancer stage, RAI was used in 55% of stage I patients, 41% of stage II patients, 94% of stage III patients, and 85% of stage IV patients. In addition, 42% of patients with T1a disease and 88% of those with T4 disease received RAI.
Use of RAI was positively associated with survival in the overall cohort (hazard ratio 1.3; P = .002), while statistically significant HRs for RAI were observed in 49 population subgroups. In patients with metastatic disease, use of RAI was associated with a decreased risk for disease-specific mortality (HR range of 2.28-3.82). Protective effects of RAI were also observed in patients with regional metastases (HR 1.4-1.9), those with T3-positive tumors (HR 1.36-1.39), those with T4 tumors (HR 1.85), and in those with stage IV disease (HR 1.47-1.73).
Dr. Orosco and his associates observed a negative effect of RAI in patients with macropapillary carcinoma. Specifically, those with T1a disease had an increased likelihood of thyroid cancer–specific mortality (HR .13; P less than .001), while similar associations were seen in multiple subgroups of patients with T1a disease (HR 0.04-0.25). No statistically significant effects of RAI were observed in patients with T1b or T2 tumors.
“RAI appears to offer the best survival impact in patients with advanced differentiated thyroid carcinoma,” Dr. Orosco said. “Its use in early-stage patients should be carefully considered.”
In their abstract, the researchers noted that the findings “might help clinicians personalize RAI therapy to specific differentiated thyroid cancer populations – offering treatment in patients most likely to benefit, and sparing others unnecessary costs and potential side effects.”
Dr. Orosco acknowledged certain limitations of the study, including the fact that the SEER database does not contain details about each patient’s surgery, the dose of RAI used, other comorbidities, or data on cancer recurrence. “This study does not attempt to explore the reasons behind the apparent survival disadvantage seen in patients with T1a disease,” he said. “We don’t know exactly why early-stage patients have an increased risk of disease-specific mortality when RAI is used. Additional work is needed to explore this further.”
Dr. Orosco reported having no financial disclosures.

E-cigarettes don’t help cancer patients quit smoking
Though e-cigarette use increased among smokers diagnosed with cancer, it did not lead to greater success with tobacco cessation, according to a study among cancer patients referred to a tobacco quit program.
The prospective cohort study of 1,074 cancer patients found the prevalence of e-cigarette use increased from 10.6% of participants enrolled in 2012 to 38.5% of patients in 2013, with 92% of e-cigarette users reporting dual use with traditional cigarettes.
At study entry, e-cigarette users were more nicotine dependent than were nonusers, had more prior quit attempts, and were more likely to be diagnosed with thoracic and head or neck cancers. Smoking cessation outcomes were collected from 414 patients, and after adjustment for nicotine dependence, number of past quit attempts, and cancer diagnosis, e-cigarette users were twice as likely to still be smoking at follow-up (odds ratio, 2.0; 95% confidence interval, 1.2-3.3; P less than .01), Sarah P. Borderud and her colleagues reported online Sept. 22 in Cancer [doi:10.1002/cncr.28811].
“Although we speculate that patients may be drawn to e-cigarette use for harm reduction, the findings of the current study provide no evidence to support oncologists recommending e-cigarette use among patients with cancer who are advised to quit smoking,” wrote Ms. Borderud, an epidemiologist at Memorial Sloan-Kettering Cancer Center, N.Y., and her colleagues.
No conflicts of interest were declared.

Systems Automation for Cancer Surveillance: A Useful Tool for Tracking the Care of Head and Neck Cancer Patients in the Ear, Nose, and Throat Clinic
Purpose: About 400,000 new cases of Head and Neck Cancer (HNC) are diagnosed and reported each year. HNC patients require frequent follow-up care and additional interventions due to the potential for disease recurrence and second primaries. A robust and automated HNC identification and surveillance program can aid in case identification and can track appointments and required care, using the guidelines of the National Comprehensive Cancer Network (NCCN). An automated tool would provide for optimal treatment interventions while preventing any patients from being inadvertently lost to follow-up, enhancing veteran centered care.
