Management of Recurrent Well-Differentiated Thyroid Carcinoma in the Neck: A Comprehensive Review.

Surgery has been historically the preferred primary treatment for patients with well-differentiated thyroid carcinoma and for selected locoregional recurrences. Adjuvant therapy with radioactive iodine is typically recommended for patients with an intermediate to high risk of recurrence. Despite these treatments, locally advanced disease and locoregional relapses are not infrequent. These patients have a prolonged overall survival that may result in long periods of active disease and the possibility of requiring subsequent treatments. Recently, many new options have emerged as salvage therapies. This review offers a comprehensive discussion and considerations regarding surgery, active surveillance, radioactive iodine therapy, ultrasonography-guided percutaneous ablation, external beam radiotherapy, and systemic therapy for well-differentiated thyroid cancer based on relevant publications and current reference guidelines. We feel that the surgical member of the thyroid cancer management team is empowered by being aware and facile with all management options.

Well-Differentiated Thyroid Cancer: Who Should Get Postoperative Radiation?

BACKGROUND: The mainstay of treatment of well-differentiated thyroid cancer (WDTC) is surgery followed by adjuvant radioactive iodine therapy. Postoperative radiation therapy (PORT) is rarely used. OBJECTIVE: The aim of our study was to report our experience of patients with WDTC who were selected to receive PORT. MATERIALS AND METHODS: After Institutional Review Board approval, patients who received PORT were identified from a departmental database of 6259 patients with WDTC treated with primary surgery from 1986 to 2015. We carried out propensity matching to compare outcomes with a cohort of patients who did not receive PORT. The main outcome of interest was central neck recurrence-free probability (CNRFP), while secondary outcomes were lateral neck recurrence-free probability (LNRFP), disease-specific survival (DSS), and overall survival (OS). RESULTS: From 6259 patients, 32 (0.5%) patients with a median age of 65.2 years received PORT. Tall-cell variant papillary thyroid carcinoma was the most common pathology (45%). Patients who received PORT had no difference in CNRFP compared with patients treated without PORT (10-year CNRFP 88% vs. 73%; p = 0.18). Furthermore, patients who received PORT had superior LNRFP (10-year LNRFP 100% vs. 62%; p = 0.001) compared with the no-PORT cohort. Despite this, patients who received PORT had similar DSS (71% PORT vs. 75% no-PORT) and OS (65% PORT vs. 58% no-PORT group) as the no-PORT cohort. CONCLUSIONS: Our data show that select patients who received PORT had improved locoregional recurrence-free probability; however, this did not translate into improved DSS and OS. At our institution, we recommend the use of PORT only in highly selected patients with locally advanced primary tumors who are deemed to have a high risk of central neck recurrence for which salvage surgery would result in unacceptable risk to the airway.

Outcomes in surgical management of sinonasal malignancy-A single comprehensive cancer center experience.

BACKGROUND: Sinonasal malignancies are a complex and diverse group of tumors. Over the past five decades, treatment advances have changed the management paradigms for these tumors. Our aim was to analyze the outcomes of patients from a comprehensive cancer center. MATERIALS AND METHODS: We retrospectively assessed 400 patients with sinonasal malignancies treated with surgery at our center between 1973 and 2015. Multiple variables were reviewed to assess the influence on 5-year outcomes. RESULTS: The median age was 56 years (IQR 46.8-68). Two hundred and fifty-nine (65%) were males and 141 (35%) were females. Overall survival (OS) and disease-specific survival (DSS) improved in the last analyzed decade. Orbital invasion, advanced pT-classification and pN-classification, and melanoma histology were associated with poorer outcomes. CONCLUSION: Treatment outcomes for patients with sinonasal malignancy have improved over time. This is likely multifactorial with advances in surgical technique, adjuvant treatment, and patient selection. pT-classification, pN-classification, orbital invasion, and histology are predictive of survival.

Selinexor for the treatment of multiple myeloma.

