RESUMEN
The National Comprehensive Cancer Network guidelines provide evidence-based consensus for optimal individual site- and stage-specific treatments. This is a cohort study of 11,121 late-stage oral cancer patients in the National Cancer Database from 2010 to 2016. We hypothesized that patient travel distance may affect treatment choices and impact outcome. We split travel distance (miles) into quartiles (D1-4) and assessed treatment choices, type of facility, and survival outcome in relation to distance traveled. Univariate and multivariate analyses addressed contributions of specific variables. White patients were most likely to travel farthest (D4) for treatment compared to Black patients (D1). Urban area patients traveled shorter distances than those from rural areas. Greater travel distance was associated with patients undergoing surgical-based therapies and treatment at academic centers. Patients in D1 had the lowest median survival of all distance quartiles. Surgery-based multimodality treatment (surgery and radiation) had a median survival significantly greater than for non-surgical therapy. Several factors including travel distance and treatment facility were associated with survival outcomes for late-stage oral cavity cancers. Consideration of these factors may help improve the outcome for this patient population.
RESUMEN
PURPOSE: There is compelling evidence that CD4+ and CD8+T cells are dysfunctional in multiple myeloma, compromising their ability to control disease progression. Pre-clinical models suggest that exercise represents a non-pharmacologic means to reduce immune exhaustion, but no studies to date have examined the relationship between an exercise intervention and biomarkers of immune exhaustion in multiple myeloma patients. PATIENTS AND METHODS: The current study includes 24 multiple myeloma patients who participated in a six-month physical activity intervention, consisting of supervised strength training (n = 12) and unsupervised home-based walking arms (n = 12). Comprehensive flow cytometry was utilized to assess the frequency of CD4+ and CD8+T cells and subpopulations expressing the markers of exhaustion PD-1, TIGIT, TIM3 and/or LAG3. Ratios of exhausted to non-exhausted cell populations, and percentages of exhausted to total populations of the same lineage, were calculated for the baseline and final timepoints. RESULTS: Eighteen of 20 exhaustion measures were lower at the end of the intervention than at baseline, and several were significantly or borderline significantly reduced in the entire sample or in one of the arms. The entire sample saw improvements in the ratios of CD4+ TIGIT+ to non-exhausted CD4+ (0.7 [0.6] to 0.6 [0.4], P = .04) and CD8+ PD1+ to non-exhausted CD8+ (1.8 [2.6] to 1.5 [2.0], P = .06), and in total exhausted CD8+ as a percent of total CD8+ (72.9 [21.9] to 68.3 [19.6], P < .01). CONCLUSIONS: This pilot study suggests that physical activity induces changes in MM patients' immune systems, potentially rendering a less exhausted T cell state.

PURPOSE: Early-onset colorectal cancer (EOCRC), defined as CRC diagnosed before age 50 years, has increased significantly worldwide. The majority of EOCRCs do not appear to be driven by genetic factors and may be influenced by environmental factors. We hypothesized that sociodemographic disparities exist in EOCRC. The purpose was of the study was to examine the geographic disparities in patients with EOCRC. METHODS: We retrospectively examined the SEER database from 1976 to 2016 to examine the geographic disparities in EOCRC. A total of 73,378 patients with EOCRC were included in the analysis. We performed univariate and multivariable analyses to evaluate overall survival (OS) and disease-specific survival (DSS). Sociodemographic factors, including the location of residence (metropolitan areas [MA] or rural areas [RA]), sex, race, insurance status, and marital status, were included in the statistical analysis. RESULTS: The incidence and mortality rates were consistently higher in RA versus MA during the study period. Multivariable analysis showed that patients living in RA had worse OS (hazard ratio [HR], 1.14; P < .01) and DSS (HR, 1.15; P < .001) compared with those living in MA. Similarly, non-Hispanic Black ethnicity and uninsured patients had significantly worse survival when compared with non-Hispanic White and insured patients, respectively. Married status showed better survival outcomes. CONCLUSION: Patients with EOCRC living in RA have worse outcomes. Understanding the mechanisms behind such socioeconomic disparities is important so that future studies can reduce these disparities.