Methods: The ear, nose, and throat (ENT) Cancer Tracking System (CTS) queries the VA Corporate Data Warehouse each night to identify all patients recently diagnosed with a HNC. All patients residing in the Albuquerque, New Mexico, and Big Spring, Texas, catchment areas are included in the capture pool. Cases are identified by examining outpatient visits and inpatient discharge diagnosis International Classification of Diseases (ICD) codes, surgical pathology Systematized Nomenclature of Medicine—Clinical Terms (SNOMED codes), and VistA problem list diagnoses. Patients identified as having cancer are presented, using an interactive report hosted on a secure SharePoint site. Newly identified patients are automatically assigned to “active” management status, minimizing the risk of missing a new patient. The coordinator can toggle a patient’s status between “inactive” and “active” at any time, but can never delete a patient from the CTS. Inactive patients with a new cancer diagnosis are automatically toggled to active status. The CTS report tracks and presents a number of pertinent medical indicators, including patient identifiers and residence location, most recent diagnosis date, days since last diagnosis, diagnosis ICD code, date captured on the CTS, most recent ear, nose, and throat (ENT) visit, most recent ENT appointment, days since last visit, date of last thyroid-stimulating hormone (TSH) test, and date of last PET scan. Cancellations, no-shows, and patients overdue for TSH testing are highlighted.
Results: Baseline data obtained in 2012 prior to the activation of the CTS revealed that about 31.1% of diagnosed HNC patients in the ENT clinic experienced delays in care or were lost to follow-up care through cancellations, no shows, and nonrescheduled appointments. A dedicated cancer care coordinator (CCC) was assigned to the ENT clinic to record, monitor, and track HNC patients manually using an Excel spreadsheet. Although cancer surveillance reports proved that launching a cancer surveillance program prevented patients with cancer from being lost to follow-up care, the manual tracking system was time consuming and labor intensive. The automated CTS has optimized cancer surveillance by providing the CCC with immediate identification of new HNC diagnoses, appointment tracking, alerts for HNC patients that have not been scheduled, alerts of overdue required lab tests, tracking of completed PET CT imaging, and improved timeliness in obtaining quality improvement data; all were accomplished without the CCC manually tracking anything.
Conclusions: During the first 4 months of operation (February to May 2014), 14 new HNC patients were identified automatically—patients that manual tracking might have missed or incurred delays in care. The CTS has proved to be a vital tool to the CCC and will continue to assist in the identification of new HNC patients, provide access to patient information on follow-up care, and improve access to recommended diagnostic procedures from NCCN guidelines. Other benefits of an electronic tracking system are optimized time, improved workflows, and improvements to patient safety by providing timely access to care and treatment.

Effects of Feeding Tube Placement on Weight and Treatment Breaks in Patients With Locally Advanced Head and Neck Cancer Who Undergo Definitive Radiotherapy
Purpose: To evaluate the effects of feeding tube placement on patient weight and length of treatment breaks during definitive radiotherapy with at least 50 Gy to the bilateral necks of patients with head and neck (H&N) cancer.
Methods: Thirty-five H&N cancer patients underwent definitive radiotherapy at the Radiation Oncology Department at Michael E. DeBakey VA Medical Center from July 23, 2012 to April 25, 2013. Twenty-three patients received doses of ≥ 50 Gy to bilateral necks, and constituted the study group. The remaining 12 patients did not receive ≥ 50 Gy and were excluded from the study. Among the 23 patients, 11 underwent feeding tube placement (group 1). Group 2 consisted of 12 patients without feeding tubes. All patients with feeding tube placement had concurrent chemotherapy. Some patients in group 2 received radiation treatment only.
Results: Twenty-two patients had weight loss, 1 patient gained 6.9 lb during the course of treatment. The median weight loss for group 1 was 17.8 lb (ranging from 4.4 to 34.4 lb), compared with 18.6 lb in patients in group 2. Those in group 2 who only received radiation therapy had the least median weight loss (5.4 lb). The average treatment break was 3.3 days for patients in group 1, 3.7 days for those in group 2 with concurrent chemo-radiotherapy (chemoRT), and 3.2 days for group 2 subjects receiving radiation therapy only.