Introduction: Despite unprecedented advances in the treatment of multiple myeloma (MM), almost all patients develop a disease that is resistant to the five most commonly used and active anti-MM agents. The prognosis for this patient population is particularly poor resulting in an unmet need for additional therapeutic options. Exportin-1 (XPO-1) is a major nuclear export protein of macromolecular cargo frequently overexpressed in MM. Selinexor is a first-in-class, oral Selective-Inhibitor-of-Nuclear-Export (SINE) compound that impedes XPO-1. Based on results of the STORM-trial, selinexor in combination with dexamethasone was granted accelerated FDA approval for patients with penta-refractory MM in July 2019.Areas covered: This article summarizes our up-to-date knowledge on the pathophysiologic role of XPO-1 in MM. Furthermore, it reviews the most recent clinical data on selinexor in combination with dexamethasone and other anti-MM agents; and discusses its safety profile, management strategies; and potential future developments.Expert opinion: Selinexor represents a next-generation-novel agent with an innovative mechanism of action that marks a significant advance in the treatment of heavily pretreated MM patients. Ongoing studies investigate its therapeutic potential also in earlier lines of therapy. Additional data is needed to confirm that selinexor and other SINE compounds are a valuable addition to our current therapeutic armamentarium.

Variation in use of postoperative chemoradiation following surgery for T1 and T2 oropharyngeal squamous cell carcinoma; National Cancer Database.

BACKGROUND AND OBJECTIVES: Primary surgical treatment of patients with early T-classification (T1-T2) oropharyngeal squamous cell carcinoma (OPSCC) has increased. We sought to determine how often these patients receive postoperative chemoradiation (CRT). METHODS: Patients with T1-T2 OPSCC in the National Cancer Database who underwent primary surgery were evaluated for receipt of postoperative CRT. Postoperative CRT use was examined among patients with high risk factors (positive margins and/or extracapsular spread [ECS]), intermediate risk factors (negative margins, no ECS, and either pT3-4 and/or N2-N3), and no apparent risk factors. RESULTS: Of 4833 patients with T1-T2 OPSCC who underwent primary surgery, 43% had high risk pathologic factors, of whom only 63% received postoperative CRT. Another 31% had no apparent risk factors, of whom 16% nonetheless received postoperative CRT. On multivariable analysis, in addition to tumor and demographic factors, patients treated at community hospitals were more likely to receive postoperative CRT (O.R. 1.41 C.I. 1.18-1.87, P = 0.001). CONCLUSIONS: Variation in postoperative CRT use indicates a lack of consensus and/or knowledge about its benefits and indications. Usage of postoperative CRT regardless of pathologic risk factors suggests an area where future efforts at implementation of best practices may be targeted.

Return to the Primary Acute Care Service Among Patients With Multiple Myeloma on an Acute Inpatient Rehabilitation Unit.

BACKGROUND: Pancytopenia, immunosuppression, and other factors may place patients with multiple myeloma at risk for medical complications. These patients often require inpatient rehabilitation. No previous studies have looked at risk factors for return to the primary acute care service of this patient population. OBJECTIVE: To determine the percentage of and factors associated with return to the primary acute care service of multiple myeloma rehabilitation inpatients. DESIGN: Retrospective review. SETTING: Acute inpatient rehabilitation unit within a National Cancer Institute Comprehensive Cancer Center. PARTICIPANTS: All patients with multiple myeloma admitted to the inpatient rehabilitation unit between March 1, 2004, and February 28, 2015. MAIN OUTCOME MEASURES: Return to the primary acute care service was analyzed with demographic information, multiple myeloma characteristics, medications, laboratory values, and hospital admission characteristics. RESULTS: One hundred forty-three inpatient rehabilitation admissions were found during the study period. After we removed multiple admissions of the same patients and planned transfers to the primary acute care service, 122 admissions were analyzed. Thirty-two (26%) patients transferred back to the primary acute care service for unplanned reasons. Multivariate analysis revealed male gender and thrombocytopenia as significantly associated with return to the primary acute care service. The median survival of patients who transferred back to the inpatient primary acute care service was 180 days versus 550 days for those who did not (P < .001). CONCLUSION: Because of their medical fragility, clinicians caring for rehabilitation inpatients with multiple myeloma should maintain close contact with the primary oncology service. Factors associated with an increased risk of transfer back to the primary acute care service include male gender and thrombocytopenia. LEVEL OF EVIDENCE: IV.