BACKGROUND: Presence of cytotoxic T lymphocytes (CTL) in the tumor microenvironment (TME) predicts the effectiveness of cancer immunotherapies. The ability of toll-like receptor 3 (TLR3) ligands, interferons (IFNs) and COX2 inhibitors to synergistically induce CTL-attracting chemokines (but not regulatory T cell (Treg)-attractants) in the TME, but not in healthy tissues, observed in our preclinical studies, suggested that their systemic application can reprogram local TMEs. METHODS: Six evaluable patients (33-69 years) with metastatic triple-negative breast cancer received six doses of systemic chemokine-modulating (CKM) regimen composed of TLR3 ligand (rintatolimod; 200 mg; intravenous), IFN-α2b (20 MU/m2; intravenous) and COX2 inhibitor (celecoxib; 2×200 mg; oral) over 2 weeks. The predetermined primary endpoint was the intratumoral change in the expression of CTL marker, CD8α, in the post-CKM versus pre-CKM tumor biopsies. Patients received follow-up pembrolizumab (200 mg, intravenously, every 3 weeks), starting 3-8 days after completion of CKM. RESULTS: Post-CKM biopsies showed selectively increased CTL markers CD8α (average 10.2-fold, median 5.5-fold, p=0.034) and granzyme B (GZMB; 6.1-fold, median 5.8-fold, p=0.02), but not FOXP3 (Treg marker) relative to HPRT1 expression, resulting in the increases in average CD8α/FOXP3 ratio and GZMB/FOXP3 ratio. CKM increased intratumoral CTL-attractants CCL5 and CXCL10, but not Treg-attractants CCL22 or CXCL12. In contrast, CD8+ T cells and their CXCR3+ subset showed transient decreases in blood. One clinical response (breast tumor autoamputation) and three stable diseases were observed. The patient with clinical response remains disease free, with a follow-up of 46 months as of data cut-off. CONCLUSIONS: Short-term systemic CKM selectively increases CTL numbers and CTL/Treg ratios in the TME, while transiently decreasing CTL numbers in the blood. Transient effects of CKM suggest that its simultaneous application with checkpoint blockade and other forms of immunotherapy may be needed for optimal outcomes.

Introduction: In stage IV NSCLC with solitary or oligometastatic brain metastasis, surgical resection of the primary and definitive management of the brain metastasis is an accepted standard. However, the effect of systemic chemotherapy after surgical resection on overall survival is not well-established. Methods: We used the National Cancer Database to retrospectively identify individuals with NSCLC as the primary tumor along with synchronous brain metastases who underwent thoracic resection with or without adjuvant chemotherapy. Chi-square and Wilcoxon rank sum tests were performed to compare categorical and continuous variables, respectively, across the treatment groups. Kaplan-Meier and Cox proportional modeling were done to determine the survival benefit. Results: A total of 310 (71.9%) of the cohort received perioperative chemotherapy, most of whom (79.4%) received it in the adjuvant setting. Patients receiving chemotherapy were likely to be younger (p = 0.002), privately insured (p = 0.01), and receive radiation (p < 0.001). Perioperative chemotherapy was significantly associated with survival on both univariate (hazard ratio = 0.71[0.52 - 0.99]) and multivariable (hazard ratio = 0.66 [0.47 - 0.92]) in addition to age (p = 0.03), Charlson-Deyo score (p = 0.02), pathologic N stage (p = 0.02), and adenocarcinoma histology (p = 0.02). Kaplan-Meier analysis confirmed this result with a significantly better survival with perioperative chemotherapy (p = 0.02). Further subgroup analysis using pathologic N stage revealed similar effect in pN1 (p = 0.001), but not pN0 (p = 0.2) patients. Conclusions: Perioperative chemotherapy for pN0-1 NSCLC with synchronous brain metastasis is associated with improved OS in this analysis.