Conclusions: In H&N cancer patients, feeding tube placement did not minimize weight loss and did not reduce average treatment breaks in those given concurrent chemoRT. An interesting additional finding of the study was that chemotherapy seems to have greater impact on a patient’s ability to tolerate radiation therapy. Our findings in this small, retrospective study, though suggestive, are insufficient to draw any definitive conclusions about the effectiveness of prophylactic feeding tube placement in the target patient population. Published studies on this subject are contradictory. Treatment decisions should be based on physician expertise and individualized to clinical needs of patients.

Comparison of Low-Dose Platinum vs High-Dose Platinum vs Cetuximab and Intensity-Modulated Radiation Therapy in Advanced Head and Neck Cancers
Purpose: High-dose cisplatin is standard in head and neck cancers. Recently, weekly low-dose platinum alone or with cetuximab has been used. All patients received 70 Gy standard fraction intensity-modulated radiation therapy. We are comparing the former used at the VAMC with the latter regimens used in the department of Oncology at the University of Mississippi. We will present the toxicity, response, patterns of failure, and survival by the use of the different types of chemotherapy.
Purpose: High-dose cisplatin is standard in head and neck cancers. Recently, weekly low-dose platinum alone or with cetuximab has been used. All patients received 70 Gy standard fraction intensity-modulated radiation therapy. We are comparing the former used at the VAMC with the latter regimens used in the department of Oncology at the University of Mississippi. We will present the toxicity, response, patterns of failure, and survival by the use of the different types of chemotherapy.

Cisplatin Is Associated With Prolonged Progression-Free Survival Compared With Cetuximab Among Veteran Patients With Stage 3 And 4 Head and Neck Cancer
Purpose: Concurrent cisplatin and radiation is currently the preferred therapy for stage 3 and 4 head and neck cancer. However, patient tolerability is poor. Concurrent cetuximab and radiation, on the other hand, is well tolerated. However, head-to-head comparative studies with cisplatin are lacking. The purpose of this study was to compare the efficacy, tolerability, and total health care costs of cisplatin- and cetuximab-based regimens among veteran patients with head and neck cancer.
Methods and Materials: We conducted a retrospective study of patients with stage 3 and 4 head and neck cancer at the VA Pittsburgh Healthcare System from 2009-2013. Patients were included if they had biopsy-proven disease treated with cisplatin or cetuximab (both with concurrent radiation). Patients receiving adjuvant chemoradiation, those with non-squamous cell carcinoma, or carcinoma of the nasopharynx were excluded. Baseline characteristics were compared by chi-square or Fisher’s exact tests for categorical variables and by Mann-Whitney for continuous variables. The primary outcome was average chemotherapy dose intensity. Secondary outcomes included progression-free survival (PFS) and overall survival (OS) , which were compared by Kaplan-Meier and the log-rank test. Results: Fifty-two patients were included; 30 received cisplatin and 22 cetuximab. Patients who received cetuximab were older (median age, 66 vs 63; P = .04) and more likely to have diabetes (36% vs 7%; P = .01) and a CrCl 2 (9 vs 7; P = .33) were comparable between both groups. Patients were followed for a median of 29 months (range 0.4-64). Average chemotherapy dose intensity was lower for cisplatin (88% vs 96%; P = .03). Progression-free survival was longer among cisplatin patients (median 21 months, range 0-57) compared with that of cetuximab (median 17 months, range 1-52; P = 0.03) and did not vary among patients who did or did not receive 100% chemotherapy dose-intensity cisplatin (median 18 vs 27 months; P = .16). There was no difference in OS (31 vs 18 months, P = .19). Neutropenia (47% vs 0%; P ≤ .0001), dehydration (33% vs 0%; P = .003), nausea/vomiting (30% vs 0%; P = .07), and hypotension (23% vs 0%; P = .02) were higher among cisplatin patients. Rash was more common with cetuximab (64% vs 7%; P ≤ .0001). The average health care costs were $3,495 and $27,148 for cisplatin and cetuximab, respectively.