Management of Invasive Differentiated Thyroid Cancer.

BACKGROUND: Invasive disease is a poor prognostic factor for patients with differentiated thyroid cancer (DTC). Uncontrolled central neck disease is a common cause of distressing death for patients presenting in this manner. Advances in assessment and management of such cases have led to significant improvements in outcome for this patient group. This article reviews the patterns of invasion and a contemporary approach to investigation and treatment of patients with invasive DTC. SUMMARY: Aerodigestive tract invasion is reported in around 10% of case series of DTC. Assessment should include not only clinical history and physical examination with endoscopy as indicated, but ultrasound and contrast-enhanced cross-sectional imaging. Further studies including positron emission tomography should be considered, particularly in recurrent cases that are radioactive iodine (RAI) resistant. Both the patient and the extent of disease should be carefully assessed prior to embarking on surgery. The aim of surgery is to resect all gross disease. When minimal visceral invasion is encountered early, "shave" procedures are recommended. In the setting of transmural invasion of the airway or esophagus, however, full thickness excision is required. For intermediate cases in which invasion of the viscera has penetrated the superficial layers but is not evident in the submucosa, opinion is divided. Early reports recommended an aggressive approach. More recently authors have tended to recommend less aggressive resections with postoperative adjuvant therapies. The role of external beam radiotherapy continues to evolve in DTC with support for its use in patients considered to have RAI-resistant tumors. CONCLUSIONS: Patients with invasive DTC require a multidisciplinary approach to investigation and treatment. With detailed assessment, appropriate surgery, and adjuvant therapy when indicated, this patient group can expect durable control of central neck disease, despite the aggressive nature of their primary tumors.

Defining a Valid Age Cutoff in Staging of Well-Differentiated Thyroid Cancer.

BACKGROUND: Age 45 years is used as a cutoff in the staging of well-differentiated thyroid cancer (WDTC) as it represents the median age of most datasets. The aim of this study was to determine a statistically optimized age threshold using a large dataset of patients treated at a comprehensive cancer center. METHODS: Overall, 1807 patients with a median follow-up of 109 months were included in the study. Recursive partitioning was used to determine which American Joint Committee on Cancer (AJCC) variables were most predictive of disease-specific death, and whether a different cutoff for age would be found. From the resulting tree, a new age cutoff was picked and patients were restaged using this new cutoff. RESULTS: The 10-year disease-specific survival (DSS) by Union for International Cancer Control (AJCC/UICC) stage was 99.6, 100, 96, and 81 % for stages I-IV, respectively. Using recursive partitioning, the presence of distant metastasis was the most powerful predictor of DSS. For M0 patients, age was the next most powerful predictor, with a cutoff of 56 years. For M1 patients, a cutoff at 54 years was most predictive. Having reviewed the analysis, age 55 years was selected as a more robust age cutoff than 45 years. The 10-year DSS by new stage (using age 55 years as the cutoff) was 99.2, 98, 100, and 74 % for stages I-IV, respectively. CONCLUSION: A change in age cutoff in the AJCC/UICC staging for WDTC to 55 years would improve the accuracy of the system and appropriately prevent low-risk patients being overstaged and overtreated.

Role of RAI in the management of incidental N1a disease in papillary thyroid cancer.