RESUMEN
BACKGROUND: Our previous research on neuroendocrine and gastric cancers has shown that patients living in rural areas have worse outcomes than urban patients. This study aimed to investigate the geographic and sociodemographic disparities in esophageal cancer patients. METHODS: We conducted a retrospective study on esophageal cancer patients between 1975 and 2016 using the Surveillance, Epidemiology, and End Results database. Both univariate and multivariable analyses were performed to evaluate overall survival (OS) and disease-specific survival (DSS) between patients residing in rural (RA) and urban (MA) areas. Further, we used the National Cancer Database to understand differences in various quality of care metrics based on residence. RESULTS: N = 49,421 (RA [12%]; MA [88%]). The incidence and mortality rates were consistently higher during the study period in RA. Patients living in RA were more commonly males (p < 0.001), Caucasian (p < 0.001), and had adenocarcinoma (p < 0.001). Multivariable analysis showed that RA had worse OS (HR = 1.08; p < 0.01) and DSS (HR = 1.07; p < 0.01). Quality of care was similar, except RA patients were more likely to be treated at a community hospital (p < 0.001). CONCLUSIONS: Our study identified geographic disparities in esophageal cancer incidence and outcomes despite the similar quality of care. Future research is needed to understand and attenuate such disparities.
RESUMEN
The CORAL study highlighted the need to develop novel salvage regimens in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) previously treated with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone. Carfilzomib (CFZ) can overcome rituximab chemotherapy resistance in lymphoma preclinical models by targeting the ubiquitin-proteasome system. We conducted an investigator initiated, single-center, open-label, prospective phase 1 study evaluating the safety and efficacy of CFZ in combination with rituximab, ifosfamide, carboplatin, and etoposide (C-R-ICE) in high-dose chemotherapy with autologous stem cell transplant (HDC-ASCT) eligible patients with R/R DLBCL (NCT01959698). In the dose-escalation phase, 18 patients were enrolled at 6 dose levels with no dose-limiting toxicities noted. CFZ 45 mg/m2 was selected as the recommended dose for expansion. Eleven additional patients were enrolled in the dose-expansion phase. Overall response rate (ORR) was 66% (48% CR; 17% PR); 52% patients underwent HDC-ASCT. An ORR of 85% was observed in patients with nongerminal center B-cell-like (non-GCB) DLBCL compared with only 13% in those with GCB DLBCL. Median progression-free survival (PFS) was 15.2 months (5.1 months, not reached [NR]), and median overall survival (OS) was 22.6 months (6.8 months, NR). Patients with non-GCB subtype had a significantly longer PFS (NR vs 6.6 months; P = .0001) and OS (NR vs 6.6 months; P = .001) than those with GCB subtype. C-R-ICE is well tolerated in patients with R/R DLBCL with toxicities comparable to rituximab, ifosfamide, carboplatin, and etoposide therapy. Our data show that patients with non-GCB DLBCL benefit significantly from incorporating CFZ into second-line therapy and HDC-ASCT.

Background: CIMAvax-EGF is an epidermal growth factor (EGF)-depleting immunotherapy which has shown survival benefit as a switch maintenance treatment after platinum-based chemotherapy in advanced non-small cell lung cancer (NSCLC). The primary objective of this trial is to establish the safety and recommended phase II dose (RP2D) of CIMAvax-EGF in combination with nivolumab as second-line therapy for NSCLC. Methods: Patients with immune checkpoint inhibitor-naive metastatic NSCLC were enrolled using a "3+3" dose-escalation design. Toxicities were graded according to CTCAE V4.03. Thirteen patients (one unevaluable), the majority with PD-L1 0%, were enrolled into two dose levels of CIMAvax-EGF. Findings: The combination was determined to be safe and tolerable. The recommended phase 2 dose of CIMAvax-EGF was 2.4 mg. Humoral response to CIMAvax-EGF was achieved earlier and in a greater number of patients with the combination compared to historical control. Four out of 12 evaluable patients had an objective response.