Conclusions: Among veterans with stage 3 or 4 head and neck cancer, treatment with cisplatin-based chemotherapy is associated with PFS compared with cetuximab-based regimens despite cisplatin patients receiving only 88% of chemotherapy. Patients who received cetuximab experienced fewer adverse effects. However, total health care costs were significantly higher. Our data suggest that cisplatin should remain the front-line therapy for stage 3 and 4 head and neck cancer. Cetuximab is best reserved for patients who are intolerant of or have a contraindication to cisplatin.

Incorporation of Palliative Care With Chemotherapy and Radiation in Patients Treated for Head and Neck Cancer
Purpose: Recent studies have suggested that incorporation of palliative care concomitantly with therapy for metastatic cancer may be beneficial. The American Society of Clinical Oncology has published a provisional clinical opinion recommending incorporation of palliative care alongside chemotherapy in patients with metastatic cancer or a high symptom burden from cancer. In this project, we evaluate the feasibility of incorporation of palliative care in patients with head and neck (H&N) cancer treated with concurrent chemotherapy and radiation.
Methods: The primary goal of this quality improvement project is to assess the feasibility of participation in a palliative care program for patients with H&N cancer undergoing treatment. Patients are recommended for palliative care consultation if they have squamous cell carcinoma of the head and neck and are treated with concurrent chemotherapy and radiation (definitive or adjuvant therapy). Patients are offered palliative care consultation in their first week of treatment. They are approached in person to discuss goals and potential benefits of concomitant palliative care and chemotherapy/radiation. All patients are provided with informational material to review. If interested in palliative care, the participant is asked to fill out 5 non-mandatory questionnaires. These include the FACT-H&N, FACIT-Sp-12, PHQ-9, EAT-10, and HADS. Patients are seen by the palliative care service at 6, 12, 26, and 52 weeks after starting chemotherapy/radiation, and patients are asked to fill out the questionnaires at those time points as well. In addition, data on several potential quality elements (weight, use of enteral nutrition, laboratory values, site of disease, p16ink4a status, etc) are collected for comparison with a retrospective cohort.
Results: Retrospective data from the charts of 51 patients have been abstracted and analyzed for comparison with the prospective quality improvement cohort. The median age was 63 (range 48 to 87). Forty-four patients were either stage IVa or IVb. The location of primary tumors included the oropharynx (59%), oral cavity (11.8%), hypopharynx (9.8%), larynx (9.8%), and the nasopharnyx (7.8%). Forty-four of the 51 patients had a percutaneous endoscopic gastrostomy tube (for potential enteral nutrition) placed either prophylactically (before or within the first week of treatment, 19 patients) or reactively (after the first week of treatment, 25 patients). In the prospective cohort, 14 patients have thus far been offered palliative care consultation. Six patients agreed to palliative care consultation and 8 declined. The median age was 62, and all patients were male. Data collection and analysis are ongoing.
Conclusions: The results of this project may be able to guide incorporation of routine palliative care with the treatment of patients with (H&N) cancer. Barriers to enrolling in palliative care concomitantly with chemotherapy and radiation should be considered to aid incorporation of early palliative care for patients with H&N cancer.

Incidence of Second Primary Malignancies in Patients Treated for Thyroid Cancer: A Review of 51 Cases
Purpose: The incidence of the second primary cancer after treatment with radioactive iodine (RAI) is a concern for patients and clinicians. Our objective was to examine the changes that have occurred over a 20-year period in a single institution, by comparing the lifetime observed incidence of the second primary cancer vs those patients with the incidence after the treatment with RAI.
Method: We reviewed all thyroid cancer cases (n = 51) between 1991 and 2010 in the VA New Jersey cancer registry. Patients were distributed into 4 groups consisting of 5-year intervals. These groups were based on accession year and then segregated again into groups that received radioactive iodine and groups that did not. Then, we reviewed the incidence of multiple primaries during the life of the patient and the incidence of a second primary after the diagnoses of thyroid cancer. The incidence of second primary malignancy and age distribution of these groups over the study period was also compared.