BACKGROUND: Following total thyroidectomy (TT) for papillary thyroid cancer (PTC), pathological assessment can occasionally reveal incidental perithyroidal lymph nodes (LNs) with occult metastases. These cN0pN1a patients often receive radioactive iodine (RAI) therapy for this indication alone. The aim of this study was to determine the central compartment nodal recurrence-free survival in patients treated without RAI compared to those who received RAI treatment. METHODS: An institutional database of 3664 previously untreated patients with differentiated thyroid cancer operated between 1986 and 2010 was reviewed. A total of 232 pT1-3 patients managed with TT and no neck dissection were subsequently found to have incidental level 6 LNs on pathology. Patients with other indications for RAI, such as extrathyroidal extension and close or positive margins, were excluded. One hundred and four patients remained for analysis. Kaplan-Meier method was used to determine central neck LN recurrence-free survival (RFS). RESULTS: The median age of the cohort was 40 years (range 17-83). The median follow-up was 53 months (range 1-211). The median number of positive LNs removed and maximum LN diameter were 1 (range 1-8) and 5 mm (range 1-16 mm), respectively. A total of 67 (64%) patients had adjuvant RAI and 37 (36%) did not. Patients with vascular invasion (P = 0·01), LNs >2 mm (P = 0·07) and >2 positive nodes (P = 0·06) were more likely to be selected for adjuvant RAI therapy. Patients without RAI therapy had similar 5-year central neck LN RFS compared to those treated with RAI: 96·2% vs 94·6%, respectively (P = 0·92). CONCLUSION: There is no difference in the 5-year central compartment nodal recurrence-free survival in patients treated without RAI compared to those who received RAI treatment.

Microscopic Positive Margins in Differentiated Thyroid Cancer Is Not an Independent Predictor of Local Failure.

BACKGROUND: In contrast to other head and neck cancers, the impact of histological thyroid specimen margin status in differentiated thyroid cancer (DTC) is not well understood. The aim of this study was to investigate the prognostic value of margin status on local recurrence in DTC. METHOD: The records of 3664 consecutive patients treated surgically for DTC between 1986 and 2010 were identified from an institutional database. Patients with less than total thyroidectomy, unresectable or gross residual disease, or M1 disease at presentation and those with unknown pathological margin status were excluded from analysis. In total, 2616 patients were included in the study; 2348 patients (90%) had negative margins and 268 patients (10%) had positive margins. Microscopic positive margin status was defined as tumor present at the specimen's edge on pathological analysis. Patient, tumor, and treatment characteristics were compared by Pearson's chi-squared test. Local recurrence free survival (LRFS) was calculated for each group using the Kaplan Meier method. RESULTS: The median age of the cohort was 48 years (range 7-91 years) and the median follow-up was 50 months (range 1-330 months). Age, sex, and histology types were similar between groups. As expected, patients who had positive margins were more likely to have larger tumors (p<0.001), extrathyroidal extension (ETE) (p<0.001), multicentric disease (p<0.001), or nodal disease (p<0.001) and were more likely to receive adjuvant radioactive iodine therapy (p<0.001) as well as external beam radiotherapy (p<0.001). The LRFS at 5 years for patients with positive margins status was slightly poorer compared with patients with negative margins (98.9% vs. 99.5%, p=0.018). Twelve patients developed local recurrence-8/2348 (0.34%) patients with negative margins and 4/263 (1.52%) patients with positive margins. Univariate predictors of LRFS were sex (p=0.006), gross ETE (<0.001), and positive margins (p=0.018). However, when controlling for presence of gross ETE on multivariate analysis, microscopic positive margin status was not an independent predictor of LRFS (p=0.193). CONCLUSION: Patients with resectable, M0 disease that undergo total thyroidectomy have an excellent five year LRFS of 99.4%. Microscopic positive margin status was not a significant predictor for local failure after adjusting for ETE or pathological tumor (pT) stage.

Connect MM Registry: The Importance of Establishing Baseline Disease Characteristics.