RESUMEN
BACKGROUND: In addition to treating hyperlipidemia and atherosclerosis, statins have demonstrated anti-inflammatory and antitumor activity in various cancers. We evaluate this effect in esophageal cancer patients undergoing esophagectomy. METHODS: Esophageal cancer patients undergoing esophagectomy at Roswell Park Comprehensive Cancer Center between March 2007 and December 2015 were included. Association between presurgery statin use and relevant variables with overall survival (OS), disease-specific survival (DSS), and recurrence-free survival (RFS) was analyzed using Cox hazards. Survival analyses were independently performed for body mass index (BMI)-based subgroups. RESULTS: There was no significant association between statin use and outcomes overall. However, in subgroup analysis, there was significant association between statin use and outcomes in patients with BMI ≥ 30. Multivariable analysis in obese patients demonstrated the association of statins with improved OS (hazard ratio [HR]: 0.46, p = 0.025), DSS (HR: 0.39, p = 0.015), and RFS (HR: 0.38, p = 0.022). The only other variable significantly associated with all three outcome measures was stage. CONCLUSIONS: Statin use is associated with improved OS, DSS, and RFS of obese patients in resected esophageal cancer. BMI could be investigated as a biomarker for adjunctive statin use in future studies.

BACKGROUND: Ofatumumab is a humanized type 1 anti-CD20 monoclonal antibody. Preclinical studies show improved complement-mediated cytotoxicity (CMC) compared to rituximab in mantle cell lymphoma (MCL). This study evaluates the safety and efficacy of combining ofatumumab with HyperCVAD/MA (O-HyperCVAD) in newly diagnosed MCL. METHODS: In this single-arm phase 2 study, 37 patients were treated with the combination of O-HyperCVAD for 4 or 6 cycles, followed by high dose chemotherapy and autologous stem cell transplant. Primary objectives were overall response rate (ORR) and complete response (CR) rate at the end of therapy. Secondary objectives included minimal residual disease (MRD) negativity, progression-free survival (PFS), and overall survival (OS). RESULTS: Median age was 60 years; ORR was 86% and 73% achieved a CR by modified Cheson criteria. The MRD negativity rate was 78% after 2 cycles of therapy, increasing to 96% at the end of induction; median PFS and OS were 45.5 months and 56 months, respectively. Achieving a post-induction CR by both imaging and flow cytometry was associated with improved PFS and OS. Early MRD negativity (post-2 cycles) was also associated with an improved PFS but not OS. There were 3 deaths while on therapy, and grades 3 and 4 adverse events (AEs) were observed in 22% and 68% of the patients. CONCLUSION: The addition of ofatumumab to HyperCVAD/HD-MA led to high rates of MRD negativity by flow cytometry in patients with newly diagnosed MCL. Achieving a CR post-induction by both imaging and flow cytometry is associated with improved overall survival.

Patients with chronic lymphocytic leukemia (CLL) are known to be at a higher risk of developing other primary cancers (OPC). Identifying latency and risk factors associated with OPCs in CLL is of interest as select patients may potentially benefit from early treatment of CLL with targeted therapies to improve immune surveillance. In this single-center retrospective study, 16.9% of 969 patients with CLL were diagnosed with an OPC. Interestingly, 44% of OPCs were diagnosed prior to the CLL diagnosis, including 30% that were diagnosed >1 year prior. This included a majority of genitourinary cancers and melanoma skin cancers. Patients with CLL and an OPC were older than pts with no OPCs but no other risk factors for developing OPCs were identified. Our data suggest that not only are patients with CLL at higher risk of developing OPCs and warrant appropriate cancer surveillance, but the risk also precedes CLL diagnosis by several years.