Results: An increase in the number of cases diagnosed over the last 20 years was noted. There were a total of 12 cases in the first 10 years compared with 39 cases in the last 10 years. During this period, the total number of all cancer cases accessioned by the registry per year remained stable and constant. However, the increases were significant in the last 5 years; comprising more than half of all cases diagnosed in this 20-year period. There was an observed difference in the average age at diagnosis with the mean age for the first 10 years being 56 years in comparison to the past 10 years, which was 61 years. Also, patients who received radioactive iodine were consistently younger than the group who did not receive RAI. The lifetime incidence of multiple primaries was about 50% in the entire group. The incidence remains similar in each period examined and in all the groups. However, there is an observed difference in the incidence of second primary in the RAI group after treatment compared with those who did not received RAI.
Conclusions: There was an increase in the incidence of thyroid cancer diagnosed over the 20-year period, and the overall incidence of multiple primaries during this time span remained consistent. However, the observed incidence of the second primary after the diagnoses of thyroid cancer was higher in the group who received RAI treatment.

Hold the central lymph node dissection for small parathyroid tumors?
BOSTON – Central lymph node dissection may not be necessary in patients with small parathyroid carcinomas, results of a data review suggest.
Among 405 U.S. patients treated in the last two decades for parathyroid carcinomas, disease-specific mortality and degree of local tumor invasion did not differ depending on nodal involvement, reported Dr. Kun-Tai Hsu, an associate research specialist in the surgery department at the University of Wisconsin, Madison.
Patients with tumors greater than 3 cm in diameter and distal metastasis had worse disease-specific mortality, and larger tumors were significantly more likely to be associated with positive lymph nodes, Dr. Hsu reported at the annual meeting of the American Association of Endocrine Surgeons.
The findings raise the question of whether central lymph node dissection is necessary for all patients with parathyroid carcinomas, but "our conclusions may not translate directly into definitive recommendations," said Dr. Hsu, who advised further study of whether patients with tumors larger than 3 cm may benefit from lymph node dissection.
Parathyroid carcinomas are rare cancers, accounting for 0.005% of all malignancies and less than 1% of primary hyperparathyroidism. The current standard of therapy is en bloc removal of the parathyroid tumor and ipsilateral lobectomy, isthmusectomy, and central lymph node dissection.
Over at least 5 years of follow-up, neither tumor size nor lymph node status was significantly predictive of outcomes in an earlier retrospective study of 286 patients treated in the 1980s and 1990s.
In addition, a 2006 study using data from the Surveillance, Epidemiology and End Results (SEER) database showed a significant increase in the incidence of this malignancy from 1988 through 2003. The authors identified younger age, female sex, more recent diagnosis, and absence of distant metastases as favorable prognostic factors (Cancer 2007;109:1736-41).
What the previous studies could not answer, however, was whether lymph node metastases were associated with worse disease-specific mortality and whether central lymph node dissection might improve survival in patients with parathyroid carcinomas, Dr. Hsu noted.
He and his colleagues queried SEER for disease-specific survival outcomes and lymph-node status of all patients treated in the United States for parathyroid carcinomas from 1988 through 2010.
They identified 212 female and 193 male patients. Among all patients, 112 (27.7%) had tumors 3 cm or greater, and 12 (3%) had positive lymph nodes. Median follow-up was 68 months.
In a multivariate analysis of disease-specific mortality predictors adjusted for sex and age only, tumors 3 cm or greater and the presence of metastasis were predictive of worse survival, with respective hazard ratios of 5.35 (P = .01) and 45.1 (P less than .01).
Similarly, an analysis adjusted for sex, age, and year of diagnosis showed that tumor size but not age or sex significantly predicted lymph node metastasis (HR, 19.48; P = .02)
A comparison of outcomes between patients with and without lymph node examinations found no differences in disease-specific mortality by sex, age, year of diagnosis, tumor size, local invasion, or metastasis. Significant predictors of disease-specific mortality in this analysis included surgery type (parathyroidectomy, en bloc excision, or debulking), the use of radiation, and white race.