BACKGROUND: Connect MM is the first and largest observational, noninterventional, prospective registry of patients newly diagnosed with multiple myeloma (NDMM) in the United States. It collects longitudinal data on patients within clinical practice including patients in clinical trials. PATIENTS AND METHODS: Of the 1513 patients enrolled, 1493 were protocol-eligible. RESULTS: Median age was 67 years, 81.9% (1223/1493) were Caucasian, and 57.2% (854/1493) were male. Of these patients, 26.5% (232/877) were International Staging System stage I, 34.9% (306/877) stage II, and 38.7% (339/877) stage III. Eastern Cooperative Oncology Group performance status of 0/1/2 were reported in 96.6% (1017/1053). Clonal plasma cells > 10% were found in 91.6% (1282/1399) of patients and M-component in 98.8% (1343/1359). Hypercalcemia was present in 7.3% (108/1481) of patients, serum creatinine > 2 mg/dL in 18.3% (271/1484), anemia in 45.1% (673/1493), and bone involvement in 76.7% (1143/1490). Of the 15 National Comprehensive Cancer Network (NCCN) recommended diagnostic tests, a median of 12 were performed. Lactate dehydrogenase assessment, serum free light chain ratio, and immunofixation were reported in 38.4% (574/1493), 62.1% (927/1493), and 66% (985/1493) of patients, respectively. Quantitative immunoglobulin, ß-2 microglobulin, and protein electrophoresis (serum or urine) were reported in 72.3% (1080/1493), 74.1% (1107/1493), and 78.0% (1164/1493) of patients, respectively. Bone marrow biopsy was reported in 92.2% (1376/1493), but conventional cytogenetic and fluorescence in situ hybridization analysis were reported in only 63.2% (944/1493) and 59.8% (893/1493) of patients, respectively. A high-risk cytogenetic profile (according to International Myeloma Working Group [IMWG] criteria) was found in 16.9% (253/1493). CONCLUSION: This analysis provides insight into the demographic and disease characteristics of NDMM patients in a range of clinical practices. Creating solid records of baseline patient disease characteristics using suggested NCCN diagnostic work-up and IMWG criteria provides a foundation for monitoring disease progression and response to treatment.

Thyroid carcinoma, version 2.2014.

These NCCN Guidelines Insights focus on some of the major updates to the 2014 NCCN Guidelines for Thyroid Carcinoma. Kinase inhibitor therapy may be used to treat thyroid carcinoma that is symptomatic and/or progressive and not amenable to treatment with radioactive iodine. Sorafenib may be considered for select patients with metastatic differentiated thyroid carcinoma, whereas vandetanib or cabozantinib may be recommended for select patients with metastatic medullary thyroid carcinoma. Other kinase inhibitors may be considered for select patients with either type of thyroid carcinoma. A new section on "Principles of Kinase Inhibitor Therapy in Advanced Thyroid Cancer" was added to the NCCN Guidelines to assist with using these novel targeted agents.

Primary tumor staging for oral cancer and a proposed modification incorporating depth of invasion: an international multicenter retrospective study.

IMPORTANCE: The current American Joint Committee on Cancer (AJCC) staging system for oral cancer demonstrates wide prognostic variability within each primary tumor stage and provides suboptimal staging and prognostic information for some patients. OBJECTIVE: To determine if a modified staging system for oral cancer that integrates depth of invasion (DOI) into the T categories improves prognostic performance compared with the current AJCC T staging. DESIGN, SETTING, AND PARTICIPANTS: Retrospective analysis of 3149 patients with oral squamous cell carcinoma treated with curative intent at 11 comprehensive cancer centers worldwide between 1990 and 2011 with surgery ± adjuvant therapy, with a median follow-up of 40 months. MAIN OUTCOMES AND MEASURES: We assessed the impact of DOI on disease-specific and overall survival in multivariable Cox proportional hazard models and investigated for institutional heterogeneity using 2-stage random effects meta-analyses. Candidate staging systems were developed after identification of optimal DOI cutpoints within each AJCC T category using the Akaike information criterion (AIC) and likelihood ratio tests. Staging systems were evaluated using the Harrel concordance index (C-index), AIC, and visual inspection for stratification into distinct prognostic categories, with internal validation using bootstrapping techniques. RESULTS: The mean and median DOI were 12.9 mm and 10.0 mm, respectively. On multivariable analysis, DOI was a significantly associated with disease-specific survival (P < .001), demonstrated no institutional prognostic heterogeneity (I² = 6.3%; P = .38), and resulted in improved model fit compared with T category alone (lower AIC, P < .001). Optimal cutpoints of 5 mm in T1 and 10 mm in T2-4 category disease were used to develop a modified T staging system that was preferred to the AJCC system on the basis of lower AIC, visual inspection of Kaplan-Meier curves, and significant improvement in bootstrapped C-index. CONCLUSIONS AND RELEVANCE: We propose an improved oral cancer T staging system based on incorporation of DOI that should be considered in future versions of the AJCC staging system after external validation.