BACKGROUND: The public is placing increased emphasis on specialty specific rankings, thereby affecting patients' choices of clinical care programs. In the spirit of transparency, public reporting initiatives are underway or being considered by various surgical specialties whose databases rank programs based on short-term outcomes. Of concern, short-term risk avoidance excludes important comparative cases from surgical database participation and may adversely affect overall long-term oncologic treatment team results. To assess the validity of comparing short-term perioperative and long-term survival outcomes of all patients treated at major centers, we studied the correlations between these variables. METHODS: The National Cancer Database was queried for patients diagnosed with non-small cell lung carcinoma (NSCLC) between 2008 and 2012, yielding 5-year follow-up data for all patients at centers treating at least 100 patients annually. Mortality (30- and 90-day), unplanned 30-day readmissions, and hospital length of stay were modeled using logistic regression with sex, race, age, Charlson-Deyo combined comorbidity, extent of surgery, income, insurance status, histology, grade, and analytic stage as predictors, all with 2-way interaction terms. The differences between the predicted rates and observed rates were calculated for each short-term outcome, and the average of these was used to create a short-term metric (STM). A similar approach was used to create a long-term metric (LTM) that used overall survival as a single dependent variable. Centers were ranked into deciles based on these metrics. Visual plotting as well as correlation coefficients were used to judge correlation between STM and LTM. RESULTS: A total of 298,175 patients from 541 centers were included in this analysis, of whom 102,860 underwent surgical resection for NSCLC. The correlation between STM and LTM was negative using parametric estimates (Pearson correlation coefficient = -0.09 [P = .03] and -0.22 [P < .01]) and nonparametric estimates (Spearman rank correlation coefficient = -0.09 [P = .02] and -0.22 [P < .01]) for squamous cell carcinoma and adenocarcinoma, respectively. CONCLUSIONS: Short-term perioperative outcome rankings correlate poorly with long-term survival outcome rankings when cancer treatment centers are compared. Factors explaining this discrepancy merit further study. Rankings based on short-term outcomes alone may be incomplete for public reporting.

Importance: Considering its low completion rate, the survival benefit associated with postoperative chemotherapy (PC) is unclear in patients with resectable gastric adenocarcinoma who received preoperative chemotherapy. Objective: To determine whether preoperative chemosensitivity is associated with postoperative survival among patients with resectable gastric adenocarcinoma who receive PC. Design, Setting, and Participants: This national, hospital-based cohort study used data from the National Cancer Database, which covers more than 70% newly diagnosed gastric adenocarcinomas in the US, between 2006 and 2017. Participants included patients with clinical stage II or III disease treated with preoperative chemotherapy and curative-intent resection, excluding radiotherapy. Preoperative chemosensitivity was defined as very sensitive (ypT0N0), sensitive (pathological TNM stage less than clinical, excluding ypT0N0), and refractory (pathological greater than or equal to clinical). Data were analyzed in April 2021. Exposures: Receipt of PC or not. Main Outcomes and Measures: Overall survival from surgical discharge. Results: This study included 2382 patients (1599 men [67%]; median [IQR] age, 63 [54-70] years). Most patients (1524 patients [64%]) received no PC. Most patients (1483 patients [62%]) had refractory disease, followed by sensitive disease (727 patients [31%]) and very sensitive disease (172 patients [7%]). Patients with older age (odds ratio [OR], 0.99; 95% CI, 0.97-1.00), comorbidity (OR, 0.71; 95% CI, 0.57-0.90), longer time from chemotherapy initiation to surgery (OR, 0.99; 95% CI, 0.97-1.00), less sensitivity to preoperative chemotherapy (very sensitive vs refractory OR, 0.58; 95% CI, 0.37-0.89; sensitive vs refractory OR, 0.96; 95% CI, 0.76-1.20), and longer surgical hospitalization (OR, 0.95; 95% CI, 0.93-0.97) had a significantly lower likelihood of receiving PC. PC was not associated with improved survival in the whole group (hazard ratio [HR], 0.88; 95% CI, 0.75-1.02). Patients with refractory disease had the worst survival compared with patients with sensitive disease (HR, 0.39; 95% CI, 0.32-0.46) and those with very sensitive disease (HR, 0.12; 95% CI, 0.07-0.20). Preoperative chemosensitivity was significantly associated with the survival benefit from PC (P for interaction = .03). PC was significantly associated with longer survival in patients with sensitive disease (5-year survival rate, 73.8% in the PC group vs 65.0% in the no PC group; HR, 0.64; 95% CI, 0.46-0.91), but not in those with very sensitive disease (5-year survival rate, 80.0% in the PC group vs 90.8% in the no PC group; HR, 2.45; 95% CI, 0.81-7.43) and those with refractory disease (5-year survival rate, 41.8% in the PC group vs 40.7% in the no PC group; HR, 0.93; 95% CI, 0.79-1.10). Conclusions and Relevance: In this cohort study, preoperative chemosensitivity was associated with survival among patients with resectable gastric adenocarcinoma who received PC. These findings may help inform future studies to personalize postoperative therapy.