Dr. Hsu noted that the study was limited by its retrospective design, lack of information on other significant clinical variables, lack of detailed follow-up data, and the possibility of misclassification or miscoding of cases.
He acknowledged that uncertainty about the diagnosis is a drawback to SEER-based studies, but that given the rarity of the disease, SEER data are the most reliable source of information.
The study was supported by the Wisconsin Surgical Outcomes Research Program. Dr. Hsu reported having no relevant disclosures. Study coauthor Dr. Rebecca Sippel is a member of this publication’s editorial advisory board.
The accuracy of diagnoses is questionable among patients in this study. A diagnosis of parathyroid carcinoma is based on several factors, including the presence of local invasion, lymph node metastases, or systemic metastases, but only a relatively small percentage of patients in the study had local invasion, suggesting that the diagnosis was based on examination of microscopic tumor features in the absence of local invasion.
An alternative explanation for the lack of a disease-specific mortality difference by lymph node status is that you may have included patients who really don’t have parathyroid cancer.

Similarly, an analysis adjusted for sex, age, and year of diagnosis showed that tumor size but not age or sex significantly predicted lymph node metastasis (HR, 19.48; P = .02)
A comparison of outcomes between patients with and without lymph node examinations found no differences in disease-specific mortality by sex, age, year of diagnosis, tumor size, local invasion, or metastasis. Significant predictors of disease-specific mortality in this analysis included surgery type (parathyroidectomy, en bloc excision, or debulking), the use of radiation, and white race.
Dr. Hsu noted that the study was limited by its retrospective design, lack of information on other significant clinical variables, lack of detailed follow-up data, and the possibility of misclassification or miscoding of cases.
He acknowledged that uncertainty about the diagnosis is a drawback to SEER-based studies, but that given the rarity of the disease, SEER data are the most reliable source of information.

BOSTON – Central lymph node dissection may not be necessary in patients with small parathyroid carcinomas, results of a data review suggest.
Among 405 U.S. patients treated in the last two decades for parathyroid carcinomas, disease-specific mortality and degree of local tumor invasion did not differ depending on nodal involvement, reported Dr. Kun-Tai Hsu, an associate research specialist in the surgery department at the University of Wisconsin, Madison.
Patients with tumors greater than 3 cm in diameter and distal metastasis had worse disease-specific mortality, and larger tumors were significantly more likely to be associated with positive lymph nodes, Dr. Hsu reported at the annual meeting of the American Association of Endocrine Surgeons.
The findings raise the question of whether central lymph node dissection is necessary for all patients with parathyroid carcinomas, but "our conclusions may not translate directly into definitive recommendations," said Dr. Hsu, who advised further study of whether patients with tumors larger than 3 cm may benefit from lymph node dissection.
Parathyroid carcinomas are rare cancers, accounting for 0.005% of all malignancies and less than 1% of primary hyperparathyroidism. The current standard of therapy is en bloc removal of the parathyroid tumor and ipsilateral lobectomy, isthmusectomy, and central lymph node dissection.
Over at least 5 years of follow-up, neither tumor size nor lymph node status was significantly predictive of outcomes in an earlier retrospective study of 286 patients treated in the 1980s and 1990s.
In addition, a 2006 study using data from the Surveillance, Epidemiology and End Results (SEER) database showed a significant increase in the incidence of this malignancy from 1988 through 2003. The authors identified younger age, female sex, more recent diagnosis, and absence of distant metastases as favorable prognostic factors (Cancer 2007;109:1736-41).
What the previous studies could not answer, however, was whether lymph node metastases were associated with worse disease-specific mortality and whether central lymph node dissection might improve survival in patients with parathyroid carcinomas, Dr. Hsu noted.
He and his colleagues queried SEER for disease-specific survival outcomes and lymph-node status of all patients treated in the United States for parathyroid carcinomas from 1988 through 2010.
They identified 212 female and 193 male patients. Among all patients, 112 (27.7%) had tumors 3 cm or greater, and 12 (3%) had positive lymph nodes. Median follow-up was 68 months.