Electroacupuncture for thalidomide/bortezomib-induced peripheral neuropathy in multiple myeloma: a feasibility study.

BACKGROUND: This single-arm study evaluated feasibility, safety, and initial efficacy of electroacupuncture for thalidomide/bortezomib-induced peripheral neuropathy (PN) in cancer patients with multiple myeloma. METHODS: Patients with neuropathy ≥ grade 2 received 20 acupuncture treatments over 9 weeks. RESULTS: For the 19 evaluable patients, Functional Assessment of Cancer Therapy/Gynecological Oncology Group-Neurotoxicity (FACT/GOG/NTX) mean (SD) scores improved significantly between baseline and week 13 (20.8 [9.6] vs 13.2 [8.5], p = 0.0002). Moderate effect size differences began on week 4, with the largest effect size differences found at week 9 for FACT/GOG/NTX scores, worst pain in the last 24 hours, and pain severity (Cohen's d = 1.43, 1.19, and 1.08, respectively) and continuing through week 13 (Cohen's d = 0.86, 0.88, and 0.90, respectively). From baseline to week 13, additional significant improvements were seen as follows: postural stability (1.0 [0.6] vs 0.8 [0.4], p = 0.02); coin test (10.0 [7.4] vs 5.6 [1.9], p < 0.0001); button test (96.1 [144.4] vs 54.9 [47.3], p < 0.0001); and walking test (21.6 [10.0] vs 17.2 [7.7], p = 0.0003). No significant changes were seen with NCS. CONCLUSIONS: Acupuncture may help patients experiencing thalidomide- or bortezomib-induced PN. Larger, randomized, clinical trials are needed. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00891618.

Minimum nodal yield in oral squamous cell carcinoma: defining the standard of care in a multicenter international pooled validation study.

PURPOSE: There is evidence to suggest that a nodal yield <18 is an independent prognostic factor in patients with clinically node negative (cN0) oral squamous cell carcinoma (SCC) treated with elective neck dissection (END). We sought to evaluate this hypothesis with external validation and to investigate for heterogeneity between institutions. PATIENTS AND METHODS: We analyzed pooled individual data from 1,567 patients treated at nine comprehensive cancer centers worldwide between 1970 and 2011. Nodal yield was assessed with Cox proportional hazard models, stratified by study center, and adjusted for age, sex, pathological T and N stage, margin status, extracapsular nodal spread, time period of primary treatment, and adjuvant therapy. Two-stage random-effects meta-analyses were used to investigate for heterogeneity between institutions. RESULTS: In multivariable analyses of patients undergoing selective neck dissection, nodal yield <18 was associated with reduced overall survival [hazard ratio (HR) 1.69; 95 % confidence interval (CI) 1.22-2.34; p = 0.002] and disease-specific survival (HR 1.88; 95 % CI 1.21-2.91; p = 0.005), and increased risk of locoregional recurrence (HR 1.53; 95 % CI 1.04-2.26; p = 0.032). Despite significant differences between institutions in terms of patient clinicopathological factors, nodal yield, and outcomes, random-effects meta-analysis demonstrated no evidence of heterogeneity between centers in regards to the impact of nodal yield on disease-specific survival (p = 0.663; I (2) statistic = 0). CONCLUSION: Our data confirm that nodal yield is a robust independent prognostic factor in patients undergoing END for cN0 oral SCC, and may be applied irrespective of the underlying patient population and treating institution. A minimum adequate lymphadenectomy in this setting should include at least 18 nodes.