The association between HRQOL metrics and survival has not been studied in early stage non-small-cell lung cancer (NSCLC) patients undergoing SBRT. The cohort was derived via a post-hoc analysis of a prospective randomized clinical trial examining definitive SBRT for peripheral, early-stage NSCLC with a single or multi-fraction regimen. Patients completed HRQOL questionnaires prior to and 3 months after treatment. Using principal component analysis (PCA), changes in each HRQOL scale following treatment were reduced to two eigenvectors, PC1 and PC2. Cox regression was employed to analyze associations with survival-based endpoints. A total of 70 patients (median age 75.6 years; median follow-up 41.1 months) were studied. HRQOL and symptom comparisons at baseline and 3 months were vastly unchanged except for improved coughing (p = 0.02) and pain in the chest at 3 months (p = 0.033). PC1 and PC2 explained 21% and 9% of variance, respectively. When adjusting for covariates, PC1 was significantly correlated with progression-free (PFS) (HR = 0.78, 95% CI 0.67-0.92, p = 0.003) and overall survival (OS) (HR = 0.76, 95% CI 0.46, p = 0.041). Changes in global health status, functional HRQOL performance, and/or symptom burden as described by PC1 values are significantly associated with PFS and OS. The PC1 quartile may facilitate the identification of at-risk patients for additional interventions.
RESUMEN
In this phase I, dose-escalation study, we sought to determine the maximum tolerated dose (MTD) of the anaplastic lymphoma kinase/c-ROS oncogene 1 receptor (ALK/ROS1) inhibitor ceritinib in combination with gemcitabine-based chemotherapy in patients with advanced solid tumors. Secondary objectives were characterization of the safety profile, pharmacokinetics and preliminary efficacy of these combinations, and identification of potential biomarkers of efficacy. Ceritinib was combined with gemcitabine (Arm 1), gemcitabine/nab-paclitaxel (Arm 2) or gemcitabine/cisplatin (Arm 3). Drug concentrations in plasma were measured by tandem mass spectrometric detection (LC-MS/MS). We analyzed archival tumor tissue for ALK, ROS1, hepatocyte growth factor receptor (c-MET) and c-Jun N-terminal kinase (JNK) expression by immunohistochemistry. Arm 2 closed early secondary to toxicity. Twenty-one patients were evaluable for dose-limiting toxicity (DLT). There was one DLT in Arm 1 (grade 3 ALT increase) and three DLTs in Arm 3 (grade 3 acute renal failure, grade 3 thrombocytopenia, grade 3 dyspnea). The MTD of ceritinib was determined to be 600 mg (Arm 1) and 450 mg orally daily (Arm 3). Main toxicities were hematologic, constitutional and gastrointestinal as expected by the chemotherapy backbone. The apparent clearance for ceritinib decreased substantially after repeated dosing; cisplatin did not significantly affect the pharmacokinetics of ceritinib. The overall response rate was 20%; the median progression-free survival was 4.8 months. Three out of five response-evaluable cholangiocarcinoma patients had clinical benefit. Increased expression of c-MET was associated with a lack of clinical benefit. Ceritinib in combination with gemcitabine and gemcitabine/cisplatin has a manageable toxicity profile. Further development of this strategy in tumors with ALK or ROS1 fusions is warranted.