Malignancy rate in thyroid nodules classified as Bethesda category III (AUS/FLUS).

BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology is the standard for interpreting fine needle aspiration (FNA) specimens. The "atypia of undetermined significance/follicular lesion of undetermined significance" (AUS/FLUS) category, known as Bethesda Category III, has been ascribed a malignancy risk of 5-15%, but the probability of malignancy in AUS/FLUS specimens remains unclear. Our objective was to determine the risk of malignancy in thyroid FNAs categorized as AUS/FLUS at a comprehensive cancer center. METHODS: The management of 541 AUS/FLUS thyroid nodule patients treated at Memorial Sloan-Kettering Cancer Center between 2008 and 2011 was analyzed. Clinical and radiologic features were examined as predictors for surgery. Target AUS/FLUS nodules were correlated with surgical pathology. RESULTS: Of patients with an FNA initially categorized as AUS/FLUS, 64.7% (350/541) underwent immediate surgery, 17.7% (96/541) had repeat FNA, and 17.6% (95/541) were observed. Repeat FNA cytology was unsatisfactory in 5.2% (5/96), benign in 42.7% (41/96), AUS/FLUS in 38.5% (37/96), suspicious for follicular neoplasm in 5.2% (5/96), suspicious for malignancy in 4.2% (4/96), and malignant in 4.2% (4/96). Of nodules with two consecutive AUS/FLUS diagnoses that were resected, 26.3% (5/19) were malignant. Among all index AUS/FLUS nodules (triaged to surgery, repeat FNA, or observation), malignancy was confirmed on surgical pathology in 26.6% [CI 22.4-31.3]. Among AUS/FLUS nodules triaged to surgery, the malignancy rate was 37.8% [CI 33.1-42.8]. Incidental cancers were found in 22.3% of patients. On univariate logistic regression analysis, factors associated with triage to surgery were younger patient age (p<0.0001), increasing nodule size (p<0.0001), and nodule hypervascularity (p=0.032). CONCLUSIONS: In patients presenting to a comprehensive cancer center, malignancy rates in nodules with AUS/FLUS cytology are higher than previously estimated, with 26.6-37.8% of AUS/FLUS nodules harboring cancer. These data imply that Bethesda Category III nodules in some practice settings may have a higher risk of malignancy than traditionally believed, and that guidelines recommending repeat FNA or observation merit reconsideration.

A new care paradigm in geriatric head and neck surgical oncology.

BACKGROUND AND OBJECTIVES: Perioperative management of elderly patients with head and neck cancer poses unique challenges. Our objective is to describe the implementation and feasibility of a novel intervention designed to improve perioperative care in geriatric head and neck surgery. METHODS: This pilot study was performed in a single-institution, NCI-designated comprehensive cancer center. All surgical patients with head and neck cancer over age 75 were offered perioperative consultation with fellowship-trained geriatricians focusing in geriatric oncology. RESULTS: Between 2010 and 2011, a total of 168 patients requiring head and neck surgery were seen by the geriatric service, of which 94% subsequently underwent surgery. Apart from preoperative medical optimization, geriatricians assisted in complex decision-making regarding the indications for cancer-directed therapy. Postoperatively, they assisted in preventing and treating delirium and poly-pharmacy, facilitating discharge planning, and initiating rehabilitation. Postoperatively, 87% were discharged home, and 13% required placement in skilled nursing facilities. At 24 months, overall survival was 80%. Patients, surgeons and geriatricians alike were enthusiastic about the initiative, which is expanding within the institution. CONCLUSION: Geriatric perioperative support for elderly head and neck cancer patients is well-received with promising potential. The tangible impact and direct benefits of this pilot initiative require additional study.