BACKGROUND: The incidence and prevalence of neuroendocrine neoplasms (NENs) are rapidly rising. Epidemiologic trends have been reported for common NENs, but specific data for lung NENs are lacking. METHODS: We conducted a retrospective analysis utilizing the Surveillance, Epidemiology, and End Results (SEER) database. Associated population data were utilized to report the annual age-adjusted incidence and overall survival (OS) trends. Trends for large-cell neuroendocrine carcinoma (LCNEC) and atypical carcinoid (AC) were reported from 2000-2015, while those for typical carcinoid (TC) and small cell lung cancer (SCLC) were reported from 1988-2015. RESULTS: We examined a total of 124,969 lung NENs [103,890-SCLC; 3303-LCNEC; 8146-TC; 656-AC; 8974-Other]. The age-adjusted incidence rate revealed a decline in SCLC from 8.6 in 1988 to 5.3 in 2015 per 100,000; while other NENs showed an increase: TC increased from 0.57 in 1988 to 0.77 in 2015, AC increased from 0.17 in 2001 to 0.22 in 2015, and LCNEC increased from 0.16 in 2000 to 0.41 in 2015. The 5-year OS rate among SCLC, LCNEC, AC, and TC patients was 5%, 17%, 64%, and 84%, respectively. On multivariable analyses, OS and disease-specific survival (DSS) varied significantly by stage, sex, histological type, insurance type, marital status, and race, with a better survival noted in earlier stages, females, married, insured, Hispanic and other races, and urban population. Similarly, TC and AC had better survival compared to SCLC and LCNEC. CONCLUSION: The incidence of lung NENs is rising, possibly in part because of advanced radiological techniques. However, the incidence of SCLCs is waning, likely because of declining smoking habits. Such population-based studies are essential for resource allocation and to prioritize future research directions.
RESUMEN
BACKGROUND: In patients with clinical N1 disease, minimally invasive surgery (MIS) has potentially better perioperative outcome compared to open thoracotomy. Additionally, whether adjuvant or neoadjuvant chemotherapy produces the best long-term survival is still debatable. METHODS: We queried The National Cancer Database for patients with clinical N1 NSCLC who underwent surgical resection between 2010 and 2014. Comparison between patients receiving MIS and patients who underwent open thoracotomy was done using an intention-to-treat analysis. Comparison was also done among neoadjuvant, adjuvant chemotherapy, and only surgery. Proportional hazard models were used to evaluate the effects of surgical approach and timing of chemotherapy on overall survival. RESULTS: A total of 1440 and 3942 patients underwent MIS and open thoracotomy respectively. MIS achieved better surgical margins (90.0% versus 88.6%) and shorter length of stay (6.5 ± 6.5 versus 7.3 ± 6.4 d, P ≤ 0.01) compared to open thoracotomy. There were no differences in 30-day and 90-day mortality, nor readmission rates. Neoadjuvant and adjuvant chemotherapy were administered to 13.5% and 57.2% of patients respectively. There was no significant difference in the 5-year overall survival between MIS and open thoracotomy (46% versus 46% P = 0.08). There was significantly better 5-year overall survival in neoadjuvant and adjuvant chemotherapy versus only surgery, but no difference between neoadjuvant and adjuvant chemotherapy (48% versus 47% versus 44%, P < 0.01). CONCLUSIONS: In clinical N1 NSCLC, MIS does not compromise oncological quality or overall survival when compared to open thoracotomy. Overall survival improved in patients treated with chemotherapy but there is no difference when given as neoadjuvant versus adjuvant chemotherapy.

BACKGROUND AND OBJECTIVES: Pasireotide was shown in a randomized trial to decrease the rate of postoperative pancreatic fistula (POPF). However, retrospective series from other centers have failed to confirm these results. METHODS: Patients who underwent pancreatoduodenectomy or distal pancreatectomy between January 2014 and February 2019 were included. Patients treated after November 2016 routinely received pasireotide and were compared to a retrospective cohort. Multivariate analysis was performed for the outcome of clinically relevant POPF (CR-POPF), with stratification by fistula risk score (FRS). RESULTS: Ninety-nine of 300 patients received pasireotide. The distribution of high, intermediate, low, and negligible risk patients by FRS was comparable (P = .487). There were similar rates of CR-POPF (19.2% pasireotide vs 14.9% control, P = .347) and percutaneous drainage (12.1% vs 10.0%, P = .567), with greater median number of drain days in the pasireotide group (6 vs 4 days, P < .001). Multivariate modeling for CR-POPF showed no correlation with operation or pasireotide use. Adjustment with propensity weighted models for high (OR, 1.02, 95% CI, 0.45-2.29) and intermediate (OR, 1.02, CI, 0.57-1.81) risk groups showed no correlation of pasireotide with reduction in CR-POPF. CONCLUSIONS: Pasireotide administration after pancreatectomy was not associated with a decrease in CR-POPF, even when patients were stratified by FRS.

Background: Xerostomia occurs in the majority of patients undergoing chemoradiation therapy for head and neck cancer (HNC). Acupuncture-like transcutaneous electrical nerve stimulation (ALTENS) treatment has been studied as an encouraging modality to improve salivary function and related symptoms. The purpose of this study was to compare ALTENS treatment by using a four-times weekly schedule for 6 weeks versus a twice-weekly schedule for 12 weeks with a validated xerostomia scale at 15 months from the start of ALTENS treatment. Materials and Methods: This single-center randomized study was conducted in 30 patients treated with radiotherapy with or without chemotherapy for HNC between 2014 and 2017, who had at least grade 1 or 2 symptomatic dry mouth (xerostomia) according to CTEP NCI Common Terminology Criteria for Adverse Events (CTCAE version 4.0). These patients were randomly assigned to receive ALTENS four-times weekly for 6 weeks or two-times weekly for 12 weeks. The University of Michigan 15-item Xerostomia-related Quality of Life Scale (XeQoLS) was administered at 6, 9, 15, and 21 months from the start of ALTENS treatment. A random-effects generalized linear model was used to model the overall XeQoLS score at the 15-month endpoint; adjusted for a random time effect, a fixed treatment arm, and interaction of time and treatment. Comparison between arms was based on a 0.05 nominal significance level. Results: XeQoLS decreased for all patients (although not statistically for each arm) from a mean of 22 and 21 at baseline (in the four times per week and twice weekly arms) to 12 in both arms at 15 months, with no difference between arms (p = 0.68). There were no attributable grade 1-3 adverse events. Arms were balanced for age, gender, race, and baseline xerostomia. Conclusions: This study demonstrates that both ALTENS regimens are safe, well tolerated, and appear to be equally effective. We now routinely make ALTENS units available for home use.

There is a paucity of data regarding outcomes and response to standard therapy in patients with limited-stage (LS) agressive B-cell lymphoma (LS-ABCL) who harbor MYC rearrangement (MYC-R) with or without BCL2 and/or BCL6 rearrangements. We conducted a multicenter retrospective study of MYC-R LS-ABCL patients who received either rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP), or more intensive immunochemotherapy (IIC) plus or minus consolidative involved-field radiation therapy (IFRT). One hundred four patients from 15 academic centers were included. Forty four patients (42%) received R-CHOP, of whom 52% had IFRT. Sixty patients (58%) received IIC, of whom 40% had IFRT. Overall response rate was 91% (84% complete response [CR]; 7% partial response). Patients with double-hit lymphoma (DHL; n = 40) had a lower CR rate compared with patients with MYC-R only (75% vs 98%; P = .003). CR rate was higher in the IFRT vs no-IFRT group (98% vs 72%; P < .001). Median follow-up was 3.2 years; 2-year progression-free survival (PFS) and overal survival (OS) were 78% and 86% for the entire cohort, and 74% and 81% for the DHL patients, respectively. PFS and OS were similar across treatment groups (IFRT vs no IFRT, R-CHOP vs IIC) in the entire cohort and in DHL patients. Our data provide a historical benchmark for MYC-R LS-ABCL and LS-DHL patients and show that outcomes for this population may be better than previously recognized. There was no benefit of using IIC over R-CHOP in patients with MYC-R LS-ABCL and LS-DHL.