The results of selective use of radioactive iodine on survival and on recurrence in the management of papillary thyroid cancer, based on Memorial Sloan-Kettering Cancer Center risk group stratification.

BACKGROUND: The American Thyroid Association guidelines recommend the routine use of radioactive iodine for remnant ablation (RRA) in all T3 or greater primary tumors, and selective use in patients with intrathyroidal disease >1 cm, or evidence of nodal metastases. The guidelines recognize that there is conflicting and inadequate data to make firm recommendations for most patients. The aim of this study was to analyze our institutional experience of the use of RRA in the management of papillary thyroid cancer, with a particular focus on outcomes for those patients selected not to receive RRA. METHODS: We retrospectively reviewed 1129 consecutive patients who underwent total thyroidectomy at the Memorial Sloan-Kettering Cancer Center between 1986 and 2005. Of these, 490 were pT1-2 N0, 193 pT1-2 N1, and 444 pT3-4. Details on recurrence and disease-specific survival were recorded by the Kaplan-Meier method and compared using the log-rank test. RESULTS: The five-year disease-specific survival and recurrence-free survival in the pT1/T2 N0, pT1-2 N1, and pT3-4 were 100% and 92%, 100% and 92%, and 98% and 87% respectively. Low-risk patients who were managed without RRA (who tended to have limited primary disease, pT1-2, and low-volume metastatic disease in the neck, pT1-2 N1-fewer than five nodes, all <1 cm greatest dimension) had five-year recurrence-free survival of >97%. In the group with advanced local tumors (pT3-4), those patients who did not receive RRA (who tended to have pT3 N0 disease) had five-year recurrence-free survival of >90%. CONCLUSION: Following appropriate surgical management, the majority of patients with low-risk local disease and even some patients with more advanced-stage (pT3) tumors or regional metastases have low rates of recurrence and high rates of survival when managed without RRA.

Zoledronic acid for prevention of bone loss in patients receiving primary therapy for lymphomas: a prospective, randomized controlled phase III trial.

UNLABELLED: In patients with newly diagnosed lymphoma, low bone mineral density (BMD) is common at diagnosis and worsens with therapy. Our randomized phase III trial demonstrates that 2 doses of zoledronic acid (ZA) and supplementation with calcium and vitamin D effectively prevent further bone loss. BACKGROUND: Patients with lymphoma are at risk of development of bone mineral density (BMD) loss from therapy with high-dose corticosteroids and alkylating agents. Zoledronic acid (ZA), a bisphosphonate, may prevent this complication of therapy. We evaluated the effect of ZA on the change in BMD and surrogate biomarkers in patients with lymphoma receiving initial chemotherapy. PATIENTS AND METHODS: Our phase III trial randomized 74 patients with newly diagnosed lymphoma and a baseline BMD of ≥ -2.0 to receive oral calcium and vitamin D daily with or without ZA at enrollment and at 6 months after enrollment. BMD was evaluated at baseline and 1 year after enrollment. Secondary biomarker endpoints were collected at baseline and at 3, 6, 9, and 12 months after enrollment. RESULTS: Forty-three percent of patients had baseline osteopenia. Fifty-three patients were evaluable for response: 24 received ZA and had stable BMD during the observation period, whereas 29 patients in the control group had decreased BMD (P < .05 at lumbar spine and bilateral femoral neck). Twenty-one randomized patients were not evaluable for response because of lymphoma progression or death, withdrawn consent/incomplete testing, or ineligibility. Bone biomarkers were higher in the control group at all intervals after treatment (P < .001). No fractures or intervention-related toxicities were observed during this trial. CONCLUSIONS: Newly diagnosed patients with lymphoma are at risk of low BMD, which may worsen with therapy. Treatment with ZA effectively stabilizes BMD and prevents bone loss. Our data suggest that BMD testing and prophylaxis should be considered as an early intervention for a preventable problem.
